1 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * eval.c (scm_m_expand_body): Use scm_cons_source.
5 * struct.c (scm_print_struct): Use vtable name.
7 * print.c (scm_init_print): Set name of print state type.
9 * stacks.c (scm_init_stacks): Set name of stack type.
11 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
13 * eval.c (SCM_CEVAL): Removed old implementation of internal
16 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
18 * debug.c, debug.h (scm_reverse_lookup): Added.
19 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
20 internal procedure definitions; Don't use scm_i_inner_name.
22 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
25 * eval.h: Added prototypes for multi language support functions.
27 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
28 improper lists in the low-level representation, since that will
29 cause a begin to be prepended at macro expansion.
31 * eval.c (scm_cons_source): Version of cons which copies source
32 properties from an existing cell.
33 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
35 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
36 procedure source before calling scm_unmemocopy instead of faking
39 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
41 Ported `internal defines' fix from SCM. Original ChangeLog entry:
43 1998-07-09 Radey Shouman <radey@colorage.com>
45 * eval.c (ceval_1): Modifications to allow rewriting of interal
46 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
47 body of which it is the CAR is macro expanded by m_expand_body,
48 which rewrites internal DEFINE.
50 (m_expand_body): Added.
52 (m_macroexp1): Added argument to control error checking:
53 m_expand_body may speculatively expand forms in the wrong
54 environments. Made argument number checks conditional on
57 (m_body): Added, error checks bodies and inserts the ISYM tokens.
59 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
62 (m_cond): (m_case): (m_quote): Modified to avoid destructively
63 changing their argument forms. Since m_expand_body
64 speculatively macro expands forms the process must be
67 (m_ident_eqp): Fixed to use proper environment.
69 (renamed_ident): Added DEFER_INTS_EGC.
71 Added prototypes for static functions.
77 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
78 is false, do not produce an error for unbound variables, return a
79 pointer to cell_undef instead.
81 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
85 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
86 destructively changing their argument forms. Since m_expand_body
87 speculatively macro expands forms the process must be reversible.
89 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
90 SCM_IM_LET introduced by named lets.
92 (scm_m_letstar): Use scm_m_body instead of bodycheck.
94 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
95 scm_letrec. scm_letrec1 does not check for a null binding and
96 takes an additional argument to specify the ISYM of the body. Use
97 scm_m_body instead of bodycheck.
99 (scm_m_let): Use scm_m_body instead of bodycheck.
101 (scm_m_expand_body, scm_macroexp): New.
103 (unmemocopy): Account for ISYMs introduced by scm_m_body.
105 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
106 check=1. Throw error for internal defined that have not been
107 rewritten by scm_m_expand_body.
109 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
110 Removed prototype for SCM_APPLY.
112 * tags.h: Added extern declaration of scm_isymnames.
114 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
116 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
118 * lang.c: New file: Beginning of multi-language support.
120 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
122 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
123 (scm_dynamic_wind): Added argument checking for the after guard so
124 that we don't add garbage on the dynwind chain.
125 (scm_swap_bindings): Added.
127 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
128 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
129 (scm_isymnames): New isyms for multi-language support.
131 * eval.c (scm_nil, scm_t): New symbols.
132 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
133 forms for multi-language support.
135 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
137 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
139 Renamed functions in the random function library interface
140 from scm_i_XXX --> scm_c_XXX.
142 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
144 * ports.c (scm_putc): fix line-buffering.
146 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
148 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
149 scm_set_ptob_XXX --> scm_set_port_XXX.
151 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
153 * ports.c, ports.h (scm_make_port_type): New interface for
154 creation of port types (replaces scm_newptob). Just as for the
155 smobs, we need to separate the internal representation of smob
156 types from the interface, so that we easily can add new fields and
157 rearrange things without caring about backward compatibility.
158 This change was forced by the need in GOOPS to create classes
159 representing port types.
160 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
161 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

167 (scm_prinport): Removed.
168 (scm_port_print): Added.
169 (scm_print_port_mode): Added.
170 (void_port_ptob, print_void_port, close_void_port, noop0):
171 Removed. Removed #include "genio.h" Added #include "objects.h",
174 * fports.c (prinfport): Moved code from ports.c.
176 (scm_fptob): Removed. Instead use new interface.
177 (scm_make_fptob): Added. (Need to create basic ports in a
178 specific order in ports.c.)
180 * strports.c (scm_stptob, prinstpt, noop0): Removed
181 (scm_make_stptob): Added.
183 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
184 (scm_make_sfport): Added.
186 * filesys.c (scm_dir_print): Don't use the port printing code.
187 Instead provide specific directory printer.
189 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
191 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
194 * smob.c (scm_smob_print): Handle non-existing type name nicely.
195 Removed #include "genio.h"
197 * objects.c (scm_make_port_classes): New function ptr.
199 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
201 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
203 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
204 allow the 1st argument to be a fdes or filename as well as a
205 port (as in the filesys.c version).
207 * filesys.c (scm_truncate_file): removed.
209 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
211 * readline.c, readline.h: Removed.
213 * objects.c, objects.h (scm_port_class): Added.
214 (scm_class_of): Look up port class in scm_port_class.
215 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
216 SCM_INOUT_PCLASS_INDEX): Added.
219 * Makefile.am: Removed genio.c, genio.x.
223 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
225 * init.c: Make sure that scm_post_boot_init_modules is called only
226 once. (Important when using a dumped image.; Thanks to Bernard
229 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
231 * guardians.c (scm_guardian_zombify): Separate scanning for
232 zombies from marking the pairs of the free list.
234 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
235 use the macros. (Thanks to Michael Livshin.)
237 * eval.c (scm_m_lambda): Let bodycheck check the body of the
238 lambda. Let your sins be purified by the blood of the lambda.
239 (Thanks to Eric Hanchrow.)
241 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
242 (Thanks to Valdis Kletnieks.)
244 Fixes for EMX from Mikael Ståldal.
246 * filesys.c: #include <io.h>, if we have it.
247 * scmconfig.h.in: Regenerated.
249 * stime.c (ftime): Delete declaration for this function --- let
250 the system supply it.
252 Cleanups from John Bley.
254 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
256 * gsubr.c: Don't include "gsubr.h" twice.
258 Cleanups for compilation on Irix 6, from David Kaelbling.
260 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
261 regex_t pointer. This is what the callers have, mostly.
262 (scm_regexp_exec): Don't forget to pass the `rx' argument to
263 scm_regexp_error_msg.
265 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
266 int. That way, if we get a warning on this line, it's more likely
267 that we're really missing bits we care about.
269 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
272 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
273 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
274 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
275 cast at all is more appropriate in every case. At the moment, we
276 assume everywhere that SCM is an integral type anyway.
278 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
280 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
281 read_pos after scm_fill_buffer.
283 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
286 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
287 fports.c (fport_fill_buffer): implement the interface change.
289 * ports.c (scm_fill_buffer): interface change: no longer increments
290 read_pos past the character that's returned. it seems clearer to
291 leave it to the caller to decide what to do (thanks Jim).
293 * vports.c (sf_fill_buffer): put the read char into the buffer
294 as well as returning it.
296 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

310 * ports.c (scm_ftruncate): throw error if offset works out negative.
312 * strports.c (st_flush): increase string size in blocks of
313 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
314 it's greater and reset read_buf_size.
315 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
316 to be maintained for output ports too (it holds the written
317 part of the string, while write_buf may have unwritten buffer
319 (st_truncate): rewritten.
320 (top of file): added a few notes.
322 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
324 Patch from Greg Badros:
325 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
326 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
327 (function pointer) argument to scm_make_gsubr and scm_make_subr
328 calls. This avoids warnings in C++ programs using guile-snarf.
330 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
332 * strports.c (st_grow_port): set pt->read_pos. set
333 pt->read_buf_size one less than pt->write_buf_size if there's
334 an unwritten char at the end of the string. similarly for
336 (st_resize_port): renamed from st_grow_port.
337 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
338 seek from read_end instead of write_end for SEEK_END.
339 (st_ftruncate): calculate current length using readbuf, not write

351 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
353 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

456 * struct.c, struct.h:
458 In order to support different kinds of deallocation, a destructor
459 slot has been added to struct vtables. This allows for structs
460 containing pointers to other memory blocks.
462 (scm_struct_i_free): New hidden struct slot. Holds destructor for
463 instances to this vtable.
464 (scm_struct_free_0): New destructor: Doesn't deallocate data.

572 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
573 sbd_time. (Thanks to Eric Hanchrow.)
575 Fix from Ken Raeburn <raeburn@raeburn.org>:
576 * weaks.c (scm_make_weak_vector): Add another extra slot before
577 vector contents, to be used only during garbage collection.
578 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
579 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
581 (scm_weak_size, scm_n_weak): Deleted.
582 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
583 vectors without allocating new storage during GC, using
584 scm_weak_vectors as the head of the chain.
585 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
586 instead of stepping through an array.
587 (scm_gc_sweep): Update offset used to find start of weak vector to
589 (scm_init_storage): Set scm_weak_vectors to EOL.
591 Fix from Ken Raeburn <raeburn@raeburn.org>:
592 * gc.c (already_in_gc): New variable.
593 (scm_igc): Set and clear already_in_gc; abort if it's set at
596 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
598 Fix from Gary Houston:
599 * fports.c (local_seek): Signal an error if the seek fails.
600 * ports.c (scm_lseek): Don't check return value of port's seek
601 function; it's its job to signal an error if there's a problem.
603 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
605 * strports.c (scm_call_with_output_string): Don't include the
606 extra character at the end of the string in the result.
608 * ioext.c (scm_read_line): Switch to reading properly.
610 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
611 scmsigs.c, strports.c, vports.c: Install the sources which
612 actually correspond to the changes described below. I got the
613 ChangeLog entries and the patch from two different places...
615 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
617 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
618 it shows up as terrible performance, as we GC constantly.
620 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
621 newline. A bit faster, and definitely hairier.
622 (scm_read_line): Count newlines here instead.
624 * strings.c (scm_take_str): New function.
625 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
626 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
627 scm_take_str, to avoid copying the string.
629 Add some simple-minded support for line buffered ports.
630 * ports.h (SCM_BUFLINE): New flag for ports.
631 * init.c (scm_init_standard_ports): Request line-buffering on
632 the standard output port.
633 * * ports.c (scm_mode_bits): Recognize 'l' as a request for line
635 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
636 and there's a newline to be written, flush the port.
638 Gary Houston's open-buffer port patches:
640 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
642 * ports.c: (scm_lseek): clear buffers even if just reading current
645 * fports.c (local_fclose): call local_fflush unconditionally.
646 (various): don't use the scm_must... memory procs.
648 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
650 * ports.h (scm_port): make read_pos a pointer to const.
651 strports.c: take care of rw_active and rw_randow.
652 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
653 strports.c (scm_mkstrport): check that pos is reasonable.
654 ioext.c (scm_ftell, scm_fseek): use lseek.
655 (SCM_CLEAR_BUFFERS): macro deleted.
656 ioext.c (redirect_port: use ptob fflush, read_flush.
657 ports.h (scm_ptobfuns): add ftruncate.
658 ports.c (scm_newptob): set ftruncate.
660 * ports.c (scm_ftruncate): new procedure.

662 strports.c (st_seek, st_grow_port): new procs.
663 fports.h (scm_port): change size types from int to off_t.
664 ports.c (scm_init_ports): initialise the seek symbols here
665 instead of in ioext.c.
666 strports.c (scm_call_with_output_string): start with an empty
667 string, so seek and ftruncate can be used.
669 gdbint.c: adjust string port usage.
671 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
673 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
674 equivalent to fflush for the read buffer.
675 * ports.c (scm_newptob): set read_flush.
676 ports.c (void_port_ptob): set read_flush.
677 fports.c (local_read_flush): new proc. add to ptob.
678 strport.c (st_read_flush): likewise.
679 vport.c (sf_read_flush): likewise.
680 fports.h (struct scm_fport): remove random member. there's nothing
681 left but fdes. leaving it as a struct to allow for future changes.
682 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
683 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
684 ptob proc if the read buffer is filled.
686 1999-04-23 Gary Houston <ghouston@easynet.co.uk>

689 reading and writing members with rw_active member.
690 SCM_PORT_READ/SCM_PORT_WRITE: new values.
692 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
694 * ports.h (struct scm_port_table): add writing and reading members
695 to replace write_needs_seek: it isn't good enough for non-fports.
696 ports.c, ioext.c, fports.c: corresponding changes.
697 (struct scm_port_table): give it a typedef and rename to scm_port.
698 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
699 corresponding changes.
701 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
703 * ports.c (scm_newptob): bugfix: set seek member.
704 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
705 and generalised to all port types.
707 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
709 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
710 signals (it was only being done for handlers installed from Scheme).
711 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
712 waiting for input caused an EINTR error from read.
714 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
716 * ports.h (struct scm_port_table): make all the char members
717 unsigned, so they convert to int without becoming negative if large.
719 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
721 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
722 with threads enabled. rename this procedure to
723 fport_wait_for_input and take a port instead of a fdes.
724 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
726 * readline.c (scm_readline): Applied a patch from Greg Harvey to
727 get readline support working again: use fdopen to get FILE objects.
729 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
731 * gc.c (scm_init_storage): install an atexit proc to flush the
733 (cleanup): the new proc. it sets a global variable which can be
734 checked by the ptob flush procs to avoid trying to throw
735 exceptions during exit. not very pleasant but it seems more reliable.
736 * fports.c (local_fflush): check terminating variable and if set
737 don't throw exception.
738 * CHECKME: that the atexit proc is installed if unexec used.
740 * throw.c (scm_handle_by_message): don't flush all ports here.
741 it still causes bus errors.
743 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
746 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
748 * ports.c (scm_char_ready_p): check the port buffer and call the
749 ptob entry if needed.
751 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
752 ptob initialisers. use it in char-ready
754 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
756 * vports.c (sfflush): modified to write a char (since softports
757 currently use shortbuf.)
759 * fports.c (scm_standard_stream_to_port): moved to init.c and
762 * init.c (scm_init_standard_ports): make stdout and stderr
763 unbuffered if connected to a terminal. with stdio they
764 were line-buffered by default.
766 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
769 * ports.h (scm_ptobfuns): change fflush return to void.
770 change flush proc definitions.
772 * strports.c (scm_call_with_output_string): get size from
773 buffer instead of port stream.
774 (st_flush): new proc.
776 * ports.h (struct scm_port_table): added write_end member,
777 as an optimisation. set it where write_buf_size is set.
779 * ports.h (struct scm_port_table): change stream from void *
780 back to SCM. SCM presumably must be large enough to hold a
781 pointer (and probably vice versa but who knows.)
782 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
784 (scm_puts): rewritten
785 * fports.c (local_ffwrite, local_fputs): removed.
786 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

797 * ports.h (scm_ptobfuns): add seek function pointer.
798 * fports.c: set it to local_seek, new procedure.
801 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
802 use ptob for seek. take ptob instead of fport arg.
804 * ports.h (struct scm_port_table): new member write_needs_seek,
805 replaces reading member in fport struct.
807 * vports.c (sfgetc): store the getted char into the buffer.
808 rename to sf_fill_buffer and install it for fill-buffer in ptob.
809 the Scheme interface is still a procedure that gets a char.
810 (scm_make_soft_port): set up the port buffer (shortbuf).
812 * fports.c (local_fgetc, local_fgets): deleted.
813 * strports.c (stgetc): likewise.
814 * ports.c: scm_generic_fgets: likewise.
816 * ports.h (scm_ptobfuns): add fill_buffer.
817 * ports.c (scm_newptob): assign it.
818 * strports.c (scm_mkstrport): set up the buffer.
819 put just the string into the stream, not cons (pos stream).
820 (stfill_buffer): new proc.
822 * ports.h: fport buffer moved into port table: to be
823 used for all port types.

852 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
853 scm_fdes_to_port and scm_redirect_port.

894 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
895 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
896 just protecting errno. some may need to be put back.

1098 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1100 * numbers.c (isfinite): Define this macro if not defined: Return a
1101 non-zero value if X is finite. (From ISO C 9x standard.)

1154 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1156 Most of this batch of changes is about how to deal with extended
1157 types when an object system is loaded into Guile. A nice object
1158 system is capable of representing Guile's types as class objects.
1160 For example, we want a regular expression to be of class <regex>.
1161 But regular expressions are smobs which aren't under direct
1162 control of the object system, so there has to be some mechanism
1163 which informs the object system that a new class should be created
1164 which can represent the smob type. I call this a "wrapper class".
1166 * objects.c: #include "smob.h";
1167 (scm_class_keyword): Removed. (Class is automatically created by
1169 (scm_smob_class): Array of smob classes indexed by smobnum.
1170 (scm_make_extended_class): "Plugin" function pointer for creation
1171 of wrapper classes for smob and struct types.
1172 (scm_class_of): Handle compiled closures. (Currently regarded as
1174 Use scm_smob_class to handle smob types;
1175 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1176 through scm_smob_class;
1179 * smob.c (scm_newsmob): Also create a wrapper class if
1180 scm_smob_class has been initialized.
1182 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1183 type code and smobnum.
1185 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1186 (scm_struct_table): Weak key table with auxilliary information for
1187 struct types. Currently used for names and wrapper classes.
1188 (scm_struct_ihashq): Hash function for structs.
1189 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1190 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1191 for accessing names of vtables. The record implementation in
1192 boot-9.scm currently uses the setter to record the name of record
1193 types. When the object system is initialized, it can use this
1194 information to create wrapper classes with suitable names.
1195 (scm_init_struct): Allocate scm_struct_table.
1196 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1197 (struct tags are a finite resource and we might want to restrict
1198 the use of tags to vtables only. E.g., Goops only uses tags for
1200 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1202 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1205 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1206 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1207 Used for access of struct table entries.
1209 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1210 (scm_hash_fold): New procedure. Used to process all entries in a
1211 hash table (in no particular order).
1213 Argh! For the umpteenth time I got compilation errors because of
1214 the "intuitive" name `kw'. This has to have an end:
1216 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1217 "kw" --> "keywords" everywhere.
1218 (I doubt that this will cause big compatibility problems since the
1219 application interface is unaffected.)
1221 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1223 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1225 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1226 column inums to native form.
1228 Improvement of backtraces: Introduces a new stack narrowing
1229 specifier, #t, for the inner cut. (See further in the comments in
1230 stacks.c:narrow_stack ().)
1232 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1233 (Used to flag certain system procedures which shouldn't turn up in
1236 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1237 modules which aren't "user" modules and the code of which
1238 shouldn't turn up in backtraces.)

1241 Extract the lookup closure from an environment.

1248 * debug.c (scm_procedure_name): Use name property in the default
1251 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1253 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1255 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1256 procedure throughout.
1258 * print.c (scm_iprin1): Removed extraneous space when printing
1259 procedure-with-setters.
1261 Entity and operator setter slots were introduced as a complement
1262 to the <procedure-with-setter> type in order to support entities
1263 and operators with setters in a reasonable and efficient way.
1264 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1267 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1280 directly through the instance.
1282 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1284 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1285 scm_struct_i_flags instead of scm_vtable_index_layout!
1287 * list.c (scm_list_star): New procedure.
1289 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1370 SYMB now point to const.
1372 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1374 * print.c (scm_iprin1): Use scm_procedure_name instead of
1375 scm_procedure_property for compiled closures.
1377 * tags.h (scm_tc7_pws): New procedure type. Four representations
1378 for procedure-with-setters were considered before selecting this
1381 1. A closure where the CODE and ENV slots are used to represent
1382 the getter and a new SETTER slot is used for the setter. The
1383 original getter is stored as a `getter' procedure property. For
1384 closure getters, the CODE and ENV slots contains a copy of the
1385 getter's CODE and ENV slots. For subr getters, the CODE contains
1388 2. A compiled closure with a call to the getter in the cclo
1389 procedure. The getter and setter are stored in slots 1 and 2.
1391 3. An entity (i.e. a struct with an associated procedure) with a
1392 call to the getter in the entity procedure and the setter stored
1393 in slot 0. The original getter is stored in slot 1.
1395 4. A new primitive procedure type supported in the evaluator. The
1396 getter and setter are stored in a GETTER and SETTER slot. A call
1397 to this procedure type results in a retrieval of the getter and a
1398 jump back to the correct eval dispatcher.
1400 Representation 4 was selected because of efficiency and
1403 Rep 1 has the advantage that there is zero penalty for closure
1404 getters, but primitive getters will get considerable overhead
1405 because the procedure-with-getter will be a closure which calls
1408 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1409 <procedure-with-setter>, but together with rep 2 it suffers from a
1410 three level dispatch for non-GOOPS getters:
1412 cclo/struct --> dispatch proc --> getter
1414 This is because the dispatch procedure must take an extra initial
1415 argument (cclo for rep 2, struct for rep 3).
1417 Rep 4 has the single disadvantage that it uses up one tc7 type
1418 code, but the plan for uniform vectors will very likely free tc7
1419 codes, so this is probably no big problem. Also note that the
1420 GETTER and SETTER slots can live directly on the heap, using the
1421 new four-word cells.
1423 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1424 SCM_SETTER): New macros.

1578 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1579 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1581 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1583 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1584 of syntactic forms, similar to SCM_PROC.
1585 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1586 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1587 for the name symbols when needed.
1589 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1591 * Makefile.in: Regenerated.
1593 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1595 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1596 take the address of _into; it might be a register. Just have
1597 scm_debug_newcell return the new cell.
1598 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1599 taking the address of a place to store it as an argument.
1600 * gc.h (scm_debug_newcell): Change declaration.
1601 (Thanks to Greg Harvey.)
1603 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1605 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1606 Replaces old names serial-array-copy! and serial-array-map!.
1608 * evalext.c (map-in-order): New name. Replaces serial-map.
1610 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
1612 * smob.c (freeprint): New function.
1613 (freecell): Use it to print freed objects, for slightly easier
1616 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1618 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1619 error if no source properties can be found for a frame. (Thanks
1620 to Christian Lynbech.)
1622 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1624 * objects.h: Removed slots direct_supers and direct_slots from the
1625 definitions of the rudimentary classes described by objects.h.
1627 * objects.c, objects.h (scm_entity_p): New procedure. Together
1628 with the predicates scm_procedure_p and scm_struct_p, this
1629 predicate makes it possible to differ between structs, entities
1632 * modules.c, modules.h (scm_resolve_module): New function.
1634 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1636 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1637 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1640 * objects.c (scm_entity_p): New procedure.
1642 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1643 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1645 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1647 * procprop.h (scm_i_procedure_arity): Added declaration.
1649 * procprop.c (scm_i_procedure_arity): Made global; New code to
1650 handle operators and entities.
1651 (scm_procedure_property): No need to call scm_procedure_p since
1652 scm_i_procedure_arity now does all necessary type checking.
1653 Added #include "objects.h".
1655 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1656 s_add_hook_x --> s_remove_hook_x.
1657 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1658 Added #include "procprop.h"
1660 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1661 (scm_make_hook): Optional argument defines number of arguments to
1663 (scm_make_named_hook): Take number of args as second arg.
1664 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1665 boot-9.scm for a while); First arg is the hook. The rest are
1666 arguments passed on to the hook procedures.
1668 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1670 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1671 scm_logbit_p): Do the computation in ulongs. This is not as nice
1672 as doing it in bignums, but at least it's good enough for
1673 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1675 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1676 subexpressions. (Thanks to Charbel Jacquin.)
1678 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1680 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1681 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1682 (scm_make_named_hook): New function.
1684 * feature.c: Added #include "eval.h".
1686 * modules.c (scm_make_module): Beautify the module.
1688 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1690 * modules.c, modules.h: New files: C interface to modules. (This
1691 is necessary in order to interface the object system to Guile
1692 properly. The guts of these modules will be replaced by the new
1693 module system in the future.)
1695 * init.c: Added #include "modules.h"
1696 (scm_boot_guile_1): Call scm_init_modules.
1697 (invoke_main_func): Call scm_post_boot_init_modules.
1699 * Makefile.am: Added modules.c, modules.x, modules.h.
1701 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1703 * procs.c: #include "objects.h"
1704 (scm_procedure_p): Return #t also on structs which are operators.
1706 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1707 <operator-metaclass> and <entity-class> to <standard-class>,
1708 <operator-class> and <entity> in order to conform with STKlos
1711 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1712 which isn't an operator.
1713 (SCM_APPLY): Ditto, but jump to badproc.
1715 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1717 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1718 Previously, structs implanted in code were interpreted as forms
1719 the operator of which was a gloc. We solve this by checking for
1720 the zero in the emulated vcell in the struct vtable. Since
1721 implanted structs always will look like forms with a gloc
1722 operator, execution will only be slowed down by maximally one
1723 extra test-and-branch per application.
1725 * evalext.c (scm_definedp): Removed check for isyms; Added a
1726 second optional argument: It is now possible to supply an
1727 evaluation environment in which to look for the symbol.
1729 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1731 * readline.c (scm_init_readline): Set
1732 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1734 * coop.c (coop_condition_variable_wait): Removed
1735 (coop_condition_variable_wait_mutex): Folded logic of
1736 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1737 prevent condvar signal lossage. Previously, another thread could
1738 start to run after unlocking the mutex but before putting the
1739 current thread on the wait queue. If that thread then would
1740 signal the first, the signal would be lost. (Thanks to Christian
1743 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1745 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1748 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1750 * objects.c (scm_i_make_class_object): Renamed from
1751 make_class_object; exported; error checking moved to
1752 scm_make_class_object and scm_make_subclass_object.
1753 (scm_make_class_object, scm_make_subclass_object): Use
1754 scm_i_make_class_object.
1755 (scm_make_subclass_object): Let the subclass have same metaclass
1758 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1760 * debug.c (scm_debug_options): Bugfix: Set the value of
1761 scm_stack_checking_enabled_p after setting debug options;
1762 #include "stackchk.h". (Thanks to Richard Polton.)
1764 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1766 * unif.c (scm_array_contents): removed unnecessary test for 0
1769 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1771 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1772 Replaced by macro `collect' in boot-9.scm.
1774 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1776 * eval.c (scm_copy_tree): Copy source properties if existent.
1778 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1779 don't, we may end up passing memoized source to a transformer.)
1781 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1783 * stack.c (get_applybody): Help function which lookups the first
1784 body form of the apply closure.
1785 (read_frames): Prevent the source of the first form of the apply
1786 closure from being recorded. This would only be confusing.
1788 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1789 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1791 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1793 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1795 (read_frames): Use SCM_MACROEXPP.
1797 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1799 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1800 don't contain interesting information since all arguments are
1801 present in the frame which applies the compiled closure anyway.);
1802 Skip the transformer application frames.
1804 * print.c (scm_iprin1): Print gsubrs as primitives.
1806 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1808 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1810 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1811 that we can identify these in a backtrace. (This change doesn't
1812 introduce any significant speed penalty.)
1814 * eval.c: Added note about `serial-map' using scm_map.
1816 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1817 readline options. They should reside in their own options array.
1819 * readline.c, readline.h (scm_readline_options,
1820 scm_readline_opts): Moved readline options here.
1822 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1824 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1825 SCM_ROCHARS instead of SCM_CHARS.
1827 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1828 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1830 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1832 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1833 This is quite important since the latter clears the
1834 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1835 every single character read...
1837 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1839 * print.c (scm_iprin1): Removed suspect looking (and indeed
1840 malevolent) semicolon after test for user supplied closure print
1841 procedure. (Thanks to Telford Tendys.)
1843 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1844 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1845 starting to search the list. Removed call to sloppy_mem_check.
1847 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1848 procedures: Same as scm_delq_x et al, but delete maximally one
1851 * options.c (scm_options, scm_init_options): GC-protect option
1852 values of type SCM. (Thanks to Telford Tendys.)
1854 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1856 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1857 make sure that there always is a "real" scm_lookupcar.
1859 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1861 * read.c, read.h (scm_read_opts): New read options
1862 "history-length" and "history-file".
1863 (scm_read_options): Stifle history to history length.
1865 * readline.c (scm_read_history, scm_write_history): New procedures.
1867 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1869 * eval.h (scm_macro_eval_x): Removed declaration.
1871 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1872 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1873 Renamed and made global.
1875 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1876 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1878 * evalext.c, evalext.h: New files. Contain non-R5RS things
1879 having to do with evaluation.
1881 * evalext.c (scm_serial_map): New procedure: Version of `map'
1882 which guarantees that the procedure is applied to the lists in
1884 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1885 returns a list of the results of the body forms instead of the
1886 result of the last body form.
1887 (scm_definedp, scm_m_undefine): Moved from eval.c
1889 * evalext.h (scm_m_sequence_to_list): Added declaration.
1891 * macros.c, macros.h: New files.
1892 (scm_procedure_to_syntax, scm_procedure_to_macro,
1893 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1894 scm_macro_name, scm_macro_transformer): Moved from eval.c
1895 (scm_make_synt): Moved from eval.c
1897 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1899 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1902 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1904 * debug.c, print.c: Added #include "macros.h".
1906 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1908 This change adds the ability to use `unread-char' multiple times
1909 without interspersed reads and adds the new procedure
1910 `unread-string'. The change is optimized for the common case of
1911 unreading a single character. This is also the reason behind the
1912 choice to store characters in the port itself: in most cases no
1913 extra malloc is required.
1915 The amount of code in some macros in ports.h has been increased to
1916 the extent that they would fit better as C functions, but, since
1917 this code belongs to the port representation, such functions
1918 should be placed in ports.c which would cause calls back and forth
1919 between ports.c and genio.c. That is not good for performance.
1920 Also, keeping them as macros allows the compiler to do some
1921 optimizations which are needed to make the current interface
1922 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1924 One benchmark (Guile startup time) indicates an increase of
1925 loading speed of 1%. Another (reading (using `read') boot-9.scm
1926 10 times) shows no change in performance.
1928 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1929 made to find a beautiful solution.)
1931 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1932 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1933 character. (SCM_CLRDY clears all.)
1934 (SCM_N_READY_CHARS): New macro: Returns number of unread
1935 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1936 (struct scm_port_table): New fields: `entry' contains port table
1937 index, `cp' points to last unread char, `cbuf' is the buffer for
1938 unread chars, `cbufend' points after end of the character buffer.
1940 * ports.h, ports.c (scm_unread_string): New procedure.
1941 (scm_grow_port_cbuf): New function.
1943 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1945 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1946 to read unread characters. Use SCM_TRY_CLRDY instead of
1949 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1951 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1953 * genio.c, genio.h (scm_ungets): New function.
1955 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1958 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1960 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1961 declarations. (Thanks to Russ McManus.)
1963 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1965 * numbers.c (num2long): As a software archeologist, I'm proud of
1966 this finding! :) Preliminary dating suggests an almost 4 year old
1967 remnant from the SCM ancestor. The sample has been removed from
1968 the finding site and is now safely stored in the repository.
1970 * numbers.h: Removed prototype for num2long.
1972 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1974 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1975 array as second arg.
1976 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1977 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1978 * gh.h: Updated and added prototypes.
1980 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1982 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1984 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1986 * guile-snarf.in: Never generate an empty file. (Thanks to
1989 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1990 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1991 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1992 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1993 gh_new_procedure5_0): Specify argument types, to appease C++
1994 compilers. (Thanks to Brad Bowman.)
1996 Bug reports from Russ McManus:
1997 * guile-snarf.in: If the CPP environment variable is set, use that
1998 as the C preprocessor, instead of the preprocessor autoconf
2000 * snarf.h (SCM_PROC): Cast the function pointer passed to
2001 scm_make_gsubr, to satisfy C++.
2003 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2004 Use the handler passed, instead of ignoring it and using
2005 gh_standard_handler. (Thanks to Etienne Bernard.)
2007 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2009 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2012 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2032 * script.c (scm_compile_shell_switches): Define
2033 use-emacs-interface in the root module, so the repl code can see
2034 it. See today's change to top-repl in ice-9/boot-9.scm.
2036 * filesys.c (set_element, get_element): Make sure that `element'
2037 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2038 Boekemeier and Jorgen "forcer" Schaefer.)
2040 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2042 * chars.c (scm_charnames): In ASCII character name table, make
2043 newlines print as #\newline by default, not #\nl.
2045 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2046 alphabetical order. Oh thrills. But it helps me know how far
2047 along in the compilation I am.
2048 * Makefile.in: Regenerated.
2050 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2052 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2053 #bytes(...) to #y(...), and syntax for short vectors from
2054 #short(...) to #h(...). This may seem nutty, but, like the other
2055 uniform vectors, byte vectors and short vectors want to have the
2056 same print and read syntax (and, more basic, want to have read
2057 syntax!). Changing the read syntax to use multiple characters
2058 after the hash sign breaks with the conventions used in R5RS and
2059 the conventions used for the other uniform vectors. It also
2060 introduces complexity in the current reader, both on the C and
2061 Scheme levels. (The Right solution is probably to change the
2062 syntax and prototypes for uniform vectors entirely.)
2064 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2066 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2067 (Thanks to Jorgen "forcer" Schaefer.)
2068 * ports.h (SCM_NOFTELL): New flag.
2069 * fports.c (local_fgets): If it's set, use the generic fgets.
2070 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2072 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2074 * script.c (scm_compile_shell_switches): Add handling of -q switch
2075 (inhibit loading of user init file).
2076 (scm_shell_usage): Add usage text for -q switch.
2077 (scm_compile_shell_switches): Always load user init file first if
2078 it is loaded at all.
2080 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2082 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2083 and is now broken under NetBSD. I can't fathom what it's trying
2084 to do, so I've replaced it with something that I do understand,
2085 which seems to work, and which isn't broken on NetBSD. "Progress?
2086 You Decide." (Thanks to Perry Metzger.)
2088 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2089 signed/unsigned comparison.
2091 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2093 Warning fixes from Greg Harvey:
2094 * unif.c (scm_array_set_x): initializer for pos
2095 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2096 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2097 initializers for field_type, since EGCS so desparately wants to
2099 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2100 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2101 when GUILE_DEBUG is defined.
2102 * dynwind.h (scm_wind_chain): Same.
2103 * ports.h (scm_pt_size, scm_pt_member): Same.
2104 * print.h (scm_current_pstate): Same.
2105 * procs.h (scm_make_cclo): Same.
2107 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2109 Handle short and long long uniform arrays properly. (Thanks to
2111 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2112 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2113 scm_tc7_llvect (long long vectors).
2115 Change the way libguile and boot-9.scm are timestamped, to try to
2116 get rid of these spurious mismatch warnings. Now both
2117 libguile/versiondat.h and ice-9/version.scm are generated directly
2118 by the configuration process, rather than having version.scm
2119 generated directly, and libguile/versiondat.h generated by the
2120 Makefile, which is generated by configure. It seems that
2121 sometimes the Makefile would change, but versiondat.h depends on
2122 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2123 * Makefile.am (versiondat.h): Target removed; this is generated
2124 directly by the configure script now.
2125 (BUILT_SOURCES): Remove versiondat.h.
2126 * versiondat.h.in: New file, transformed by the configure script
2128 * Makefile.in: Regenerated.
2130 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2131 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2132 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2133 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2134 if we want to use them in a header file some day, we can. (Thanks
2135 to Michael Livshin.)
2137 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2138 SCM numbers, so we won't have rollover problems; the range of a
2139 signed long in milliseconds is about 25 days. (Thanks to Karl
2142 Don't redefine sleep and usleep; fix this problem now.
2143 * coop.c (sleep, usleep): Remove declarations; we don't use or
2144 redefine these any more.
2145 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2146 job of usleep and sleep in a thread-friendly way. We can use
2147 these in the rest of Guile. Define versions for systems both with
2148 and without iselect.
2149 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2150 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2151 we're just using it, not redefining it, we can use a K&R style
2153 (sleep): Declare this, too, if the system hasn't.
2154 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2155 scm_uthread_sleep if they're available; otherwise, just call the
2157 * scmconfig.h.in: Regenerated.
2159 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2161 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2163 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2165 * threads.c: Doc fix.
2167 The argument type of usleep varies from system to system,
2168 as does the return type. We really shouldn't be redefining usleep
2169 at all, but I don't have time to clean that up before the 1.3.
2170 release. It's on the schedule for afterwards. (Thanks to Julian
2172 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2174 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2175 * scmconfig.h: Regenerated.
2177 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2178 right way to handle system variation. Autoconf's approach is the
2180 * simpos.h (scm_software_type): Declaration deleted.
2182 * script.c (scm_find_executable): Don't test if unix is #defined
2183 here; first, NetBSD doesn't #define it, and second, it's the wrong
2184 way to go about these things. (Thanks to Perry Metzger.)
2185 (dld_find_executable): Delete this MSDOS support code. This isn't
2186 the way we want to support this; it needs to be rethunk at a
2189 * genio.c (scm_do_read_line): Don't just politely check that the
2190 line was either non-empty or EOF. Abort if it's empty and not
2193 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2195 * scmconfig.h.in: Regenerated.
2197 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2200 * genio.c (scm_do_read_line): Count lines correctly when the file
2201 doesn't end in a newline.
2203 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2205 * genio.c (scm_do_read_line): Maintain the line count correctly.
2206 (Thanks to Harvey J. Stein and Greg Harvey.)
2208 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2211 * numbers.c (big2str): Protect t from garbage collection until
2212 we're done. (Thanks to Gary Houston.)
2214 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2216 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2218 * Makefile.in: Regenerated.
2220 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2221 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2224 Do magic to mix reads and writes on stdio FILE-based ports.
2225 (Thanks to Christian Lynbech.)
2226 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2228 (pre_read, pre_write): New functions.
2229 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2230 local_fputs): Call them.
2231 (local_fflush): Mark the port as ready for reading and writing.
2232 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2233 flags on new port objects. This might not be accurate --- who
2234 knows what state the FILE * is in when we get it --- but it won't
2235 do extraneous calls to fflush or fseek, so it's no worse than the
2236 behavior before this change.
2237 * ports.h: Add comment.
2239 Centralize the creation of port objects based on stdio FILE * in
2240 fports.c; don't just throw them together anywhere.
2241 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2242 what the rest of Guile wants. Don't set the revealed count;
2243 that's only appropriate for stdin, stdout, stderr.
2244 (scm_standard_stream_to_port): This function does set the revealed
2246 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2247 not scm_stdio_to_port.
2248 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2249 * fports.c (scm_open_file): Same.
2250 * posix.c (scm_pipe): Same.
2251 * socket.c (scm_sock_fd_to_port): Same.
2252 * ioext.c (scm_fdopen): Same.
2253 (scm_freopen): Moved from here to...
2254 * fports.c (scm_freopen): ... here. This is really something that
2255 munges the internals of an fport, so it should go here.
2256 * fports.h (scm_stdio_to_port): Adjust prototype.
2257 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2258 * ioext.h (scm_freopen): Prototype removed.
2260 * filesys.c (set_element, get_element): This can work on both pipe
2261 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2264 * scmconfig.h.in: Regenerated.
2266 Change the definition of the functions in scm_ptobfuns so that
2267 they get passed the port object, not the port's stream.
2268 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2269 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2270 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2271 Pass the port itself to the scm_ptobs function.
2272 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2273 scm_generic_fgets): Same.
2274 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2275 getc_void_port, fgets_void_port, close_void_port): Just change the
2276 argument names; these functions don't really do anything.
2277 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2278 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2279 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2280 Also, use prototyped definitions, and get rid of the extra
2282 (scm_fptob, scm_pipob): We don't need casts here any more.
2283 * strports.c (prinstpt): Use prototype declarations.
2284 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2285 and use SCM_STREAM to get the string info. Also, use prototyped
2286 definitions, and get rid of the extra declarations.
2287 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2290 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2291 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2293 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2294 scm_fgets, for consistency.
2295 (scm_fptop, scm_pipob): References updated.
2297 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2299 Include the source location in error messages for scripts.
2300 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2301 stack is still there when we catch the error.
2302 * throw.c (handler_message): If we are handling an error with a
2303 message, then put together the proper arguments and call
2304 scm_display_error, instead of scm_display_error_message. That
2305 displays source location, if it can find it.
2307 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2309 * gc.c (scm_unprotect_object): Change this so that calls to
2310 scm_protect_object and scm_unprotect_object nest properly.
2311 (scm_protect_object): Doc fixes.
2313 * strings.c (scm_string_set_x): Require the argument to be a
2314 writable string, not a substring or a symbol.
2315 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2316 (Thanks to John Redford and Charbel Jacquin.)
2318 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2320 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2322 * eval.c (safe_setjmp): Remove this misunderstanding.
2323 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2326 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2328 * libguile.h: Mark these as C declarations, for compilation by C++
2331 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2332 __cplusplus clause. I seriously doubt this ever worked the way
2333 the author seems to have intended.
2335 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2337 Utterly needless cleanups to hopelessly messy code.
2338 * ports.c: Doc fixes.
2339 (scm_fflush): Moved to ...
2340 * genio.c (scm_fflush): ... here, amongst all the other port
2341 method invocation functions.
2342 * genio.h, ports.h: The prototype moves too.
2344 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2346 * backtrace.c (display_error_body): The current frame does not
2347 always have a parent frame; consider a function called directly
2348 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2351 * alloca.c (alloca): Undo yesterday's changes, and simply call
2352 malloc directly for storage, and abort if we don't get what we
2353 want. The situation is much simpler --- just call malloc. Emacs
2354 has bizarre/evil requirements (signal handlers might malloc unless
2355 you set this global flag, so you have to set the flag around all
2356 calls to malloc) which we are certainly not going to conform to,
2357 so we can do the simple and obvious thing.
2359 * coop.c (coop_condition_variable_wait): Make this function
2360 static. It's only useful internally --- you should never just
2361 wait on a condition variable.
2362 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2364 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2366 * unif.c (scm_array_set_x): Accept any kind of number as an
2367 element for a uniform vector of doubles. This is more consistent
2368 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2370 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2371 works; I can't conveniently test it myself. (Thanks to Dvid
2372 Tillman for the bug report.)
2374 * init.c: Doc fixes.
2376 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2377 from here, not from scm_compile_shell_switches (which is a pretty
2378 dumb place to do it).
2379 (scm_load_startup_files): New function.
2380 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2381 * script.c (scm_compile_shell_switches): Don't load the startup
2383 (scm_ice_9_already_loaded): Variable moved.
2384 * init.c (scm_load_startup_files): Prototype for new function.
2385 * gh_init.c (gh_enter): Doc fix.
2387 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2389 Some anti-warning changes from Greg Harvey.
2390 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2391 warnings when it doesn't understand our NORETURN declarations in
2393 * posix.c (scm_mknod): Similar.
2395 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2397 * posix.c (scm_getpwuid): If we can't find an entry, return our
2398 own message, instead of using scm_syserror --- the getpwMUMBLE
2399 functions don't set `errno' to anything interesting.
2401 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2403 Get rid of warnings from the cooperative threading system.
2404 * threads.h (scm_single_thread_p, scm_yield,
2405 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2406 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2407 scm_wait_condition_variable, scm_signal_condition_variable): Add
2408 prototypes for these Scheme-visible functions.
2409 * coop-defs.h (coop_next_runnable_thread,
2410 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2411 Prototypes for these here, even though they're from iselect.c.
2412 (coop_condition_variable_wait, coop_join): Add prototypes.
2413 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2414 scm_threads_free_condvar): Make these smob functions static.
2415 * coop-threads.h (coop_init): Give this a real prototype.
2416 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2417 (coop_next_runnable_thread): No need to provide prototype; it's in
2420 * scmconfig.h.in: .detarenegeR
2422 * iselect.c, threads.c: Doc fixes.
2424 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2426 * Makefile.in: Regenerated with a patched automake, to get
2427 dependency generation right when using EGCS.
2429 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2430 warning. (Thanks to Robert Pluim.)
2432 * inet_aton.c (inet_aton): Reassure the compiler that the
2433 arguments to the <ctype.h> macros are all unsigned characters, not
2436 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2438 Getting rid of more warnings...
2439 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2440 today's change to ../configure.in.
2441 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2442 * scmconfig.h.in: Regenertaded.de.,.__
2443 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2444 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2447 * readline.c: Doc fix.
2448 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2449 * readline.h (scm_filename_completion_function): Add prototype.
2450 (scm_init_readline): Make this into a prototype.
2452 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2453 declare this, instead of calling scm_make_subr manually.
2455 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2457 * readline.h (scm_init_readline): Add prototype for this.
2458 (scm_init_readline): Make this a real prototype.
2460 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2462 Warning fixes from Maciej Stachowiak:
2463 * backtrace.h (scm_display_application, scm_backtrace): Add
2465 * debug.c (scm_m_start_stack): Make this function static.
2466 * fluids.h (scm_fluid_p): Add prototype.
2467 * procprop.c (scm_i_procedure_arity): Make this function static.
2468 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2469 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2470 * root.h (scm_dynamic_root): Add external prototype.
2471 * scmsigs.h (scm_usleep): Add external prototype.
2472 * script.h (scm_init_script): Use prototype, not K&R decl.
2473 * stacks.h (scm_stack_id): Add external prototype.
2474 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2476 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2478 * gh.h: took out the definitions of vset and vref, since they are
2479 replaced by the proper vector routines that correspond to the R4RS
2482 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2484 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2485 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2486 third argument, a C expression that should result in a SCM value,
2487 which is used to initialize the variable. Reimplemented
2488 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2491 * version.h (scm_libguile_config_stamp): Add prototype.
2492 (From Maciej Stachowiak.)
2494 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2496 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2497 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2499 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2501 * print.c (scm_iprin1): Rather than having one i, and using it in
2502 several places, declare a fresh i local to each block where it is
2503 used, and give it a signedness appropriate to its use in each case.
2504 (scm_iprlist): Same.
2506 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2507 comparison warnings.
2509 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2510 signed/unsigned clashes.
2512 * posix.h (scm_tmpnam): Added prototype.
2514 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2515 scm_make_subclass_object): Add external prototypes.
2517 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2518 comparison is okay here.
2520 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2522 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2523 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2525 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2528 * load.c (swap_port): Make this function static.
2530 * load.c (scm_search_path): Make max_path_len and max_ext_len
2531 unsigned, since they're compared against string sizes.
2533 * load.c (init_build_info): Make i unsigned.
2535 * ioext.h (scm_read_line): Add prototype.
2537 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2538 scm_hash_fn_remove_x): Make hash bucket index local variable k
2539 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2540 accurately as possible.
2542 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2543 comparisons, and range checking to make sure those casts are
2546 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2547 signed/unsigned comparisons.
2549 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2550 avoid signed/unsigned comparisons.
2551 * smob.h (scm_numsmob): Change extern declaration to match.
2553 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2554 avoid signed/unsigned comparisons.
2555 * ports.h (scm_numptob): Change extern declaration to match.
2556 (scm_current_load_port, scm_set_port_line_x,
2557 scm_set_port_column_x): New prototypes.
2559 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2560 test code, and it causes warnings.
2562 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2563 gh_uniform_vector_ref): Added prototypes.
2565 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2566 debugging support unconditionally. That's backtrace.c, stack.c,
2567 debug.c, and srcprop.c.
2568 (EXTRA_libguile_la_SOURCES): Omit those from here.
2569 * Makefile.in: Regenerated.
2571 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2573 * options.c (scm_options): Bugfix: Allow empty list of options!
2575 * debug.c, debug.h (scm_single_step): Removed.
2576 (scm_with_traps): New procedure. This procedure could easily be
2577 written in Scheme but needs to be highly optimized.
2579 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2581 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2582 Check SCM_TRAPS_P before trapping.
2584 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2586 Changes to avoid signed/unsigned comparison warnings.
2587 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2588 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2589 so they can have appropriate types for each application. Make i
2590 signed. Use initializers in some spots. I'll probably pay for
2592 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2593 (scm_must_realloc): Make nm unsigned.
2594 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2595 (scm_init_storage): Use prototype-style definition, and make the
2597 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2598 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2600 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2601 avoid signed/unsigned comparison warnings, and because the return
2602 value of readlink may be -1. Don't bother casting the third
2603 argument to readlink.
2605 * filesys.c (scm_dirname, scm_basename): Move these to their own
2606 page, at the end of the file.
2607 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2609 * eval.h (scm_eval_options_interface): Add external prototype for this.
2610 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2612 * eval.c (scm_lookupcar1): Make this static.
2614 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2615 Make these prototype declarations, not K&R-style.
2617 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2618 unsigned comparison warning.
2620 * appinit.c: File removed. It had a single function in it, empty,
2621 whose reason for existence is explained in no documentation or
2622 comment. I think it's there as a default for some Tcl-style
2623 initialization, but Tcl abandoned that approach a while ago.
2624 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2625 (BUILT_SOURCES): Remove appinit.x.
2626 * Makefile.in: Regenerated.
2628 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2630 * Makefile.in: Regenerated using the last public version of
2631 automake, not the hacked Cygnus version.
2633 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2635 Remove Totoro kludge.
2636 * Makefile.in, scmconfig.h.in: Regenerated.
2637 * init.c, readline.c: Don't check if TOTORO is #defined.
2639 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2641 * Makefile.am: Adjust for new thread configuration system.
2642 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2643 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2645 (THREAD_LIBS): Definition deleted; automake will generate such
2646 things automatically.
2647 * Makefile.in: Regenerated.
2649 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2651 Simplify smob and port marking; set the mark bit in the generic
2652 marking code, and make marker routines only responsible for
2653 turning up outgoing pointers.
2654 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2655 before calling the marking function. Don't call the marking
2656 function if it's zero.
2657 * markers.c (scm_mark0): Just return #f. This function isn't
2658 necessary at all now, but it's harmless to call it. We'll leave
2659 it in so other folks' code doesn't croak at link time.
2660 (scm_markcdr): Don't call SCM_SETGC8MARK.
2661 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2662 * dynl.c (mark_dynl_obj): Same.
2663 * root.c (mark_root): Same.
2664 * srcprop.c (marksrcprops): Same.
2665 * unif.c (markra): Same.
2666 * variable.c (scm_markvar): Same.
2667 * ports.c (scm_markstream): Same.
2668 (void_port_ptob): Specify zero for our marking function.
2669 * debug.c (debugobjsmob): Same.
2670 * dynwind.c (guardsmob): Same.
2671 * filesys.c (dir_smob): Same.
2672 * fluids.c (fluid_smob): Same.
2673 * fports.c (scm_fptob, scm_pipob): Same.
2674 * mallocs.c (mallocsmob): Same.
2675 * regex-posix.c (regex_t_smob): Same.
2676 * smob.c (freecell, flob, bigob): Same.
2677 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2678 * throw.c (jbsmob, lazy_catch_funs): Same.
2680 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2682 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2683 scm_copy_tree on code in order not to let memoized code to leak
2684 out. Thus, scm_copy_tree needs to copy vectors as well since
2685 quasiquote can introduce evaluated code also inside vector
2688 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2690 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2692 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2693 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2696 * unif.c: Say that ivect and uvect are of type signed and unsigned
2697 long instead of int in commentary so that it correctly describes
2700 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2702 * stime.c: Removed declaration of strptime. (It should be
2703 declared by the system headers. If it turns out that some systems
2704 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2706 * stime.h: Renamed TIMEH --> STIMEH
2708 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2709 to increase portability, don't use structure assignment.
2710 (Thanks to Nicolas Neuss.)
2712 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2714 (finalize_fd_sets): Added empty statement after last case label.
2715 (Thanks to Nicolas Neuss.)
2717 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2720 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2722 * init.c, readline.c: OK, I won't have these readline.x bug
2723 reports anymore. We've had them since April. The current reason
2724 is a completely unintelligible failure of totoro.red-bean.com to
2725 do the test for rl_getc_function in libreadline correctly. This
2726 kludge overrides the test if we're on totoro so that the snapshot
2727 generation process can work.
2729 * readline.c: Define a strdup replacement if not existent on system.
2731 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2733 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2734 This change makes scm_make_vector R5RS compatible. We cannot keep
2735 the third argument since people want to be able to deduce the form
2736 of the C function call only by looking at R5RS. (At the same time
2737 we have removed some unnecessary complexity!)
2739 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2740 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2741 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2742 argument in call to scm_make_vector.
2744 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2746 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2747 This macro is useful in applications.
2749 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2751 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2752 (scm_parse_path, scm_search_path): New Scheme level procedures.
2754 * load.h (scm_internal_parse_path, scm_parse_path,
2755 scm_search_path): Declared.
2757 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2759 * filesys.c (dirname, basename): New procedures.
2761 * init.c (scm_boot_guile_1): Removed condition around
2764 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2765 new data type (guards) for representation of C level guards and
2766 data on the wind chain.
2767 (scm_internal_dynamic_wind): New function.
2769 * dynwind.h: Declare scm_internal_dynamic_wind.
2771 * root.h (scm_root_state): Added scm_cur_loadp.
2773 * root.c (mark_root): Added comment about cur_loadp.
2775 * load.c: #include "dynwind.h";
2776 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2779 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2781 * ports.c (current-load-port): New procedure.
2783 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2785 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2786 not a tty, return #f.
2788 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2789 to Julian Satchell and Roland Kaufmann.)
2791 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2792 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2794 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2796 * debug.h, debug.c (scm_start_stack): New function. Implements
2797 the guts of old scm_m_start_stack.
2799 * debug.c (scm_m_start_stack): Use scm_start_stack.
2801 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2802 start_stack and restart_stack. (These have static scope.)
2804 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2806 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2807 readline functions to come in release 2.3. (Thanks to Chet
2809 (handle_errors): Use the above functions.
2811 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2813 * readline.c: Improvements for readline support: Handle errors
2814 better; Implement before-read-hook.
2816 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2818 * init.c (scm_boot_guile_1), readline.c: Test for
2819 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2820 assure that we have version >= 2.1.)
2822 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2824 * readline.c (scm_readline): Defer interrupts while we're calling
2827 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2828 away the string to add_history.
2829 (completion_function): Do completion for readline. (Thanks to
2831 (scm_filename_completion_function): New procedure: Filename
2833 (current_input_getc): New function. Use this one instead of
2834 standard getc from readline.
2836 * throw.c, throw.h (scm_handle_by_throw): New function: This
2837 handler throws errors to next handler on the dynwind chain.
2839 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2841 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2844 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2846 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2848 (scm_procedure_properties): Modified to return arity together with
2850 (scm_procedure_property): Added the read-only property `arity'.
2851 (scm_set_procedure_property_x): It is an error to set the `arity'
2854 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2855 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2857 * procprop.h (scm_sym_arity): New symbol.
2859 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2860 to set the dispatch procedure of an operator or entity object.
2862 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2863 Made procedure slots read-only.
2865 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2866 scm_tcs_cons_gloc case in zero args switch; Fixed args
2867 construction for operators in scm_tcs_cons_gloc case in two args
2870 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2872 * fluids.c: Removed use of assert.h (in order to avoid
2875 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2877 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2879 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2880 change makes the evaluator safer at the cost of evaluation speed.
2881 It handles the case when the user has added a non-immediate
2882 improper end of the application form, e.g., `(+ 0 . x)'.
2883 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2884 minimize the extra cost as much as possible. The new code is
2885 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2886 problem with structs planted directly in the code (e.g. by a
2887 macro). This no longer causes segmentation fault. (Thanks to
2890 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2891 arg `proc' in order to be able to throw errors; New argument
2894 * Removed extra #include "debug.h"
2896 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2898 * scmsigs.c: Declare usleep as returning void on some systems.
2899 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2902 * coop.c (usleep): Return void on some systems.
2904 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2906 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2908 * coop.c: Changed return type of usleep to int.
2910 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2911 isn't found in the OS.
2913 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2914 isn't enabled. (Thought that I had made this change ages ago...)
2916 * iselect.c: Declare bzero if not defined by OS.
2918 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2920 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2921 condition. (Thanks to John Tobey.)
2923 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2924 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2927 * __scm.h: Start the long-term project of moving to POSIX threads.
2928 Phase 1: Classification of all critical sections.
2929 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2930 for A sections. (See comments in __scm.h for details.)
2932 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2933 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2935 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2937 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2938 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2939 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2940 dependencies on $(srcdir)/Makefile.in
2941 $(top_builddir)/config.status in order to avoid circularity.
2943 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2944 from argc if argc was 0 initially.
2946 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2947 in generation of libpath.h.
2949 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2951 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2952 libguile from 2 to 3.
2954 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2956 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2958 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2960 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2961 scm_set_port_column_x, scm_port_filename,
2962 scm_set_port_filename_x): Removed optional arguments. Added
2963 proper argument checking.
2965 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2966 stack size in machine words.
2968 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2969 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2970 to Ole Myren Röhne.)
2972 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2974 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2975 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2977 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2980 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2981 procedure apply: Copy argument lists before pushing them unto the
2982 environment so that the environment won't get mutated due to
2983 manipulation of procedure arguments. This should perhaps be
2984 regarded as a temporary solution until someone finds a more
2985 efficient one. (Thanks to Maciej Stachowiak.)
2987 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2989 * script.c (scm_compile_shell_switches): Use "guile" as default
2990 zero arg if argc is NULL.
2992 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2994 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2995 is zero. (Thanks to Dirk Herrmann.)
2997 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2999 * ports.c (scm_add_to_port_table): First line is now line 0
3000 (was 1). (Interface changed according to suggestion by Per
3003 * backtrace.c (display_header): Add 1 to line and column numbers
3004 when presenting them to the user.
3006 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3007 from debug.c --> eval.c
3009 * eval.h, eval.c (scm_eval_options_interface): New options
3011 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3012 i.e. stacks for new threads.
3014 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3016 * eval.c (unsafe_setjmp): Removed with #if 0.
3018 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3021 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3022 to avoid compiler warnings.
3024 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3026 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3028 * throw.c (handler_message): Print message on current error port
3029 instead of default error port. (Thanks to Maciej Stachowiak.)
3031 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3033 * ports.c (scm_add_to_port_table): allocate in units of
3034 struct scm_port_table *, not struct scm_port_table.
3035 * posix.c (scm_close_pipe): remove the port from the port table
3037 Thanks to Rob Engle for both fixes.
3039 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3041 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3042 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3044 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3046 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3048 * backtrace.c (display_error_body, display_backtrace_body),
3049 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3050 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3051 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3052 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3055 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3056 don't receive the jmpbuf arg anylonger.
3057 (scm_catch): Don't accept a #f tag.
3058 (scm_throw): Check that key is a symbol.
3059 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3061 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3063 * async.c (async_pending): Removed declaration.
3065 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3067 * dynwind.c (scm_wind_chain): New debug function.
3069 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3070 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3071 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3072 extra layer of functions around the body and handler of a thread.
3073 This extra layer makes sure that the handler is called in the
3074 dynamic context of the surround (= empty dynwind list), but under
3075 the *dynamic root* of the body. We can not use the dynamic root
3076 of the surround since that root belongs to another thread => stack
3077 is not handled correctly. It may seem ugly to use this extra
3078 layer, but the extra cost in terms of execution time is really
3079 negligible compared to the total amount of time required to create
3080 a thread, and it would reduce maintainability to duplicate the
3081 crucial and complicated steps performed by cwdr.
3083 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3084 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3085 get re-enabled. The important effect of this is that interrupts
3086 are blocked during thread switching so that thread data structures
3087 don't risk getting messed up by an unfortunate signal.
3088 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3089 seems to do more aggressive optimization which actually move
3090 instructions around in these macros in a fatal way. Therefore:
3091 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3092 just superstitious...)
3093 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3094 This macro should be used instead of SCM_ASYNC_TICK since the
3095 latter doesn't do context switches any more.
3097 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3098 instead of SCM_ASYNC_TICK.
3100 * coop.c, iselect.c: Since thread switches are now performed with
3101 interrupts masked, we can't use the old mechanism of delivering
3102 signals immediately when they arrive. Signals must instead be
3103 delivered when the asyncs run *after* the end of the critical
3104 section in scm_internal_select. But this also means after context
3105 switch so that the signal will be delivered to a different thread.
3106 To avoid this, I have changed the protocol of
3107 coop_wait_for_runnable_thread and friends so that they are allowed
3108 to return the original thread. So, if a signal arrives during
3109 scm_internal_select, we won't any longer be forced do a context
3110 switch, but can remain in the same thread and deliver the signal
3113 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3114 scm_asyncs_pending and made it global.
3116 * iselect.c: Small fixes.
3118 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3119 coop_condition_variable_init, coop_condition_variable_wait,
3120 coop_condition_variable_signal): Changed return type from `void'
3121 to `int'. This is to adhere closer to the pthreads interface.
3122 This, in turn, is part of an attempt to provide C versions of the
3123 mutex and condition variable primitives which can be part of a
3124 frontend to COOP or pthreads.
3126 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3127 coop_condition_variable_destroy): New functions.
3129 * coop-threads.c (scm_wait_condition_variable): Use
3130 coop_condition_variable_wait_mutex.
3132 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3133 Definitions moved to coop-defs.h.
3135 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3136 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3137 scm_cond_destroy): New C interface to mutecis and cond vars.
3139 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3141 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3143 * iselect.c: Now several threads can wait on the same file
3144 descriptor. The behaviour is compatible with OS select: All
3145 threads waiting for the fd return with the same status.
3147 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3149 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3150 Can spawn a thread from application C code.
3152 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3154 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3155 gh_doubles2scm): New functions.
3157 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3159 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3160 commented-out version of gh_eval_str()
3162 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3164 * socket.c (scm_bind): free soka after use.
3166 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3168 * stime.c (tzvar): new variable.
3169 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3170 avoid memory leaks when allocating.
3172 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3174 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3177 * gc.c, tags.h: Doc fixes.
3179 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3181 * eval.c (macro-eval!): Removed. This function was a design bug.
3182 It allowed memoized code to leak out to the scheme level. Most
3183 things that you could do with `macro-eval!' can be done with
3186 1997-12-20 Tim Pierce <twp@skepsis.com>
3188 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3189 scm_fgets now depends on ftell(3) to know how many bytes were
3192 1997-12-15 Tim Pierce <twp@skepsis.com>
3194 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3195 dealing with strings.
3197 1997-12-13 Tim Pierce <twp@skepsis.com>
3199 Make %read-line more suitable for implementing read-line efficiently.
3200 * ioext.c (scm_read_line): Strip the terminating newline from a
3201 string, and return a cons of the string and its terminator.
3203 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3204 of the string that is read is stored in this memory location.
3205 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3206 * genio.c, genio.h (scm_do_read_line): Update caller.
3207 * ports.h (scm_ptobfuns): Update typedef.
3208 * fports.c (scm_fptob, scm_pipob): Update struct.
3210 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3212 * filesys.c (set_element): Return file descriptor.
3213 (fill_select_type): Return the highest file descriptor.
3214 (scm_select): Tell select about the highest file descriptor. On
3215 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3216 Therefore the extra overhead for calculating the maximum fd seems
3217 to be more than compensated. Is this correct? In any case,
3218 scm_internal_select will be much faster with this info.
3219 (scm_select, fill_select_type, set_element): Don't accept any kind
3220 of object in the file descriptor list or vector.
3222 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3224 * iselect.c (finalize_fd_sets): Bugfix.
3226 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3228 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3229 when using scm_internal_select (since we might switch to another
3232 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3234 * simpos.c (scm_system): always define: use sysmissing if not
3235 available. Check for HAVE_SYSTEM instead of _Windows (does
3236 Windows lack system or does it have an unusable one?).
3237 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3238 Let the argument be optional: if not supplied, call system(NULL).
3240 * ports.c (scm_close_port): relax the type check from OPPORTP to
3241 PORTP; closing a closed port is allowed.
3243 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3245 * fports.c (scm_fgets): Return if the last char in a chunk is
3246 newline. When fgets returns a string whose length is `size-1', it
3247 is ambiguous whether a whole line was retrieved, so we must check
3248 explicitly whether a line terminator is present.
3250 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3253 before taking the CDR. (Thanks to Harald Meland.)
3255 * filesys.c (scm_stat): Slightly optimized.
3257 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3259 * ports.c (scm_close_port): Make sure the port is open before
3262 * guile-snarf.in: Pass args through to gcc in a way that preserves
3263 whitespace boundaries. (Thanks to Greg Badros.)
3265 1997-12-02 Tim Pierce <twp@skepsis.com>
3267 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3268 statement. (Thanks to Doug Evans for pointing this out.)
3270 1997-12-01 Tim Pierce <twp@skepsis.com>
3272 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3274 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3276 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3277 errno macro expansion of this field name. (errno is a C
3278 preprocessor macro on some systems.)
3280 1997-11-29 Tim Pierce <twp@skepsis.com>
3282 * iselect.c: Doc fix.
3284 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3286 * init.c (scm_start_stack): Removed initialization of
3287 scm_the_last_stack_var.
3289 * backtrace.h: Declare scm_the_last_stack_var.
3291 * backtrace.c: Define scm_the_last_stack_var.
3293 * root.c (mark_root): Don't mark the_last_stack_var.
3295 * root.h (scm_root_state): Removed the_last_stack_var.
3297 * throw.c: Added #include "fluids.h"
3298 (ss_handler): `the-last-stack' is now a fluid.
3300 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3301 --> the_last_stack_fluid.
3303 * backtrace.c: Added #include "fluids.h"
3304 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3305 (scm_backtrace): `the-last-stack' is now a fluid.
3307 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3308 after scm_init_fluids.
3310 1997-11-28 Tim Pierce <twp@skepsis.com>
3312 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3314 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3315 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3317 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3319 * iselect.c (coop_next_runnable_thread,
3320 coop_wait_for_runnable_thread): Disable interrupts so that no
3321 async is executed before a potential error_revive.
3322 (scm_internal_select): Disable interrupts during the parts of the
3323 code which manipulate the sleep queue and the file descriptors.
3325 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3327 * Makefile.am: Added iselect.c and iselect.h.
3329 * coop.c (coop_qinit): Initialize fields used by
3330 scm_internal_select.
3331 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3332 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3333 replacement in iselect.c.
3334 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3335 coop_join): If GUILE_ISELECT enabled, use
3336 coop_wait_for_runnable_thread instead of
3337 coop_next_runnable_thread.
3338 (usleep, sleep): New replacements for system functions if
3339 GUILE_ISELECT is enabled.
3341 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3343 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3345 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3346 iselect.h. Implement Scheme level `select' using
3347 scm_internal_select. (See NEWS.)
3349 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3351 * init.c: Call scm_init_iselect.
3353 * iselect.h, iselect.c: New files. Implements
3354 scm_internal_select. (See NEWS.)
3356 1997-11-27 Tim Pierce <twp@skepsis.com>
3358 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3359 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3360 and scm_must_free, since ultimately the string returned will be copied
3361 by scm_makfrom0str anyway. Also, read any characters that may have
3362 been pushed onto the port with scm_ungetc.
3363 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3364 * ioext.c (scm_read_line): Free string after Guilifying it.
3365 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3367 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3369 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3371 * gh.h: Safely wrap prototypes for c++ usage.
3373 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3375 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3376 gh_repl (argc, argv).
3378 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3380 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3381 and to invoke scm_shell().
3382 (gh_launch_pad): took out the loading of boot-9.scm from here,
3383 since it is probably best to let the user control that. In fact,
3384 gh_repl() now invokes scm_shell() which does that.
3386 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3388 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3391 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3393 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3394 yesterday's underscore patch. (Thanks to Marius Vollmer for
3397 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3399 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3400 DLSYM_ADDS_USCORE is not defined.
3402 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3404 * gh_data.c (gh_uniform_vector_length):
3405 (gh_uniform_vector_ref): started implementing the uniform types in
3408 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3410 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3411 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3413 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3415 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3416 configure.in was changed).
3418 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3420 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3421 * Makefile.in: Regenerated.
3423 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3425 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3426 OPORT is an `open' port, not an output port.
3428 * filesys.c (scm_close, set_element, get_element, scm_chown,
3429 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3430 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3431 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3432 scm_close_port, scm_port_line, scm_set_port_line_x,
3433 scm_port_column, scm_set_port_column_x, scm_port_filename,
3434 scm_set_port_filename_x, scm_port_mode,
3435 scm_close_all_ports_except, scm_set_current_output_port,
3436 scm_set_current_error_port): Likewise
3437 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3438 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3440 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3441 * backtrace.c (display_backtrace_body): Likewise
3442 * fports (scm_setvbuf): Likewise
3443 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3444 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3445 scm_getpeername, scm_send, scm_sendto): Likewise
3446 * unif.c (scm_uniform_array_write): Likewise
3448 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3450 Minor problems with substring-related tag changes.
3451 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3452 exactly what we want to leave in to detect substrings.
3453 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3454 * tags.h: Fix diagrams and comments describing the S tag bit;
3455 remove vestigial remarks about the D tag bit.
3456 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3457 * strings.c: Formatting tweaks.
3459 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3460 variable first; then SCHEME_LOAD_PATH, with a warning message.
3461 (scm_parse_path): New function.
3462 * script.c: Doc fixes.
3464 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3466 Readline support, from Daniel Risacher.
3467 * readline.c, readline.h: New files.
3468 * init.c: #include "readline.h".
3469 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3470 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3471 * Makefile.in: Regenerated.
3472 * scmconfig.h.in: Regenerated, after change to ../configure.
3474 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3476 * gh.h: gh_vector_set -> gh_vector_set_x
3478 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3480 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3481 with the ! -> _x mapping when going from Scheme to C.
3483 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3485 * gh.h (gh_reverse):
3493 (gh_assoc): added these gh_ functions implemented as macros.
3495 * gh_predicates.c (gh_null_p):
3496 (gh_string_equal_p): added these two missing predicates.
3498 * gh_list.c (gh_append):
3503 (gh_set_cdr_x): added these routines as I go through and try to
3504 complete the picture R4RS functions that should be mirrored in the
3507 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3509 * tags.h (scm_tc7_substring): Changed the comment and code to
3510 conform with the changes below. Folks! We have suddenly two new
3511 free tc7 codes!!! Jummy, jummy!
3513 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3515 * Makefile.in: Rebuilt.
3516 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3518 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3519 * unif.c (scm_vector_set_length_x): Don't handle multibyte
3521 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
3522 (scm_tag): Don't handle multibyte strings.
3523 * read.c: Don't include mbstrings.h.

3528 * hash.c (scm_hasher): Don't handle mbstrings.
3529 * gscm.c (gscm_run_scm): Don't init mbstrings module.
3530 * gc.c (scm_gc_mark): Don't handle mbstrings.
3531 (scm_gc_sweep): Likewise.
3532 * eval.c (SCM_CEVAL): Don't handle mbstrings.
3533 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
3534 * tags.h (SCM_TYP7SD): Removed.
3535 (SCM_TYP7D): Removed.
3536 (scm_tc7_mb_string): Removed.
3537 (scm_tc7_mb_substring): Removed.
3538 * print.c (scm_iprin1): Handle char printing directly. Don't
3540 Don't include "mbstrings.h".
3541 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3542 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3544 Don't include "mbstrings.h".
3545 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3546 (SCM_SYMBOL_SLOTS): Define as 4.
3547 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
3548 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3549 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3550 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3551 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
3552 ("gen"-less) I/O function names.
3553 * ports.c (scm_add_to_port_table): Don't set port's
3555 * ports.h (scm_port_representation_type): Removed.
3556 (scm_string_representation_type): Removed.
3557 (struct scm_port_table ): Removed representation field.
3558 (SCM_PORT_REPRESENTATION): Removed.
3559 (SCM_SET_PORT_REPRESENTATION): Removed.
3560 * genio.h: Use new function names.
3561 * genio.c: Don't include "extchrs.h".
3562 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
3564 (scm_putc, scm_puts, scm_lfwrite): No longer static.
3565 (scm_getc): No longer static; handle line and column changes.
3566 (scm_ungetc): Renamed from scm_gen_ungetc.
3567 (scm_do_read_line): Renamed from scm_gen_read_line.
3568 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3569 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3571 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3573 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3575 * gh_test_c.c (c_vector_test): some improvements on the vector
3578 * gh.h (gh_vector): this used to exist but do the wrong thing.
3579 Now it (almost) does the right thing, though it takes a list
3580 instead of the individual arguments. I need to see how it could
3582 (gh_list_to_vector): added this function as a macro. Corresponds
3583 to Scheme's (list->vector ...).
3584 (gh_vector_to_list): added this function as a macro. Corresponds
3585 to Scheme's (vector->list ...).
3587 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3588 gh_vector_ref, so that it resembles the Scheme routines more.
3589 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3590 resembles the Scheme routines more.
3591 (gh_make_vector): this used to be (stupidly) called gh_vector().
3592 This is the right name, since it does the same thing as the Scheme
3593 (make-vector ...) procedure.
3595 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3597 * ports.h: #include "libguile/print.h"
3599 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3600 Some indentation fixes.
3602 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3603 longer a user field; New field: class_flags.
3605 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3607 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3609 * gh_data.c (gh_bool2scm): new function which replaces
3610 gh_int2scmb(), which is now tagged as obsolete.
3612 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3614 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3615 macros should by convention not test for NIMPness.)
3616 (SCM_COERCE_OPORT): Adjust indentation.
3618 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3619 SCM_NIMP test before SCM_PRINT_STATE_P.
3621 * struct.c, struct.h, gc.c: Renamed:
3622 scm_struct_i_layout --> scm_vtable_index_layout
3623 scm_struct_i_vcell --> scm_vtable_index_vcell
3624 scm_struct_i_vtable --> scm_vtable_index_vtable
3625 scm_struct_i_printer --> scm_vtable_index_printer
3626 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3628 * struct.c (scm_print_struct): Use new printer slot; Default
3629 printing: Also output hex code of vtable so that type identity
3630 will be indicated as well.
3631 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3632 Removed struct_printer_var; Removed struct-vtable-offset;
3633 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3634 vtable-offset-user): New constants.
3636 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3637 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3638 If this slot contains a procedure, use that to print structures of
3639 the type represented by this vtable.
3641 * print.c (scm_iprin1): Don't print arguments of macro
3642 transformers. (They are always: exp env.); Bugfix: Unmemoize
3643 transformer source with correct environment.
3645 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3647 Streamlining of call-with-dynamic-root:
3649 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3650 there is now only one catch.
3651 (cwdr_outer_body): Removed.
3652 (cwdr_handler): New function.
3653 (scm_internal_cwdr): New function to perform the function of cwdr
3654 but take args that are more useful to C code. Also, the handler
3655 is now invoked *outside* of the new dynamic root, like the docs
3656 say. We no longer have to catch absolutely all errors, the caller
3657 is responsible for using a handler that does not throw, if he
3659 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3660 * root.h (scm_internal_cwdr): New prototype.
3662 Even more but risky streamlining:
3664 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3665 allocation of the jumpbuf of a root continuation. The changes
3666 below are controlled by it. They are now deactivated.
3667 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3668 the JMPBUF of the scm_rootcont to NULL before returning.
3670 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3671 when they are non-NULL.
3672 (scm_gc_mark): Likewise, mark only when non-NULL.
3674 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3675 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3677 * gc.c (scm_done_malloc): New function.
3678 gc.h (scm_done_malloc): New prototype.
3680 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3681 (struct scm_print_state) [revealed]: New field.
3682 (scm_print_state_vtable): Make visible to the outside world for
3683 type checking purposes.
3684 (scm_valid_oport_value_p): New prototype.
3686 * print.c (scm_valid_oport_value_p): New function to check whether
3687 a certain value is acceptable as a port argument.
3688 (scm_print_state_vtable): New variable.
3689 (scm_free_print_state): Set `revealed' field to false.
3690 (scm_iprin1): Call user supplied closure printer with
3691 scm_printer_apply. Print in the traditional way when there isn't
3692 one or when it returns #f.
3693 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3694 Accept a port/print-state pair in addition to just a port.
3695 (scm_prin1): Don't return the print_state to the pool when it has
3697 (scm_printer_apply): Set `revealed' field of print_state to true.
3698 (scm_init_print): Set scm_print_state_vtable.
3699 (print_state_fluid, print_state_fluid_num): Removed.
3701 * throw.h (scm_handle_by_proc_catching_all): New prototype
3702 throw.c (scm_handle_by_proc_catching_all): New function
3704 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3706 * Makefile.in: Regenerated with automake 1.2c.
3708 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3710 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3711 was looping endlessly.
3713 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3715 * strports.c (scm_eval_string): Don't close the port.
3717 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3718 former returns a nice normal integer. (Thanks to Daniel
3721 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3723 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3724 makefile variable as a build parameter called LIBS. The
3725 build-guile program will use this, for the time being.
3726 * Makefile.in: Regenerated.
3728 Thanks to Shiro Kawai:
3729 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3730 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3733 * Makefile.in: Regenerated with automake 1.2a.
3735 * script.c (scm_compile_shell_switches): If we hit the -c or --
3736 arguments, don't set the car of (command-line) to scm_usage_name,
3737 the prettified name of the guile executable; give it the full
3738 path, the way shells usually handle $0.
3740 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3742 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3743 Scheme-level name `array-map' and renamed `serial-array-map' to
3744 `serial-array-map!'.
3746 * backtrace.c: Introduced exception handlers which now enclose
3747 `display-error' and `display-backtrace' so that error reporting
3748 won't get into infinite loops if an error occurs during displaying
3749 of the error. This can very easily happen with user supplied
3750 print call-back routines.
3752 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3754 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3755 the names `serial-array-map' and `array-map' should be removed.)
3757 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3759 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3760 Added #include "objects.h"
3762 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3763 Add #include "feature.h".
3765 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3766 (modinclude_HEADERS): Added objects.h.
3768 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3769 This test is needed at many places in the code and should be
3770 abstracted. (Motivated by the need of this test in libguiletk.)
3772 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3773 (scm_eval_string), load.c (scm_primitive_load,
3774 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3775 Use SCM_EOF_OBJECT_P.
3777 * eval.c (scm_init_eval): Add feature `delay'.
3779 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3781 * scmhob.h: Removed.
3783 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3785 * list.h (SCM_LISTn): New macros. Make list creation in C code
3786 prettier. The idea comes from STk.
3788 * sequences.h, sequences.c, append.h, append.c: Removed. These
3789 files implemented non-R4RS operations which would encourage
3790 non-portable programming style and less easy-to-read code.
3792 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3795 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3796 sequences.h, #include append.h.
3798 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3801 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3803 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3805 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3807 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3809 * eval.c: Added #include "objects.h"
3811 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3814 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3815 adjacent smob numbers.
3817 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3819 * procprop.h: Added declaration of scm_i_inner_name.
3821 * gsubr.c: New global symbol scm_i_inner_name.
3823 * debug.c (scm_procedure_name): Try procedure property
3824 `inner-name' if `name' fails.
3826 * print.c (scm_iprin1): Use scm_macro_name.
3828 * eval.c (scm_m_define): Give names to macros as well; Only the
3829 first top-level definition gives a procedure/macro a name.
3830 Otherwise confusing names can turn up in backtraces.
3831 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3832 `name'; Give names to macros as well.
3834 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3835 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3838 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3840 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3842 (prinmacro): Removed. The code has been moved/merged into print.c
3843 in order to decrease code redundancy. We want macros to print in
3844 a way equivalent to procedures, and it would be silly to duplicate
3845 the required code. (We don't want to maintain two places.)
3846 (macrosmob): Print field is now a NULL pointer.
3848 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3849 scm_macro_transformer): New prototypes.
3850 (scm_tc16_macro): Declared.
3852 * print.c (scm_iprin1): Added code for printing of macros. Macros
3853 are now printed in a way equivalent to procedures.
3855 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3857 * procs.h (scm_closure_p): Added declaration.
3859 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3861 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3862 Shouldn't pass "heap" as the subr name.
3864 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3866 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3867 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3868 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3869 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3870 SCM_BOOL_T. Any non-false value is true.
3872 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3874 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3875 scm_gensym): Added prototypes.
3877 * symbols.c (scm_gensym): New function. This will speed up
3878 certain types of applications (such as macro systems) which
3879 generate lots of symbols.
3881 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3883 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
3885 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
3887 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3888 specifier, since (2) or (2 . 3) would cause SEGV.
3889 (scm_transpose_array): more argument checking fixes.
3891 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
3893 * Makefile.in: Regenerated.
3895 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3897 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3899 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3901 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3903 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3905 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3906 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3909 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3910 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
3911 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
3912 scm_array_p, scm_array_rank, scm_array_dimensions,
3913 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
3914 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
3915 scm_array_prototype): Added case scm_tc7_wvect.
3917 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3919 * errno.h: prototype for scm_strerror.
3920 * error.c (scm_strerror): new procedure.
3922 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3924 * list.c (scm_list_append_x): Allow non-pair as last argument.
3925 This is consistent with the R4RS append and is probably the
3926 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3928 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3930 * stime.h: prototype for scm_times.
3931 * stime.c (scm_times): new procedure.
3932 * ioext.c (scm_fseek): if the first argument is a file descriptor
3934 (scm_ftell): if the first argument is a file descriptor call lseek
3936 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
3937 * filesys.c (scm_chmod): if the first argument is a file descriptor,
3939 (scm_chown): if the first argument is a port or file descriptor,
3941 (scm_truncate_file): new procedure.
3942 Add DEFER/ALLOW INTS to a few other procedures.
3943 (scm_fsync): new procedure.
3944 (scm_open_fdes): new procedure.
3945 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3947 (scm_fcntl): the first argument can now be a file descriptor. The
3948 third argument is now optional.
3950 * posix.c (scm_execl, scm_execlp): make the filename argument
3951 compulsory, since omitting it causes SEGV.
3952 (scm_sync): return unspecified instead of #f.
3953 (scm_execle): new procedure.
3954 (environ_list_to_c): new procedure.
3955 (scm_environ): use environ_list_to_c. disable interrupts.
3956 (scm_convert_exec_args): take pos and subr arguments and
3957 improve error checking.
3959 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3961 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3962 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3963 argument to SCM_ASSERT. Furthermore, the name of the function
3964 should be passed as first argument when signalling
3965 SCM_WNA. (Thanks to Thomas Morgan)
3967 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3968 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3969 dispatches on the number of actual args has a default case
3970 reporting an internal error. This is a vestige from a version
3971 that mallocated a SCM vector to hold the arguments. In the
3972 current version this check is too late: if it ever happens we will
3973 have already overstepped the bounds of the array.
3975 Also, the patch [...] adds a check for too many actual arguments."
3977 mdj: Removed check for "internal programming error".
3979 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3981 * gh_io.c (gh_write): New function.
3983 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3984 throw.c (scm_internal_stack_catch): New sibling to the other catch
3985 functions. Code moved from gh_eval.c.
3986 throw.h: Added header.
3987 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
3988 scm_internal_stack_catch.
3990 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3992 * ioext.h: fix up prototypes.
3993 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3994 Scheme name is now dup->fdes.
3995 (scm_dup_to_fdes): make the second argument optional and
3996 fold in the functionality of scm_primitive_dup.
3997 (scm_primitive_dup): deleted.
3999 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4001 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4002 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4003 ultrix are defined. Use setvbuf instead of setbuf.
4004 (scm_setvbuf): new procedure.
4005 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4006 (scm_setfileno): moved from ioext.c.

4044 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4065 * ioext.c (scm_primitive_dup2): return the new file descriptor
4066 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4068 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4069 stream has been set.
4070 (scm_duplicate_port): deleted, there's now an implementation in
4072 (scm_primitive_dup2): do nothing if newfd == oldfd.

4124 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4125 the dynamic object data below the linking of the object to avoid
4126 memory leak when the linking code throws an error. Now the code
4127 leaks a whole dynamically linked library when must_malloc throws,
4128 but that should be much less likely.
4130 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4132 Changes to compile under gnu-win32, from Marcus Daniels:

4144 * scmsigs.c (scm_pause): Don't include unless pause was found
4146 * posix.c (scm_getgroups): Don't include unless support function
4147 was found during autoconf (in this case, getgroups).
4148 (scm_setpwent): For setpwent.
4149 (scm_setegid): For setegid.
4150 * net_db.c (scm_inet_netof): Don't include unless support

4170 think this is left over from the (eq? '() #f) days.
4172 * read.c (recsexpr): Give this a dummy definition if
4173 DEBUG_EXTENSIONS isn't #defined.
4175 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4177 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4188 alloca.lo will be included in @LIBLOBJS@. Something better than
4189 this should be possible.

4192 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4194 * simpos.h: prototype for scm_primitive_exit.

4202 have to do this explicitly. Also, if regexp/basic is supplied, then
4203 turn off REG_EXTENDED.
4204 (scm_init_regex_posix): New regexp/basic symbol.
4205 (REG_BASIC): #define this if it is not already present.

4224 flag; I don't think we support it.
4225 (scm_make_regexp): Make sure the user doesn't pass the
4228 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4230 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4240 (versiondat.h): Print a message, but don't print all the commands.
4241 * load.c: #include "alist.h".
4242 (init_build_info): New function.
4243 (scm_init_load): Call it.

4248 * root.c: Establish a reliable catch-all handler for the new root.
4249 After all the Scheme handler function might signal an error too,
4250 and we don't want to lose that.
4251 (cwdr_inner_body): Renamed from cwdr_body.
4252 (cwdr_outer_body): New function, to establish the user's handler,
4253 and pass control to cwdr_inner_body.
4254 (cwdr): Establish the reliable catch-all handler here, and pass
4255 control to cwdr_outer_body.
4256 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4257 the user's handler through to cwdr_outer_body.

4261 * throw.h (scm_handle_by_message_noexit): New prototype.
4263 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4264 across this. Only works on GCC. Otherwise, we hope for the best.
4265 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4266 the feeling that real thread systems will not need this...
4268 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4270 Try to detect when people are using one version of libguile and a

4282 primitive definitions under their Scheme names.
4284 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4285 1:2. Helps avoid confusion between installed and uninstalled libs.
4287 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4290 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4291 backslash from definition; this should be used like: GDB_INTERFACE;
4293 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4295 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4296 new port unbuffered until its stream has been set.
4298 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4300 * ports.h: new prototype.
4301 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.

4307 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4308 unsigned, because that's what the ANSI function takes.
4309 * extchrs.h (xmbtowc): Corresponding change to prototype.
4310 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4312 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4313 argument plain char *.
4314 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4316 * tag.c (scm_tag): Remove unreachable statement.
4317 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4318 top of the word, it should be unsigned.
4320 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4321 is defined, to avoid warnings; it's only used in the
4322 conflict-checking code. Which might go away anyway.
4323 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4324 conditionals; put the label definition in an #if too, to stifle
4327 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4328 ChangeLog-threads in the distribution.
4329 * Makefile.in: Regenerated.

4333 * guile-snarf.in: Changed regexp to support CPPs that insert
4334 whitespace between lexical tokens (which munges the `%%%' snarf
4337 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4339 * load.c (scm_init_load_path): Append $(datadir)/guile to
4340 %load-path, so modules do not have to be installed in Guile's
4341 current version directory.
4343 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4345 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4346 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4347 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4348 call the sysdep functions with deferred ints.

4350 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4351 deferred interrupts and insert SCM_ALLOW_INTS before throwing an

4370 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4371 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4374 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4376 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4377 supplied. (Change from Tim Pierce.)
4379 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4381 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4382 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4383 default and not `()'. `#f' is the canonical non-value in Scheme,
4386 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4388 * struct.c (struct_printer): New variable that holds a handle on
4389 the Scheme variable *struct-printer*. This variable can be set by
4390 Scheme code to override the printing of structures.
4391 (scm_print_struct): If struct_printer is set, call it. If it is
4392 not set, or returns #f, print the structure in the old fashion.
4393 Include "eval.h" for scm_apply.
4395 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4397 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4398 scm_struct_i_n_words to get the number of fields, not
4399 -scm_struct_n_extra_words.
4401 On the route to fancier struct printing:
4402 * struct.c (scm_print_struct): New function to print a structure.
4403 Include "genio.h" to support it. This function doesn't do
4404 anything interesting right now, but I think it should be here
4406 * struct.h: Include "print.h" and add prototype for
4408 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4409 print structures ourself.
4411 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4413 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4414 before applying the handler in case it doesn't return.
4416 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4418 * scmsigs.h, async.h: updated.
4420 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4423 * posix.c (scm_uname): interpret only negative values as an error.
4424 Solaris normally returns a positive value.
4426 * script.c (scm_compile_shell_switches): if we are not going into
4427 an interactive repl, set scm_mask_ints to zero so that asyncs can
4430 * simpos.c (scm_system): don't ignore/unignore signals around
4433 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4436 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4437 done in boot-9.scm instead.
4439 * scmsigs.c, async.c: Major rewriting of signal handling code.
4440 (scm_sigaction): new procedure.
4441 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4443 (scm_raise): return unspecified, throw error on failure.
4445 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4447 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4448 feature, to help boot-9.scm decide whether to import the regex
4451 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4453 * eval.c: Include scmconfig.h at the beginning of the file so that
4454 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4457 * regex-posix.c: #include "_scm.h" before conditionally #including
4458 <regex.h>; the former defines HAVE_REGCOMP.
4460 * regex-posix.c: #include <regex.h> conditionally, so the file is
4461 CPP'able (for dependency scanning) even on systems that don't have
4464 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4466 Add new R4RS-compliant syntax for keywords.
4467 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4468 regardless of the setting of the `keywords' read option.
4469 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4470 can be re-read no matter what the setting of the `keywords' read
4473 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4475 Add support for POSIX regular expressions.
4477 * regex-posix.c, regex-posix.h: New files. (Some code
4478 is taken liberally from rx/rgx.c in the old Guile dist.)
4480 * init.c: Include regex-posix.h.
4481 (scm_boot_guile_1): Call scm_init_regex_posix.
4483 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4484 Add regex-posix.[ch] sources.
4485 * Makefile.in: Regenerated.
4487 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4488 to do this automatically? It didn't for me, bleh.)
4490 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4492 * fports.c (print_pipe_port): New function.
4493 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4494 latter doesn't even take the right arguments.
4496 * Makefile.am: Increment shared lib revision number. I think
4497 sometimes the uninstalled Guile finds the installed shared lib;
4498 Gord says doing this might help. As things turned out, I can't
4499 say whether it does.
4500 * Makefile.in: Regenerated.
4502 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4503 passing it as the closure argument to scm_boot_guile. (Bill
4506 * ports.c (print_void_port, putc_void_port, puts_void_port,
4507 write_void_port, flush_void_port, getc_void_port, close_void_port,
4508 noop0): Use ANSI prototypes instead of K&R declarations, so the
4509 initialization of void_port_ptob gets aggressively type-checked.
4510 Fix arguments of print_void_port and write_void_port. (Bill

4544 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4546 * script.c (scm_find_executable): Use prototype-style definition
4547 here; apparently it's not quite right to have const in a prototype
4548 and then use a K&R declaration. I wonder if stuff like this will
4549 go away if we compile with -Wrequire-prototypes, or whatever that
4550 is... (Bernard URBAN)
4552 * scmhob.h: New text from Bernard URBAN.
4554 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4556 * script.c: Don't #define const on hpux. Configure takes care of
4557 this. (Thanks to Larry Schwimmer.)
4559 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4560 decide whether to #include <unistd.h>, instead of listing a bunch
4561 of systems. Don't #include stdio twice. Removed dyked-out
4562 definition of scm_find_impl_file.
4564 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4566 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4567 library version info to 1:0.
4568 * Makefile.in: Regenerated.
4570 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4574 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4575 throw.c: Update copyright years; these files have been worked on
4576 significantly in 1997, but only had copyright years for 1996.
4577 Also, change name of copyright holder on some from Mikael
4578 Djurfeldt to Free Software Foundation; he has signed papers
4579 assigning the changes to the FSF.
4581 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4582 reason not to give the user the option.
4584 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4585 Return #f on end-of-file when scanning table (i.e. when called
4586 with no arguments). Try to catch errors, when we can.
4587 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4589 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4590 external declarations. These are useful.
4592 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4594 * posix.c: don't include <sys/select.h> or define macros for
4595 select, since they were not used in this file.
4597 * filesys.c (scm_select): make the fifth parameter microseconds,
4598 not milliseconds. let the fourth parameter be either a real value
4599 or an integer or #f. The first, second and third arguments can
4600 now be vectors: the type of the corresponding return set will be
4602 (set_element, get_element): new static procedures.
4604 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4606 * strports.c (scm_eval_string): New function.
4607 (scm_eval_0str): Trivially re-implemented in terms of
4609 * strports.h (scm_eval_string): New extern decl.
4611 * net_db.c (h_errno): Add extern decl for this.
4613 * fports.c (local_pclose): New function.
4614 (scm_pipob): Use it in the initializer here.
4617 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4618 Use a meaningful error message when signalling an error. For
4619 this, scm_gethost must check h_errno rather than errno.
4621 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4623 * Makefile.in: Regenerated, using automake-1.1p.
4625 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4627 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4628 not SCM_UNSPECIFIED.
4630 * script.c (scm_compile_shell_switches): don't append (quit) if
4632 (scm_shell): call scm_exit_status and exit on the result of the
4635 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4637 Ensure that shared substrings are handled properly when passed to
4638 a system call or other foreign function. Many thanks to Tim
4640 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4641 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4642 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4643 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4644 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4645 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4646 (scm_display_error_message): use RO macros when strings may be RO.
4647 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4648 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4649 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
4650 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
4651 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
4652 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
4653 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4654 scm_strftime), vports.c (scm_make_soft_port): use
4655 SCM_COERCE_SUBSTR to make sure shared substrings are
4658 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4660 * error.c (scm_error): Add newline to error message.
4662 * init.c (scm_init_standard_ports): Doc fix.
4664 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4666 * dynl-shl.c: Completely replaced with new code from Bernard
4669 * script.c (scm_ice_9_already_loaded): New variable.
4670 (scm_compile_shell_switches): Use it.
4672 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4674 * filesys.c (scm_input_waiting_p): add missing third argument to
4677 * stime.c (scm_localtime): copy the result of localtime before
4678 calling gmtime in case they share a buffer.
4679 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4682 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4684 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4686 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4688 * Makefile.am (check-local): New target, which causes 'make check'
4689 to run gh_test_c and gh_test_repl, with some trivial input.
4690 * Makefile.in: Rgnrtd.
4692 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4694 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4697 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4699 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4700 sure how this was supposed to work.
4701 (scm_async_click): don't send SCM_TICK_SIGNAL.
4702 (scm_init_async): don't initialize %tick-thunk.
4704 * the following change doesn't affect the Scheme interface:
4705 gc-thunk is called at the end of garbage collection. however it's
4706 no longer implemented by pretending it's a signal.
4708 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4709 system async corresponding to scm_gc_thunk.
4710 * async.h: declare scm_gc_async.
4711 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4712 gc-thunk directly, instead of going through a signal handler.
4713 (scm_gc_async): new variable, points to the GC system-async.
4714 (scm_init_async): save the GC async as scm_gc_async instead
4715 of using system_signal_asyncs.
4716 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4718 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4720 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4721 Don't screw up if we're interrupted.
4722 * Makefile.in: Regeneradet.
4724 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4726 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4728 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4729 we're not using AM_INIT_GUILE_MODULE any more.
4730 * Makefile.in: Reneregated.
4732 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4734 Functions for finding variable bindings, grace à Tim Pierce.
4735 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4736 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4738 Get 'make dist' to work again.
4739 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4740 * Makefile.in: Regenerated, like a surry without a fringe on top.
4742 Changes for reduced Guile distribution: one configure script,
4744 * configure.in, configure: Removed.
4745 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4746 real configure script lives.
4747 * Makefile.in, scmconfig.h.in: Regenerated.
4749 * init.c: #include "script.h", to get prototype for script.c's
4752 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4754 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4755 scm_must_malloc, not raw malloc.
4757 * script.c (scm_compile_shell_switches): Dyke out debugging output
4760 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4762 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4764 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4765 system has them. Hope this is safe. Previously
4766 sys/timeb.h was included if HAVE_FTIME was defined or if
4767 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4768 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4770 * ioext.c (scm_setfileno): add missing third argument to
4771 scm_misc_error call.
4773 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4775 * eq.c (scm_equal_p): Correctly compare strings of different
4776 varieties. (Thanks to Tim Pierce.)
4778 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4780 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4781 #! block comment must occur on a line all by itself.
4783 Move most of the guts of shell command processing into libguile,
4784 so guile.c can be very small (and eventuallly auto-generated. (I
4785 mean, generated mechanically, not self-generated. Hmm.))
4786 * guile.c, script.c, script.h: New source files.
4787 * init.c (scm_boot_guile_1): Call scm_init_script.
4788 * libguile.h: #include "script.h".
4789 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4790 targets, for new executable.
4791 (libguile_la_SOURCES): Mention script.c.
4792 (modinclude_HEADERS): Add script.h.
4793 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4794 not dynamic linking is enabled. This is because we're generating
4795 executables now. Move CY_AC_WITH_THREADS call after those, so the
4796 values of cy_cv_threads_libs captures the libs chosen above.
4797 * Makefile.in, configure, aclocal.m4: Regenerated.
4799 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4800 We don't maintain this interface any more, and it just confuses
4803 * alloca.c: #include <scmconfig.h>, not <config.h>.
4804 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4805 it'll get included in disties.
4807 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4809 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4810 be distributed, because they confuse people.
4811 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4813 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4815 * configure.in: check for presence of gethostent (not present on
4816 OpenBSD by default).
4817 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4818 * configure, scmconfig.h.in: Regenerated.
4820 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4822 * backtrace.c (scm_backtrace): Split message string across
4823 newlines properly. GCC is more tolerant of this than other
4826 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4828 Merge threads directory into libguile.
4829 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4830 threads.h: New source files.
4831 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4832 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4834 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4835 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4836 coop-threads.c.cygnus, coop-threads.h.cygnus.
4837 * configure.in: If we're using threads, include threads.o in
4839 * _scm.h, libguile.h: threads.h lives in this directory now.
4840 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4841 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4842 currently used, but brought along for information's sake.
4843 * ChangeLog-threads: log from old 'threads' directory.
4844 * Makefile.in, configure: Rebuilt.
4846 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4848 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4851 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4853 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4855 Merge GH interface library into libguile.
4856 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4857 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4858 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4859 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4861 (EXTRA_libguile_la_SOURCES): ... here.
4862 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4863 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4864 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4865 New variables, describing how to build the gh test programs.
4866 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4867 build the test programs, and we probably should have been linking
4868 libguile.la against them all along, to support AIX shared libs.
4869 Add cflags for threads to CFLAGS; add libs for threads to new
4870 variable THREAD_LIBS, used in Makefile.am.
4871 * ChangeLog-gh: log from old `gh' subdirectory.
4872 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4874 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4876 * acconfig.h: Undo change of Apr 9; including the definition of
4877 PACKAGE in the guile headers conflicts with applications' own
4879 * scmconfig.h.in: Regenerated.
4881 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
4883 * filesys.c (scm_fcntl): New function from Roland McGrath.
4884 (scm_init_filesys): New symbols for use with fcntl.
4885 * filesys.h: Added prototype.
4887 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
4888 when PROC is receiving no arguments.
4890 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4892 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4893 have S_IFSOCK. This is the case under Ultrix.
4895 * posix.c (scm_status_exit_val, scm_status_exit_val,
4896 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4897 Ultrix versions of WIFSTOPPED, etc., which assume that their
4898 arguments are lvalues (hmm).
4900 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4902 * eval.c: Doc fixes.
4904 * throw.c: Doc fixes; rearranged.
4906 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
4908 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
4910 * acconfig.h: Added entry for PACKAGE.
4911 * scmconfig.h.in: Regenerated.
4913 Changes to work with automake-1.1n, which has better libtool support.
4914 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4915 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
4917 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
4919 * Makefile.in: Rebuild.
4921 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4923 * stime.c (scm_mktime): take an optional zone argument.
4924 (scm_localtime): check putenv return value.
4925 (scm_strftime, scm_strptime): moved from posix.c. move #include
4927 stime.h, posix.h: update prototypes.
4928 (bdtime2c, setzone, restorezone): new static procedures.
4929 (scm_mktime, scm_strftime): use them.
4930 (scm_strftime): don't call mktime before strftime. Use
4931 filltime for return value.
4932 (filltime): convert NULL zname to #f.
4933 (scm_strptime): return a count of characters consumed, not
4934 the remaining string.
4936 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4938 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
4939 (scm_mktime): likewise.
4941 Uncomment localtime and mktime.
4943 * configure.in: add AC_STRUCT_TIMEZONE.
4945 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4947 * stime.c (scm_init_stime): don't define ticks/sec.
4948 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4949 return value problem and is still portable.)
4951 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4953 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4954 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4955 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4956 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4957 cpp_err_symbols.c): Corresponding changes.
4958 * Makefile.in: Regenerated.
4960 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4962 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4963 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4964 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4965 * putenv.c: new file, from sh-utils 1.12.
4967 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4968 since allocation isn't for Scheme objects.
4969 (scm_putenv): copy strings before placing in the environment.
4971 * stime.c (scm_current_time): throw an error if time returns -1,
4972 instead of returning #f.
4973 (scm_get_internal_real_time, scm_get_internal_real_time): use
4974 scm_long2num for return value instead of SCM_MAKINUM.
4976 * stime.h: prototypes updated.
4978 * stime.c (scm_time_in_msec): apparently unused, deleted.
4980 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4982 * configure.in: check for gettimeofday.
4984 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4985 which may be more usefully portable than a gettimeofday interface.
4987 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4989 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
4991 * Makefile.in: Regenerated.
4993 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4995 * stime.c (filltime): recovered static procedure.
4996 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4999 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5000 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5002 * posix.c (scm_mknod): split the mode argument into type and perms
5003 arguments, like the extra fields returned by stat.
5005 * fports.c (scm_pipob): set the close, free and print procedures.
5006 (scm_close_pipe): new procedure.
5008 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5009 define them in boot-9.scm
5011 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5013 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5014 wan't defined. Don't include fd.h.
5016 * Previously fd.h was regenerated whenever configure was run,
5017 forcing a couple of files to be recompiled.
5019 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5020 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5021 Check for _fileno as well as _file.
5023 * ioext.c: don't fd.h.
5024 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5027 * Change the stratigy for getting information about errno
5028 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5029 generating lists of symbols during the build process, which will
5030 not always work, include comprehensive lists in the distribution.
5031 To help keep the lists up to date, the "check_signals" and
5032 "check_errnos" make targets can be used.
5034 * configure.in: don't check for a command to extract errno codes.
5035 * Makefile.am: update file lists, remove errnos.list and errnos.c
5036 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5037 check_errnos targets.
5038 (CLEANFILES): remove errnos.c and errnos.list, add
5039 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5040 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5041 * errnos.default: deleted.

5045 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5046 * error.c (scm_init_error): #include cpp_err_symbols instead of
5048 * posix.c (scm_init_posix): don't intern signal symbols. #include
5051 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5053 * strop.c (scm_i_index): allow the lower bound to be equal to the
5054 length of the string, so a null string doesn't always give an error.
5056 * posix.h: new prototypes.
5057 * posix.c (scm_status_exit_val, scm_status_term_sig,
5058 scm_status_stop_sig): new functions, as in scsh. They break down
5059 process status values as returned by waitpid.
5061 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5063 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5064 configure doesn't know about it.
5066 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5068 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5070 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5071 which defines C variables with global linkage.
5073 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5075 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5078 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5080 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5081 has time to check why this doesn't work well with continuations.
5083 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5085 * Fix shell syntax error; some shells won't tolerate
5086 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5088 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5090 * posix.c (scm_uname): throw an error if uname fails instead
5093 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5095 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

5100 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5102 * acconfig.h: Removed PACKAGE.
5104 * scmconfig.h.in: Regenerated.
5106 * snarf.h: g++ says it's non-portable not to specify the first
5107 argument in a varargs declaration. I introduced the first
5108 argument by using preprocessor conditionals.
5110 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5112 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5113 (scm_freopen): use RO string macros for filename and modes.
5114 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5116 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5117 (scm_mknod): use RO string macros for path.
5119 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5120 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5122 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5123 use SCM_ROSTRINGP and SCM_ROCHARS.
5125 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5127 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5130 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5131 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5132 support for byte vectors.
5134 * print.c (scm_iprin1): Limit number of vector elements printed
5135 according to pstate->length.
5137 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5139 * backtrace.c (scm_display_error_message): don't segv if message
5142 * error.h: prototype for scm_error_scm.
5144 * error.c (scm_error_scm): new procedure, reimplements scm-error
5145 in C and uses scm_error.
5147 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5149 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5150 pointer to the Scheme variable read-hash-procedures and intern it
5151 in scm_init_read. Modify scm_read_hash_extend and
5152 scm_get_hash_procedure to use the pointer.
5154 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5156 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5157 (SCM_KEYWORD_STYLE): defined.
5159 * read.c (scm_read_opts): add a keywords option. This isn't a
5160 boolean option, in case someone wants to add support for DSSSL
5162 Setup scm_keyword_prefix symbol.
5163 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5165 I've left keyword support disabled by default, since it doesn't
5166 seem to break the module system and it gives R4RS standard behaviour.
5167 It can be reactivated with (read-set! keywords 'prefix).
5169 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5171 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5172 before constructing arbiter.
5174 * eval.c (scm_m_define): Bugfix: Check that the object is a
5175 closure before setting the procedure property!
5177 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5179 * ports.c: Removed `ungetc-char-ready?'.
5181 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5183 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5184 (idea from Mikael: make it a pair so scm_permanent object only
5186 (scm_read_hash_extend): don't call scm_permanent_object.
5187 (ideas from Mikael): if chr is already in the list, replace its
5188 procedure instead of appending it again. If proc is #f, remove
5190 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5192 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5194 * gdbint.c (gdb_read): update scm_lreadr usage.
5196 * load.h: update prototypes.
5198 * load.c (scm_primitive_load, scm_read_and_eval_x,
5199 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5201 * read.h: add prototype for scm_read_hash_extend. Change args for
5204 * read.c (scm_read_hash_procedures): new variable.
5205 (scm_read_hash_extend): new procedure.
5206 (scm_get_hash_procedure): new procedure.
5207 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5208 for extended # processing.
5209 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5210 scm_read_token): remove case_i, sharp arguments. Change callers.
5212 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5214 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5215 (SCM_CASE_INSENSITIVE_P): define.
5217 * read.c: add case-insensitive option to scm_read_opts.
5218 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5219 to determine whether to convert symbol case.
5220 (default_case_i): definition removed.
5221 * read.c (scm_read_token): if case_i, downcase ic before doing
5224 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5226 * configure.in: Added configuration option `guile-debug'.
5227 Configure with --enable-guile-debug if you want a bunch of extra
5228 functions used for debugging when developing Guile.
5230 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5232 * procs.c (make-cclo): New undocumented debugging procedure: Make
5233 compiled closure with internal procedure PROC and length LENGTH.
5234 Only compiled if GUILE_DEBUG is defined.
5236 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5238 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5240 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5242 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5243 with 3 or more args internally to the evaluator.
5245 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5247 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5248 with 3 or more args internally to the evaluator. This is mainly
5249 because we don't want to pass entry and exit points of the
5250 debug support twice, but it also seems to increase the speed of
5251 the evaluator for such calls (e. g. (+ 1 2 3)).
5253 * backtrace.c (scm_display_application): New procedure:
5254 display-application; Set fancy printing parameters individually
5255 for different types of display (backtrace, error, application).
5256 (These should of course be customizable!)
5258 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5259 clear the CHECK-flags.
5261 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5263 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5265 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5267 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5268 from pairs with a GLOC in the car.
5270 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5271 otherwise `symbol-hash' will behave badly.
5272 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5273 we get segmentation fault!
5275 * symbols.c: Added #include "weaks.h". New functions:
5276 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5277 moved to an extraneous library when we split libguile.)
5279 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5281 * filesys.c (scm_stat): stat now takes fport arguments too as
5282 documented in the manual.
5284 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5286 * debug.c (scm_single_step): Bugfix: Call continuation with
5287 scm_call_continuation instead of throwing to it.
5289 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5291 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5292 argument wasn't declared to be optional.
5294 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5296 * stime.c (scm_init_stime): Add feature "current-time".
5298 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5300 * throw.h: prototype for scm_exit_status.
5301 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5302 args to derive an exit status. Allows (quit) to work from a
5304 (scm_exit_status): new function.
5307 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5309 * eval.c (scm_deval): Removed some old code.
5310 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5312 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5315 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5318 * procs.c: Introduce the existent C function scm_thunk_p at the
5319 Scheme level as well.
5321 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5323 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5324 used from C to easily lookup the value of a symbol in the current
5327 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5329 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5330 scm_init_unif in this file. This will also fix a previous problem
5333 * configure.in: Added AM_MAINTAINER_MODE
5335 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5337 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5340 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5342 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5343 source files that are not always included in libguile but should
5344 have their dependencies calculated by automake. This variable is
5345 recognized by automake, no further magic is needed.
5346 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5347 to deal exclusively with *.lo files, as it seems. The *.o files
5348 are built automatically when the corresponding *.lo file gets
5351 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5353 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5356 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5358 * unif.c (scm_array_set_x): minor change to argument error checking.
5360 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5362 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5363 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5364 They should only be included in the library at configure.in's
5366 (libguile_la_LDADD): Include the appropriate .lo files here.
5367 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5368 so we know when to build them (and their .lo bretheren).
5369 * configure.in (LIBLOBJS): New substituted variable. We let
5370 configure decide which .o files to include in LIBOBJS, and then
5371 put the corresponding list of .lo files in LIBLOBJS. The latter
5372 is what we pass to libtool.
5373 * Makefile.in, configure: regenerated.
5375 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5377 * symbols.c (scm_sysintern0): New function. Contains the core of
5378 old scm_sysintern but doesn't take a second value argument.
5379 (scm_sysintern): Now uses scm_sysintern0.
5380 (scm_sysintern_no_module_lookup): Renamed to
5381 scm_sysintern0_no_module_lookup and doesn't take a second value
5382 argument any longer.
5384 * symbols.h (scm_sysintern0: Added declaration.
5386 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5387 scm_sysintern when interning option keys. Otherwise we risk
5388 destroying the values of already interned variables.
5390 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5391 scheme-level boolean (use SCM_NFALSEP).
5393 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5395 (scm_backtrace): New function. (C version of old function from
5396 boot-9.scm) Motivation: Make it possible to display backtraces
5397 without depending on boot-9.scm. (I'm uncertain if this
5398 motivation is good enough...)
5400 * root.h (scm_root_state): Add member the_last_stack_var.
5401 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5403 * root.c (mark_root): Mark scm_the_last_stack_var.
5405 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5408 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5410 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5411 1. mark_lazy_catch didn't mark the smob.
5412 2. Both functions above have standard variants:
5413 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5414 free_lazy_catch --> scm_free0.
5416 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5418 * throw.c (scm_internal_lazy_catch): New function.
5419 (scm_lazy_catch): Rewritten to use it.
5420 (scm_ithrow): Handle the new lazy catch representation.
5421 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5422 that doesn't have a jmpbuf is a lazy catch clause.
5423 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5424 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5425 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5427 (scm_init_throw): Register the new lazy-catch smob type.
5428 * throw.h (scm_internal_lazy_catch): decl for new function.
5430 * throw.c (scm_internal_catch): Doc fixes.
5432 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5433 configure.in. Including this might cause problems if applications
5434 that link against libguile include their own copies of alloca, but
5435 if they're using autoconf, they should be adding libguile to LIBS
5436 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5437 the copy in libguile, and things will be okay. (I think.)
5439 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5441 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5443 strop.h: move prototypes too.
5445 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5447 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5450 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5451 etc. I deleted them from filesys.c long ago, but didn't
5452 notice they were here too (although ineffective since
5453 sys/stat.h wasn't included).
5455 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5457 * eval.c: Don't define alloca in GCC case. gcc will automatically
5458 use __builtin_alloca if appropriate.
5460 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5462 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5463 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5464 that values of automatic variables are preserved. See comments
5465 for safe_setjmp for details.
5467 Change from Thomas Morgan:
5468 * variable.c: Include eq.h.
5469 (var_equal): New function.
5470 (variable_smob): Use var_equal as the discriminator for variables.
5472 * throw.c (s_throw): Remove extraneous declaration.
5474 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5475 * eval.c: Add necessary CPP cruft to support that.
5476 * configure, Makefile.in, scmconfig.h.in: regenerated.
5478 Change from Thomas Morgan:
5479 * procprop.c (scm_procedure_properties): Convert the Scheme
5480 boolean returned by scm_procedure_p into a C boolean before using
5481 it as a condition for SCM_ASSERT.
5482 (scm_procedure_property): Likewise.
5484 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5485 indications of Unixness.
5488 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5490 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5492 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5494 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5495 "unknown # object" error messages.
5497 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5498 (scm_i_index) and declare it static. Add a 'direction' argument
5499 to indicate what way the search should go.
5500 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5502 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5503 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5505 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5507 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5509 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5510 to avoid clash with various scsh forks.
5512 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5514 The following two changes (ramap.c, throw.c) are motivated by the
5515 apparent unportability of forward declarations of static arrays of
5516 the form `static foo bar[];'.
5518 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5519 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5521 * throw.c (scm_throw): Moved above scm_ithrow.
5523 * options.h: Removed the extern declarations of scm_yes_sym and
5524 scm_no_sym since these are static.
5526 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5528 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5530 * Makefile.am: remove AWK=@AWK@.
5531 Add a rule for generating errnos.list.
5532 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5534 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5535 don't extract errnos, just set a variable (avoids the
5536 need to recompile error.c just because configure is run.)
5538 * unif.h: update prototypes.
5539 * unif.c (scm_uniform_array_read,write): change the offset and
5540 length arguments to start and end, for consistency.
5542 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5544 * ioext.h: update prototypes.
5545 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5546 scm_read_line_x, it's a more general procedure using an
5547 interface from scsh. read-line and read-line! are now defined
5549 Note that the new read-line trims the terminator
5550 by default, previously it was appended to the returned string. An
5551 optional argument specifies how to process the terminator (scsh
5552 compatible). For the old behaviour: (read-line port 'concat).
5553 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5554 returns a pair, but is converted to multiple values if the scsh
5557 socket.h: update prototypes.
5558 * socket.c (scm_recvfrom): for consistency with other procedures,
5559 take start and end as separate optional arguments.
5560 (scm_recv, scm_recvfrom): don't allow the second argument
5561 to be a size, only a buffer. Change the scheme names to
5562 recv! and recvfrom!. Don't return the buffer.
5564 * ioext.h, posix.h: move prototypes too.
5565 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5566 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5567 "read.h" and "unif.h".
5568 * ioext.c: include "chars.h"
5570 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5572 * dynl.c: The dynamic linking and module registration functions
5573 are now defined even when dynamic linking is not available for the
5574 host system. Some of their functionality can be done without
5575 dynamic linking; when it's really needed, they throw errors.
5577 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5579 * configure.in: Only define DYNAMIC_LINKING when one of the system
5580 dependent functions is detected.
5581 * dynl.c (scm_dynamic_func): New function to get the address of a
5582 function in a dynamic object.
5583 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5584 produced by scm_dynamic_func as the thing to call.
5586 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5588 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5589 (scm_register_module_xxx, scm_registered_modules,
5590 scm_clear_registered_modules): New functions.
5592 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5594 * symbols.c (scm_sysintern): Renamed to
5595 scm_sysintern_no_module_lookup.
5596 (scm_sysintern): New function to take the place of the old
5597 scm_sysintern. It uses the current toplevel lookup closure to give
5598 the symbol its value. This is a temporary hack to put packages
5599 like gtcltk into their own module.
5600 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5601 us whether `scm_top_level_lookup_closure_var' has been initialized
5603 * eval.c (scm_init_eval): Set it.
5605 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5607 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5608 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5610 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5612 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5613 scm_sys_dup): deleted: FD capability will be added to other
5615 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5616 scm_fd_free, fd_smob, scm_intern_fd.
5617 (scm_open): renamed from scm_sys_open. Return a port instead of
5618 an FD object. Make the mode argument optional.
5619 (scm_sys_create): deleted, it's just a special case of open.
5620 (scm_init_filesys): move interning of constants O_CREAT etc.,
5621 here (were previously using SCM_CONST_LONG macro).
5622 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5624 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5625 include "fports.h" and <stdio.h>
5626 (scm_stat, scm_select): don't support FD objects.
5628 * error.h: adjust scm_syserror_msg prototype.
5629 * error.c (scm_syserror_msg): take an extra argument for errno.
5630 Using the global value didn't always work, since it could be
5631 reset by procedure calls in the message or args arguments.
5633 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5634 I don't understand why the check was there (and what about the
5637 * strop.c (scm_string_copy): allow shared substrings to be copied.
5639 * unif.h: corresponding change to prototypes.
5640 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5641 recognize two new optional arguments: offset and length. Allow
5642 the port argument to be an integer (file descriptor, for scsh).
5643 Include <unistd.h> for "read" prototype.
5645 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5647 * socket.c: don't include filesys.h.
5649 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5651 * Makefile.am: add AWK=@AWK@ (?)
5653 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5655 Add a rule to generate errnos.c from errnos.
5656 * error.c (scm_init_error): include errnos.c.
5657 * errnos_cnvt.awk: new file, converts the list of errno codes to
5659 * errnos_get.c: new file.
5660 * errnos.default: new file, contains errnos to try if they can't
5661 be extracted from errno.h.
5662 * configure.in: if using GCC, try and extract errno codes from
5666 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5668 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5669 * Makefile.am: Made libguile into a libtool library.
5670 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5671 Set libtool_libs to indicate that libguile is a libtool library.
5672 See guile/ChangeLog for details.
5673 * .cvsignore: ignore "*.lo", the libtool library objects.
5675 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5677 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5678 use htons in getservbyport argument.
5680 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5682 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5683 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5686 * objprop.c (scm_object_property): No need to take the CDR of the
5687 value returned by scm_object_properties, since Aug 20 change.
5689 * configure.in: When checking for struct linger, #include
5690 <sys/types.h> as well as <sys/socket.h>. I've never known
5691 <sys/types.h> to cause any portability problems, and Solaris's
5692 <sys/socket.h> needs it.
5693 * configure: Rebuilt.
5695 I think the Sun compiler has chosen a perverse way to interpret
5696 ANSI declarations combined with K&R definitions. We'll
5697 appease it a little bit. But when it invades France, we fight.
5698 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5699 * print.h (scm_iprlist): Here too.
5700 * numbers.c (scm_divbigdig): Change definition to match
5701 declaration in numbers.h.
5702 * unif.c (scm_makflo): Change definition to match declaration in
5705 * init.c (scm_boot_guile): Don't return the value of
5706 scm_boot_guile_1. This function doesn't return a value;
5707 scm_boot_guile_1 doesn't return a value (or return at all).
5709 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5712 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5713 compile. I have a feeling this function is a bad idea anyway ---
5714 one should always test for features, not systems.
5716 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5717 semicolons. Only pure luck kept this from being noticed earlier.
5719 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5721 * socket.c (scm_recvfrom): Added missing semicolon.
5723 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5725 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5726 the buffer and start and end positions for scsh networking
5729 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5731 * configure.in: Revert previous change to this file; the problem
5732 is due to transient automake weirdness.
5733 * configure: Rebuilt.
5735 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5736 PLUGIN/guile.libs. configure generates the latter from the former.
5737 * Makefile.in: Rebuilt.
5739 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5740 need this if we install scripts, like guile-snarf.
5741 * configure: Rebuilt.
5743 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5745 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5747 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5749 * socket.c (scm_addr_vector): fix faulty scm_listify.
5751 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5753 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5754 style block comment is no longer considered an error.
5756 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5758 * PLUGIN/guile.libs.in: New file.
5759 * PLUGIN/guile.libs: Removed from repository.
5760 * configure.in: Create PLUGIN/guile.libs from
5761 PLUGIN/guile.libs.in. This is for including additonal libraries
5762 needed for dynamic linking.
5763 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5764 instead of PLUGIN/guile.libs.
5766 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5768 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5770 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5771 occurrences of the given element from the list, not just the
5772 first. This is how the Emacs Lisp functions behave, how the
5773 analogous Common Lisp functions behave, and (I believe) how the
5774 older Maclisp functions worked. I realize that this change may
5775 break code, but it seemed better to break it before the Guile
5778 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5779 Their prototypes were already present in gc.h, but they weren't
5781 (scm_init_storage): Initialize scm_protects.
5782 * root.c (scm_protects): New element of scm_sys_protects.
5784 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5786 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5788 * libguile.h: Added #include "libguile/net_db.h".
5790 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5791 30 change. That file is only meant for communication between the
5792 configuration process and load.c. If code linked against libguile
5793 wants to get at the paths mentioned in libpath.h, it can call
5794 functions declared in load.h.
5796 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5798 * libguile.h: Removed #include "libguile/fdsocket.h"
5800 * net_db.c: Added #include <sys/socket.h>.
5802 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5804 * filesys.c (scm_input_waiting_p): use select in preference to
5805 FIONREAD, since the latter doesn't detect EOF.
5806 Throw error if neither select nor FIONREAD available.
5808 * socket.c (scm_connect): take a port, not a fd object.
5809 (scm_fill_sockaddr): throw an error if fam is not recognised.
5810 (scm_bind): use scm_fill_sockaddr.
5811 (scm_listen): take a port, not a fd object.
5812 (scm_accept): take and return a port. return #f in the car if
5813 address can't be got
5814 (scm_sock_fd_to_port): new procedure.
5815 (scm_socket): use scm_sock_fd_to_port.
5816 (scm_addr_vector): throw error if unrecognised address type.
5817 take an extra argument with the calling procedure name.
5818 (scm_getsockname): take a port. return #f if address can't be got.
5819 (scm_getpeername): take a port. return #f if address can't be got.
5820 (scm_recvfrom): take a port. return #f for address component if can't
5822 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5823 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5825 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5827 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5828 use separate data pointers, to allow them to be designed
5829 independently and reused.
5830 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5831 Renamed from catch_body, catch_handler, and uncaught_throw; made
5833 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5835 (scm_catch): Use the above.
5836 (scm_throw): Don't bother printing a message for an uncaught
5837 throw; we establish a default handler in init.
5838 * throw.h (scm_internal_catch): Prototype updated.
5839 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5841 (struct scm_body_thunk_data): New structure, used as data
5842 argument to scm_body_thunk.
5843 * init.c (struct main_func_closure): New structure, packaging up
5844 the data to pass to the user's main function.
5845 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5846 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5847 scm_internal_catch to establish a catch-all handler, using
5848 scm_handle_by_message. This replaces the special-case code in
5850 (invoke_main_func): Body function for scm_internal_catch; invoke
5851 the user's main function, using the main_func_closure pointer to
5852 decide what to pass it.
5853 * root.c (struct cwdr_body_data): Remove handler_proc member.
5854 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5855 (cwdr_handler): Removed.
5857 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5859 * socket.h (SCM_P): update bind prototype.
5860 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5861 include "feature.h".
5862 (scm_socket): return a port, not a file descriptor object.
5863 include "fports.h" and <unistd.h>
5864 (scm_bind): take a port, not a file descriptor object.
5865 take an extra argument for address args.
5867 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5868 INADDR_NONE, INADDR_LOOPBACK.
5870 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5872 * init.c: include net_db.h and not fdsocket.h.
5873 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5875 * Makefile.am: corresponding changes.
5876 * socket.h: renamed from fdsocket.h, fix names.
5877 * net_db.h: renamed from socket.h, fix names.
5878 * socket.c: renamed from fdsocket.c.
5879 remove _sys from procedure names.
5880 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5881 add "socket" to features list.
5882 * net_db.c: renamed from socket.c.
5883 remove _sys from procedure names.
5884 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5885 add "net-db" to features list.
5886 include "net_db.h". don't include <sys/socket.h> or
5889 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5891 * tags.h (scm_tags): Removed comma at end of last enumerator.
5893 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5895 Don't use GCC extensions to allocate space for debugging frames.
5896 (Here he goes again! Why do we put up with this?!)
5897 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5898 an scm_debug_info structure, not an in-line array of them. Add
5899 'info' member, to say how many vect elements we've used, for eval
5901 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5902 a new variable debug_info_end to mark the end of vect, instead of
5903 the address of the 'info' pointer itself.
5904 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5905 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5906 (SCM_APPLY): Explicitly allocate space for debug.vect.
5907 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5908 * stacks.c: Adjusted for new debug frame structure.
5909 (RELOC_INFO, RELOC_FRAME): New macros.
5910 (stack_depth, read_frames): Use them, and new scm_debug_frame
5911 element 'info', instead of magically knowing that eval frames have
5912 an info pointer sitting after vect.
5913 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5915 (scm_init_stacks): Formatting tweaks.
5917 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5919 Give GCC more control flow information, so it can be sure that
5920 variables aren't used uninitialized.
5921 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5922 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5923 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5924 scm_misc_error): Tell GCC that these functions never return.
5925 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5926 out the field type, call abort if SCM_ASSERT returns, to placate
5928 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5929 scm_wta ever returns. We can't handle this case anyway, and this
5930 gives the optimizer more information.
5931 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5932 scm_wta ever returns.
5934 In some cases, the code is fine, but GCC isn't smart enough to
5935 figure that out; this usually happens when one variable is only
5936 initialized and used when a particular condition holds true, and
5937 we know that condition will never change within a given invocation
5938 of the function. In this case, we simply initialize the variables
5939 to placate the compiler, hopefully to a value which will cause a
5940 crash if it is ever actually used.
5941 * print.c (scm_iprin1): Initialize mw_pos.
5942 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5943 * throw.c (scm_ithrow): Initialize dynpair.
5944 * unif.c (scm_uniform_vector_ref): Initialize cra.
5945 * struct.c (init_struct): Initialize prot.
5946 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5948 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5949 if EXPR contains no expressions.
5951 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5953 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5954 cause an infinite loop (???). So much for the algebraic
5955 equivalency of variable-sized arrays and alloca...
5957 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5959 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5960 a SCM boolean, not a C boolean.
5962 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5964 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5965 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5966 rules for raising scm_mtrigger. Previously, unfortunate but not
5967 unlikely circumstances could result in almost constant invokation
5968 of the gc. Now, this situations should be less likely, but they
5969 are not prevented completely.
5971 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5973 * numbers.c (scm_fuck): Procedure removed; looks like old test
5975 * numbers.h: Prototype removed.
5977 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5979 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5980 array to a pointer, to match my Nov 21 change in eval.c.
5982 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5984 * libguile.h: Added #include "libguile/backtrace.h", #include
5985 "libguile/stacks.h".
5987 * strings.c (scm_string scm_make_string scm_string_ref
5988 scm_string_set_x scm_string_equal_p scm_string_append):
5989 Bugfix according to scm patch from Aubrey Jaffer:
5990 Corrected long-standing
5991 (not (eqv? (integer->char 128)
5992 (string-ref (make-string 1 (integer->char 128)) 0)))
5993 bug found by John Kozak <jk@noontide.demon.co.uk>.
5995 * strports.c, strports.h: Make scm_eval_0str return the value of
5996 the last expression evaluated (previously, it returned void).
5998 * strports.c, strports.h: New function: scm_read_0str. Does what
6001 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6003 * simpos.c (scm_getenv): return #f if string can't be found in the
6004 environment instead of throwing an exception, for compatibility
6005 with numerous other systems.
6007 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6009 * Makefile.am (.c.x): Use guile-snarf.
6010 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6012 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6014 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6016 * backtrace.c (scm_display_error_message): Made non-static, and
6017 renamed from display_error_message.
6018 * backtrace.h (scm_display_error_message): Added extern decl.
6019 * throw.c (uncaught_throw): Use it to display the error message.
6021 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6023 * inet_aton.c: Use #if 0, not #ifdef 0.
6025 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6027 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6028 to convert the returned value.
6029 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6030 the offset argument.
6032 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6034 Add new interface to catch/throw, usable from C as well as
6036 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6037 (scm_internal_catch): New function, replaces...
6038 (scm_catch_apply): Deleted.
6039 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6040 mechanism which is a bit more code, but can be used nicely from C
6041 and implement the Scheme semantics as well.
6042 (scm_internal_catch): This is the replacement; it's named after
6043 the analogous function in Emacs.
6044 (scm_catch): Reimplemented in terms of the above.
6045 (struct catch_body_data, catch_body, catch_handler): New
6046 functions, used by scm_catch.
6047 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6048 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6049 support for new cwdr.
6051 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6054 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6056 * acconfig.h: Added DYNAMIC_LINKING symbol.
6057 * configure.in: Add option and checks for dynamic linking.
6058 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6059 dynl.h: New files for dynamic linking support.
6060 * Makefile.am (libguile_a_SOURCES):
6062 (modinclude_HEADERS): Added "dynl.h".
6063 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6065 * init.c (scm_boot_guile_1): Call
6066 scm_init_dynamic_linking to initialize dynamic linking support.
6068 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6070 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6071 (as we Schemers say). It needs to be global, so that I can tweak
6072 it for the proper operation of unexec.
6073 (scm_boot_guile_1_live): New variable, see above.
6075 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6077 * guile-snarf.sh: Removed.
6078 * PLUGIN/guile.libs: Added dependency for -lm.
6079 * acinclude.m4: Renamed from aclocal.m4.
6080 * PLUGIN/greet: Removed.
6081 * Makefile.am, aclocal.m4: New files.
6082 * configure.in: Updated for Automake.
6084 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6086 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6087 and not top_level_lookup_thunk_var.
6089 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6091 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6093 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6095 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6096 Scheme function, instead of syntax. Single argument is now a
6099 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6101 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6102 scm_ra_divide): Properly terminate statements passed as arguments
6103 to IVDEP macros. (Thanks to Bernard Urban.)
6105 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6106 with non-constant sizes. (Thanks to Bernard Urban.)
6108 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6110 It's an "eval closure", not an "eval thunk." A thunk is a
6111 function of no arguments.
6112 * root.h (struct scm_root_state): Renamed
6113 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6114 (scm_top_level_lookup_closure_var): Renamed from
6115 scm_top_level_lookup_thunk_var.
6116 * root.c (mark_root): Uses changed.
6117 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6118 * init.c (scm_start_stack): Uses changed.
6119 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6120 Change scheme-visible name to *top-level-lookup-closure* from
6121 *top-level-lookup-thunk*.
6123 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6125 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6126 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6128 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6130 * gc.c (struct scm_heap_seg_data): Doc fixes.
6132 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6133 sweeping. Then, prepend each segment's free cells to its
6134 freelist, rather than wiping out the old value. (Thanks to Marius
6137 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6138 scm_check_freelist, scm_debug_newcell): New functions and
6139 variables, for debugging freelist problems.
6140 * pairs.h (SCM_NEWCELL): New debugging version added.
6141 * gc.h (scm_debug_newcell): Added extern declaration, used by
6142 debugging version of SCM_NEWCELL.
6144 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6146 On some systems <libc.h> conflicts with <unistd.h>, and should not
6147 be #included at all.
6148 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6149 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6150 * configure.in: Call it.
6151 * posix.c, filesys.c: Use its results to decide whether or not to
6153 * configure, scmconfig.h.in: Rebuilt with autoconf and
6156 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6158 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6159 pointer to the stdio stream before calling scm_setbuf0, so the
6160 latter will be able to retrieve it. I'm surprised this didn't
6161 segfault earlier. (Thanks to Christopher Lee.)
6163 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6165 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6168 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6170 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6171 number of stack narrowing specifier pairs. The first specifier in
6172 a pair controls inner border, the second the outer border. A
6173 number means cut that number of frames, a procedure object means
6174 cut until that object is found in operator position in a frame.
6176 * root.c (cwdr): Bugfix.
6178 * read.c: Recording of positions disabled by default.
6180 * procs.c (scm_closure_p): New function.
6182 * posix.c (scm_tmpnam): New function.
6184 * load.c: Added #include "throw.h".
6185 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6188 * load.c, load.h (scm_read_and_eval_x): New function.
6190 * eval.c: Renamed debug option "deval" to "debug".
6192 (scm_eval_x): `eval!' is no longer accessible from the scheme
6193 level. Motivation: We can't allow operations which introduce
6194 glocs into the scheme level. Guile's type system can't handle
6195 these as data. Use `eval' or `read-and-eval!' as replacement.
6197 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6198 SCM_CONSP since this is a macro!; Set vframe.prev to
6199 scm_last_debug_frame instead of 0. In this way we can look
6200 "above" the virtual start stack frame if we wish.
6201 (scm_debug_hang): New function: Useful for debugging Guile in
6202 certain tricky situations. Will probably be removed later...
6204 * debug.h: Changed semantics of debug option "backtrace". This
6205 option now only indicates whether we want automatic backtrace at
6208 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6210 * ports.c: #include "filesys.h"
6211 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6213 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6214 Motivation: This is system specific code which is related to file
6215 I/O. It also may use select. Added code by Gary Houston to
6216 detect presence of character in stdio buffers.
6218 * libguile.h: #include "libguile/libpath.h"
6220 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6221 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6222 SCM_SITE_DIR; Install libpath.h among the other include files.
6224 * load.c, load.h (scm_sys_package_data_dir): New function.
6226 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6228 * stacks.h: Bugfix: Don't use tail-array length field as stack
6229 length field! This screwed GC.
6231 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6233 * _scm.h: Added #ifndef around definition of macros min and max.
6235 * __scm.h: Added hooks for threads to plugin to in ints protection
6236 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6237 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6238 the main code in these macros duplicated and spread over multiple
6239 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6240 SCM_THREAD_SWITCHING_CODE.
6242 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6244 * snarf.h: New file.
6245 * guile-snarf.sh: New file.
6246 * Makefile.in (inner_h_files): Added snarf.h
6247 (ancillary, install, uninstall, distclean): Added actions for
6249 (.c.x): Use guile-snarf.
6250 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6251 (gen_c_files): Note that these depend on guile-snarf.
6252 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6253 now in "snarf.h". Added #include "snarf.h" to get them.
6254 * libguile.h: Added #include "snarf.h".
6255 (Patches applied and tweaked by Jim Blandy.)
6257 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6259 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6260 standards suggest against providing prototypes for system
6261 functions. Thanks to Greg Troxel.
6263 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6265 * strports.c (scm_eval_0str): New function.
6266 #include "read.h", to get prototype for scm_read.
6267 * Makefile.in (strports.o): Update dependencies.
6268 * strports.h: New prototype.
6270 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6271 scheme name from "int?" to "integer?". It seems to do the job.
6272 * numbers.h: Rename prototype too.
6273 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6276 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6277 scm_num_eq_p): Rename these according to R4RS conventions: call
6278 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6279 to making libguile R4RS compliant without ice-9...
6281 * load.c (scm_sys_search_load_path): Search for files under all
6282 extensions listed in the %load-extensions variable. If FILENAME
6283 is absolute, return it unchanged, without searching the load path.
6284 (scm_loc_load_extensions): New variable, pointing to
6285 %load-extensions' value cell.
6286 (scm_init_load): Initialize it, and the value it points to.
6287 (scm_primitive_load_path): Improve error reporting.
6289 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6290 of new Scheme variable %load-hook.
6291 (scm_primitive_load): Apply %load-hook to filename.
6293 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6295 * configure.in: add tests for figuring out whether buffered data
6296 is available in a FILE structure, which is needed by char-ready.
6298 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6301 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6302 exceptions using misc_error instead of syserror. It seems a bit
6303 odd to throw an exception if a string can't be found in the
6304 environment, but it's consistent with open-file, stat etc.
6305 (simpos.h): remove sys_ from getenv.
6307 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6308 occurs, throw an error instead of returning errno. Return value
6310 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6312 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6314 * filesys.c (scm_stat2scm): derive file type and permissions from
6315 the stat mode and append them to the returned vector.
6316 There isn't much overhead in doing this and it avoids the need to
6317 work with S_IRUSR et al. in Scheme.
6318 Define symbols scm_sym_regular etc.
6319 (scm_init_filesys): don't intern S_IRUSR etc.
6321 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6322 and s_primitive_load_path.
6324 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6326 * error.h: don't declare error symbols. prototype for scm_misc_error.
6328 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6331 * error.c: use SCM_SYMBOL to set up error keys.
6332 scm_misc_error: new procedure.
6334 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6336 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6337 between `#!' and `!#' is ignored.
6338 (skip_scsh_block_comment): New function.
6340 * feature.c (scm_set_program_arguments): New argument, FIRST.
6341 * feature.h: Update prototype.
6342 * init.c (scm_boot_guile_1): Pass new argument to
6343 scm_set_program_arguments.
6345 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6347 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6348 (scm_boot_guile): Call scm_set_program_arguments here, later than
6349 the old initialization.
6351 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6352 initialization procedure.
6353 - Delete in, out, err arguments; there are other perfectly good
6354 ways to override these when desired.
6355 - Delete result argument; this function shouldn't ever return.
6356 - Rename init_func argument to main_func, for less confusion.
6357 - Delete boot_cmd argument; main_func is more general.
6358 -Add 'closure' argument, to help people pass data to main_func
6359 without resorting to global variables.
6360 - Abort if reentered; don't bother returning an error code.
6361 - Call scm_init_standard_ports to set up the default/current
6362 standard ports; no need to pass them to scm_start_stack.
6363 - Remove code to evaluate the boot_cmd, and start the repl; let
6364 the user do something like that in main_func if they want.
6365 - Remove code to package up a return value; main_func can do any
6367 - Call exit (0), instead of returning.
6368 (scm_start_stack): Don't initialize the I/O ports here; that's
6369 weird. Delete in, out, err arguments. Move guts to
6370 scm_init_standard_ports, scm_stdio_to_port.
6371 (scm_init_standard_ports): New function, to set up current and
6372 default standard ports.
6373 (scm_start_stack, scm_restart_stack): Make these static.
6374 * init.h (scm_boot_guile): Adjust declaration.
6375 (scm_start_stack, scm_restart_stack): Remove externally
6376 visible declarations for these.
6377 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6379 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6380 written out several times in scm_start_stack.
6381 * fports.h: New declaration for the above.
6383 * feature.c (scm_set_program_arguments): New function.
6384 * feature.h: New declaration for the above.
6386 * ports.c: Formatting tweak.
6388 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6390 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6391 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6392 for obtaining the address of a car or cdr field. Motivation:
6393 &SCM_CXR make assumptions about the internal structure of the
6396 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6397 Motivation: see SCM_CXRLOC.
6399 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6400 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6401 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6402 Motivation: Safer use. Some other macros are defined in terms of
6403 these operations. If these are defined using the SCM_SETCXR
6404 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6405 to inefficiency and an <e1> with side-effects could potentially
6406 break. Also, these particular operations are heavily utilized in
6407 the garbage collector. In unoptimized code there will be a
6410 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6411 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6412 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,

6415 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6416 vports.c: Cleaned up use of pairs: Don't make any special
6417 assumptions about the internal structure of selectors and
6418 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6419 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6420 (Among other things, this change makes it easier to build Guile
6421 with certain compilers which have problems with casted lvalues.)
6423 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6425 * stacks.c: Improve selection of relevant stack frames when making
6426 a stack object. Introduce one level of indirection in the stack
6427 object to make it possible to "narrow" to a certain region of the
6428 stack. This facilitates making use of more clever algorithms (not
6429 implemented) for selecting relevant frames and gives a cleaner
6430 design since selection of frames can be done independently of
6431 extraction of frames from the real stack.
6432 (scm_stack_id): Also take #t as argument which means look at
6435 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6436 Turn n_tail into an integer directly representing current number
6437 of frames in stack. Add field tail.
6439 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6441 * debug.c (scm_make_memoized): Made it available at scheme level.
6442 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6443 SCM_NIMP before applying heavier predicates in argument checking.
6444 (scm_local_eval): Also take memoized object as argument.
6446 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6447 aren't created with zero length, but should such a strange
6448 creature suddenly turn up...
6450 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6452 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6453 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6455 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6457 * variable.c (scm_make_variable): Make the name hint optional, as
6459 (anonymous_variable_sym): Renamed from variable_sym. All uses
6462 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6463 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6464 of scm_primitive_load_path was also changed to
6465 "primitive-load-path", from "%try-load-path". Callers changed.
6466 We'd like to respect the convention that a function named
6467 "try-mumble" should behave just like the function called "mumble",
6468 but return #f instead of signalling some error.
6469 * load.h: Rename prototypes.
6471 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6473 * print.c (make_print_state, grow_print_state), print.h: Modified
6474 the print state representation: Don't use a tail array for
6475 recording of circular references. Resizing of the print state
6476 structure invalidates the print state pointer. To avoid passing
6477 around an indirect print state reference to all printing
6478 functions, we instead let the print state reference a resizable
6481 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6483 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6484 Don't crash when passed an improper list terminated by a
6485 non-immediate value.
6487 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6489 Allocate data for structures on an eight-byte boundary, as
6490 required by the tagging system.
6491 * struct.c (alloc_struct): New function.
6492 (scm_make_struct, scm_make_vtable_vtable): Call it.
6493 * struct.h (scm_struct_n_extra_words): Bump to 3.
6494 (scm_struct_i_ptr): New "field".
6495 * gc.c (scm_gc_sweep): When we need to free the data, use the
6496 information stored by alloc_struct to find the beginning of the
6497 block allocated to the structure, so we can free it.
6499 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6501 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6504 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6505 (scm_debug_info): New member: id.
6507 * stacks.c: Stacks are now represented as structs; Stacks have an
6508 id given to them by `start-stack'.
6509 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6511 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6512 Changed stack representation.
6514 * debug.c (scm_procedure_name): Try procedure property `name' for
6515 compiled closures aswell.
6517 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6519 * eval.c: scm_i_name moved to gsubr.c
6520 (scm_m_define): Record names of all kinds of procedure
6521 objects. (Earlier, only closures were recorded.)
6523 * procprop.h: Added declaration of scm_i_name.
6525 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6526 (scm_make_gsubr): Record names of compiled closures.
6528 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6530 * debug.c, debug.h: Removed obsolete code.
6532 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6533 stacks.c: Renamed regs --> scm_contregs.
6535 * print.c (scm_free_print_state): Cleanup print state before
6536 returning it to pool. It is better to do it here than in
6537 scm_prin1 since scm_prin1 is called often.
6539 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6540 s_set_source_property_x): Check that first argument is a pair or a
6543 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6544 scm_i_line, scm_i_column and scm_i_breakpoint global.
6546 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6547 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6550 * debug.h: Added debug object smob declaration and macro
6553 * configure.in: Build with backtrace.o and stacks.o if debug
6556 * Makefile.in: Added entries for new files: backtrace.c,
6557 backtrace.h, stacks.c and stacks.h.
6559 * symbols.c (scm_sym2ovcell): Fixed documentation.
6561 * _scm.h (min, max): Added.
6563 * async.c: Moved `min' macro to _scm.h.
6565 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6566 SCM_BACKTRACE_INDENT.
6568 * eval.c: Added new debug options `maxdepth' and `indent'.
6570 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6572 * print.h: Added selector SCM_PRINT_STATE.
6574 * print.c: New functions: scm_make_print_state,
6575 scm_free_print_state.
6577 * print.h: Added declarations for scm_make_print_state,
6578 scm_free_print_state.
6580 * debug.c (scm_m_start_stack): New acro.
6582 * debug.h: Small cleanup.
6584 * init.c (scm_boot_guile_1): Moved scm_init_debug below

6612 More prototype-related changes from Marius Vollmer:
6613 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6614 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6615 * ports.h (ptobfuns): Added prototypes. This means some casting in
6617 * fports.c: Added casts for initializations, since the functions
6618 are defined to take FILE * as their stream argument, not SCM.
6619 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6620 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6621 to `char *str_data' to conform to prototype.
6623 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6625 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6627 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6629 * stime.c, stime.h: use SCM_P method.
6631 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6633 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6634 be given at least two arguments. Insist that lst's last element
6635 be a list, but don't make any requirements of its predecessors.
6637 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6639 * eval.c (scm_nconc2last): Revert last change; there seems to be
6640 other stuff going on here.
6642 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6644 * eval.c (scm_nconc2last): Make sure that each element of lst
6645 (which is a list of argument lists, except for the tail) is a
6646 proper list, i.e., finite and terminated by '().
6648 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6650 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6653 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6654 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6657 * vectors.c (scm_make_vector): Fill vectors with the undefined
6658 value, to help make Guile Scheme code more portable to other
6661 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6662 * symbols.h, tags.h: Doc fixes.
6664 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6666 * async.c (scm_take_signal): Doc fixes.
6668 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6670 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6671 want to subtract it from the modulus; we just want to leave it
6674 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6676 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6679 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6681 * throw.c (scm_catch_apply): Finished implementation of
6684 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6686 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6688 (scm_init_filesys): set "i/o-extensions" feature.
6691 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6693 * Makefile.in (root.o): Correct dependencies.
6695 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6697 * Makefile.in: Added dependency entry for root.o.
6699 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6700 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6702 * init.c (scm_start_stack): Set initial root continuation number
6705 * procs.c: New function: scm_thunk_p.
6707 * procs.h: Added declarations of scm_thunk_p.
6709 * root.c: Renamed `call-with-new-root' -->
6710 `call-with-dynamic-root'.
6711 (cwdr): Removed allocation of new root state. This should be done
6712 separately by use of scm_make_root.
6713 (scm_apply_with_dynamic_root): New function: Does what it
6714 sounds like. Needed when spawning threads.
6716 * root.h: Added member last_debug_frame to root state.
6717 Added #include "libguile/debug.h"
6719 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6720 arguments. The motivation is that code in root.c needs catch
6721 functionality, and we want to avoid code duplication.
6722 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6723 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6724 handlers that run without popping the stack into the dynwind
6727 * throw.h: Added prototypes for scm_catch_apply and
6730 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6732 * root.h (scm_root, scm_set_root): Decouple thread support details
6733 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6734 SCM_SET_THREAD_LOCAL_DATA.
6736 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6737 and tortoise scanning loop.
6739 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6741 * Makefile.in: Rebuild dependencies.
6743 * libguile.h: #include "libguile/print.h" before "smob.h", since
6744 the latter uses the print_state structure.
6746 * throw.c (scm_ithrow): Use the correct variable when checking to
6747 see if a given element of scm_dynwinds is a valid catch.
6749 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6750 structure, abort; don't just silently ignore the garbage.
6752 * _scm.h: #include "print.h" here, since it seems to be used just
6754 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6755 strports.c, unif.h: Don't #include "print.h".
6757 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6759 * feature.h (scm_loc_features): Removed external declaration.
6760 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6762 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6764 * feature.c (scm_init_feature): Added threads feature (needs to be
6765 initialized here, since features doesn't exist when
6766 scm_init_threads is called).
6768 * libguile.h: Added #include "libguile/../threads/threads.h".
6769 (This is a kludge to get thread support working. This should be
6772 * configure.in, acconfig.h: Added flags for thread support.
6774 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6777 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6778 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6781 * _scm.h: Added conditional #include "threads.h"
6783 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6784 SCM_THREADS_SWITCHING_CODE.
6786 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6787 allocate the basic dynamic root object.
6788 (scm_boot_guile): Added call to scm_init_root.
6790 * root.c, root.h: Added root smob.
6791 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6792 functions: Implements dynamic roots mostly according to spec in
6793 SCM manual. Main difference is that the second argument is a
6794 throw handler rather than an error "thunk".
6796 * root.h: Added declaration of scm_init_root.
6798 * root.c: Added #include "genio.h", #include "smob.h", #include
6799 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6801 (scm_init_root): Added #include "root.x".
6803 * throw.c: Added #include "stackchk.h"
6804 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6805 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6806 can be used in scm_call_with_new_root; Added reenabling of stack
6807 checking when catching a throw.
6809 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6811 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6813 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6814 element is not found, as per R4RS.
6816 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6818 * list.c: Doc fixes throughout.
6820 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6822 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6823 declare the char * to be const. Avoids a warning in rgx.c.
6825 * ports.h: spelling fix.
6827 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6830 * load.c (scm_sys_try_load_path): throw an error if file not found
6831 (like it says it in NEWS).
6833 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6835 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6836 PROPS slot to '(), not #f; it's an empty alist.
6838 * throw.h, throw.c: Use SCM_P instead of #if hair.
6840 Remove special support for uncaught throws; see throw.c for
6842 * throw.c (uncaught_throw): New function.
6843 (scm_ithrow): Call uncaught_throw if we don't find a throw
6844 target; don't mess with scm_bad_throw_vcell.
6845 (scm_bad_throw_vcell): Variable deleted.
6846 (scm_init_throw): Don't initialize it.
6848 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6851 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6853 * numbers.c (scm_istr2int): If the number is short (as most
6854 numbers are), just call scm_small_istr2int to deal with it.
6855 (scm_small_istr2int): New function, created by un-#ifdefing the
6856 non-bignum version of scm_istr2int and renaming it.
6858 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6860 * load.c (scm_sys_try_load): don't check whether value returned
6861 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6862 Change the Scheme name from %try-load to primitive-load.
6864 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6865 Can avoid passing a message, allowing it to be derived in the
6866 error handler (e.g., if we want to throw to the key both from
6869 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6871 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6872 references now have a new appearance which is more compact and
6873 also gives a clue about what the target of the reference is.
6874 By setting parameters in the print state, more fancy printing can
6875 be achieved. This is used by the (not yet commited) backtrace
6878 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6880 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6883 * print.c: Added #include "struct.h". Removed function
6886 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6887 scm_iprin1. Removed prototype for scm_prlist.
6889 * arbiters.c (prinarb),
6890 async.c (print_async),
6891 debug.c (prindebugobj, prinmemoized),
6892 eval.c (prinprom, prinmacro),
6893 filesys.c (scm_fd_print, scm_dir_print),
6895 mallocs.c (prinmalloc),
6896 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6897 smob.h (scm_smobfuns),
6898 srcprop.c (prinsrcprops),
6900 unif.c, unif.h (scm_raprin1, rapr1),
6901 variable.c (prin_var): Changed argument `int writing' to
6902 `scm_print_state *pstate'.
6904 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6905 that it will be called before scm_init_print.
6907 * print.c (scm_prin1): Print states are now allocated when calling
6908 scm_prin1 and then passed around to all printing functions as an
6909 argument. A cache `print_state_pool' enables reuse of print
6911 (scm_make_print_state): New function.
6912 (scm_iprin1): Adaption to print states.
6913 (scm_iprlist): An initial "hare and tortoise" scan brings down
6914 time complexity to O (depth * N). (Better time complexity will be
6915 achieved when the printing code is completely rewritten.)
6917 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6919 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6920 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6921 it gets done whether or not the cache variable has a value.
6923 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6925 Distinguish #f and ().
6926 * __scm.h: #undef SICP.
6927 * pairs.h (SCM_EOL): Delete this definition, equating it with
6929 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6930 the value it used to have. Doc fixes, too.
6932 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6934 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6935 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6936 Lord's implementation of structs, allowing for tail arrays as
6937 described in the manual. Also fixed some bugs. (Both the interface
6938 and the implementation should be improved.)
6940 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6942 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6943 People who whish to see the source can do `(print-enable 'source)'.
6944 Removed #ifdef DEBUG_EXTENSIONS.
6946 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6948 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6949 integer (assuming for now accepting an integer is a good thing).
6951 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6952 %S will be used instead for write'ing arguments.
6954 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6955 asserts. fix a few other asserts.
6956 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6957 scm_uniform_vector_ref, scm_array_set_x,
6958 scm_dimensions_to_unform_array): change args in
6959 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6960 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6961 scm_substring_fill_x): likewise.
6962 gsubr.c (scm_gsubr_apply): likewise.
6963 eval.c (SCM_APPLY): likewise.
6965 * eval.c (4 places): replace scm_everr with lgh_error or
6968 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6969 scm_memory_error): new procedures.
6970 scm_everr: deleted. can use scm_wta, dropping first two args.
6971 scm_error: convert NULL subr to SCM_BOOL_F.
6973 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6976 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6979 * error.c, error.h: new error keys: scm_arg_type_key,
6980 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6982 scm_wta: reimplement using lgh_error instead of scm_everr.
6984 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6986 * gdbint.c: scm_lread now has one more argument.
6988 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6989 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6990 loading source from non-file ports, which, e. g., happens when
6991 using the Emacs interface).
6993 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6996 * read.c: Added code for recording of positions of source code
6997 expressions; New functions: recsexpr, scm_lreadrecparen;
6998 _scm_make_srcprops --> scm_make_srcprops
6999 (scm_flush_ws): Removed updating of positions counters. This work
7000 is already done by scm_gen_getc
7002 * read.h: Added prototype for scm_lreadrecparen
7004 * print.c: Added #include "alist.h"
7006 * eval.c: Added #include "hash.h"
7008 * eq.c: Added #include "ramap.h"
7010 * options.c: Documentation fixes.
7012 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7013 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7014 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7015 --> scm_make_srcprops
7017 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7018 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7019 function calls in the definition of the whash access macros.
7021 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7023 * init.c (scm_boot_guile): Add level of indirection to
7024 scm_boot_guile_1() to ensure that stack base pointer is properly
7025 initialized. There was no guarantee that variable i was the
7026 highest/lowest variable on stack (i.e. the call frame of
7027 scm_boot_guile was not completely protected from gc).
7029 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7031 * ports.h (scm_port_table): put back file_name, it will be used to
7032 support debugging. Undo related changes in fports.c, ioext.c,
7035 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7037 * ports.h (scm_port_table): remove file_name member for now, it seems
7039 * fports.c (scm_open_file): don't set file_name in PTAB.
7040 (prinfport): don't use file_name in PTAB.
7041 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7042 * ports.c (scm_add_to_port_table): don't intialize file_name.
7043 (scm_port_file_name): remove for now.
7044 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7046 * fports.h (scm_mkfile): prototype deleted.
7047 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7049 * debug.c, unif.c: use scm_out_of_range instead of
7050 wta for range errors (ASSERT still needs work).
7052 * error.c, error.h (scm_out_of_range): new procedure.
7054 * error.c, error.h (scm_out_of_range_key): new key.
7056 * posix.c (scm_sync): #else was missing.
7058 * error.c, error.h: append _key to names scm_num_overflow and
7061 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7062 of consing an empty list.
7063 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7064 of macros, saves code and string space.
7065 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7066 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7067 lower case. Rename scm_syserror_m to scm_syserror_msg.
7068 error.h: prototypes for new procedures.
7070 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7072 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7074 * error.c, error.h: setup scm_num_overflow key.
7076 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7077 Remove definition of SCM_OVSCM_FLOW.
7079 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7081 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7082 explicit message and args.
7084 * error.c, error.h, __scm.h: change system_error_sym to
7087 * error.c (system_error_sym): remove leading %% from the Scheme name
7090 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7092 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7094 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7095 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7096 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7097 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7098 renamed. (These were introduced by unsupervised name
7101 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7103 * print.c: Added code for detection of circular references during
7104 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7105 a hook for printing of closures (accessible via print options).
7106 This leads to a split of calls to scm_iprin1 into two classes:
7107 elementary print operations (e. g. the code which prints a smob)
7108 still use scm_iprin1 while top level calls (like scm_display) use
7109 scm_prin1. scm_prin1 begins by clearing the data structure used
7110 to record reference information.
7112 * print.h: Added declarations of scm_prin1 and scm_prlist.
7114 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7116 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7118 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7120 * error.c (err_head): scm_iprin1 --> scm_prin1
7122 * debug.c: Adjusted header comment.
7126 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7128 * strerror.c: Doc fix.
7130 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7132 * gdbint.c (gdb_read): Now possible to run during GC.
7133 (unmark_port, remark_port): New functions.
7135 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7137 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7138 of allocating a new string object. Also, increase size by
7139 the factor 2 instead of 1.5.
7141 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7143 * __scm.h (SCM_P): Corrected to run under traditional C.
7145 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7148 * async.c: Calls to scm_sysintern corrected.
7150 * async.h (scm_async_clock): Redundant declaration removed.
7152 * continuations.c (scm_dynthrow): Redundant declaration removed.
7154 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7155 Definition typos corrected.
7157 * debug.h: Missing declarations of functions in debug.c added
7160 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7161 Missing declarations to functions in eval.c added.
7163 * filesys.c: Possibly uninitialized variable rv.
7165 * gc.h (scm_object_addr, scm_unhash_name): Missing
7166 declarations of functions defined in gc.c added.
7168 * genio.c: Possible typos str_data -> wstr_data. ???
7170 * genio.c: Possibly unintended shadowing of local variable
7171 `int c' (gotos out of scope of inner `c'). ???
7173 * init.c: Uninitialized `SCM last' may be used.
7175 * ioext.h: (scm_sys_isatty_p): Typo.
7177 * list.h (scm_list_head): Missing prototype for function in
7180 * numbers.c (scm_two_doubles): Changed from extern to static
7181 (is used only within numbers.c).
7183 * numbers.h: Repeated declarations removed.
7185 * ports.h (scm_close_all_ports_except): Declaration for the
7186 function defined in ports.c added.
7188 * posix.h: Missing declarations added.
7190 * procs.h (scm_make_subr_opt): Missing declaration added.
7192 * socket.h (scm_sys_gethost): Missing declaration added.
7194 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7196 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7197 Missing declarations added.
7199 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7201 * struct.c: Uninitialized variable `SCM answer' may be used.
7203 * unif.c (l2ra): Declaration prototype.
7205 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7206 defined in ramap.c).
7208 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7209 Redundant declarations removed (they are in ramap.h).
7211 * variable.h (scm_make_udvariable,
7212 scm_make_undefined_variable): Declaration corrected to
7213 correspond variable.c.
7215 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7216 Missing declarations added.
7218 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7220 * Makefile.in (distclean): Don't forget to delete fd.h.
7222 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7224 * fd.h.in, tags.h: Trivial cleanups.
7226 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7227 marksweep.h just declared functions from gc.c.
7228 * gc.h, libguile.h: Don't #include "marksweep.h".
7229 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7230 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7231 dependencies updated.
7233 * libguile.h: Don't #include "files.h"; it's been deleted.
7235 * files.c (scm_sys_delete_file): Moved to filesys.c.
7236 File is now empty; deleted.
7238 * filesys.c: scm_sys_delete_file is now here. Remove
7239 #if's; they seem to rely on remnants of an old portability
7240 regimen. If the problems come up again, solve them properly,
7241 using autoconf. Specifically: Don't test M_SYSV, and #define
7242 remove to be unlink if it's #defined; don't use remove just
7243 because HAVE_STDC_HEADERS is #defined.
7244 * filesys.h: Add declarations for scm_sys_delete_file.
7245 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7246 files.o, files.h, files.c, and files.x.
7247 * init.c: Don't #include "files.h", and don't call scm_init_files.
7249 Use SCM_P instead of PROTO; the latter intrudes on the user's
7251 * params.h: Deleted; definition of SCM_P moved to...
7252 * __scm.h: ... here, where it replaces PROTO macro.
7253 * libguile.h, smob.h: Don't #include "params.h".
7254 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7255 smob.h: Fix prototypes accordingly.
7256 * Makefile.in: Update dependencies.
7257 (inner_h_files): Remove params.h.
7259 * gc.c: #include "gc.h"; every module should include its header,
7260 to let the compiler cross-check the declarations against the
7263 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7264 simpos.h: #include "libguile/__scm.h".
7266 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7268 * init.c: Don't forget to #include smob.h and init.h.
7269 * Makefile.in: Dependencies updated.
7271 * smob.h: Use PROTO instead of #if __STDC__.
7273 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7275 * __scm.h: Doc fixes.
7277 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7278 <angles>; this allows `make depends' to work properly.
7280 * libguile.h: #include smob.h and pairs.h before the others; they
7281 define typedefs used by other headers.
7283 C files should #include only the header files they need, not
7284 libguile.h (which #includes all the header files); the pointless
7285 recompilation was wasting my time.
7286 * Makefile.in (all .o dependency lists): Regenerated.
7287 * libguile.h: Don't try to get a definition for size_t here...
7288 * __scm.h: Do it here.
7289 * _scm.h: Since this is the internal libguile header, put things
7290 here that all (or a majority) of the libguile files will want.
7291 Don't #include <libguile.h> here; that generates dependencies on
7292 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7293 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7294 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
7296 * alist.c: Get "eq.h", "list.h", "alist.h".

7305 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
7306 "genio.h", "throw.h", "eval.h".
7307 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".
7308 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
7310 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
7311 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",
7312 "hashtab.h", "procprop.h", "markers.h", "smob.h", "throw.h",
7313 "continuations.h", "eq.h", "sequences.h", "alist.h", "append.h",
7315 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
7316 * feature.c: Get "feature.h".
7317 * files.c: Get "files.h".
7318 * filesys.c: Get "filesys.h", "smob.h", "genio.h".
7319 * fports.c: Get "fports.h", "markers.h".
7320 * gc.c: Get "async.h", "unif.h", "smob.h", "weaks.h",
7321 "genio.h", "struct.h", "stackchk.h", "stime.h".
7322 * gdbint.c: Get "gdbint.h", "chars.h", "eval.h", "print.h",

7391 * weaks.c: Get "weaks.h".
7393 * stackchk.h: #include "libguile/debug.h",
7395 * print.h, read.h: #include "options.h", since everyone who uses
7396 either of these files will need that.
7398 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7399 anyone who uses this file will need them to define the smob
7400 printing functions. Also, get markers.h, since people will need
7401 to #define the mark functions.
7403 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7404 * ports.h: ... to here.
7406 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7407 don't rely on archaic C default type rules.
7409 * fports.h: #include "libguile/ports.h", since you need that in
7410 order to parse this.
7412 * genio.h: #include "libguile/print.h", because you need that to
7413 parse this; don't bother #including "ports.h", since print.h gets
7416 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7418 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7419 this; it's now a reference to an element of *scm_root.
7421 * debug.h: Don't #include "options.h"; the compiler won't be able
7422 to find that once the headers are installed; instead, #include
7423 "libguile/options.h".
7424 * gc.h: Same, with marksweep.h.
7425 * mbstrings.h: Same, with symbols.h.
7426 * scmhob.h: Same, with _scm.h.
7427 * smob.h: Same, with params.h.
7429 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7430 C files; there's no need for this, and it forces recompilations
7433 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7435 * error.c (scm_error): declare scm_error_callback.
7437 * error.h: prototype for scm_error_callback.
7439 * __scm.h: define lgh_error.
7440 (SCM_SYSERROR): redefine using lgh_error.
7442 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7444 * error.c (scm_error): new procedure.
7446 * error.h: prototype for scm_error.
7448 * Makefile.in (install): install scmconfig.h from the current
7449 directory, not $(srcdir).
7451 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7453 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7454 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7455 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7456 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

7460 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7461 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7462 vports.h, weaks.h: #include "libguile/__scm.h", not
7463 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7464 dependencies are within libguile properly.
7466 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7468 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7469 when scmconfig.h doesn't exist.
7471 * load.c (scm_sys_try_load): Correct spelling.
7473 * feature.c (scm_loc_features): Make this static.
7475 * Makefile.in (libpath.h): Omit trailing slash from path. We
7476 shouldn't require it of users, so why put it here?
7478 Move code to initialize and search %load-path from ice-9 to C
7479 code, so we can use the load-path to find the ice-9 boot code;
7480 this makes it easier to run Guile without installing it. See
7481 corresponding changes in guile/Makefile.in.
7482 * feature.c: Move stuff concerned with the load path to load.c.
7483 (scm_compiled_library_path): Deleted.
7484 Don't #include libpath.h here.
7485 * feature.h: Don't mention scm_compiled_library_path.
7486 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7487 <sys/stat.h>, and <unistd.h> (if present).
7488 (R_OK): #define if the system hasn't deigned to.
7489 (scm_loc_load_path): New variable.
7490 (scm_init_load_path, scm_sys_search_load_path,
7491 scm_sys_try_load_path): New functions.
7492 (scm_init_load): Initialize scm_loc_load_path to point to the
7493 value cell of the Scheme %load-path variable.
7494 * load.h: Add declarations for scm_sys_search_load_path,
7495 scm_sys_try_load_path.
7496 * init.c: Call scm_init_load_path.
7497 * Makefile.in (feature.o, load.o): Dependencies updated.
7499 * load.c, load.h: Rewrite using PROTO macro.
7501 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7503 * gc.c (scm_cellp): New function: C predicate to determine if an
7504 SCM value can be regarded as a pointer to a cell on the heap.
7506 * gc.h: Added declaration of scm_cellp.
7508 * gdb_interface.h: New file: The GDB interface header from the GDB
7511 * gdbint.c: New file: GDB interface.
7513 * gdbint.h: New file: GDB interface.
7515 * libguile.h: Added #include <libguile/gdbint.h>.
7517 * init.c (scm_boot_guile): Added scm_init_gdbint.
7519 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7520 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7521 found if object files and source are kept separate).
7523 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7525 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7527 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7529 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7530 TK_SRC_DIR; they're not relevant any more.
7532 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7533 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7535 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7537 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7538 search path, so we can find the <libguile/MUMBLE.h> headers.
7540 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7542 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7543 implicit in the .c.o rule.
7544 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7547 Put the library path in a header file, instead of passing it on
7548 the command line in every compilation.
7549 * Makefile.in (libpath.h): New target.
7550 (feature.o): Depend on libpath.h.
7551 (clean): Delete libpath.h.
7552 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7553 * feature.c: ... #include "libpath.h" here.
7554 * .cvsignore: Ignore libpath.h.
7556 Don't install the unwashed masses of Guile header files in the
7557 main #include path; put most of them in a subdirectory called
7558 'libguile'. This avoids naming conflicts between Guile header
7559 files and system header files (of which there were a few).
7560 * Makefile.in (pkgincludedir): Deleted.
7561 (innerincludedir): New variable; this and $(includedir) are enough.
7562 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7563 (installed_h_files): Divide this up. Now this variable lists
7564 those header files which should go into $(includedir) (i.e. appear
7565 directly in the #include path), and ...
7566 (inner_h_files): ... this new variable says which files appear in
7567 a subdirectory, and are referred to as <libguile/mumble.h>.
7568 (h_files): List them both.
7569 (install): Create innerincludedir, not pkgincludedir. Put
7570 the installed_h_files and inner_h_files in their proper places.
7571 (uninstall): Corresponding changes.
7572 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7573 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7574 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7575 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7576 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7577 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7578 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7579 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7580 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7581 vports.h, weaks.h: Find __scm.h in its new location.
7582 * __scm.h: Find scmconfig.h and tags.h in their new locations
7583 (they're both "inner" files).
7585 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7587 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7589 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7591 * posix.c: Doc fixes.
7593 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7595 * socket.c: Don't include a prototype for inet_aton; just use a
7596 K&R style declaration, to avoid warnings but minimize the chance
7597 of conflicts with the system.
7599 On NextStep, <utime.h> doesn't define struct utime, unless we
7600 #define _POSIX_SOURCE before #including it.
7601 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7602 * acconfig.h: New comment text for above CPP symbol.
7603 * configure.in: Call it.
7604 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7606 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7608 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7609 testing for __EMX__.
7611 * posix.c: #include <libc.h>, if it exists.
7613 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7614 don't even know if the latter exists.
7616 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7617 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7618 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7620 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7622 (scm_init_posix): Use them when initializing the Scheme constants
7625 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7627 * Makefile.in (libdir, includedir, bindir): Use the
7628 autoconf-supplied values, instead of deriving them ourselves.
7629 (pkgincludedir, datadir, pkgdatadir): New variables.
7630 (install, uninstall): Put the header files in a special
7631 subdirectory, not in the main search path.
7633 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7634 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7636 * Makefile.in (IMPLPATH): Deleted; never used.
7638 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7639 on the Tcl/Tk source any more.
7640 (INCLUDE_CFLAGS): Remove references to the above.
7642 * Makefile.in (version.o): Corrected dependencies.
7644 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7646 * libguile.h: #include "version.h"
7648 * init.c (scm_boot_guile): Call scm_init_version.
7649 * gscm.c (gscm_run_scm): Call scm_init_version.
7651 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7652 GUILE_VERSION): AC_DEFINE these.
7653 (acconfig.h): #undef the above symbols.
7655 * Makefile.in (libobjs): Add version.o.

7659 (version.o): New rule.
7660 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7661 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7669 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7670 weaks.o): Add version.h to dependency lists.
7671 (markers.o): Remove duplicate rule.
7673 * version.h: New file.
7675 * version.c: New file.
7677 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7679 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7680 array; use it appropriately. Since GCC is quite happy to
7681 subscript functions, it never warned us about this; we should use
7682 -Wpointer-arith in the future. I guess we never tested
7685 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7687 * socket.c: Doc and copyright fixes.
7689 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7691 * debug.c: Fixed and improved gdb support.
7693 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7695 * socket.c: Added declaration of inet_aton to avoid compiler
7696 warning. (Hope this solution is correct.)
7698 * stime.c: Added declaration of ftime. (This is missing in
7701 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7703 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7705 * Makefile.in (c_files): add strerror.c.
7707 * strerror.c: new file from Emacs' sysdep.c.
7708 maybe configure should also check for sys_errlist.
7710 * configure.in (AC_REPLACE_FUNCS): add strerror.
7712 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7714 * debug.c (scm_init_debug): Added initialization for
7715 scm_evaluator_traps.
7717 * debug.h, debug.c: Various name changes.
7718 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7719 "debug-options-interface". See commentary in options.c.
7721 * options.h, options.c: Options now have documentation strings.
7722 Also added a long explanatory commentary.
7724 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7727 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7728 last_debug_info_frame is now updated in all cases.
7730 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7733 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7735 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7736 Added option STACK_CHECKING.
7738 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7740 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7742 * __scm.h: Removed symbols for debugging support.
7744 * acconfig.h: Added symbols for debugging support.
7746 * configure.in: Added user option for debugging support.
7747 --enable-debug will include the debugging code into libguile.a.
7749 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7750 scm_relocate_chunk_to_heap.
7752 * debug.c: New file: low-level debugging support. It also
7753 includes support for debugging with gdb. (The extensions to gdb
7754 are written by Per Bothner at Cygnus.)
7756 * debug.h: New file: low-level debugging support.
7758 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7759 argument pairs. Extensive modifications to the debugging
7760 evaluator. Added "SECTION:" commentaries to clarify what happens
7761 when, during double compilation. Renamed EVALIMP --> EVALIM.
7762 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7763 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7764 the beginning of the file. New procedure: scm_unmemocopy.
7765 Added some global state variables needed by the debugging
7766 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7767 check_entry, check_apply, check_exit, debug_options and
7768 evaluator_traps. New acro: undefine.
7770 * eval.h: Renamed EVAL --> XEVAL.
7772 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7773 --> scm_make_weak_key_hash_table.
7775 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7776 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7778 * libguile.h: Conditionally include debug.h
7780 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7781 scm_object_properties shouldn't return handle. `handle' now gets
7782 initialized in scm_set_object_properties_x. scm_object_properties
7783 doesn't any longer create an entry in scm_object_whash.
7785 * options.c: New file: handling of run time options.
7787 * options.h: New file: handling of run time options.
7789 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7791 * print.c: New procedure: scm_print_options
7793 * print.h: Defines for print options.
7795 * read.c: New procedure: scm_read_options
7797 * read.h: Defines for reader options.
7799 * root.h: Added scm_source_whash among scm_sys_protects.
7801 * srcprop.c: New file: source properties.
7803 * srcprop.h: New file: source properties.
7805 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7806 (Bug found by A. Green.)
7808 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7810 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7812 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7814 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7816 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7817 and should be called by the final client.
7819 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7821 * gc.h: Use the PROTO macro when declaring functions.
7822 * gc.c: Use the PROTO macro when declaring static functions.
7823 Remove the CPP hair around function definitions.
7825 * gc.c (scm_init_storage): Initialize scm_asyncs.
7827 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7828 preprocessor symbol; "__scm.h" is where it might get #defined.
7829 * __scm.h: Similar: #include <scmconfig.h> before testing
7832 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7834 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7836 * init.c (scm_boot_guile): Add init_func argument; call
7837 (*init_func) instead of calling scm_appinit; it's ucky to
7838 hard-code names for the user's procedures.
7839 * init.h (scm_boot_guile): Adjust declaration.
7841 * __scm.h (PROTO): New macro, for declaring functions with
7844 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7845 eliminate all the __STDC__ conditionals.
7846 (scm_boot_guile): Add declaration.
7847 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7848 Remove __STDC__ conditionals around function definitions; the
7849 declarations in init.h will provide the same information, more
7852 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7853 complain about it in the error message; the error message is
7854 adequate without that note, and there's nothing the user can do
7857 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7859 * Makefile.in (ancillary): Drop def.sed.
7861 * posix.c (scm_init_posix): Use numeric values, rather than
7862 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7863 F_OK. The symbols aren't available on some systems, and I'm
7864 pretty sure their values are fixed by common widespread practice.
7865 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7867 More functions unavailable on some systems.
7868 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7869 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7871 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7872 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7873 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7874 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7875 stub that signals an error as the #else.
7877 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7879 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
7881 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
7883 * unif.c: include ramap.h.
7885 * read.c (endif): case_insensative_p renamed case_insensitive_p.

7889 * ports.c: include sys/ioctl.h.
7891 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
7893 * configure.in: check for sys/ioctl.h.
7895 * ports.c: include <malloc.h> not "malloc.h".
7897 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7899 * fports.c: remove ttyname and tmpnam declarations.
7901 * posix.c: fewer ttyname declarations.
7903 * fports.c: include <string.h> not "string.h".
7905 * init.c, ioext.c: include string.h and unistd.h.
7907 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7909 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
7910 genio.c, simpos.c, vports.c: include string.h.
7912 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
7914 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
7916 (scm_addr_buffer_size): change type from scm_sizet to int.
7917 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
7918 from scm_sizet to int.
7920 * error.c: include unistd.h.
7922 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
7925 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
7927 * __scm.hd, def.sed: deleted.
7929 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
7931 Changes for NeXT, suggested by Robert Brown.
7932 * configure.in: Call AC_TYPE_MODE_T.
7933 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
7934 NeXT. Put header file list in alphabetical order.
7935 * configure, scmconfig.h.in: Regenerated.
7936 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
7938 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
7941 * acconfig.h: New file, providing documentation for the CPP
7942 symbols defined in configure.in
7943 * acconfig-1.5.h: Removed; superceded by the above.
7945 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
7947 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
7949 * fports.c (scm_open_file): don't return #f, throw error.
7951 * ioext.c (fileno): renamed from %fileno.
7952 (soft-fileno): deleted.
7954 * ports.c (scm_port_revealed): don't need to check for -1 from
7956 (scm_set_port_revealed_x): return unspecified, not #f.
7958 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
7960 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
7962 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
7964 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
7966 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7968 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
7969 This is necessary on Ultrix, and doesn't hurt portability.
7971 * Makefile.in (dist-dir): New target, implementing a new dist system.
7972 (installed_h_files): Put in alphabetical order.
7973 Remove duplicate entries for markers.h and unif.h.
7974 (c_files): Remove duplicate entries for markers.c.
7975 (ancillary): Renamed from anillery; all uses changed. Remove
7976 PLUGIN; it's a directory, and needs special treatment in dist-dir.
7977 Remove all the ../doc/* files; doc/Makefile.in handles that.
7979 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
7981 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
7982 every if must have an else, or else the whole command has a
7983 non-zero exit code whenever the if's condition is false.
7985 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
7987 * posix.c: include string.h.
7989 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7991 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
7994 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
7995 Remove leading % from scheme names.
7996 Do not return error values, call SCM_SYSERROR or similar.
7998 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8000 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8002 * struct.c (scm_init_struct): new file.
8004 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8006 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8007 (scm_list_head): added list-head for rapidly chopping argument
8008 lists off of longer lists (and similar).
8010 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8012 * objprop.c (scm_object_property): assq the cdr of the whash
8013 handle for obj, not the handle itself.
8015 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8017 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8018 weak hash tables last of all marking to avoid an obscure gc bug.
8019 WARNING: circular lists stored in a weak hash table will hose us.
8021 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8023 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8024 new functions similar to scm_substring_move_left_x and
8025 scm_substring_move_right_x.
8027 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8029 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8032 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8034 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8036 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8038 * strports.c (scm_strprint_obj): convenience function. C for
8039 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8041 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8042 removed to a separate library
8044 * init.c (scm_boot_guile): copied from guile-tcl.c.
8045 Initialization specific to tcl interpreters removed.
8047 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8049 * ports.c (scm_ports_prehistory): size malloced here doesn't
8050 matter so long as it is non-0 (got rid of "* 4").
8052 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8054 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8055 since its definition was bogus).
8057 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8059 * mallocs.[ch]: back again (for rx at least).
8061 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8063 * ports.c: removed functions relating to the mapping between ports
8064 and descriptors. (That stuff is unix-specific and should be collected
8065 in a separate library).
8067 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8068 (Tom Mckay@avanticorp.com)
8070 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8072 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8073 handled correctly (SCM_FREEP was applied to them) -- test for
8074 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8075 being overwritten with #f. (brown@grettir.bibliotech.com)
8077 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8079 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8082 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8084 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

8089 * list.c (scm_last_pair): map '()=>'()
8091 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8093 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8094 Generalized assoc and hash-table functions.
8095 Factored pairs.c into multiple files.
8097 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8099 * gscm.c (gscm_run_scm): got rid of objprop.
8101 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8103 * genio.c (scm_getc):
8104 NOTE: fgetc may not be interruptable.
8106 * procprop.c (scm_stand_in_scm_proc):
8107 NOTE: don't use a alist here.
8108 (scm_set_procedure_properties_x): fix type checking throughout this file.
8110 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8112 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8113 after freeing part of the port table.

8117 * strports.c (scm_mkstrport):
8118 * vports.c (scm_make_soft_port): allocate a port table entry
8119 (possibly triggering gc) before setting the tag of the corresponding
8122 * pairs.c (scm_delq_x): never throw an error.
8124 * vectors.c (scm_make_vector): made the default vector fill argument
8125 into '() (much more useful than the previous value, "#unspecified")
8127 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8129 * ports.c (scm_add_to_port_table): Added fields
8130 to port table entries: file_name, line_num, col.
8131 Update these in open_file, gen_getc and gen_ungetc.
8132 Added procedures to access those fields.
8134 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8136 * procs.c (scm_make_subr_opt): new entry point for making
8139 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8141 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8143 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8145 * numbers.c (scm_exact_p): This function no longer
8146 implements "integer?".

8150 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8151 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8152 and the stats reporting formerlly built into repl.

8155 GC statistics keeping moved to gc.c.
8156 Other statistics keeping can be done from Scheme.
8157 REPLS are now written in Scheme.
8159 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8161 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8162 conservatively marked objects).
8164 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8166 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8168 * feature.c (scm_compiled_library_path): moved here from repl.c.
8169 This file is for stuff relating specifically to Scheme libraries
8172 * eval.c (scm_m_define): don't give warning about redefinition, don't
8175 NOTE: this should throw a resumable exception with parameters --
8176 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8178 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8180 * error.c: scm_warn eliminated.

8192 between the call to procedurep and use.
8194 * error.c (scm_everr):
8196 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8199 * strports.c: don't reveal the port's string to the caller
8200 because it changes size.
8202 (stputc stwrite): check/change the strings length with interrupts
8205 * objprop.c (scm_set_object_property_x &c): use the generic
8206 hashing functions and be threadsafe.
8208 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8209 (per suggestion jaffer@gnu.ai.mit.edu).
8211 * mbstrings.c (scm_multi_byte_string): guard against argument list
8214 * strings.c (scm_make_string): loop cleanup
8216 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8219 * weaks.c (scm_weak_vector): guard against argument list
8222 * variable.c (scm_builtin_variable): check for/make a built-in
8225 * vectors.c (scm_vector): while filling the new array,
8226 guard against a list of fill elements that grows after
8227 the vector is allocated.
8229 * hashtab.c -- new file: general hash table
8230 functions. hash, hashq, hashv, hashx.
8232 * tags.h: made wvect an option bit of vector.
8234 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
8236 * symbols.c: made the basic symbol table operations atomic.
8238 * root.c &c.: collected stack-specific global state.
8239 linum/colnum etc *should* be port-specific state.
8241 * struct.c (scm_init_struct): init the first struct type during
8242 initialization to fix a race condition.
8244 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8245 object, not in a global.
8246 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8248 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8249 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8251 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8252 and C symbols to begin with SCM_ or scm_.
8254 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
8256 * gsubr.c (scm_gsubr_apply): statically allocate the
8257 array of arguments (bothner@cygnus.com).
8259 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
8261 * scmsigs.c: Simplified to use async rountines.
8263 * async.c: New support for interrupt handlers.
8265 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8267 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8268 set the multi_byte flag correctly in symbols. This is wrong.
8269 intern_obbary_soft and msymbolize should take an extra parameter.
8270 Also, weird multibyte symbols don't print correctly.
8271 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8274 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8276 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
8277 use the system symhash. == #t means create an uninterned symbol.
8279 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8281 * strings.c (scm_make_shared_substring): build'em.
8282 It might better to keep a table of these and use one
8283 less cons-pair per shared-substring.
8285 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
8287 * strings.c (scm_string_shared_substring): create shared

8292 * print.c (scm_iprin1): print substrings as their non-substring
8293 counterparts (dubious).

8298 * hash.c (scm_hasher): hash RO and MB strings as bytestrings.
8300 * eval.c (SCM_CEVAL): self-evaluate RO and MB strings.
