1 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * modules.c, modules.h: New files: C interface to modules. (This
4 is necessary in order to interface the object system to Guile
5 properly. The guts of these modules will be replaced by the new
6 module system in the future.)
8 * init.c: Added #include "modules.h"
9 (scm_boot_guile_1): Call scm_init_modules.
10 (invoke_main_func): Call scm_post_boot_init_modules.
12 * Makefile.am: Added modules.c, modules.x, modules.h.
14 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
16 * procs.c: #include "objects.h"
17 (scm_procedure_p): Return #t also on structs which are operators.
19 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
20 <operator-metaclass> and <entity-class> to <standard-class>,
21 <operator-class> and <entity> in order to conform with STKlos
24 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
25 which isn't an operator.
26 (SCM_APPLY): Ditto, but jump to badproc.
28 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
30 * eval.c (SCM_CEVAL): Allow structs implanted in code.
31 Previously, structs implanted in code were interpreted as forms
32 the operator of which was a gloc. We solve this by checking for
33 the zero in the emulated vcell in the struct vtable. Since
34 implanted structs always will look like forms with a gloc
35 operator, execution will only be slowed down by maximally one
36 extra test-and-branch per application.
38 * evalext.c (scm_definedp): Removed check for isyms; Added a
39 second optional argument: It is now possible to supply an
40 evaluation environment in which to look for the symbol.
42 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
44 * readline.c (scm_init_readline): Set
45 rl_basic_word_break_characters. (Thanks to Ian Grant.)
47 * coop.c (coop_condition_variable_wait): Removed
48 (coop_condition_variable_wait_mutex): Folded logic of
49 coop_mutex_unlock into coop_condition_variable_wait_mutex to
50 prevent condvar signal lossage. Previously, another thread could
51 start to run after unlocking the mutex but before putting the
52 current thread on the wait queue. If that thread then would
53 signal the first, the signal would be lost. (Thanks to Christian
56 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
58 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
61 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
63 * objects.c (scm_i_make_class_object): Renamed from
64 make_class_object; exported; error checking moved to
65 scm_make_class_object and scm_make_subclass_object.
66 (scm_make_class_object, scm_make_subclass_object): Use
67 scm_i_make_class_object.
68 (scm_make_subclass_object): Let the subclass have same metaclass
71 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
73 * debug.c (scm_debug_options): Bugfix: Set the value of
74 scm_stack_checking_enabled_p after setting debug options;
75 #include "stackchk.h". (Thanks to Richard Polton.)
77 1998-11-13 Radey Shouman <rshouman@metro2000.com>
79 * unif.c (scm_array_contents): removed unnecessary test for 0
82 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
84 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
85 Replaced by macro `collect' in boot-9.scm.
87 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
89 * eval.c (scm_copy_tree): Copy source properties if existent.
91 * debug.c (scm_start_stack): Copy source when evaluating. (If we
92 don't, we may end up passing memoized source to a transformer.)
94 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
96 * stack.c (get_applybody): Help function which lookups the first
97 body form of the apply closure.
98 (read_frames): Prevent the source of the first form of the apply
99 closure from being recorded. This would only be confusing.
101 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
102 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
104 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
106 * stacks.c (read_frame): Bugfix: Removed lingering `else'
108 (read_frames): Use SCM_MACROEXPP.
110 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
112 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
113 don't contain interesting information since all arguments are
114 present in the frame which applies the compiled closure anyway.);
115 Skip the transformer application frames.
117 * print.c (scm_iprin1): Print gsubrs as primitives.
119 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
121 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
123 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
124 that we can identify these in a backtrace. (This change doesn't
125 introduce any significant speed penalty.)
127 * eval.c: Added note about `serial-map' using scm_map.
129 * read.c, read.h (scm_read_options, scm_read_opts): Removed
130 readline options. They should reside in their own options array.
132 * readline.c, readline.h (scm_readline_options,
133 scm_readline_opts): Moved readline options here.
135 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
137 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
138 SCM_ROCHARS instead of SCM_CHARS.
140 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
141 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
143 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
145 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
146 This is quite important since the latter clears the
147 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
148 every single character read...
150 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
152 * print.c (scm_iprin1): Removed suspect looking (and indeed
153 malevolent) semicolon after test for user supplied closure print
154 procedure. (Thanks to Telford Tendys.)
156 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
157 (scm_memq, scm_memv, scm_member): Do argument checking *before*
158 starting to search the list. Removed call to sloppy_mem_check.
160 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
161 procedures: Same as scm_delq_x et al, but delete maximally one
164 * options.c (scm_options, scm_init_options): GC-protect option
165 values of type SCM. (Thanks to Telford Tendys.)
167 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
169 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
170 make sure that there always is a "real" scm_lookupcar.
172 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
174 * read.c, read.h (history-length, history-file): New read options.
175 (scm_read_options): Stifle history to history length.
177 * readline.c (scm_read_history, scm_write_history): New
180 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
182 * eval.h (scm_macro_eval_x): Removed declaration.
184 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
185 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
186 Renamed and made global.
188 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
189 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
191 * evalext.c, evalext.h: New files. Contain non-R5RS things
192 having to do with evaluation.
194 * evalext.c (scm_serial_map): New procedure: Version of `map'
195 which guarantees that the procedure is applied to the lists in
197 (scm_m_sequence_to_list): New syntax: Version of `begin' which
198 returns a list of the results of the body forms instead of the
199 result of the last body form.
200 (scm_definedp, scm_m_undefine): Moved from eval.c
202 * evalext.h (scm_m_sequence_to_list): Added declaration.
204 * macros.c, macros.h: New files.
205 (scm_procedure_to_syntax, scm_procedure_to_macro,
206 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
207 scm_macro_name, scm_macro_transformer): Moved from eval.c
208 (scm_make_synt): Moved from eval.c
210 * procs.c, procs.h (scm_procedure_documentation): Moved from
213 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
216 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
218 * debug.c, print.c: Added #include "macros.h".
220 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
222 This change adds the ability to use `unread-char' multiple times
223 without interspersed reads and adds the new procedure
224 `unread-string'. The change is optimized for the common case of
225 unreading a single character. This is also the reason behind the
226 choice to store characters in the port itself: in most cases no
227 extra malloc is required.
229 The amount of code in some macros in ports.h has been increased to
230 the extent that they would fit better as C functions, but, since
231 this code belongs to the port representation, such functions
232 should be placed in ports.c which would cause calls back and forth
233 between ports.c and genio.c. That is not good for performance.
234 Also, keeping them as macros allows the compiler to do some
235 optimizations which are needed to make the current interface
236 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
238 One benchmark (Guile startup time) indicates an increase of
239 loading speed of 1%. Another (reading (using `read') boot-9.scm
240 10 times) shows no change in performance.
242 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
243 made to find a beautiful solution.)
245 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
246 (SCM_TRY_CLRDY): New macro: Only clear the first unread
247 character. (SCM_CLRDY clears all.)
248 (SCM_N_READY_CHARS): New macro: Returns number of unread
249 characters in a port. Returns wrong answer if SCM_CRDYP is false.
250 (struct scm_port_table): New fields: `entry' contains port table
251 index, `cp' points to last unread char, `cbuf' is the buffer for
252 unread chars, `cbufend' points after end of the character buffer.
254 * ports.h, ports.c (scm_unread_string): New procedure.
255 (scm_grow_port_cbuf): New function.
257 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
259 (scm_generic_fgets), fports.c (local_fgets): Use a loop
260 to read unread characters. Use SCM_TRY_CLRDY instead of
263 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
265 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
267 * genio.c, genio.h (scm_ungets): New function.
269 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
272 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
274 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
275 declarations. (Thanks to Russ McManus.)
277 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
279 * numbers.c (num2long): As a software archeologist, I'm proud of
280 this finding! :) Preliminary dating suggests an almost 4 year old
281 remnant from the SCM ancestor. The sample has been removed from
282 the finding site and is now safely stored in the repository.
284 * numbers.h: Removed prototype for num2long.
286 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
288 * gh_data.c (gh_scm2doubles): Make it possible to pass result
290 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
291 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
292 * gh.h: Updated and added prototypes.
294 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
296 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
298 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
300 * guile-snarf.in: Never generate an empty file. (Thanks to
303 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
304 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
305 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
306 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
307 gh_new_procedure5_0): Specify argument types, to appease C++
308 compilers. (Thanks to Brad Bowman.)
310 Bug reports from Russ McManus:
311 * guile-snarf.in: If the CPP environment variable is set, use that
312 as the C preprocessor, instead of the preprocessor autoconf
314 * snarf.h (SCM_PROC): Cast the function pointer passed to
315 scm_make_gsubr, to satisfy C++.
317 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
318 Use the handler passed, instead of ignoring it and using
319 gh_standard_handler. (Thanks to Etienne Bernard.)
321 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
323 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

346 * script.c (scm_compile_shell_switches): Define
347 use-emacs-interface in the root module, so the repl code can see
348 it. See today's change to top-repl in ice-9/boot-9.scm.
350 * filesys.c (set_element, get_element): Make sure that `element'
351 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
352 Boekemeier and Jorgen "forcer" Schaefer.)
354 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
356 * chars.c (scm_charnames): In ASCII character name table, make
357 newlines print as #\newline by default, not #\nl.
359 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
360 alphabetical order. Oh thrills. But it helps me know how far
361 along in the compilation I am.
362 * Makefile.in: Regenerated.
364 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
366 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
367 #bytes(...) to #y(...), and syntax for short vectors from
368 #short(...) to #h(...). This may seem nutty, but, like the other
369 uniform vectors, byte vectors and short vectors want to have the
370 same print and read syntax (and, more basic, want to have read
371 syntax!). Changing the read syntax to use multiple characters
372 after the hash sign breaks with the conventions used in R5RS and
373 the conventions used for the other uniform vectors. It also
374 introduces complexity in the current reader, both on the C and
375 Scheme levels. (The Right solution is probably to change the
376 syntax and prototypes for uniform vectors entirely.)
378 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
380 Don't use local_fgets on sockets; ftell doesn't work on sockets.
381 (Thanks to Jorgen "forcer" Schaefer.)
382 * ports.h (SCM_NOFTELL): New flag.
383 * fports.c (local_fgets): If it's set, use the generic fgets.
384 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
386 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
388 * script.c (scm_compile_shell_switches): Add handling of -q switch
389 (inhibit loading of user init file).
390 (scm_shell_usage): Add usage text for -q switch.
391 (scm_compile_shell_switches): Always load user init file first if
394 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
396 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
397 and is now broken under NetBSD. I can't fathom what it's trying
398 to do, so I've replaced it with something that I do understand,
399 which seems to work, and which isn't broken on NetBSD. "Progress?
400 You Decide." (Thanks to Perry Metzger.)
402 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
403 signed/unsigned comparison.
405 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
407 Warning fixes from Greg Harvey:
408 * unif.c (scm_array_set_x): initializer for pos
409 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
410 * struct.c (scm_struct_ref, scm_struct_set_x): Added
411 initializers for field_type, since EGCS so desparately wants to
413 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
414 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
415 when GUILE_DEBUG is defined.
416 * dynwind.h (scm_wind_chain): Same.
417 * ports.h (scm_pt_size, scm_pt_member): Same.
418 * print.h (scm_current_pstate): Same.
419 * procs.h (scm_make_cclo): Same.
421 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
423 Handle short and long long uniform arrays properly. (Thanks to
425 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
426 raeql_1): Add cases for scm_tc7_svect (short vectors) and
427 scm_tc7_llvect (long long vectors).
429 Change the way libguile and boot-9.scm are timestamped, to try to
430 get rid of these spurious mismatch warnings. Now both
431 libguile/versiondat.h and ice-9/version.scm are generated directly
432 by the configuration process, rather than having version.scm
433 generated directly, and libguile/versiondat.h generated by the
434 Makefile, which is generated by configure. It seems that
435 sometimes the Makefile would change, but versiondat.h depends on
436 Makefile.in, not Makefile, so it wouldn't get rebuilt.
437 * Makefile.am (versiondat.h): Target removed; this is generated
438 directly by the configure script now.
439 (BUILT_SOURCES): Remove versiondat.h.
440 * versiondat.h.in: New file, transformed by the configure script
442 * Makefile.in: Regenerated.
444 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
445 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
446 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
447 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
448 if we want to use them in a header file some day, we can. (Thanks
451 * stime.c (scm_get_internal_real_time): Do the arithmetic using
452 SCM numbers, so we won't have rollover problems; the range of a
453 signed long in milliseconds is about 25 days. (Thanks to Karl
456 Don't redefine sleep and usleep; fix this problem now.
457 * coop.c (sleep, usleep): Remove declarations; we don't use or
458 redefine these any more.
459 (scm_thread_usleep, scm_thread_sleep): New functions which do the
460 job of usleep and sleep in a thread-friendly way. We can use
461 these in the rest of Guile. Define versions for systems both with
463 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
464 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
465 we're just using it, not redefining it, we can use a K&R style
467 (sleep): Declare this, too, if the system hasn't.
468 (scm_sleep, scm_usleep): Use scm_thread_sleep and
469 scm_uthread_sleep if they're available; otherwise, just call the
471 * scmconfig.h.in: Regenerated.
473 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
475 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
477 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
479 * threads.c: Doc fix.
481 The argument type of usleep varies from system to system,
482 as does the return type. We really shouldn't be redefining usleep
483 at all, but I don't have time to clean that up before the 1.3.
484 release. It's on the schedule for afterwards. (Thanks to Julian
486 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
488 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
489 * scmconfig.h: Regenerated.
491 * simpos.c (scm_software_type): Procedure deleted. This isn't the
492 right way to handle system variation. Autoconf's approach is the
494 * simpos.h (scm_software_type): Declaration deleted.
496 * script.c (scm_find_executable): Don't test if unix is #defined
497 here; first, NetBSD doesn't #define it, and second, it's the wrong
498 way to go about these things. (Thanks to Perry Metzger.)
499 (dld_find_executable): Delete this MSDOS support code. This isn't
500 the way we want to support this; it needs to be rethunk at a
503 * genio.c (scm_do_read_line): Don't just politely check that the
504 line was either non-empty or EOF. Abort if it's empty and not

509 * scmconfig.h.in: Regenerated.
511 * libguile.h: Don't omit the dynamic linking functions. (Thanks
514 * genio.c (scm_do_read_line): Count lines correctly when the file
515 doesn't end in a newline.
517 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
519 * genio.c (scm_do_read_line): Maintain the line count correctly.
520 (Thanks to Harvey J. Stein and Greg Harvey.)
522 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
525 * numbers.c (big2str): Protect t from garbage collection until
526 we're done. (Thanks to Gary Houston.)
528 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
530 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
532 * Makefile.in: Regenerated.
534 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
535 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
538 Do magic to mix reads and writes on stdio FILE-based ports.
539 (Thanks to Christian Lynbech.)
540 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
542 (pre_read, pre_write): New functions.
543 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
544 local_fputs): Call them.
545 (local_fflush): Mark the port as ready for reading and writing.
546 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
547 flags on new port objects. This might not be accurate --- who
548 knows what state the FILE * is in when we get it --- but it won't
549 do extraneous calls to fflush or fseek, so it's no worse than the
550 behavior before this change.
551 * ports.h: Add comment.
553 Centralize the creation of port objects based on stdio FILE * in
554 fports.c; don't just throw them together anywhere.
555 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
556 what the rest of Guile wants. Don't set the revealed count;
557 that's only appropriate for stdin, stdout, stderr.
558 (scm_standard_stream_to_port): This function does set the revealed
560 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
561 not scm_stdio_to_port.
562 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
563 * fports.c (scm_open_file): Same.
564 * posix.c (scm_pipe): Same.
565 * socket.c (scm_sock_fd_to_port): Same.
566 * ioext.c (scm_fdopen): Same.
567 (scm_freopen): Moved from here to...
568 * fports.c (scm_freopen): ... here. This is really something that
569 munges the internals of an fport, so it should go here.
570 * fports.h (scm_stdio_to_port): Adjust prototype.
571 (scm_standard_stream_to_port, scm_freopen): New protoypes.
572 * ioext.h (scm_freopen): Prototype removed.
574 * filesys.c (set_element, get_element): This can work on both pipe
575 and file ports, so use SCM_FPORTP to typecheck, instead of testing
578 * scmconfig.h.in: Regenerated.
580 Change the definition of the functions in scm_ptobfuns so that
581 they get passed the port object, not the port's stream.
582 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
583 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
584 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
585 Pass the port itself to the scm_ptobs function.
586 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
587 scm_generic_fgets): Same.
588 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
589 getc_void_port, fgets_void_port, close_void_port): Just change the
590 argument names; these functions don't really do anything.
591 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
592 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
593 port as an argument, and use SCM_STREAM to get the stdio FILE *.
594 Also, use prototyped definitions, and get rid of the extra
596 (scm_fptob, scm_pipob): We don't need casts here any more.
597 * strports.c (prinstpt): Use prototype declarations.
598 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
599 and use SCM_STREAM to get the string info. Also, use prototyped
600 definitions, and get rid of the extra declarations.
601 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
604 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
605 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
607 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
608 scm_fgets, for consistency.
609 (scm_fptop, scm_pipob): References updated.
611 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
613 Include the source location in error messages for scripts.
614 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
615 stack is still there when we catch the error.
616 * throw.c (handler_message): If we are handling an error with a
617 message, then put together the proper arguments and call
618 scm_display_error, instead of scm_display_error_message. That
619 displays source location, if it can find it.
621 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
623 * gc.c (scm_unprotect_object): Change this so that calls to
624 scm_protect_object and scm_unprotect_object nest properly.
625 (scm_protect_object): Doc fixes.
627 * strings.c (scm_string_set_x): Require the argument to be a
628 writable string, not a substring or a symbol.
629 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
630 (Thanks to John Redford and Charbel Jacquin.)
632 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
634 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
636 * eval.c (safe_setjmp): Remove this misunderstanding.
637 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
640 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
642 * libguile.h: Mark these as C declarations, for compilation by C++
645 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
646 __cplusplus clause. I seriously doubt this ever worked the way
647 the author seems to have intended.
649 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
651 Utterly needless cleanups to hopelessly messy code.
652 * ports.c: Doc fixes.
653 (scm_fflush): Moved to ...
654 * genio.c (scm_fflush): ... here, amongst all the other port
655 method invocation functions.
656 * genio.h, ports.h: The prototype moves too.
658 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
660 * backtrace.c (display_error_body): The current frame does not
661 always have a parent frame; consider a function called directly
662 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
665 * alloca.c (alloca): Undo yesterday's changes, and simply call
666 malloc directly for storage, and abort if we don't get what we
667 want. The situation is much simpler --- just call malloc. Emacs
668 has bizarre/evil requirements (signal handlers might malloc unless
669 you set this global flag, so you have to set the flag around all
670 calls to malloc) which we are certainly not going to conform to,
671 so we can do the simple and obvious thing.
673 * coop.c (coop_condition_variable_wait): Make this function
674 static. It's only useful internally --- you should never just
675 wait on a condition variable.
676 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
678 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
680 * unif.c (scm_array_set_x): Accept any kind of number as an
681 element for a uniform vector of doubles. This is more consistent
682 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
684 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
685 works; I can't conveniently test it myself. (Thanks to Dvid
686 Tillman for the bug report.)
690 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
691 from here, not from scm_compile_shell_switches (which is a pretty
692 dumb place to do it).
693 (scm_load_startup_files): New function.
694 (scm_ice_9_already_loaded): Variable moved to here from script.c.
695 * script.c (scm_compile_shell_switches): Don't load the startup
697 (scm_ice_9_already_loaded): Variable moved.
698 * init.c (scm_load_startup_files): Prototype for new function.
699 * gh_init.c (gh_enter): Doc fix.
701 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
703 Some anti-warning changes from Greg Harvey.
704 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
705 warnings when it doesn't understand our NORETURN declarations in
707 * posix.c (scm_mknod): Similar.
709 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
711 * posix.c (scm_getpwuid): If we can't find an entry, return our
712 own message, instead of using scm_syserror --- the getpwMUMBLE
713 functions don't set `errno' to anything interesting.
715 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
717 Get rid of warnings from the cooperative threading system.
718 * threads.h (scm_single_thread_p, scm_yield,
719 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
720 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
721 scm_wait_condition_variable, scm_signal_condition_variable): Add
722 prototypes for these Scheme-visible functions.
723 * coop-defs.h (coop_next_runnable_thread,
724 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
725 Prototypes for these here, even though they're from iselect.c.
726 (coop_condition_variable_wait, coop_join): Add prototypes.
727 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
728 scm_threads_free_condvar): Make these smob functions static.
729 * coop-threads.h (coop_init): Give this a real prototype.
730 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
731 (coop_next_runnable_thread): No need to provide prototype; it's in
734 * scmconfig.h.in: .detarenegeR
736 * iselect.c, threads.c: Doc fixes.
738 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
740 * Makefile.in: Regenerated with a patched automake, to get
741 dependency generation right when using EGCS.
743 * inet_aton.c (inet_aton): Add prototype, to remove compiler
744 warning. (Thanks to Robert Pluim.)
746 * inet_aton.c (inet_aton): Reassure the compiler that the
747 arguments to the <ctype.h> macros are all unsigned characters, not
750 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
752 Getting rid of more warnings...
753 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
754 today's change to ../configure.in.
755 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
756 * scmconfig.h.in: Regenertaded.de.,.__
757 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
758 (scm_localtime, scm_mktime): Use a const char * to manipulate the
761 * readline.c: Doc fix.
762 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
763 * readline.h (scm_filename_completion_function): Add prototype.
764 (scm_init_readline): Make this into a prototype.
766 * readline.c (scm_filename_completion_function): Use SCM_PROC to
767 declare this, instead of calling scm_make_subr manually.
769 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
771 * readline.h (scm_init_readline): Add prototype for this.
772 (scm_init_readline): Make this a real prototype.
774 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
776 Warning fixes from Maciej Stachowiak:
777 * backtrace.h (scm_display_application, scm_backtrace): Add
779 * debug.c (scm_m_start_stack): Make this function static.
780 * fluids.h (scm_fluid_p): Add prototype.
781 * procprop.c (scm_i_procedure_arity): Make this function static.
782 * regex-posix.c (scm_regexp_error_msg): Make this function static.
783 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
784 * root.h (scm_dynamic_root): Add external prototype.
785 * scmsigs.h (scm_usleep): Add external prototype.
786 * script.h (scm_init_script): Use prototype, not K&R decl.
787 * stacks.h (scm_stack_id): Add external prototype.
788 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
790 1998-09-30 Mark Galassi <rosalia@cygnus.com>
792 * gh.h: took out the definitions of vset and vref, since they are
793 replaced by the proper vector routines that correspond to the R4RS
796 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
798 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
799 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
800 third argument, a C expression that should result in a SCM value,
801 which is used to initialize the variable. Reimplemented
802 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
805 * version.h (scm_libguile_config_stamp): Add prototype.
806 (From Maciej Stachowiak.)
808 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
810 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
811 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
813 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
815 * print.c (scm_iprin1): Rather than having one i, and using it in
816 several places, declare a fresh i local to each block where it is
817 used, and give it a signedness appropriate to its use in each case.
820 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
823 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
824 signed/unsigned clashes.
826 * posix.h (scm_tmpnam): Added prototype.
828 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
829 scm_make_subclass_object): Add external prototypes.
831 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
832 comparison is okay here.
834 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
836 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
837 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
839 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
842 * load.c (swap_port): Make this function static.
844 * load.c (scm_search_path): Make max_path_len and max_ext_len
845 unsigned, since they're compared against string sizes.
847 * load.c (init_build_info): Make i unsigned.
849 * ioext.h (scm_read_line): Add prototype.
851 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
852 scm_hash_fn_remove_x): Make hash bucket index local variable k
853 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
854 accurately as possible.
856 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
857 comparisons, and range checking to make sure those casts are
860 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
861 signed/unsigned comparisons.
863 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
864 avoid signed/unsigned comparisons.
865 * smob.h (scm_numsmob): Change extern declaration to match.
867 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
868 avoid signed/unsigned comparisons.
869 * ports.h (scm_numptob): Change extern declaration to match.
870 (scm_current_load_port, scm_set_port_line_x,
871 scm_set_port_column_x): New prototypes.
873 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
874 test code, and it causes warnings.
876 * gh.h (gh_int2scmb, gh_uniform_vector_length,
877 gh_uniform_vector_ref): Added prototypes.
879 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
880 debugging support unconditionally. That's backtrace.c, stack.c,
881 debug.c, and srcprop.c.
882 (EXTRA_libguile_la_SOURCES): Omit those from here.
883 * Makefile.in: Regenerated.
885 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
887 * options.c (scm_options): Bugfix: Allow empty list of options!
889 * debug.c, debug.h (scm_single_step): Removed.
890 (scm_with_traps): New procedure. This procedure could easily be
891 written in Scheme but needs to be highly optimized.
893 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
895 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
896 Check SCM_TRAPS_P before trapping.
898 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
900 Changes to avoid signed/unsigned comparison warnings.
901 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
902 (scm_gc_sweep): Make n and j local to the blocks they're used in,
903 so they can have appropriate types for each application. Make i
904 signed. Use initializers in some spots. I'll probably pay for
906 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
907 (scm_must_realloc): Make nm unsigned.
908 (init_heap_seg): Make new_seg_index and n_new_objects signed.
909 (scm_init_storage): Use prototype-style definition, and make the
911 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
912 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
914 * filesys.c (scm_readlink): Make local vars rv and size ints, to
915 avoid signed/unsigned comparison warnings, and because the return
916 value of readlink may be -1. Don't bother casting the third
917 argument to readlink.
919 * filesys.c (scm_dirname, scm_basename): Move these to their own
920 page, at the end of the file.
921 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
923 * eval.h (scm_eval_options_interface): Add external prototype for this.
924 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
926 * eval.c (scm_lookupcar1): Make this static.
928 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
929 Make these prototype declarations, not K&R-style.
931 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
932 unsigned comparison warning.
934 * appinit.c: File removed. It had a single function in it, empty,
935 whose reason for existence is explained in no documentation or
936 comment. I think it's there as a default for some Tcl-style
937 initialization, but Tcl abandoned that approach a while ago.
938 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
939 (BUILT_SOURCES): Remove appinit.x.
940 * Makefile.in: Regenerated.
942 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
944 * Makefile.in: Regenerated using the last public version of
945 automake, not the hacked Cygnus version.
947 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
949 Remove Totoro kludge.
950 * Makefile.in, scmconfig.h.in: Regenerated.
951 * init.c, readline.c: Don't check if TOTORO is #defined.
953 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
955 * Makefile.am: Adjust for new thread configuration system.
956 (INCLUDES): Include the value of THREAD_CPPFLAGS.
957 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
959 (THREAD_LIBS): Definition deleted; automake will generate such
960 things automatically.
961 * Makefile.in: Regenerated.
963 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
965 Simplify smob and port marking; set the mark bit in the generic
966 marking code, and make marker routines only responsible for
967 turning up outgoing pointers.
968 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
969 before calling the marking function. Don't call the marking
970 function if it's zero.
971 * markers.c (scm_mark0): Just return #f. This function isn't
972 necessary at all now, but it's harmless to call it. We'll leave
973 it in so other folks' code doesn't croak at link time.
974 (scm_markcdr): Don't call SCM_SETGC8MARK.
975 * async.c (mark_async): Don't call SCM_SETGC8MARK.
976 * dynl.c (mark_dynl_obj): Same.
977 * root.c (mark_root): Same.
978 * srcprop.c (marksrcprops): Same.
979 * unif.c (markra): Same.
980 * variable.c (scm_markvar): Same.
981 * ports.c (scm_markstream): Same.
982 (void_port_ptob): Specify zero for our marking function.
983 * debug.c (debugobjsmob): Same.
984 * dynwind.c (guardsmob): Same.
985 * filesys.c (dir_smob): Same.
986 * fluids.c (fluid_smob): Same.
987 * fports.c (scm_fptob, scm_pipob): Same.
988 * mallocs.c (mallocsmob): Same.
989 * regex-posix.c (regex_t_smob): Same.
990 * smob.c (freecell, flob, bigob): Same.
991 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
992 * throw.c (jbsmob, lazy_catch_funs): Same.
994 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
996 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
997 scm_copy_tree on code in order not to let memoized code to leak
998 out. Thus, scm_copy_tree needs to copy vectors as well since
999 quasiquote can introduce evaluated code also inside vector
1002 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1004 * eval.c (scm_copy_tree): Removed ability to copy vectors.
1006 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
1007 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
1010 * unif.c: Say that ivect and uvect are of type signed and unsigned
1011 long instead of int in commentary so that it correctly describes
1014 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1016 * stime.c: Removed declaration of strptime. (It should be
1017 declared by the system headers. If it turns out that some systems
1018 don't, we'll handle that then.) (Thanks to Greg Troxel.)
1020 * stime.h: Renamed TIMEH --> STIMEH
1022 * backtrace.c (scm_display_error, scm_display_backtrace): In order
1023 to increase portability, don't use structure assignment.
1024 (Thanks to Nicolas Neuss.)
1026 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
1028 (finalize_fd_sets): Added empty statement after last case label.
1029 (Thanks to Nicolas Neuss.)
1031 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
1034 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
1036 * init.c, readline.c: OK, I won't have these readline.x bug
1037 reports anymore. We've had them since April. The current reason
1038 is a completely unintelligible failure of totoro.red-bean.com to
1039 do the test for rl_getc_function in libreadline correctly. This
1040 kludge overrides the test if we're on totoro so that the snapshot
1041 generation process can work.
1043 * readline.c: Define a strdup replacement if not existent on system.
1045 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1047 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
1048 This change makes scm_make_vector R5RS compatible. We cannot keep
1049 the third argument since people want to be able to deduce the form
1050 of the C function call only by looking at R5RS. (At the same time
1051 we have removed some unnecessary complexity!)
1053 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
1054 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
1055 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
1056 argument in call to scm_make_vector.
1058 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1060 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
1061 This macro is useful in applications.
1063 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1065 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
1066 (scm_parse_path, scm_search_path): New Scheme level procedures.
1068 * load.h (scm_internal_parse_path, scm_parse_path,
1069 scm_search_path): Declared.
1071 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1073 * filesys.c (dirname, basename): New procedures.
1075 * init.c (scm_boot_guile_1): Removed condition around
1078 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
1079 new data type (guards) for representation of C level guards and
1080 data on the wind chain.
1081 (scm_internal_dynamic_wind): New function.
1083 * dynwind.h: Declare scm_internal_dynamic_wind.
1085 * root.h (scm_root_state): Added scm_cur_loadp.
1087 * root.c (mark_root): Added comment about cur_loadp.
1089 * load.c: #include "dynwind.h";
1090 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1093 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1095 * ports.c (current-load-port): New procedure.
1097 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1099 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1100 not a tty, return #f.
1102 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1103 to Julian Satchell and Roland Kaufmann.)
1105 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1106 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1108 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1110 * debug.h, debug.c (scm_start_stack): New function. Implements
1111 the guts of old scm_m_start_stack.
1113 * debug.c (scm_m_start_stack): Use scm_start_stack.
1115 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1116 start_stack and restart_stack. (These have static scope.)
1118 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1120 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1121 readline functions to come in release 2.3. (Thanks to Chet
1123 (handle_errors): Use the above functions.
1125 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1127 * readline.c: Improvements for readline support: Handle errors
1128 better; Implement before-read-hook.
1130 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1132 * init.c (scm_boot_guile_1), readline.c: Test for
1133 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1134 assure that we have version >= 2.1.)
1136 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1138 * readline.c (scm_readline): Defer interrupts while we're calling
1141 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1142 away the string to add_history.
1143 (completion_function): Do completion for readline. (Thanks to
1145 (scm_filename_completion_function): New procedure: Filename
1147 (current_input_getc): New function. Use this one instead of
1148 standard getc from readline.
1150 * throw.c, throw.h (scm_handle_by_throw): New function: This
1151 handler throws errors to next handler on the dynwind chain.
1153 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1155 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1158 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1160 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1162 (scm_procedure_properties): Modified to return arity together with
1164 (scm_procedure_property): Added the read-only property `arity'.
1165 (scm_set_procedure_property_x): It is an error to set the `arity'
1168 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1169 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1171 * procprop.h (scm_sym_arity): New symbol.
1173 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1174 to set the dispatch procedure of an operator or entity object.
1176 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1177 Made procedure slots read-only.
1179 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1180 scm_tcs_cons_gloc case in zero args switch; Fixed args
1181 construction for operators in scm_tcs_cons_gloc case in two args
1184 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1186 * fluids.c: Removed use of assert.h (in order to avoid
1189 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1191 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1193 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1194 change makes the evaluator safer at the cost of evaluation speed.
1195 It handles the case when the user has added a non-immediate
1196 improper end of the application form, e.g., `(+ 0 . x)'.
1197 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1198 minimize the extra cost as much as possible. The new code is
1199 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1200 problem with structs planted directly in the code (e.g. by a
1201 macro). This no longer causes segmentation fault. (Thanks to
1204 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1205 arg `proc' in order to be able to throw errors; New argument
1208 * Removed extra #include "debug.h"
1210 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1212 * scmsigs.c: Declare usleep as returning void on some systems.
1213 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1216 * coop.c (usleep): Return void on some systems.
1218 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1220 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1222 * coop.c: Changed return type of usleep to int.
1224 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1225 isn't found in the OS.
1227 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1228 isn't enabled. (Thought that I had made this change ages ago...)
1230 * iselect.c: Declare bzero if not defined by OS.
1232 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1234 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1235 condition. (Thanks to John Tobey.)
1237 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1238 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1241 * __scm.h: Start the long-term project of moving to POSIX threads.
1242 Phase 1: Classification of all critical sections.
1243 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1244 for A sections. (See comments in __scm.h for details.)
1246 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1247 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1249 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1251 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1252 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1253 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1254 dependencies on $(srcdir)/Makefile.in
1255 $(top_builddir)/config.status in order to avoid circularity.
1257 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1258 from argc if argc was 0 initially.
1260 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1261 in generation of libpath.h.
1263 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1265 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1266 libguile from 2 to 3.
1268 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1270 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1272 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1274 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1275 scm_set_port_column_x, scm_port_filename,
1276 scm_set_port_filename_x): Removed optional arguments. Added
1277 proper argument checking.
1279 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1280 stack size in machine words.
1282 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1283 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1284 to Ole Myren Röhne.)
1286 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1288 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1289 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1291 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1294 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1295 procedure apply: Copy argument lists before pushing them unto the
1296 environment so that the environment won't get mutated due to
1297 manipulation of procedure arguments. This should perhaps be
1298 regarded as a temporary solution until someone finds a more
1299 efficient one. (Thanks to Maciej Stachowiak.)
1301 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1303 * script.c (scm_compile_shell_switches): Use "guile" as default
1304 zero arg if argc is NULL.
1306 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1308 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1309 is zero. (Thanks to Dirk Herrmann.)
1311 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1313 * ports.c (scm_add_to_port_table): First line is now line 0
1314 (was 1). (Interface changed according to suggestion by Per
1317 * backtrace.c (display_header): Add 1 to line and column numbers
1318 when presenting them to the user.
1320 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1321 from debug.c --> eval.c
1323 * eval.h, eval.c (scm_eval_options_interface): New options
1325 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1326 i.e. stacks for new threads.
1328 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1330 * eval.c (unsafe_setjmp): Removed with #if 0.
1332 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1335 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1336 to avoid compiler warnings.
1338 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1340 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1342 * throw.c (handler_message): Print message on current error port
1343 instead of default error port. (Thanks to Maciej Stachowiak.)
1345 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1347 * ports.c (scm_add_to_port_table): allocate in units of
1348 struct scm_port_table *, not struct scm_port_table.
1349 * posix.c (scm_close_pipe): remove the port from the port table
1351 Thanks to Rob Engle for both fixes.
1353 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1355 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1356 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1358 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1360 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1362 * backtrace.c (display_error_body, display_backtrace_body),
1363 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1364 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1365 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1366 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1369 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1370 don't receive the jmpbuf arg anylonger.
1371 (scm_catch): Don't accept a #f tag.
1372 (scm_throw): Check that key is a symbol.
1373 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1375 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1377 * async.c (async_pending): Removed declaration.
1379 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1381 * dynwind.c (scm_wind_chain): New debug function.
1383 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1384 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1385 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1386 extra layer of functions around the body and handler of a thread.
1387 This extra layer makes sure that the handler is called in the
1388 dynamic context of the surround (= empty dynwind list), but under
1389 the *dynamic root* of the body. We can not use the dynamic root
1390 of the surround since that root belongs to another thread => stack
1391 is not handled correctly. It may seem ugly to use this extra
1392 layer, but the extra cost in terms of execution time is really
1393 negligible compared to the total amount of time required to create
1394 a thread, and it would reduce maintainability to duplicate the
1395 crucial and complicated steps performed by cwdr.
1397 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1398 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1399 get re-enabled. The important effect of this is that interrupts
1400 are blocked during thread switching so that thread data structures
1401 don't risk getting messed up by an unfortunate signal.
1402 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1403 seems to do more aggressive optimization which actually move
1404 instructions around in these macros in a fatal way. Therefore:
1405 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1406 just superstitious...)
1407 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1408 This macro should be used instead of SCM_ASYNC_TICK since the
1409 latter doesn't do context switches any more.
1411 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1412 instead of SCM_ASYNC_TICK.
1414 * coop.c, iselect.c: Since thread switches are now performed with
1415 interrupts masked, we can't use the old mechanism of delivering
1416 signals immediately when they arrive. Signals must instead be
1417 delivered when the asyncs run *after* the end of the critical
1418 section in scm_internal_select. But this also means after context
1419 switch so that the signal will be delivered to a different thread.
1420 To avoid this, I have changed the protocol of
1421 coop_wait_for_runnable_thread and friends so that they are allowed
1422 to return the original thread. So, if a signal arrives during
1423 scm_internal_select, we won't any longer be forced do a context
1424 switch, but can remain in the same thread and deliver the signal
1427 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1428 scm_asyncs_pending and made it global.
1430 * iselect.c: Small fixes.
1432 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1433 coop_condition_variable_init, coop_condition_variable_wait,
1434 coop_condition_variable_signal): Changed return type from `void'
1435 to `int'. This is to adhere closer to the pthreads interface.
1436 This, in turn, is part of an attempt to provide C versions of the
1437 mutex and condition variable primitives which can be part of a
1438 frontend to COOP or pthreads.
1440 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1441 coop_condition_variable_destroy): New functions.
1443 * coop-threads.c (scm_wait_condition_variable): Use
1444 coop_condition_variable_wait_mutex.
1446 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1447 Definitions moved to coop-defs.h.
1449 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1450 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1451 scm_cond_destroy): New C interface to mutecis and cond vars.
1453 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1455 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1457 * iselect.c: Now several threads can wait on the same file
1458 descriptor. The behaviour is compatible with OS select: All
1459 threads waiting for the fd return with the same status.
1461 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1463 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1464 Can spawn a thread from application C code.
1466 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1468 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1469 gh_doubles2scm): New functions.
1471 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1473 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1474 commented-out version of gh_eval_str()
1476 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1478 * socket.c (scm_bind): free soka after use.
1480 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1482 * stime.c (tzvar): new variable.
1483 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1484 avoid memory leaks when allocating.
1486 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1488 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1491 * gc.c, tags.h: Doc fixes.
1493 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1495 * eval.c (macro-eval!): Removed. This function was a design bug.
1496 It allowed memoized code to leak out to the scheme level. Most
1497 things that you could do with `macro-eval!' can be done with
1500 1997-12-20 Tim Pierce <twp@skepsis.com>
1502 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1503 scm_fgets now depends on ftell(3) to know how many bytes were
1506 1997-12-15 Tim Pierce <twp@skepsis.com>
1508 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1509 dealing with strings.
1511 1997-12-13 Tim Pierce <twp@skepsis.com>
1513 Make %read-line more suitable for implementing read-line efficiently.
1514 * ioext.c (scm_read_line): Strip the terminating newline from a
1515 string, and return a cons of the string and its terminator.
1517 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1518 of the string that is read is stored in this memory location.
1519 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1520 * genio.c, genio.h (scm_do_read_line): Update caller.
1521 * ports.h (scm_ptobfuns): Update typedef.
1522 * fports.c (scm_fptob, scm_pipob): Update struct.
1524 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1526 * filesys.c (set_element): Return file descriptor.
1527 (fill_select_type): Return the highest file descriptor.
1528 (scm_select): Tell select about the highest file descriptor. On
1529 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1530 Therefore the extra overhead for calculating the maximum fd seems
1531 to be more than compensated. Is this correct? In any case,
1532 scm_internal_select will be much faster with this info.
1533 (scm_select, fill_select_type, set_element): Don't accept any kind
1534 of object in the file descriptor list or vector.
1536 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1538 * iselect.c (finalize_fd_sets): Bugfix.
1540 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1542 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1543 when using scm_internal_select (since we might switch to another
1546 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1548 * simpos.c (scm_system): always define: use sysmissing if not
1549 available. Check for HAVE_SYSTEM instead of _Windows (does
1550 Windows lack system or does it have an unusable one?).
1551 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1552 Let the argument be optional: if not supplied, call system(NULL).
1554 * ports.c (scm_close_port): relax the type check from OPPORTP to
1555 PORTP; closing a closed port is allowed.
1557 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1559 * fports.c (scm_fgets): Return if the last char in a chunk is
1560 newline. When fgets returns a string whose length is `size-1', it
1561 is ambiguous whether a whole line was retrieved, so we must check
1562 explicitly whether a line terminator is present.
1564 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1566 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1567 before taking the CDR. (Thanks to Harald Meland.)
1569 * filesys.c (scm_stat): Slightly optimized.
1571 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1573 * ports.c (scm_close_port): Make sure the port is open before
1576 * guile-snarf.in: Pass args through to gcc in a way that preserves
1577 whitespace boundaries. (Thanks to Greg Badros.)
1579 1997-12-02 Tim Pierce <twp@skepsis.com>
1581 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1582 statement. (Thanks to Doug Evans for pointing this out.)
1584 1997-12-01 Tim Pierce <twp@skepsis.com>
1586 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1588 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1590 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1591 errno macro expansion of this field name. (errno is a C
1592 preprocessor macro on some systems.)
1594 1997-11-29 Tim Pierce <twp@skepsis.com>
1596 * iselect.c: Doc fix.
1598 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1600 * init.c (scm_start_stack): Removed initialization of
1601 scm_the_last_stack_var.
1603 * backtrace.h: Declare scm_the_last_stack_var.
1605 * backtrace.c: Define scm_the_last_stack_var.
1607 * root.c (mark_root): Don't mark the_last_stack_var.
1609 * root.h (scm_root_state): Removed the_last_stack_var.
1611 * throw.c: Added #include "fluids.h"
1612 (ss_handler): `the-last-stack' is now a fluid.
1614 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1615 --> the_last_stack_fluid.
1617 * backtrace.c: Added #include "fluids.h"
1618 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1619 (scm_backtrace): `the-last-stack' is now a fluid.
1621 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1622 after scm_init_fluids.
1624 1997-11-28 Tim Pierce <twp@skepsis.com>
1626 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1628 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1629 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1631 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1633 * iselect.c (coop_next_runnable_thread,
1634 coop_wait_for_runnable_thread): Disable interrupts so that no
1635 async is executed before a potential error_revive.
1636 (scm_internal_select): Disable interrupts during the parts of the
1637 code which manipulate the sleep queue and the file descriptors.
1639 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1641 * Makefile.am: Added iselect.c and iselect.h.
1643 * coop.c (coop_qinit): Initialize fields used by
1644 scm_internal_select.
1645 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1646 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1647 replacement in iselect.c.
1648 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1649 coop_join): If GUILE_ISELECT enabled, use
1650 coop_wait_for_runnable_thread instead of
1651 coop_next_runnable_thread.
1652 (usleep, sleep): New replacements for system functions if
1653 GUILE_ISELECT is enabled.
1655 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1657 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1659 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1660 iselect.h. Implement Scheme level `select' using
1661 scm_internal_select. (See NEWS.)
1663 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1665 * init.c: Call scm_init_iselect.
1667 * iselect.h, iselect.c: New files. Implements
1668 scm_internal_select. (See NEWS.)
1670 1997-11-27 Tim Pierce <twp@skepsis.com>
1672 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1673 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1674 and scm_must_free, since ultimately the string returned will be copied
1675 by scm_makfrom0str anyway. Also, read any characters that may have
1676 been pushed onto the port with scm_ungetc.
1677 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1678 * ioext.c (scm_read_line): Free string after Guilifying it.
1679 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1681 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1683 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1685 * gh.h: Safely wrap prototypes for c++ usage.
1687 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1689 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1690 gh_repl (argc, argv).
1692 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1694 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1695 and to invoke scm_shell().
1696 (gh_launch_pad): took out the loading of boot-9.scm from here,
1697 since it is probably best to let the user control that. In fact,
1698 gh_repl() now invokes scm_shell() which does that.
1700 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1702 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1708 yesterday's underscore patch. (Thanks to Marius Vollmer for
1711 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1713 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1714 DLSYM_ADDS_USCORE is not defined.
1716 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1718 * gh_data.c (gh_uniform_vector_length):
1719 (gh_uniform_vector_ref): started implementing the uniform types in
1722 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1724 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1725 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1727 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1729 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1730 configure.in was changed).
1732 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1734 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1735 * Makefile.in: Regenerated.
1737 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1739 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1740 OPORT is an `open' port, not an output port.
1742 * filesys.c (scm_close, set_element, get_element, scm_chown,
1743 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1744 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1745 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1746 scm_close_port, scm_port_line, scm_set_port_line_x,
1747 scm_port_column, scm_set_port_column_x, scm_port_filename,
1748 scm_set_port_filename_x, scm_port_mode,
1749 scm_close_all_ports_except, scm_set_current_output_port,
1750 scm_set_current_error_port): Likewise
1751 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1752 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1754 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1755 * backtrace.c (display_backtrace_body): Likewise
1756 * fports (scm_setvbuf): Likewise
1757 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1758 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1759 scm_getpeername, scm_send, scm_sendto): Likewise
1760 * unif.c (scm_uniform_array_write): Likewise
1762 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1764 Minor problems with substring-related tag changes.
1765 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1766 exactly what we want to leave in to detect substrings.
1767 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1768 * tags.h: Fix diagrams and comments describing the S tag bit;
1769 remove vestigial remarks about the D tag bit.
1770 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1771 * strings.c: Formatting tweaks.
1773 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1774 variable first; then SCHEME_LOAD_PATH, with a warning message.
1775 (scm_parse_path): New function.
1776 * script.c: Doc fixes.
1778 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1780 Readline support, from Daniel Risacher.
1781 * readline.c, readline.h: New files.
1782 * init.c: #include "readline.h".
1783 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1784 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1785 * Makefile.in: Regenerated.
1786 * scmconfig.h.in: Regenerated, after change to ../configure.
1788 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1790 * gh.h: gh_vector_set -> gh_vector_set_x
1792 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1794 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1795 with the ! -> _x mapping when going from Scheme to C.
1797 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1799 * gh.h (gh_reverse):
1807 (gh_assoc): added these gh_ functions implemented as macros.
1809 * gh_predicates.c (gh_null_p):
1810 (gh_string_equal_p): added these two missing predicates.
1812 * gh_list.c (gh_append):
1817 (gh_set_cdr_x): added these routines as I go through and try to
1818 complete the picture R4RS functions that should be mirrored in the
1821 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1823 * tags.h (scm_tc7_substring): Changed the comment and code to
1824 conform with the changes below. Folks! We have suddenly two new
1825 free tc7 codes!!! Jummy, jummy!
1827 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1829 * Makefile.in: Rebuilt.
1830 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1832 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1833 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1848 * tags.h (SCM_TYP7SD): Removed.
1849 (SCM_TYP7D): Removed.
1850 (scm_tc7_mb_string): Removed.
1851 (scm_tc7_mb_substring): Removed.

1855 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1856 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1858 Don't include "mbstrings.h".
1859 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1860 (SCM_SYMBOL_SLOTS): Define as 4.
1861 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1862 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1863 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1864 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

1883 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1885 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1887 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1889 * gh_test_c.c (c_vector_test): some improvements on the vector
1892 * gh.h (gh_vector): this used to exist but do the wrong thing.
1893 Now it (almost) does the right thing, though it takes a list
1894 instead of the individual arguments. I need to see how it could
1896 (gh_list_to_vector): added this function as a macro. Corresponds
1897 to Scheme's (list->vector ...).
1898 (gh_vector_to_list): added this function as a macro. Corresponds
1899 to Scheme's (vector->list ...).
1901 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1902 gh_vector_ref, so that it resembles the Scheme routines more.
1903 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1904 resembles the Scheme routines more.
1905 (gh_make_vector): this used to be (stupidly) called gh_vector().
1906 This is the right name, since it does the same thing as the Scheme
1907 (make-vector ...) procedure.
1909 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1911 * ports.h: #include "libguile/print.h"
1913 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1914 Some indentation fixes.
1916 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1917 longer a user field; New field: class_flags.
1919 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1921 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

1924 gh_int2scmb(), which is now tagged as obsolete.
1926 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1928 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1929 macros should by convention not test for NIMPness.)
1930 (SCM_COERCE_OPORT): Adjust indentation.
1932 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1933 SCM_NIMP test before SCM_PRINT_STATE_P.
1935 * struct.c, struct.h, gc.c: Renamed:
1936 scm_struct_i_layout --> scm_vtable_index_layout
1937 scm_struct_i_vcell --> scm_vtable_index_vcell
1938 scm_struct_i_vtable --> scm_vtable_index_vtable
1939 scm_struct_i_printer --> scm_vtable_index_printer
1940 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1942 * struct.c (scm_print_struct): Use new printer slot; Default
1943 printing: Also output hex code of vtable so that type identity
1944 will be indicated as well.
1945 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1946 Removed struct_printer_var; Removed struct-vtable-offset;
1947 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1948 vtable-offset-user): New constants.
1950 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1951 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1952 If this slot contains a procedure, use that to print structures of
1953 the type represented by this vtable.
1955 * print.c (scm_iprin1): Don't print arguments of macro
1956 transformers. (They are always: exp env.); Bugfix: Unmemoize
1957 transformer source with correct environment.
1959 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1961 Streamlining of call-with-dynamic-root:

1964 there is now only one catch.
1965 (cwdr_outer_body): Removed.
1966 (cwdr_handler): New function.
1967 (scm_internal_cwdr): New function to perform the function of cwdr
1968 but take args that are more useful to C code. Also, the handler
1969 is now invoked *outside* of the new dynamic root, like the docs
1970 say. We no longer have to catch absolutely all errors, the caller
1971 is responsible for using a handler that does not throw, if he
1973 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1974 * root.h (scm_internal_cwdr): New prototype.
1976 Even more but risky streamlining:
1978 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1979 allocation of the jumpbuf of a root continuation. The changes
1980 below are controlled by it. They are now deactivated.
1981 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1982 the JMPBUF of the scm_rootcont to NULL before returning.
1984 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1985 when they are non-NULL.
1986 (scm_gc_mark): Likewise, mark only when non-NULL.
1988 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1989 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1991 * gc.c (scm_done_malloc): New function.
1992 gc.h (scm_done_malloc): New prototype.
1994 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1995 (struct scm_print_state) [revealed]: New field.

1997 type checking purposes.
1998 (scm_valid_oport_value_p): New prototype.
2000 * print.c (scm_valid_oport_value_p): New function to check whether
2001 a certain value is acceptable as a port argument.
2002 (scm_print_state_vtable): New variable.
2003 (scm_free_print_state): Set `revealed' field to false.
2004 (scm_iprin1): Call user supplied closure printer with
2005 scm_printer_apply. Print in the traditional way when there isn't
2006 one or when it returns #f.
2007 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
2008 Accept a port/print-state pair in addition to just a port.
2009 (scm_prin1): Don't return the print_state to the pool when it has
2011 (scm_printer_apply): Set `revealed' field of print_state to true.
2012 (scm_init_print): Set scm_print_state_vtable.
2013 (print_state_fluid, print_state_fluid_num): Removed.
2015 * throw.h (scm_handle_by_proc_catching_all): New prototype
2016 throw.c (scm_handle_by_proc_catching_all): New function
2018 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
2020 * Makefile.in: Regenerated with automake 1.2c.
2022 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
2024 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
2025 was looping endlessly.
2027 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
2029 * strports.c (scm_eval_string): Don't close the port.
2031 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
2032 former returns a nice normal integer. (Thanks to Daniel
2035 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
2037 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
2038 makefile variable as a build parameter called LIBS. The
2039 build-guile program will use this, for the time being.
2040 * Makefile.in: Regenerated.
2042 Thanks to Shiro Kawai:
2043 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
2044 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
2047 * Makefile.in: Regenerated with automake 1.2a.
2049 * script.c (scm_compile_shell_switches): If we hit the -c or --
2050 arguments, don't set the car of (command-line) to scm_usage_name,
2051 the prettified name of the guile executable; give it the full
2052 path, the way shells usually handle $0.
2054 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2056 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
2057 Scheme-level name `array-map' and renamed `serial-array-map' to
2058 `serial-array-map!'.
2060 * backtrace.c: Introduced exception handlers which now enclose
2061 `display-error' and `display-backtrace' so that error reporting
2062 won't get into infinite loops if an error occurs during displaying
2063 of the error. This can very easily happen with user supplied
2064 print call-back routines.
2066 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2068 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
2069 the names `serial-array-map' and `array-map' should be removed.)
2071 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2073 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2074 Added #include "objects.h"
2076 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2077 Add #include "feature.h".
2079 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2080 (modinclude_HEADERS): Added objects.h.
2082 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2083 This test is needed at many places in the code and should be
2084 abstracted. (Motivated by the need of this test in libguiletk.)
2086 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2087 (scm_eval_string), load.c (scm_primitive_load,
2088 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2089 Use SCM_EOF_OBJECT_P.
2091 * eval.c (scm_init_eval): Add feature `delay'.
2093 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2095 * scmhob.h: Removed.
2097 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2099 * list.h (SCM_LISTn): New macros. Make list creation in C code
2100 prettier. The idea comes from STk.
2102 * sequences.h, sequences.c, append.h, append.c: Removed. These
2103 files implemented non-R4RS operations which would encourage
2104 non-portable programming style and less easy-to-read code.
2106 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2109 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2110 sequences.h, #include append.h.
2112 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2115 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2117 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2119 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2121 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2123 * eval.c: Added #include "objects.h"
2125 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2128 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2129 adjacent smob numbers.
2131 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2133 * procprop.h: Added declaration of scm_i_inner_name.
2135 * gsubr.c: New global symbol scm_i_inner_name.
2137 * debug.c (scm_procedure_name): Try procedure property
2138 `inner-name' if `name' fails.
2140 * print.c (scm_iprin1): Use scm_macro_name.
2142 * eval.c (scm_m_define): Give names to macros as well; Only the
2143 first top-level definition gives a procedure/macro a name.
2144 Otherwise confusing names can turn up in backtraces.
2145 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2146 `name'; Give names to macros as well.
2148 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2149 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2152 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2154 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2156 (prinmacro): Removed. The code has been moved/merged into print.c
2157 in order to decrease code redundancy. We want macros to print in
2158 a way equivalent to procedures, and it would be silly to duplicate
2159 the required code. (We don't want to maintain two places.)
2160 (macrosmob): Print field is now a NULL pointer.
2162 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2163 scm_macro_transformer): New prototypes.
2164 (scm_tc16_macro): Declared.
2166 * print.c (scm_iprin1): Added code for printing of macros. Macros
2167 are now printed in a way equivalent to procedures.
2169 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2171 * procs.h (scm_closure_p): Added declaration.
2173 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2175 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2176 Shouldn't pass "heap" as the subr name.
2178 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2180 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2181 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2182 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2183 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2184 SCM_BOOL_T. Any non-false value is true.
2186 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2188 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2189 scm_gensym): Added prototypes.
2191 * symbols.c (scm_gensym): New function. This will speed up
2192 certain types of applications (such as macro systems) which
2193 generate lots of symbols.
2195 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2197 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2199 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2201 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2202 specifier, since (2) or (2 . 3) would cause SEGV.
2203 (scm_transpose_array): more argument checking fixes.
2205 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2207 * Makefile.in: Regenerated.
2209 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2211 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2213 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2215 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2217 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2219 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2220 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2223 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2224 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2225 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2226 scm_array_p, scm_array_rank, scm_array_dimensions,
2227 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2228 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2229 scm_array_prototype): Added case scm_tc7_wvect.
2231 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2233 * errno.h: prototype for scm_strerror.
2234 * error.c (scm_strerror): new procedure.
2236 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2238 * list.c (scm_list_append_x): Allow non-pair as last argument.
2239 This is consistent with the R4RS append and is probably the
2240 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2242 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2244 * stime.h: prototype for scm_times.
2245 * stime.c (scm_times): new procedure.
2246 * ioext.c (scm_fseek): if the first argument is a file descriptor
2248 (scm_ftell): if the first argument is a file descriptor call lseek
2250 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2251 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2253 (scm_chown): if the first argument is a port or file descriptor,
2255 (scm_truncate_file): new procedure.
2256 Add DEFER/ALLOW INTS to a few other procedures.
2257 (scm_fsync): new procedure.
2258 (scm_open_fdes): new procedure.
2259 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2261 (scm_fcntl): the first argument can now be a file descriptor. The
2262 third argument is now optional.
2264 * posix.c (scm_execl, scm_execlp): make the filename argument
2265 compulsory, since omitting it causes SEGV.
2266 (scm_sync): return unspecified instead of #f.
2267 (scm_execle): new procedure.
2268 (environ_list_to_c): new procedure.
2269 (scm_environ): use environ_list_to_c. disable interrupts.
2270 (scm_convert_exec_args): take pos and subr arguments and
2271 improve error checking.
2273 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2275 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2276 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2277 argument to SCM_ASSERT. Furthermore, the name of the function
2278 should be passed as first argument when signalling
2279 SCM_WNA. (Thanks to Thomas Morgan)
2281 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2282 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2283 dispatches on the number of actual args has a default case
2284 reporting an internal error. This is a vestige from a version
2285 that mallocated a SCM vector to hold the arguments. In the
2286 current version this check is too late: if it ever happens we will
2287 have already overstepped the bounds of the array.
2289 Also, the patch [...] adds a check for too many actual arguments."
2291 mdj: Removed check for "internal programming error".
2293 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2295 * gh_io.c (gh_write): New function.
2297 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2298 throw.c (scm_internal_stack_catch): New sibling to the other catch
2299 functions. Code moved from gh_eval.c.
2300 throw.h: Added header.
2301 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2302 scm_internal_stack_catch.
2304 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2306 * ioext.h: fix up prototypes.
2307 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2308 Scheme name is now dup->fdes.
2309 (scm_dup_to_fdes): make the second argument optional and
2310 fold in the functionality of scm_primitive_dup.
2311 (scm_primitive_dup): deleted.
2313 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2315 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2316 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2317 ultrix are defined. Use setvbuf instead of setbuf.
2318 (scm_setvbuf): new procedure.
2319 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2320 (scm_setfileno): moved from ioext.c.
2321 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2322 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
2324 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2326 * fluids.c (scm_fluid_p): New function.
2327 * fluids.h (scm_fluid_p): New prototype.

2332 state as nested data while they are printed.
2333 (print_state_fluid, print_state_fluid_num): New variables.
2334 (scm_init_print): Initialize them.
2335 (scm_iprin): If print_state_fluid carries a print_state, use that
2336 instead of creating a new one.
2337 (scm_printer_apply, apply_stub, struct apply_data): New
2338 definitions to help with calling printer functions written in
2340 * print.h (scm_printer_apply): New prototype.

2353 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2354 SCM_ASSERT: arg comes before pos.
2356 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2358 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2359 to a list of length zero correctly.
2361 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2363 Supply an `fgets' method for port objects to do fast line i/o.

2377 * ioext.h: removed scm_duplicate_port prototype.
2379 * ioext.c (scm_primitive_dup2): return the new file descriptor
2380 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2382 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2383 stream has been set.
2384 (scm_duplicate_port): deleted, there's now an implementation in
2386 (scm_primitive_dup2): do nothing if newfd == oldfd.
2388 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2390 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
2393 * ioext.h: new prototypes.
2394 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2396 * fluids.c (next_fluid_num): don't do
2397 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2399 * ports.h: prototypes too.
2400 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2402 * fports.h: prototype too.
2403 * fports.c (scm_evict_ports): moved from ioext.c.
2405 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2412 and ports (scsh compatible).
2414 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2417 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2419 * fluids.c, fluid.h: New files.
2420 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2421 (modinclude_HEADERS): Added "fluids.h"

2429 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
2430 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2431 unique for the new root when it has a parent.
2433 * smob.h: Include "libguile/print.h" to make scm_print_state
2436 * dynl.c (free_dynl_obj): New function to free the dynamic object
2437 data. (dynl_smob): Use it.
2438 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2439 the dynamic object data below the linking of the object to avoid
2440 memory leak when the linking code throws an error. Now the code
2441 leaks a whole dynamically linked library when must_malloc throws,
2442 but that should be much less likely.
2444 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2446 Changes to compile under gnu-win32, from Marcus Daniels:

2448 (scm_localtime): Change SCM_EOF to SCM_EOL.
2449 (scm_mktime): Likewise.
2450 * socket.c: Don't include sys/un.h unless autoconf tells
2451 us Unix domain sockets are available.

2479 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2480 scm_misc_error, not SCM_EOF.
2482 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2483 arguments for formatting the error message, not SCM_BOOL_F. I
2484 think this is left over from the (eq? '() #f) days.
2486 * read.c (recsexpr): Give this a dummy definition if
2487 DEBUG_EXTENSIONS isn't #defined.
2489 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2491 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2494 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2496 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2499 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2501 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2502 alloca.lo will be included in @LIBLOBJS@. Something better than
2503 this should be possible.
2504 * Makefile.in: Regenerated.
2506 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2508 * simpos.h: prototype for scm_primitive_exit.
2509 * simpos.c (scm_primitive_exit): new procedure, terminates the
2510 process without unwinding the stack.
2512 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2514 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2515 argument and logior its components together, so the user doesn't
2516 have to do this explicitly. Also, if regexp/basic is supplied, then
2517 turn off REG_EXTENDED.
2518 (scm_init_regex_posix): New regexp/basic symbol.
2519 (REG_BASIC): #define this if it is not already present.
2521 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2523 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2524 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2525 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2526 (DISTCLEANFILES): New target, clean *.x.
2527 * Makefile.in: Regenerated.
2529 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2531 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2532 years in usage message.
2534 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2535 * Makefile.in: Regenerated.
2537 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2538 flag; I don't think we support it.
2539 (scm_make_regexp): Make sure the user doesn't pass the
2542 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2544 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2545 name them according to the SCSH convention: regexp/mumble.
2547 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2549 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2551 * Makefile.am (libpath.h): Include the values of all the standard
2552 Makefile directory variables. Print a message, but don't print
2554 (versiondat.h): Print a message, but don't print all the commands.
2555 * load.c: #include "alist.h".
2556 (init_build_info): New function.
2557 (scm_init_load): Call it.
2558 * Makefile.in: Regenerated.
2560 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2562 * root.c: Establish a reliable catch-all handler for the new root.
2563 After all the Scheme handler function might signal an error too,
2564 and we don't want to lose that.
2565 (cwdr_inner_body): Renamed from cwdr_body.
2566 (cwdr_outer_body): New function, to establish the user's handler,
2567 and pass control to cwdr_inner_body.
2568 (cwdr): Establish the reliable catch-all handler here, and pass
2569 control to cwdr_outer_body.
2570 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2571 the user's handler through to cwdr_outer_body.
2572 * throw.c (scm_handle_by_message): Move guts into....
2573 (handler_message): New static function.
2574 (scm_handle_by_message_noexit): New function.
2575 * throw.h (scm_handle_by_message_noexit): New prototype.
2577 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2578 across this. Only works on GCC. Otherwise, we hope for the best.
2579 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2580 the feeling that real thread systems will not need this...
2582 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2584 Try to detect when people are using one version of libguile and a
2585 different version of ice-9. People have been skewing things and
2586 sending in bug reports.
2587 * Makefile.am (versiondat.h): New file to generate.
2588 * version.c: #include "versiondat.h", to get version info.
2589 (scm_libguile_config_stamp): New function.
2590 * script.c: #include "version.h".
2591 (scm_compile_switches): Call scm_version to get version number.
2592 * scmconfig.h.in, Makefile.in: Regenerated.
2593 * Makefile.in: Regenerated.
2595 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2596 primitive definitions under their Scheme names.
2598 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2599 1:2. Helps avoid confusion between installed and uninstalled libs.
2601 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2604 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2605 backslash from definition; this should be used like: GDB_INTERFACE;
2607 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2609 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2610 new port unbuffered until its stream has been set.
2612 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2614 * ports.h: new prototype.
2615 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2617 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2619 Make things compile neatly under Sun's C compiler.
2620 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2621 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2622 unsigned, because that's what the ANSI function takes.
2623 * extchrs.h (xmbtowc): Corresponding change to prototype.
2624 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2626 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2627 argument plain char *.
2628 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2630 * tag.c (scm_tag): Remove unreachable statement.
2631 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2632 top of the word, it should be unsigned.
2634 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2635 is defined, to avoid warnings; it's only used in the
2636 conflict-checking code. Which might go away anyway.
2637 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2638 conditionals; put the label definition in an #if too, to stifle
2641 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2642 ChangeLog-threads in the distribution.
2643 * Makefile.in: Regenerated.
2645 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2647 * guile-snarf.in: Changed regexp to support CPPs that insert
2648 whitespace between lexical tokens (which munges the `%%%' snarf
2651 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2653 * load.c (scm_init_load_path): Append $(datadir)/guile to
2654 %load-path, so modules do not have to be installed in Guile's
2655 current version directory.
2657 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2659 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2660 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2661 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2662 call the sysdep functions with deferred ints.
2663 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2664 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2665 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2668 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2671 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2673 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2675 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2677 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2680 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2682 * eval.c (scm_lookupcar1): New procedure to cope with a race
2683 condition during lookup (when using threads).
2684 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2685 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2688 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2690 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2691 supplied. (Change from Tim Pierce.)
2693 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2695 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2696 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2697 default and not `()'. `#f' is the canonical non-value in Scheme,
2700 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2702 * struct.c (struct_printer): New variable that holds a handle on
2703 the Scheme variable *struct-printer*. This variable can be set by
2704 Scheme code to override the printing of structures.
2705 (scm_print_struct): If struct_printer is set, call it. If it is
2706 not set, or returns #f, print the structure in the old fashion.
2707 Include "eval.h" for scm_apply.
2709 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2711 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2712 scm_struct_i_n_words to get the number of fields, not
2713 -scm_struct_n_extra_words.
2715 On the route to fancier struct printing:
2716 * struct.c (scm_print_struct): New function to print a structure.
2717 Include "genio.h" to support it. This function doesn't do
2718 anything interesting right now, but I think it should be here
2720 * struct.h: Include "print.h" and add prototype for
2722 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2723 print structures ourself.
2725 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2727 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2728 before applying the handler in case it doesn't return.
2730 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2732 * scmsigs.h, async.h: updated.
2734 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2737 * posix.c (scm_uname): interpret only negative values as an error.
2738 Solaris normally returns a positive value.
2740 * script.c (scm_compile_shell_switches): if we are not going into
2741 an interactive repl, set scm_mask_ints to zero so that asyncs can
2744 * simpos.c (scm_system): don't ignore/unignore signals around
2747 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2750 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2751 done in boot-9.scm instead.
2753 * scmsigs.c, async.c: Major rewriting of signal handling code.
2754 (scm_sigaction): new procedure.
2755 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2757 (scm_raise): return unspecified, throw error on failure.
2759 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2761 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2762 feature, to help boot-9.scm decide whether to import the regex
2765 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2767 * eval.c: Include scmconfig.h at the beginning of the file so that
2768 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2771 * regex-posix.c: #include "_scm.h" before conditionally #including
2772 <regex.h>; the former defines HAVE_REGCOMP.
2774 * regex-posix.c: #include <regex.h> conditionally, so the file is
2775 CPP'able (for dependency scanning) even on systems that don't have
2778 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2780 Add new R4RS-compliant syntax for keywords.
2781 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2782 regardless of the setting of the `keywords' read option.
2783 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2784 can be re-read no matter what the setting of the `keywords' read
2787 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2789 Add support for POSIX regular expressions.
2791 * regex-posix.c, regex-posix.h: New files. (Some code
2792 is taken liberally from rx/rgx.c in the old Guile dist.)
2794 * init.c: Include regex-posix.h.
2795 (scm_boot_guile_1): Call scm_init_regex_posix.
2797 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2798 Add regex-posix.[ch] sources.
2799 * Makefile.in: Regenerated.
2801 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2802 to do this automatically? It didn't for me, bleh.)
2804 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2806 * fports.c (print_pipe_port): New function.
2807 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2808 latter doesn't even take the right arguments.
2810 * Makefile.am: Increment shared lib revision number. I think
2811 sometimes the uninstalled Guile finds the installed shared lib;
2812 Gord says doing this might help. As things turned out, I can't
2813 say whether it does.
2814 * Makefile.in: Regenerated.
2816 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2817 passing it as the closure argument to scm_boot_guile. (Bill
2820 * ports.c (print_void_port, putc_void_port, puts_void_port,
2821 write_void_port, flush_void_port, getc_void_port, close_void_port,
2822 noop0): Use ANSI prototypes instead of K&R declarations, so the
2823 initialization of void_port_ptob gets aggressively type-checked.
2824 Fix arguments of print_void_port and write_void_port. (Bill

2860 * script.c (scm_find_executable): Use prototype-style definition
2861 here; apparently it's not quite right to have const in a prototype
2862 and then use a K&R declaration. I wonder if stuff like this will
2863 go away if we compile with -Wrequire-prototypes, or whatever that
2864 is... (Bernard URBAN)
2866 * scmhob.h: New text from Bernard URBAN.
2868 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2870 * script.c: Don't #define const on hpux. Configure takes care of
2871 this. (Thanks to Larry Schwimmer.)
2873 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2874 decide whether to #include <unistd.h>, instead of listing a bunch
2875 of systems. Don't #include stdio twice. Removed dyked-out
2876 definition of scm_find_impl_file.
2878 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2880 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2881 library version info to 1:0.
2882 * Makefile.in: Regenerated.

2888 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2889 throw.c: Update copyright years; these files have been worked on
2890 significantly in 1997, but only had copyright years for 1996.
2891 Also, change name of copyright holder on some from Mikael
2892 Djurfeldt to Free Software Foundation; he has signed papers
2893 assigning the changes to the FSF.
2895 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2896 reason not to give the user the option.
2898 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2899 Return #f on end-of-file when scanning table (i.e. when called
2900 with no arguments). Try to catch errors, when we can.
2901 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2903 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2904 external declarations. These are useful.
2906 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2908 * posix.c: don't include <sys/select.h> or define macros for
2909 select, since they were not used in this file.
2911 * filesys.c (scm_select): make the fifth parameter microseconds,
2912 not milliseconds. let the fourth parameter be either a real value
2913 or an integer or #f. The first, second and third arguments can
2914 now be vectors: the type of the corresponding return set will be
2916 (set_element, get_element): new static procedures.
2918 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2920 * strports.c (scm_eval_string): New function.
2921 (scm_eval_0str): Trivially re-implemented in terms of
2923 * strports.h (scm_eval_string): New extern decl.
2925 * net_db.c (h_errno): Add extern decl for this.
2927 * fports.c (local_pclose): New function.
2928 (scm_pipob): Use it in the initializer here.
2931 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2932 Use a meaningful error message when signalling an error. For
2933 this, scm_gethost must check h_errno rather than errno.
2935 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2937 * Makefile.in: Regenerated, using automake-1.1p.

2941 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2942 not SCM_UNSPECIFIED.
2944 * script.c (scm_compile_shell_switches): don't append (quit) if
2946 (scm_shell): call scm_exit_status and exit on the result of the
2949 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2951 Ensure that shared substrings are handled properly when passed to
2952 a system call or other foreign function. Many thanks to Tim
2954 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2955 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2956 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2957 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2958 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2959 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2960 (scm_display_error_message): use RO macros when strings may be RO.
2961 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2962 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2963 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2964 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2965 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2966 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2967 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2968 scm_strftime), vports.c (scm_make_soft_port): use
2969 SCM_COERCE_SUBSTR to make sure shared substrings are

2974 * error.c (scm_error): Add newline to error message.
2976 * init.c (scm_init_standard_ports): Doc fix.
2978 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2980 * dynl-shl.c: Completely replaced with new code from Bernard
2983 * script.c (scm_ice_9_already_loaded): New variable.
2984 (scm_compile_shell_switches): Use it.
2986 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2988 * filesys.c (scm_input_waiting_p): add missing third argument to
2991 * stime.c (scm_localtime): copy the result of localtime before
2992 calling gmtime in case they share a buffer.
2993 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2996 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2998 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
3000 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
3002 * Makefile.am (check-local): New target, which causes 'make check'
3003 to run gh_test_c and gh_test_repl, with some trivial input.
3004 * Makefile.in: Rgnrtd.
3006 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
3008 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
3011 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
3013 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
3014 sure how this was supposed to work.
3015 (scm_async_click): don't send SCM_TICK_SIGNAL.
3016 (scm_init_async): don't initialize %tick-thunk.
3018 * the following change doesn't affect the Scheme interface:
3019 gc-thunk is called at the end of garbage collection. however it's
3020 no longer implemented by pretending it's a signal.
3022 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
3023 system async corresponding to scm_gc_thunk.
3024 * async.h: declare scm_gc_async.
3025 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
3026 gc-thunk directly, instead of going through a signal handler.
3027 (scm_gc_async): new variable, points to the GC system-async.
3028 (scm_init_async): save the GC async as scm_gc_async instead
3029 of using system_signal_asyncs.
3030 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
3032 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
3034 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
3035 Don't screw up if we're interrupted.
3036 * Makefile.in: Regeneradet.
3038 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
3040 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
3042 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
3043 we're not using AM_INIT_GUILE_MODULE any more.
3044 * Makefile.in: Reneregated.
3046 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3048 Functions for finding variable bindings, grace à Tim Pierce.
3049 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
3050 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
3052 Get 'make dist' to work again.
3053 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
3054 * Makefile.in: Regenerated, like a surry without a fringe on top.
3056 Changes for reduced Guile distribution: one configure script,
3058 * configure.in, configure: Removed.
3059 * acconfig.h, acinclude.m4: Moved to parent directory, where the
3060 real configure script lives.
3061 * Makefile.in, scmconfig.h.in: Regenerated.
3063 * init.c: #include "script.h", to get prototype for script.c's
3066 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
3068 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
3069 scm_must_malloc, not raw malloc.
3071 * script.c (scm_compile_shell_switches): Dyke out debugging output
3074 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3076 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3078 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3079 system has them. Hope this is safe. Previously
3080 sys/timeb.h was included if HAVE_FTIME was defined or if
3081 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3082 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3084 * ioext.c (scm_setfileno): add missing third argument to
3085 scm_misc_error call.
3087 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3089 * eq.c (scm_equal_p): Correctly compare strings of different
3090 varieties. (Thanks to Tim Pierce.)
3092 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3094 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3095 #! block comment must occur on a line all by itself.
3097 Move most of the guts of shell command processing into libguile,
3098 so guile.c can be very small (and eventuallly auto-generated. (I
3099 mean, generated mechanically, not self-generated. Hmm.))
3100 * guile.c, script.c, script.h: New source files.
3101 * init.c (scm_boot_guile_1): Call scm_init_script.
3102 * libguile.h: #include "script.h".
3103 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3104 targets, for new executable.
3105 (libguile_la_SOURCES): Mention script.c.
3106 (modinclude_HEADERS): Add script.h.
3107 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3108 not dynamic linking is enabled. This is because we're generating
3109 executables now. Move CY_AC_WITH_THREADS call after those, so the
3110 values of cy_cv_threads_libs captures the libs chosen above.
3111 * Makefile.in, configure, aclocal.m4: Regenerated.
3113 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3114 We don't maintain this interface any more, and it just confuses
3117 * alloca.c: #include <scmconfig.h>, not <config.h>.
3118 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3119 it'll get included in disties.
3121 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3123 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3124 be distributed, because they confuse people.
3125 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3127 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3129 * configure.in: check for presence of gethostent (not present on
3130 OpenBSD by default).
3131 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3132 * configure, scmconfig.h.in: Regenerated.
3134 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3136 * backtrace.c (scm_backtrace): Split message string across
3137 newlines properly. GCC is more tolerant of this than other
3140 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3142 Merge threads directory into libguile.
3143 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3144 threads.h: New source files.
3145 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
3146 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3148 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3149 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3150 coop-threads.c.cygnus, coop-threads.h.cygnus.
3151 * configure.in: If we're using threads, include threads.o in
3153 * _scm.h, libguile.h: threads.h lives in this directory now.
3154 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3155 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3156 currently used, but brought along for information's sake.
3157 * ChangeLog-threads: log from old 'threads' directory.
3158 * Makefile.in, configure: Rebuilt.
3160 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3162 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3165 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3167 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3169 Merge GH interface library into libguile.
3170 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3171 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3172 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3173 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3175 (EXTRA_libguile_la_SOURCES): ... here.
3176 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3177 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3178 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3179 New variables, describing how to build the gh test programs.
3180 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3181 build the test programs, and we probably should have been linking
3182 libguile.la against them all along, to support AIX shared libs.
3183 Add cflags for threads to CFLAGS; add libs for threads to new
3184 variable THREAD_LIBS, used in Makefile.am.
3185 * ChangeLog-gh: log from old `gh' subdirectory.
3186 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3188 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3190 * acconfig.h: Undo change of Apr 9; including the definition of
3191 PACKAGE in the guile headers conflicts with applications' own
3193 * scmconfig.h.in: Regenerated.
3195 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3202 when PROC is receiving no arguments.
3204 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3206 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3207 have S_IFSOCK. This is the case under Ultrix.
3209 * posix.c (scm_status_exit_val, scm_status_exit_val,
3210 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3211 Ultrix versions of WIFSTOPPED, etc., which assume that their
3212 arguments are lvalues (hmm).
3214 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3216 * eval.c: Doc fixes.
3218 * throw.c: Doc fixes; rearranged.
3220 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3222 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3224 * acconfig.h: Added entry for PACKAGE.
3225 * scmconfig.h.in: Regenerated.
3227 Changes to work with automake-1.1n, which has better libtool support.
3228 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3229 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3231 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3233 * Makefile.in: Rebuild.
3235 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3237 * stime.c (scm_mktime): take an optional zone argument.
3238 (scm_localtime): check putenv return value.
3239 (scm_strftime, scm_strptime): moved from posix.c. move #include
3241 stime.h, posix.h: update prototypes.
3242 (bdtime2c, setzone, restorezone): new static procedures.
3243 (scm_mktime, scm_strftime): use them.
3244 (scm_strftime): don't call mktime before strftime. Use
3245 filltime for return value.
3246 (filltime): convert NULL zname to #f.
3247 (scm_strptime): return a count of characters consumed, not
3248 the remaining string.
3250 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3252 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3253 (scm_mktime): likewise.
3255 Uncomment localtime and mktime.
3257 * configure.in: add AC_STRUCT_TIMEZONE.
3259 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3261 * stime.c (scm_init_stime): don't define ticks/sec.
3262 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3263 return value problem and is still portable.)
3265 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3267 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3268 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3269 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3270 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3271 cpp_err_symbols.c): Corresponding changes.
3272 * Makefile.in: Regenerated.
3274 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3276 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3277 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3278 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3279 * putenv.c: new file, from sh-utils 1.12.
3281 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3282 since allocation isn't for Scheme objects.
3283 (scm_putenv): copy strings before placing in the environment.
3285 * stime.c (scm_current_time): throw an error if time returns -1,
3286 instead of returning #f.
3287 (scm_get_internal_real_time, scm_get_internal_real_time): use
3288 scm_long2num for return value instead of SCM_MAKINUM.
3290 * stime.h: prototypes updated.
3292 * stime.c (scm_time_in_msec): apparently unused, deleted.
3294 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3296 * configure.in: check for gettimeofday.
3298 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3299 which may be more usefully portable than a gettimeofday interface.
3301 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3303 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3305 * Makefile.in: Regenerated.
3307 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3309 * stime.c (filltime): recovered static procedure.
3310 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3313 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3314 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3316 * posix.c (scm_mknod): split the mode argument into type and perms
3317 arguments, like the extra fields returned by stat.
3319 * fports.c (scm_pipob): set the close, free and print procedures.
3320 (scm_close_pipe): new procedure.
3322 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3323 define them in boot-9.scm
3325 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3327 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3328 wan't defined. Don't include fd.h.
3330 * Previously fd.h was regenerated whenever configure was run,
3331 forcing a couple of files to be recompiled.
3333 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3334 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3335 Check for _fileno as well as _file.
3337 * ioext.c: don't fd.h.
3338 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3341 * Change the stratigy for getting information about errno
3342 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3343 generating lists of symbols during the build process, which will
3344 not always work, include comprehensive lists in the distribution.
3345 To help keep the lists up to date, the "check_signals" and
3346 "check_errnos" make targets can be used.
3348 * configure.in: don't check for a command to extract errno codes.
3349 * Makefile.am: update file lists, remove errnos.list and errnos.c
3350 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3351 check_errnos targets.
3352 (CLEANFILES): remove errnos.c and errnos.list, add
3353 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3354 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3355 * errnos.default: deleted.
3356 * cpp_signal.c: new file.
3357 * cpp_errno.c: renamed from errnos_get.c.
3358 * cpp_err_symbols, cpp_sig_symbols: new files.
3359 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3360 * error.c (scm_init_error): #include cpp_err_symbols instead of
3362 * posix.c (scm_init_posix): don't intern signal symbols. #include
3365 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3367 * strop.c (scm_i_index): allow the lower bound to be equal to the
3368 length of the string, so a null string doesn't always give an error.
3370 * posix.h: new prototypes.
3371 * posix.c (scm_status_exit_val, scm_status_term_sig,
3372 scm_status_stop_sig): new functions, as in scsh. They break down
3373 process status values as returned by waitpid.
3375 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3377 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3378 configure doesn't know about it.
3380 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3382 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3384 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3385 which defines C variables with global linkage.
3387 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3389 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3392 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3394 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3395 has time to check why this doesn't work well with continuations.
3397 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3399 * Fix shell syntax error; some shells won't tolerate
3400 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3402 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3404 * posix.c (scm_uname): throw an error if uname fails instead
3407 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3409 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3412 * async.c (scm_ints_disabled): definition moved from error.c.
3414 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3416 * acconfig.h: Removed PACKAGE.
3418 * scmconfig.h.in: Regenerated.
3420 * snarf.h: g++ says it's non-portable not to specify the first
3421 argument in a varargs declaration. I introduced the first
3422 argument by using preprocessor conditionals.
3424 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3426 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3427 (scm_freopen): use RO string macros for filename and modes.
3428 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3430 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3431 (scm_mknod): use RO string macros for path.
3433 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3434 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3436 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3437 use SCM_ROSTRINGP and SCM_ROCHARS.
3439 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3441 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3444 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3445 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3446 support for byte vectors.
3448 * print.c (scm_iprin1): Limit number of vector elements printed
3449 according to pstate->length.
3451 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3453 * backtrace.c (scm_display_error_message): don't segv if message
3456 * error.h: prototype for scm_error_scm.
3458 * error.c (scm_error_scm): new procedure, reimplements scm-error
3459 in C and uses scm_error.
3461 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3463 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3464 pointer to the Scheme variable read-hash-procedures and intern it
3465 in scm_init_read. Modify scm_read_hash_extend and
3466 scm_get_hash_procedure to use the pointer.
3468 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3470 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3471 (SCM_KEYWORD_STYLE): defined.
3473 * read.c (scm_read_opts): add a keywords option. This isn't a
3474 boolean option, in case someone wants to add support for DSSSL
3476 Setup scm_keyword_prefix symbol.
3477 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3479 I've left keyword support disabled by default, since it doesn't
3480 seem to break the module system and it gives R4RS standard behaviour.
3481 It can be reactivated with (read-set! keywords 'prefix).
3483 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3485 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3486 before constructing arbiter.
3488 * eval.c (scm_m_define): Bugfix: Check that the object is a
3489 closure before setting the procedure property!
3491 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3493 * ports.c: Removed `ungetc-char-ready?'.
3495 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3497 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3498 (idea from Mikael: make it a pair so scm_permanent object only
3500 (scm_read_hash_extend): don't call scm_permanent_object.
3501 (ideas from Mikael): if chr is already in the list, replace its
3502 procedure instead of appending it again. If proc is #f, remove
3504 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3506 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3508 * gdbint.c (gdb_read): update scm_lreadr usage.
3510 * load.h: update prototypes.
3512 * load.c (scm_primitive_load, scm_read_and_eval_x,
3513 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3515 * read.h: add prototype for scm_read_hash_extend. Change args for
3518 * read.c (scm_read_hash_procedures): new variable.
3519 (scm_read_hash_extend): new procedure.
3520 (scm_get_hash_procedure): new procedure.
3521 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3522 for extended # processing.
3523 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3524 scm_read_token): remove case_i, sharp arguments. Change callers.
3526 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3528 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3529 (SCM_CASE_INSENSITIVE_P): define.
3531 * read.c: add case-insensitive option to scm_read_opts.
3532 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3533 to determine whether to convert symbol case.
3534 (default_case_i): definition removed.
3535 * read.c (scm_read_token): if case_i, downcase ic before doing
3538 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * configure.in: Added configuration option `guile-debug'.
3541 Configure with --enable-guile-debug if you want a bunch of extra
3542 functions used for debugging when developing Guile.
3544 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3546 * procs.c (make-cclo): New undocumented debugging procedure: Make
3547 compiled closure with internal procedure PROC and length LENGTH.
3548 Only compiled if GUILE_DEBUG is defined.
3550 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3552 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3554 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3556 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3557 with 3 or more args internally to the evaluator.
3559 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3561 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3562 with 3 or more args internally to the evaluator. This is mainly
3563 because we don't want to pass entry and exit points of the
3564 debug support twice, but it also seems to increase the speed of
3565 the evaluator for such calls (e. g. (+ 1 2 3)).
3567 * backtrace.c (scm_display_application): New procedure:
3568 display-application; Set fancy printing parameters individually
3569 for different types of display (backtrace, error, application).
3570 (These should of course be customizable!)
3572 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3573 clear the CHECK-flags.
3575 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3577 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3579 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3581 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3582 from pairs with a GLOC in the car.
3584 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3585 otherwise `symbol-hash' will behave badly.
3586 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3587 we get segmentation fault!
3589 * symbols.c: Added #include "weaks.h". New functions:
3590 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3591 moved to an extraneous library when we split libguile.)
3593 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3595 * filesys.c (scm_stat): stat now takes fport arguments too as
3596 documented in the manual.
3598 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3600 * debug.c (scm_single_step): Bugfix: Call continuation with
3601 scm_call_continuation instead of throwing to it.
3603 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3605 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3606 argument wasn't declared to be optional.
3608 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3610 * stime.c (scm_init_stime): Add feature "current-time".
3612 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3614 * throw.h: prototype for scm_exit_status.
3615 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3616 args to derive an exit status. Allows (quit) to work from a
3618 (scm_exit_status): new function.
3621 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3623 * eval.c (scm_deval): Removed some old code.
3624 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3626 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3629 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3632 * procs.c: Introduce the existent C function scm_thunk_p at the
3633 Scheme level as well.
3635 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3637 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3638 used from C to easily lookup the value of a symbol in the current
3641 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3643 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3644 scm_init_unif in this file. This will also fix a previous problem
3647 * configure.in: Added AM_MAINTAINER_MODE
3649 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3651 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3654 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3656 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3657 source files that are not always included in libguile but should
3658 have their dependencies calculated by automake. This variable is
3659 recognized by automake, no further magic is needed.
3660 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3661 to deal exclusively with *.lo files, as it seems. The *.o files
3662 are built automatically when the corresponding *.lo file gets
3665 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3667 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3670 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3672 * unif.c (scm_array_set_x): minor change to argument error checking.
3674 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3676 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3677 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3678 They should only be included in the library at configure.in's
3680 (libguile_la_LDADD): Include the appropriate .lo files here.
3681 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3682 so we know when to build them (and their .lo bretheren).
3683 * configure.in (LIBLOBJS): New substituted variable. We let
3684 configure decide which .o files to include in LIBOBJS, and then
3685 put the corresponding list of .lo files in LIBLOBJS. The latter
3686 is what we pass to libtool.
3687 * Makefile.in, configure: regenerated.
3689 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3691 * symbols.c (scm_sysintern0): New function. Contains the core of
3692 old scm_sysintern but doesn't take a second value argument.
3693 (scm_sysintern): Now uses scm_sysintern0.
3694 (scm_sysintern_no_module_lookup): Renamed to
3695 scm_sysintern0_no_module_lookup and doesn't take a second value
3696 argument any longer.
3698 * symbols.h (scm_sysintern0: Added declaration.
3700 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3701 scm_sysintern when interning option keys. Otherwise we risk
3702 destroying the values of already interned variables.
3704 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3705 scheme-level boolean (use SCM_NFALSEP).
3707 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3709 (scm_backtrace): New function. (C version of old function from
3710 boot-9.scm) Motivation: Make it possible to display backtraces
3711 without depending on boot-9.scm. (I'm uncertain if this
3712 motivation is good enough...)
3714 * root.h (scm_root_state): Add member the_last_stack_var.
3715 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3717 * root.c (mark_root): Mark scm_the_last_stack_var.
3719 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3722 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3724 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3725 1. mark_lazy_catch didn't mark the smob.
3726 2. Both functions above have standard variants:
3727 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3728 free_lazy_catch --> scm_free0.
3730 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3732 * throw.c (scm_internal_lazy_catch): New function.
3733 (scm_lazy_catch): Rewritten to use it.
3734 (scm_ithrow): Handle the new lazy catch representation.
3735 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3736 that doesn't have a jmpbuf is a lazy catch clause.
3737 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3738 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3739 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3741 (scm_init_throw): Register the new lazy-catch smob type.
3742 * throw.h (scm_internal_lazy_catch): decl for new function.
3744 * throw.c (scm_internal_catch): Doc fixes.
3746 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3747 configure.in. Including this might cause problems if applications
3748 that link against libguile include their own copies of alloca, but
3749 if they're using autoconf, they should be adding libguile to LIBS
3750 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3751 the copy in libguile, and things will be okay. (I think.)
3753 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3755 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3757 strop.h: move prototypes too.
3759 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3761 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3764 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3765 etc. I deleted them from filesys.c long ago, but didn't
3766 notice they were here too (although ineffective since
3767 sys/stat.h wasn't included).
3769 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3771 * eval.c: Don't define alloca in GCC case. gcc will automatically
3772 use __builtin_alloca if appropriate.
3774 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3776 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3777 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3778 that values of automatic variables are preserved. See comments
3779 for safe_setjmp for details.
3781 Change from Thomas Morgan:
3782 * variable.c: Include eq.h.
3783 (var_equal): New function.
3784 (variable_smob): Use var_equal as the discriminator for variables.
3786 * throw.c (s_throw): Remove extraneous declaration.
3788 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3789 * eval.c: Add necessary CPP cruft to support that.
3790 * configure, Makefile.in, scmconfig.h.in: regenerated.
3792 Change from Thomas Morgan:
3793 * procprop.c (scm_procedure_properties): Convert the Scheme
3794 boolean returned by scm_procedure_p into a C boolean before using
3795 it as a condition for SCM_ASSERT.
3796 (scm_procedure_property): Likewise.
3798 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3799 indications of Unixness.
3802 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3804 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3806 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3808 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3809 "unknown # object" error messages.
3811 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3812 (scm_i_index) and declare it static. Add a 'direction' argument
3813 to indicate what way the search should go.
3814 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3816 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3817 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3819 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3821 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3823 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3824 to avoid clash with various scsh forks.
3826 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3828 The following two changes (ramap.c, throw.c) are motivated by the
3829 apparent unportability of forward declarations of static arrays of
3830 the form `static foo bar[];'.
3832 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3833 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3835 * throw.c (scm_throw): Moved above scm_ithrow.
3837 * options.h: Removed the extern declarations of scm_yes_sym and
3838 scm_no_sym since these are static.
3840 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3842 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3844 * Makefile.am: remove AWK=@AWK@.
3845 Add a rule for generating errnos.list.
3846 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3848 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3849 don't extract errnos, just set a variable (avoids the
3850 need to recompile error.c just because configure is run.)
3852 * unif.h: update prototypes.
3853 * unif.c (scm_uniform_array_read,write): change the offset and
3854 length arguments to start and end, for consistency.
3856 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3858 * ioext.h: update prototypes.
3859 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3860 scm_read_line_x, it's a more general procedure using an
3861 interface from scsh. read-line and read-line! are now defined
3863 Note that the new read-line trims the terminator
3864 by default, previously it was appended to the returned string. An
3865 optional argument specifies how to process the terminator (scsh
3866 compatible). For the old behaviour: (read-line port 'concat).
3867 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3868 returns a pair, but is converted to multiple values if the scsh
3871 socket.h: update prototypes.
3872 * socket.c (scm_recvfrom): for consistency with other procedures,
3873 take start and end as separate optional arguments.
3874 (scm_recv, scm_recvfrom): don't allow the second argument
3875 to be a size, only a buffer. Change the scheme names to
3876 recv! and recvfrom!. Don't return the buffer.
3878 * ioext.h, posix.h: move prototypes too.
3879 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3880 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3881 "read.h" and "unif.h".
3882 * ioext.c: include "chars.h"
3884 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3886 * dynl.c: The dynamic linking and module registration functions
3887 are now defined even when dynamic linking is not available for the
3888 host system. Some of their functionality can be done without
3889 dynamic linking; when it's really needed, they throw errors.
3891 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3893 * configure.in: Only define DYNAMIC_LINKING when one of the system
3894 dependent functions is detected.
3895 * dynl.c (scm_dynamic_func): New function to get the address of a
3896 function in a dynamic object.
3897 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3898 produced by scm_dynamic_func as the thing to call.
3900 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3902 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3903 (scm_register_module_xxx, scm_registered_modules,
3904 scm_clear_registered_modules): New functions.
3906 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3908 * symbols.c (scm_sysintern): Renamed to
3909 scm_sysintern_no_module_lookup.
3910 (scm_sysintern): New function to take the place of the old
3911 scm_sysintern. It uses the current toplevel lookup closure to give
3912 the symbol its value. This is a temporary hack to put packages
3913 like gtcltk into their own module.
3914 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3915 us whether `scm_top_level_lookup_closure_var' has been initialized
3917 * eval.c (scm_init_eval): Set it.
3919 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3921 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3922 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3924 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3926 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3927 scm_sys_dup): deleted: FD capability will be added to other
3929 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3930 scm_fd_free, fd_smob, scm_intern_fd.
3931 (scm_open): renamed from scm_sys_open. Return a port instead of
3932 an FD object. Make the mode argument optional.
3933 (scm_sys_create): deleted, it's just a special case of open.
3934 (scm_init_filesys): move interning of constants O_CREAT etc.,
3935 here (were previously using SCM_CONST_LONG macro).
3936 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3938 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3939 include "fports.h" and <stdio.h>
3940 (scm_stat, scm_select): don't support FD objects.
3942 * error.h: adjust scm_syserror_msg prototype.
3943 * error.c (scm_syserror_msg): take an extra argument for errno.
3944 Using the global value didn't always work, since it could be
3945 reset by procedure calls in the message or args arguments.
3947 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3948 I don't understand why the check was there (and what about the
3951 * strop.c (scm_string_copy): allow shared substrings to be copied.
3953 * unif.h: corresponding change to prototypes.
3954 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3955 recognize two new optional arguments: offset and length. Allow
3956 the port argument to be an integer (file descriptor, for scsh).
3957 Include <unistd.h> for "read" prototype.
3959 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3961 * socket.c: don't include filesys.h.
3963 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3965 * Makefile.am: add AWK=@AWK@ (?)
3967 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3969 Add a rule to generate errnos.c from errnos.
3970 * error.c (scm_init_error): include errnos.c.
3971 * errnos_cnvt.awk: new file, converts the list of errno codes to
3973 * errnos_get.c: new file.
3974 * errnos.default: new file, contains errnos to try if they can't
3975 be extracted from errno.h.
3976 * configure.in: if using GCC, try and extract errno codes from
3980 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3982 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3983 * Makefile.am: Made libguile into a libtool library.
3984 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3985 Set libtool_libs to indicate that libguile is a libtool library.
3986 See guile/ChangeLog for details.
3987 * .cvsignore: ignore "*.lo", the libtool library objects.
3989 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3991 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3992 use htons in getservbyport argument.
3994 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3996 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3997 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
4000 * objprop.c (scm_object_property): No need to take the CDR of the
4001 value returned by scm_object_properties, since Aug 20 change.
4003 * configure.in: When checking for struct linger, #include
4004 <sys/types.h> as well as <sys/socket.h>. I've never known
4005 <sys/types.h> to cause any portability problems, and Solaris's
4006 <sys/socket.h> needs it.
4007 * configure: Rebuilt.
4009 I think the Sun compiler has chosen a perverse way to interpret
4010 ANSI declarations combined with K&R definitions. We'll
4011 appease it a little bit. But when it invades France, we fight.
4012 * print.c (scm_iprlist): Change 'tlr' argument to an int.
4013 * print.h (scm_iprlist): Here too.
4014 * numbers.c (scm_divbigdig): Change definition to match
4015 declaration in numbers.h.
4016 * unif.c (scm_makflo): Change definition to match declaration in
4019 * init.c (scm_boot_guile): Don't return the value of
4020 scm_boot_guile_1. This function doesn't return a value;
4021 scm_boot_guile_1 doesn't return a value (or return at all).
4023 * eval.c (unmemocopy): Add a semicolon to appease the Sun
4026 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
4027 compile. I have a feeling this function is a bad idea anyway ---
4028 one should always test for features, not systems.
4030 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
4031 semicolons. Only pure luck kept this from being noticed earlier.
4033 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
4035 * socket.c (scm_recvfrom): Added missing semicolon.
4037 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4039 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
4040 the buffer and start and end positions for scsh networking
4043 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
4045 * configure.in: Revert previous change to this file; the problem
4046 is due to transient automake weirdness.
4047 * configure: Rebuilt.
4049 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
4050 PLUGIN/guile.libs. configure generates the latter from the former.
4051 * Makefile.in: Rebuilt.
4053 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
4054 need this if we install scripts, like guile-snarf.
4055 * configure: Rebuilt.
4057 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4059 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
4061 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
4063 * socket.c (scm_addr_vector): fix faulty scm_listify.
4065 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
4067 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
4068 style block comment is no longer considered an error.
4070 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4072 * PLUGIN/guile.libs.in: New file.
4073 * PLUGIN/guile.libs: Removed from repository.
4074 * configure.in: Create PLUGIN/guile.libs from
4075 PLUGIN/guile.libs.in. This is for including additonal libraries
4076 needed for dynamic linking.
4077 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4078 instead of PLUGIN/guile.libs.
4080 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4082 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4084 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4085 occurrences of the given element from the list, not just the
4086 first. This is how the Emacs Lisp functions behave, how the
4087 analogous Common Lisp functions behave, and (I believe) how the
4088 older Maclisp functions worked. I realize that this change may
4089 break code, but it seemed better to break it before the Guile
4092 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4093 Their prototypes were already present in gc.h, but they weren't
4095 (scm_init_storage): Initialize scm_protects.
4096 * root.c (scm_protects): New element of scm_sys_protects.
4098 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4100 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4102 * libguile.h: Added #include "libguile/net_db.h".
4104 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4105 30 change. That file is only meant for communication between the
4106 configuration process and load.c. If code linked against libguile
4107 wants to get at the paths mentioned in libpath.h, it can call
4108 functions declared in load.h.
4110 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4112 * libguile.h: Removed #include "libguile/fdsocket.h"
4114 * net_db.c: Added #include <sys/socket.h>.
4116 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4118 * filesys.c (scm_input_waiting_p): use select in preference to
4119 FIONREAD, since the latter doesn't detect EOF.
4120 Throw error if neither select nor FIONREAD available.
4122 * socket.c (scm_connect): take a port, not a fd object.
4123 (scm_fill_sockaddr): throw an error if fam is not recognised.
4124 (scm_bind): use scm_fill_sockaddr.
4125 (scm_listen): take a port, not a fd object.
4126 (scm_accept): take and return a port. return #f in the car if
4127 address can't be got
4128 (scm_sock_fd_to_port): new procedure.
4129 (scm_socket): use scm_sock_fd_to_port.
4130 (scm_addr_vector): throw error if unrecognised address type.
4131 take an extra argument with the calling procedure name.
4132 (scm_getsockname): take a port. return #f if address can't be got.
4133 (scm_getpeername): take a port. return #f if address can't be got.
4134 (scm_recvfrom): take a port. return #f for address component if can't
4136 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4137 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4139 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4141 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4142 use separate data pointers, to allow them to be designed
4143 independently and reused.
4144 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4145 Renamed from catch_body, catch_handler, and uncaught_throw; made
4147 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4149 (scm_catch): Use the above.
4150 (scm_throw): Don't bother printing a message for an uncaught
4151 throw; we establish a default handler in init.
4152 * throw.h (scm_internal_catch): Prototype updated.
4153 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4155 (struct scm_body_thunk_data): New structure, used as data
4156 argument to scm_body_thunk.
4157 * init.c (struct main_func_closure): New structure, packaging up
4158 the data to pass to the user's main function.
4159 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4160 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4161 scm_internal_catch to establish a catch-all handler, using
4162 scm_handle_by_message. This replaces the special-case code in
4164 (invoke_main_func): Body function for scm_internal_catch; invoke
4165 the user's main function, using the main_func_closure pointer to
4166 decide what to pass it.
4167 * root.c (struct cwdr_body_data): Remove handler_proc member.
4168 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4169 (cwdr_handler): Removed.
4171 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4173 * socket.h (SCM_P): update bind prototype.
4174 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4175 include "feature.h".
4176 (scm_socket): return a port, not a file descriptor object.
4177 include "fports.h" and <unistd.h>
4178 (scm_bind): take a port, not a file descriptor object.
4179 take an extra argument for address args.
4181 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4182 INADDR_NONE, INADDR_LOOPBACK.
4184 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4186 * init.c: include net_db.h and not fdsocket.h.
4187 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4189 * Makefile.am: corresponding changes.
4190 * socket.h: renamed from fdsocket.h, fix names.
4191 * net_db.h: renamed from socket.h, fix names.
4192 * socket.c: renamed from fdsocket.c.
4193 remove _sys from procedure names.
4194 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4195 add "socket" to features list.
4196 * net_db.c: renamed from socket.c.
4197 remove _sys from procedure names.
4198 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4199 add "net-db" to features list.
4200 include "net_db.h". don't include <sys/socket.h> or
4203 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4205 * tags.h (scm_tags): Removed comma at end of last enumerator.
4207 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4209 Don't use GCC extensions to allocate space for debugging frames.
4210 (Here he goes again! Why do we put up with this?!)
4211 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4212 an scm_debug_info structure, not an in-line array of them. Add
4213 'info' member, to say how many vect elements we've used, for eval
4215 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4216 a new variable debug_info_end to mark the end of vect, instead of
4217 the address of the 'info' pointer itself.
4218 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4219 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4220 (SCM_APPLY): Explicitly allocate space for debug.vect.
4221 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4222 * stacks.c: Adjusted for new debug frame structure.
4223 (RELOC_INFO, RELOC_FRAME): New macros.
4224 (stack_depth, read_frames): Use them, and new scm_debug_frame
4225 element 'info', instead of magically knowing that eval frames have
4226 an info pointer sitting after vect.
4227 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4229 (scm_init_stacks): Formatting tweaks.
4231 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4233 Give GCC more control flow information, so it can be sure that
4234 variables aren't used uninitialized.
4235 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4236 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4237 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4238 scm_misc_error): Tell GCC that these functions never return.
4239 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4240 out the field type, call abort if SCM_ASSERT returns, to placate
4242 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4243 scm_wta ever returns. We can't handle this case anyway, and this
4244 gives the optimizer more information.
4245 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4246 scm_wta ever returns.
4248 In some cases, the code is fine, but GCC isn't smart enough to
4249 figure that out; this usually happens when one variable is only
4250 initialized and used when a particular condition holds true, and
4251 we know that condition will never change within a given invocation
4252 of the function. In this case, we simply initialize the variables
4253 to placate the compiler, hopefully to a value which will cause a
4254 crash if it is ever actually used.
4255 * print.c (scm_iprin1): Initialize mw_pos.
4256 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4257 * throw.c (scm_ithrow): Initialize dynpair.
4258 * unif.c (scm_uniform_vector_ref): Initialize cra.
4259 * struct.c (init_struct): Initialize prot.
4260 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4262 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4263 if EXPR contains no expressions.
4265 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4267 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4268 cause an infinite loop (???). So much for the algebraic
4269 equivalency of variable-sized arrays and alloca...
4271 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4273 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4274 a SCM boolean, not a C boolean.
4276 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4278 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4279 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4280 rules for raising scm_mtrigger. Previously, unfortunate but not
4281 unlikely circumstances could result in almost constant invokation
4282 of the gc. Now, this situations should be less likely, but they
4283 are not prevented completely.
4285 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4287 * numbers.c (scm_fuck): Procedure removed; looks like old test
4289 * numbers.h: Prototype removed.
4291 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4293 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4294 array to a pointer, to match my Nov 21 change in eval.c.
4296 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4298 * libguile.h: Added #include "libguile/backtrace.h", #include
4299 "libguile/stacks.h".
4301 * strings.c (scm_string scm_make_string scm_string_ref
4302 scm_string_set_x scm_string_equal_p scm_string_append):
4303 Bugfix according to scm patch from Aubrey Jaffer:
4304 Corrected long-standing
4305 (not (eqv? (integer->char 128)
4306 (string-ref (make-string 1 (integer->char 128)) 0)))
4307 bug found by John Kozak <jk@noontide.demon.co.uk>.
4309 * strports.c, strports.h: Make scm_eval_0str return the value of
4310 the last expression evaluated (previously, it returned void).
4312 * strports.c, strports.h: New function: scm_read_0str. Does what
4315 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4317 * simpos.c (scm_getenv): return #f if string can't be found in the
4318 environment instead of throwing an exception, for compatibility
4319 with numerous other systems.
4321 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4323 * Makefile.am (.c.x): Use guile-snarf.
4324 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4326 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4328 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4330 * backtrace.c (scm_display_error_message): Made non-static, and
4331 renamed from display_error_message.
4332 * backtrace.h (scm_display_error_message): Added extern decl.
4333 * throw.c (uncaught_throw): Use it to display the error message.
4335 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4337 * inet_aton.c: Use #if 0, not #ifdef 0.
4339 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4341 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4342 to convert the returned value.
4343 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4344 the offset argument.
4346 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4348 Add new interface to catch/throw, usable from C as well as
4350 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4351 (scm_internal_catch): New function, replaces...
4352 (scm_catch_apply): Deleted.
4353 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4354 mechanism which is a bit more code, but can be used nicely from C
4355 and implement the Scheme semantics as well.
4356 (scm_internal_catch): This is the replacement; it's named after
4357 the analogous function in Emacs.
4358 (scm_catch): Reimplemented in terms of the above.
4359 (struct catch_body_data, catch_body, catch_handler): New
4360 functions, used by scm_catch.
4361 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4362 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4363 support for new cwdr.
4365 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4368 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4370 * acconfig.h: Added DYNAMIC_LINKING symbol.
4371 * configure.in: Add option and checks for dynamic linking.
4372 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4373 dynl.h: New files for dynamic linking support.
4374 * Makefile.am (libguile_a_SOURCES):
4376 (modinclude_HEADERS): Added "dynl.h".
4377 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4379 * init.c (scm_boot_guile_1): Call
4380 scm_init_dynamic_linking to initialize dynamic linking support.
4382 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4384 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4385 (as we Schemers say). It needs to be global, so that I can tweak
4386 it for the proper operation of unexec.
4387 (scm_boot_guile_1_live): New variable, see above.
4389 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4391 * guile-snarf.sh: Removed.
4392 * PLUGIN/guile.libs: Added dependency for -lm.
4393 * acinclude.m4: Renamed from aclocal.m4.
4394 * PLUGIN/greet: Removed.
4395 * Makefile.am, aclocal.m4: New files.
4396 * configure.in: Updated for Automake.
4398 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4400 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4401 and not top_level_lookup_thunk_var.
4403 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4405 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4407 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4409 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4410 Scheme function, instead of syntax. Single argument is now a
4413 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4415 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4416 scm_ra_divide): Properly terminate statements passed as arguments
4417 to IVDEP macros. (Thanks to Bernard Urban.)
4419 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4420 with non-constant sizes. (Thanks to Bernard Urban.)
4422 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4424 It's an "eval closure", not an "eval thunk." A thunk is a
4425 function of no arguments.
4426 * root.h (struct scm_root_state): Renamed
4427 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4428 (scm_top_level_lookup_closure_var): Renamed from
4429 scm_top_level_lookup_thunk_var.
4430 * root.c (mark_root): Uses changed.
4431 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4432 * init.c (scm_start_stack): Uses changed.
4433 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4434 Change scheme-visible name to *top-level-lookup-closure* from
4435 *top-level-lookup-thunk*.
4437 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4439 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4440 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4442 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4444 * gc.c (struct scm_heap_seg_data): Doc fixes.
4446 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4447 sweeping. Then, prepend each segment's free cells to its
4448 freelist, rather than wiping out the old value. (Thanks to Marius
4451 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4452 scm_check_freelist, scm_debug_newcell): New functions and
4453 variables, for debugging freelist problems.
4454 * pairs.h (SCM_NEWCELL): New debugging version added.
4455 * gc.h (scm_debug_newcell): Added extern declaration, used by
4456 debugging version of SCM_NEWCELL.
4458 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4460 On some systems <libc.h> conflicts with <unistd.h>, and should not
4461 be #included at all.
4462 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4463 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4464 * configure.in: Call it.
4465 * posix.c, filesys.c: Use its results to decide whether or not to
4467 * configure, scmconfig.h.in: Rebuilt with autoconf and
4470 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4472 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4473 pointer to the stdio stream before calling scm_setbuf0, so the
4474 latter will be able to retrieve it. I'm surprised this didn't
4475 segfault earlier. (Thanks to Christopher Lee.)
4477 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4479 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4482 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4484 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4485 number of stack narrowing specifier pairs. The first specifier in
4486 a pair controls inner border, the second the outer border. A
4487 number means cut that number of frames, a procedure object means
4488 cut until that object is found in operator position in a frame.
4490 * root.c (cwdr): Bugfix.
4492 * read.c: Recording of positions disabled by default.
4494 * procs.c (scm_closure_p): New function.
4496 * posix.c (scm_tmpnam): New function.
4498 * load.c: Added #include "throw.h".
4499 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4502 * load.c, load.h (scm_read_and_eval_x): New function.
4504 * eval.c: Renamed debug option "deval" to "debug".
4506 (scm_eval_x): `eval!' is no longer accessible from the scheme
4507 level. Motivation: We can't allow operations which introduce
4508 glocs into the scheme level. Guile's type system can't handle
4509 these as data. Use `eval' or `read-and-eval!' as replacement.
4511 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4512 SCM_CONSP since this is a macro!; Set vframe.prev to
4513 scm_last_debug_frame instead of 0. In this way we can look
4514 "above" the virtual start stack frame if we wish.
4515 (scm_debug_hang): New function: Useful for debugging Guile in
4516 certain tricky situations. Will probably be removed later...
4518 * debug.h: Changed semantics of debug option "backtrace". This
4519 option now only indicates whether we want automatic backtrace at
4522 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4524 * ports.c: #include "filesys.h"
4525 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4527 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4528 Motivation: This is system specific code which is related to file
4529 I/O. It also may use select. Added code by Gary Houston to
4530 detect presence of character in stdio buffers.
4532 * libguile.h: #include "libguile/libpath.h"
4534 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4535 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4536 SCM_SITE_DIR; Install libpath.h among the other include files.
4538 * load.c, load.h (scm_sys_package_data_dir): New function.
4540 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4542 * stacks.h: Bugfix: Don't use tail-array length field as stack
4543 length field! This screwed GC.
4545 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4547 * _scm.h: Added #ifndef around definition of macros min and max.
4549 * __scm.h: Added hooks for threads to plugin to in ints protection
4550 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4551 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4552 the main code in these macros duplicated and spread over multiple
4553 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4554 SCM_THREAD_SWITCHING_CODE.
4556 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4558 * snarf.h: New file.
4559 * guile-snarf.sh: New file.
4560 * Makefile.in (inner_h_files): Added snarf.h
4561 (ancillary, install, uninstall, distclean): Added actions for
4563 (.c.x): Use guile-snarf.
4564 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4565 (gen_c_files): Note that these depend on guile-snarf.
4566 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4567 now in "snarf.h". Added #include "snarf.h" to get them.
4568 * libguile.h: Added #include "snarf.h".
4569 (Patches applied and tweaked by Jim Blandy.)
4571 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4573 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4574 standards suggest against providing prototypes for system
4575 functions. Thanks to Greg Troxel.
4577 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4579 * strports.c (scm_eval_0str): New function.
4580 #include "read.h", to get prototype for scm_read.
4581 * Makefile.in (strports.o): Update dependencies.
4582 * strports.h: New prototype.
4584 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4585 scheme name from "int?" to "integer?". It seems to do the job.
4586 * numbers.h: Rename prototype too.
4587 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4590 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4591 scm_num_eq_p): Rename these according to R4RS conventions: call
4592 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4593 to making libguile R4RS compliant without ice-9...
4595 * load.c (scm_sys_search_load_path): Search for files under all
4596 extensions listed in the %load-extensions variable. If FILENAME
4597 is absolute, return it unchanged, without searching the load path.
4598 (scm_loc_load_extensions): New variable, pointing to
4599 %load-extensions' value cell.
4600 (scm_init_load): Initialize it, and the value it points to.
4601 (scm_primitive_load_path): Improve error reporting.
4603 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4604 of new Scheme variable %load-hook.
4605 (scm_primitive_load): Apply %load-hook to filename.
4607 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4609 * configure.in: add tests for figuring out whether buffered data
4610 is available in a FILE structure, which is needed by char-ready.
4612 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4615 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4616 exceptions using misc_error instead of syserror. It seems a bit
4617 odd to throw an exception if a string can't be found in the
4618 environment, but it's consistent with open-file, stat etc.
4619 (simpos.h): remove sys_ from getenv.
4621 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4622 occurs, throw an error instead of returning errno. Return value
4624 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4626 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4628 * filesys.c (scm_stat2scm): derive file type and permissions from
4629 the stat mode and append them to the returned vector.
4630 There isn't much overhead in doing this and it avoids the need to
4631 work with S_IRUSR et al. in Scheme.
4632 Define symbols scm_sym_regular etc.
4633 (scm_init_filesys): don't intern S_IRUSR etc.
4635 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4636 and s_primitive_load_path.
4638 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4640 * error.h: don't declare error symbols. prototype for scm_misc_error.
4642 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4645 * error.c: use SCM_SYMBOL to set up error keys.
4646 scm_misc_error: new procedure.
4648 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4650 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4651 between `#!' and `!#' is ignored.
4652 (skip_scsh_block_comment): New function.
4654 * feature.c (scm_set_program_arguments): New argument, FIRST.
4655 * feature.h: Update prototype.
4656 * init.c (scm_boot_guile_1): Pass new argument to
4657 scm_set_program_arguments.
4659 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4661 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4662 (scm_boot_guile): Call scm_set_program_arguments here, later than
4663 the old initialization.
4665 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4666 initialization procedure.
4667 - Delete in, out, err arguments; there are other perfectly good
4668 ways to override these when desired.
4669 - Delete result argument; this function shouldn't ever return.
4670 - Rename init_func argument to main_func, for less confusion.
4671 - Delete boot_cmd argument; main_func is more general.
4672 -Add 'closure' argument, to help people pass data to main_func
4673 without resorting to global variables.
4674 - Abort if reentered; don't bother returning an error code.
4675 - Call scm_init_standard_ports to set up the default/current
4676 standard ports; no need to pass them to scm_start_stack.
4677 - Remove code to evaluate the boot_cmd, and start the repl; let
4678 the user do something like that in main_func if they want.
4679 - Remove code to package up a return value; main_func can do any
4681 - Call exit (0), instead of returning.
4682 (scm_start_stack): Don't initialize the I/O ports here; that's
4683 weird. Delete in, out, err arguments. Move guts to
4684 scm_init_standard_ports, scm_stdio_to_port.
4685 (scm_init_standard_ports): New function, to set up current and
4686 default standard ports.
4687 (scm_start_stack, scm_restart_stack): Make these static.
4688 * init.h (scm_boot_guile): Adjust declaration.
4689 (scm_start_stack, scm_restart_stack): Remove externally
4690 visible declarations for these.
4691 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4693 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4694 written out several times in scm_start_stack.
4695 * fports.h: New declaration for the above.
4697 * feature.c (scm_set_program_arguments): New function.
4698 * feature.h: New declaration for the above.
4700 * ports.c: Formatting tweak.
4702 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4704 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4705 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4706 for obtaining the address of a car or cdr field. Motivation:
4707 &SCM_CXR make assumptions about the internal structure of the
4710 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4711 Motivation: see SCM_CXRLOC.
4713 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4714 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4715 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4716 Motivation: Safer use. Some other macros are defined in terms of
4717 these operations. If these are defined using the SCM_SETCXR
4718 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4719 to inefficiency and an <e1> with side-effects could potentially
4720 break. Also, these particular operations are heavily utilized in
4721 the garbage collector. In unoptimized code there will be a
4724 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4725 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4726 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4727 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4728 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4729 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4730 vports.c: Cleaned up use of pairs: Don't make any special
4731 assumptions about the internal structure of selectors and
4732 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4733 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4734 (Among other things, this change makes it easier to build Guile
4735 with certain compilers which have problems with casted lvalues.)
4737 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4739 * stacks.c: Improve selection of relevant stack frames when making
4740 a stack object. Introduce one level of indirection in the stack
4741 object to make it possible to "narrow" to a certain region of the
4742 stack. This facilitates making use of more clever algorithms (not
4743 implemented) for selecting relevant frames and gives a cleaner
4744 design since selection of frames can be done independently of
4745 extraction of frames from the real stack.
4746 (scm_stack_id): Also take #t as argument which means look at
4749 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4750 Turn n_tail into an integer directly representing current number
4751 of frames in stack. Add field tail.
4753 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4755 * debug.c (scm_make_memoized): Made it available at scheme level.
4756 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4757 SCM_NIMP before applying heavier predicates in argument checking.
4758 (scm_local_eval): Also take memoized object as argument.
4760 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4761 aren't created with zero length, but should such a strange
4762 creature suddenly turn up...
4764 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4766 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4767 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4769 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4771 * variable.c (scm_make_variable): Make the name hint optional, as
4773 (anonymous_variable_sym): Renamed from variable_sym. All uses
4776 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4777 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4778 of scm_primitive_load_path was also changed to
4779 "primitive-load-path", from "%try-load-path". Callers changed.
4780 We'd like to respect the convention that a function named
4781 "try-mumble" should behave just like the function called "mumble",
4782 but return #f instead of signalling some error.
4783 * load.h: Rename prototypes.
4785 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4787 * print.c (make_print_state, grow_print_state), print.h: Modified
4788 the print state representation: Don't use a tail array for
4789 recording of circular references. Resizing of the print state
4790 structure invalidates the print state pointer. To avoid passing
4791 around an indirect print state reference to all printing
4792 functions, we instead let the print state reference a resizable
4795 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4797 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4798 Don't crash when passed an improper list terminated by a
4799 non-immediate value.
4801 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4803 Allocate data for structures on an eight-byte boundary, as
4804 required by the tagging system.
4805 * struct.c (alloc_struct): New function.
4806 (scm_make_struct, scm_make_vtable_vtable): Call it.
4807 * struct.h (scm_struct_n_extra_words): Bump to 3.
4808 (scm_struct_i_ptr): New "field".
4809 * gc.c (scm_gc_sweep): When we need to free the data, use the
4810 information stored by alloc_struct to find the beginning of the
4811 block allocated to the structure, so we can free it.
4813 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4815 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4818 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4819 (scm_debug_info): New member: id.
4821 * stacks.c: Stacks are now represented as structs; Stacks have an
4822 id given to them by `start-stack'.
4823 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4825 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4826 Changed stack representation.
4828 * debug.c (scm_procedure_name): Try procedure property `name' for
4829 compiled closures aswell.
4831 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4833 * eval.c: scm_i_name moved to gsubr.c

4835 objects. (Earlier, only closures were recorded.)
4837 * procprop.h: Added declaration of scm_i_name.
4839 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4840 (scm_make_gsubr): Record names of compiled closures.
4842 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4844 * debug.c, debug.h: Removed obsolete code.
4846 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4847 stacks.c: Renamed regs --> scm_contregs.
4849 * print.c (scm_free_print_state): Cleanup print state before
4850 returning it to pool. It is better to do it here than in
4851 scm_prin1 since scm_prin1 is called often.
4853 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4854 s_set_source_property_x): Check that first argument is a pair or a
4857 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4858 scm_i_line, scm_i_column and scm_i_breakpoint global.
4860 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4861 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4864 * debug.h: Added debug object smob declaration and macro
4867 * configure.in: Build with backtrace.o and stacks.o if debug

4871 backtrace.h, stacks.c and stacks.h.
4873 * symbols.c (scm_sym2ovcell): Fixed documentation.
4875 * _scm.h (min, max): Added.
4877 * async.c: Moved `min' macro to _scm.h.
4879 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4880 SCM_BACKTRACE_INDENT.
4882 * eval.c: Added new debug options `maxdepth' and `indent'.
4884 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4886 * print.h: Added selector SCM_PRINT_STATE.
4888 * print.c: New functions: scm_make_print_state,
4889 scm_free_print_state.
4891 * print.h: Added declarations for scm_make_print_state,
4892 scm_free_print_state.
4894 * debug.c (scm_m_start_stack): New acro.
4896 * debug.h: Small cleanup.
4898 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4923 declare functions with prototypes. (Patch thanks to Marius
4926 More prototype-related changes from Marius Vollmer:
4927 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4928 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4929 * ports.h (ptobfuns): Added prototypes. This means some casting in
4931 * fports.c: Added casts for initializations, since the functions
4932 are defined to take FILE * as their stream argument, not SCM.
4933 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4934 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4935 to `char *str_data' to conform to prototype.
4937 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4939 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4941 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4943 * stime.c, stime.h: use SCM_P method.
4945 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4947 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4948 be given at least two arguments. Insist that lst's last element
4949 be a list, but don't make any requirements of its predecessors.
4951 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4953 * eval.c (scm_nconc2last): Revert last change; there seems to be
4954 other stuff going on here.
4956 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4958 * eval.c (scm_nconc2last): Make sure that each element of lst
4959 (which is a list of argument lists, except for the tail) is a
4960 proper list, i.e., finite and terminated by '().
4962 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4964 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4967 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4968 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4971 * vectors.c (scm_make_vector): Fill vectors with the undefined
4972 value, to help make Guile Scheme code more portable to other
4975 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4976 * symbols.h, tags.h: Doc fixes.
4978 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4980 * async.c (scm_take_signal): Doc fixes.
4982 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4984 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4985 want to subtract it from the modulus; we just want to leave it
4988 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4990 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4993 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4995 * throw.c (scm_catch_apply): Finished implementation of
4998 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5000 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
5002 (scm_init_filesys): set "i/o-extensions" feature.
5005 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
5007 * Makefile.in (root.o): Correct dependencies.
5009 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
5011 * Makefile.in: Added dependency entry for root.o.
5013 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
5014 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
5016 * init.c (scm_start_stack): Set initial root continuation number
5019 * procs.c: New function: scm_thunk_p.
5021 * procs.h: Added declarations of scm_thunk_p.
5023 * root.c: Renamed `call-with-new-root' -->
5024 `call-with-dynamic-root'.
5025 (cwdr): Removed allocation of new root state. This should be done
5026 separately by use of scm_make_root.
5027 (scm_apply_with_dynamic_root): New function: Does what it
5028 sounds like. Needed when spawning threads.
5030 * root.h: Added member last_debug_frame to root state.
5031 Added #include "libguile/debug.h"
5033 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
5034 arguments. The motivation is that code in root.c needs catch
5035 functionality, and we want to avoid code duplication.
5036 New functions: scm_catch, scm_lazy_catch. These are wrappers for
5037 scm_catch_apply. scm_lazy_catch is intended to introduce catch
5038 handlers that run without popping the stack into the dynwind
5041 * throw.h: Added prototypes for scm_catch_apply and
5044 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5046 * root.h (scm_root, scm_set_root): Decouple thread support details
5047 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
5048 SCM_SET_THREAD_LOCAL_DATA.
5050 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
5051 and tortoise scanning loop.
5053 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
5055 * Makefile.in: Rebuild dependencies.
5057 * libguile.h: #include "libguile/print.h" before "smob.h", since
5058 the latter uses the print_state structure.
5060 * throw.c (scm_ithrow): Use the correct variable when checking to
5061 see if a given element of scm_dynwinds is a valid catch.
5063 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
5064 structure, abort; don't just silently ignore the garbage.
5066 * _scm.h: #include "print.h" here, since it seems to be used just
5068 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
5069 strports.c, unif.h: Don't #include "print.h".
5071 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5073 * feature.h (scm_loc_features): Removed external declaration.
5074 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5076 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5078 * feature.c (scm_init_feature): Added threads feature (needs to be
5079 initialized here, since features doesn't exist when
5080 scm_init_threads is called).
5082 * libguile.h: Added #include "libguile/../threads/threads.h".
5083 (This is a kludge to get thread support working. This should be
5086 * configure.in, acconfig.h: Added flags for thread support.
5088 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5091 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5092 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5095 * _scm.h: Added conditional #include "threads.h"
5097 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5098 SCM_THREADS_SWITCHING_CODE.
5100 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5101 allocate the basic dynamic root object.
5102 (scm_boot_guile): Added call to scm_init_root.
5104 * root.c, root.h: Added root smob.
5105 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5106 functions: Implements dynamic roots mostly according to spec in
5107 SCM manual. Main difference is that the second argument is a
5108 throw handler rather than an error "thunk".
5110 * root.h: Added declaration of scm_init_root.
5112 * root.c: Added #include "genio.h", #include "smob.h", #include
5113 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5115 (scm_init_root): Added #include "root.x".
5117 * throw.c: Added #include "stackchk.h"
5118 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5119 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5120 can be used in scm_call_with_new_root; Added reenabling of stack
5121 checking when catching a throw.
5123 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5125 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5127 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5128 element is not found, as per R4RS.
5130 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5132 * list.c: Doc fixes throughout.
5134 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5136 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5137 declare the char * to be const. Avoids a warning in rgx.c.
5139 * ports.h: spelling fix.
5141 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5144 * load.c (scm_sys_try_load_path): throw an error if file not found
5145 (like it says it in NEWS).
5147 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5149 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5150 PROPS slot to '(), not #f; it's an empty alist.
5152 * throw.h, throw.c: Use SCM_P instead of #if hair.
5154 Remove special support for uncaught throws; see throw.c for
5156 * throw.c (uncaught_throw): New function.
5157 (scm_ithrow): Call uncaught_throw if we don't find a throw
5158 target; don't mess with scm_bad_throw_vcell.
5159 (scm_bad_throw_vcell): Variable deleted.
5160 (scm_init_throw): Don't initialize it.
5162 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5165 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5167 * numbers.c (scm_istr2int): If the number is short (as most
5168 numbers are), just call scm_small_istr2int to deal with it.
5169 (scm_small_istr2int): New function, created by un-#ifdefing the
5170 non-bignum version of scm_istr2int and renaming it.
5172 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5174 * load.c (scm_sys_try_load): don't check whether value returned
5175 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5176 Change the Scheme name from %try-load to primitive-load.
5178 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5179 Can avoid passing a message, allowing it to be derived in the
5180 error handler (e.g., if we want to throw to the key both from
5183 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5185 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5186 references now have a new appearance which is more compact and
5187 also gives a clue about what the target of the reference is.
5188 By setting parameters in the print state, more fancy printing can
5189 be achieved. This is used by the (not yet commited) backtrace
5192 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5194 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5197 * print.c: Added #include "struct.h". Removed function
5200 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5201 scm_iprin1. Removed prototype for scm_prlist.
5203 * arbiters.c (prinarb),
5204 async.c (print_async),
5205 debug.c (prindebugobj, prinmemoized),
5206 eval.c (prinprom, prinmacro),
5207 filesys.c (scm_fd_print, scm_dir_print),
5209 mallocs.c (prinmalloc),
5210 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5211 smob.h (scm_smobfuns),
5212 srcprop.c (prinsrcprops),
5214 unif.c, unif.h (scm_raprin1, rapr1),
5215 variable.c (prin_var): Changed argument `int writing' to
5216 `scm_print_state *pstate'.
5218 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5219 that it will be called before scm_init_print.
5221 * print.c (scm_prin1): Print states are now allocated when calling
5222 scm_prin1 and then passed around to all printing functions as an
5223 argument. A cache `print_state_pool' enables reuse of print
5225 (scm_make_print_state): New function.
5226 (scm_iprin1): Adaption to print states.
5227 (scm_iprlist): An initial "hare and tortoise" scan brings down
5228 time complexity to O (depth * N). (Better time complexity will be
5229 achieved when the printing code is completely rewritten.)
5231 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5233 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5234 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5235 it gets done whether or not the cache variable has a value.
5237 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5239 Distinguish #f and ().
5240 * __scm.h: #undef SICP.
5241 * pairs.h (SCM_EOL): Delete this definition, equating it with
5243 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5244 the value it used to have. Doc fixes, too.
5246 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5248 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5249 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5250 Lord's implementation of structs, allowing for tail arrays as
5251 described in the manual. Also fixed some bugs. (Both the interface
5252 and the implementation should be improved.)
5254 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5256 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5257 People who whish to see the source can do `(print-enable 'source)'.
5258 Removed #ifdef DEBUG_EXTENSIONS.
5260 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5262 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5263 integer (assuming for now accepting an integer is a good thing).
5265 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5266 %S will be used instead for write'ing arguments.
5268 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5269 asserts. fix a few other asserts.
5270 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5271 scm_uniform_vector_ref, scm_array_set_x,
5272 scm_dimensions_to_unform_array): change args in
5273 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5274 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5275 scm_substring_fill_x): likewise.
5276 gsubr.c (scm_gsubr_apply): likewise.
5277 eval.c (SCM_APPLY): likewise.
5279 * eval.c (4 places): replace scm_everr with lgh_error or
5282 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5283 scm_memory_error): new procedures.
5284 scm_everr: deleted. can use scm_wta, dropping first two args.
5285 scm_error: convert NULL subr to SCM_BOOL_F.
5287 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5290 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5293 * error.c, error.h: new error keys: scm_arg_type_key,
5294 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5296 scm_wta: reimplement using lgh_error instead of scm_everr.
5298 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5300 * gdbint.c: scm_lread now has one more argument.
5302 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5303 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5304 loading source from non-file ports, which, e. g., happens when
5305 using the Emacs interface).
5307 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5310 * read.c: Added code for recording of positions of source code
5311 expressions; New functions: recsexpr, scm_lreadrecparen;
5312 _scm_make_srcprops --> scm_make_srcprops
5313 (scm_flush_ws): Removed updating of positions counters. This work
5314 is already done by scm_gen_getc
5316 * read.h: Added prototype for scm_lreadrecparen
5318 * print.c: Added #include "alist.h"
5320 * eval.c: Added #include "hash.h"
5322 * eq.c: Added #include "ramap.h"
5324 * options.c: Documentation fixes.
5326 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5327 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5328 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5329 --> scm_make_srcprops
5331 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5332 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5333 function calls in the definition of the whash access macros.
5335 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5337 * init.c (scm_boot_guile): Add level of indirection to
5338 scm_boot_guile_1() to ensure that stack base pointer is properly
5339 initialized. There was no guarantee that variable i was the
5340 highest/lowest variable on stack (i.e. the call frame of
5341 scm_boot_guile was not completely protected from gc).
5343 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5345 * ports.h (scm_port_table): put back file_name, it will be used to
5346 support debugging. Undo related changes in fports.c, ioext.c,
5349 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5351 * ports.h (scm_port_table): remove file_name member for now, it seems
5353 * fports.c (scm_open_file): don't set file_name in PTAB.
5354 (prinfport): don't use file_name in PTAB.
5355 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5356 * ports.c (scm_add_to_port_table): don't intialize file_name.
5357 (scm_port_file_name): remove for now.
5358 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5360 * fports.h (scm_mkfile): prototype deleted.
5361 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5363 * debug.c, unif.c: use scm_out_of_range instead of
5364 wta for range errors (ASSERT still needs work).
5366 * error.c, error.h (scm_out_of_range): new procedure.
5368 * error.c, error.h (scm_out_of_range_key): new key.
5370 * posix.c (scm_sync): #else was missing.
5372 * error.c, error.h: append _key to names scm_num_overflow and
5375 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5376 of consing an empty list.
5377 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5378 of macros, saves code and string space.
5379 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5380 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5381 lower case. Rename scm_syserror_m to scm_syserror_msg.
5382 error.h: prototypes for new procedures.
5384 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5386 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5388 * error.c, error.h: setup scm_num_overflow key.
5390 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5391 Remove definition of SCM_OVSCM_FLOW.
5393 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5395 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5396 explicit message and args.
5398 * error.c, error.h, __scm.h: change system_error_sym to
5401 * error.c (system_error_sym): remove leading %% from the Scheme name
5404 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5406 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5408 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5409 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5410 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5411 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5412 renamed. (These were introduced by unsupervised name
5415 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5417 * print.c: Added code for detection of circular references during
5418 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5419 a hook for printing of closures (accessible via print options).
5420 This leads to a split of calls to scm_iprin1 into two classes:
5421 elementary print operations (e. g. the code which prints a smob)
5422 still use scm_iprin1 while top level calls (like scm_display) use
5423 scm_prin1. scm_prin1 begins by clearing the data structure used
5424 to record reference information.
5426 * print.h: Added declarations of scm_prin1 and scm_prlist.
5428 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5430 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5432 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5434 * error.c (err_head): scm_iprin1 --> scm_prin1
5436 * debug.c: Adjusted header comment.
5440 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5442 * strerror.c: Doc fix.
5444 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5446 * gdbint.c (gdb_read): Now possible to run during GC.
5447 (unmark_port, remark_port): New functions.
5449 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5451 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5452 of allocating a new string object. Also, increase size by
5453 the factor 2 instead of 1.5.
5455 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5457 * __scm.h (SCM_P): Corrected to run under traditional C.
5459 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5462 * async.c: Calls to scm_sysintern corrected.
5464 * async.h (scm_async_clock): Redundant declaration removed.
5466 * continuations.c (scm_dynthrow): Redundant declaration removed.
5468 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5469 Definition typos corrected.
5471 * debug.h: Missing declarations of functions in debug.c added
5474 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5475 Missing declarations to functions in eval.c added.
5477 * filesys.c: Possibly uninitialized variable rv.
5479 * gc.h (scm_object_addr, scm_unhash_name): Missing
5480 declarations of functions defined in gc.c added.
5482 * genio.c: Possible typos str_data -> wstr_data. ???
5484 * genio.c: Possibly unintended shadowing of local variable
5485 `int c' (gotos out of scope of inner `c'). ???
5487 * init.c: Uninitialized `SCM last' may be used.
5489 * ioext.h: (scm_sys_isatty_p): Typo.
5491 * list.h (scm_list_head): Missing prototype for function in
5494 * numbers.c (scm_two_doubles): Changed from extern to static
5495 (is used only within numbers.c).
5497 * numbers.h: Repeated declarations removed.
5499 * ports.h (scm_close_all_ports_except): Declaration for the
5500 function defined in ports.c added.
5502 * posix.h: Missing declarations added.
5504 * procs.h (scm_make_subr_opt): Missing declaration added.
5506 * socket.h (scm_sys_gethost): Missing declaration added.
5508 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5510 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5511 Missing declarations added.
5513 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5515 * struct.c: Uninitialized variable `SCM answer' may be used.
5517 * unif.c (l2ra): Declaration prototype.
5519 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5520 defined in ramap.c).
5522 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5523 Redundant declarations removed (they are in ramap.h).
5525 * variable.h (scm_make_udvariable,
5526 scm_make_undefined_variable): Declaration corrected to
5527 correspond variable.c.
5529 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5530 Missing declarations added.
5532 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5534 * Makefile.in (distclean): Don't forget to delete fd.h.
5536 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5538 * fd.h.in, tags.h: Trivial cleanups.
5540 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5541 marksweep.h just declared functions from gc.c.
5542 * gc.h, libguile.h: Don't #include "marksweep.h".
5543 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5544 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5545 dependencies updated.
5547 * libguile.h: Don't #include "files.h"; it's been deleted.
5549 * files.c (scm_sys_delete_file): Moved to filesys.c.
5550 File is now empty; deleted.
5552 * filesys.c: scm_sys_delete_file is now here. Remove
5553 #if's; they seem to rely on remnants of an old portability
5554 regimen. If the problems come up again, solve them properly,
5555 using autoconf. Specifically: Don't test M_SYSV, and #define
5556 remove to be unlink if it's #defined; don't use remove just
5557 because HAVE_STDC_HEADERS is #defined.
5558 * filesys.h: Add declarations for scm_sys_delete_file.
5559 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5560 files.o, files.h, files.c, and files.x.
5561 * init.c: Don't #include "files.h", and don't call scm_init_files.
5563 Use SCM_P instead of PROTO; the latter intrudes on the user's
5565 * params.h: Deleted; definition of SCM_P moved to...
5566 * __scm.h: ... here, where it replaces PROTO macro.
5567 * libguile.h, smob.h: Don't #include "params.h".
5568 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5569 smob.h: Fix prototypes accordingly.
5570 * Makefile.in: Update dependencies.
5571 (inner_h_files): Remove params.h.
5573 * gc.c: #include "gc.h"; every module should include its header,
5574 to let the compiler cross-check the declarations against the
5577 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5578 simpos.h: #include "libguile/__scm.h".
5580 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5582 * init.c: Don't forget to #include smob.h and init.h.
5583 * Makefile.in: Dependencies updated.
5585 * smob.h: Use PROTO instead of #if __STDC__.
5587 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5589 * __scm.h: Doc fixes.
5591 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5592 <angles>; this allows `make depends' to work properly.
5594 * libguile.h: #include smob.h and pairs.h before the others; they
5595 define typedefs used by other headers.
5597 C files should #include only the header files they need, not
5598 libguile.h (which #includes all the header files); the pointless
5599 recompilation was wasting my time.
5600 * Makefile.in (all .o dependency lists): Regenerated.
5601 * libguile.h: Don't try to get a definition for size_t here...
5602 * __scm.h: Do it here.
5603 * _scm.h: Since this is the internal libguile header, put things
5604 here that all (or a majority) of the libguile files will want.
5605 Don't #include <libguile.h> here; that generates dependencies on
5606 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5607 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5608 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5705 * weaks.c: Get "weaks.h".
5707 * stackchk.h: #include "libguile/debug.h",
5709 * print.h, read.h: #include "options.h", since everyone who uses
5710 either of these files will need that.
5712 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5713 anyone who uses this file will need them to define the smob
5714 printing functions. Also, get markers.h, since people will need
5715 to #define the mark functions.
5717 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5718 * ports.h: ... to here.
5720 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5721 don't rely on archaic C default type rules.
5723 * fports.h: #include "libguile/ports.h", since you need that in
5724 order to parse this.
5726 * genio.h: #include "libguile/print.h", because you need that to
5727 parse this; don't bother #including "ports.h", since print.h gets
5730 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5732 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5733 this; it's now a reference to an element of *scm_root.
5735 * debug.h: Don't #include "options.h"; the compiler won't be able
5736 to find that once the headers are installed; instead, #include
5737 "libguile/options.h".
5738 * gc.h: Same, with marksweep.h.
5739 * mbstrings.h: Same, with symbols.h.
5740 * scmhob.h: Same, with _scm.h.
5741 * smob.h: Same, with params.h.
5743 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5744 C files; there's no need for this, and it forces recompilations
5747 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5749 * error.c (scm_error): declare scm_error_callback.
5751 * error.h: prototype for scm_error_callback.
5753 * __scm.h: define lgh_error.
5754 (SCM_SYSERROR): redefine using lgh_error.
5756 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5758 * error.c (scm_error): new procedure.
5760 * error.h: prototype for scm_error.
5762 * Makefile.in (install): install scmconfig.h from the current
5763 directory, not $(srcdir).

5778 dependencies are within libguile properly.
5780 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5782 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5783 when scmconfig.h doesn't exist.
5785 * load.c (scm_sys_try_load): Correct spelling.
5787 * feature.c (scm_loc_features): Make this static.
5789 * Makefile.in (libpath.h): Omit trailing slash from path. We
5790 shouldn't require it of users, so why put it here?
5792 Move code to initialize and search %load-path from ice-9 to C
5793 code, so we can use the load-path to find the ice-9 boot code;
5794 this makes it easier to run Guile without installing it. See
5795 corresponding changes in guile/Makefile.in.
5796 * feature.c: Move stuff concerned with the load path to load.c.
5797 (scm_compiled_library_path): Deleted.
5798 Don't #include libpath.h here.
5799 * feature.h: Don't mention scm_compiled_library_path.
5800 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5801 <sys/stat.h>, and <unistd.h> (if present).
5802 (R_OK): #define if the system hasn't deigned to.
5803 (scm_loc_load_path): New variable.
5804 (scm_init_load_path, scm_sys_search_load_path,
5805 scm_sys_try_load_path): New functions.
5806 (scm_init_load): Initialize scm_loc_load_path to point to the
5807 value cell of the Scheme %load-path variable.
5808 * load.h: Add declarations for scm_sys_search_load_path,
5809 scm_sys_try_load_path.
5810 * init.c: Call scm_init_load_path.
5811 * Makefile.in (feature.o, load.o): Dependencies updated.
5813 * load.c, load.h: Rewrite using PROTO macro.
5815 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5817 * gc.c (scm_cellp): New function: C predicate to determine if an
5818 SCM value can be regarded as a pointer to a cell on the heap.
5820 * gc.h: Added declaration of scm_cellp.
5822 * gdb_interface.h: New file: The GDB interface header from the GDB
5825 * gdbint.c: New file: GDB interface.
5827 * gdbint.h: New file: GDB interface.
5829 * libguile.h: Added #include <libguile/gdbint.h>.
5831 * init.c (scm_boot_guile): Added scm_init_gdbint.
5833 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5834 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5835 found if object files and source are kept separate).
5837 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5839 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5841 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5843 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5844 TK_SRC_DIR; they're not relevant any more.
5846 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5847 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5849 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5851 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5852 search path, so we can find the <libguile/MUMBLE.h> headers.
5854 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5856 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5857 implicit in the .c.o rule.
5858 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5861 Put the library path in a header file, instead of passing it on
5862 the command line in every compilation.
5863 * Makefile.in (libpath.h): New target.
5864 (feature.o): Depend on libpath.h.
5865 (clean): Delete libpath.h.
5866 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5867 * feature.c: ... #include "libpath.h" here.
5868 * .cvsignore: Ignore libpath.h.
5870 Don't install the unwashed masses of Guile header files in the
5871 main #include path; put most of them in a subdirectory called
5872 'libguile'. This avoids naming conflicts between Guile header
5873 files and system header files (of which there were a few).
5874 * Makefile.in (pkgincludedir): Deleted.
5875 (innerincludedir): New variable; this and $(includedir) are enough.
5876 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5877 (installed_h_files): Divide this up. Now this variable lists
5878 those header files which should go into $(includedir) (i.e. appear
5879 directly in the #include path), and ...
5880 (inner_h_files): ... this new variable says which files appear in
5881 a subdirectory, and are referred to as <libguile/mumble.h>.
5882 (h_files): List them both.
5883 (install): Create innerincludedir, not pkgincludedir. Put
5884 the installed_h_files and inner_h_files in their proper places.
5885 (uninstall): Corresponding changes.
5886 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5887 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5888 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5889 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5890 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5891 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5892 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5893 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5894 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5895 vports.h, weaks.h: Find __scm.h in its new location.
5896 * __scm.h: Find scmconfig.h and tags.h in their new locations
5897 (they're both "inner" files).
5899 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5901 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5903 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5905 * posix.c: Doc fixes.
5907 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5909 * socket.c: Don't include a prototype for inet_aton; just use a
5910 K&R style declaration, to avoid warnings but minimize the chance
5911 of conflicts with the system.
5913 On NextStep, <utime.h> doesn't define struct utime, unless we
5914 #define _POSIX_SOURCE before #including it.
5915 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5916 * acconfig.h: New comment text for above CPP symbol.
5917 * configure.in: Call it.
5918 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5920 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5922 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5923 testing for __EMX__.
5925 * posix.c: #include <libc.h>, if it exists.
5927 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5928 don't even know if the latter exists.
5930 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5931 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5932 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5934 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5936 (scm_init_posix): Use them when initializing the Scheme constants
5939 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5941 * Makefile.in (libdir, includedir, bindir): Use the
5942 autoconf-supplied values, instead of deriving them ourselves.
5943 (pkgincludedir, datadir, pkgdatadir): New variables.
5944 (install, uninstall): Put the header files in a special
5945 subdirectory, not in the main search path.
5947 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5948 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5950 * Makefile.in (IMPLPATH): Deleted; never used.
5952 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5953 on the Tcl/Tk source any more.
5954 (INCLUDE_CFLAGS): Remove references to the above.
5956 * Makefile.in (version.o): Corrected dependencies.
5958 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5960 * libguile.h: #include "version.h"
5962 * init.c (scm_boot_guile): Call scm_init_version.
5963 * gscm.c (gscm_run_scm): Call scm_init_version.
5965 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5966 GUILE_VERSION): AC_DEFINE these.
5967 (acconfig.h): #undef the above symbols.
5969 * Makefile.in (libobjs): Add version.o.
5970 (installed_h_files): Add version.h.
5971 (c_files): Add version.c.
5972 (gen_c_files): Add version.x.
5973 (version.o): New rule.
5974 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5975 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5976 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

5978 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5979 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5980 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5981 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5982 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5983 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5984 weaks.o): Add version.h to dependency lists.
5985 (markers.o): Remove duplicate rule.
5987 * version.h: New file.
5989 * version.c: New file.
5991 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5993 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5994 array; use it appropriately. Since GCC is quite happy to
5995 subscript functions, it never warned us about this; we should use
5996 -Wpointer-arith in the future. I guess we never tested
5999 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6001 * socket.c: Doc and copyright fixes.
6003 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6005 * debug.c: Fixed and improved gdb support.
6007 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6009 * socket.c: Added declaration of inet_aton to avoid compiler
6010 warning. (Hope this solution is correct.)
6012 * stime.c: Added declaration of ftime. (This is missing in
6015 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
6017 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6019 * Makefile.in (c_files): add strerror.c.
6021 * strerror.c: new file from Emacs' sysdep.c.
6022 maybe configure should also check for sys_errlist.
6024 * configure.in (AC_REPLACE_FUNCS): add strerror.
6026 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6028 * debug.c (scm_init_debug): Added initialization for
6029 scm_evaluator_traps.
6031 * debug.h, debug.c: Various name changes.
6032 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
6033 "debug-options-interface". See commentary in options.c.
6035 * options.h, options.c: Options now have documentation strings.
6036 Also added a long explanatory commentary.
6038 * eval.c, print.h, print.c, read.h, read.c: Modifications to
6041 * gscm.c, init.c, root.c, throw.c: Bug fixes:
6042 last_debug_info_frame is now updated in all cases.
6044 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
6047 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6049 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
6050 Added option STACK_CHECKING.
6052 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6054 * Makefile.in: Added {debug,options,srcprop}.{h,c}
6056 * __scm.h: Removed symbols for debugging support.
6058 * acconfig.h: Added symbols for debugging support.
6060 * configure.in: Added user option for debugging support.
6061 --enable-debug will include the debugging code into libguile.a.
6063 * continuations.c (scm_make_cont): Enlarged the #if 0 around
6064 scm_relocate_chunk_to_heap.
6066 * debug.c: New file: low-level debugging support. It also
6067 includes support for debugging with gdb. (The extensions to gdb
6068 are written by Per Bothner at Cygnus.)
6070 * debug.h: New file: low-level debugging support.
6072 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6073 argument pairs. Extensive modifications to the debugging
6074 evaluator. Added "SECTION:" commentaries to clarify what happens
6075 when, during double compilation. Renamed EVALIMP --> EVALIM.
6076 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6077 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6078 the beginning of the file. New procedure: scm_unmemocopy.
6079 Added some global state variables needed by the debugging
6080 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6081 check_entry, check_apply, check_exit, debug_options and
6082 evaluator_traps. New acro: undefine.
6084 * eval.h: Renamed EVAL --> XEVAL.
6086 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6087 --> scm_make_weak_key_hash_table.
6089 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6090 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6092 * libguile.h: Conditionally include debug.h
6094 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6095 scm_object_properties shouldn't return handle. `handle' now gets
6096 initialized in scm_set_object_properties_x. scm_object_properties
6097 doesn't any longer create an entry in scm_object_whash.
6099 * options.c: New file: handling of run time options.
6101 * options.h: New file: handling of run time options.
6103 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6105 * print.c: New procedure: scm_print_options
6107 * print.h: Defines for print options.
6109 * read.c: New procedure: scm_read_options
6111 * read.h: Defines for reader options.
6113 * root.h: Added scm_source_whash among scm_sys_protects.
6115 * srcprop.c: New file: source properties.
6117 * srcprop.h: New file: source properties.
6119 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6120 (Bug found by A. Green.)
6122 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6124 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6126 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6128 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6130 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6131 and should be called by the final client.
6133 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6135 * gc.h: Use the PROTO macro when declaring functions.
6136 * gc.c: Use the PROTO macro when declaring static functions.
6137 Remove the CPP hair around function definitions.
6139 * gc.c (scm_init_storage): Initialize scm_asyncs.
6141 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6142 preprocessor symbol; "__scm.h" is where it might get #defined.
6143 * __scm.h: Similar: #include <scmconfig.h> before testing
6146 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6148 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6150 * init.c (scm_boot_guile): Add init_func argument; call
6151 (*init_func) instead of calling scm_appinit; it's ucky to
6152 hard-code names for the user's procedures.
6153 * init.h (scm_boot_guile): Adjust declaration.
6155 * __scm.h (PROTO): New macro, for declaring functions with
6158 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6159 eliminate all the __STDC__ conditionals.
6160 (scm_boot_guile): Add declaration.
6161 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6162 Remove __STDC__ conditionals around function definitions; the
6163 declarations in init.h will provide the same information, more
6166 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6167 complain about it in the error message; the error message is
6168 adequate without that note, and there's nothing the user can do
6171 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6173 * Makefile.in (ancillary): Drop def.sed.
6175 * posix.c (scm_init_posix): Use numeric values, rather than
6176 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6177 F_OK. The symbols aren't available on some systems, and I'm
6178 pretty sure their values are fixed by common widespread practice.
6179 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6181 More functions unavailable on some systems.
6182 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6183 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6185 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6186 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6187 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6188 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6189 stub that signals an error as the #else.
6191 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6193 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6195 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6197 * unif.c: include ramap.h.
6199 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6201 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6203 * ports.c: include sys/ioctl.h.
6205 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6207 * configure.in: check for sys/ioctl.h.
6209 * ports.c: include <malloc.h> not "malloc.h".
6211 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6213 * fports.c: remove ttyname and tmpnam declarations.
6215 * posix.c: fewer ttyname declarations.
6217 * fports.c: include <string.h> not "string.h".
6219 * init.c, ioext.c: include string.h and unistd.h.
6221 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6223 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6224 genio.c, simpos.c, vports.c: include string.h.
6226 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6228 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6230 (scm_addr_buffer_size): change type from scm_sizet to int.
6231 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6232 from scm_sizet to int.
6234 * error.c: include unistd.h.
6236 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6239 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6241 * __scm.hd, def.sed: deleted.
6243 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6245 Changes for NeXT, suggested by Robert Brown.
6246 * configure.in: Call AC_TYPE_MODE_T.
6247 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6248 NeXT. Put header file list in alphabetical order.
6249 * configure, scmconfig.h.in: Regenerated.
6250 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6252 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype

6286 (installed_h_files): Put in alphabetical order.
6287 Remove duplicate entries for markers.h and unif.h.

6289 (ancillary): Renamed from anillery; all uses changed. Remove
6290 PLUGIN; it's a directory, and needs special treatment in dist-dir.

6293 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6295 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6296 every if must have an else, or else the whole command has a
6297 non-zero exit code whenever the if's condition is false.

6364 matter so long as it is non-0 (got rid of "* 4").
6366 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6368 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6369 since its definition was bogus).
6371 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>

6375 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6377 * ports.c: removed functions relating to the mapping between ports
6378 and descriptors. (That stuff is unix-specific and should be collected
6379 in a separate library).

6386 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6387 handled correctly (SCM_FREEP was applied to them) -- test for
6388 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6556 initialization to fix a race condition.
6558 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6582 set the multi_byte flag correctly in symbols. This is wrong.
6583 intern_obbary_soft and msymbolize should take an extra parameter.

6585 The weird symbol syntax is also a bit bogus (emacs doesn't quite
