1 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
4 This is quite important since the latter clears the
5 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
6 every single character read...
8 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
10 * print.c (scm_iprin1): Removed suspect looking (and indeed
11 malevolent) semicolon after test for user supplied closure print
12 procedure. (Thanks to Telford Tendys.)
14 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
15 (scm_memq, scm_memv, scm_member): Do argument checking *before*
16 starting to search the list. Removed call to sloppy_mem_check.
18 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
19 procedures: Same as scm_delq_x et al, but delete maximally one
22 * options.c (scm_options, scm_init_options): GC-protect option
23 values of type SCM. (Thanks to Telford Tendys.)
25 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
27 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
28 make sure that there always is a "real" scm_lookupcar.
30 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
32 * read.c, read.h (history-length, history-file): New read options.
33 (scm_read_options): Stifle history to history length.
35 * readline.c (read-history, write-history): New procedures.
37 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
39 * eval.h (scm_macro_eval_x): Removed declaration.
41 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
42 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
43 Renamed and made global.
45 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
46 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
48 * evalext.c, evalext.h: New files. Contain non-R5RS things
49 having to do with evaluation.
51 * evalext.c (serial-map): New procedure: Version of `map' which
52 guarantees that the procedure is applied to the lists in serial
54 (sequence->list): New syntax: Version of `begin' which returns a
55 list of the results of the body forms instead of the result of the
57 (scm_definedp, scm_m_undefine): Moved from eval.c
59 * evalext.h (scm_m_sequence_to_list): Added declaration.
61 * macros.c, macros.h: New files.
62 (procedure->syntax, procedure->macro, procedure->memoizing-macro,
63 macro?, macro-type, macro-name, macro-transformer): Moved from
65 (scm_make_synt): Moved from eval.c
67 * procs.c, procs.h (procedure-documentation): Moved from eval.c.
69 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
72 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
74 * debug.c, print.c: Added #include "macros.h".
76 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
78 This change adds the ability to use `unread-char' multiple times
79 without interspersed reads and adds the new procedure
80 `unread-string'. The change is optimized for the common case of
81 unreading a single character. This is also the reason behind the
82 choice to store characters in the port itself: in most cases no
83 extra malloc is required.
85 The amount of code in some macros in ports.h has been increased to
86 the extent that they would fit better as C functions, but, since
87 this code belongs to the port representation, such functions
88 should be placed in ports.c which would cause calls back and forth
89 between ports.c and genio.c. That is not good for performance.
90 Also, keeping them as macros allows the compiler to do some
91 optimizations which are needed to make the current interface
92 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
94 One benchmark (Guile startup time) indicates an increase of
95 loading speed of 1%. Another (reading (using `read') boot-9.scm
96 10 times) shows no change in performance.
98 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
99 made to find a beautiful solution.)
101 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
102 (SCM_TRY_CLRDY): New macro: Only clear the first unread
103 character. (SCM_CLRDY clears all.)
104 (SCM_N_READY_CHARS): New macro: Returns number of unread
105 characters in a port. Returns wrong answer if SCM_CRDYP is false.
106 (struct scm_port_table): New fields: `entry' contains port table
107 index, `cp' points to last unread char, `cbuf' is the buffer for
108 unread chars, `cbufend' points after end of the character buffer.
110 * ports.h, ports.c (scm_unread_string): New procedure.
111 (scm_grow_port_cbuf): New function.
113 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
115 (scm_generic_fgets), fports.c (local_fgets): Use a loop
116 to read unread characters. Use SCM_TRY_CLRDY instead of
119 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
121 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
123 * genio.c, genio.h (scm_ungets): New function.
125 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
128 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
130 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
131 declarations. (Thanks to Russ McManus.)
133 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
135 * numbers.c (num2long): As a software archeologist, I'm proud of
136 this finding! :) Preliminary dating suggests an almost 4 year old
137 remnant from the SCM ancestor. The sample has been removed from
138 the finding site and is now safely stored in the repository.
140 * numbers.h: Removed prototype for num2long.
142 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
144 * gh_data.c (gh_scm2doubles): Make it possible to pass result
146 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
147 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
148 * gh.h: Updated and added prototypes.
150 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
152 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
154 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
156 * guile-snarf.in: Never generate an empty file. (Thanks to
159 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
160 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
161 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
162 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
163 gh_new_procedure5_0): Specify argument types, to appease C++
164 compilers. (Thanks to Brad Bowman.)
166 Bug reports from Russ McManus:
167 * guile-snarf.in: If the CPP environment variable is set, use that
168 as the C preprocessor, instead of the preprocessor autoconf
170 * snarf.h (SCM_PROC): Cast the function pointer passed to
171 scm_make_gsubr, to satisfy C++.
173 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
174 Use the handler passed, instead of ignoring it and using
175 gh_standard_handler. (Thanks to Etienne Bernard.)
177 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
179 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

199 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
202 * script.c (scm_compile_shell_switches): Define
203 use-emacs-interface in the root module, so the repl code can see
204 it. See today's change to top-repl in ice-9/boot-9.scm.
206 * filesys.c (set_element, get_element): Make sure that `element'
207 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
208 Boekemeier and Jorgen "forcer" Schaefer.)
210 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
212 * chars.c (scm_charnames): In ASCII character name table, make
213 newlines print as #\newline by default, not #\nl.
215 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
216 alphabetical order. Oh thrills. But it helps me know how far
217 along in the compilation I am.
218 * Makefile.in: Regenerated.
220 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
222 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
223 #bytes(...) to #y(...), and syntax for short vectors from
224 #short(...) to #h(...). This may seem nutty, but, like the other
225 uniform vectors, byte vectors and short vectors want to have the
226 same print and read syntax (and, more basic, want to have read
227 syntax!). Changing the read syntax to use multiple characters
228 after the hash sign breaks with the conventions used in R5RS and
229 the conventions used for the other uniform vectors. It also
230 introduces complexity in the current reader, both on the C and
231 Scheme levels. (The Right solution is probably to change the
232 syntax and prototypes for uniform vectors entirely.)
234 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
236 Don't use local_fgets on sockets; ftell doesn't work on sockets.
237 (Thanks to Jorgen "forcer" Schaefer.)
238 * ports.h (SCM_NOFTELL): New flag.
239 * fports.c (local_fgets): If it's set, use the generic fgets.
240 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
242 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
244 * script.c (scm_compile_shell_switches): Add handling of -q switch
245 (inhibit loading of user init file).
246 (scm_shell_usage): Add usage text for -q switch.
247 (scm_compile_shell_switches): Always load user init file first if
250 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
252 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
253 and is now broken under NetBSD. I can't fathom what it's trying
254 to do, so I've replaced it with something that I do understand,
255 which seems to work, and which isn't broken on NetBSD. "Progress?
256 You Decide." (Thanks to Perry Metzger.)
258 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
259 signed/unsigned comparison.
261 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
263 Warning fixes from Greg Harvey:
264 * unif.c (scm_array_set_x): initializer for pos
265 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
266 * struct.c (scm_struct_ref, scm_struct_set_x): Added
267 initializers for field_type, since EGCS so desparately wants to
269 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
270 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
271 when GUILE_DEBUG is defined.
272 * dynwind.h (scm_wind_chain): Same.
273 * ports.h (scm_pt_size, scm_pt_member): Same.
274 * print.h (scm_current_pstate): Same.
275 * procs.h (scm_make_cclo): Same.
277 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
279 Handle short and long long uniform arrays properly. (Thanks to
281 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
282 raeql_1): Add cases for scm_tc7_svect (short vectors) and
283 scm_tc7_llvect (long long vectors).
285 Change the way libguile and boot-9.scm are timestamped, to try to
286 get rid of these spurious mismatch warnings. Now both
287 libguile/versiondat.h and ice-9/version.scm are generated directly
288 by the configuration process, rather than having version.scm
289 generated directly, and libguile/versiondat.h generated by the
290 Makefile, which is generated by configure. It seems that
291 sometimes the Makefile would change, but versiondat.h depends on
292 Makefile.in, not Makefile, so it wouldn't get rebuilt.
293 * Makefile.am (versiondat.h): Target removed; this is generated
294 directly by the configure script now.
295 (BUILT_SOURCES): Remove versiondat.h.
296 * versiondat.h.in: New file, transformed by the configure script
298 * Makefile.in: Regenerated.
300 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
301 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
302 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
303 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
304 if we want to use them in a header file some day, we can. (Thanks
307 * stime.c (scm_get_internal_real_time): Do the arithmetic using
308 SCM numbers, so we won't have rollover problems; the range of a
309 signed long in milliseconds is about 25 days. (Thanks to Karl
312 Don't redefine sleep and usleep; fix this problem now.
313 * coop.c (sleep, usleep): Remove declarations; we don't use or
314 redefine these any more.
315 (scm_thread_usleep, scm_thread_sleep): New functions which do the
316 job of usleep and sleep in a thread-friendly way. We can use
317 these in the rest of Guile. Define versions for systems both with
319 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
320 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
321 we're just using it, not redefining it, we can use a K&R style
323 (sleep): Declare this, too, if the system hasn't.
324 (scm_sleep, scm_usleep): Use scm_thread_sleep and
325 scm_uthread_sleep if they're available; otherwise, just call the
327 * scmconfig.h.in: Regenerated.
329 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
331 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
333 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
335 * threads.c: Doc fix.
337 The argument type of usleep varies from system to system,
338 as does the return type. We really shouldn't be redefining usleep
339 at all, but I don't have time to clean that up before the 1.3.
340 release. It's on the schedule for afterwards. (Thanks to Julian
342 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
344 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
345 * scmconfig.h: Regenerated.
347 * simpos.c (scm_software_type): Procedure deleted. This isn't the
348 right way to handle system variation. Autoconf's approach is the
350 * simpos.h (scm_software_type): Declaration deleted.
352 * script.c (scm_find_executable): Don't test if unix is #defined
353 here; first, NetBSD doesn't #define it, and second, it's the wrong
354 way to go about these things. (Thanks to Perry Metzger.)
355 (dld_find_executable): Delete this MSDOS support code. This isn't
356 the way we want to support this; it needs to be rethunk at a
359 * genio.c (scm_do_read_line): Don't just politely check that the
360 line was either non-empty or EOF. Abort if it's empty and not
363 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
365 * scmconfig.h.in: Regenerated.
367 * libguile.h: Don't omit the dynamic linking functions. (Thanks
370 * genio.c (scm_do_read_line): Count lines correctly when the file
371 doesn't end in a newline.
373 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
375 * genio.c (scm_do_read_line): Maintain the line count correctly.
376 (Thanks to Harvey J. Stein and Greg Harvey.)
378 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
381 * numbers.c (big2str): Protect t from garbage collection until
382 we're done. (Thanks to Gary Houston.)
384 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
386 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
388 * Makefile.in: Regenerated.
390 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
391 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
394 Do magic to mix reads and writes on stdio FILE-based ports.
395 (Thanks to Christian Lynbech.)
396 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
398 (pre_read, pre_write): New functions.
399 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
400 local_fputs): Call them.
401 (local_fflush): Mark the port as ready for reading and writing.
402 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
403 flags on new port objects. This might not be accurate --- who
404 knows what state the FILE * is in when we get it --- but it won't
405 do extraneous calls to fflush or fseek, so it's no worse than the
406 behavior before this change.
407 * ports.h: Add comment.
409 Centralize the creation of port objects based on stdio FILE * in
410 fports.c; don't just throw them together anywhere.
411 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
412 what the rest of Guile wants. Don't set the revealed count;
413 that's only appropriate for stdin, stdout, stderr.
414 (scm_standard_stream_to_port): This function does set the revealed
416 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
417 not scm_stdio_to_port.
418 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
419 * fports.c (scm_open_file): Same.
420 * posix.c (scm_pipe): Same.
421 * socket.c (scm_sock_fd_to_port): Same.
422 * ioext.c (scm_fdopen): Same.
423 (scm_freopen): Moved from here to...
424 * fports.c (scm_freopen): ... here. This is really something that
425 munges the internals of an fport, so it should go here.
426 * fports.h (scm_stdio_to_port): Adjust prototype.
427 (scm_standard_stream_to_port, scm_freopen): New protoypes.
428 * ioext.h (scm_freopen): Prototype removed.
430 * filesys.c (set_element, get_element): This can work on both pipe
431 and file ports, so use SCM_FPORTP to typecheck, instead of testing
434 * scmconfig.h.in: Regenerated.
436 Change the definition of the functions in scm_ptobfuns so that
437 they get passed the port object, not the port's stream.
438 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
439 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
440 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
441 Pass the port itself to the scm_ptobs function.
442 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
443 scm_generic_fgets): Same.
444 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
445 getc_void_port, fgets_void_port, close_void_port): Just change the
446 argument names; these functions don't really do anything.
447 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
448 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
449 port as an argument, and use SCM_STREAM to get the stdio FILE *.
450 Also, use prototyped definitions, and get rid of the extra
452 (scm_fptob, scm_pipob): We don't need casts here any more.
453 * strports.c (prinstpt): Use prototype declarations.
454 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
455 and use SCM_STREAM to get the string info. Also, use prototyped
456 definitions, and get rid of the extra declarations.
457 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
460 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
461 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
463 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
464 scm_fgets, for consistency.
465 (scm_fptop, scm_pipob): References updated.
467 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
469 Include the source location in error messages for scripts.
470 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
471 stack is still there when we catch the error.
472 * throw.c (handler_message): If we are handling an error with a
473 message, then put together the proper arguments and call
474 scm_display_error, instead of scm_display_error_message. That
475 displays source location, if it can find it.
477 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
479 * gc.c (scm_unprotect_object): Change this so that calls to
480 scm_protect_object and scm_unprotect_object nest properly.
481 (scm_protect_object): Doc fixes.
483 * strings.c (scm_string_set_x): Require the argument to be a
484 writable string, not a substring or a symbol.
485 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
486 (Thanks to John Redford and Charbel Jacquin.)
488 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
490 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
492 * eval.c (safe_setjmp): Remove this misunderstanding.
493 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
496 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
498 * libguile.h: Mark these as C declarations, for compilation by C++
501 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
502 __cplusplus clause. I seriously doubt this ever worked the way
503 the author seems to have intended.
505 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
507 Utterly needless cleanups to hopelessly messy code.
508 * ports.c: Doc fixes.
509 (scm_fflush): Moved to ...
510 * genio.c (scm_fflush): ... here, amongst all the other port
511 method invocation functions.
512 * genio.h, ports.h: The prototype moves too.
514 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
516 * backtrace.c (display_error_body): The current frame does not
517 always have a parent frame; consider a function called directly
518 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
521 * alloca.c (alloca): Undo yesterday's changes, and simply call
522 malloc directly for storage, and abort if we don't get what we
523 want. The situation is much simpler --- just call malloc. Emacs
524 has bizarre/evil requirements (signal handlers might malloc unless
525 you set this global flag, so you have to set the flag around all
526 calls to malloc) which we are certainly not going to conform to,
527 so we can do the simple and obvious thing.
529 * coop.c (coop_condition_variable_wait): Make this function
530 static. It's only useful internally --- you should never just
531 wait on a condition variable.
532 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
534 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
536 * unif.c (scm_array_set_x): Accept any kind of number as an
537 element for a uniform vector of doubles. This is more consistent
538 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
540 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
541 works; I can't conveniently test it myself. (Thanks to Dvid
542 Tillman for the bug report.)
546 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
547 from here, not from scm_compile_shell_switches (which is a pretty
548 dumb place to do it).
549 (scm_load_startup_files): New function.
550 (scm_ice_9_already_loaded): Variable moved to here from script.c.
551 * script.c (scm_compile_shell_switches): Don't load the startup
553 (scm_ice_9_already_loaded): Variable moved.
554 * init.c (scm_load_startup_files): Prototype for new function.
555 * gh_init.c (gh_enter): Doc fix.
557 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
559 Some anti-warning changes from Greg Harvey.
560 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
561 warnings when it doesn't understand our NORETURN declarations in
563 * posix.c (scm_mknod): Similar.
565 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
567 * posix.c (scm_getpwuid): If we can't find an entry, return our
568 own message, instead of using scm_syserror --- the getpwMUMBLE
569 functions don't set `errno' to anything interesting.
571 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
573 Get rid of warnings from the cooperative threading system.
574 * threads.h (scm_single_thread_p, scm_yield,
575 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
576 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
577 scm_wait_condition_variable, scm_signal_condition_variable): Add
578 prototypes for these Scheme-visible functions.
579 * coop-defs.h (coop_next_runnable_thread,
580 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
581 Prototypes for these here, even though they're from iselect.c.
582 (coop_condition_variable_wait, coop_join): Add prototypes.
583 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
584 scm_threads_free_condvar): Make these smob functions static.
585 * coop-threads.h (coop_init): Give this a real prototype.
586 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
587 (coop_next_runnable_thread): No need to provide prototype; it's in
590 * scmconfig.h.in: .detarenegeR
592 * iselect.c, threads.c: Doc fixes.
594 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
596 * Makefile.in: Regenerated with a patched automake, to get
597 dependency generation right when using EGCS.
599 * inet_aton.c (inet_aton): Add prototype, to remove compiler
600 warning. (Thanks to Robert Pluim.)
602 * inet_aton.c (inet_aton): Reassure the compiler that the
603 arguments to the <ctype.h> macros are all unsigned characters, not
606 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
608 Getting rid of more warnings...
609 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
610 today's change to ../configure.in.
611 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
612 * scmconfig.h.in: Regenertaded.de.,.__
613 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
614 (scm_localtime, scm_mktime): Use a const char * to manipulate the
617 * readline.c: Doc fix.
618 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
619 * readline.h (scm_filename_completion_function): Add prototype.
620 (scm_init_readline): Make this into a prototype.
622 * readline.c (scm_filename_completion_function): Use SCM_PROC to
623 declare this, instead of calling scm_make_subr manually.
625 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
627 * readline.h (scm_init_readline): Add prototype for this.
628 (scm_init_readline): Make this a real prototype.
630 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
632 Warning fixes from Maciej Stachowiak:
633 * backtrace.h (scm_display_application, scm_backtrace): Add
635 * debug.c (scm_m_start_stack): Make this function static.
636 * fluids.h (scm_fluid_p): Add prototype.
637 * procprop.c (scm_i_procedure_arity): Make this function static.
638 * regex-posix.c (scm_regexp_error_msg): Make this function static.
639 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
640 * root.h (scm_dynamic_root): Add external prototype.
641 * scmsigs.h (scm_usleep): Add external prototype.
642 * script.h (scm_init_script): Use prototype, not K&R decl.
643 * stacks.h (scm_stack_id): Add external prototype.
644 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
646 1998-09-30 Mark Galassi <rosalia@cygnus.com>
648 * gh.h: took out the definitions of vset and vref, since they are
649 replaced by the proper vector routines that correspond to the R4RS
652 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
654 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
655 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
656 third argument, a C expression that should result in a SCM value,
657 which is used to initialize the variable. Reimplemented
658 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
661 * version.h (scm_libguile_config_stamp): Add prototype.
662 (From Maciej Stachowiak.)
664 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
666 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
667 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
669 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
671 * print.c (scm_iprin1): Rather than having one i, and using it in
672 several places, declare a fresh i local to each block where it is
673 used, and give it a signedness appropriate to its use in each case.
676 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
679 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
680 signed/unsigned clashes.
682 * posix.h (scm_tmpnam): Added prototype.
684 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
685 scm_make_subclass_object): Add external prototypes.
687 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
688 comparison is okay here.
690 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
692 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
693 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
695 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
698 * load.c (swap_port): Make this function static.
700 * load.c (scm_search_path): Make max_path_len and max_ext_len
701 unsigned, since they're compared against string sizes.
703 * load.c (init_build_info): Make i unsigned.
705 * ioext.h (scm_read_line): Add prototype.
707 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
708 scm_hash_fn_remove_x): Make hash bucket index local variable k
709 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
710 accurately as possible.
712 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
713 comparisons, and range checking to make sure those casts are
716 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
717 signed/unsigned comparisons.
719 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
720 avoid signed/unsigned comparisons.
721 * smob.h (scm_numsmob): Change extern declaration to match.
723 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
724 avoid signed/unsigned comparisons.
725 * ports.h (scm_numptob): Change extern declaration to match.
726 (scm_current_load_port, scm_set_port_line_x,
727 scm_set_port_column_x): New prototypes.
729 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
730 test code, and it causes warnings.
732 * gh.h (gh_int2scmb, gh_uniform_vector_length,
733 gh_uniform_vector_ref): Added prototypes.
735 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
736 debugging support unconditionally. That's backtrace.c, stack.c,
737 debug.c, and srcprop.c.
738 (EXTRA_libguile_la_SOURCES): Omit those from here.
739 * Makefile.in: Regenerated.
741 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
743 * options.c (scm_options): Bugfix: Allow empty list of options!
745 * debug.c, debug.h (scm_single_step): Removed.
746 (scm_with_traps): New procedure. This procedure could easily be
747 written in Scheme but needs to be highly optimized.
749 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
751 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
752 Check SCM_TRAPS_P before trapping.
754 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
756 Changes to avoid signed/unsigned comparison warnings.
757 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
758 (scm_gc_sweep): Make n and j local to the blocks they're used in,
759 so they can have appropriate types for each application. Make i
760 signed. Use initializers in some spots. I'll probably pay for
762 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
763 (scm_must_realloc): Make nm unsigned.
764 (init_heap_seg): Make new_seg_index and n_new_objects signed.
765 (scm_init_storage): Use prototype-style definition, and make the
767 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
768 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
770 * filesys.c (scm_readlink): Make local vars rv and size ints, to
771 avoid signed/unsigned comparison warnings, and because the return
772 value of readlink may be -1. Don't bother casting the third
773 argument to readlink.
775 * filesys.c (scm_dirname, scm_basename): Move these to their own
776 page, at the end of the file.
777 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
779 * eval.h (scm_eval_options_interface): Add external prototype for this.
780 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
782 * eval.c (scm_lookupcar1): Make this static.
784 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
785 Make these prototype declarations, not K&R-style.
787 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
788 unsigned comparison warning.
790 * appinit.c: File removed. It had a single function in it, empty,
791 whose reason for existence is explained in no documentation or
792 comment. I think it's there as a default for some Tcl-style
793 initialization, but Tcl abandoned that approach a while ago.
794 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
795 (BUILT_SOURCES): Remove appinit.x.
796 * Makefile.in: Regenerated.
798 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
800 * Makefile.in: Regenerated using the last public version of
801 automake, not the hacked Cygnus version.
803 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
805 Remove Totoro kludge.
806 * Makefile.in, scmconfig.h.in: Regenerated.
807 * init.c, readline.c: Don't check if TOTORO is #defined.
809 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
811 * Makefile.am: Adjust for new thread configuration system.
812 (INCLUDES): Include the value of THREAD_CPPFLAGS.
813 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
815 (THREAD_LIBS): Definition deleted; automake will generate such
816 things automatically.
817 * Makefile.in: Regenerated.
819 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
821 Simplify smob and port marking; set the mark bit in the generic
822 marking code, and make marker routines only responsible for
823 turning up outgoing pointers.
824 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
825 before calling the marking function. Don't call the marking
826 function if it's zero.
827 * markers.c (scm_mark0): Just return #f. This function isn't
828 necessary at all now, but it's harmless to call it. We'll leave
829 it in so other folks' code doesn't croak at link time.
830 (scm_markcdr): Don't call SCM_SETGC8MARK.
831 * async.c (mark_async): Don't call SCM_SETGC8MARK.
832 * dynl.c (mark_dynl_obj): Same.
833 * root.c (mark_root): Same.
834 * srcprop.c (marksrcprops): Same.
835 * unif.c (markra): Same.
836 * variable.c (scm_markvar): Same.
837 * ports.c (scm_markstream): Same.
838 (void_port_ptob): Specify zero for our marking function.
839 * debug.c (debugobjsmob): Same.
840 * dynwind.c (guardsmob): Same.
841 * filesys.c (dir_smob): Same.
842 * fluids.c (fluid_smob): Same.
843 * fports.c (scm_fptob, scm_pipob): Same.
844 * mallocs.c (mallocsmob): Same.
845 * regex-posix.c (regex_t_smob): Same.
846 * smob.c (freecell, flob, bigob): Same.
847 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
848 * throw.c (jbsmob, lazy_catch_funs): Same.
850 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
852 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
853 scm_copy_tree on code in order not to let memoized code to leak
854 out. Thus, scm_copy_tree needs to copy vectors as well since
855 quasiquote can introduce evaluated code also inside vector
858 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
860 * eval.c (scm_copy_tree): Removed ability to copy vectors.
862 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
863 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
866 * unif.c: Say that ivect and uvect are of type signed and unsigned
867 long instead of int in commentary so that it correctly describes
870 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
872 * stime.c: Removed declaration of strptime. (It should be
873 declared by the system headers. If it turns out that some systems
874 don't, we'll handle that then.) (Thanks to Greg Troxel.)
876 * stime.h: Renamed TIMEH --> STIMEH
878 * backtrace.c (scm_display_error, scm_display_backtrace): In order
879 to increase portability, don't use structure assignment.
880 (Thanks to Nicolas Neuss.)
882 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
884 (finalize_fd_sets): Added empty statement after last case label.
885 (Thanks to Nicolas Neuss.)
887 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
890 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
892 * init.c, readline.c: OK, I won't have these readline.x bug
893 reports anymore. We've had them since April. The current reason
894 is a completely unintelligible failure of totoro.red-bean.com to
895 do the test for rl_getc_function in libreadline correctly. This
896 kludge overrides the test if we're on totoro so that the snapshot
897 generation process can work.
899 * readline.c: Define a strdup replacement if not existent on system.
901 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
903 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
904 This change makes scm_make_vector R5RS compatible. We cannot keep
905 the third argument since people want to be able to deduce the form
906 of the C function call only by looking at R5RS. (At the same time
907 we have removed some unnecessary complexity!)
909 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
910 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
911 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
912 argument in call to scm_make_vector.
914 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
916 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
917 This macro is useful in applications.
919 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
921 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
922 (scm_parse_path, scm_search_path): New Scheme level procedures.
924 * load.h (scm_internal_parse_path, scm_parse_path,
925 scm_search_path): Declared.
927 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
929 * filesys.c (dirname, basename): New procedures.
931 * init.c (scm_boot_guile_1): Removed condition around
934 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
935 new data type (guards) for representation of C level guards and
936 data on the wind chain.
937 (scm_internal_dynamic_wind): New function.
939 * dynwind.h: Declare scm_internal_dynamic_wind.
941 * root.h (scm_root_state): Added scm_cur_loadp.
943 * root.c (mark_root): Added comment about cur_loadp.
945 * load.c: #include "dynwind.h";
946 (scm_primitive_load): Use scm_inner_dynamic_wind to update
949 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
951 * ports.c (current-load-port): New procedure.
953 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
955 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
956 not a tty, return #f.
958 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
959 to Julian Satchell and Roland Kaufmann.)
961 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
962 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
964 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
966 * debug.h, debug.c (scm_start_stack): New function. Implements
967 the guts of old scm_m_start_stack.
969 * debug.c (scm_m_start_stack): Use scm_start_stack.
971 * init.c (scm_start_stack, scm_restart_stack): Renamed to
972 start_stack and restart_stack. (These have static scope.)
974 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
976 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
977 readline functions to come in release 2.3. (Thanks to Chet
979 (handle_errors): Use the above functions.
981 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
983 * readline.c: Improvements for readline support: Handle errors
984 better; Implement before-read-hook.
986 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
988 * init.c (scm_boot_guile_1), readline.c: Test for
989 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
990 assure that we have version >= 2.1.)
992 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
994 * readline.c (scm_readline): Defer interrupts while we're calling
997 * readline.c (scm_add_history): Bugfix: Do strdup before giving
998 away the string to add_history.
999 (completion_function): Do completion for readline. (Thanks to
1001 (scm_filename_completion_function): New procedure: Filename
1003 (current_input_getc): New function. Use this one instead of
1004 standard getc from readline.
1006 * throw.c, throw.h (scm_handle_by_throw): New function: This
1007 handler throws errors to next handler on the dynwind chain.
1009 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1011 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1014 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1016 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1018 (scm_procedure_properties): Modified to return arity together with
1020 (scm_procedure_property): Added the read-only property `arity'.
1021 (scm_set_procedure_property_x): It is an error to set the `arity'
1024 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1025 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1027 * procprop.h (scm_sym_arity): New symbol.
1029 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1030 to set the dispatch procedure of an operator or entity object.
1032 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1033 Made procedure slots read-only.
1035 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1036 scm_tcs_cons_gloc case in zero args switch; Fixed args
1037 construction for operators in scm_tcs_cons_gloc case in two args
1040 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1042 * fluids.c: Removed use of assert.h (in order to avoid
1045 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1047 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1049 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1050 change makes the evaluator safer at the cost of evaluation speed.
1051 It handles the case when the user has added a non-immediate
1052 improper end of the application form, e.g., `(+ 0 . x)'.
1053 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1054 minimize the extra cost as much as possible. The new code is
1055 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1056 problem with structs planted directly in the code (e.g. by a
1057 macro). This no longer causes segmentation fault. (Thanks to
1060 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1061 arg `proc' in order to be able to throw errors; New argument
1064 * Removed extra #include "debug.h"
1066 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1068 * scmsigs.c: Declare usleep as returning void on some systems.
1069 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1072 * coop.c (usleep): Return void on some systems.
1074 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1076 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1078 * coop.c: Changed return type of usleep to int.
1080 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1081 isn't found in the OS.
1083 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1084 isn't enabled. (Thought that I had made this change ages ago...)
1086 * iselect.c: Declare bzero if not defined by OS.
1088 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1090 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1091 condition. (Thanks to John Tobey.)
1093 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1094 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1097 * __scm.h: Start the long-term project of moving to POSIX threads.
1098 Phase 1: Classification of all critical sections.
1099 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1100 for A sections. (See comments in __scm.h for details.)
1102 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1103 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1105 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1107 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1108 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1109 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1110 dependencies on $(srcdir)/Makefile.in
1111 $(top_builddir)/config.status in order to avoid circularity.
1113 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1114 from argc if argc was 0 initially.
1116 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1117 in generation of libpath.h.
1119 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1121 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1122 libguile from 2 to 3.
1124 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1126 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1128 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1130 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1131 scm_set_port_column_x, scm_port_filename,
1132 scm_set_port_filename_x): Removed optional arguments. Added
1133 proper argument checking.
1135 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1136 stack size in machine words.
1138 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1139 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1140 to Ole Myren Röhne.)
1142 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1144 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1145 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1147 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1150 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1151 procedure apply: Copy argument lists before pushing them unto the
1152 environment so that the environment won't get mutated due to
1153 manipulation of procedure arguments. This should perhaps be
1154 regarded as a temporary solution until someone finds a more
1155 efficient one. (Thanks to Maciej Stachowiak.)
1157 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1159 * script.c (scm_compile_shell_switches): Use "guile" as default
1160 zero arg if argc is NULL.
1162 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1164 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1165 is zero. (Thanks to Dirk Herrmann.)
1167 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1169 * ports.c (scm_add_to_port_table): First line is now line 0
1170 (was 1). (Interface changed according to suggestion by Per
1173 * backtrace.c (display_header): Add 1 to line and column numbers
1174 when presenting them to the user.
1176 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1177 from debug.c --> eval.c
1179 * eval.h, eval.c (scm_eval_options_interface): New options
1181 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1182 i.e. stacks for new threads.
1184 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1186 * eval.c (unsafe_setjmp): Removed with #if 0.
1188 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1191 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1192 to avoid compiler warnings.
1194 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1196 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1198 * throw.c (handler_message): Print message on current error port
1199 instead of default error port. (Thanks to Maciej Stachowiak.)
1201 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1203 * ports.c (scm_add_to_port_table): allocate in units of
1204 struct scm_port_table *, not struct scm_port_table.
1205 * posix.c (scm_close_pipe): remove the port from the port table
1207 Thanks to Rob Engle for both fixes.
1209 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1211 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1212 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1214 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1216 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1218 * backtrace.c (display_error_body, display_backtrace_body),
1219 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1220 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1221 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1222 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1225 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1226 don't receive the jmpbuf arg anylonger.
1227 (scm_catch): Don't accept a #f tag.
1228 (scm_throw): Check that key is a symbol.
1229 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1231 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1233 * async.c (async_pending): Removed declaration.
1235 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1237 * dynwind.c (scm_wind_chain): New debug function.
1239 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1240 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1241 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1242 extra layer of functions around the body and handler of a thread.
1243 This extra layer makes sure that the handler is called in the
1244 dynamic context of the surround (= empty dynwind list), but under
1245 the *dynamic root* of the body. We can not use the dynamic root
1246 of the surround since that root belongs to another thread => stack
1247 is not handled correctly. It may seem ugly to use this extra
1248 layer, but the extra cost in terms of execution time is really
1249 negligible compared to the total amount of time required to create
1250 a thread, and it would reduce maintainability to duplicate the
1251 crucial and complicated steps performed by cwdr.
1253 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1254 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1255 get re-enabled. The important effect of this is that interrupts
1256 are blocked during thread switching so that thread data structures
1257 don't risk getting messed up by an unfortunate signal.
1258 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1259 seems to do more aggressive optimization which actually move
1260 instructions around in these macros in a fatal way. Therefore:
1261 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1262 just superstitious...)
1263 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1264 This macro should be used instead of SCM_ASYNC_TICK since the
1265 latter doesn't do context switches any more.
1267 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1268 instead of SCM_ASYNC_TICK.
1270 * coop.c, iselect.c: Since thread switches are now performed with
1271 interrupts masked, we can't use the old mechanism of delivering
1272 signals immediately when they arrive. Signals must instead be
1273 delivered when the asyncs run *after* the end of the critical
1274 section in scm_internal_select. But this also means after context
1275 switch so that the signal will be delivered to a different thread.
1276 To avoid this, I have changed the protocol of
1277 coop_wait_for_runnable_thread and friends so that they are allowed
1278 to return the original thread. So, if a signal arrives during
1279 scm_internal_select, we won't any longer be forced do a context
1280 switch, but can remain in the same thread and deliver the signal
1283 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1284 scm_asyncs_pending and made it global.
1286 * iselect.c: Small fixes.
1288 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1289 coop_condition_variable_init, coop_condition_variable_wait,
1290 coop_condition_variable_signal): Changed return type from `void'
1291 to `int'. This is to adhere closer to the pthreads interface.
1292 This, in turn, is part of an attempt to provide C versions of the
1293 mutex and condition variable primitives which can be part of a
1294 frontend to COOP or pthreads.
1296 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1297 coop_condition_variable_destroy): New functions.
1299 * coop-threads.c (scm_wait_condition_variable): Use
1300 coop_condition_variable_wait_mutex.
1302 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1303 Definitions moved to coop-defs.h.
1305 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1306 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1307 scm_cond_destroy): New C interface to mutecis and cond vars.
1309 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1311 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1313 * iselect.c: Now several threads can wait on the same file
1314 descriptor. The behaviour is compatible with OS select: All
1315 threads waiting for the fd return with the same status.
1317 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1319 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1320 Can spawn a thread from application C code.
1322 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1324 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1325 gh_doubles2scm): New functions.
1327 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1329 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1330 commented-out version of gh_eval_str()
1332 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1334 * socket.c (scm_bind): free soka after use.
1336 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1338 * stime.c (tzvar): new variable.
1339 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1340 avoid memory leaks when allocating.
1342 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1344 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1347 * gc.c, tags.h: Doc fixes.
1349 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * eval.c (macro-eval!): Removed. This function was a design bug.
1352 It allowed memoized code to leak out to the scheme level. Most
1353 things that you could do with `macro-eval!' can be done with
1356 1997-12-20 Tim Pierce <twp@skepsis.com>
1358 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1359 scm_fgets now depends on ftell(3) to know how many bytes were
1362 1997-12-15 Tim Pierce <twp@skepsis.com>
1364 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1365 dealing with strings.
1367 1997-12-13 Tim Pierce <twp@skepsis.com>
1369 Make %read-line more suitable for implementing read-line efficiently.
1370 * ioext.c (scm_read_line): Strip the terminating newline from a
1371 string, and return a cons of the string and its terminator.
1373 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1374 of the string that is read is stored in this memory location.
1375 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1376 * genio.c, genio.h (scm_do_read_line): Update caller.
1377 * ports.h (scm_ptobfuns): Update typedef.
1378 * fports.c (scm_fptob, scm_pipob): Update struct.
1380 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1382 * filesys.c (set_element): Return file descriptor.
1383 (fill_select_type): Return the highest file descriptor.
1384 (scm_select): Tell select about the highest file descriptor. On
1385 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1386 Therefore the extra overhead for calculating the maximum fd seems
1387 to be more than compensated. Is this correct? In any case,
1388 scm_internal_select will be much faster with this info.
1389 (scm_select, fill_select_type, set_element): Don't accept any kind
1390 of object in the file descriptor list or vector.
1392 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1394 * iselect.c (finalize_fd_sets): Bugfix.
1396 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1398 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1399 when using scm_internal_select (since we might switch to another
1402 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1404 * simpos.c (scm_system): always define: use sysmissing if not
1405 available. Check for HAVE_SYSTEM instead of _Windows (does
1406 Windows lack system or does it have an unusable one?).
1407 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1408 Let the argument be optional: if not supplied, call system(NULL).
1410 * ports.c (scm_close_port): relax the type check from OPPORTP to
1411 PORTP; closing a closed port is allowed.
1413 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1415 * fports.c (scm_fgets): Return if the last char in a chunk is
1416 newline. When fgets returns a string whose length is `size-1', it
1417 is ambiguous whether a whole line was retrieved, so we must check
1418 explicitly whether a line terminator is present.
1420 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1422 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1423 before taking the CDR. (Thanks to Harald Meland.)
1425 * filesys.c (scm_stat): Slightly optimized.
1427 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1429 * ports.c (scm_close_port): Make sure the port is open before
1432 * guile-snarf.in: Pass args through to gcc in a way that preserves
1433 whitespace boundaries. (Thanks to Greg Badros.)
1435 1997-12-02 Tim Pierce <twp@skepsis.com>
1437 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1438 statement. (Thanks to Doug Evans for pointing this out.)
1440 1997-12-01 Tim Pierce <twp@skepsis.com>
1442 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1444 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1446 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1447 errno macro expansion of this field name. (errno is a C
1448 preprocessor macro on some systems.)
1450 1997-11-29 Tim Pierce <twp@skepsis.com>
1452 * iselect.c: Doc fix.
1454 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1456 * init.c (scm_start_stack): Removed initialization of
1457 scm_the_last_stack_var.
1459 * backtrace.h: Declare scm_the_last_stack_var.
1461 * backtrace.c: Define scm_the_last_stack_var.
1463 * root.c (mark_root): Don't mark the_last_stack_var.
1465 * root.h (scm_root_state): Removed the_last_stack_var.
1467 * throw.c: Added #include "fluids.h"
1468 (ss_handler): `the-last-stack' is now a fluid.
1470 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1471 --> the_last_stack_fluid.
1473 * backtrace.c: Added #include "fluids.h"
1474 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1475 (scm_backtrace): `the-last-stack' is now a fluid.
1477 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1478 after scm_init_fluids.
1480 1997-11-28 Tim Pierce <twp@skepsis.com>
1482 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1484 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1485 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1487 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1489 * iselect.c (coop_next_runnable_thread,
1490 coop_wait_for_runnable_thread): Disable interrupts so that no
1491 async is executed before a potential error_revive.
1492 (scm_internal_select): Disable interrupts during the parts of the
1493 code which manipulate the sleep queue and the file descriptors.
1495 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1497 * Makefile.am: Added iselect.c and iselect.h.
1499 * coop.c (coop_qinit): Initialize fields used by
1500 scm_internal_select.
1501 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1502 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1503 replacement in iselect.c.
1504 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1505 coop_join): If GUILE_ISELECT enabled, use
1506 coop_wait_for_runnable_thread instead of
1507 coop_next_runnable_thread.
1508 (usleep, sleep): New replacements for system functions if
1509 GUILE_ISELECT is enabled.
1511 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1513 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1515 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1516 iselect.h. Implement Scheme level `select' using
1517 scm_internal_select. (See NEWS.)
1519 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1521 * init.c: Call scm_init_iselect.
1523 * iselect.h, iselect.c: New files. Implements
1524 scm_internal_select. (See NEWS.)
1526 1997-11-27 Tim Pierce <twp@skepsis.com>
1528 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1529 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1530 and scm_must_free, since ultimately the string returned will be copied
1531 by scm_makfrom0str anyway. Also, read any characters that may have
1532 been pushed onto the port with scm_ungetc.
1533 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1534 * ioext.c (scm_read_line): Free string after Guilifying it.
1535 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

1539 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1541 * gh.h: Safely wrap prototypes for c++ usage.
1543 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1545 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1546 gh_repl (argc, argv).
1548 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1550 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1551 and to invoke scm_shell().
1552 (gh_launch_pad): took out the loading of boot-9.scm from here,
1553 since it is probably best to let the user control that. In fact,
1554 gh_repl() now invokes scm_shell() which does that.
1556 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1558 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1561 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

1564 yesterday's underscore patch. (Thanks to Marius Vollmer for
1567 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1569 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if

1575 (gh_uniform_vector_ref): started implementing the uniform types in
1578 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1580 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1581 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1583 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1585 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1586 configure.in was changed).
1588 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1590 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1591 * Makefile.in: Regenerated.
1593 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1595 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1596 OPORT is an `open' port, not an output port.
1598 * filesys.c (scm_close, set_element, get_element, scm_chown,
1599 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1600 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1601 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1602 scm_close_port, scm_port_line, scm_set_port_line_x,
1603 scm_port_column, scm_set_port_column_x, scm_port_filename,
1604 scm_set_port_filename_x, scm_port_mode,
1605 scm_close_all_ports_except, scm_set_current_output_port,
1606 scm_set_current_error_port): Likewise
1607 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1608 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1610 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1611 * backtrace.c (display_backtrace_body): Likewise
1612 * fports (scm_setvbuf): Likewise
1613 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1614 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,

1616 * unif.c (scm_uniform_array_write): Likewise
1618 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1620 Minor problems with substring-related tag changes.
1621 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1622 exactly what we want to leave in to detect substrings.
1623 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1624 * tags.h: Fix diagrams and comments describing the S tag bit;
1625 remove vestigial remarks about the D tag bit.
1626 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1627 * strings.c: Formatting tweaks.
1629 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1630 variable first; then SCHEME_LOAD_PATH, with a warning message.
1631 (scm_parse_path): New function.
1632 * script.c: Doc fixes.
1634 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1636 Readline support, from Daniel Risacher.
1637 * readline.c, readline.h: New files.
1638 * init.c: #include "readline.h".
1639 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1640 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1641 * Makefile.in: Regenerated.
1642 * scmconfig.h.in: Regenerated, after change to ../configure.
1644 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1646 * gh.h: gh_vector_set -> gh_vector_set_x
1648 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1650 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1651 with the ! -> _x mapping when going from Scheme to C.
1653 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1655 * gh.h (gh_reverse):
1663 (gh_assoc): added these gh_ functions implemented as macros.
1665 * gh_predicates.c (gh_null_p):
1666 (gh_string_equal_p): added these two missing predicates.
1668 * gh_list.c (gh_append):
1673 (gh_set_cdr_x): added these routines as I go through and try to
1674 complete the picture R4RS functions that should be mirrored in the
1677 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1679 * tags.h (scm_tc7_substring): Changed the comment and code to
1680 conform with the changes below. Folks! We have suddenly two new
1681 free tc7 codes!!! Jummy, jummy!
1683 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1685 * Makefile.in: Rebuilt.
1686 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1688 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.

1704 * tags.h (SCM_TYP7SD): Removed.
1705 (SCM_TYP7D): Removed.
1706 (scm_tc7_mb_string): Removed.
1707 (scm_tc7_mb_substring): Removed.
1708 * print.c (scm_iprin1): Handle char printing directly. Don't
1710 Don't include "mbstrings.h".
1711 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1712 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1714 Don't include "mbstrings.h".
1715 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1716 (SCM_SYMBOL_SLOTS): Define as 4.
1717 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1718 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1719 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1720 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1721 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1738 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1739 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1741 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1743 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1745 * gh_test_c.c (c_vector_test): some improvements on the vector
1748 * gh.h (gh_vector): this used to exist but do the wrong thing.
1749 Now it (almost) does the right thing, though it takes a list
1750 instead of the individual arguments. I need to see how it could
1752 (gh_list_to_vector): added this function as a macro. Corresponds
1753 to Scheme's (list->vector ...).
1754 (gh_vector_to_list): added this function as a macro. Corresponds
1755 to Scheme's (vector->list ...).
1757 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1758 gh_vector_ref, so that it resembles the Scheme routines more.
1759 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1760 resembles the Scheme routines more.
1761 (gh_make_vector): this used to be (stupidly) called gh_vector().
1762 This is the right name, since it does the same thing as the Scheme
1763 (make-vector ...) procedure.
1765 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1767 * ports.h: #include "libguile/print.h"
1769 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1770 Some indentation fixes.
1772 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1773 longer a user field; New field: class_flags.
1775 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1777 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1779 * gh_data.c (gh_bool2scm): new function which replaces
1780 gh_int2scmb(), which is now tagged as obsolete.
1782 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1784 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1785 macros should by convention not test for NIMPness.)
1786 (SCM_COERCE_OPORT): Adjust indentation.
1788 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1789 SCM_NIMP test before SCM_PRINT_STATE_P.
1791 * struct.c, struct.h, gc.c: Renamed:
1792 scm_struct_i_layout --> scm_vtable_index_layout
1793 scm_struct_i_vcell --> scm_vtable_index_vcell
1794 scm_struct_i_vtable --> scm_vtable_index_vtable
1795 scm_struct_i_printer --> scm_vtable_index_printer
1796 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1798 * struct.c (scm_print_struct): Use new printer slot; Default
1799 printing: Also output hex code of vtable so that type identity
1800 will be indicated as well.
1801 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1802 Removed struct_printer_var; Removed struct-vtable-offset;
1803 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1804 vtable-offset-user): New constants.
1806 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1807 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1808 If this slot contains a procedure, use that to print structures of
1809 the type represented by this vtable.
1811 * print.c (scm_iprin1): Don't print arguments of macro
1812 transformers. (They are always: exp env.); Bugfix: Unmemoize
1813 transformer source with correct environment.
1815 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1817 Streamlining of call-with-dynamic-root:
1819 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1820 there is now only one catch.
1821 (cwdr_outer_body): Removed.
1822 (cwdr_handler): New function.
1823 (scm_internal_cwdr): New function to perform the function of cwdr
1824 but take args that are more useful to C code. Also, the handler
1825 is now invoked *outside* of the new dynamic root, like the docs
1826 say. We no longer have to catch absolutely all errors, the caller
1827 is responsible for using a handler that does not throw, if he
1829 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1830 * root.h (scm_internal_cwdr): New prototype.
1832 Even more but risky streamlining:
1834 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1835 allocation of the jumpbuf of a root continuation. The changes
1836 below are controlled by it. They are now deactivated.
1837 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1838 the JMPBUF of the scm_rootcont to NULL before returning.
1840 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1841 when they are non-NULL.
1842 (scm_gc_mark): Likewise, mark only when non-NULL.
1844 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1845 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1847 * gc.c (scm_done_malloc): New function.
1848 gc.h (scm_done_malloc): New prototype.
1850 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1851 (struct scm_print_state) [revealed]: New field.

1853 type checking purposes.
1854 (scm_valid_oport_value_p): New prototype.
1856 * print.c (scm_valid_oport_value_p): New function to check whether
1857 a certain value is acceptable as a port argument.
1858 (scm_print_state_vtable): New variable.
1859 (scm_free_print_state): Set `revealed' field to false.
1860 (scm_iprin1): Call user supplied closure printer with
1861 scm_printer_apply. Print in the traditional way when there isn't
1862 one or when it returns #f.
1863 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1864 Accept a port/print-state pair in addition to just a port.
1865 (scm_prin1): Don't return the print_state to the pool when it has
1867 (scm_printer_apply): Set `revealed' field of print_state to true.
1868 (scm_init_print): Set scm_print_state_vtable.
1869 (print_state_fluid, print_state_fluid_num): Removed.
1871 * throw.h (scm_handle_by_proc_catching_all): New prototype
1872 throw.c (scm_handle_by_proc_catching_all): New function
1874 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1876 * Makefile.in: Regenerated with automake 1.2c.
1878 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1880 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1881 was looping endlessly.
1883 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1885 * strports.c (scm_eval_string): Don't close the port.
1887 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1888 former returns a nice normal integer. (Thanks to Daniel
1891 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1893 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1894 makefile variable as a build parameter called LIBS. The
1895 build-guile program will use this, for the time being.
1896 * Makefile.in: Regenerated.
1898 Thanks to Shiro Kawai:
1899 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1900 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1903 * Makefile.in: Regenerated with automake 1.2a.
1905 * script.c (scm_compile_shell_switches): If we hit the -c or --
1906 arguments, don't set the car of (command-line) to scm_usage_name,
1907 the prettified name of the guile executable; give it the full
1908 path, the way shells usually handle $0.
1910 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1912 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1913 Scheme-level name `array-map' and renamed `serial-array-map' to
1914 `serial-array-map!'.
1916 * backtrace.c: Introduced exception handlers which now enclose
1917 `display-error' and `display-backtrace' so that error reporting
1918 won't get into infinite loops if an error occurs during displaying
1919 of the error. This can very easily happen with user supplied
1920 print call-back routines.
1922 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1924 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1925 the names `serial-array-map' and `array-map' should be removed.)
1927 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1929 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1930 Added #include "objects.h"
1932 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1933 Add #include "feature.h".
1935 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1936 (modinclude_HEADERS): Added objects.h.
1938 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1939 This test is needed at many places in the code and should be
1940 abstracted. (Motivated by the need of this test in libguiletk.)
1942 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1943 (scm_eval_string), load.c (scm_primitive_load,
1944 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1945 Use SCM_EOF_OBJECT_P.
1947 * eval.c (scm_init_eval): Add feature `delay'.
1949 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1951 * scmhob.h: Removed.
1953 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1955 * list.h (SCM_LISTn): New macros. Make list creation in C code
1956 prettier. The idea comes from STk.
1958 * sequences.h, sequences.c, append.h, append.c: Removed. These
1959 files implemented non-R4RS operations which would encourage
1960 non-portable programming style and less easy-to-read code.
1962 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1965 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1966 sequences.h, #include append.h.
1968 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1971 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1973 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1975 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1977 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1979 * eval.c: Added #include "objects.h"
1981 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1984 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1985 adjacent smob numbers.
1987 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1989 * procprop.h: Added declaration of scm_i_inner_name.
1991 * gsubr.c: New global symbol scm_i_inner_name.
1993 * debug.c (scm_procedure_name): Try procedure property
1994 `inner-name' if `name' fails.
1996 * print.c (scm_iprin1): Use scm_macro_name.
1998 * eval.c (scm_m_define): Give names to macros as well; Only the
1999 first top-level definition gives a procedure/macro a name.
2000 Otherwise confusing names can turn up in backtraces.
2001 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2002 `name'; Give names to macros as well.
2004 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2005 (scm_macro_transformer): Use SCM_CLOSUREP instead of

2010 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2012 (prinmacro): Removed. The code has been moved/merged into print.c
2013 in order to decrease code redundancy. We want macros to print in
2014 a way equivalent to procedures, and it would be silly to duplicate
2015 the required code. (We don't want to maintain two places.)
2016 (macrosmob): Print field is now a NULL pointer.
2018 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2019 scm_macro_transformer): New prototypes.
2020 (scm_tc16_macro): Declared.
2022 * print.c (scm_iprin1): Added code for printing of macros. Macros
2023 are now printed in a way equivalent to procedures.
2025 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2027 * procs.h (scm_closure_p): Added declaration.
2029 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2031 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2032 Shouldn't pass "heap" as the subr name.
2034 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2036 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2037 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2038 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2039 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2040 SCM_BOOL_T. Any non-false value is true.
2042 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2044 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2045 scm_gensym): Added prototypes.
2047 * symbols.c (scm_gensym): New function. This will speed up
2048 certain types of applications (such as macro systems) which
2049 generate lots of symbols.
2051 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2053 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2055 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2057 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2058 specifier, since (2) or (2 . 3) would cause SEGV.
2059 (scm_transpose_array): more argument checking fixes.
2061 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2063 * Makefile.in: Regenerated.
2065 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2067 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2069 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2071 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2073 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2075 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2076 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2079 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2080 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2081 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2082 scm_array_p, scm_array_rank, scm_array_dimensions,
2083 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2084 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2085 scm_array_prototype): Added case scm_tc7_wvect.
2087 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2089 * errno.h: prototype for scm_strerror.
2090 * error.c (scm_strerror): new procedure.
2092 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2094 * list.c (scm_list_append_x): Allow non-pair as last argument.
2095 This is consistent with the R4RS append and is probably the
2096 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2098 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2100 * stime.h: prototype for scm_times.
2101 * stime.c (scm_times): new procedure.

2118 third argument is now optional.
2120 * posix.c (scm_execl, scm_execlp): make the filename argument
2121 compulsory, since omitting it causes SEGV.
2122 (scm_sync): return unspecified instead of #f.
2123 (scm_execle): new procedure.
2124 (environ_list_to_c): new procedure.
2125 (scm_environ): use environ_list_to_c. disable interrupts.
2126 (scm_convert_exec_args): take pos and subr arguments and
2127 improve error checking.
2129 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2131 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2132 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2133 argument to SCM_ASSERT. Furthermore, the name of the function
2134 should be passed as first argument when signalling
2135 SCM_WNA. (Thanks to Thomas Morgan)
2137 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2138 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2139 dispatches on the number of actual args has a default case
2140 reporting an internal error. This is a vestige from a version
2141 that mallocated a SCM vector to hold the arguments. In the
2142 current version this check is too late: if it ever happens we will
2143 have already overstepped the bounds of the array.
2145 Also, the patch [...] adds a check for too many actual arguments."
2147 mdj: Removed check for "internal programming error".
2149 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2151 * gh_io.c (gh_write): New function.
2153 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2154 throw.c (scm_internal_stack_catch): New sibling to the other catch
2155 functions. Code moved from gh_eval.c.
2156 throw.h: Added header.
2157 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2158 scm_internal_stack_catch.

2164 Scheme name is now dup->fdes.
2165 (scm_dup_to_fdes): make the second argument optional and
2166 fold in the functionality of scm_primitive_dup.
2167 (scm_primitive_dup): deleted.
2169 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2171 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2172 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2173 ultrix are defined. Use setvbuf instead of setbuf.
2174 (scm_setvbuf): new procedure.
2175 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2176 (scm_setfileno): moved from ioext.c.

2188 state as nested data while they are printed.
2189 (print_state_fluid, print_state_fluid_num): New variables.
2190 (scm_init_print): Initialize them.
2191 (scm_iprin): If print_state_fluid carries a print_state, use that
2192 instead of creating a new one.
2193 (scm_printer_apply, apply_stub, struct apply_data): New
2194 definitions to help with calling printer functions written in
2196 * print.h (scm_printer_apply): New prototype.

2209 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2210 SCM_ASSERT: arg comes before pos.
2212 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2214 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2215 to a list of length zero correctly.
2217 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2233 * ioext.h: removed scm_duplicate_port prototype.
2235 * ioext.c (scm_primitive_dup2): return the new file descriptor
2236 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2238 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2239 stream has been set.
2240 (scm_duplicate_port): deleted, there's now an implementation in
2242 (scm_primitive_dup2): do nothing if newfd == oldfd.
2244 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

2255 * ports.h: prototypes too.
2256 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2258 * fports.h: prototype too.
2259 * fports.c (scm_evict_ports): moved from ioext.c.
2261 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2266 * filesys.h: scm_close prototype.
2267 * filesys.c (scm_close): new procedure, can close file descriptors
2268 and ports (scsh compatible).
2270 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

2292 * dynl.c (free_dynl_obj): New function to free the dynamic object
2293 data. (dynl_smob): Use it.
2294 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2295 the dynamic object data below the linking of the object to avoid
2296 memory leak when the linking code throws an error. Now the code
2297 leaks a whole dynamically linked library when must_malloc throws,
2298 but that should be much less likely.
2300 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2302 Changes to compile under gnu-win32, from Marcus Daniels:

2342 * read.c (recsexpr): Give this a dummy definition if
2343 DEBUG_EXTENSIONS isn't #defined.
2345 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2347 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2358 alloca.lo will be included in @LIBLOBJS@. Something better than
2359 this should be possible.
2360 * Makefile.in: Regenerated.
2362 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>

2372 have to do this explicitly. Also, if regexp/basic is supplied, then
2373 turn off REG_EXTENDED.
2374 (scm_init_regex_posix): New regexp/basic symbol.
2375 (REG_BASIC): #define this if it is not already present.

2398 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2400 (scm_init_regex_posix): Define constants for the REG_mumble flags;

2418 * root.c: Establish a reliable catch-all handler for the new root.
2419 After all the Scheme handler function might signal an error too,
2420 and we don't want to lose that.

2422 (cwdr_outer_body): New function, to establish the user's handler,
2423 and pass control to cwdr_inner_body.

2435 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2436 the feeling that real thread systems will not need this...
2438 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2440 Try to detect when people are using one version of libguile and a

2452 primitive definitions under their Scheme names.
2454 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2455 1:2. Helps avoid confusion between installed and uninstalled libs.
2457 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2460 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2461 backslash from definition; this should be used like: GDB_INTERFACE;
2463 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2465 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2466 new port unbuffered until its stream has been set.
2468 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2470 * ports.h: new prototype.
2471 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2473 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2475 Make things compile neatly under Sun's C compiler.
2476 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2477 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2478 unsigned, because that's what the ANSI function takes.
2479 * extchrs.h (xmbtowc): Corresponding change to prototype.
2480 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2482 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2483 argument plain char *.
2484 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2486 * tag.c (scm_tag): Remove unreachable statement.
2487 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2488 top of the word, it should be unsigned.
2490 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2491 is defined, to avoid warnings; it's only used in the
2492 conflict-checking code. Which might go away anyway.
2493 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2494 conditionals; put the label definition in an #if too, to stifle
2497 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2498 ChangeLog-threads in the distribution.
2499 * Makefile.in: Regenerated.
2501 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2503 * guile-snarf.in: Changed regexp to support CPPs that insert
2504 whitespace between lexical tokens (which munges the `%%%' snarf
2507 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2509 * load.c (scm_init_load_path): Append $(datadir)/guile to
2510 %load-path, so modules do not have to be installed in Guile's
2511 current version directory.
2513 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2515 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2516 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2517 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2518 call the sysdep functions with deferred ints.
2519 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2520 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2521 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2524 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2527 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2529 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2531 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2533 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2536 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2538 * eval.c (scm_lookupcar1): New procedure to cope with a race
2539 condition during lookup (when using threads).
2540 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2541 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2544 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2546 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2547 supplied. (Change from Tim Pierce.)
2549 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2551 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2552 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2553 default and not `()'. `#f' is the canonical non-value in Scheme,
2556 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2558 * struct.c (struct_printer): New variable that holds a handle on
2559 the Scheme variable *struct-printer*. This variable can be set by
2560 Scheme code to override the printing of structures.
2561 (scm_print_struct): If struct_printer is set, call it. If it is
2562 not set, or returns #f, print the structure in the old fashion.
2563 Include "eval.h" for scm_apply.
2565 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2567 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2568 scm_struct_i_n_words to get the number of fields, not
2569 -scm_struct_n_extra_words.
2571 On the route to fancier struct printing:
2572 * struct.c (scm_print_struct): New function to print a structure.
2573 Include "genio.h" to support it. This function doesn't do
2574 anything interesting right now, but I think it should be here
2576 * struct.h: Include "print.h" and add prototype for
2578 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2579 print structures ourself.
2581 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2583 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2584 before applying the handler in case it doesn't return.
2586 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2588 * scmsigs.h, async.h: updated.
2590 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2593 * posix.c (scm_uname): interpret only negative values as an error.
2594 Solaris normally returns a positive value.
2596 * script.c (scm_compile_shell_switches): if we are not going into
2597 an interactive repl, set scm_mask_ints to zero so that asyncs can
2600 * simpos.c (scm_system): don't ignore/unignore signals around
2603 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2606 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2607 done in boot-9.scm instead.
2609 * scmsigs.c, async.c: Major rewriting of signal handling code.
2610 (scm_sigaction): new procedure.
2611 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2613 (scm_raise): return unspecified, throw error on failure.
2615 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2617 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2618 feature, to help boot-9.scm decide whether to import the regex
2621 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2623 * eval.c: Include scmconfig.h at the beginning of the file so that
2624 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2627 * regex-posix.c: #include "_scm.h" before conditionally #including
2628 <regex.h>; the former defines HAVE_REGCOMP.
2630 * regex-posix.c: #include <regex.h> conditionally, so the file is
2631 CPP'able (for dependency scanning) even on systems that don't have
2634 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2636 Add new R4RS-compliant syntax for keywords.
2637 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2638 regardless of the setting of the `keywords' read option.
2639 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2640 can be re-read no matter what the setting of the `keywords' read
2643 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2645 Add support for POSIX regular expressions.
2647 * regex-posix.c, regex-posix.h: New files. (Some code
2648 is taken liberally from rx/rgx.c in the old Guile dist.)
2650 * init.c: Include regex-posix.h.
2651 (scm_boot_guile_1): Call scm_init_regex_posix.
2653 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2654 Add regex-posix.[ch] sources.
2655 * Makefile.in: Regenerated.
2657 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2658 to do this automatically? It didn't for me, bleh.)
2660 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2662 * fports.c (print_pipe_port): New function.
2663 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2664 latter doesn't even take the right arguments.
2666 * Makefile.am: Increment shared lib revision number. I think
2667 sometimes the uninstalled Guile finds the installed shared lib;
2668 Gord says doing this might help. As things turned out, I can't
2669 say whether it does.
2670 * Makefile.in: Regenerated.
2672 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2673 passing it as the closure argument to scm_boot_guile. (Bill
2676 * ports.c (print_void_port, putc_void_port, puts_void_port,
2677 write_void_port, flush_void_port, getc_void_port, close_void_port,
2678 noop0): Use ANSI prototypes instead of K&R declarations, so the
2679 initialization of void_port_ptob gets aggressively type-checked.
2680 Fix arguments of print_void_port and write_void_port. (Bill

2714 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2716 * script.c (scm_find_executable): Use prototype-style definition
2717 here; apparently it's not quite right to have const in a prototype
2718 and then use a K&R declaration. I wonder if stuff like this will
2719 go away if we compile with -Wrequire-prototypes, or whatever that
2720 is... (Bernard URBAN)
2722 * scmhob.h: New text from Bernard URBAN.
2724 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2726 * script.c: Don't #define const on hpux. Configure takes care of
2727 this. (Thanks to Larry Schwimmer.)
2729 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2730 decide whether to #include <unistd.h>, instead of listing a bunch
2731 of systems. Don't #include stdio twice. Removed dyked-out
2732 definition of scm_find_impl_file.
2734 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2736 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2737 library version info to 1:0.
2738 * Makefile.in: Regenerated.

2744 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2745 throw.c: Update copyright years; these files have been worked on
2746 significantly in 1997, but only had copyright years for 1996.
2747 Also, change name of copyright holder on some from Mikael
2748 Djurfeldt to Free Software Foundation; he has signed papers
2749 assigning the changes to the FSF.
2751 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2752 reason not to give the user the option.
2754 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2755 Return #f on end-of-file when scanning table (i.e. when called
2756 with no arguments). Try to catch errors, when we can.
2757 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2759 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2760 external declarations. These are useful.
2762 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2764 * posix.c: don't include <sys/select.h> or define macros for
2765 select, since they were not used in this file.
2767 * filesys.c (scm_select): make the fifth parameter microseconds,
2768 not milliseconds. let the fourth parameter be either a real value
2769 or an integer or #f. The first, second and third arguments can
2770 now be vectors: the type of the corresponding return set will be
2772 (set_element, get_element): new static procedures.
2774 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2776 * strports.c (scm_eval_string): New function.
2777 (scm_eval_0str): Trivially re-implemented in terms of
2779 * strports.h (scm_eval_string): New extern decl.
2781 * net_db.c (h_errno): Add extern decl for this.
2783 * fports.c (local_pclose): New function.
2784 (scm_pipob): Use it in the initializer here.
2787 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2788 Use a meaningful error message when signalling an error. For
2789 this, scm_gethost must check h_errno rather than errno.
2791 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2793 * Makefile.in: Regenerated, using automake-1.1p.
2795 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2797 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2798 not SCM_UNSPECIFIED.
2800 * script.c (scm_compile_shell_switches): don't append (quit) if
2802 (scm_shell): call scm_exit_status and exit on the result of the
2805 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2807 Ensure that shared substrings are handled properly when passed to
2808 a system call or other foreign function. Many thanks to Tim
2810 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2811 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2812 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2813 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2825 SCM_COERCE_SUBSTR to make sure shared substrings are
2828 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2830 * error.c (scm_error): Add newline to error message.
2832 * init.c (scm_init_standard_ports): Doc fix.
2834 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2836 * dynl-shl.c: Completely replaced with new code from Bernard
2839 * script.c (scm_ice_9_already_loaded): New variable.
2840 (scm_compile_shell_switches): Use it.
2842 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2844 * filesys.c (scm_input_waiting_p): add missing third argument to

2848 calling gmtime in case they share a buffer.
2849 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2852 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2854 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2856 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2858 * Makefile.am (check-local): New target, which causes 'make check'
2859 to run gh_test_c and gh_test_repl, with some trivial input.
2860 * Makefile.in: Rgnrtd.
2862 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2864 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2867 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2869 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2870 sure how this was supposed to work.
2871 (scm_async_click): don't send SCM_TICK_SIGNAL.
2872 (scm_init_async): don't initialize %tick-thunk.
2874 * the following change doesn't affect the Scheme interface:
2875 gc-thunk is called at the end of garbage collection. however it's
2876 no longer implemented by pretending it's a signal.
2878 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2879 system async corresponding to scm_gc_thunk.
2880 * async.h: declare scm_gc_async.
2881 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2882 gc-thunk directly, instead of going through a signal handler.
2883 (scm_gc_async): new variable, points to the GC system-async.
2884 (scm_init_async): save the GC async as scm_gc_async instead
2885 of using system_signal_asyncs.
2886 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2888 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

2891 Don't screw up if we're interrupted.
2892 * Makefile.in: Regeneradet.
2894 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2896 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2898 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2899 we're not using AM_INIT_GUILE_MODULE any more.
2900 * Makefile.in: Reneregated.
2902 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2904 Functions for finding variable bindings, grace à Tim Pierce.
2905 * gh_data.c (gh_lookup, gh_module_lookup): New functions.

2908 Get 'make dist' to work again.
2909 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2910 * Makefile.in: Regenerated, like a surry without a fringe on top.
2912 Changes for reduced Guile distribution: one configure script,
2914 * configure.in, configure: Removed.
2915 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2916 real configure script lives.
2917 * Makefile.in, scmconfig.h.in: Regenerated.
2919 * init.c: #include "script.h", to get prototype for script.c's
2922 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2924 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2925 scm_must_malloc, not raw malloc.
2927 * script.c (scm_compile_shell_switches): Dyke out debugging output
2930 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2932 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2934 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2935 system has them. Hope this is safe. Previously
2936 sys/timeb.h was included if HAVE_FTIME was defined or if
2937 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2938 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2940 * ioext.c (scm_setfileno): add missing third argument to
2941 scm_misc_error call.
2943 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2945 * eq.c (scm_equal_p): Correctly compare strings of different
2946 varieties. (Thanks to Tim Pierce.)
2948 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2950 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2951 #! block comment must occur on a line all by itself.
2953 Move most of the guts of shell command processing into libguile,
2954 so guile.c can be very small (and eventuallly auto-generated. (I
2955 mean, generated mechanically, not self-generated. Hmm.))
2956 * guile.c, script.c, script.h: New source files.
2957 * init.c (scm_boot_guile_1): Call scm_init_script.
2958 * libguile.h: #include "script.h".
2959 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2960 targets, for new executable.
2961 (libguile_la_SOURCES): Mention script.c.
2962 (modinclude_HEADERS): Add script.h.
2963 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2964 not dynamic linking is enabled. This is because we're generating
2965 executables now. Move CY_AC_WITH_THREADS call after those, so the
2966 values of cy_cv_threads_libs captures the libs chosen above.
2967 * Makefile.in, configure, aclocal.m4: Regenerated.
2969 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2970 We don't maintain this interface any more, and it just confuses
2973 * alloca.c: #include <scmconfig.h>, not <config.h>.
2974 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2975 it'll get included in disties.
2977 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2979 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2980 be distributed, because they confuse people.
2981 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2983 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2985 * configure.in: check for presence of gethostent (not present on
2986 OpenBSD by default).
2987 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2988 * configure, scmconfig.h.in: Regenerated.
2990 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2992 * backtrace.c (scm_backtrace): Split message string across
2993 newlines properly. GCC is more tolerant of this than other
2996 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2998 Merge threads directory into libguile.
2999 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3000 threads.h: New source files.

3002 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3004 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3005 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3006 coop-threads.c.cygnus, coop-threads.h.cygnus.
3007 * configure.in: If we're using threads, include threads.o in
3009 * _scm.h, libguile.h: threads.h lives in this directory now.
3010 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3011 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3012 currently used, but brought along for information's sake.
3013 * ChangeLog-threads: log from old 'threads' directory.
3014 * Makefile.in, configure: Rebuilt.
3016 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3018 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3021 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3023 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3025 Merge GH interface library into libguile.
3026 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3027 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3028 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3029 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3031 (EXTRA_libguile_la_SOURCES): ... here.
3032 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3033 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3034 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3035 New variables, describing how to build the gh test programs.
3036 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3037 build the test programs, and we probably should have been linking
3038 libguile.la against them all along, to support AIX shared libs.
3039 Add cflags for threads to CFLAGS; add libs for threads to new
3040 variable THREAD_LIBS, used in Makefile.am.
3041 * ChangeLog-gh: log from old `gh' subdirectory.
3042 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3044 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3046 * acconfig.h: Undo change of Apr 9; including the definition of
3047 PACKAGE in the guile headers conflicts with applications' own
3049 * scmconfig.h.in: Regenerated.
3051 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3060 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3062 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3063 have S_IFSOCK. This is the case under Ultrix.
3065 * posix.c (scm_status_exit_val, scm_status_exit_val,
3066 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3067 Ultrix versions of WIFSTOPPED, etc., which assume that their
3068 arguments are lvalues (hmm).
3070 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3072 * eval.c: Doc fixes.
3074 * throw.c: Doc fixes; rearranged.
3076 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

3080 * acconfig.h: Added entry for PACKAGE.
3081 * scmconfig.h.in: Regenerated.
3083 Changes to work with automake-1.1n, which has better libtool support.
3084 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3085 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3087 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3089 * Makefile.in: Rebuild.
3091 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3093 * stime.c (scm_mktime): take an optional zone argument.
3094 (scm_localtime): check putenv return value.
3095 (scm_strftime, scm_strptime): moved from posix.c. move #include
3097 stime.h, posix.h: update prototypes.
3098 (bdtime2c, setzone, restorezone): new static procedures.
3099 (scm_mktime, scm_strftime): use them.
3100 (scm_strftime): don't call mktime before strftime. Use
3101 filltime for return value.
3102 (filltime): convert NULL zname to #f.
3103 (scm_strptime): return a count of characters consumed, not
3104 the remaining string.
3106 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3108 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3109 (scm_mktime): likewise.
3111 Uncomment localtime and mktime.
3113 * configure.in: add AC_STRUCT_TIMEZONE.
3115 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3117 * stime.c (scm_init_stime): don't define ticks/sec.
3118 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3119 return value problem and is still portable.)
3121 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3123 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3124 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3125 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3126 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3127 cpp_err_symbols.c): Corresponding changes.
3128 * Makefile.in: Regenerated.
3130 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3132 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3133 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3134 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3135 * putenv.c: new file, from sh-utils 1.12.
3137 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3138 since allocation isn't for Scheme objects.
3139 (scm_putenv): copy strings before placing in the environment.
3141 * stime.c (scm_current_time): throw an error if time returns -1,
3142 instead of returning #f.
3143 (scm_get_internal_real_time, scm_get_internal_real_time): use
3144 scm_long2num for return value instead of SCM_MAKINUM.
3146 * stime.h: prototypes updated.
3148 * stime.c (scm_time_in_msec): apparently unused, deleted.
3150 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3152 * configure.in: check for gettimeofday.
3154 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3155 which may be more usefully portable than a gettimeofday interface.
3157 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3159 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

3163 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3165 * stime.c (filltime): recovered static procedure.
3166 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

3170 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3172 * posix.c (scm_mknod): split the mode argument into type and perms
3173 arguments, like the extra fields returned by stat.
3175 * fports.c (scm_pipob): set the close, free and print procedures.
3176 (scm_close_pipe): new procedure.
3178 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3179 define them in boot-9.scm
3181 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3183 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3184 wan't defined. Don't include fd.h.
3186 * Previously fd.h was regenerated whenever configure was run,
3187 forcing a couple of files to be recompiled.
3189 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3190 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3191 Check for _fileno as well as _file.
3193 * ioext.c: don't fd.h.
3194 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3197 * Change the stratigy for getting information about errno
3198 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3199 generating lists of symbols during the build process, which will
3200 not always work, include comprehensive lists in the distribution.
3201 To help keep the lists up to date, the "check_signals" and
3202 "check_errnos" make targets can be used.
3204 * configure.in: don't check for a command to extract errno codes.
3205 * Makefile.am: update file lists, remove errnos.list and errnos.c
3206 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3207 check_errnos targets.
3208 (CLEANFILES): remove errnos.c and errnos.list, add
3209 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3210 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3211 * errnos.default: deleted.
3212 * cpp_signal.c: new file.
3213 * cpp_errno.c: renamed from errnos_get.c.
3214 * cpp_err_symbols, cpp_sig_symbols: new files.
3215 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3216 * error.c (scm_init_error): #include cpp_err_symbols instead of
3218 * posix.c (scm_init_posix): don't intern signal symbols. #include
3221 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3223 * strop.c (scm_i_index): allow the lower bound to be equal to the
3224 length of the string, so a null string doesn't always give an error.
3226 * posix.h: new prototypes.
3227 * posix.c (scm_status_exit_val, scm_status_term_sig,
3228 scm_status_stop_sig): new functions, as in scsh. They break down
3229 process status values as returned by waitpid.
3231 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3233 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3234 configure doesn't know about it.
3236 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3238 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3240 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3241 which defines C variables with global linkage.
3243 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3245 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3248 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3250 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3251 has time to check why this doesn't work well with continuations.
3253 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3255 * Fix shell syntax error; some shells won't tolerate
3256 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3258 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3260 * posix.c (scm_uname): throw an error if uname fails instead
3263 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

3272 * acconfig.h: Removed PACKAGE.
3274 * scmconfig.h.in: Regenerated.
3276 * snarf.h: g++ says it's non-portable not to specify the first
3277 argument in a varargs declaration. I introduced the first
3278 argument by using preprocessor conditionals.
3280 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3282 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

3297 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3300 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3302 support for byte vectors.
3304 * print.c (scm_iprin1): Limit number of vector elements printed
3305 according to pstate->length.
3307 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3312 * error.h: prototype for scm_error_scm.
3314 * error.c (scm_error_scm): new procedure, reimplements scm-error
3315 in C and uses scm_error.
3317 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3319 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3320 pointer to the Scheme variable read-hash-procedures and intern it
3321 in scm_init_read. Modify scm_read_hash_extend and
3322 scm_get_hash_procedure to use the pointer.
3324 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3326 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3327 (SCM_KEYWORD_STYLE): defined.
3329 * read.c (scm_read_opts): add a keywords option. This isn't a
3330 boolean option, in case someone wants to add support for DSSSL
3332 Setup scm_keyword_prefix symbol.
3333 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3335 I've left keyword support disabled by default, since it doesn't
3336 seem to break the module system and it gives R4RS standard behaviour.
3337 It can be reactivated with (read-set! keywords 'prefix).
3339 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3341 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

3353 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3354 (idea from Mikael: make it a pair so scm_permanent object only
3356 (scm_read_hash_extend): don't call scm_permanent_object.
3357 (ideas from Mikael): if chr is already in the list, replace its
3358 procedure instead of appending it again. If proc is #f, remove
3360 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3362 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

3378 for extended # processing.
3379 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3380 scm_read_token): remove case_i, sharp arguments. Change callers.

3390 (default_case_i): definition removed.
3391 * read.c (scm_read_token): if case_i, downcase ic before doing
3394 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3396 * configure.in: Added configuration option `guile-debug'.
3397 Configure with --enable-guile-debug if you want a bunch of extra
3398 functions used for debugging when developing Guile.
3400 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3402 * procs.c (make-cclo): New undocumented debugging procedure: Make
3403 compiled closure with internal procedure PROC and length LENGTH.
3404 Only compiled if GUILE_DEBUG is defined.
3406 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3408 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3410 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3412 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3413 with 3 or more args internally to the evaluator.
3415 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3417 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3418 with 3 or more args internally to the evaluator. This is mainly
3419 because we don't want to pass entry and exit points of the
3420 debug support twice, but it also seems to increase the speed of
3421 the evaluator for such calls (e. g. (+ 1 2 3)).
3423 * backtrace.c (scm_display_application): New procedure:
3424 display-application; Set fancy printing parameters individually
3425 for different types of display (backtrace, error, application).
3426 (These should of course be customizable!)
3428 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3429 clear the CHECK-flags.
3431 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3433 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3435 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3437 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3438 from pairs with a GLOC in the car.
3440 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3441 otherwise `symbol-hash' will behave badly.
3442 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3443 we get segmentation fault!
3445 * symbols.c: Added #include "weaks.h". New functions:
3446 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3447 moved to an extraneous library when we split libguile.)
3449 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3451 * filesys.c (scm_stat): stat now takes fport arguments too as
3452 documented in the manual.
3454 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3456 * debug.c (scm_single_step): Bugfix: Call continuation with
3457 scm_call_continuation instead of throwing to it.
3459 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3461 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3462 argument wasn't declared to be optional.
3464 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3466 * stime.c (scm_init_stime): Add feature "current-time".
3468 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3470 * throw.h: prototype for scm_exit_status.
3471 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3472 args to derive an exit status. Allows (quit) to work from a
3474 (scm_exit_status): new function.
3477 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3479 * eval.c (scm_deval): Removed some old code.
3480 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3482 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3485 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3488 * procs.c: Introduce the existent C function scm_thunk_p at the
3489 Scheme level as well.
3491 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3493 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3494 used from C to easily lookup the value of a symbol in the current
3497 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3499 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3500 scm_init_unif in this file. This will also fix a previous problem
3503 * configure.in: Added AM_MAINTAINER_MODE
3505 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3507 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3510 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3512 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3513 source files that are not always included in libguile but should
3514 have their dependencies calculated by automake. This variable is
3515 recognized by automake, no further magic is needed.
3516 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3517 to deal exclusively with *.lo files, as it seems. The *.o files
3518 are built automatically when the corresponding *.lo file gets
3521 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3523 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3526 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3528 * unif.c (scm_array_set_x): minor change to argument error checking.
3530 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3532 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3533 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3534 They should only be included in the library at configure.in's
3536 (libguile_la_LDADD): Include the appropriate .lo files here.
3537 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3538 so we know when to build them (and their .lo bretheren).
3539 * configure.in (LIBLOBJS): New substituted variable. We let
3540 configure decide which .o files to include in LIBOBJS, and then
3541 put the corresponding list of .lo files in LIBLOBJS. The latter
3542 is what we pass to libtool.
3543 * Makefile.in, configure: regenerated.
3545 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3547 * symbols.c (scm_sysintern0): New function. Contains the core of
3548 old scm_sysintern but doesn't take a second value argument.
3549 (scm_sysintern): Now uses scm_sysintern0.
3550 (scm_sysintern_no_module_lookup): Renamed to
3551 scm_sysintern0_no_module_lookup and doesn't take a second value
3552 argument any longer.
3554 * symbols.h (scm_sysintern0: Added declaration.
3556 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3557 scm_sysintern when interning option keys. Otherwise we risk
3558 destroying the values of already interned variables.
3560 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3561 scheme-level boolean (use SCM_NFALSEP).
3563 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3565 (scm_backtrace): New function. (C version of old function from
3566 boot-9.scm) Motivation: Make it possible to display backtraces
3567 without depending on boot-9.scm. (I'm uncertain if this
3568 motivation is good enough...)
3570 * root.h (scm_root_state): Add member the_last_stack_var.
3571 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3573 * root.c (mark_root): Mark scm_the_last_stack_var.
3575 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3578 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3580 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3581 1. mark_lazy_catch didn't mark the smob.
3582 2. Both functions above have standard variants:
3583 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3584 free_lazy_catch --> scm_free0.
3586 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3588 * throw.c (scm_internal_lazy_catch): New function.
3589 (scm_lazy_catch): Rewritten to use it.
3590 (scm_ithrow): Handle the new lazy catch representation.
3591 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3592 that doesn't have a jmpbuf is a lazy catch clause.
3593 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3594 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3595 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3597 (scm_init_throw): Register the new lazy-catch smob type.
3598 * throw.h (scm_internal_lazy_catch): decl for new function.
3600 * throw.c (scm_internal_catch): Doc fixes.
3602 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3603 configure.in. Including this might cause problems if applications
3604 that link against libguile include their own copies of alloca, but
3605 if they're using autoconf, they should be adding libguile to LIBS
3606 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3607 the copy in libguile, and things will be okay. (I think.)
3609 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3611 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3613 strop.h: move prototypes too.
3615 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3617 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3620 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3621 etc. I deleted them from filesys.c long ago, but didn't
3622 notice they were here too (although ineffective since
3623 sys/stat.h wasn't included).
3625 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3627 * eval.c: Don't define alloca in GCC case. gcc will automatically
3628 use __builtin_alloca if appropriate.
3630 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3632 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3633 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3634 that values of automatic variables are preserved. See comments
3635 for safe_setjmp for details.
3637 Change from Thomas Morgan:
3638 * variable.c: Include eq.h.
3639 (var_equal): New function.
3640 (variable_smob): Use var_equal as the discriminator for variables.
3642 * throw.c (s_throw): Remove extraneous declaration.
3644 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3645 * eval.c: Add necessary CPP cruft to support that.
3646 * configure, Makefile.in, scmconfig.h.in: regenerated.
3648 Change from Thomas Morgan:
3649 * procprop.c (scm_procedure_properties): Convert the Scheme
3650 boolean returned by scm_procedure_p into a C boolean before using
3651 it as a condition for SCM_ASSERT.
3652 (scm_procedure_property): Likewise.
3654 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3655 indications of Unixness.
3658 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3660 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3662 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3664 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3665 "unknown # object" error messages.
3667 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3668 (scm_i_index) and declare it static. Add a 'direction' argument
3669 to indicate what way the search should go.
3670 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3672 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3673 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3675 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3677 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3679 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3680 to avoid clash with various scsh forks.
3682 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3684 The following two changes (ramap.c, throw.c) are motivated by the
3685 apparent unportability of forward declarations of static arrays of
3686 the form `static foo bar[];'.
3688 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3689 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3691 * throw.c (scm_throw): Moved above scm_ithrow.
3693 * options.h: Removed the extern declarations of scm_yes_sym and
3694 scm_no_sym since these are static.
3696 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3698 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3700 * Makefile.am: remove AWK=@AWK@.
3701 Add a rule for generating errnos.list.
3702 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3704 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3705 don't extract errnos, just set a variable (avoids the
3706 need to recompile error.c just because configure is run.)
3708 * unif.h: update prototypes.
3709 * unif.c (scm_uniform_array_read,write): change the offset and
3710 length arguments to start and end, for consistency.
3712 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3714 * ioext.h: update prototypes.
3715 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3716 scm_read_line_x, it's a more general procedure using an
3717 interface from scsh. read-line and read-line! are now defined
3719 Note that the new read-line trims the terminator
3720 by default, previously it was appended to the returned string. An
3721 optional argument specifies how to process the terminator (scsh
3722 compatible). For the old behaviour: (read-line port 'concat).
3723 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3724 returns a pair, but is converted to multiple values if the scsh
3727 socket.h: update prototypes.
3728 * socket.c (scm_recvfrom): for consistency with other procedures,
3729 take start and end as separate optional arguments.
3730 (scm_recv, scm_recvfrom): don't allow the second argument
3731 to be a size, only a buffer. Change the scheme names to
3732 recv! and recvfrom!. Don't return the buffer.
3734 * ioext.h, posix.h: move prototypes too.
3735 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3736 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3737 "read.h" and "unif.h".
3738 * ioext.c: include "chars.h"
3740 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3742 * dynl.c: The dynamic linking and module registration functions
3743 are now defined even when dynamic linking is not available for the
3744 host system. Some of their functionality can be done without
3745 dynamic linking; when it's really needed, they throw errors.
3747 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3749 * configure.in: Only define DYNAMIC_LINKING when one of the system
3750 dependent functions is detected.
3751 * dynl.c (scm_dynamic_func): New function to get the address of a
3752 function in a dynamic object.
3753 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3754 produced by scm_dynamic_func as the thing to call.
3756 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3758 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3759 (scm_register_module_xxx, scm_registered_modules,
3760 scm_clear_registered_modules): New functions.
3762 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3764 * symbols.c (scm_sysintern): Renamed to
3765 scm_sysintern_no_module_lookup.
3766 (scm_sysintern): New function to take the place of the old
3767 scm_sysintern. It uses the current toplevel lookup closure to give
3768 the symbol its value. This is a temporary hack to put packages
3769 like gtcltk into their own module.
3770 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3771 us whether `scm_top_level_lookup_closure_var' has been initialized
3773 * eval.c (scm_init_eval): Set it.
3775 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3777 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3778 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3780 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3782 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3783 scm_sys_dup): deleted: FD capability will be added to other
3785 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3786 scm_fd_free, fd_smob, scm_intern_fd.
3787 (scm_open): renamed from scm_sys_open. Return a port instead of
3788 an FD object. Make the mode argument optional.
3789 (scm_sys_create): deleted, it's just a special case of open.
3790 (scm_init_filesys): move interning of constants O_CREAT etc.,
3791 here (were previously using SCM_CONST_LONG macro).
3792 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3794 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3795 include "fports.h" and <stdio.h>
3796 (scm_stat, scm_select): don't support FD objects.
3798 * error.h: adjust scm_syserror_msg prototype.
3799 * error.c (scm_syserror_msg): take an extra argument for errno.
3800 Using the global value didn't always work, since it could be
3801 reset by procedure calls in the message or args arguments.
3803 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3804 I don't understand why the check was there (and what about the
3807 * strop.c (scm_string_copy): allow shared substrings to be copied.
3809 * unif.h: corresponding change to prototypes.
3810 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3811 recognize two new optional arguments: offset and length. Allow
3812 the port argument to be an integer (file descriptor, for scsh).
3813 Include <unistd.h> for "read" prototype.
3815 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3817 * socket.c: don't include filesys.h.
3819 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3821 * Makefile.am: add AWK=@AWK@ (?)
3823 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3825 Add a rule to generate errnos.c from errnos.
3826 * error.c (scm_init_error): include errnos.c.
3827 * errnos_cnvt.awk: new file, converts the list of errno codes to
3829 * errnos_get.c: new file.
3830 * errnos.default: new file, contains errnos to try if they can't
3831 be extracted from errno.h.
3832 * configure.in: if using GCC, try and extract errno codes from
3836 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3838 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3839 * Makefile.am: Made libguile into a libtool library.
3840 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3841 Set libtool_libs to indicate that libguile is a libtool library.
3842 See guile/ChangeLog for details.
3843 * .cvsignore: ignore "*.lo", the libtool library objects.
3845 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3847 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3848 use htons in getservbyport argument.
3850 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3852 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3853 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3856 * objprop.c (scm_object_property): No need to take the CDR of the
3857 value returned by scm_object_properties, since Aug 20 change.
3859 * configure.in: When checking for struct linger, #include
3860 <sys/types.h> as well as <sys/socket.h>. I've never known
3861 <sys/types.h> to cause any portability problems, and Solaris's
3862 <sys/socket.h> needs it.
3863 * configure: Rebuilt.
3865 I think the Sun compiler has chosen a perverse way to interpret
3866 ANSI declarations combined with K&R definitions. We'll
3867 appease it a little bit. But when it invades France, we fight.
3868 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3869 * print.h (scm_iprlist): Here too.
3870 * numbers.c (scm_divbigdig): Change definition to match
3871 declaration in numbers.h.
3872 * unif.c (scm_makflo): Change definition to match declaration in
3875 * init.c (scm_boot_guile): Don't return the value of
3876 scm_boot_guile_1. This function doesn't return a value;
3877 scm_boot_guile_1 doesn't return a value (or return at all).
3879 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3882 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3883 compile. I have a feeling this function is a bad idea anyway ---
3884 one should always test for features, not systems.
3886 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3887 semicolons. Only pure luck kept this from being noticed earlier.
3889 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3891 * socket.c (scm_recvfrom): Added missing semicolon.
3893 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3895 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3896 the buffer and start and end positions for scsh networking
3899 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3901 * configure.in: Revert previous change to this file; the problem
3902 is due to transient automake weirdness.
3903 * configure: Rebuilt.
3905 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3906 PLUGIN/guile.libs. configure generates the latter from the former.
3907 * Makefile.in: Rebuilt.
3909 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3910 need this if we install scripts, like guile-snarf.
3911 * configure: Rebuilt.
3913 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3915 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3917 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3919 * socket.c (scm_addr_vector): fix faulty scm_listify.
3921 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3923 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3924 style block comment is no longer considered an error.
3926 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3928 * PLUGIN/guile.libs.in: New file.
3929 * PLUGIN/guile.libs: Removed from repository.
3930 * configure.in: Create PLUGIN/guile.libs from
3931 PLUGIN/guile.libs.in. This is for including additonal libraries
3932 needed for dynamic linking.
3933 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3934 instead of PLUGIN/guile.libs.
3936 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3938 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3940 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3941 occurrences of the given element from the list, not just the
3942 first. This is how the Emacs Lisp functions behave, how the
3943 analogous Common Lisp functions behave, and (I believe) how the
3944 older Maclisp functions worked. I realize that this change may
3945 break code, but it seemed better to break it before the Guile
3948 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3949 Their prototypes were already present in gc.h, but they weren't
3951 (scm_init_storage): Initialize scm_protects.
3952 * root.c (scm_protects): New element of scm_sys_protects.
3954 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3956 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3958 * libguile.h: Added #include "libguile/net_db.h".
3960 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3961 30 change. That file is only meant for communication between the
3962 configuration process and load.c. If code linked against libguile
3963 wants to get at the paths mentioned in libpath.h, it can call
3964 functions declared in load.h.
3966 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3968 * libguile.h: Removed #include "libguile/fdsocket.h"
3970 * net_db.c: Added #include <sys/socket.h>.
3972 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3974 * filesys.c (scm_input_waiting_p): use select in preference to
3975 FIONREAD, since the latter doesn't detect EOF.
3976 Throw error if neither select nor FIONREAD available.
3978 * socket.c (scm_connect): take a port, not a fd object.
3979 (scm_fill_sockaddr): throw an error if fam is not recognised.
3980 (scm_bind): use scm_fill_sockaddr.
3981 (scm_listen): take a port, not a fd object.
3982 (scm_accept): take and return a port. return #f in the car if
3983 address can't be got
3984 (scm_sock_fd_to_port): new procedure.
3985 (scm_socket): use scm_sock_fd_to_port.
3986 (scm_addr_vector): throw error if unrecognised address type.
3987 take an extra argument with the calling procedure name.
3988 (scm_getsockname): take a port. return #f if address can't be got.
3989 (scm_getpeername): take a port. return #f if address can't be got.
3990 (scm_recvfrom): take a port. return #f for address component if can't
3992 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3993 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3995 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3997 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3998 use separate data pointers, to allow them to be designed
3999 independently and reused.
4000 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4001 Renamed from catch_body, catch_handler, and uncaught_throw; made
4003 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4005 (scm_catch): Use the above.
4006 (scm_throw): Don't bother printing a message for an uncaught
4007 throw; we establish a default handler in init.
4008 * throw.h (scm_internal_catch): Prototype updated.
4009 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4011 (struct scm_body_thunk_data): New structure, used as data
4012 argument to scm_body_thunk.
4013 * init.c (struct main_func_closure): New structure, packaging up
4014 the data to pass to the user's main function.
4015 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4016 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4017 scm_internal_catch to establish a catch-all handler, using
4018 scm_handle_by_message. This replaces the special-case code in
4020 (invoke_main_func): Body function for scm_internal_catch; invoke
4021 the user's main function, using the main_func_closure pointer to
4022 decide what to pass it.
4023 * root.c (struct cwdr_body_data): Remove handler_proc member.
4024 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4025 (cwdr_handler): Removed.
4027 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4029 * socket.h (SCM_P): update bind prototype.
4030 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4031 include "feature.h".
4032 (scm_socket): return a port, not a file descriptor object.
4033 include "fports.h" and <unistd.h>
4034 (scm_bind): take a port, not a file descriptor object.
4035 take an extra argument for address args.
4037 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4038 INADDR_NONE, INADDR_LOOPBACK.
4040 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4042 * init.c: include net_db.h and not fdsocket.h.
4043 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4045 * Makefile.am: corresponding changes.
4046 * socket.h: renamed from fdsocket.h, fix names.
4047 * net_db.h: renamed from socket.h, fix names.
4048 * socket.c: renamed from fdsocket.c.
4049 remove _sys from procedure names.
4050 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4051 add "socket" to features list.
4052 * net_db.c: renamed from socket.c.
4053 remove _sys from procedure names.
4054 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4055 add "net-db" to features list.
4056 include "net_db.h". don't include <sys/socket.h> or
4059 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4061 * tags.h (scm_tags): Removed comma at end of last enumerator.
4063 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4065 Don't use GCC extensions to allocate space for debugging frames.
4066 (Here he goes again! Why do we put up with this?!)
4067 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4068 an scm_debug_info structure, not an in-line array of them. Add
4069 'info' member, to say how many vect elements we've used, for eval
4071 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4072 a new variable debug_info_end to mark the end of vect, instead of
4073 the address of the 'info' pointer itself.
4074 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4075 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4076 (SCM_APPLY): Explicitly allocate space for debug.vect.
4077 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4078 * stacks.c: Adjusted for new debug frame structure.
4079 (RELOC_INFO, RELOC_FRAME): New macros.
4080 (stack_depth, read_frames): Use them, and new scm_debug_frame
4081 element 'info', instead of magically knowing that eval frames have
4082 an info pointer sitting after vect.
4083 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4085 (scm_init_stacks): Formatting tweaks.
4087 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4089 Give GCC more control flow information, so it can be sure that
4090 variables aren't used uninitialized.
4091 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4092 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4093 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4094 scm_misc_error): Tell GCC that these functions never return.
4095 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4096 out the field type, call abort if SCM_ASSERT returns, to placate
4098 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4099 scm_wta ever returns. We can't handle this case anyway, and this
4100 gives the optimizer more information.
4101 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4102 scm_wta ever returns.
4104 In some cases, the code is fine, but GCC isn't smart enough to
4105 figure that out; this usually happens when one variable is only
4106 initialized and used when a particular condition holds true, and
4107 we know that condition will never change within a given invocation
4108 of the function. In this case, we simply initialize the variables
4109 to placate the compiler, hopefully to a value which will cause a
4110 crash if it is ever actually used.
4111 * print.c (scm_iprin1): Initialize mw_pos.
4112 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4113 * throw.c (scm_ithrow): Initialize dynpair.
4114 * unif.c (scm_uniform_vector_ref): Initialize cra.
4115 * struct.c (init_struct): Initialize prot.
4116 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4118 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4119 if EXPR contains no expressions.
4121 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4123 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4124 cause an infinite loop (???). So much for the algebraic
4125 equivalency of variable-sized arrays and alloca...
4127 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4129 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4130 a SCM boolean, not a C boolean.
4132 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4134 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4135 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4136 rules for raising scm_mtrigger. Previously, unfortunate but not
4137 unlikely circumstances could result in almost constant invokation
4138 of the gc. Now, this situations should be less likely, but they
4139 are not prevented completely.
4141 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4143 * numbers.c (scm_fuck): Procedure removed; looks like old test
4145 * numbers.h: Prototype removed.
4147 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4149 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4150 array to a pointer, to match my Nov 21 change in eval.c.
4152 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4154 * libguile.h: Added #include "libguile/backtrace.h", #include
4155 "libguile/stacks.h".
4157 * strings.c (scm_string scm_make_string scm_string_ref
4158 scm_string_set_x scm_string_equal_p scm_string_append):
4159 Bugfix according to scm patch from Aubrey Jaffer:
4160 Corrected long-standing
4161 (not (eqv? (integer->char 128)
4162 (string-ref (make-string 1 (integer->char 128)) 0)))
4163 bug found by John Kozak <jk@noontide.demon.co.uk>.
4165 * strports.c, strports.h: Make scm_eval_0str return the value of
4166 the last expression evaluated (previously, it returned void).
4168 * strports.c, strports.h: New function: scm_read_0str. Does what
4171 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4173 * simpos.c (scm_getenv): return #f if string can't be found in the
4174 environment instead of throwing an exception, for compatibility
4175 with numerous other systems.
4177 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4179 * Makefile.am (.c.x): Use guile-snarf.
4180 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4182 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4184 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4186 * backtrace.c (scm_display_error_message): Made non-static, and
4187 renamed from display_error_message.
4188 * backtrace.h (scm_display_error_message): Added extern decl.
4189 * throw.c (uncaught_throw): Use it to display the error message.
4191 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4193 * inet_aton.c: Use #if 0, not #ifdef 0.
4195 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4197 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4198 to convert the returned value.
4199 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4200 the offset argument.
4202 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4204 Add new interface to catch/throw, usable from C as well as
4206 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4207 (scm_internal_catch): New function, replaces...
4208 (scm_catch_apply): Deleted.
4209 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4210 mechanism which is a bit more code, but can be used nicely from C
4211 and implement the Scheme semantics as well.
4212 (scm_internal_catch): This is the replacement; it's named after
4213 the analogous function in Emacs.
4214 (scm_catch): Reimplemented in terms of the above.
4215 (struct catch_body_data, catch_body, catch_handler): New
4216 functions, used by scm_catch.
4217 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4218 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4219 support for new cwdr.
4221 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4224 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4226 * acconfig.h: Added DYNAMIC_LINKING symbol.
4227 * configure.in: Add option and checks for dynamic linking.
4228 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4229 dynl.h: New files for dynamic linking support.
4230 * Makefile.am (libguile_a_SOURCES):
4232 (modinclude_HEADERS): Added "dynl.h".
4233 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4235 * init.c (scm_boot_guile_1): Call
4236 scm_init_dynamic_linking to initialize dynamic linking support.
4238 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4240 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4241 (as we Schemers say). It needs to be global, so that I can tweak
4242 it for the proper operation of unexec.
4243 (scm_boot_guile_1_live): New variable, see above.
4245 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4247 * guile-snarf.sh: Removed.
4248 * PLUGIN/guile.libs: Added dependency for -lm.
4249 * acinclude.m4: Renamed from aclocal.m4.
4250 * PLUGIN/greet: Removed.
4251 * Makefile.am, aclocal.m4: New files.
4252 * configure.in: Updated for Automake.
4254 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4256 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4257 and not top_level_lookup_thunk_var.
4259 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4261 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4263 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4265 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4266 Scheme function, instead of syntax. Single argument is now a
4269 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4271 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4272 scm_ra_divide): Properly terminate statements passed as arguments
4273 to IVDEP macros. (Thanks to Bernard Urban.)
4275 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4276 with non-constant sizes. (Thanks to Bernard Urban.)
4278 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4280 It's an "eval closure", not an "eval thunk." A thunk is a
4281 function of no arguments.
4282 * root.h (struct scm_root_state): Renamed
4283 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4284 (scm_top_level_lookup_closure_var): Renamed from
4285 scm_top_level_lookup_thunk_var.
4286 * root.c (mark_root): Uses changed.
4287 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4288 * init.c (scm_start_stack): Uses changed.
4289 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4290 Change scheme-visible name to *top-level-lookup-closure* from
4291 *top-level-lookup-thunk*.
4293 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4295 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4296 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4298 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4300 * gc.c (struct scm_heap_seg_data): Doc fixes.
4302 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4303 sweeping. Then, prepend each segment's free cells to its
4304 freelist, rather than wiping out the old value. (Thanks to Marius
4307 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4308 scm_check_freelist, scm_debug_newcell): New functions and
4309 variables, for debugging freelist problems.
4310 * pairs.h (SCM_NEWCELL): New debugging version added.
4311 * gc.h (scm_debug_newcell): Added extern declaration, used by
4312 debugging version of SCM_NEWCELL.
4314 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4316 On some systems <libc.h> conflicts with <unistd.h>, and should not
4317 be #included at all.
4318 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4319 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4320 * configure.in: Call it.
4321 * posix.c, filesys.c: Use its results to decide whether or not to
4323 * configure, scmconfig.h.in: Rebuilt with autoconf and
4326 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4328 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4329 pointer to the stdio stream before calling scm_setbuf0, so the
4330 latter will be able to retrieve it. I'm surprised this didn't
4331 segfault earlier. (Thanks to Christopher Lee.)
4333 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4335 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4338 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4340 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4341 number of stack narrowing specifier pairs. The first specifier in
4342 a pair controls inner border, the second the outer border. A
4343 number means cut that number of frames, a procedure object means
4344 cut until that object is found in operator position in a frame.
4346 * root.c (cwdr): Bugfix.
4348 * read.c: Recording of positions disabled by default.
4350 * procs.c (scm_closure_p): New function.
4352 * posix.c (scm_tmpnam): New function.
4354 * load.c: Added #include "throw.h".
4355 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4358 * load.c, load.h (scm_read_and_eval_x): New function.
4360 * eval.c: Renamed debug option "deval" to "debug".
4362 (scm_eval_x): `eval!' is no longer accessible from the scheme
4363 level. Motivation: We can't allow operations which introduce
4364 glocs into the scheme level. Guile's type system can't handle
4365 these as data. Use `eval' or `read-and-eval!' as replacement.
4367 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4368 SCM_CONSP since this is a macro!; Set vframe.prev to
4369 scm_last_debug_frame instead of 0. In this way we can look
4370 "above" the virtual start stack frame if we wish.
4371 (scm_debug_hang): New function: Useful for debugging Guile in
4372 certain tricky situations. Will probably be removed later...
4374 * debug.h: Changed semantics of debug option "backtrace". This
4375 option now only indicates whether we want automatic backtrace at
4378 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4380 * ports.c: #include "filesys.h"
4381 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4383 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4384 Motivation: This is system specific code which is related to file
4385 I/O. It also may use select. Added code by Gary Houston to
4386 detect presence of character in stdio buffers.
4388 * libguile.h: #include "libguile/libpath.h"
4390 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4391 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4392 SCM_SITE_DIR; Install libpath.h among the other include files.
4394 * load.c, load.h (scm_sys_package_data_dir): New function.
4396 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4398 * stacks.h: Bugfix: Don't use tail-array length field as stack
4399 length field! This screwed GC.
4401 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4403 * _scm.h: Added #ifndef around definition of macros min and max.
4405 * __scm.h: Added hooks for threads to plugin to in ints protection
4406 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4407 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4408 the main code in these macros duplicated and spread over multiple
4409 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4410 SCM_THREAD_SWITCHING_CODE.
4412 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4414 * snarf.h: New file.
4415 * guile-snarf.sh: New file.
4416 * Makefile.in (inner_h_files): Added snarf.h
4417 (ancillary, install, uninstall, distclean): Added actions for
4419 (.c.x): Use guile-snarf.
4420 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4421 (gen_c_files): Note that these depend on guile-snarf.
4422 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4423 now in "snarf.h". Added #include "snarf.h" to get them.
4424 * libguile.h: Added #include "snarf.h".
4425 (Patches applied and tweaked by Jim Blandy.)
4427 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4429 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4430 standards suggest against providing prototypes for system
4431 functions. Thanks to Greg Troxel.
4433 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4435 * strports.c (scm_eval_0str): New function.
4436 #include "read.h", to get prototype for scm_read.
4437 * Makefile.in (strports.o): Update dependencies.
4438 * strports.h: New prototype.
4440 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4441 scheme name from "int?" to "integer?". It seems to do the job.
4442 * numbers.h: Rename prototype too.
4443 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4446 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4447 scm_num_eq_p): Rename these according to R4RS conventions: call
4448 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4449 to making libguile R4RS compliant without ice-9...
4451 * load.c (scm_sys_search_load_path): Search for files under all
4452 extensions listed in the %load-extensions variable. If FILENAME
4453 is absolute, return it unchanged, without searching the load path.
4454 (scm_loc_load_extensions): New variable, pointing to
4455 %load-extensions' value cell.
4456 (scm_init_load): Initialize it, and the value it points to.
4457 (scm_primitive_load_path): Improve error reporting.
4459 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4460 of new Scheme variable %load-hook.
4461 (scm_primitive_load): Apply %load-hook to filename.
4463 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4465 * configure.in: add tests for figuring out whether buffered data
4466 is available in a FILE structure, which is needed by char-ready.
4468 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4471 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4472 exceptions using misc_error instead of syserror. It seems a bit
4473 odd to throw an exception if a string can't be found in the
4474 environment, but it's consistent with open-file, stat etc.
4475 (simpos.h): remove sys_ from getenv.
4477 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4478 occurs, throw an error instead of returning errno. Return value
4480 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4482 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4484 * filesys.c (scm_stat2scm): derive file type and permissions from
4485 the stat mode and append them to the returned vector.
4486 There isn't much overhead in doing this and it avoids the need to
4487 work with S_IRUSR et al. in Scheme.
4488 Define symbols scm_sym_regular etc.
4489 (scm_init_filesys): don't intern S_IRUSR etc.
4491 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4492 and s_primitive_load_path.
4494 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4496 * error.h: don't declare error symbols. prototype for scm_misc_error.
4498 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4501 * error.c: use SCM_SYMBOL to set up error keys.
4502 scm_misc_error: new procedure.
4504 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4506 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4507 between `#!' and `!#' is ignored.
4508 (skip_scsh_block_comment): New function.
4510 * feature.c (scm_set_program_arguments): New argument, FIRST.
4511 * feature.h: Update prototype.
4512 * init.c (scm_boot_guile_1): Pass new argument to
4513 scm_set_program_arguments.
4515 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4517 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4518 (scm_boot_guile): Call scm_set_program_arguments here, later than
4519 the old initialization.
4521 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4522 initialization procedure.
4523 - Delete in, out, err arguments; there are other perfectly good
4524 ways to override these when desired.
4525 - Delete result argument; this function shouldn't ever return.
4526 - Rename init_func argument to main_func, for less confusion.
4527 - Delete boot_cmd argument; main_func is more general.
4528 -Add 'closure' argument, to help people pass data to main_func
4529 without resorting to global variables.
4530 - Abort if reentered; don't bother returning an error code.
4531 - Call scm_init_standard_ports to set up the default/current
4532 standard ports; no need to pass them to scm_start_stack.
4533 - Remove code to evaluate the boot_cmd, and start the repl; let
4534 the user do something like that in main_func if they want.
4535 - Remove code to package up a return value; main_func can do any
4537 - Call exit (0), instead of returning.
4538 (scm_start_stack): Don't initialize the I/O ports here; that's
4539 weird. Delete in, out, err arguments. Move guts to
4540 scm_init_standard_ports, scm_stdio_to_port.
4541 (scm_init_standard_ports): New function, to set up current and
4542 default standard ports.
4543 (scm_start_stack, scm_restart_stack): Make these static.
4544 * init.h (scm_boot_guile): Adjust declaration.
4545 (scm_start_stack, scm_restart_stack): Remove externally
4546 visible declarations for these.
4547 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4549 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4550 written out several times in scm_start_stack.
4551 * fports.h: New declaration for the above.
4553 * feature.c (scm_set_program_arguments): New function.
4554 * feature.h: New declaration for the above.
4556 * ports.c: Formatting tweak.
4558 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4560 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4561 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4562 for obtaining the address of a car or cdr field. Motivation:
4563 &SCM_CXR make assumptions about the internal structure of the
4566 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4567 Motivation: see SCM_CXRLOC.
4569 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4570 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4571 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4572 Motivation: Safer use. Some other macros are defined in terms of
4573 these operations. If these are defined using the SCM_SETCXR
4574 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4575 to inefficiency and an <e1> with side-effects could potentially
4576 break. Also, these particular operations are heavily utilized in
4577 the garbage collector. In unoptimized code there will be a
4580 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4581 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4582 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4583 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4584 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4585 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4586 vports.c: Cleaned up use of pairs: Don't make any special
4587 assumptions about the internal structure of selectors and
4588 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4589 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4590 (Among other things, this change makes it easier to build Guile
4591 with certain compilers which have problems with casted lvalues.)
4593 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4595 * stacks.c: Improve selection of relevant stack frames when making
4596 a stack object. Introduce one level of indirection in the stack
4597 object to make it possible to "narrow" to a certain region of the
4598 stack. This facilitates making use of more clever algorithms (not
4599 implemented) for selecting relevant frames and gives a cleaner
4600 design since selection of frames can be done independently of
4601 extraction of frames from the real stack.
4602 (scm_stack_id): Also take #t as argument which means look at
4605 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4606 Turn n_tail into an integer directly representing current number
4607 of frames in stack. Add field tail.
4609 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4611 * debug.c (scm_make_memoized): Made it available at scheme level.
4612 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4613 SCM_NIMP before applying heavier predicates in argument checking.
4614 (scm_local_eval): Also take memoized object as argument.
4616 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4617 aren't created with zero length, but should such a strange
4618 creature suddenly turn up...
4620 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4622 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4623 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4625 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4627 * variable.c (scm_make_variable): Make the name hint optional, as
4629 (anonymous_variable_sym): Renamed from variable_sym. All uses
4632 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4633 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4634 of scm_primitive_load_path was also changed to
4635 "primitive-load-path", from "%try-load-path". Callers changed.
4636 We'd like to respect the convention that a function named
4637 "try-mumble" should behave just like the function called "mumble",
4638 but return #f instead of signalling some error.
4639 * load.h: Rename prototypes.
4641 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4643 * print.c (make_print_state, grow_print_state), print.h: Modified
4644 the print state representation: Don't use a tail array for
4645 recording of circular references. Resizing of the print state
4646 structure invalidates the print state pointer. To avoid passing
4647 around an indirect print state reference to all printing
4648 functions, we instead let the print state reference a resizable
4651 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4653 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4654 Don't crash when passed an improper list terminated by a
4655 non-immediate value.
4657 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4659 Allocate data for structures on an eight-byte boundary, as
4660 required by the tagging system.
4661 * struct.c (alloc_struct): New function.
4662 (scm_make_struct, scm_make_vtable_vtable): Call it.
4663 * struct.h (scm_struct_n_extra_words): Bump to 3.
4664 (scm_struct_i_ptr): New "field".
4665 * gc.c (scm_gc_sweep): When we need to free the data, use the
4666 information stored by alloc_struct to find the beginning of the
4667 block allocated to the structure, so we can free it.
4669 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4671 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4674 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4675 (scm_debug_info): New member: id.
4677 * stacks.c: Stacks are now represented as structs; Stacks have an
4678 id given to them by `start-stack'.
4679 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4681 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4682 Changed stack representation.
4684 * debug.c (scm_procedure_name): Try procedure property `name' for
4685 compiled closures aswell.
4687 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4689 * eval.c: scm_i_name moved to gsubr.c
4690 (scm_m_define): Record names of all kinds of procedure
4691 objects. (Earlier, only closures were recorded.)
4693 * procprop.h: Added declaration of scm_i_name.
4695 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4696 (scm_make_gsubr): Record names of compiled closures.
4698 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4700 * debug.c, debug.h: Removed obsolete code.
4702 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4703 stacks.c: Renamed regs --> scm_contregs.
4705 * print.c (scm_free_print_state): Cleanup print state before
4706 returning it to pool. It is better to do it here than in
4707 scm_prin1 since scm_prin1 is called often.
4709 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4710 s_set_source_property_x): Check that first argument is a pair or a
4713 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4714 scm_i_line, scm_i_column and scm_i_breakpoint global.
4716 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4717 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4720 * debug.h: Added debug object smob declaration and macro
4723 * configure.in: Build with backtrace.o and stacks.o if debug
4726 * Makefile.in: Added entries for new files: backtrace.c,
4727 backtrace.h, stacks.c and stacks.h.
4729 * symbols.c (scm_sym2ovcell): Fixed documentation.
4731 * _scm.h (min, max): Added.
4733 * async.c: Moved `min' macro to _scm.h.
4735 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4736 SCM_BACKTRACE_INDENT.
4738 * eval.c: Added new debug options `maxdepth' and `indent'.
4740 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4742 * print.h: Added selector SCM_PRINT_STATE.
4744 * print.c: New functions: scm_make_print_state,
4745 scm_free_print_state.
4747 * print.h: Added declarations for scm_make_print_state,
4748 scm_free_print_state.
4750 * debug.c (scm_m_start_stack): New acro.
4752 * debug.h: Small cleanup.
4754 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4757 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4782 More prototype-related changes from Marius Vollmer:
4783 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4784 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4785 * ports.h (ptobfuns): Added prototypes. This means some casting in
4787 * fports.c: Added casts for initializations, since the functions
4788 are defined to take FILE * as their stream argument, not SCM.
4789 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4790 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4791 to `char *str_data' to conform to prototype.
4793 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4795 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4797 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4799 * stime.c, stime.h: use SCM_P method.
4801 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4803 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4804 be given at least two arguments. Insist that lst's last element
4805 be a list, but don't make any requirements of its predecessors.
4807 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4809 * eval.c (scm_nconc2last): Revert last change; there seems to be
4810 other stuff going on here.
4812 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4814 * eval.c (scm_nconc2last): Make sure that each element of lst
4815 (which is a list of argument lists, except for the tail) is a
4816 proper list, i.e., finite and terminated by '().
4818 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4820 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4823 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4824 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4827 * vectors.c (scm_make_vector): Fill vectors with the undefined
4828 value, to help make Guile Scheme code more portable to other
4831 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4832 * symbols.h, tags.h: Doc fixes.
4834 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4836 * async.c (scm_take_signal): Doc fixes.
4838 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4840 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4841 want to subtract it from the modulus; we just want to leave it
4844 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4846 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4849 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4851 * throw.c (scm_catch_apply): Finished implementation of
4854 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4856 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4858 (scm_init_filesys): set "i/o-extensions" feature.
4861 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4863 * Makefile.in (root.o): Correct dependencies.
4865 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4867 * Makefile.in: Added dependency entry for root.o.
4869 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4870 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4872 * init.c (scm_start_stack): Set initial root continuation number
4875 * procs.c: New function: scm_thunk_p.
4877 * procs.h: Added declarations of scm_thunk_p.
4879 * root.c: Renamed `call-with-new-root' -->
4880 `call-with-dynamic-root'.
4881 (cwdr): Removed allocation of new root state. This should be done
4882 separately by use of scm_make_root.
4883 (scm_apply_with_dynamic_root): New function: Does what it
4884 sounds like. Needed when spawning threads.
4886 * root.h: Added member last_debug_frame to root state.
4887 Added #include "libguile/debug.h"
4889 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4890 arguments. The motivation is that code in root.c needs catch
4891 functionality, and we want to avoid code duplication.
4892 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4893 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4894 handlers that run without popping the stack into the dynwind
4897 * throw.h: Added prototypes for scm_catch_apply and
4900 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4902 * root.h (scm_root, scm_set_root): Decouple thread support details
4903 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4904 SCM_SET_THREAD_LOCAL_DATA.
4906 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4907 and tortoise scanning loop.
4909 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4911 * Makefile.in: Rebuild dependencies.
4913 * libguile.h: #include "libguile/print.h" before "smob.h", since
4914 the latter uses the print_state structure.
4916 * throw.c (scm_ithrow): Use the correct variable when checking to
4917 see if a given element of scm_dynwinds is a valid catch.
4919 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4920 structure, abort; don't just silently ignore the garbage.
4922 * _scm.h: #include "print.h" here, since it seems to be used just
4924 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4925 strports.c, unif.h: Don't #include "print.h".
4927 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4929 * feature.h (scm_loc_features): Removed external declaration.
4930 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4932 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4934 * feature.c (scm_init_feature): Added threads feature (needs to be
4935 initialized here, since features doesn't exist when
4936 scm_init_threads is called).
4938 * libguile.h: Added #include "libguile/../threads/threads.h".
4939 (This is a kludge to get thread support working. This should be
4942 * configure.in, acconfig.h: Added flags for thread support.
4944 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4947 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4948 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4951 * _scm.h: Added conditional #include "threads.h"
4953 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4954 SCM_THREADS_SWITCHING_CODE.
4956 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4957 allocate the basic dynamic root object.
4958 (scm_boot_guile): Added call to scm_init_root.
4960 * root.c, root.h: Added root smob.
4961 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4962 functions: Implements dynamic roots mostly according to spec in
4963 SCM manual. Main difference is that the second argument is a
4964 throw handler rather than an error "thunk".
4966 * root.h: Added declaration of scm_init_root.
4968 * root.c: Added #include "genio.h", #include "smob.h", #include
4969 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4971 (scm_init_root): Added #include "root.x".
4973 * throw.c: Added #include "stackchk.h"
4974 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4975 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4976 can be used in scm_call_with_new_root; Added reenabling of stack
4977 checking when catching a throw.
4979 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4981 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4983 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4984 element is not found, as per R4RS.
4986 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4988 * list.c: Doc fixes throughout.
4990 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4992 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4993 declare the char * to be const. Avoids a warning in rgx.c.
4995 * ports.h: spelling fix.
4997 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5000 * load.c (scm_sys_try_load_path): throw an error if file not found
5001 (like it says it in NEWS).
5003 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5005 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5006 PROPS slot to '(), not #f; it's an empty alist.
5008 * throw.h, throw.c: Use SCM_P instead of #if hair.
5010 Remove special support for uncaught throws; see throw.c for
5012 * throw.c (uncaught_throw): New function.
5013 (scm_ithrow): Call uncaught_throw if we don't find a throw
5014 target; don't mess with scm_bad_throw_vcell.
5015 (scm_bad_throw_vcell): Variable deleted.
5016 (scm_init_throw): Don't initialize it.
5018 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5021 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5023 * numbers.c (scm_istr2int): If the number is short (as most
5024 numbers are), just call scm_small_istr2int to deal with it.
5025 (scm_small_istr2int): New function, created by un-#ifdefing the
5026 non-bignum version of scm_istr2int and renaming it.
5028 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5030 * load.c (scm_sys_try_load): don't check whether value returned
5031 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5032 Change the Scheme name from %try-load to primitive-load.
5034 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5035 Can avoid passing a message, allowing it to be derived in the
5036 error handler (e.g., if we want to throw to the key both from
5039 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5041 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5042 references now have a new appearance which is more compact and
5043 also gives a clue about what the target of the reference is.
5044 By setting parameters in the print state, more fancy printing can
5045 be achieved. This is used by the (not yet commited) backtrace
5048 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5050 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5053 * print.c: Added #include "struct.h". Removed function
5056 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5057 scm_iprin1. Removed prototype for scm_prlist.
5059 * arbiters.c (prinarb),
5060 async.c (print_async),
5061 debug.c (prindebugobj, prinmemoized),
5062 eval.c (prinprom, prinmacro),
5063 filesys.c (scm_fd_print, scm_dir_print),
5065 mallocs.c (prinmalloc),
5066 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5067 smob.h (scm_smobfuns),
5068 srcprop.c (prinsrcprops),
5070 unif.c, unif.h (scm_raprin1, rapr1),
5071 variable.c (prin_var): Changed argument `int writing' to
5072 `scm_print_state *pstate'.
5074 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5075 that it will be called before scm_init_print.
5077 * print.c (scm_prin1): Print states are now allocated when calling
5078 scm_prin1 and then passed around to all printing functions as an
5079 argument. A cache `print_state_pool' enables reuse of print
5081 (scm_make_print_state): New function.
5082 (scm_iprin1): Adaption to print states.
5083 (scm_iprlist): An initial "hare and tortoise" scan brings down
5084 time complexity to O (depth * N). (Better time complexity will be
5085 achieved when the printing code is completely rewritten.)
5087 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5089 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5090 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5091 it gets done whether or not the cache variable has a value.
5093 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5095 Distinguish #f and ().
5096 * __scm.h: #undef SICP.
5097 * pairs.h (SCM_EOL): Delete this definition, equating it with
5099 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5100 the value it used to have. Doc fixes, too.
5102 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5104 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5105 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5106 Lord's implementation of structs, allowing for tail arrays as
5107 described in the manual. Also fixed some bugs. (Both the interface
5108 and the implementation should be improved.)
5110 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5112 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5113 People who whish to see the source can do `(print-enable 'source)'.
5114 Removed #ifdef DEBUG_EXTENSIONS.
5116 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5118 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5119 integer (assuming for now accepting an integer is a good thing).
5121 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5122 %S will be used instead for write'ing arguments.
5124 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5125 asserts. fix a few other asserts.
5126 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5127 scm_uniform_vector_ref, scm_array_set_x,
5128 scm_dimensions_to_unform_array): change args in
5129 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5130 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5131 scm_substring_fill_x): likewise.
5132 gsubr.c (scm_gsubr_apply): likewise.
5133 eval.c (SCM_APPLY): likewise.
5135 * eval.c (4 places): replace scm_everr with lgh_error or
5138 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5139 scm_memory_error): new procedures.
5140 scm_everr: deleted. can use scm_wta, dropping first two args.
5141 scm_error: convert NULL subr to SCM_BOOL_F.
5143 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5146 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5149 * error.c, error.h: new error keys: scm_arg_type_key,
5150 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5152 scm_wta: reimplement using lgh_error instead of scm_everr.
5154 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5156 * gdbint.c: scm_lread now has one more argument.
5158 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5159 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5160 loading source from non-file ports, which, e. g., happens when
5161 using the Emacs interface).
5163 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5166 * read.c: Added code for recording of positions of source code
5167 expressions; New functions: recsexpr, scm_lreadrecparen;
5168 _scm_make_srcprops --> scm_make_srcprops
5169 (scm_flush_ws): Removed updating of positions counters. This work
5170 is already done by scm_gen_getc
5172 * read.h: Added prototype for scm_lreadrecparen
5174 * print.c: Added #include "alist.h"
5176 * eval.c: Added #include "hash.h"
5178 * eq.c: Added #include "ramap.h"
5180 * options.c: Documentation fixes.
5182 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5183 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5184 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5185 --> scm_make_srcprops
5187 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5188 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5189 function calls in the definition of the whash access macros.
5191 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5193 * init.c (scm_boot_guile): Add level of indirection to
5194 scm_boot_guile_1() to ensure that stack base pointer is properly
5195 initialized. There was no guarantee that variable i was the
5196 highest/lowest variable on stack (i.e. the call frame of
5197 scm_boot_guile was not completely protected from gc).
5199 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5201 * ports.h (scm_port_table): put back file_name, it will be used to
5202 support debugging. Undo related changes in fports.c, ioext.c,
5205 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5207 * ports.h (scm_port_table): remove file_name member for now, it seems
5209 * fports.c (scm_open_file): don't set file_name in PTAB.
5210 (prinfport): don't use file_name in PTAB.
5211 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5212 * ports.c (scm_add_to_port_table): don't intialize file_name.
5213 (scm_port_file_name): remove for now.
5214 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5216 * fports.h (scm_mkfile): prototype deleted.
5217 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5219 * debug.c, unif.c: use scm_out_of_range instead of
5220 wta for range errors (ASSERT still needs work).
5222 * error.c, error.h (scm_out_of_range): new procedure.
5224 * error.c, error.h (scm_out_of_range_key): new key.
5226 * posix.c (scm_sync): #else was missing.
5228 * error.c, error.h: append _key to names scm_num_overflow and
5231 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5232 of consing an empty list.
5233 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5234 of macros, saves code and string space.
5235 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5236 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5237 lower case. Rename scm_syserror_m to scm_syserror_msg.
5238 error.h: prototypes for new procedures.
5240 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5242 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5244 * error.c, error.h: setup scm_num_overflow key.
5246 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5247 Remove definition of SCM_OVSCM_FLOW.
5249 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5251 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5252 explicit message and args.
5254 * error.c, error.h, __scm.h: change system_error_sym to
5257 * error.c (system_error_sym): remove leading %% from the Scheme name
5260 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5262 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5264 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5265 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5266 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5267 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5268 renamed. (These were introduced by unsupervised name
5271 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5273 * print.c: Added code for detection of circular references during
5274 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5275 a hook for printing of closures (accessible via print options).
5276 This leads to a split of calls to scm_iprin1 into two classes:
5277 elementary print operations (e. g. the code which prints a smob)
5278 still use scm_iprin1 while top level calls (like scm_display) use
5279 scm_prin1. scm_prin1 begins by clearing the data structure used
5280 to record reference information.
5282 * print.h: Added declarations of scm_prin1 and scm_prlist.
5284 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5286 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5288 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5290 * error.c (err_head): scm_iprin1 --> scm_prin1
5292 * debug.c: Adjusted header comment.
5296 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5298 * strerror.c: Doc fix.
5300 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5302 * gdbint.c (gdb_read): Now possible to run during GC.
5303 (unmark_port, remark_port): New functions.
5305 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5307 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5308 of allocating a new string object. Also, increase size by
5309 the factor 2 instead of 1.5.
5311 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5313 * __scm.h (SCM_P): Corrected to run under traditional C.
5315 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5318 * async.c: Calls to scm_sysintern corrected.
5320 * async.h (scm_async_clock): Redundant declaration removed.
5322 * continuations.c (scm_dynthrow): Redundant declaration removed.
5324 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5325 Definition typos corrected.
5327 * debug.h: Missing declarations of functions in debug.c added
5330 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5331 Missing declarations to functions in eval.c added.
5333 * filesys.c: Possibly uninitialized variable rv.
5335 * gc.h (scm_object_addr, scm_unhash_name): Missing
5336 declarations of functions defined in gc.c added.
5338 * genio.c: Possible typos str_data -> wstr_data. ???
5340 * genio.c: Possibly unintended shadowing of local variable
5341 `int c' (gotos out of scope of inner `c'). ???
5343 * init.c: Uninitialized `SCM last' may be used.
5345 * ioext.h: (scm_sys_isatty_p): Typo.
5347 * list.h (scm_list_head): Missing prototype for function in
5350 * numbers.c (scm_two_doubles): Changed from extern to static
5351 (is used only within numbers.c).
5353 * numbers.h: Repeated declarations removed.
5355 * ports.h (scm_close_all_ports_except): Declaration for the
5356 function defined in ports.c added.
5358 * posix.h: Missing declarations added.
5360 * procs.h (scm_make_subr_opt): Missing declaration added.
5362 * socket.h (scm_sys_gethost): Missing declaration added.
5364 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5366 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5367 Missing declarations added.
5369 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5371 * struct.c: Uninitialized variable `SCM answer' may be used.
5373 * unif.c (l2ra): Declaration prototype.
5375 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5376 defined in ramap.c).
5378 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5379 Redundant declarations removed (they are in ramap.h).
5381 * variable.h (scm_make_udvariable,
5382 scm_make_undefined_variable): Declaration corrected to
5383 correspond variable.c.
5385 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5386 Missing declarations added.
5388 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5390 * Makefile.in (distclean): Don't forget to delete fd.h.
5392 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5394 * fd.h.in, tags.h: Trivial cleanups.
5396 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5397 marksweep.h just declared functions from gc.c.
5398 * gc.h, libguile.h: Don't #include "marksweep.h".
5399 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5400 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5401 dependencies updated.
5403 * libguile.h: Don't #include "files.h"; it's been deleted.
5405 * files.c (scm_sys_delete_file): Moved to filesys.c.
5406 File is now empty; deleted.
5408 * filesys.c: scm_sys_delete_file is now here. Remove
5409 #if's; they seem to rely on remnants of an old portability
5410 regimen. If the problems come up again, solve them properly,
5411 using autoconf. Specifically: Don't test M_SYSV, and #define
5412 remove to be unlink if it's #defined; don't use remove just
5413 because HAVE_STDC_HEADERS is #defined.
5414 * filesys.h: Add declarations for scm_sys_delete_file.
5415 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5416 files.o, files.h, files.c, and files.x.
5417 * init.c: Don't #include "files.h", and don't call scm_init_files.
5419 Use SCM_P instead of PROTO; the latter intrudes on the user's
5421 * params.h: Deleted; definition of SCM_P moved to...
5422 * __scm.h: ... here, where it replaces PROTO macro.
5423 * libguile.h, smob.h: Don't #include "params.h".
5424 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5425 smob.h: Fix prototypes accordingly.
5426 * Makefile.in: Update dependencies.
5427 (inner_h_files): Remove params.h.
5429 * gc.c: #include "gc.h"; every module should include its header,
5430 to let the compiler cross-check the declarations against the
5433 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5434 simpos.h: #include "libguile/__scm.h".
5436 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5438 * init.c: Don't forget to #include smob.h and init.h.
5439 * Makefile.in: Dependencies updated.
5441 * smob.h: Use PROTO instead of #if __STDC__.
5443 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5445 * __scm.h: Doc fixes.
5447 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5448 <angles>; this allows `make depends' to work properly.
5450 * libguile.h: #include smob.h and pairs.h before the others; they
5451 define typedefs used by other headers.
5453 C files should #include only the header files they need, not
5454 libguile.h (which #includes all the header files); the pointless
5455 recompilation was wasting my time.
5456 * Makefile.in (all .o dependency lists): Regenerated.
5457 * libguile.h: Don't try to get a definition for size_t here...
5458 * __scm.h: Do it here.
5459 * _scm.h: Since this is the internal libguile header, put things
5460 here that all (or a majority) of the libguile files will want.
5461 Don't #include <libguile.h> here; that generates dependencies on
5462 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5463 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5464 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5561 * weaks.c: Get "weaks.h".
5563 * stackchk.h: #include "libguile/debug.h",
5565 * print.h, read.h: #include "options.h", since everyone who uses
5566 either of these files will need that.
5568 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5569 anyone who uses this file will need them to define the smob
5570 printing functions. Also, get markers.h, since people will need
5571 to #define the mark functions.
5573 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5574 * ports.h: ... to here.
5576 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5577 don't rely on archaic C default type rules.
5579 * fports.h: #include "libguile/ports.h", since you need that in
5580 order to parse this.
5582 * genio.h: #include "libguile/print.h", because you need that to
5583 parse this; don't bother #including "ports.h", since print.h gets
5586 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5588 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5589 this; it's now a reference to an element of *scm_root.
5591 * debug.h: Don't #include "options.h"; the compiler won't be able
5592 to find that once the headers are installed; instead, #include
5593 "libguile/options.h".
5594 * gc.h: Same, with marksweep.h.
5595 * mbstrings.h: Same, with symbols.h.
5596 * scmhob.h: Same, with _scm.h.
5597 * smob.h: Same, with params.h.
5599 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5600 C files; there's no need for this, and it forces recompilations
5603 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5605 * error.c (scm_error): declare scm_error_callback.
5607 * error.h: prototype for scm_error_callback.
5609 * __scm.h: define lgh_error.
5610 (SCM_SYSERROR): redefine using lgh_error.
5612 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5614 * error.c (scm_error): new procedure.
5616 * error.h: prototype for scm_error.
5618 * Makefile.in (install): install scmconfig.h from the current
5619 directory, not $(srcdir).
5621 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5623 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5624 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5625 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5626 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5627 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5628 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5629 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5630 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5631 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5632 vports.h, weaks.h: #include "libguile/__scm.h", not
5633 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5634 dependencies are within libguile properly.
5636 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5638 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5639 when scmconfig.h doesn't exist.
5641 * load.c (scm_sys_try_load): Correct spelling.
5643 * feature.c (scm_loc_features): Make this static.
5645 * Makefile.in (libpath.h): Omit trailing slash from path. We
5646 shouldn't require it of users, so why put it here?
5648 Move code to initialize and search %load-path from ice-9 to C
5649 code, so we can use the load-path to find the ice-9 boot code;
5650 this makes it easier to run Guile without installing it. See
5651 corresponding changes in guile/Makefile.in.
5652 * feature.c: Move stuff concerned with the load path to load.c.
5653 (scm_compiled_library_path): Deleted.
5654 Don't #include libpath.h here.
5655 * feature.h: Don't mention scm_compiled_library_path.
5656 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5657 <sys/stat.h>, and <unistd.h> (if present).
5658 (R_OK): #define if the system hasn't deigned to.
5659 (scm_loc_load_path): New variable.
5660 (scm_init_load_path, scm_sys_search_load_path,
5661 scm_sys_try_load_path): New functions.
5662 (scm_init_load): Initialize scm_loc_load_path to point to the
5663 value cell of the Scheme %load-path variable.
5664 * load.h: Add declarations for scm_sys_search_load_path,
5665 scm_sys_try_load_path.
5666 * init.c: Call scm_init_load_path.
5667 * Makefile.in (feature.o, load.o): Dependencies updated.
5669 * load.c, load.h: Rewrite using PROTO macro.
5671 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5673 * gc.c (scm_cellp): New function: C predicate to determine if an
5674 SCM value can be regarded as a pointer to a cell on the heap.
5676 * gc.h: Added declaration of scm_cellp.
5678 * gdb_interface.h: New file: The GDB interface header from the GDB
5681 * gdbint.c: New file: GDB interface.
5683 * gdbint.h: New file: GDB interface.
5685 * libguile.h: Added #include <libguile/gdbint.h>.
5687 * init.c (scm_boot_guile): Added scm_init_gdbint.
5689 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5690 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5691 found if object files and source are kept separate).
5693 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5695 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5697 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5699 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5700 TK_SRC_DIR; they're not relevant any more.
5702 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5703 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5705 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5707 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5708 search path, so we can find the <libguile/MUMBLE.h> headers.
5710 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5712 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5713 implicit in the .c.o rule.
5714 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5717 Put the library path in a header file, instead of passing it on
5718 the command line in every compilation.
5719 * Makefile.in (libpath.h): New target.
5720 (feature.o): Depend on libpath.h.
5721 (clean): Delete libpath.h.
5722 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5723 * feature.c: ... #include "libpath.h" here.
5724 * .cvsignore: Ignore libpath.h.
5726 Don't install the unwashed masses of Guile header files in the
5727 main #include path; put most of them in a subdirectory called
5728 'libguile'. This avoids naming conflicts between Guile header
5729 files and system header files (of which there were a few).
5730 * Makefile.in (pkgincludedir): Deleted.
5731 (innerincludedir): New variable; this and $(includedir) are enough.
5732 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5733 (installed_h_files): Divide this up. Now this variable lists
5734 those header files which should go into $(includedir) (i.e. appear
5735 directly in the #include path), and ...
5736 (inner_h_files): ... this new variable says which files appear in
5737 a subdirectory, and are referred to as <libguile/mumble.h>.
5738 (h_files): List them both.
5739 (install): Create innerincludedir, not pkgincludedir. Put
5740 the installed_h_files and inner_h_files in their proper places.
5741 (uninstall): Corresponding changes.
5742 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5743 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5744 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,

5750 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5751 vports.h, weaks.h: Find __scm.h in its new location.
5752 * __scm.h: Find scmconfig.h and tags.h in their new locations
5753 (they're both "inner" files).
5755 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5757 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5759 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5761 * posix.c: Doc fixes.
5763 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5765 * socket.c: Don't include a prototype for inet_aton; just use a
5766 K&R style declaration, to avoid warnings but minimize the chance
5767 of conflicts with the system.
5769 On NextStep, <utime.h> doesn't define struct utime, unless we
5770 #define _POSIX_SOURCE before #including it.
5771 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5772 * acconfig.h: New comment text for above CPP symbol.
5773 * configure.in: Call it.
5774 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5776 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5778 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5779 testing for __EMX__.
5781 * posix.c: #include <libc.h>, if it exists.
5783 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5784 don't even know if the latter exists.
5786 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5787 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5788 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5790 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5792 (scm_init_posix): Use them when initializing the Scheme constants
5795 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5797 * Makefile.in (libdir, includedir, bindir): Use the
5798 autoconf-supplied values, instead of deriving them ourselves.
5799 (pkgincludedir, datadir, pkgdatadir): New variables.
5800 (install, uninstall): Put the header files in a special
5801 subdirectory, not in the main search path.
5803 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5804 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5806 * Makefile.in (IMPLPATH): Deleted; never used.
5808 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5809 on the Tcl/Tk source any more.
5810 (INCLUDE_CFLAGS): Remove references to the above.
5812 * Makefile.in (version.o): Corrected dependencies.
5814 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5816 * libguile.h: #include "version.h"
5818 * init.c (scm_boot_guile): Call scm_init_version.
5819 * gscm.c (gscm_run_scm): Call scm_init_version.
5821 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5822 GUILE_VERSION): AC_DEFINE these.
5823 (acconfig.h): #undef the above symbols.
5825 * Makefile.in (libobjs): Add version.o.
5826 (installed_h_files): Add version.h.
5827 (c_files): Add version.c.
5828 (gen_c_files): Add version.x.
5829 (version.o): New rule.
5830 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5831 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5839 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5840 weaks.o): Add version.h to dependency lists.
5841 (markers.o): Remove duplicate rule.
5843 * version.h: New file.
5845 * version.c: New file.
5847 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5849 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5850 array; use it appropriately. Since GCC is quite happy to
5851 subscript functions, it never warned us about this; we should use
5852 -Wpointer-arith in the future. I guess we never tested
5855 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5857 * socket.c: Doc and copyright fixes.
5859 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5861 * debug.c: Fixed and improved gdb support.
5863 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5865 * socket.c: Added declaration of inet_aton to avoid compiler
5866 warning. (Hope this solution is correct.)
5868 * stime.c: Added declaration of ftime. (This is missing in
5871 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5873 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5875 * Makefile.in (c_files): add strerror.c.
5877 * strerror.c: new file from Emacs' sysdep.c.
5878 maybe configure should also check for sys_errlist.
5880 * configure.in (AC_REPLACE_FUNCS): add strerror.
5882 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5884 * debug.c (scm_init_debug): Added initialization for
5885 scm_evaluator_traps.
5887 * debug.h, debug.c: Various name changes.
5888 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5889 "debug-options-interface". See commentary in options.c.
5891 * options.h, options.c: Options now have documentation strings.
5892 Also added a long explanatory commentary.
5894 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5897 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5898 last_debug_info_frame is now updated in all cases.
5900 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5903 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5905 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5906 Added option STACK_CHECKING.
5908 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5910 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5912 * __scm.h: Removed symbols for debugging support.
5914 * acconfig.h: Added symbols for debugging support.
5916 * configure.in: Added user option for debugging support.
5917 --enable-debug will include the debugging code into libguile.a.
5919 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5920 scm_relocate_chunk_to_heap.
5922 * debug.c: New file: low-level debugging support. It also
5923 includes support for debugging with gdb. (The extensions to gdb
5924 are written by Per Bothner at Cygnus.)
5926 * debug.h: New file: low-level debugging support.
5928 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5929 argument pairs. Extensive modifications to the debugging
5930 evaluator. Added "SECTION:" commentaries to clarify what happens
5931 when, during double compilation. Renamed EVALIMP --> EVALIM.
5932 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5933 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5934 the beginning of the file. New procedure: scm_unmemocopy.
5935 Added some global state variables needed by the debugging
5936 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5937 check_entry, check_apply, check_exit, debug_options and
5938 evaluator_traps. New acro: undefine.
5940 * eval.h: Renamed EVAL --> XEVAL.
5942 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5943 --> scm_make_weak_key_hash_table.
5945 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5946 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5948 * libguile.h: Conditionally include debug.h
5950 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5951 scm_object_properties shouldn't return handle. `handle' now gets
5952 initialized in scm_set_object_properties_x. scm_object_properties
5953 doesn't any longer create an entry in scm_object_whash.
5955 * options.c: New file: handling of run time options.
5957 * options.h: New file: handling of run time options.
5959 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5961 * print.c: New procedure: scm_print_options
5963 * print.h: Defines for print options.
5965 * read.c: New procedure: scm_read_options
5967 * read.h: Defines for reader options.
5969 * root.h: Added scm_source_whash among scm_sys_protects.
5971 * srcprop.c: New file: source properties.
5973 * srcprop.h: New file: source properties.
5975 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5976 (Bug found by A. Green.)
5978 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5980 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5982 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5984 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5986 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5987 and should be called by the final client.
5989 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5991 * gc.h: Use the PROTO macro when declaring functions.
5992 * gc.c: Use the PROTO macro when declaring static functions.
5993 Remove the CPP hair around function definitions.
5995 * gc.c (scm_init_storage): Initialize scm_asyncs.
5997 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5998 preprocessor symbol; "__scm.h" is where it might get #defined.
5999 * __scm.h: Similar: #include <scmconfig.h> before testing
6002 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6004 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6006 * init.c (scm_boot_guile): Add init_func argument; call
6007 (*init_func) instead of calling scm_appinit; it's ucky to
6008 hard-code names for the user's procedures.
6009 * init.h (scm_boot_guile): Adjust declaration.
6011 * __scm.h (PROTO): New macro, for declaring functions with
6014 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6015 eliminate all the __STDC__ conditionals.
6016 (scm_boot_guile): Add declaration.
6017 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6018 Remove __STDC__ conditionals around function definitions; the
6019 declarations in init.h will provide the same information, more
6022 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6023 complain about it in the error message; the error message is
6024 adequate without that note, and there's nothing the user can do
6027 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6029 * Makefile.in (ancillary): Drop def.sed.
6031 * posix.c (scm_init_posix): Use numeric values, rather than
6032 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6033 F_OK. The symbols aren't available on some systems, and I'm
6034 pretty sure their values are fixed by common widespread practice.
6035 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6037 More functions unavailable on some systems.
6038 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6039 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6041 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6042 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6043 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6044 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6045 stub that signals an error as the #else.
6047 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6049 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6051 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6053 * unif.c: include ramap.h.
6055 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6057 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6059 * ports.c: include sys/ioctl.h.
6061 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6063 * configure.in: check for sys/ioctl.h.
6065 * ports.c: include <malloc.h> not "malloc.h".
6067 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6069 * fports.c: remove ttyname and tmpnam declarations.
6071 * posix.c: fewer ttyname declarations.
6073 * fports.c: include <string.h> not "string.h".
6075 * init.c, ioext.c: include string.h and unistd.h.
6077 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6079 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6080 genio.c, simpos.c, vports.c: include string.h.
6082 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6084 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6086 (scm_addr_buffer_size): change type from scm_sizet to int.
6087 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6088 from scm_sizet to int.
6090 * error.c: include unistd.h.
6092 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6095 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6097 * __scm.hd, def.sed: deleted.
6099 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6101 Changes for NeXT, suggested by Robert Brown.
6102 * configure.in: Call AC_TYPE_MODE_T.
6103 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6104 NeXT. Put header file list in alphabetical order.
6105 * configure, scmconfig.h.in: Regenerated.
6106 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6108 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6111 * acconfig.h: New file, providing documentation for the CPP
6112 symbols defined in configure.in
6113 * acconfig-1.5.h: Removed; superceded by the above.
6115 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6117 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6119 * fports.c (scm_open_file): don't return #f, throw error.
6121 * ioext.c (fileno): renamed from %fileno.
6122 (soft-fileno): deleted.
6124 * ports.c (scm_port_revealed): don't need to check for -1 from
6126 (scm_set_port_revealed_x): return unspecified, not #f.
6128 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6130 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6132 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6134 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6136 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6138 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6139 This is necessary on Ultrix, and doesn't hurt portability.
6141 * Makefile.in (dist-dir): New target, implementing a new dist system.
6142 (installed_h_files): Put in alphabetical order.
6143 Remove duplicate entries for markers.h and unif.h.
6144 (c_files): Remove duplicate entries for markers.c.
6145 (ancillary): Renamed from anillery; all uses changed. Remove
6146 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6147 Remove all the ../doc/* files; doc/Makefile.in handles that.
6149 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6151 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6152 every if must have an else, or else the whole command has a
6153 non-zero exit code whenever the if's condition is false.
6155 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6157 * posix.c: include string.h.
6159 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6161 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6164 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6165 Remove leading % from scheme names.
6166 Do not return error values, call SCM_SYSERROR or similar.
6168 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6170 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6172 * struct.c (scm_init_struct): new file.
6174 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6176 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6177 (scm_list_head): added list-head for rapidly chopping argument
6178 lists off of longer lists (and similar).
6180 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6182 * objprop.c (scm_object_property): assq the cdr of the whash
6183 handle for obj, not the handle itself.
6185 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6187 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6188 weak hash tables last of all marking to avoid an obscure gc bug.
6189 WARNING: circular lists stored in a weak hash table will hose us.
6191 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6193 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6194 new functions similar to scm_substring_move_left_x and
6195 scm_substring_move_right_x.
6197 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6199 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6202 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6204 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6206 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6208 * strports.c (scm_strprint_obj): convenience function. C for
6209 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6211 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6212 removed to a separate library
6214 * init.c (scm_boot_guile): copied from guile-tcl.c.
6215 Initialization specific to tcl interpreters removed.
6217 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6219 * ports.c (scm_ports_prehistory): size malloced here doesn't
6220 matter so long as it is non-0 (got rid of "* 4").
6222 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6224 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6225 since its definition was bogus).
6227 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6229 * mallocs.[ch]: back again (for rx at least).
6231 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6233 * ports.c: removed functions relating to the mapping between ports
6234 and descriptors. (That stuff is unix-specific and should be collected
6235 in a separate library).
6237 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6238 (Tom Mckay@avanticorp.com)
6240 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6242 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6243 handled correctly (SCM_FREEP was applied to them) -- test for
6244 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6245 being overwritten with #f. (brown@grettir.bibliotech.com)
6247 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

6412 initialization to fix a race condition.
6414 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
