1 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
3 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
4 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
5 (scm_make_named_hook): New function.
7 * feature.c: Added #include "eval.h".
9 * modules.c (scm_make_module): Beautify the module.
11 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
13 * modules.c, modules.h: New files: C interface to modules. (This
14 is necessary in order to interface the object system to Guile
15 properly. The guts of these modules will be replaced by the new
16 module system in the future.)
18 * init.c: Added #include "modules.h"
19 (scm_boot_guile_1): Call scm_init_modules.
20 (invoke_main_func): Call scm_post_boot_init_modules.
22 * Makefile.am: Added modules.c, modules.x, modules.h.
24 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
26 * procs.c: #include "objects.h"
27 (scm_procedure_p): Return #t also on structs which are operators.
29 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
30 <operator-metaclass> and <entity-class> to <standard-class>,
31 <operator-class> and <entity> in order to conform with STKlos
34 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
35 which isn't an operator.
36 (SCM_APPLY): Ditto, but jump to badproc.
38 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
40 * eval.c (SCM_CEVAL): Allow structs implanted in code.
41 Previously, structs implanted in code were interpreted as forms
42 the operator of which was a gloc. We solve this by checking for
43 the zero in the emulated vcell in the struct vtable. Since
44 implanted structs always will look like forms with a gloc
45 operator, execution will only be slowed down by maximally one
46 extra test-and-branch per application.
48 * evalext.c (scm_definedp): Removed check for isyms; Added a
49 second optional argument: It is now possible to supply an
50 evaluation environment in which to look for the symbol.
52 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
54 * readline.c (scm_init_readline): Set
55 rl_basic_word_break_characters. (Thanks to Ian Grant.)
57 * coop.c (coop_condition_variable_wait): Removed
58 (coop_condition_variable_wait_mutex): Folded logic of
59 coop_mutex_unlock into coop_condition_variable_wait_mutex to
60 prevent condvar signal lossage. Previously, another thread could
61 start to run after unlocking the mutex but before putting the
62 current thread on the wait queue. If that thread then would
63 signal the first, the signal would be lost. (Thanks to Christian
66 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
68 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
71 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
73 * objects.c (scm_i_make_class_object): Renamed from
74 make_class_object; exported; error checking moved to
75 scm_make_class_object and scm_make_subclass_object.
76 (scm_make_class_object, scm_make_subclass_object): Use
77 scm_i_make_class_object.
78 (scm_make_subclass_object): Let the subclass have same metaclass
81 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
83 * debug.c (scm_debug_options): Bugfix: Set the value of
84 scm_stack_checking_enabled_p after setting debug options;
85 #include "stackchk.h". (Thanks to Richard Polton.)
87 1998-11-13 Radey Shouman <rshouman@metro2000.com>
89 * unif.c (scm_array_contents): removed unnecessary test for 0
92 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
94 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
95 Replaced by macro `collect' in boot-9.scm.
97 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
99 * eval.c (scm_copy_tree): Copy source properties if existent.
101 * debug.c (scm_start_stack): Copy source when evaluating. (If we
102 don't, we may end up passing memoized source to a transformer.)
104 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
106 * stack.c (get_applybody): Help function which lookups the first
107 body form of the apply closure.
108 (read_frames): Prevent the source of the first form of the apply
109 closure from being recorded. This would only be confusing.
111 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
112 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
114 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
116 * stacks.c (read_frame): Bugfix: Removed lingering `else'
118 (read_frames): Use SCM_MACROEXPP.
120 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
122 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
123 don't contain interesting information since all arguments are
124 present in the frame which applies the compiled closure anyway.);
125 Skip the transformer application frames.
127 * print.c (scm_iprin1): Print gsubrs as primitives.
129 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
131 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
133 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
134 that we can identify these in a backtrace. (This change doesn't
135 introduce any significant speed penalty.)
137 * eval.c: Added note about `serial-map' using scm_map.
139 * read.c, read.h (scm_read_options, scm_read_opts): Removed
140 readline options. They should reside in their own options array.
142 * readline.c, readline.h (scm_readline_options,
143 scm_readline_opts): Moved readline options here.
145 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
147 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
148 SCM_ROCHARS instead of SCM_CHARS.
150 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
151 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
153 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
155 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
156 This is quite important since the latter clears the
157 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
158 every single character read...
160 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
162 * print.c (scm_iprin1): Removed suspect looking (and indeed
163 malevolent) semicolon after test for user supplied closure print
164 procedure. (Thanks to Telford Tendys.)
166 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
167 (scm_memq, scm_memv, scm_member): Do argument checking *before*
168 starting to search the list. Removed call to sloppy_mem_check.
170 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
171 procedures: Same as scm_delq_x et al, but delete maximally one
174 * options.c (scm_options, scm_init_options): GC-protect option
175 values of type SCM. (Thanks to Telford Tendys.)
177 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
179 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
180 make sure that there always is a "real" scm_lookupcar.
182 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
184 * read.c, read.h (history-length, history-file): New read options.
185 (scm_read_options): Stifle history to history length.
187 * readline.c (scm_read_history, scm_write_history): New
190 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
192 * eval.h (scm_macro_eval_x): Removed declaration.
194 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
195 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
196 Renamed and made global.
198 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
199 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
201 * evalext.c, evalext.h: New files. Contain non-R5RS things
202 having to do with evaluation.
204 * evalext.c (scm_serial_map): New procedure: Version of `map'
205 which guarantees that the procedure is applied to the lists in
207 (scm_m_sequence_to_list): New syntax: Version of `begin' which
208 returns a list of the results of the body forms instead of the
209 result of the last body form.
210 (scm_definedp, scm_m_undefine): Moved from eval.c
212 * evalext.h (scm_m_sequence_to_list): Added declaration.
214 * macros.c, macros.h: New files.
215 (scm_procedure_to_syntax, scm_procedure_to_macro,
216 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
217 scm_macro_name, scm_macro_transformer): Moved from eval.c
218 (scm_make_synt): Moved from eval.c
220 * procs.c, procs.h (scm_procedure_documentation): Moved from
223 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
226 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
228 * debug.c, print.c: Added #include "macros.h".
230 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
232 This change adds the ability to use `unread-char' multiple times
233 without interspersed reads and adds the new procedure
234 `unread-string'. The change is optimized for the common case of
235 unreading a single character. This is also the reason behind the
236 choice to store characters in the port itself: in most cases no
237 extra malloc is required.
239 The amount of code in some macros in ports.h has been increased to
240 the extent that they would fit better as C functions, but, since
241 this code belongs to the port representation, such functions
242 should be placed in ports.c which would cause calls back and forth
243 between ports.c and genio.c. That is not good for performance.
244 Also, keeping them as macros allows the compiler to do some
245 optimizations which are needed to make the current interface
246 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
248 One benchmark (Guile startup time) indicates an increase of
249 loading speed of 1%. Another (reading (using `read') boot-9.scm
250 10 times) shows no change in performance.
252 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
253 made to find a beautiful solution.)
255 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
256 (SCM_TRY_CLRDY): New macro: Only clear the first unread
257 character. (SCM_CLRDY clears all.)
258 (SCM_N_READY_CHARS): New macro: Returns number of unread
259 characters in a port. Returns wrong answer if SCM_CRDYP is false.
260 (struct scm_port_table): New fields: `entry' contains port table
261 index, `cp' points to last unread char, `cbuf' is the buffer for
262 unread chars, `cbufend' points after end of the character buffer.
264 * ports.h, ports.c (scm_unread_string): New procedure.
265 (scm_grow_port_cbuf): New function.
267 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
269 (scm_generic_fgets), fports.c (local_fgets): Use a loop
270 to read unread characters. Use SCM_TRY_CLRDY instead of
273 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
275 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
277 * genio.c, genio.h (scm_ungets): New function.
279 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
282 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
284 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
285 declarations. (Thanks to Russ McManus.)
287 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
289 * numbers.c (num2long): As a software archeologist, I'm proud of
290 this finding! :) Preliminary dating suggests an almost 4 year old
291 remnant from the SCM ancestor. The sample has been removed from
292 the finding site and is now safely stored in the repository.
294 * numbers.h: Removed prototype for num2long.
296 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
298 * gh_data.c (gh_scm2doubles): Make it possible to pass result
300 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
301 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
302 * gh.h: Updated and added prototypes.
304 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
306 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
308 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
310 * guile-snarf.in: Never generate an empty file. (Thanks to
313 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
314 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
315 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
316 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
317 gh_new_procedure5_0): Specify argument types, to appease C++
318 compilers. (Thanks to Brad Bowman.)
320 Bug reports from Russ McManus:
321 * guile-snarf.in: If the CPP environment variable is set, use that
322 as the C preprocessor, instead of the preprocessor autoconf
324 * snarf.h (SCM_PROC): Cast the function pointer passed to
325 scm_make_gsubr, to satisfy C++.
327 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
328 Use the handler passed, instead of ignoring it and using
329 gh_standard_handler. (Thanks to Etienne Bernard.)
331 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
333 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

356 * script.c (scm_compile_shell_switches): Define
357 use-emacs-interface in the root module, so the repl code can see
358 it. See today's change to top-repl in ice-9/boot-9.scm.
360 * filesys.c (set_element, get_element): Make sure that `element'
361 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
362 Boekemeier and Jorgen "forcer" Schaefer.)
364 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
366 * chars.c (scm_charnames): In ASCII character name table, make
367 newlines print as #\newline by default, not #\nl.
369 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
370 alphabetical order. Oh thrills. But it helps me know how far
371 along in the compilation I am.
372 * Makefile.in: Regenerated.
374 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
376 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
377 #bytes(...) to #y(...), and syntax for short vectors from
378 #short(...) to #h(...). This may seem nutty, but, like the other
379 uniform vectors, byte vectors and short vectors want to have the
380 same print and read syntax (and, more basic, want to have read
381 syntax!). Changing the read syntax to use multiple characters
382 after the hash sign breaks with the conventions used in R5RS and
383 the conventions used for the other uniform vectors. It also
384 introduces complexity in the current reader, both on the C and
385 Scheme levels. (The Right solution is probably to change the
386 syntax and prototypes for uniform vectors entirely.)
388 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
390 Don't use local_fgets on sockets; ftell doesn't work on sockets.
391 (Thanks to Jorgen "forcer" Schaefer.)
392 * ports.h (SCM_NOFTELL): New flag.
393 * fports.c (local_fgets): If it's set, use the generic fgets.
394 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
396 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
398 * script.c (scm_compile_shell_switches): Add handling of -q switch
399 (inhibit loading of user init file).
400 (scm_shell_usage): Add usage text for -q switch.
401 (scm_compile_shell_switches): Always load user init file first if
404 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
406 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
407 and is now broken under NetBSD. I can't fathom what it's trying
408 to do, so I've replaced it with something that I do understand,
409 which seems to work, and which isn't broken on NetBSD. "Progress?
410 You Decide." (Thanks to Perry Metzger.)
412 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
413 signed/unsigned comparison.
415 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
417 Warning fixes from Greg Harvey:
418 * unif.c (scm_array_set_x): initializer for pos
419 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
420 * struct.c (scm_struct_ref, scm_struct_set_x): Added
421 initializers for field_type, since EGCS so desparately wants to
423 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
424 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
425 when GUILE_DEBUG is defined.
426 * dynwind.h (scm_wind_chain): Same.
427 * ports.h (scm_pt_size, scm_pt_member): Same.
428 * print.h (scm_current_pstate): Same.
429 * procs.h (scm_make_cclo): Same.
431 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
433 Handle short and long long uniform arrays properly. (Thanks to
435 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
436 raeql_1): Add cases for scm_tc7_svect (short vectors) and
437 scm_tc7_llvect (long long vectors).
439 Change the way libguile and boot-9.scm are timestamped, to try to
440 get rid of these spurious mismatch warnings. Now both
441 libguile/versiondat.h and ice-9/version.scm are generated directly
442 by the configuration process, rather than having version.scm
443 generated directly, and libguile/versiondat.h generated by the
444 Makefile, which is generated by configure. It seems that
445 sometimes the Makefile would change, but versiondat.h depends on
446 Makefile.in, not Makefile, so it wouldn't get rebuilt.
447 * Makefile.am (versiondat.h): Target removed; this is generated
448 directly by the configure script now.
449 (BUILT_SOURCES): Remove versiondat.h.
450 * versiondat.h.in: New file, transformed by the configure script
452 * Makefile.in: Regenerated.
454 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
455 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
456 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
457 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
458 if we want to use them in a header file some day, we can. (Thanks
461 * stime.c (scm_get_internal_real_time): Do the arithmetic using
462 SCM numbers, so we won't have rollover problems; the range of a
463 signed long in milliseconds is about 25 days. (Thanks to Karl
466 Don't redefine sleep and usleep; fix this problem now.
467 * coop.c (sleep, usleep): Remove declarations; we don't use or
468 redefine these any more.
469 (scm_thread_usleep, scm_thread_sleep): New functions which do the
470 job of usleep and sleep in a thread-friendly way. We can use
471 these in the rest of Guile. Define versions for systems both with
473 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
474 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
475 we're just using it, not redefining it, we can use a K&R style
477 (sleep): Declare this, too, if the system hasn't.
478 (scm_sleep, scm_usleep): Use scm_thread_sleep and
479 scm_uthread_sleep if they're available; otherwise, just call the
481 * scmconfig.h.in: Regenerated.
483 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
485 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
487 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
489 * threads.c: Doc fix.
491 The argument type of usleep varies from system to system,
492 as does the return type. We really shouldn't be redefining usleep
493 at all, but I don't have time to clean that up before the 1.3.
494 release. It's on the schedule for afterwards. (Thanks to Julian
496 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
498 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
499 * scmconfig.h: Regenerated.
501 * simpos.c (scm_software_type): Procedure deleted. This isn't the
502 right way to handle system variation. Autoconf's approach is the
504 * simpos.h (scm_software_type): Declaration deleted.
506 * script.c (scm_find_executable): Don't test if unix is #defined
507 here; first, NetBSD doesn't #define it, and second, it's the wrong
508 way to go about these things. (Thanks to Perry Metzger.)
509 (dld_find_executable): Delete this MSDOS support code. This isn't
510 the way we want to support this; it needs to be rethunk at a
513 * genio.c (scm_do_read_line): Don't just politely check that the
514 line was either non-empty or EOF. Abort if it's empty and not
517 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
519 * scmconfig.h.in: Regenerated.
521 * libguile.h: Don't omit the dynamic linking functions. (Thanks
524 * genio.c (scm_do_read_line): Count lines correctly when the file
525 doesn't end in a newline.
527 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
529 * genio.c (scm_do_read_line): Maintain the line count correctly.
530 (Thanks to Harvey J. Stein and Greg Harvey.)
532 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
535 * numbers.c (big2str): Protect t from garbage collection until
536 we're done. (Thanks to Gary Houston.)
538 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
540 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
542 * Makefile.in: Regenerated.
544 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
545 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
548 Do magic to mix reads and writes on stdio FILE-based ports.
549 (Thanks to Christian Lynbech.)
550 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
552 (pre_read, pre_write): New functions.
553 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
554 local_fputs): Call them.
555 (local_fflush): Mark the port as ready for reading and writing.
556 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
557 flags on new port objects. This might not be accurate --- who
558 knows what state the FILE * is in when we get it --- but it won't
559 do extraneous calls to fflush or fseek, so it's no worse than the
560 behavior before this change.
561 * ports.h: Add comment.
563 Centralize the creation of port objects based on stdio FILE * in
564 fports.c; don't just throw them together anywhere.
565 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
566 what the rest of Guile wants. Don't set the revealed count;
567 that's only appropriate for stdin, stdout, stderr.
568 (scm_standard_stream_to_port): This function does set the revealed
570 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
571 not scm_stdio_to_port.
572 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
573 * fports.c (scm_open_file): Same.
574 * posix.c (scm_pipe): Same.
575 * socket.c (scm_sock_fd_to_port): Same.
576 * ioext.c (scm_fdopen): Same.
577 (scm_freopen): Moved from here to...
578 * fports.c (scm_freopen): ... here. This is really something that
579 munges the internals of an fport, so it should go here.
580 * fports.h (scm_stdio_to_port): Adjust prototype.
581 (scm_standard_stream_to_port, scm_freopen): New protoypes.
582 * ioext.h (scm_freopen): Prototype removed.
584 * filesys.c (set_element, get_element): This can work on both pipe
585 and file ports, so use SCM_FPORTP to typecheck, instead of testing
588 * scmconfig.h.in: Regenerated.
590 Change the definition of the functions in scm_ptobfuns so that
591 they get passed the port object, not the port's stream.
592 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
593 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
594 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
595 Pass the port itself to the scm_ptobs function.
596 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
597 scm_generic_fgets): Same.
598 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
599 getc_void_port, fgets_void_port, close_void_port): Just change the
600 argument names; these functions don't really do anything.
601 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
602 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
603 port as an argument, and use SCM_STREAM to get the stdio FILE *.
604 Also, use prototyped definitions, and get rid of the extra
606 (scm_fptob, scm_pipob): We don't need casts here any more.
607 * strports.c (prinstpt): Use prototype declarations.
608 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
609 and use SCM_STREAM to get the string info. Also, use prototyped
610 definitions, and get rid of the extra declarations.
611 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
614 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
615 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
617 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
618 scm_fgets, for consistency.
619 (scm_fptop, scm_pipob): References updated.
621 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
623 Include the source location in error messages for scripts.
624 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
625 stack is still there when we catch the error.
626 * throw.c (handler_message): If we are handling an error with a
627 message, then put together the proper arguments and call
628 scm_display_error, instead of scm_display_error_message. That
629 displays source location, if it can find it.
631 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
633 * gc.c (scm_unprotect_object): Change this so that calls to
634 scm_protect_object and scm_unprotect_object nest properly.
635 (scm_protect_object): Doc fixes.
637 * strings.c (scm_string_set_x): Require the argument to be a
638 writable string, not a substring or a symbol.
639 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
640 (Thanks to John Redford and Charbel Jacquin.)
642 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
644 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
646 * eval.c (safe_setjmp): Remove this misunderstanding.
647 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
650 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
652 * libguile.h: Mark these as C declarations, for compilation by C++
655 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
656 __cplusplus clause. I seriously doubt this ever worked the way
657 the author seems to have intended.
659 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
661 Utterly needless cleanups to hopelessly messy code.
662 * ports.c: Doc fixes.
663 (scm_fflush): Moved to ...
664 * genio.c (scm_fflush): ... here, amongst all the other port
665 method invocation functions.
666 * genio.h, ports.h: The prototype moves too.
668 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
670 * backtrace.c (display_error_body): The current frame does not
671 always have a parent frame; consider a function called directly
672 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
675 * alloca.c (alloca): Undo yesterday's changes, and simply call
676 malloc directly for storage, and abort if we don't get what we
677 want. The situation is much simpler --- just call malloc. Emacs
678 has bizarre/evil requirements (signal handlers might malloc unless
679 you set this global flag, so you have to set the flag around all
680 calls to malloc) which we are certainly not going to conform to,
681 so we can do the simple and obvious thing.
683 * coop.c (coop_condition_variable_wait): Make this function
684 static. It's only useful internally --- you should never just
685 wait on a condition variable.
686 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
688 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
690 * unif.c (scm_array_set_x): Accept any kind of number as an
691 element for a uniform vector of doubles. This is more consistent
692 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
694 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
695 works; I can't conveniently test it myself. (Thanks to Dvid
696 Tillman for the bug report.)
700 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
701 from here, not from scm_compile_shell_switches (which is a pretty
702 dumb place to do it).
703 (scm_load_startup_files): New function.
704 (scm_ice_9_already_loaded): Variable moved to here from script.c.
705 * script.c (scm_compile_shell_switches): Don't load the startup
707 (scm_ice_9_already_loaded): Variable moved.
708 * init.c (scm_load_startup_files): Prototype for new function.
709 * gh_init.c (gh_enter): Doc fix.
711 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
713 Some anti-warning changes from Greg Harvey.
714 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
715 warnings when it doesn't understand our NORETURN declarations in
717 * posix.c (scm_mknod): Similar.
719 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
721 * posix.c (scm_getpwuid): If we can't find an entry, return our
722 own message, instead of using scm_syserror --- the getpwMUMBLE
723 functions don't set `errno' to anything interesting.
725 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
727 Get rid of warnings from the cooperative threading system.
728 * threads.h (scm_single_thread_p, scm_yield,
729 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
730 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
731 scm_wait_condition_variable, scm_signal_condition_variable): Add
732 prototypes for these Scheme-visible functions.
733 * coop-defs.h (coop_next_runnable_thread,
734 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
735 Prototypes for these here, even though they're from iselect.c.
736 (coop_condition_variable_wait, coop_join): Add prototypes.
737 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
738 scm_threads_free_condvar): Make these smob functions static.
739 * coop-threads.h (coop_init): Give this a real prototype.
740 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
741 (coop_next_runnable_thread): No need to provide prototype; it's in
744 * scmconfig.h.in: .detarenegeR
746 * iselect.c, threads.c: Doc fixes.
748 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
750 * Makefile.in: Regenerated with a patched automake, to get
751 dependency generation right when using EGCS.
753 * inet_aton.c (inet_aton): Add prototype, to remove compiler
754 warning. (Thanks to Robert Pluim.)
756 * inet_aton.c (inet_aton): Reassure the compiler that the
757 arguments to the <ctype.h> macros are all unsigned characters, not
760 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
762 Getting rid of more warnings...
763 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
764 today's change to ../configure.in.
765 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
766 * scmconfig.h.in: Regenertaded.de.,.__
767 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
768 (scm_localtime, scm_mktime): Use a const char * to manipulate the
771 * readline.c: Doc fix.
772 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
773 * readline.h (scm_filename_completion_function): Add prototype.
774 (scm_init_readline): Make this into a prototype.
776 * readline.c (scm_filename_completion_function): Use SCM_PROC to
777 declare this, instead of calling scm_make_subr manually.
779 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
781 * readline.h (scm_init_readline): Add prototype for this.
782 (scm_init_readline): Make this a real prototype.
784 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
786 Warning fixes from Maciej Stachowiak:
787 * backtrace.h (scm_display_application, scm_backtrace): Add
789 * debug.c (scm_m_start_stack): Make this function static.
790 * fluids.h (scm_fluid_p): Add prototype.
791 * procprop.c (scm_i_procedure_arity): Make this function static.
792 * regex-posix.c (scm_regexp_error_msg): Make this function static.
793 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
794 * root.h (scm_dynamic_root): Add external prototype.
795 * scmsigs.h (scm_usleep): Add external prototype.
796 * script.h (scm_init_script): Use prototype, not K&R decl.
797 * stacks.h (scm_stack_id): Add external prototype.
798 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
800 1998-09-30 Mark Galassi <rosalia@cygnus.com>
802 * gh.h: took out the definitions of vset and vref, since they are
803 replaced by the proper vector routines that correspond to the R4RS
806 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
808 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
809 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
810 third argument, a C expression that should result in a SCM value,
811 which is used to initialize the variable. Reimplemented
812 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
815 * version.h (scm_libguile_config_stamp): Add prototype.
816 (From Maciej Stachowiak.)
818 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
820 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
821 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
823 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
825 * print.c (scm_iprin1): Rather than having one i, and using it in
826 several places, declare a fresh i local to each block where it is
827 used, and give it a signedness appropriate to its use in each case.
830 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
833 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
834 signed/unsigned clashes.
836 * posix.h (scm_tmpnam): Added prototype.
838 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
839 scm_make_subclass_object): Add external prototypes.
841 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
842 comparison is okay here.
844 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
846 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
847 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
849 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
852 * load.c (swap_port): Make this function static.
854 * load.c (scm_search_path): Make max_path_len and max_ext_len
855 unsigned, since they're compared against string sizes.
857 * load.c (init_build_info): Make i unsigned.
859 * ioext.h (scm_read_line): Add prototype.
861 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
862 scm_hash_fn_remove_x): Make hash bucket index local variable k
863 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
864 accurately as possible.
866 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
867 comparisons, and range checking to make sure those casts are
870 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
871 signed/unsigned comparisons.
873 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
874 avoid signed/unsigned comparisons.
875 * smob.h (scm_numsmob): Change extern declaration to match.
877 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
878 avoid signed/unsigned comparisons.
879 * ports.h (scm_numptob): Change extern declaration to match.
880 (scm_current_load_port, scm_set_port_line_x,
881 scm_set_port_column_x): New prototypes.
883 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
884 test code, and it causes warnings.
886 * gh.h (gh_int2scmb, gh_uniform_vector_length,
887 gh_uniform_vector_ref): Added prototypes.
889 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
890 debugging support unconditionally. That's backtrace.c, stack.c,
891 debug.c, and srcprop.c.
892 (EXTRA_libguile_la_SOURCES): Omit those from here.
893 * Makefile.in: Regenerated.
895 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
897 * options.c (scm_options): Bugfix: Allow empty list of options!
899 * debug.c, debug.h (scm_single_step): Removed.
900 (scm_with_traps): New procedure. This procedure could easily be
901 written in Scheme but needs to be highly optimized.
903 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
905 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
906 Check SCM_TRAPS_P before trapping.
908 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
910 Changes to avoid signed/unsigned comparison warnings.
911 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
912 (scm_gc_sweep): Make n and j local to the blocks they're used in,
913 so they can have appropriate types for each application. Make i
914 signed. Use initializers in some spots. I'll probably pay for
916 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
917 (scm_must_realloc): Make nm unsigned.
918 (init_heap_seg): Make new_seg_index and n_new_objects signed.
919 (scm_init_storage): Use prototype-style definition, and make the
921 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
922 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
924 * filesys.c (scm_readlink): Make local vars rv and size ints, to
925 avoid signed/unsigned comparison warnings, and because the return
926 value of readlink may be -1. Don't bother casting the third
927 argument to readlink.
929 * filesys.c (scm_dirname, scm_basename): Move these to their own
930 page, at the end of the file.
931 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
933 * eval.h (scm_eval_options_interface): Add external prototype for this.
934 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
936 * eval.c (scm_lookupcar1): Make this static.
938 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
939 Make these prototype declarations, not K&R-style.
941 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
942 unsigned comparison warning.
944 * appinit.c: File removed. It had a single function in it, empty,
945 whose reason for existence is explained in no documentation or
946 comment. I think it's there as a default for some Tcl-style
947 initialization, but Tcl abandoned that approach a while ago.
948 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
949 (BUILT_SOURCES): Remove appinit.x.
950 * Makefile.in: Regenerated.
952 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
954 * Makefile.in: Regenerated using the last public version of
955 automake, not the hacked Cygnus version.
957 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
959 Remove Totoro kludge.
960 * Makefile.in, scmconfig.h.in: Regenerated.
961 * init.c, readline.c: Don't check if TOTORO is #defined.
963 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
965 * Makefile.am: Adjust for new thread configuration system.
966 (INCLUDES): Include the value of THREAD_CPPFLAGS.
967 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
969 (THREAD_LIBS): Definition deleted; automake will generate such
970 things automatically.
971 * Makefile.in: Regenerated.
973 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
975 Simplify smob and port marking; set the mark bit in the generic
976 marking code, and make marker routines only responsible for
977 turning up outgoing pointers.
978 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
979 before calling the marking function. Don't call the marking
980 function if it's zero.
981 * markers.c (scm_mark0): Just return #f. This function isn't
982 necessary at all now, but it's harmless to call it. We'll leave
983 it in so other folks' code doesn't croak at link time.
984 (scm_markcdr): Don't call SCM_SETGC8MARK.
985 * async.c (mark_async): Don't call SCM_SETGC8MARK.
986 * dynl.c (mark_dynl_obj): Same.
987 * root.c (mark_root): Same.
988 * srcprop.c (marksrcprops): Same.
989 * unif.c (markra): Same.
990 * variable.c (scm_markvar): Same.
991 * ports.c (scm_markstream): Same.
992 (void_port_ptob): Specify zero for our marking function.
993 * debug.c (debugobjsmob): Same.
994 * dynwind.c (guardsmob): Same.
995 * filesys.c (dir_smob): Same.
996 * fluids.c (fluid_smob): Same.
997 * fports.c (scm_fptob, scm_pipob): Same.
998 * mallocs.c (mallocsmob): Same.
999 * regex-posix.c (regex_t_smob): Same.
1000 * smob.c (freecell, flob, bigob): Same.
1001 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
1002 * throw.c (jbsmob, lazy_catch_funs): Same.
1004 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1006 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
1007 scm_copy_tree on code in order not to let memoized code to leak
1008 out. Thus, scm_copy_tree needs to copy vectors as well since
1009 quasiquote can introduce evaluated code also inside vector
1012 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1014 * eval.c (scm_copy_tree): Removed ability to copy vectors.
1016 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
1017 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
1020 * unif.c: Say that ivect and uvect are of type signed and unsigned
1021 long instead of int in commentary so that it correctly describes
1024 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1026 * stime.c: Removed declaration of strptime. (It should be
1027 declared by the system headers. If it turns out that some systems
1028 don't, we'll handle that then.) (Thanks to Greg Troxel.)
1030 * stime.h: Renamed TIMEH --> STIMEH
1032 * backtrace.c (scm_display_error, scm_display_backtrace): In order
1033 to increase portability, don't use structure assignment.
1034 (Thanks to Nicolas Neuss.)
1036 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
1038 (finalize_fd_sets): Added empty statement after last case label.
1039 (Thanks to Nicolas Neuss.)
1041 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
1044 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
1046 * init.c, readline.c: OK, I won't have these readline.x bug
1047 reports anymore. We've had them since April. The current reason
1048 is a completely unintelligible failure of totoro.red-bean.com to
1049 do the test for rl_getc_function in libreadline correctly. This
1050 kludge overrides the test if we're on totoro so that the snapshot
1051 generation process can work.
1053 * readline.c: Define a strdup replacement if not existent on system.
1055 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1057 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
1058 This change makes scm_make_vector R5RS compatible. We cannot keep
1059 the third argument since people want to be able to deduce the form
1060 of the C function call only by looking at R5RS. (At the same time
1061 we have removed some unnecessary complexity!)
1063 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
1064 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
1065 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
1066 argument in call to scm_make_vector.
1068 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1070 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
1071 This macro is useful in applications.
1073 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1075 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
1076 (scm_parse_path, scm_search_path): New Scheme level procedures.
1078 * load.h (scm_internal_parse_path, scm_parse_path,
1079 scm_search_path): Declared.
1081 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1083 * filesys.c (dirname, basename): New procedures.
1085 * init.c (scm_boot_guile_1): Removed condition around
1088 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
1089 new data type (guards) for representation of C level guards and
1090 data on the wind chain.
1091 (scm_internal_dynamic_wind): New function.
1093 * dynwind.h: Declare scm_internal_dynamic_wind.
1095 * root.h (scm_root_state): Added scm_cur_loadp.
1097 * root.c (mark_root): Added comment about cur_loadp.
1099 * load.c: #include "dynwind.h";
1100 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1103 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1105 * ports.c (current-load-port): New procedure.
1107 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1109 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1110 not a tty, return #f.
1112 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1113 to Julian Satchell and Roland Kaufmann.)
1115 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1116 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1118 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1120 * debug.h, debug.c (scm_start_stack): New function. Implements
1121 the guts of old scm_m_start_stack.
1123 * debug.c (scm_m_start_stack): Use scm_start_stack.
1125 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1126 start_stack and restart_stack. (These have static scope.)
1128 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1130 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1131 readline functions to come in release 2.3. (Thanks to Chet
1133 (handle_errors): Use the above functions.
1135 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1137 * readline.c: Improvements for readline support: Handle errors
1138 better; Implement before-read-hook.
1140 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1142 * init.c (scm_boot_guile_1), readline.c: Test for
1143 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1144 assure that we have version >= 2.1.)
1146 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1148 * readline.c (scm_readline): Defer interrupts while we're calling
1151 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1152 away the string to add_history.
1153 (completion_function): Do completion for readline. (Thanks to
1155 (scm_filename_completion_function): New procedure: Filename
1157 (current_input_getc): New function. Use this one instead of
1158 standard getc from readline.
1160 * throw.c, throw.h (scm_handle_by_throw): New function: This
1161 handler throws errors to next handler on the dynwind chain.
1163 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1165 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1168 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1170 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1172 (scm_procedure_properties): Modified to return arity together with
1174 (scm_procedure_property): Added the read-only property `arity'.
1175 (scm_set_procedure_property_x): It is an error to set the `arity'
1178 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1179 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1181 * procprop.h (scm_sym_arity): New symbol.
1183 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1184 to set the dispatch procedure of an operator or entity object.
1186 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1187 Made procedure slots read-only.
1189 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1190 scm_tcs_cons_gloc case in zero args switch; Fixed args
1191 construction for operators in scm_tcs_cons_gloc case in two args
1194 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1196 * fluids.c: Removed use of assert.h (in order to avoid
1199 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1201 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1203 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1204 change makes the evaluator safer at the cost of evaluation speed.
1205 It handles the case when the user has added a non-immediate
1206 improper end of the application form, e.g., `(+ 0 . x)'.
1207 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1208 minimize the extra cost as much as possible. The new code is
1209 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1210 problem with structs planted directly in the code (e.g. by a
1211 macro). This no longer causes segmentation fault. (Thanks to
1214 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1215 arg `proc' in order to be able to throw errors; New argument
1218 * Removed extra #include "debug.h"
1220 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1222 * scmsigs.c: Declare usleep as returning void on some systems.
1223 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1226 * coop.c (usleep): Return void on some systems.
1228 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1230 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1232 * coop.c: Changed return type of usleep to int.
1234 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1235 isn't found in the OS.
1237 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1238 isn't enabled. (Thought that I had made this change ages ago...)
1240 * iselect.c: Declare bzero if not defined by OS.
1242 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1244 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1245 condition. (Thanks to John Tobey.)
1247 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1248 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1251 * __scm.h: Start the long-term project of moving to POSIX threads.
1252 Phase 1: Classification of all critical sections.
1253 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1254 for A sections. (See comments in __scm.h for details.)
1256 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1257 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1259 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1261 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1262 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1263 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1264 dependencies on $(srcdir)/Makefile.in
1265 $(top_builddir)/config.status in order to avoid circularity.
1267 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1268 from argc if argc was 0 initially.
1270 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1271 in generation of libpath.h.
1273 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1275 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1276 libguile from 2 to 3.
1278 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1280 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1282 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1284 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1285 scm_set_port_column_x, scm_port_filename,
1286 scm_set_port_filename_x): Removed optional arguments. Added
1287 proper argument checking.
1289 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1290 stack size in machine words.
1292 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1293 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1294 to Ole Myren Röhne.)
1296 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1298 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1299 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1301 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1304 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1305 procedure apply: Copy argument lists before pushing them unto the
1306 environment so that the environment won't get mutated due to
1307 manipulation of procedure arguments. This should perhaps be
1308 regarded as a temporary solution until someone finds a more
1309 efficient one. (Thanks to Maciej Stachowiak.)
1311 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1313 * script.c (scm_compile_shell_switches): Use "guile" as default
1314 zero arg if argc is NULL.
1316 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1318 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1319 is zero. (Thanks to Dirk Herrmann.)
1321 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1323 * ports.c (scm_add_to_port_table): First line is now line 0
1324 (was 1). (Interface changed according to suggestion by Per
1327 * backtrace.c (display_header): Add 1 to line and column numbers
1328 when presenting them to the user.
1330 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1331 from debug.c --> eval.c
1333 * eval.h, eval.c (scm_eval_options_interface): New options
1335 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1336 i.e. stacks for new threads.
1338 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1340 * eval.c (unsafe_setjmp): Removed with #if 0.
1342 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1345 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1346 to avoid compiler warnings.
1348 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1350 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1352 * throw.c (handler_message): Print message on current error port
1353 instead of default error port. (Thanks to Maciej Stachowiak.)
1355 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1357 * ports.c (scm_add_to_port_table): allocate in units of
1358 struct scm_port_table *, not struct scm_port_table.
1359 * posix.c (scm_close_pipe): remove the port from the port table
1361 Thanks to Rob Engle for both fixes.
1363 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1366 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1368 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1370 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1372 * backtrace.c (display_error_body, display_backtrace_body),
1373 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1374 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1375 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1376 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1379 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1380 don't receive the jmpbuf arg anylonger.
1381 (scm_catch): Don't accept a #f tag.
1382 (scm_throw): Check that key is a symbol.
1383 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1385 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1387 * async.c (async_pending): Removed declaration.
1389 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1391 * dynwind.c (scm_wind_chain): New debug function.
1393 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1394 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1395 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1396 extra layer of functions around the body and handler of a thread.
1397 This extra layer makes sure that the handler is called in the
1398 dynamic context of the surround (= empty dynwind list), but under
1399 the *dynamic root* of the body. We can not use the dynamic root
1400 of the surround since that root belongs to another thread => stack
1401 is not handled correctly. It may seem ugly to use this extra
1402 layer, but the extra cost in terms of execution time is really
1403 negligible compared to the total amount of time required to create
1404 a thread, and it would reduce maintainability to duplicate the
1405 crucial and complicated steps performed by cwdr.
1407 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1408 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1409 get re-enabled. The important effect of this is that interrupts
1410 are blocked during thread switching so that thread data structures
1411 don't risk getting messed up by an unfortunate signal.
1412 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1413 seems to do more aggressive optimization which actually move
1414 instructions around in these macros in a fatal way. Therefore:
1415 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1416 just superstitious...)
1417 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1418 This macro should be used instead of SCM_ASYNC_TICK since the
1419 latter doesn't do context switches any more.
1421 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1422 instead of SCM_ASYNC_TICK.
1424 * coop.c, iselect.c: Since thread switches are now performed with
1425 interrupts masked, we can't use the old mechanism of delivering
1426 signals immediately when they arrive. Signals must instead be
1427 delivered when the asyncs run *after* the end of the critical
1428 section in scm_internal_select. But this also means after context
1429 switch so that the signal will be delivered to a different thread.
1430 To avoid this, I have changed the protocol of
1431 coop_wait_for_runnable_thread and friends so that they are allowed
1432 to return the original thread. So, if a signal arrives during
1433 scm_internal_select, we won't any longer be forced do a context
1434 switch, but can remain in the same thread and deliver the signal
1437 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1438 scm_asyncs_pending and made it global.
1440 * iselect.c: Small fixes.
1442 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1443 coop_condition_variable_init, coop_condition_variable_wait,
1444 coop_condition_variable_signal): Changed return type from `void'
1445 to `int'. This is to adhere closer to the pthreads interface.
1446 This, in turn, is part of an attempt to provide C versions of the
1447 mutex and condition variable primitives which can be part of a
1448 frontend to COOP or pthreads.
1450 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1451 coop_condition_variable_destroy): New functions.
1453 * coop-threads.c (scm_wait_condition_variable): Use
1454 coop_condition_variable_wait_mutex.
1456 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1457 Definitions moved to coop-defs.h.
1459 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1460 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1461 scm_cond_destroy): New C interface to mutecis and cond vars.
1463 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1465 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1467 * iselect.c: Now several threads can wait on the same file
1468 descriptor. The behaviour is compatible with OS select: All
1469 threads waiting for the fd return with the same status.
1471 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1473 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1474 Can spawn a thread from application C code.
1476 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1478 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1479 gh_doubles2scm): New functions.
1481 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1483 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1484 commented-out version of gh_eval_str()
1486 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1488 * socket.c (scm_bind): free soka after use.
1490 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1492 * stime.c (tzvar): new variable.
1493 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1494 avoid memory leaks when allocating.
1496 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1498 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1501 * gc.c, tags.h: Doc fixes.
1503 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1505 * eval.c (macro-eval!): Removed. This function was a design bug.
1506 It allowed memoized code to leak out to the scheme level. Most
1507 things that you could do with `macro-eval!' can be done with
1510 1997-12-20 Tim Pierce <twp@skepsis.com>
1512 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1513 scm_fgets now depends on ftell(3) to know how many bytes were
1516 1997-12-15 Tim Pierce <twp@skepsis.com>
1518 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1519 dealing with strings.
1521 1997-12-13 Tim Pierce <twp@skepsis.com>
1523 Make %read-line more suitable for implementing read-line efficiently.
1524 * ioext.c (scm_read_line): Strip the terminating newline from a
1525 string, and return a cons of the string and its terminator.
1527 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1528 of the string that is read is stored in this memory location.
1529 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1530 * genio.c, genio.h (scm_do_read_line): Update caller.
1531 * ports.h (scm_ptobfuns): Update typedef.
1532 * fports.c (scm_fptob, scm_pipob): Update struct.
1534 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1536 * filesys.c (set_element): Return file descriptor.
1537 (fill_select_type): Return the highest file descriptor.
1538 (scm_select): Tell select about the highest file descriptor. On
1539 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1540 Therefore the extra overhead for calculating the maximum fd seems
1541 to be more than compensated. Is this correct? In any case,
1542 scm_internal_select will be much faster with this info.
1543 (scm_select, fill_select_type, set_element): Don't accept any kind
1544 of object in the file descriptor list or vector.
1546 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1548 * iselect.c (finalize_fd_sets): Bugfix.
1550 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1552 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1553 when using scm_internal_select (since we might switch to another
1556 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1558 * simpos.c (scm_system): always define: use sysmissing if not
1559 available. Check for HAVE_SYSTEM instead of _Windows (does
1560 Windows lack system or does it have an unusable one?).
1561 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1562 Let the argument be optional: if not supplied, call system(NULL).
1564 * ports.c (scm_close_port): relax the type check from OPPORTP to
1565 PORTP; closing a closed port is allowed.
1567 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1569 * fports.c (scm_fgets): Return if the last char in a chunk is
1570 newline. When fgets returns a string whose length is `size-1', it
1571 is ambiguous whether a whole line was retrieved, so we must check
1572 explicitly whether a line terminator is present.
1574 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1576 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1577 before taking the CDR. (Thanks to Harald Meland.)
1579 * filesys.c (scm_stat): Slightly optimized.
1581 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1583 * ports.c (scm_close_port): Make sure the port is open before
1586 * guile-snarf.in: Pass args through to gcc in a way that preserves
1587 whitespace boundaries. (Thanks to Greg Badros.)
1589 1997-12-02 Tim Pierce <twp@skepsis.com>
1591 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1592 statement. (Thanks to Doug Evans for pointing this out.)
1594 1997-12-01 Tim Pierce <twp@skepsis.com>
1596 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1598 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1600 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1601 errno macro expansion of this field name. (errno is a C
1602 preprocessor macro on some systems.)
1604 1997-11-29 Tim Pierce <twp@skepsis.com>
1606 * iselect.c: Doc fix.
1608 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1610 * init.c (scm_start_stack): Removed initialization of
1611 scm_the_last_stack_var.
1613 * backtrace.h: Declare scm_the_last_stack_var.
1615 * backtrace.c: Define scm_the_last_stack_var.
1617 * root.c (mark_root): Don't mark the_last_stack_var.
1619 * root.h (scm_root_state): Removed the_last_stack_var.
1621 * throw.c: Added #include "fluids.h"
1622 (ss_handler): `the-last-stack' is now a fluid.
1624 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1625 --> the_last_stack_fluid.
1627 * backtrace.c: Added #include "fluids.h"
1628 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1629 (scm_backtrace): `the-last-stack' is now a fluid.
1631 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1632 after scm_init_fluids.
1634 1997-11-28 Tim Pierce <twp@skepsis.com>
1636 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1638 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1639 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1641 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * iselect.c (coop_next_runnable_thread,
1644 coop_wait_for_runnable_thread): Disable interrupts so that no
1645 async is executed before a potential error_revive.
1646 (scm_internal_select): Disable interrupts during the parts of the
1647 code which manipulate the sleep queue and the file descriptors.
1649 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1651 * Makefile.am: Added iselect.c and iselect.h.
1653 * coop.c (coop_qinit): Initialize fields used by
1654 scm_internal_select.
1655 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1656 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1657 replacement in iselect.c.
1658 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1659 coop_join): If GUILE_ISELECT enabled, use
1660 coop_wait_for_runnable_thread instead of
1661 coop_next_runnable_thread.
1662 (usleep, sleep): New replacements for system functions if
1663 GUILE_ISELECT is enabled.
1665 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1667 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1669 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1670 iselect.h. Implement Scheme level `select' using
1671 scm_internal_select. (See NEWS.)
1673 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1675 * init.c: Call scm_init_iselect.
1677 * iselect.h, iselect.c: New files. Implements
1678 scm_internal_select. (See NEWS.)
1680 1997-11-27 Tim Pierce <twp@skepsis.com>
1682 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1683 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1684 and scm_must_free, since ultimately the string returned will be copied
1685 by scm_makfrom0str anyway. Also, read any characters that may have
1686 been pushed onto the port with scm_ungetc.
1687 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1688 * ioext.c (scm_read_line): Free string after Guilifying it.
1689 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1691 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1693 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1695 * gh.h: Safely wrap prototypes for c++ usage.
1697 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1699 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1700 gh_repl (argc, argv).
1702 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1704 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1705 and to invoke scm_shell().
1706 (gh_launch_pad): took out the loading of boot-9.scm from here,
1707 since it is probably best to let the user control that. In fact,
1708 gh_repl() now invokes scm_shell() which does that.
1710 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1712 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1718 yesterday's underscore patch. (Thanks to Marius Vollmer for
1721 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1723 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1724 DLSYM_ADDS_USCORE is not defined.
1726 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1728 * gh_data.c (gh_uniform_vector_length):
1729 (gh_uniform_vector_ref): started implementing the uniform types in
1732 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1734 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1735 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1737 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1739 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1740 configure.in was changed).
1742 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1744 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1745 * Makefile.in: Regenerated.
1747 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1749 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1750 OPORT is an `open' port, not an output port.
1752 * filesys.c (scm_close, set_element, get_element, scm_chown,
1753 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1754 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1755 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1756 scm_close_port, scm_port_line, scm_set_port_line_x,
1757 scm_port_column, scm_set_port_column_x, scm_port_filename,
1758 scm_set_port_filename_x, scm_port_mode,
1759 scm_close_all_ports_except, scm_set_current_output_port,
1760 scm_set_current_error_port): Likewise
1761 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1762 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1764 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1765 * backtrace.c (display_backtrace_body): Likewise
1766 * fports (scm_setvbuf): Likewise
1767 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1768 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1769 scm_getpeername, scm_send, scm_sendto): Likewise
1770 * unif.c (scm_uniform_array_write): Likewise
1772 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1774 Minor problems with substring-related tag changes.
1775 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1776 exactly what we want to leave in to detect substrings.
1777 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1778 * tags.h: Fix diagrams and comments describing the S tag bit;
1779 remove vestigial remarks about the D tag bit.
1780 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1781 * strings.c: Formatting tweaks.
1783 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1784 variable first; then SCHEME_LOAD_PATH, with a warning message.
1785 (scm_parse_path): New function.
1786 * script.c: Doc fixes.
1788 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1790 Readline support, from Daniel Risacher.
1791 * readline.c, readline.h: New files.
1792 * init.c: #include "readline.h".
1793 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1794 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1795 * Makefile.in: Regenerated.
1796 * scmconfig.h.in: Regenerated, after change to ../configure.
1798 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1800 * gh.h: gh_vector_set -> gh_vector_set_x
1802 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1804 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1805 with the ! -> _x mapping when going from Scheme to C.
1807 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1809 * gh.h (gh_reverse):
1817 (gh_assoc): added these gh_ functions implemented as macros.
1819 * gh_predicates.c (gh_null_p):
1820 (gh_string_equal_p): added these two missing predicates.
1822 * gh_list.c (gh_append):
1827 (gh_set_cdr_x): added these routines as I go through and try to
1828 complete the picture R4RS functions that should be mirrored in the
1831 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1833 * tags.h (scm_tc7_substring): Changed the comment and code to
1834 conform with the changes below. Folks! We have suddenly two new
1835 free tc7 codes!!! Jummy, jummy!
1837 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1839 * Makefile.in: Rebuilt.
1840 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1842 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1843 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1858 * tags.h (SCM_TYP7SD): Removed.
1859 (SCM_TYP7D): Removed.
1860 (scm_tc7_mb_string): Removed.
1861 (scm_tc7_mb_substring): Removed.

1864 Don't include "mbstrings.h".
1865 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1866 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1868 Don't include "mbstrings.h".
1869 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1870 (SCM_SYMBOL_SLOTS): Define as 4.
1871 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1872 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1873 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1874 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

1892 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1893 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1895 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1897 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1899 * gh_test_c.c (c_vector_test): some improvements on the vector
1902 * gh.h (gh_vector): this used to exist but do the wrong thing.
1903 Now it (almost) does the right thing, though it takes a list
1904 instead of the individual arguments. I need to see how it could
1906 (gh_list_to_vector): added this function as a macro. Corresponds
1907 to Scheme's (list->vector ...).
1908 (gh_vector_to_list): added this function as a macro. Corresponds
1909 to Scheme's (vector->list ...).
1911 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1912 gh_vector_ref, so that it resembles the Scheme routines more.
1913 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1914 resembles the Scheme routines more.
1915 (gh_make_vector): this used to be (stupidly) called gh_vector().
1916 This is the right name, since it does the same thing as the Scheme
1917 (make-vector ...) procedure.
1919 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1921 * ports.h: #include "libguile/print.h"
1923 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1924 Some indentation fixes.
1926 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1927 longer a user field; New field: class_flags.
1929 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1931 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

1934 gh_int2scmb(), which is now tagged as obsolete.
1936 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1938 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1939 macros should by convention not test for NIMPness.)
1940 (SCM_COERCE_OPORT): Adjust indentation.
1942 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1943 SCM_NIMP test before SCM_PRINT_STATE_P.
1945 * struct.c, struct.h, gc.c: Renamed:
1946 scm_struct_i_layout --> scm_vtable_index_layout
1947 scm_struct_i_vcell --> scm_vtable_index_vcell
1948 scm_struct_i_vtable --> scm_vtable_index_vtable
1949 scm_struct_i_printer --> scm_vtable_index_printer
1950 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1952 * struct.c (scm_print_struct): Use new printer slot; Default
1953 printing: Also output hex code of vtable so that type identity
1954 will be indicated as well.
1955 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1956 Removed struct_printer_var; Removed struct-vtable-offset;
1957 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1958 vtable-offset-user): New constants.
1960 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1961 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.

1963 the type represented by this vtable.
1965 * print.c (scm_iprin1): Don't print arguments of macro
1966 transformers. (They are always: exp env.); Bugfix: Unmemoize
1967 transformer source with correct environment.
1969 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1971 Streamlining of call-with-dynamic-root:

1974 there is now only one catch.
1975 (cwdr_outer_body): Removed.
1976 (cwdr_handler): New function.
1977 (scm_internal_cwdr): New function to perform the function of cwdr
1978 but take args that are more useful to C code. Also, the handler
1979 is now invoked *outside* of the new dynamic root, like the docs
1980 say. We no longer have to catch absolutely all errors, the caller
1981 is responsible for using a handler that does not throw, if he
1983 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1984 * root.h (scm_internal_cwdr): New prototype.
1986 Even more but risky streamlining:
1988 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1989 allocation of the jumpbuf of a root continuation. The changes
1990 below are controlled by it. They are now deactivated.
1991 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1992 the JMPBUF of the scm_rootcont to NULL before returning.
1994 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1995 when they are non-NULL.
1996 (scm_gc_mark): Likewise, mark only when non-NULL.
1998 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1999 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
2001 * gc.c (scm_done_malloc): New function.
2002 gc.h (scm_done_malloc): New prototype.
2004 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
2005 (struct scm_print_state) [revealed]: New field.
2006 (scm_print_state_vtable): Make visible to the outside world for
2007 type checking purposes.
2008 (scm_valid_oport_value_p): New prototype.
2010 * print.c (scm_valid_oport_value_p): New function to check whether
2011 a certain value is acceptable as a port argument.
2012 (scm_print_state_vtable): New variable.
2013 (scm_free_print_state): Set `revealed' field to false.
2014 (scm_iprin1): Call user supplied closure printer with
2015 scm_printer_apply. Print in the traditional way when there isn't
2016 one or when it returns #f.
2017 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
2018 Accept a port/print-state pair in addition to just a port.
2019 (scm_prin1): Don't return the print_state to the pool when it has
2021 (scm_printer_apply): Set `revealed' field of print_state to true.
2022 (scm_init_print): Set scm_print_state_vtable.
2023 (print_state_fluid, print_state_fluid_num): Removed.
2025 * throw.h (scm_handle_by_proc_catching_all): New prototype
2026 throw.c (scm_handle_by_proc_catching_all): New function
2028 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
2030 * Makefile.in: Regenerated with automake 1.2c.
2032 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
2034 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
2035 was looping endlessly.
2037 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
2039 * strports.c (scm_eval_string): Don't close the port.
2041 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
2042 former returns a nice normal integer. (Thanks to Daniel
2045 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
2047 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
2048 makefile variable as a build parameter called LIBS. The
2049 build-guile program will use this, for the time being.
2050 * Makefile.in: Regenerated.
2052 Thanks to Shiro Kawai:
2053 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
2054 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
2057 * Makefile.in: Regenerated with automake 1.2a.
2059 * script.c (scm_compile_shell_switches): If we hit the -c or --
2060 arguments, don't set the car of (command-line) to scm_usage_name,
2061 the prettified name of the guile executable; give it the full
2062 path, the way shells usually handle $0.
2064 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2066 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
2067 Scheme-level name `array-map' and renamed `serial-array-map' to
2068 `serial-array-map!'.
2070 * backtrace.c: Introduced exception handlers which now enclose
2071 `display-error' and `display-backtrace' so that error reporting
2072 won't get into infinite loops if an error occurs during displaying
2073 of the error. This can very easily happen with user supplied
2074 print call-back routines.
2076 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2078 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
2079 the names `serial-array-map' and `array-map' should be removed.)
2081 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2083 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2084 Added #include "objects.h"
2086 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2087 Add #include "feature.h".
2089 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2090 (modinclude_HEADERS): Added objects.h.
2092 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2093 This test is needed at many places in the code and should be
2094 abstracted. (Motivated by the need of this test in libguiletk.)
2096 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2097 (scm_eval_string), load.c (scm_primitive_load,
2098 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2099 Use SCM_EOF_OBJECT_P.
2101 * eval.c (scm_init_eval): Add feature `delay'.
2103 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2105 * scmhob.h: Removed.
2107 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2109 * list.h (SCM_LISTn): New macros. Make list creation in C code
2110 prettier. The idea comes from STk.
2112 * sequences.h, sequences.c, append.h, append.c: Removed. These
2113 files implemented non-R4RS operations which would encourage
2114 non-portable programming style and less easy-to-read code.
2116 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2119 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2120 sequences.h, #include append.h.
2122 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2125 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2127 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2129 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2131 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2133 * eval.c: Added #include "objects.h"
2135 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2138 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2139 adjacent smob numbers.
2141 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2143 * procprop.h: Added declaration of scm_i_inner_name.
2145 * gsubr.c: New global symbol scm_i_inner_name.
2147 * debug.c (scm_procedure_name): Try procedure property
2148 `inner-name' if `name' fails.
2150 * print.c (scm_iprin1): Use scm_macro_name.
2152 * eval.c (scm_m_define): Give names to macros as well; Only the
2153 first top-level definition gives a procedure/macro a name.
2154 Otherwise confusing names can turn up in backtraces.
2155 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2156 `name'; Give names to macros as well.
2158 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2159 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2162 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2164 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2166 (prinmacro): Removed. The code has been moved/merged into print.c
2167 in order to decrease code redundancy. We want macros to print in
2168 a way equivalent to procedures, and it would be silly to duplicate
2169 the required code. (We don't want to maintain two places.)
2170 (macrosmob): Print field is now a NULL pointer.
2172 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2173 scm_macro_transformer): New prototypes.
2174 (scm_tc16_macro): Declared.
2176 * print.c (scm_iprin1): Added code for printing of macros. Macros
2177 are now printed in a way equivalent to procedures.
2179 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2181 * procs.h (scm_closure_p): Added declaration.
2183 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2185 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2186 Shouldn't pass "heap" as the subr name.
2188 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2190 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2191 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2192 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2193 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2194 SCM_BOOL_T. Any non-false value is true.
2196 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2198 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2199 scm_gensym): Added prototypes.
2201 * symbols.c (scm_gensym): New function. This will speed up
2202 certain types of applications (such as macro systems) which
2203 generate lots of symbols.
2205 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2207 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2209 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2211 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2212 specifier, since (2) or (2 . 3) would cause SEGV.
2213 (scm_transpose_array): more argument checking fixes.
2215 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2217 * Makefile.in: Regenerated.
2219 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2221 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2223 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2225 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2227 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2229 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2230 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2233 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2234 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2235 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2236 scm_array_p, scm_array_rank, scm_array_dimensions,
2237 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2238 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2239 scm_array_prototype): Added case scm_tc7_wvect.
2241 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2243 * errno.h: prototype for scm_strerror.
2244 * error.c (scm_strerror): new procedure.
2246 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2248 * list.c (scm_list_append_x): Allow non-pair as last argument.
2249 This is consistent with the R4RS append and is probably the
2250 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2252 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2254 * stime.h: prototype for scm_times.
2255 * stime.c (scm_times): new procedure.
2256 * ioext.c (scm_fseek): if the first argument is a file descriptor
2258 (scm_ftell): if the first argument is a file descriptor call lseek
2260 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2261 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2263 (scm_chown): if the first argument is a port or file descriptor,
2265 (scm_truncate_file): new procedure.
2266 Add DEFER/ALLOW INTS to a few other procedures.
2267 (scm_fsync): new procedure.
2268 (scm_open_fdes): new procedure.
2269 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2271 (scm_fcntl): the first argument can now be a file descriptor. The
2272 third argument is now optional.
2274 * posix.c (scm_execl, scm_execlp): make the filename argument
2275 compulsory, since omitting it causes SEGV.
2276 (scm_sync): return unspecified instead of #f.
2277 (scm_execle): new procedure.
2278 (environ_list_to_c): new procedure.
2279 (scm_environ): use environ_list_to_c. disable interrupts.
2280 (scm_convert_exec_args): take pos and subr arguments and
2281 improve error checking.
2283 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2285 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2286 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2287 argument to SCM_ASSERT. Furthermore, the name of the function
2288 should be passed as first argument when signalling
2289 SCM_WNA. (Thanks to Thomas Morgan)
2291 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2292 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2293 dispatches on the number of actual args has a default case
2294 reporting an internal error. This is a vestige from a version
2295 that mallocated a SCM vector to hold the arguments. In the
2296 current version this check is too late: if it ever happens we will
2297 have already overstepped the bounds of the array.
2299 Also, the patch [...] adds a check for too many actual arguments."
2301 mdj: Removed check for "internal programming error".
2303 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2305 * gh_io.c (gh_write): New function.
2307 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2308 throw.c (scm_internal_stack_catch): New sibling to the other catch
2309 functions. Code moved from gh_eval.c.
2310 throw.h: Added header.
2311 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2312 scm_internal_stack_catch.
2314 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2316 * ioext.h: fix up prototypes.
2317 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2318 Scheme name is now dup->fdes.
2319 (scm_dup_to_fdes): make the second argument optional and
2320 fold in the functionality of scm_primitive_dup.
2321 (scm_primitive_dup): deleted.
2323 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2325 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2326 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2327 ultrix are defined. Use setvbuf instead of setbuf.
2328 (scm_setvbuf): new procedure.
2329 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2330 (scm_setfileno): moved from ioext.c.
2331 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2332 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
2334 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2336 * fluids.c (scm_fluid_p): New function.
2337 * fluids.h (scm_fluid_p): New prototype.

2342 state as nested data while they are printed.
2343 (print_state_fluid, print_state_fluid_num): New variables.
2344 (scm_init_print): Initialize them.
2345 (scm_iprin): If print_state_fluid carries a print_state, use that
2346 instead of creating a new one.
2347 (scm_printer_apply, apply_stub, struct apply_data): New
2348 definitions to help with calling printer functions written in
2350 * print.h (scm_printer_apply): New prototype.

2363 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2364 SCM_ASSERT: arg comes before pos.
2366 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2368 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2369 to a list of length zero correctly.
2371 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2373 Supply an `fgets' method for port objects to do fast line i/o.

2387 * ioext.h: removed scm_duplicate_port prototype.
2389 * ioext.c (scm_primitive_dup2): return the new file descriptor
2390 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2392 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2393 stream has been set.
2394 (scm_duplicate_port): deleted, there's now an implementation in
2396 (scm_primitive_dup2): do nothing if newfd == oldfd.
2398 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2400 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
2403 * ioext.h: new prototypes.
2404 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2406 * fluids.c (next_fluid_num): don't do
2407 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2409 * ports.h: prototypes too.
2410 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2412 * fports.h: prototype too.
2413 * fports.c (scm_evict_ports): moved from ioext.c.
2415 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2422 and ports (scsh compatible).
2424 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2427 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2429 * fluids.c, fluid.h: New files.
2430 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2431 (modinclude_HEADERS): Added "fluids.h"

2440 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2441 unique for the new root when it has a parent.
2443 * smob.h: Include "libguile/print.h" to make scm_print_state
2446 * dynl.c (free_dynl_obj): New function to free the dynamic object
2447 data. (dynl_smob): Use it.
2448 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2449 the dynamic object data below the linking of the object to avoid
2450 memory leak when the linking code throws an error. Now the code
2451 leaks a whole dynamically linked library when must_malloc throws,
2452 but that should be much less likely.
2454 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2456 Changes to compile under gnu-win32, from Marcus Daniels:

2458 (scm_localtime): Change SCM_EOF to SCM_EOL.
2459 (scm_mktime): Likewise.
2460 * socket.c: Don't include sys/un.h unless autoconf tells
2461 us Unix domain sockets are available.

2489 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2490 scm_misc_error, not SCM_EOF.
2492 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2493 arguments for formatting the error message, not SCM_BOOL_F. I
2494 think this is left over from the (eq? '() #f) days.
2496 * read.c (recsexpr): Give this a dummy definition if
2497 DEBUG_EXTENSIONS isn't #defined.
2499 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

2504 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2506 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2509 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2511 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2512 alloca.lo will be included in @LIBLOBJS@. Something better than
2513 this should be possible.
2514 * Makefile.in: Regenerated.
2516 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2518 * simpos.h: prototype for scm_primitive_exit.
2519 * simpos.c (scm_primitive_exit): new procedure, terminates the
2520 process without unwinding the stack.
2522 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2524 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2525 argument and logior its components together, so the user doesn't
2526 have to do this explicitly. Also, if regexp/basic is supplied, then
2527 turn off REG_EXTENDED.
2528 (scm_init_regex_posix): New regexp/basic symbol.
2529 (REG_BASIC): #define this if it is not already present.
2531 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2533 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2534 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2535 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2536 (DISTCLEANFILES): New target, clean *.x.
2537 * Makefile.in: Regenerated.
2539 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2541 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2542 years in usage message.
2544 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2545 * Makefile.in: Regenerated.
2547 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2548 flag; I don't think we support it.
2549 (scm_make_regexp): Make sure the user doesn't pass the
2552 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2554 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2555 name them according to the SCSH convention: regexp/mumble.
2557 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2559 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2561 * Makefile.am (libpath.h): Include the values of all the standard
2562 Makefile directory variables. Print a message, but don't print
2564 (versiondat.h): Print a message, but don't print all the commands.
2565 * load.c: #include "alist.h".
2566 (init_build_info): New function.
2567 (scm_init_load): Call it.
2568 * Makefile.in: Regenerated.
2570 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2572 * root.c: Establish a reliable catch-all handler for the new root.
2573 After all the Scheme handler function might signal an error too,
2574 and we don't want to lose that.
2575 (cwdr_inner_body): Renamed from cwdr_body.
2576 (cwdr_outer_body): New function, to establish the user's handler,
2577 and pass control to cwdr_inner_body.
2578 (cwdr): Establish the reliable catch-all handler here, and pass
2579 control to cwdr_outer_body.
2580 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2581 the user's handler through to cwdr_outer_body.
2582 * throw.c (scm_handle_by_message): Move guts into....
2583 (handler_message): New static function.
2584 (scm_handle_by_message_noexit): New function.
2585 * throw.h (scm_handle_by_message_noexit): New prototype.
2587 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2588 across this. Only works on GCC. Otherwise, we hope for the best.
2589 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2590 the feeling that real thread systems will not need this...
2592 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2594 Try to detect when people are using one version of libguile and a
2595 different version of ice-9. People have been skewing things and
2596 sending in bug reports.
2597 * Makefile.am (versiondat.h): New file to generate.
2598 * version.c: #include "versiondat.h", to get version info.
2599 (scm_libguile_config_stamp): New function.
2600 * script.c: #include "version.h".
2601 (scm_compile_switches): Call scm_version to get version number.
2602 * scmconfig.h.in, Makefile.in: Regenerated.
2603 * Makefile.in: Regenerated.
2605 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2606 primitive definitions under their Scheme names.
2608 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2609 1:2. Helps avoid confusion between installed and uninstalled libs.
2611 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2614 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2615 backslash from definition; this should be used like: GDB_INTERFACE;
2617 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2619 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2620 new port unbuffered until its stream has been set.
2622 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2624 * ports.h: new prototype.
2625 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2627 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2629 Make things compile neatly under Sun's C compiler.
2630 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2631 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2632 unsigned, because that's what the ANSI function takes.
2633 * extchrs.h (xmbtowc): Corresponding change to prototype.
2634 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2636 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2637 argument plain char *.
2638 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2640 * tag.c (scm_tag): Remove unreachable statement.
2641 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2642 top of the word, it should be unsigned.
2644 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2645 is defined, to avoid warnings; it's only used in the
2646 conflict-checking code. Which might go away anyway.
2647 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2648 conditionals; put the label definition in an #if too, to stifle
2651 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2652 ChangeLog-threads in the distribution.
2653 * Makefile.in: Regenerated.
2655 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2657 * guile-snarf.in: Changed regexp to support CPPs that insert
2658 whitespace between lexical tokens (which munges the `%%%' snarf
2661 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2663 * load.c (scm_init_load_path): Append $(datadir)/guile to
2664 %load-path, so modules do not have to be installed in Guile's
2665 current version directory.
2667 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2669 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2670 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2671 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2672 call the sysdep functions with deferred ints.
2673 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2674 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2675 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2678 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2681 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2683 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2685 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2687 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2690 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2692 * eval.c (scm_lookupcar1): New procedure to cope with a race
2693 condition during lookup (when using threads).
2694 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2695 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2698 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2700 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2701 supplied. (Change from Tim Pierce.)
2703 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2705 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2706 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2707 default and not `()'. `#f' is the canonical non-value in Scheme,
2710 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2712 * struct.c (struct_printer): New variable that holds a handle on
2713 the Scheme variable *struct-printer*. This variable can be set by
2714 Scheme code to override the printing of structures.
2715 (scm_print_struct): If struct_printer is set, call it. If it is
2716 not set, or returns #f, print the structure in the old fashion.
2717 Include "eval.h" for scm_apply.
2719 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2721 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2722 scm_struct_i_n_words to get the number of fields, not
2723 -scm_struct_n_extra_words.
2725 On the route to fancier struct printing:
2726 * struct.c (scm_print_struct): New function to print a structure.
2727 Include "genio.h" to support it. This function doesn't do
2728 anything interesting right now, but I think it should be here
2730 * struct.h: Include "print.h" and add prototype for
2732 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2733 print structures ourself.
2735 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2737 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2738 before applying the handler in case it doesn't return.
2740 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2742 * scmsigs.h, async.h: updated.
2744 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2747 * posix.c (scm_uname): interpret only negative values as an error.
2748 Solaris normally returns a positive value.
2750 * script.c (scm_compile_shell_switches): if we are not going into
2751 an interactive repl, set scm_mask_ints to zero so that asyncs can
2754 * simpos.c (scm_system): don't ignore/unignore signals around
2757 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2760 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2761 done in boot-9.scm instead.
2763 * scmsigs.c, async.c: Major rewriting of signal handling code.
2764 (scm_sigaction): new procedure.
2765 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2767 (scm_raise): return unspecified, throw error on failure.
2769 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2771 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2772 feature, to help boot-9.scm decide whether to import the regex
2775 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2777 * eval.c: Include scmconfig.h at the beginning of the file so that
2778 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2781 * regex-posix.c: #include "_scm.h" before conditionally #including
2782 <regex.h>; the former defines HAVE_REGCOMP.
2784 * regex-posix.c: #include <regex.h> conditionally, so the file is
2785 CPP'able (for dependency scanning) even on systems that don't have
2788 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2790 Add new R4RS-compliant syntax for keywords.
2791 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2792 regardless of the setting of the `keywords' read option.
2793 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2794 can be re-read no matter what the setting of the `keywords' read
2797 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2799 Add support for POSIX regular expressions.
2801 * regex-posix.c, regex-posix.h: New files. (Some code
2802 is taken liberally from rx/rgx.c in the old Guile dist.)
2804 * init.c: Include regex-posix.h.
2805 (scm_boot_guile_1): Call scm_init_regex_posix.
2807 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2808 Add regex-posix.[ch] sources.
2809 * Makefile.in: Regenerated.
2811 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2812 to do this automatically? It didn't for me, bleh.)
2814 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2816 * fports.c (print_pipe_port): New function.
2817 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2818 latter doesn't even take the right arguments.
2820 * Makefile.am: Increment shared lib revision number. I think
2821 sometimes the uninstalled Guile finds the installed shared lib;
2822 Gord says doing this might help. As things turned out, I can't
2823 say whether it does.
2824 * Makefile.in: Regenerated.
2826 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2827 passing it as the closure argument to scm_boot_guile. (Bill
2830 * ports.c (print_void_port, putc_void_port, puts_void_port,
2831 write_void_port, flush_void_port, getc_void_port, close_void_port,
2832 noop0): Use ANSI prototypes instead of K&R declarations, so the
2833 initialization of void_port_ptob gets aggressively type-checked.
2834 Fix arguments of print_void_port and write_void_port. (Bill

2870 * script.c (scm_find_executable): Use prototype-style definition
2871 here; apparently it's not quite right to have const in a prototype
2872 and then use a K&R declaration. I wonder if stuff like this will
2873 go away if we compile with -Wrequire-prototypes, or whatever that
2874 is... (Bernard URBAN)
2876 * scmhob.h: New text from Bernard URBAN.
2878 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2880 * script.c: Don't #define const on hpux. Configure takes care of
2881 this. (Thanks to Larry Schwimmer.)
2883 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2884 decide whether to #include <unistd.h>, instead of listing a bunch
2885 of systems. Don't #include stdio twice. Removed dyked-out
2886 definition of scm_find_impl_file.
2888 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2890 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2891 library version info to 1:0.
2892 * Makefile.in: Regenerated.

2898 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2899 throw.c: Update copyright years; these files have been worked on
2900 significantly in 1997, but only had copyright years for 1996.
2901 Also, change name of copyright holder on some from Mikael
2902 Djurfeldt to Free Software Foundation; he has signed papers
2903 assigning the changes to the FSF.
2905 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2906 reason not to give the user the option.
2908 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2909 Return #f on end-of-file when scanning table (i.e. when called
2910 with no arguments). Try to catch errors, when we can.
2911 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2913 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2914 external declarations. These are useful.
2916 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * posix.c: don't include <sys/select.h> or define macros for
2919 select, since they were not used in this file.
2921 * filesys.c (scm_select): make the fifth parameter microseconds,
2922 not milliseconds. let the fourth parameter be either a real value
2923 or an integer or #f. The first, second and third arguments can
2924 now be vectors: the type of the corresponding return set will be
2926 (set_element, get_element): new static procedures.
2928 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2930 * strports.c (scm_eval_string): New function.
2931 (scm_eval_0str): Trivially re-implemented in terms of

2938 (scm_pipob): Use it in the initializer here.
2941 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2942 Use a meaningful error message when signalling an error. For
2943 this, scm_gethost must check h_errno rather than errno.
2945 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2947 * Makefile.in: Regenerated, using automake-1.1p.

2959 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2961 Ensure that shared substrings are handled properly when passed to
2962 a system call or other foreign function. Many thanks to Tim
2964 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2965 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2966 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2967 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2969 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2970 (scm_display_error_message): use RO macros when strings may be RO.
2971 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2972 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2973 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2974 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c

2984 * error.c (scm_error): Add newline to error message.
2986 * init.c (scm_init_standard_ports): Doc fix.
2988 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2990 * dynl-shl.c: Completely replaced with new code from Bernard
2993 * script.c (scm_ice_9_already_loaded): New variable.
2994 (scm_compile_shell_switches): Use it.
2996 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2998 * filesys.c (scm_input_waiting_p): add missing third argument to
3001 * stime.c (scm_localtime): copy the result of localtime before
3002 calling gmtime in case they share a buffer.
3003 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
3006 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3008 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
3010 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
3012 * Makefile.am (check-local): New target, which causes 'make check'
3013 to run gh_test_c and gh_test_repl, with some trivial input.
3014 * Makefile.in: Rgnrtd.
3016 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
3018 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
3021 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
3023 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
3024 sure how this was supposed to work.
3025 (scm_async_click): don't send SCM_TICK_SIGNAL.
3026 (scm_init_async): don't initialize %tick-thunk.
3028 * the following change doesn't affect the Scheme interface:
3029 gc-thunk is called at the end of garbage collection. however it's
3030 no longer implemented by pretending it's a signal.
3032 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
3033 system async corresponding to scm_gc_thunk.
3034 * async.h: declare scm_gc_async.
3035 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
3036 gc-thunk directly, instead of going through a signal handler.
3037 (scm_gc_async): new variable, points to the GC system-async.
3038 (scm_init_async): save the GC async as scm_gc_async instead
3039 of using system_signal_asyncs.
3040 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
3042 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
3044 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
3045 Don't screw up if we're interrupted.
3046 * Makefile.in: Regeneradet.
3048 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
3050 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
3052 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
3053 we're not using AM_INIT_GUILE_MODULE any more.
3054 * Makefile.in: Reneregated.
3056 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3058 Functions for finding variable bindings, grace à Tim Pierce.
3059 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
3060 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
3062 Get 'make dist' to work again.
3063 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
3064 * Makefile.in: Regenerated, like a surry without a fringe on top.
3066 Changes for reduced Guile distribution: one configure script,
3068 * configure.in, configure: Removed.
3069 * acconfig.h, acinclude.m4: Moved to parent directory, where the
3070 real configure script lives.
3071 * Makefile.in, scmconfig.h.in: Regenerated.
3073 * init.c: #include "script.h", to get prototype for script.c's
3076 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
3078 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
3079 scm_must_malloc, not raw malloc.
3081 * script.c (scm_compile_shell_switches): Dyke out debugging output
3084 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3086 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3088 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3089 system has them. Hope this is safe. Previously
3090 sys/timeb.h was included if HAVE_FTIME was defined or if
3091 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3092 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3094 * ioext.c (scm_setfileno): add missing third argument to
3095 scm_misc_error call.
3097 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3099 * eq.c (scm_equal_p): Correctly compare strings of different
3100 varieties. (Thanks to Tim Pierce.)
3102 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3104 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3105 #! block comment must occur on a line all by itself.
3107 Move most of the guts of shell command processing into libguile,
3108 so guile.c can be very small (and eventuallly auto-generated. (I
3109 mean, generated mechanically, not self-generated. Hmm.))
3110 * guile.c, script.c, script.h: New source files.
3111 * init.c (scm_boot_guile_1): Call scm_init_script.
3112 * libguile.h: #include "script.h".
3113 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3114 targets, for new executable.
3115 (libguile_la_SOURCES): Mention script.c.
3116 (modinclude_HEADERS): Add script.h.
3117 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3118 not dynamic linking is enabled. This is because we're generating
3119 executables now. Move CY_AC_WITH_THREADS call after those, so the
3120 values of cy_cv_threads_libs captures the libs chosen above.
3121 * Makefile.in, configure, aclocal.m4: Regenerated.
3123 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3124 We don't maintain this interface any more, and it just confuses
3127 * alloca.c: #include <scmconfig.h>, not <config.h>.
3128 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3129 it'll get included in disties.
3131 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3133 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3134 be distributed, because they confuse people.
3135 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3137 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3139 * configure.in: check for presence of gethostent (not present on
3140 OpenBSD by default).
3141 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3142 * configure, scmconfig.h.in: Regenerated.
3144 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3146 * backtrace.c (scm_backtrace): Split message string across
3147 newlines properly. GCC is more tolerant of this than other
3150 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3152 Merge threads directory into libguile.
3153 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3154 threads.h: New source files.

3156 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3158 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3159 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3160 coop-threads.c.cygnus, coop-threads.h.cygnus.
3161 * configure.in: If we're using threads, include threads.o in
3163 * _scm.h, libguile.h: threads.h lives in this directory now.
3164 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3165 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3166 currently used, but brought along for information's sake.
3167 * ChangeLog-threads: log from old 'threads' directory.
3168 * Makefile.in, configure: Rebuilt.
3170 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3172 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3175 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3177 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3179 Merge GH interface library into libguile.
3180 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3181 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3182 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3183 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3185 (EXTRA_libguile_la_SOURCES): ... here.
3186 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3187 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3188 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3189 New variables, describing how to build the gh test programs.
3190 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3191 build the test programs, and we probably should have been linking
3192 libguile.la against them all along, to support AIX shared libs.
3193 Add cflags for threads to CFLAGS; add libs for threads to new
3194 variable THREAD_LIBS, used in Makefile.am.
3195 * ChangeLog-gh: log from old `gh' subdirectory.
3196 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3198 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3200 * acconfig.h: Undo change of Apr 9; including the definition of
3201 PACKAGE in the guile headers conflicts with applications' own
3203 * scmconfig.h.in: Regenerated.
3205 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3212 when PROC is receiving no arguments.
3214 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3216 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3217 have S_IFSOCK. This is the case under Ultrix.
3219 * posix.c (scm_status_exit_val, scm_status_exit_val,
3220 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3221 Ultrix versions of WIFSTOPPED, etc., which assume that their
3222 arguments are lvalues (hmm).
3224 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3226 * eval.c: Doc fixes.
3228 * throw.c: Doc fixes; rearranged.
3230 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3232 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3234 * acconfig.h: Added entry for PACKAGE.
3235 * scmconfig.h.in: Regenerated.
3237 Changes to work with automake-1.1n, which has better libtool support.
3238 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3239 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3241 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3243 * Makefile.in: Rebuild.
3245 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3247 * stime.c (scm_mktime): take an optional zone argument.
3248 (scm_localtime): check putenv return value.
3249 (scm_strftime, scm_strptime): moved from posix.c. move #include
3251 stime.h, posix.h: update prototypes.
3252 (bdtime2c, setzone, restorezone): new static procedures.
3253 (scm_mktime, scm_strftime): use them.
3254 (scm_strftime): don't call mktime before strftime. Use
3255 filltime for return value.
3256 (filltime): convert NULL zname to #f.
3257 (scm_strptime): return a count of characters consumed, not
3258 the remaining string.
3260 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3262 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3263 (scm_mktime): likewise.
3265 Uncomment localtime and mktime.
3267 * configure.in: add AC_STRUCT_TIMEZONE.
3269 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3271 * stime.c (scm_init_stime): don't define ticks/sec.
3272 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3273 return value problem and is still portable.)
3275 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3277 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3278 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3279 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3280 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3281 cpp_err_symbols.c): Corresponding changes.
3282 * Makefile.in: Regenerated.
3284 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3286 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3287 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3288 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3289 * putenv.c: new file, from sh-utils 1.12.
3291 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3292 since allocation isn't for Scheme objects.
3293 (scm_putenv): copy strings before placing in the environment.
3295 * stime.c (scm_current_time): throw an error if time returns -1,
3296 instead of returning #f.
3297 (scm_get_internal_real_time, scm_get_internal_real_time): use
3298 scm_long2num for return value instead of SCM_MAKINUM.
3300 * stime.h: prototypes updated.
3302 * stime.c (scm_time_in_msec): apparently unused, deleted.
3304 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3306 * configure.in: check for gettimeofday.
3308 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3309 which may be more usefully portable than a gettimeofday interface.
3311 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3313 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3315 * Makefile.in: Regenerated.
3317 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3319 * stime.c (filltime): recovered static procedure.
3320 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3323 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3324 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3326 * posix.c (scm_mknod): split the mode argument into type and perms
3327 arguments, like the extra fields returned by stat.
3329 * fports.c (scm_pipob): set the close, free and print procedures.
3330 (scm_close_pipe): new procedure.
3332 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3333 define them in boot-9.scm
3335 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3337 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3338 wan't defined. Don't include fd.h.
3340 * Previously fd.h was regenerated whenever configure was run,
3341 forcing a couple of files to be recompiled.
3343 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3344 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3345 Check for _fileno as well as _file.
3347 * ioext.c: don't fd.h.
3348 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3351 * Change the stratigy for getting information about errno
3352 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3353 generating lists of symbols during the build process, which will
3354 not always work, include comprehensive lists in the distribution.
3355 To help keep the lists up to date, the "check_signals" and
3356 "check_errnos" make targets can be used.
3358 * configure.in: don't check for a command to extract errno codes.
3359 * Makefile.am: update file lists, remove errnos.list and errnos.c
3360 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3361 check_errnos targets.
3362 (CLEANFILES): remove errnos.c and errnos.list, add
3363 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3364 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3365 * errnos.default: deleted.
3366 * cpp_signal.c: new file.
3367 * cpp_errno.c: renamed from errnos_get.c.
3368 * cpp_err_symbols, cpp_sig_symbols: new files.
3369 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3370 * error.c (scm_init_error): #include cpp_err_symbols instead of
3372 * posix.c (scm_init_posix): don't intern signal symbols. #include
3375 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3377 * strop.c (scm_i_index): allow the lower bound to be equal to the
3378 length of the string, so a null string doesn't always give an error.
3380 * posix.h: new prototypes.
3381 * posix.c (scm_status_exit_val, scm_status_term_sig,
3382 scm_status_stop_sig): new functions, as in scsh. They break down
3383 process status values as returned by waitpid.
3385 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3387 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3388 configure doesn't know about it.
3390 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3392 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3394 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3395 which defines C variables with global linkage.
3397 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3399 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3402 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3404 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3405 has time to check why this doesn't work well with continuations.
3407 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3409 * Fix shell syntax error; some shells won't tolerate
3410 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3412 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3414 * posix.c (scm_uname): throw an error if uname fails instead
3417 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3419 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3422 * async.c (scm_ints_disabled): definition moved from error.c.
3424 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3426 * acconfig.h: Removed PACKAGE.
3428 * scmconfig.h.in: Regenerated.
3430 * snarf.h: g++ says it's non-portable not to specify the first
3431 argument in a varargs declaration. I introduced the first
3432 argument by using preprocessor conditionals.
3434 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3436 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3437 (scm_freopen): use RO string macros for filename and modes.
3438 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3440 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3441 (scm_mknod): use RO string macros for path.
3443 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3444 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3446 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3447 use SCM_ROSTRINGP and SCM_ROCHARS.
3449 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3451 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3454 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3455 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3456 support for byte vectors.
3458 * print.c (scm_iprin1): Limit number of vector elements printed
3459 according to pstate->length.
3461 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3463 * backtrace.c (scm_display_error_message): don't segv if message
3466 * error.h: prototype for scm_error_scm.
3468 * error.c (scm_error_scm): new procedure, reimplements scm-error
3469 in C and uses scm_error.
3471 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3473 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3474 pointer to the Scheme variable read-hash-procedures and intern it
3475 in scm_init_read. Modify scm_read_hash_extend and
3476 scm_get_hash_procedure to use the pointer.
3478 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3480 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3481 (SCM_KEYWORD_STYLE): defined.
3483 * read.c (scm_read_opts): add a keywords option. This isn't a
3484 boolean option, in case someone wants to add support for DSSSL
3486 Setup scm_keyword_prefix symbol.
3487 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3489 I've left keyword support disabled by default, since it doesn't
3490 seem to break the module system and it gives R4RS standard behaviour.
3491 It can be reactivated with (read-set! keywords 'prefix).
3493 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3495 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3496 before constructing arbiter.
3498 * eval.c (scm_m_define): Bugfix: Check that the object is a
3499 closure before setting the procedure property!
3501 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3503 * ports.c: Removed `ungetc-char-ready?'.
3505 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3507 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3508 (idea from Mikael: make it a pair so scm_permanent object only
3510 (scm_read_hash_extend): don't call scm_permanent_object.
3511 (ideas from Mikael): if chr is already in the list, replace its
3512 procedure instead of appending it again. If proc is #f, remove
3514 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3516 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3518 * gdbint.c (gdb_read): update scm_lreadr usage.
3520 * load.h: update prototypes.
3522 * load.c (scm_primitive_load, scm_read_and_eval_x,
3523 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3525 * read.h: add prototype for scm_read_hash_extend. Change args for
3528 * read.c (scm_read_hash_procedures): new variable.
3529 (scm_read_hash_extend): new procedure.
3530 (scm_get_hash_procedure): new procedure.
3531 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3532 for extended # processing.
3533 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3534 scm_read_token): remove case_i, sharp arguments. Change callers.
3536 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3538 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3539 (SCM_CASE_INSENSITIVE_P): define.
3541 * read.c: add case-insensitive option to scm_read_opts.
3542 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3543 to determine whether to convert symbol case.
3544 (default_case_i): definition removed.
3545 * read.c (scm_read_token): if case_i, downcase ic before doing
3548 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3550 * configure.in: Added configuration option `guile-debug'.
3551 Configure with --enable-guile-debug if you want a bunch of extra
3552 functions used for debugging when developing Guile.
3554 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3556 * procs.c (make-cclo): New undocumented debugging procedure: Make
3557 compiled closure with internal procedure PROC and length LENGTH.
3558 Only compiled if GUILE_DEBUG is defined.
3560 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3562 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3564 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3566 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3567 with 3 or more args internally to the evaluator.
3569 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3571 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3572 with 3 or more args internally to the evaluator. This is mainly
3573 because we don't want to pass entry and exit points of the
3574 debug support twice, but it also seems to increase the speed of
3575 the evaluator for such calls (e. g. (+ 1 2 3)).
3577 * backtrace.c (scm_display_application): New procedure:
3578 display-application; Set fancy printing parameters individually
3579 for different types of display (backtrace, error, application).
3580 (These should of course be customizable!)
3582 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3583 clear the CHECK-flags.
3585 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3587 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3589 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3591 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3592 from pairs with a GLOC in the car.
3594 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3595 otherwise `symbol-hash' will behave badly.
3596 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3597 we get segmentation fault!
3599 * symbols.c: Added #include "weaks.h". New functions:
3600 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3601 moved to an extraneous library when we split libguile.)
3603 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3605 * filesys.c (scm_stat): stat now takes fport arguments too as
3606 documented in the manual.
3608 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3610 * debug.c (scm_single_step): Bugfix: Call continuation with
3611 scm_call_continuation instead of throwing to it.
3613 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3615 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3616 argument wasn't declared to be optional.
3618 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3620 * stime.c (scm_init_stime): Add feature "current-time".
3622 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3624 * throw.h: prototype for scm_exit_status.
3625 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3626 args to derive an exit status. Allows (quit) to work from a
3628 (scm_exit_status): new function.
3631 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3633 * eval.c (scm_deval): Removed some old code.
3634 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3636 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3639 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3642 * procs.c: Introduce the existent C function scm_thunk_p at the
3643 Scheme level as well.
3645 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3648 used from C to easily lookup the value of a symbol in the current
3651 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3653 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3654 scm_init_unif in this file. This will also fix a previous problem
3657 * configure.in: Added AM_MAINTAINER_MODE
3659 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3661 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3664 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3666 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3667 source files that are not always included in libguile but should
3668 have their dependencies calculated by automake. This variable is
3669 recognized by automake, no further magic is needed.
3670 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3671 to deal exclusively with *.lo files, as it seems. The *.o files
3672 are built automatically when the corresponding *.lo file gets
3675 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3677 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3680 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3682 * unif.c (scm_array_set_x): minor change to argument error checking.
3684 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3686 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3687 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3688 They should only be included in the library at configure.in's
3690 (libguile_la_LDADD): Include the appropriate .lo files here.
3691 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3692 so we know when to build them (and their .lo bretheren).
3693 * configure.in (LIBLOBJS): New substituted variable. We let
3694 configure decide which .o files to include in LIBOBJS, and then
3695 put the corresponding list of .lo files in LIBLOBJS. The latter
3696 is what we pass to libtool.
3697 * Makefile.in, configure: regenerated.
3699 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3701 * symbols.c (scm_sysintern0): New function. Contains the core of
3702 old scm_sysintern but doesn't take a second value argument.
3703 (scm_sysintern): Now uses scm_sysintern0.
3704 (scm_sysintern_no_module_lookup): Renamed to
3705 scm_sysintern0_no_module_lookup and doesn't take a second value
3706 argument any longer.
3708 * symbols.h (scm_sysintern0: Added declaration.
3710 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3711 scm_sysintern when interning option keys. Otherwise we risk
3712 destroying the values of already interned variables.
3714 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3715 scheme-level boolean (use SCM_NFALSEP).
3717 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3719 (scm_backtrace): New function. (C version of old function from
3720 boot-9.scm) Motivation: Make it possible to display backtraces
3721 without depending on boot-9.scm. (I'm uncertain if this
3722 motivation is good enough...)
3724 * root.h (scm_root_state): Add member the_last_stack_var.
3725 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3727 * root.c (mark_root): Mark scm_the_last_stack_var.
3729 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3732 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3734 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3735 1. mark_lazy_catch didn't mark the smob.
3736 2. Both functions above have standard variants:
3737 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3738 free_lazy_catch --> scm_free0.
3740 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3742 * throw.c (scm_internal_lazy_catch): New function.
3743 (scm_lazy_catch): Rewritten to use it.
3744 (scm_ithrow): Handle the new lazy catch representation.
3745 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3746 that doesn't have a jmpbuf is a lazy catch clause.
3747 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3748 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3749 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3751 (scm_init_throw): Register the new lazy-catch smob type.
3752 * throw.h (scm_internal_lazy_catch): decl for new function.
3754 * throw.c (scm_internal_catch): Doc fixes.
3756 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3757 configure.in. Including this might cause problems if applications
3758 that link against libguile include their own copies of alloca, but
3759 if they're using autoconf, they should be adding libguile to LIBS
3760 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3761 the copy in libguile, and things will be okay. (I think.)
3763 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3765 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3767 strop.h: move prototypes too.
3769 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3771 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3774 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3775 etc. I deleted them from filesys.c long ago, but didn't
3776 notice they were here too (although ineffective since
3777 sys/stat.h wasn't included).
3779 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3781 * eval.c: Don't define alloca in GCC case. gcc will automatically
3782 use __builtin_alloca if appropriate.
3784 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3786 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3787 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3788 that values of automatic variables are preserved. See comments
3789 for safe_setjmp for details.
3791 Change from Thomas Morgan:
3792 * variable.c: Include eq.h.
3793 (var_equal): New function.
3794 (variable_smob): Use var_equal as the discriminator for variables.
3796 * throw.c (s_throw): Remove extraneous declaration.
3798 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3799 * eval.c: Add necessary CPP cruft to support that.
3800 * configure, Makefile.in, scmconfig.h.in: regenerated.
3802 Change from Thomas Morgan:
3803 * procprop.c (scm_procedure_properties): Convert the Scheme
3804 boolean returned by scm_procedure_p into a C boolean before using
3805 it as a condition for SCM_ASSERT.
3806 (scm_procedure_property): Likewise.
3808 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3809 indications of Unixness.
3812 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3814 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3816 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3818 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3819 "unknown # object" error messages.
3821 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3822 (scm_i_index) and declare it static. Add a 'direction' argument
3823 to indicate what way the search should go.
3824 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3826 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3827 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3829 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3831 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3833 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3834 to avoid clash with various scsh forks.
3836 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3838 The following two changes (ramap.c, throw.c) are motivated by the
3839 apparent unportability of forward declarations of static arrays of
3840 the form `static foo bar[];'.
3842 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3843 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3845 * throw.c (scm_throw): Moved above scm_ithrow.
3847 * options.h: Removed the extern declarations of scm_yes_sym and
3848 scm_no_sym since these are static.
3850 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3852 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3854 * Makefile.am: remove AWK=@AWK@.
3855 Add a rule for generating errnos.list.
3856 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3858 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3859 don't extract errnos, just set a variable (avoids the
3860 need to recompile error.c just because configure is run.)
3862 * unif.h: update prototypes.
3863 * unif.c (scm_uniform_array_read,write): change the offset and
3864 length arguments to start and end, for consistency.
3866 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3868 * ioext.h: update prototypes.
3869 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3870 scm_read_line_x, it's a more general procedure using an
3871 interface from scsh. read-line and read-line! are now defined
3873 Note that the new read-line trims the terminator
3874 by default, previously it was appended to the returned string. An
3875 optional argument specifies how to process the terminator (scsh
3876 compatible). For the old behaviour: (read-line port 'concat).
3877 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3878 returns a pair, but is converted to multiple values if the scsh
3881 socket.h: update prototypes.
3882 * socket.c (scm_recvfrom): for consistency with other procedures,
3883 take start and end as separate optional arguments.
3884 (scm_recv, scm_recvfrom): don't allow the second argument
3885 to be a size, only a buffer. Change the scheme names to
3886 recv! and recvfrom!. Don't return the buffer.
3888 * ioext.h, posix.h: move prototypes too.
3889 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3890 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3891 "read.h" and "unif.h".
3892 * ioext.c: include "chars.h"
3894 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3896 * dynl.c: The dynamic linking and module registration functions
3897 are now defined even when dynamic linking is not available for the
3898 host system. Some of their functionality can be done without
3899 dynamic linking; when it's really needed, they throw errors.
3901 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3903 * configure.in: Only define DYNAMIC_LINKING when one of the system
3904 dependent functions is detected.
3905 * dynl.c (scm_dynamic_func): New function to get the address of a
3906 function in a dynamic object.
3907 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3908 produced by scm_dynamic_func as the thing to call.
3910 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3912 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3913 (scm_register_module_xxx, scm_registered_modules,
3914 scm_clear_registered_modules): New functions.
3916 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3918 * symbols.c (scm_sysintern): Renamed to
3919 scm_sysintern_no_module_lookup.
3920 (scm_sysintern): New function to take the place of the old
3921 scm_sysintern. It uses the current toplevel lookup closure to give
3922 the symbol its value. This is a temporary hack to put packages
3923 like gtcltk into their own module.
3924 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3925 us whether `scm_top_level_lookup_closure_var' has been initialized
3927 * eval.c (scm_init_eval): Set it.
3929 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3931 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3932 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3934 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3936 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3937 scm_sys_dup): deleted: FD capability will be added to other
3939 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3940 scm_fd_free, fd_smob, scm_intern_fd.
3941 (scm_open): renamed from scm_sys_open. Return a port instead of
3942 an FD object. Make the mode argument optional.
3943 (scm_sys_create): deleted, it's just a special case of open.
3944 (scm_init_filesys): move interning of constants O_CREAT etc.,
3945 here (were previously using SCM_CONST_LONG macro).
3946 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3948 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3949 include "fports.h" and <stdio.h>
3950 (scm_stat, scm_select): don't support FD objects.
3952 * error.h: adjust scm_syserror_msg prototype.
3953 * error.c (scm_syserror_msg): take an extra argument for errno.
3954 Using the global value didn't always work, since it could be
3955 reset by procedure calls in the message or args arguments.
3957 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3958 I don't understand why the check was there (and what about the
3961 * strop.c (scm_string_copy): allow shared substrings to be copied.
3963 * unif.h: corresponding change to prototypes.
3964 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3965 recognize two new optional arguments: offset and length. Allow
3966 the port argument to be an integer (file descriptor, for scsh).
3967 Include <unistd.h> for "read" prototype.
3969 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3971 * socket.c: don't include filesys.h.
3973 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3975 * Makefile.am: add AWK=@AWK@ (?)
3977 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3979 Add a rule to generate errnos.c from errnos.
3980 * error.c (scm_init_error): include errnos.c.
3981 * errnos_cnvt.awk: new file, converts the list of errno codes to
3983 * errnos_get.c: new file.
3984 * errnos.default: new file, contains errnos to try if they can't
3985 be extracted from errno.h.
3986 * configure.in: if using GCC, try and extract errno codes from
3990 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3992 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3993 * Makefile.am: Made libguile into a libtool library.
3994 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3995 Set libtool_libs to indicate that libguile is a libtool library.
3996 See guile/ChangeLog for details.
3997 * .cvsignore: ignore "*.lo", the libtool library objects.
3999 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4001 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
4002 use htons in getservbyport argument.
4004 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4006 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
4007 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
4010 * objprop.c (scm_object_property): No need to take the CDR of the
4011 value returned by scm_object_properties, since Aug 20 change.
4013 * configure.in: When checking for struct linger, #include
4014 <sys/types.h> as well as <sys/socket.h>. I've never known
4015 <sys/types.h> to cause any portability problems, and Solaris's
4016 <sys/socket.h> needs it.
4017 * configure: Rebuilt.
4019 I think the Sun compiler has chosen a perverse way to interpret
4020 ANSI declarations combined with K&R definitions. We'll
4021 appease it a little bit. But when it invades France, we fight.
4022 * print.c (scm_iprlist): Change 'tlr' argument to an int.
4023 * print.h (scm_iprlist): Here too.
4024 * numbers.c (scm_divbigdig): Change definition to match
4025 declaration in numbers.h.
4026 * unif.c (scm_makflo): Change definition to match declaration in
4029 * init.c (scm_boot_guile): Don't return the value of
4030 scm_boot_guile_1. This function doesn't return a value;
4031 scm_boot_guile_1 doesn't return a value (or return at all).
4033 * eval.c (unmemocopy): Add a semicolon to appease the Sun
4036 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
4037 compile. I have a feeling this function is a bad idea anyway ---
4038 one should always test for features, not systems.
4040 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
4041 semicolons. Only pure luck kept this from being noticed earlier.
4043 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
4045 * socket.c (scm_recvfrom): Added missing semicolon.
4047 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4049 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
4050 the buffer and start and end positions for scsh networking
4053 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
4055 * configure.in: Revert previous change to this file; the problem
4056 is due to transient automake weirdness.
4057 * configure: Rebuilt.
4059 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
4060 PLUGIN/guile.libs. configure generates the latter from the former.
4061 * Makefile.in: Rebuilt.
4063 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
4064 need this if we install scripts, like guile-snarf.
4065 * configure: Rebuilt.
4067 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4069 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
4071 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
4073 * socket.c (scm_addr_vector): fix faulty scm_listify.
4075 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
4077 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
4078 style block comment is no longer considered an error.
4080 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4082 * PLUGIN/guile.libs.in: New file.
4083 * PLUGIN/guile.libs: Removed from repository.
4084 * configure.in: Create PLUGIN/guile.libs from
4085 PLUGIN/guile.libs.in. This is for including additonal libraries
4086 needed for dynamic linking.
4087 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4088 instead of PLUGIN/guile.libs.
4090 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4092 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4094 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4095 occurrences of the given element from the list, not just the
4096 first. This is how the Emacs Lisp functions behave, how the
4097 analogous Common Lisp functions behave, and (I believe) how the
4098 older Maclisp functions worked. I realize that this change may
4099 break code, but it seemed better to break it before the Guile
4102 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4103 Their prototypes were already present in gc.h, but they weren't
4105 (scm_init_storage): Initialize scm_protects.
4106 * root.c (scm_protects): New element of scm_sys_protects.
4108 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4110 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4112 * libguile.h: Added #include "libguile/net_db.h".
4114 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4115 30 change. That file is only meant for communication between the
4116 configuration process and load.c. If code linked against libguile
4117 wants to get at the paths mentioned in libpath.h, it can call
4118 functions declared in load.h.
4120 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4122 * libguile.h: Removed #include "libguile/fdsocket.h"
4124 * net_db.c: Added #include <sys/socket.h>.
4126 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4128 * filesys.c (scm_input_waiting_p): use select in preference to
4129 FIONREAD, since the latter doesn't detect EOF.
4130 Throw error if neither select nor FIONREAD available.
4132 * socket.c (scm_connect): take a port, not a fd object.
4133 (scm_fill_sockaddr): throw an error if fam is not recognised.
4134 (scm_bind): use scm_fill_sockaddr.
4135 (scm_listen): take a port, not a fd object.
4136 (scm_accept): take and return a port. return #f in the car if
4137 address can't be got
4138 (scm_sock_fd_to_port): new procedure.
4139 (scm_socket): use scm_sock_fd_to_port.
4140 (scm_addr_vector): throw error if unrecognised address type.
4141 take an extra argument with the calling procedure name.
4142 (scm_getsockname): take a port. return #f if address can't be got.
4143 (scm_getpeername): take a port. return #f if address can't be got.
4144 (scm_recvfrom): take a port. return #f for address component if can't
4146 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4147 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4149 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4151 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4152 use separate data pointers, to allow them to be designed
4153 independently and reused.
4154 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4155 Renamed from catch_body, catch_handler, and uncaught_throw; made
4157 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4159 (scm_catch): Use the above.
4160 (scm_throw): Don't bother printing a message for an uncaught
4161 throw; we establish a default handler in init.
4162 * throw.h (scm_internal_catch): Prototype updated.
4163 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4165 (struct scm_body_thunk_data): New structure, used as data
4166 argument to scm_body_thunk.
4167 * init.c (struct main_func_closure): New structure, packaging up
4168 the data to pass to the user's main function.
4169 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4170 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4171 scm_internal_catch to establish a catch-all handler, using
4172 scm_handle_by_message. This replaces the special-case code in
4174 (invoke_main_func): Body function for scm_internal_catch; invoke
4175 the user's main function, using the main_func_closure pointer to
4176 decide what to pass it.
4177 * root.c (struct cwdr_body_data): Remove handler_proc member.
4178 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4179 (cwdr_handler): Removed.
4181 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4183 * socket.h (SCM_P): update bind prototype.
4184 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4185 include "feature.h".
4186 (scm_socket): return a port, not a file descriptor object.
4187 include "fports.h" and <unistd.h>
4188 (scm_bind): take a port, not a file descriptor object.
4189 take an extra argument for address args.
4191 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4192 INADDR_NONE, INADDR_LOOPBACK.
4194 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4196 * init.c: include net_db.h and not fdsocket.h.
4197 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4199 * Makefile.am: corresponding changes.
4200 * socket.h: renamed from fdsocket.h, fix names.
4201 * net_db.h: renamed from socket.h, fix names.
4202 * socket.c: renamed from fdsocket.c.
4203 remove _sys from procedure names.
4204 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4205 add "socket" to features list.
4206 * net_db.c: renamed from socket.c.
4207 remove _sys from procedure names.
4208 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4209 add "net-db" to features list.
4210 include "net_db.h". don't include <sys/socket.h> or
4213 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4215 * tags.h (scm_tags): Removed comma at end of last enumerator.
4217 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4219 Don't use GCC extensions to allocate space for debugging frames.
4220 (Here he goes again! Why do we put up with this?!)
4221 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4222 an scm_debug_info structure, not an in-line array of them. Add
4223 'info' member, to say how many vect elements we've used, for eval
4225 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4226 a new variable debug_info_end to mark the end of vect, instead of
4227 the address of the 'info' pointer itself.
4228 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4229 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4230 (SCM_APPLY): Explicitly allocate space for debug.vect.
4231 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4232 * stacks.c: Adjusted for new debug frame structure.
4233 (RELOC_INFO, RELOC_FRAME): New macros.
4234 (stack_depth, read_frames): Use them, and new scm_debug_frame
4235 element 'info', instead of magically knowing that eval frames have
4236 an info pointer sitting after vect.
4237 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4239 (scm_init_stacks): Formatting tweaks.
4241 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4243 Give GCC more control flow information, so it can be sure that
4244 variables aren't used uninitialized.
4245 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4246 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4247 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4248 scm_misc_error): Tell GCC that these functions never return.
4249 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4250 out the field type, call abort if SCM_ASSERT returns, to placate
4252 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4253 scm_wta ever returns. We can't handle this case anyway, and this
4254 gives the optimizer more information.
4255 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4256 scm_wta ever returns.
4258 In some cases, the code is fine, but GCC isn't smart enough to
4259 figure that out; this usually happens when one variable is only
4260 initialized and used when a particular condition holds true, and
4261 we know that condition will never change within a given invocation
4262 of the function. In this case, we simply initialize the variables
4263 to placate the compiler, hopefully to a value which will cause a
4264 crash if it is ever actually used.
4265 * print.c (scm_iprin1): Initialize mw_pos.
4266 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4267 * throw.c (scm_ithrow): Initialize dynpair.
4268 * unif.c (scm_uniform_vector_ref): Initialize cra.
4269 * struct.c (init_struct): Initialize prot.
4270 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4272 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4273 if EXPR contains no expressions.
4275 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4277 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4278 cause an infinite loop (???). So much for the algebraic
4279 equivalency of variable-sized arrays and alloca...
4281 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4283 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4284 a SCM boolean, not a C boolean.
4286 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4288 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4289 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4290 rules for raising scm_mtrigger. Previously, unfortunate but not
4291 unlikely circumstances could result in almost constant invokation
4292 of the gc. Now, this situations should be less likely, but they
4293 are not prevented completely.
4295 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4297 * numbers.c (scm_fuck): Procedure removed; looks like old test
4299 * numbers.h: Prototype removed.
4301 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4303 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4304 array to a pointer, to match my Nov 21 change in eval.c.
4306 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4308 * libguile.h: Added #include "libguile/backtrace.h", #include
4309 "libguile/stacks.h".
4311 * strings.c (scm_string scm_make_string scm_string_ref
4312 scm_string_set_x scm_string_equal_p scm_string_append):
4313 Bugfix according to scm patch from Aubrey Jaffer:
4314 Corrected long-standing
4315 (not (eqv? (integer->char 128)
4316 (string-ref (make-string 1 (integer->char 128)) 0)))
4317 bug found by John Kozak <jk@noontide.demon.co.uk>.
4319 * strports.c, strports.h: Make scm_eval_0str return the value of
4320 the last expression evaluated (previously, it returned void).
4322 * strports.c, strports.h: New function: scm_read_0str. Does what
4325 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4327 * simpos.c (scm_getenv): return #f if string can't be found in the
4328 environment instead of throwing an exception, for compatibility
4329 with numerous other systems.
4331 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4333 * Makefile.am (.c.x): Use guile-snarf.
4334 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4336 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4338 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4340 * backtrace.c (scm_display_error_message): Made non-static, and
4341 renamed from display_error_message.
4342 * backtrace.h (scm_display_error_message): Added extern decl.
4343 * throw.c (uncaught_throw): Use it to display the error message.
4345 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4347 * inet_aton.c: Use #if 0, not #ifdef 0.
4349 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4351 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4352 to convert the returned value.
4353 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4354 the offset argument.
4356 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4358 Add new interface to catch/throw, usable from C as well as
4360 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4361 (scm_internal_catch): New function, replaces...
4362 (scm_catch_apply): Deleted.
4363 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4364 mechanism which is a bit more code, but can be used nicely from C
4365 and implement the Scheme semantics as well.
4366 (scm_internal_catch): This is the replacement; it's named after
4367 the analogous function in Emacs.
4368 (scm_catch): Reimplemented in terms of the above.
4369 (struct catch_body_data, catch_body, catch_handler): New
4370 functions, used by scm_catch.
4371 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4372 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4373 support for new cwdr.
4375 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4378 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4380 * acconfig.h: Added DYNAMIC_LINKING symbol.
4381 * configure.in: Add option and checks for dynamic linking.
4382 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4383 dynl.h: New files for dynamic linking support.
4384 * Makefile.am (libguile_a_SOURCES):
4386 (modinclude_HEADERS): Added "dynl.h".
4387 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4389 * init.c (scm_boot_guile_1): Call
4390 scm_init_dynamic_linking to initialize dynamic linking support.
4392 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4394 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4395 (as we Schemers say). It needs to be global, so that I can tweak
4396 it for the proper operation of unexec.
4397 (scm_boot_guile_1_live): New variable, see above.
4399 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4401 * guile-snarf.sh: Removed.
4402 * PLUGIN/guile.libs: Added dependency for -lm.
4403 * acinclude.m4: Renamed from aclocal.m4.
4404 * PLUGIN/greet: Removed.
4405 * Makefile.am, aclocal.m4: New files.
4406 * configure.in: Updated for Automake.
4408 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4410 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4411 and not top_level_lookup_thunk_var.
4413 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4415 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4417 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4419 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4420 Scheme function, instead of syntax. Single argument is now a
4423 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4425 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4426 scm_ra_divide): Properly terminate statements passed as arguments
4427 to IVDEP macros. (Thanks to Bernard Urban.)
4429 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4430 with non-constant sizes. (Thanks to Bernard Urban.)
4432 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4434 It's an "eval closure", not an "eval thunk." A thunk is a
4435 function of no arguments.
4436 * root.h (struct scm_root_state): Renamed
4437 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4438 (scm_top_level_lookup_closure_var): Renamed from
4439 scm_top_level_lookup_thunk_var.
4440 * root.c (mark_root): Uses changed.
4441 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4442 * init.c (scm_start_stack): Uses changed.
4443 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4444 Change scheme-visible name to *top-level-lookup-closure* from
4445 *top-level-lookup-thunk*.
4447 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4449 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4450 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4452 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4454 * gc.c (struct scm_heap_seg_data): Doc fixes.
4456 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4457 sweeping. Then, prepend each segment's free cells to its
4458 freelist, rather than wiping out the old value. (Thanks to Marius
4461 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4462 scm_check_freelist, scm_debug_newcell): New functions and
4463 variables, for debugging freelist problems.
4464 * pairs.h (SCM_NEWCELL): New debugging version added.
4465 * gc.h (scm_debug_newcell): Added extern declaration, used by
4466 debugging version of SCM_NEWCELL.
4468 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4470 On some systems <libc.h> conflicts with <unistd.h>, and should not
4471 be #included at all.
4472 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4473 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4474 * configure.in: Call it.
4475 * posix.c, filesys.c: Use its results to decide whether or not to
4477 * configure, scmconfig.h.in: Rebuilt with autoconf and
4480 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4482 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4483 pointer to the stdio stream before calling scm_setbuf0, so the
4484 latter will be able to retrieve it. I'm surprised this didn't
4485 segfault earlier. (Thanks to Christopher Lee.)
4487 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4489 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4492 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4494 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4495 number of stack narrowing specifier pairs. The first specifier in
4496 a pair controls inner border, the second the outer border. A
4497 number means cut that number of frames, a procedure object means
4498 cut until that object is found in operator position in a frame.
4500 * root.c (cwdr): Bugfix.
4502 * read.c: Recording of positions disabled by default.
4504 * procs.c (scm_closure_p): New function.
4506 * posix.c (scm_tmpnam): New function.
4508 * load.c: Added #include "throw.h".
4509 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4512 * load.c, load.h (scm_read_and_eval_x): New function.
4514 * eval.c: Renamed debug option "deval" to "debug".
4516 (scm_eval_x): `eval!' is no longer accessible from the scheme
4517 level. Motivation: We can't allow operations which introduce
4518 glocs into the scheme level. Guile's type system can't handle
4519 these as data. Use `eval' or `read-and-eval!' as replacement.
4521 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4522 SCM_CONSP since this is a macro!; Set vframe.prev to
4523 scm_last_debug_frame instead of 0. In this way we can look
4524 "above" the virtual start stack frame if we wish.
4525 (scm_debug_hang): New function: Useful for debugging Guile in
4526 certain tricky situations. Will probably be removed later...
4528 * debug.h: Changed semantics of debug option "backtrace". This
4529 option now only indicates whether we want automatic backtrace at
4532 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4534 * ports.c: #include "filesys.h"
4535 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4537 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4538 Motivation: This is system specific code which is related to file
4539 I/O. It also may use select. Added code by Gary Houston to
4540 detect presence of character in stdio buffers.
4542 * libguile.h: #include "libguile/libpath.h"
4544 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4545 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4546 SCM_SITE_DIR; Install libpath.h among the other include files.
4548 * load.c, load.h (scm_sys_package_data_dir): New function.
4550 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4552 * stacks.h: Bugfix: Don't use tail-array length field as stack
4553 length field! This screwed GC.
4555 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4557 * _scm.h: Added #ifndef around definition of macros min and max.
4559 * __scm.h: Added hooks for threads to plugin to in ints protection
4560 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4561 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4562 the main code in these macros duplicated and spread over multiple
4563 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4564 SCM_THREAD_SWITCHING_CODE.
4566 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4568 * snarf.h: New file.
4569 * guile-snarf.sh: New file.
4570 * Makefile.in (inner_h_files): Added snarf.h
4571 (ancillary, install, uninstall, distclean): Added actions for
4573 (.c.x): Use guile-snarf.
4574 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4575 (gen_c_files): Note that these depend on guile-snarf.
4576 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4577 now in "snarf.h". Added #include "snarf.h" to get them.
4578 * libguile.h: Added #include "snarf.h".
4579 (Patches applied and tweaked by Jim Blandy.)
4581 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4583 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4584 standards suggest against providing prototypes for system
4585 functions. Thanks to Greg Troxel.
4587 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4589 * strports.c (scm_eval_0str): New function.
4590 #include "read.h", to get prototype for scm_read.
4591 * Makefile.in (strports.o): Update dependencies.
4592 * strports.h: New prototype.
4594 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4595 scheme name from "int?" to "integer?". It seems to do the job.
4596 * numbers.h: Rename prototype too.
4597 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4600 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4601 scm_num_eq_p): Rename these according to R4RS conventions: call
4602 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4603 to making libguile R4RS compliant without ice-9...
4605 * load.c (scm_sys_search_load_path): Search for files under all
4606 extensions listed in the %load-extensions variable. If FILENAME
4607 is absolute, return it unchanged, without searching the load path.
4608 (scm_loc_load_extensions): New variable, pointing to
4609 %load-extensions' value cell.
4610 (scm_init_load): Initialize it, and the value it points to.
4611 (scm_primitive_load_path): Improve error reporting.
4613 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4614 of new Scheme variable %load-hook.
4615 (scm_primitive_load): Apply %load-hook to filename.
4617 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4619 * configure.in: add tests for figuring out whether buffered data
4620 is available in a FILE structure, which is needed by char-ready.
4622 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4625 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4626 exceptions using misc_error instead of syserror. It seems a bit
4627 odd to throw an exception if a string can't be found in the
4628 environment, but it's consistent with open-file, stat etc.
4629 (simpos.h): remove sys_ from getenv.
4631 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4632 occurs, throw an error instead of returning errno. Return value
4634 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4636 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4638 * filesys.c (scm_stat2scm): derive file type and permissions from
4639 the stat mode and append them to the returned vector.
4640 There isn't much overhead in doing this and it avoids the need to
4641 work with S_IRUSR et al. in Scheme.
4642 Define symbols scm_sym_regular etc.
4643 (scm_init_filesys): don't intern S_IRUSR etc.
4645 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4646 and s_primitive_load_path.
4648 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4650 * error.h: don't declare error symbols. prototype for scm_misc_error.
4652 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4655 * error.c: use SCM_SYMBOL to set up error keys.
4656 scm_misc_error: new procedure.
4658 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4660 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4661 between `#!' and `!#' is ignored.
4662 (skip_scsh_block_comment): New function.
4664 * feature.c (scm_set_program_arguments): New argument, FIRST.
4665 * feature.h: Update prototype.
4666 * init.c (scm_boot_guile_1): Pass new argument to
4667 scm_set_program_arguments.
4669 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4671 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4672 (scm_boot_guile): Call scm_set_program_arguments here, later than
4673 the old initialization.
4675 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4676 initialization procedure.
4677 - Delete in, out, err arguments; there are other perfectly good
4678 ways to override these when desired.
4679 - Delete result argument; this function shouldn't ever return.
4680 - Rename init_func argument to main_func, for less confusion.
4681 - Delete boot_cmd argument; main_func is more general.
4682 -Add 'closure' argument, to help people pass data to main_func
4683 without resorting to global variables.
4684 - Abort if reentered; don't bother returning an error code.
4685 - Call scm_init_standard_ports to set up the default/current
4686 standard ports; no need to pass them to scm_start_stack.
4687 - Remove code to evaluate the boot_cmd, and start the repl; let
4688 the user do something like that in main_func if they want.
4689 - Remove code to package up a return value; main_func can do any
4691 - Call exit (0), instead of returning.
4692 (scm_start_stack): Don't initialize the I/O ports here; that's
4693 weird. Delete in, out, err arguments. Move guts to
4694 scm_init_standard_ports, scm_stdio_to_port.
4695 (scm_init_standard_ports): New function, to set up current and
4696 default standard ports.
4697 (scm_start_stack, scm_restart_stack): Make these static.
4698 * init.h (scm_boot_guile): Adjust declaration.
4699 (scm_start_stack, scm_restart_stack): Remove externally
4700 visible declarations for these.
4701 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4703 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4704 written out several times in scm_start_stack.
4705 * fports.h: New declaration for the above.
4707 * feature.c (scm_set_program_arguments): New function.
4708 * feature.h: New declaration for the above.
4710 * ports.c: Formatting tweak.
4712 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4714 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4715 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4716 for obtaining the address of a car or cdr field. Motivation:
4717 &SCM_CXR make assumptions about the internal structure of the
4720 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4721 Motivation: see SCM_CXRLOC.
4723 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4724 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4725 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4726 Motivation: Safer use. Some other macros are defined in terms of
4727 these operations. If these are defined using the SCM_SETCXR
4728 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4729 to inefficiency and an <e1> with side-effects could potentially
4730 break. Also, these particular operations are heavily utilized in
4731 the garbage collector. In unoptimized code there will be a
4734 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4735 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4736 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4737 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4738 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4739 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4740 vports.c: Cleaned up use of pairs: Don't make any special
4741 assumptions about the internal structure of selectors and
4742 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4743 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4744 (Among other things, this change makes it easier to build Guile
4745 with certain compilers which have problems with casted lvalues.)
4747 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4749 * stacks.c: Improve selection of relevant stack frames when making
4750 a stack object. Introduce one level of indirection in the stack
4751 object to make it possible to "narrow" to a certain region of the
4752 stack. This facilitates making use of more clever algorithms (not
4753 implemented) for selecting relevant frames and gives a cleaner
4754 design since selection of frames can be done independently of
4755 extraction of frames from the real stack.
4756 (scm_stack_id): Also take #t as argument which means look at
4759 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4760 Turn n_tail into an integer directly representing current number
4761 of frames in stack. Add field tail.
4763 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4765 * debug.c (scm_make_memoized): Made it available at scheme level.
4766 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4767 SCM_NIMP before applying heavier predicates in argument checking.
4768 (scm_local_eval): Also take memoized object as argument.
4770 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4771 aren't created with zero length, but should such a strange
4772 creature suddenly turn up...
4774 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4776 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4777 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4779 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4781 * variable.c (scm_make_variable): Make the name hint optional, as
4783 (anonymous_variable_sym): Renamed from variable_sym. All uses
4786 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4787 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4788 of scm_primitive_load_path was also changed to
4789 "primitive-load-path", from "%try-load-path". Callers changed.
4790 We'd like to respect the convention that a function named
4791 "try-mumble" should behave just like the function called "mumble",
4792 but return #f instead of signalling some error.
4793 * load.h: Rename prototypes.
4795 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4797 * print.c (make_print_state, grow_print_state), print.h: Modified
4798 the print state representation: Don't use a tail array for
4799 recording of circular references. Resizing of the print state
4800 structure invalidates the print state pointer. To avoid passing
4801 around an indirect print state reference to all printing
4802 functions, we instead let the print state reference a resizable
4805 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4807 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4808 Don't crash when passed an improper list terminated by a
4809 non-immediate value.
4811 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4813 Allocate data for structures on an eight-byte boundary, as
4814 required by the tagging system.
4815 * struct.c (alloc_struct): New function.
4816 (scm_make_struct, scm_make_vtable_vtable): Call it.
4817 * struct.h (scm_struct_n_extra_words): Bump to 3.
4818 (scm_struct_i_ptr): New "field".
4819 * gc.c (scm_gc_sweep): When we need to free the data, use the
4820 information stored by alloc_struct to find the beginning of the
4821 block allocated to the structure, so we can free it.
4823 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4825 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4828 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4829 (scm_debug_info): New member: id.
4831 * stacks.c: Stacks are now represented as structs; Stacks have an
4832 id given to them by `start-stack'.
4833 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4835 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4836 Changed stack representation.
4838 * debug.c (scm_procedure_name): Try procedure property `name' for
4839 compiled closures aswell.
4841 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4843 * eval.c: scm_i_name moved to gsubr.c

4845 objects. (Earlier, only closures were recorded.)
4847 * procprop.h: Added declaration of scm_i_name.
4849 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4850 (scm_make_gsubr): Record names of compiled closures.
4852 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4854 * debug.c, debug.h: Removed obsolete code.
4856 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4857 stacks.c: Renamed regs --> scm_contregs.
4859 * print.c (scm_free_print_state): Cleanup print state before
4860 returning it to pool. It is better to do it here than in
4861 scm_prin1 since scm_prin1 is called often.
4863 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4864 s_set_source_property_x): Check that first argument is a pair or a
4867 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4868 scm_i_line, scm_i_column and scm_i_breakpoint global.
4870 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4871 (scm_boot_guile_1): Added calls to scm_init_backtrace and

4881 backtrace.h, stacks.c and stacks.h.
4883 * symbols.c (scm_sym2ovcell): Fixed documentation.
4885 * _scm.h (min, max): Added.
4887 * async.c: Moved `min' macro to _scm.h.
4889 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4890 SCM_BACKTRACE_INDENT.
4892 * eval.c: Added new debug options `maxdepth' and `indent'.
4894 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4896 * print.h: Added selector SCM_PRINT_STATE.
4898 * print.c: New functions: scm_make_print_state,
4899 scm_free_print_state.
4901 * print.h: Added declarations for scm_make_print_state,
4902 scm_free_print_state.
4904 * debug.c (scm_m_start_stack): New acro.
4906 * debug.h: Small cleanup.
4908 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4931 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4932 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4933 declare functions with prototypes. (Patch thanks to Marius
4936 More prototype-related changes from Marius Vollmer:
4937 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4938 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4939 * ports.h (ptobfuns): Added prototypes. This means some casting in
4941 * fports.c: Added casts for initializations, since the functions
4942 are defined to take FILE * as their stream argument, not SCM.
4943 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4944 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4945 to `char *str_data' to conform to prototype.
4947 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4949 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4951 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4953 * stime.c, stime.h: use SCM_P method.
4955 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4957 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4958 be given at least two arguments. Insist that lst's last element
4959 be a list, but don't make any requirements of its predecessors.
4961 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4963 * eval.c (scm_nconc2last): Revert last change; there seems to be
4964 other stuff going on here.
4966 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4968 * eval.c (scm_nconc2last): Make sure that each element of lst
4969 (which is a list of argument lists, except for the tail) is a
4970 proper list, i.e., finite and terminated by '().
4972 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4974 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4977 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4978 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4981 * vectors.c (scm_make_vector): Fill vectors with the undefined
4982 value, to help make Guile Scheme code more portable to other
4985 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4986 * symbols.h, tags.h: Doc fixes.
4988 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4990 * async.c (scm_take_signal): Doc fixes.
4992 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4994 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4995 want to subtract it from the modulus; we just want to leave it
4998 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
5000 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
5003 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
5005 * throw.c (scm_catch_apply): Finished implementation of
5008 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5010 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
5012 (scm_init_filesys): set "i/o-extensions" feature.
5015 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
5017 * Makefile.in (root.o): Correct dependencies.
5019 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
5021 * Makefile.in: Added dependency entry for root.o.
5023 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
5024 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
5026 * init.c (scm_start_stack): Set initial root continuation number
5029 * procs.c: New function: scm_thunk_p.
5031 * procs.h: Added declarations of scm_thunk_p.
5033 * root.c: Renamed `call-with-new-root' -->
5034 `call-with-dynamic-root'.
5035 (cwdr): Removed allocation of new root state. This should be done
5036 separately by use of scm_make_root.
5037 (scm_apply_with_dynamic_root): New function: Does what it
5038 sounds like. Needed when spawning threads.
5040 * root.h: Added member last_debug_frame to root state.
5041 Added #include "libguile/debug.h"
5043 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
5044 arguments. The motivation is that code in root.c needs catch
5045 functionality, and we want to avoid code duplication.
5046 New functions: scm_catch, scm_lazy_catch. These are wrappers for
5047 scm_catch_apply. scm_lazy_catch is intended to introduce catch
5048 handlers that run without popping the stack into the dynwind
5051 * throw.h: Added prototypes for scm_catch_apply and
5054 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5056 * root.h (scm_root, scm_set_root): Decouple thread support details
5057 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
5058 SCM_SET_THREAD_LOCAL_DATA.
5060 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
5061 and tortoise scanning loop.
5063 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
5065 * Makefile.in: Rebuild dependencies.
5067 * libguile.h: #include "libguile/print.h" before "smob.h", since
5068 the latter uses the print_state structure.
5070 * throw.c (scm_ithrow): Use the correct variable when checking to
5071 see if a given element of scm_dynwinds is a valid catch.
5073 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
5074 structure, abort; don't just silently ignore the garbage.
5076 * _scm.h: #include "print.h" here, since it seems to be used just
5078 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
5079 strports.c, unif.h: Don't #include "print.h".
5081 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5083 * feature.h (scm_loc_features): Removed external declaration.
5084 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5086 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5088 * feature.c (scm_init_feature): Added threads feature (needs to be
5089 initialized here, since features doesn't exist when
5090 scm_init_threads is called).
5092 * libguile.h: Added #include "libguile/../threads/threads.h".
5093 (This is a kludge to get thread support working. This should be
5096 * configure.in, acconfig.h: Added flags for thread support.
5098 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5101 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5102 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5105 * _scm.h: Added conditional #include "threads.h"
5107 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5108 SCM_THREADS_SWITCHING_CODE.
5110 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5111 allocate the basic dynamic root object.
5112 (scm_boot_guile): Added call to scm_init_root.
5114 * root.c, root.h: Added root smob.
5115 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5116 functions: Implements dynamic roots mostly according to spec in
5117 SCM manual. Main difference is that the second argument is a
5118 throw handler rather than an error "thunk".
5120 * root.h: Added declaration of scm_init_root.
5122 * root.c: Added #include "genio.h", #include "smob.h", #include
5123 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5125 (scm_init_root): Added #include "root.x".
5127 * throw.c: Added #include "stackchk.h"
5128 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5129 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5130 can be used in scm_call_with_new_root; Added reenabling of stack
5131 checking when catching a throw.
5133 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5135 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5137 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5138 element is not found, as per R4RS.
5140 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5142 * list.c: Doc fixes throughout.
5144 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5146 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5147 declare the char * to be const. Avoids a warning in rgx.c.
5149 * ports.h: spelling fix.
5151 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5154 * load.c (scm_sys_try_load_path): throw an error if file not found
5155 (like it says it in NEWS).
5157 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5159 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5160 PROPS slot to '(), not #f; it's an empty alist.
5162 * throw.h, throw.c: Use SCM_P instead of #if hair.
5164 Remove special support for uncaught throws; see throw.c for
5166 * throw.c (uncaught_throw): New function.
5167 (scm_ithrow): Call uncaught_throw if we don't find a throw
5168 target; don't mess with scm_bad_throw_vcell.
5169 (scm_bad_throw_vcell): Variable deleted.
5170 (scm_init_throw): Don't initialize it.
5172 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5175 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5177 * numbers.c (scm_istr2int): If the number is short (as most
5178 numbers are), just call scm_small_istr2int to deal with it.
5179 (scm_small_istr2int): New function, created by un-#ifdefing the
5180 non-bignum version of scm_istr2int and renaming it.
5182 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5184 * load.c (scm_sys_try_load): don't check whether value returned
5185 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5186 Change the Scheme name from %try-load to primitive-load.
5188 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5189 Can avoid passing a message, allowing it to be derived in the
5190 error handler (e.g., if we want to throw to the key both from
5193 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5195 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5196 references now have a new appearance which is more compact and
5197 also gives a clue about what the target of the reference is.
5198 By setting parameters in the print state, more fancy printing can
5199 be achieved. This is used by the (not yet commited) backtrace
5202 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5204 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5207 * print.c: Added #include "struct.h". Removed function
5210 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5211 scm_iprin1. Removed prototype for scm_prlist.
5213 * arbiters.c (prinarb),
5214 async.c (print_async),
5215 debug.c (prindebugobj, prinmemoized),
5216 eval.c (prinprom, prinmacro),
5217 filesys.c (scm_fd_print, scm_dir_print),
5219 mallocs.c (prinmalloc),
5220 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5221 smob.h (scm_smobfuns),
5222 srcprop.c (prinsrcprops),
5224 unif.c, unif.h (scm_raprin1, rapr1),
5225 variable.c (prin_var): Changed argument `int writing' to
5226 `scm_print_state *pstate'.
5228 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5229 that it will be called before scm_init_print.
5231 * print.c (scm_prin1): Print states are now allocated when calling
5232 scm_prin1 and then passed around to all printing functions as an
5233 argument. A cache `print_state_pool' enables reuse of print
5235 (scm_make_print_state): New function.
5236 (scm_iprin1): Adaption to print states.
5237 (scm_iprlist): An initial "hare and tortoise" scan brings down
5238 time complexity to O (depth * N). (Better time complexity will be
5239 achieved when the printing code is completely rewritten.)
5241 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5243 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5244 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5245 it gets done whether or not the cache variable has a value.
5247 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5249 Distinguish #f and ().
5250 * __scm.h: #undef SICP.
5251 * pairs.h (SCM_EOL): Delete this definition, equating it with
5253 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5254 the value it used to have. Doc fixes, too.
5256 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5258 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5259 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5260 Lord's implementation of structs, allowing for tail arrays as
5261 described in the manual. Also fixed some bugs. (Both the interface
5262 and the implementation should be improved.)
5264 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5266 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5267 People who whish to see the source can do `(print-enable 'source)'.
5268 Removed #ifdef DEBUG_EXTENSIONS.
5270 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5272 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5273 integer (assuming for now accepting an integer is a good thing).
5275 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5276 %S will be used instead for write'ing arguments.
5278 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5279 asserts. fix a few other asserts.
5280 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5281 scm_uniform_vector_ref, scm_array_set_x,
5282 scm_dimensions_to_unform_array): change args in
5283 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5284 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5285 scm_substring_fill_x): likewise.
5286 gsubr.c (scm_gsubr_apply): likewise.
5287 eval.c (SCM_APPLY): likewise.
5289 * eval.c (4 places): replace scm_everr with lgh_error or
5292 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5293 scm_memory_error): new procedures.
5294 scm_everr: deleted. can use scm_wta, dropping first two args.
5295 scm_error: convert NULL subr to SCM_BOOL_F.
5297 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5300 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5303 * error.c, error.h: new error keys: scm_arg_type_key,
5304 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5306 scm_wta: reimplement using lgh_error instead of scm_everr.
5308 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5310 * gdbint.c: scm_lread now has one more argument.
5312 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5313 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5314 loading source from non-file ports, which, e. g., happens when
5315 using the Emacs interface).
5317 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5320 * read.c: Added code for recording of positions of source code
5321 expressions; New functions: recsexpr, scm_lreadrecparen;
5322 _scm_make_srcprops --> scm_make_srcprops
5323 (scm_flush_ws): Removed updating of positions counters. This work
5324 is already done by scm_gen_getc
5326 * read.h: Added prototype for scm_lreadrecparen
5328 * print.c: Added #include "alist.h"
5330 * eval.c: Added #include "hash.h"
5332 * eq.c: Added #include "ramap.h"
5334 * options.c: Documentation fixes.
5336 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5337 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5338 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5339 --> scm_make_srcprops
5341 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5342 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5343 function calls in the definition of the whash access macros.
5345 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5347 * init.c (scm_boot_guile): Add level of indirection to
5348 scm_boot_guile_1() to ensure that stack base pointer is properly
5349 initialized. There was no guarantee that variable i was the
5350 highest/lowest variable on stack (i.e. the call frame of
5351 scm_boot_guile was not completely protected from gc).
5353 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5355 * ports.h (scm_port_table): put back file_name, it will be used to
5356 support debugging. Undo related changes in fports.c, ioext.c,
5359 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5361 * ports.h (scm_port_table): remove file_name member for now, it seems
5363 * fports.c (scm_open_file): don't set file_name in PTAB.
5364 (prinfport): don't use file_name in PTAB.
5365 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5366 * ports.c (scm_add_to_port_table): don't intialize file_name.
5367 (scm_port_file_name): remove for now.
5368 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5370 * fports.h (scm_mkfile): prototype deleted.
5371 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5373 * debug.c, unif.c: use scm_out_of_range instead of
5374 wta for range errors (ASSERT still needs work).
5376 * error.c, error.h (scm_out_of_range): new procedure.
5378 * error.c, error.h (scm_out_of_range_key): new key.
5380 * posix.c (scm_sync): #else was missing.
5382 * error.c, error.h: append _key to names scm_num_overflow and
5385 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5386 of consing an empty list.
5387 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5388 of macros, saves code and string space.
5389 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5390 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5391 lower case. Rename scm_syserror_m to scm_syserror_msg.
5392 error.h: prototypes for new procedures.
5394 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5396 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5398 * error.c, error.h: setup scm_num_overflow key.
5400 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5401 Remove definition of SCM_OVSCM_FLOW.
5403 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5405 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5406 explicit message and args.
5408 * error.c, error.h, __scm.h: change system_error_sym to
5411 * error.c (system_error_sym): remove leading %% from the Scheme name
5414 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5416 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5418 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5419 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5420 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5421 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5422 renamed. (These were introduced by unsupervised name
5425 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5427 * print.c: Added code for detection of circular references during
5428 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5429 a hook for printing of closures (accessible via print options).
5430 This leads to a split of calls to scm_iprin1 into two classes:
5431 elementary print operations (e. g. the code which prints a smob)
5432 still use scm_iprin1 while top level calls (like scm_display) use
5433 scm_prin1. scm_prin1 begins by clearing the data structure used
5434 to record reference information.
5436 * print.h: Added declarations of scm_prin1 and scm_prlist.
5438 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5440 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5442 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5444 * error.c (err_head): scm_iprin1 --> scm_prin1
5446 * debug.c: Adjusted header comment.
5450 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5452 * strerror.c: Doc fix.
5454 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5456 * gdbint.c (gdb_read): Now possible to run during GC.
5457 (unmark_port, remark_port): New functions.
5459 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5461 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5462 of allocating a new string object. Also, increase size by
5463 the factor 2 instead of 1.5.
5465 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5467 * __scm.h (SCM_P): Corrected to run under traditional C.
5469 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5472 * async.c: Calls to scm_sysintern corrected.
5474 * async.h (scm_async_clock): Redundant declaration removed.
5476 * continuations.c (scm_dynthrow): Redundant declaration removed.
5478 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5479 Definition typos corrected.
5481 * debug.h: Missing declarations of functions in debug.c added
5484 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5485 Missing declarations to functions in eval.c added.
5487 * filesys.c: Possibly uninitialized variable rv.
5489 * gc.h (scm_object_addr, scm_unhash_name): Missing
5490 declarations of functions defined in gc.c added.
5492 * genio.c: Possible typos str_data -> wstr_data. ???
5494 * genio.c: Possibly unintended shadowing of local variable
5495 `int c' (gotos out of scope of inner `c'). ???
5497 * init.c: Uninitialized `SCM last' may be used.
5499 * ioext.h: (scm_sys_isatty_p): Typo.
5501 * list.h (scm_list_head): Missing prototype for function in
5504 * numbers.c (scm_two_doubles): Changed from extern to static
5505 (is used only within numbers.c).
5507 * numbers.h: Repeated declarations removed.
5509 * ports.h (scm_close_all_ports_except): Declaration for the
5510 function defined in ports.c added.
5512 * posix.h: Missing declarations added.
5514 * procs.h (scm_make_subr_opt): Missing declaration added.
5516 * socket.h (scm_sys_gethost): Missing declaration added.
5518 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5520 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5521 Missing declarations added.
5523 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5525 * struct.c: Uninitialized variable `SCM answer' may be used.
5527 * unif.c (l2ra): Declaration prototype.
5529 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5530 defined in ramap.c).
5532 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5533 Redundant declarations removed (they are in ramap.h).
5535 * variable.h (scm_make_udvariable,
5536 scm_make_undefined_variable): Declaration corrected to
5537 correspond variable.c.
5539 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5540 Missing declarations added.
5542 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5544 * Makefile.in (distclean): Don't forget to delete fd.h.
5546 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5548 * fd.h.in, tags.h: Trivial cleanups.
5550 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5551 marksweep.h just declared functions from gc.c.
5552 * gc.h, libguile.h: Don't #include "marksweep.h".
5553 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5554 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5555 dependencies updated.
5557 * libguile.h: Don't #include "files.h"; it's been deleted.
5559 * files.c (scm_sys_delete_file): Moved to filesys.c.
5560 File is now empty; deleted.
5562 * filesys.c: scm_sys_delete_file is now here. Remove
5563 #if's; they seem to rely on remnants of an old portability
5564 regimen. If the problems come up again, solve them properly,
5565 using autoconf. Specifically: Don't test M_SYSV, and #define
5566 remove to be unlink if it's #defined; don't use remove just
5567 because HAVE_STDC_HEADERS is #defined.
5568 * filesys.h: Add declarations for scm_sys_delete_file.
5569 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5570 files.o, files.h, files.c, and files.x.
5571 * init.c: Don't #include "files.h", and don't call scm_init_files.
5573 Use SCM_P instead of PROTO; the latter intrudes on the user's
5575 * params.h: Deleted; definition of SCM_P moved to...
5576 * __scm.h: ... here, where it replaces PROTO macro.
5577 * libguile.h, smob.h: Don't #include "params.h".
5578 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5579 smob.h: Fix prototypes accordingly.
5580 * Makefile.in: Update dependencies.
5581 (inner_h_files): Remove params.h.
5583 * gc.c: #include "gc.h"; every module should include its header,
5584 to let the compiler cross-check the declarations against the
5587 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5588 simpos.h: #include "libguile/__scm.h".
5590 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5592 * init.c: Don't forget to #include smob.h and init.h.
5593 * Makefile.in: Dependencies updated.
5595 * smob.h: Use PROTO instead of #if __STDC__.
5597 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5599 * __scm.h: Doc fixes.
5601 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5602 <angles>; this allows `make depends' to work properly.
5604 * libguile.h: #include smob.h and pairs.h before the others; they
5605 define typedefs used by other headers.
5607 C files should #include only the header files they need, not
5608 libguile.h (which #includes all the header files); the pointless
5609 recompilation was wasting my time.
5610 * Makefile.in (all .o dependency lists): Regenerated.
5611 * libguile.h: Don't try to get a definition for size_t here...
5612 * __scm.h: Do it here.
5613 * _scm.h: Since this is the internal libguile header, put things
5614 here that all (or a majority) of the libguile files will want.
5615 Don't #include <libguile.h> here; that generates dependencies on
5616 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5617 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5618 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5715 * weaks.c: Get "weaks.h".
5717 * stackchk.h: #include "libguile/debug.h",
5719 * print.h, read.h: #include "options.h", since everyone who uses
5720 either of these files will need that.
5722 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5723 anyone who uses this file will need them to define the smob
5724 printing functions. Also, get markers.h, since people will need
5725 to #define the mark functions.
5727 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5728 * ports.h: ... to here.
5730 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5731 don't rely on archaic C default type rules.
5733 * fports.h: #include "libguile/ports.h", since you need that in
5734 order to parse this.
5736 * genio.h: #include "libguile/print.h", because you need that to
5737 parse this; don't bother #including "ports.h", since print.h gets
5740 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5742 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5743 this; it's now a reference to an element of *scm_root.
5745 * debug.h: Don't #include "options.h"; the compiler won't be able
5746 to find that once the headers are installed; instead, #include
5747 "libguile/options.h".
5748 * gc.h: Same, with marksweep.h.
5749 * mbstrings.h: Same, with symbols.h.
5750 * scmhob.h: Same, with _scm.h.
5751 * smob.h: Same, with params.h.
5753 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5754 C files; there's no need for this, and it forces recompilations
5757 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5759 * error.c (scm_error): declare scm_error_callback.
5761 * error.h: prototype for scm_error_callback.
5763 * __scm.h: define lgh_error.
5764 (SCM_SYSERROR): redefine using lgh_error.

5768 * error.c (scm_error): new procedure.
5770 * error.h: prototype for scm_error.
5772 * Makefile.in (install): install scmconfig.h from the current
5773 directory, not $(srcdir).
5775 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5777 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5778 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5779 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5780 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5781 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5782 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5783 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5784 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5785 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5786 vports.h, weaks.h: #include "libguile/__scm.h", not
5787 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5788 dependencies are within libguile properly.
5790 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5792 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5793 when scmconfig.h doesn't exist.
5795 * load.c (scm_sys_try_load): Correct spelling.
5797 * feature.c (scm_loc_features): Make this static.
5799 * Makefile.in (libpath.h): Omit trailing slash from path. We
5800 shouldn't require it of users, so why put it here?
5802 Move code to initialize and search %load-path from ice-9 to C
5803 code, so we can use the load-path to find the ice-9 boot code;
5804 this makes it easier to run Guile without installing it. See
5805 corresponding changes in guile/Makefile.in.
5806 * feature.c: Move stuff concerned with the load path to load.c.
5807 (scm_compiled_library_path): Deleted.
5808 Don't #include libpath.h here.
5809 * feature.h: Don't mention scm_compiled_library_path.
5810 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5811 <sys/stat.h>, and <unistd.h> (if present).
5812 (R_OK): #define if the system hasn't deigned to.
5813 (scm_loc_load_path): New variable.
5814 (scm_init_load_path, scm_sys_search_load_path,
5815 scm_sys_try_load_path): New functions.
5816 (scm_init_load): Initialize scm_loc_load_path to point to the
5817 value cell of the Scheme %load-path variable.
5818 * load.h: Add declarations for scm_sys_search_load_path,
5819 scm_sys_try_load_path.
5820 * init.c: Call scm_init_load_path.
5821 * Makefile.in (feature.o, load.o): Dependencies updated.
5823 * load.c, load.h: Rewrite using PROTO macro.
5825 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5827 * gc.c (scm_cellp): New function: C predicate to determine if an
5828 SCM value can be regarded as a pointer to a cell on the heap.
5830 * gc.h: Added declaration of scm_cellp.
5832 * gdb_interface.h: New file: The GDB interface header from the GDB
5835 * gdbint.c: New file: GDB interface.
5837 * gdbint.h: New file: GDB interface.
5839 * libguile.h: Added #include <libguile/gdbint.h>.
5841 * init.c (scm_boot_guile): Added scm_init_gdbint.
5843 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5844 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5845 found if object files and source are kept separate).
5847 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5849 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5851 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5853 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5854 TK_SRC_DIR; they're not relevant any more.
5856 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5857 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5859 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5861 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5862 search path, so we can find the <libguile/MUMBLE.h> headers.
5864 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5866 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5867 implicit in the .c.o rule.
5868 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5871 Put the library path in a header file, instead of passing it on
5872 the command line in every compilation.
5873 * Makefile.in (libpath.h): New target.
5874 (feature.o): Depend on libpath.h.
5875 (clean): Delete libpath.h.
5876 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5877 * feature.c: ... #include "libpath.h" here.
5878 * .cvsignore: Ignore libpath.h.
5880 Don't install the unwashed masses of Guile header files in the
5881 main #include path; put most of them in a subdirectory called
5882 'libguile'. This avoids naming conflicts between Guile header
5883 files and system header files (of which there were a few).
5884 * Makefile.in (pkgincludedir): Deleted.
5885 (innerincludedir): New variable; this and $(includedir) are enough.
5886 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5887 (installed_h_files): Divide this up. Now this variable lists
5888 those header files which should go into $(includedir) (i.e. appear
5889 directly in the #include path), and ...
5890 (inner_h_files): ... this new variable says which files appear in
5891 a subdirectory, and are referred to as <libguile/mumble.h>.
5892 (h_files): List them both.
5893 (install): Create innerincludedir, not pkgincludedir. Put
5894 the installed_h_files and inner_h_files in their proper places.
5895 (uninstall): Corresponding changes.
5896 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5897 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5898 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5899 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5900 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5901 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5902 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5903 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5904 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5905 vports.h, weaks.h: Find __scm.h in its new location.
5906 * __scm.h: Find scmconfig.h and tags.h in their new locations
5907 (they're both "inner" files).
5909 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5911 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5913 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5915 * posix.c: Doc fixes.
5917 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5919 * socket.c: Don't include a prototype for inet_aton; just use a
5920 K&R style declaration, to avoid warnings but minimize the chance
5921 of conflicts with the system.
5923 On NextStep, <utime.h> doesn't define struct utime, unless we
5924 #define _POSIX_SOURCE before #including it.
5925 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5926 * acconfig.h: New comment text for above CPP symbol.
5927 * configure.in: Call it.
5928 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5930 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5932 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5933 testing for __EMX__.
5935 * posix.c: #include <libc.h>, if it exists.
5937 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5938 don't even know if the latter exists.
5940 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5941 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5942 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5944 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5946 (scm_init_posix): Use them when initializing the Scheme constants
5949 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5951 * Makefile.in (libdir, includedir, bindir): Use the
5952 autoconf-supplied values, instead of deriving them ourselves.
5953 (pkgincludedir, datadir, pkgdatadir): New variables.
5954 (install, uninstall): Put the header files in a special
5955 subdirectory, not in the main search path.
5957 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5958 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5960 * Makefile.in (IMPLPATH): Deleted; never used.
5962 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5963 on the Tcl/Tk source any more.
5964 (INCLUDE_CFLAGS): Remove references to the above.
5966 * Makefile.in (version.o): Corrected dependencies.
5968 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5970 * libguile.h: #include "version.h"
5972 * init.c (scm_boot_guile): Call scm_init_version.
5973 * gscm.c (gscm_run_scm): Call scm_init_version.
5975 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5976 GUILE_VERSION): AC_DEFINE these.
5977 (acconfig.h): #undef the above symbols.
5979 * Makefile.in (libobjs): Add version.o.
5980 (installed_h_files): Add version.h.
5981 (c_files): Add version.c.
5982 (gen_c_files): Add version.x.
5983 (version.o): New rule.
5984 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5985 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5986 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5987 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5988 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5989 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5990 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5991 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5992 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5993 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5994 weaks.o): Add version.h to dependency lists.
5995 (markers.o): Remove duplicate rule.
5997 * version.h: New file.
5999 * version.c: New file.
6001 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6003 * symbols.c (scm_strhash): scm_downcase is now a function, not an
6004 array; use it appropriately. Since GCC is quite happy to
6005 subscript functions, it never warned us about this; we should use
6006 -Wpointer-arith in the future. I guess we never tested
6009 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6011 * socket.c: Doc and copyright fixes.
6013 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6015 * debug.c: Fixed and improved gdb support.
6017 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6019 * socket.c: Added declaration of inet_aton to avoid compiler
6020 warning. (Hope this solution is correct.)
6022 * stime.c: Added declaration of ftime. (This is missing in
6025 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
6027 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6029 * Makefile.in (c_files): add strerror.c.
6031 * strerror.c: new file from Emacs' sysdep.c.
6032 maybe configure should also check for sys_errlist.
6034 * configure.in (AC_REPLACE_FUNCS): add strerror.
6036 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6038 * debug.c (scm_init_debug): Added initialization for
6039 scm_evaluator_traps.
6041 * debug.h, debug.c: Various name changes.
6042 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
6043 "debug-options-interface". See commentary in options.c.
6045 * options.h, options.c: Options now have documentation strings.
6046 Also added a long explanatory commentary.
6048 * eval.c, print.h, print.c, read.h, read.c: Modifications to
6051 * gscm.c, init.c, root.c, throw.c: Bug fixes:
6052 last_debug_info_frame is now updated in all cases.
6054 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
6057 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6059 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
6060 Added option STACK_CHECKING.
6062 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6064 * Makefile.in: Added {debug,options,srcprop}.{h,c}
6066 * __scm.h: Removed symbols for debugging support.
6068 * acconfig.h: Added symbols for debugging support.
6070 * configure.in: Added user option for debugging support.
6071 --enable-debug will include the debugging code into libguile.a.
6073 * continuations.c (scm_make_cont): Enlarged the #if 0 around
6074 scm_relocate_chunk_to_heap.
6076 * debug.c: New file: low-level debugging support. It also
6077 includes support for debugging with gdb. (The extensions to gdb
6078 are written by Per Bothner at Cygnus.)
6080 * debug.h: New file: low-level debugging support.
6082 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6083 argument pairs. Extensive modifications to the debugging
6084 evaluator. Added "SECTION:" commentaries to clarify what happens
6085 when, during double compilation. Renamed EVALIMP --> EVALIM.
6086 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6087 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6088 the beginning of the file. New procedure: scm_unmemocopy.
6089 Added some global state variables needed by the debugging
6090 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6091 check_entry, check_apply, check_exit, debug_options and
6092 evaluator_traps. New acro: undefine.
6094 * eval.h: Renamed EVAL --> XEVAL.
6096 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6097 --> scm_make_weak_key_hash_table.
6099 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6100 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6102 * libguile.h: Conditionally include debug.h
6104 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6105 scm_object_properties shouldn't return handle. `handle' now gets
6106 initialized in scm_set_object_properties_x. scm_object_properties
6107 doesn't any longer create an entry in scm_object_whash.
6109 * options.c: New file: handling of run time options.
6111 * options.h: New file: handling of run time options.
6113 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6115 * print.c: New procedure: scm_print_options
6117 * print.h: Defines for print options.
6119 * read.c: New procedure: scm_read_options
6121 * read.h: Defines for reader options.
6123 * root.h: Added scm_source_whash among scm_sys_protects.
6125 * srcprop.c: New file: source properties.
6127 * srcprop.h: New file: source properties.
6129 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6130 (Bug found by A. Green.)
6132 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6134 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6136 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6138 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6140 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6141 and should be called by the final client.
6143 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6145 * gc.h: Use the PROTO macro when declaring functions.
6146 * gc.c: Use the PROTO macro when declaring static functions.
6147 Remove the CPP hair around function definitions.
6149 * gc.c (scm_init_storage): Initialize scm_asyncs.
6151 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6152 preprocessor symbol; "__scm.h" is where it might get #defined.
6153 * __scm.h: Similar: #include <scmconfig.h> before testing
6156 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6158 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6160 * init.c (scm_boot_guile): Add init_func argument; call
6161 (*init_func) instead of calling scm_appinit; it's ucky to
6162 hard-code names for the user's procedures.
6163 * init.h (scm_boot_guile): Adjust declaration.
6165 * __scm.h (PROTO): New macro, for declaring functions with
6168 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6169 eliminate all the __STDC__ conditionals.
6170 (scm_boot_guile): Add declaration.
6171 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6172 Remove __STDC__ conditionals around function definitions; the
6173 declarations in init.h will provide the same information, more
6176 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6177 complain about it in the error message; the error message is
6178 adequate without that note, and there's nothing the user can do
6181 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6183 * Makefile.in (ancillary): Drop def.sed.
6185 * posix.c (scm_init_posix): Use numeric values, rather than
6186 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6187 F_OK. The symbols aren't available on some systems, and I'm
6188 pretty sure their values are fixed by common widespread practice.
6189 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6191 More functions unavailable on some systems.
6192 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6193 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6195 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6196 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6197 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6198 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6199 stub that signals an error as the #else.
6201 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6203 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6205 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6207 * unif.c: include ramap.h.
6209 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6211 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6213 * ports.c: include sys/ioctl.h.
6215 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6217 * configure.in: check for sys/ioctl.h.
6219 * ports.c: include <malloc.h> not "malloc.h".
6221 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6223 * fports.c: remove ttyname and tmpnam declarations.
6225 * posix.c: fewer ttyname declarations.
6227 * fports.c: include <string.h> not "string.h".
6229 * init.c, ioext.c: include string.h and unistd.h.
6231 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6233 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6234 genio.c, simpos.c, vports.c: include string.h.
6236 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6238 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6240 (scm_addr_buffer_size): change type from scm_sizet to int.
6241 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6242 from scm_sizet to int.
6244 * error.c: include unistd.h.
6246 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6249 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6251 * __scm.hd, def.sed: deleted.
6253 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6255 Changes for NeXT, suggested by Robert Brown.
6256 * configure.in: Call AC_TYPE_MODE_T.
6257 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6258 NeXT. Put header file list in alphabetical order.
6259 * configure, scmconfig.h.in: Regenerated.
6260 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6262 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6265 * acconfig.h: New file, providing documentation for the CPP
6266 symbols defined in configure.in
6267 * acconfig-1.5.h: Removed; superceded by the above.
6269 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6271 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6273 * fports.c (scm_open_file): don't return #f, throw error.
6275 * ioext.c (fileno): renamed from %fileno.
6276 (soft-fileno): deleted.
6278 * ports.c (scm_port_revealed): don't need to check for -1 from
6280 (scm_set_port_revealed_x): return unspecified, not #f.
6282 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6284 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6286 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6288 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6290 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6292 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6293 This is necessary on Ultrix, and doesn't hurt portability.
6295 * Makefile.in (dist-dir): New target, implementing a new dist system.
6296 (installed_h_files): Put in alphabetical order.
6297 Remove duplicate entries for markers.h and unif.h.
6298 (c_files): Remove duplicate entries for markers.c.
6299 (ancillary): Renamed from anillery; all uses changed. Remove
6300 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6301 Remove all the ../doc/* files; doc/Makefile.in handles that.
6303 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6305 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6306 every if must have an else, or else the whole command has a
6307 non-zero exit code whenever the if's condition is false.
6309 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

6371 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6373 * ports.c (scm_ports_prehistory): size malloced here doesn't
6374 matter so long as it is non-0 (got rid of "* 4").
6376 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6378 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6379 since its definition was bogus).
6381 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6383 * mallocs.[ch]: back again (for rx at least).
6385 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6387 * ports.c: removed functions relating to the mapping between ports
6388 and descriptors. (That stuff is unix-specific and should be collected
6389 in a separate library).
6391 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6392 (Tom Mckay@avanticorp.com)

6396 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6397 handled correctly (SCM_FREEP was applied to them) -- test for
6398 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6399 being overwritten with #f. (brown@grettir.bibliotech.com)

6453 * ports.c (scm_add_to_port_table): Added fields
6454 to port table entries: file_name, line_num, col.
6455 Update these in open_file, gen_getc and gen_ungetc.
6456 Added procedures to access those fields.
6458 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

6566 initialization to fix a race condition.
6568 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6592 set the multi_byte flag correctly in symbols. This is wrong.
6593 intern_obbary_soft and msymbolize should take an extra parameter.
6594 Also, weird multibyte symbols don't print correctly.
6595 The weird symbol syntax is also a bit bogus (emacs doesn't quite
