87
88 * struct.c, struct.h:
89
90 In order to support different kinds of deallocation, a destructor
91 slot has been added to struct vtables. This allows for structs
92 containing pointers to other memory blocks.
93
94 (scm_struct_i_free): New hidden struct slot. Holds destructor for
95 instances to this vtable.
96 (scm_struct_free_0): New destructor: Doesn't deallocate data.

104
105 Changes to hidden slots:
106

108 scm_struct_i_size which holds the size of light structs.
109 (scm_struct_i_n_words): This slot has changed meaning. Previously
110 it included hidden slots. Now it indicates visible slots.
111 (scm_alloc_struct): Clear flags.
112 (SCM_STRUCTF_MASK): 4 new flag positions added => 12 bits.
113
114 (struct_num, scm_struct_i_tag): Removed.
115 (scm_struct_vtable_tag): Base tag on the pointer to mallocated
116 memory.

127 * gc.c (scm_gc_sweep): Call struct free slot.
128
129 * keywords.c, keywords.h (scm_c_make_keyword): New function.

133
134 * libguile.h: #include "objects.h"
135

137
138 * dynl.c (DYNL_GLOBAL): New.
139 (sysdep_dynl_link): Added `flags' argument.
140 (kw_global, sym_global): New.
141 (scm_dynamic_link): Handle keyword arguments. Pass suitable flags
142 to sysdep_dynl_link.
143 * dynl-dl.c (sysdep_dynl_link): Handle new `flags' argument by
144 conditrionally adding RTLD_GLOBAL to DLOPEN_MODES.
145 * dynl-shl.c (sysdep_dynl_link): Add and ignore new flags
146 argument.
147 * dynl-dld.c (sysdep_dynl_link): Add and ignore new flags
148 argument.

161 pointers. (Thanks to Mark Elbrecht.)
162
163 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
164
165 Patch from Greg Harvey:
166 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
167 around the condition of an `if', `while', etc., even if the
168 condition is a macro invocation that expands to something
169 surrounded by parens. It's more readable.
170
171 * eval.c (scm_map, scm_for_each): Verify that all arguments are
172 proper lists, and of the appropriate lengths.
173 (check_map_args): New function. (Thanks to Greg Harvey for the
174 bug report.)
175
176 1999-06-19 Michael Livshin <mike@olan.com>
177
178 * guardians.c (guardian_t): `next' - new field to be used for
179 chaining the live guardians in a single-linked list during the GC
180 mark phase.
181 (GUARDIAN_NEXT): convenience macro to access the `next' field.
182 (guardians, guardians_size, n_guardians): deleted.

188 (scm_guardian_zombify): iterate through the live guardian list.
189
190 (Applied by Jim Blandy.)
191
192 1999-06-16 Jim Blandy <jimb@savonarola.red-bean.com>
193
194 * gc.c (scm_mallocated): Just make this signed.
195 (scm_igc): Check for underflow by seeing if this is negative.
196 Much cleaner.
197 * gc.h (scm_mallocated): Fix declaration.
198 (Thanks to Greg Harvey.)
199
200 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.
201
202 1999-06-15 Jim Blandy <jimb@savonarola.red-bean.com>
203
204 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
205 sbd_time. (Thanks to Eric Hanchrow.)
206
207 Fix from Ken Raeburn <raeburn@raeburn.org>:
208 * weaks.c (scm_make_weak_vector): Add another extra slot before
209 vector contents, to be used only during garbage collection.
210 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
211 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
212 static.
213 (scm_weak_size, scm_n_weak): Deleted.
214 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
215 vectors without allocating new storage during GC, using
216 scm_weak_vectors as the head of the chain.
217 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
218 instead of stepping through an array.
219 (scm_gc_sweep): Update offset used to find start of weak vector to
220 free it.
221 (scm_init_storage): Set scm_weak_vectors to EOL.
222
223 Fix from Ken Raeburn <raeburn@raeburn.org>:
224 * gc.c (already_in_gc): New variable.
225 (scm_igc): Set and clear already_in_gc; abort if it's set at
226 entry.
227
228 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
229
230 Fix from Gary Houston:
231 * fports.c (local_seek): Signal an error if the seek fails.
232 * ports.c (scm_lseek): Don't check return value of port's seek
233 function; it's its job to signal an error if there's a problem.
234
235 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
236
237 * strports.c (scm_call_with_output_string): Don't include the
238 extra character at the end of the string in the result.
239
240 * ioext.c (scm_read_line): Switch to reading properly.
241
242 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
243 scmsigs.c, strports.c, vports.c: Install the sources which
244 actually correspond to the changes described below. I got the
245 ChangeLog entries and the patch from two different places...
246
247 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
248
249 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
250 it shows up as terrible performance, as we GC constantly.
251
252 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
253 newline. A bit faster, and definitely hairier.
254 (scm_read_line): Count newlines here instead.
255
256 * strings.c (scm_take_str): New function.
257 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
258 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
259 scm_take_str, to avoid copying the string.
260
261 Add some simple-minded support for line buffered ports.
262 * ports.h (SCM_BUFLINE): New flag for ports.
263 * init.c (scm_init_standard_ports): Request line-buffering on
264 the standard output port.
265 * * ports.c (scm_mode_bits): Recognize 'l' as a request for line
266 buffering.
267 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
268 and there's a newline to be written, flush the port.
269
270 Gary Houston's open-buffer port patches:
271
272 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
273
274 * ports.c: (scm_lseek): clear buffers even if just reading current
275 position.
276
277 * fports.c (local_fclose): call local_fflush unconditionally.
278 (various): don't use the scm_must... memory procs.
279
280 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
281
282 * ports.h (scm_port): make read_pos a pointer to const.
283 strports.c: take care of rw_active and rw_randow.
284 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
285 strports.c (scm_mkstrport): check that pos is reasonable.
286 ioext.c (scm_ftell, scm_fseek): use lseek.
287 (SCM_CLEAR_BUFFERS): macro deleted.

289 ports.h (scm_ptobfuns): add ftruncate.
290 ports.c (scm_newptob): set ftruncate.
291 adjust ptob tables.
292 * ports.c (scm_ftruncate): new procedure.
293 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
294 strports.c (st_seek, st_grow_port): new procs.
295 fports.h (scm_port): change size types from int to off_t.
296 ports.c (scm_init_ports): initialise the seek symbols here
297 instead of in ioext.c.
298 strports.c (scm_call_with_output_string): start with an empty
299 string, so seek and ftruncate can be used.
300
301 gdbint.c: adjust string port usage.
302
303 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
304
305 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
306 equivalent to fflush for the read buffer.
307 * ports.c (scm_newptob): set read_flush.
308 ports.c (void_port_ptob): set read_flush.
309 fports.c (local_read_flush): new proc. add to ptob.
310 strport.c (st_read_flush): likewise.
311 vport.c (sf_read_flush): likewise.
312 fports.h (struct scm_fport): remove random member. there's nothing
313 left but fdes. leaving it as a struct to allow for future changes.
314 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
315 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
316 ptob proc if the read buffer is filled.
317
318 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
319
320 * ports.h (scm_port): add a rw_random member and replace
321 reading and writing members with rw_active member.
322 SCM_PORT_READ/SCM_PORT_WRITE: new values.
323
324 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
325
326 * ports.h (struct scm_port_table): add writing and reading members
327 to replace write_needs_seek: it isn't good enough for non-fports.
328 ports.c, ioext.c, fports.c: corresponding changes.
329 (struct scm_port_table): give it a typedef and rename to scm_port.
330 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
331 corresponding changes.
332
333 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
334
335 * ports.c (scm_newptob): bugfix: set seek member.
336 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
337 and generalised to all port types.
338
339 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
340
341 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
342 signals (it was only being done for handlers installed from Scheme).
343 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
344 waiting for input caused an EINTR error from read.
345
346 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
347
348 * ports.h (struct scm_port_table): make all the char members
349 unsigned, so they convert to int without becoming negative if large.
350
351 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
352
353 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
354 with threads enabled. rename this procedure to
355 fport_wait_for_input and take a port instead of a fdes.
356 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
357
358 * readline.c (scm_readline): Applied a patch from Greg Harvey to
359 get readline support working again: use fdopen to get FILE objects.
360
361 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
362
363 * gc.c (scm_init_storage): install an atexit proc to flush the
364 ports.
365 (cleanup): the new proc. it sets a global variable which can be
366 checked by the ptob flush procs to avoid trying to throw
367 exceptions during exit. not very pleasant but it seems more reliable.
368 * fports.c (local_fflush): check terminating variable and if set
369 don't throw exception.
370 * CHECKME: that the atexit proc is installed if unexec used.
371
372 * throw.c (scm_handle_by_message): don't flush all ports here.
373 it still causes bus errors.
374
375 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
376 and move to ioext.c.
377
378 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
379
380 * ports.c (scm_char_ready_p): check the port buffer and call the
381 ptob entry if needed.
382
383 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
384 ptob initialisers. use it in char-ready
385
386 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
387
388 * vports.c (sfflush): modified to write a char (since softports
389 currently use shortbuf.)
390
391 * fports.c (scm_standard_stream_to_port): moved to init.c and
392 made static.
393
394 * init.c (scm_init_standard_ports): make stdout and stderr
395 unbuffered if connected to a terminal. with stdio they
396 were line-buffered by default.
397
398 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
399 update ptob tables.
400
401 * ports.h (scm_ptobfuns): change fflush return to void.
402 change flush proc definitions.
403
404 * strports.c (scm_call_with_output_string): get size from
405 buffer instead of port stream.
406 (scm_strprint_obj): likewise.
407 (st_flush): new proc.
408
409 * ports.h (struct scm_port_table): added write_end member,
410 as an optimisation. set it where write_buf_size is set.
411
412 * ports.h (struct scm_port_table): change stream from void *
413 back to SCM. SCM presumably must be large enough to hold a
414 pointer (and probably vice versa but who knows.)
415 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
416
417 (scm_puts): rewritten
418 * fports.c (local_ffwrite, local_fputs): removed.
419 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
420 * vports.c (sfputc, sfputs, sfwrite) likewise.
421 * ports.c (write_void_port, puts_void_port): removed.
422 (putc_void_port, getc_void_port, fgets_void_port): likewise.
423
424 * ports.c (scm_lfwrite): rewritten using fport.c version.
425
426 * fports.c (local_fputc): deleted.
427
428 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
429
430 * ports.h (scm_ptobfuns): add seek function pointer.
431 * fports.c: set it to local_seek, new procedure.
432
433
434 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
435 use ptob for seek. take ptob instead of fport arg.
436
437 * ports.h (struct scm_port_table): new member write_needs_seek,
438 replaces reading member in fport struct.
439
440 * vports.c (sfgetc): store the getted char into the buffer.
441 rename to sf_fill_buffer and install it for fill-buffer in ptob.
442 the Scheme interface is still a procedure that gets a char.
443 (scm_make_soft_port): set up the port buffer (shortbuf).
444
445 * fports.c (local_fgetc, local_fgets): deleted.
446 * strports.c (stgetc): likewise.
447 * ports.c: scm_generic_fgets: likewise.
448
449 * ports.h (scm_ptobfuns): add fill_buffer.
450 * ports.c (scm_newptob): assign it.
451 * strports.c (scm_mkstrport): set up the buffer.
452 put just the string into the stream, not cons (pos stream).
453 (stfill_buffer): new proc.
454
455 * ports.h: fport buffer moved into port table: to be
456 used for all port types.
457
458 1998-12-20 Gary Houston <ghouston@easynet.co.uk>
459
460 * throw.c (scm_handle_by_message): flush ports at exit.
461
462 * socket.c (scm_sock_fd_to_port): use scm_fdes_to_port.
463 (scm_getsockopt, scm_setsockopt, scm_shutdown, scm_connect,
464 scm_bind, scm_listen, scm_accept, scm_getsockname,
465 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
466 scm_sendto,
467 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.

650
651 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
652 error messages, not the uninitialized string `str'. Love that
653 typechecking.
654
655 * strop.c (scm_substring_move_x): New function, which can handle
656 arbitrary overlapping substrings.
657 (substring-move-left!, substring-move-right!): These are

674 versions.
675
676 1999-01-13 Greg Harvey <Greg.Harvey@thezone.net>

678 * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
679 changed to use memmove.

707
708 1999-04-17 Jim Blandy <jimb@savonarola.red-bean.com>

732
733 * numbers.c (isfinite): Define this macro if not defined: Return a
734 non-zero value if X is finite. (From ISO C 9x standard.)

738 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
739
740 * keywords.c (scm_tc16_kw): Added for backward compatibility.
741 Will be removed in next release.

775
776 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
777 scm_misc_error when pos is a string. This allows for dispatching
778 arbitrary error messages with one argument via SCM_ASSERT:
779 SCM_ASSERT (<cond>, obj, "Undigestable object: %S", <subr>);

788
789 Most of this batch of changes is about how to deal with extended
790 types when an object system is loaded into Guile. A nice object
791 system is capable of representing Guile's types as class objects.
792
793 For example, we want a regular expression to be of class <regex>.
794 But regular expressions are smobs which aren't under direct
795 control of the object system, so there has to be some mechanism
796 which informs the object system that a new class should be created
797 which can represent the smob type. I call this a "wrapper class".
798
799 * objects.c: #include "smob.h";
800 (scm_class_keyword): Removed. (Class is automatically created by
801 make_smob_classes.)
802 (scm_smob_class): Array of smob classes indexed by smobnum.
803 (scm_make_extended_class): "Plugin" function pointer for creation
804 of wrapper classes for smob and struct types.
805 (scm_class_of): Handle compiled closures. (Currently regarded as
806 <procedure>.);
807 Use scm_smob_class to handle smob types;
808 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
809 through scm_smob_class;
810 Handle structs.
811
812 * smob.c (scm_newsmob): Also create a wrapper class if
813 scm_smob_class has been initialized.
814
815 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
816 type code and smobnum.
817
818 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
819 (scm_struct_table): Weak key table with auxilliary information for
820 struct types. Currently used for names and wrapper classes.
821 (scm_struct_ihashq): Hash function for structs.
822 (scm_struct_create_handle): Get/create entry in scm_struct_table.
823 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
824 for accessing names of vtables. The record implementation in
825 boot-9.scm currently uses the setter to record the name of record
826 types. When the object system is initialized, it can use this
827 information to create wrapper classes with suitable names.
828 (scm_init_struct): Allocate scm_struct_table.
829 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
830 (struct tags are a finite resource and we might want to restrict
831 the use of tags to vtables only. E.g., Goops only uses tags for
832 classes.)
833 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
834 magic number 5.
835 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
836 number -1.
837
838 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
839 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
840 Used for access of struct table entries.
841
842 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
843 (scm_hash_fold): New procedure. Used to process all entries in a
844 hash table (in no particular order).
845
846 Argh! For the umpteenth time I got compilation errors because of
847 the "intuitive" name `kw'. This has to have an end:
848
849 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
850 "kw" --> "keywords" everywhere.
851 (I doubt that this will cause big compatibility problems since the
852 application interface is unaffected.)
853
854 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
855
856 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
857
858 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
859 column inums to native form.
860
861 Improvement of backtraces: Introduces a new stack narrowing
862 specifier, #t, for the inner cut. (See further in the comments in
863 stacks.c:narrow_stack ().)
864
865 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
866 (Used to flag certain system procedures which shouldn't turn up in
867 backtraces.)
868
869 * eval.c (scm_sym_system_module): New symbol. (Used to flag
870 modules which aren't "user" modules and the code of which
871 shouldn't turn up in backtraces.)
872
873 * eval.c, eval.h (scm_top_level_lookup_closure): New function:
874 Extract the lookup closure from an environment.
875 (scm_system_module_env_p): New function: Return non-#f if MODULE
876 is a system module.
877
878 * stacks.c: #include "eval.h"; #include "procprop.h";
879 (narrow_stack): Handle new narrowing specifier #t.
880
881 * debug.c (scm_procedure_name): Use name property in the default
882 case.
883
884 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
885
886 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
887
888 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
889 procedure throughout.
890
891 * print.c (scm_iprin1): Removed extraneous space when printing
892 procedure-with-setters.
893
894 Entity and operator setter slots were introduced as a complement
895 to the <procedure-with-setter> type in order to support entities
896 and operators with setters in a reasonable and efficient way.
897 * procs.c (scm_procedure, scm_setter): Handle entity and operator
898 setter slots.
899
900 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.
901 (struct scm_metaclass_operator): New setter slot.
902
903 * gc.c (scm_gc_mark): Mark struct setter slot.
904
905 * struct.c (scm_make_struct): Allocate one word more for
906 entities and initialize the new slot.
907
908 * struct.h (scm_struct_i_setter): New constant.
909
910 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
911
912 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
913 directly through the instance.
914
915 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
916
917 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
918 scm_struct_i_flags instead of scm_vtable_index_layout!
919
920 * list.c (scm_list_star): New procedure.
921
922 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

937 structure. (Thanks to Michael Livshin.)
938
939 1999-02-06 Jim Blandy <jimb@savonarola.red-bean.com>
940
941 Readline paren matching from Greg Harvey, with modifications from
942 Mikael Djurfeldt:
943
944 * readline.c (in_readline, reentry_barrier_mutex): Make these
945 static.
946
947 * readline.c: #include <sys/time.h> and "iselect.h", so we can
948 control how long we're paused, and threads will run while we're
949 paused.
950 (match_paren, find_matching_paren, init_bouncing_parens): New
951 functions.
952 (scm_init_readline): Call init_bouncing_parens.
953 (scm_readline_opts): Add the bounce-parens option.
954 * readline.h (SCM_READLINE_BOUNCE_PARENS): New readline option.
955 (SCM_N_READLINE_OPTIONS): Adjust.

957 1999-02-06 Jim Blandy <jimb@zwingli.cygnus.com>
958
959 All the below are changes from Ken Raeburn, to get Guile to use
960 const where it can.

1002 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
1003 SYMB now point to const.
1004
1005 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1006
1007 * print.c (scm_iprin1): Use scm_procedure_name instead of
1008 scm_procedure_property for compiled closures.
1009
1010 * tags.h (scm_tc7_pws): New procedure type. Four representations
1011 for procedure-with-setters were considered before selecting this
1012 one:
1013
1014 1. A closure where the CODE and ENV slots are used to represent
1015 the getter and a new SETTER slot is used for the setter. The
1016 original getter is stored as a `getter' procedure property. For
1017 closure getters, the CODE and ENV slots contains a copy of the
1018 getter's CODE and ENV slots. For subr getters, the CODE contains
1019 a call to the subr.
1020
1021 2. A compiled closure with a call to the getter in the cclo
1022 procedure. The getter and setter are stored in slots 1 and 2.
1023
1024 3. An entity (i.e. a struct with an associated procedure) with a
1025 call to the getter in the entity procedure and the setter stored
1026 in slot 0. The original getter is stored in slot 1.
1027
1028 4. A new primitive procedure type supported in the evaluator. The
1029 getter and setter are stored in a GETTER and SETTER slot. A call
1030 to this procedure type results in a retrieval of the getter and a
1031 jump back to the correct eval dispatcher.
1032
1033 Representation 4 was selected because of efficiency and
1034 simplicity.
1035
1036 Rep 1 has the advantage that there is zero penalty for closure
1037 getters, but primitive getters will get considerable overhead
1038 because the procedure-with-getter will be a closure which calls
1039 the getter.
1040
1041 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1042 <procedure-with-setter>, but together with rep 2 it suffers from a
1043 three level dispatch for non-GOOPS getters:
1044
1045 cclo/struct --> dispatch proc --> getter
1046
1047 This is because the dispatch procedure must take an extra initial
1048 argument (cclo for rep 2, struct for rep 3).
1049
1050 Rep 4 has the single disadvantage that it uses up one tc7 type
1051 code, but the plan for uniform vectors will very likely free tc7
1052 codes, so this is probably no big problem. Also note that the
1053 GETTER and SETTER slots can live directly on the heap, using the
1054 new four-word cells.
1055
1056 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1057 SCM_SETTER): New macros.

1064 scm_tc7_pws.
1065
1066 * objects.c, objects.h (scm_class_of,
1067 scm_class_procedure_with_setter): Added.

1117
1118 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1119 different order if the machine is bigendian.
1120 (scm_init_random): Added safety check for bignum digit size.
1121
1122 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>

1127 function call are executed in a well defined order.
1128
1129 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1130
1131 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1132 Christian Lynbech.)
1133
1134 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1135
1136 * random.c: Removed alloca includes.
1137
1138 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1139
1140 * Makefile.in: This changed, for some reason I don't really
1141 understand, when I ran automake in the top level directory. This
1142 may be contamination by Cygnus internal releases. If you re-run
1143 automake and this change gets reverted, don't worry about it.
1144
1145 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1146
1147 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1148 interfaces. Author: Roland Orre.

1150 * Makefile.am: Added sort.c, sort.h, sort.x.
1151
1152 * init.c: #include "sort.h";

1154
1155 * numbers.h: Added #include "libguile/print.h".
1156
1157 * numbers.c: Formatted according to Guile conventions;
1158 Renamed s_bignum --> scm_s_bignum.
1159
1160 * random.c, random.h: New files: Random number support.
1161 Interface same as slib's.
1162

1164
1165 * init.c: #include "random.h";

1167
1168 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1169

1175 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1176 David Eby (1993) "Guardians in a Generation-Based Garbage
1177 Collector" ACM SIGPLAN Conference on Programming Language Design
1178 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1179 /pub/scheme-repository/doc/pubs/guardians.ps.gz

1183
1184 * gc.c (scm_igc): Call scm_guardian_gc_init and
1185 scm_guardian_zombify.
1186
1187 * init.c (scm_boot_guile_1): Call scm_init_guardian.
1188
1189 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1190
1191 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1192 argument checking.
1193
1194 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1195
1196 Move the procedure slots of entities to invisible slots (so that
1197 we can have operator class objects which themselves are entities).
1198 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1199 SCM_STRUCTF_ENTITY): New constants.
1200
1201 * struct.c (scm_make_struct): Allocate "invisible" room for
1202 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1203
1204 * gc.c (scm_gc_mark): Mark entity procedures.
1205
1206 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
1207 and made global.
1208 (scm_struct_init): Renamed from init_struct and made global.
1209
1210 * objects.h (SCM_ENTITY, scm_entity): Removed.
1211 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1212 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1213
1214 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1215
1216 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1217 of syntactic forms, similar to SCM_PROC.
1218 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1219 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1220 for the name symbols when needed.
1221
1222 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1223
1224 * Makefile.in: Regenerated.
1225
1226 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1227
1228 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1229 take the address of _into; it might be a register. Just have
1230 scm_debug_newcell return the new cell.
1231 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1232 taking the address of a place to store it as an argument.
1233 * gc.h (scm_debug_newcell): Change declaration.
1234 (Thanks to Greg Harvey.)
1235
1236 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1237
1238 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1239 Replaces old names serial-array-copy! and serial-array-map!.
1240
1241 * evalext.c (map-in-order): New name. Replaces serial-map.
1242
1243 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
1244
1245 * smob.c (freeprint): New function.
1246 (freecell): Use it to print freed objects, for slightly easier
1247 debugging.
1248
1249 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1250
1251 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1252 error if no source properties can be found for a frame. (Thanks
1253 to Christian Lynbech.)
1254
1255 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1256
1257 * objects.h: Removed slots direct_supers and direct_slots from the
1258 definitions of the rudimentary classes described by objects.h.
1259
1260 * objects.c, objects.h (scm_entity_p): New procedure. Together
1261 with the predicates scm_procedure_p and scm_struct_p, this
1262 predicate makes it possible to differ between structs, entities
1263 and operators.
1264
1265 * modules.c, modules.h (scm_resolve_module): New function.
1266
1267 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1268
1269 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1270 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1271 `direct_slots'.
1272
1273 * objects.c (scm_entity_p): New procedure.
1274
1275 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1276 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1277
1278 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1279
1280 * procprop.h (scm_i_procedure_arity): Added declaration.
1281
1282 * procprop.c (scm_i_procedure_arity): Made global; New code to
1283 handle operators and entities.
1284 (scm_procedure_property): No need to call scm_procedure_p since
1285 scm_i_procedure_arity now does all necessary type checking.
1286 Added #include "objects.h".
1287
1288 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1289 s_add_hook_x --> s_remove_hook_x.
1290 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1291 Added #include "procprop.h"
1292
1293 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1294 (scm_make_hook): Optional argument defines number of arguments to
1295 the hook.
1296 (scm_make_named_hook): Take number of args as second arg.
1297 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1298 boot-9.scm for a while); First arg is the hook. The rest are
1299 arguments passed on to the hook procedures.
1300
1301 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1302
1303 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1304 scm_logbit_p): Do the computation in ulongs. This is not as nice
1305 as doing it in bignums, but at least it's good enough for
1306 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1307
1308 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1309 subexpressions. (Thanks to Charbel Jacquin.)
1310
1311 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1312
1313 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1314 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1315 (scm_make_named_hook): New function.
1316
1317 * feature.c: Added #include "eval.h".
1318
1319 * modules.c (scm_make_module): Beautify the module.
1320
1321 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1322
1323 * modules.c, modules.h: New files: C interface to modules. (This
1324 is necessary in order to interface the object system to Guile
1325 properly. The guts of these modules will be replaced by the new
1326 module system in the future.)
1327
1328 * init.c: Added #include "modules.h"
1329 (scm_boot_guile_1): Call scm_init_modules.
1330 (invoke_main_func): Call scm_post_boot_init_modules.
1331
1332 * Makefile.am: Added modules.c, modules.x, modules.h.
1333
1334 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1335
1336 * procs.c: #include "objects.h"
1337 (scm_procedure_p): Return #t also on structs which are operators.
1338
1339 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1340 <operator-metaclass> and <entity-class> to <standard-class>,
1341 <operator-class> and <entity> in order to conform with STKlos
1342 naming conventions.
1343
1344 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1345 which isn't an operator.
1346 (SCM_APPLY): Ditto, but jump to badproc.
1347
1348 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1349
1350 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1351 Previously, structs implanted in code were interpreted as forms
1352 the operator of which was a gloc. We solve this by checking for
1353 the zero in the emulated vcell in the struct vtable. Since
1354 implanted structs always will look like forms with a gloc
1355 operator, execution will only be slowed down by maximally one
1356 extra test-and-branch per application.
1357
1358 * evalext.c (scm_definedp): Removed check for isyms; Added a
1359 second optional argument: It is now possible to supply an
1360 evaluation environment in which to look for the symbol.
1361
1362 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1363
1364 * readline.c (scm_init_readline): Set
1365 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1366
1367 * coop.c (coop_condition_variable_wait): Removed
1368 (coop_condition_variable_wait_mutex): Folded logic of
1369 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1370 prevent condvar signal lossage. Previously, another thread could
1371 start to run after unlocking the mutex but before putting the
1372 current thread on the wait queue. If that thread then would
1373 signal the first, the signal would be lost. (Thanks to Christian
1374 Lynbech.)
1375
1376 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1377
1378 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1379 Christian Lynbech.)
1380
1381 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1382
1383 * objects.c (scm_i_make_class_object): Renamed from
1384 make_class_object; exported; error checking moved to
1385 scm_make_class_object and scm_make_subclass_object.
1386 (scm_make_class_object, scm_make_subclass_object): Use
1387 scm_i_make_class_object.
1388 (scm_make_subclass_object): Let the subclass have same metaclass
1389 as the superclass.
1390
1391 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1392
1393 * debug.c (scm_debug_options): Bugfix: Set the value of
1394 scm_stack_checking_enabled_p after setting debug options;
1395 #include "stackchk.h". (Thanks to Richard Polton.)
1396
1397 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1398
1399 * unif.c (scm_array_contents): removed unnecessary test for 0
1400 base.
1401
1402 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1403
1404 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1405 Replaced by macro `collect' in boot-9.scm.
1406
1407 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1408
1409 * eval.c (scm_copy_tree): Copy source properties if existent.
1410
1411 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1412 don't, we may end up passing memoized source to a transformer.)
1413
1414 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1415
1416 * stack.c (get_applybody): Help function which lookups the first
1417 body form of the apply closure.
1418 (read_frames): Prevent the source of the first form of the apply
1419 closure from being recorded. This would only be confusing.
1420
1421 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1422 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1423
1424 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1425
1426 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1427 statement.
1428 (read_frames): Use SCM_MACROEXPP.
1429
1430 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1431
1432 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1433 don't contain interesting information since all arguments are
1434 present in the frame which applies the compiled closure anyway.);
1435 Skip the transformer application frames.
1436
1437 * print.c (scm_iprin1): Print gsubrs as primitives.
1438
1439 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1440
1441 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1442
1443 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1444 that we can identify these in a backtrace. (This change doesn't
1445 introduce any significant speed penalty.)
1446
1447 * eval.c: Added note about `serial-map' using scm_map.
1448
1449 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1450 readline options. They should reside in their own options array.
1451
1452 * readline.c, readline.h (scm_readline_options,
1453 scm_readline_opts): Moved readline options here.
1454
1455 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1456
1457 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1458 SCM_ROCHARS instead of SCM_CHARS.
1459
1460 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1461 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1462
1463 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1464
1465 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1466 This is quite important since the latter clears the
1467 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1468 every single character read...
1469
1470 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1471
1472 * print.c (scm_iprin1): Removed suspect looking (and indeed
1473 malevolent) semicolon after test for user supplied closure print
1474 procedure. (Thanks to Telford Tendys.)
1475
1476 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1477 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1478 starting to search the list. Removed call to sloppy_mem_check.
1479
1480 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1481 procedures: Same as scm_delq_x et al, but delete maximally one
1482 element.
1483
1484 * options.c (scm_options, scm_init_options): GC-protect option
1485 values of type SCM. (Thanks to Telford Tendys.)
1486
1487 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1488
1489 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1490 make sure that there always is a "real" scm_lookupcar.
1491
1492 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1493
1494 * read.c, read.h (scm_read_opts): New read options
1495 "history-length" and "history-file".
1496 (scm_read_options): Stifle history to history length.
1497
1498 * readline.c (scm_read_history, scm_write_history): New procedures.
1499
1500 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1501
1502 * eval.h (scm_macro_eval_x): Removed declaration.
1503
1504 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1505 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1506 Renamed and made global.
1507
1508 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1509 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1510
1511 * evalext.c, evalext.h: New files. Contain non-R5RS things
1512 having to do with evaluation.
1513
1514 * evalext.c (scm_serial_map): New procedure: Version of `map'
1515 which guarantees that the procedure is applied to the lists in
1516 serial order.
1517 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1518 returns a list of the results of the body forms instead of the
1519 result of the last body form.
1520 (scm_definedp, scm_m_undefine): Moved from eval.c
1521
1522 * evalext.h (scm_m_sequence_to_list): Added declaration.
1523
1524 * macros.c, macros.h: New files.
1525 (scm_procedure_to_syntax, scm_procedure_to_macro,
1526 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1527 scm_macro_name, scm_macro_transformer): Moved from eval.c
1528 (scm_make_synt): Moved from eval.c
1529
1530 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1531
1532 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1533 scm_init_evalext.
1534
1535 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1536
1537 * debug.c, print.c: Added #include "macros.h".
1538
1539 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1540
1541 This change adds the ability to use `unread-char' multiple times
1542 without interspersed reads and adds the new procedure
1543 `unread-string'. The change is optimized for the common case of
1544 unreading a single character. This is also the reason behind the
1545 choice to store characters in the port itself: in most cases no
1546 extra malloc is required.
1547
1548 The amount of code in some macros in ports.h has been increased to
1549 the extent that they would fit better as C functions, but, since
1550 this code belongs to the port representation, such functions
1551 should be placed in ports.c which would cause calls back and forth
1552 between ports.c and genio.c. That is not good for performance.
1553 Also, keeping them as macros allows the compiler to do some
1554 optimizations which are needed to make the current interface
1555 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1556
1557 One benchmark (Guile startup time) indicates an increase of
1558 loading speed of 1%. Another (reading (using `read') boot-9.scm
1559 10 times) shows no change in performance.
1560
1561 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1562 made to find a beautiful solution.)
1563
1564 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1565 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1566 character. (SCM_CLRDY clears all.)
1567 (SCM_N_READY_CHARS): New macro: Returns number of unread
1568 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1569 (struct scm_port_table): New fields: `entry' contains port table
1570 index, `cp' points to last unread char, `cbuf' is the buffer for
1571 unread chars, `cbufend' points after end of the character buffer.
1572
1573 * ports.h, ports.c (scm_unread_string): New procedure.
1574 (scm_grow_port_cbuf): New function.
1575
1576 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1577 Handle new fields.
1578 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1579 to read unread characters. Use SCM_TRY_CLRDY instead of
1580 SCM_CLRDY.
1581
1582 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1583
1584 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1585
1586 * genio.c, genio.h (scm_ungets): New function.
1587
1588 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1589 sections.
1590
1591 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1592
1593 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1594 declarations. (Thanks to Russ McManus.)
1595
1596 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1597
1598 * numbers.c (num2long): As a software archeologist, I'm proud of
1599 this finding! :) Preliminary dating suggests an almost 4 year old
1600 remnant from the SCM ancestor. The sample has been removed from
1601 the finding site and is now safely stored in the repository.
1602
1603 * numbers.h: Removed prototype for num2long.
1604
1605 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1606
1607 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1608 array as second arg.
1609 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1610 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1611 * gh.h: Updated and added prototypes.
1612
1613 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1614
1615 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1616
1617 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1618
1619 * guile-snarf.in: Never generate an empty file. (Thanks to
1620 Richard Polton.)
1621
1622 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1623 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1624 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1625 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1626 gh_new_procedure5_0): Specify argument types, to appease C++
1627 compilers. (Thanks to Brad Bowman.)
1628
1629 Bug reports from Russ McManus:
1630 * guile-snarf.in: If the CPP environment variable is set, use that
1631 as the C preprocessor, instead of the preprocessor autoconf
1632 found.
1633 * snarf.h (SCM_PROC): Cast the function pointer passed to
1634 scm_make_gsubr, to satisfy C++.
1635
1636 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
1637 Use the handler passed, instead of ignoring it and using
1638 gh_standard_handler. (Thanks to Etienne Bernard.)
1639
1640 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
1641
1642 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
1643 Neuss.)
1644
1645 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

1663 copyright years.
1664
1665 * script.c (scm_compile_shell_switches): Define
1666 use-emacs-interface in the root module, so the repl code can see
1667 it. See today's change to top-repl in ice-9/boot-9.scm.
1668
1669 * filesys.c (set_element, get_element): Make sure that `element'
1670 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
1671 Boekemeier and Jorgen "forcer" Schaefer.)
1672
1673 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
1674
1675 * chars.c (scm_charnames): In ASCII character name table, make
1676 newlines print as #\newline by default, not #\nl.
1677
1678 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
1679 alphabetical order. Oh thrills. But it helps me know how far
1680 along in the compilation I am.
1681 * Makefile.in: Regenerated.
1682
1683 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1684
1685 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
1686 #bytes(...) to #y(...), and syntax for short vectors from
1687 #short(...) to #h(...). This may seem nutty, but, like the other
1688 uniform vectors, byte vectors and short vectors want to have the
1689 same print and read syntax (and, more basic, want to have read
1690 syntax!). Changing the read syntax to use multiple characters
1691 after the hash sign breaks with the conventions used in R5RS and
1692 the conventions used for the other uniform vectors. It also
1693 introduces complexity in the current reader, both on the C and
1694 Scheme levels. (The Right solution is probably to change the
1695 syntax and prototypes for uniform vectors entirely.)
1696
1697 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
1698
1699 Don't use local_fgets on sockets; ftell doesn't work on sockets.
1700 (Thanks to Jorgen "forcer" Schaefer.)
1701 * ports.h (SCM_NOFTELL): New flag.
1702 * fports.c (local_fgets): If it's set, use the generic fgets.
1703 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
1704
1705 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1706
1707 * script.c (scm_compile_shell_switches): Add handling of -q switch
1708 (inhibit loading of user init file).
1709 (scm_shell_usage): Add usage text for -q switch.
1710 (scm_compile_shell_switches): Always load user init file first if
1711 it is loaded at all.
1712
1713 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
1714
1715 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
1716 and is now broken under NetBSD. I can't fathom what it's trying
1717 to do, so I've replaced it with something that I do understand,
1718 which seems to work, and which isn't broken on NetBSD. "Progress?
1719 You Decide." (Thanks to Perry Metzger.)
1720
1721 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
1722 signed/unsigned comparison.
1723
1724 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
1725
1726 Warning fixes from Greg Harvey:
1727 * unif.c (scm_array_set_x): initializer for pos
1728 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
1729 * struct.c (scm_struct_ref, scm_struct_set_x): Added
1730 initializers for field_type, since EGCS so desparately wants to
1731 play dumb
1732 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
1733 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
1734 when GUILE_DEBUG is defined.
1735 * dynwind.h (scm_wind_chain): Same.
1736 * ports.h (scm_pt_size, scm_pt_member): Same.
1737 * print.h (scm_current_pstate): Same.
1738 * procs.h (scm_make_cclo): Same.
1739
1740 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
1741
1742 Handle short and long long uniform arrays properly. (Thanks to
1743 Clark McGrew.)
1744 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
1745 raeql_1): Add cases for scm_tc7_svect (short vectors) and
1746 scm_tc7_llvect (long long vectors).
1747
1748 Change the way libguile and boot-9.scm are timestamped, to try to
1749 get rid of these spurious mismatch warnings. Now both
1750 libguile/versiondat.h and ice-9/version.scm are generated directly
1751 by the configuration process, rather than having version.scm
1752 generated directly, and libguile/versiondat.h generated by the
1753 Makefile, which is generated by configure. It seems that
1754 sometimes the Makefile would change, but versiondat.h depends on
1755 Makefile.in, not Makefile, so it wouldn't get rebuilt.
1756 * Makefile.am (versiondat.h): Target removed; this is generated
1757 directly by the configure script now.
1758 (BUILT_SOURCES): Remove versiondat.h.
1759 * versiondat.h.in: New file, transformed by the configure script
1760 into versiondat.h.
1761 * Makefile.in: Regenerated.
1762
1763 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
1764 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
1765 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
1766 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
1767 if we want to use them in a header file some day, we can. (Thanks
1768 to Michael Livshin.)
1769
1770 * stime.c (scm_get_internal_real_time): Do the arithmetic using
1771 SCM numbers, so we won't have rollover problems; the range of a
1772 signed long in milliseconds is about 25 days. (Thanks to Karl
1773 Hegbloom.)
1774
1775 Don't redefine sleep and usleep; fix this problem now.
1776 * coop.c (sleep, usleep): Remove declarations; we don't use or
1777 redefine these any more.
1778 (scm_thread_usleep, scm_thread_sleep): New functions which do the
1779 job of usleep and sleep in a thread-friendly way. We can use
1780 these in the rest of Guile. Define versions for systems both with
1781 and without iselect.
1782 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
1783 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
1784 we're just using it, not redefining it, we can use a K&R style
1785 declaration here.
1786 (sleep): Declare this, too, if the system hasn't.
1787 (scm_sleep, scm_usleep): Use scm_thread_sleep and
1788 scm_uthread_sleep if they're available; otherwise, just call the
1789 system functions.
1790 * scmconfig.h.in: Regenerated.
1791
1792 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
1793
1794 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
1795
1796 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
1797
1798 * threads.c: Doc fix.
1799
1800 The argument type of usleep varies from system to system,
1801 as does the return type. We really shouldn't be redefining usleep
1802 at all, but I don't have time to clean that up before the 1.3.
1803 release. It's on the schedule for afterwards. (Thanks to Julian
1804 Satchell.)
1805 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
1806 definition.
1807 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
1808 * scmconfig.h: Regenerated.
1809
1810 * simpos.c (scm_software_type): Procedure deleted. This isn't the
1811 right way to handle system variation. Autoconf's approach is the
1812 way and the light.
1813 * simpos.h (scm_software_type): Declaration deleted.
1814
1815 * script.c (scm_find_executable): Don't test if unix is #defined
1816 here; first, NetBSD doesn't #define it, and second, it's the wrong
1817 way to go about these things. (Thanks to Perry Metzger.)
1818 (dld_find_executable): Delete this MSDOS support code. This isn't
1819 the way we want to support this; it needs to be rethunk at a
1820 larger scale.
1821
1822 * genio.c (scm_do_read_line): Don't just politely check that the
1823 line was either non-empty or EOF. Abort if it's empty and not
1824 EOF.
1825
1826 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
1827
1828 * scmconfig.h.in: Regenerated.
1829
1830 * libguile.h: Don't omit the dynamic linking functions. (Thanks
1831 to Greg Badros.)
1832
1833 * genio.c (scm_do_read_line): Count lines correctly when the file
1834 doesn't end in a newline.
1835
1836 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
1837
1838 * genio.c (scm_do_read_line): Maintain the line count correctly.
1839 (Thanks to Harvey J. Stein and Greg Harvey.)
1840
1841 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
1842 requires ANSI now.
1843
1844 * numbers.c (big2str): Protect t from garbage collection until
1845 we're done. (Thanks to Gary Houston.)
1846
1847 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
1848
1849 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
1850 version number.
1851 * Makefile.in: Regenerated.
1852
1853 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
1854 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
1855 SCM_P macro.
1856
1857 Do magic to mix reads and writes on stdio FILE-based ports.
1858 (Thanks to Christian Lynbech.)
1859 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
1860 New macros.
1861 (pre_read, pre_write): New functions.
1862 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
1863 local_fputs): Call them.
1864 (local_fflush): Mark the port as ready for reading and writing.
1865 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
1866 flags on new port objects. This might not be accurate --- who
1867 knows what state the FILE * is in when we get it --- but it won't
1868 do extraneous calls to fflush or fseek, so it's no worse than the
1869 behavior before this change.
1870 * ports.h: Add comment.
1871
1872 Centralize the creation of port objects based on stdio FILE * in
1873 fports.c; don't just throw them together anywhere.
1874 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
1875 what the rest of Guile wants. Don't set the revealed count;
1876 that's only appropriate for stdin, stdout, stderr.
1877 (scm_standard_stream_to_port): This function does set the revealed
1878 count.
1879 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
1880 not scm_stdio_to_port.
1881 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
1882 * fports.c (scm_open_file): Same.
1883 * posix.c (scm_pipe): Same.
1884 * socket.c (scm_sock_fd_to_port): Same.
1885 * ioext.c (scm_fdopen): Same.
1886 (scm_freopen): Moved from here to...
1887 * fports.c (scm_freopen): ... here. This is really something that
1888 munges the internals of an fport, so it should go here.
1889 * fports.h (scm_stdio_to_port): Adjust prototype.
1890 (scm_standard_stream_to_port, scm_freopen): New protoypes.
1891 * ioext.h (scm_freopen): Prototype removed.
1892
1893 * filesys.c (set_element, get_element): This can work on both pipe
1894 and file ports, so use SCM_FPORTP to typecheck, instead of testing
1895 for scm_tc16_fport.
1896
1897 * scmconfig.h.in: Regenerated.
1898
1899 Change the definition of the functions in scm_ptobfuns so that
1900 they get passed the port object, not the port's stream.
1901 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
1902 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
1903 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
1904 Pass the port itself to the scm_ptobs function.
1905 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
1906 scm_generic_fgets): Same.
1907 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
1908 getc_void_port, fgets_void_port, close_void_port): Just change the
1909 argument names; these functions don't really do anything.
1910 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
1911 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
1912 port as an argument, and use SCM_STREAM to get the stdio FILE *.
1913 Also, use prototyped definitions, and get rid of the extra
1914 declarations.
1915 (scm_fptob, scm_pipob): We don't need casts here any more.
1916 * strports.c (prinstpt): Use prototype declarations.
1917 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
1918 and use SCM_STREAM to get the string info. Also, use prototyped
1919 definitions, and get rid of the extra declarations.
1920 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
1921 noop0): Same.
1922
1923 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
1924 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
1925
1926 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
1927 scm_fgets, for consistency.
1928 (scm_fptop, scm_pipob): References updated.
1929
1930 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
1931
1932 Include the source location in error messages for scripts.
1933 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
1934 stack is still there when we catch the error.
1935 * throw.c (handler_message): If we are handling an error with a
1936 message, then put together the proper arguments and call
1937 scm_display_error, instead of scm_display_error_message. That
1938 displays source location, if it can find it.
1939
1940 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
1941
1942 * gc.c (scm_unprotect_object): Change this so that calls to
1943 scm_protect_object and scm_unprotect_object nest properly.
1944 (scm_protect_object): Doc fixes.
1945
1946 * strings.c (scm_string_set_x): Require the argument to be a
1947 writable string, not a substring or a symbol.
1948 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
1949 (Thanks to John Redford and Charbel Jacquin.)
1950
1951 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
1952
1953 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
1954
1955 * eval.c (safe_setjmp): Remove this misunderstanding.
1956 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
1957 ordinary setjmp.
1958
1959 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
1960
1961 * libguile.h: Mark these as C declarations, for compilation by C++
1962 compilers.
1963
1964 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
1965 __cplusplus clause. I seriously doubt this ever worked the way
1966 the author seems to have intended.
1967
1968 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
1969
1970 Utterly needless cleanups to hopelessly messy code.
1971 * ports.c: Doc fixes.
1972 (scm_fflush): Moved to ...
1973 * genio.c (scm_fflush): ... here, amongst all the other port
1974 method invocation functions.
1975 * genio.h, ports.h: The prototype moves too.
1976
1977 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
1978
1979 * backtrace.c (display_error_body): The current frame does not
1980 always have a parent frame; consider a function called directly
1981 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
1982 Stachowiak.)
1983
1984 * alloca.c (alloca): Undo yesterday's changes, and simply call
1985 malloc directly for storage, and abort if we don't get what we
1986 want. The situation is much simpler --- just call malloc. Emacs
1987 has bizarre/evil requirements (signal handlers might malloc unless
1988 you set this global flag, so you have to set the flag around all
1989 calls to malloc) which we are certainly not going to conform to,
1990 so we can do the simple and obvious thing.
1991
1992 * coop.c (coop_condition_variable_wait): Make this function
1993 static. It's only useful internally --- you should never just
1994 wait on a condition variable.
1995 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
1996
1997 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
1998
1999 * unif.c (scm_array_set_x): Accept any kind of number as an
2000 element for a uniform vector of doubles. This is more consistent
2001 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2002
2003 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2004 works; I can't conveniently test it myself. (Thanks to Dvid
2005 Tillman for the bug report.)
2006
2007 * init.c: Doc fixes.
2008
2009 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2010 from here, not from scm_compile_shell_switches (which is a pretty
2011 dumb place to do it).
2012 (scm_load_startup_files): New function.
2013 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2014 * script.c (scm_compile_shell_switches): Don't load the startup
2015 files here.
2016 (scm_ice_9_already_loaded): Variable moved.
2017 * init.c (scm_load_startup_files): Prototype for new function.
2018 * gh_init.c (gh_enter): Doc fix.
2019
2020 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2021
2022 Some anti-warning changes from Greg Harvey.
2023 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2024 warnings when it doesn't understand our NORETURN declarations in
2025 error.h.
2026 * posix.c (scm_mknod): Similar.
2027
2028 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2029
2030 * posix.c (scm_getpwuid): If we can't find an entry, return our
2031 own message, instead of using scm_syserror --- the getpwMUMBLE
2032 functions don't set `errno' to anything interesting.
2033
2034 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2035
2036 Get rid of warnings from the cooperative threading system.
2037 * threads.h (scm_single_thread_p, scm_yield,
2038 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2039 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2040 scm_wait_condition_variable, scm_signal_condition_variable): Add
2041 prototypes for these Scheme-visible functions.
2042 * coop-defs.h (coop_next_runnable_thread,
2043 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2044 Prototypes for these here, even though they're from iselect.c.
2045 (coop_condition_variable_wait, coop_join): Add prototypes.
2046 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2047 scm_threads_free_condvar): Make these smob functions static.
2048 * coop-threads.h (coop_init): Give this a real prototype.
2049 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2050 (coop_next_runnable_thread): No need to provide prototype; it's in
2051 coop-defs.h.
2052
2053 * scmconfig.h.in: .detarenegeR
2054
2055 * iselect.c, threads.c: Doc fixes.
2056
2057 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2058
2059 * Makefile.in: Regenerated with a patched automake, to get
2060 dependency generation right when using EGCS.
2061
2062 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2063 warning. (Thanks to Robert Pluim.)
2064
2065 * inet_aton.c (inet_aton): Reassure the compiler that the
2066 arguments to the <ctype.h> macros are all unsigned characters, not
2067 signed characters.
2068
2069 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2070
2071 Getting rid of more warnings...
2072 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2073 today's change to ../configure.in.
2074 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2075 * scmconfig.h.in: Regenertaded.de.,.__
2076 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2077 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2078 time zone name.
2079
2080 * readline.c: Doc fix.
2081 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2082 * readline.h (scm_filename_completion_function): Add prototype.
2083 (scm_init_readline): Make this into a prototype.
2084
2085 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2086 declare this, instead of calling scm_make_subr manually.
2087
2088 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2089
2090 * readline.h (scm_init_readline): Add prototype for this.
2091 (scm_init_readline): Make this a real prototype.
2092
2093 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2094
2095 Warning fixes from Maciej Stachowiak:
2096 * backtrace.h (scm_display_application, scm_backtrace): Add
2097 prototypes.
2098 * debug.c (scm_m_start_stack): Make this function static.
2099 * fluids.h (scm_fluid_p): Add prototype.
2100 * procprop.c (scm_i_procedure_arity): Make this function static.
2101 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2102 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2103 * root.h (scm_dynamic_root): Add external prototype.
2104 * scmsigs.h (scm_usleep): Add external prototype.
2105 * script.h (scm_init_script): Use prototype, not K&R decl.
2106 * stacks.h (scm_stack_id): Add external prototype.
2107 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2108
2109 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2110
2111 * gh.h: took out the definitions of vset and vref, since they are
2112 replaced by the proper vector routines that correspond to the R4RS
2113 procedures.
2114
2115 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2116
2117 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2118 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2119 third argument, a C expression that should result in a SCM value,
2120 which is used to initialize the variable. Reimplemented
2121 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2122 Stachowiak.)
2123
2124 * version.h (scm_libguile_config_stamp): Add prototype.
2125 (From Maciej Stachowiak.)
2126
2127 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2128
2129 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2130 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2131
2132 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2133
2134 * print.c (scm_iprin1): Rather than having one i, and using it in
2135 several places, declare a fresh i local to each block where it is
2136 used, and give it a signedness appropriate to its use in each case.
2137 (scm_iprlist): Same.
2138
2139 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2140 comparison warnings.
2141
2142 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2143 signed/unsigned clashes.
2144
2145 * posix.h (scm_tmpnam): Added prototype.
2146
2147 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2148 scm_make_subclass_object): Add external prototypes.
2149
2150 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2151 comparison is okay here.
2152
2153 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2154
2155 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2156 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2157
2158 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2159 signed/unsigned.
2160
2161 * load.c (swap_port): Make this function static.
2162
2163 * load.c (scm_search_path): Make max_path_len and max_ext_len
2164 unsigned, since they're compared against string sizes.
2165
2166 * load.c (init_build_info): Make i unsigned.
2167
2168 * ioext.h (scm_read_line): Add prototype.
2169
2170 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2171 scm_hash_fn_remove_x): Make hash bucket index local variable k
2172 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2173 accurately as possible.
2174
2175 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2176 comparisons, and range checking to make sure those casts are
2177 harmless.
2178
2179 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2180 signed/unsigned comparisons.
2181
2182 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2183 avoid signed/unsigned comparisons.
2184 * smob.h (scm_numsmob): Change extern declaration to match.
2185
2186 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2187 avoid signed/unsigned comparisons.
2188 * ports.h (scm_numptob): Change extern declaration to match.
2189 (scm_current_load_port, scm_set_port_line_x,
2190 scm_set_port_column_x): New prototypes.
2191
2192 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2193 test code, and it causes warnings.
2194
2195 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2196 gh_uniform_vector_ref): Added prototypes.
2197
2198 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2199 debugging support unconditionally. That's backtrace.c, stack.c,
2200 debug.c, and srcprop.c.
2201 (EXTRA_libguile_la_SOURCES): Omit those from here.
2202 * Makefile.in: Regenerated.
2203
2204 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2205
2206 * options.c (scm_options): Bugfix: Allow empty list of options!
2207
2208 * debug.c, debug.h (scm_single_step): Removed.
2209 (scm_with_traps): New procedure. This procedure could easily be
2210 written in Scheme but needs to be highly optimized.
2211
2212 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2213
2214 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2215 Check SCM_TRAPS_P before trapping.
2216
2217 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2218
2219 Changes to avoid signed/unsigned comparison warnings.
2220 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2221 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2222 so they can have appropriate types for each application. Make i
2223 signed. Use initializers in some spots. I'll probably pay for
2224 all this tweaking.
2225 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2226 (scm_must_realloc): Make nm unsigned.
2227 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2228 (scm_init_storage): Use prototype-style definition, and make the
2229 argument unsigned.
2230 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2231 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2232
2233 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2234 avoid signed/unsigned comparison warnings, and because the return
2235 value of readlink may be -1. Don't bother casting the third
2236 argument to readlink.
2237
2238 * filesys.c (scm_dirname, scm_basename): Move these to their own
2239 page, at the end of the file.
2240 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2241
2242 * eval.h (scm_eval_options_interface): Add external prototype for this.
2243 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2244
2245 * eval.c (scm_lookupcar1): Make this static.
2246
2247 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2248 Make these prototype declarations, not K&R-style.
2249
2250 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2251 unsigned comparison warning.
2252
2253 * appinit.c: File removed. It had a single function in it, empty,
2254 whose reason for existence is explained in no documentation or
2255 comment. I think it's there as a default for some Tcl-style
2256 initialization, but Tcl abandoned that approach a while ago.
2257 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2258 (BUILT_SOURCES): Remove appinit.x.
2259 * Makefile.in: Regenerated.
2260
2261 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2262
2263 * Makefile.in: Regenerated using the last public version of
2264 automake, not the hacked Cygnus version.
2265
2266 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2267
2268 Remove Totoro kludge.
2269 * Makefile.in, scmconfig.h.in: Regenerated.
2270 * init.c, readline.c: Don't check if TOTORO is #defined.
2271
2272 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2273
2274 * Makefile.am: Adjust for new thread configuration system.
2275 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2276 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2277 THREAD_LIBS.
2278 (THREAD_LIBS): Definition deleted; automake will generate such
2279 things automatically.
2280 * Makefile.in: Regenerated.
2281
2282 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2283
2284 Simplify smob and port marking; set the mark bit in the generic
2285 marking code, and make marker routines only responsible for
2286 turning up outgoing pointers.
2287 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2288 before calling the marking function. Don't call the marking
2289 function if it's zero.
2290 * markers.c (scm_mark0): Just return #f. This function isn't
2291 necessary at all now, but it's harmless to call it. We'll leave
2292 it in so other folks' code doesn't croak at link time.
2293 (scm_markcdr): Don't call SCM_SETGC8MARK.
2294 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2295 * dynl.c (mark_dynl_obj): Same.
2296 * root.c (mark_root): Same.
2297 * srcprop.c (marksrcprops): Same.
2298 * unif.c (markra): Same.
2299 * variable.c (scm_markvar): Same.
2300 * ports.c (scm_markstream): Same.
2301 (void_port_ptob): Specify zero for our marking function.
2302 * debug.c (debugobjsmob): Same.
2303 * dynwind.c (guardsmob): Same.
2304 * filesys.c (dir_smob): Same.
2305 * fluids.c (fluid_smob): Same.
2306 * fports.c (scm_fptob, scm_pipob): Same.
2307 * mallocs.c (mallocsmob): Same.
2308 * regex-posix.c (regex_t_smob): Same.
2309 * smob.c (freecell, flob, bigob): Same.
2310 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2311 * throw.c (jbsmob, lazy_catch_funs): Same.
2312
2313 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2314
2315 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2316 scm_copy_tree on code in order not to let memoized code to leak
2317 out. Thus, scm_copy_tree needs to copy vectors as well since
2318 quasiquote can introduce evaluated code also inside vector
2319 constants.
2320
2321 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2322
2323 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2324
2325 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2326 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2327 gh_doubles2dvect.)
2328
2329 * unif.c: Say that ivect and uvect are of type signed and unsigned
2330 long instead of int in commentary so that it correctly describes
2331 the implementation.
2332
2333 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2334
2335 * stime.c: Removed declaration of strptime. (It should be
2336 declared by the system headers. If it turns out that some systems
2337 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2338
2339 * stime.h: Renamed TIMEH --> STIMEH
2340
2341 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2342 to increase portability, don't use structure assignment.
2343 (Thanks to Nicolas Neuss.)
2344
2345 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2346 portability.
2347 (finalize_fd_sets): Added empty statement after last case label.
2348 (Thanks to Nicolas Neuss.)
2349
2350 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2351 Nicolas Neuss.)
2352
2353 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2354
2355 * init.c, readline.c: OK, I won't have these readline.x bug
2356 reports anymore. We've had them since April. The current reason
2357 is a completely unintelligible failure of totoro.red-bean.com to
2358 do the test for rl_getc_function in libreadline correctly. This
2359 kludge overrides the test if we're on totoro so that the snapshot
2360 generation process can work.
2361
2362 * readline.c: Define a strdup replacement if not existent on system.
2363
2364 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2365
2366 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2367 This change makes scm_make_vector R5RS compatible. We cannot keep
2368 the third argument since people want to be able to deduce the form
2369 of the C function call only by looking at R5RS. (At the same time
2370 we have removed some unnecessary complexity!)
2371
2372 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2373 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2374 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2375 argument in call to scm_make_vector.
2376
2377 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2378
2379 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2380 This macro is useful in applications.
2381
2382 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2383
2384 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2385 (scm_parse_path, scm_search_path): New Scheme level procedures.
2386
2387 * load.h (scm_internal_parse_path, scm_parse_path,
2388 scm_search_path): Declared.
2389
2390 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2391
2392 * filesys.c (dirname, basename): New procedures.
2393
2394 * init.c (scm_boot_guile_1): Removed condition around
2395 scm_init_options.
2396
2397 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2398 new data type (guards) for representation of C level guards and
2399 data on the wind chain.
2400 (scm_internal_dynamic_wind): New function.
2401
2402 * dynwind.h: Declare scm_internal_dynamic_wind.
2403
2404 * root.h (scm_root_state): Added scm_cur_loadp.
2405
2406 * root.c (mark_root): Added comment about cur_loadp.
2407
2408 * load.c: #include "dynwind.h";
2409 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2410 scm_cur_loadp.
2411
2412 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2413
2414 * ports.c (current-load-port): New procedure.
2415
2416 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2417
2418 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2419 not a tty, return #f.
2420
2421 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2422 to Julian Satchell and Roland Kaufmann.)
2423
2424 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2425 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2426
2427 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2428
2429 * debug.h, debug.c (scm_start_stack): New function. Implements
2430 the guts of old scm_m_start_stack.
2431
2432 * debug.c (scm_m_start_stack): Use scm_start_stack.
2433
2434 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2435 start_stack and restart_stack. (These have static scope.)
2436
2437 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2438
2439 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2440 readline functions to come in release 2.3. (Thanks to Chet
2441 Ramey.)
2442 (handle_errors): Use the above functions.
2443
2444 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2445
2446 * readline.c: Improvements for readline support: Handle errors
2447 better; Implement before-read-hook.
2448
2449 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2450
2451 * init.c (scm_boot_guile_1), readline.c: Test for
2452 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2453 assure that we have version >= 2.1.)
2454
2455 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2456
2457 * readline.c (scm_readline): Defer interrupts while we're calling
2458 readline.
2459
2460 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2461 away the string to add_history.
2462 (completion_function): Do completion for readline. (Thanks to
2463 Andrew Archibald.)
2464 (scm_filename_completion_function): New procedure: Filename
2465 completer.
2466 (current_input_getc): New function. Use this one instead of
2467 standard getc from readline.
2468
2469 * throw.c, throw.h (scm_handle_by_throw): New function: This
2470 handler throws errors to next handler on the dynwind chain.
2471
2472 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2473
2474 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2475 used.
2476
2477 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2478
2479 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2480 of procedure.
2481 (scm_procedure_properties): Modified to return arity together with
2482 other properties.
2483 (scm_procedure_property): Added the read-only property `arity'.
2484 (scm_set_procedure_property_x): It is an error to set the `arity'
2485 property.
2486
2487 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2488 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2489
2490 * procprop.h (scm_sym_arity): New symbol.
2491
2492 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2493 to set the dispatch procedure of an operator or entity object.
2494
2495 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2496 Made procedure slots read-only.
2497
2498 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2499 scm_tcs_cons_gloc case in zero args switch; Fixed args
2500 construction for operators in scm_tcs_cons_gloc case in two args
2501 switch.
2502
2503 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2504
2505 * fluids.c: Removed use of assert.h (in order to avoid
2506 __eprintf).
2507
2508 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2509
2510 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2511
2512 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2513 change makes the evaluator safer at the cost of evaluation speed.
2514 It handles the case when the user has added a non-immediate
2515 improper end of the application form, e.g., `(+ 0 . x)'.
2516 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2517 minimize the extra cost as much as possible. The new code is
2518 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2519 problem with structs planted directly in the code (e.g. by a
2520 macro). This no longer causes segmentation fault. (Thanks to
2521 Eric Hanchrow.)
2522
2523 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2524 arg `proc' in order to be able to throw errors; New argument
2525 checking code.
2526
2527 * Removed extra #include "debug.h"
2528
2529 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2530
2531 * scmsigs.c: Declare usleep as returning void on some systems.
2532 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2533 Satchell.)
2534
2535 * coop.c (usleep): Return void on some systems.
2536
2537 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2538
2539 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2540
2541 * coop.c: Changed return type of usleep to int.
2542
2543 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2544 isn't found in the OS.
2545
2546 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2547 isn't enabled. (Thought that I had made this change ages ago...)
2548
2549 * iselect.c: Declare bzero if not defined by OS.
2550
2551 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2552
2553 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2554 condition. (Thanks to John Tobey.)
2555
2556 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2557 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2558 A section.
2559
2560 * __scm.h: Start the long-term project of moving to POSIX threads.
2561 Phase 1: Classification of all critical sections.
2562 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2563 for A sections. (See comments in __scm.h for details.)
2564
2565 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2566 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2567
2568 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2569
2570 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2571 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2572 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2573 dependencies on $(srcdir)/Makefile.in
2574 $(top_builddir)/config.status in order to avoid circularity.
2575
2576 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2577 from argc if argc was 0 initially.
2578
2579 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2580 in generation of libpath.h.
2581
2582 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2583
2584 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2585 libguile from 2 to 3.
2586
2587 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2588
2589 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2590
2591 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2592
2593 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2594 scm_set_port_column_x, scm_port_filename,
2595 scm_set_port_filename_x): Removed optional arguments. Added
2596 proper argument checking.
2597
2598 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2599 stack size in machine words.
2600
2601 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2602 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2603 to Ole Myren Röhne.)
2604
2605 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2606
2607 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2608 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2609
2610 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2611 Caradoc-Davies.)
2612
2613 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2614 procedure apply: Copy argument lists before pushing them unto the
2615 environment so that the environment won't get mutated due to
2616 manipulation of procedure arguments. This should perhaps be
2617 regarded as a temporary solution until someone finds a more
2618 efficient one. (Thanks to Maciej Stachowiak.)
2619
2620 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2621
2622 * script.c (scm_compile_shell_switches): Use "guile" as default
2623 zero arg if argc is NULL.
2624
2625 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2626
2627 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2628 is zero. (Thanks to Dirk Herrmann.)
2629
2630 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2631
2632 * ports.c (scm_add_to_port_table): First line is now line 0
2633 (was 1). (Interface changed according to suggestion by Per
2634 Bothner.)
2635
2636 * backtrace.c (display_header): Add 1 to line and column numbers
2637 when presenting them to the user.
2638
2639 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
2640 from debug.c --> eval.c
2641
2642 * eval.h, eval.c (scm_eval_options_interface): New options
2643 interface.
2644 (SCM_EVAL_STACK): New option: Size of newly created stacks,
2645 i.e. stacks for new threads.
2646
2647 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
2648
2649 * eval.c (unsafe_setjmp): Removed with #if 0.
2650
2651 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
2652 warning.
2653
2654 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
2655 to avoid compiler warnings.
2656
2657 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
2658
2659 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
2660
2661 * throw.c (handler_message): Print message on current error port
2662 instead of default error port. (Thanks to Maciej Stachowiak.)
2663
2664 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
2665
2666 * ports.c (scm_add_to_port_table): allocate in units of
2667 struct scm_port_table *, not struct scm_port_table.
2668 * posix.c (scm_close_pipe): remove the port from the port table
2669 and mark as closed.
2670 Thanks to Rob Engle for both fixes.
2671
2672 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2673
2674 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
2675 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
2676
2677 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2678
2679 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
2680
2681 * backtrace.c (display_error_body, display_backtrace_body),
2682 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
2683 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
2684 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
2685 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
2686 functions.
2687
2688 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
2689 don't receive the jmpbuf arg anylonger.
2690 (scm_catch): Don't accept a #f tag.
2691 (scm_throw): Check that key is a symbol.
2692 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
2693
2694 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
2695
2696 * async.c (async_pending): Removed declaration.
2697
2698 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2699
2700 * dynwind.c (scm_wind_chain): New debug function.
2701
2702 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
2703 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
2704 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
2705 extra layer of functions around the body and handler of a thread.
2706 This extra layer makes sure that the handler is called in the
2707 dynamic context of the surround (= empty dynwind list), but under
2708 the *dynamic root* of the body. We can not use the dynamic root
2709 of the surround since that root belongs to another thread => stack
2710 is not handled correctly. It may seem ugly to use this extra
2711 layer, but the extra cost in terms of execution time is really
2712 negligible compared to the total amount of time required to create
2713 a thread, and it would reduce maintainability to duplicate the
2714 crucial and complicated steps performed by cwdr.
2715
2716 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
2717 (SCM_ALLOW_INTS): Added thread switching code before interrupts
2718 get re-enabled. The important effect of this is that interrupts
2719 are blocked during thread switching so that thread data structures
2720 don't risk getting messed up by an unfortunate signal.
2721 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
2722 seems to do more aggressive optimization which actually move
2723 instructions around in these macros in a fatal way. Therefore:
2724 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
2725 just superstitious...)
2726 (SCM_TICK): Maybe do a context switch and take care of asyncs.
2727 This macro should be used instead of SCM_ASYNC_TICK since the
2728 latter doesn't do context switches any more.
2729
2730 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
2731 instead of SCM_ASYNC_TICK.
2732
2733 * coop.c, iselect.c: Since thread switches are now performed with
2734 interrupts masked, we can't use the old mechanism of delivering
2735 signals immediately when they arrive. Signals must instead be
2736 delivered when the asyncs run *after* the end of the critical
2737 section in scm_internal_select. But this also means after context
2738 switch so that the signal will be delivered to a different thread.
2739 To avoid this, I have changed the protocol of
2740 coop_wait_for_runnable_thread and friends so that they are allowed
2741 to return the original thread. So, if a signal arrives during
2742 scm_internal_select, we won't any longer be forced do a context
2743 switch, but can remain in the same thread and deliver the signal
2744 to it.
2745
2746 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
2747 scm_asyncs_pending and made it global.
2748
2749 * iselect.c: Small fixes.
2750
2751 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
2752 coop_condition_variable_init, coop_condition_variable_wait,
2753 coop_condition_variable_signal): Changed return type from `void'
2754 to `int'. This is to adhere closer to the pthreads interface.
2755 This, in turn, is part of an attempt to provide C versions of the
2756 mutex and condition variable primitives which can be part of a
2757 frontend to COOP or pthreads.
2758
2759 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
2760 coop_condition_variable_destroy): New functions.
2761
2762 * coop-threads.c (scm_wait_condition_variable): Use
2763 coop_condition_variable_wait_mutex.
2764
2765 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
2766 Definitions moved to coop-defs.h.
2767
2768 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
2769 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
2770 scm_cond_destroy): New C interface to mutecis and cond vars.
2771
2772 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2773
2774 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
2775
2776 * iselect.c: Now several threads can wait on the same file
2777 descriptor. The behaviour is compatible with OS select: All
2778 threads waiting for the fd return with the same status.
2779
2780 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2781
2782 * coop-threads.c, threads.h (scm_spawn_thread): New function.
2783 Can spawn a thread from application C code.
2784
2785 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2786
2787 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
2788 gh_doubles2scm): New functions.
2789
2790 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
2791
2792 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
2793 commented-out version of gh_eval_str()
2794
2795 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
2796
2797 * socket.c (scm_bind): free soka after use.
2798
2799 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
2800
2801 * stime.c (tzvar): new variable.
2802 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
2803 avoid memory leaks when allocating.
2804
2805 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
2806
2807 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
2808 macro definitions.
2809
2810 * gc.c, tags.h: Doc fixes.
2811
2812 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2813
2814 * eval.c (macro-eval!): Removed. This function was a design bug.
2815 It allowed memoized code to leak out to the scheme level. Most
2816 things that you could do with `macro-eval!' can be done with
2817 `local-eval'.
2818
2819 1997-12-20 Tim Pierce <twp@skepsis.com>
2820
2821 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
2822 scm_fgets now depends on ftell(3) to know how many bytes were
2823 read. Sigh.
2824
2825 1997-12-15 Tim Pierce <twp@skepsis.com>
2826
2827 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
2828 dealing with strings.
2829
2830 1997-12-13 Tim Pierce <twp@skepsis.com>
2831
2832 Make %read-line more suitable for implementing read-line efficiently.
2833 * ioext.c (scm_read_line): Strip the terminating newline from a
2834 string, and return a cons of the string and its terminator.
2835
2836 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
2837 of the string that is read is stored in this memory location.
2838 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
2839 * genio.c, genio.h (scm_do_read_line): Update caller.
2840 * ports.h (scm_ptobfuns): Update typedef.
2841 * fports.c (scm_fptob, scm_pipob): Update struct.
2842
2843 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2844
2845 * filesys.c (set_element): Return file descriptor.
2846 (fill_select_type): Return the highest file descriptor.
2847 (scm_select): Tell select about the highest file descriptor. On
2848 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
2849 Therefore the extra overhead for calculating the maximum fd seems
2850 to be more than compensated. Is this correct? In any case,
2851 scm_internal_select will be much faster with this info.
2852 (scm_select, fill_select_type, set_element): Don't accept any kind
2853 of object in the file descriptor list or vector.
2854
2855 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2856
2857 * iselect.c (finalize_fd_sets): Bugfix.
2858
2859 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2860
2861 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
2862 when using scm_internal_select (since we might switch to another
2863 thread).
2864
2865 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2866
2867 * simpos.c (scm_system): always define: use sysmissing if not
2868 available. Check for HAVE_SYSTEM instead of _Windows (does
2869 Windows lack system or does it have an unusable one?).
2870 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
2871 Let the argument be optional: if not supplied, call system(NULL).
2872
2873 * ports.c (scm_close_port): relax the type check from OPPORTP to
2874 PORTP; closing a closed port is allowed.
2875
2876 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
2877
2878 * fports.c (scm_fgets): Return if the last char in a chunk is
2879 newline. When fgets returns a string whose length is `size-1', it
2880 is ambiguous whether a whole line was retrieved, so we must check
2881 explicitly whether a line terminator is present.
2882
2883 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2884
2885 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
2886 before taking the CDR. (Thanks to Harald Meland.)
2887
2888 * filesys.c (scm_stat): Slightly optimized.
2889
2890 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
2891
2892 * ports.c (scm_close_port): Make sure the port is open before
2893 trying to close it.
2894
2895 * guile-snarf.in: Pass args through to gcc in a way that preserves
2896 whitespace boundaries. (Thanks to Greg Badros.)
2897
2898 1997-12-02 Tim Pierce <twp@skepsis.com>
2899
2900 * stacks.c (scm_frame_procedure): Reverse the logic in the return
2901 statement. (Thanks to Doug Evans for pointing this out.)
2902
2903 1997-12-01 Tim Pierce <twp@skepsis.com>
2904
2905 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
2906
2907 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
2908
2909 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
2910 errno macro expansion of this field name. (errno is a C
2911 preprocessor macro on some systems.)
2912
2913 1997-11-29 Tim Pierce <twp@skepsis.com>
2914
2915 * iselect.c: Doc fix.
2916
2917 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
2918
2919 * init.c (scm_start_stack): Removed initialization of
2920 scm_the_last_stack_var.
2921
2922 * backtrace.h: Declare scm_the_last_stack_var.
2923
2924 * backtrace.c: Define scm_the_last_stack_var.
2925
2926 * root.c (mark_root): Don't mark the_last_stack_var.
2927
2928 * root.h (scm_root_state): Removed the_last_stack_var.
2929
2930 * throw.c: Added #include "fluids.h"
2931 (ss_handler): `the-last-stack' is now a fluid.
2932
2933 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
2934 --> the_last_stack_fluid.
2935
2936 * backtrace.c: Added #include "fluids.h"
2937 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
2938 (scm_backtrace): `the-last-stack' is now a fluid.
2939
2940 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
2941 after scm_init_fluids.
2942
2943 1997-11-28 Tim Pierce <twp@skepsis.com>
2944
2945 * iselect.c: #ifdef USE_THREADS around thread-related includes.
2946
2947 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
2948 DLSYM_ADDS_USCORE to decide whether to add an underscore.
2949
2950 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2951
2952 * iselect.c (coop_next_runnable_thread,
2953 coop_wait_for_runnable_thread): Disable interrupts so that no
2954 async is executed before a potential error_revive.
2955 (scm_internal_select): Disable interrupts during the parts of the
2956 code which manipulate the sleep queue and the file descriptors.
2957
2958 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2959
2960 * Makefile.am: Added iselect.c and iselect.h.
2961
2962 * coop.c (coop_qinit): Initialize fields used by
2963 scm_internal_select.
2964 (coop_qget, coop_qget, coop_tmp_queue): Made global.
2965 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
2966 replacement in iselect.c.
2967 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
2968 coop_join): If GUILE_ISELECT enabled, use
2969 coop_wait_for_runnable_thread instead of
2970 coop_next_runnable_thread.
2971 (usleep, sleep): New replacements for system functions if
2972 GUILE_ISELECT is enabled.
2973
2974 * coop-threads.h: Declare coop_wait_for_runnable_thread.
2975
2976 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
2977
2978 * filesys.c: Added #include "iselect.h". Moved FD-macros to
2979 iselect.h. Implement Scheme level `select' using
2980 scm_internal_select. (See NEWS.)
2981
2982 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
2983
2984 * init.c: Call scm_init_iselect.
2985
2986 * iselect.h, iselect.c: New files. Implements
2987 scm_internal_select. (See NEWS.)
2988
2989 1997-11-27 Tim Pierce <twp@skepsis.com>
2990
2991 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
2992 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
2993 and scm_must_free, since ultimately the string returned will be copied
2994 by scm_makfrom0str anyway. Also, read any characters that may have
2995 been pushed onto the port with scm_ungetc.
2996 * ports.c (scm_generic_fgets): Same as for scm_fgets.
2997 * ioext.c (scm_read_line): Free string after Guilifying it.
2998 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
2999
3000 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3001
3002 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3003
3004 * gh.h: Safely wrap prototypes for c++ usage.
3005
3006 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3007
3008 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3009 gh_repl (argc, argv).
3010
3011 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3012
3013 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3014 and to invoke scm_shell().
3015 (gh_launch_pad): took out the loading of boot-9.scm from here,
3016 since it is probably best to let the user control that. In fact,
3017 gh_repl() now invokes scm_shell() which does that.
3018
3019 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3020
3021 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3022 invocation.
3023
3024 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3025
3026 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3027 yesterday's underscore patch. (Thanks to Marius Vollmer for
3028 spotting this.)
3029
3030 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3031
3032 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3033 DLSYM_ADDS_USCORE is not defined.
3034
3035 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3036
3037 * gh_data.c (gh_uniform_vector_length):
3038 (gh_uniform_vector_ref): started implementing the uniform types in
3039 the gh_ interface.
3040
3041 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3042
3043 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3044 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3045
3046 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3047
3048 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3049 configure.in was changed).
3050
3051 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3052
3053 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3054 * Makefile.in: Regenerated.
3055
3056 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3057
3058 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3059 OPORT is an `open' port, not an output port.
3060
3061 * filesys.c (scm_close, set_element, get_element, scm_chown,
3062 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3063 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3064 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3065 scm_close_port, scm_port_line, scm_set_port_line_x,
3066 scm_port_column, scm_set_port_column_x, scm_port_filename,
3067 scm_set_port_filename_x, scm_port_mode,
3068 scm_close_all_ports_except, scm_set_current_output_port,
3069 scm_set_current_error_port): Likewise
3070 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3071 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3072 Likewise
3073 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3074 * backtrace.c (display_backtrace_body): Likewise
3075 * fports (scm_setvbuf): Likewise
3076 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3077 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3078 scm_getpeername, scm_send, scm_sendto): Likewise
3079 * unif.c (scm_uniform_array_write): Likewise
3080
3081 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3082
3083 Minor problems with substring-related tag changes.
3084 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3085 exactly what we want to leave in to detect substrings.
3086 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3087 * tags.h: Fix diagrams and comments describing the S tag bit;
3088 remove vestigial remarks about the D tag bit.
3089 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3090 * strings.c: Formatting tweaks.
3091
3092 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3093 variable first; then SCHEME_LOAD_PATH, with a warning message.
3094 (scm_parse_path): New function.
3095 * script.c: Doc fixes.
3096
3097 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3098

3100 * readline.c, readline.h: New files.
3101 * init.c: #include "readline.h".
3102 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3103 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3104 * Makefile.in: Regenerated.
3105 * scmconfig.h.in: Regenerated, after change to ../configure.
3106

3108
3109 * gh.h: gh_vector_set -> gh_vector_set_x
3110
3111 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3112
3113 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3114 with the ! -> _x mapping when going from Scheme to C.
3115
3116 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3117
3118 * gh.h (gh_reverse):
3119 (gh_list_tail):
3120 (gh_list_ref):
3121 (gh_memq):
3122 (gh_memv):

3124 (gh_assq):
3125 (gh_assv):
3126 (gh_assoc): added these gh_ functions implemented as macros.
3127
3128 * gh_predicates.c (gh_null_p):
3129 (gh_string_equal_p): added these two missing predicates.
3130
3131 * gh_list.c (gh_append):
3132 (gh_append2):
3133 (gh_append3):
3134 (gh_append4):
3135 (gh_set_car_x):
3136 (gh_set_cdr_x): added these routines as I go through and try to
3137 complete the picture R4RS functions that should be mirrored in the
3138 gh_ interface.
3139
3140 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3141
3142 * tags.h (scm_tc7_substring): Changed the comment and code to
3143 conform with the changes below. Folks! We have suddenly two new
3144 free tc7 codes!!! Jummy, jummy!
3145
3146 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3147
3148 * Makefile.in: Rebuilt.

3169 (scm_tc7_mb_string): Removed.
3170 (scm_tc7_mb_substring): Removed.

3175 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3176 multi-byte flag.
3177 Don't include "mbstrings.h".
3178 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3179 (SCM_SYMBOL_SLOTS): Define as 4.
3180 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
3181 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3182 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3183 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3184 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
3185 ("gen"-less) I/O function names.
3186 * ports.c (scm_add_to_port_table): Don't set port's
3187 representation.
3188 * ports.h (scm_port_representation_type): Removed.
3189 (scm_string_representation_type): Removed.
3190 (struct scm_port_table ): Removed representation field.
3191 (SCM_PORT_REPRESENTATION): Removed.
3192 (SCM_SET_PORT_REPRESENTATION): Removed.
3193 * genio.h: Use new function names.
3194 * genio.c: Don't include "extchrs.h".
3195 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
3196 Removed.
3197 (scm_putc, scm_puts, scm_lfwrite): No longer static.
3198 (scm_getc): No longer static; handle line and column changes.

3204 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3205
3206 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3207
3208 * gh_test_c.c (c_vector_test): some improvements on the vector
3209 routines test.
3210
3211 * gh.h (gh_vector): this used to exist but do the wrong thing.
3212 Now it (almost) does the right thing, though it takes a list
3213 instead of the individual arguments. I need to see how it could
3214 be done right.
3215 (gh_list_to_vector): added this function as a macro. Corresponds
3216 to Scheme's (list->vector ...).
3217 (gh_vector_to_list): added this function as a macro. Corresponds
3218 to Scheme's (vector->list ...).
3219
3220 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3221 gh_vector_ref, so that it resembles the Scheme routines more.
3222 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3223 resembles the Scheme routines more.
3224 (gh_make_vector): this used to be (stupidly) called gh_vector().
3225 This is the right name, since it does the same thing as the Scheme
3226 (make-vector ...) procedure.
3227
3228 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3229
3230 * ports.h: #include "libguile/print.h"
3231
3232 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3233 Some indentation fixes.
3234
3235 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3236 longer a user field; New field: class_flags.
3237
3238 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3239
3240 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3241
3242 * gh_data.c (gh_bool2scm): new function which replaces
3243 gh_int2scmb(), which is now tagged as obsolete.
3244
3245 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3246
3247 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3248 macros should by convention not test for NIMPness.)
3249 (SCM_COERCE_OPORT): Adjust indentation.
3250
3251 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3252 SCM_NIMP test before SCM_PRINT_STATE_P.
3253
3254 * struct.c, struct.h, gc.c: Renamed:
3255 scm_struct_i_layout --> scm_vtable_index_layout
3256 scm_struct_i_vcell --> scm_vtable_index_vcell
3257 scm_struct_i_vtable --> scm_vtable_index_vtable
3258 scm_struct_i_printer --> scm_vtable_index_printer
3259 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3260
3261 * struct.c (scm_print_struct): Use new printer slot; Default
3262 printing: Also output hex code of vtable so that type identity
3263 will be indicated as well.
3264 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3265 Removed struct_printer_var; Removed struct-vtable-offset;
3266 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3267 vtable-offset-user): New constants.
3268
3269 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3270 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3271 If this slot contains a procedure, use that to print structures of
3272 the type represented by this vtable.
3273
3274 * print.c (scm_iprin1): Don't print arguments of macro
3275 transformers. (They are always: exp env.); Bugfix: Unmemoize
3276 transformer source with correct environment.
3277
3278 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3279
3280 Streamlining of call-with-dynamic-root:
3281
3282 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3283 there is now only one catch.
3284 (cwdr_outer_body): Removed.
3285 (cwdr_handler): New function.
3286 (scm_internal_cwdr): New function to perform the function of cwdr
3287 but take args that are more useful to C code. Also, the handler
3288 is now invoked *outside* of the new dynamic root, like the docs
3289 say. We no longer have to catch absolutely all errors, the caller
3290 is responsible for using a handler that does not throw, if he
3291 wants that.
3292 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3293 * root.h (scm_internal_cwdr): New prototype.
3294
3295 Even more but risky streamlining:
3296
3297 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3298 allocation of the jumpbuf of a root continuation. The changes
3299 below are controlled by it. They are now deactivated.
3300 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3301 the JMPBUF of the scm_rootcont to NULL before returning.
3302
3303 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3304 when they are non-NULL.
3305 (scm_gc_mark): Likewise, mark only when non-NULL.
3306
3307 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3308 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3309
3310 * gc.c (scm_done_malloc): New function.
3311 gc.h (scm_done_malloc): New prototype.
3312
3313 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3314 (struct scm_print_state) [revealed]: New field.
3315 (scm_print_state_vtable): Make visible to the outside world for
3316 type checking purposes.
3317 (scm_valid_oport_value_p): New prototype.
3318
3319 * print.c (scm_valid_oport_value_p): New function to check whether
3320 a certain value is acceptable as a port argument.
3321 (scm_print_state_vtable): New variable.
3322 (scm_free_print_state): Set `revealed' field to false.
3323 (scm_iprin1): Call user supplied closure printer with
3324 scm_printer_apply. Print in the traditional way when there isn't
3325 one or when it returns #f.
3326 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3327 Accept a port/print-state pair in addition to just a port.
3328 (scm_prin1): Don't return the print_state to the pool when it has
3329 been `revealed'.
3330 (scm_printer_apply): Set `revealed' field of print_state to true.
3331 (scm_init_print): Set scm_print_state_vtable.
3332 (print_state_fluid, print_state_fluid_num): Removed.
3333
3334 * throw.h (scm_handle_by_proc_catching_all): New prototype
3335 throw.c (scm_handle_by_proc_catching_all): New function
3336
3337 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3338
3339 * Makefile.in: Regenerated with automake 1.2c.
3340
3341 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3342
3343 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3344 was looping endlessly.
3345
3346 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3347
3348 * strports.c (scm_eval_string): Don't close the port.
3349
3350 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3351 former returns a nice normal integer. (Thanks to Daniel
3352 Risacher.)
3353
3354 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3355
3356 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3357 makefile variable as a build parameter called LIBS. The
3358 build-guile program will use this, for the time being.
3359 * Makefile.in: Regenerated.
3360
3361 Thanks to Shiro Kawai:
3362 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3363 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3364 an SCM.
3365
3366 * Makefile.in: Regenerated with automake 1.2a.
3367
3368 * script.c (scm_compile_shell_switches): If we hit the -c or --
3369 arguments, don't set the car of (command-line) to scm_usage_name,
3370 the prettified name of the guile executable; give it the full
3371 path, the way shells usually handle $0.
3372
3373 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3374
3375 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3376 Scheme-level name `array-map' and renamed `serial-array-map' to
3377 `serial-array-map!'.
3378
3379 * backtrace.c: Introduced exception handlers which now enclose
3380 `display-error' and `display-backtrace' so that error reporting
3381 won't get into infinite loops if an error occurs during displaying
3382 of the error. This can very easily happen with user supplied
3383 print call-back routines.
3384
3385 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3386
3387 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3388 the names `serial-array-map' and `array-map' should be removed.)
3389
3390 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3391
3392 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3393 Added #include "objects.h"
3394
3395 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3396 Add #include "feature.h".
3397
3398 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3399 (modinclude_HEADERS): Added objects.h.
3400
3401 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3402 This test is needed at many places in the code and should be
3403 abstracted. (Motivated by the need of this test in libguiletk.)
3404
3405 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3406 (scm_eval_string), load.c (scm_primitive_load,
3407 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3408 Use SCM_EOF_OBJECT_P.
3409
3410 * eval.c (scm_init_eval): Add feature `delay'.
3411
3412 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3413
3414 * scmhob.h: Removed.
3415
3416 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3417
3418 * list.h (SCM_LISTn): New macros. Make list creation in C code
3419 prettier. The idea comes from STk.
3420
3421 * sequences.h, sequences.c, append.h, append.c: Removed. These
3422 files implemented non-R4RS operations which would encourage
3423 non-portable programming style and less easy-to-read code.
3424
3425 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3426 Removed.
3427
3428 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3429 sequences.h, #include append.h.
3430
3431 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3432 scm_init_sequences.
3433
3434 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3435
3436 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3437
3438 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3439
3440 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3441
3442 * eval.c: Added #include "objects.h"
3443
3444 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3445 and entities.
3446
3447 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3448 adjacent smob numbers.
3449
3450 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3451
3452 * procprop.h: Added declaration of scm_i_inner_name.
3453
3454 * gsubr.c: New global symbol scm_i_inner_name.
3455
3456 * debug.c (scm_procedure_name): Try procedure property
3457 `inner-name' if `name' fails.
3458
3459 * print.c (scm_iprin1): Use scm_macro_name.
3460
3461 * eval.c (scm_m_define): Give names to macros as well; Only the
3462 first top-level definition gives a procedure/macro a name.
3463 Otherwise confusing names can turn up in backtraces.
3464 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3465 `name'; Give names to macros as well.
3466
3467 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3468 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3469 scm_closure_p.
3470
3471 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3472
3473 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3474 procedures;
3475 (prinmacro): Removed. The code has been moved/merged into print.c
3476 in order to decrease code redundancy. We want macros to print in
3477 a way equivalent to procedures, and it would be silly to duplicate
3478 the required code. (We don't want to maintain two places.)
3479 (macrosmob): Print field is now a NULL pointer.
3480
3481 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3482 scm_macro_transformer): New prototypes.
3483 (scm_tc16_macro): Declared.
3484
3485 * print.c (scm_iprin1): Added code for printing of macros. Macros
3486 are now printed in a way equivalent to procedures.
3487
3488 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3489
3490 * procs.h (scm_closure_p): Added declaration.
3491
3492 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3493
3494 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3495 Shouldn't pass "heap" as the subr name.
3496
3497 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3498
3499 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3500 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3501 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3502 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3503 SCM_BOOL_T. Any non-false value is true.
3504
3505 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3506
3507 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3508 scm_gensym): Added prototypes.
3509
3510 * symbols.c (scm_gensym): New function. This will speed up
3511 certain types of applications (such as macro systems) which
3512 generate lots of symbols.
3513
3514 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3515

3519
3520 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3521 specifier, since (2) or (2 . 3) would cause SEGV.
3522 (scm_transpose_array): more argument checking fixes.
3523
3524 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>

3528 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3529
3530 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3531
3532 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3533
3534 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3535
3536 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3537
3538 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3539 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3540 library.)
3541
3542 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3543 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),

3549
3550 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3551

3556
3557 * list.c (scm_list_append_x): Allow non-pair as last argument.
3558 This is consistent with the R4RS append and is probably the
3559 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3560
3561 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3562
3563 * stime.h: prototype for scm_times.
3564 * stime.c (scm_times): new procedure.
3565 * ioext.c (scm_fseek): if the first argument is a file descriptor
3566 call lseek.

3575 Add DEFER/ALLOW INTS to a few other procedures.
3576 (scm_fsync): new procedure.
3577 (scm_open_fdes): new procedure.
3578 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3579 now be used.

3581 third argument is now optional.
3582
3583 * posix.c (scm_execl, scm_execlp): make the filename argument
3584 compulsory, since omitting it causes SEGV.
3585 (scm_sync): return unspecified instead of #f.
3586 (scm_execle): new procedure.
3587 (environ_list_to_c): new procedure.
3588 (scm_environ): use environ_list_to_c. disable interrupts.

3590 improve error checking.
3591
3592 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3593
3594 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3595 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3596 argument to SCM_ASSERT. Furthermore, the name of the function
3597 should be passed as first argument when signalling
3598 SCM_WNA. (Thanks to Thomas Morgan)
3599
3600 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3601 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3602 dispatches on the number of actual args has a default case
3603 reporting an internal error. This is a vestige from a version
3604 that mallocated a SCM vector to hold the arguments. In the
3605 current version this check is too late: if it ever happens we will
3606 have already overstepped the bounds of the array.
3607
3608 Also, the patch [...] adds a check for too many actual arguments."
3609
3610 mdj: Removed check for "internal programming error".
3611
3612 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3613
3614 * gh_io.c (gh_write): New function.
3615
3616 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3617 throw.c (scm_internal_stack_catch): New sibling to the other catch
3618 functions. Code moved from gh_eval.c.

3624
3625 * ioext.h: fix up prototypes.
3626 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3627 Scheme name is now dup->fdes.
3628 (scm_dup_to_fdes): make the second argument optional and
3629 fold in the functionality of scm_primitive_dup.
3630 (scm_primitive_dup): deleted.
3631
3632 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>

3634 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
3635 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or

3647
3648 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
3649
3650 * print.c (scm_iprin1): Enter printed structures into the print
3651 state as nested data while they are printed.
3652 (print_state_fluid, print_state_fluid_num): New variables.
3653 (scm_init_print): Initialize them.
3654 (scm_iprin): If print_state_fluid carries a print_state, use that
3655 instead of creating a new one.
3656 (scm_printer_apply, apply_stub, struct apply_data): New
3657 definitions to help with calling printer functions written in
3658 Scheme.
3659 * print.h (scm_printer_apply): New prototype.
3660

3669
3670 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
3671
3672 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
3673 SCM_ASSERT: arg comes before pos.
3674
3675 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3676
3677 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

3697
3698 * ioext.c (scm_primitive_dup2): return the new file descriptor
3699 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
3700 is convenient.
3701 (scm_fdopen): bug fix: don't try to make port unbuffered until its
3702 stream has been set.
3703 (scm_duplicate_port): deleted, there's now an implementation in
3704 boot-9.scm.
3705 (scm_primitive_dup2): do nothing if newfd == oldfd.
3706
3707 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

3728
3729 * filesys.h: scm_close prototype.
3730 * filesys.c (scm_close): new procedure, can close file descriptors
3731 and ports (scsh compatible).
3732
3733 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
3734 optional argument.
3735
3736 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
3737
3738 * fluids.c, fluid.h: New files.

3740 (modinclude_HEADERS): Added "fluids.h"
3741

3749 (scm_make_root): Call scm_copy_fluids to make fluid bindings
3750 unique for the new root when it has a parent.
3751
3752 * smob.h: Include "libguile/print.h" to make scm_print_state
3753 visible.
3754
3755 * dynl.c (free_dynl_obj): New function to free the dynamic object
3756 data. (dynl_smob): Use it.
3757 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
3758 the dynamic object data below the linking of the object to avoid
3759 memory leak when the linking code throws an error. Now the code
3760 leaks a whole dynamically linked library when must_malloc throws,
3761 but that should be much less likely.
3762
3763 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
3764
3765 Changes to compile under gnu-win32, from Marcus Daniels:

3767 (scm_localtime): Change SCM_EOF to SCM_EOL.
3768 (scm_mktime): Likewise.
3769 * socket.c: Don't include sys/un.h unless autoconf tells
3770 us Unix domain sockets are available.
3771 (scm_fill_sockaddr): Ignore Unix domain code.
3772 (scm_addr_vector): Likewise.
3773 (scm_init_addr_buffer): Likewise.

3782 (scm_setegid): For setegid.
3783 * net_db.c (scm_inet_netof): Don't include unless support

3800
3801 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
3802 arguments for formatting the error message, not SCM_BOOL_F. I
3803 think this is left over from the (eq? '() #f) days.
3804
3805 * read.c (recsexpr): Give this a dummy definition if
3806 DEBUG_EXTENSIONS isn't #defined.
3807
3808 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

3819
3820 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
3821 alloca.lo will be included in @LIBLOBJS@. Something better than
3822 this should be possible.
3823 * Makefile.in: Regenerated.
3824
3825 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3826
3827 * simpos.h: prototype for scm_primitive_exit.
3828 * simpos.c (scm_primitive_exit): new procedure, terminates the
3829 process without unwinding the stack.
3830
3831 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
3832
3833 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
3834 argument and logior its components together, so the user doesn't
3835 have to do this explicitly. Also, if regexp/basic is supplied, then
3836 turn off REG_EXTENDED.
3837 (scm_init_regex_posix): New regexp/basic symbol.
3838 (REG_BASIC): #define this if it is not already present.

3859 regexp/nosub flag.
3860
3861 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
3862 FLAGS arguments.
3863 (scm_init_regex_posix): Define constants for the REG_mumble flags;

3867

3880
3881 * root.c: Establish a reliable catch-all handler for the new root.
3882 After all the Scheme handler function might signal an error too,
3883 and we don't want to lose that.
3884 (cwdr_inner_body): Renamed from cwdr_body.
3885 (cwdr_outer_body): New function, to establish the user's handler,
3886 and pass control to cwdr_inner_body.
3887 (cwdr): Establish the reliable catch-all handler here, and pass
3888 control to cwdr_outer_body.
3889 (struct cwdr_body_data): New field, handler, to allow cwdr to pass

3897 across this. Only works on GCC. Otherwise, we hope for the best.
3898 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
3899 the feeling that real thread systems will not need this...
3900
3901 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
3902
3903 Try to detect when people are using one version of libguile and a
3904 different version of ice-9. People have been skewing things and
3905 sending in bug reports.
3906 * Makefile.am (versiondat.h): New file to generate.
3907 * version.c: #include "versiondat.h", to get version info.
3908 (scm_libguile_config_stamp): New function.
3909 * script.c: #include "version.h".
3910 (scm_compile_switches): Call scm_version to get version number.
3911 * scmconfig.h.in, Makefile.in: Regenerated.
3912 * Makefile.in: Regenerated.
3913
3914 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
3915 primitive definitions under their Scheme names.
3916
3917 * Makefile.am (libguile_la_LDFLAGS): Update library version to
3918 1:2. Helps avoid confusion between installed and uninstalled libs.
3919
3920 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
3921 ../configure.in.)
3922
3923 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
3924 backslash from definition; this should be used like: GDB_INTERFACE;
3925
3926 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3927
3928 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
3929 new port unbuffered until its stream has been set.
3930
3931 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
3932
3933 * ports.h: new prototype.
3934 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
3935
3936 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
3937
3938 Make things compile neatly under Sun's C compiler.
3939 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
3940 * extchrs.c (xmbtowc): Make the second arg a normal char, not
3941 unsigned, because that's what the ANSI function takes.
3942 * extchrs.h (xmbtowc): Corresponding change to prototype.
3943 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
3944 uchars here.
3945 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
3946 argument plain char *.
3947 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
3948 char.
3949 * tag.c (scm_tag): Remove unreachable statement.
3950 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
3951 top of the word, it should be unsigned.
3952
3953 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
3954 is defined, to avoid warnings; it's only used in the
3955 conflict-checking code. Which might go away anyway.
3956 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
3957 conditionals; put the label definition in an #if too, to stifle
3958 warnings.
3959
3960 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
3961 ChangeLog-threads in the distribution.
3962 * Makefile.in: Regenerated.
3963
3964 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3965
3966 * guile-snarf.in: Changed regexp to support CPPs that insert
3967 whitespace between lexical tokens (which munges the `%%%' snarf
3968 cookie).
3969
3970 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3971
3972 * load.c (scm_init_load_path): Append $(datadir)/guile to
3973 %load-path, so modules do not have to be installed in Guile's
3974 current version directory.
3975
3976 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
3977
3978 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
3979 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
3980 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
3981 call the sysdep functions with deferred ints.
3982 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
3983 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
3984 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
3985 error.
3986
3987 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
3988 SCM_UNSPECIFIED.
3989
3990 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
3991
3992 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
3993
3994 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
3995
3996 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
3997 ../configure.in.
3998
3999 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4000
4001 * eval.c (scm_lookupcar1): New procedure to cope with a race
4002 condition during lookup (when using threads).
4003 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4004 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4005 place.
4006
4007 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4008
4009 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4010 supplied. (Change from Tim Pierce.)
4011
4012 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4013
4014 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4015 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4016 default and not `()'. `#f' is the canonical non-value in Scheme,
4017 right?
4018
4019 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4020
4021 * struct.c (struct_printer): New variable that holds a handle on
4022 the Scheme variable *struct-printer*. This variable can be set by
4023 Scheme code to override the printing of structures.
4024 (scm_print_struct): If struct_printer is set, call it. If it is
4025 not set, or returns #f, print the structure in the old fashion.
4026 Include "eval.h" for scm_apply.
4027
4028 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4029
4030 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4031 scm_struct_i_n_words to get the number of fields, not
4032 -scm_struct_n_extra_words.
4033
4034 On the route to fancier struct printing:
4035 * struct.c (scm_print_struct): New function to print a structure.
4036 Include "genio.h" to support it. This function doesn't do
4037 anything interesting right now, but I think it should be here
4038 anyway.
4039 * struct.h: Include "print.h" and add prototype for
4040 scm_print_struct.
4041 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4042 print structures ourself.
4043
4044 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4045
4046 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4047 before applying the handler in case it doesn't return.
4048
4049 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4050
4051 * scmsigs.h, async.h: updated.
4052
4053 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4054 loop.
4055
4056 * posix.c (scm_uname): interpret only negative values as an error.
4057 Solaris normally returns a positive value.
4058
4059 * script.c (scm_compile_shell_switches): if we are not going into
4060 an interactive repl, set scm_mask_ints to zero so that asyncs can
4061 run.
4062
4063 * simpos.c (scm_system): don't ignore/unignore signals around
4064 the "system" call.
4065
4066 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4067 the "popen" call.
4068
4069 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4070 done in boot-9.scm instead.
4071
4072 * scmsigs.c, async.c: Major rewriting of signal handling code.
4073 (scm_sigaction): new procedure.
4074 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4075 timing.
4076 (scm_raise): return unspecified, throw error on failure.
4077
4078 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4079
4080 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4081 feature, to help boot-9.scm decide whether to import the regex
4082 module.
4083
4084 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4085
4086 * eval.c: Include scmconfig.h at the beginning of the file so that
4087 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4088 pointing this out.
4089
4090 * regex-posix.c: #include "_scm.h" before conditionally #including
4091 <regex.h>; the former defines HAVE_REGCOMP.
4092
4093 * regex-posix.c: #include <regex.h> conditionally, so the file is
4094 CPP'able (for dependency scanning) even on systems that don't have
4095 a <regex.h> header.
4096
4097 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4098
4099 Add new R4RS-compliant syntax for keywords.
4100 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4101 regardless of the setting of the `keywords' read option.
4102 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4103 can be re-read no matter what the setting of the `keywords' read
4104 option.
4105
4106 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4107
4108 Add support for POSIX regular expressions.
4109
4110 * regex-posix.c, regex-posix.h: New files. (Some code
4111 is taken liberally from rx/rgx.c in the old Guile dist.)
4112
4113 * init.c: Include regex-posix.h.
4114 (scm_boot_guile_1): Call scm_init_regex_posix.
4115
4116 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4117 Add regex-posix.[ch] sources.
4118 * Makefile.in: Regenerated.
4119
4120 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4121 to do this automatically? It didn't for me, bleh.)
4122
4123 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4124
4125 * fports.c (print_pipe_port): New function.
4126 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4127 latter doesn't even take the right arguments.
4128
4129 * Makefile.am: Increment shared lib revision number. I think
4130 sometimes the uninstalled Guile finds the installed shared lib;
4131 Gord says doing this might help. As things turned out, I can't
4132 say whether it does.
4133 * Makefile.in: Regenerated.
4134
4135 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4136 passing it as the closure argument to scm_boot_guile. (Bill
4137 Janssen)
4138
4139 * ports.c (print_void_port, putc_void_port, puts_void_port,
4140 write_void_port, flush_void_port, getc_void_port, close_void_port,
4141 noop0): Use ANSI prototypes instead of K&R declarations, so the
4142 initialization of void_port_ptob gets aggressively type-checked.
4143 Fix arguments of print_void_port and write_void_port. (Bill
4144 Janssen)
4145
4146 * COPYING, __scm.h, _scm.h, alist.c, alist.h, append.c, append.h,
4147 appinit.c, arbiters.c, arbiters.h, async.c, async.h, backtrace.c,

4174 version.c, version.h, vports.c, vports.h, weaks.c, weaks.h: New
4175 address for FSF.
4176
4177 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4178
4179 * script.c (scm_find_executable): Use prototype-style definition
4180 here; apparently it's not quite right to have const in a prototype
4181 and then use a K&R declaration. I wonder if stuff like this will
4182 go away if we compile with -Wrequire-prototypes, or whatever that
4183 is... (Bernard URBAN)
4184
4185 * scmhob.h: New text from Bernard URBAN.
4186
4187 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4188
4189 * script.c: Don't #define const on hpux. Configure takes care of
4190 this. (Thanks to Larry Schwimmer.)
4191
4192 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4193 decide whether to #include <unistd.h>, instead of listing a bunch
4194 of systems. Don't #include stdio twice. Removed dyked-out
4195 definition of scm_find_impl_file.
4196
4197 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4198
4199 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4200 library version info to 1:0.
4201 * Makefile.in: Regenerated.
4202
4203 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
4204 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
4205 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,
4206 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
4207 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4208 throw.c: Update copyright years; these files have been worked on
4209 significantly in 1997, but only had copyright years for 1996.
4210 Also, change name of copyright holder on some from Mikael
4211 Djurfeldt to Free Software Foundation; he has signed papers
4212 assigning the changes to the FSF.
4213
4214 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4215 reason not to give the user the option.
4216
4217 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4218 Return #f on end-of-file when scanning table (i.e. when called
4219 with no arguments). Try to catch errors, when we can.
4220 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4221
4222 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4223 external declarations. These are useful.
4224
4225 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4226
4227 * posix.c: don't include <sys/select.h> or define macros for
4228 select, since they were not used in this file.
4229
4230 * filesys.c (scm_select): make the fifth parameter microseconds,
4231 not milliseconds. let the fourth parameter be either a real value
4232 or an integer or #f. The first, second and third arguments can
4233 now be vectors: the type of the corresponding return set will be
4234 the same.
4235 (set_element, get_element): new static procedures.
4236
4237 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4238
4239 * strports.c (scm_eval_string): New function.
4240 (scm_eval_0str): Trivially re-implemented in terms of
4241 scm_eval_string.
4242 * strports.h (scm_eval_string): New extern decl.
4243
4244 * net_db.c (h_errno): Add extern decl for this.
4245
4246 * fports.c (local_pclose): New function.
4247 (scm_pipob): Use it in the initializer here.
4248
4249 From Tim Pierce:
4250 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4251 Use a meaningful error message when signalling an error. For
4252 this, scm_gethost must check h_errno rather than errno.
4253
4254 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4255
4256 * Makefile.in: Regenerated, using automake-1.1p.
4257
4258 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4259
4260 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4261 not SCM_UNSPECIFIED.
4262
4263 * script.c (scm_compile_shell_switches): don't append (quit) if
4264 interactive.
4265 (scm_shell): call scm_exit_status and exit on the result of the
4266 evaluation.
4267
4268 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4269
4270 Ensure that shared substrings are handled properly when passed to
4271 a system call or other foreign function. Many thanks to Tim
4272 Pierce!
4273 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4274 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4275 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4276 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4277 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4278 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4279 (scm_display_error_message): use RO macros when strings may be RO.
4280 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4281 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4282 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
4283 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
4284 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
4285 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
4286 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4287 scm_strftime), vports.c (scm_make_soft_port): use
4288 SCM_COERCE_SUBSTR to make sure shared substrings are
4289 null-terminated.
4290
4291 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4292
4293 * error.c (scm_error): Add newline to error message.
4294
4295 * init.c (scm_init_standard_ports): Doc fix.
4296
4297 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4298
4299 * dynl-shl.c: Completely replaced with new code from Bernard
4300 URBAN.
4301
4302 * script.c (scm_ice_9_already_loaded): New variable.
4303 (scm_compile_shell_switches): Use it.
4304
4305 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4306
4307 * filesys.c (scm_input_waiting_p): add missing third argument to
4308 scm_misc_error.
4309
4310 * stime.c (scm_localtime): copy the result of localtime before
4311 calling gmtime in case they share a buffer.
4312 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4313 nor HAVE_TZNAME.
4314
4315 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4316
4317 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4318
4319 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4320
4321 * Makefile.am (check-local): New target, which causes 'make check'
4322 to run gh_test_c and gh_test_repl, with some trivial input.
4323 * Makefile.in: Rgnrtd.
4324
4325 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4326
4327 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4328 been unlinked.
4329
4330 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4331
4332 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4333 sure how this was supposed to work.
4334 (scm_async_click): don't send SCM_TICK_SIGNAL.
4335 (scm_init_async): don't initialize %tick-thunk.
4336
4337 * the following change doesn't affect the Scheme interface:
4338 gc-thunk is called at the end of garbage collection. however it's
4339 no longer implemented by pretending it's a signal.
4340
4341 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4342 system async corresponding to scm_gc_thunk.
4343 * async.h: declare scm_gc_async.
4344 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4345 gc-thunk directly, instead of going through a signal handler.
4346 (scm_gc_async): new variable, points to the GC system-async.
4347 (scm_init_async): save the GC async as scm_gc_async instead
4348 of using system_signal_asyncs.
4349 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4350
4351 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4352
4353 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4354 Don't screw up if we're interrupted.
4355 * Makefile.in: Regeneradet.
4356
4357 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4358
4359 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4360
4361 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4362 we're not using AM_INIT_GUILE_MODULE any more.
4363 * Makefile.in: Reneregated.
4364
4365 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4366
4367 Functions for finding variable bindings, grace à Tim Pierce.
4368 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4369 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4370
4371 Get 'make dist' to work again.
4372 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4373 * Makefile.in: Regenerated, like a surry without a fringe on top.
4374
4375 Changes for reduced Guile distribution: one configure script,
4376 no plugins.
4377 * configure.in, configure: Removed.
4378 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4379 real configure script lives.
4380 * Makefile.in, scmconfig.h.in: Regenerated.
4381
4382 * init.c: #include "script.h", to get prototype for script.c's
4383 init function.
4384
4385 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4386
4387 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4388 scm_must_malloc, not raw malloc.
4389
4390 * script.c (scm_compile_shell_switches): Dyke out debugging output
4391 code.
4392
4393 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4394
4395 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4396
4397 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4398 system has them. Hope this is safe. Previously
4399 sys/timeb.h was included if HAVE_FTIME was defined or if
4400 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4401 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4402
4403 * ioext.c (scm_setfileno): add missing third argument to
4404 scm_misc_error call.
4405
4406 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4407
4408 * eq.c (scm_equal_p): Correctly compare strings of different
4409 varieties. (Thanks to Tim Pierce.)
4410
4411 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4412
4413 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4414 #! block comment must occur on a line all by itself.
4415
4416 Move most of the guts of shell command processing into libguile,
4417 so guile.c can be very small (and eventuallly auto-generated. (I
4418 mean, generated mechanically, not self-generated. Hmm.))
4419 * guile.c, script.c, script.h: New source files.
4420 * init.c (scm_boot_guile_1): Call scm_init_script.
4421 * libguile.h: #include "script.h".
4422 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4423 targets, for new executable.
4424 (libguile_la_SOURCES): Mention script.c.
4425 (modinclude_HEADERS): Add script.h.
4426 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4427 not dynamic linking is enabled. This is because we're generating
4428 executables now. Move CY_AC_WITH_THREADS call after those, so the
4429 values of cy_cv_threads_libs captures the libs chosen above.
4430 * Makefile.in, configure, aclocal.m4: Regenerated.
4431
4432 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4433 We don't maintain this interface any more, and it just confuses
4434 people.
4435
4436 * alloca.c: #include <scmconfig.h>, not <config.h>.
4437 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4438 it'll get included in disties.
4439
4440 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4441
4442 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4443 be distributed, because they confuse people.
4444 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4445
4446 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4447
4448 * configure.in: check for presence of gethostent (not present on
4449 OpenBSD by default).
4450 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4451 * configure, scmconfig.h.in: Regenerated.
4452
4453 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4454
4455 * backtrace.c (scm_backtrace): Split message string across
4456 newlines properly. GCC is more tolerant of this than other
4457 compilers.
4458
4459 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4460
4461 Merge threads directory into libguile.
4462 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4463 threads.h: New source files.
4464 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4465 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4466 here; see comment.
4467 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4468 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4469 coop-threads.c.cygnus, coop-threads.h.cygnus.
4470 * configure.in: If we're using threads, include threads.o in
4471 LIBOBJS.
4472 * _scm.h, libguile.h: threads.h lives in this directory now.
4473 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4474 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4475 currently used, but brought along for information's sake.
4476 * ChangeLog-threads: log from old 'threads' directory.
4477 * Makefile.in, configure: Rebuilt.
4478
4479 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4480
4481 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4482 lt->tm_zone.
4483
4484 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4485
4486 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4487
4488 Merge GH interface library into libguile.
4489 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4490 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4491 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4492 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4493 _scm.h to ...
4494 (EXTRA_libguile_la_SOURCES): ... here.
4495 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4496 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4497 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4498 New variables, describing how to build the gh test programs.
4499 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4500 build the test programs, and we probably should have been linking
4501 libguile.la against them all along, to support AIX shared libs.
4502 Add cflags for threads to CFLAGS; add libs for threads to new
4503 variable THREAD_LIBS, used in Makefile.am.
4504 * ChangeLog-gh: log from old `gh' subdirectory.
4505 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4506
4507 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4508
4509 * acconfig.h: Undo change of Apr 9; including the definition of
4510 PACKAGE in the guile headers conflicts with applications' own
4511 definitions.
4512 * scmconfig.h.in: Regenerated.
4513
4514 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
4515
4516 * filesys.c (scm_fcntl): New function from Roland McGrath.
4517 (scm_init_filesys): New symbols for use with fcntl.
4518 * filesys.h: Added prototype.
4519
4520 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
4521 when PROC is receiving no arguments.
4522
4523 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4524
4525 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4526 have S_IFSOCK. This is the case under Ultrix.
4527
4528 * posix.c (scm_status_exit_val, scm_status_exit_val,
4529 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4530 Ultrix versions of WIFSTOPPED, etc., which assume that their
4531 arguments are lvalues (hmm).
4532
4533 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4534
4535 * eval.c: Doc fixes.
4536
4537 * throw.c: Doc fixes; rearranged.
4538
4539 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
4540
4541 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
4542
4543 * acconfig.h: Added entry for PACKAGE.
4544 * scmconfig.h.in: Regenerated.
4545
4546 Changes to work with automake-1.1n, which has better libtool support.
4547 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4548 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
4549 difference here?)
4550 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
4551 readability.
4552 * Makefile.in: Rebuild.
4553
4554 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4555
4556 * stime.c (scm_mktime): take an optional zone argument.
4557 (scm_localtime): check putenv return value.
4558 (scm_strftime, scm_strptime): moved from posix.c. move #include
4559 sequences.h too.
4560 stime.h, posix.h: update prototypes.
4561 (bdtime2c, setzone, restorezone): new static procedures.
4562 (scm_mktime, scm_strftime): use them.
4563 (scm_strftime): don't call mktime before strftime. Use
4564 filltime for return value.
4565 (filltime): convert NULL zname to #f.
4566 (scm_strptime): return a count of characters consumed, not
4567 the remaining string.
4568
4569 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4570
4571 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
4572 (scm_mktime): likewise.
4573 Declare *tzname[].
4574 Uncomment localtime and mktime.
4575
4576 * configure.in: add AC_STRUCT_TIMEZONE.
4577
4578 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4579
4580 * stime.c (scm_init_stime): don't define ticks/sec.
4581 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4582 return value problem and is still portable.)
4583
4584 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4585
4586 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4587 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4588 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4589 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4590 cpp_err_symbols.c): Corresponding changes.
4591 * Makefile.in: Regenerated.
4592
4593 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4594
4595 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4596 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4597 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4598 * putenv.c: new file, from sh-utils 1.12.
4599
4600 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4601 since allocation isn't for Scheme objects.
4602 (scm_putenv): copy strings before placing in the environment.
4603
4604 * stime.c (scm_current_time): throw an error if time returns -1,
4605 instead of returning #f.
4606 (scm_get_internal_real_time, scm_get_internal_real_time): use
4607 scm_long2num for return value instead of SCM_MAKINUM.
4608
4609 * stime.h: prototypes updated.
4610
4611 * stime.c (scm_time_in_msec): apparently unused, deleted.
4612
4613 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4614
4615 * configure.in: check for gettimeofday.
4616
4617 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4618 which may be more usefully portable than a gettimeofday interface.
4619
4620 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4621
4622 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
4623 cpp_err_signals.
4624 * Makefile.in: Regenerated.
4625
4626 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4627
4628 * stime.c (filltime): recovered static procedure.
4629 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4630 an earlier Guile.
4631
4632 * posix.h: add prototype for scm_close_pipe, remove prototypes for
4633 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
4634
4635 * posix.c (scm_mknod): split the mode argument into type and perms
4636 arguments, like the extra fields returned by stat.
4637
4638 * fports.c (scm_pipob): set the close, free and print procedures.
4639 (scm_close_pipe): new procedure.
4640
4641 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
4642 define them in boot-9.scm
4643
4644 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4645
4646 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4647 wan't defined. Don't include fd.h.
4648
4649 * Previously fd.h was regenerated whenever configure was run,
4650 forcing a couple of files to be recompiled.
4651
4652 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
4653 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
4654 Check for _fileno as well as _file.
4655 Don't output fd.h.
4656 * ioext.c: don't fd.h.
4657 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
4658 other to FD_SETTER.
4659
4660 * Change the stratigy for getting information about errno
4661 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
4662 generating lists of symbols during the build process, which will
4663 not always work, include comprehensive lists in the distribution.
4664 To help keep the lists up to date, the "check_signals" and
4665 "check_errnos" make targets can be used.
4666
4667 * configure.in: don't check for a command to extract errno codes.
4668 * Makefile.am: update file lists, remove errnos.list and errnos.c
4669 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
4670 check_errnos targets.
4671 (CLEANFILES): remove errnos.c and errnos.list, add
4672 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
4673 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
4674 * errnos.default: deleted.
4675 * cpp_signal.c: new file.
4676 * cpp_errno.c: renamed from errnos_get.c.
4677 * cpp_err_symbols, cpp_sig_symbols: new files.
4678 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
4679 * error.c (scm_init_error): #include cpp_err_symbols instead of
4680 errnos.c.
4681 * posix.c (scm_init_posix): don't intern signal symbols. #include
4682 cpp_sig_symbols.c.
4683
4684 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
4685
4686 * strop.c (scm_i_index): allow the lower bound to be equal to the
4687 length of the string, so a null string doesn't always give an error.
4688
4689 * posix.h: new prototypes.
4690 * posix.c (scm_status_exit_val, scm_status_term_sig,
4691 scm_status_stop_sig): new functions, as in scsh. They break down
4692 process status values as returned by waitpid.
4693
4694 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
4695
4696 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
4697 configure doesn't know about it.
4698
4699 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4700
4701 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
4702
4703 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
4704 which defines C variables with global linkage.
4705
4706 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4707
4708 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
4709 zero arg subrs.
4710
4711 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
4712
4713 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
4714 has time to check why this doesn't work well with continuations.
4715
4716 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
4717
4718 * Fix shell syntax error; some shells won't tolerate
4719 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
4720
4721 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4722
4723 * posix.c (scm_uname): throw an error if uname fails instead
4724 of returning errno.
4725
4726 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
4727
4728 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
4729 removed.
4730
4731 * async.c (scm_ints_disabled): definition moved from error.c.
4732
4733 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4734
4735 * acconfig.h: Removed PACKAGE.
4736
4737 * scmconfig.h.in: Regenerated.
4738
4739 * snarf.h: g++ says it's non-portable not to specify the first
4740 argument in a varargs declaration. I introduced the first
4741 argument by using preprocessor conditionals.
4742
4743 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
4744
4745 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
4746 (scm_freopen): use RO string macros for filename and modes.
4747 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
4748
4749 * posix.c (scm_getgrgid): simplify conversion of name to C string.
4750 (scm_mknod): use RO string macros for path.
4751
4752 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
4753 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
4754
4755 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4756 use SCM_ROSTRINGP and SCM_ROCHARS.
4757
4758 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4759
4760 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
4761 a scm_tc7_byvect.
4762
4763 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
4764 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
4765 support for byte vectors.
4766
4767 * print.c (scm_iprin1): Limit number of vector elements printed
4768 according to pstate->length.
4769
4770 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
4771
4772 * backtrace.c (scm_display_error_message): don't segv if message
4773 is an immediate.
4774
4775 * error.h: prototype for scm_error_scm.
4776
4777 * error.c (scm_error_scm): new procedure, reimplements scm-error
4778 in C and uses scm_error.
4779
4780 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
4781
4782 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
4783 pointer to the Scheme variable read-hash-procedures and intern it
4784 in scm_init_read. Modify scm_read_hash_extend and
4785 scm_get_hash_procedure to use the pointer.
4786
4787 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4788
4789 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
4790 (SCM_KEYWORD_STYLE): defined.
4791
4792 * read.c (scm_read_opts): add a keywords option. This isn't a
4793 boolean option, in case someone wants to add support for DSSSL
4794 keywords too.
4795 Setup scm_keyword_prefix symbol.
4796 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
4797 set to 'prefix.
4798 I've left keyword support disabled by default, since it doesn't
4799 seem to break the module system and it gives R4RS standard behaviour.
4800 It can be reactivated with (read-set! keywords 'prefix).
4801
4802 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4803
4804 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
4805 before constructing arbiter.
4806
4807 * eval.c (scm_m_define): Bugfix: Check that the object is a
4808 closure before setting the procedure property!
4809
4810 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
4811
4812 * ports.c: Removed `ungetc-char-ready?'.
4813
4814 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
4815
4816 * read.c (scm_init_read): intitialise scm_read_hash_procedures
4817 (idea from Mikael: make it a pair so scm_permanent object only
4818 called once.)
4819 (scm_read_hash_extend): don't call scm_permanent_object.
4820 (ideas from Mikael): if chr is already in the list, replace its
4821 procedure instead of appending it again. If proc is #f, remove
4822 it from the list.
4823 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
4824
4825 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
4826
4827 * gdbint.c (gdb_read): update scm_lreadr usage.
4828
4829 * load.h: update prototypes.
4830
4831 * load.c (scm_primitive_load, scm_read_and_eval_x,
4832 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
4833
4834 * read.h: add prototype for scm_read_hash_extend. Change args for
4835 other prototypes.
4836
4837 * read.c (scm_read_hash_procedures): new variable.
4838 (scm_read_hash_extend): new procedure.
4839 (scm_get_hash_procedure): new procedure.
4840 (scm_lreadr): use scm_get_hash_procedure instead of an argument
4841 for extended # processing.
4842 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
4843 scm_read_token): remove case_i, sharp arguments. Change callers.
4844
4845 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
4846
4847 * read.h (SCM_N_READ_OPTIONS): increase to 3.
4848 (SCM_CASE_INSENSITIVE_P): define.
4849
4850 * read.c: add case-insensitive option to scm_read_opts.
4851 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
4852 to determine whether to convert symbol case.
4853 (default_case_i): definition removed.
4854 * read.c (scm_read_token): if case_i, downcase ic before doing
4855 anything with it.
4856
4857 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4858
4859 * configure.in: Added configuration option `guile-debug'.
4860 Configure with --enable-guile-debug if you want a bunch of extra
4861 functions used for debugging when developing Guile.
4862
4863 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
4864
4865 * procs.c (make-cclo): New undocumented debugging procedure: Make
4866 compiled closure with internal procedure PROC and length LENGTH.
4867 Only compiled if GUILE_DEBUG is defined.
4868
4869 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
4870
4871 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
4872
4873 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
4874
4875 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
4876 with 3 or more args internally to the evaluator.
4877
4878 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4879
4880 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
4881 with 3 or more args internally to the evaluator. This is mainly
4882 because we don't want to pass entry and exit points of the
4883 debug support twice, but it also seems to increase the speed of
4884 the evaluator for such calls (e. g. (+ 1 2 3)).
4885
4886 * backtrace.c (scm_display_application): New procedure:
4887 display-application; Set fancy printing parameters individually
4888 for different types of display (backtrace, error, application).
4889 (These should of course be customizable!)
4890
4891 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
4892 clear the CHECK-flags.
4893
4894 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4895
4896 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
4897
4898 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4899
4900 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
4901 from pairs with a GLOC in the car.
4902
4903 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
4904 otherwise `symbol-hash' will behave badly.
4905 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
4906 we get segmentation fault!
4907
4908 * symbols.c: Added #include "weaks.h". New functions:
4909 `builtin-bindings' and `builtin-weak-bindings'. (These will be
4910 moved to an extraneous library when we split libguile.)
4911
4912 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4913
4914 * filesys.c (scm_stat): stat now takes fport arguments too as
4915 documented in the manual.
4916
4917 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4918
4919 * debug.c (scm_single_step): Bugfix: Call continuation with
4920 scm_call_continuation instead of throwing to it.
4921
4922 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4923
4924 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
4925 argument wasn't declared to be optional.
4926
4927 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4928
4929 * stime.c (scm_init_stime): Add feature "current-time".
4930
4931 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
4932
4933 * throw.h: prototype for scm_exit_status.
4934 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
4935 args to derive an exit status. Allows (quit) to work from a
4936 script.
4937 (scm_exit_status): new function.
4938 #include "eq.h".
4939
4940 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4941
4942 * eval.c (scm_deval): Removed some old code.
4943 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
4944 with the others.
4945 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
4946 exit-frame traps.
4947
4948 * symbols.c (msymbolize): Bugfix: Must initialize property list to
4949 SCM_EOL.
4950
4951 * procs.c: Introduce the existent C function scm_thunk_p at the
4952 Scheme level as well.
4953
4954 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4955
4956 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
4957 used from C to easily lookup the value of a symbol in the current
4958 module.
4959
4960 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4961
4962 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
4963 scm_init_unif in this file. This will also fix a previous problem
4964 with guile-snarf.)
4965
4966 * configure.in: Added AM_MAINTAINER_MODE
4967
4968 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4969
4970 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
4971 avoid warnings.
4972
4973 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4974
4975 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
4976 source files that are not always included in libguile but should
4977 have their dependencies calculated by automake. This variable is
4978 recognized by automake, no further magic is needed.
4979 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
4980 to deal exclusively with *.lo files, as it seems. The *.o files
4981 are built automatically when the corresponding *.lo file gets
4982 built.
4983
4984 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
4985
4986 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
4987 exists.
4988
4989 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
4990
4991 * unif.c (scm_array_set_x): minor change to argument error checking.
4992
4993 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
4994
4995 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
4996 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
4997 They should only be included in the library at configure.in's
4998 discretion.
4999 (libguile_la_LDADD): Include the appropriate .lo files here.
5000 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5001 so we know when to build them (and their .lo bretheren).
5002 * configure.in (LIBLOBJS): New substituted variable. We let
5003 configure decide which .o files to include in LIBOBJS, and then
5004 put the corresponding list of .lo files in LIBLOBJS. The latter
5005 is what we pass to libtool.
5006 * Makefile.in, configure: regenerated.
5007
5008 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5009
5010 * symbols.c (scm_sysintern0): New function. Contains the core of
5011 old scm_sysintern but doesn't take a second value argument.
5012 (scm_sysintern): Now uses scm_sysintern0.
5013 (scm_sysintern_no_module_lookup): Renamed to
5014 scm_sysintern0_no_module_lookup and doesn't take a second value
5015 argument any longer.
5016
5017 * symbols.h (scm_sysintern0: Added declaration.
5018
5019 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5020 scm_sysintern when interning option keys. Otherwise we risk
5021 destroying the values of already interned variables.
5022
5023 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5024 scheme-level boolean (use SCM_NFALSEP).
5025
5026 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5027 `the-last-stack'.
5028 (scm_backtrace): New function. (C version of old function from
5029 boot-9.scm) Motivation: Make it possible to display backtraces
5030 without depending on boot-9.scm. (I'm uncertain if this
5031 motivation is good enough...)
5032
5033 * root.h (scm_root_state): Add member the_last_stack_var.
5034 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5035
5036 * root.c (mark_root): Mark scm_the_last_stack_var.
5037
5038 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5039 SCM_BOOL_F.
5040
5041 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5042
5043 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5044 1. mark_lazy_catch didn't mark the smob.
5045 2. Both functions above have standard variants:
5046 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5047 free_lazy_catch --> scm_free0.
5048
5049 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5050
5051 * throw.c (scm_internal_lazy_catch): New function.
5052 (scm_lazy_catch): Rewritten to use it.
5053 (scm_ithrow): Handle the new lazy catch representation.
5054 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5055 that doesn't have a jmpbuf is a lazy catch clause.
5056 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5057 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5058 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5059 smob.
5060 (scm_init_throw): Register the new lazy-catch smob type.
5061 * throw.h (scm_internal_lazy_catch): decl for new function.
5062
5063 * throw.c (scm_internal_catch): Doc fixes.
5064
5065 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5066 configure.in. Including this might cause problems if applications
5067 that link against libguile include their own copies of alloca, but
5068 if they're using autoconf, they should be adding libguile to LIBS
5069 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5070 the copy in libguile, and things will be okay. (I think.)
5071
5072 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5073
5074 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5075 unif.c.
5076 strop.h: move prototypes too.
5077
5078 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5079
5080 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5081 elsewhere.
5082
5083 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5084 etc. I deleted them from filesys.c long ago, but didn't
5085 notice they were here too (although ineffective since
5086 sys/stat.h wasn't included).
5087
5088 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5089
5090 * eval.c: Don't define alloca in GCC case. gcc will automatically
5091 use __builtin_alloca if appropriate.
5092
5093 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5094
5095 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5096 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5097 that values of automatic variables are preserved. See comments
5098 for safe_setjmp for details.
5099
5100 Change from Thomas Morgan:
5101 * variable.c: Include eq.h.
5102 (var_equal): New function.
5103 (variable_smob): Use var_equal as the discriminator for variables.
5104
5105 * throw.c (s_throw): Remove extraneous declaration.
5106
5107 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5108 * eval.c: Add necessary CPP cruft to support that.
5109 * configure, Makefile.in, scmconfig.h.in: regenerated.
5110
5111 Change from Thomas Morgan:
5112 * procprop.c (scm_procedure_properties): Convert the Scheme
5113 boolean returned by scm_procedure_p into a C boolean before using
5114 it as a condition for SCM_ASSERT.
5115 (scm_procedure_property): Likewise.
5116
5117 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5118 indications of Unixness.
5119 * stime.c: Same.
5120
5121 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5122
5123 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5124
5125 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5126
5127 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5128 "unknown # object" error messages.
5129
5130 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5131 (scm_i_index) and declare it static. Add a 'direction' argument
5132 to indicate what way the search should go.
5133 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5134 if indices are bad.
5135 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5136 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5137
5138 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5139
5140 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5141
5142 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5143 to avoid clash with various scsh forks.

5145 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5146
5147 The following two changes (ramap.c, throw.c) are motivated by the
5148 apparent unportability of forward declarations of static arrays of
5149 the form `static foo bar[];'.
5150
5151 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5152 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5153
5154 * throw.c (scm_throw): Moved above scm_ithrow.
5155
5156 * options.h: Removed the extern declarations of scm_yes_sym and
5157 scm_no_sym since these are static.
5158
5159 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5160
5161 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5162
5163 * Makefile.am: remove AWK=@AWK@.
5164 Add a rule for generating errnos.list.
5165 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5166
5167 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5168 don't extract errnos, just set a variable (avoids the
5169 need to recompile error.c just because configure is run.)
5170
5171 * unif.h: update prototypes.
5172 * unif.c (scm_uniform_array_read,write): change the offset and
5173 length arguments to start and end, for consistency.
5174
5175 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5176
5177 * ioext.h: update prototypes.
5178 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5179 scm_read_line_x, it's a more general procedure using an
5180 interface from scsh. read-line and read-line! are now defined
5181 in boot-9.scm.
5182 Note that the new read-line trims the terminator
5183 by default, previously it was appended to the returned string. An
5184 optional argument specifies how to process the terminator (scsh
5185 compatible). For the old behaviour: (read-line port 'concat).
5186 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5187 returns a pair, but is converted to multiple values if the scsh
5188 module is loaded.
5189
5190 socket.h: update prototypes.
5191 * socket.c (scm_recvfrom): for consistency with other procedures,
5192 take start and end as separate optional arguments.
5193 (scm_recv, scm_recvfrom): don't allow the second argument
5194 to be a size, only a buffer. Change the scheme names to
5195 recv! and recvfrom!. Don't return the buffer.
5196
5197 * ioext.h, posix.h: move prototypes too.
5198 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5199 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5200 "read.h" and "unif.h".
5201 * ioext.c: include "chars.h"
5202
5203 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5204
5205 * dynl.c: The dynamic linking and module registration functions
5206 are now defined even when dynamic linking is not available for the
5207 host system. Some of their functionality can be done without
5208 dynamic linking; when it's really needed, they throw errors.
5209
5210 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5211
5212 * configure.in: Only define DYNAMIC_LINKING when one of the system
5213 dependent functions is detected.
5214 * dynl.c (scm_dynamic_func): New function to get the address of a
5215 function in a dynamic object.
5216 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5217 produced by scm_dynamic_func as the thing to call.
5218
5219 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5220
5221 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5222 (scm_register_module_xxx, scm_registered_modules,
5223 scm_clear_registered_modules): New functions.
5224
5225 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5226
5227 * symbols.c (scm_sysintern): Renamed to
5228 scm_sysintern_no_module_lookup.
5229 (scm_sysintern): New function to take the place of the old
5230 scm_sysintern. It uses the current toplevel lookup closure to give
5231 the symbol its value. This is a temporary hack to put packages
5232 like gtcltk into their own module.
5233 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5234 us whether `scm_top_level_lookup_closure_var' has been initialized
5235 and is usable.
5236 * eval.c (scm_init_eval): Set it.
5237
5238 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5239
5240 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5241 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5242 SCM_FD.
5243 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5244 scm_syserror_msg.
5245 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5246 scm_sys_dup): deleted: FD capability will be added to other
5247 procedures.
5248 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5249 scm_fd_free, fd_smob, scm_intern_fd.
5250 (scm_open): renamed from scm_sys_open. Return a port instead of
5251 an FD object. Make the mode argument optional.
5252 (scm_sys_create): deleted, it's just a special case of open.
5253 (scm_init_filesys): move interning of constants O_CREAT etc.,
5254 here (were previously using SCM_CONST_LONG macro).
5255 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5256 don't newsmob fd.
5257 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5258 include "fports.h" and <stdio.h>
5259 (scm_stat, scm_select): don't support FD objects.
5260
5261 * error.h: adjust scm_syserror_msg prototype.
5262 * error.c (scm_syserror_msg): take an extra argument for errno.
5263 Using the global value didn't always work, since it could be
5264 reset by procedure calls in the message or args arguments.
5265
5266 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5267 I don't understand why the check was there (and what about the
5268 ultrix check?)
5269
5270 * strop.c (scm_string_copy): allow shared substrings to be copied.
5271
5272 * unif.h: corresponding change to prototypes.
5273 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5274 recognize two new optional arguments: offset and length. Allow
5275 the port argument to be an integer (file descriptor, for scsh).
5276 Include <unistd.h> for "read" prototype.
5277
5278 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5279
5280 * socket.c: don't include filesys.h.
5281
5282 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5283
5284 * Makefile.am: add AWK=@AWK@ (?)
5285
5286 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5287 errnos_get.c.
5288 Add a rule to generate errnos.c from errnos.
5289 * error.c (scm_init_error): include errnos.c.
5290 * errnos_cnvt.awk: new file, converts the list of errno codes to
5291 C expressions.
5292 * errnos_get.c: new file.
5293 * errnos.default: new file, contains errnos to try if they can't
5294 be extracted from errno.h.
5295 * configure.in: if using GCC, try and extract errno codes from
5296 errno.h.
5297 Added AC_PROG_AWK.
5298
5299 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5300
5301 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5302 * Makefile.am: Made libguile into a libtool library.
5303 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5304 Set libtool_libs to indicate that libguile is a libtool library.
5305 See guile/ChangeLog for details.
5306 * .cvsignore: ignore "*.lo", the libtool library objects.
5307
5308 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5309
5310 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5311 use htons in getservbyport argument.
5312
5313 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5314
5315 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5316 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5317 duplicate.
5318
5319 * objprop.c (scm_object_property): No need to take the CDR of the
5320 value returned by scm_object_properties, since Aug 20 change.
5321
5322 * configure.in: When checking for struct linger, #include
5323 <sys/types.h> as well as <sys/socket.h>. I've never known
5324 <sys/types.h> to cause any portability problems, and Solaris's
5325 <sys/socket.h> needs it.
5326 * configure: Rebuilt.
5327
5328 I think the Sun compiler has chosen a perverse way to interpret
5329 ANSI declarations combined with K&R definitions. We'll
5330 appease it a little bit. But when it invades France, we fight.
5331 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5332 * print.h (scm_iprlist): Here too.
5333 * numbers.c (scm_divbigdig): Change definition to match
5334 declaration in numbers.h.
5335 * unif.c (scm_makflo): Change definition to match declaration in
5336 unif.h.
5337
5338 * init.c (scm_boot_guile): Don't return the value of
5339 scm_boot_guile_1. This function doesn't return a value;
5340 scm_boot_guile_1 doesn't return a value (or return at all).
5341
5342 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5343 compiler.
5344
5345 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5346 compile. I have a feeling this function is a bad idea anyway ---
5347 one should always test for features, not systems.
5348
5349 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5350 semicolons. Only pure luck kept this from being noticed earlier.
5351
5352 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5353
5354 * socket.c (scm_recvfrom): Added missing semicolon.
5355
5356 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5357
5358 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5359 the buffer and start and end positions for scsh networking
5360 implementation.
5361
5362 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5363
5364 * configure.in: Revert previous change to this file; the problem
5365 is due to transient automake weirdness.
5366 * configure: Rebuilt.
5367
5368 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5369 PLUGIN/guile.libs. configure generates the latter from the former.
5370 * Makefile.in: Rebuilt.
5371
5372 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5373 need this if we install scripts, like guile-snarf.
5374 * configure: Rebuilt.
5375
5376 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5377
5378 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5379
5380 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5381
5382 * socket.c (scm_addr_vector): fix faulty scm_listify.
5383
5384 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5385
5386 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5387 style block comment is no longer considered an error.
5388
5389 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5390
5391 * PLUGIN/guile.libs.in: New file.
5392 * PLUGIN/guile.libs: Removed from repository.
5393 * configure.in: Create PLUGIN/guile.libs from
5394 PLUGIN/guile.libs.in. This is for including additonal libraries
5395 needed for dynamic linking.
5396 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5397 instead of PLUGIN/guile.libs.
5398
5399 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5400
5401 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5402
5403 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5404 occurrences of the given element from the list, not just the
5405 first. This is how the Emacs Lisp functions behave, how the
5406 analogous Common Lisp functions behave, and (I believe) how the
5407 older Maclisp functions worked. I realize that this change may
5408 break code, but it seemed better to break it before the Guile
5409 release than after.
5410
5411 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5412 Their prototypes were already present in gc.h, but they weren't
5413 implemented.
5414 (scm_init_storage): Initialize scm_protects.
5415 * root.c (scm_protects): New element of scm_sys_protects.
5416
5417 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5418
5419 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5420
5421 * libguile.h: Added #include "libguile/net_db.h".
5422
5423 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5424 30 change. That file is only meant for communication between the
5425 configuration process and load.c. If code linked against libguile
5426 wants to get at the paths mentioned in libpath.h, it can call
5427 functions declared in load.h.
5428
5429 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5430
5431 * libguile.h: Removed #include "libguile/fdsocket.h"
5432
5433 * net_db.c: Added #include <sys/socket.h>.
5434
5435 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5436
5437 * filesys.c (scm_input_waiting_p): use select in preference to
5438 FIONREAD, since the latter doesn't detect EOF.
5439 Throw error if neither select nor FIONREAD available.
5440
5441 * socket.c (scm_connect): take a port, not a fd object.
5442 (scm_fill_sockaddr): throw an error if fam is not recognised.
5443 (scm_bind): use scm_fill_sockaddr.
5444 (scm_listen): take a port, not a fd object.
5445 (scm_accept): take and return a port. return #f in the car if
5446 address can't be got
5447 (scm_sock_fd_to_port): new procedure.
5448 (scm_socket): use scm_sock_fd_to_port.
5449 (scm_addr_vector): throw error if unrecognised address type.
5450 take an extra argument with the calling procedure name.
5451 (scm_getsockname): take a port. return #f if address can't be got.
5452 (scm_getpeername): take a port. return #f if address can't be got.
5453 (scm_recvfrom): take a port. return #f for address component if can't
5454 be got.
5455 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5456 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5457
5458 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5459
5460 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5461 use separate data pointers, to allow them to be designed
5462 independently and reused.
5463 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5464 Renamed from catch_body, catch_handler, and uncaught_throw; made
5465 generically useful.
5466 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5467 to throw.h.
5468 (scm_catch): Use the above.
5469 (scm_throw): Don't bother printing a message for an uncaught
5470 throw; we establish a default handler in init.
5471 * throw.h (scm_internal_catch): Prototype updated.
5472 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5473 decls.
5474 (struct scm_body_thunk_data): New structure, used as data
5475 argument to scm_body_thunk.
5476 * init.c (struct main_func_closure): New structure, packaging up
5477 the data to pass to the user's main function.
5478 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5479 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5480 scm_internal_catch to establish a catch-all handler, using
5481 scm_handle_by_message. This replaces the special-case code in
5482 scm_throw.
5483 (invoke_main_func): Body function for scm_internal_catch; invoke
5484 the user's main function, using the main_func_closure pointer to
5485 decide what to pass it.
5486 * root.c (struct cwdr_body_data): Remove handler_proc member.
5487 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5488 (cwdr_handler): Removed.
5489
5490 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5491
5492 * socket.h (SCM_P): update bind prototype.
5493 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5494 include "feature.h".
5495 (scm_socket): return a port, not a file descriptor object.
5496 include "fports.h" and <unistd.h>
5497 (scm_bind): take a port, not a file descriptor object.
5498 take an extra argument for address args.
5499
5500 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5501 INADDR_NONE, INADDR_LOOPBACK.
5502
5503 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5504
5505 * init.c: include net_db.h and not fdsocket.h.
5506 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5507
5508 * Makefile.am: corresponding changes.
5509 * socket.h: renamed from fdsocket.h, fix names.
5510 * net_db.h: renamed from socket.h, fix names.
5511 * socket.c: renamed from fdsocket.c.
5512 remove _sys from procedure names.
5513 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5514 add "socket" to features list.
5515 * net_db.c: renamed from socket.c.
5516 remove _sys from procedure names.
5517 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5518 add "net-db" to features list.
5519 include "net_db.h". don't include <sys/socket.h> or
5520 <sys/un.h>.
5521
5522 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5523
5524 * tags.h (scm_tags): Removed comma at end of last enumerator.
5525
5526 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5527
5528 Don't use GCC extensions to allocate space for debugging frames.
5529 (Here he goes again! Why do we put up with this?!)
5530 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5531 an scm_debug_info structure, not an in-line array of them. Add
5532 'info' member, to say how many vect elements we've used, for eval
5533 frames.
5534 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5535 a new variable debug_info_end to mark the end of vect, instead of
5536 the address of the 'info' pointer itself.
5537 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5538 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5539 (SCM_APPLY): Explicitly allocate space for debug.vect.
5540 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5541 * stacks.c: Adjusted for new debug frame structure.
5542 (RELOC_INFO, RELOC_FRAME): New macros.
5543 (stack_depth, read_frames): Use them, and new scm_debug_frame
5544 element 'info', instead of magically knowing that eval frames have
5545 an info pointer sitting after vect.
5546 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5547 RELOC_FRAME.
5548 (scm_init_stacks): Formatting tweaks.
5549
5550 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5551
5552 Give GCC more control flow information, so it can be sure that
5553 variables aren't used uninitialized.
5554 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5555 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5556 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5557 scm_misc_error): Tell GCC that these functions never return.
5558 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5559 out the field type, call abort if SCM_ASSERT returns, to placate
5560 the optimizer.
5561 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5562 scm_wta ever returns. We can't handle this case anyway, and this
5563 gives the optimizer more information.
5564 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5565 scm_wta ever returns.
5566
5567 In some cases, the code is fine, but GCC isn't smart enough to
5568 figure that out; this usually happens when one variable is only
5569 initialized and used when a particular condition holds true, and
5570 we know that condition will never change within a given invocation
5571 of the function. In this case, we simply initialize the variables
5572 to placate the compiler, hopefully to a value which will cause a
5573 crash if it is ever actually used.
5574 * print.c (scm_iprin1): Initialize mw_pos.
5575 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5576 * throw.c (scm_ithrow): Initialize dynpair.
5577 * unif.c (scm_uniform_vector_ref): Initialize cra.
5578 * struct.c (init_struct): Initialize prot.
5579 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5580
5581 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5582 if EXPR contains no expressions.
5583
5584 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5585
5586 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5587 cause an infinite loop (???). So much for the algebraic
5588 equivalency of variable-sized arrays and alloca...
5589
5590 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5591
5592 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5593 a SCM boolean, not a C boolean.
5594
5595 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5596
5597 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5598 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5599 rules for raising scm_mtrigger. Previously, unfortunate but not
5600 unlikely circumstances could result in almost constant invokation
5601 of the gc. Now, this situations should be less likely, but they
5602 are not prevented completely.
5603
5604 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5605
5606 * numbers.c (scm_fuck): Procedure removed; looks like old test
5607 code.
5608 * numbers.h: Prototype removed.
5609
5610 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5611
5612 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5613 array to a pointer, to match my Nov 21 change in eval.c.
5614
5615 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5616
5617 * libguile.h: Added #include "libguile/backtrace.h", #include
5618 "libguile/stacks.h".
5619
5620 * strings.c (scm_string scm_make_string scm_string_ref
5621 scm_string_set_x scm_string_equal_p scm_string_append):
5622 Bugfix according to scm patch from Aubrey Jaffer:
5623 Corrected long-standing
5624 (not (eqv? (integer->char 128)
5625 (string-ref (make-string 1 (integer->char 128)) 0)))
5626 bug found by John Kozak <jk@noontide.demon.co.uk>.
5627
5628 * strports.c, strports.h: Make scm_eval_0str return the value of
5629 the last expression evaluated (previously, it returned void).
5630
5631 * strports.c, strports.h: New function: scm_read_0str. Does what
5632 it sounds like.
5633
5634 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5635
5636 * simpos.c (scm_getenv): return #f if string can't be found in the
5637 environment instead of throwing an exception, for compatibility
5638 with numerous other systems.
5639
5640 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
5641
5642 * Makefile.am (.c.x): Use guile-snarf.
5643 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
5644 executable.
5645 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
5646
5647 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5648
5649 * backtrace.c (scm_display_error_message): Made non-static, and
5650 renamed from display_error_message.
5651 * backtrace.h (scm_display_error_message): Added extern decl.
5652 * throw.c (uncaught_throw): Use it to display the error message.
5653
5654 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
5655
5656 * inet_aton.c: Use #if 0, not #ifdef 0.
5657
5658 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
5659
5660 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
5661 to convert the returned value.
5662 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
5663 the offset argument.
5664
5665 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5666
5667 Add new interface to catch/throw, usable from C as well as
5668 Scheme.
5669 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
5670 (scm_internal_catch): New function, replaces...
5671 (scm_catch_apply): Deleted.
5672 * throw.c (scm_catch_apply): Deleted; replaced with a more general
5673 mechanism which is a bit more code, but can be used nicely from C
5674 and implement the Scheme semantics as well.
5675 (scm_internal_catch): This is the replacement; it's named after
5676 the analogous function in Emacs.
5677 (scm_catch): Reimplemented in terms of the above.
5678 (struct catch_body_data, catch_body, catch_handler): New
5679 functions, used by scm_catch.
5680 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
5681 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
5682 support for new cwdr.
5683
5684 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
5685 Oct 30.
5686
5687 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
5688
5689 * acconfig.h: Added DYNAMIC_LINKING symbol.
5690 * configure.in: Add option and checks for dynamic linking.
5691 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
5692 dynl.h: New files for dynamic linking support.
5693 * Makefile.am (libguile_a_SOURCES):
5694 Added "dynl.c".
5695 (modinclude_HEADERS): Added "dynl.h".
5696 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
5697 "dynl-vms.c".
5698 * init.c (scm_boot_guile_1): Call
5699 scm_init_dynamic_linking to initialize dynamic linking support.
5700
5701 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
5702
5703 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
5704 (as we Schemers say). It needs to be global, so that I can tweak
5705 it for the proper operation of unexec.
5706 (scm_boot_guile_1_live): New variable, see above.
5707
5708 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
5709
5710 * guile-snarf.sh: Removed.
5711 * PLUGIN/guile.libs: Added dependency for -lm.
5712 * acinclude.m4: Renamed from aclocal.m4.
5713 * PLUGIN/greet: Removed.
5714 * Makefile.am, aclocal.m4: New files.
5715 * configure.in: Updated for Automake.
5716
5717 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
5718
5719 * eval.c (scm_definedp): Use top_level_lookup_closure_var
5720 and not top_level_lookup_thunk_var.
5721
5722 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
5723
5724 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
5725
5726 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
5727
5728 * eval.c (scm_definedp): Incompatibly changed to be a builtin
5729 Scheme function, instead of syntax. Single argument is now a
5730 symbol.
5731
5732 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5733
5734 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
5735 scm_ra_divide): Properly terminate statements passed as arguments
5736 to IVDEP macros. (Thanks to Bernard Urban.)
5737
5738 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
5739 with non-constant sizes. (Thanks to Bernard Urban.)
5740
5741 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5742
5743 It's an "eval closure", not an "eval thunk." A thunk is a
5744 function of no arguments.
5745 * root.h (struct scm_root_state): Renamed
5746 top_level_lookup_closure_var from top_level_lookup_thunk_var.
5747 (scm_top_level_lookup_closure_var): Renamed from
5748 scm_top_level_lookup_thunk_var.
5749 * root.c (mark_root): Uses changed.
5750 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
5751 * init.c (scm_start_stack): Uses changed.
5752 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
5753 Change scheme-visible name to *top-level-lookup-closure* from
5754 *top-level-lookup-thunk*.
5755
5756 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
5757
5758 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
5759 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
5760
5761 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
5762
5763 * gc.c (struct scm_heap_seg_data): Doc fixes.
5764
5765 * gc.c (scm_gc_sweep): Empty all segments' freelists before
5766 sweeping. Then, prepend each segment's free cells to its
5767 freelist, rather than wiping out the old value. (Thanks to Marius
5768 Vollmer.)
5769
5770 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
5771 scm_check_freelist, scm_debug_newcell): New functions and
5772 variables, for debugging freelist problems.
5773 * pairs.h (SCM_NEWCELL): New debugging version added.
5774 * gc.h (scm_debug_newcell): Added extern declaration, used by
5775 debugging version of SCM_NEWCELL.
5776
5777 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5778
5779 On some systems <libc.h> conflicts with <unistd.h>, and should not
5780 be #included at all.
5781 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
5782 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
5783 * configure.in: Call it.
5784 * posix.c, filesys.c: Use its results to decide whether or not to
5785 #include <libc.h>.
5786 * configure, scmconfig.h.in: Rebuilt with autoconf and
5787 autoheader.
5788
5789 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5790
5791 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
5792 pointer to the stdio stream before calling scm_setbuf0, so the
5793 latter will be able to retrieve it. I'm surprised this didn't
5794 segfault earlier. (Thanks to Christopher Lee.)
5795
5796 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5797
5798 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
5799 of `lazy-catch'.
5800
5801 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5802
5803 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
5804 number of stack narrowing specifier pairs. The first specifier in
5805 a pair controls inner border, the second the outer border. A
5806 number means cut that number of frames, a procedure object means
5807 cut until that object is found in operator position in a frame.
5808
5809 * root.c (cwdr): Bugfix.
5810
5811 * read.c: Recording of positions disabled by default.
5812
5813 * procs.c (scm_closure_p): New function.
5814
5815 * posix.c (scm_tmpnam): New function.
5816
5817 * load.c: Added #include "throw.h".
5818 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
5819 ends with '/'.
5820
5821 * load.c, load.h (scm_read_and_eval_x): New function.
5822
5823 * eval.c: Renamed debug option "deval" to "debug".
5824
5825 (scm_eval_x): `eval!' is no longer accessible from the scheme
5826 level. Motivation: We can't allow operations which introduce
5827 glocs into the scheme level. Guile's type system can't handle
5828 these as data. Use `eval' or `read-and-eval!' as replacement.
5829
5830 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
5831 SCM_CONSP since this is a macro!; Set vframe.prev to
5832 scm_last_debug_frame instead of 0. In this way we can look
5833 "above" the virtual start stack frame if we wish.
5834 (scm_debug_hang): New function: Useful for debugging Guile in
5835 certain tricky situations. Will probably be removed later...
5836
5837 * debug.h: Changed semantics of debug option "backtrace". This
5838 option now only indicates whether we want automatic backtrace at
5839 an error.
5840
5841 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5842
5843 * ports.c: #include "filesys.h"
5844 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
5845
5846 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
5847 Motivation: This is system specific code which is related to file
5848 I/O. It also may use select. Added code by Gary Houston to
5849 detect presence of character in stdio buffers.
5850
5851 * libguile.h: #include "libguile/libpath.h"
5852
5853 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
5854 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
5855 SCM_SITE_DIR; Install libpath.h among the other include files.
5856
5857 * load.c, load.h (scm_sys_package_data_dir): New function.
5858
5859 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5860
5861 * stacks.h: Bugfix: Don't use tail-array length field as stack
5862 length field! This screwed GC.
5863
5864 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5865
5866 * _scm.h: Added #ifndef around definition of macros min and max.
5867
5868 * __scm.h: Added hooks for threads to plugin to in ints protection
5869 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
5870 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
5871 the main code in these macros duplicated and spread over multiple
5872 files. Renamed SCM_THREADS_SWITCHING_CODE ->
5873 SCM_THREAD_SWITCHING_CODE.
5874
5875 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
5876
5877 * snarf.h: New file.
5878 * guile-snarf.sh: New file.
5879 * Makefile.in (inner_h_files): Added snarf.h
5880 (ancillary, install, uninstall, distclean): Added actions for
5881 guile-snarf.
5882 (.c.x): Use guile-snarf.
5883 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
5884 (gen_c_files): Note that these depend on guile-snarf.
5885 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
5886 now in "snarf.h". Added #include "snarf.h" to get them.
5887 * libguile.h: Added #include "snarf.h".
5888 (Patches applied and tweaked by Jim Blandy.)
5889
5890 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
5891
5892 * socket.c: Use K&R style declaration for 'close'; the GNU coding
5893 standards suggest against providing prototypes for system
5894 functions. Thanks to Greg Troxel.
5895
5896 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5897
5898 * strports.c (scm_eval_0str): New function.
5899 #include "read.h", to get prototype for scm_read.
5900 * Makefile.in (strports.o): Update dependencies.
5901 * strports.h: New prototype.
5902
5903 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
5904 scheme name from "int?" to "integer?". It seems to do the job.
5905 * numbers.h: Rename prototype too.
5906 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
5907 hope this is right.
5908
5909 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
5910 scm_num_eq_p): Rename these according to R4RS conventions: call
5911 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
5912 to making libguile R4RS compliant without ice-9...
5913
5914 * load.c (scm_sys_search_load_path): Search for files under all
5915 extensions listed in the %load-extensions variable. If FILENAME
5916 is absolute, return it unchanged, without searching the load path.
5917 (scm_loc_load_extensions): New variable, pointing to
5918 %load-extensions' value cell.
5919 (scm_init_load): Initialize it, and the value it points to.
5920 (scm_primitive_load_path): Improve error reporting.
5921
5922 * load.c (scm_loc_load_hook): New variable, pointing to value cell
5923 of new Scheme variable %load-hook.
5924 (scm_primitive_load): Apply %load-hook to filename.
5925
5926 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
5927
5928 * configure.in: add tests for figuring out whether buffered data
5929 is available in a FILE structure, which is needed by char-ready.
5930
5931 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
5932 FILE_CNT_READPTR.
5933
5934 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
5935 exceptions using misc_error instead of syserror. It seems a bit
5936 odd to throw an exception if a string can't be found in the
5937 environment, but it's consistent with open-file, stat etc.
5938 (simpos.h): remove sys_ from getenv.
5939
5940 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
5941 occurs, throw an error instead of returning errno. Return value
5942 is now unspecified.
5943 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
5944
5945 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
5946
5947 * filesys.c (scm_stat2scm): derive file type and permissions from
5948 the stat mode and append them to the returned vector.
5949 There isn't much overhead in doing this and it avoids the need to
5950 work with S_IRUSR et al. in Scheme.
5951 Define symbols scm_sym_regular etc.
5952 (scm_init_filesys): don't intern S_IRUSR etc.
5953
5954 * load.c: change s_try_load and s_try_load_path to s_primitive_load
5955 and s_primitive_load_path.
5956
5957 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
5958
5959 * error.h: don't declare error symbols. prototype for scm_misc_error.
5960
5961 * stackchk.c (scm_stack_overflow_key): defined here instead of in
5962 error.c.
5963
5964 * error.c: use SCM_SYMBOL to set up error keys.
5965 scm_misc_error: new procedure.
5966
5967 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5968
5969 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
5970 between `#!' and `!#' is ignored.
5971 (skip_scsh_block_comment): New function.
5972
5973 * feature.c (scm_set_program_arguments): New argument, FIRST.
5974 * feature.h: Update prototype.
5975 * init.c (scm_boot_guile_1): Pass new argument to
5976 scm_set_program_arguments.
5977
5978 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5979
5980 * init.c (scm_start_stack): Don't initialize scm_progargs here.
5981 (scm_boot_guile): Call scm_set_program_arguments here, later than
5982 the old initialization.
5983
5984 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
5985 initialization procedure.
5986 - Delete in, out, err arguments; there are other perfectly good
5987 ways to override these when desired.
5988 - Delete result argument; this function shouldn't ever return.
5989 - Rename init_func argument to main_func, for less confusion.
5990 - Delete boot_cmd argument; main_func is more general.
5991 -Add 'closure' argument, to help people pass data to main_func
5992 without resorting to global variables.
5993 - Abort if reentered; don't bother returning an error code.
5994 - Call scm_init_standard_ports to set up the default/current
5995 standard ports; no need to pass them to scm_start_stack.
5996 - Remove code to evaluate the boot_cmd, and start the repl; let
5997 the user do something like that in main_func if they want.
5998 - Remove code to package up a return value; main_func can do any
5999 of that as needed.
6000 - Call exit (0), instead of returning.
6001 (scm_start_stack): Don't initialize the I/O ports here; that's
6002 weird. Delete in, out, err arguments. Move guts to
6003 scm_init_standard_ports, scm_stdio_to_port.
6004 (scm_init_standard_ports): New function, to set up current and
6005 default standard ports.
6006 (scm_start_stack, scm_restart_stack): Make these static.
6007 * init.h (scm_boot_guile): Adjust declaration.
6008 (scm_start_stack, scm_restart_stack): Remove externally
6009 visible declarations for these.
6010 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6011
6012 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6013 written out several times in scm_start_stack.
6014 * fports.h: New declaration for the above.
6015
6016 * feature.c (scm_set_program_arguments): New function.
6017 * feature.h: New declaration for the above.
6018
6019 * ports.c: Formatting tweak.
6020
6021 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6022
6023 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6024 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6025 for obtaining the address of a car or cdr field. Motivation:
6026 &SCM_CXR make assumptions about the internal structure of the
6027 SCM_CXR selectors.
6028
6029 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6030 Motivation: see SCM_CXRLOC.
6031
6032 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6033 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6034 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6035 Motivation: Safer use. Some other macros are defined in terms of
6036 these operations. If these are defined using the SCM_SETCXR
6037 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6038 to inefficiency and an <e1> with side-effects could potentially
6039 break. Also, these particular operations are heavily utilized in
6040 the garbage collector. In unoptimized code there will be a
6041 measurable speedup.
6042
6043 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6044 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6045 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6046 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6047 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6048 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6049 vports.c: Cleaned up use of pairs: Don't make any special
6050 assumptions about the internal structure of selectors and
6051 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6052 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6053 (Among other things, this change makes it easier to build Guile
6054 with certain compilers which have problems with casted lvalues.)
6055
6056 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6057
6058 * stacks.c: Improve selection of relevant stack frames when making
6059 a stack object. Introduce one level of indirection in the stack
6060 object to make it possible to "narrow" to a certain region of the
6061 stack. This facilitates making use of more clever algorithms (not
6062 implemented) for selecting relevant frames and gives a cleaner
6063 design since selection of frames can be done independently of
6064 extraction of frames from the real stack.
6065 (scm_stack_id): Also take #t as argument which means look at
6066 current stack.
6067
6068 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6069 Turn n_tail into an integer directly representing current number
6070 of frames in stack. Add field tail.
6071
6072 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6073
6074 * debug.c (scm_make_memoized): Made it available at scheme level.
6075 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6076 SCM_NIMP before applying heavier predicates in argument checking.
6077 (scm_local_eval): Also take memoized object as argument.
6078
6079 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6080 aren't created with zero length, but should such a strange
6081 creature suddenly turn up...
6082
6083 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6084
6085 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6086 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6087
6088 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6089
6090 * variable.c (scm_make_variable): Make the name hint optional, as
6091 documented.
6092 (anonymous_variable_sym): Renamed from variable_sym. All uses
6093 changed.
6094
6095 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6096 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6097 of scm_primitive_load_path was also changed to
6098 "primitive-load-path", from "%try-load-path". Callers changed.
6099 We'd like to respect the convention that a function named
6100 "try-mumble" should behave just like the function called "mumble",
6101 but return #f instead of signalling some error.
6102 * load.h: Rename prototypes.
6103
6104 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6105
6106 * print.c (make_print_state, grow_print_state), print.h: Modified
6107 the print state representation: Don't use a tail array for
6108 recording of circular references. Resizing of the print state
6109 structure invalidates the print state pointer. To avoid passing
6110 around an indirect print state reference to all printing
6111 functions, we instead let the print state reference a resizable
6112 vector.
6113
6114 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6115
6116 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6117 Don't crash when passed an improper list terminated by a
6118 non-immediate value.
6119
6120 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6121
6122 Allocate data for structures on an eight-byte boundary, as
6123 required by the tagging system.
6124 * struct.c (alloc_struct): New function.
6125 (scm_make_struct, scm_make_vtable_vtable): Call it.
6126 * struct.h (scm_struct_n_extra_words): Bump to 3.
6127 (scm_struct_i_ptr): New "field".
6128 * gc.c (scm_gc_sweep): When we need to free the data, use the
6129 information stored by alloc_struct to find the beginning of the
6130 block allocated to the structure, so we can free it.
6131
6132 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6133
6134 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6135 scm_init_stacks.
6136
6137 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6138 (scm_debug_info): New member: id.
6139
6140 * stacks.c: Stacks are now represented as structs; Stacks have an
6141 id given to them by `start-stack'.
6142 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6143
6144 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6145 Changed stack representation.
6146
6147 * debug.c (scm_procedure_name): Try procedure property `name' for
6148 compiled closures aswell.
6149
6150 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6151
6152 * eval.c: scm_i_name moved to gsubr.c
6153 (scm_m_define): Record names of all kinds of procedure
6154 objects. (Earlier, only closures were recorded.)
6155
6156 * procprop.h: Added declaration of scm_i_name.
6157
6158 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6159 (scm_make_gsubr): Record names of compiled closures.
6160
6161 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6162
6163 * debug.c, debug.h: Removed obsolete code.
6164
6165 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6166 stacks.c: Renamed regs --> scm_contregs.
6167
6168 * print.c (scm_free_print_state): Cleanup print state before
6169 returning it to pool. It is better to do it here than in
6170 scm_prin1 since scm_prin1 is called often.
6171
6172 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6173 s_set_source_property_x): Check that first argument is a pair or a
6174 memoized object.
6175
6176 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6177 scm_i_line, scm_i_column and scm_i_breakpoint global.
6178
6179 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6180 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6181 scm_init_stacks.
6182
6183 * debug.h: Added debug object smob declaration and macro
6184 definitions.
6185
6186 * configure.in: Build with backtrace.o and stacks.o if debug
6187 support enabled.
6188
6189 * Makefile.in: Added entries for new files: backtrace.c,
6190 backtrace.h, stacks.c and stacks.h.
6191
6192 * symbols.c (scm_sym2ovcell): Fixed documentation.
6193
6194 * _scm.h (min, max): Added.
6195
6196 * async.c: Moved `min' macro to _scm.h.
6197
6198 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6199 SCM_BACKTRACE_INDENT.
6200
6201 * eval.c: Added new debug options `maxdepth' and `indent'.
6202
6203 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6204
6205 * print.h: Added selector SCM_PRINT_STATE.
6206
6207 * print.c: New functions: scm_make_print_state,
6208 scm_free_print_state.
6209
6210 * print.h: Added declarations for scm_make_print_state,
6211 scm_free_print_state.
6212
6213 * debug.c (scm_m_start_stack): New acro.
6214
6215 * debug.h: Small cleanup.
6216
6217 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6218 scm_init_eval.
6219
6220 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6221
6222 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,
6223 arbiters.c, arbiters.h, async.c, async.h, boolean.c, boolean.h,
6224 chars.c, chars.h, continuations.c, continuations.h, debug.c,

6240 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
6241 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
6242 declare functions with prototypes. (Patch thanks to Marius
6243 Vollmer.)
6244
6245 More prototype-related changes from Marius Vollmer:
6246 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6247 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6248 * ports.h (ptobfuns): Added prototypes. This means some casting in
6249 fports.c.
6250 * fports.c: Added casts for initializations, since the functions
6251 are defined to take FILE * as their stream argument, not SCM.
6252 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6253 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6254 to `char *str_data' to conform to prototype.
6255
6256 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6257
6258 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6259
6260 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6261
6262 * stime.c, stime.h: use SCM_P method.
6263
6264 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6265
6266 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6267 be given at least two arguments. Insist that lst's last element
6268 be a list, but don't make any requirements of its predecessors.
6269
6270 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6271
6272 * eval.c (scm_nconc2last): Revert last change; there seems to be
6273 other stuff going on here.
6274
6275 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6276
6277 * eval.c (scm_nconc2last): Make sure that each element of lst
6278 (which is a list of argument lists, except for the tail) is a
6279 proper list, i.e., finite and terminated by '().
6280
6281 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6282
6283 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6284 Clarifies flow.
6285
6286 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6287 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6288 saying "1".
6289
6290 * vectors.c (scm_make_vector): Fill vectors with the undefined
6291 value, to help make Guile Scheme code more portable to other
6292 Schemes.
6293
6294 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6295 * symbols.h, tags.h: Doc fixes.
6296
6297 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6298
6299 * async.c (scm_take_signal): Doc fixes.
6300
6301 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6302
6303 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6304 want to subtract it from the modulus; we just want to leave it
6305 alone.
6306
6307 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6308
6309 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6310 `scm_init_threads'.
6311
6312 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6313
6314 * throw.c (scm_catch_apply): Finished implementation of
6315 `lazy-catch'.
6316
6317 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6318
6319 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6320 check.
6321 (scm_init_filesys): set "i/o-extensions" feature.
6322 include feature.h.
6323
6324 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6325
6326 * Makefile.in (root.o): Correct dependencies.
6327
6328 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6329
6330 * Makefile.in: Added dependency entry for root.o.
6331
6332 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6333 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6334
6335 * init.c (scm_start_stack): Set initial root continuation number
6336 to 0.
6337
6338 * procs.c: New function: scm_thunk_p.
6339
6340 * procs.h: Added declarations of scm_thunk_p.
6341
6342 * root.c: Renamed `call-with-new-root' -->
6343 `call-with-dynamic-root'.
6344 (cwdr): Removed allocation of new root state. This should be done
6345 separately by use of scm_make_root.
6346 (scm_apply_with_dynamic_root): New function: Does what it
6347 sounds like. Needed when spawning threads.
6348
6349 * root.h: Added member last_debug_frame to root state.
6350 Added #include "libguile/debug.h"
6351
6352 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6353 arguments. The motivation is that code in root.c needs catch
6354 functionality, and we want to avoid code duplication.
6355 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6356 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6357 handlers that run without popping the stack into the dynwind
6358 chain.
6359
6360 * throw.h: Added prototypes for scm_catch_apply and
6361 scm_lazy_catch.
6362
6363 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6364
6365 * root.h (scm_root, scm_set_root): Decouple thread support details
6366 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6367 SCM_SET_THREAD_LOCAL_DATA.
6368
6369 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6370 and tortoise scanning loop.
6371
6372 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6373
6374 * Makefile.in: Rebuild dependencies.
6375
6376 * libguile.h: #include "libguile/print.h" before "smob.h", since
6377 the latter uses the print_state structure.
6378
6379 * throw.c (scm_ithrow): Use the correct variable when checking to
6380 see if a given element of scm_dynwinds is a valid catch.
6381
6382 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6383 structure, abort; don't just silently ignore the garbage.
6384
6385 * _scm.h: #include "print.h" here, since it seems to be used just
6386 about everywhere.
6387 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6388 strports.c, unif.h: Don't #include "print.h".
6389
6390 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6391
6392 * feature.h (scm_loc_features): Removed external declaration.
6393 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6394
6395 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6396
6397 * feature.c (scm_init_feature): Added threads feature (needs to be
6398 initialized here, since features doesn't exist when
6399 scm_init_threads is called).
6400
6401 * libguile.h: Added #include "libguile/../threads/threads.h".
6402 (This is a kludge to get thread support working. This should be
6403 fixed.)
6404
6405 * configure.in, acconfig.h: Added flags for thread support.
6406
6407 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6408 mit-pthreads.
6409
6410 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6411 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6412 root.c:mark_root.
6413
6414 * _scm.h: Added conditional #include "threads.h"
6415
6416 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6417 SCM_THREADS_SWITCHING_CODE.
6418
6419 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6420 allocate the basic dynamic root object.
6421 (scm_boot_guile): Added call to scm_init_root.
6422
6423 * root.c, root.h: Added root smob.
6424 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6425 functions: Implements dynamic roots mostly according to spec in
6426 SCM manual. Main difference is that the second argument is a
6427 throw handler rather than an error "thunk".
6428
6429 * root.h: Added declaration of scm_init_root.
6430
6431 * root.c: Added #include "genio.h", #include "smob.h", #include
6432 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6433 "eval.h"
6434 (scm_init_root): Added #include "root.x".
6435
6436 * throw.c: Added #include "stackchk.h"
6437 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6438 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6439 can be used in scm_call_with_new_root; Added reenabling of stack
6440 checking when catching a throw.
6441
6442 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6443
6444 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6445
6446 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6447 element is not found, as per R4RS.
6448
6449 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6450
6451 * list.c: Doc fixes throughout.
6452
6453 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6454
6455 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6456 declare the char * to be const. Avoids a warning in rgx.c.
6457
6458 * ports.h: spelling fix.
6459
6460 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6461 error messages.
6462
6463 * load.c (scm_sys_try_load_path): throw an error if file not found
6464 (like it says it in NEWS).
6465
6466 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6467
6468 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6469 PROPS slot to '(), not #f; it's an empty alist.
6470
6471 * throw.h, throw.c: Use SCM_P instead of #if hair.
6472
6473 Remove special support for uncaught throws; see throw.c for
6474 rationale.
6475 * throw.c (uncaught_throw): New function.
6476 (scm_ithrow): Call uncaught_throw if we don't find a throw
6477 target; don't mess with scm_bad_throw_vcell.
6478 (scm_bad_throw_vcell): Variable deleted.
6479 (scm_init_throw): Don't initialize it.
6480
6481 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6482 #t catches.
6483
6484 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6485
6486 * numbers.c (scm_istr2int): If the number is short (as most
6487 numbers are), just call scm_small_istr2int to deal with it.
6488 (scm_small_istr2int): New function, created by un-#ifdefing the
6489 non-bignum version of scm_istr2int and renaming it.
6490
6491 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6492
6493 * load.c (scm_sys_try_load): don't check whether value returned
6494 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6495 Change the Scheme name from %try-load to primitive-load.
6496
6497 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6498 Can avoid passing a message, allowing it to be derived in the
6499 error handler (e.g., if we want to throw to the key both from
6500 Scheme and C).
6501
6502 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6503
6504 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6505 references now have a new appearance which is more compact and
6506 also gives a clue about what the target of the reference is.
6507 By setting parameters in the print state, more fancy printing can
6508 be achieved. This is used by the (not yet commited) backtrace
6509 code.
6510
6511 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6512
6513 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6514 "print.h"
6515
6516 * print.c: Added #include "struct.h". Removed function
6517 scm_prlist.
6518
6519 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6520 scm_iprin1. Removed prototype for scm_prlist.
6521
6522 * arbiters.c (prinarb),
6523 async.c (print_async),
6524 debug.c (prindebugobj, prinmemoized),
6525 eval.c (prinprom, prinmacro),
6526 filesys.c (scm_fd_print, scm_dir_print),
6527 kw.c (print_kw),
6528 mallocs.c (prinmalloc),
6529 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6530 smob.h (scm_smobfuns),
6531 srcprop.c (prinsrcprops),
6532 throw.c (prinjb),
6533 unif.c, unif.h (scm_raprin1, rapr1),
6534 variable.c (prin_var): Changed argument `int writing' to
6535 `scm_print_state *pstate'.
6536
6537 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6538 that it will be called before scm_init_print.
6539
6540 * print.c (scm_prin1): Print states are now allocated when calling
6541 scm_prin1 and then passed around to all printing functions as an
6542 argument. A cache `print_state_pool' enables reuse of print
6543 states.
6544 (scm_make_print_state): New function.
6545 (scm_iprin1): Adaption to print states.
6546 (scm_iprlist): An initial "hare and tortoise" scan brings down
6547 time complexity to O (depth * N). (Better time complexity will be
6548 achieved when the printing code is completely rewritten.)
6549
6550 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6551
6552 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6553 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6554 it gets done whether or not the cache variable has a value.
6555
6556 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6557
6558 Distinguish #f and ().
6559 * __scm.h: #undef SICP.
6560 * pairs.h (SCM_EOL): Delete this definition, equating it with
6561 SCM_BOOL_F.
6562 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6563 the value it used to have. Doc fixes, too.
6564
6565 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6566
6567 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6568 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6569 Lord's implementation of structs, allowing for tail arrays as
6570 described in the manual. Also fixed some bugs. (Both the interface
6571 and the implementation should be improved.)
6572
6573 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6574
6575 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6576 People who whish to see the source can do `(print-enable 'source)'.
6577 Removed #ifdef DEBUG_EXTENSIONS.
6578
6579 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6580
6581 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6582 integer (assuming for now accepting an integer is a good thing).
6583
6584 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6585 %S will be used instead for write'ing arguments.
6586
6587 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6588 asserts. fix a few other asserts.
6589 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6590 scm_uniform_vector_ref, scm_array_set_x,
6591 scm_dimensions_to_unform_array): change args in
6592 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6593 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6594 scm_substring_fill_x): likewise.
6595 gsubr.c (scm_gsubr_apply): likewise.
6596 eval.c (SCM_APPLY): likewise.
6597
6598 * eval.c (4 places): replace scm_everr with lgh_error or
6599 scm_wrong_num_args.
6600
6601 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6602 scm_memory_error): new procedures.
6603 scm_everr: deleted. can use scm_wta, dropping first two args.
6604 scm_error: convert NULL subr to SCM_BOOL_F.
6605
6606 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6607 SCM_ARGERR.
6608
6609 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6610 of scm_wta.
6611
6612 * error.c, error.h: new error keys: scm_arg_type_key,
6613 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6614 scm_misc_error_key.
6615 scm_wta: reimplement using lgh_error instead of scm_everr.
6616
6617 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6618
6619 * gdbint.c: scm_lread now has one more argument.
6620
6621 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6622 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6623 loading source from non-file ports, which, e. g., happens when
6624 using the Emacs interface).
6625
6626 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6627 object.
6628
6629 * read.c: Added code for recording of positions of source code
6630 expressions; New functions: recsexpr, scm_lreadrecparen;
6631 _scm_make_srcprops --> scm_make_srcprops
6632 (scm_flush_ws): Removed updating of positions counters. This work
6633 is already done by scm_gen_getc
6634
6635 * read.h: Added prototype for scm_lreadrecparen
6636
6637 * print.c: Added #include "alist.h"
6638
6639 * eval.c: Added #include "hash.h"
6640
6641 * eq.c: Added #include "ramap.h"
6642
6643 * options.c: Documentation fixes.
6644
6645 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
6646 (scm_init_srcprop): Adjusted size of initial source-whash. Name
6647 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
6648 --> scm_make_srcprops
6649
6650 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
6651 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
6652 function calls in the definition of the whash access macros.
6653
6654 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
6655
6656 * init.c (scm_boot_guile): Add level of indirection to
6657 scm_boot_guile_1() to ensure that stack base pointer is properly
6658 initialized. There was no guarantee that variable i was the
6659 highest/lowest variable on stack (i.e. the call frame of
6660 scm_boot_guile was not completely protected from gc).
6661
6662 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
6663
6664 * ports.h (scm_port_table): put back file_name, it will be used to
6665 support debugging. Undo related changes in fports.c, ioext.c,
6666 ports.c, gc.c.
6667
6668 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6669
6670 * ports.h (scm_port_table): remove file_name member for now, it seems
6671 undesirable.
6672 * fports.c (scm_open_file): don't set file_name in PTAB.
6673 (prinfport): don't use file_name in PTAB.
6674 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
6675 * ports.c (scm_add_to_port_table): don't intialize file_name.
6676 (scm_port_file_name): remove for now.
6677 * gc.c (scm_gc_mark): don't mark PTAB file_name.
6678
6679 * fports.h (scm_mkfile): prototype deleted.
6680 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
6681
6682 * debug.c, unif.c: use scm_out_of_range instead of
6683 wta for range errors (ASSERT still needs work).
6684
6685 * error.c, error.h (scm_out_of_range): new procedure.
6686
6687 * error.c, error.h (scm_out_of_range_key): new key.
6688
6689 * posix.c (scm_sync): #else was missing.
6690
6691 * error.c, error.h: append _key to names scm_num_overflow and
6692 scm_system_error.
6693
6694 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
6695 of consing an empty list.
6696 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
6697 of macros, saves code and string space.
6698 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
6699 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
6700 lower case. Rename scm_syserror_m to scm_syserror_msg.
6701 error.h: prototypes for new procedures.
6702
6703 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
6704
6705 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
6706
6707 * error.c, error.h: setup scm_num_overflow key.
6708
6709 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
6710 Remove definition of SCM_OVSCM_FLOW.
6711
6712 * fports.c (scm_open_file): use SCM_SYSERROR_M.
6713
6714 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
6715 explicit message and args.
6716
6717 * error.c, error.h, __scm.h: change system_error_sym to
6718 scm_system_error.
6719
6720 * error.c (system_error_sym): remove leading %% from the Scheme name
6721 "%%system-error".
6722
6723 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
6724
6725 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6726
6727 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
6728 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
6729 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
6730 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
6731 renamed. (These were introduced by unsupervised name
6732 substitution.)
6733
6734 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6735
6736 * print.c: Added code for detection of circular references during
6737 printing. (init_ref_stack, grow_ref_stack): New functions. Added
6738 a hook for printing of closures (accessible via print options).
6739 This leads to a split of calls to scm_iprin1 into two classes:
6740 elementary print operations (e. g. the code which prints a smob)
6741 still use scm_iprin1 while top level calls (like scm_display) use
6742 scm_prin1. scm_prin1 begins by clearing the data structure used
6743 to record reference information.
6744
6745 * print.h: Added declarations of scm_prin1 and scm_prlist.
6746
6747 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
6748
6749 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
6750
6751 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
6752
6753 * error.c (err_head): scm_iprin1 --> scm_prin1
6754
6755 * debug.c: Adjusted header comment.
6756
6757 * tags.h: Typo.
6758
6759 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6760
6761 * strerror.c: Doc fix.
6762
6763 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6764
6765 * gdbint.c (gdb_read): Now possible to run during GC.
6766 (unmark_port, remark_port): New functions.
6767
6768 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
6769
6770 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
6771 of allocating a new string object. Also, increase size by
6772 the factor 2 instead of 1.5.
6773
6774 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
6775
6776 * __scm.h (SCM_P): Corrected to run under traditional C.
6777
6778 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
6779 removed.
6780
6781 * async.c: Calls to scm_sysintern corrected.
6782
6783 * async.h (scm_async_clock): Redundant declaration removed.
6784
6785 * continuations.c (scm_dynthrow): Redundant declaration removed.
6786
6787 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
6788 Definition typos corrected.
6789
6790 * debug.h: Missing declarations of functions in debug.c added
6791 (lots).
6792
6793 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
6794 Missing declarations to functions in eval.c added.
6795
6796 * filesys.c: Possibly uninitialized variable rv.
6797
6798 * gc.h (scm_object_addr, scm_unhash_name): Missing
6799 declarations of functions defined in gc.c added.
6800
6801 * genio.c: Possible typos str_data -> wstr_data. ???
6802
6803 * genio.c: Possibly unintended shadowing of local variable
6804 `int c' (gotos out of scope of inner `c'). ???
6805
6806 * init.c: Uninitialized `SCM last' may be used.
6807
6808 * ioext.h: (scm_sys_isatty_p): Typo.
6809
6810 * list.h (scm_list_head): Missing prototype for function in
6811 list.c added.
6812
6813 * numbers.c (scm_two_doubles): Changed from extern to static
6814 (is used only within numbers.c).
6815
6816 * numbers.h: Repeated declarations removed.
6817
6818 * ports.h (scm_close_all_ports_except): Declaration for the
6819 function defined in ports.c added.
6820
6821 * posix.h: Missing declarations added.
6822
6823 * procs.h (scm_make_subr_opt): Missing declaration added.
6824
6825 * socket.h (scm_sys_gethost): Missing declaration added.
6826
6827 * socket.h: Redundant declarations removed (they are in fdsocket.h).
6828
6829 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
6830 Missing declarations added.
6831
6832 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
6833
6834 * struct.c: Uninitialized variable `SCM answer' may be used.
6835
6836 * unif.c (l2ra): Declaration prototype.
6837
6838 * unif.c (scm_array_equal_p): Dummy definition removed (it is
6839 defined in ramap.c).
6840
6841 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
6842 Redundant declarations removed (they are in ramap.h).
6843
6844 * variable.h (scm_make_udvariable,
6845 scm_make_undefined_variable): Declaration corrected to
6846 correspond variable.c.
6847
6848 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
6849 Missing declarations added.
6850
6851 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
6852
6853 * Makefile.in (distclean): Don't forget to delete fd.h.
6854
6855 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6856
6857 * fd.h.in, tags.h: Trivial cleanups.
6858
6859 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
6860 marksweep.h just declared functions from gc.c.
6861 * gc.h, libguile.h: Don't #include "marksweep.h".
6862 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
6863 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
6864 dependencies updated.
6865
6866 * libguile.h: Don't #include "files.h"; it's been deleted.
6867
6868 * files.c (scm_sys_delete_file): Moved to filesys.c.
6869 File is now empty; deleted.
6870 * files.h: Deleted.
6871 * filesys.c: scm_sys_delete_file is now here. Remove
6872 #if's; they seem to rely on remnants of an old portability
6873 regimen. If the problems come up again, solve them properly,
6874 using autoconf. Specifically: Don't test M_SYSV, and #define
6875 remove to be unlink if it's #defined; don't use remove just
6876 because HAVE_STDC_HEADERS is #defined.
6877 * filesys.h: Add declarations for scm_sys_delete_file.
6878 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
6879 files.o, files.h, files.c, and files.x.
6880 * init.c: Don't #include "files.h", and don't call scm_init_files.
6881
6882 Use SCM_P instead of PROTO; the latter intrudes on the user's
6883 namespace.
6884 * params.h: Deleted; definition of SCM_P moved to...
6885 * __scm.h: ... here, where it replaces PROTO macro.
6886 * libguile.h, smob.h: Don't #include "params.h".
6887 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
6888 smob.h: Fix prototypes accordingly.
6889 * Makefile.in: Update dependencies.
6890 (inner_h_files): Remove params.h.
6891
6892 * gc.c: #include "gc.h"; every module should include its header,
6893 to let the compiler cross-check the declarations against the
6894 definitions.
6895
6896 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
6897 simpos.h: #include "libguile/__scm.h".
6898
6899 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
6900
6901 * init.c: Don't forget to #include smob.h and init.h.
6902 * Makefile.in: Dependencies updated.
6903
6904 * smob.h: Use PROTO instead of #if __STDC__.
6905
6906 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
6907
6908 * __scm.h: Doc fixes.
6909
6910 * __scm.h, libguile.h: Use "quotes" in the #includes, not
6911 <angles>; this allows `make depends' to work properly.
6912
6913 * libguile.h: #include smob.h and pairs.h before the others; they
6914 define typedefs used by other headers.
6915
6916 C files should #include only the header files they need, not
6917 libguile.h (which #includes all the header files); the pointless
6918 recompilation was wasting my time.
6919 * Makefile.in (all .o dependency lists): Regenerated.
6920 * libguile.h: Don't try to get a definition for size_t here...
6921 * __scm.h: Do it here.
6922 * _scm.h: Since this is the internal libguile header, put things
6923 here that all (or a majority) of the libguile files will want.
6924 Don't #include <libguile.h> here; that generates dependencies on
6925 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
6926 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
6927 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

6960 * hashtab.c: Get "hashtab.h", "eval.h", "hash.h", "alist.h".
6961 * init.c: Get everyone who has an scm_init_mumble function:
6962 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
6963 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

7012 * struct.c: Get "struct.h", "chars.h".
7013 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",
7014 "variable.h", "eval.h", "chars.h".
7015 * tag.c: Get "tag.h", "struct.h", "chars.h".

7023 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7024 * weaks.c: Get "weaks.h".
7025
7026 * stackchk.h: #include "libguile/debug.h",
7027
7028 * print.h, read.h: #include "options.h", since everyone who uses
7029 either of these files will need that.
7030
7031 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7032 anyone who uses this file will need them to define the smob
7033 printing functions. Also, get markers.h, since people will need
7034 to #define the mark functions.
7035
7036 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7037 * ports.h: ... to here.
7038
7039 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7040 don't rely on archaic C default type rules.
7041
7042 * fports.h: #include "libguile/ports.h", since you need that in
7043 order to parse this.
7044
7045 * genio.h: #include "libguile/print.h", because you need that to
7046 parse this; don't bother #including "ports.h", since print.h gets
7047 that.
7048
7049 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7050
7051 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7052 this; it's now a reference to an element of *scm_root.
7053
7054 * debug.h: Don't #include "options.h"; the compiler won't be able
7055 to find that once the headers are installed; instead, #include
7056 "libguile/options.h".
7057 * gc.h: Same, with marksweep.h.
7058 * mbstrings.h: Same, with symbols.h.
7059 * scmhob.h: Same, with _scm.h.
7060 * smob.h: Same, with params.h.
7061
7062 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7063 C files; there's no need for this, and it forces recompilations
7064 unnecessarily.
7065
7066 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7067
7068 * error.c (scm_error): declare scm_error_callback.
7069
7070 * error.h: prototype for scm_error_callback.
7071
7072 * __scm.h: define lgh_error.
7073 (SCM_SYSERROR): redefine using lgh_error.
7074
7075 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7076
7077 * error.c (scm_error): new procedure.
7078
7079 * error.h: prototype for scm_error.
7080
7081 * Makefile.in (install): install scmconfig.h from the current
7082 directory, not $(srcdir).
7083
7084 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7085
7086 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7087 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7088 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7089 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7090 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7091 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7092 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7093 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7094 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7095 vports.h, weaks.h: #include "libguile/__scm.h", not
7096 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7097 dependencies are within libguile properly.
7098
7099 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7100
7101 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7102 when scmconfig.h doesn't exist.
7103
7104 * load.c (scm_sys_try_load): Correct spelling.
7105
7106 * feature.c (scm_loc_features): Make this static.
7107
7108 * Makefile.in (libpath.h): Omit trailing slash from path. We
7109 shouldn't require it of users, so why put it here?
7110
7111 Move code to initialize and search %load-path from ice-9 to C
7112 code, so we can use the load-path to find the ice-9 boot code;
7113 this makes it easier to run Guile without installing it. See
7114 corresponding changes in guile/Makefile.in.
7115 * feature.c: Move stuff concerned with the load path to load.c.
7116 (scm_compiled_library_path): Deleted.
7117 Don't #include libpath.h here.
7118 * feature.h: Don't mention scm_compiled_library_path.
7119 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7120 <sys/stat.h>, and <unistd.h> (if present).
7121 (R_OK): #define if the system hasn't deigned to.
7122 (scm_loc_load_path): New variable.
7123 (scm_init_load_path, scm_sys_search_load_path,
7124 scm_sys_try_load_path): New functions.
7125 (scm_init_load): Initialize scm_loc_load_path to point to the
7126 value cell of the Scheme %load-path variable.
7127 * load.h: Add declarations for scm_sys_search_load_path,
7128 scm_sys_try_load_path.
7129 * init.c: Call scm_init_load_path.
7130 * Makefile.in (feature.o, load.o): Dependencies updated.
7131
7132 * load.c, load.h: Rewrite using PROTO macro.
7133
7134 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7135
7136 * gc.c (scm_cellp): New function: C predicate to determine if an
7137 SCM value can be regarded as a pointer to a cell on the heap.
7138
7139 * gc.h: Added declaration of scm_cellp.
7140
7141 * gdb_interface.h: New file: The GDB interface header from the GDB
7142 distribution.
7143
7144 * gdbint.c: New file: GDB interface.
7145
7146 * gdbint.h: New file: GDB interface.
7147
7148 * libguile.h: Added #include <libguile/gdbint.h>.
7149
7150 * init.c (scm_boot_guile): Added scm_init_gdbint.
7151
7152 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7153 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7154 found if object files and source are kept separate).
7155
7156 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7157
7158 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7159
7160 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7161
7162 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7163 TK_SRC_DIR; they're not relevant any more.
7164
7165 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7166 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7167
7168 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7169
7170 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7171 search path, so we can find the <libguile/MUMBLE.h> headers.
7172
7173 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7174
7175 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7176 implicit in the .c.o rule.
7177 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7178 $(CC) already.
7179
7180 Put the library path in a header file, instead of passing it on
7181 the command line in every compilation.
7182 * Makefile.in (libpath.h): New target.
7183 (feature.o): Depend on libpath.h.
7184 (clean): Delete libpath.h.
7185 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7186 * feature.c: ... #include "libpath.h" here.
7187 * .cvsignore: Ignore libpath.h.
7188
7189 Don't install the unwashed masses of Guile header files in the
7190 main #include path; put most of them in a subdirectory called
7191 'libguile'. This avoids naming conflicts between Guile header
7192 files and system header files (of which there were a few).
7193 * Makefile.in (pkgincludedir): Deleted.
7194 (innerincludedir): New variable; this and $(includedir) are enough.
7195 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7196 (installed_h_files): Divide this up. Now this variable lists
7197 those header files which should go into $(includedir) (i.e. appear
7198 directly in the #include path), and ...
7199 (inner_h_files): ... this new variable says which files appear in
7200 a subdirectory, and are referred to as <libguile/mumble.h>.
7201 (h_files): List them both.
7202 (install): Create innerincludedir, not pkgincludedir. Put
7203 the installed_h_files and inner_h_files in their proper places.
7204 (uninstall): Corresponding changes.
7205 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7206 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7207 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7208 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7209 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7210 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7211 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7212 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7213 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7214 vports.h, weaks.h: Find __scm.h in its new location.
7215 * __scm.h: Find scmconfig.h and tags.h in their new locations
7216 (they're both "inner" files).
7217
7218 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7219
7220 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7221
7222 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7223
7224 * posix.c: Doc fixes.
7225
7226 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7227
7228 * socket.c: Don't include a prototype for inet_aton; just use a
7229 K&R style declaration, to avoid warnings but minimize the chance
7230 of conflicts with the system.
7231
7232 On NextStep, <utime.h> doesn't define struct utime, unless we
7233 #define _POSIX_SOURCE before #including it.
7234 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7235 * acconfig.h: New comment text for above CPP symbol.
7236 * configure.in: Call it.
7237 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7238
7239 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7240 in the list.
7241 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7242 testing for __EMX__.
7243
7244 * posix.c: #include <libc.h>, if it exists.
7245
7246 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7247 don't even know if the latter exists.
7248
7249 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7250 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7251 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7252
7253 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7254 header files don't.
7255 (scm_init_posix): Use them when initializing the Scheme constants
7256 of the same name.
7257
7258 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7259
7260 * Makefile.in (libdir, includedir, bindir): Use the
7261 autoconf-supplied values, instead of deriving them ourselves.
7262 (pkgincludedir, datadir, pkgdatadir): New variables.
7263 (install, uninstall): Put the header files in a special
7264 subdirectory, not in the main search path.
7265
7266 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7267 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7268
7269 * Makefile.in (IMPLPATH): Deleted; never used.
7270
7271 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7272 on the Tcl/Tk source any more.
7273 (INCLUDE_CFLAGS): Remove references to the above.
7274
7275 * Makefile.in (version.o): Corrected dependencies.
7276
7277 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7278
7279 * libguile.h: #include "version.h"
7280
7281 * init.c (scm_boot_guile): Call scm_init_version.
7282 * gscm.c (gscm_run_scm): Call scm_init_version.
7283
7284 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7285 GUILE_VERSION): AC_DEFINE these.
7286 (acconfig.h): #undef the above symbols.
7287
7288 * Makefile.in (libobjs): Add version.o.
7289 (installed_h_files): Add version.h.
7290 (c_files): Add version.c.
7291 (gen_c_files): Add version.x.
7292 (version.o): New rule.
7293 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7294 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7295 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7296 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
7297 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
7298 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
7299 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
7300 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
7301 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
7302 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7303 weaks.o): Add version.h to dependency lists.
7304 (markers.o): Remove duplicate rule.
7305
7306 * version.h: New file.
7307
7308 * version.c: New file.
7309
7310 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7311
7312 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7313 array; use it appropriately. Since GCC is quite happy to
7314 subscript functions, it never warned us about this; we should use
7315 -Wpointer-arith in the future. I guess we never tested
7316 case-insensitivity.
7317
7318 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7319
7320 * socket.c: Doc and copyright fixes.
7321
7322 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7323
7324 * debug.c: Fixed and improved gdb support.
7325
7326 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7327
7328 * socket.c: Added declaration of inet_aton to avoid compiler
7329 warning. (Hope this solution is correct.)
7330
7331 * stime.c: Added declaration of ftime. (This is missing in
7332 Solaris 2 headers.)
7333
7334 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7335
7336 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7337
7338 * Makefile.in (c_files): add strerror.c.
7339
7340 * strerror.c: new file from Emacs' sysdep.c.
7341 maybe configure should also check for sys_errlist.
7342
7343 * configure.in (AC_REPLACE_FUNCS): add strerror.
7344
7345 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7346
7347 * debug.c (scm_init_debug): Added initialization for
7348 scm_evaluator_traps.
7349
7350 * debug.h, debug.c: Various name changes.
7351 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7352 "debug-options-interface". See commentary in options.c.
7353
7354 * options.h, options.c: Options now have documentation strings.
7355 Also added a long explanatory commentary.
7356
7357 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7358 run-time options.
7359
7360 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7361 last_debug_info_frame is now updated in all cases.
7362
7363 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7364 checking.
7365
7366 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7367
7368 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7369 Added option STACK_CHECKING.
7370
7371 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7372
7373 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7374
7375 * __scm.h: Removed symbols for debugging support.
7376
7377 * acconfig.h: Added symbols for debugging support.
7378
7379 * configure.in: Added user option for debugging support.
7380 --enable-debug will include the debugging code into libguile.a.
7381
7382 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7383 scm_relocate_chunk_to_heap.
7384
7385 * debug.c: New file: low-level debugging support. It also
7386 includes support for debugging with gdb. (The extensions to gdb
7387 are written by Per Bothner at Cygnus.)
7388
7389 * debug.h: New file: low-level debugging support.
7390
7391 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7392 argument pairs. Extensive modifications to the debugging
7393 evaluator. Added "SECTION:" commentaries to clarify what happens
7394 when, during double compilation. Renamed EVALIMP --> EVALIM.
7395 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7396 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7397 the beginning of the file. New procedure: scm_unmemocopy.
7398 Added some global state variables needed by the debugging
7399 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7400 check_entry, check_apply, check_exit, debug_options and
7401 evaluator_traps. New acro: undefine.
7402
7403 * eval.h: Renamed EVAL --> XEVAL.
7404
7405 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7406 --> scm_make_weak_key_hash_table.
7407
7408 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7409 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7410
7411 * libguile.h: Conditionally include debug.h
7412
7413 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7414 scm_object_properties shouldn't return handle. `handle' now gets
7415 initialized in scm_set_object_properties_x. scm_object_properties
7416 doesn't any longer create an entry in scm_object_whash.
7417
7418 * options.c: New file: handling of run time options.
7419
7420 * options.h: New file: handling of run time options.
7421
7422 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7423
7424 * print.c: New procedure: scm_print_options
7425
7426 * print.h: Defines for print options.
7427
7428 * read.c: New procedure: scm_read_options
7429
7430 * read.h: Defines for reader options.
7431
7432 * root.h: Added scm_source_whash among scm_sys_protects.
7433
7434 * srcprop.c: New file: source properties.
7435
7436 * srcprop.h: New file: source properties.
7437
7438 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7439 (Bug found by A. Green.)
7440
7441 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7442
7443 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7444
7445 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7446
7447 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7448
7449 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7450 and should be called by the final client.
7451
7452 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7453
7454 * gc.h: Use the PROTO macro when declaring functions.
7455 * gc.c: Use the PROTO macro when declaring static functions.
7456 Remove the CPP hair around function definitions.
7457
7458 * gc.c (scm_init_storage): Initialize scm_asyncs.
7459
7460 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7461 preprocessor symbol; "__scm.h" is where it might get #defined.
7462 * __scm.h: Similar: #include <scmconfig.h> before testing
7463 HAVE_LIMITS_H.
7464
7465 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7466
7467 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7468
7469 * init.c (scm_boot_guile): Add init_func argument; call
7470 (*init_func) instead of calling scm_appinit; it's ucky to
7471 hard-code names for the user's procedures.
7472 * init.h (scm_boot_guile): Adjust declaration.
7473
7474 * __scm.h (PROTO): New macro, for declaring functions with
7475 prototypes.
7476
7477 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7478 eliminate all the __STDC__ conditionals.
7479 (scm_boot_guile): Add declaration.
7480 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7481 Remove __STDC__ conditionals around function definitions; the
7482 declarations in init.h will provide the same information, more
7483 usefully.
7484
7485 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7486 complain about it in the error message; the error message is
7487 adequate without that note, and there's nothing the user can do
7488 about it.
7489
7490 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7491
7492 * Makefile.in (ancillary): Drop def.sed.
7493
7494 * posix.c (scm_init_posix): Use numeric values, rather than
7495 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7496 F_OK. The symbols aren't available on some systems, and I'm
7497 pretty sure their values are fixed by common widespread practice.
7498 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7499
7500 More functions unavailable on some systems.
7501 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7502 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7503 check for.
7504 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7505 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7506 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7507 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7508 stub that signals an error as the #else.
7509
7510 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7511
7512 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
7513
7514 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
7515
7516 * unif.c: include ramap.h.
7517
7518 * read.c (endif): case_insensative_p renamed case_insensitive_p.
7519
7520 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
7521
7522 * ports.c: include sys/ioctl.h.
7523
7524 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
7525
7526 * configure.in: check for sys/ioctl.h.
7527
7528 * ports.c: include <malloc.h> not "malloc.h".
7529
7530 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7531
7532 * fports.c: remove ttyname and tmpnam declarations.
7533
7534 * posix.c: fewer ttyname declarations.
7535
7536 * fports.c: include <string.h> not "string.h".
7537
7538 * init.c, ioext.c: include string.h and unistd.h.
7539
7540 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7541
7542 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
7543 genio.c, simpos.c, vports.c: include string.h.
7544
7545 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
7546
7547 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
7548 scm_sizet to int.
7549 (scm_addr_buffer_size): change type from scm_sizet to int.
7550 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
7551 from scm_sizet to int.
7552
7553 * error.c: include unistd.h.
7554
7555 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
7556 defined.
7557
7558 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
7559
7560 * __scm.hd, def.sed: deleted.
7561
7562 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
7563
7564 Changes for NeXT, suggested by Robert Brown.
7565 * configure.in: Call AC_TYPE_MODE_T.
7566 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
7567 NeXT. Put header file list in alphabetical order.
7568 * configure, scmconfig.h.in: Regenerated.
7569 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
7570
7571 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
7572 for strerror.
7573
7574 * acconfig.h: New file, providing documentation for the CPP
7575 symbols defined in configure.in
7576 * acconfig-1.5.h: Removed; superceded by the above.
7577
7578 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
7579
7580 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
7581
7582 * fports.c (scm_open_file): don't return #f, throw error.
7583
7584 * ioext.c (fileno): renamed from %fileno.
7585 (soft-fileno): deleted.
7586
7587 * ports.c (scm_port_revealed): don't need to check for -1 from
7588 scm_revealed_count.
7589 (scm_set_port_revealed_x): return unspecified, not #f.
7590
7591 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
7592
7593 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
7594
7595 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
7596
7597 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
7598
7599 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7600
7601 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
7602 This is necessary on Ultrix, and doesn't hurt portability.
7603
7604 * Makefile.in (dist-dir): New target, implementing a new dist system.
7605 (installed_h_files): Put in alphabetical order.
7606 Remove duplicate entries for markers.h and unif.h.
7607 (c_files): Remove duplicate entries for markers.c.
7608 (ancillary): Renamed from anillery; all uses changed. Remove
7609 PLUGIN; it's a directory, and needs special treatment in dist-dir.
7610 Remove all the ../doc/* files; doc/Makefile.in handles that.
7611
7612 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
7613
7614 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
7615 every if must have an else, or else the whole command has a
7616 non-zero exit code whenever the if's condition is false.
7617
7618 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
7619
7620 * posix.c: include string.h.
7621
7622 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7623
7624 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must

7863 functions. hash, hashq, hashv, hashx.
7864

7901 set the multi_byte flag correctly in symbols. This is wrong.
7902 intern_obbary_soft and msymbolize should take an extra parameter.
7903 Also, weird multibyte symbols don't print correctly.
7904 The weird symbol syntax is also a bit bogus (emacs doesn't quite
7905 cope).
7906

7908
7909 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
