1 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
4 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
6 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
8 * stacks.c (read_frame): Bugfix: Removed lingering `else'
10 (read_frames): Use SCM_MACROEXPP.
12 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
14 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
15 don't contain interesting information since all arguments are
16 present in the frame which applies the compiled closure anyway.);
17 Skip the transformer application frames.
19 * print.c (scm_iprin1): Print gsubrs as primitives.
21 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
23 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
25 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
26 that we can identify these in a backtrace. (This change doesn't
27 introduce any significant speed penalty.)
29 * eval.c: Added note about `serial-map' using scm_map.
31 * read.c, read.h (scm_read_options, scm_read_opts): Removed
32 readline options. They should reside in their own options array.
34 * readline.c, readline.h (scm_readline_options,
35 scm_readline_opts): Moved readline options here.
37 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
39 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
40 SCM_ROCHARS instead of SCM_CHARS.
42 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
43 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
45 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
47 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
48 This is quite important since the latter clears the
49 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
50 every single character read...
52 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
54 * print.c (scm_iprin1): Removed suspect looking (and indeed
55 malevolent) semicolon after test for user supplied closure print
56 procedure. (Thanks to Telford Tendys.)
58 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
59 (scm_memq, scm_memv, scm_member): Do argument checking *before*
60 starting to search the list. Removed call to sloppy_mem_check.
62 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
63 procedures: Same as scm_delq_x et al, but delete maximally one
66 * options.c (scm_options, scm_init_options): GC-protect option
67 values of type SCM. (Thanks to Telford Tendys.)
69 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
71 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
72 make sure that there always is a "real" scm_lookupcar.
74 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
76 * read.c, read.h (history-length, history-file): New read options.
77 (scm_read_options): Stifle history to history length.
79 * readline.c (scm_read_history, scm_write_history): New
82 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
84 * eval.h (scm_macro_eval_x): Removed declaration.
86 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
87 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
88 Renamed and made global.
90 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
91 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
93 * evalext.c, evalext.h: New files. Contain non-R5RS things
94 having to do with evaluation.
96 * evalext.c (scm_serial_map): New procedure: Version of `map'
97 which guarantees that the procedure is applied to the lists in
99 (scm_m_sequence_to_list): New syntax: Version of `begin' which
100 returns a list of the results of the body forms instead of the
101 result of the last body form.
102 (scm_definedp, scm_m_undefine): Moved from eval.c
104 * evalext.h (scm_m_sequence_to_list): Added declaration.
106 * macros.c, macros.h: New files.
107 (scm_procedure_to_syntax, scm_procedure_to_macro,
108 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
109 scm_macro_name, scm_macro_transformer): Moved from eval.c
110 (scm_make_synt): Moved from eval.c
112 * procs.c, procs.h (scm_procedure_documentation): Moved from
115 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
118 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
120 * debug.c, print.c: Added #include "macros.h".
122 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
124 This change adds the ability to use `unread-char' multiple times
125 without interspersed reads and adds the new procedure
126 `unread-string'. The change is optimized for the common case of
127 unreading a single character. This is also the reason behind the
128 choice to store characters in the port itself: in most cases no
129 extra malloc is required.
131 The amount of code in some macros in ports.h has been increased to
132 the extent that they would fit better as C functions, but, since
133 this code belongs to the port representation, such functions
134 should be placed in ports.c which would cause calls back and forth
135 between ports.c and genio.c. That is not good for performance.
136 Also, keeping them as macros allows the compiler to do some
137 optimizations which are needed to make the current interface
138 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
140 One benchmark (Guile startup time) indicates an increase of
141 loading speed of 1%. Another (reading (using `read') boot-9.scm
142 10 times) shows no change in performance.
144 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
145 made to find a beautiful solution.)
147 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
148 (SCM_TRY_CLRDY): New macro: Only clear the first unread
149 character. (SCM_CLRDY clears all.)
150 (SCM_N_READY_CHARS): New macro: Returns number of unread
151 characters in a port. Returns wrong answer if SCM_CRDYP is false.
152 (struct scm_port_table): New fields: `entry' contains port table
153 index, `cp' points to last unread char, `cbuf' is the buffer for
154 unread chars, `cbufend' points after end of the character buffer.
156 * ports.h, ports.c (scm_unread_string): New procedure.
157 (scm_grow_port_cbuf): New function.
159 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
161 (scm_generic_fgets), fports.c (local_fgets): Use a loop
162 to read unread characters. Use SCM_TRY_CLRDY instead of
165 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
167 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
169 * genio.c, genio.h (scm_ungets): New function.
171 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
174 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
176 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
177 declarations. (Thanks to Russ McManus.)
179 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
181 * numbers.c (num2long): As a software archeologist, I'm proud of
182 this finding! :) Preliminary dating suggests an almost 4 year old
183 remnant from the SCM ancestor. The sample has been removed from
184 the finding site and is now safely stored in the repository.
186 * numbers.h: Removed prototype for num2long.
188 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
190 * gh_data.c (gh_scm2doubles): Make it possible to pass result
192 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
193 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
194 * gh.h: Updated and added prototypes.
196 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
198 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
200 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
202 * guile-snarf.in: Never generate an empty file. (Thanks to
205 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
206 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
207 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
208 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
209 gh_new_procedure5_0): Specify argument types, to appease C++
210 compilers. (Thanks to Brad Bowman.)
212 Bug reports from Russ McManus:
213 * guile-snarf.in: If the CPP environment variable is set, use that
214 as the C preprocessor, instead of the preprocessor autoconf
216 * snarf.h (SCM_PROC): Cast the function pointer passed to
217 scm_make_gsubr, to satisfy C++.
219 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
220 Use the handler passed, instead of ignoring it and using
221 gh_standard_handler. (Thanks to Etienne Bernard.)
223 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
225 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

248 * script.c (scm_compile_shell_switches): Define
249 use-emacs-interface in the root module, so the repl code can see
250 it. See today's change to top-repl in ice-9/boot-9.scm.
252 * filesys.c (set_element, get_element): Make sure that `element'
253 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
254 Boekemeier and Jorgen "forcer" Schaefer.)
256 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
258 * chars.c (scm_charnames): In ASCII character name table, make
259 newlines print as #\newline by default, not #\nl.
261 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
262 alphabetical order. Oh thrills. But it helps me know how far
263 along in the compilation I am.
264 * Makefile.in: Regenerated.
266 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
268 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
269 #bytes(...) to #y(...), and syntax for short vectors from
270 #short(...) to #h(...). This may seem nutty, but, like the other
271 uniform vectors, byte vectors and short vectors want to have the
272 same print and read syntax (and, more basic, want to have read
273 syntax!). Changing the read syntax to use multiple characters
274 after the hash sign breaks with the conventions used in R5RS and
275 the conventions used for the other uniform vectors. It also
276 introduces complexity in the current reader, both on the C and
277 Scheme levels. (The Right solution is probably to change the
278 syntax and prototypes for uniform vectors entirely.)
280 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
282 Don't use local_fgets on sockets; ftell doesn't work on sockets.
283 (Thanks to Jorgen "forcer" Schaefer.)
284 * ports.h (SCM_NOFTELL): New flag.
285 * fports.c (local_fgets): If it's set, use the generic fgets.
286 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
288 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
290 * script.c (scm_compile_shell_switches): Add handling of -q switch
291 (inhibit loading of user init file).
292 (scm_shell_usage): Add usage text for -q switch.
293 (scm_compile_shell_switches): Always load user init file first if
296 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
298 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
299 and is now broken under NetBSD. I can't fathom what it's trying
300 to do, so I've replaced it with something that I do understand,
301 which seems to work, and which isn't broken on NetBSD. "Progress?
302 You Decide." (Thanks to Perry Metzger.)
304 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
305 signed/unsigned comparison.
307 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
309 Warning fixes from Greg Harvey:
310 * unif.c (scm_array_set_x): initializer for pos
311 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
312 * struct.c (scm_struct_ref, scm_struct_set_x): Added
313 initializers for field_type, since EGCS so desparately wants to
315 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
316 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
317 when GUILE_DEBUG is defined.
318 * dynwind.h (scm_wind_chain): Same.
319 * ports.h (scm_pt_size, scm_pt_member): Same.
320 * print.h (scm_current_pstate): Same.
321 * procs.h (scm_make_cclo): Same.
323 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
325 Handle short and long long uniform arrays properly. (Thanks to
327 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
328 raeql_1): Add cases for scm_tc7_svect (short vectors) and
329 scm_tc7_llvect (long long vectors).
331 Change the way libguile and boot-9.scm are timestamped, to try to
332 get rid of these spurious mismatch warnings. Now both
333 libguile/versiondat.h and ice-9/version.scm are generated directly
334 by the configuration process, rather than having version.scm
335 generated directly, and libguile/versiondat.h generated by the
336 Makefile, which is generated by configure. It seems that
337 sometimes the Makefile would change, but versiondat.h depends on
338 Makefile.in, not Makefile, so it wouldn't get rebuilt.
339 * Makefile.am (versiondat.h): Target removed; this is generated
340 directly by the configure script now.
341 (BUILT_SOURCES): Remove versiondat.h.
342 * versiondat.h.in: New file, transformed by the configure script
344 * Makefile.in: Regenerated.
346 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
347 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
348 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
349 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
350 if we want to use them in a header file some day, we can. (Thanks
353 * stime.c (scm_get_internal_real_time): Do the arithmetic using
354 SCM numbers, so we won't have rollover problems; the range of a
355 signed long in milliseconds is about 25 days. (Thanks to Karl
358 Don't redefine sleep and usleep; fix this problem now.
359 * coop.c (sleep, usleep): Remove declarations; we don't use or
360 redefine these any more.
361 (scm_thread_usleep, scm_thread_sleep): New functions which do the
362 job of usleep and sleep in a thread-friendly way. We can use
363 these in the rest of Guile. Define versions for systems both with
365 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
366 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
367 we're just using it, not redefining it, we can use a K&R style
369 (sleep): Declare this, too, if the system hasn't.
370 (scm_sleep, scm_usleep): Use scm_thread_sleep and
371 scm_uthread_sleep if they're available; otherwise, just call the
373 * scmconfig.h.in: Regenerated.
375 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
377 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
379 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
381 * threads.c: Doc fix.
383 The argument type of usleep varies from system to system,
384 as does the return type. We really shouldn't be redefining usleep
385 at all, but I don't have time to clean that up before the 1.3.
386 release. It's on the schedule for afterwards. (Thanks to Julian
388 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
390 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
391 * scmconfig.h: Regenerated.
393 * simpos.c (scm_software_type): Procedure deleted. This isn't the
394 right way to handle system variation. Autoconf's approach is the
396 * simpos.h (scm_software_type): Declaration deleted.
398 * script.c (scm_find_executable): Don't test if unix is #defined
399 here; first, NetBSD doesn't #define it, and second, it's the wrong
400 way to go about these things. (Thanks to Perry Metzger.)
401 (dld_find_executable): Delete this MSDOS support code. This isn't
402 the way we want to support this; it needs to be rethunk at a
405 * genio.c (scm_do_read_line): Don't just politely check that the
406 line was either non-empty or EOF. Abort if it's empty and not
409 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
411 * scmconfig.h.in: Regenerated.
413 * libguile.h: Don't omit the dynamic linking functions. (Thanks
416 * genio.c (scm_do_read_line): Count lines correctly when the file
417 doesn't end in a newline.
419 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
421 * genio.c (scm_do_read_line): Maintain the line count correctly.
422 (Thanks to Harvey J. Stein and Greg Harvey.)
424 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
427 * numbers.c (big2str): Protect t from garbage collection until
428 we're done. (Thanks to Gary Houston.)
430 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
432 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
434 * Makefile.in: Regenerated.
436 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
437 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
440 Do magic to mix reads and writes on stdio FILE-based ports.
441 (Thanks to Christian Lynbech.)
442 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
444 (pre_read, pre_write): New functions.
445 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
446 local_fputs): Call them.
447 (local_fflush): Mark the port as ready for reading and writing.
448 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
449 flags on new port objects. This might not be accurate --- who
450 knows what state the FILE * is in when we get it --- but it won't
451 do extraneous calls to fflush or fseek, so it's no worse than the
452 behavior before this change.
453 * ports.h: Add comment.
455 Centralize the creation of port objects based on stdio FILE * in
456 fports.c; don't just throw them together anywhere.
457 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
458 what the rest of Guile wants. Don't set the revealed count;
459 that's only appropriate for stdin, stdout, stderr.
460 (scm_standard_stream_to_port): This function does set the revealed
462 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
463 not scm_stdio_to_port.
464 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
465 * fports.c (scm_open_file): Same.
466 * posix.c (scm_pipe): Same.
467 * socket.c (scm_sock_fd_to_port): Same.
468 * ioext.c (scm_fdopen): Same.
469 (scm_freopen): Moved from here to...
470 * fports.c (scm_freopen): ... here. This is really something that
471 munges the internals of an fport, so it should go here.
472 * fports.h (scm_stdio_to_port): Adjust prototype.
473 (scm_standard_stream_to_port, scm_freopen): New protoypes.
474 * ioext.h (scm_freopen): Prototype removed.
476 * filesys.c (set_element, get_element): This can work on both pipe
477 and file ports, so use SCM_FPORTP to typecheck, instead of testing
480 * scmconfig.h.in: Regenerated.
482 Change the definition of the functions in scm_ptobfuns so that
483 they get passed the port object, not the port's stream.
484 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
485 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
486 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
487 Pass the port itself to the scm_ptobs function.
488 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
489 scm_generic_fgets): Same.
490 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
491 getc_void_port, fgets_void_port, close_void_port): Just change the
492 argument names; these functions don't really do anything.
493 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
494 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
495 port as an argument, and use SCM_STREAM to get the stdio FILE *.
496 Also, use prototyped definitions, and get rid of the extra
498 (scm_fptob, scm_pipob): We don't need casts here any more.
499 * strports.c (prinstpt): Use prototype declarations.
500 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
501 and use SCM_STREAM to get the string info. Also, use prototyped
502 definitions, and get rid of the extra declarations.
503 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
506 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
507 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
509 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
510 scm_fgets, for consistency.
511 (scm_fptop, scm_pipob): References updated.
513 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
515 Include the source location in error messages for scripts.
516 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
517 stack is still there when we catch the error.
518 * throw.c (handler_message): If we are handling an error with a
519 message, then put together the proper arguments and call
520 scm_display_error, instead of scm_display_error_message. That
521 displays source location, if it can find it.
523 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
525 * gc.c (scm_unprotect_object): Change this so that calls to
526 scm_protect_object and scm_unprotect_object nest properly.
527 (scm_protect_object): Doc fixes.
529 * strings.c (scm_string_set_x): Require the argument to be a
530 writable string, not a substring or a symbol.
531 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
532 (Thanks to John Redford and Charbel Jacquin.)
534 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
536 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
538 * eval.c (safe_setjmp): Remove this misunderstanding.
539 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
542 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
544 * libguile.h: Mark these as C declarations, for compilation by C++
547 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
548 __cplusplus clause. I seriously doubt this ever worked the way
549 the author seems to have intended.
551 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
553 Utterly needless cleanups to hopelessly messy code.
554 * ports.c: Doc fixes.
555 (scm_fflush): Moved to ...
556 * genio.c (scm_fflush): ... here, amongst all the other port
557 method invocation functions.
558 * genio.h, ports.h: The prototype moves too.
560 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
562 * backtrace.c (display_error_body): The current frame does not
563 always have a parent frame; consider a function called directly
564 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
567 * alloca.c (alloca): Undo yesterday's changes, and simply call
568 malloc directly for storage, and abort if we don't get what we
569 want. The situation is much simpler --- just call malloc. Emacs
570 has bizarre/evil requirements (signal handlers might malloc unless
571 you set this global flag, so you have to set the flag around all
572 calls to malloc) which we are certainly not going to conform to,
573 so we can do the simple and obvious thing.
575 * coop.c (coop_condition_variable_wait): Make this function
576 static. It's only useful internally --- you should never just
577 wait on a condition variable.
578 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
580 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
582 * unif.c (scm_array_set_x): Accept any kind of number as an
583 element for a uniform vector of doubles. This is more consistent
584 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
586 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
587 works; I can't conveniently test it myself. (Thanks to Dvid
588 Tillman for the bug report.)
592 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
593 from here, not from scm_compile_shell_switches (which is a pretty
594 dumb place to do it).
595 (scm_load_startup_files): New function.
596 (scm_ice_9_already_loaded): Variable moved to here from script.c.
597 * script.c (scm_compile_shell_switches): Don't load the startup
599 (scm_ice_9_already_loaded): Variable moved.
600 * init.c (scm_load_startup_files): Prototype for new function.
601 * gh_init.c (gh_enter): Doc fix.
603 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
605 Some anti-warning changes from Greg Harvey.
606 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
607 warnings when it doesn't understand our NORETURN declarations in
609 * posix.c (scm_mknod): Similar.
611 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
613 * posix.c (scm_getpwuid): If we can't find an entry, return our
614 own message, instead of using scm_syserror --- the getpwMUMBLE
615 functions don't set `errno' to anything interesting.
617 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
619 Get rid of warnings from the cooperative threading system.
620 * threads.h (scm_single_thread_p, scm_yield,
621 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
622 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
623 scm_wait_condition_variable, scm_signal_condition_variable): Add
624 prototypes for these Scheme-visible functions.
625 * coop-defs.h (coop_next_runnable_thread,
626 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
627 Prototypes for these here, even though they're from iselect.c.
628 (coop_condition_variable_wait, coop_join): Add prototypes.
629 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
630 scm_threads_free_condvar): Make these smob functions static.
631 * coop-threads.h (coop_init): Give this a real prototype.
632 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
633 (coop_next_runnable_thread): No need to provide prototype; it's in
636 * scmconfig.h.in: .detarenegeR
638 * iselect.c, threads.c: Doc fixes.
640 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
642 * Makefile.in: Regenerated with a patched automake, to get
643 dependency generation right when using EGCS.
645 * inet_aton.c (inet_aton): Add prototype, to remove compiler
646 warning. (Thanks to Robert Pluim.)
648 * inet_aton.c (inet_aton): Reassure the compiler that the
649 arguments to the <ctype.h> macros are all unsigned characters, not
652 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
654 Getting rid of more warnings...
655 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
656 today's change to ../configure.in.
657 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
658 * scmconfig.h.in: Regenertaded.de.,.__
659 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
660 (scm_localtime, scm_mktime): Use a const char * to manipulate the
663 * readline.c: Doc fix.
664 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
665 * readline.h (scm_filename_completion_function): Add prototype.
666 (scm_init_readline): Make this into a prototype.
668 * readline.c (scm_filename_completion_function): Use SCM_PROC to
669 declare this, instead of calling scm_make_subr manually.
671 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
673 * readline.h (scm_init_readline): Add prototype for this.
674 (scm_init_readline): Make this a real prototype.
676 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
678 Warning fixes from Maciej Stachowiak:
679 * backtrace.h (scm_display_application, scm_backtrace): Add
681 * debug.c (scm_m_start_stack): Make this function static.
682 * fluids.h (scm_fluid_p): Add prototype.
683 * procprop.c (scm_i_procedure_arity): Make this function static.
684 * regex-posix.c (scm_regexp_error_msg): Make this function static.
685 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
686 * root.h (scm_dynamic_root): Add external prototype.
687 * scmsigs.h (scm_usleep): Add external prototype.
688 * script.h (scm_init_script): Use prototype, not K&R decl.
689 * stacks.h (scm_stack_id): Add external prototype.
690 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
692 1998-09-30 Mark Galassi <rosalia@cygnus.com>
694 * gh.h: took out the definitions of vset and vref, since they are
695 replaced by the proper vector routines that correspond to the R4RS
698 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
700 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
701 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
702 third argument, a C expression that should result in a SCM value,
703 which is used to initialize the variable. Reimplemented
704 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
707 * version.h (scm_libguile_config_stamp): Add prototype.
708 (From Maciej Stachowiak.)
710 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
712 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
713 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
715 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
717 * print.c (scm_iprin1): Rather than having one i, and using it in
718 several places, declare a fresh i local to each block where it is
719 used, and give it a signedness appropriate to its use in each case.
722 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
725 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
726 signed/unsigned clashes.
728 * posix.h (scm_tmpnam): Added prototype.
730 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
731 scm_make_subclass_object): Add external prototypes.
733 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
734 comparison is okay here.
736 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
738 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
739 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
741 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
744 * load.c (swap_port): Make this function static.
746 * load.c (scm_search_path): Make max_path_len and max_ext_len
747 unsigned, since they're compared against string sizes.
749 * load.c (init_build_info): Make i unsigned.
751 * ioext.h (scm_read_line): Add prototype.
753 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
754 scm_hash_fn_remove_x): Make hash bucket index local variable k
755 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
756 accurately as possible.
758 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
759 comparisons, and range checking to make sure those casts are
762 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
763 signed/unsigned comparisons.
765 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
766 avoid signed/unsigned comparisons.
767 * smob.h (scm_numsmob): Change extern declaration to match.
769 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
770 avoid signed/unsigned comparisons.
771 * ports.h (scm_numptob): Change extern declaration to match.
772 (scm_current_load_port, scm_set_port_line_x,
773 scm_set_port_column_x): New prototypes.
775 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
776 test code, and it causes warnings.
778 * gh.h (gh_int2scmb, gh_uniform_vector_length,
779 gh_uniform_vector_ref): Added prototypes.
781 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
782 debugging support unconditionally. That's backtrace.c, stack.c,
783 debug.c, and srcprop.c.
784 (EXTRA_libguile_la_SOURCES): Omit those from here.
785 * Makefile.in: Regenerated.
787 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
789 * options.c (scm_options): Bugfix: Allow empty list of options!
791 * debug.c, debug.h (scm_single_step): Removed.
792 (scm_with_traps): New procedure. This procedure could easily be
793 written in Scheme but needs to be highly optimized.
795 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
797 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
798 Check SCM_TRAPS_P before trapping.
800 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
802 Changes to avoid signed/unsigned comparison warnings.
803 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
804 (scm_gc_sweep): Make n and j local to the blocks they're used in,
805 so they can have appropriate types for each application. Make i
806 signed. Use initializers in some spots. I'll probably pay for
808 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
809 (scm_must_realloc): Make nm unsigned.
810 (init_heap_seg): Make new_seg_index and n_new_objects signed.
811 (scm_init_storage): Use prototype-style definition, and make the
813 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
814 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
816 * filesys.c (scm_readlink): Make local vars rv and size ints, to
817 avoid signed/unsigned comparison warnings, and because the return
818 value of readlink may be -1. Don't bother casting the third
819 argument to readlink.
821 * filesys.c (scm_dirname, scm_basename): Move these to their own
822 page, at the end of the file.
823 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
825 * eval.h (scm_eval_options_interface): Add external prototype for this.
826 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
828 * eval.c (scm_lookupcar1): Make this static.
830 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
831 Make these prototype declarations, not K&R-style.
833 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
834 unsigned comparison warning.
836 * appinit.c: File removed. It had a single function in it, empty,
837 whose reason for existence is explained in no documentation or
838 comment. I think it's there as a default for some Tcl-style
839 initialization, but Tcl abandoned that approach a while ago.
840 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
841 (BUILT_SOURCES): Remove appinit.x.
842 * Makefile.in: Regenerated.
844 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
846 * Makefile.in: Regenerated using the last public version of
847 automake, not the hacked Cygnus version.
849 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
851 Remove Totoro kludge.
852 * Makefile.in, scmconfig.h.in: Regenerated.
853 * init.c, readline.c: Don't check if TOTORO is #defined.
855 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
857 * Makefile.am: Adjust for new thread configuration system.
858 (INCLUDES): Include the value of THREAD_CPPFLAGS.
859 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
861 (THREAD_LIBS): Definition deleted; automake will generate such
862 things automatically.
863 * Makefile.in: Regenerated.
865 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
867 Simplify smob and port marking; set the mark bit in the generic
868 marking code, and make marker routines only responsible for
869 turning up outgoing pointers.
870 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
871 before calling the marking function. Don't call the marking
872 function if it's zero.
873 * markers.c (scm_mark0): Just return #f. This function isn't
874 necessary at all now, but it's harmless to call it. We'll leave
875 it in so other folks' code doesn't croak at link time.
876 (scm_markcdr): Don't call SCM_SETGC8MARK.
877 * async.c (mark_async): Don't call SCM_SETGC8MARK.
878 * dynl.c (mark_dynl_obj): Same.
879 * root.c (mark_root): Same.
880 * srcprop.c (marksrcprops): Same.
881 * unif.c (markra): Same.
882 * variable.c (scm_markvar): Same.
883 * ports.c (scm_markstream): Same.
884 (void_port_ptob): Specify zero for our marking function.
885 * debug.c (debugobjsmob): Same.
886 * dynwind.c (guardsmob): Same.
887 * filesys.c (dir_smob): Same.
888 * fluids.c (fluid_smob): Same.
889 * fports.c (scm_fptob, scm_pipob): Same.
890 * mallocs.c (mallocsmob): Same.
891 * regex-posix.c (regex_t_smob): Same.
892 * smob.c (freecell, flob, bigob): Same.
893 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
894 * throw.c (jbsmob, lazy_catch_funs): Same.
896 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
898 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
899 scm_copy_tree on code in order not to let memoized code to leak
900 out. Thus, scm_copy_tree needs to copy vectors as well since
901 quasiquote can introduce evaluated code also inside vector
904 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
906 * eval.c (scm_copy_tree): Removed ability to copy vectors.
908 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
909 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
912 * unif.c: Say that ivect and uvect are of type signed and unsigned
913 long instead of int in commentary so that it correctly describes
916 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
918 * stime.c: Removed declaration of strptime. (It should be
919 declared by the system headers. If it turns out that some systems
920 don't, we'll handle that then.) (Thanks to Greg Troxel.)
922 * stime.h: Renamed TIMEH --> STIMEH
924 * backtrace.c (scm_display_error, scm_display_backtrace): In order
925 to increase portability, don't use structure assignment.
926 (Thanks to Nicolas Neuss.)
928 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
930 (finalize_fd_sets): Added empty statement after last case label.
931 (Thanks to Nicolas Neuss.)
933 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
936 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
938 * init.c, readline.c: OK, I won't have these readline.x bug
939 reports anymore. We've had them since April. The current reason
940 is a completely unintelligible failure of totoro.red-bean.com to
941 do the test for rl_getc_function in libreadline correctly. This
942 kludge overrides the test if we're on totoro so that the snapshot
943 generation process can work.
945 * readline.c: Define a strdup replacement if not existent on system.
947 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
949 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
950 This change makes scm_make_vector R5RS compatible. We cannot keep
951 the third argument since people want to be able to deduce the form
952 of the C function call only by looking at R5RS. (At the same time
953 we have removed some unnecessary complexity!)
955 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
956 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
957 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
958 argument in call to scm_make_vector.
960 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
962 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
963 This macro is useful in applications.
965 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
967 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
968 (scm_parse_path, scm_search_path): New Scheme level procedures.
970 * load.h (scm_internal_parse_path, scm_parse_path,
971 scm_search_path): Declared.
973 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
975 * filesys.c (dirname, basename): New procedures.
977 * init.c (scm_boot_guile_1): Removed condition around
980 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
981 new data type (guards) for representation of C level guards and
982 data on the wind chain.
983 (scm_internal_dynamic_wind): New function.
985 * dynwind.h: Declare scm_internal_dynamic_wind.
987 * root.h (scm_root_state): Added scm_cur_loadp.
989 * root.c (mark_root): Added comment about cur_loadp.
991 * load.c: #include "dynwind.h";
992 (scm_primitive_load): Use scm_inner_dynamic_wind to update
995 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
997 * ports.c (current-load-port): New procedure.
999 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1001 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1002 not a tty, return #f.
1004 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1005 to Julian Satchell and Roland Kaufmann.)
1007 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1008 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1010 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1012 * debug.h, debug.c (scm_start_stack): New function. Implements
1013 the guts of old scm_m_start_stack.
1015 * debug.c (scm_m_start_stack): Use scm_start_stack.
1017 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1018 start_stack and restart_stack. (These have static scope.)
1020 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1022 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1023 readline functions to come in release 2.3. (Thanks to Chet
1025 (handle_errors): Use the above functions.
1027 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1029 * readline.c: Improvements for readline support: Handle errors
1030 better; Implement before-read-hook.
1032 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * init.c (scm_boot_guile_1), readline.c: Test for
1035 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1036 assure that we have version >= 2.1.)
1038 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1040 * readline.c (scm_readline): Defer interrupts while we're calling
1043 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1044 away the string to add_history.
1045 (completion_function): Do completion for readline. (Thanks to
1047 (scm_filename_completion_function): New procedure: Filename
1049 (current_input_getc): New function. Use this one instead of
1050 standard getc from readline.
1052 * throw.c, throw.h (scm_handle_by_throw): New function: This
1053 handler throws errors to next handler on the dynwind chain.
1055 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1057 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1060 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1062 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1064 (scm_procedure_properties): Modified to return arity together with
1066 (scm_procedure_property): Added the read-only property `arity'.
1067 (scm_set_procedure_property_x): It is an error to set the `arity'
1070 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1071 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1073 * procprop.h (scm_sym_arity): New symbol.
1075 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1076 to set the dispatch procedure of an operator or entity object.
1078 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1079 Made procedure slots read-only.
1081 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1082 scm_tcs_cons_gloc case in zero args switch; Fixed args
1083 construction for operators in scm_tcs_cons_gloc case in two args
1086 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1088 * fluids.c: Removed use of assert.h (in order to avoid
1091 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1093 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1095 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1096 change makes the evaluator safer at the cost of evaluation speed.
1097 It handles the case when the user has added a non-immediate
1098 improper end of the application form, e.g., `(+ 0 . x)'.
1099 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1100 minimize the extra cost as much as possible. The new code is
1101 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1102 problem with structs planted directly in the code (e.g. by a
1103 macro). This no longer causes segmentation fault. (Thanks to
1106 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1107 arg `proc' in order to be able to throw errors; New argument
1110 * Removed extra #include "debug.h"
1112 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1114 * scmsigs.c: Declare usleep as returning void on some systems.
1115 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1118 * coop.c (usleep): Return void on some systems.
1120 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1122 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1124 * coop.c: Changed return type of usleep to int.
1126 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1127 isn't found in the OS.
1129 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1130 isn't enabled. (Thought that I had made this change ages ago...)
1132 * iselect.c: Declare bzero if not defined by OS.
1134 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1136 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1137 condition. (Thanks to John Tobey.)
1139 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1140 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1143 * __scm.h: Start the long-term project of moving to POSIX threads.
1144 Phase 1: Classification of all critical sections.
1145 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1146 for A sections. (See comments in __scm.h for details.)
1148 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1149 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1151 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1153 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1154 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1155 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1156 dependencies on $(srcdir)/Makefile.in
1157 $(top_builddir)/config.status in order to avoid circularity.
1159 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1160 from argc if argc was 0 initially.
1162 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1163 in generation of libpath.h.
1165 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1167 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1168 libguile from 2 to 3.
1170 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1172 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1174 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1176 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1177 scm_set_port_column_x, scm_port_filename,
1178 scm_set_port_filename_x): Removed optional arguments. Added
1179 proper argument checking.
1181 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1182 stack size in machine words.
1184 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1185 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1186 to Ole Myren Röhne.)
1188 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1190 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1191 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1193 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1196 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1197 procedure apply: Copy argument lists before pushing them unto the
1198 environment so that the environment won't get mutated due to
1199 manipulation of procedure arguments. This should perhaps be
1200 regarded as a temporary solution until someone finds a more
1201 efficient one. (Thanks to Maciej Stachowiak.)
1203 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1205 * script.c (scm_compile_shell_switches): Use "guile" as default
1206 zero arg if argc is NULL.
1208 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1210 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1211 is zero. (Thanks to Dirk Herrmann.)
1213 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1215 * ports.c (scm_add_to_port_table): First line is now line 0
1216 (was 1). (Interface changed according to suggestion by Per
1219 * backtrace.c (display_header): Add 1 to line and column numbers
1220 when presenting them to the user.
1222 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1223 from debug.c --> eval.c
1225 * eval.h, eval.c (scm_eval_options_interface): New options
1227 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1228 i.e. stacks for new threads.
1230 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1232 * eval.c (unsafe_setjmp): Removed with #if 0.
1234 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1237 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1238 to avoid compiler warnings.
1240 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1242 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1244 * throw.c (handler_message): Print message on current error port
1245 instead of default error port. (Thanks to Maciej Stachowiak.)
1247 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1249 * ports.c (scm_add_to_port_table): allocate in units of
1250 struct scm_port_table *, not struct scm_port_table.
1251 * posix.c (scm_close_pipe): remove the port from the port table
1253 Thanks to Rob Engle for both fixes.
1255 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1257 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1258 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1260 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1262 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1264 * backtrace.c (display_error_body, display_backtrace_body),
1265 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1266 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1267 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1268 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1271 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1272 don't receive the jmpbuf arg anylonger.
1273 (scm_catch): Don't accept a #f tag.
1274 (scm_throw): Check that key is a symbol.
1275 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1277 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1279 * async.c (async_pending): Removed declaration.
1281 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1283 * dynwind.c (scm_wind_chain): New debug function.
1285 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1286 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1287 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1288 extra layer of functions around the body and handler of a thread.
1289 This extra layer makes sure that the handler is called in the
1290 dynamic context of the surround (= empty dynwind list), but under
1291 the *dynamic root* of the body. We can not use the dynamic root
1292 of the surround since that root belongs to another thread => stack
1293 is not handled correctly. It may seem ugly to use this extra
1294 layer, but the extra cost in terms of execution time is really
1295 negligible compared to the total amount of time required to create
1296 a thread, and it would reduce maintainability to duplicate the
1297 crucial and complicated steps performed by cwdr.
1299 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1300 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1301 get re-enabled. The important effect of this is that interrupts
1302 are blocked during thread switching so that thread data structures
1303 don't risk getting messed up by an unfortunate signal.
1304 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1305 seems to do more aggressive optimization which actually move
1306 instructions around in these macros in a fatal way. Therefore:
1307 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1308 just superstitious...)
1309 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1310 This macro should be used instead of SCM_ASYNC_TICK since the
1311 latter doesn't do context switches any more.
1313 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1314 instead of SCM_ASYNC_TICK.
1316 * coop.c, iselect.c: Since thread switches are now performed with
1317 interrupts masked, we can't use the old mechanism of delivering
1318 signals immediately when they arrive. Signals must instead be
1319 delivered when the asyncs run *after* the end of the critical
1320 section in scm_internal_select. But this also means after context
1321 switch so that the signal will be delivered to a different thread.
1322 To avoid this, I have changed the protocol of
1323 coop_wait_for_runnable_thread and friends so that they are allowed
1324 to return the original thread. So, if a signal arrives during
1325 scm_internal_select, we won't any longer be forced do a context
1326 switch, but can remain in the same thread and deliver the signal
1329 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1330 scm_asyncs_pending and made it global.
1332 * iselect.c: Small fixes.
1334 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1335 coop_condition_variable_init, coop_condition_variable_wait,
1336 coop_condition_variable_signal): Changed return type from `void'
1337 to `int'. This is to adhere closer to the pthreads interface.
1338 This, in turn, is part of an attempt to provide C versions of the
1339 mutex and condition variable primitives which can be part of a
1340 frontend to COOP or pthreads.
1342 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1343 coop_condition_variable_destroy): New functions.
1345 * coop-threads.c (scm_wait_condition_variable): Use
1346 coop_condition_variable_wait_mutex.
1348 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1349 Definitions moved to coop-defs.h.
1351 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1352 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1353 scm_cond_destroy): New C interface to mutecis and cond vars.
1355 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1357 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1359 * iselect.c: Now several threads can wait on the same file
1360 descriptor. The behaviour is compatible with OS select: All
1361 threads waiting for the fd return with the same status.
1363 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1366 Can spawn a thread from application C code.
1368 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1370 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1371 gh_doubles2scm): New functions.
1373 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1375 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1376 commented-out version of gh_eval_str()
1378 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1380 * socket.c (scm_bind): free soka after use.
1382 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1384 * stime.c (tzvar): new variable.
1385 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1386 avoid memory leaks when allocating.
1388 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1390 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1393 * gc.c, tags.h: Doc fixes.
1395 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1397 * eval.c (macro-eval!): Removed. This function was a design bug.
1398 It allowed memoized code to leak out to the scheme level. Most
1399 things that you could do with `macro-eval!' can be done with
1402 1997-12-20 Tim Pierce <twp@skepsis.com>
1404 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1405 scm_fgets now depends on ftell(3) to know how many bytes were
1408 1997-12-15 Tim Pierce <twp@skepsis.com>
1410 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1411 dealing with strings.
1413 1997-12-13 Tim Pierce <twp@skepsis.com>
1415 Make %read-line more suitable for implementing read-line efficiently.
1416 * ioext.c (scm_read_line): Strip the terminating newline from a
1417 string, and return a cons of the string and its terminator.
1419 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1420 of the string that is read is stored in this memory location.
1421 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1422 * genio.c, genio.h (scm_do_read_line): Update caller.
1423 * ports.h (scm_ptobfuns): Update typedef.
1424 * fports.c (scm_fptob, scm_pipob): Update struct.
1426 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1428 * filesys.c (set_element): Return file descriptor.
1429 (fill_select_type): Return the highest file descriptor.
1430 (scm_select): Tell select about the highest file descriptor. On
1431 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1432 Therefore the extra overhead for calculating the maximum fd seems
1433 to be more than compensated. Is this correct? In any case,
1434 scm_internal_select will be much faster with this info.
1435 (scm_select, fill_select_type, set_element): Don't accept any kind
1436 of object in the file descriptor list or vector.
1438 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1440 * iselect.c (finalize_fd_sets): Bugfix.
1442 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1444 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1445 when using scm_internal_select (since we might switch to another
1448 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1450 * simpos.c (scm_system): always define: use sysmissing if not
1451 available. Check for HAVE_SYSTEM instead of _Windows (does
1452 Windows lack system or does it have an unusable one?).
1453 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1454 Let the argument be optional: if not supplied, call system(NULL).
1456 * ports.c (scm_close_port): relax the type check from OPPORTP to
1457 PORTP; closing a closed port is allowed.
1459 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1461 * fports.c (scm_fgets): Return if the last char in a chunk is
1462 newline. When fgets returns a string whose length is `size-1', it
1463 is ambiguous whether a whole line was retrieved, so we must check
1464 explicitly whether a line terminator is present.
1466 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1468 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1469 before taking the CDR. (Thanks to Harald Meland.)
1471 * filesys.c (scm_stat): Slightly optimized.
1473 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1475 * ports.c (scm_close_port): Make sure the port is open before
1478 * guile-snarf.in: Pass args through to gcc in a way that preserves
1479 whitespace boundaries. (Thanks to Greg Badros.)
1481 1997-12-02 Tim Pierce <twp@skepsis.com>
1483 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1484 statement. (Thanks to Doug Evans for pointing this out.)
1486 1997-12-01 Tim Pierce <twp@skepsis.com>
1488 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1490 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1492 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1493 errno macro expansion of this field name. (errno is a C
1494 preprocessor macro on some systems.)
1496 1997-11-29 Tim Pierce <twp@skepsis.com>
1498 * iselect.c: Doc fix.
1500 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1502 * init.c (scm_start_stack): Removed initialization of
1503 scm_the_last_stack_var.
1505 * backtrace.h: Declare scm_the_last_stack_var.
1507 * backtrace.c: Define scm_the_last_stack_var.
1509 * root.c (mark_root): Don't mark the_last_stack_var.
1511 * root.h (scm_root_state): Removed the_last_stack_var.
1513 * throw.c: Added #include "fluids.h"
1514 (ss_handler): `the-last-stack' is now a fluid.
1516 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1517 --> the_last_stack_fluid.
1519 * backtrace.c: Added #include "fluids.h"
1520 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1521 (scm_backtrace): `the-last-stack' is now a fluid.
1523 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1524 after scm_init_fluids.
1526 1997-11-28 Tim Pierce <twp@skepsis.com>
1528 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1530 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1531 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1533 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1535 * iselect.c (coop_next_runnable_thread,
1536 coop_wait_for_runnable_thread): Disable interrupts so that no
1537 async is executed before a potential error_revive.
1538 (scm_internal_select): Disable interrupts during the parts of the
1539 code which manipulate the sleep queue and the file descriptors.
1541 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1543 * Makefile.am: Added iselect.c and iselect.h.
1545 * coop.c (coop_qinit): Initialize fields used by
1546 scm_internal_select.
1547 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1548 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1549 replacement in iselect.c.
1550 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1551 coop_join): If GUILE_ISELECT enabled, use
1552 coop_wait_for_runnable_thread instead of
1553 coop_next_runnable_thread.
1554 (usleep, sleep): New replacements for system functions if
1555 GUILE_ISELECT is enabled.
1557 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1559 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1561 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1562 iselect.h. Implement Scheme level `select' using
1563 scm_internal_select. (See NEWS.)
1565 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1567 * init.c: Call scm_init_iselect.
1569 * iselect.h, iselect.c: New files. Implements
1570 scm_internal_select. (See NEWS.)
1572 1997-11-27 Tim Pierce <twp@skepsis.com>
1574 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1575 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1576 and scm_must_free, since ultimately the string returned will be copied
1577 by scm_makfrom0str anyway. Also, read any characters that may have
1578 been pushed onto the port with scm_ungetc.
1579 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1580 * ioext.c (scm_read_line): Free string after Guilifying it.

1589 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1591 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1592 gh_repl (argc, argv).
1594 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1596 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1597 and to invoke scm_shell().
1598 (gh_launch_pad): took out the loading of boot-9.scm from here,
1599 since it is probably best to let the user control that. In fact,
1600 gh_repl() now invokes scm_shell() which does that.
1602 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1604 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1607 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

1621 (gh_uniform_vector_ref): started implementing the uniform types in
1624 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1626 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1627 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1629 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1631 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1632 configure.in was changed).
1634 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1636 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1637 * Makefile.in: Regenerated.
1639 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1641 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1642 OPORT is an `open' port, not an output port.
1644 * filesys.c (scm_close, set_element, get_element, scm_chown,
1645 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1646 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

1649 scm_port_column, scm_set_port_column_x, scm_port_filename,
1650 scm_set_port_filename_x, scm_port_mode,
1651 scm_close_all_ports_except, scm_set_current_output_port,
1652 scm_set_current_error_port): Likewise
1653 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1654 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1656 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1657 * backtrace.c (display_backtrace_body): Likewise
1658 * fports (scm_setvbuf): Likewise
1659 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1662 * unif.c (scm_uniform_array_write): Likewise
1664 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1666 Minor problems with substring-related tag changes.
1667 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1668 exactly what we want to leave in to detect substrings.
1669 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1670 * tags.h: Fix diagrams and comments describing the S tag bit;
1671 remove vestigial remarks about the D tag bit.
1672 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1673 * strings.c: Formatting tweaks.
1675 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1676 variable first; then SCHEME_LOAD_PATH, with a warning message.
1677 (scm_parse_path): New function.
1678 * script.c: Doc fixes.
1680 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1682 Readline support, from Daniel Risacher.
1683 * readline.c, readline.h: New files.
1684 * init.c: #include "readline.h".
1685 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1686 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1687 * Makefile.in: Regenerated.
1688 * scmconfig.h.in: Regenerated, after change to ../configure.
1690 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1692 * gh.h: gh_vector_set -> gh_vector_set_x
1694 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1696 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1697 with the ! -> _x mapping when going from Scheme to C.
1699 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1701 * gh.h (gh_reverse):
1709 (gh_assoc): added these gh_ functions implemented as macros.
1711 * gh_predicates.c (gh_null_p):
1712 (gh_string_equal_p): added these two missing predicates.
1714 * gh_list.c (gh_append):
1719 (gh_set_cdr_x): added these routines as I go through and try to
1720 complete the picture R4RS functions that should be mirrored in the
1723 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1725 * tags.h (scm_tc7_substring): Changed the comment and code to
1726 conform with the changes below. Folks! We have suddenly two new
1727 free tc7 codes!!! Jummy, jummy!
1729 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1731 * Makefile.in: Rebuilt.

1752 (scm_tc7_mb_string): Removed.
1753 (scm_tc7_mb_substring): Removed.

1756 Don't include "mbstrings.h".
1757 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1758 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1760 Don't include "mbstrings.h".
1761 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1762 (SCM_SYMBOL_SLOTS): Define as 4.

1764 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1765 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1766 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1767 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1787 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1789 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1791 * gh_test_c.c (c_vector_test): some improvements on the vector
1794 * gh.h (gh_vector): this used to exist but do the wrong thing.
1795 Now it (almost) does the right thing, though it takes a list
1796 instead of the individual arguments. I need to see how it could
1798 (gh_list_to_vector): added this function as a macro. Corresponds
1799 to Scheme's (list->vector ...).
1800 (gh_vector_to_list): added this function as a macro. Corresponds
1801 to Scheme's (vector->list ...).
1803 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1804 gh_vector_ref, so that it resembles the Scheme routines more.
1805 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1806 resembles the Scheme routines more.
1807 (gh_make_vector): this used to be (stupidly) called gh_vector().
1808 This is the right name, since it does the same thing as the Scheme
1809 (make-vector ...) procedure.
1811 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1813 * ports.h: #include "libguile/print.h"

1816 Some indentation fixes.
1818 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1819 longer a user field; New field: class_flags.
1821 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1823 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

1826 gh_int2scmb(), which is now tagged as obsolete.
1828 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1830 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1831 macros should by convention not test for NIMPness.)
1832 (SCM_COERCE_OPORT): Adjust indentation.
1834 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1835 SCM_NIMP test before SCM_PRINT_STATE_P.
1837 * struct.c, struct.h, gc.c: Renamed:
1838 scm_struct_i_layout --> scm_vtable_index_layout
1839 scm_struct_i_vcell --> scm_vtable_index_vcell

1841 scm_struct_i_printer --> scm_vtable_index_printer
1842 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1844 * struct.c (scm_print_struct): Use new printer slot; Default
1845 printing: Also output hex code of vtable so that type identity
1846 will be indicated as well.
1847 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1848 Removed struct_printer_var; Removed struct-vtable-offset;
1849 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1850 vtable-offset-user): New constants.
1852 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1855 the type represented by this vtable.
1857 * print.c (scm_iprin1): Don't print arguments of macro
1858 transformers. (They are always: exp env.); Bugfix: Unmemoize
1859 transformer source with correct environment.
1861 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1863 Streamlining of call-with-dynamic-root:

1866 there is now only one catch.
1867 (cwdr_outer_body): Removed.
1868 (cwdr_handler): New function.
1869 (scm_internal_cwdr): New function to perform the function of cwdr
1870 but take args that are more useful to C code. Also, the handler
1871 is now invoked *outside* of the new dynamic root, like the docs
1872 say. We no longer have to catch absolutely all errors, the caller
1873 is responsible for using a handler that does not throw, if he
1875 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1876 * root.h (scm_internal_cwdr): New prototype.
1878 Even more but risky streamlining:
1880 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1881 allocation of the jumpbuf of a root continuation. The changes
1882 below are controlled by it. They are now deactivated.
1883 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1884 the JMPBUF of the scm_rootcont to NULL before returning.
1886 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1887 when they are non-NULL.
1888 (scm_gc_mark): Likewise, mark only when non-NULL.
1890 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1891 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1893 * gc.c (scm_done_malloc): New function.
1894 gc.h (scm_done_malloc): New prototype.
1896 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1903 a certain value is acceptable as a port argument.
1904 (scm_print_state_vtable): New variable.
1905 (scm_free_print_state): Set `revealed' field to false.
1906 (scm_iprin1): Call user supplied closure printer with
1907 scm_printer_apply. Print in the traditional way when there isn't
1908 one or when it returns #f.
1909 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1910 Accept a port/print-state pair in addition to just a port.
1911 (scm_prin1): Don't return the print_state to the pool when it has
1913 (scm_printer_apply): Set `revealed' field of print_state to true.
1914 (scm_init_print): Set scm_print_state_vtable.
1915 (print_state_fluid, print_state_fluid_num): Removed.
1917 * throw.h (scm_handle_by_proc_catching_all): New prototype
1918 throw.c (scm_handle_by_proc_catching_all): New function
1920 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1922 * Makefile.in: Regenerated with automake 1.2c.
1924 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1926 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1927 was looping endlessly.
1929 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1931 * strports.c (scm_eval_string): Don't close the port.
1933 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1934 former returns a nice normal integer. (Thanks to Daniel
1937 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1939 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1940 makefile variable as a build parameter called LIBS. The
1941 build-guile program will use this, for the time being.
1942 * Makefile.in: Regenerated.
1944 Thanks to Shiro Kawai:
1945 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1946 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1949 * Makefile.in: Regenerated with automake 1.2a.
1951 * script.c (scm_compile_shell_switches): If we hit the -c or --
1952 arguments, don't set the car of (command-line) to scm_usage_name,
1953 the prettified name of the guile executable; give it the full
1954 path, the way shells usually handle $0.
1956 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1958 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1959 Scheme-level name `array-map' and renamed `serial-array-map' to
1960 `serial-array-map!'.
1962 * backtrace.c: Introduced exception handlers which now enclose
1963 `display-error' and `display-backtrace' so that error reporting
1964 won't get into infinite loops if an error occurs during displaying
1965 of the error. This can very easily happen with user supplied
1966 print call-back routines.
1968 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1970 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1971 the names `serial-array-map' and `array-map' should be removed.)
1973 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1975 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1976 Added #include "objects.h"
1978 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1979 Add #include "feature.h".
1981 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1982 (modinclude_HEADERS): Added objects.h.
1984 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1985 This test is needed at many places in the code and should be
1986 abstracted. (Motivated by the need of this test in libguiletk.)
1988 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1989 (scm_eval_string), load.c (scm_primitive_load,
1990 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1991 Use SCM_EOF_OBJECT_P.
1993 * eval.c (scm_init_eval): Add feature `delay'.
1995 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1997 * scmhob.h: Removed.
1999 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2001 * list.h (SCM_LISTn): New macros. Make list creation in C code
2002 prettier. The idea comes from STk.
2004 * sequences.h, sequences.c, append.h, append.c: Removed. These
2005 files implemented non-R4RS operations which would encourage
2006 non-portable programming style and less easy-to-read code.
2008 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2011 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2012 sequences.h, #include append.h.
2014 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2017 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2019 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2021 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2023 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2025 * eval.c: Added #include "objects.h"
2027 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2030 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2031 adjacent smob numbers.
2033 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2035 * procprop.h: Added declaration of scm_i_inner_name.
2037 * gsubr.c: New global symbol scm_i_inner_name.
2039 * debug.c (scm_procedure_name): Try procedure property
2040 `inner-name' if `name' fails.
2042 * print.c (scm_iprin1): Use scm_macro_name.
2044 * eval.c (scm_m_define): Give names to macros as well; Only the
2045 first top-level definition gives a procedure/macro a name.
2046 Otherwise confusing names can turn up in backtraces.
2047 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2048 `name'; Give names to macros as well.
2050 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2051 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2054 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2056 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2058 (prinmacro): Removed. The code has been moved/merged into print.c
2059 in order to decrease code redundancy. We want macros to print in
2060 a way equivalent to procedures, and it would be silly to duplicate
2061 the required code. (We don't want to maintain two places.)
2062 (macrosmob): Print field is now a NULL pointer.
2064 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2065 scm_macro_transformer): New prototypes.
2066 (scm_tc16_macro): Declared.
2068 * print.c (scm_iprin1): Added code for printing of macros. Macros
2069 are now printed in a way equivalent to procedures.
2071 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2073 * procs.h (scm_closure_p): Added declaration.
2075 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2077 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2078 Shouldn't pass "heap" as the subr name.
2080 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2082 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2083 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2084 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2085 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2086 SCM_BOOL_T. Any non-false value is true.
2088 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2090 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2091 scm_gensym): Added prototypes.
2093 * symbols.c (scm_gensym): New function. This will speed up
2094 certain types of applications (such as macro systems) which
2095 generate lots of symbols.
2097 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2099 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2101 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2103 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2104 specifier, since (2) or (2 . 3) would cause SEGV.
2105 (scm_transpose_array): more argument checking fixes.
2107 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2109 * Makefile.in: Regenerated.
2111 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2113 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2115 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2117 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2119 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2121 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2122 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2125 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2126 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2127 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2128 scm_array_p, scm_array_rank, scm_array_dimensions,
2129 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2130 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2131 scm_array_prototype): Added case scm_tc7_wvect.
2133 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2135 * errno.h: prototype for scm_strerror.
2136 * error.c (scm_strerror): new procedure.
2138 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2140 * list.c (scm_list_append_x): Allow non-pair as last argument.
2141 This is consistent with the R4RS append and is probably the
2142 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2144 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2146 * stime.h: prototype for scm_times.
2147 * stime.c (scm_times): new procedure.
2148 * ioext.c (scm_fseek): if the first argument is a file descriptor
2150 (scm_ftell): if the first argument is a file descriptor call lseek
2152 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2153 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2155 (scm_chown): if the first argument is a port or file descriptor,
2157 (scm_truncate_file): new procedure.
2158 Add DEFER/ALLOW INTS to a few other procedures.
2159 (scm_fsync): new procedure.
2160 (scm_open_fdes): new procedure.
2161 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2163 (scm_fcntl): the first argument can now be a file descriptor. The
2164 third argument is now optional.
2166 * posix.c (scm_execl, scm_execlp): make the filename argument
2167 compulsory, since omitting it causes SEGV.
2168 (scm_sync): return unspecified instead of #f.
2169 (scm_execle): new procedure.
2170 (environ_list_to_c): new procedure.
2171 (scm_environ): use environ_list_to_c. disable interrupts.
2172 (scm_convert_exec_args): take pos and subr arguments and
2173 improve error checking.
2175 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2177 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2178 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2179 argument to SCM_ASSERT. Furthermore, the name of the function
2180 should be passed as first argument when signalling
2181 SCM_WNA. (Thanks to Thomas Morgan)
2183 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2184 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2185 dispatches on the number of actual args has a default case
2186 reporting an internal error. This is a vestige from a version
2187 that mallocated a SCM vector to hold the arguments. In the
2188 current version this check is too late: if it ever happens we will
2189 have already overstepped the bounds of the array.
2191 Also, the patch [...] adds a check for too many actual arguments."
2193 mdj: Removed check for "internal programming error".
2195 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2197 * gh_io.c (gh_write): New function.
2199 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2200 throw.c (scm_internal_stack_catch): New sibling to the other catch
2201 functions. Code moved from gh_eval.c.
2202 throw.h: Added header.
2203 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2204 scm_internal_stack_catch.
2206 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2208 * ioext.h: fix up prototypes.
2209 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2210 Scheme name is now dup->fdes.
2211 (scm_dup_to_fdes): make the second argument optional and
2212 fold in the functionality of scm_primitive_dup.
2213 (scm_primitive_dup): deleted.
2215 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2217 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2218 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2219 ultrix are defined. Use setvbuf instead of setbuf.
2220 (scm_setvbuf): new procedure.
2221 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2222 (scm_setfileno): moved from ioext.c.
2223 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2224 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

2234 state as nested data while they are printed.
2235 (print_state_fluid, print_state_fluid_num): New variables.
2236 (scm_init_print): Initialize them.
2237 (scm_iprin): If print_state_fluid carries a print_state, use that
2238 instead of creating a new one.
2239 (scm_printer_apply, apply_stub, struct apply_data): New
2240 definitions to help with calling printer functions written in
2242 * print.h (scm_printer_apply): New prototype.
2244 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2245 user defined struct printer.

2255 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2256 SCM_ASSERT: arg comes before pos.
2258 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2260 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2261 to a list of length zero correctly.
2263 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2279 * ioext.h: removed scm_duplicate_port prototype.
2281 * ioext.c (scm_primitive_dup2): return the new file descriptor
2282 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2284 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2285 stream has been set.
2286 (scm_duplicate_port): deleted, there's now an implementation in
2288 (scm_primitive_dup2): do nothing if newfd == oldfd.
2290 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2292 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2296 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2298 * fluids.c (next_fluid_num): don't do
2299 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2301 * ports.h: prototypes too.
2302 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2304 * fports.h: prototype too.
2305 * fports.c (scm_evict_ports): moved from ioext.c.
2307 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2314 and ports (scsh compatible).
2316 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2319 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2321 * fluids.c, fluid.h: New files.

2332 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2333 unique for the new root when it has a parent.
2335 * smob.h: Include "libguile/print.h" to make scm_print_state
2338 * dynl.c (free_dynl_obj): New function to free the dynamic object
2339 data. (dynl_smob): Use it.
2340 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2341 the dynamic object data below the linking of the object to avoid
2342 memory leak when the linking code throws an error. Now the code
2343 leaks a whole dynamically linked library when must_malloc throws,
2344 but that should be much less likely.
2346 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2348 Changes to compile under gnu-win32, from Marcus Daniels:
2349 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2350 (scm_localtime): Change SCM_EOF to SCM_EOL.
2351 (scm_mktime): Likewise.
2352 * socket.c: Don't include sys/un.h unless autoconf tells
2353 us Unix domain sockets are available.

2355 (scm_addr_vector): Likewise.
2356 (scm_init_addr_buffer): Likewise.

2364 (scm_setpwent): For setpwent.
2365 (scm_setegid): For setegid.
2366 * net_db.c (scm_inet_netof): Don't include unless support

2382 scm_misc_error, not SCM_EOF.
2384 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2385 arguments for formatting the error message, not SCM_BOOL_F. I
2386 think this is left over from the (eq? '() #f) days.
2388 * read.c (recsexpr): Give this a dummy definition if
2389 DEBUG_EXTENSIONS isn't #defined.
2391 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2393 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2403 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2404 alloca.lo will be included in @LIBLOBJS@. Something better than
2405 this should be possible.
2406 * Makefile.in: Regenerated.
2408 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2410 * simpos.h: prototype for scm_primitive_exit.
2411 * simpos.c (scm_primitive_exit): new procedure, terminates the
2412 process without unwinding the stack.
2414 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2416 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2417 argument and logior its components together, so the user doesn't
2418 have to do this explicitly. Also, if regexp/basic is supplied, then
2419 turn off REG_EXTENDED.
2420 (scm_init_regex_posix): New regexp/basic symbol.
2421 (REG_BASIC): #define this if it is not already present.
2423 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2434 years in usage message.
2436 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2437 * Makefile.in: Regenerated.
2439 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2440 flag; I don't think we support it.
2441 (scm_make_regexp): Make sure the user doesn't pass the
2444 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2446 (scm_init_regex_posix): Define constants for the REG_mumble flags;

2454 Makefile directory variables. Print a message, but don't print
2456 (versiondat.h): Print a message, but don't print all the commands.
2457 * load.c: #include "alist.h".
2458 (init_build_info): New function.
2459 (scm_init_load): Call it.

2464 * root.c: Establish a reliable catch-all handler for the new root.
2465 After all the Scheme handler function might signal an error too,
2466 and we don't want to lose that.
2467 (cwdr_inner_body): Renamed from cwdr_body.
2468 (cwdr_outer_body): New function, to establish the user's handler,
2469 and pass control to cwdr_inner_body.
2470 (cwdr): Establish the reliable catch-all handler here, and pass
2471 control to cwdr_outer_body.
2472 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2473 the user's handler through to cwdr_outer_body.
2474 * throw.c (scm_handle_by_message): Move guts into....
2475 (handler_message): New static function.
2476 (scm_handle_by_message_noexit): New function.
2477 * throw.h (scm_handle_by_message_noexit): New prototype.
2479 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2480 across this. Only works on GCC. Otherwise, we hope for the best.
2481 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2482 the feeling that real thread systems will not need this...
2484 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2486 Try to detect when people are using one version of libguile and a
2487 different version of ice-9. People have been skewing things and
2488 sending in bug reports.
2489 * Makefile.am (versiondat.h): New file to generate.
2490 * version.c: #include "versiondat.h", to get version info.
2491 (scm_libguile_config_stamp): New function.
2492 * script.c: #include "version.h".
2493 (scm_compile_switches): Call scm_version to get version number.
2494 * scmconfig.h.in, Makefile.in: Regenerated.
2495 * Makefile.in: Regenerated.
2497 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2498 primitive definitions under their Scheme names.
2500 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2501 1:2. Helps avoid confusion between installed and uninstalled libs.
2503 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2506 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2507 backslash from definition; this should be used like: GDB_INTERFACE;
2509 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2511 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2512 new port unbuffered until its stream has been set.
2514 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2516 * ports.h: new prototype.
2517 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2519 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2521 Make things compile neatly under Sun's C compiler.
2522 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2523 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2524 unsigned, because that's what the ANSI function takes.
2525 * extchrs.h (xmbtowc): Corresponding change to prototype.
2526 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2528 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2529 argument plain char *.
2530 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2532 * tag.c (scm_tag): Remove unreachable statement.
2533 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2534 top of the word, it should be unsigned.
2536 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2537 is defined, to avoid warnings; it's only used in the
2538 conflict-checking code. Which might go away anyway.
2539 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2540 conditionals; put the label definition in an #if too, to stifle
2543 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2544 ChangeLog-threads in the distribution.
2545 * Makefile.in: Regenerated.
2547 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2549 * guile-snarf.in: Changed regexp to support CPPs that insert
2550 whitespace between lexical tokens (which munges the `%%%' snarf
2553 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2555 * load.c (scm_init_load_path): Append $(datadir)/guile to
2556 %load-path, so modules do not have to be installed in Guile's
2557 current version directory.
2559 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2561 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2562 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2563 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2564 call the sysdep functions with deferred ints.
2565 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2566 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2567 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2570 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2573 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2575 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2577 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2579 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2582 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2584 * eval.c (scm_lookupcar1): New procedure to cope with a race
2585 condition during lookup (when using threads).
2586 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2587 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2590 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2592 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2593 supplied. (Change from Tim Pierce.)
2595 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2597 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2598 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2599 default and not `()'. `#f' is the canonical non-value in Scheme,
2602 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2604 * struct.c (struct_printer): New variable that holds a handle on
2605 the Scheme variable *struct-printer*. This variable can be set by
2606 Scheme code to override the printing of structures.
2607 (scm_print_struct): If struct_printer is set, call it. If it is
2608 not set, or returns #f, print the structure in the old fashion.
2609 Include "eval.h" for scm_apply.
2611 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2613 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2614 scm_struct_i_n_words to get the number of fields, not
2615 -scm_struct_n_extra_words.
2617 On the route to fancier struct printing:
2618 * struct.c (scm_print_struct): New function to print a structure.
2619 Include "genio.h" to support it. This function doesn't do
2620 anything interesting right now, but I think it should be here
2622 * struct.h: Include "print.h" and add prototype for
2624 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2625 print structures ourself.
2627 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2629 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2630 before applying the handler in case it doesn't return.
2632 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2634 * scmsigs.h, async.h: updated.
2636 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2639 * posix.c (scm_uname): interpret only negative values as an error.
2640 Solaris normally returns a positive value.
2642 * script.c (scm_compile_shell_switches): if we are not going into
2643 an interactive repl, set scm_mask_ints to zero so that asyncs can
2646 * simpos.c (scm_system): don't ignore/unignore signals around
2649 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2652 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2653 done in boot-9.scm instead.
2655 * scmsigs.c, async.c: Major rewriting of signal handling code.
2656 (scm_sigaction): new procedure.
2657 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2659 (scm_raise): return unspecified, throw error on failure.
2661 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2663 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2664 feature, to help boot-9.scm decide whether to import the regex
2667 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2669 * eval.c: Include scmconfig.h at the beginning of the file so that
2670 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2673 * regex-posix.c: #include "_scm.h" before conditionally #including
2674 <regex.h>; the former defines HAVE_REGCOMP.
2676 * regex-posix.c: #include <regex.h> conditionally, so the file is
2677 CPP'able (for dependency scanning) even on systems that don't have
2680 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2682 Add new R4RS-compliant syntax for keywords.
2683 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2684 regardless of the setting of the `keywords' read option.
2685 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2686 can be re-read no matter what the setting of the `keywords' read
2689 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2691 Add support for POSIX regular expressions.
2693 * regex-posix.c, regex-posix.h: New files. (Some code
2694 is taken liberally from rx/rgx.c in the old Guile dist.)
2696 * init.c: Include regex-posix.h.
2697 (scm_boot_guile_1): Call scm_init_regex_posix.
2699 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2700 Add regex-posix.[ch] sources.
2701 * Makefile.in: Regenerated.
2703 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2704 to do this automatically? It didn't for me, bleh.)
2706 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2708 * fports.c (print_pipe_port): New function.
2709 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2710 latter doesn't even take the right arguments.
2712 * Makefile.am: Increment shared lib revision number. I think
2713 sometimes the uninstalled Guile finds the installed shared lib;
2714 Gord says doing this might help. As things turned out, I can't
2715 say whether it does.
2716 * Makefile.in: Regenerated.
2718 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2719 passing it as the closure argument to scm_boot_guile. (Bill
2722 * ports.c (print_void_port, putc_void_port, puts_void_port,
2723 write_void_port, flush_void_port, getc_void_port, close_void_port,
2724 noop0): Use ANSI prototypes instead of K&R declarations, so the
2725 initialization of void_port_ptob gets aggressively type-checked.
2726 Fix arguments of print_void_port and write_void_port. (Bill

2760 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2762 * script.c (scm_find_executable): Use prototype-style definition
2763 here; apparently it's not quite right to have const in a prototype
2764 and then use a K&R declaration. I wonder if stuff like this will
2765 go away if we compile with -Wrequire-prototypes, or whatever that
2766 is... (Bernard URBAN)
2768 * scmhob.h: New text from Bernard URBAN.
2770 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2772 * script.c: Don't #define const on hpux. Configure takes care of
2773 this. (Thanks to Larry Schwimmer.)
2775 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2776 decide whether to #include <unistd.h>, instead of listing a bunch
2777 of systems. Don't #include stdio twice. Removed dyked-out
2778 definition of scm_find_impl_file.
2780 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2782 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2783 library version info to 1:0.
2784 * Makefile.in: Regenerated.

2790 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2791 throw.c: Update copyright years; these files have been worked on
2792 significantly in 1997, but only had copyright years for 1996.
2793 Also, change name of copyright holder on some from Mikael
2794 Djurfeldt to Free Software Foundation; he has signed papers
2795 assigning the changes to the FSF.
2797 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2798 reason not to give the user the option.
2800 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2801 Return #f on end-of-file when scanning table (i.e. when called
2802 with no arguments). Try to catch errors, when we can.
2803 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2805 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2806 external declarations. These are useful.
2808 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2810 * posix.c: don't include <sys/select.h> or define macros for
2811 select, since they were not used in this file.
2813 * filesys.c (scm_select): make the fifth parameter microseconds,
2814 not milliseconds. let the fourth parameter be either a real value
2815 or an integer or #f. The first, second and third arguments can
2816 now be vectors: the type of the corresponding return set will be
2818 (set_element, get_element): new static procedures.
2820 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2822 * strports.c (scm_eval_string): New function.
2823 (scm_eval_0str): Trivially re-implemented in terms of
2825 * strports.h (scm_eval_string): New extern decl.
2827 * net_db.c (h_errno): Add extern decl for this.
2829 * fports.c (local_pclose): New function.
2830 (scm_pipob): Use it in the initializer here.
2833 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2834 Use a meaningful error message when signalling an error. For
2835 this, scm_gethost must check h_errno rather than errno.
2837 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2839 * Makefile.in: Regenerated, using automake-1.1p.
2841 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2843 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2844 not SCM_UNSPECIFIED.
2846 * script.c (scm_compile_shell_switches): don't append (quit) if
2848 (scm_shell): call scm_exit_status and exit on the result of the
2851 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2853 Ensure that shared substrings are handled properly when passed to
2854 a system call or other foreign function. Many thanks to Tim
2856 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2857 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2858 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2859 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2871 SCM_COERCE_SUBSTR to make sure shared substrings are
2874 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2876 * error.c (scm_error): Add newline to error message.
2878 * init.c (scm_init_standard_ports): Doc fix.
2880 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2882 * dynl-shl.c: Completely replaced with new code from Bernard
2885 * script.c (scm_ice_9_already_loaded): New variable.
2886 (scm_compile_shell_switches): Use it.
2888 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2890 * filesys.c (scm_input_waiting_p): add missing third argument to
2893 * stime.c (scm_localtime): copy the result of localtime before
2894 calling gmtime in case they share a buffer.
2895 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2898 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2900 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2902 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2904 * Makefile.am (check-local): New target, which causes 'make check'
2905 to run gh_test_c and gh_test_repl, with some trivial input.
2906 * Makefile.in: Rgnrtd.
2908 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2910 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2913 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2915 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2916 sure how this was supposed to work.
2917 (scm_async_click): don't send SCM_TICK_SIGNAL.
2918 (scm_init_async): don't initialize %tick-thunk.
2920 * the following change doesn't affect the Scheme interface:
2921 gc-thunk is called at the end of garbage collection. however it's
2922 no longer implemented by pretending it's a signal.
2924 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2925 system async corresponding to scm_gc_thunk.
2926 * async.h: declare scm_gc_async.
2927 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2928 gc-thunk directly, instead of going through a signal handler.
2929 (scm_gc_async): new variable, points to the GC system-async.
2930 (scm_init_async): save the GC async as scm_gc_async instead
2931 of using system_signal_asyncs.
2932 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2934 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2936 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2937 Don't screw up if we're interrupted.
2938 * Makefile.in: Regeneradet.
2940 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2942 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2944 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2945 we're not using AM_INIT_GUILE_MODULE any more.
2946 * Makefile.in: Reneregated.
2948 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

2951 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2952 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2954 Get 'make dist' to work again.
2955 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2956 * Makefile.in: Regenerated, like a surry without a fringe on top.
2958 Changes for reduced Guile distribution: one configure script,
2960 * configure.in, configure: Removed.
2961 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2962 real configure script lives.
2963 * Makefile.in, scmconfig.h.in: Regenerated.
2965 * init.c: #include "script.h", to get prototype for script.c's
2968 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2970 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2971 scm_must_malloc, not raw malloc.
2973 * script.c (scm_compile_shell_switches): Dyke out debugging output
2976 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2978 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2980 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2981 system has them. Hope this is safe. Previously
2982 sys/timeb.h was included if HAVE_FTIME was defined or if
2983 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2984 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2986 * ioext.c (scm_setfileno): add missing third argument to
2987 scm_misc_error call.
2989 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2991 * eq.c (scm_equal_p): Correctly compare strings of different
2992 varieties. (Thanks to Tim Pierce.)
2994 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2996 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2997 #! block comment must occur on a line all by itself.
2999 Move most of the guts of shell command processing into libguile,
3000 so guile.c can be very small (and eventuallly auto-generated. (I
3001 mean, generated mechanically, not self-generated. Hmm.))
3002 * guile.c, script.c, script.h: New source files.
3003 * init.c (scm_boot_guile_1): Call scm_init_script.
3004 * libguile.h: #include "script.h".
3005 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3006 targets, for new executable.
3007 (libguile_la_SOURCES): Mention script.c.
3008 (modinclude_HEADERS): Add script.h.
3009 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3010 not dynamic linking is enabled. This is because we're generating
3011 executables now. Move CY_AC_WITH_THREADS call after those, so the
3012 values of cy_cv_threads_libs captures the libs chosen above.
3013 * Makefile.in, configure, aclocal.m4: Regenerated.
3015 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3016 We don't maintain this interface any more, and it just confuses
3019 * alloca.c: #include <scmconfig.h>, not <config.h>.
3020 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3021 it'll get included in disties.
3023 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3025 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3026 be distributed, because they confuse people.
3027 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3029 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3031 * configure.in: check for presence of gethostent (not present on
3032 OpenBSD by default).
3033 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3034 * configure, scmconfig.h.in: Regenerated.
3036 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3038 * backtrace.c (scm_backtrace): Split message string across
3039 newlines properly. GCC is more tolerant of this than other

3044 Merge threads directory into libguile.
3045 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3046 threads.h: New source files.

3048 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3050 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3051 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3052 coop-threads.c.cygnus, coop-threads.h.cygnus.
3053 * configure.in: If we're using threads, include threads.o in
3055 * _scm.h, libguile.h: threads.h lives in this directory now.
3056 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3057 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3058 currently used, but brought along for information's sake.
3059 * ChangeLog-threads: log from old 'threads' directory.
3060 * Makefile.in, configure: Rebuilt.
3062 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3064 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3067 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3069 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3071 Merge GH interface library into libguile.
3072 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3073 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3074 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3075 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3077 (EXTRA_libguile_la_SOURCES): ... here.
3078 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3079 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3080 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3081 New variables, describing how to build the gh test programs.
3082 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3083 build the test programs, and we probably should have been linking
3084 libguile.la against them all along, to support AIX shared libs.
3085 Add cflags for threads to CFLAGS; add libs for threads to new
3086 variable THREAD_LIBS, used in Makefile.am.
3087 * ChangeLog-gh: log from old `gh' subdirectory.
3088 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3090 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3092 * acconfig.h: Undo change of Apr 9; including the definition of
3093 PACKAGE in the guile headers conflicts with applications' own
3095 * scmconfig.h.in: Regenerated.

3106 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3108 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3109 have S_IFSOCK. This is the case under Ultrix.
3111 * posix.c (scm_status_exit_val, scm_status_exit_val,
3112 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3113 Ultrix versions of WIFSTOPPED, etc., which assume that their
3114 arguments are lvalues (hmm).
3116 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3118 * eval.c: Doc fixes.
3120 * throw.c: Doc fixes; rearranged.
3122 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

3126 * acconfig.h: Added entry for PACKAGE.
3127 * scmconfig.h.in: Regenerated.

3130 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3131 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3133 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3135 * Makefile.in: Rebuild.
3137 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3139 * stime.c (scm_mktime): take an optional zone argument.
3140 (scm_localtime): check putenv return value.
3141 (scm_strftime, scm_strptime): moved from posix.c. move #include
3143 stime.h, posix.h: update prototypes.
3144 (bdtime2c, setzone, restorezone): new static procedures.
3145 (scm_mktime, scm_strftime): use them.
3146 (scm_strftime): don't call mktime before strftime. Use
3147 filltime for return value.
3148 (filltime): convert NULL zname to #f.
3149 (scm_strptime): return a count of characters consumed, not
3150 the remaining string.
3152 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3154 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3155 (scm_mktime): likewise.
3157 Uncomment localtime and mktime.
3159 * configure.in: add AC_STRUCT_TIMEZONE.
3161 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3163 * stime.c (scm_init_stime): don't define ticks/sec.
3164 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3165 return value problem and is still portable.)
3167 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3169 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3170 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3171 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3172 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3173 cpp_err_symbols.c): Corresponding changes.
3174 * Makefile.in: Regenerated.
3176 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3178 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3179 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3180 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3181 * putenv.c: new file, from sh-utils 1.12.
3183 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3184 since allocation isn't for Scheme objects.
3185 (scm_putenv): copy strings before placing in the environment.
3187 * stime.c (scm_current_time): throw an error if time returns -1,
3188 instead of returning #f.
3189 (scm_get_internal_real_time, scm_get_internal_real_time): use
3190 scm_long2num for return value instead of SCM_MAKINUM.
3192 * stime.h: prototypes updated.
3194 * stime.c (scm_time_in_msec): apparently unused, deleted.
3196 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3198 * configure.in: check for gettimeofday.
3200 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3201 which may be more usefully portable than a gettimeofday interface.
3203 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3205 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

3209 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3211 * stime.c (filltime): recovered static procedure.
3212 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

3216 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3218 * posix.c (scm_mknod): split the mode argument into type and perms
3219 arguments, like the extra fields returned by stat.
3221 * fports.c (scm_pipob): set the close, free and print procedures.
3222 (scm_close_pipe): new procedure.
3224 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3225 define them in boot-9.scm
3227 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3229 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3230 wan't defined. Don't include fd.h.
3232 * Previously fd.h was regenerated whenever configure was run,
3233 forcing a couple of files to be recompiled.
3235 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3236 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3237 Check for _fileno as well as _file.
3239 * ioext.c: don't fd.h.
3240 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3243 * Change the stratigy for getting information about errno
3244 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3245 generating lists of symbols during the build process, which will
3246 not always work, include comprehensive lists in the distribution.
3247 To help keep the lists up to date, the "check_signals" and
3248 "check_errnos" make targets can be used.
3250 * configure.in: don't check for a command to extract errno codes.
3251 * Makefile.am: update file lists, remove errnos.list and errnos.c
3252 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3253 check_errnos targets.
3254 (CLEANFILES): remove errnos.c and errnos.list, add
3255 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3256 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3257 * errnos.default: deleted.
3258 * cpp_signal.c: new file.
3259 * cpp_errno.c: renamed from errnos_get.c.
3260 * cpp_err_symbols, cpp_sig_symbols: new files.
3261 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3262 * error.c (scm_init_error): #include cpp_err_symbols instead of
3264 * posix.c (scm_init_posix): don't intern signal symbols. #include
3267 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3269 * strop.c (scm_i_index): allow the lower bound to be equal to the
3270 length of the string, so a null string doesn't always give an error.
3272 * posix.h: new prototypes.
3273 * posix.c (scm_status_exit_val, scm_status_term_sig,
3274 scm_status_stop_sig): new functions, as in scsh. They break down
3275 process status values as returned by waitpid.
3277 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3279 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3280 configure doesn't know about it.
3282 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3284 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3286 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3287 which defines C variables with global linkage.
3289 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3291 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3294 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3296 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3297 has time to check why this doesn't work well with continuations.
3299 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3301 * Fix shell syntax error; some shells won't tolerate
3302 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3304 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3306 * posix.c (scm_uname): throw an error if uname fails instead
3309 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

3318 * acconfig.h: Removed PACKAGE.
3320 * scmconfig.h.in: Regenerated.
3322 * snarf.h: g++ says it's non-portable not to specify the first
3323 argument in a varargs declaration. I introduced the first
3324 argument by using preprocessor conditionals.
3326 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3328 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3329 (scm_freopen): use RO string macros for filename and modes.

3336 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3338 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3339 use SCM_ROSTRINGP and SCM_ROCHARS.

3343 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3346 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3348 support for byte vectors.
3350 * print.c (scm_iprin1): Limit number of vector elements printed
3351 according to pstate->length.
3353 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3358 * error.h: prototype for scm_error_scm.
3360 * error.c (scm_error_scm): new procedure, reimplements scm-error
3361 in C and uses scm_error.
3363 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3365 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3366 pointer to the Scheme variable read-hash-procedures and intern it
3367 in scm_init_read. Modify scm_read_hash_extend and
3368 scm_get_hash_procedure to use the pointer.
3370 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3372 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3373 (SCM_KEYWORD_STYLE): defined.
3375 * read.c (scm_read_opts): add a keywords option. This isn't a
3376 boolean option, in case someone wants to add support for DSSSL
3378 Setup scm_keyword_prefix symbol.
3379 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3381 I've left keyword support disabled by default, since it doesn't
3382 seem to break the module system and it gives R4RS standard behaviour.
3383 It can be reactivated with (read-set! keywords 'prefix).
3385 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3387 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3388 before constructing arbiter.
3390 * eval.c (scm_m_define): Bugfix: Check that the object is a
3391 closure before setting the procedure property!
3393 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3395 * ports.c: Removed `ungetc-char-ready?'.
3397 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3399 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3400 (idea from Mikael: make it a pair so scm_permanent object only
3402 (scm_read_hash_extend): don't call scm_permanent_object.
3403 (ideas from Mikael): if chr is already in the list, replace its
3404 procedure instead of appending it again. If proc is #f, remove
3406 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3408 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3410 * gdbint.c (gdb_read): update scm_lreadr usage.
3412 * load.h: update prototypes.
3414 * load.c (scm_primitive_load, scm_read_and_eval_x,
3415 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3417 * read.h: add prototype for scm_read_hash_extend. Change args for
3420 * read.c (scm_read_hash_procedures): new variable.
3421 (scm_read_hash_extend): new procedure.
3422 (scm_get_hash_procedure): new procedure.
3423 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3424 for extended # processing.
3425 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3426 scm_read_token): remove case_i, sharp arguments. Change callers.
3428 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3430 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3431 (SCM_CASE_INSENSITIVE_P): define.
3433 * read.c: add case-insensitive option to scm_read_opts.
3434 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3435 to determine whether to convert symbol case.
3436 (default_case_i): definition removed.
3437 * read.c (scm_read_token): if case_i, downcase ic before doing
3440 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3442 * configure.in: Added configuration option `guile-debug'.
3443 Configure with --enable-guile-debug if you want a bunch of extra
3444 functions used for debugging when developing Guile.
3446 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3448 * procs.c (make-cclo): New undocumented debugging procedure: Make
3449 compiled closure with internal procedure PROC and length LENGTH.
3450 Only compiled if GUILE_DEBUG is defined.
3452 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3454 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3456 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3458 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3459 with 3 or more args internally to the evaluator.
3461 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3463 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3464 with 3 or more args internally to the evaluator. This is mainly
3465 because we don't want to pass entry and exit points of the
3466 debug support twice, but it also seems to increase the speed of
3467 the evaluator for such calls (e. g. (+ 1 2 3)).
3469 * backtrace.c (scm_display_application): New procedure:
3470 display-application; Set fancy printing parameters individually
3471 for different types of display (backtrace, error, application).
3472 (These should of course be customizable!)
3474 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3475 clear the CHECK-flags.
3477 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3479 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3481 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3483 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3484 from pairs with a GLOC in the car.
3486 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3487 otherwise `symbol-hash' will behave badly.
3488 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3489 we get segmentation fault!
3491 * symbols.c: Added #include "weaks.h". New functions:
3492 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3493 moved to an extraneous library when we split libguile.)
3495 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3497 * filesys.c (scm_stat): stat now takes fport arguments too as
3498 documented in the manual.
3500 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3502 * debug.c (scm_single_step): Bugfix: Call continuation with
3503 scm_call_continuation instead of throwing to it.
3505 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3507 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3508 argument wasn't declared to be optional.
3510 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3512 * stime.c (scm_init_stime): Add feature "current-time".
3514 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3516 * throw.h: prototype for scm_exit_status.
3517 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3518 args to derive an exit status. Allows (quit) to work from a
3520 (scm_exit_status): new function.
3523 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3525 * eval.c (scm_deval): Removed some old code.
3526 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3528 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3531 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3534 * procs.c: Introduce the existent C function scm_thunk_p at the
3535 Scheme level as well.
3537 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3539 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3540 used from C to easily lookup the value of a symbol in the current
3543 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3545 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3546 scm_init_unif in this file. This will also fix a previous problem
3549 * configure.in: Added AM_MAINTAINER_MODE
3551 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3553 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3556 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3558 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3559 source files that are not always included in libguile but should
3560 have their dependencies calculated by automake. This variable is
3561 recognized by automake, no further magic is needed.
3562 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3563 to deal exclusively with *.lo files, as it seems. The *.o files
3564 are built automatically when the corresponding *.lo file gets
3567 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3569 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3572 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3574 * unif.c (scm_array_set_x): minor change to argument error checking.
3576 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3578 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3579 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3580 They should only be included in the library at configure.in's
3582 (libguile_la_LDADD): Include the appropriate .lo files here.
3583 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3584 so we know when to build them (and their .lo bretheren).
3585 * configure.in (LIBLOBJS): New substituted variable. We let
3586 configure decide which .o files to include in LIBOBJS, and then
3587 put the corresponding list of .lo files in LIBLOBJS. The latter
3588 is what we pass to libtool.
3589 * Makefile.in, configure: regenerated.
3591 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3593 * symbols.c (scm_sysintern0): New function. Contains the core of
3594 old scm_sysintern but doesn't take a second value argument.
3595 (scm_sysintern): Now uses scm_sysintern0.
3596 (scm_sysintern_no_module_lookup): Renamed to
3597 scm_sysintern0_no_module_lookup and doesn't take a second value
3598 argument any longer.
3600 * symbols.h (scm_sysintern0: Added declaration.
3602 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3603 scm_sysintern when interning option keys. Otherwise we risk
3604 destroying the values of already interned variables.
3606 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3607 scheme-level boolean (use SCM_NFALSEP).
3609 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3611 (scm_backtrace): New function. (C version of old function from
3612 boot-9.scm) Motivation: Make it possible to display backtraces
3613 without depending on boot-9.scm. (I'm uncertain if this
3614 motivation is good enough...)
3616 * root.h (scm_root_state): Add member the_last_stack_var.
3617 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3619 * root.c (mark_root): Mark scm_the_last_stack_var.
3621 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3624 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3626 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3627 1. mark_lazy_catch didn't mark the smob.
3628 2. Both functions above have standard variants:
3629 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3630 free_lazy_catch --> scm_free0.
3632 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3634 * throw.c (scm_internal_lazy_catch): New function.
3635 (scm_lazy_catch): Rewritten to use it.
3636 (scm_ithrow): Handle the new lazy catch representation.
3637 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3638 that doesn't have a jmpbuf is a lazy catch clause.
3639 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3640 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3641 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3643 (scm_init_throw): Register the new lazy-catch smob type.
3644 * throw.h (scm_internal_lazy_catch): decl for new function.
3646 * throw.c (scm_internal_catch): Doc fixes.
3648 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3649 configure.in. Including this might cause problems if applications
3650 that link against libguile include their own copies of alloca, but
3651 if they're using autoconf, they should be adding libguile to LIBS
3652 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3653 the copy in libguile, and things will be okay. (I think.)
3655 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3657 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3659 strop.h: move prototypes too.
3661 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3663 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3666 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3667 etc. I deleted them from filesys.c long ago, but didn't
3668 notice they were here too (although ineffective since
3669 sys/stat.h wasn't included).
3671 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3673 * eval.c: Don't define alloca in GCC case. gcc will automatically
3674 use __builtin_alloca if appropriate.
3676 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3678 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3679 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3680 that values of automatic variables are preserved. See comments
3681 for safe_setjmp for details.
3683 Change from Thomas Morgan:
3684 * variable.c: Include eq.h.
3685 (var_equal): New function.
3686 (variable_smob): Use var_equal as the discriminator for variables.
3688 * throw.c (s_throw): Remove extraneous declaration.
3690 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3691 * eval.c: Add necessary CPP cruft to support that.
3692 * configure, Makefile.in, scmconfig.h.in: regenerated.
3694 Change from Thomas Morgan:
3695 * procprop.c (scm_procedure_properties): Convert the Scheme
3696 boolean returned by scm_procedure_p into a C boolean before using
3697 it as a condition for SCM_ASSERT.
3698 (scm_procedure_property): Likewise.
3700 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3701 indications of Unixness.
3704 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3706 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3708 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3710 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3711 "unknown # object" error messages.
3713 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3714 (scm_i_index) and declare it static. Add a 'direction' argument
3715 to indicate what way the search should go.
3716 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3718 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3719 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3721 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3723 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3725 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3726 to avoid clash with various scsh forks.
3728 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3730 The following two changes (ramap.c, throw.c) are motivated by the
3731 apparent unportability of forward declarations of static arrays of
3732 the form `static foo bar[];'.
3734 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3735 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3737 * throw.c (scm_throw): Moved above scm_ithrow.
3739 * options.h: Removed the extern declarations of scm_yes_sym and
3740 scm_no_sym since these are static.
3742 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3744 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3746 * Makefile.am: remove AWK=@AWK@.
3747 Add a rule for generating errnos.list.
3748 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3750 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3751 don't extract errnos, just set a variable (avoids the
3752 need to recompile error.c just because configure is run.)
3754 * unif.h: update prototypes.
3755 * unif.c (scm_uniform_array_read,write): change the offset and
3756 length arguments to start and end, for consistency.
3758 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3760 * ioext.h: update prototypes.
3761 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3762 scm_read_line_x, it's a more general procedure using an
3763 interface from scsh. read-line and read-line! are now defined
3765 Note that the new read-line trims the terminator
3766 by default, previously it was appended to the returned string. An
3767 optional argument specifies how to process the terminator (scsh
3768 compatible). For the old behaviour: (read-line port 'concat).
3769 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3770 returns a pair, but is converted to multiple values if the scsh
3773 socket.h: update prototypes.
3774 * socket.c (scm_recvfrom): for consistency with other procedures,
3775 take start and end as separate optional arguments.
3776 (scm_recv, scm_recvfrom): don't allow the second argument
3777 to be a size, only a buffer. Change the scheme names to
3778 recv! and recvfrom!. Don't return the buffer.
3780 * ioext.h, posix.h: move prototypes too.
3781 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3782 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3783 "read.h" and "unif.h".
3784 * ioext.c: include "chars.h"
3786 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3788 * dynl.c: The dynamic linking and module registration functions
3789 are now defined even when dynamic linking is not available for the
3790 host system. Some of their functionality can be done without
3791 dynamic linking; when it's really needed, they throw errors.
3793 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3795 * configure.in: Only define DYNAMIC_LINKING when one of the system
3796 dependent functions is detected.
3797 * dynl.c (scm_dynamic_func): New function to get the address of a
3798 function in a dynamic object.
3799 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3800 produced by scm_dynamic_func as the thing to call.
3802 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3804 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3805 (scm_register_module_xxx, scm_registered_modules,
3806 scm_clear_registered_modules): New functions.
3808 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3810 * symbols.c (scm_sysintern): Renamed to
3811 scm_sysintern_no_module_lookup.
3812 (scm_sysintern): New function to take the place of the old
3813 scm_sysintern. It uses the current toplevel lookup closure to give
3814 the symbol its value. This is a temporary hack to put packages
3815 like gtcltk into their own module.
3816 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3817 us whether `scm_top_level_lookup_closure_var' has been initialized
3819 * eval.c (scm_init_eval): Set it.
3821 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3823 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3824 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3826 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3828 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3829 scm_sys_dup): deleted: FD capability will be added to other
3831 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3832 scm_fd_free, fd_smob, scm_intern_fd.
3833 (scm_open): renamed from scm_sys_open. Return a port instead of
3834 an FD object. Make the mode argument optional.
3835 (scm_sys_create): deleted, it's just a special case of open.
3836 (scm_init_filesys): move interning of constants O_CREAT etc.,
3837 here (were previously using SCM_CONST_LONG macro).
3838 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3840 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3841 include "fports.h" and <stdio.h>
3842 (scm_stat, scm_select): don't support FD objects.
3844 * error.h: adjust scm_syserror_msg prototype.
3845 * error.c (scm_syserror_msg): take an extra argument for errno.
3846 Using the global value didn't always work, since it could be
3847 reset by procedure calls in the message or args arguments.
3849 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3850 I don't understand why the check was there (and what about the
3853 * strop.c (scm_string_copy): allow shared substrings to be copied.
3855 * unif.h: corresponding change to prototypes.
3856 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3857 recognize two new optional arguments: offset and length. Allow
3858 the port argument to be an integer (file descriptor, for scsh).
3859 Include <unistd.h> for "read" prototype.
3861 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3863 * socket.c: don't include filesys.h.
3865 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3867 * Makefile.am: add AWK=@AWK@ (?)
3869 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3871 Add a rule to generate errnos.c from errnos.
3872 * error.c (scm_init_error): include errnos.c.
3873 * errnos_cnvt.awk: new file, converts the list of errno codes to
3875 * errnos_get.c: new file.
3876 * errnos.default: new file, contains errnos to try if they can't
3877 be extracted from errno.h.
3878 * configure.in: if using GCC, try and extract errno codes from
3882 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3884 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3885 * Makefile.am: Made libguile into a libtool library.
3886 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3887 Set libtool_libs to indicate that libguile is a libtool library.
3888 See guile/ChangeLog for details.
3889 * .cvsignore: ignore "*.lo", the libtool library objects.
3891 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3893 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3894 use htons in getservbyport argument.
3896 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3898 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3899 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3902 * objprop.c (scm_object_property): No need to take the CDR of the
3903 value returned by scm_object_properties, since Aug 20 change.
3905 * configure.in: When checking for struct linger, #include
3906 <sys/types.h> as well as <sys/socket.h>. I've never known
3907 <sys/types.h> to cause any portability problems, and Solaris's
3908 <sys/socket.h> needs it.
3909 * configure: Rebuilt.
3911 I think the Sun compiler has chosen a perverse way to interpret
3912 ANSI declarations combined with K&R definitions. We'll
3913 appease it a little bit. But when it invades France, we fight.
3914 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3915 * print.h (scm_iprlist): Here too.
3916 * numbers.c (scm_divbigdig): Change definition to match
3917 declaration in numbers.h.
3918 * unif.c (scm_makflo): Change definition to match declaration in
3921 * init.c (scm_boot_guile): Don't return the value of
3922 scm_boot_guile_1. This function doesn't return a value;
3923 scm_boot_guile_1 doesn't return a value (or return at all).
3925 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3928 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3929 compile. I have a feeling this function is a bad idea anyway ---
3930 one should always test for features, not systems.
3932 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3933 semicolons. Only pure luck kept this from being noticed earlier.
3935 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3937 * socket.c (scm_recvfrom): Added missing semicolon.
3939 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3941 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3942 the buffer and start and end positions for scsh networking
3945 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3947 * configure.in: Revert previous change to this file; the problem
3948 is due to transient automake weirdness.
3949 * configure: Rebuilt.
3951 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3952 PLUGIN/guile.libs. configure generates the latter from the former.
3953 * Makefile.in: Rebuilt.
3955 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3956 need this if we install scripts, like guile-snarf.
3957 * configure: Rebuilt.
3959 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3961 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3963 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3965 * socket.c (scm_addr_vector): fix faulty scm_listify.
3967 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3969 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3970 style block comment is no longer considered an error.
3972 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3974 * PLUGIN/guile.libs.in: New file.
3975 * PLUGIN/guile.libs: Removed from repository.
3976 * configure.in: Create PLUGIN/guile.libs from
3977 PLUGIN/guile.libs.in. This is for including additonal libraries
3978 needed for dynamic linking.
3979 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3980 instead of PLUGIN/guile.libs.
3982 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3984 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3986 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3987 occurrences of the given element from the list, not just the
3988 first. This is how the Emacs Lisp functions behave, how the
3989 analogous Common Lisp functions behave, and (I believe) how the
3990 older Maclisp functions worked. I realize that this change may
3991 break code, but it seemed better to break it before the Guile
3994 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3995 Their prototypes were already present in gc.h, but they weren't
3997 (scm_init_storage): Initialize scm_protects.
3998 * root.c (scm_protects): New element of scm_sys_protects.
4000 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4002 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4004 * libguile.h: Added #include "libguile/net_db.h".
4006 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4007 30 change. That file is only meant for communication between the
4008 configuration process and load.c. If code linked against libguile
4009 wants to get at the paths mentioned in libpath.h, it can call
4010 functions declared in load.h.
4012 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4014 * libguile.h: Removed #include "libguile/fdsocket.h"
4016 * net_db.c: Added #include <sys/socket.h>.
4018 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4020 * filesys.c (scm_input_waiting_p): use select in preference to
4021 FIONREAD, since the latter doesn't detect EOF.
4022 Throw error if neither select nor FIONREAD available.
4024 * socket.c (scm_connect): take a port, not a fd object.
4025 (scm_fill_sockaddr): throw an error if fam is not recognised.
4026 (scm_bind): use scm_fill_sockaddr.
4027 (scm_listen): take a port, not a fd object.
4028 (scm_accept): take and return a port. return #f in the car if
4029 address can't be got
4030 (scm_sock_fd_to_port): new procedure.
4031 (scm_socket): use scm_sock_fd_to_port.
4032 (scm_addr_vector): throw error if unrecognised address type.
4033 take an extra argument with the calling procedure name.
4034 (scm_getsockname): take a port. return #f if address can't be got.
4035 (scm_getpeername): take a port. return #f if address can't be got.
4036 (scm_recvfrom): take a port. return #f for address component if can't
4038 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4039 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4041 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4043 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4044 use separate data pointers, to allow them to be designed
4045 independently and reused.
4046 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4047 Renamed from catch_body, catch_handler, and uncaught_throw; made
4049 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4051 (scm_catch): Use the above.
4052 (scm_throw): Don't bother printing a message for an uncaught
4053 throw; we establish a default handler in init.
4054 * throw.h (scm_internal_catch): Prototype updated.
4055 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4057 (struct scm_body_thunk_data): New structure, used as data
4058 argument to scm_body_thunk.
4059 * init.c (struct main_func_closure): New structure, packaging up
4060 the data to pass to the user's main function.
4061 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4062 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4063 scm_internal_catch to establish a catch-all handler, using
4064 scm_handle_by_message. This replaces the special-case code in
4066 (invoke_main_func): Body function for scm_internal_catch; invoke
4067 the user's main function, using the main_func_closure pointer to
4068 decide what to pass it.
4069 * root.c (struct cwdr_body_data): Remove handler_proc member.
4070 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4071 (cwdr_handler): Removed.
4073 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4075 * socket.h (SCM_P): update bind prototype.
4076 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4077 include "feature.h".
4078 (scm_socket): return a port, not a file descriptor object.
4079 include "fports.h" and <unistd.h>
4080 (scm_bind): take a port, not a file descriptor object.
4081 take an extra argument for address args.
4083 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4084 INADDR_NONE, INADDR_LOOPBACK.
4086 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4088 * init.c: include net_db.h and not fdsocket.h.
4089 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4091 * Makefile.am: corresponding changes.
4092 * socket.h: renamed from fdsocket.h, fix names.
4093 * net_db.h: renamed from socket.h, fix names.
4094 * socket.c: renamed from fdsocket.c.
4095 remove _sys from procedure names.
4096 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4097 add "socket" to features list.
4098 * net_db.c: renamed from socket.c.
4099 remove _sys from procedure names.
4100 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4101 add "net-db" to features list.
4102 include "net_db.h". don't include <sys/socket.h> or
4105 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4107 * tags.h (scm_tags): Removed comma at end of last enumerator.
4109 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4111 Don't use GCC extensions to allocate space for debugging frames.
4112 (Here he goes again! Why do we put up with this?!)
4113 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4114 an scm_debug_info structure, not an in-line array of them. Add
4115 'info' member, to say how many vect elements we've used, for eval
4117 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4118 a new variable debug_info_end to mark the end of vect, instead of
4119 the address of the 'info' pointer itself.
4120 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4121 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4122 (SCM_APPLY): Explicitly allocate space for debug.vect.
4123 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4124 * stacks.c: Adjusted for new debug frame structure.
4125 (RELOC_INFO, RELOC_FRAME): New macros.
4126 (stack_depth, read_frames): Use them, and new scm_debug_frame
4127 element 'info', instead of magically knowing that eval frames have
4128 an info pointer sitting after vect.
4129 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4131 (scm_init_stacks): Formatting tweaks.
4133 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4135 Give GCC more control flow information, so it can be sure that
4136 variables aren't used uninitialized.
4137 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4138 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4139 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4140 scm_misc_error): Tell GCC that these functions never return.
4141 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4142 out the field type, call abort if SCM_ASSERT returns, to placate
4144 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4145 scm_wta ever returns. We can't handle this case anyway, and this
4146 gives the optimizer more information.
4147 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4148 scm_wta ever returns.
4150 In some cases, the code is fine, but GCC isn't smart enough to
4151 figure that out; this usually happens when one variable is only
4152 initialized and used when a particular condition holds true, and
4153 we know that condition will never change within a given invocation
4154 of the function. In this case, we simply initialize the variables
4155 to placate the compiler, hopefully to a value which will cause a
4156 crash if it is ever actually used.
4157 * print.c (scm_iprin1): Initialize mw_pos.
4158 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4159 * throw.c (scm_ithrow): Initialize dynpair.
4160 * unif.c (scm_uniform_vector_ref): Initialize cra.
4161 * struct.c (init_struct): Initialize prot.
4162 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4164 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4165 if EXPR contains no expressions.
4167 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4169 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4170 cause an infinite loop (???). So much for the algebraic
4171 equivalency of variable-sized arrays and alloca...
4173 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4175 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4176 a SCM boolean, not a C boolean.
4178 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4180 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4181 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4182 rules for raising scm_mtrigger. Previously, unfortunate but not
4183 unlikely circumstances could result in almost constant invokation
4184 of the gc. Now, this situations should be less likely, but they
4185 are not prevented completely.
4187 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4189 * numbers.c (scm_fuck): Procedure removed; looks like old test
4191 * numbers.h: Prototype removed.
4193 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4195 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4196 array to a pointer, to match my Nov 21 change in eval.c.
4198 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4200 * libguile.h: Added #include "libguile/backtrace.h", #include
4201 "libguile/stacks.h".
4203 * strings.c (scm_string scm_make_string scm_string_ref
4204 scm_string_set_x scm_string_equal_p scm_string_append):
4205 Bugfix according to scm patch from Aubrey Jaffer:
4206 Corrected long-standing
4207 (not (eqv? (integer->char 128)
4208 (string-ref (make-string 1 (integer->char 128)) 0)))
4209 bug found by John Kozak <jk@noontide.demon.co.uk>.
4211 * strports.c, strports.h: Make scm_eval_0str return the value of
4212 the last expression evaluated (previously, it returned void).
4214 * strports.c, strports.h: New function: scm_read_0str. Does what
4217 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4219 * simpos.c (scm_getenv): return #f if string can't be found in the
4220 environment instead of throwing an exception, for compatibility
4221 with numerous other systems.
4223 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4225 * Makefile.am (.c.x): Use guile-snarf.
4226 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4228 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4230 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4232 * backtrace.c (scm_display_error_message): Made non-static, and
4233 renamed from display_error_message.
4234 * backtrace.h (scm_display_error_message): Added extern decl.
4235 * throw.c (uncaught_throw): Use it to display the error message.
4237 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4239 * inet_aton.c: Use #if 0, not #ifdef 0.
4241 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4243 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4244 to convert the returned value.
4245 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4246 the offset argument.
4248 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4250 Add new interface to catch/throw, usable from C as well as
4252 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4253 (scm_internal_catch): New function, replaces...
4254 (scm_catch_apply): Deleted.
4255 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4256 mechanism which is a bit more code, but can be used nicely from C
4257 and implement the Scheme semantics as well.
4258 (scm_internal_catch): This is the replacement; it's named after
4259 the analogous function in Emacs.
4260 (scm_catch): Reimplemented in terms of the above.
4261 (struct catch_body_data, catch_body, catch_handler): New
4262 functions, used by scm_catch.
4263 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4264 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4265 support for new cwdr.
4267 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4270 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4272 * acconfig.h: Added DYNAMIC_LINKING symbol.
4273 * configure.in: Add option and checks for dynamic linking.
4274 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4275 dynl.h: New files for dynamic linking support.
4276 * Makefile.am (libguile_a_SOURCES):
4278 (modinclude_HEADERS): Added "dynl.h".
4279 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4281 * init.c (scm_boot_guile_1): Call
4282 scm_init_dynamic_linking to initialize dynamic linking support.
4284 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4286 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4287 (as we Schemers say). It needs to be global, so that I can tweak
4288 it for the proper operation of unexec.
4289 (scm_boot_guile_1_live): New variable, see above.
4291 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4293 * guile-snarf.sh: Removed.
4294 * PLUGIN/guile.libs: Added dependency for -lm.
4295 * acinclude.m4: Renamed from aclocal.m4.
4296 * PLUGIN/greet: Removed.
4297 * Makefile.am, aclocal.m4: New files.
4298 * configure.in: Updated for Automake.
4300 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4302 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4303 and not top_level_lookup_thunk_var.
4305 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4307 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4309 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4311 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4312 Scheme function, instead of syntax. Single argument is now a
4315 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4317 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4318 scm_ra_divide): Properly terminate statements passed as arguments
4319 to IVDEP macros. (Thanks to Bernard Urban.)
4321 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4322 with non-constant sizes. (Thanks to Bernard Urban.)
4324 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4326 It's an "eval closure", not an "eval thunk." A thunk is a
4327 function of no arguments.
4328 * root.h (struct scm_root_state): Renamed
4329 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4330 (scm_top_level_lookup_closure_var): Renamed from
4331 scm_top_level_lookup_thunk_var.
4332 * root.c (mark_root): Uses changed.
4333 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4334 * init.c (scm_start_stack): Uses changed.
4335 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4336 Change scheme-visible name to *top-level-lookup-closure* from
4337 *top-level-lookup-thunk*.
4339 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4341 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4342 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4344 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4346 * gc.c (struct scm_heap_seg_data): Doc fixes.
4348 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4349 sweeping. Then, prepend each segment's free cells to its
4350 freelist, rather than wiping out the old value. (Thanks to Marius
4353 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4354 scm_check_freelist, scm_debug_newcell): New functions and
4355 variables, for debugging freelist problems.
4356 * pairs.h (SCM_NEWCELL): New debugging version added.
4357 * gc.h (scm_debug_newcell): Added extern declaration, used by
4358 debugging version of SCM_NEWCELL.
4360 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4362 On some systems <libc.h> conflicts with <unistd.h>, and should not
4363 be #included at all.
4364 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4365 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4366 * configure.in: Call it.
4367 * posix.c, filesys.c: Use its results to decide whether or not to
4369 * configure, scmconfig.h.in: Rebuilt with autoconf and
4372 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4374 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4375 pointer to the stdio stream before calling scm_setbuf0, so the
4376 latter will be able to retrieve it. I'm surprised this didn't
4377 segfault earlier. (Thanks to Christopher Lee.)
4379 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4381 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4384 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4386 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4387 number of stack narrowing specifier pairs. The first specifier in
4388 a pair controls inner border, the second the outer border. A
4389 number means cut that number of frames, a procedure object means
4390 cut until that object is found in operator position in a frame.
4392 * root.c (cwdr): Bugfix.
4394 * read.c: Recording of positions disabled by default.
4396 * procs.c (scm_closure_p): New function.
4398 * posix.c (scm_tmpnam): New function.
4400 * load.c: Added #include "throw.h".
4401 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4404 * load.c, load.h (scm_read_and_eval_x): New function.
4406 * eval.c: Renamed debug option "deval" to "debug".
4408 (scm_eval_x): `eval!' is no longer accessible from the scheme
4409 level. Motivation: We can't allow operations which introduce
4410 glocs into the scheme level. Guile's type system can't handle
4411 these as data. Use `eval' or `read-and-eval!' as replacement.
4413 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4414 SCM_CONSP since this is a macro!; Set vframe.prev to
4415 scm_last_debug_frame instead of 0. In this way we can look
4416 "above" the virtual start stack frame if we wish.
4417 (scm_debug_hang): New function: Useful for debugging Guile in
4418 certain tricky situations. Will probably be removed later...
4420 * debug.h: Changed semantics of debug option "backtrace". This
4421 option now only indicates whether we want automatic backtrace at
4424 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4426 * ports.c: #include "filesys.h"
4427 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4429 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4430 Motivation: This is system specific code which is related to file
4431 I/O. It also may use select. Added code by Gary Houston to
4432 detect presence of character in stdio buffers.
4434 * libguile.h: #include "libguile/libpath.h"
4436 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4437 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4438 SCM_SITE_DIR; Install libpath.h among the other include files.
4440 * load.c, load.h (scm_sys_package_data_dir): New function.
4442 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4444 * stacks.h: Bugfix: Don't use tail-array length field as stack
4445 length field! This screwed GC.
4447 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4449 * _scm.h: Added #ifndef around definition of macros min and max.
4451 * __scm.h: Added hooks for threads to plugin to in ints protection
4452 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4453 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4454 the main code in these macros duplicated and spread over multiple
4455 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4456 SCM_THREAD_SWITCHING_CODE.
4458 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4460 * snarf.h: New file.
4461 * guile-snarf.sh: New file.
4462 * Makefile.in (inner_h_files): Added snarf.h
4463 (ancillary, install, uninstall, distclean): Added actions for
4465 (.c.x): Use guile-snarf.
4466 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4467 (gen_c_files): Note that these depend on guile-snarf.
4468 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4469 now in "snarf.h". Added #include "snarf.h" to get them.
4470 * libguile.h: Added #include "snarf.h".
4471 (Patches applied and tweaked by Jim Blandy.)
4473 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4475 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4476 standards suggest against providing prototypes for system
4477 functions. Thanks to Greg Troxel.
4479 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4481 * strports.c (scm_eval_0str): New function.
4482 #include "read.h", to get prototype for scm_read.
4483 * Makefile.in (strports.o): Update dependencies.
4484 * strports.h: New prototype.
4486 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4487 scheme name from "int?" to "integer?". It seems to do the job.
4488 * numbers.h: Rename prototype too.
4489 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4492 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4493 scm_num_eq_p): Rename these according to R4RS conventions: call
4494 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4495 to making libguile R4RS compliant without ice-9...
4497 * load.c (scm_sys_search_load_path): Search for files under all
4498 extensions listed in the %load-extensions variable. If FILENAME
4499 is absolute, return it unchanged, without searching the load path.
4500 (scm_loc_load_extensions): New variable, pointing to
4501 %load-extensions' value cell.
4502 (scm_init_load): Initialize it, and the value it points to.
4503 (scm_primitive_load_path): Improve error reporting.
4505 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4506 of new Scheme variable %load-hook.
4507 (scm_primitive_load): Apply %load-hook to filename.
4509 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4511 * configure.in: add tests for figuring out whether buffered data
4512 is available in a FILE structure, which is needed by char-ready.
4514 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4517 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4518 exceptions using misc_error instead of syserror. It seems a bit
4519 odd to throw an exception if a string can't be found in the
4520 environment, but it's consistent with open-file, stat etc.
4521 (simpos.h): remove sys_ from getenv.
4523 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4524 occurs, throw an error instead of returning errno. Return value
4526 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4528 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4530 * filesys.c (scm_stat2scm): derive file type and permissions from
4531 the stat mode and append them to the returned vector.
4532 There isn't much overhead in doing this and it avoids the need to
4533 work with S_IRUSR et al. in Scheme.
4534 Define symbols scm_sym_regular etc.
4535 (scm_init_filesys): don't intern S_IRUSR etc.
4537 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4538 and s_primitive_load_path.
4540 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4542 * error.h: don't declare error symbols. prototype for scm_misc_error.
4544 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4547 * error.c: use SCM_SYMBOL to set up error keys.
4548 scm_misc_error: new procedure.
4550 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4552 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4553 between `#!' and `!#' is ignored.
4554 (skip_scsh_block_comment): New function.
4556 * feature.c (scm_set_program_arguments): New argument, FIRST.
4557 * feature.h: Update prototype.
4558 * init.c (scm_boot_guile_1): Pass new argument to
4559 scm_set_program_arguments.
4561 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4563 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4564 (scm_boot_guile): Call scm_set_program_arguments here, later than
4565 the old initialization.
4567 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4568 initialization procedure.
4569 - Delete in, out, err arguments; there are other perfectly good
4570 ways to override these when desired.
4571 - Delete result argument; this function shouldn't ever return.
4572 - Rename init_func argument to main_func, for less confusion.
4573 - Delete boot_cmd argument; main_func is more general.
4574 -Add 'closure' argument, to help people pass data to main_func
4575 without resorting to global variables.
4576 - Abort if reentered; don't bother returning an error code.
4577 - Call scm_init_standard_ports to set up the default/current
4578 standard ports; no need to pass them to scm_start_stack.
4579 - Remove code to evaluate the boot_cmd, and start the repl; let
4580 the user do something like that in main_func if they want.
4581 - Remove code to package up a return value; main_func can do any
4583 - Call exit (0), instead of returning.
4584 (scm_start_stack): Don't initialize the I/O ports here; that's
4585 weird. Delete in, out, err arguments. Move guts to
4586 scm_init_standard_ports, scm_stdio_to_port.
4587 (scm_init_standard_ports): New function, to set up current and
4588 default standard ports.
4589 (scm_start_stack, scm_restart_stack): Make these static.
4590 * init.h (scm_boot_guile): Adjust declaration.
4591 (scm_start_stack, scm_restart_stack): Remove externally
4592 visible declarations for these.
4593 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4595 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4596 written out several times in scm_start_stack.
4597 * fports.h: New declaration for the above.
4599 * feature.c (scm_set_program_arguments): New function.
4600 * feature.h: New declaration for the above.
4602 * ports.c: Formatting tweak.
4604 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4606 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4607 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4608 for obtaining the address of a car or cdr field. Motivation:
4609 &SCM_CXR make assumptions about the internal structure of the
4612 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4613 Motivation: see SCM_CXRLOC.
4615 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4616 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4617 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4618 Motivation: Safer use. Some other macros are defined in terms of
4619 these operations. If these are defined using the SCM_SETCXR
4620 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4621 to inefficiency and an <e1> with side-effects could potentially
4622 break. Also, these particular operations are heavily utilized in
4623 the garbage collector. In unoptimized code there will be a
4626 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4627 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4628 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4629 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4630 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4631 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4632 vports.c: Cleaned up use of pairs: Don't make any special
4633 assumptions about the internal structure of selectors and
4634 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4635 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4636 (Among other things, this change makes it easier to build Guile
4637 with certain compilers which have problems with casted lvalues.)
4639 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4641 * stacks.c: Improve selection of relevant stack frames when making
4642 a stack object. Introduce one level of indirection in the stack
4643 object to make it possible to "narrow" to a certain region of the
4644 stack. This facilitates making use of more clever algorithms (not
4645 implemented) for selecting relevant frames and gives a cleaner
4646 design since selection of frames can be done independently of
4647 extraction of frames from the real stack.
4648 (scm_stack_id): Also take #t as argument which means look at
4651 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4652 Turn n_tail into an integer directly representing current number
4653 of frames in stack. Add field tail.
4655 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4657 * debug.c (scm_make_memoized): Made it available at scheme level.
4658 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4659 SCM_NIMP before applying heavier predicates in argument checking.
4660 (scm_local_eval): Also take memoized object as argument.
4662 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4663 aren't created with zero length, but should such a strange
4664 creature suddenly turn up...
4666 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4668 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4669 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4671 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4673 * variable.c (scm_make_variable): Make the name hint optional, as
4675 (anonymous_variable_sym): Renamed from variable_sym. All uses
4678 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4679 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4680 of scm_primitive_load_path was also changed to
4681 "primitive-load-path", from "%try-load-path". Callers changed.
4682 We'd like to respect the convention that a function named
4683 "try-mumble" should behave just like the function called "mumble",
4684 but return #f instead of signalling some error.
4685 * load.h: Rename prototypes.
4687 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4689 * print.c (make_print_state, grow_print_state), print.h: Modified
4690 the print state representation: Don't use a tail array for
4691 recording of circular references. Resizing of the print state
4692 structure invalidates the print state pointer. To avoid passing
4693 around an indirect print state reference to all printing
4694 functions, we instead let the print state reference a resizable
4697 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4699 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4700 Don't crash when passed an improper list terminated by a
4701 non-immediate value.
4703 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4705 Allocate data for structures on an eight-byte boundary, as
4706 required by the tagging system.
4707 * struct.c (alloc_struct): New function.
4708 (scm_make_struct, scm_make_vtable_vtable): Call it.
4709 * struct.h (scm_struct_n_extra_words): Bump to 3.
4710 (scm_struct_i_ptr): New "field".
4711 * gc.c (scm_gc_sweep): When we need to free the data, use the
4712 information stored by alloc_struct to find the beginning of the
4713 block allocated to the structure, so we can free it.
4715 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4717 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4720 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4721 (scm_debug_info): New member: id.
4723 * stacks.c: Stacks are now represented as structs; Stacks have an
4724 id given to them by `start-stack'.
4725 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4727 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4728 Changed stack representation.
4730 * debug.c (scm_procedure_name): Try procedure property `name' for
4731 compiled closures aswell.
4733 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4735 * eval.c: scm_i_name moved to gsubr.c
4736 (scm_m_define): Record names of all kinds of procedure
4737 objects. (Earlier, only closures were recorded.)
4739 * procprop.h: Added declaration of scm_i_name.
4741 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4742 (scm_make_gsubr): Record names of compiled closures.
4744 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4746 * debug.c, debug.h: Removed obsolete code.
4748 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4749 stacks.c: Renamed regs --> scm_contregs.
4751 * print.c (scm_free_print_state): Cleanup print state before
4752 returning it to pool. It is better to do it here than in
4753 scm_prin1 since scm_prin1 is called often.
4755 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4756 s_set_source_property_x): Check that first argument is a pair or a
4759 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4760 scm_i_line, scm_i_column and scm_i_breakpoint global.
4762 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4763 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4766 * debug.h: Added debug object smob declaration and macro
4769 * configure.in: Build with backtrace.o and stacks.o if debug
4772 * Makefile.in: Added entries for new files: backtrace.c,
4773 backtrace.h, stacks.c and stacks.h.
4775 * symbols.c (scm_sym2ovcell): Fixed documentation.
4777 * _scm.h (min, max): Added.
4779 * async.c: Moved `min' macro to _scm.h.
4781 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4782 SCM_BACKTRACE_INDENT.
4784 * eval.c: Added new debug options `maxdepth' and `indent'.
4786 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4788 * print.h: Added selector SCM_PRINT_STATE.
4790 * print.c: New functions: scm_make_print_state,
4791 scm_free_print_state.
4793 * print.h: Added declarations for scm_make_print_state,
4794 scm_free_print_state.
4796 * debug.c (scm_m_start_stack): New acro.
4798 * debug.h: Small cleanup.
4800 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4803 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4828 More prototype-related changes from Marius Vollmer:
4829 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4830 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4831 * ports.h (ptobfuns): Added prototypes. This means some casting in
4833 * fports.c: Added casts for initializations, since the functions
4834 are defined to take FILE * as their stream argument, not SCM.
4835 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4836 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4837 to `char *str_data' to conform to prototype.
4839 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4841 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4843 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4845 * stime.c, stime.h: use SCM_P method.
4847 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4849 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4850 be given at least two arguments. Insist that lst's last element
4851 be a list, but don't make any requirements of its predecessors.
4853 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4855 * eval.c (scm_nconc2last): Revert last change; there seems to be
4856 other stuff going on here.
4858 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4860 * eval.c (scm_nconc2last): Make sure that each element of lst
4861 (which is a list of argument lists, except for the tail) is a
4862 proper list, i.e., finite and terminated by '().
4864 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4866 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4869 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4870 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4873 * vectors.c (scm_make_vector): Fill vectors with the undefined
4874 value, to help make Guile Scheme code more portable to other
4877 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4878 * symbols.h, tags.h: Doc fixes.
4880 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4882 * async.c (scm_take_signal): Doc fixes.
4884 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4886 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4887 want to subtract it from the modulus; we just want to leave it
4890 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4892 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4895 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4897 * throw.c (scm_catch_apply): Finished implementation of
4900 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4902 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4904 (scm_init_filesys): set "i/o-extensions" feature.
4907 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4909 * Makefile.in (root.o): Correct dependencies.
4911 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4913 * Makefile.in: Added dependency entry for root.o.
4915 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4916 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4918 * init.c (scm_start_stack): Set initial root continuation number
4921 * procs.c: New function: scm_thunk_p.
4923 * procs.h: Added declarations of scm_thunk_p.
4925 * root.c: Renamed `call-with-new-root' -->
4926 `call-with-dynamic-root'.
4927 (cwdr): Removed allocation of new root state. This should be done
4928 separately by use of scm_make_root.
4929 (scm_apply_with_dynamic_root): New function: Does what it
4930 sounds like. Needed when spawning threads.
4932 * root.h: Added member last_debug_frame to root state.
4933 Added #include "libguile/debug.h"
4935 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4936 arguments. The motivation is that code in root.c needs catch
4937 functionality, and we want to avoid code duplication.
4938 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4939 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4940 handlers that run without popping the stack into the dynwind
4943 * throw.h: Added prototypes for scm_catch_apply and
4946 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4948 * root.h (scm_root, scm_set_root): Decouple thread support details
4949 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4950 SCM_SET_THREAD_LOCAL_DATA.
4952 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4953 and tortoise scanning loop.
4955 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4957 * Makefile.in: Rebuild dependencies.
4959 * libguile.h: #include "libguile/print.h" before "smob.h", since
4960 the latter uses the print_state structure.
4962 * throw.c (scm_ithrow): Use the correct variable when checking to
4963 see if a given element of scm_dynwinds is a valid catch.
4965 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4966 structure, abort; don't just silently ignore the garbage.
4968 * _scm.h: #include "print.h" here, since it seems to be used just
4970 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4971 strports.c, unif.h: Don't #include "print.h".
4973 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4975 * feature.h (scm_loc_features): Removed external declaration.
4976 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4978 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4980 * feature.c (scm_init_feature): Added threads feature (needs to be
4981 initialized here, since features doesn't exist when
4982 scm_init_threads is called).
4984 * libguile.h: Added #include "libguile/../threads/threads.h".
4985 (This is a kludge to get thread support working. This should be
4988 * configure.in, acconfig.h: Added flags for thread support.
4990 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4993 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4994 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4997 * _scm.h: Added conditional #include "threads.h"
4999 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5000 SCM_THREADS_SWITCHING_CODE.
5002 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5003 allocate the basic dynamic root object.
5004 (scm_boot_guile): Added call to scm_init_root.
5006 * root.c, root.h: Added root smob.
5007 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5008 functions: Implements dynamic roots mostly according to spec in
5009 SCM manual. Main difference is that the second argument is a
5010 throw handler rather than an error "thunk".
5012 * root.h: Added declaration of scm_init_root.
5014 * root.c: Added #include "genio.h", #include "smob.h", #include
5015 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5017 (scm_init_root): Added #include "root.x".
5019 * throw.c: Added #include "stackchk.h"
5020 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5021 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5022 can be used in scm_call_with_new_root; Added reenabling of stack
5023 checking when catching a throw.
5025 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5027 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5029 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5030 element is not found, as per R4RS.
5032 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5034 * list.c: Doc fixes throughout.
5036 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5038 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5039 declare the char * to be const. Avoids a warning in rgx.c.
5041 * ports.h: spelling fix.
5043 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5046 * load.c (scm_sys_try_load_path): throw an error if file not found
5047 (like it says it in NEWS).
5049 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5051 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5052 PROPS slot to '(), not #f; it's an empty alist.
5054 * throw.h, throw.c: Use SCM_P instead of #if hair.
5056 Remove special support for uncaught throws; see throw.c for
5058 * throw.c (uncaught_throw): New function.
5059 (scm_ithrow): Call uncaught_throw if we don't find a throw
5060 target; don't mess with scm_bad_throw_vcell.
5061 (scm_bad_throw_vcell): Variable deleted.
5062 (scm_init_throw): Don't initialize it.
5064 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5067 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5069 * numbers.c (scm_istr2int): If the number is short (as most
5070 numbers are), just call scm_small_istr2int to deal with it.
5071 (scm_small_istr2int): New function, created by un-#ifdefing the
5072 non-bignum version of scm_istr2int and renaming it.
5074 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5076 * load.c (scm_sys_try_load): don't check whether value returned
5077 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5078 Change the Scheme name from %try-load to primitive-load.
5080 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5081 Can avoid passing a message, allowing it to be derived in the
5082 error handler (e.g., if we want to throw to the key both from
5085 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5087 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5088 references now have a new appearance which is more compact and
5089 also gives a clue about what the target of the reference is.
5090 By setting parameters in the print state, more fancy printing can
5091 be achieved. This is used by the (not yet commited) backtrace
5094 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5096 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5099 * print.c: Added #include "struct.h". Removed function
5102 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5103 scm_iprin1. Removed prototype for scm_prlist.
5105 * arbiters.c (prinarb),
5106 async.c (print_async),
5107 debug.c (prindebugobj, prinmemoized),
5108 eval.c (prinprom, prinmacro),
5109 filesys.c (scm_fd_print, scm_dir_print),
5111 mallocs.c (prinmalloc),
5112 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5113 smob.h (scm_smobfuns),
5114 srcprop.c (prinsrcprops),
5116 unif.c, unif.h (scm_raprin1, rapr1),
5117 variable.c (prin_var): Changed argument `int writing' to
5118 `scm_print_state *pstate'.
5120 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5121 that it will be called before scm_init_print.
5123 * print.c (scm_prin1): Print states are now allocated when calling
5124 scm_prin1 and then passed around to all printing functions as an
5125 argument. A cache `print_state_pool' enables reuse of print
5127 (scm_make_print_state): New function.
5128 (scm_iprin1): Adaption to print states.
5129 (scm_iprlist): An initial "hare and tortoise" scan brings down
5130 time complexity to O (depth * N). (Better time complexity will be
5131 achieved when the printing code is completely rewritten.)
5133 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5135 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5136 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5137 it gets done whether or not the cache variable has a value.
5139 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5141 Distinguish #f and ().
5142 * __scm.h: #undef SICP.
5143 * pairs.h (SCM_EOL): Delete this definition, equating it with
5145 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5146 the value it used to have. Doc fixes, too.
5148 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5150 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5151 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5152 Lord's implementation of structs, allowing for tail arrays as
5153 described in the manual. Also fixed some bugs. (Both the interface
5154 and the implementation should be improved.)
5156 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5158 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5159 People who whish to see the source can do `(print-enable 'source)'.
5160 Removed #ifdef DEBUG_EXTENSIONS.
5162 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5164 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5165 integer (assuming for now accepting an integer is a good thing).
5167 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5168 %S will be used instead for write'ing arguments.
5170 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5171 asserts. fix a few other asserts.
5172 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5173 scm_uniform_vector_ref, scm_array_set_x,
5174 scm_dimensions_to_unform_array): change args in
5175 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5176 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5177 scm_substring_fill_x): likewise.
5178 gsubr.c (scm_gsubr_apply): likewise.
5179 eval.c (SCM_APPLY): likewise.
5181 * eval.c (4 places): replace scm_everr with lgh_error or
5184 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5185 scm_memory_error): new procedures.
5186 scm_everr: deleted. can use scm_wta, dropping first two args.
5187 scm_error: convert NULL subr to SCM_BOOL_F.
5189 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5192 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5195 * error.c, error.h: new error keys: scm_arg_type_key,
5196 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5198 scm_wta: reimplement using lgh_error instead of scm_everr.
5200 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5202 * gdbint.c: scm_lread now has one more argument.
5204 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5205 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5206 loading source from non-file ports, which, e. g., happens when
5207 using the Emacs interface).
5209 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5212 * read.c: Added code for recording of positions of source code
5213 expressions; New functions: recsexpr, scm_lreadrecparen;
5214 _scm_make_srcprops --> scm_make_srcprops
5215 (scm_flush_ws): Removed updating of positions counters. This work
5216 is already done by scm_gen_getc
5218 * read.h: Added prototype for scm_lreadrecparen
5220 * print.c: Added #include "alist.h"
5222 * eval.c: Added #include "hash.h"
5224 * eq.c: Added #include "ramap.h"
5226 * options.c: Documentation fixes.
5228 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5229 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5230 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5231 --> scm_make_srcprops
5233 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5234 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5235 function calls in the definition of the whash access macros.
5237 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5239 * init.c (scm_boot_guile): Add level of indirection to
5240 scm_boot_guile_1() to ensure that stack base pointer is properly
5241 initialized. There was no guarantee that variable i was the
5242 highest/lowest variable on stack (i.e. the call frame of
5243 scm_boot_guile was not completely protected from gc).
5245 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5247 * ports.h (scm_port_table): put back file_name, it will be used to
5248 support debugging. Undo related changes in fports.c, ioext.c,
5251 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5253 * ports.h (scm_port_table): remove file_name member for now, it seems
5255 * fports.c (scm_open_file): don't set file_name in PTAB.
5256 (prinfport): don't use file_name in PTAB.
5257 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5258 * ports.c (scm_add_to_port_table): don't intialize file_name.
5259 (scm_port_file_name): remove for now.
5260 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5262 * fports.h (scm_mkfile): prototype deleted.
5263 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5265 * debug.c, unif.c: use scm_out_of_range instead of
5266 wta for range errors (ASSERT still needs work).
5268 * error.c, error.h (scm_out_of_range): new procedure.
5270 * error.c, error.h (scm_out_of_range_key): new key.
5272 * posix.c (scm_sync): #else was missing.
5274 * error.c, error.h: append _key to names scm_num_overflow and
5277 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5278 of consing an empty list.
5279 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5280 of macros, saves code and string space.
5281 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5282 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5283 lower case. Rename scm_syserror_m to scm_syserror_msg.
5284 error.h: prototypes for new procedures.
5286 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5288 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5290 * error.c, error.h: setup scm_num_overflow key.
5292 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5293 Remove definition of SCM_OVSCM_FLOW.
5295 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5297 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5298 explicit message and args.
5300 * error.c, error.h, __scm.h: change system_error_sym to
5303 * error.c (system_error_sym): remove leading %% from the Scheme name
5306 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5308 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5310 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5311 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5312 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5313 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5314 renamed. (These were introduced by unsupervised name
5317 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5319 * print.c: Added code for detection of circular references during
5320 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5321 a hook for printing of closures (accessible via print options).
5322 This leads to a split of calls to scm_iprin1 into two classes:
5323 elementary print operations (e. g. the code which prints a smob)
5324 still use scm_iprin1 while top level calls (like scm_display) use
5325 scm_prin1. scm_prin1 begins by clearing the data structure used
5326 to record reference information.
5328 * print.h: Added declarations of scm_prin1 and scm_prlist.
5330 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5332 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5334 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5336 * error.c (err_head): scm_iprin1 --> scm_prin1
5338 * debug.c: Adjusted header comment.
5342 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5344 * strerror.c: Doc fix.
5346 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5348 * gdbint.c (gdb_read): Now possible to run during GC.
5349 (unmark_port, remark_port): New functions.
5351 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5353 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5354 of allocating a new string object. Also, increase size by
5355 the factor 2 instead of 1.5.
5357 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5359 * __scm.h (SCM_P): Corrected to run under traditional C.
5361 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5364 * async.c: Calls to scm_sysintern corrected.
5366 * async.h (scm_async_clock): Redundant declaration removed.
5368 * continuations.c (scm_dynthrow): Redundant declaration removed.
5370 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5371 Definition typos corrected.
5373 * debug.h: Missing declarations of functions in debug.c added
5376 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5377 Missing declarations to functions in eval.c added.
5379 * filesys.c: Possibly uninitialized variable rv.
5381 * gc.h (scm_object_addr, scm_unhash_name): Missing
5382 declarations of functions defined in gc.c added.
5384 * genio.c: Possible typos str_data -> wstr_data. ???
5386 * genio.c: Possibly unintended shadowing of local variable
5387 `int c' (gotos out of scope of inner `c'). ???
5389 * init.c: Uninitialized `SCM last' may be used.
5391 * ioext.h: (scm_sys_isatty_p): Typo.
5393 * list.h (scm_list_head): Missing prototype for function in
5396 * numbers.c (scm_two_doubles): Changed from extern to static
5397 (is used only within numbers.c).
5399 * numbers.h: Repeated declarations removed.
5401 * ports.h (scm_close_all_ports_except): Declaration for the
5402 function defined in ports.c added.
5404 * posix.h: Missing declarations added.
5406 * procs.h (scm_make_subr_opt): Missing declaration added.
5408 * socket.h (scm_sys_gethost): Missing declaration added.
5410 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5412 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5413 Missing declarations added.
5415 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5417 * struct.c: Uninitialized variable `SCM answer' may be used.
5419 * unif.c (l2ra): Declaration prototype.
5421 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5422 defined in ramap.c).
5424 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5425 Redundant declarations removed (they are in ramap.h).
5427 * variable.h (scm_make_udvariable,
5428 scm_make_undefined_variable): Declaration corrected to
5429 correspond variable.c.
5431 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5432 Missing declarations added.
5434 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5436 * Makefile.in (distclean): Don't forget to delete fd.h.
5438 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5440 * fd.h.in, tags.h: Trivial cleanups.
5442 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5443 marksweep.h just declared functions from gc.c.
5444 * gc.h, libguile.h: Don't #include "marksweep.h".
5445 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5446 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5447 dependencies updated.
5449 * libguile.h: Don't #include "files.h"; it's been deleted.
5451 * files.c (scm_sys_delete_file): Moved to filesys.c.
5452 File is now empty; deleted.
5454 * filesys.c: scm_sys_delete_file is now here. Remove
5455 #if's; they seem to rely on remnants of an old portability
5456 regimen. If the problems come up again, solve them properly,
5457 using autoconf. Specifically: Don't test M_SYSV, and #define
5458 remove to be unlink if it's #defined; don't use remove just
5459 because HAVE_STDC_HEADERS is #defined.
5460 * filesys.h: Add declarations for scm_sys_delete_file.
5461 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5462 files.o, files.h, files.c, and files.x.
5463 * init.c: Don't #include "files.h", and don't call scm_init_files.
5465 Use SCM_P instead of PROTO; the latter intrudes on the user's
5467 * params.h: Deleted; definition of SCM_P moved to...
5468 * __scm.h: ... here, where it replaces PROTO macro.
5469 * libguile.h, smob.h: Don't #include "params.h".
5470 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5471 smob.h: Fix prototypes accordingly.
5472 * Makefile.in: Update dependencies.
5473 (inner_h_files): Remove params.h.
5475 * gc.c: #include "gc.h"; every module should include its header,
5476 to let the compiler cross-check the declarations against the
5479 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5480 simpos.h: #include "libguile/__scm.h".
5482 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5484 * init.c: Don't forget to #include smob.h and init.h.
5485 * Makefile.in: Dependencies updated.
5487 * smob.h: Use PROTO instead of #if __STDC__.
5489 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5491 * __scm.h: Doc fixes.
5493 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5494 <angles>; this allows `make depends' to work properly.
5496 * libguile.h: #include smob.h and pairs.h before the others; they
5497 define typedefs used by other headers.
5499 C files should #include only the header files they need, not
5500 libguile.h (which #includes all the header files); the pointless
5501 recompilation was wasting my time.
5502 * Makefile.in (all .o dependency lists): Regenerated.
5503 * libguile.h: Don't try to get a definition for size_t here...
5504 * __scm.h: Do it here.
5505 * _scm.h: Since this is the internal libguile header, put things
5506 here that all (or a majority) of the libguile files will want.
5507 Don't #include <libguile.h> here; that generates dependencies on
5508 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5509 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5510 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5606 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5607 * weaks.c: Get "weaks.h".
5609 * stackchk.h: #include "libguile/debug.h",
5611 * print.h, read.h: #include "options.h", since everyone who uses
5612 either of these files will need that.
5614 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5615 anyone who uses this file will need them to define the smob
5616 printing functions. Also, get markers.h, since people will need
5617 to #define the mark functions.
5619 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5620 * ports.h: ... to here.
5622 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5623 don't rely on archaic C default type rules.
5625 * fports.h: #include "libguile/ports.h", since you need that in
5626 order to parse this.
5628 * genio.h: #include "libguile/print.h", because you need that to
5629 parse this; don't bother #including "ports.h", since print.h gets
5632 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5634 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5635 this; it's now a reference to an element of *scm_root.
5637 * debug.h: Don't #include "options.h"; the compiler won't be able
5638 to find that once the headers are installed; instead, #include
5639 "libguile/options.h".
5640 * gc.h: Same, with marksweep.h.
5641 * mbstrings.h: Same, with symbols.h.
5642 * scmhob.h: Same, with _scm.h.
5643 * smob.h: Same, with params.h.
5645 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5646 C files; there's no need for this, and it forces recompilations
5649 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5651 * error.c (scm_error): declare scm_error_callback.
5653 * error.h: prototype for scm_error_callback.
5655 * __scm.h: define lgh_error.
5656 (SCM_SYSERROR): redefine using lgh_error.
5658 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5660 * error.c (scm_error): new procedure.
5662 * error.h: prototype for scm_error.
5664 * Makefile.in (install): install scmconfig.h from the current
5665 directory, not $(srcdir).
5667 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5669 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5670 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5671 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5677 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5678 vports.h, weaks.h: #include "libguile/__scm.h", not
5679 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5680 dependencies are within libguile properly.
5682 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5684 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5685 when scmconfig.h doesn't exist.
5687 * load.c (scm_sys_try_load): Correct spelling.
5689 * feature.c (scm_loc_features): Make this static.
5691 * Makefile.in (libpath.h): Omit trailing slash from path. We
5692 shouldn't require it of users, so why put it here?
5694 Move code to initialize and search %load-path from ice-9 to C
5695 code, so we can use the load-path to find the ice-9 boot code;
5696 this makes it easier to run Guile without installing it. See
5697 corresponding changes in guile/Makefile.in.
5698 * feature.c: Move stuff concerned with the load path to load.c.
5699 (scm_compiled_library_path): Deleted.
5700 Don't #include libpath.h here.
5701 * feature.h: Don't mention scm_compiled_library_path.
5702 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5703 <sys/stat.h>, and <unistd.h> (if present).
5704 (R_OK): #define if the system hasn't deigned to.
5705 (scm_loc_load_path): New variable.
5706 (scm_init_load_path, scm_sys_search_load_path,
5707 scm_sys_try_load_path): New functions.
5708 (scm_init_load): Initialize scm_loc_load_path to point to the
5709 value cell of the Scheme %load-path variable.
5710 * load.h: Add declarations for scm_sys_search_load_path,
5711 scm_sys_try_load_path.
5712 * init.c: Call scm_init_load_path.
5713 * Makefile.in (feature.o, load.o): Dependencies updated.
5715 * load.c, load.h: Rewrite using PROTO macro.
5717 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5719 * gc.c (scm_cellp): New function: C predicate to determine if an
5720 SCM value can be regarded as a pointer to a cell on the heap.
5722 * gc.h: Added declaration of scm_cellp.
5724 * gdb_interface.h: New file: The GDB interface header from the GDB
5727 * gdbint.c: New file: GDB interface.
5729 * gdbint.h: New file: GDB interface.
5731 * libguile.h: Added #include <libguile/gdbint.h>.
5733 * init.c (scm_boot_guile): Added scm_init_gdbint.
5735 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5736 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5737 found if object files and source are kept separate).
5739 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5741 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5743 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5745 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5746 TK_SRC_DIR; they're not relevant any more.
5748 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5749 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5751 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5753 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5754 search path, so we can find the <libguile/MUMBLE.h> headers.
5756 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5758 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5759 implicit in the .c.o rule.
5760 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5763 Put the library path in a header file, instead of passing it on
5764 the command line in every compilation.
5765 * Makefile.in (libpath.h): New target.
5766 (feature.o): Depend on libpath.h.
5767 (clean): Delete libpath.h.
5768 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5769 * feature.c: ... #include "libpath.h" here.
5770 * .cvsignore: Ignore libpath.h.
5772 Don't install the unwashed masses of Guile header files in the
5773 main #include path; put most of them in a subdirectory called
5774 'libguile'. This avoids naming conflicts between Guile header
5775 files and system header files (of which there were a few).
5776 * Makefile.in (pkgincludedir): Deleted.
5777 (innerincludedir): New variable; this and $(includedir) are enough.
5778 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5779 (installed_h_files): Divide this up. Now this variable lists
5780 those header files which should go into $(includedir) (i.e. appear
5781 directly in the #include path), and ...
5782 (inner_h_files): ... this new variable says which files appear in
5783 a subdirectory, and are referred to as <libguile/mumble.h>.
5784 (h_files): List them both.
5785 (install): Create innerincludedir, not pkgincludedir. Put
5786 the installed_h_files and inner_h_files in their proper places.
5787 (uninstall): Corresponding changes.
5788 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5789 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5790 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5791 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5792 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5793 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5794 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5795 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5796 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5797 vports.h, weaks.h: Find __scm.h in its new location.
5798 * __scm.h: Find scmconfig.h and tags.h in their new locations
5799 (they're both "inner" files).
5801 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5803 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5805 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5807 * posix.c: Doc fixes.
5809 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5811 * socket.c: Don't include a prototype for inet_aton; just use a
5812 K&R style declaration, to avoid warnings but minimize the chance
5813 of conflicts with the system.
5815 On NextStep, <utime.h> doesn't define struct utime, unless we
5816 #define _POSIX_SOURCE before #including it.
5817 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5818 * acconfig.h: New comment text for above CPP symbol.
5819 * configure.in: Call it.
5820 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5822 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5824 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5825 testing for __EMX__.
5827 * posix.c: #include <libc.h>, if it exists.
5829 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5830 don't even know if the latter exists.
5832 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5833 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5834 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5836 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5838 (scm_init_posix): Use them when initializing the Scheme constants
5841 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5843 * Makefile.in (libdir, includedir, bindir): Use the
5844 autoconf-supplied values, instead of deriving them ourselves.
5845 (pkgincludedir, datadir, pkgdatadir): New variables.
5846 (install, uninstall): Put the header files in a special
5847 subdirectory, not in the main search path.
5849 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5850 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5852 * Makefile.in (IMPLPATH): Deleted; never used.
5854 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5855 on the Tcl/Tk source any more.
5856 (INCLUDE_CFLAGS): Remove references to the above.
5858 * Makefile.in (version.o): Corrected dependencies.
5860 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5862 * libguile.h: #include "version.h"
5864 * init.c (scm_boot_guile): Call scm_init_version.
5865 * gscm.c (gscm_run_scm): Call scm_init_version.
5867 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5868 GUILE_VERSION): AC_DEFINE these.
5869 (acconfig.h): #undef the above symbols.
5871 * Makefile.in (libobjs): Add version.o.
5872 (installed_h_files): Add version.h.
5873 (c_files): Add version.c.
5874 (gen_c_files): Add version.x.
5875 (version.o): New rule.
5876 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5877 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5878 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5879 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5880 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5881 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5882 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5883 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5884 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5885 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5886 weaks.o): Add version.h to dependency lists.
5887 (markers.o): Remove duplicate rule.
5889 * version.h: New file.
5891 * version.c: New file.
5893 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5895 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5896 array; use it appropriately. Since GCC is quite happy to
5897 subscript functions, it never warned us about this; we should use
5898 -Wpointer-arith in the future. I guess we never tested
5901 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5903 * socket.c: Doc and copyright fixes.
5905 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5907 * debug.c: Fixed and improved gdb support.
5909 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5911 * socket.c: Added declaration of inet_aton to avoid compiler
5912 warning. (Hope this solution is correct.)
5914 * stime.c: Added declaration of ftime. (This is missing in
5917 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5919 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5921 * Makefile.in (c_files): add strerror.c.
5923 * strerror.c: new file from Emacs' sysdep.c.
5924 maybe configure should also check for sys_errlist.
5926 * configure.in (AC_REPLACE_FUNCS): add strerror.
5928 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5930 * debug.c (scm_init_debug): Added initialization for
5931 scm_evaluator_traps.
5933 * debug.h, debug.c: Various name changes.
5934 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5935 "debug-options-interface". See commentary in options.c.
5937 * options.h, options.c: Options now have documentation strings.
5938 Also added a long explanatory commentary.
5940 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5943 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5944 last_debug_info_frame is now updated in all cases.
5946 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5949 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5951 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5952 Added option STACK_CHECKING.
5954 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5956 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5958 * __scm.h: Removed symbols for debugging support.
5960 * acconfig.h: Added symbols for debugging support.
5962 * configure.in: Added user option for debugging support.
5963 --enable-debug will include the debugging code into libguile.a.
5965 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5966 scm_relocate_chunk_to_heap.
5968 * debug.c: New file: low-level debugging support. It also
5969 includes support for debugging with gdb. (The extensions to gdb
5970 are written by Per Bothner at Cygnus.)
5972 * debug.h: New file: low-level debugging support.
5974 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5975 argument pairs. Extensive modifications to the debugging
5976 evaluator. Added "SECTION:" commentaries to clarify what happens
5977 when, during double compilation. Renamed EVALIMP --> EVALIM.
5978 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5979 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5980 the beginning of the file. New procedure: scm_unmemocopy.
5981 Added some global state variables needed by the debugging
5982 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5983 check_entry, check_apply, check_exit, debug_options and
5984 evaluator_traps. New acro: undefine.
5986 * eval.h: Renamed EVAL --> XEVAL.
5988 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5989 --> scm_make_weak_key_hash_table.
5991 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5992 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5994 * libguile.h: Conditionally include debug.h
5996 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5997 scm_object_properties shouldn't return handle. `handle' now gets
5998 initialized in scm_set_object_properties_x. scm_object_properties
5999 doesn't any longer create an entry in scm_object_whash.
6001 * options.c: New file: handling of run time options.
6003 * options.h: New file: handling of run time options.
6005 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6007 * print.c: New procedure: scm_print_options
6009 * print.h: Defines for print options.
6011 * read.c: New procedure: scm_read_options
6013 * read.h: Defines for reader options.
6015 * root.h: Added scm_source_whash among scm_sys_protects.
6017 * srcprop.c: New file: source properties.
6019 * srcprop.h: New file: source properties.
6021 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6022 (Bug found by A. Green.)
6024 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6026 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6028 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6030 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6032 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6033 and should be called by the final client.
6035 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6037 * gc.h: Use the PROTO macro when declaring functions.
6038 * gc.c: Use the PROTO macro when declaring static functions.
6039 Remove the CPP hair around function definitions.
6041 * gc.c (scm_init_storage): Initialize scm_asyncs.
6043 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6044 preprocessor symbol; "__scm.h" is where it might get #defined.
6045 * __scm.h: Similar: #include <scmconfig.h> before testing
6048 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6050 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6052 * init.c (scm_boot_guile): Add init_func argument; call
6053 (*init_func) instead of calling scm_appinit; it's ucky to
6054 hard-code names for the user's procedures.
6055 * init.h (scm_boot_guile): Adjust declaration.
6057 * __scm.h (PROTO): New macro, for declaring functions with
6060 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6061 eliminate all the __STDC__ conditionals.
6062 (scm_boot_guile): Add declaration.
6063 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6064 Remove __STDC__ conditionals around function definitions; the
6065 declarations in init.h will provide the same information, more
6068 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6069 complain about it in the error message; the error message is
6070 adequate without that note, and there's nothing the user can do
6073 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6075 * Makefile.in (ancillary): Drop def.sed.
6077 * posix.c (scm_init_posix): Use numeric values, rather than
6078 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6079 F_OK. The symbols aren't available on some systems, and I'm
6080 pretty sure their values are fixed by common widespread practice.
6081 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6083 More functions unavailable on some systems.
6084 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6085 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6087 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6088 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6089 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6090 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6091 stub that signals an error as the #else.
6093 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6095 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6097 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6099 * unif.c: include ramap.h.
6101 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6103 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6105 * ports.c: include sys/ioctl.h.
6107 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6109 * configure.in: check for sys/ioctl.h.
6111 * ports.c: include <malloc.h> not "malloc.h".
6113 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6115 * fports.c: remove ttyname and tmpnam declarations.
6117 * posix.c: fewer ttyname declarations.
6119 * fports.c: include <string.h> not "string.h".
6121 * init.c, ioext.c: include string.h and unistd.h.
6123 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6125 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6126 genio.c, simpos.c, vports.c: include string.h.
6128 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6130 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6132 (scm_addr_buffer_size): change type from scm_sizet to int.
6133 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6134 from scm_sizet to int.
6136 * error.c: include unistd.h.
6138 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6141 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6143 * __scm.hd, def.sed: deleted.
6145 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6147 Changes for NeXT, suggested by Robert Brown.
6148 * configure.in: Call AC_TYPE_MODE_T.
6149 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6150 NeXT. Put header file list in alphabetical order.
6151 * configure, scmconfig.h.in: Regenerated.
6152 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6154 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6157 * acconfig.h: New file, providing documentation for the CPP
6158 symbols defined in configure.in
6159 * acconfig-1.5.h: Removed; superceded by the above.
6161 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6163 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6165 * fports.c (scm_open_file): don't return #f, throw error.
6167 * ioext.c (fileno): renamed from %fileno.
6168 (soft-fileno): deleted.
6170 * ports.c (scm_port_revealed): don't need to check for -1 from
6172 (scm_set_port_revealed_x): return unspecified, not #f.
6174 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6176 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6178 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6180 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6182 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6184 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6185 This is necessary on Ultrix, and doesn't hurt portability.
6187 * Makefile.in (dist-dir): New target, implementing a new dist system.
6188 (installed_h_files): Put in alphabetical order.
6189 Remove duplicate entries for markers.h and unif.h.
6190 (c_files): Remove duplicate entries for markers.c.
6191 (ancillary): Renamed from anillery; all uses changed. Remove
6192 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6193 Remove all the ../doc/* files; doc/Makefile.in handles that.
6195 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6197 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6198 every if must have an else, or else the whole command has a
6199 non-zero exit code whenever the if's condition is false.
6201 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6203 * posix.c: include string.h.
6205 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6207 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6210 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6211 Remove leading % from scheme names.
6212 Do not return error values, call SCM_SYSERROR or similar.
6214 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6216 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6218 * struct.c (scm_init_struct): new file.
6220 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6222 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6223 (scm_list_head): added list-head for rapidly chopping argument
6224 lists off of longer lists (and similar).
6226 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6228 * objprop.c (scm_object_property): assq the cdr of the whash
6229 handle for obj, not the handle itself.
6231 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6233 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6234 weak hash tables last of all marking to avoid an obscure gc bug.
6235 WARNING: circular lists stored in a weak hash table will hose us.
6237 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6239 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6240 new functions similar to scm_substring_move_left_x and
6241 scm_substring_move_right_x.
6243 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>

6458 initialization to fix a race condition.
6460 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6487 The weird symbol syntax is also a bit bogus (emacs doesn't quite
