1 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * debug.c (scm_debug_options): Bugfix: Set the value of
4 scm_stack_checking_enabled_p after setting debug options;
5 #include "stackchk.h". (Thanks to Richard Polton.)
7 1998-11-13 Radey Shouman <rshouman@metro2000.com>
9 * unif.c (scm_array_contents): removed unnecessary test for 0
12 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
14 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
15 Replaced by macro `collect' in boot-9.scm.
17 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
19 * eval.c (scm_copy_tree): Copy source properties if existent.
21 * debug.c (scm_start_stack): Copy source when evaluating. (If we
22 don't, we may end up passing memoized source to a transformer.)
24 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
26 * stack.c (get_applybody): Help function which lookups the first
27 body form of the apply closure.
28 (read_frames): Prevent the source of the first form of the apply
29 closure from being recorded. This would only be confusing.
31 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
32 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
34 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
36 * stacks.c (read_frame): Bugfix: Removed lingering `else'
38 (read_frames): Use SCM_MACROEXPP.
40 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
42 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
43 don't contain interesting information since all arguments are
44 present in the frame which applies the compiled closure anyway.);
45 Skip the transformer application frames.
47 * print.c (scm_iprin1): Print gsubrs as primitives.
49 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
51 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
53 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
54 that we can identify these in a backtrace. (This change doesn't
55 introduce any significant speed penalty.)
57 * eval.c: Added note about `serial-map' using scm_map.
59 * read.c, read.h (scm_read_options, scm_read_opts): Removed
60 readline options. They should reside in their own options array.
62 * readline.c, readline.h (scm_readline_options,
63 scm_readline_opts): Moved readline options here.
65 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
67 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
68 SCM_ROCHARS instead of SCM_CHARS.
70 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
71 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
73 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
75 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
76 This is quite important since the latter clears the
77 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
78 every single character read...
80 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
82 * print.c (scm_iprin1): Removed suspect looking (and indeed
83 malevolent) semicolon after test for user supplied closure print
84 procedure. (Thanks to Telford Tendys.)
86 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
87 (scm_memq, scm_memv, scm_member): Do argument checking *before*
88 starting to search the list. Removed call to sloppy_mem_check.
90 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
91 procedures: Same as scm_delq_x et al, but delete maximally one
94 * options.c (scm_options, scm_init_options): GC-protect option
95 values of type SCM. (Thanks to Telford Tendys.)
97 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
99 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
100 make sure that there always is a "real" scm_lookupcar.
102 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
104 * read.c, read.h (history-length, history-file): New read options.
105 (scm_read_options): Stifle history to history length.
107 * readline.c (scm_read_history, scm_write_history): New
110 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
112 * eval.h (scm_macro_eval_x): Removed declaration.
114 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
115 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
116 Renamed and made global.
118 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
119 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
121 * evalext.c, evalext.h: New files. Contain non-R5RS things
122 having to do with evaluation.
124 * evalext.c (scm_serial_map): New procedure: Version of `map'
125 which guarantees that the procedure is applied to the lists in
127 (scm_m_sequence_to_list): New syntax: Version of `begin' which
128 returns a list of the results of the body forms instead of the
129 result of the last body form.
130 (scm_definedp, scm_m_undefine): Moved from eval.c
132 * evalext.h (scm_m_sequence_to_list): Added declaration.
134 * macros.c, macros.h: New files.
135 (scm_procedure_to_syntax, scm_procedure_to_macro,
136 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
137 scm_macro_name, scm_macro_transformer): Moved from eval.c
138 (scm_make_synt): Moved from eval.c
140 * procs.c, procs.h (scm_procedure_documentation): Moved from
143 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
146 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
148 * debug.c, print.c: Added #include "macros.h".
150 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
152 This change adds the ability to use `unread-char' multiple times
153 without interspersed reads and adds the new procedure
154 `unread-string'. The change is optimized for the common case of
155 unreading a single character. This is also the reason behind the
156 choice to store characters in the port itself: in most cases no
157 extra malloc is required.
159 The amount of code in some macros in ports.h has been increased to
160 the extent that they would fit better as C functions, but, since
161 this code belongs to the port representation, such functions
162 should be placed in ports.c which would cause calls back and forth
163 between ports.c and genio.c. That is not good for performance.
164 Also, keeping them as macros allows the compiler to do some
165 optimizations which are needed to make the current interface
166 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
168 One benchmark (Guile startup time) indicates an increase of
169 loading speed of 1%. Another (reading (using `read') boot-9.scm
170 10 times) shows no change in performance.
172 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
173 made to find a beautiful solution.)
175 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
176 (SCM_TRY_CLRDY): New macro: Only clear the first unread
177 character. (SCM_CLRDY clears all.)
178 (SCM_N_READY_CHARS): New macro: Returns number of unread
179 characters in a port. Returns wrong answer if SCM_CRDYP is false.
180 (struct scm_port_table): New fields: `entry' contains port table
181 index, `cp' points to last unread char, `cbuf' is the buffer for
182 unread chars, `cbufend' points after end of the character buffer.
184 * ports.h, ports.c (scm_unread_string): New procedure.
185 (scm_grow_port_cbuf): New function.
187 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
189 (scm_generic_fgets), fports.c (local_fgets): Use a loop
190 to read unread characters. Use SCM_TRY_CLRDY instead of
193 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
195 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
197 * genio.c, genio.h (scm_ungets): New function.
199 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
202 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
204 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
205 declarations. (Thanks to Russ McManus.)
207 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
209 * numbers.c (num2long): As a software archeologist, I'm proud of
210 this finding! :) Preliminary dating suggests an almost 4 year old
211 remnant from the SCM ancestor. The sample has been removed from
212 the finding site and is now safely stored in the repository.
214 * numbers.h: Removed prototype for num2long.
216 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
218 * gh_data.c (gh_scm2doubles): Make it possible to pass result
220 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
221 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
222 * gh.h: Updated and added prototypes.
224 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
226 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
228 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
230 * guile-snarf.in: Never generate an empty file. (Thanks to
233 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
234 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
235 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
236 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
237 gh_new_procedure5_0): Specify argument types, to appease C++
238 compilers. (Thanks to Brad Bowman.)
240 Bug reports from Russ McManus:
241 * guile-snarf.in: If the CPP environment variable is set, use that
242 as the C preprocessor, instead of the preprocessor autoconf
244 * snarf.h (SCM_PROC): Cast the function pointer passed to
245 scm_make_gsubr, to satisfy C++.
247 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
248 Use the handler passed, instead of ignoring it and using
249 gh_standard_handler. (Thanks to Etienne Bernard.)
251 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
253 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

276 * script.c (scm_compile_shell_switches): Define
277 use-emacs-interface in the root module, so the repl code can see
278 it. See today's change to top-repl in ice-9/boot-9.scm.
280 * filesys.c (set_element, get_element): Make sure that `element'
281 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
282 Boekemeier and Jorgen "forcer" Schaefer.)
284 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
286 * chars.c (scm_charnames): In ASCII character name table, make
287 newlines print as #\newline by default, not #\nl.
289 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
290 alphabetical order. Oh thrills. But it helps me know how far
291 along in the compilation I am.
292 * Makefile.in: Regenerated.
294 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
296 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
297 #bytes(...) to #y(...), and syntax for short vectors from
298 #short(...) to #h(...). This may seem nutty, but, like the other
299 uniform vectors, byte vectors and short vectors want to have the
300 same print and read syntax (and, more basic, want to have read
301 syntax!). Changing the read syntax to use multiple characters
302 after the hash sign breaks with the conventions used in R5RS and
303 the conventions used for the other uniform vectors. It also
304 introduces complexity in the current reader, both on the C and
305 Scheme levels. (The Right solution is probably to change the
306 syntax and prototypes for uniform vectors entirely.)
308 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
310 Don't use local_fgets on sockets; ftell doesn't work on sockets.
311 (Thanks to Jorgen "forcer" Schaefer.)
312 * ports.h (SCM_NOFTELL): New flag.
313 * fports.c (local_fgets): If it's set, use the generic fgets.
314 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
316 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
318 * script.c (scm_compile_shell_switches): Add handling of -q switch
319 (inhibit loading of user init file).
320 (scm_shell_usage): Add usage text for -q switch.
321 (scm_compile_shell_switches): Always load user init file first if
324 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
326 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
327 and is now broken under NetBSD. I can't fathom what it's trying
328 to do, so I've replaced it with something that I do understand,
329 which seems to work, and which isn't broken on NetBSD. "Progress?
330 You Decide." (Thanks to Perry Metzger.)
332 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
333 signed/unsigned comparison.
335 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
337 Warning fixes from Greg Harvey:
338 * unif.c (scm_array_set_x): initializer for pos
339 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
340 * struct.c (scm_struct_ref, scm_struct_set_x): Added
341 initializers for field_type, since EGCS so desparately wants to
343 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
344 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
345 when GUILE_DEBUG is defined.
346 * dynwind.h (scm_wind_chain): Same.
347 * ports.h (scm_pt_size, scm_pt_member): Same.
348 * print.h (scm_current_pstate): Same.
349 * procs.h (scm_make_cclo): Same.
351 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
353 Handle short and long long uniform arrays properly. (Thanks to
355 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
356 raeql_1): Add cases for scm_tc7_svect (short vectors) and
357 scm_tc7_llvect (long long vectors).
359 Change the way libguile and boot-9.scm are timestamped, to try to
360 get rid of these spurious mismatch warnings. Now both
361 libguile/versiondat.h and ice-9/version.scm are generated directly
362 by the configuration process, rather than having version.scm
363 generated directly, and libguile/versiondat.h generated by the
364 Makefile, which is generated by configure. It seems that
365 sometimes the Makefile would change, but versiondat.h depends on
366 Makefile.in, not Makefile, so it wouldn't get rebuilt.
367 * Makefile.am (versiondat.h): Target removed; this is generated
368 directly by the configure script now.
369 (BUILT_SOURCES): Remove versiondat.h.
370 * versiondat.h.in: New file, transformed by the configure script
372 * Makefile.in: Regenerated.
374 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
375 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
376 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
377 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
378 if we want to use them in a header file some day, we can. (Thanks
381 * stime.c (scm_get_internal_real_time): Do the arithmetic using
382 SCM numbers, so we won't have rollover problems; the range of a
383 signed long in milliseconds is about 25 days. (Thanks to Karl
386 Don't redefine sleep and usleep; fix this problem now.
387 * coop.c (sleep, usleep): Remove declarations; we don't use or
388 redefine these any more.
389 (scm_thread_usleep, scm_thread_sleep): New functions which do the
390 job of usleep and sleep in a thread-friendly way. We can use
391 these in the rest of Guile. Define versions for systems both with
393 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
394 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
395 we're just using it, not redefining it, we can use a K&R style
397 (sleep): Declare this, too, if the system hasn't.
398 (scm_sleep, scm_usleep): Use scm_thread_sleep and
399 scm_uthread_sleep if they're available; otherwise, just call the
401 * scmconfig.h.in: Regenerated.
403 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
405 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
407 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
409 * threads.c: Doc fix.
411 The argument type of usleep varies from system to system,
412 as does the return type. We really shouldn't be redefining usleep
413 at all, but I don't have time to clean that up before the 1.3.
414 release. It's on the schedule for afterwards. (Thanks to Julian
416 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
418 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
419 * scmconfig.h: Regenerated.
421 * simpos.c (scm_software_type): Procedure deleted. This isn't the
422 right way to handle system variation. Autoconf's approach is the
424 * simpos.h (scm_software_type): Declaration deleted.
426 * script.c (scm_find_executable): Don't test if unix is #defined
427 here; first, NetBSD doesn't #define it, and second, it's the wrong
428 way to go about these things. (Thanks to Perry Metzger.)
429 (dld_find_executable): Delete this MSDOS support code. This isn't
430 the way we want to support this; it needs to be rethunk at a
433 * genio.c (scm_do_read_line): Don't just politely check that the
434 line was either non-empty or EOF. Abort if it's empty and not
437 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
439 * scmconfig.h.in: Regenerated.
441 * libguile.h: Don't omit the dynamic linking functions. (Thanks
444 * genio.c (scm_do_read_line): Count lines correctly when the file
445 doesn't end in a newline.
447 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
449 * genio.c (scm_do_read_line): Maintain the line count correctly.
450 (Thanks to Harvey J. Stein and Greg Harvey.)
452 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
455 * numbers.c (big2str): Protect t from garbage collection until
456 we're done. (Thanks to Gary Houston.)
458 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
460 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
462 * Makefile.in: Regenerated.
464 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
465 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
468 Do magic to mix reads and writes on stdio FILE-based ports.
469 (Thanks to Christian Lynbech.)
470 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
472 (pre_read, pre_write): New functions.
473 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
474 local_fputs): Call them.
475 (local_fflush): Mark the port as ready for reading and writing.
476 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
477 flags on new port objects. This might not be accurate --- who
478 knows what state the FILE * is in when we get it --- but it won't
479 do extraneous calls to fflush or fseek, so it's no worse than the
480 behavior before this change.
481 * ports.h: Add comment.
483 Centralize the creation of port objects based on stdio FILE * in
484 fports.c; don't just throw them together anywhere.
485 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
486 what the rest of Guile wants. Don't set the revealed count;
487 that's only appropriate for stdin, stdout, stderr.
488 (scm_standard_stream_to_port): This function does set the revealed
490 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
491 not scm_stdio_to_port.
492 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
493 * fports.c (scm_open_file): Same.
494 * posix.c (scm_pipe): Same.
495 * socket.c (scm_sock_fd_to_port): Same.
496 * ioext.c (scm_fdopen): Same.
497 (scm_freopen): Moved from here to...
498 * fports.c (scm_freopen): ... here. This is really something that
499 munges the internals of an fport, so it should go here.
500 * fports.h (scm_stdio_to_port): Adjust prototype.
501 (scm_standard_stream_to_port, scm_freopen): New protoypes.
502 * ioext.h (scm_freopen): Prototype removed.
504 * filesys.c (set_element, get_element): This can work on both pipe
505 and file ports, so use SCM_FPORTP to typecheck, instead of testing
508 * scmconfig.h.in: Regenerated.
510 Change the definition of the functions in scm_ptobfuns so that
511 they get passed the port object, not the port's stream.
512 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
513 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
514 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
515 Pass the port itself to the scm_ptobs function.
516 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
517 scm_generic_fgets): Same.
518 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
519 getc_void_port, fgets_void_port, close_void_port): Just change the
520 argument names; these functions don't really do anything.
521 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
522 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
523 port as an argument, and use SCM_STREAM to get the stdio FILE *.
524 Also, use prototyped definitions, and get rid of the extra
526 (scm_fptob, scm_pipob): We don't need casts here any more.
527 * strports.c (prinstpt): Use prototype declarations.
528 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
529 and use SCM_STREAM to get the string info. Also, use prototyped
530 definitions, and get rid of the extra declarations.
531 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
534 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
535 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
537 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
538 scm_fgets, for consistency.
539 (scm_fptop, scm_pipob): References updated.
541 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
543 Include the source location in error messages for scripts.
544 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
545 stack is still there when we catch the error.
546 * throw.c (handler_message): If we are handling an error with a
547 message, then put together the proper arguments and call
548 scm_display_error, instead of scm_display_error_message. That
549 displays source location, if it can find it.
551 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
553 * gc.c (scm_unprotect_object): Change this so that calls to
554 scm_protect_object and scm_unprotect_object nest properly.
555 (scm_protect_object): Doc fixes.
557 * strings.c (scm_string_set_x): Require the argument to be a
558 writable string, not a substring or a symbol.
559 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
560 (Thanks to John Redford and Charbel Jacquin.)
562 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
564 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
566 * eval.c (safe_setjmp): Remove this misunderstanding.
567 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
570 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
572 * libguile.h: Mark these as C declarations, for compilation by C++
575 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
576 __cplusplus clause. I seriously doubt this ever worked the way
577 the author seems to have intended.
579 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
581 Utterly needless cleanups to hopelessly messy code.
582 * ports.c: Doc fixes.
583 (scm_fflush): Moved to ...
584 * genio.c (scm_fflush): ... here, amongst all the other port
585 method invocation functions.
586 * genio.h, ports.h: The prototype moves too.
588 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
590 * backtrace.c (display_error_body): The current frame does not
591 always have a parent frame; consider a function called directly
592 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
595 * alloca.c (alloca): Undo yesterday's changes, and simply call
596 malloc directly for storage, and abort if we don't get what we
597 want. The situation is much simpler --- just call malloc. Emacs
598 has bizarre/evil requirements (signal handlers might malloc unless
599 you set this global flag, so you have to set the flag around all
600 calls to malloc) which we are certainly not going to conform to,
601 so we can do the simple and obvious thing.
603 * coop.c (coop_condition_variable_wait): Make this function
604 static. It's only useful internally --- you should never just
605 wait on a condition variable.
606 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
608 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
610 * unif.c (scm_array_set_x): Accept any kind of number as an
611 element for a uniform vector of doubles. This is more consistent
612 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
614 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
615 works; I can't conveniently test it myself. (Thanks to Dvid
616 Tillman for the bug report.)
620 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
621 from here, not from scm_compile_shell_switches (which is a pretty
622 dumb place to do it).
623 (scm_load_startup_files): New function.
624 (scm_ice_9_already_loaded): Variable moved to here from script.c.
625 * script.c (scm_compile_shell_switches): Don't load the startup
627 (scm_ice_9_already_loaded): Variable moved.
628 * init.c (scm_load_startup_files): Prototype for new function.
629 * gh_init.c (gh_enter): Doc fix.
631 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
633 Some anti-warning changes from Greg Harvey.
634 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
635 warnings when it doesn't understand our NORETURN declarations in
637 * posix.c (scm_mknod): Similar.
639 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
641 * posix.c (scm_getpwuid): If we can't find an entry, return our
642 own message, instead of using scm_syserror --- the getpwMUMBLE
643 functions don't set `errno' to anything interesting.
645 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
647 Get rid of warnings from the cooperative threading system.
648 * threads.h (scm_single_thread_p, scm_yield,
649 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
650 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
651 scm_wait_condition_variable, scm_signal_condition_variable): Add
652 prototypes for these Scheme-visible functions.
653 * coop-defs.h (coop_next_runnable_thread,
654 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
655 Prototypes for these here, even though they're from iselect.c.
656 (coop_condition_variable_wait, coop_join): Add prototypes.
657 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
658 scm_threads_free_condvar): Make these smob functions static.
659 * coop-threads.h (coop_init): Give this a real prototype.
660 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
661 (coop_next_runnable_thread): No need to provide prototype; it's in
664 * scmconfig.h.in: .detarenegeR
666 * iselect.c, threads.c: Doc fixes.
668 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
670 * Makefile.in: Regenerated with a patched automake, to get
671 dependency generation right when using EGCS.
673 * inet_aton.c (inet_aton): Add prototype, to remove compiler
674 warning. (Thanks to Robert Pluim.)
676 * inet_aton.c (inet_aton): Reassure the compiler that the
677 arguments to the <ctype.h> macros are all unsigned characters, not
680 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
682 Getting rid of more warnings...
683 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
684 today's change to ../configure.in.
685 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
686 * scmconfig.h.in: Regenertaded.de.,.__
687 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
688 (scm_localtime, scm_mktime): Use a const char * to manipulate the
691 * readline.c: Doc fix.
692 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
693 * readline.h (scm_filename_completion_function): Add prototype.
694 (scm_init_readline): Make this into a prototype.
696 * readline.c (scm_filename_completion_function): Use SCM_PROC to
697 declare this, instead of calling scm_make_subr manually.
699 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
701 * readline.h (scm_init_readline): Add prototype for this.
702 (scm_init_readline): Make this a real prototype.
704 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
706 Warning fixes from Maciej Stachowiak:
707 * backtrace.h (scm_display_application, scm_backtrace): Add
709 * debug.c (scm_m_start_stack): Make this function static.
710 * fluids.h (scm_fluid_p): Add prototype.
711 * procprop.c (scm_i_procedure_arity): Make this function static.
712 * regex-posix.c (scm_regexp_error_msg): Make this function static.
713 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
714 * root.h (scm_dynamic_root): Add external prototype.
715 * scmsigs.h (scm_usleep): Add external prototype.
716 * script.h (scm_init_script): Use prototype, not K&R decl.
717 * stacks.h (scm_stack_id): Add external prototype.
718 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
720 1998-09-30 Mark Galassi <rosalia@cygnus.com>
722 * gh.h: took out the definitions of vset and vref, since they are
723 replaced by the proper vector routines that correspond to the R4RS
726 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
728 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
729 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
730 third argument, a C expression that should result in a SCM value,
731 which is used to initialize the variable. Reimplemented
732 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
735 * version.h (scm_libguile_config_stamp): Add prototype.
736 (From Maciej Stachowiak.)
738 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
740 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
741 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
743 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
745 * print.c (scm_iprin1): Rather than having one i, and using it in
746 several places, declare a fresh i local to each block where it is
747 used, and give it a signedness appropriate to its use in each case.
750 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
753 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
754 signed/unsigned clashes.
756 * posix.h (scm_tmpnam): Added prototype.
758 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
759 scm_make_subclass_object): Add external prototypes.
761 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
762 comparison is okay here.
764 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
766 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
767 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
769 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
772 * load.c (swap_port): Make this function static.
774 * load.c (scm_search_path): Make max_path_len and max_ext_len
775 unsigned, since they're compared against string sizes.
777 * load.c (init_build_info): Make i unsigned.
779 * ioext.h (scm_read_line): Add prototype.
781 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
782 scm_hash_fn_remove_x): Make hash bucket index local variable k
783 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
784 accurately as possible.
786 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
787 comparisons, and range checking to make sure those casts are
790 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
791 signed/unsigned comparisons.
793 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
794 avoid signed/unsigned comparisons.
795 * smob.h (scm_numsmob): Change extern declaration to match.
797 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
798 avoid signed/unsigned comparisons.
799 * ports.h (scm_numptob): Change extern declaration to match.
800 (scm_current_load_port, scm_set_port_line_x,
801 scm_set_port_column_x): New prototypes.
803 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
804 test code, and it causes warnings.
806 * gh.h (gh_int2scmb, gh_uniform_vector_length,
807 gh_uniform_vector_ref): Added prototypes.
809 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
810 debugging support unconditionally. That's backtrace.c, stack.c,
811 debug.c, and srcprop.c.
812 (EXTRA_libguile_la_SOURCES): Omit those from here.
813 * Makefile.in: Regenerated.
815 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
817 * options.c (scm_options): Bugfix: Allow empty list of options!
819 * debug.c, debug.h (scm_single_step): Removed.
820 (scm_with_traps): New procedure. This procedure could easily be
821 written in Scheme but needs to be highly optimized.
823 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
825 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
826 Check SCM_TRAPS_P before trapping.
828 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
830 Changes to avoid signed/unsigned comparison warnings.
831 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
832 (scm_gc_sweep): Make n and j local to the blocks they're used in,
833 so they can have appropriate types for each application. Make i
834 signed. Use initializers in some spots. I'll probably pay for
836 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
837 (scm_must_realloc): Make nm unsigned.
838 (init_heap_seg): Make new_seg_index and n_new_objects signed.
839 (scm_init_storage): Use prototype-style definition, and make the
841 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
842 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
844 * filesys.c (scm_readlink): Make local vars rv and size ints, to
845 avoid signed/unsigned comparison warnings, and because the return
846 value of readlink may be -1. Don't bother casting the third
847 argument to readlink.
849 * filesys.c (scm_dirname, scm_basename): Move these to their own
850 page, at the end of the file.
851 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
853 * eval.h (scm_eval_options_interface): Add external prototype for this.
854 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
856 * eval.c (scm_lookupcar1): Make this static.
858 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
859 Make these prototype declarations, not K&R-style.
861 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
862 unsigned comparison warning.
864 * appinit.c: File removed. It had a single function in it, empty,
865 whose reason for existence is explained in no documentation or
866 comment. I think it's there as a default for some Tcl-style
867 initialization, but Tcl abandoned that approach a while ago.
868 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
869 (BUILT_SOURCES): Remove appinit.x.
870 * Makefile.in: Regenerated.
872 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
874 * Makefile.in: Regenerated using the last public version of
875 automake, not the hacked Cygnus version.
877 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
879 Remove Totoro kludge.
880 * Makefile.in, scmconfig.h.in: Regenerated.
881 * init.c, readline.c: Don't check if TOTORO is #defined.
883 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
885 * Makefile.am: Adjust for new thread configuration system.
886 (INCLUDES): Include the value of THREAD_CPPFLAGS.
887 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
889 (THREAD_LIBS): Definition deleted; automake will generate such
890 things automatically.
891 * Makefile.in: Regenerated.
893 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
895 Simplify smob and port marking; set the mark bit in the generic
896 marking code, and make marker routines only responsible for
897 turning up outgoing pointers.
898 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
899 before calling the marking function. Don't call the marking
900 function if it's zero.
901 * markers.c (scm_mark0): Just return #f. This function isn't
902 necessary at all now, but it's harmless to call it. We'll leave
903 it in so other folks' code doesn't croak at link time.
904 (scm_markcdr): Don't call SCM_SETGC8MARK.
905 * async.c (mark_async): Don't call SCM_SETGC8MARK.
906 * dynl.c (mark_dynl_obj): Same.
907 * root.c (mark_root): Same.
908 * srcprop.c (marksrcprops): Same.
909 * unif.c (markra): Same.
910 * variable.c (scm_markvar): Same.
911 * ports.c (scm_markstream): Same.
912 (void_port_ptob): Specify zero for our marking function.
913 * debug.c (debugobjsmob): Same.
914 * dynwind.c (guardsmob): Same.
915 * filesys.c (dir_smob): Same.
916 * fluids.c (fluid_smob): Same.
917 * fports.c (scm_fptob, scm_pipob): Same.
918 * mallocs.c (mallocsmob): Same.
919 * regex-posix.c (regex_t_smob): Same.
920 * smob.c (freecell, flob, bigob): Same.
921 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
922 * throw.c (jbsmob, lazy_catch_funs): Same.
924 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
926 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
927 scm_copy_tree on code in order not to let memoized code to leak
928 out. Thus, scm_copy_tree needs to copy vectors as well since
929 quasiquote can introduce evaluated code also inside vector
932 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
934 * eval.c (scm_copy_tree): Removed ability to copy vectors.
936 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
937 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
940 * unif.c: Say that ivect and uvect are of type signed and unsigned
941 long instead of int in commentary so that it correctly describes
944 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
946 * stime.c: Removed declaration of strptime. (It should be
947 declared by the system headers. If it turns out that some systems
948 don't, we'll handle that then.) (Thanks to Greg Troxel.)
950 * stime.h: Renamed TIMEH --> STIMEH
952 * backtrace.c (scm_display_error, scm_display_backtrace): In order
953 to increase portability, don't use structure assignment.
954 (Thanks to Nicolas Neuss.)
956 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
958 (finalize_fd_sets): Added empty statement after last case label.
959 (Thanks to Nicolas Neuss.)
961 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
964 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
966 * init.c, readline.c: OK, I won't have these readline.x bug
967 reports anymore. We've had them since April. The current reason
968 is a completely unintelligible failure of totoro.red-bean.com to
969 do the test for rl_getc_function in libreadline correctly. This
970 kludge overrides the test if we're on totoro so that the snapshot
971 generation process can work.
973 * readline.c: Define a strdup replacement if not existent on system.
975 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
977 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
978 This change makes scm_make_vector R5RS compatible. We cannot keep
979 the third argument since people want to be able to deduce the form
980 of the C function call only by looking at R5RS. (At the same time
981 we have removed some unnecessary complexity!)
983 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
984 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
985 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
986 argument in call to scm_make_vector.
988 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
990 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
991 This macro is useful in applications.
993 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
995 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
996 (scm_parse_path, scm_search_path): New Scheme level procedures.
998 * load.h (scm_internal_parse_path, scm_parse_path,
999 scm_search_path): Declared.
1001 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1003 * filesys.c (dirname, basename): New procedures.
1005 * init.c (scm_boot_guile_1): Removed condition around
1008 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
1009 new data type (guards) for representation of C level guards and
1010 data on the wind chain.
1011 (scm_internal_dynamic_wind): New function.
1013 * dynwind.h: Declare scm_internal_dynamic_wind.
1015 * root.h (scm_root_state): Added scm_cur_loadp.
1017 * root.c (mark_root): Added comment about cur_loadp.
1019 * load.c: #include "dynwind.h";
1020 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1023 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1025 * ports.c (current-load-port): New procedure.
1027 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1029 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1030 not a tty, return #f.
1032 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1033 to Julian Satchell and Roland Kaufmann.)
1035 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1036 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1038 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1040 * debug.h, debug.c (scm_start_stack): New function. Implements
1041 the guts of old scm_m_start_stack.
1043 * debug.c (scm_m_start_stack): Use scm_start_stack.
1045 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1046 start_stack and restart_stack. (These have static scope.)
1048 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1050 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1051 readline functions to come in release 2.3. (Thanks to Chet
1053 (handle_errors): Use the above functions.
1055 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1057 * readline.c: Improvements for readline support: Handle errors
1058 better; Implement before-read-hook.
1060 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1062 * init.c (scm_boot_guile_1), readline.c: Test for
1063 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1064 assure that we have version >= 2.1.)
1066 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1068 * readline.c (scm_readline): Defer interrupts while we're calling
1071 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1072 away the string to add_history.
1073 (completion_function): Do completion for readline. (Thanks to
1075 (scm_filename_completion_function): New procedure: Filename
1077 (current_input_getc): New function. Use this one instead of
1078 standard getc from readline.
1080 * throw.c, throw.h (scm_handle_by_throw): New function: This
1081 handler throws errors to next handler on the dynwind chain.
1083 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1085 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1088 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1090 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1092 (scm_procedure_properties): Modified to return arity together with
1094 (scm_procedure_property): Added the read-only property `arity'.
1095 (scm_set_procedure_property_x): It is an error to set the `arity'
1098 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1099 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1101 * procprop.h (scm_sym_arity): New symbol.
1103 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1104 to set the dispatch procedure of an operator or entity object.
1106 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1107 Made procedure slots read-only.
1109 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1110 scm_tcs_cons_gloc case in zero args switch; Fixed args
1111 construction for operators in scm_tcs_cons_gloc case in two args
1114 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1116 * fluids.c: Removed use of assert.h (in order to avoid
1119 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1121 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1123 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1124 change makes the evaluator safer at the cost of evaluation speed.
1125 It handles the case when the user has added a non-immediate
1126 improper end of the application form, e.g., `(+ 0 . x)'.
1127 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1128 minimize the extra cost as much as possible. The new code is
1129 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1130 problem with structs planted directly in the code (e.g. by a
1131 macro). This no longer causes segmentation fault. (Thanks to
1134 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1135 arg `proc' in order to be able to throw errors; New argument
1138 * Removed extra #include "debug.h"
1140 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1142 * scmsigs.c: Declare usleep as returning void on some systems.
1143 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1146 * coop.c (usleep): Return void on some systems.
1148 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1150 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1152 * coop.c: Changed return type of usleep to int.
1154 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1155 isn't found in the OS.
1157 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1158 isn't enabled. (Thought that I had made this change ages ago...)
1160 * iselect.c: Declare bzero if not defined by OS.
1162 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1164 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1165 condition. (Thanks to John Tobey.)
1167 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1168 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1171 * __scm.h: Start the long-term project of moving to POSIX threads.
1172 Phase 1: Classification of all critical sections.
1173 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1174 for A sections. (See comments in __scm.h for details.)
1176 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1177 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1179 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1181 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1182 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1183 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1184 dependencies on $(srcdir)/Makefile.in
1185 $(top_builddir)/config.status in order to avoid circularity.
1187 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1188 from argc if argc was 0 initially.
1190 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1191 in generation of libpath.h.
1193 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1195 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1196 libguile from 2 to 3.
1198 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1200 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1202 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1204 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1205 scm_set_port_column_x, scm_port_filename,
1206 scm_set_port_filename_x): Removed optional arguments. Added
1207 proper argument checking.
1209 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1210 stack size in machine words.
1212 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1213 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1214 to Ole Myren Röhne.)
1216 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1218 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1219 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1221 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1224 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1225 procedure apply: Copy argument lists before pushing them unto the
1226 environment so that the environment won't get mutated due to
1227 manipulation of procedure arguments. This should perhaps be
1228 regarded as a temporary solution until someone finds a more
1229 efficient one. (Thanks to Maciej Stachowiak.)
1231 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1233 * script.c (scm_compile_shell_switches): Use "guile" as default
1234 zero arg if argc is NULL.
1236 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1238 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1239 is zero. (Thanks to Dirk Herrmann.)
1241 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1243 * ports.c (scm_add_to_port_table): First line is now line 0
1244 (was 1). (Interface changed according to suggestion by Per
1247 * backtrace.c (display_header): Add 1 to line and column numbers
1248 when presenting them to the user.
1250 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1251 from debug.c --> eval.c
1253 * eval.h, eval.c (scm_eval_options_interface): New options
1255 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1256 i.e. stacks for new threads.
1258 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1260 * eval.c (unsafe_setjmp): Removed with #if 0.
1262 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1265 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1266 to avoid compiler warnings.
1268 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1270 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1272 * throw.c (handler_message): Print message on current error port
1273 instead of default error port. (Thanks to Maciej Stachowiak.)
1275 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1277 * ports.c (scm_add_to_port_table): allocate in units of
1278 struct scm_port_table *, not struct scm_port_table.
1279 * posix.c (scm_close_pipe): remove the port from the port table
1281 Thanks to Rob Engle for both fixes.
1283 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1285 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1286 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1288 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1290 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1292 * backtrace.c (display_error_body, display_backtrace_body),
1293 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1294 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1295 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1296 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1299 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1300 don't receive the jmpbuf arg anylonger.
1301 (scm_catch): Don't accept a #f tag.
1302 (scm_throw): Check that key is a symbol.
1303 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1305 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1307 * async.c (async_pending): Removed declaration.
1309 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1311 * dynwind.c (scm_wind_chain): New debug function.
1313 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1314 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1315 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1316 extra layer of functions around the body and handler of a thread.
1317 This extra layer makes sure that the handler is called in the
1318 dynamic context of the surround (= empty dynwind list), but under
1319 the *dynamic root* of the body. We can not use the dynamic root
1320 of the surround since that root belongs to another thread => stack
1321 is not handled correctly. It may seem ugly to use this extra
1322 layer, but the extra cost in terms of execution time is really
1323 negligible compared to the total amount of time required to create
1324 a thread, and it would reduce maintainability to duplicate the
1325 crucial and complicated steps performed by cwdr.
1327 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1328 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1329 get re-enabled. The important effect of this is that interrupts
1330 are blocked during thread switching so that thread data structures
1331 don't risk getting messed up by an unfortunate signal.
1332 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1333 seems to do more aggressive optimization which actually move
1334 instructions around in these macros in a fatal way. Therefore:
1335 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1336 just superstitious...)
1337 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1338 This macro should be used instead of SCM_ASYNC_TICK since the
1339 latter doesn't do context switches any more.
1341 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1342 instead of SCM_ASYNC_TICK.
1344 * coop.c, iselect.c: Since thread switches are now performed with
1345 interrupts masked, we can't use the old mechanism of delivering
1346 signals immediately when they arrive. Signals must instead be
1347 delivered when the asyncs run *after* the end of the critical
1348 section in scm_internal_select. But this also means after context
1349 switch so that the signal will be delivered to a different thread.
1350 To avoid this, I have changed the protocol of
1351 coop_wait_for_runnable_thread and friends so that they are allowed
1352 to return the original thread. So, if a signal arrives during
1353 scm_internal_select, we won't any longer be forced do a context
1354 switch, but can remain in the same thread and deliver the signal
1357 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1358 scm_asyncs_pending and made it global.
1360 * iselect.c: Small fixes.
1362 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1363 coop_condition_variable_init, coop_condition_variable_wait,
1364 coop_condition_variable_signal): Changed return type from `void'
1365 to `int'. This is to adhere closer to the pthreads interface.
1366 This, in turn, is part of an attempt to provide C versions of the
1367 mutex and condition variable primitives which can be part of a
1368 frontend to COOP or pthreads.
1370 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1371 coop_condition_variable_destroy): New functions.
1373 * coop-threads.c (scm_wait_condition_variable): Use
1374 coop_condition_variable_wait_mutex.
1376 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1377 Definitions moved to coop-defs.h.
1379 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1380 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1381 scm_cond_destroy): New C interface to mutecis and cond vars.
1383 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1385 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1387 * iselect.c: Now several threads can wait on the same file
1388 descriptor. The behaviour is compatible with OS select: All
1389 threads waiting for the fd return with the same status.
1391 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1393 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1394 Can spawn a thread from application C code.
1396 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1398 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1399 gh_doubles2scm): New functions.
1401 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1403 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1404 commented-out version of gh_eval_str()
1406 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1408 * socket.c (scm_bind): free soka after use.
1410 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1412 * stime.c (tzvar): new variable.
1413 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1414 avoid memory leaks when allocating.
1416 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1418 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1421 * gc.c, tags.h: Doc fixes.
1423 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1425 * eval.c (macro-eval!): Removed. This function was a design bug.
1426 It allowed memoized code to leak out to the scheme level. Most
1427 things that you could do with `macro-eval!' can be done with
1430 1997-12-20 Tim Pierce <twp@skepsis.com>
1432 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1433 scm_fgets now depends on ftell(3) to know how many bytes were
1436 1997-12-15 Tim Pierce <twp@skepsis.com>
1438 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1439 dealing with strings.
1441 1997-12-13 Tim Pierce <twp@skepsis.com>
1443 Make %read-line more suitable for implementing read-line efficiently.
1444 * ioext.c (scm_read_line): Strip the terminating newline from a
1445 string, and return a cons of the string and its terminator.
1447 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1448 of the string that is read is stored in this memory location.
1449 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1450 * genio.c, genio.h (scm_do_read_line): Update caller.
1451 * ports.h (scm_ptobfuns): Update typedef.
1452 * fports.c (scm_fptob, scm_pipob): Update struct.
1454 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1456 * filesys.c (set_element): Return file descriptor.
1457 (fill_select_type): Return the highest file descriptor.
1458 (scm_select): Tell select about the highest file descriptor. On
1459 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1460 Therefore the extra overhead for calculating the maximum fd seems
1461 to be more than compensated. Is this correct? In any case,
1462 scm_internal_select will be much faster with this info.
1463 (scm_select, fill_select_type, set_element): Don't accept any kind
1464 of object in the file descriptor list or vector.
1466 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1468 * iselect.c (finalize_fd_sets): Bugfix.
1470 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1472 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1473 when using scm_internal_select (since we might switch to another
1476 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1478 * simpos.c (scm_system): always define: use sysmissing if not
1479 available. Check for HAVE_SYSTEM instead of _Windows (does
1480 Windows lack system or does it have an unusable one?).
1481 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1482 Let the argument be optional: if not supplied, call system(NULL).
1484 * ports.c (scm_close_port): relax the type check from OPPORTP to
1485 PORTP; closing a closed port is allowed.
1487 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1489 * fports.c (scm_fgets): Return if the last char in a chunk is
1490 newline. When fgets returns a string whose length is `size-1', it
1491 is ambiguous whether a whole line was retrieved, so we must check
1492 explicitly whether a line terminator is present.
1494 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1496 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1497 before taking the CDR. (Thanks to Harald Meland.)
1499 * filesys.c (scm_stat): Slightly optimized.
1501 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1503 * ports.c (scm_close_port): Make sure the port is open before
1506 * guile-snarf.in: Pass args through to gcc in a way that preserves
1507 whitespace boundaries. (Thanks to Greg Badros.)
1509 1997-12-02 Tim Pierce <twp@skepsis.com>
1511 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1512 statement. (Thanks to Doug Evans for pointing this out.)
1514 1997-12-01 Tim Pierce <twp@skepsis.com>
1516 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1518 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1520 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1521 errno macro expansion of this field name. (errno is a C
1522 preprocessor macro on some systems.)
1524 1997-11-29 Tim Pierce <twp@skepsis.com>
1526 * iselect.c: Doc fix.
1528 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1530 * init.c (scm_start_stack): Removed initialization of
1531 scm_the_last_stack_var.

1539 * root.h (scm_root_state): Removed the_last_stack_var.
1541 * throw.c: Added #include "fluids.h"

1544 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1545 --> the_last_stack_fluid.
1547 * backtrace.c: Added #include "fluids.h"

1561 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1563 * iselect.c (coop_next_runnable_thread,

1573 * coop.c (coop_qinit): Initialize fields used by
1574 scm_internal_select.
1575 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1576 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1577 replacement in iselect.c.
1578 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1579 coop_join): If GUILE_ISELECT enabled, use
1580 coop_wait_for_runnable_thread instead of
1581 coop_next_runnable_thread.
1582 (usleep, sleep): New replacements for system functions if
1583 GUILE_ISELECT is enabled.
1585 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1587 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1589 * filesys.c: Added #include "iselect.h". Moved FD-macros to

1591 scm_internal_select. (See NEWS.)
1593 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1595 * init.c: Call scm_init_iselect.

1600 1997-11-27 Tim Pierce <twp@skepsis.com>
1602 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1603 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1604 and scm_must_free, since ultimately the string returned will be copied
1605 by scm_makfrom0str anyway. Also, read any characters that may have
1606 been pushed onto the port with scm_ungetc.
1607 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1608 * ioext.c (scm_read_line): Free string after Guilifying it.

1620 gh_repl (argc, argv).
1622 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1624 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1625 and to invoke scm_shell().
1626 (gh_launch_pad): took out the loading of boot-9.scm from here,
1627 since it is probably best to let the user control that. In fact,
1628 gh_repl() now invokes scm_shell() which does that.
1630 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1632 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1654 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1655 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1657 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1659 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1660 configure.in was changed).
1662 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1664 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1665 * Makefile.in: Regenerated.
1667 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1669 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1670 OPORT is an `open' port, not an output port.
1672 * filesys.c (scm_close, set_element, get_element, scm_chown,
1673 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1678 scm_set_port_filename_x, scm_port_mode,
1679 scm_close_all_ports_except, scm_set_current_output_port,
1680 scm_set_current_error_port): Likewise
1681 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1682 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1684 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1685 * backtrace.c (display_backtrace_body): Likewise
1686 * fports (scm_setvbuf): Likewise
1687 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1694 Minor problems with substring-related tag changes.
1695 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1696 exactly what we want to leave in to detect substrings.
1697 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1698 * tags.h: Fix diagrams and comments describing the S tag bit;
1699 remove vestigial remarks about the D tag bit.

1701 * strings.c: Formatting tweaks.
1703 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1704 variable first; then SCHEME_LOAD_PATH, with a warning message.
1705 (scm_parse_path): New function.
1706 * script.c: Doc fixes.
1708 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1710 Readline support, from Daniel Risacher.
1711 * readline.c, readline.h: New files.
1712 * init.c: #include "readline.h".
1713 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1714 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1715 * Makefile.in: Regenerated.
1716 * scmconfig.h.in: Regenerated, after change to ../configure.
1718 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1720 * gh.h: gh_vector_set -> gh_vector_set_x
1722 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1724 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1725 with the ! -> _x mapping when going from Scheme to C.
1727 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1729 * gh.h (gh_reverse):
1737 (gh_assoc): added these gh_ functions implemented as macros.

1740 (gh_string_equal_p): added these two missing predicates.
1742 * gh_list.c (gh_append):
1747 (gh_set_cdr_x): added these routines as I go through and try to
1748 complete the picture R4RS functions that should be mirrored in the
1751 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1753 * tags.h (scm_tc7_substring): Changed the comment and code to
1754 conform with the changes below. Folks! We have suddenly two new
1755 free tc7 codes!!! Jummy, jummy!
1757 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1759 * Makefile.in: Rebuilt.

1793 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1794 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1795 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1815 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1817 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1819 * gh_test_c.c (c_vector_test): some improvements on the vector
1822 * gh.h (gh_vector): this used to exist but do the wrong thing.
1823 Now it (almost) does the right thing, though it takes a list
1824 instead of the individual arguments. I need to see how it could
1826 (gh_list_to_vector): added this function as a macro. Corresponds
1827 to Scheme's (list->vector ...).
1828 (gh_vector_to_list): added this function as a macro. Corresponds
1829 to Scheme's (vector->list ...).
1831 * gh_data.c (gh_vector_ref): renamed from gh_vref to

1833 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1834 resembles the Scheme routines more.
1835 (gh_make_vector): this used to be (stupidly) called gh_vector().
1836 This is the right name, since it does the same thing as the Scheme
1837 (make-vector ...) procedure.
1839 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1841 * ports.h: #include "libguile/print.h"

1856 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1858 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1859 macros should by convention not test for NIMPness.)
1860 (SCM_COERCE_OPORT): Adjust indentation.
1862 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1863 SCM_NIMP test before SCM_PRINT_STATE_P.

1870 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1872 * struct.c (scm_print_struct): Use new printer slot; Default
1873 printing: Also output hex code of vtable so that type identity
1874 will be indicated as well.
1875 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1876 Removed struct_printer_var; Removed struct-vtable-offset;
1877 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1878 vtable-offset-user): New constants.
1880 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1883 the type represented by this vtable.
1885 * print.c (scm_iprin1): Don't print arguments of macro
1886 transformers. (They are always: exp env.); Bugfix: Unmemoize
1887 transformer source with correct environment.
1889 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1891 Streamlining of call-with-dynamic-root:

1895 (cwdr_outer_body): Removed.
1896 (cwdr_handler): New function.
1897 (scm_internal_cwdr): New function to perform the function of cwdr
1898 but take args that are more useful to C code. Also, the handler
1899 is now invoked *outside* of the new dynamic root, like the docs
1900 say. We no longer have to catch absolutely all errors, the caller
1901 is responsible for using a handler that does not throw, if he
1903 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1904 * root.h (scm_internal_cwdr): New prototype.
1906 Even more but risky streamlining:
1908 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1909 allocation of the jumpbuf of a root continuation. The changes
1910 below are controlled by it. They are now deactivated.
1911 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1912 the JMPBUF of the scm_rootcont to NULL before returning.
1914 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1915 when they are non-NULL.
1916 (scm_gc_mark): Likewise, mark only when non-NULL.
1918 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1919 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1921 * gc.c (scm_done_malloc): New function.
1922 gc.h (scm_done_malloc): New prototype.
1924 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1931 a certain value is acceptable as a port argument.
1932 (scm_print_state_vtable): New variable.
1933 (scm_free_print_state): Set `revealed' field to false.
1934 (scm_iprin1): Call user supplied closure printer with
1935 scm_printer_apply. Print in the traditional way when there isn't
1936 one or when it returns #f.
1937 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1938 Accept a port/print-state pair in addition to just a port.
1939 (scm_prin1): Don't return the print_state to the pool when it has
1941 (scm_printer_apply): Set `revealed' field of print_state to true.
1942 (scm_init_print): Set scm_print_state_vtable.
1943 (print_state_fluid, print_state_fluid_num): Removed.
1945 * throw.h (scm_handle_by_proc_catching_all): New prototype
1946 throw.c (scm_handle_by_proc_catching_all): New function
1948 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1950 * Makefile.in: Regenerated with automake 1.2c.
1952 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1954 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1955 was looping endlessly.
1957 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1959 * strports.c (scm_eval_string): Don't close the port.
1961 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1962 former returns a nice normal integer. (Thanks to Daniel
1965 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1967 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1968 makefile variable as a build parameter called LIBS. The
1969 build-guile program will use this, for the time being.
1970 * Makefile.in: Regenerated.
1972 Thanks to Shiro Kawai:
1973 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1974 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1977 * Makefile.in: Regenerated with automake 1.2a.
1979 * script.c (scm_compile_shell_switches): If we hit the -c or --
1980 arguments, don't set the car of (command-line) to scm_usage_name,
1981 the prettified name of the guile executable; give it the full
1982 path, the way shells usually handle $0.
1984 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1986 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1987 Scheme-level name `array-map' and renamed `serial-array-map' to
1988 `serial-array-map!'.
1990 * backtrace.c: Introduced exception handlers which now enclose
1991 `display-error' and `display-backtrace' so that error reporting
1992 won't get into infinite loops if an error occurs during displaying
1993 of the error. This can very easily happen with user supplied
1994 print call-back routines.
1996 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1998 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1999 the names `serial-array-map' and `array-map' should be removed.)
2001 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2003 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2004 Added #include "objects.h"
2006 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2007 Add #include "feature.h".
2009 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2010 (modinclude_HEADERS): Added objects.h.
2012 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2013 This test is needed at many places in the code and should be
2014 abstracted. (Motivated by the need of this test in libguiletk.)
2016 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2017 (scm_eval_string), load.c (scm_primitive_load,
2018 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2019 Use SCM_EOF_OBJECT_P.
2021 * eval.c (scm_init_eval): Add feature `delay'.
2023 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2025 * scmhob.h: Removed.
2027 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2029 * list.h (SCM_LISTn): New macros. Make list creation in C code
2030 prettier. The idea comes from STk.
2032 * sequences.h, sequences.c, append.h, append.c: Removed. These
2033 files implemented non-R4RS operations which would encourage
2034 non-portable programming style and less easy-to-read code.
2036 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2039 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2040 sequences.h, #include append.h.
2042 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2045 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2047 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2049 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2051 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2053 * eval.c: Added #include "objects.h"
2055 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2058 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2059 adjacent smob numbers.
2061 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2063 * procprop.h: Added declaration of scm_i_inner_name.
2065 * gsubr.c: New global symbol scm_i_inner_name.
2067 * debug.c (scm_procedure_name): Try procedure property
2068 `inner-name' if `name' fails.
2070 * print.c (scm_iprin1): Use scm_macro_name.
2072 * eval.c (scm_m_define): Give names to macros as well; Only the
2073 first top-level definition gives a procedure/macro a name.
2074 Otherwise confusing names can turn up in backtraces.
2075 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2076 `name'; Give names to macros as well.
2078 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2079 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2082 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2084 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2086 (prinmacro): Removed. The code has been moved/merged into print.c
2087 in order to decrease code redundancy. We want macros to print in
2088 a way equivalent to procedures, and it would be silly to duplicate
2089 the required code. (We don't want to maintain two places.)
2090 (macrosmob): Print field is now a NULL pointer.
2092 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2093 scm_macro_transformer): New prototypes.
2094 (scm_tc16_macro): Declared.
2096 * print.c (scm_iprin1): Added code for printing of macros. Macros
2097 are now printed in a way equivalent to procedures.
2099 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2101 * procs.h (scm_closure_p): Added declaration.
2103 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2105 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2106 Shouldn't pass "heap" as the subr name.
2108 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2110 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2111 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2112 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2113 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2114 SCM_BOOL_T. Any non-false value is true.
2116 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2118 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2119 scm_gensym): Added prototypes.
2121 * symbols.c (scm_gensym): New function. This will speed up
2122 certain types of applications (such as macro systems) which
2123 generate lots of symbols.
2125 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2127 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2129 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2131 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2132 specifier, since (2) or (2 . 3) would cause SEGV.
2133 (scm_transpose_array): more argument checking fixes.
2135 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2137 * Makefile.in: Regenerated.
2139 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2141 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2143 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2145 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2147 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2149 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2150 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2153 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2154 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2155 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2156 scm_array_p, scm_array_rank, scm_array_dimensions,
2157 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2158 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2159 scm_array_prototype): Added case scm_tc7_wvect.
2161 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2163 * errno.h: prototype for scm_strerror.
2164 * error.c (scm_strerror): new procedure.
2166 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2168 * list.c (scm_list_append_x): Allow non-pair as last argument.
2169 This is consistent with the R4RS append and is probably the
2170 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2172 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2174 * stime.h: prototype for scm_times.
2175 * stime.c (scm_times): new procedure.
2176 * ioext.c (scm_fseek): if the first argument is a file descriptor
2178 (scm_ftell): if the first argument is a file descriptor call lseek
2180 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2181 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2183 (scm_chown): if the first argument is a port or file descriptor,
2185 (scm_truncate_file): new procedure.
2186 Add DEFER/ALLOW INTS to a few other procedures.
2187 (scm_fsync): new procedure.
2188 (scm_open_fdes): new procedure.
2189 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2191 (scm_fcntl): the first argument can now be a file descriptor. The
2192 third argument is now optional.
2194 * posix.c (scm_execl, scm_execlp): make the filename argument
2195 compulsory, since omitting it causes SEGV.
2196 (scm_sync): return unspecified instead of #f.
2197 (scm_execle): new procedure.
2198 (environ_list_to_c): new procedure.
2199 (scm_environ): use environ_list_to_c. disable interrupts.
2200 (scm_convert_exec_args): take pos and subr arguments and
2201 improve error checking.
2203 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2205 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2206 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2207 argument to SCM_ASSERT. Furthermore, the name of the function
2208 should be passed as first argument when signalling
2209 SCM_WNA. (Thanks to Thomas Morgan)
2211 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2212 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2213 dispatches on the number of actual args has a default case
2214 reporting an internal error. This is a vestige from a version
2215 that mallocated a SCM vector to hold the arguments. In the
2216 current version this check is too late: if it ever happens we will
2217 have already overstepped the bounds of the array.
2219 Also, the patch [...] adds a check for too many actual arguments."
2221 mdj: Removed check for "internal programming error".
2223 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2225 * gh_io.c (gh_write): New function.
2227 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2228 throw.c (scm_internal_stack_catch): New sibling to the other catch
2229 functions. Code moved from gh_eval.c.
2230 throw.h: Added header.
2231 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2232 scm_internal_stack_catch.
2234 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2236 * ioext.h: fix up prototypes.
2237 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2238 Scheme name is now dup->fdes.
2239 (scm_dup_to_fdes): make the second argument optional and
2240 fold in the functionality of scm_primitive_dup.
2241 (scm_primitive_dup): deleted.
2243 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2245 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2246 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2247 ultrix are defined. Use setvbuf instead of setbuf.
2248 (scm_setvbuf): new procedure.
2249 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2250 (scm_setfileno): moved from ioext.c.
2251 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2252 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
2254 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2256 * fluids.c (scm_fluid_p): New function.
2257 * fluids.h (scm_fluid_p): New prototype.

2261 * print.c (scm_iprin1): Enter printed structures into the print
2262 state as nested data while they are printed.
2263 (print_state_fluid, print_state_fluid_num): New variables.
2264 (scm_init_print): Initialize them.
2265 (scm_iprin): If print_state_fluid carries a print_state, use that
2266 instead of creating a new one.
2267 (scm_printer_apply, apply_stub, struct apply_data): New
2268 definitions to help with calling printer functions written in
2270 * print.h (scm_printer_apply): New prototype.
2272 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2273 user defined struct printer.
2275 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

2283 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2284 SCM_ASSERT: arg comes before pos.
2286 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2288 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2289 to a list of length zero correctly.
2291 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2293 Supply an `fgets' method for port objects to do fast line i/o.

2307 * ioext.h: removed scm_duplicate_port prototype.
2309 * ioext.c (scm_primitive_dup2): return the new file descriptor
2310 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2312 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2313 stream has been set.
2314 (scm_duplicate_port): deleted, there's now an implementation in
2316 (scm_primitive_dup2): do nothing if newfd == oldfd.
2318 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2320 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2324 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2326 * fluids.c (next_fluid_num): don't do
2327 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2329 * ports.h: prototypes too.
2330 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2332 * fports.h: prototype too.
2333 * fports.c (scm_evict_ports): moved from ioext.c.
2335 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2347 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2349 * fluids.c, fluid.h: New files.
2350 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".

2360 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2361 unique for the new root when it has a parent.
2363 * smob.h: Include "libguile/print.h" to make scm_print_state
2366 * dynl.c (free_dynl_obj): New function to free the dynamic object
2367 data. (dynl_smob): Use it.
2368 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2369 the dynamic object data below the linking of the object to avoid
2370 memory leak when the linking code throws an error. Now the code
2371 leaks a whole dynamically linked library when must_malloc throws,
2372 but that should be much less likely.
2374 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2376 Changes to compile under gnu-win32, from Marcus Daniels:
2377 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2378 (scm_localtime): Change SCM_EOF to SCM_EOL.
2379 (scm_mktime): Likewise.
2380 * socket.c: Don't include sys/un.h unless autoconf tells
2381 us Unix domain sockets are available.
2382 (scm_fill_sockaddr): Ignore Unix domain code.
2383 (scm_addr_vector): Likewise.
2384 (scm_init_addr_buffer): Likewise.

2391 was found during autoconf (in this case, getgroups).
2392 (scm_setpwent): For setpwent.
2393 (scm_setegid): For setegid.
2394 * net_db.c (scm_inet_netof): Don't include unless support
2395 function was found during autoconf (in this case, inet_netof).
2396 (scm_lnaof): For inet_lnaof.
2397 (scm_inet_makeaddr): For inet_makeaddr.

2409 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2410 scm_misc_error, not SCM_EOF.
2412 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2413 arguments for formatting the error message, not SCM_BOOL_F. I
2414 think this is left over from the (eq? '() #f) days.
2416 * read.c (recsexpr): Give this a dummy definition if
2417 DEBUG_EXTENSIONS isn't #defined.
2419 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2421 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2424 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

2431 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2432 alloca.lo will be included in @LIBLOBJS@. Something better than
2433 this should be possible.
2434 * Makefile.in: Regenerated.
2436 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2438 * simpos.h: prototype for scm_primitive_exit.
2439 * simpos.c (scm_primitive_exit): new procedure, terminates the
2440 process without unwinding the stack.
2442 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2444 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2445 argument and logior its components together, so the user doesn't
2446 have to do this explicitly. Also, if regexp/basic is supplied, then
2447 turn off REG_EXTENDED.
2448 (scm_init_regex_posix): New regexp/basic symbol.
2449 (REG_BASIC): #define this if it is not already present.
2451 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2453 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

2462 years in usage message.
2464 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2465 * Makefile.in: Regenerated.
2467 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2468 flag; I don't think we support it.
2469 (scm_make_regexp): Make sure the user doesn't pass the
2472 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2474 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2475 name them according to the SCSH convention: regexp/mumble.
2477 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2479 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2481 * Makefile.am (libpath.h): Include the values of all the standard
2482 Makefile directory variables. Print a message, but don't print
2484 (versiondat.h): Print a message, but don't print all the commands.
2485 * load.c: #include "alist.h".
2486 (init_build_info): New function.
2487 (scm_init_load): Call it.
2488 * Makefile.in: Regenerated.
2490 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2492 * root.c: Establish a reliable catch-all handler for the new root.
2493 After all the Scheme handler function might signal an error too,
2494 and we don't want to lose that.
2495 (cwdr_inner_body): Renamed from cwdr_body.
2496 (cwdr_outer_body): New function, to establish the user's handler,
2497 and pass control to cwdr_inner_body.
2498 (cwdr): Establish the reliable catch-all handler here, and pass
2499 control to cwdr_outer_body.
2500 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2501 the user's handler through to cwdr_outer_body.
2502 * throw.c (scm_handle_by_message): Move guts into....
2503 (handler_message): New static function.
2504 (scm_handle_by_message_noexit): New function.
2505 * throw.h (scm_handle_by_message_noexit): New prototype.
2507 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2508 across this. Only works on GCC. Otherwise, we hope for the best.
2509 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2510 the feeling that real thread systems will not need this...
2512 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2514 Try to detect when people are using one version of libguile and a
2515 different version of ice-9. People have been skewing things and
2516 sending in bug reports.
2517 * Makefile.am (versiondat.h): New file to generate.
2518 * version.c: #include "versiondat.h", to get version info.
2519 (scm_libguile_config_stamp): New function.
2520 * script.c: #include "version.h".
2521 (scm_compile_switches): Call scm_version to get version number.
2522 * scmconfig.h.in, Makefile.in: Regenerated.
2523 * Makefile.in: Regenerated.
2525 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2526 primitive definitions under their Scheme names.
2528 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2529 1:2. Helps avoid confusion between installed and uninstalled libs.
2531 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2534 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2535 backslash from definition; this should be used like: GDB_INTERFACE;
2537 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2539 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2540 new port unbuffered until its stream has been set.
2542 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2544 * ports.h: new prototype.
2545 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2547 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2549 Make things compile neatly under Sun's C compiler.
2550 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2551 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2552 unsigned, because that's what the ANSI function takes.
2553 * extchrs.h (xmbtowc): Corresponding change to prototype.
2554 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2556 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2557 argument plain char *.
2558 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2560 * tag.c (scm_tag): Remove unreachable statement.
2561 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2562 top of the word, it should be unsigned.
2564 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2565 is defined, to avoid warnings; it's only used in the
2566 conflict-checking code. Which might go away anyway.
2567 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2568 conditionals; put the label definition in an #if too, to stifle
2571 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2572 ChangeLog-threads in the distribution.
2573 * Makefile.in: Regenerated.
2575 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2577 * guile-snarf.in: Changed regexp to support CPPs that insert
2578 whitespace between lexical tokens (which munges the `%%%' snarf
2581 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2583 * load.c (scm_init_load_path): Append $(datadir)/guile to
2584 %load-path, so modules do not have to be installed in Guile's
2585 current version directory.
2587 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2589 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2590 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2591 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2592 call the sysdep functions with deferred ints.
2593 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2594 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2595 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2598 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2601 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2603 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2605 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2607 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2610 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2612 * eval.c (scm_lookupcar1): New procedure to cope with a race
2613 condition during lookup (when using threads).
2614 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2615 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2618 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2620 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2621 supplied. (Change from Tim Pierce.)
2623 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2625 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2626 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2627 default and not `()'. `#f' is the canonical non-value in Scheme,
2630 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2632 * struct.c (struct_printer): New variable that holds a handle on
2633 the Scheme variable *struct-printer*. This variable can be set by
2634 Scheme code to override the printing of structures.
2635 (scm_print_struct): If struct_printer is set, call it. If it is
2636 not set, or returns #f, print the structure in the old fashion.
2637 Include "eval.h" for scm_apply.
2639 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2641 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2642 scm_struct_i_n_words to get the number of fields, not
2643 -scm_struct_n_extra_words.
2645 On the route to fancier struct printing:
2646 * struct.c (scm_print_struct): New function to print a structure.
2647 Include "genio.h" to support it. This function doesn't do
2648 anything interesting right now, but I think it should be here
2650 * struct.h: Include "print.h" and add prototype for
2652 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2653 print structures ourself.
2655 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2657 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2658 before applying the handler in case it doesn't return.
2660 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2662 * scmsigs.h, async.h: updated.
2664 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2667 * posix.c (scm_uname): interpret only negative values as an error.
2668 Solaris normally returns a positive value.
2670 * script.c (scm_compile_shell_switches): if we are not going into
2671 an interactive repl, set scm_mask_ints to zero so that asyncs can
2674 * simpos.c (scm_system): don't ignore/unignore signals around
2677 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2680 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2681 done in boot-9.scm instead.
2683 * scmsigs.c, async.c: Major rewriting of signal handling code.
2684 (scm_sigaction): new procedure.
2685 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2687 (scm_raise): return unspecified, throw error on failure.
2689 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2691 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2692 feature, to help boot-9.scm decide whether to import the regex
2695 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2697 * eval.c: Include scmconfig.h at the beginning of the file so that
2698 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2701 * regex-posix.c: #include "_scm.h" before conditionally #including
2702 <regex.h>; the former defines HAVE_REGCOMP.
2704 * regex-posix.c: #include <regex.h> conditionally, so the file is
2705 CPP'able (for dependency scanning) even on systems that don't have
2708 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2710 Add new R4RS-compliant syntax for keywords.
2711 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2712 regardless of the setting of the `keywords' read option.
2713 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2714 can be re-read no matter what the setting of the `keywords' read
2717 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2719 Add support for POSIX regular expressions.
2721 * regex-posix.c, regex-posix.h: New files. (Some code
2722 is taken liberally from rx/rgx.c in the old Guile dist.)
2724 * init.c: Include regex-posix.h.
2725 (scm_boot_guile_1): Call scm_init_regex_posix.
2727 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2728 Add regex-posix.[ch] sources.
2729 * Makefile.in: Regenerated.
2731 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2732 to do this automatically? It didn't for me, bleh.)
2734 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2736 * fports.c (print_pipe_port): New function.
2737 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2738 latter doesn't even take the right arguments.
2740 * Makefile.am: Increment shared lib revision number. I think
2741 sometimes the uninstalled Guile finds the installed shared lib;
2742 Gord says doing this might help. As things turned out, I can't
2743 say whether it does.
2744 * Makefile.in: Regenerated.
2746 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2747 passing it as the closure argument to scm_boot_guile. (Bill
2750 * ports.c (print_void_port, putc_void_port, puts_void_port,
2751 write_void_port, flush_void_port, getc_void_port, close_void_port,
2752 noop0): Use ANSI prototypes instead of K&R declarations, so the
2753 initialization of void_port_ptob gets aggressively type-checked.
2754 Fix arguments of print_void_port and write_void_port. (Bill

2788 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2790 * script.c (scm_find_executable): Use prototype-style definition
2791 here; apparently it's not quite right to have const in a prototype
2792 and then use a K&R declaration. I wonder if stuff like this will
2793 go away if we compile with -Wrequire-prototypes, or whatever that
2794 is... (Bernard URBAN)
2796 * scmhob.h: New text from Bernard URBAN.
2798 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2800 * script.c: Don't #define const on hpux. Configure takes care of
2801 this. (Thanks to Larry Schwimmer.)
2803 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2804 decide whether to #include <unistd.h>, instead of listing a bunch
2805 of systems. Don't #include stdio twice. Removed dyked-out
2806 definition of scm_find_impl_file.
2808 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2810 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2811 library version info to 1:0.
2812 * Makefile.in: Regenerated.

2818 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2819 throw.c: Update copyright years; these files have been worked on
2820 significantly in 1997, but only had copyright years for 1996.
2821 Also, change name of copyright holder on some from Mikael
2822 Djurfeldt to Free Software Foundation; he has signed papers
2823 assigning the changes to the FSF.
2825 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2826 reason not to give the user the option.
2828 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2829 Return #f on end-of-file when scanning table (i.e. when called
2830 with no arguments). Try to catch errors, when we can.
2831 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2833 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2834 external declarations. These are useful.
2836 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2838 * posix.c: don't include <sys/select.h> or define macros for
2839 select, since they were not used in this file.
2841 * filesys.c (scm_select): make the fifth parameter microseconds,
2842 not milliseconds. let the fourth parameter be either a real value
2843 or an integer or #f. The first, second and third arguments can
2844 now be vectors: the type of the corresponding return set will be
2846 (set_element, get_element): new static procedures.
2848 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2850 * strports.c (scm_eval_string): New function.
2851 (scm_eval_0str): Trivially re-implemented in terms of
2853 * strports.h (scm_eval_string): New extern decl.
2855 * net_db.c (h_errno): Add extern decl for this.
2857 * fports.c (local_pclose): New function.
2858 (scm_pipob): Use it in the initializer here.
2861 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2862 Use a meaningful error message when signalling an error. For
2863 this, scm_gethost must check h_errno rather than errno.
2865 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2867 * Makefile.in: Regenerated, using automake-1.1p.
2869 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2871 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2872 not SCM_UNSPECIFIED.
2874 * script.c (scm_compile_shell_switches): don't append (quit) if
2876 (scm_shell): call scm_exit_status and exit on the result of the
2879 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2881 Ensure that shared substrings are handled properly when passed to
2882 a system call or other foreign function. Many thanks to Tim
2884 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2885 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2886 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2887 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2902 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2904 * error.c (scm_error): Add newline to error message.
2906 * init.c (scm_init_standard_ports): Doc fix.
2908 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2910 * dynl-shl.c: Completely replaced with new code from Bernard
2913 * script.c (scm_ice_9_already_loaded): New variable.
2914 (scm_compile_shell_switches): Use it.
2916 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * filesys.c (scm_input_waiting_p): add missing third argument to

2922 calling gmtime in case they share a buffer.
2923 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE

2928 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2930 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2932 * Makefile.am (check-local): New target, which causes 'make check'
2933 to run gh_test_c and gh_test_repl, with some trivial input.
2934 * Makefile.in: Rgnrtd.
2936 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2938 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2941 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2943 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2944 sure how this was supposed to work.
2945 (scm_async_click): don't send SCM_TICK_SIGNAL.
2946 (scm_init_async): don't initialize %tick-thunk.
2948 * the following change doesn't affect the Scheme interface:
2949 gc-thunk is called at the end of garbage collection. however it's
2950 no longer implemented by pretending it's a signal.
2952 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2953 system async corresponding to scm_gc_thunk.
2954 * async.h: declare scm_gc_async.
2955 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2956 gc-thunk directly, instead of going through a signal handler.
2957 (scm_gc_async): new variable, points to the GC system-async.
2958 (scm_init_async): save the GC async as scm_gc_async instead
2959 of using system_signal_asyncs.
2960 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2962 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2964 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2965 Don't screw up if we're interrupted.
2966 * Makefile.in: Regeneradet.
2968 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2970 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2972 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2973 we're not using AM_INIT_GUILE_MODULE any more.
2974 * Makefile.in: Reneregated.
2976 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2978 Functions for finding variable bindings, grace à Tim Pierce.
2979 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2980 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2982 Get 'make dist' to work again.
2983 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2984 * Makefile.in: Regenerated, like a surry without a fringe on top.
2986 Changes for reduced Guile distribution: one configure script,
2988 * configure.in, configure: Removed.
2989 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2990 real configure script lives.
2991 * Makefile.in, scmconfig.h.in: Regenerated.
2993 * init.c: #include "script.h", to get prototype for script.c's
2996 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2998 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2999 scm_must_malloc, not raw malloc.
3001 * script.c (scm_compile_shell_switches): Dyke out debugging output
3004 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3006 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3008 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3009 system has them. Hope this is safe. Previously
3010 sys/timeb.h was included if HAVE_FTIME was defined or if
3011 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3012 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3014 * ioext.c (scm_setfileno): add missing third argument to
3015 scm_misc_error call.
3017 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3019 * eq.c (scm_equal_p): Correctly compare strings of different
3020 varieties. (Thanks to Tim Pierce.)
3022 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3024 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3025 #! block comment must occur on a line all by itself.
3027 Move most of the guts of shell command processing into libguile,
3028 so guile.c can be very small (and eventuallly auto-generated. (I
3029 mean, generated mechanically, not self-generated. Hmm.))
3030 * guile.c, script.c, script.h: New source files.
3031 * init.c (scm_boot_guile_1): Call scm_init_script.
3032 * libguile.h: #include "script.h".
3033 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3034 targets, for new executable.
3035 (libguile_la_SOURCES): Mention script.c.
3036 (modinclude_HEADERS): Add script.h.
3037 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3038 not dynamic linking is enabled. This is because we're generating
3039 executables now. Move CY_AC_WITH_THREADS call after those, so the
3040 values of cy_cv_threads_libs captures the libs chosen above.
3041 * Makefile.in, configure, aclocal.m4: Regenerated.
3043 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3044 We don't maintain this interface any more, and it just confuses
3047 * alloca.c: #include <scmconfig.h>, not <config.h>.
3048 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3049 it'll get included in disties.
3051 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3053 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3054 be distributed, because they confuse people.
3055 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3057 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3059 * configure.in: check for presence of gethostent (not present on
3060 OpenBSD by default).
3061 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3062 * configure, scmconfig.h.in: Regenerated.
3064 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3066 * backtrace.c (scm_backtrace): Split message string across
3067 newlines properly. GCC is more tolerant of this than other

3076 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3078 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3079 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3080 coop-threads.c.cygnus, coop-threads.h.cygnus.
3081 * configure.in: If we're using threads, include threads.o in
3083 * _scm.h, libguile.h: threads.h lives in this directory now.
3084 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3085 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3086 currently used, but brought along for information's sake.
3087 * ChangeLog-threads: log from old 'threads' directory.
3088 * Makefile.in, configure: Rebuilt.
3090 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3092 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3095 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3097 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3099 Merge GH interface library into libguile.
3100 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3101 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3102 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3103 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3105 (EXTRA_libguile_la_SOURCES): ... here.
3106 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3107 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3108 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3109 New variables, describing how to build the gh test programs.
3110 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3111 build the test programs, and we probably should have been linking
3112 libguile.la against them all along, to support AIX shared libs.
3113 Add cflags for threads to CFLAGS; add libs for threads to new
3114 variable THREAD_LIBS, used in Makefile.am.
3115 * ChangeLog-gh: log from old `gh' subdirectory.
3116 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3118 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3120 * acconfig.h: Undo change of Apr 9; including the definition of
3121 PACKAGE in the guile headers conflicts with applications' own
3123 * scmconfig.h.in: Regenerated.
3125 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3134 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3136 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3137 have S_IFSOCK. This is the case under Ultrix.
3139 * posix.c (scm_status_exit_val, scm_status_exit_val,
3140 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3141 Ultrix versions of WIFSTOPPED, etc., which assume that their
3142 arguments are lvalues (hmm).
3144 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3146 * eval.c: Doc fixes.
3148 * throw.c: Doc fixes; rearranged.
3150 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3152 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3154 * acconfig.h: Added entry for PACKAGE.
3155 * scmconfig.h.in: Regenerated.
3157 Changes to work with automake-1.1n, which has better libtool support.
3158 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3159 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3161 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3163 * Makefile.in: Rebuild.
3165 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3167 * stime.c (scm_mktime): take an optional zone argument.
3168 (scm_localtime): check putenv return value.
3169 (scm_strftime, scm_strptime): moved from posix.c. move #include
3171 stime.h, posix.h: update prototypes.
3172 (bdtime2c, setzone, restorezone): new static procedures.
3173 (scm_mktime, scm_strftime): use them.
3174 (scm_strftime): don't call mktime before strftime. Use
3175 filltime for return value.
3176 (filltime): convert NULL zname to #f.
3177 (scm_strptime): return a count of characters consumed, not
3178 the remaining string.
3180 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3182 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3183 (scm_mktime): likewise.
3185 Uncomment localtime and mktime.
3187 * configure.in: add AC_STRUCT_TIMEZONE.
3189 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3191 * stime.c (scm_init_stime): don't define ticks/sec.
3192 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3193 return value problem and is still portable.)
3195 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3197 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3198 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3199 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3200 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3201 cpp_err_symbols.c): Corresponding changes.
3202 * Makefile.in: Regenerated.
3204 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3206 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3207 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3208 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3209 * putenv.c: new file, from sh-utils 1.12.
3211 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3212 since allocation isn't for Scheme objects.
3213 (scm_putenv): copy strings before placing in the environment.
3215 * stime.c (scm_current_time): throw an error if time returns -1,
3216 instead of returning #f.
3217 (scm_get_internal_real_time, scm_get_internal_real_time): use
3218 scm_long2num for return value instead of SCM_MAKINUM.
3220 * stime.h: prototypes updated.
3222 * stime.c (scm_time_in_msec): apparently unused, deleted.
3224 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3226 * configure.in: check for gettimeofday.
3228 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3229 which may be more usefully portable than a gettimeofday interface.
3231 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3233 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

3239 * stime.c (filltime): recovered static procedure.
3240 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

3244 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3246 * posix.c (scm_mknod): split the mode argument into type and perms
3247 arguments, like the extra fields returned by stat.
3249 * fports.c (scm_pipob): set the close, free and print procedures.
3250 (scm_close_pipe): new procedure.
3252 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3253 define them in boot-9.scm
3255 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3257 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3258 wan't defined. Don't include fd.h.
3260 * Previously fd.h was regenerated whenever configure was run,
3261 forcing a couple of files to be recompiled.
3263 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3264 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3265 Check for _fileno as well as _file.
3267 * ioext.c: don't fd.h.
3268 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3271 * Change the stratigy for getting information about errno
3272 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3273 generating lists of symbols during the build process, which will
3274 not always work, include comprehensive lists in the distribution.
3275 To help keep the lists up to date, the "check_signals" and
3276 "check_errnos" make targets can be used.
3278 * configure.in: don't check for a command to extract errno codes.
3279 * Makefile.am: update file lists, remove errnos.list and errnos.c
3280 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3281 check_errnos targets.
3282 (CLEANFILES): remove errnos.c and errnos.list, add
3283 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3284 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3285 * errnos.default: deleted.
3286 * cpp_signal.c: new file.
3287 * cpp_errno.c: renamed from errnos_get.c.
3288 * cpp_err_symbols, cpp_sig_symbols: new files.
3289 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3290 * error.c (scm_init_error): #include cpp_err_symbols instead of
3292 * posix.c (scm_init_posix): don't intern signal symbols. #include
3295 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3297 * strop.c (scm_i_index): allow the lower bound to be equal to the
3298 length of the string, so a null string doesn't always give an error.
3300 * posix.h: new prototypes.
3301 * posix.c (scm_status_exit_val, scm_status_term_sig,
3302 scm_status_stop_sig): new functions, as in scsh. They break down
3303 process status values as returned by waitpid.
3305 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3307 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3308 configure doesn't know about it.
3310 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3312 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3314 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3315 which defines C variables with global linkage.
3317 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3319 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3322 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3324 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3325 has time to check why this doesn't work well with continuations.
3327 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3329 * Fix shell syntax error; some shells won't tolerate
3330 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3332 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3334 * posix.c (scm_uname): throw an error if uname fails instead
3337 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3339 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3342 * async.c (scm_ints_disabled): definition moved from error.c.
3344 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3346 * acconfig.h: Removed PACKAGE.
3348 * scmconfig.h.in: Regenerated.
3350 * snarf.h: g++ says it's non-portable not to specify the first
3351 argument in a varargs declaration. I introduced the first
3352 argument by using preprocessor conditionals.
3354 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3356 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3357 (scm_freopen): use RO string macros for filename and modes.
3358 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

3361 (scm_mknod): use RO string macros for path.
3363 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3364 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3366 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3367 use SCM_ROSTRINGP and SCM_ROCHARS.

3371 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3374 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3376 support for byte vectors.
3378 * print.c (scm_iprin1): Limit number of vector elements printed
3379 according to pstate->length.
3381 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3386 * error.h: prototype for scm_error_scm.
3388 * error.c (scm_error_scm): new procedure, reimplements scm-error
3389 in C and uses scm_error.
3391 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3393 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3394 pointer to the Scheme variable read-hash-procedures and intern it
3395 in scm_init_read. Modify scm_read_hash_extend and
3396 scm_get_hash_procedure to use the pointer.
3398 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3400 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3401 (SCM_KEYWORD_STYLE): defined.
3403 * read.c (scm_read_opts): add a keywords option. This isn't a
3404 boolean option, in case someone wants to add support for DSSSL
3406 Setup scm_keyword_prefix symbol.
3407 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3409 I've left keyword support disabled by default, since it doesn't
3410 seem to break the module system and it gives R4RS standard behaviour.
3411 It can be reactivated with (read-set! keywords 'prefix).
3413 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3415 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3416 before constructing arbiter.
3418 * eval.c (scm_m_define): Bugfix: Check that the object is a
3419 closure before setting the procedure property!
3421 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3423 * ports.c: Removed `ungetc-char-ready?'.
3425 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3427 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3428 (idea from Mikael: make it a pair so scm_permanent object only
3430 (scm_read_hash_extend): don't call scm_permanent_object.
3431 (ideas from Mikael): if chr is already in the list, replace its
3432 procedure instead of appending it again. If proc is #f, remove
3434 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3436 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3438 * gdbint.c (gdb_read): update scm_lreadr usage.
3440 * load.h: update prototypes.
3442 * load.c (scm_primitive_load, scm_read_and_eval_x,
3443 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3445 * read.h: add prototype for scm_read_hash_extend. Change args for
3448 * read.c (scm_read_hash_procedures): new variable.
3449 (scm_read_hash_extend): new procedure.
3450 (scm_get_hash_procedure): new procedure.
3451 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3452 for extended # processing.
3453 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3454 scm_read_token): remove case_i, sharp arguments. Change callers.
3456 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3458 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3459 (SCM_CASE_INSENSITIVE_P): define.
3461 * read.c: add case-insensitive option to scm_read_opts.
3462 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3463 to determine whether to convert symbol case.
3464 (default_case_i): definition removed.
3465 * read.c (scm_read_token): if case_i, downcase ic before doing
3468 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3470 * configure.in: Added configuration option `guile-debug'.
3471 Configure with --enable-guile-debug if you want a bunch of extra
3472 functions used for debugging when developing Guile.
3474 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3476 * procs.c (make-cclo): New undocumented debugging procedure: Make
3477 compiled closure with internal procedure PROC and length LENGTH.
3478 Only compiled if GUILE_DEBUG is defined.
3480 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3482 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3484 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3486 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3487 with 3 or more args internally to the evaluator.
3489 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3491 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3492 with 3 or more args internally to the evaluator. This is mainly
3493 because we don't want to pass entry and exit points of the
3494 debug support twice, but it also seems to increase the speed of
3495 the evaluator for such calls (e. g. (+ 1 2 3)).
3497 * backtrace.c (scm_display_application): New procedure:
3498 display-application; Set fancy printing parameters individually
3499 for different types of display (backtrace, error, application).
3500 (These should of course be customizable!)
3502 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3503 clear the CHECK-flags.
3505 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3507 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3509 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3511 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3512 from pairs with a GLOC in the car.
3514 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3515 otherwise `symbol-hash' will behave badly.
3516 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3517 we get segmentation fault!
3519 * symbols.c: Added #include "weaks.h". New functions:
3520 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3521 moved to an extraneous library when we split libguile.)
3523 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3525 * filesys.c (scm_stat): stat now takes fport arguments too as
3526 documented in the manual.
3528 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3530 * debug.c (scm_single_step): Bugfix: Call continuation with
3531 scm_call_continuation instead of throwing to it.
3533 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3535 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3536 argument wasn't declared to be optional.
3538 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * stime.c (scm_init_stime): Add feature "current-time".
3542 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3544 * throw.h: prototype for scm_exit_status.
3545 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3546 args to derive an exit status. Allows (quit) to work from a
3548 (scm_exit_status): new function.
3551 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3553 * eval.c (scm_deval): Removed some old code.
3554 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3556 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3559 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3562 * procs.c: Introduce the existent C function scm_thunk_p at the
3563 Scheme level as well.
3565 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3567 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3568 used from C to easily lookup the value of a symbol in the current
3571 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3573 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3574 scm_init_unif in this file. This will also fix a previous problem
3577 * configure.in: Added AM_MAINTAINER_MODE
3579 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3581 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3584 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3586 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3587 source files that are not always included in libguile but should
3588 have their dependencies calculated by automake. This variable is
3589 recognized by automake, no further magic is needed.
3590 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3591 to deal exclusively with *.lo files, as it seems. The *.o files
3592 are built automatically when the corresponding *.lo file gets
3595 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3597 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3600 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3602 * unif.c (scm_array_set_x): minor change to argument error checking.
3604 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3606 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3607 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3608 They should only be included in the library at configure.in's
3610 (libguile_la_LDADD): Include the appropriate .lo files here.
3611 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3612 so we know when to build them (and their .lo bretheren).
3613 * configure.in (LIBLOBJS): New substituted variable. We let
3614 configure decide which .o files to include in LIBOBJS, and then
3615 put the corresponding list of .lo files in LIBLOBJS. The latter
3616 is what we pass to libtool.
3617 * Makefile.in, configure: regenerated.
3619 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3621 * symbols.c (scm_sysintern0): New function. Contains the core of
3622 old scm_sysintern but doesn't take a second value argument.
3623 (scm_sysintern): Now uses scm_sysintern0.
3624 (scm_sysintern_no_module_lookup): Renamed to
3625 scm_sysintern0_no_module_lookup and doesn't take a second value
3626 argument any longer.
3628 * symbols.h (scm_sysintern0: Added declaration.
3630 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3631 scm_sysintern when interning option keys. Otherwise we risk
3632 destroying the values of already interned variables.
3634 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3635 scheme-level boolean (use SCM_NFALSEP).
3637 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3639 (scm_backtrace): New function. (C version of old function from
3640 boot-9.scm) Motivation: Make it possible to display backtraces
3641 without depending on boot-9.scm. (I'm uncertain if this
3642 motivation is good enough...)
3644 * root.h (scm_root_state): Add member the_last_stack_var.
3645 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3647 * root.c (mark_root): Mark scm_the_last_stack_var.
3649 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3652 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3654 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3655 1. mark_lazy_catch didn't mark the smob.
3656 2. Both functions above have standard variants:
3657 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3658 free_lazy_catch --> scm_free0.
3660 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3662 * throw.c (scm_internal_lazy_catch): New function.
3663 (scm_lazy_catch): Rewritten to use it.
3664 (scm_ithrow): Handle the new lazy catch representation.
3665 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3666 that doesn't have a jmpbuf is a lazy catch clause.
3667 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3668 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3669 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3671 (scm_init_throw): Register the new lazy-catch smob type.
3672 * throw.h (scm_internal_lazy_catch): decl for new function.
3674 * throw.c (scm_internal_catch): Doc fixes.
3676 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3677 configure.in. Including this might cause problems if applications
3678 that link against libguile include their own copies of alloca, but
3679 if they're using autoconf, they should be adding libguile to LIBS
3680 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3681 the copy in libguile, and things will be okay. (I think.)
3683 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3685 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3687 strop.h: move prototypes too.
3689 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3691 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3694 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3695 etc. I deleted them from filesys.c long ago, but didn't
3696 notice they were here too (although ineffective since
3697 sys/stat.h wasn't included).
3699 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3701 * eval.c: Don't define alloca in GCC case. gcc will automatically
3702 use __builtin_alloca if appropriate.
3704 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3706 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3707 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3708 that values of automatic variables are preserved. See comments
3709 for safe_setjmp for details.
3711 Change from Thomas Morgan:
3712 * variable.c: Include eq.h.
3713 (var_equal): New function.
3714 (variable_smob): Use var_equal as the discriminator for variables.
3716 * throw.c (s_throw): Remove extraneous declaration.
3718 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3719 * eval.c: Add necessary CPP cruft to support that.
3720 * configure, Makefile.in, scmconfig.h.in: regenerated.
3722 Change from Thomas Morgan:
3723 * procprop.c (scm_procedure_properties): Convert the Scheme
3724 boolean returned by scm_procedure_p into a C boolean before using
3725 it as a condition for SCM_ASSERT.
3726 (scm_procedure_property): Likewise.
3728 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3729 indications of Unixness.
3732 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3734 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3736 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3738 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3739 "unknown # object" error messages.
3741 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3742 (scm_i_index) and declare it static. Add a 'direction' argument
3743 to indicate what way the search should go.
3744 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3746 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3747 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3749 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3751 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3753 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3754 to avoid clash with various scsh forks.
3756 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3758 The following two changes (ramap.c, throw.c) are motivated by the
3759 apparent unportability of forward declarations of static arrays of
3760 the form `static foo bar[];'.
3762 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3763 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3765 * throw.c (scm_throw): Moved above scm_ithrow.
3767 * options.h: Removed the extern declarations of scm_yes_sym and
3768 scm_no_sym since these are static.
3770 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3772 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3774 * Makefile.am: remove AWK=@AWK@.
3775 Add a rule for generating errnos.list.
3776 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3778 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3779 don't extract errnos, just set a variable (avoids the
3780 need to recompile error.c just because configure is run.)
3782 * unif.h: update prototypes.
3783 * unif.c (scm_uniform_array_read,write): change the offset and
3784 length arguments to start and end, for consistency.
3786 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3788 * ioext.h: update prototypes.
3789 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3790 scm_read_line_x, it's a more general procedure using an
3791 interface from scsh. read-line and read-line! are now defined
3793 Note that the new read-line trims the terminator
3794 by default, previously it was appended to the returned string. An
3795 optional argument specifies how to process the terminator (scsh
3796 compatible). For the old behaviour: (read-line port 'concat).
3797 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3798 returns a pair, but is converted to multiple values if the scsh
3801 socket.h: update prototypes.
3802 * socket.c (scm_recvfrom): for consistency with other procedures,
3803 take start and end as separate optional arguments.
3804 (scm_recv, scm_recvfrom): don't allow the second argument
3805 to be a size, only a buffer. Change the scheme names to
3806 recv! and recvfrom!. Don't return the buffer.
3808 * ioext.h, posix.h: move prototypes too.
3809 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3810 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3811 "read.h" and "unif.h".
3812 * ioext.c: include "chars.h"
3814 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3816 * dynl.c: The dynamic linking and module registration functions
3817 are now defined even when dynamic linking is not available for the
3818 host system. Some of their functionality can be done without
3819 dynamic linking; when it's really needed, they throw errors.
3821 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3823 * configure.in: Only define DYNAMIC_LINKING when one of the system
3824 dependent functions is detected.
3825 * dynl.c (scm_dynamic_func): New function to get the address of a
3826 function in a dynamic object.
3827 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3828 produced by scm_dynamic_func as the thing to call.
3830 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3832 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3833 (scm_register_module_xxx, scm_registered_modules,
3834 scm_clear_registered_modules): New functions.
3836 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3838 * symbols.c (scm_sysintern): Renamed to
3839 scm_sysintern_no_module_lookup.
3840 (scm_sysintern): New function to take the place of the old
3841 scm_sysintern. It uses the current toplevel lookup closure to give
3842 the symbol its value. This is a temporary hack to put packages
3843 like gtcltk into their own module.
3844 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3845 us whether `scm_top_level_lookup_closure_var' has been initialized
3847 * eval.c (scm_init_eval): Set it.
3849 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3851 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3852 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3854 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3856 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3857 scm_sys_dup): deleted: FD capability will be added to other
3859 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3860 scm_fd_free, fd_smob, scm_intern_fd.
3861 (scm_open): renamed from scm_sys_open. Return a port instead of
3862 an FD object. Make the mode argument optional.
3863 (scm_sys_create): deleted, it's just a special case of open.
3864 (scm_init_filesys): move interning of constants O_CREAT etc.,
3865 here (were previously using SCM_CONST_LONG macro).
3866 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3868 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3869 include "fports.h" and <stdio.h>
3870 (scm_stat, scm_select): don't support FD objects.
3872 * error.h: adjust scm_syserror_msg prototype.
3873 * error.c (scm_syserror_msg): take an extra argument for errno.
3874 Using the global value didn't always work, since it could be
3875 reset by procedure calls in the message or args arguments.
3877 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3878 I don't understand why the check was there (and what about the
3881 * strop.c (scm_string_copy): allow shared substrings to be copied.
3883 * unif.h: corresponding change to prototypes.
3884 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3885 recognize two new optional arguments: offset and length. Allow
3886 the port argument to be an integer (file descriptor, for scsh).
3887 Include <unistd.h> for "read" prototype.
3889 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3891 * socket.c: don't include filesys.h.
3893 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3895 * Makefile.am: add AWK=@AWK@ (?)
3897 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3899 Add a rule to generate errnos.c from errnos.
3900 * error.c (scm_init_error): include errnos.c.
3901 * errnos_cnvt.awk: new file, converts the list of errno codes to
3903 * errnos_get.c: new file.
3904 * errnos.default: new file, contains errnos to try if they can't
3905 be extracted from errno.h.
3906 * configure.in: if using GCC, try and extract errno codes from
3910 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3912 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3913 * Makefile.am: Made libguile into a libtool library.
3914 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3915 Set libtool_libs to indicate that libguile is a libtool library.
3916 See guile/ChangeLog for details.
3917 * .cvsignore: ignore "*.lo", the libtool library objects.
3919 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3921 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3922 use htons in getservbyport argument.
3924 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3926 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3927 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3930 * objprop.c (scm_object_property): No need to take the CDR of the
3931 value returned by scm_object_properties, since Aug 20 change.
3933 * configure.in: When checking for struct linger, #include
3934 <sys/types.h> as well as <sys/socket.h>. I've never known
3935 <sys/types.h> to cause any portability problems, and Solaris's
3936 <sys/socket.h> needs it.
3937 * configure: Rebuilt.
3939 I think the Sun compiler has chosen a perverse way to interpret
3940 ANSI declarations combined with K&R definitions. We'll
3941 appease it a little bit. But when it invades France, we fight.
3942 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3943 * print.h (scm_iprlist): Here too.
3944 * numbers.c (scm_divbigdig): Change definition to match
3945 declaration in numbers.h.
3946 * unif.c (scm_makflo): Change definition to match declaration in
3949 * init.c (scm_boot_guile): Don't return the value of
3950 scm_boot_guile_1. This function doesn't return a value;
3951 scm_boot_guile_1 doesn't return a value (or return at all).
3953 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3956 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3957 compile. I have a feeling this function is a bad idea anyway ---
3958 one should always test for features, not systems.
3960 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3961 semicolons. Only pure luck kept this from being noticed earlier.
3963 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3965 * socket.c (scm_recvfrom): Added missing semicolon.
3967 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3969 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3970 the buffer and start and end positions for scsh networking
3973 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3975 * configure.in: Revert previous change to this file; the problem
3976 is due to transient automake weirdness.
3977 * configure: Rebuilt.
3979 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3980 PLUGIN/guile.libs. configure generates the latter from the former.
3981 * Makefile.in: Rebuilt.
3983 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3984 need this if we install scripts, like guile-snarf.
3985 * configure: Rebuilt.
3987 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3989 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3991 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3993 * socket.c (scm_addr_vector): fix faulty scm_listify.
3995 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3997 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3998 style block comment is no longer considered an error.
4000 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4002 * PLUGIN/guile.libs.in: New file.
4003 * PLUGIN/guile.libs: Removed from repository.
4004 * configure.in: Create PLUGIN/guile.libs from
4005 PLUGIN/guile.libs.in. This is for including additonal libraries
4006 needed for dynamic linking.
4007 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4008 instead of PLUGIN/guile.libs.
4010 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4012 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4014 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4015 occurrences of the given element from the list, not just the
4016 first. This is how the Emacs Lisp functions behave, how the
4017 analogous Common Lisp functions behave, and (I believe) how the
4018 older Maclisp functions worked. I realize that this change may
4019 break code, but it seemed better to break it before the Guile
4022 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4023 Their prototypes were already present in gc.h, but they weren't
4025 (scm_init_storage): Initialize scm_protects.
4026 * root.c (scm_protects): New element of scm_sys_protects.
4028 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4030 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4032 * libguile.h: Added #include "libguile/net_db.h".
4034 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4035 30 change. That file is only meant for communication between the
4036 configuration process and load.c. If code linked against libguile
4037 wants to get at the paths mentioned in libpath.h, it can call
4038 functions declared in load.h.
4040 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4042 * libguile.h: Removed #include "libguile/fdsocket.h"
4044 * net_db.c: Added #include <sys/socket.h>.
4046 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4048 * filesys.c (scm_input_waiting_p): use select in preference to
4049 FIONREAD, since the latter doesn't detect EOF.
4050 Throw error if neither select nor FIONREAD available.
4052 * socket.c (scm_connect): take a port, not a fd object.
4053 (scm_fill_sockaddr): throw an error if fam is not recognised.
4054 (scm_bind): use scm_fill_sockaddr.
4055 (scm_listen): take a port, not a fd object.
4056 (scm_accept): take and return a port. return #f in the car if
4057 address can't be got
4058 (scm_sock_fd_to_port): new procedure.
4059 (scm_socket): use scm_sock_fd_to_port.
4060 (scm_addr_vector): throw error if unrecognised address type.
4061 take an extra argument with the calling procedure name.
4062 (scm_getsockname): take a port. return #f if address can't be got.
4063 (scm_getpeername): take a port. return #f if address can't be got.
4064 (scm_recvfrom): take a port. return #f for address component if can't
4066 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4067 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4069 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4071 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4072 use separate data pointers, to allow them to be designed
4073 independently and reused.
4074 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4075 Renamed from catch_body, catch_handler, and uncaught_throw; made
4077 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4079 (scm_catch): Use the above.
4080 (scm_throw): Don't bother printing a message for an uncaught
4081 throw; we establish a default handler in init.
4082 * throw.h (scm_internal_catch): Prototype updated.
4083 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4085 (struct scm_body_thunk_data): New structure, used as data
4086 argument to scm_body_thunk.
4087 * init.c (struct main_func_closure): New structure, packaging up
4088 the data to pass to the user's main function.
4089 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4090 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4091 scm_internal_catch to establish a catch-all handler, using
4092 scm_handle_by_message. This replaces the special-case code in
4094 (invoke_main_func): Body function for scm_internal_catch; invoke
4095 the user's main function, using the main_func_closure pointer to
4096 decide what to pass it.
4097 * root.c (struct cwdr_body_data): Remove handler_proc member.
4098 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4099 (cwdr_handler): Removed.
4101 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4103 * socket.h (SCM_P): update bind prototype.
4104 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4105 include "feature.h".
4106 (scm_socket): return a port, not a file descriptor object.
4107 include "fports.h" and <unistd.h>
4108 (scm_bind): take a port, not a file descriptor object.
4109 take an extra argument for address args.
4111 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4112 INADDR_NONE, INADDR_LOOPBACK.
4114 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4116 * init.c: include net_db.h and not fdsocket.h.
4117 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4119 * Makefile.am: corresponding changes.
4120 * socket.h: renamed from fdsocket.h, fix names.
4121 * net_db.h: renamed from socket.h, fix names.
4122 * socket.c: renamed from fdsocket.c.
4123 remove _sys from procedure names.
4124 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4125 add "socket" to features list.
4126 * net_db.c: renamed from socket.c.
4127 remove _sys from procedure names.
4128 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4129 add "net-db" to features list.
4130 include "net_db.h". don't include <sys/socket.h> or
4133 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4135 * tags.h (scm_tags): Removed comma at end of last enumerator.
4137 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4139 Don't use GCC extensions to allocate space for debugging frames.
4140 (Here he goes again! Why do we put up with this?!)
4141 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4142 an scm_debug_info structure, not an in-line array of them. Add
4143 'info' member, to say how many vect elements we've used, for eval
4145 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4146 a new variable debug_info_end to mark the end of vect, instead of
4147 the address of the 'info' pointer itself.
4148 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4149 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4150 (SCM_APPLY): Explicitly allocate space for debug.vect.
4151 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4152 * stacks.c: Adjusted for new debug frame structure.
4153 (RELOC_INFO, RELOC_FRAME): New macros.
4154 (stack_depth, read_frames): Use them, and new scm_debug_frame
4155 element 'info', instead of magically knowing that eval frames have
4156 an info pointer sitting after vect.
4157 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4159 (scm_init_stacks): Formatting tweaks.
4161 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4163 Give GCC more control flow information, so it can be sure that
4164 variables aren't used uninitialized.
4165 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4166 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4167 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4168 scm_misc_error): Tell GCC that these functions never return.
4169 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4170 out the field type, call abort if SCM_ASSERT returns, to placate
4172 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4173 scm_wta ever returns. We can't handle this case anyway, and this
4174 gives the optimizer more information.
4175 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4176 scm_wta ever returns.
4178 In some cases, the code is fine, but GCC isn't smart enough to
4179 figure that out; this usually happens when one variable is only
4180 initialized and used when a particular condition holds true, and
4181 we know that condition will never change within a given invocation
4182 of the function. In this case, we simply initialize the variables
4183 to placate the compiler, hopefully to a value which will cause a
4184 crash if it is ever actually used.
4185 * print.c (scm_iprin1): Initialize mw_pos.
4186 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4187 * throw.c (scm_ithrow): Initialize dynpair.
4188 * unif.c (scm_uniform_vector_ref): Initialize cra.
4189 * struct.c (init_struct): Initialize prot.
4190 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4192 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4193 if EXPR contains no expressions.
4195 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4197 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4198 cause an infinite loop (???). So much for the algebraic
4199 equivalency of variable-sized arrays and alloca...
4201 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4203 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4204 a SCM boolean, not a C boolean.
4206 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4208 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4209 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4210 rules for raising scm_mtrigger. Previously, unfortunate but not
4211 unlikely circumstances could result in almost constant invokation
4212 of the gc. Now, this situations should be less likely, but they
4213 are not prevented completely.
4215 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4217 * numbers.c (scm_fuck): Procedure removed; looks like old test
4219 * numbers.h: Prototype removed.
4221 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4223 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4224 array to a pointer, to match my Nov 21 change in eval.c.
4226 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4228 * libguile.h: Added #include "libguile/backtrace.h", #include
4229 "libguile/stacks.h".
4231 * strings.c (scm_string scm_make_string scm_string_ref
4232 scm_string_set_x scm_string_equal_p scm_string_append):
4233 Bugfix according to scm patch from Aubrey Jaffer:
4234 Corrected long-standing
4235 (not (eqv? (integer->char 128)
4236 (string-ref (make-string 1 (integer->char 128)) 0)))
4237 bug found by John Kozak <jk@noontide.demon.co.uk>.
4239 * strports.c, strports.h: Make scm_eval_0str return the value of
4240 the last expression evaluated (previously, it returned void).
4242 * strports.c, strports.h: New function: scm_read_0str. Does what
4245 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4247 * simpos.c (scm_getenv): return #f if string can't be found in the
4248 environment instead of throwing an exception, for compatibility
4249 with numerous other systems.
4251 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4253 * Makefile.am (.c.x): Use guile-snarf.
4254 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4256 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4258 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4260 * backtrace.c (scm_display_error_message): Made non-static, and
4261 renamed from display_error_message.
4262 * backtrace.h (scm_display_error_message): Added extern decl.
4263 * throw.c (uncaught_throw): Use it to display the error message.
4265 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4267 * inet_aton.c: Use #if 0, not #ifdef 0.
4269 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4271 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4272 to convert the returned value.
4273 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4274 the offset argument.
4276 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4278 Add new interface to catch/throw, usable from C as well as
4280 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4281 (scm_internal_catch): New function, replaces...
4282 (scm_catch_apply): Deleted.
4283 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4284 mechanism which is a bit more code, but can be used nicely from C
4285 and implement the Scheme semantics as well.
4286 (scm_internal_catch): This is the replacement; it's named after
4287 the analogous function in Emacs.
4288 (scm_catch): Reimplemented in terms of the above.
4289 (struct catch_body_data, catch_body, catch_handler): New
4290 functions, used by scm_catch.
4291 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4292 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4293 support for new cwdr.
4295 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4298 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4300 * acconfig.h: Added DYNAMIC_LINKING symbol.
4301 * configure.in: Add option and checks for dynamic linking.
4302 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4303 dynl.h: New files for dynamic linking support.
4304 * Makefile.am (libguile_a_SOURCES):
4306 (modinclude_HEADERS): Added "dynl.h".
4307 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4309 * init.c (scm_boot_guile_1): Call
4310 scm_init_dynamic_linking to initialize dynamic linking support.
4312 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4314 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4315 (as we Schemers say). It needs to be global, so that I can tweak
4316 it for the proper operation of unexec.
4317 (scm_boot_guile_1_live): New variable, see above.
4319 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4321 * guile-snarf.sh: Removed.
4322 * PLUGIN/guile.libs: Added dependency for -lm.
4323 * acinclude.m4: Renamed from aclocal.m4.
4324 * PLUGIN/greet: Removed.
4325 * Makefile.am, aclocal.m4: New files.
4326 * configure.in: Updated for Automake.
4328 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4330 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4331 and not top_level_lookup_thunk_var.
4333 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4335 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4337 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4339 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4340 Scheme function, instead of syntax. Single argument is now a
4343 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4345 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4346 scm_ra_divide): Properly terminate statements passed as arguments
4347 to IVDEP macros. (Thanks to Bernard Urban.)
4349 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4350 with non-constant sizes. (Thanks to Bernard Urban.)
4352 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4354 It's an "eval closure", not an "eval thunk." A thunk is a
4355 function of no arguments.
4356 * root.h (struct scm_root_state): Renamed
4357 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4358 (scm_top_level_lookup_closure_var): Renamed from
4359 scm_top_level_lookup_thunk_var.
4360 * root.c (mark_root): Uses changed.
4361 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4362 * init.c (scm_start_stack): Uses changed.
4363 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4364 Change scheme-visible name to *top-level-lookup-closure* from
4365 *top-level-lookup-thunk*.
4367 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4369 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4370 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4372 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4374 * gc.c (struct scm_heap_seg_data): Doc fixes.
4376 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4377 sweeping. Then, prepend each segment's free cells to its
4378 freelist, rather than wiping out the old value. (Thanks to Marius
4381 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4382 scm_check_freelist, scm_debug_newcell): New functions and
4383 variables, for debugging freelist problems.
4384 * pairs.h (SCM_NEWCELL): New debugging version added.
4385 * gc.h (scm_debug_newcell): Added extern declaration, used by
4386 debugging version of SCM_NEWCELL.
4388 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4390 On some systems <libc.h> conflicts with <unistd.h>, and should not
4391 be #included at all.
4392 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4393 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4394 * configure.in: Call it.
4395 * posix.c, filesys.c: Use its results to decide whether or not to
4397 * configure, scmconfig.h.in: Rebuilt with autoconf and
4400 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4402 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4403 pointer to the stdio stream before calling scm_setbuf0, so the
4404 latter will be able to retrieve it. I'm surprised this didn't
4405 segfault earlier. (Thanks to Christopher Lee.)
4407 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4409 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4412 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4414 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4415 number of stack narrowing specifier pairs. The first specifier in
4416 a pair controls inner border, the second the outer border. A
4417 number means cut that number of frames, a procedure object means
4418 cut until that object is found in operator position in a frame.
4420 * root.c (cwdr): Bugfix.
4422 * read.c: Recording of positions disabled by default.
4424 * procs.c (scm_closure_p): New function.
4426 * posix.c (scm_tmpnam): New function.
4428 * load.c: Added #include "throw.h".
4429 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4432 * load.c, load.h (scm_read_and_eval_x): New function.
4434 * eval.c: Renamed debug option "deval" to "debug".
4436 (scm_eval_x): `eval!' is no longer accessible from the scheme
4437 level. Motivation: We can't allow operations which introduce
4438 glocs into the scheme level. Guile's type system can't handle
4439 these as data. Use `eval' or `read-and-eval!' as replacement.
4441 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4442 SCM_CONSP since this is a macro!; Set vframe.prev to
4443 scm_last_debug_frame instead of 0. In this way we can look
4444 "above" the virtual start stack frame if we wish.
4445 (scm_debug_hang): New function: Useful for debugging Guile in
4446 certain tricky situations. Will probably be removed later...
4448 * debug.h: Changed semantics of debug option "backtrace". This
4449 option now only indicates whether we want automatic backtrace at
4452 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4454 * ports.c: #include "filesys.h"
4455 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4457 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4458 Motivation: This is system specific code which is related to file
4459 I/O. It also may use select. Added code by Gary Houston to
4460 detect presence of character in stdio buffers.
4462 * libguile.h: #include "libguile/libpath.h"
4464 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4465 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4466 SCM_SITE_DIR; Install libpath.h among the other include files.
4468 * load.c, load.h (scm_sys_package_data_dir): New function.
4470 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4472 * stacks.h: Bugfix: Don't use tail-array length field as stack
4473 length field! This screwed GC.
4475 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4477 * _scm.h: Added #ifndef around definition of macros min and max.
4479 * __scm.h: Added hooks for threads to plugin to in ints protection
4480 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4481 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4482 the main code in these macros duplicated and spread over multiple
4483 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4484 SCM_THREAD_SWITCHING_CODE.
4486 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4488 * snarf.h: New file.
4489 * guile-snarf.sh: New file.
4490 * Makefile.in (inner_h_files): Added snarf.h
4491 (ancillary, install, uninstall, distclean): Added actions for
4493 (.c.x): Use guile-snarf.
4494 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4495 (gen_c_files): Note that these depend on guile-snarf.
4496 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4497 now in "snarf.h". Added #include "snarf.h" to get them.
4498 * libguile.h: Added #include "snarf.h".
4499 (Patches applied and tweaked by Jim Blandy.)
4501 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4503 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4504 standards suggest against providing prototypes for system
4505 functions. Thanks to Greg Troxel.
4507 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4509 * strports.c (scm_eval_0str): New function.
4510 #include "read.h", to get prototype for scm_read.
4511 * Makefile.in (strports.o): Update dependencies.
4512 * strports.h: New prototype.
4514 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4515 scheme name from "int?" to "integer?". It seems to do the job.
4516 * numbers.h: Rename prototype too.
4517 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4520 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4521 scm_num_eq_p): Rename these according to R4RS conventions: call
4522 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4523 to making libguile R4RS compliant without ice-9...
4525 * load.c (scm_sys_search_load_path): Search for files under all
4526 extensions listed in the %load-extensions variable. If FILENAME
4527 is absolute, return it unchanged, without searching the load path.
4528 (scm_loc_load_extensions): New variable, pointing to
4529 %load-extensions' value cell.
4530 (scm_init_load): Initialize it, and the value it points to.
4531 (scm_primitive_load_path): Improve error reporting.
4533 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4534 of new Scheme variable %load-hook.
4535 (scm_primitive_load): Apply %load-hook to filename.
4537 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4539 * configure.in: add tests for figuring out whether buffered data
4540 is available in a FILE structure, which is needed by char-ready.
4542 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4545 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4546 exceptions using misc_error instead of syserror. It seems a bit
4547 odd to throw an exception if a string can't be found in the
4548 environment, but it's consistent with open-file, stat etc.
4549 (simpos.h): remove sys_ from getenv.
4551 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4552 occurs, throw an error instead of returning errno. Return value
4554 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4556 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4558 * filesys.c (scm_stat2scm): derive file type and permissions from
4559 the stat mode and append them to the returned vector.
4560 There isn't much overhead in doing this and it avoids the need to
4561 work with S_IRUSR et al. in Scheme.
4562 Define symbols scm_sym_regular etc.
4563 (scm_init_filesys): don't intern S_IRUSR etc.
4565 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4566 and s_primitive_load_path.
4568 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4570 * error.h: don't declare error symbols. prototype for scm_misc_error.
4572 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4575 * error.c: use SCM_SYMBOL to set up error keys.
4576 scm_misc_error: new procedure.
4578 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4580 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4581 between `#!' and `!#' is ignored.
4582 (skip_scsh_block_comment): New function.
4584 * feature.c (scm_set_program_arguments): New argument, FIRST.
4585 * feature.h: Update prototype.
4586 * init.c (scm_boot_guile_1): Pass new argument to
4587 scm_set_program_arguments.
4589 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4591 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4592 (scm_boot_guile): Call scm_set_program_arguments here, later than
4593 the old initialization.
4595 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4596 initialization procedure.
4597 - Delete in, out, err arguments; there are other perfectly good
4598 ways to override these when desired.
4599 - Delete result argument; this function shouldn't ever return.
4600 - Rename init_func argument to main_func, for less confusion.
4601 - Delete boot_cmd argument; main_func is more general.
4602 -Add 'closure' argument, to help people pass data to main_func
4603 without resorting to global variables.
4604 - Abort if reentered; don't bother returning an error code.
4605 - Call scm_init_standard_ports to set up the default/current
4606 standard ports; no need to pass them to scm_start_stack.
4607 - Remove code to evaluate the boot_cmd, and start the repl; let
4608 the user do something like that in main_func if they want.
4609 - Remove code to package up a return value; main_func can do any
4611 - Call exit (0), instead of returning.
4612 (scm_start_stack): Don't initialize the I/O ports here; that's
4613 weird. Delete in, out, err arguments. Move guts to
4614 scm_init_standard_ports, scm_stdio_to_port.
4615 (scm_init_standard_ports): New function, to set up current and
4616 default standard ports.
4617 (scm_start_stack, scm_restart_stack): Make these static.
4618 * init.h (scm_boot_guile): Adjust declaration.
4619 (scm_start_stack, scm_restart_stack): Remove externally
4620 visible declarations for these.
4621 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4623 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4624 written out several times in scm_start_stack.
4625 * fports.h: New declaration for the above.
4627 * feature.c (scm_set_program_arguments): New function.
4628 * feature.h: New declaration for the above.
4630 * ports.c: Formatting tweak.
4632 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4634 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4635 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4636 for obtaining the address of a car or cdr field. Motivation:
4637 &SCM_CXR make assumptions about the internal structure of the
4640 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4641 Motivation: see SCM_CXRLOC.
4643 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4644 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4645 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4646 Motivation: Safer use. Some other macros are defined in terms of
4647 these operations. If these are defined using the SCM_SETCXR
4648 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4649 to inefficiency and an <e1> with side-effects could potentially
4650 break. Also, these particular operations are heavily utilized in
4651 the garbage collector. In unoptimized code there will be a
4654 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4655 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4656 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4657 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4658 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4659 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4660 vports.c: Cleaned up use of pairs: Don't make any special
4661 assumptions about the internal structure of selectors and
4662 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4663 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4664 (Among other things, this change makes it easier to build Guile
4665 with certain compilers which have problems with casted lvalues.)
4667 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4669 * stacks.c: Improve selection of relevant stack frames when making
4670 a stack object. Introduce one level of indirection in the stack
4671 object to make it possible to "narrow" to a certain region of the
4672 stack. This facilitates making use of more clever algorithms (not
4673 implemented) for selecting relevant frames and gives a cleaner
4674 design since selection of frames can be done independently of
4675 extraction of frames from the real stack.
4676 (scm_stack_id): Also take #t as argument which means look at
4679 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4680 Turn n_tail into an integer directly representing current number
4681 of frames in stack. Add field tail.
4683 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4685 * debug.c (scm_make_memoized): Made it available at scheme level.
4686 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4687 SCM_NIMP before applying heavier predicates in argument checking.
4688 (scm_local_eval): Also take memoized object as argument.
4690 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4691 aren't created with zero length, but should such a strange
4692 creature suddenly turn up...
4694 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4696 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4697 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4699 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4701 * variable.c (scm_make_variable): Make the name hint optional, as
4703 (anonymous_variable_sym): Renamed from variable_sym. All uses
4706 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4707 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4708 of scm_primitive_load_path was also changed to
4709 "primitive-load-path", from "%try-load-path". Callers changed.
4710 We'd like to respect the convention that a function named
4711 "try-mumble" should behave just like the function called "mumble",
4712 but return #f instead of signalling some error.
4713 * load.h: Rename prototypes.
4715 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4717 * print.c (make_print_state, grow_print_state), print.h: Modified
4718 the print state representation: Don't use a tail array for
4719 recording of circular references. Resizing of the print state
4720 structure invalidates the print state pointer. To avoid passing
4721 around an indirect print state reference to all printing
4722 functions, we instead let the print state reference a resizable
4725 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4727 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4728 Don't crash when passed an improper list terminated by a
4729 non-immediate value.
4731 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4733 Allocate data for structures on an eight-byte boundary, as
4734 required by the tagging system.
4735 * struct.c (alloc_struct): New function.
4736 (scm_make_struct, scm_make_vtable_vtable): Call it.
4737 * struct.h (scm_struct_n_extra_words): Bump to 3.
4738 (scm_struct_i_ptr): New "field".
4739 * gc.c (scm_gc_sweep): When we need to free the data, use the
4740 information stored by alloc_struct to find the beginning of the
4741 block allocated to the structure, so we can free it.
4743 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4745 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4748 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4749 (scm_debug_info): New member: id.
4751 * stacks.c: Stacks are now represented as structs; Stacks have an
4752 id given to them by `start-stack'.
4753 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4755 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4756 Changed stack representation.
4758 * debug.c (scm_procedure_name): Try procedure property `name' for
4759 compiled closures aswell.
4761 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4763 * eval.c: scm_i_name moved to gsubr.c
4764 (scm_m_define): Record names of all kinds of procedure
4765 objects. (Earlier, only closures were recorded.)
4767 * procprop.h: Added declaration of scm_i_name.
4769 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4770 (scm_make_gsubr): Record names of compiled closures.
4772 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4774 * debug.c, debug.h: Removed obsolete code.
4776 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4777 stacks.c: Renamed regs --> scm_contregs.
4779 * print.c (scm_free_print_state): Cleanup print state before
4780 returning it to pool. It is better to do it here than in
4781 scm_prin1 since scm_prin1 is called often.
4783 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4784 s_set_source_property_x): Check that first argument is a pair or a
4787 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4788 scm_i_line, scm_i_column and scm_i_breakpoint global.
4790 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4791 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4794 * debug.h: Added debug object smob declaration and macro
4797 * configure.in: Build with backtrace.o and stacks.o if debug
4800 * Makefile.in: Added entries for new files: backtrace.c,
4801 backtrace.h, stacks.c and stacks.h.
4803 * symbols.c (scm_sym2ovcell): Fixed documentation.
4805 * _scm.h (min, max): Added.
4807 * async.c: Moved `min' macro to _scm.h.
4809 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4810 SCM_BACKTRACE_INDENT.
4812 * eval.c: Added new debug options `maxdepth' and `indent'.
4814 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4816 * print.h: Added selector SCM_PRINT_STATE.
4818 * print.c: New functions: scm_make_print_state,
4819 scm_free_print_state.
4821 * print.h: Added declarations for scm_make_print_state,
4822 scm_free_print_state.
4824 * debug.c (scm_m_start_stack): New acro.
4826 * debug.h: Small cleanup.
4828 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4856 More prototype-related changes from Marius Vollmer:
4857 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4858 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4859 * ports.h (ptobfuns): Added prototypes. This means some casting in
4861 * fports.c: Added casts for initializations, since the functions
4862 are defined to take FILE * as their stream argument, not SCM.
4863 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4864 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4865 to `char *str_data' to conform to prototype.
4867 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4869 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4871 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4873 * stime.c, stime.h: use SCM_P method.
4875 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4877 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4878 be given at least two arguments. Insist that lst's last element
4879 be a list, but don't make any requirements of its predecessors.
4881 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4883 * eval.c (scm_nconc2last): Revert last change; there seems to be
4884 other stuff going on here.
4886 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4888 * eval.c (scm_nconc2last): Make sure that each element of lst
4889 (which is a list of argument lists, except for the tail) is a
4890 proper list, i.e., finite and terminated by '().
4892 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4894 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4897 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4898 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4901 * vectors.c (scm_make_vector): Fill vectors with the undefined
4902 value, to help make Guile Scheme code more portable to other
4905 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4906 * symbols.h, tags.h: Doc fixes.
4908 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4910 * async.c (scm_take_signal): Doc fixes.
4912 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4914 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4915 want to subtract it from the modulus; we just want to leave it
4918 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4920 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4923 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4925 * throw.c (scm_catch_apply): Finished implementation of
4928 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4930 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4932 (scm_init_filesys): set "i/o-extensions" feature.
4935 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4937 * Makefile.in (root.o): Correct dependencies.
4939 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4941 * Makefile.in: Added dependency entry for root.o.
4943 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4944 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4946 * init.c (scm_start_stack): Set initial root continuation number
4949 * procs.c: New function: scm_thunk_p.
4951 * procs.h: Added declarations of scm_thunk_p.
4953 * root.c: Renamed `call-with-new-root' -->
4954 `call-with-dynamic-root'.
4955 (cwdr): Removed allocation of new root state. This should be done
4956 separately by use of scm_make_root.
4957 (scm_apply_with_dynamic_root): New function: Does what it
4958 sounds like. Needed when spawning threads.
4960 * root.h: Added member last_debug_frame to root state.
4961 Added #include "libguile/debug.h"
4963 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4964 arguments. The motivation is that code in root.c needs catch
4965 functionality, and we want to avoid code duplication.
4966 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4967 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4968 handlers that run without popping the stack into the dynwind
4971 * throw.h: Added prototypes for scm_catch_apply and
4974 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4976 * root.h (scm_root, scm_set_root): Decouple thread support details
4977 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4978 SCM_SET_THREAD_LOCAL_DATA.
4980 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4981 and tortoise scanning loop.
4983 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4985 * Makefile.in: Rebuild dependencies.
4987 * libguile.h: #include "libguile/print.h" before "smob.h", since
4988 the latter uses the print_state structure.
4990 * throw.c (scm_ithrow): Use the correct variable when checking to
4991 see if a given element of scm_dynwinds is a valid catch.
4993 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4994 structure, abort; don't just silently ignore the garbage.
4996 * _scm.h: #include "print.h" here, since it seems to be used just
4998 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4999 strports.c, unif.h: Don't #include "print.h".
5001 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5003 * feature.h (scm_loc_features): Removed external declaration.
5004 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5006 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5008 * feature.c (scm_init_feature): Added threads feature (needs to be
5009 initialized here, since features doesn't exist when
5010 scm_init_threads is called).
5012 * libguile.h: Added #include "libguile/../threads/threads.h".
5013 (This is a kludge to get thread support working. This should be
5016 * configure.in, acconfig.h: Added flags for thread support.
5018 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5021 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5022 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5025 * _scm.h: Added conditional #include "threads.h"
5027 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5028 SCM_THREADS_SWITCHING_CODE.
5030 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5031 allocate the basic dynamic root object.
5032 (scm_boot_guile): Added call to scm_init_root.
5034 * root.c, root.h: Added root smob.
5035 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5036 functions: Implements dynamic roots mostly according to spec in
5037 SCM manual. Main difference is that the second argument is a
5038 throw handler rather than an error "thunk".
5040 * root.h: Added declaration of scm_init_root.
5042 * root.c: Added #include "genio.h", #include "smob.h", #include
5043 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5045 (scm_init_root): Added #include "root.x".
5047 * throw.c: Added #include "stackchk.h"
5048 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5049 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5050 can be used in scm_call_with_new_root; Added reenabling of stack
5051 checking when catching a throw.
5053 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5055 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5057 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5058 element is not found, as per R4RS.
5060 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5062 * list.c: Doc fixes throughout.
5064 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5066 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5067 declare the char * to be const. Avoids a warning in rgx.c.
5069 * ports.h: spelling fix.
5071 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5074 * load.c (scm_sys_try_load_path): throw an error if file not found
5075 (like it says it in NEWS).
5077 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5079 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5080 PROPS slot to '(), not #f; it's an empty alist.
5082 * throw.h, throw.c: Use SCM_P instead of #if hair.
5084 Remove special support for uncaught throws; see throw.c for
5086 * throw.c (uncaught_throw): New function.
5087 (scm_ithrow): Call uncaught_throw if we don't find a throw
5088 target; don't mess with scm_bad_throw_vcell.
5089 (scm_bad_throw_vcell): Variable deleted.
5090 (scm_init_throw): Don't initialize it.
5092 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5095 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5097 * numbers.c (scm_istr2int): If the number is short (as most
5098 numbers are), just call scm_small_istr2int to deal with it.
5099 (scm_small_istr2int): New function, created by un-#ifdefing the
5100 non-bignum version of scm_istr2int and renaming it.
5102 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5104 * load.c (scm_sys_try_load): don't check whether value returned
5105 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5106 Change the Scheme name from %try-load to primitive-load.
5108 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5109 Can avoid passing a message, allowing it to be derived in the
5110 error handler (e.g., if we want to throw to the key both from
5113 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5115 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5116 references now have a new appearance which is more compact and
5117 also gives a clue about what the target of the reference is.
5118 By setting parameters in the print state, more fancy printing can
5119 be achieved. This is used by the (not yet commited) backtrace
5122 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5124 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5127 * print.c: Added #include "struct.h". Removed function
5130 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5131 scm_iprin1. Removed prototype for scm_prlist.
5133 * arbiters.c (prinarb),
5134 async.c (print_async),
5135 debug.c (prindebugobj, prinmemoized),
5136 eval.c (prinprom, prinmacro),
5137 filesys.c (scm_fd_print, scm_dir_print),
5139 mallocs.c (prinmalloc),
5140 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5141 smob.h (scm_smobfuns),
5142 srcprop.c (prinsrcprops),
5144 unif.c, unif.h (scm_raprin1, rapr1),
5145 variable.c (prin_var): Changed argument `int writing' to
5146 `scm_print_state *pstate'.
5148 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5149 that it will be called before scm_init_print.
5151 * print.c (scm_prin1): Print states are now allocated when calling
5152 scm_prin1 and then passed around to all printing functions as an
5153 argument. A cache `print_state_pool' enables reuse of print
5155 (scm_make_print_state): New function.
5156 (scm_iprin1): Adaption to print states.
5157 (scm_iprlist): An initial "hare and tortoise" scan brings down
5158 time complexity to O (depth * N). (Better time complexity will be
5159 achieved when the printing code is completely rewritten.)
5161 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5163 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5164 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5165 it gets done whether or not the cache variable has a value.
5167 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5169 Distinguish #f and ().
5170 * __scm.h: #undef SICP.
5171 * pairs.h (SCM_EOL): Delete this definition, equating it with
5173 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5174 the value it used to have. Doc fixes, too.
5176 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5178 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5179 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5180 Lord's implementation of structs, allowing for tail arrays as
5181 described in the manual. Also fixed some bugs. (Both the interface
5182 and the implementation should be improved.)
5184 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5186 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5187 People who whish to see the source can do `(print-enable 'source)'.
5188 Removed #ifdef DEBUG_EXTENSIONS.
5190 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5192 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5193 integer (assuming for now accepting an integer is a good thing).
5195 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5196 %S will be used instead for write'ing arguments.
5198 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5199 asserts. fix a few other asserts.
5200 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5201 scm_uniform_vector_ref, scm_array_set_x,
5202 scm_dimensions_to_unform_array): change args in
5203 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5204 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5205 scm_substring_fill_x): likewise.
5206 gsubr.c (scm_gsubr_apply): likewise.
5207 eval.c (SCM_APPLY): likewise.
5209 * eval.c (4 places): replace scm_everr with lgh_error or
5212 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5213 scm_memory_error): new procedures.
5214 scm_everr: deleted. can use scm_wta, dropping first two args.
5215 scm_error: convert NULL subr to SCM_BOOL_F.
5217 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5220 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5223 * error.c, error.h: new error keys: scm_arg_type_key,
5224 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5226 scm_wta: reimplement using lgh_error instead of scm_everr.
5228 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5230 * gdbint.c: scm_lread now has one more argument.
5232 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5233 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5234 loading source from non-file ports, which, e. g., happens when
5235 using the Emacs interface).
5237 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5240 * read.c: Added code for recording of positions of source code
5241 expressions; New functions: recsexpr, scm_lreadrecparen;
5242 _scm_make_srcprops --> scm_make_srcprops
5243 (scm_flush_ws): Removed updating of positions counters. This work
5244 is already done by scm_gen_getc
5246 * read.h: Added prototype for scm_lreadrecparen
5248 * print.c: Added #include "alist.h"
5250 * eval.c: Added #include "hash.h"
5252 * eq.c: Added #include "ramap.h"
5254 * options.c: Documentation fixes.
5256 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5257 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5258 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5259 --> scm_make_srcprops
5261 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5262 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5263 function calls in the definition of the whash access macros.
5265 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5267 * init.c (scm_boot_guile): Add level of indirection to
5268 scm_boot_guile_1() to ensure that stack base pointer is properly
5269 initialized. There was no guarantee that variable i was the
5270 highest/lowest variable on stack (i.e. the call frame of
5271 scm_boot_guile was not completely protected from gc).
5273 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5275 * ports.h (scm_port_table): put back file_name, it will be used to
5276 support debugging. Undo related changes in fports.c, ioext.c,
5279 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5281 * ports.h (scm_port_table): remove file_name member for now, it seems
5283 * fports.c (scm_open_file): don't set file_name in PTAB.
5284 (prinfport): don't use file_name in PTAB.
5285 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5286 * ports.c (scm_add_to_port_table): don't intialize file_name.
5287 (scm_port_file_name): remove for now.
5288 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5290 * fports.h (scm_mkfile): prototype deleted.
5291 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5293 * debug.c, unif.c: use scm_out_of_range instead of
5294 wta for range errors (ASSERT still needs work).
5296 * error.c, error.h (scm_out_of_range): new procedure.
5298 * error.c, error.h (scm_out_of_range_key): new key.
5300 * posix.c (scm_sync): #else was missing.
5302 * error.c, error.h: append _key to names scm_num_overflow and
5305 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5306 of consing an empty list.
5307 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5308 of macros, saves code and string space.
5309 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5310 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5311 lower case. Rename scm_syserror_m to scm_syserror_msg.
5312 error.h: prototypes for new procedures.
5314 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5316 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5318 * error.c, error.h: setup scm_num_overflow key.
5320 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5321 Remove definition of SCM_OVSCM_FLOW.
5323 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5325 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5326 explicit message and args.
5328 * error.c, error.h, __scm.h: change system_error_sym to
5331 * error.c (system_error_sym): remove leading %% from the Scheme name
5334 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5336 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5338 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5339 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5340 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5341 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5342 renamed. (These were introduced by unsupervised name
5345 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5347 * print.c: Added code for detection of circular references during
5348 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5349 a hook for printing of closures (accessible via print options).
5350 This leads to a split of calls to scm_iprin1 into two classes:
5351 elementary print operations (e. g. the code which prints a smob)
5352 still use scm_iprin1 while top level calls (like scm_display) use
5353 scm_prin1. scm_prin1 begins by clearing the data structure used
5354 to record reference information.
5356 * print.h: Added declarations of scm_prin1 and scm_prlist.
5358 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5360 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5362 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5364 * error.c (err_head): scm_iprin1 --> scm_prin1
5366 * debug.c: Adjusted header comment.
5370 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5372 * strerror.c: Doc fix.
5374 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5376 * gdbint.c (gdb_read): Now possible to run during GC.
5377 (unmark_port, remark_port): New functions.
5379 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5381 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5382 of allocating a new string object. Also, increase size by
5383 the factor 2 instead of 1.5.
5385 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5387 * __scm.h (SCM_P): Corrected to run under traditional C.
5389 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5392 * async.c: Calls to scm_sysintern corrected.
5394 * async.h (scm_async_clock): Redundant declaration removed.
5396 * continuations.c (scm_dynthrow): Redundant declaration removed.
5398 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5399 Definition typos corrected.
5401 * debug.h: Missing declarations of functions in debug.c added
5404 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5405 Missing declarations to functions in eval.c added.
5407 * filesys.c: Possibly uninitialized variable rv.
5409 * gc.h (scm_object_addr, scm_unhash_name): Missing
5410 declarations of functions defined in gc.c added.
5412 * genio.c: Possible typos str_data -> wstr_data. ???
5414 * genio.c: Possibly unintended shadowing of local variable
5415 `int c' (gotos out of scope of inner `c'). ???
5417 * init.c: Uninitialized `SCM last' may be used.
5419 * ioext.h: (scm_sys_isatty_p): Typo.
5421 * list.h (scm_list_head): Missing prototype for function in
5424 * numbers.c (scm_two_doubles): Changed from extern to static
5425 (is used only within numbers.c).
5427 * numbers.h: Repeated declarations removed.
5429 * ports.h (scm_close_all_ports_except): Declaration for the
5430 function defined in ports.c added.
5432 * posix.h: Missing declarations added.
5434 * procs.h (scm_make_subr_opt): Missing declaration added.
5436 * socket.h (scm_sys_gethost): Missing declaration added.
5438 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5440 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5441 Missing declarations added.
5443 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5445 * struct.c: Uninitialized variable `SCM answer' may be used.
5447 * unif.c (l2ra): Declaration prototype.
5449 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5450 defined in ramap.c).
5452 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5453 Redundant declarations removed (they are in ramap.h).
5455 * variable.h (scm_make_udvariable,
5456 scm_make_undefined_variable): Declaration corrected to
5457 correspond variable.c.
5459 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5460 Missing declarations added.
5462 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5464 * Makefile.in (distclean): Don't forget to delete fd.h.
5466 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5468 * fd.h.in, tags.h: Trivial cleanups.
5470 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5471 marksweep.h just declared functions from gc.c.
5472 * gc.h, libguile.h: Don't #include "marksweep.h".
5473 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5474 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5475 dependencies updated.
5477 * libguile.h: Don't #include "files.h"; it's been deleted.
5479 * files.c (scm_sys_delete_file): Moved to filesys.c.
5480 File is now empty; deleted.
5482 * filesys.c: scm_sys_delete_file is now here. Remove
5483 #if's; they seem to rely on remnants of an old portability
5484 regimen. If the problems come up again, solve them properly,
5485 using autoconf. Specifically: Don't test M_SYSV, and #define
5486 remove to be unlink if it's #defined; don't use remove just
5487 because HAVE_STDC_HEADERS is #defined.
5488 * filesys.h: Add declarations for scm_sys_delete_file.
5489 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5490 files.o, files.h, files.c, and files.x.
5491 * init.c: Don't #include "files.h", and don't call scm_init_files.
5493 Use SCM_P instead of PROTO; the latter intrudes on the user's
5495 * params.h: Deleted; definition of SCM_P moved to...
5496 * __scm.h: ... here, where it replaces PROTO macro.
5497 * libguile.h, smob.h: Don't #include "params.h".
5498 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5499 smob.h: Fix prototypes accordingly.
5500 * Makefile.in: Update dependencies.
5501 (inner_h_files): Remove params.h.
5503 * gc.c: #include "gc.h"; every module should include its header,
5504 to let the compiler cross-check the declarations against the
5507 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5508 simpos.h: #include "libguile/__scm.h".
5510 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5512 * init.c: Don't forget to #include smob.h and init.h.
5513 * Makefile.in: Dependencies updated.
5515 * smob.h: Use PROTO instead of #if __STDC__.
5517 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5519 * __scm.h: Doc fixes.
5521 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5522 <angles>; this allows `make depends' to work properly.
5524 * libguile.h: #include smob.h and pairs.h before the others; they
5525 define typedefs used by other headers.
5527 C files should #include only the header files they need, not
5528 libguile.h (which #includes all the header files); the pointless
5529 recompilation was wasting my time.
5530 * Makefile.in (all .o dependency lists): Regenerated.
5531 * libguile.h: Don't try to get a definition for size_t here...
5532 * __scm.h: Do it here.
5533 * _scm.h: Since this is the internal libguile header, put things
5534 here that all (or a majority) of the libguile files will want.
5535 Don't #include <libguile.h> here; that generates dependencies on
5536 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5537 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5538 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5635 * weaks.c: Get "weaks.h".
5637 * stackchk.h: #include "libguile/debug.h",
5639 * print.h, read.h: #include "options.h", since everyone who uses
5640 either of these files will need that.
5642 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5643 anyone who uses this file will need them to define the smob
5644 printing functions. Also, get markers.h, since people will need
5645 to #define the mark functions.
5647 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5648 * ports.h: ... to here.
5650 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5651 don't rely on archaic C default type rules.
5653 * fports.h: #include "libguile/ports.h", since you need that in
5654 order to parse this.
5656 * genio.h: #include "libguile/print.h", because you need that to
5657 parse this; don't bother #including "ports.h", since print.h gets
5660 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5662 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5663 this; it's now a reference to an element of *scm_root.
5665 * debug.h: Don't #include "options.h"; the compiler won't be able
5666 to find that once the headers are installed; instead, #include
5667 "libguile/options.h".
5668 * gc.h: Same, with marksweep.h.
5669 * mbstrings.h: Same, with symbols.h.
5670 * scmhob.h: Same, with _scm.h.
5671 * smob.h: Same, with params.h.
5673 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5674 C files; there's no need for this, and it forces recompilations
5677 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5679 * error.c (scm_error): declare scm_error_callback.
5681 * error.h: prototype for scm_error_callback.
5683 * __scm.h: define lgh_error.
5684 (SCM_SYSERROR): redefine using lgh_error.
5686 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5688 * error.c (scm_error): new procedure.
5690 * error.h: prototype for scm_error.
5692 * Makefile.in (install): install scmconfig.h from the current
5693 directory, not $(srcdir).
5695 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5697 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5698 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5699 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5705 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5706 vports.h, weaks.h: #include "libguile/__scm.h", not
5707 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5708 dependencies are within libguile properly.
5710 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5712 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5713 when scmconfig.h doesn't exist.
5715 * load.c (scm_sys_try_load): Correct spelling.
5717 * feature.c (scm_loc_features): Make this static.
5719 * Makefile.in (libpath.h): Omit trailing slash from path. We
5720 shouldn't require it of users, so why put it here?
5722 Move code to initialize and search %load-path from ice-9 to C
5723 code, so we can use the load-path to find the ice-9 boot code;
5724 this makes it easier to run Guile without installing it. See
5725 corresponding changes in guile/Makefile.in.
5726 * feature.c: Move stuff concerned with the load path to load.c.
5727 (scm_compiled_library_path): Deleted.
5728 Don't #include libpath.h here.
5729 * feature.h: Don't mention scm_compiled_library_path.
5730 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5731 <sys/stat.h>, and <unistd.h> (if present).
5732 (R_OK): #define if the system hasn't deigned to.
5733 (scm_loc_load_path): New variable.
5734 (scm_init_load_path, scm_sys_search_load_path,
5735 scm_sys_try_load_path): New functions.
5736 (scm_init_load): Initialize scm_loc_load_path to point to the
5737 value cell of the Scheme %load-path variable.
5738 * load.h: Add declarations for scm_sys_search_load_path,
5739 scm_sys_try_load_path.
5740 * init.c: Call scm_init_load_path.
5741 * Makefile.in (feature.o, load.o): Dependencies updated.
5743 * load.c, load.h: Rewrite using PROTO macro.
5745 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5747 * gc.c (scm_cellp): New function: C predicate to determine if an
5748 SCM value can be regarded as a pointer to a cell on the heap.
5750 * gc.h: Added declaration of scm_cellp.
5752 * gdb_interface.h: New file: The GDB interface header from the GDB
5755 * gdbint.c: New file: GDB interface.
5757 * gdbint.h: New file: GDB interface.
5759 * libguile.h: Added #include <libguile/gdbint.h>.
5761 * init.c (scm_boot_guile): Added scm_init_gdbint.
5763 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5764 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5765 found if object files and source are kept separate).
5767 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5769 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5771 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5773 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5774 TK_SRC_DIR; they're not relevant any more.
5776 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5777 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5779 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5781 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5782 search path, so we can find the <libguile/MUMBLE.h> headers.
5784 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5786 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5787 implicit in the .c.o rule.
5788 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5791 Put the library path in a header file, instead of passing it on
5792 the command line in every compilation.
5793 * Makefile.in (libpath.h): New target.
5794 (feature.o): Depend on libpath.h.
5795 (clean): Delete libpath.h.
5796 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5797 * feature.c: ... #include "libpath.h" here.
5798 * .cvsignore: Ignore libpath.h.
5800 Don't install the unwashed masses of Guile header files in the
5801 main #include path; put most of them in a subdirectory called
5802 'libguile'. This avoids naming conflicts between Guile header
5803 files and system header files (of which there were a few).
5804 * Makefile.in (pkgincludedir): Deleted.
5805 (innerincludedir): New variable; this and $(includedir) are enough.
5806 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5807 (installed_h_files): Divide this up. Now this variable lists
5808 those header files which should go into $(includedir) (i.e. appear
5809 directly in the #include path), and ...
5810 (inner_h_files): ... this new variable says which files appear in
5811 a subdirectory, and are referred to as <libguile/mumble.h>.
5812 (h_files): List them both.
5813 (install): Create innerincludedir, not pkgincludedir. Put
5814 the installed_h_files and inner_h_files in their proper places.
5815 (uninstall): Corresponding changes.
5816 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5817 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5818 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5819 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5820 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5821 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5822 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5823 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5824 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5825 vports.h, weaks.h: Find __scm.h in its new location.
5826 * __scm.h: Find scmconfig.h and tags.h in their new locations
5827 (they're both "inner" files).
5829 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5831 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5833 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5835 * posix.c: Doc fixes.
5837 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5839 * socket.c: Don't include a prototype for inet_aton; just use a
5840 K&R style declaration, to avoid warnings but minimize the chance
5841 of conflicts with the system.
5843 On NextStep, <utime.h> doesn't define struct utime, unless we
5844 #define _POSIX_SOURCE before #including it.
5845 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5846 * acconfig.h: New comment text for above CPP symbol.
5847 * configure.in: Call it.
5848 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5850 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5852 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5853 testing for __EMX__.
5855 * posix.c: #include <libc.h>, if it exists.
5857 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5858 don't even know if the latter exists.
5860 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5861 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5862 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5864 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5866 (scm_init_posix): Use them when initializing the Scheme constants
5869 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5871 * Makefile.in (libdir, includedir, bindir): Use the
5872 autoconf-supplied values, instead of deriving them ourselves.
5873 (pkgincludedir, datadir, pkgdatadir): New variables.
5874 (install, uninstall): Put the header files in a special
5875 subdirectory, not in the main search path.
5877 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5878 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5880 * Makefile.in (IMPLPATH): Deleted; never used.
5882 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5883 on the Tcl/Tk source any more.
5884 (INCLUDE_CFLAGS): Remove references to the above.
5886 * Makefile.in (version.o): Corrected dependencies.
5888 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5890 * libguile.h: #include "version.h"
5892 * init.c (scm_boot_guile): Call scm_init_version.
5893 * gscm.c (gscm_run_scm): Call scm_init_version.
5895 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5896 GUILE_VERSION): AC_DEFINE these.
5897 (acconfig.h): #undef the above symbols.
5899 * Makefile.in (libobjs): Add version.o.
5900 (installed_h_files): Add version.h.
5901 (c_files): Add version.c.
5902 (gen_c_files): Add version.x.
5903 (version.o): New rule.
5904 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5905 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5906 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5907 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5908 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5909 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5910 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5911 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5912 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5913 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5914 weaks.o): Add version.h to dependency lists.
5915 (markers.o): Remove duplicate rule.
5917 * version.h: New file.
5919 * version.c: New file.
5921 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5923 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5924 array; use it appropriately. Since GCC is quite happy to
5925 subscript functions, it never warned us about this; we should use
5926 -Wpointer-arith in the future. I guess we never tested
5929 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5931 * socket.c: Doc and copyright fixes.
5933 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5935 * debug.c: Fixed and improved gdb support.
5937 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5939 * socket.c: Added declaration of inet_aton to avoid compiler
5940 warning. (Hope this solution is correct.)
5942 * stime.c: Added declaration of ftime. (This is missing in
5945 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5947 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5949 * Makefile.in (c_files): add strerror.c.
5951 * strerror.c: new file from Emacs' sysdep.c.
5952 maybe configure should also check for sys_errlist.
5954 * configure.in (AC_REPLACE_FUNCS): add strerror.
5956 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5958 * debug.c (scm_init_debug): Added initialization for
5959 scm_evaluator_traps.
5961 * debug.h, debug.c: Various name changes.
5962 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5963 "debug-options-interface". See commentary in options.c.
5965 * options.h, options.c: Options now have documentation strings.
5966 Also added a long explanatory commentary.
5968 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5971 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5972 last_debug_info_frame is now updated in all cases.
5974 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5977 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5979 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5980 Added option STACK_CHECKING.
5982 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5984 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5986 * __scm.h: Removed symbols for debugging support.
5988 * acconfig.h: Added symbols for debugging support.
5990 * configure.in: Added user option for debugging support.
5991 --enable-debug will include the debugging code into libguile.a.
5993 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5994 scm_relocate_chunk_to_heap.
5996 * debug.c: New file: low-level debugging support. It also
5997 includes support for debugging with gdb. (The extensions to gdb
5998 are written by Per Bothner at Cygnus.)
6000 * debug.h: New file: low-level debugging support.
6002 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6003 argument pairs. Extensive modifications to the debugging
6004 evaluator. Added "SECTION:" commentaries to clarify what happens
6005 when, during double compilation. Renamed EVALIMP --> EVALIM.
6006 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6007 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6008 the beginning of the file. New procedure: scm_unmemocopy.
6009 Added some global state variables needed by the debugging
6010 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6011 check_entry, check_apply, check_exit, debug_options and
6012 evaluator_traps. New acro: undefine.
6014 * eval.h: Renamed EVAL --> XEVAL.
6016 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6017 --> scm_make_weak_key_hash_table.
6019 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6020 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6022 * libguile.h: Conditionally include debug.h
6024 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6025 scm_object_properties shouldn't return handle. `handle' now gets
6026 initialized in scm_set_object_properties_x. scm_object_properties
6027 doesn't any longer create an entry in scm_object_whash.
6029 * options.c: New file: handling of run time options.
6031 * options.h: New file: handling of run time options.
6033 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6035 * print.c: New procedure: scm_print_options
6037 * print.h: Defines for print options.
6039 * read.c: New procedure: scm_read_options
6041 * read.h: Defines for reader options.
6043 * root.h: Added scm_source_whash among scm_sys_protects.
6045 * srcprop.c: New file: source properties.
6047 * srcprop.h: New file: source properties.
6049 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6050 (Bug found by A. Green.)
6052 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6054 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6056 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6058 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6060 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6061 and should be called by the final client.
6063 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6065 * gc.h: Use the PROTO macro when declaring functions.
6066 * gc.c: Use the PROTO macro when declaring static functions.
6067 Remove the CPP hair around function definitions.
6069 * gc.c (scm_init_storage): Initialize scm_asyncs.
6071 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6072 preprocessor symbol; "__scm.h" is where it might get #defined.
6073 * __scm.h: Similar: #include <scmconfig.h> before testing
6076 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6078 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6080 * init.c (scm_boot_guile): Add init_func argument; call
6081 (*init_func) instead of calling scm_appinit; it's ucky to
6082 hard-code names for the user's procedures.
6083 * init.h (scm_boot_guile): Adjust declaration.
6085 * __scm.h (PROTO): New macro, for declaring functions with
6088 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6089 eliminate all the __STDC__ conditionals.
6090 (scm_boot_guile): Add declaration.
6091 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6092 Remove __STDC__ conditionals around function definitions; the
6093 declarations in init.h will provide the same information, more
6096 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6097 complain about it in the error message; the error message is
6098 adequate without that note, and there's nothing the user can do
6101 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6103 * Makefile.in (ancillary): Drop def.sed.
6105 * posix.c (scm_init_posix): Use numeric values, rather than
6106 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6107 F_OK. The symbols aren't available on some systems, and I'm
6108 pretty sure their values are fixed by common widespread practice.
6109 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6111 More functions unavailable on some systems.
6112 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6113 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6115 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6116 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6117 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6118 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6119 stub that signals an error as the #else.
6121 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6123 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6125 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6127 * unif.c: include ramap.h.
6129 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6131 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6133 * ports.c: include sys/ioctl.h.
6135 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6137 * configure.in: check for sys/ioctl.h.
6139 * ports.c: include <malloc.h> not "malloc.h".
6141 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6143 * fports.c: remove ttyname and tmpnam declarations.
6145 * posix.c: fewer ttyname declarations.
6147 * fports.c: include <string.h> not "string.h".
6149 * init.c, ioext.c: include string.h and unistd.h.
6151 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6153 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6154 genio.c, simpos.c, vports.c: include string.h.
6156 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6158 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6160 (scm_addr_buffer_size): change type from scm_sizet to int.
6161 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6162 from scm_sizet to int.
6164 * error.c: include unistd.h.
6166 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6169 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6171 * __scm.hd, def.sed: deleted.
6173 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6175 Changes for NeXT, suggested by Robert Brown.
6176 * configure.in: Call AC_TYPE_MODE_T.
6177 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6178 NeXT. Put header file list in alphabetical order.
6179 * configure, scmconfig.h.in: Regenerated.
6180 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6182 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6185 * acconfig.h: New file, providing documentation for the CPP
6186 symbols defined in configure.in
6187 * acconfig-1.5.h: Removed; superceded by the above.
6189 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6191 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6193 * fports.c (scm_open_file): don't return #f, throw error.
6195 * ioext.c (fileno): renamed from %fileno.
6196 (soft-fileno): deleted.
6198 * ports.c (scm_port_revealed): don't need to check for -1 from
6200 (scm_set_port_revealed_x): return unspecified, not #f.
6202 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6204 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6206 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6208 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6210 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6212 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6213 This is necessary on Ultrix, and doesn't hurt portability.
6215 * Makefile.in (dist-dir): New target, implementing a new dist system.
6216 (installed_h_files): Put in alphabetical order.
6217 Remove duplicate entries for markers.h and unif.h.
6218 (c_files): Remove duplicate entries for markers.c.
6219 (ancillary): Renamed from anillery; all uses changed. Remove
6220 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6221 Remove all the ../doc/* files; doc/Makefile.in handles that.
6223 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6225 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6226 every if must have an else, or else the whole command has a
6227 non-zero exit code whenever the if's condition is false.
6229 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6231 * posix.c: include string.h.
6233 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6235 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6238 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6239 Remove leading % from scheme names.
6240 Do not return error values, call SCM_SYSERROR or similar.
6242 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6244 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6246 * struct.c (scm_init_struct): new file.
6248 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6250 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.

6486 initialization to fix a race condition.
6488 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6515 The weird symbol syntax is also a bit bogus (emacs doesn't quite
