3 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
6 * eval.h: Added prototypes for multi language support functions.
8 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
9 improper lists in the low-level representation, since that will
10 cause a begin to be prepended at macro expansion.
12 * eval.c (scm_cons_source): Version of cons which copies source
13 properties from an existing cell.
14 (scm_m_quote, scm_m_begin, scm_m_if, scm_m_set_x, scm_m_and,
15 scm_m_or, scm_m_case, scm_m_cond, scm_m_lambda, scm_m_letstar,
16 scm_m_do, scm_m_letrec, scm_m_let, scm_copy_tree, SCM_CEVAL): Use
19 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
20 procedure source before calling scm_unmemocopy instead of faking
23 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
25 Ported `internal defines' fix from SCM. Original ChangeLog entry:
27 1998-07-09 Radey Shouman <radey@colorage.com>
29 * eval.c (ceval_1): Modifications to allow rewriting of interal
30 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
31 body of which it is the CAR is macro expanded by m_expand_body,
32 which rewrites internal DEFINE.
34 (m_expand_body): Added.
36 (m_macroexp1): Added argument to control error checking:
37 m_expand_body may speculatively expand forms in the wrong
38 environments. Made argument number checks conditional on
41 (m_body): Added, error checks bodies and inserts the ISYM tokens.
43 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
46 (m_cond): (m_case): (m_quote): Modified to avoid destructively
47 changing their argument forms. Since m_expand_body
48 speculatively macro expands forms the process must be
51 (m_ident_eqp): Fixed to use proper environment.
53 (renamed_ident): Added DEFER_INTS_EGC.
55 Added prototypes for static functions.
61 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
62 is false, do not produce an error for unbound variables, return a
63 pointer to cell_undef instead.
65 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
69 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
70 destructively changing their argument forms. Since m_expand_body
71 speculatively macro expands forms the process must be reversible.
73 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
74 SCM_IM_LET introduced by named lets.
76 (scm_m_letstar): Use scm_m_body instead of bodycheck.
78 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
79 scm_letrec. scm_letrec1 does not check for a null binding and
80 takes an additional argument to specify the ISYM of the body. Use
81 scm_m_body instead of bodycheck.
83 (scm_m_let): Use scm_m_body instead of bodycheck.
85 (scm_m_expand_body, scm_macroexp): New.
87 (unmemocopy): Account for ISYMs introduced by scm_m_body.
89 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
90 check=1. Throw error for internal defined that have not been
91 rewritten by scm_m_expand_body.
93 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
94 Removed prototype for SCM_APPLY.
96 * tags.h: Added extern declaration of scm_isymnames.
98 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
100 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
102 * lang.c: New file: Beginning of multi-language support.
104 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
106 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
107 (scm_dynamic_wind): Added argument checking for the after guard so
108 that we don't add garbage on the dynwind chain.
109 (scm_swap_bindings): Added.
111 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
112 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
113 (scm_isymnames): New isyms for multi-language support.
115 * eval.c (scm_nil, scm_t): New symbols.
116 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
117 forms for multi-language support.
119 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
121 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
123 Renamed functions in the random function library interface
124 from scm_i_XXX --> scm_c_XXX.
126 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
128 * ports.c (scm_putc): fix line-buffering.
130 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
132 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
133 scm_set_ptob_XXX --> scm_set_port_XXX.
135 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
137 * ports.c, ports.h (scm_make_port_type): New interface for
138 creation of port types (replaces scm_newptob). Just as for the
139 smobs, we need to separate the internal representation of smob
140 types from the interface, so that we easily can add new fields and
141 rearrange things without caring about backward compatibility.
142 This change was forced by the need in GOOPS to create classes
143 representing port types.
144 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
145 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

154 (void_port_ptob, print_void_port, close_void_port, noop0):
155 Removed. Removed #include "genio.h" Added #include "objects.h",
158 * fports.c (prinfport): Moved code from ports.c.
160 (scm_fptob): Removed. Instead use new interface.
161 (scm_make_fptob): Added. (Need to create basic ports in a
162 specific order in ports.c.)
164 * strports.c (scm_stptob, prinstpt, noop0): Removed
165 (scm_make_stptob): Added.
167 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
168 (scm_make_sfport): Added.
170 * filesys.c (scm_dir_print): Don't use the port printing code.
171 Instead provide specific directory printer.
173 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
175 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
178 * smob.c (scm_smob_print): Handle non-existing type name nicely.
179 Removed #include "genio.h"
181 * objects.c (scm_make_port_classes): New function ptr.
183 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
185 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
187 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
188 allow the 1st argument to be a fdes or filename as well as a

191 * filesys.c (scm_truncate_file): removed.
193 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
195 * readline.c, readline.h: Removed.
197 * objects.c, objects.h (scm_port_class): Added.
198 (scm_class_of): Look up port class in scm_port_class.
199 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
200 SCM_INOUT_PCLASS_INDEX): Added.
203 * Makefile.am: Removed genio.c, genio.x.
207 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
209 * init.c: Make sure that scm_post_boot_init_modules is called only
210 once. (Important when using a dumped image.; Thanks to Bernard
213 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
215 * guardians.c (scm_guardian_zombify): Separate scanning for
216 zombies from marking the pairs of the free list.
218 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
219 use the macros. (Thanks to Michael Livshin.)
221 * eval.c (scm_m_lambda): Let bodycheck check the body of the
222 lambda. Let your sins be purified by the blood of the lambda.
223 (Thanks to Eric Hanchrow.)
225 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
226 (Thanks to Valdis Kletnieks.)
228 Fixes for EMX from Mikael Ståldal.
230 * filesys.c: #include <io.h>, if we have it.
231 * scmconfig.h.in: Regenerated.
233 * stime.c (ftime): Delete declaration for this function --- let
234 the system supply it.
236 Cleanups from John Bley.
238 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
240 * gsubr.c: Don't include "gsubr.h" twice.
242 Cleanups for compilation on Irix 6, from David Kaelbling.
244 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
245 regex_t pointer. This is what the callers have, mostly.
246 (scm_regexp_exec): Don't forget to pass the `rx' argument to
247 scm_regexp_error_msg.
249 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
250 int. That way, if we get a warning on this line, it's more likely
251 that we're really missing bits we care about.
253 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
256 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
257 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
258 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
259 cast at all is more appropriate in every case. At the moment, we
260 assume everywhere that SCM is an integral type anyway.

264 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
265 read_pos after scm_fill_buffer.
267 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
270 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
271 fports.c (fport_fill_buffer): implement the interface change.
273 * ports.c (scm_fill_buffer): interface change: no longer increments
274 read_pos past the character that's returned. it seems clearer to
275 leave it to the caller to decide what to do (thanks Jim).
277 * vports.c (sf_fill_buffer): put the read char into the buffer
278 as well as returning it.
280 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

287 (st_seek): don't allow string to be extended if seeking past
288 the end of a read-only port.

294 * ports.c (scm_ftruncate): throw error if offset works out negative.
296 * strports.c (st_flush): increase string size in blocks of
297 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
298 it's greater and reset read_buf_size.
299 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
300 to be maintained for output ports too (it holds the written
301 part of the string, while write_buf may have unwritten buffer
303 (st_truncate): rewritten.
304 (top of file): added a few notes.
306 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
308 Patch from Greg Badros:
309 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
310 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
311 (function pointer) argument to scm_make_gsubr and scm_make_subr
312 calls. This avoids warnings in C++ programs using guile-snarf.
314 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
316 * strports.c (st_grow_port): set pt->read_pos. set
317 pt->read_buf_size one less than pt->write_buf_size if there's
318 an unwritten char at the end of the string. similarly for
320 (st_resize_port): renamed from st_grow_port.
321 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
322 seek from read_end instead of write_end for SEEK_END.
323 (st_ftruncate): calculate current length using readbuf, not write

331 (scm_call_with_output_string, scm_strprint_obj): use
332 scm_strport_to_string.

335 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
337 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

343 and "bigneg" smob types.
345 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
346 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

440 * struct.c, struct.h:
442 In order to support different kinds of deallocation, a destructor
443 slot has been added to struct vtables. This allows for structs
444 containing pointers to other memory blocks.

563 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
565 (scm_weak_size, scm_n_weak): Deleted.
566 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
567 vectors without allocating new storage during GC, using
568 scm_weak_vectors as the head of the chain.
569 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
570 instead of stepping through an array.
571 (scm_gc_sweep): Update offset used to find start of weak vector to
573 (scm_init_storage): Set scm_weak_vectors to EOL.
575 Fix from Ken Raeburn <raeburn@raeburn.org>:
576 * gc.c (already_in_gc): New variable.
577 (scm_igc): Set and clear already_in_gc; abort if it's set at
580 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
582 Fix from Gary Houston:
583 * fports.c (local_seek): Signal an error if the seek fails.
584 * ports.c (scm_lseek): Don't check return value of port's seek
585 function; it's its job to signal an error if there's a problem.
587 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
589 * strports.c (scm_call_with_output_string): Don't include the
590 extra character at the end of the string in the result.
592 * ioext.c (scm_read_line): Switch to reading properly.
594 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
595 scmsigs.c, strports.c, vports.c: Install the sources which
596 actually correspond to the changes described below. I got the
597 ChangeLog entries and the patch from two different places...
599 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
601 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
602 it shows up as terrible performance, as we GC constantly.
604 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
605 newline. A bit faster, and definitely hairier.
606 (scm_read_line): Count newlines here instead.
608 * strings.c (scm_take_str): New function.
609 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
610 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
611 scm_take_str, to avoid copying the string.
613 Add some simple-minded support for line buffered ports.
614 * ports.h (SCM_BUFLINE): New flag for ports.
615 * init.c (scm_init_standard_ports): Request line-buffering on
616 the standard output port.
617 * * ports.c (scm_mode_bits): Recognize 'l' as a request for line
619 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
620 and there's a newline to be written, flush the port.
622 Gary Houston's open-buffer port patches:
624 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
626 * ports.c: (scm_lseek): clear buffers even if just reading current
629 * fports.c (local_fclose): call local_fflush unconditionally.
630 (various): don't use the scm_must... memory procs.
632 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
634 * ports.h (scm_port): make read_pos a pointer to const.
635 strports.c: take care of rw_active and rw_randow.
636 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
637 strports.c (scm_mkstrport): check that pos is reasonable.
638 ioext.c (scm_ftell, scm_fseek): use lseek.
639 (SCM_CLEAR_BUFFERS): macro deleted.
640 ioext.c (redirect_port: use ptob fflush, read_flush.
641 ports.h (scm_ptobfuns): add ftruncate.
642 ports.c (scm_newptob): set ftruncate.
644 * ports.c (scm_ftruncate): new procedure.
645 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
646 strports.c (st_seek, st_grow_port): new procs.
647 fports.h (scm_port): change size types from int to off_t.
648 ports.c (scm_init_ports): initialise the seek symbols here
649 instead of in ioext.c.
650 strports.c (scm_call_with_output_string): start with an empty
651 string, so seek and ftruncate can be used.
653 gdbint.c: adjust string port usage.
655 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
657 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
658 equivalent to fflush for the read buffer.
659 * ports.c (scm_newptob): set read_flush.
660 ports.c (void_port_ptob): set read_flush.
661 fports.c (local_read_flush): new proc. add to ptob.
662 strport.c (st_read_flush): likewise.
663 vport.c (sf_read_flush): likewise.
664 fports.h (struct scm_fport): remove random member. there's nothing
665 left but fdes. leaving it as a struct to allow for future changes.
666 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
667 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
668 ptob proc if the read buffer is filled.
670 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
672 * ports.h (scm_port): add a rw_random member and replace
673 reading and writing members with rw_active member.
674 SCM_PORT_READ/SCM_PORT_WRITE: new values.
676 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
678 * ports.h (struct scm_port_table): add writing and reading members
679 to replace write_needs_seek: it isn't good enough for non-fports.
680 ports.c, ioext.c, fports.c: corresponding changes.
681 (struct scm_port_table): give it a typedef and rename to scm_port.
682 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
683 corresponding changes.
685 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
687 * ports.c (scm_newptob): bugfix: set seek member.
688 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
689 and generalised to all port types.
691 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
693 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
694 signals (it was only being done for handlers installed from Scheme).
695 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
696 waiting for input caused an EINTR error from read.
698 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
700 * ports.h (struct scm_port_table): make all the char members
701 unsigned, so they convert to int without becoming negative if large.
703 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
705 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
706 with threads enabled. rename this procedure to
707 fport_wait_for_input and take a port instead of a fdes.
708 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
710 * readline.c (scm_readline): Applied a patch from Greg Harvey to
711 get readline support working again: use fdopen to get FILE objects.
713 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
715 * gc.c (scm_init_storage): install an atexit proc to flush the
717 (cleanup): the new proc. it sets a global variable which can be
718 checked by the ptob flush procs to avoid trying to throw
719 exceptions during exit. not very pleasant but it seems more reliable.
720 * fports.c (local_fflush): check terminating variable and if set
721 don't throw exception.
722 * CHECKME: that the atexit proc is installed if unexec used.
724 * throw.c (scm_handle_by_message): don't flush all ports here.
725 it still causes bus errors.
727 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
730 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
732 * ports.c (scm_char_ready_p): check the port buffer and call the
733 ptob entry if needed.
735 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
736 ptob initialisers. use it in char-ready
738 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
740 * vports.c (sfflush): modified to write a char (since softports
741 currently use shortbuf.)
743 * fports.c (scm_standard_stream_to_port): moved to init.c and
746 * init.c (scm_init_standard_ports): make stdout and stderr
747 unbuffered if connected to a terminal. with stdio they
748 were line-buffered by default.
750 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
753 * ports.h (scm_ptobfuns): change fflush return to void.
754 change flush proc definitions.
756 * strports.c (scm_call_with_output_string): get size from
757 buffer instead of port stream.
758 (st_flush): new proc.
760 * ports.h (struct scm_port_table): added write_end member,
761 as an optimisation. set it where write_buf_size is set.
763 * ports.h (struct scm_port_table): change stream from void *
764 back to SCM. SCM presumably must be large enough to hold a
765 pointer (and probably vice versa but who knows.)
766 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
768 (scm_puts): rewritten
769 * fports.c (local_ffwrite, local_fputs): removed.
770 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

781 * ports.h (scm_ptobfuns): add seek function pointer.
782 * fports.c: set it to local_seek, new procedure.
785 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
786 use ptob for seek. take ptob instead of fport arg.
788 * ports.h (struct scm_port_table): new member write_needs_seek,
789 replaces reading member in fport struct.
791 * vports.c (sfgetc): store the getted char into the buffer.
792 rename to sf_fill_buffer and install it for fill-buffer in ptob.
793 the Scheme interface is still a procedure that gets a char.
794 (scm_make_soft_port): set up the port buffer (shortbuf).
796 * fports.c (local_fgetc, local_fgets): deleted.
797 * strports.c (stgetc): likewise.
798 * ports.c: scm_generic_fgets: likewise.
800 * ports.h (scm_ptobfuns): add fill_buffer.
801 * ports.c (scm_newptob): assign it.

803 put just the string into the stream, not cons (pos stream).
804 (stfill_buffer): new proc.
806 * ports.h: fport buffer moved into port table: to be
807 used for all port types.

1077 * snarf.h (SCM_SYNTAX): Name is const.
1079 * eval.c (scm_i_let): Make this globally visible, to avoid dynamic
1080 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
1082 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1084 * numbers.c (isfinite): Define this macro if not defined: Return a
1085 non-zero value if X is finite. (From ISO C 9x standard.)
1086 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1087 (Thanks to Jon Trowbridge and Greg Harvey.)
1089 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1127 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1128 scm_misc_error when pos is a string. This allows for dispatching

1140 Most of this batch of changes is about how to deal with extended
1141 types when an object system is loaded into Guile. A nice object
1142 system is capable of representing Guile's types as class objects.
1144 For example, we want a regular expression to be of class <regex>.
1145 But regular expressions are smobs which aren't under direct
1146 control of the object system, so there has to be some mechanism
1147 which informs the object system that a new class should be created
1148 which can represent the smob type. I call this a "wrapper class".
1150 * objects.c: #include "smob.h";
1151 (scm_class_keyword): Removed. (Class is automatically created by
1153 (scm_smob_class): Array of smob classes indexed by smobnum.
1154 (scm_make_extended_class): "Plugin" function pointer for creation
1155 of wrapper classes for smob and struct types.
1156 (scm_class_of): Handle compiled closures. (Currently regarded as
1158 Use scm_smob_class to handle smob types;
1159 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1160 through scm_smob_class;
1163 * smob.c (scm_newsmob): Also create a wrapper class if
1164 scm_smob_class has been initialized.
1166 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1167 type code and smobnum.
1169 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1170 (scm_struct_table): Weak key table with auxilliary information for
1171 struct types. Currently used for names and wrapper classes.
1172 (scm_struct_ihashq): Hash function for structs.
1173 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1174 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1175 for accessing names of vtables. The record implementation in
1176 boot-9.scm currently uses the setter to record the name of record
1177 types. When the object system is initialized, it can use this
1178 information to create wrapper classes with suitable names.
1179 (scm_init_struct): Allocate scm_struct_table.
1180 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1181 (struct tags are a finite resource and we might want to restrict
1182 the use of tags to vtables only. E.g., Goops only uses tags for
1184 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1186 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1189 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1190 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1191 Used for access of struct table entries.
1193 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1194 (scm_hash_fold): New procedure. Used to process all entries in a
1195 hash table (in no particular order).
1197 Argh! For the umpteenth time I got compilation errors because of
1198 the "intuitive" name `kw'. This has to have an end:
1200 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1201 "kw" --> "keywords" everywhere.
1202 (I doubt that this will cause big compatibility problems since the
1203 application interface is unaffected.)
1205 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1207 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1209 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1210 column inums to native form.
1212 Improvement of backtraces: Introduces a new stack narrowing
1213 specifier, #t, for the inner cut. (See further in the comments in
1214 stacks.c:narrow_stack ().)
1216 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1217 (Used to flag certain system procedures which shouldn't turn up in
1220 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1221 modules which aren't "user" modules and the code of which

1225 Extract the lookup closure from an environment.

1232 * debug.c (scm_procedure_name): Use name property in the default
1235 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1237 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1239 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1240 procedure throughout.
1242 * print.c (scm_iprin1): Removed extraneous space when printing
1243 procedure-with-setters.
1245 Entity and operator setter slots were introduced as a complement
1246 to the <procedure-with-setter> type in order to support entities
1247 and operators with setters in a reasonable and efficient way.
1248 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1251 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1264 directly through the instance.
1266 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1268 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1269 scm_struct_i_flags instead of scm_vtable_index_layout!
1271 * list.c (scm_list_star): New procedure.
1273 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1354 SYMB now point to const.
1356 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1358 * print.c (scm_iprin1): Use scm_procedure_name instead of
1359 scm_procedure_property for compiled closures.
1361 * tags.h (scm_tc7_pws): New procedure type. Four representations
1362 for procedure-with-setters were considered before selecting this
1365 1. A closure where the CODE and ENV slots are used to represent
1366 the getter and a new SETTER slot is used for the setter. The
1367 original getter is stored as a `getter' procedure property. For
1368 closure getters, the CODE and ENV slots contains a copy of the
1369 getter's CODE and ENV slots. For subr getters, the CODE contains
1372 2. A compiled closure with a call to the getter in the cclo
1373 procedure. The getter and setter are stored in slots 1 and 2.
1375 3. An entity (i.e. a struct with an associated procedure) with a
1376 call to the getter in the entity procedure and the setter stored
1377 in slot 0. The original getter is stored in slot 1.
1379 4. A new primitive procedure type supported in the evaluator. The
1380 getter and setter are stored in a GETTER and SETTER slot. A call
1381 to this procedure type results in a retrieval of the getter and a
1382 jump back to the correct eval dispatcher.
1384 Representation 4 was selected because of efficiency and
1387 Rep 1 has the advantage that there is zero penalty for closure
1388 getters, but primitive getters will get considerable overhead
1389 because the procedure-with-getter will be a closure which calls
1392 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1393 <procedure-with-setter>, but together with rep 2 it suffers from a
1394 three level dispatch for non-GOOPS getters:
1396 cclo/struct --> dispatch proc --> getter
1398 This is because the dispatch procedure must take an extra initial
1399 argument (cclo for rep 2, struct for rep 3).
1401 Rep 4 has the single disadvantage that it uses up one tc7 type
1402 code, but the plan for uniform vectors will very likely free tc7
1403 codes, so this is probably no big problem. Also note that the
1404 GETTER and SETTER slots can live directly on the heap, using the
1405 new four-word cells.
1407 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

1573 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1575 * Makefile.in: Regenerated.
1577 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1579 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1580 take the address of _into; it might be a register. Just have
1581 scm_debug_newcell return the new cell.
1582 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1583 taking the address of a place to store it as an argument.
1584 * gc.h (scm_debug_newcell): Change declaration.
1585 (Thanks to Greg Harvey.)
1587 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1589 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1590 Replaces old names serial-array-copy! and serial-array-map!.
1592 * evalext.c (map-in-order): New name. Replaces serial-map.
1594 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
1596 * smob.c (freeprint): New function.
1597 (freecell): Use it to print freed objects, for slightly easier
1600 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1602 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1603 error if no source properties can be found for a frame. (Thanks
1604 to Christian Lynbech.)
1606 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1608 * objects.h: Removed slots direct_supers and direct_slots from the
1609 definitions of the rudimentary classes described by objects.h.
1611 * objects.c, objects.h (scm_entity_p): New procedure. Together
1612 with the predicates scm_procedure_p and scm_struct_p, this
1613 predicate makes it possible to differ between structs, entities
1616 * modules.c, modules.h (scm_resolve_module): New function.
1618 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1620 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1621 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1624 * objects.c (scm_entity_p): New procedure.
1626 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1627 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1629 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1631 * procprop.h (scm_i_procedure_arity): Added declaration.
1633 * procprop.c (scm_i_procedure_arity): Made global; New code to
1634 handle operators and entities.
1635 (scm_procedure_property): No need to call scm_procedure_p since
1636 scm_i_procedure_arity now does all necessary type checking.
1637 Added #include "objects.h".
1639 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1640 s_add_hook_x --> s_remove_hook_x.
1641 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1642 Added #include "procprop.h"
1644 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1645 (scm_make_hook): Optional argument defines number of arguments to
1647 (scm_make_named_hook): Take number of args as second arg.
1648 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1649 boot-9.scm for a while); First arg is the hook. The rest are
1650 arguments passed on to the hook procedures.
1652 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1654 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1655 scm_logbit_p): Do the computation in ulongs. This is not as nice
1656 as doing it in bignums, but at least it's good enough for
1657 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1659 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1660 subexpressions. (Thanks to Charbel Jacquin.)
1662 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1664 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1665 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1666 (scm_make_named_hook): New function.
1668 * feature.c: Added #include "eval.h".
1670 * modules.c (scm_make_module): Beautify the module.
1672 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1674 * modules.c, modules.h: New files: C interface to modules. (This
1675 is necessary in order to interface the object system to Guile
1676 properly. The guts of these modules will be replaced by the new
1677 module system in the future.)
1679 * init.c: Added #include "modules.h"
1680 (scm_boot_guile_1): Call scm_init_modules.
1681 (invoke_main_func): Call scm_post_boot_init_modules.
1683 * Makefile.am: Added modules.c, modules.x, modules.h.
1685 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1687 * procs.c: #include "objects.h"
1688 (scm_procedure_p): Return #t also on structs which are operators.
1690 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1691 <operator-metaclass> and <entity-class> to <standard-class>,
1692 <operator-class> and <entity> in order to conform with STKlos
1695 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1696 which isn't an operator.
1697 (SCM_APPLY): Ditto, but jump to badproc.
1699 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1701 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1702 Previously, structs implanted in code were interpreted as forms
1703 the operator of which was a gloc. We solve this by checking for
1704 the zero in the emulated vcell in the struct vtable. Since
1705 implanted structs always will look like forms with a gloc
1706 operator, execution will only be slowed down by maximally one
1707 extra test-and-branch per application.
1709 * evalext.c (scm_definedp): Removed check for isyms; Added a
1710 second optional argument: It is now possible to supply an
1711 evaluation environment in which to look for the symbol.
1713 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1715 * readline.c (scm_init_readline): Set
1716 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1718 * coop.c (coop_condition_variable_wait): Removed
1719 (coop_condition_variable_wait_mutex): Folded logic of
1720 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1721 prevent condvar signal lossage. Previously, another thread could
1722 start to run after unlocking the mutex but before putting the
1723 current thread on the wait queue. If that thread then would
1724 signal the first, the signal would be lost. (Thanks to Christian
1727 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1729 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1732 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1734 * objects.c (scm_i_make_class_object): Renamed from
1735 make_class_object; exported; error checking moved to
1736 scm_make_class_object and scm_make_subclass_object.
1737 (scm_make_class_object, scm_make_subclass_object): Use
1738 scm_i_make_class_object.
1739 (scm_make_subclass_object): Let the subclass have same metaclass
1742 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1744 * debug.c (scm_debug_options): Bugfix: Set the value of
1745 scm_stack_checking_enabled_p after setting debug options;
1746 #include "stackchk.h". (Thanks to Richard Polton.)
1748 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1750 * unif.c (scm_array_contents): removed unnecessary test for 0
1753 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1755 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1756 Replaced by macro `collect' in boot-9.scm.
1758 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1760 * eval.c (scm_copy_tree): Copy source properties if existent.
1762 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1763 don't, we may end up passing memoized source to a transformer.)
1765 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1767 * stack.c (get_applybody): Help function which lookups the first
1768 body form of the apply closure.
1769 (read_frames): Prevent the source of the first form of the apply
1770 closure from being recorded. This would only be confusing.
1772 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1773 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1775 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1777 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1779 (read_frames): Use SCM_MACROEXPP.
1781 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1783 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1784 don't contain interesting information since all arguments are
1785 present in the frame which applies the compiled closure anyway.);
1786 Skip the transformer application frames.
1788 * print.c (scm_iprin1): Print gsubrs as primitives.
1790 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1792 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1794 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1795 that we can identify these in a backtrace. (This change doesn't
1796 introduce any significant speed penalty.)
1798 * eval.c: Added note about `serial-map' using scm_map.
1800 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1801 readline options. They should reside in their own options array.
1803 * readline.c, readline.h (scm_readline_options,
1804 scm_readline_opts): Moved readline options here.
1806 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1808 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1809 SCM_ROCHARS instead of SCM_CHARS.
1811 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1812 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1814 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1816 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1817 This is quite important since the latter clears the
1818 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1819 every single character read...
1821 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1823 * print.c (scm_iprin1): Removed suspect looking (and indeed
1824 malevolent) semicolon after test for user supplied closure print
1825 procedure. (Thanks to Telford Tendys.)
1827 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1828 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1829 starting to search the list. Removed call to sloppy_mem_check.
1831 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1832 procedures: Same as scm_delq_x et al, but delete maximally one
1835 * options.c (scm_options, scm_init_options): GC-protect option
1836 values of type SCM. (Thanks to Telford Tendys.)
1838 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1840 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1841 make sure that there always is a "real" scm_lookupcar.
1843 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1845 * read.c, read.h (scm_read_opts): New read options
1846 "history-length" and "history-file".
1847 (scm_read_options): Stifle history to history length.
1849 * readline.c (scm_read_history, scm_write_history): New procedures.
1851 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1853 * eval.h (scm_macro_eval_x): Removed declaration.
1855 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1856 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1857 Renamed and made global.
1859 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1860 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1862 * evalext.c, evalext.h: New files. Contain non-R5RS things
1863 having to do with evaluation.
1865 * evalext.c (scm_serial_map): New procedure: Version of `map'
1866 which guarantees that the procedure is applied to the lists in
1868 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1869 returns a list of the results of the body forms instead of the
1870 result of the last body form.
1871 (scm_definedp, scm_m_undefine): Moved from eval.c
1873 * evalext.h (scm_m_sequence_to_list): Added declaration.
1875 * macros.c, macros.h: New files.
1876 (scm_procedure_to_syntax, scm_procedure_to_macro,
1877 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1878 scm_macro_name, scm_macro_transformer): Moved from eval.c
1879 (scm_make_synt): Moved from eval.c
1881 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1883 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1886 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1888 * debug.c, print.c: Added #include "macros.h".
1890 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1892 This change adds the ability to use `unread-char' multiple times
1893 without interspersed reads and adds the new procedure
1894 `unread-string'. The change is optimized for the common case of
1895 unreading a single character. This is also the reason behind the
1896 choice to store characters in the port itself: in most cases no
1897 extra malloc is required.
1899 The amount of code in some macros in ports.h has been increased to
1900 the extent that they would fit better as C functions, but, since
1901 this code belongs to the port representation, such functions
1902 should be placed in ports.c which would cause calls back and forth
1903 between ports.c and genio.c. That is not good for performance.
1904 Also, keeping them as macros allows the compiler to do some
1905 optimizations which are needed to make the current interface
1906 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1908 One benchmark (Guile startup time) indicates an increase of
1909 loading speed of 1%. Another (reading (using `read') boot-9.scm
1910 10 times) shows no change in performance.
1912 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1913 made to find a beautiful solution.)
1915 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1916 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1917 character. (SCM_CLRDY clears all.)
1918 (SCM_N_READY_CHARS): New macro: Returns number of unread
1919 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1920 (struct scm_port_table): New fields: `entry' contains port table
1921 index, `cp' points to last unread char, `cbuf' is the buffer for
1922 unread chars, `cbufend' points after end of the character buffer.
1924 * ports.h, ports.c (scm_unread_string): New procedure.
1925 (scm_grow_port_cbuf): New function.
1927 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1929 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1930 to read unread characters. Use SCM_TRY_CLRDY instead of
1933 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1935 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1937 * genio.c, genio.h (scm_ungets): New function.
1939 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1942 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1944 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1945 declarations. (Thanks to Russ McManus.)
1947 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1949 * numbers.c (num2long): As a software archeologist, I'm proud of
1950 this finding! :) Preliminary dating suggests an almost 4 year old
1951 remnant from the SCM ancestor. The sample has been removed from
1952 the finding site and is now safely stored in the repository.
1954 * numbers.h: Removed prototype for num2long.
1956 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1958 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1959 array as second arg.
1960 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1961 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1962 * gh.h: Updated and added prototypes.
1964 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1966 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1968 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1970 * guile-snarf.in: Never generate an empty file. (Thanks to
1973 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1974 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1975 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1976 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1977 gh_new_procedure5_0): Specify argument types, to appease C++
1978 compilers. (Thanks to Brad Bowman.)
1980 Bug reports from Russ McManus:
1981 * guile-snarf.in: If the CPP environment variable is set, use that
1982 as the C preprocessor, instead of the preprocessor autoconf
1984 * snarf.h (SCM_PROC): Cast the function pointer passed to
1985 scm_make_gsubr, to satisfy C++.
1987 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
1988 Use the handler passed, instead of ignoring it and using
1989 gh_standard_handler. (Thanks to Etienne Bernard.)
1991 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
1993 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
1996 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2016 * script.c (scm_compile_shell_switches): Define
2017 use-emacs-interface in the root module, so the repl code can see
2018 it. See today's change to top-repl in ice-9/boot-9.scm.
2020 * filesys.c (set_element, get_element): Make sure that `element'
2021 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2022 Boekemeier and Jorgen "forcer" Schaefer.)
2024 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2026 * chars.c (scm_charnames): In ASCII character name table, make
2027 newlines print as #\newline by default, not #\nl.
2029 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2030 alphabetical order. Oh thrills. But it helps me know how far
2031 along in the compilation I am.
2032 * Makefile.in: Regenerated.
2034 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2036 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2037 #bytes(...) to #y(...), and syntax for short vectors from
2038 #short(...) to #h(...). This may seem nutty, but, like the other
2039 uniform vectors, byte vectors and short vectors want to have the
2040 same print and read syntax (and, more basic, want to have read
2041 syntax!). Changing the read syntax to use multiple characters
2042 after the hash sign breaks with the conventions used in R5RS and
2043 the conventions used for the other uniform vectors. It also
2044 introduces complexity in the current reader, both on the C and
2045 Scheme levels. (The Right solution is probably to change the
2046 syntax and prototypes for uniform vectors entirely.)
2048 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2050 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2051 (Thanks to Jorgen "forcer" Schaefer.)
2052 * ports.h (SCM_NOFTELL): New flag.
2053 * fports.c (local_fgets): If it's set, use the generic fgets.
2054 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2056 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2058 * script.c (scm_compile_shell_switches): Add handling of -q switch
2059 (inhibit loading of user init file).
2060 (scm_shell_usage): Add usage text for -q switch.
2061 (scm_compile_shell_switches): Always load user init file first if
2062 it is loaded at all.
2064 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2066 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2067 and is now broken under NetBSD. I can't fathom what it's trying
2068 to do, so I've replaced it with something that I do understand,
2069 which seems to work, and which isn't broken on NetBSD. "Progress?
2070 You Decide." (Thanks to Perry Metzger.)
2072 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2073 signed/unsigned comparison.
2075 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2077 Warning fixes from Greg Harvey:
2078 * unif.c (scm_array_set_x): initializer for pos
2079 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2080 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2081 initializers for field_type, since EGCS so desparately wants to
2083 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2084 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2085 when GUILE_DEBUG is defined.
2086 * dynwind.h (scm_wind_chain): Same.
2087 * ports.h (scm_pt_size, scm_pt_member): Same.
2088 * print.h (scm_current_pstate): Same.
2089 * procs.h (scm_make_cclo): Same.
2091 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2093 Handle short and long long uniform arrays properly. (Thanks to
2095 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2096 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2097 scm_tc7_llvect (long long vectors).
2099 Change the way libguile and boot-9.scm are timestamped, to try to
2100 get rid of these spurious mismatch warnings. Now both
2101 libguile/versiondat.h and ice-9/version.scm are generated directly
2102 by the configuration process, rather than having version.scm
2103 generated directly, and libguile/versiondat.h generated by the
2104 Makefile, which is generated by configure. It seems that
2105 sometimes the Makefile would change, but versiondat.h depends on
2106 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2107 * Makefile.am (versiondat.h): Target removed; this is generated
2108 directly by the configure script now.
2109 (BUILT_SOURCES): Remove versiondat.h.
2110 * versiondat.h.in: New file, transformed by the configure script
2112 * Makefile.in: Regenerated.
2114 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2115 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2116 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2117 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2118 if we want to use them in a header file some day, we can. (Thanks
2119 to Michael Livshin.)
2121 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2122 SCM numbers, so we won't have rollover problems; the range of a
2123 signed long in milliseconds is about 25 days. (Thanks to Karl
2126 Don't redefine sleep and usleep; fix this problem now.
2127 * coop.c (sleep, usleep): Remove declarations; we don't use or
2128 redefine these any more.
2129 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2130 job of usleep and sleep in a thread-friendly way. We can use
2131 these in the rest of Guile. Define versions for systems both with
2132 and without iselect.
2133 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2134 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2135 we're just using it, not redefining it, we can use a K&R style
2137 (sleep): Declare this, too, if the system hasn't.
2138 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2139 scm_uthread_sleep if they're available; otherwise, just call the
2141 * scmconfig.h.in: Regenerated.
2143 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2145 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2147 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2149 * threads.c: Doc fix.
2151 The argument type of usleep varies from system to system,
2152 as does the return type. We really shouldn't be redefining usleep
2153 at all, but I don't have time to clean that up before the 1.3.
2154 release. It's on the schedule for afterwards. (Thanks to Julian
2156 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2158 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2159 * scmconfig.h: Regenerated.
2161 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2162 right way to handle system variation. Autoconf's approach is the
2164 * simpos.h (scm_software_type): Declaration deleted.
2166 * script.c (scm_find_executable): Don't test if unix is #defined
2167 here; first, NetBSD doesn't #define it, and second, it's the wrong
2168 way to go about these things. (Thanks to Perry Metzger.)
2169 (dld_find_executable): Delete this MSDOS support code. This isn't
2170 the way we want to support this; it needs to be rethunk at a
2173 * genio.c (scm_do_read_line): Don't just politely check that the
2174 line was either non-empty or EOF. Abort if it's empty and not
2177 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2179 * scmconfig.h.in: Regenerated.
2181 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2184 * genio.c (scm_do_read_line): Count lines correctly when the file
2185 doesn't end in a newline.
2187 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2189 * genio.c (scm_do_read_line): Maintain the line count correctly.
2190 (Thanks to Harvey J. Stein and Greg Harvey.)
2192 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2195 * numbers.c (big2str): Protect t from garbage collection until
2196 we're done. (Thanks to Gary Houston.)
2198 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2200 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2202 * Makefile.in: Regenerated.
2204 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2205 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2208 Do magic to mix reads and writes on stdio FILE-based ports.
2209 (Thanks to Christian Lynbech.)
2210 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2212 (pre_read, pre_write): New functions.
2213 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2214 local_fputs): Call them.
2215 (local_fflush): Mark the port as ready for reading and writing.
2216 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2217 flags on new port objects. This might not be accurate --- who
2218 knows what state the FILE * is in when we get it --- but it won't
2219 do extraneous calls to fflush or fseek, so it's no worse than the
2220 behavior before this change.
2221 * ports.h: Add comment.
2223 Centralize the creation of port objects based on stdio FILE * in
2224 fports.c; don't just throw them together anywhere.
2225 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2226 what the rest of Guile wants. Don't set the revealed count;
2227 that's only appropriate for stdin, stdout, stderr.
2228 (scm_standard_stream_to_port): This function does set the revealed
2230 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2231 not scm_stdio_to_port.
2232 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2233 * fports.c (scm_open_file): Same.
2234 * posix.c (scm_pipe): Same.
2235 * socket.c (scm_sock_fd_to_port): Same.
2236 * ioext.c (scm_fdopen): Same.
2237 (scm_freopen): Moved from here to...
2238 * fports.c (scm_freopen): ... here. This is really something that
2239 munges the internals of an fport, so it should go here.
2240 * fports.h (scm_stdio_to_port): Adjust prototype.
2241 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2242 * ioext.h (scm_freopen): Prototype removed.
2244 * filesys.c (set_element, get_element): This can work on both pipe
2245 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2248 * scmconfig.h.in: Regenerated.
2250 Change the definition of the functions in scm_ptobfuns so that
2251 they get passed the port object, not the port's stream.
2252 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2253 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2254 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2255 Pass the port itself to the scm_ptobs function.
2256 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2257 scm_generic_fgets): Same.
2258 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2259 getc_void_port, fgets_void_port, close_void_port): Just change the
2260 argument names; these functions don't really do anything.
2261 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2262 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2263 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2264 Also, use prototyped definitions, and get rid of the extra
2266 (scm_fptob, scm_pipob): We don't need casts here any more.
2267 * strports.c (prinstpt): Use prototype declarations.
2268 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2269 and use SCM_STREAM to get the string info. Also, use prototyped
2270 definitions, and get rid of the extra declarations.
2271 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2274 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2275 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2277 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2278 scm_fgets, for consistency.
2279 (scm_fptop, scm_pipob): References updated.
2281 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2283 Include the source location in error messages for scripts.
2284 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2285 stack is still there when we catch the error.
2286 * throw.c (handler_message): If we are handling an error with a
2287 message, then put together the proper arguments and call
2288 scm_display_error, instead of scm_display_error_message. That
2289 displays source location, if it can find it.
2291 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2293 * gc.c (scm_unprotect_object): Change this so that calls to
2294 scm_protect_object and scm_unprotect_object nest properly.
2295 (scm_protect_object): Doc fixes.
2297 * strings.c (scm_string_set_x): Require the argument to be a
2298 writable string, not a substring or a symbol.
2299 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2300 (Thanks to John Redford and Charbel Jacquin.)
2302 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2304 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2306 * eval.c (safe_setjmp): Remove this misunderstanding.
2307 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2310 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2312 * libguile.h: Mark these as C declarations, for compilation by C++
2315 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2316 __cplusplus clause. I seriously doubt this ever worked the way
2317 the author seems to have intended.
2319 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2321 Utterly needless cleanups to hopelessly messy code.
2322 * ports.c: Doc fixes.
2323 (scm_fflush): Moved to ...
2324 * genio.c (scm_fflush): ... here, amongst all the other port
2325 method invocation functions.
2326 * genio.h, ports.h: The prototype moves too.
2328 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2330 * backtrace.c (display_error_body): The current frame does not
2331 always have a parent frame; consider a function called directly
2332 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2335 * alloca.c (alloca): Undo yesterday's changes, and simply call
2336 malloc directly for storage, and abort if we don't get what we
2337 want. The situation is much simpler --- just call malloc. Emacs
2338 has bizarre/evil requirements (signal handlers might malloc unless
2339 you set this global flag, so you have to set the flag around all
2340 calls to malloc) which we are certainly not going to conform to,
2341 so we can do the simple and obvious thing.
2343 * coop.c (coop_condition_variable_wait): Make this function
2344 static. It's only useful internally --- you should never just
2345 wait on a condition variable.
2346 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2348 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2350 * unif.c (scm_array_set_x): Accept any kind of number as an
2351 element for a uniform vector of doubles. This is more consistent
2352 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2354 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2355 works; I can't conveniently test it myself. (Thanks to Dvid
2356 Tillman for the bug report.)
2358 * init.c: Doc fixes.
2360 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2361 from here, not from scm_compile_shell_switches (which is a pretty
2362 dumb place to do it).
2363 (scm_load_startup_files): New function.
2364 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2365 * script.c (scm_compile_shell_switches): Don't load the startup
2367 (scm_ice_9_already_loaded): Variable moved.
2368 * init.c (scm_load_startup_files): Prototype for new function.
2369 * gh_init.c (gh_enter): Doc fix.
2371 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2373 Some anti-warning changes from Greg Harvey.
2374 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2375 warnings when it doesn't understand our NORETURN declarations in
2377 * posix.c (scm_mknod): Similar.
2379 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2381 * posix.c (scm_getpwuid): If we can't find an entry, return our
2382 own message, instead of using scm_syserror --- the getpwMUMBLE
2383 functions don't set `errno' to anything interesting.
2385 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2387 Get rid of warnings from the cooperative threading system.
2388 * threads.h (scm_single_thread_p, scm_yield,
2389 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2390 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2391 scm_wait_condition_variable, scm_signal_condition_variable): Add
2392 prototypes for these Scheme-visible functions.
2393 * coop-defs.h (coop_next_runnable_thread,
2394 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2395 Prototypes for these here, even though they're from iselect.c.
2396 (coop_condition_variable_wait, coop_join): Add prototypes.
2397 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2398 scm_threads_free_condvar): Make these smob functions static.
2399 * coop-threads.h (coop_init): Give this a real prototype.
2400 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2401 (coop_next_runnable_thread): No need to provide prototype; it's in
2404 * scmconfig.h.in: .detarenegeR
2406 * iselect.c, threads.c: Doc fixes.
2408 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2410 * Makefile.in: Regenerated with a patched automake, to get
2411 dependency generation right when using EGCS.
2413 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2414 warning. (Thanks to Robert Pluim.)
2416 * inet_aton.c (inet_aton): Reassure the compiler that the
2417 arguments to the <ctype.h> macros are all unsigned characters, not
2420 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2422 Getting rid of more warnings...
2423 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2424 today's change to ../configure.in.
2425 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2426 * scmconfig.h.in: Regenertaded.de.,.__
2427 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2428 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2431 * readline.c: Doc fix.
2432 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2433 * readline.h (scm_filename_completion_function): Add prototype.
2434 (scm_init_readline): Make this into a prototype.
2436 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2437 declare this, instead of calling scm_make_subr manually.
2439 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2441 * readline.h (scm_init_readline): Add prototype for this.
2442 (scm_init_readline): Make this a real prototype.
2444 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2446 Warning fixes from Maciej Stachowiak:
2447 * backtrace.h (scm_display_application, scm_backtrace): Add
2449 * debug.c (scm_m_start_stack): Make this function static.
2450 * fluids.h (scm_fluid_p): Add prototype.
2451 * procprop.c (scm_i_procedure_arity): Make this function static.
2452 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2453 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2454 * root.h (scm_dynamic_root): Add external prototype.
2455 * scmsigs.h (scm_usleep): Add external prototype.
2456 * script.h (scm_init_script): Use prototype, not K&R decl.
2457 * stacks.h (scm_stack_id): Add external prototype.
2458 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2460 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2462 * gh.h: took out the definitions of vset and vref, since they are
2463 replaced by the proper vector routines that correspond to the R4RS
2466 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2468 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2469 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2470 third argument, a C expression that should result in a SCM value,
2471 which is used to initialize the variable. Reimplemented
2472 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2475 * version.h (scm_libguile_config_stamp): Add prototype.
2476 (From Maciej Stachowiak.)
2478 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2480 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2481 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2483 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2485 * print.c (scm_iprin1): Rather than having one i, and using it in
2486 several places, declare a fresh i local to each block where it is
2487 used, and give it a signedness appropriate to its use in each case.
2488 (scm_iprlist): Same.
2490 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2491 comparison warnings.
2493 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2494 signed/unsigned clashes.
2496 * posix.h (scm_tmpnam): Added prototype.
2498 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2499 scm_make_subclass_object): Add external prototypes.
2501 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2502 comparison is okay here.
2504 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2506 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2507 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2509 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2512 * load.c (swap_port): Make this function static.
2514 * load.c (scm_search_path): Make max_path_len and max_ext_len
2515 unsigned, since they're compared against string sizes.
2517 * load.c (init_build_info): Make i unsigned.
2519 * ioext.h (scm_read_line): Add prototype.
2521 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2522 scm_hash_fn_remove_x): Make hash bucket index local variable k
2523 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2524 accurately as possible.
2526 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2527 comparisons, and range checking to make sure those casts are
2530 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2531 signed/unsigned comparisons.
2533 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2534 avoid signed/unsigned comparisons.
2535 * smob.h (scm_numsmob): Change extern declaration to match.
2537 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2538 avoid signed/unsigned comparisons.
2539 * ports.h (scm_numptob): Change extern declaration to match.
2540 (scm_current_load_port, scm_set_port_line_x,
2541 scm_set_port_column_x): New prototypes.
2543 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2544 test code, and it causes warnings.
2546 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2547 gh_uniform_vector_ref): Added prototypes.
2549 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2550 debugging support unconditionally. That's backtrace.c, stack.c,
2551 debug.c, and srcprop.c.
2552 (EXTRA_libguile_la_SOURCES): Omit those from here.
2553 * Makefile.in: Regenerated.
2555 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2557 * options.c (scm_options): Bugfix: Allow empty list of options!
2559 * debug.c, debug.h (scm_single_step): Removed.
2560 (scm_with_traps): New procedure. This procedure could easily be
2561 written in Scheme but needs to be highly optimized.
2563 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2565 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2566 Check SCM_TRAPS_P before trapping.
2568 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2570 Changes to avoid signed/unsigned comparison warnings.
2571 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2572 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2573 so they can have appropriate types for each application. Make i
2574 signed. Use initializers in some spots. I'll probably pay for
2576 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2577 (scm_must_realloc): Make nm unsigned.
2578 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2579 (scm_init_storage): Use prototype-style definition, and make the
2581 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2582 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2584 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2585 avoid signed/unsigned comparison warnings, and because the return
2586 value of readlink may be -1. Don't bother casting the third
2587 argument to readlink.
2589 * filesys.c (scm_dirname, scm_basename): Move these to their own
2590 page, at the end of the file.
2591 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2593 * eval.h (scm_eval_options_interface): Add external prototype for this.
2594 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2596 * eval.c (scm_lookupcar1): Make this static.
2598 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2599 Make these prototype declarations, not K&R-style.
2601 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2602 unsigned comparison warning.
2604 * appinit.c: File removed. It had a single function in it, empty,
2605 whose reason for existence is explained in no documentation or
2606 comment. I think it's there as a default for some Tcl-style
2607 initialization, but Tcl abandoned that approach a while ago.
2608 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2609 (BUILT_SOURCES): Remove appinit.x.
2610 * Makefile.in: Regenerated.
2612 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2614 * Makefile.in: Regenerated using the last public version of
2615 automake, not the hacked Cygnus version.
2617 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2619 Remove Totoro kludge.
2620 * Makefile.in, scmconfig.h.in: Regenerated.
2621 * init.c, readline.c: Don't check if TOTORO is #defined.
2623 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2625 * Makefile.am: Adjust for new thread configuration system.
2626 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2627 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2629 (THREAD_LIBS): Definition deleted; automake will generate such
2630 things automatically.
2631 * Makefile.in: Regenerated.
2633 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2635 Simplify smob and port marking; set the mark bit in the generic
2636 marking code, and make marker routines only responsible for
2637 turning up outgoing pointers.
2638 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2639 before calling the marking function. Don't call the marking
2640 function if it's zero.
2641 * markers.c (scm_mark0): Just return #f. This function isn't
2642 necessary at all now, but it's harmless to call it. We'll leave
2643 it in so other folks' code doesn't croak at link time.
2644 (scm_markcdr): Don't call SCM_SETGC8MARK.
2645 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2646 * dynl.c (mark_dynl_obj): Same.
2647 * root.c (mark_root): Same.
2648 * srcprop.c (marksrcprops): Same.
2649 * unif.c (markra): Same.
2650 * variable.c (scm_markvar): Same.
2651 * ports.c (scm_markstream): Same.
2652 (void_port_ptob): Specify zero for our marking function.
2653 * debug.c (debugobjsmob): Same.
2654 * dynwind.c (guardsmob): Same.
2655 * filesys.c (dir_smob): Same.
2656 * fluids.c (fluid_smob): Same.
2657 * fports.c (scm_fptob, scm_pipob): Same.
2658 * mallocs.c (mallocsmob): Same.
2659 * regex-posix.c (regex_t_smob): Same.
2660 * smob.c (freecell, flob, bigob): Same.
2661 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2662 * throw.c (jbsmob, lazy_catch_funs): Same.
2664 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2666 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2667 scm_copy_tree on code in order not to let memoized code to leak
2668 out. Thus, scm_copy_tree needs to copy vectors as well since
2669 quasiquote can introduce evaluated code also inside vector
2672 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2674 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2676 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2677 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2680 * unif.c: Say that ivect and uvect are of type signed and unsigned
2681 long instead of int in commentary so that it correctly describes
2684 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2686 * stime.c: Removed declaration of strptime. (It should be
2687 declared by the system headers. If it turns out that some systems
2688 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2690 * stime.h: Renamed TIMEH --> STIMEH
2692 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2693 to increase portability, don't use structure assignment.
2694 (Thanks to Nicolas Neuss.)
2696 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2698 (finalize_fd_sets): Added empty statement after last case label.
2699 (Thanks to Nicolas Neuss.)
2701 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2704 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2706 * init.c, readline.c: OK, I won't have these readline.x bug
2707 reports anymore. We've had them since April. The current reason
2708 is a completely unintelligible failure of totoro.red-bean.com to
2709 do the test for rl_getc_function in libreadline correctly. This
2710 kludge overrides the test if we're on totoro so that the snapshot
2711 generation process can work.
2713 * readline.c: Define a strdup replacement if not existent on system.
2715 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2717 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2718 This change makes scm_make_vector R5RS compatible. We cannot keep
2719 the third argument since people want to be able to deduce the form
2720 of the C function call only by looking at R5RS. (At the same time
2721 we have removed some unnecessary complexity!)
2723 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2724 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2725 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2726 argument in call to scm_make_vector.
2728 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2730 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2731 This macro is useful in applications.
2733 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2735 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2736 (scm_parse_path, scm_search_path): New Scheme level procedures.
2738 * load.h (scm_internal_parse_path, scm_parse_path,
2739 scm_search_path): Declared.
2741 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2743 * filesys.c (dirname, basename): New procedures.
2745 * init.c (scm_boot_guile_1): Removed condition around
2748 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2749 new data type (guards) for representation of C level guards and
2750 data on the wind chain.
2751 (scm_internal_dynamic_wind): New function.
2753 * dynwind.h: Declare scm_internal_dynamic_wind.
2755 * root.h (scm_root_state): Added scm_cur_loadp.
2757 * root.c (mark_root): Added comment about cur_loadp.
2759 * load.c: #include "dynwind.h";
2760 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2763 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2765 * ports.c (current-load-port): New procedure.
2767 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2769 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2770 not a tty, return #f.
2772 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2773 to Julian Satchell and Roland Kaufmann.)
2775 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2776 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2778 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2780 * debug.h, debug.c (scm_start_stack): New function. Implements
2781 the guts of old scm_m_start_stack.
2783 * debug.c (scm_m_start_stack): Use scm_start_stack.
2785 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2786 start_stack and restart_stack. (These have static scope.)
2788 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2790 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2791 readline functions to come in release 2.3. (Thanks to Chet
2793 (handle_errors): Use the above functions.
2795 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2797 * readline.c: Improvements for readline support: Handle errors
2798 better; Implement before-read-hook.
2800 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2802 * init.c (scm_boot_guile_1), readline.c: Test for
2803 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2804 assure that we have version >= 2.1.)
2806 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2808 * readline.c (scm_readline): Defer interrupts while we're calling
2811 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2812 away the string to add_history.
2813 (completion_function): Do completion for readline. (Thanks to
2815 (scm_filename_completion_function): New procedure: Filename
2817 (current_input_getc): New function. Use this one instead of
2818 standard getc from readline.
2820 * throw.c, throw.h (scm_handle_by_throw): New function: This
2821 handler throws errors to next handler on the dynwind chain.
2823 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2825 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2828 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2830 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2832 (scm_procedure_properties): Modified to return arity together with
2834 (scm_procedure_property): Added the read-only property `arity'.
2835 (scm_set_procedure_property_x): It is an error to set the `arity'
2838 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2839 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2841 * procprop.h (scm_sym_arity): New symbol.
2843 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2844 to set the dispatch procedure of an operator or entity object.
2846 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2847 Made procedure slots read-only.
2849 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2850 scm_tcs_cons_gloc case in zero args switch; Fixed args
2851 construction for operators in scm_tcs_cons_gloc case in two args
2854 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2856 * fluids.c: Removed use of assert.h (in order to avoid
2859 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2861 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2863 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2864 change makes the evaluator safer at the cost of evaluation speed.
2865 It handles the case when the user has added a non-immediate
2866 improper end of the application form, e.g., `(+ 0 . x)'.
2867 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2868 minimize the extra cost as much as possible. The new code is
2869 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2870 problem with structs planted directly in the code (e.g. by a
2871 macro). This no longer causes segmentation fault. (Thanks to
2874 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2875 arg `proc' in order to be able to throw errors; New argument
2878 * Removed extra #include "debug.h"
2880 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2882 * scmsigs.c: Declare usleep as returning void on some systems.
2883 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2886 * coop.c (usleep): Return void on some systems.
2888 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2890 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2892 * coop.c: Changed return type of usleep to int.
2894 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2895 isn't found in the OS.
2897 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2898 isn't enabled. (Thought that I had made this change ages ago...)
2900 * iselect.c: Declare bzero if not defined by OS.
2902 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2904 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2905 condition. (Thanks to John Tobey.)
2907 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2908 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2911 * __scm.h: Start the long-term project of moving to POSIX threads.
2912 Phase 1: Classification of all critical sections.
2913 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2914 for A sections. (See comments in __scm.h for details.)
2916 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2917 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2919 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2921 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2922 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2923 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2924 dependencies on $(srcdir)/Makefile.in
2925 $(top_builddir)/config.status in order to avoid circularity.
2927 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2928 from argc if argc was 0 initially.
2930 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2931 in generation of libpath.h.
2933 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2935 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2936 libguile from 2 to 3.
2938 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2940 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2942 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2944 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2945 scm_set_port_column_x, scm_port_filename,
2946 scm_set_port_filename_x): Removed optional arguments. Added
2947 proper argument checking.
2949 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2950 stack size in machine words.
2952 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2953 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2954 to Ole Myren Röhne.)
2956 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2958 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2959 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2961 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2964 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2965 procedure apply: Copy argument lists before pushing them unto the
2966 environment so that the environment won't get mutated due to
2967 manipulation of procedure arguments. This should perhaps be
2968 regarded as a temporary solution until someone finds a more
2969 efficient one. (Thanks to Maciej Stachowiak.)
2971 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2973 * script.c (scm_compile_shell_switches): Use "guile" as default
2974 zero arg if argc is NULL.
2976 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2978 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2979 is zero. (Thanks to Dirk Herrmann.)
2981 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2983 * ports.c (scm_add_to_port_table): First line is now line 0
2984 (was 1). (Interface changed according to suggestion by Per
2987 * backtrace.c (display_header): Add 1 to line and column numbers
2988 when presenting them to the user.
2990 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
2991 from debug.c --> eval.c
2993 * eval.h, eval.c (scm_eval_options_interface): New options
2995 (SCM_EVAL_STACK): New option: Size of newly created stacks,
2996 i.e. stacks for new threads.
2998 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3000 * eval.c (unsafe_setjmp): Removed with #if 0.
3002 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3005 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3006 to avoid compiler warnings.
3008 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3010 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3012 * throw.c (handler_message): Print message on current error port
3013 instead of default error port. (Thanks to Maciej Stachowiak.)
3015 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3017 * ports.c (scm_add_to_port_table): allocate in units of
3018 struct scm_port_table *, not struct scm_port_table.
3019 * posix.c (scm_close_pipe): remove the port from the port table
3021 Thanks to Rob Engle for both fixes.
3023 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3025 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3026 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3028 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3030 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3032 * backtrace.c (display_error_body, display_backtrace_body),

3035 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3036 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body

3040 don't receive the jmpbuf arg anylonger.
3041 (scm_catch): Don't accept a #f tag.
3042 (scm_throw): Check that key is a symbol.
3043 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.

3047 * async.c (async_pending): Removed declaration.
3049 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3051 * dynwind.c (scm_wind_chain): New debug function.
3053 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3054 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3055 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3056 extra layer of functions around the body and handler of a thread.
3057 This extra layer makes sure that the handler is called in the
3058 dynamic context of the surround (= empty dynwind list), but under
3059 the *dynamic root* of the body. We can not use the dynamic root
3060 of the surround since that root belongs to another thread => stack
3061 is not handled correctly. It may seem ugly to use this extra
3062 layer, but the extra cost in terms of execution time is really
3063 negligible compared to the total amount of time required to create
3064 a thread, and it would reduce maintainability to duplicate the
3065 crucial and complicated steps performed by cwdr.
3067 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3068 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3069 get re-enabled. The important effect of this is that interrupts
3070 are blocked during thread switching so that thread data structures
3071 don't risk getting messed up by an unfortunate signal.
3072 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3073 seems to do more aggressive optimization which actually move
3074 instructions around in these macros in a fatal way. Therefore:
3075 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3076 just superstitious...)
3077 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3078 This macro should be used instead of SCM_ASYNC_TICK since the
3079 latter doesn't do context switches any more.
3081 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3082 instead of SCM_ASYNC_TICK.
3084 * coop.c, iselect.c: Since thread switches are now performed with
3085 interrupts masked, we can't use the old mechanism of delivering
3086 signals immediately when they arrive. Signals must instead be
3087 delivered when the asyncs run *after* the end of the critical
3088 section in scm_internal_select. But this also means after context
3089 switch so that the signal will be delivered to a different thread.
3090 To avoid this, I have changed the protocol of
3091 coop_wait_for_runnable_thread and friends so that they are allowed
3092 to return the original thread. So, if a signal arrives during
3093 scm_internal_select, we won't any longer be forced do a context
3094 switch, but can remain in the same thread and deliver the signal
3097 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3098 scm_asyncs_pending and made it global.
3100 * iselect.c: Small fixes.
3102 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3103 coop_condition_variable_init, coop_condition_variable_wait,
3104 coop_condition_variable_signal): Changed return type from `void'
3105 to `int'. This is to adhere closer to the pthreads interface.
3106 This, in turn, is part of an attempt to provide C versions of the
3107 mutex and condition variable primitives which can be part of a
3108 frontend to COOP or pthreads.
3110 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3111 coop_condition_variable_destroy): New functions.
3113 * coop-threads.c (scm_wait_condition_variable): Use
3114 coop_condition_variable_wait_mutex.
3116 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3117 Definitions moved to coop-defs.h.
3119 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3120 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3121 scm_cond_destroy): New C interface to mutecis and cond vars.
3123 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3125 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3127 * iselect.c: Now several threads can wait on the same file
3128 descriptor. The behaviour is compatible with OS select: All
3129 threads waiting for the fd return with the same status.
3131 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3133 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3134 Can spawn a thread from application C code.
3136 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3138 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3139 gh_doubles2scm): New functions.
3141 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3143 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3144 commented-out version of gh_eval_str()
3146 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3148 * socket.c (scm_bind): free soka after use.
3150 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3152 * stime.c (tzvar): new variable.
3153 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3154 avoid memory leaks when allocating.
3156 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3158 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3161 * gc.c, tags.h: Doc fixes.
3163 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3165 * eval.c (macro-eval!): Removed. This function was a design bug.
3166 It allowed memoized code to leak out to the scheme level. Most
3167 things that you could do with `macro-eval!' can be done with
3170 1997-12-20 Tim Pierce <twp@skepsis.com>
3172 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3173 scm_fgets now depends on ftell(3) to know how many bytes were
3176 1997-12-15 Tim Pierce <twp@skepsis.com>
3178 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3179 dealing with strings.
3181 1997-12-13 Tim Pierce <twp@skepsis.com>
3183 Make %read-line more suitable for implementing read-line efficiently.
3184 * ioext.c (scm_read_line): Strip the terminating newline from a
3185 string, and return a cons of the string and its terminator.
3187 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3188 of the string that is read is stored in this memory location.
3189 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3190 * genio.c, genio.h (scm_do_read_line): Update caller.
3191 * ports.h (scm_ptobfuns): Update typedef.
3192 * fports.c (scm_fptob, scm_pipob): Update struct.
3194 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3196 * filesys.c (set_element): Return file descriptor.
3197 (fill_select_type): Return the highest file descriptor.
3198 (scm_select): Tell select about the highest file descriptor. On
3199 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3200 Therefore the extra overhead for calculating the maximum fd seems
3201 to be more than compensated. Is this correct? In any case,
3202 scm_internal_select will be much faster with this info.
3203 (scm_select, fill_select_type, set_element): Don't accept any kind
3204 of object in the file descriptor list or vector.
3206 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3208 * iselect.c (finalize_fd_sets): Bugfix.
3210 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3212 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3213 when using scm_internal_select (since we might switch to another
3216 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3218 * simpos.c (scm_system): always define: use sysmissing if not
3219 available. Check for HAVE_SYSTEM instead of _Windows (does
3220 Windows lack system or does it have an unusable one?).
3221 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3222 Let the argument be optional: if not supplied, call system(NULL).
3224 * ports.c (scm_close_port): relax the type check from OPPORTP to
3225 PORTP; closing a closed port is allowed.
3227 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3229 * fports.c (scm_fgets): Return if the last char in a chunk is
3230 newline. When fgets returns a string whose length is `size-1', it
3231 is ambiguous whether a whole line was retrieved, so we must check
3232 explicitly whether a line terminator is present.
3234 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3236 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3237 before taking the CDR. (Thanks to Harald Meland.)
3239 * filesys.c (scm_stat): Slightly optimized.
3241 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3243 * ports.c (scm_close_port): Make sure the port is open before
3246 * guile-snarf.in: Pass args through to gcc in a way that preserves
3247 whitespace boundaries. (Thanks to Greg Badros.)
3249 1997-12-02 Tim Pierce <twp@skepsis.com>
3251 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3252 statement. (Thanks to Doug Evans for pointing this out.)
3254 1997-12-01 Tim Pierce <twp@skepsis.com>
3256 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3258 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3260 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3261 errno macro expansion of this field name. (errno is a C
3262 preprocessor macro on some systems.)
3264 1997-11-29 Tim Pierce <twp@skepsis.com>
3266 * iselect.c: Doc fix.
3268 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3270 * init.c (scm_start_stack): Removed initialization of
3271 scm_the_last_stack_var.
3273 * backtrace.h: Declare scm_the_last_stack_var.
3275 * backtrace.c: Define scm_the_last_stack_var.
3277 * root.c (mark_root): Don't mark the_last_stack_var.
3279 * root.h (scm_root_state): Removed the_last_stack_var.
3281 * throw.c: Added #include "fluids.h"
3282 (ss_handler): `the-last-stack' is now a fluid.
3284 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3285 --> the_last_stack_fluid.
3287 * backtrace.c: Added #include "fluids.h"
3288 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3289 (scm_backtrace): `the-last-stack' is now a fluid.
3291 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3292 after scm_init_fluids.
3294 1997-11-28 Tim Pierce <twp@skepsis.com>
3296 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3298 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3299 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3301 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3303 * iselect.c (coop_next_runnable_thread,
3304 coop_wait_for_runnable_thread): Disable interrupts so that no
3305 async is executed before a potential error_revive.
3306 (scm_internal_select): Disable interrupts during the parts of the
3307 code which manipulate the sleep queue and the file descriptors.
3309 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3311 * Makefile.am: Added iselect.c and iselect.h.
3313 * coop.c (coop_qinit): Initialize fields used by
3314 scm_internal_select.
3315 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3316 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3317 replacement in iselect.c.
3318 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3319 coop_join): If GUILE_ISELECT enabled, use
3320 coop_wait_for_runnable_thread instead of
3321 coop_next_runnable_thread.
3322 (usleep, sleep): New replacements for system functions if
3323 GUILE_ISELECT is enabled.
3325 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3327 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3329 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3330 iselect.h. Implement Scheme level `select' using
3331 scm_internal_select. (See NEWS.)
3333 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3335 * init.c: Call scm_init_iselect.
3337 * iselect.h, iselect.c: New files. Implements
3338 scm_internal_select. (See NEWS.)
3340 1997-11-27 Tim Pierce <twp@skepsis.com>
3342 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3343 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3344 and scm_must_free, since ultimately the string returned will be copied
3345 by scm_makfrom0str anyway. Also, read any characters that may have
3346 been pushed onto the port with scm_ungetc.
3347 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3348 * ioext.c (scm_read_line): Free string after Guilifying it.
3349 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3351 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3353 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3355 * gh.h: Safely wrap prototypes for c++ usage.
3357 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3359 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3360 gh_repl (argc, argv).
3362 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3364 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3365 and to invoke scm_shell().
3366 (gh_launch_pad): took out the loading of boot-9.scm from here,
3367 since it is probably best to let the user control that. In fact,
3368 gh_repl() now invokes scm_shell() which does that.
3370 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3372 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3375 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3377 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3378 yesterday's underscore patch. (Thanks to Marius Vollmer for
3381 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3383 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3384 DLSYM_ADDS_USCORE is not defined.
3386 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3388 * gh_data.c (gh_uniform_vector_length):
3389 (gh_uniform_vector_ref): started implementing the uniform types in
3392 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3394 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3395 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3397 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3399 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3400 configure.in was changed).
3402 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3404 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3405 * Makefile.in: Regenerated.
3407 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3409 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3410 OPORT is an `open' port, not an output port.
3412 * filesys.c (scm_close, set_element, get_element, scm_chown,
3413 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3414 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3415 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3416 scm_close_port, scm_port_line, scm_set_port_line_x,
3417 scm_port_column, scm_set_port_column_x, scm_port_filename,
3418 scm_set_port_filename_x, scm_port_mode,
3419 scm_close_all_ports_except, scm_set_current_output_port,
3420 scm_set_current_error_port): Likewise
3421 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3422 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3424 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3425 * backtrace.c (display_backtrace_body): Likewise
3426 * fports (scm_setvbuf): Likewise
3427 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3428 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3429 scm_getpeername, scm_send, scm_sendto): Likewise
3430 * unif.c (scm_uniform_array_write): Likewise
3432 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3434 Minor problems with substring-related tag changes.
3435 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3436 exactly what we want to leave in to detect substrings.
3437 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3438 * tags.h: Fix diagrams and comments describing the S tag bit;
3439 remove vestigial remarks about the D tag bit.
3440 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3441 * strings.c: Formatting tweaks.
3443 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3444 variable first; then SCHEME_LOAD_PATH, with a warning message.
3445 (scm_parse_path): New function.
3446 * script.c: Doc fixes.
3448 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3450 Readline support, from Daniel Risacher.
3451 * readline.c, readline.h: New files.
3452 * init.c: #include "readline.h".
3453 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3454 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3455 * Makefile.in: Regenerated.
3456 * scmconfig.h.in: Regenerated, after change to ../configure.
3458 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3460 * gh.h: gh_vector_set -> gh_vector_set_x
3462 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3464 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3465 with the ! -> _x mapping when going from Scheme to C.
3467 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3469 * gh.h (gh_reverse):
3477 (gh_assoc): added these gh_ functions implemented as macros.
3479 * gh_predicates.c (gh_null_p):
3480 (gh_string_equal_p): added these two missing predicates.
3482 * gh_list.c (gh_append):
3487 (gh_set_cdr_x): added these routines as I go through and try to
3488 complete the picture R4RS functions that should be mirrored in the
3491 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3493 * tags.h (scm_tc7_substring): Changed the comment and code to
3494 conform with the changes below. Folks! We have suddenly two new
3495 free tc7 codes!!! Jummy, jummy!
3497 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3499 * Makefile.in: Rebuilt.
3500 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3502 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3503 * unif.c (scm_vector_set_length_x): Don't handle multibyte
3505 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
3506 (scm_tag): Don't handle multibyte strings.
3507 * read.c: Don't include mbstrings.h.

3513 * gscm.c (gscm_run_scm): Don't init mbstrings module.
3514 * gc.c (scm_gc_mark): Don't handle mbstrings.
3515 (scm_gc_sweep): Likewise.
3516 * eval.c (SCM_CEVAL): Don't handle mbstrings.
3517 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
3518 * tags.h (SCM_TYP7SD): Removed.
3519 (SCM_TYP7D): Removed.
3520 (scm_tc7_mb_string): Removed.
3521 (scm_tc7_mb_substring): Removed.
3522 * print.c (scm_iprin1): Handle char printing directly. Don't
3524 Don't include "mbstrings.h".
3525 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3526 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3528 Don't include "mbstrings.h".
3529 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3530 (SCM_SYMBOL_SLOTS): Define as 4.
3531 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
3532 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,

3537 * ports.c (scm_add_to_port_table): Don't set port's
3539 * ports.h (scm_port_representation_type): Removed.
3540 (scm_string_representation_type): Removed.
3541 (struct scm_port_table ): Removed representation field.
3542 (SCM_PORT_REPRESENTATION): Removed.
3543 (SCM_SET_PORT_REPRESENTATION): Removed.
3544 * genio.h: Use new function names.
3545 * genio.c: Don't include "extchrs.h".
3546 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
3548 (scm_putc, scm_puts, scm_lfwrite): No longer static.
3549 (scm_getc): No longer static; handle line and column changes.
3550 (scm_ungetc): Renamed from scm_gen_ungetc.
3551 (scm_do_read_line): Renamed from scm_gen_read_line.
3552 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3553 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3555 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3557 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3559 * gh_test_c.c (c_vector_test): some improvements on the vector
3562 * gh.h (gh_vector): this used to exist but do the wrong thing.
3563 Now it (almost) does the right thing, though it takes a list
3564 instead of the individual arguments. I need to see how it could
3566 (gh_list_to_vector): added this function as a macro. Corresponds
3567 to Scheme's (list->vector ...).
3568 (gh_vector_to_list): added this function as a macro. Corresponds
3569 to Scheme's (vector->list ...).
3571 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3572 gh_vector_ref, so that it resembles the Scheme routines more.
3573 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3574 resembles the Scheme routines more.
3575 (gh_make_vector): this used to be (stupidly) called gh_vector().
3576 This is the right name, since it does the same thing as the Scheme
3577 (make-vector ...) procedure.
3579 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3581 * ports.h: #include "libguile/print.h"
3583 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3584 Some indentation fixes.
3586 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3587 longer a user field; New field: class_flags.
3589 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3591 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3593 * gh_data.c (gh_bool2scm): new function which replaces
3594 gh_int2scmb(), which is now tagged as obsolete.
3596 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3598 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3599 macros should by convention not test for NIMPness.)
3600 (SCM_COERCE_OPORT): Adjust indentation.
3602 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3603 SCM_NIMP test before SCM_PRINT_STATE_P.
3605 * struct.c, struct.h, gc.c: Renamed:
3606 scm_struct_i_layout --> scm_vtable_index_layout
3607 scm_struct_i_vcell --> scm_vtable_index_vcell
3608 scm_struct_i_vtable --> scm_vtable_index_vtable
3609 scm_struct_i_printer --> scm_vtable_index_printer
3610 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3612 * struct.c (scm_print_struct): Use new printer slot; Default
3613 printing: Also output hex code of vtable so that type identity
3614 will be indicated as well.
3615 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3616 Removed struct_printer_var; Removed struct-vtable-offset;
3617 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3618 vtable-offset-user): New constants.
3620 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3621 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3622 If this slot contains a procedure, use that to print structures of
3623 the type represented by this vtable.
3625 * print.c (scm_iprin1): Don't print arguments of macro
3626 transformers. (They are always: exp env.); Bugfix: Unmemoize
3627 transformer source with correct environment.
3629 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3631 Streamlining of call-with-dynamic-root:
3633 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3634 there is now only one catch.
3635 (cwdr_outer_body): Removed.
3636 (cwdr_handler): New function.
3637 (scm_internal_cwdr): New function to perform the function of cwdr
3638 but take args that are more useful to C code. Also, the handler
3639 is now invoked *outside* of the new dynamic root, like the docs
3640 say. We no longer have to catch absolutely all errors, the caller
3641 is responsible for using a handler that does not throw, if he
3643 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3644 * root.h (scm_internal_cwdr): New prototype.
3646 Even more but risky streamlining:
3648 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3649 allocation of the jumpbuf of a root continuation. The changes
3650 below are controlled by it. They are now deactivated.
3651 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3652 the JMPBUF of the scm_rootcont to NULL before returning.
3654 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3655 when they are non-NULL.
3656 (scm_gc_mark): Likewise, mark only when non-NULL.
3658 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3659 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3661 * gc.c (scm_done_malloc): New function.
3662 gc.h (scm_done_malloc): New prototype.
3664 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3665 (struct scm_print_state) [revealed]: New field.
3666 (scm_print_state_vtable): Make visible to the outside world for
3667 type checking purposes.
3668 (scm_valid_oport_value_p): New prototype.
3670 * print.c (scm_valid_oport_value_p): New function to check whether
3671 a certain value is acceptable as a port argument.
3672 (scm_print_state_vtable): New variable.
3673 (scm_free_print_state): Set `revealed' field to false.
3674 (scm_iprin1): Call user supplied closure printer with
3675 scm_printer_apply. Print in the traditional way when there isn't
3676 one or when it returns #f.
3677 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3678 Accept a port/print-state pair in addition to just a port.
3679 (scm_prin1): Don't return the print_state to the pool when it has
3681 (scm_printer_apply): Set `revealed' field of print_state to true.
3682 (scm_init_print): Set scm_print_state_vtable.
3683 (print_state_fluid, print_state_fluid_num): Removed.
3685 * throw.h (scm_handle_by_proc_catching_all): New prototype
3686 throw.c (scm_handle_by_proc_catching_all): New function
3688 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3690 * Makefile.in: Regenerated with automake 1.2c.
3692 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3694 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3695 was looping endlessly.
3697 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3699 * strports.c (scm_eval_string): Don't close the port.
3701 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3702 former returns a nice normal integer. (Thanks to Daniel
3705 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3707 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3708 makefile variable as a build parameter called LIBS. The
3709 build-guile program will use this, for the time being.
3710 * Makefile.in: Regenerated.
3712 Thanks to Shiro Kawai:
3713 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3714 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3717 * Makefile.in: Regenerated with automake 1.2a.
3719 * script.c (scm_compile_shell_switches): If we hit the -c or --
3720 arguments, don't set the car of (command-line) to scm_usage_name,
3721 the prettified name of the guile executable; give it the full
3722 path, the way shells usually handle $0.
3724 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3726 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3727 Scheme-level name `array-map' and renamed `serial-array-map' to
3728 `serial-array-map!'.
3730 * backtrace.c: Introduced exception handlers which now enclose
3731 `display-error' and `display-backtrace' so that error reporting
3732 won't get into infinite loops if an error occurs during displaying
3733 of the error. This can very easily happen with user supplied
3734 print call-back routines.
3736 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3738 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3739 the names `serial-array-map' and `array-map' should be removed.)
3741 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3743 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3744 Added #include "objects.h"
3746 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3747 Add #include "feature.h".
3749 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3750 (modinclude_HEADERS): Added objects.h.
3752 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3753 This test is needed at many places in the code and should be
3754 abstracted. (Motivated by the need of this test in libguiletk.)
3756 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3757 (scm_eval_string), load.c (scm_primitive_load,
3758 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3759 Use SCM_EOF_OBJECT_P.
3761 * eval.c (scm_init_eval): Add feature `delay'.
3763 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3765 * scmhob.h: Removed.
3767 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3769 * list.h (SCM_LISTn): New macros. Make list creation in C code
3770 prettier. The idea comes from STk.
3772 * sequences.h, sequences.c, append.h, append.c: Removed. These
3773 files implemented non-R4RS operations which would encourage
3774 non-portable programming style and less easy-to-read code.
3776 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3779 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3780 sequences.h, #include append.h.
3782 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3785 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3787 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3789 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3791 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3793 * eval.c: Added #include "objects.h"
3795 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3798 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3799 adjacent smob numbers.
3801 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3803 * procprop.h: Added declaration of scm_i_inner_name.
3805 * gsubr.c: New global symbol scm_i_inner_name.
3807 * debug.c (scm_procedure_name): Try procedure property
3808 `inner-name' if `name' fails.
3810 * print.c (scm_iprin1): Use scm_macro_name.
3812 * eval.c (scm_m_define): Give names to macros as well; Only the
3813 first top-level definition gives a procedure/macro a name.
3814 Otherwise confusing names can turn up in backtraces.
3815 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3816 `name'; Give names to macros as well.
3818 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3819 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3822 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3824 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3826 (prinmacro): Removed. The code has been moved/merged into print.c
3827 in order to decrease code redundancy. We want macros to print in
3828 a way equivalent to procedures, and it would be silly to duplicate
3829 the required code. (We don't want to maintain two places.)
3830 (macrosmob): Print field is now a NULL pointer.
3832 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3833 scm_macro_transformer): New prototypes.
3834 (scm_tc16_macro): Declared.
3836 * print.c (scm_iprin1): Added code for printing of macros. Macros
3837 are now printed in a way equivalent to procedures.
3839 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3841 * procs.h (scm_closure_p): Added declaration.
3843 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3845 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3846 Shouldn't pass "heap" as the subr name.
3848 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3850 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3851 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3852 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3853 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3854 SCM_BOOL_T. Any non-false value is true.
3856 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3858 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3859 scm_gensym): Added prototypes.
3861 * symbols.c (scm_gensym): New function. This will speed up
3862 certain types of applications (such as macro systems) which
3863 generate lots of symbols.
3865 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3867 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
3869 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
3871 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3872 specifier, since (2) or (2 . 3) would cause SEGV.
3873 (scm_transpose_array): more argument checking fixes.
3875 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
3877 * Makefile.in: Regenerated.
3879 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3881 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3883 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3885 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3887 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3889 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3890 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3893 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3894 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
3895 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
3896 scm_array_p, scm_array_rank, scm_array_dimensions,
3897 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
3898 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
3899 scm_array_prototype): Added case scm_tc7_wvect.
3901 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3903 * errno.h: prototype for scm_strerror.
3904 * error.c (scm_strerror): new procedure.
3906 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3908 * list.c (scm_list_append_x): Allow non-pair as last argument.
3909 This is consistent with the R4RS append and is probably the
3910 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3912 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3914 * stime.h: prototype for scm_times.
3915 * stime.c (scm_times): new procedure.
3916 * ioext.c (scm_fseek): if the first argument is a file descriptor
3918 (scm_ftell): if the first argument is a file descriptor call lseek
3920 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
3921 * filesys.c (scm_chmod): if the first argument is a file descriptor,
3923 (scm_chown): if the first argument is a port or file descriptor,
3925 (scm_truncate_file): new procedure.
3926 Add DEFER/ALLOW INTS to a few other procedures.
3927 (scm_fsync): new procedure.
3928 (scm_open_fdes): new procedure.
3929 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3931 (scm_fcntl): the first argument can now be a file descriptor. The
3932 third argument is now optional.
3934 * posix.c (scm_execl, scm_execlp): make the filename argument
3935 compulsory, since omitting it causes SEGV.
3936 (scm_sync): return unspecified instead of #f.
3937 (scm_execle): new procedure.
3938 (environ_list_to_c): new procedure.
3939 (scm_environ): use environ_list_to_c. disable interrupts.
3940 (scm_convert_exec_args): take pos and subr arguments and
3941 improve error checking.
3943 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3945 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3946 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3947 argument to SCM_ASSERT. Furthermore, the name of the function
3948 should be passed as first argument when signalling
3949 SCM_WNA. (Thanks to Thomas Morgan)
3951 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3952 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3953 dispatches on the number of actual args has a default case
3954 reporting an internal error. This is a vestige from a version
3955 that mallocated a SCM vector to hold the arguments. In the
3956 current version this check is too late: if it ever happens we will
3957 have already overstepped the bounds of the array.
3959 Also, the patch [...] adds a check for too many actual arguments."
3961 mdj: Removed check for "internal programming error".
3963 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3965 * gh_io.c (gh_write): New function.
3967 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3968 throw.c (scm_internal_stack_catch): New sibling to the other catch
3969 functions. Code moved from gh_eval.c.
3970 throw.h: Added header.
3971 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
3972 scm_internal_stack_catch.
3974 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3976 * ioext.h: fix up prototypes.
3977 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3978 Scheme name is now dup->fdes.
3979 (scm_dup_to_fdes): make the second argument optional and
3980 fold in the functionality of scm_primitive_dup.
3981 (scm_primitive_dup): deleted.
3983 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3985 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
3986 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
3987 ultrix are defined. Use setvbuf instead of setbuf.
3988 (scm_setvbuf): new procedure.
3989 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
3990 (scm_setfileno): moved from ioext.c.
3991 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
3992 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
3994 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
3996 * fluids.c (scm_fluid_p): New function.
3997 * fluids.h (scm_fluid_p): New prototype.
3999 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
4001 * print.c (scm_iprin1): Enter printed structures into the print
4002 state as nested data while they are printed.

4004 (scm_init_print): Initialize them.
4005 (scm_iprin): If print_state_fluid carries a print_state, use that
4006 instead of creating a new one.
4007 (scm_printer_apply, apply_stub, struct apply_data): New
4008 definitions to help with calling printer functions written in
4010 * print.h (scm_printer_apply): New prototype.

4023 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4024 SCM_ASSERT: arg comes before pos.
4026 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4028 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4029 to a list of length zero correctly.

4047 * ioext.h: removed scm_duplicate_port prototype.
4049 * ioext.c (scm_primitive_dup2): return the new file descriptor
4050 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4052 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4053 stream has been set.
4054 (scm_duplicate_port): deleted, there's now an implementation in
4056 (scm_primitive_dup2): do nothing if newfd == oldfd.
4058 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4060 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4069 * ports.h: prototypes too.
4070 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4072 * fports.h: prototype too.
4073 * fports.c (scm_evict_ports): moved from ioext.c.
4075 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4077 * ports.c (scm_close_port): return a boolean instead of unspecified.
4078 throw an error if an error other than EBADF occurs.
4080 * filesys.h: scm_close prototype.
4081 * filesys.c (scm_close): new procedure, can close file descriptors
4082 and ports (scsh compatible).
4084 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4087 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4089 * fluids.c, fluid.h: New files.
4090 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".

4101 unique for the new root when it has a parent.
4103 * smob.h: Include "libguile/print.h" to make scm_print_state
4106 * dynl.c (free_dynl_obj): New function to free the dynamic object
4107 data. (dynl_smob): Use it.
4108 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4109 the dynamic object data below the linking of the object to avoid
4110 memory leak when the linking code throws an error. Now the code
4111 leaks a whole dynamically linked library when must_malloc throws,
4112 but that should be much less likely.
4114 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4116 Changes to compile under gnu-win32, from Marcus Daniels:
4117 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4118 (scm_localtime): Change SCM_EOF to SCM_EOL.
4119 (scm_mktime): Likewise.

4121 us Unix domain sockets are available.

4123 (scm_addr_vector): Likewise.
4124 (scm_init_addr_buffer): Likewise.

4128 * scmsigs.c (scm_pause): Don't include unless pause was found
4130 * posix.c (scm_getgroups): Don't include unless support function
4131 was found during autoconf (in this case, getgroups).
4132 (scm_setpwent): For setpwent.
4133 (scm_setegid): For setegid.
4134 * net_db.c (scm_inet_netof): Don't include unless support
4135 function was found during autoconf (in this case, inet_netof).
4136 (scm_lnaof): For inet_lnaof.

4150 scm_misc_error, not SCM_EOF.
4152 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4153 arguments for formatting the error message, not SCM_BOOL_F. I
4154 think this is left over from the (eq? '() #f) days.
4156 * read.c (recsexpr): Give this a dummy definition if
4157 DEBUG_EXTENSIONS isn't #defined.
4159 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4161 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4171 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4172 alloca.lo will be included in @LIBLOBJS@. Something better than
4173 this should be possible.
4174 * Makefile.in: Regenerated.
4176 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4178 * simpos.h: prototype for scm_primitive_exit.
4179 * simpos.c (scm_primitive_exit): new procedure, terminates the
4180 process without unwinding the stack.
4182 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4184 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4185 argument and logior its components together, so the user doesn't
4186 have to do this explicitly. Also, if regexp/basic is supplied, then
4187 turn off REG_EXTENDED.
4188 (scm_init_regex_posix): New regexp/basic symbol.
4189 (REG_BASIC): #define this if it is not already present.
4191 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4205 * Makefile.in: Regenerated.
4207 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4208 flag; I don't think we support it.
4209 (scm_make_regexp): Make sure the user doesn't pass the
4212 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4214 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4215 name them according to the SCSH convention: regexp/mumble.
4217 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.

4222 Makefile directory variables. Print a message, but don't print
4224 (versiondat.h): Print a message, but don't print all the commands.
4225 * load.c: #include "alist.h".
4226 (init_build_info): New function.
4227 (scm_init_load): Call it.
4228 * Makefile.in: Regenerated.
4230 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4232 * root.c: Establish a reliable catch-all handler for the new root.
4233 After all the Scheme handler function might signal an error too,
4234 and we don't want to lose that.
4235 (cwdr_inner_body): Renamed from cwdr_body.
4236 (cwdr_outer_body): New function, to establish the user's handler,
4237 and pass control to cwdr_inner_body.
4238 (cwdr): Establish the reliable catch-all handler here, and pass
4239 control to cwdr_outer_body.
4240 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4241 the user's handler through to cwdr_outer_body.
4242 * throw.c (scm_handle_by_message): Move guts into....
4243 (handler_message): New static function.
4244 (scm_handle_by_message_noexit): New function.
4245 * throw.h (scm_handle_by_message_noexit): New prototype.
4247 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4248 across this. Only works on GCC. Otherwise, we hope for the best.
4249 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4250 the feeling that real thread systems will not need this...
4252 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4254 Try to detect when people are using one version of libguile and a
4255 different version of ice-9. People have been skewing things and
4256 sending in bug reports.
4257 * Makefile.am (versiondat.h): New file to generate.
4258 * version.c: #include "versiondat.h", to get version info.

4262 * scmconfig.h.in, Makefile.in: Regenerated.
4263 * Makefile.in: Regenerated.
4265 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4266 primitive definitions under their Scheme names.
4268 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4269 1:2. Helps avoid confusion between installed and uninstalled libs.
4271 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4274 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4275 backslash from definition; this should be used like: GDB_INTERFACE;
4277 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4279 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4280 new port unbuffered until its stream has been set.
4282 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4284 * ports.h: new prototype.
4285 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4287 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4289 Make things compile neatly under Sun's C compiler.
4290 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4291 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4292 unsigned, because that's what the ANSI function takes.
4293 * extchrs.h (xmbtowc): Corresponding change to prototype.
4294 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4296 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4297 argument plain char *.
4298 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4300 * tag.c (scm_tag): Remove unreachable statement.
4301 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4302 top of the word, it should be unsigned.
4304 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4305 is defined, to avoid warnings; it's only used in the
4306 conflict-checking code. Which might go away anyway.
4307 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4308 conditionals; put the label definition in an #if too, to stifle
4311 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4312 ChangeLog-threads in the distribution.
4313 * Makefile.in: Regenerated.
4315 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4317 * guile-snarf.in: Changed regexp to support CPPs that insert
4318 whitespace between lexical tokens (which munges the `%%%' snarf
4321 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4323 * load.c (scm_init_load_path): Append $(datadir)/guile to
4324 %load-path, so modules do not have to be installed in Guile's
4325 current version directory.
4327 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4329 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4330 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4331 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4332 call the sysdep functions with deferred ints.
4333 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4334 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4335 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4338 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4341 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4343 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4345 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4347 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4350 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4352 * eval.c (scm_lookupcar1): New procedure to cope with a race
4353 condition during lookup (when using threads).
4354 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4355 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4358 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4360 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4361 supplied. (Change from Tim Pierce.)
4363 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4365 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4366 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4367 default and not `()'. `#f' is the canonical non-value in Scheme,
4370 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4372 * struct.c (struct_printer): New variable that holds a handle on
4373 the Scheme variable *struct-printer*. This variable can be set by
4374 Scheme code to override the printing of structures.
4375 (scm_print_struct): If struct_printer is set, call it. If it is
4376 not set, or returns #f, print the structure in the old fashion.
4377 Include "eval.h" for scm_apply.
4379 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4381 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4382 scm_struct_i_n_words to get the number of fields, not
4383 -scm_struct_n_extra_words.
4385 On the route to fancier struct printing:
4386 * struct.c (scm_print_struct): New function to print a structure.
4387 Include "genio.h" to support it. This function doesn't do
4388 anything interesting right now, but I think it should be here
4390 * struct.h: Include "print.h" and add prototype for
4392 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4393 print structures ourself.
4395 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4397 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4398 before applying the handler in case it doesn't return.
4400 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4402 * scmsigs.h, async.h: updated.
4404 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4407 * posix.c (scm_uname): interpret only negative values as an error.
4408 Solaris normally returns a positive value.
4410 * script.c (scm_compile_shell_switches): if we are not going into
4411 an interactive repl, set scm_mask_ints to zero so that asyncs can
4414 * simpos.c (scm_system): don't ignore/unignore signals around
4417 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4420 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4421 done in boot-9.scm instead.
4423 * scmsigs.c, async.c: Major rewriting of signal handling code.
4424 (scm_sigaction): new procedure.
4425 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4427 (scm_raise): return unspecified, throw error on failure.
4429 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4431 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4432 feature, to help boot-9.scm decide whether to import the regex
4435 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4437 * eval.c: Include scmconfig.h at the beginning of the file so that
4438 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4441 * regex-posix.c: #include "_scm.h" before conditionally #including
4442 <regex.h>; the former defines HAVE_REGCOMP.
4444 * regex-posix.c: #include <regex.h> conditionally, so the file is
4445 CPP'able (for dependency scanning) even on systems that don't have
4448 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4450 Add new R4RS-compliant syntax for keywords.
4451 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4452 regardless of the setting of the `keywords' read option.
4453 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4454 can be re-read no matter what the setting of the `keywords' read
4457 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4459 Add support for POSIX regular expressions.
4461 * regex-posix.c, regex-posix.h: New files. (Some code
4462 is taken liberally from rx/rgx.c in the old Guile dist.)
4464 * init.c: Include regex-posix.h.
4465 (scm_boot_guile_1): Call scm_init_regex_posix.
4467 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4468 Add regex-posix.[ch] sources.
4469 * Makefile.in: Regenerated.
4471 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4472 to do this automatically? It didn't for me, bleh.)
4474 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4476 * fports.c (print_pipe_port): New function.
4477 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4478 latter doesn't even take the right arguments.
4480 * Makefile.am: Increment shared lib revision number. I think
4481 sometimes the uninstalled Guile finds the installed shared lib;
4482 Gord says doing this might help. As things turned out, I can't
4483 say whether it does.
4484 * Makefile.in: Regenerated.
4486 * gh_init.c (gh_enter): Cast c_main_prog to a void * before

4491 write_void_port, flush_void_port, getc_void_port, close_void_port,
4492 noop0): Use ANSI prototypes instead of K&R declarations, so the

4530 * script.c (scm_find_executable): Use prototype-style definition
4531 here; apparently it's not quite right to have const in a prototype
4532 and then use a K&R declaration. I wonder if stuff like this will
4533 go away if we compile with -Wrequire-prototypes, or whatever that
4534 is... (Bernard URBAN)
4536 * scmhob.h: New text from Bernard URBAN.
4538 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4540 * script.c: Don't #define const on hpux. Configure takes care of
4541 this. (Thanks to Larry Schwimmer.)
4543 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4544 decide whether to #include <unistd.h>, instead of listing a bunch
4545 of systems. Don't #include stdio twice. Removed dyked-out
4546 definition of scm_find_impl_file.
4548 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4550 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4551 library version info to 1:0.
4552 * Makefile.in: Regenerated.

4559 throw.c: Update copyright years; these files have been worked on
4560 significantly in 1997, but only had copyright years for 1996.
4561 Also, change name of copyright holder on some from Mikael
4562 Djurfeldt to Free Software Foundation; he has signed papers
4563 assigning the changes to the FSF.
4565 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4566 reason not to give the user the option.
4568 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4569 Return #f on end-of-file when scanning table (i.e. when called
4570 with no arguments). Try to catch errors, when we can.
4571 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4573 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4574 external declarations. These are useful.
4576 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4578 * posix.c: don't include <sys/select.h> or define macros for
4579 select, since they were not used in this file.
4581 * filesys.c (scm_select): make the fifth parameter microseconds,
4582 not milliseconds. let the fourth parameter be either a real value
4583 or an integer or #f. The first, second and third arguments can
4584 now be vectors: the type of the corresponding return set will be
4586 (set_element, get_element): new static procedures.
4588 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4590 * strports.c (scm_eval_string): New function.
4591 (scm_eval_0str): Trivially re-implemented in terms of
4593 * strports.h (scm_eval_string): New extern decl.
4595 * net_db.c (h_errno): Add extern decl for this.
4597 * fports.c (local_pclose): New function.
4598 (scm_pipob): Use it in the initializer here.
4601 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4602 Use a meaningful error message when signalling an error. For
4603 this, scm_gethost must check h_errno rather than errno.
4605 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4607 * Makefile.in: Regenerated, using automake-1.1p.
4609 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4611 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4612 not SCM_UNSPECIFIED.
4614 * script.c (scm_compile_shell_switches): don't append (quit) if
4616 (scm_shell): call scm_exit_status and exit on the result of the
4619 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4621 Ensure that shared substrings are handled properly when passed to
4622 a system call or other foreign function. Many thanks to Tim
4624 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4625 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4626 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4627 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4629 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4630 (scm_display_error_message): use RO macros when strings may be RO.
4631 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4632 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4633 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

4637 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4638 scm_strftime), vports.c (scm_make_soft_port): use
4639 SCM_COERCE_SUBSTR to make sure shared substrings are
4642 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4644 * error.c (scm_error): Add newline to error message.
4646 * init.c (scm_init_standard_ports): Doc fix.
4648 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4650 * dynl-shl.c: Completely replaced with new code from Bernard
4653 * script.c (scm_ice_9_already_loaded): New variable.
4654 (scm_compile_shell_switches): Use it.
4656 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4658 * filesys.c (scm_input_waiting_p): add missing third argument to
4661 * stime.c (scm_localtime): copy the result of localtime before
4662 calling gmtime in case they share a buffer.
4663 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4666 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4668 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4670 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4672 * Makefile.am (check-local): New target, which causes 'make check'
4673 to run gh_test_c and gh_test_repl, with some trivial input.
4674 * Makefile.in: Rgnrtd.
4676 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4678 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4681 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4683 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4684 sure how this was supposed to work.
4685 (scm_async_click): don't send SCM_TICK_SIGNAL.
4686 (scm_init_async): don't initialize %tick-thunk.
4688 * the following change doesn't affect the Scheme interface:
4689 gc-thunk is called at the end of garbage collection. however it's
4690 no longer implemented by pretending it's a signal.
4692 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4693 system async corresponding to scm_gc_thunk.
4694 * async.h: declare scm_gc_async.
4695 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4696 gc-thunk directly, instead of going through a signal handler.
4697 (scm_gc_async): new variable, points to the GC system-async.
4698 (scm_init_async): save the GC async as scm_gc_async instead
4699 of using system_signal_asyncs.
4700 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4702 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4704 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4705 Don't screw up if we're interrupted.
4706 * Makefile.in: Regeneradet.
4708 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4710 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4712 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4713 we're not using AM_INIT_GUILE_MODULE any more.
4714 * Makefile.in: Reneregated.
4716 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4718 Functions for finding variable bindings, grace à Tim Pierce.
4719 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4720 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4722 Get 'make dist' to work again.
4723 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4724 * Makefile.in: Regenerated, like a surry without a fringe on top.
4726 Changes for reduced Guile distribution: one configure script,
4728 * configure.in, configure: Removed.
4729 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4730 real configure script lives.
4731 * Makefile.in, scmconfig.h.in: Regenerated.
4733 * init.c: #include "script.h", to get prototype for script.c's
4736 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4738 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4739 scm_must_malloc, not raw malloc.
4741 * script.c (scm_compile_shell_switches): Dyke out debugging output
4744 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4746 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4748 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4749 system has them. Hope this is safe. Previously
4750 sys/timeb.h was included if HAVE_FTIME was defined or if
4751 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4752 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4754 * ioext.c (scm_setfileno): add missing third argument to
4755 scm_misc_error call.
4757 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4759 * eq.c (scm_equal_p): Correctly compare strings of different
4760 varieties. (Thanks to Tim Pierce.)
4762 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4764 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4765 #! block comment must occur on a line all by itself.
4767 Move most of the guts of shell command processing into libguile,
4768 so guile.c can be very small (and eventuallly auto-generated. (I
4769 mean, generated mechanically, not self-generated. Hmm.))
4770 * guile.c, script.c, script.h: New source files.
4771 * init.c (scm_boot_guile_1): Call scm_init_script.
4772 * libguile.h: #include "script.h".
4773 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4774 targets, for new executable.
4775 (libguile_la_SOURCES): Mention script.c.
4776 (modinclude_HEADERS): Add script.h.
4777 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4778 not dynamic linking is enabled. This is because we're generating
4779 executables now. Move CY_AC_WITH_THREADS call after those, so the
4780 values of cy_cv_threads_libs captures the libs chosen above.
4781 * Makefile.in, configure, aclocal.m4: Regenerated.
4783 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4784 We don't maintain this interface any more, and it just confuses
4787 * alloca.c: #include <scmconfig.h>, not <config.h>.
4788 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4789 it'll get included in disties.
4791 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4793 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4794 be distributed, because they confuse people.
4795 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4797 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4799 * configure.in: check for presence of gethostent (not present on
4800 OpenBSD by default).
4801 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4802 * configure, scmconfig.h.in: Regenerated.
4804 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4806 * backtrace.c (scm_backtrace): Split message string across
4807 newlines properly. GCC is more tolerant of this than other
4810 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4812 Merge threads directory into libguile.
4813 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4814 threads.h: New source files.
4815 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4816 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4818 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4819 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4820 coop-threads.c.cygnus, coop-threads.h.cygnus.
4821 * configure.in: If we're using threads, include threads.o in
4823 * _scm.h, libguile.h: threads.h lives in this directory now.
4824 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4825 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4826 currently used, but brought along for information's sake.
4827 * ChangeLog-threads: log from old 'threads' directory.
4828 * Makefile.in, configure: Rebuilt.
4830 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4832 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4835 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4837 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4839 Merge GH interface library into libguile.
4840 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4841 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4842 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4843 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4845 (EXTRA_libguile_la_SOURCES): ... here.
4846 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4847 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4848 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4849 New variables, describing how to build the gh test programs.
4850 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4851 build the test programs, and we probably should have been linking
4852 libguile.la against them all along, to support AIX shared libs.
4853 Add cflags for threads to CFLAGS; add libs for threads to new
4854 variable THREAD_LIBS, used in Makefile.am.
4855 * ChangeLog-gh: log from old `gh' subdirectory.
4856 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4858 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4860 * acconfig.h: Undo change of Apr 9; including the definition of
4861 PACKAGE in the guile headers conflicts with applications' own
4863 * scmconfig.h.in: Regenerated.
4865 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
4867 * filesys.c (scm_fcntl): New function from Roland McGrath.
4868 (scm_init_filesys): New symbols for use with fcntl.
4869 * filesys.h: Added prototype.
4871 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
4872 when PROC is receiving no arguments.
4874 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4876 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4877 have S_IFSOCK. This is the case under Ultrix.
4879 * posix.c (scm_status_exit_val, scm_status_exit_val,
4880 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4881 Ultrix versions of WIFSTOPPED, etc., which assume that their
4882 arguments are lvalues (hmm).
4884 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4886 * eval.c: Doc fixes.
4888 * throw.c: Doc fixes; rearranged.
4890 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
4892 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
4894 * acconfig.h: Added entry for PACKAGE.
4895 * scmconfig.h.in: Regenerated.
4897 Changes to work with automake-1.1n, which has better libtool support.
4898 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4899 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
4901 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
4903 * Makefile.in: Rebuild.
4905 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4907 * stime.c (scm_mktime): take an optional zone argument.
4908 (scm_localtime): check putenv return value.
4909 (scm_strftime, scm_strptime): moved from posix.c. move #include
4911 stime.h, posix.h: update prototypes.
4912 (bdtime2c, setzone, restorezone): new static procedures.
4913 (scm_mktime, scm_strftime): use them.
4914 (scm_strftime): don't call mktime before strftime. Use
4915 filltime for return value.
4916 (filltime): convert NULL zname to #f.
4917 (scm_strptime): return a count of characters consumed, not
4918 the remaining string.
4920 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4922 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
4923 (scm_mktime): likewise.
4925 Uncomment localtime and mktime.
4927 * configure.in: add AC_STRUCT_TIMEZONE.
4929 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4931 * stime.c (scm_init_stime): don't define ticks/sec.
4932 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4933 return value problem and is still portable.)
4935 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4937 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4938 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4939 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4940 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4941 cpp_err_symbols.c): Corresponding changes.
4942 * Makefile.in: Regenerated.
4944 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4946 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4947 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4948 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4949 * putenv.c: new file, from sh-utils 1.12.
4951 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4952 since allocation isn't for Scheme objects.
4953 (scm_putenv): copy strings before placing in the environment.
4955 * stime.c (scm_current_time): throw an error if time returns -1,
4956 instead of returning #f.
4957 (scm_get_internal_real_time, scm_get_internal_real_time): use
4958 scm_long2num for return value instead of SCM_MAKINUM.
4960 * stime.h: prototypes updated.
4962 * stime.c (scm_time_in_msec): apparently unused, deleted.
4964 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4966 * configure.in: check for gettimeofday.
4968 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4969 which may be more usefully portable than a gettimeofday interface.
4971 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4973 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
4975 * Makefile.in: Regenerated.
4977 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4979 * stime.c (filltime): recovered static procedure.
4980 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4983 * posix.h: add prototype for scm_close_pipe, remove prototypes for
4984 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
4986 * posix.c (scm_mknod): split the mode argument into type and perms
4987 arguments, like the extra fields returned by stat.
4989 * fports.c (scm_pipob): set the close, free and print procedures.
4990 (scm_close_pipe): new procedure.
4992 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
4993 define them in boot-9.scm
4995 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4997 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4998 wan't defined. Don't include fd.h.
5000 * Previously fd.h was regenerated whenever configure was run,
5001 forcing a couple of files to be recompiled.
5003 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5004 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5005 Check for _fileno as well as _file.
5007 * ioext.c: don't fd.h.
5008 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5011 * Change the stratigy for getting information about errno
5012 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5013 generating lists of symbols during the build process, which will
5014 not always work, include comprehensive lists in the distribution.
5015 To help keep the lists up to date, the "check_signals" and
5016 "check_errnos" make targets can be used.
5018 * configure.in: don't check for a command to extract errno codes.
5019 * Makefile.am: update file lists, remove errnos.list and errnos.c
5020 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5021 check_errnos targets.
5022 (CLEANFILES): remove errnos.c and errnos.list, add
5023 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5024 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5025 * errnos.default: deleted.
5026 * cpp_signal.c: new file.

5028 * cpp_err_symbols, cpp_sig_symbols: new files.
5029 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5030 * error.c (scm_init_error): #include cpp_err_symbols instead of
5032 * posix.c (scm_init_posix): don't intern signal symbols. #include
5035 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5037 * strop.c (scm_i_index): allow the lower bound to be equal to the
5038 length of the string, so a null string doesn't always give an error.
5040 * posix.h: new prototypes.
5041 * posix.c (scm_status_exit_val, scm_status_term_sig,
5042 scm_status_stop_sig): new functions, as in scsh. They break down
5043 process status values as returned by waitpid.
5045 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5047 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5048 configure doesn't know about it.
5050 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5052 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5054 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5055 which defines C variables with global linkage.
5057 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5059 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5062 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5064 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5065 has time to check why this doesn't work well with continuations.
5067 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5069 * Fix shell syntax error; some shells won't tolerate
5070 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5072 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5074 * posix.c (scm_uname): throw an error if uname fails instead
5077 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5079 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5082 * async.c (scm_ints_disabled): definition moved from error.c.
5084 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5086 * acconfig.h: Removed PACKAGE.
5088 * scmconfig.h.in: Regenerated.
5090 * snarf.h: g++ says it's non-portable not to specify the first
5091 argument in a varargs declaration. I introduced the first
5092 argument by using preprocessor conditionals.
5094 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5096 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5097 (scm_freopen): use RO string macros for filename and modes.
5098 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5100 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5101 (scm_mknod): use RO string macros for path.
5103 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5104 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5106 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5107 use SCM_ROSTRINGP and SCM_ROCHARS.
5109 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5111 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5114 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5115 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5116 support for byte vectors.
5118 * print.c (scm_iprin1): Limit number of vector elements printed
5119 according to pstate->length.
5121 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5123 * backtrace.c (scm_display_error_message): don't segv if message
5126 * error.h: prototype for scm_error_scm.
5128 * error.c (scm_error_scm): new procedure, reimplements scm-error
5129 in C and uses scm_error.
5131 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5133 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5134 pointer to the Scheme variable read-hash-procedures and intern it
5135 in scm_init_read. Modify scm_read_hash_extend and
5136 scm_get_hash_procedure to use the pointer.
5138 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5140 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5141 (SCM_KEYWORD_STYLE): defined.
5143 * read.c (scm_read_opts): add a keywords option. This isn't a
5144 boolean option, in case someone wants to add support for DSSSL
5146 Setup scm_keyword_prefix symbol.
5147 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5149 I've left keyword support disabled by default, since it doesn't
5150 seem to break the module system and it gives R4RS standard behaviour.
5151 It can be reactivated with (read-set! keywords 'prefix).
5153 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5155 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5156 before constructing arbiter.
5158 * eval.c (scm_m_define): Bugfix: Check that the object is a
5159 closure before setting the procedure property!
5161 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5163 * ports.c: Removed `ungetc-char-ready?'.
5165 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5167 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5168 (idea from Mikael: make it a pair so scm_permanent object only
5170 (scm_read_hash_extend): don't call scm_permanent_object.
5171 (ideas from Mikael): if chr is already in the list, replace its
5172 procedure instead of appending it again. If proc is #f, remove
5174 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5176 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5178 * gdbint.c (gdb_read): update scm_lreadr usage.
5180 * load.h: update prototypes.
5182 * load.c (scm_primitive_load, scm_read_and_eval_x,
5183 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5185 * read.h: add prototype for scm_read_hash_extend. Change args for
5188 * read.c (scm_read_hash_procedures): new variable.
5189 (scm_read_hash_extend): new procedure.
5190 (scm_get_hash_procedure): new procedure.
5191 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5192 for extended # processing.
5193 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5194 scm_read_token): remove case_i, sharp arguments. Change callers.
5196 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5198 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5199 (SCM_CASE_INSENSITIVE_P): define.
5201 * read.c: add case-insensitive option to scm_read_opts.
5202 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5203 to determine whether to convert symbol case.
5204 (default_case_i): definition removed.
5205 * read.c (scm_read_token): if case_i, downcase ic before doing
5208 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5210 * configure.in: Added configuration option `guile-debug'.
5211 Configure with --enable-guile-debug if you want a bunch of extra
5212 functions used for debugging when developing Guile.
5214 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5216 * procs.c (make-cclo): New undocumented debugging procedure: Make
5217 compiled closure with internal procedure PROC and length LENGTH.
5218 Only compiled if GUILE_DEBUG is defined.
5220 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5222 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5224 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5226 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5227 with 3 or more args internally to the evaluator.
5229 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5231 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5232 with 3 or more args internally to the evaluator. This is mainly
5233 because we don't want to pass entry and exit points of the
5234 debug support twice, but it also seems to increase the speed of
5235 the evaluator for such calls (e. g. (+ 1 2 3)).
5237 * backtrace.c (scm_display_application): New procedure:
5238 display-application; Set fancy printing parameters individually
5239 for different types of display (backtrace, error, application).
5240 (These should of course be customizable!)
5242 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5243 clear the CHECK-flags.
5245 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5247 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5249 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5251 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5252 from pairs with a GLOC in the car.
5254 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5255 otherwise `symbol-hash' will behave badly.
5256 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5257 we get segmentation fault!
5259 * symbols.c: Added #include "weaks.h". New functions:
5260 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5261 moved to an extraneous library when we split libguile.)
5263 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5265 * filesys.c (scm_stat): stat now takes fport arguments too as
5266 documented in the manual.
5268 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5270 * debug.c (scm_single_step): Bugfix: Call continuation with
5271 scm_call_continuation instead of throwing to it.
5273 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5275 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5276 argument wasn't declared to be optional.
5278 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5280 * stime.c (scm_init_stime): Add feature "current-time".
5282 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5284 * throw.h: prototype for scm_exit_status.
5285 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5286 args to derive an exit status. Allows (quit) to work from a
5288 (scm_exit_status): new function.
5291 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5293 * eval.c (scm_deval): Removed some old code.
5294 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5296 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5299 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5302 * procs.c: Introduce the existent C function scm_thunk_p at the
5303 Scheme level as well.
5305 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5307 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5308 used from C to easily lookup the value of a symbol in the current
5311 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5313 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5314 scm_init_unif in this file. This will also fix a previous problem
5317 * configure.in: Added AM_MAINTAINER_MODE
5319 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5321 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5324 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5326 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5327 source files that are not always included in libguile but should
5328 have their dependencies calculated by automake. This variable is
5329 recognized by automake, no further magic is needed.
5330 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5331 to deal exclusively with *.lo files, as it seems. The *.o files
5332 are built automatically when the corresponding *.lo file gets
5335 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5337 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5340 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5342 * unif.c (scm_array_set_x): minor change to argument error checking.
5344 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5346 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5347 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5348 They should only be included in the library at configure.in's
5350 (libguile_la_LDADD): Include the appropriate .lo files here.
5351 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5352 so we know when to build them (and their .lo bretheren).
5353 * configure.in (LIBLOBJS): New substituted variable. We let
5354 configure decide which .o files to include in LIBOBJS, and then
5355 put the corresponding list of .lo files in LIBLOBJS. The latter
5356 is what we pass to libtool.
5357 * Makefile.in, configure: regenerated.
5359 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5361 * symbols.c (scm_sysintern0): New function. Contains the core of
5362 old scm_sysintern but doesn't take a second value argument.
5363 (scm_sysintern): Now uses scm_sysintern0.
5364 (scm_sysintern_no_module_lookup): Renamed to
5365 scm_sysintern0_no_module_lookup and doesn't take a second value
5366 argument any longer.
5368 * symbols.h (scm_sysintern0: Added declaration.
5370 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5371 scm_sysintern when interning option keys. Otherwise we risk
5372 destroying the values of already interned variables.
5374 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5375 scheme-level boolean (use SCM_NFALSEP).
5377 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5379 (scm_backtrace): New function. (C version of old function from
5380 boot-9.scm) Motivation: Make it possible to display backtraces
5381 without depending on boot-9.scm. (I'm uncertain if this
5382 motivation is good enough...)
5384 * root.h (scm_root_state): Add member the_last_stack_var.
5385 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5387 * root.c (mark_root): Mark scm_the_last_stack_var.
5389 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5392 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5394 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5395 1. mark_lazy_catch didn't mark the smob.
5396 2. Both functions above have standard variants:
5397 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5398 free_lazy_catch --> scm_free0.
5400 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5402 * throw.c (scm_internal_lazy_catch): New function.
5403 (scm_lazy_catch): Rewritten to use it.
5404 (scm_ithrow): Handle the new lazy catch representation.
5405 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5406 that doesn't have a jmpbuf is a lazy catch clause.
5407 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5408 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5409 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5411 (scm_init_throw): Register the new lazy-catch smob type.
5412 * throw.h (scm_internal_lazy_catch): decl for new function.
5414 * throw.c (scm_internal_catch): Doc fixes.
5416 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5417 configure.in. Including this might cause problems if applications
5418 that link against libguile include their own copies of alloca, but
5419 if they're using autoconf, they should be adding libguile to LIBS
5420 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5421 the copy in libguile, and things will be okay. (I think.)
5423 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5425 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5427 strop.h: move prototypes too.
5429 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5431 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5434 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5435 etc. I deleted them from filesys.c long ago, but didn't
5436 notice they were here too (although ineffective since
5437 sys/stat.h wasn't included).
5439 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5441 * eval.c: Don't define alloca in GCC case. gcc will automatically
5442 use __builtin_alloca if appropriate.
5444 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5446 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5447 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5448 that values of automatic variables are preserved. See comments
5449 for safe_setjmp for details.
5451 Change from Thomas Morgan:
5452 * variable.c: Include eq.h.
5453 (var_equal): New function.
5454 (variable_smob): Use var_equal as the discriminator for variables.
5456 * throw.c (s_throw): Remove extraneous declaration.
5458 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5459 * eval.c: Add necessary CPP cruft to support that.
5460 * configure, Makefile.in, scmconfig.h.in: regenerated.
5462 Change from Thomas Morgan:
5463 * procprop.c (scm_procedure_properties): Convert the Scheme
5464 boolean returned by scm_procedure_p into a C boolean before using
5465 it as a condition for SCM_ASSERT.
5466 (scm_procedure_property): Likewise.
5468 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5469 indications of Unixness.
5472 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5474 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5476 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5478 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5479 "unknown # object" error messages.
5481 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5482 (scm_i_index) and declare it static. Add a 'direction' argument
5483 to indicate what way the search should go.
5484 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5486 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5487 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5489 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5491 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5493 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5494 to avoid clash with various scsh forks.
5496 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5498 The following two changes (ramap.c, throw.c) are motivated by the
5499 apparent unportability of forward declarations of static arrays of
5500 the form `static foo bar[];'.
5502 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5503 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5505 * throw.c (scm_throw): Moved above scm_ithrow.
5507 * options.h: Removed the extern declarations of scm_yes_sym and
5508 scm_no_sym since these are static.
5510 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5512 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5514 * Makefile.am: remove AWK=@AWK@.
5515 Add a rule for generating errnos.list.
5516 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5518 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5519 don't extract errnos, just set a variable (avoids the
5520 need to recompile error.c just because configure is run.)
5522 * unif.h: update prototypes.
5523 * unif.c (scm_uniform_array_read,write): change the offset and
5524 length arguments to start and end, for consistency.
5526 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5528 * ioext.h: update prototypes.
5529 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5530 scm_read_line_x, it's a more general procedure using an
5531 interface from scsh. read-line and read-line! are now defined
5533 Note that the new read-line trims the terminator
5534 by default, previously it was appended to the returned string. An
5535 optional argument specifies how to process the terminator (scsh
5536 compatible). For the old behaviour: (read-line port 'concat).
5537 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5538 returns a pair, but is converted to multiple values if the scsh
5541 socket.h: update prototypes.
5542 * socket.c (scm_recvfrom): for consistency with other procedures,
5543 take start and end as separate optional arguments.
5544 (scm_recv, scm_recvfrom): don't allow the second argument
5545 to be a size, only a buffer. Change the scheme names to
5546 recv! and recvfrom!. Don't return the buffer.
5548 * ioext.h, posix.h: move prototypes too.
5549 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5550 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5551 "read.h" and "unif.h".
5552 * ioext.c: include "chars.h"
5554 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5556 * dynl.c: The dynamic linking and module registration functions
5557 are now defined even when dynamic linking is not available for the
5558 host system. Some of their functionality can be done without
5559 dynamic linking; when it's really needed, they throw errors.
5561 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5563 * configure.in: Only define DYNAMIC_LINKING when one of the system
5564 dependent functions is detected.
5565 * dynl.c (scm_dynamic_func): New function to get the address of a
5566 function in a dynamic object.
5567 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5568 produced by scm_dynamic_func as the thing to call.
5570 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5572 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5573 (scm_register_module_xxx, scm_registered_modules,
5574 scm_clear_registered_modules): New functions.
5576 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5578 * symbols.c (scm_sysintern): Renamed to
5579 scm_sysintern_no_module_lookup.
5580 (scm_sysintern): New function to take the place of the old
5581 scm_sysintern. It uses the current toplevel lookup closure to give
5582 the symbol its value. This is a temporary hack to put packages
5583 like gtcltk into their own module.
5584 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5585 us whether `scm_top_level_lookup_closure_var' has been initialized
5587 * eval.c (scm_init_eval): Set it.
5589 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5591 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5592 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5594 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5596 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5597 scm_sys_dup): deleted: FD capability will be added to other
5599 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5600 scm_fd_free, fd_smob, scm_intern_fd.
5601 (scm_open): renamed from scm_sys_open. Return a port instead of
5602 an FD object. Make the mode argument optional.
5603 (scm_sys_create): deleted, it's just a special case of open.
5604 (scm_init_filesys): move interning of constants O_CREAT etc.,
5605 here (were previously using SCM_CONST_LONG macro).
5606 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5608 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5609 include "fports.h" and <stdio.h>
5610 (scm_stat, scm_select): don't support FD objects.
5612 * error.h: adjust scm_syserror_msg prototype.
5613 * error.c (scm_syserror_msg): take an extra argument for errno.
5614 Using the global value didn't always work, since it could be
5615 reset by procedure calls in the message or args arguments.
5617 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5618 I don't understand why the check was there (and what about the
5621 * strop.c (scm_string_copy): allow shared substrings to be copied.
5623 * unif.h: corresponding change to prototypes.
5624 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5625 recognize two new optional arguments: offset and length. Allow
5626 the port argument to be an integer (file descriptor, for scsh).
5627 Include <unistd.h> for "read" prototype.
5629 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5631 * socket.c: don't include filesys.h.
5633 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5635 * Makefile.am: add AWK=@AWK@ (?)
5637 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5639 Add a rule to generate errnos.c from errnos.
5640 * error.c (scm_init_error): include errnos.c.
5641 * errnos_cnvt.awk: new file, converts the list of errno codes to
5643 * errnos_get.c: new file.
5644 * errnos.default: new file, contains errnos to try if they can't
5645 be extracted from errno.h.
5646 * configure.in: if using GCC, try and extract errno codes from
5650 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5652 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5653 * Makefile.am: Made libguile into a libtool library.
5654 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5655 Set libtool_libs to indicate that libguile is a libtool library.
5656 See guile/ChangeLog for details.
5657 * .cvsignore: ignore "*.lo", the libtool library objects.
5659 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5661 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5662 use htons in getservbyport argument.
5664 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5666 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5667 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5670 * objprop.c (scm_object_property): No need to take the CDR of the
5671 value returned by scm_object_properties, since Aug 20 change.
5673 * configure.in: When checking for struct linger, #include
5674 <sys/types.h> as well as <sys/socket.h>. I've never known
5675 <sys/types.h> to cause any portability problems, and Solaris's
5676 <sys/socket.h> needs it.
5677 * configure: Rebuilt.
5679 I think the Sun compiler has chosen a perverse way to interpret
5680 ANSI declarations combined with K&R definitions. We'll
5681 appease it a little bit. But when it invades France, we fight.
5682 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5683 * print.h (scm_iprlist): Here too.
5684 * numbers.c (scm_divbigdig): Change definition to match
5685 declaration in numbers.h.
5686 * unif.c (scm_makflo): Change definition to match declaration in
5689 * init.c (scm_boot_guile): Don't return the value of
5690 scm_boot_guile_1. This function doesn't return a value;
5691 scm_boot_guile_1 doesn't return a value (or return at all).
5693 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5696 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5697 compile. I have a feeling this function is a bad idea anyway ---
5698 one should always test for features, not systems.
5700 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5701 semicolons. Only pure luck kept this from being noticed earlier.
5703 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5705 * socket.c (scm_recvfrom): Added missing semicolon.
5707 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5709 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5710 the buffer and start and end positions for scsh networking
5713 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5715 * configure.in: Revert previous change to this file; the problem
5716 is due to transient automake weirdness.
5717 * configure: Rebuilt.
5719 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5720 PLUGIN/guile.libs. configure generates the latter from the former.
5721 * Makefile.in: Rebuilt.
5723 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5724 need this if we install scripts, like guile-snarf.
5725 * configure: Rebuilt.
5727 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5729 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5731 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5733 * socket.c (scm_addr_vector): fix faulty scm_listify.
5735 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5737 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5738 style block comment is no longer considered an error.
5740 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5742 * PLUGIN/guile.libs.in: New file.
5743 * PLUGIN/guile.libs: Removed from repository.
5744 * configure.in: Create PLUGIN/guile.libs from
5745 PLUGIN/guile.libs.in. This is for including additonal libraries
5746 needed for dynamic linking.
5747 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5748 instead of PLUGIN/guile.libs.
5750 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5752 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5754 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5755 occurrences of the given element from the list, not just the
5756 first. This is how the Emacs Lisp functions behave, how the
5757 analogous Common Lisp functions behave, and (I believe) how the
5758 older Maclisp functions worked. I realize that this change may
5759 break code, but it seemed better to break it before the Guile
5762 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5763 Their prototypes were already present in gc.h, but they weren't
5765 (scm_init_storage): Initialize scm_protects.
5766 * root.c (scm_protects): New element of scm_sys_protects.
5768 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5770 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5772 * libguile.h: Added #include "libguile/net_db.h".
5774 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5775 30 change. That file is only meant for communication between the
5776 configuration process and load.c. If code linked against libguile
5777 wants to get at the paths mentioned in libpath.h, it can call
5778 functions declared in load.h.
5780 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5782 * libguile.h: Removed #include "libguile/fdsocket.h"
5784 * net_db.c: Added #include <sys/socket.h>.
5786 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5788 * filesys.c (scm_input_waiting_p): use select in preference to
5789 FIONREAD, since the latter doesn't detect EOF.
5790 Throw error if neither select nor FIONREAD available.
5792 * socket.c (scm_connect): take a port, not a fd object.
5793 (scm_fill_sockaddr): throw an error if fam is not recognised.
5794 (scm_bind): use scm_fill_sockaddr.
5795 (scm_listen): take a port, not a fd object.
5796 (scm_accept): take and return a port. return #f in the car if
5797 address can't be got
5798 (scm_sock_fd_to_port): new procedure.
5799 (scm_socket): use scm_sock_fd_to_port.
5800 (scm_addr_vector): throw error if unrecognised address type.
5801 take an extra argument with the calling procedure name.
5802 (scm_getsockname): take a port. return #f if address can't be got.
5803 (scm_getpeername): take a port. return #f if address can't be got.
5804 (scm_recvfrom): take a port. return #f for address component if can't
5806 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5807 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5809 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5811 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5812 use separate data pointers, to allow them to be designed
5813 independently and reused.
5814 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5815 Renamed from catch_body, catch_handler, and uncaught_throw; made
5817 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5819 (scm_catch): Use the above.
5820 (scm_throw): Don't bother printing a message for an uncaught
5821 throw; we establish a default handler in init.
5822 * throw.h (scm_internal_catch): Prototype updated.
5823 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5825 (struct scm_body_thunk_data): New structure, used as data
5826 argument to scm_body_thunk.
5827 * init.c (struct main_func_closure): New structure, packaging up
5828 the data to pass to the user's main function.
5829 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5830 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5831 scm_internal_catch to establish a catch-all handler, using
5832 scm_handle_by_message. This replaces the special-case code in
5834 (invoke_main_func): Body function for scm_internal_catch; invoke
5835 the user's main function, using the main_func_closure pointer to
5836 decide what to pass it.
5837 * root.c (struct cwdr_body_data): Remove handler_proc member.
5838 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5839 (cwdr_handler): Removed.
5841 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5843 * socket.h (SCM_P): update bind prototype.
5844 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5845 include "feature.h".
5846 (scm_socket): return a port, not a file descriptor object.
5847 include "fports.h" and <unistd.h>
5848 (scm_bind): take a port, not a file descriptor object.
5849 take an extra argument for address args.
5851 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5852 INADDR_NONE, INADDR_LOOPBACK.
5854 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5856 * init.c: include net_db.h and not fdsocket.h.
5857 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5859 * Makefile.am: corresponding changes.
5860 * socket.h: renamed from fdsocket.h, fix names.
5861 * net_db.h: renamed from socket.h, fix names.
5862 * socket.c: renamed from fdsocket.c.
5863 remove _sys from procedure names.
5864 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5865 add "socket" to features list.
5866 * net_db.c: renamed from socket.c.
5867 remove _sys from procedure names.
5868 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5869 add "net-db" to features list.
5870 include "net_db.h". don't include <sys/socket.h> or
5873 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5875 * tags.h (scm_tags): Removed comma at end of last enumerator.
5877 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5879 Don't use GCC extensions to allocate space for debugging frames.
5880 (Here he goes again! Why do we put up with this?!)
5881 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5882 an scm_debug_info structure, not an in-line array of them. Add
5883 'info' member, to say how many vect elements we've used, for eval
5885 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5886 a new variable debug_info_end to mark the end of vect, instead of
5887 the address of the 'info' pointer itself.
5888 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5889 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5890 (SCM_APPLY): Explicitly allocate space for debug.vect.
5891 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5892 * stacks.c: Adjusted for new debug frame structure.
5893 (RELOC_INFO, RELOC_FRAME): New macros.
5894 (stack_depth, read_frames): Use them, and new scm_debug_frame
5895 element 'info', instead of magically knowing that eval frames have
5896 an info pointer sitting after vect.
5897 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5899 (scm_init_stacks): Formatting tweaks.
5901 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5903 Give GCC more control flow information, so it can be sure that
5904 variables aren't used uninitialized.
5905 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5906 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5907 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5908 scm_misc_error): Tell GCC that these functions never return.
5909 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5910 out the field type, call abort if SCM_ASSERT returns, to placate
5912 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5913 scm_wta ever returns. We can't handle this case anyway, and this
5914 gives the optimizer more information.
5915 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5916 scm_wta ever returns.
5918 In some cases, the code is fine, but GCC isn't smart enough to
5919 figure that out; this usually happens when one variable is only
5920 initialized and used when a particular condition holds true, and
5921 we know that condition will never change within a given invocation
5922 of the function. In this case, we simply initialize the variables
5923 to placate the compiler, hopefully to a value which will cause a
5924 crash if it is ever actually used.
5925 * print.c (scm_iprin1): Initialize mw_pos.
5926 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5927 * throw.c (scm_ithrow): Initialize dynpair.
5928 * unif.c (scm_uniform_vector_ref): Initialize cra.
5929 * struct.c (init_struct): Initialize prot.
5930 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5932 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5933 if EXPR contains no expressions.
5935 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5937 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5938 cause an infinite loop (???). So much for the algebraic
5939 equivalency of variable-sized arrays and alloca...
5941 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5943 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5944 a SCM boolean, not a C boolean.
5946 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5948 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5949 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5950 rules for raising scm_mtrigger. Previously, unfortunate but not
5951 unlikely circumstances could result in almost constant invokation
5952 of the gc. Now, this situations should be less likely, but they
5953 are not prevented completely.
5955 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5957 * numbers.c (scm_fuck): Procedure removed; looks like old test
5959 * numbers.h: Prototype removed.
5961 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5963 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5964 array to a pointer, to match my Nov 21 change in eval.c.
5966 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5968 * libguile.h: Added #include "libguile/backtrace.h", #include
5969 "libguile/stacks.h".
5971 * strings.c (scm_string scm_make_string scm_string_ref
5972 scm_string_set_x scm_string_equal_p scm_string_append):
5973 Bugfix according to scm patch from Aubrey Jaffer:
5974 Corrected long-standing
5975 (not (eqv? (integer->char 128)
5976 (string-ref (make-string 1 (integer->char 128)) 0)))
5977 bug found by John Kozak <jk@noontide.demon.co.uk>.
5979 * strports.c, strports.h: Make scm_eval_0str return the value of
5980 the last expression evaluated (previously, it returned void).
5982 * strports.c, strports.h: New function: scm_read_0str. Does what
5985 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5987 * simpos.c (scm_getenv): return #f if string can't be found in the
5988 environment instead of throwing an exception, for compatibility
5989 with numerous other systems.
5991 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
5993 * Makefile.am (.c.x): Use guile-snarf.
5994 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
5996 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
5998 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6000 * backtrace.c (scm_display_error_message): Made non-static, and
6001 renamed from display_error_message.
6002 * backtrace.h (scm_display_error_message): Added extern decl.
6003 * throw.c (uncaught_throw): Use it to display the error message.
6005 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6007 * inet_aton.c: Use #if 0, not #ifdef 0.
6009 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6011 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6012 to convert the returned value.
6013 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6014 the offset argument.
6016 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6018 Add new interface to catch/throw, usable from C as well as
6020 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6021 (scm_internal_catch): New function, replaces...
6022 (scm_catch_apply): Deleted.
6023 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6024 mechanism which is a bit more code, but can be used nicely from C
6025 and implement the Scheme semantics as well.
6026 (scm_internal_catch): This is the replacement; it's named after
6027 the analogous function in Emacs.
6028 (scm_catch): Reimplemented in terms of the above.
6029 (struct catch_body_data, catch_body, catch_handler): New
6030 functions, used by scm_catch.
6031 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6032 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6033 support for new cwdr.
6035 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6038 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6040 * acconfig.h: Added DYNAMIC_LINKING symbol.
6041 * configure.in: Add option and checks for dynamic linking.
6042 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6043 dynl.h: New files for dynamic linking support.
6044 * Makefile.am (libguile_a_SOURCES):
6046 (modinclude_HEADERS): Added "dynl.h".
6047 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6049 * init.c (scm_boot_guile_1): Call
6050 scm_init_dynamic_linking to initialize dynamic linking support.
6052 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6054 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6055 (as we Schemers say). It needs to be global, so that I can tweak
6056 it for the proper operation of unexec.
6057 (scm_boot_guile_1_live): New variable, see above.
6059 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6061 * guile-snarf.sh: Removed.
6062 * PLUGIN/guile.libs: Added dependency for -lm.
6063 * acinclude.m4: Renamed from aclocal.m4.
6064 * PLUGIN/greet: Removed.
6065 * Makefile.am, aclocal.m4: New files.
6066 * configure.in: Updated for Automake.
6068 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6070 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6071 and not top_level_lookup_thunk_var.
6073 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6075 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6077 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6079 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6080 Scheme function, instead of syntax. Single argument is now a
6083 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6085 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6086 scm_ra_divide): Properly terminate statements passed as arguments
6087 to IVDEP macros. (Thanks to Bernard Urban.)
6089 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6090 with non-constant sizes. (Thanks to Bernard Urban.)
6092 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6094 It's an "eval closure", not an "eval thunk." A thunk is a
6095 function of no arguments.
6096 * root.h (struct scm_root_state): Renamed
6097 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6098 (scm_top_level_lookup_closure_var): Renamed from
6099 scm_top_level_lookup_thunk_var.
6100 * root.c (mark_root): Uses changed.
6101 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6102 * init.c (scm_start_stack): Uses changed.
6103 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6104 Change scheme-visible name to *top-level-lookup-closure* from
6105 *top-level-lookup-thunk*.
6107 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6109 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6110 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6112 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6114 * gc.c (struct scm_heap_seg_data): Doc fixes.
6116 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6117 sweeping. Then, prepend each segment's free cells to its
6118 freelist, rather than wiping out the old value. (Thanks to Marius
6121 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6122 scm_check_freelist, scm_debug_newcell): New functions and
6123 variables, for debugging freelist problems.
6124 * pairs.h (SCM_NEWCELL): New debugging version added.
6125 * gc.h (scm_debug_newcell): Added extern declaration, used by
6126 debugging version of SCM_NEWCELL.
6128 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6130 On some systems <libc.h> conflicts with <unistd.h>, and should not
6131 be #included at all.
6132 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6133 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6134 * configure.in: Call it.
6135 * posix.c, filesys.c: Use its results to decide whether or not to
6137 * configure, scmconfig.h.in: Rebuilt with autoconf and
6140 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6142 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6143 pointer to the stdio stream before calling scm_setbuf0, so the
6144 latter will be able to retrieve it. I'm surprised this didn't
6145 segfault earlier. (Thanks to Christopher Lee.)
6147 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6149 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6152 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6154 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6155 number of stack narrowing specifier pairs. The first specifier in
6156 a pair controls inner border, the second the outer border. A
6157 number means cut that number of frames, a procedure object means
6158 cut until that object is found in operator position in a frame.
6160 * root.c (cwdr): Bugfix.
6162 * read.c: Recording of positions disabled by default.
6164 * procs.c (scm_closure_p): New function.
6166 * posix.c (scm_tmpnam): New function.
6168 * load.c: Added #include "throw.h".
6169 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6172 * load.c, load.h (scm_read_and_eval_x): New function.
6174 * eval.c: Renamed debug option "deval" to "debug".
6176 (scm_eval_x): `eval!' is no longer accessible from the scheme
6177 level. Motivation: We can't allow operations which introduce
6178 glocs into the scheme level. Guile's type system can't handle
6179 these as data. Use `eval' or `read-and-eval!' as replacement.
6181 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6182 SCM_CONSP since this is a macro!; Set vframe.prev to
6183 scm_last_debug_frame instead of 0. In this way we can look
6184 "above" the virtual start stack frame if we wish.
6185 (scm_debug_hang): New function: Useful for debugging Guile in
6186 certain tricky situations. Will probably be removed later...
6188 * debug.h: Changed semantics of debug option "backtrace". This
6189 option now only indicates whether we want automatic backtrace at
6192 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6194 * ports.c: #include "filesys.h"
6195 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6197 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6198 Motivation: This is system specific code which is related to file
6199 I/O. It also may use select. Added code by Gary Houston to
6200 detect presence of character in stdio buffers.
6202 * libguile.h: #include "libguile/libpath.h"
6204 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6205 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6206 SCM_SITE_DIR; Install libpath.h among the other include files.
6208 * load.c, load.h (scm_sys_package_data_dir): New function.
6210 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6212 * stacks.h: Bugfix: Don't use tail-array length field as stack
6213 length field! This screwed GC.
6215 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6217 * _scm.h: Added #ifndef around definition of macros min and max.
6219 * __scm.h: Added hooks for threads to plugin to in ints protection
6220 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6221 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6222 the main code in these macros duplicated and spread over multiple
6223 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6224 SCM_THREAD_SWITCHING_CODE.
6226 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6228 * snarf.h: New file.
6229 * guile-snarf.sh: New file.
6230 * Makefile.in (inner_h_files): Added snarf.h
6231 (ancillary, install, uninstall, distclean): Added actions for
6233 (.c.x): Use guile-snarf.
6234 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6235 (gen_c_files): Note that these depend on guile-snarf.
6236 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6237 now in "snarf.h". Added #include "snarf.h" to get them.
6238 * libguile.h: Added #include "snarf.h".
6239 (Patches applied and tweaked by Jim Blandy.)
6241 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6243 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6244 standards suggest against providing prototypes for system
6245 functions. Thanks to Greg Troxel.
6247 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6249 * strports.c (scm_eval_0str): New function.
6250 #include "read.h", to get prototype for scm_read.
6251 * Makefile.in (strports.o): Update dependencies.
6252 * strports.h: New prototype.
6254 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6255 scheme name from "int?" to "integer?". It seems to do the job.
6256 * numbers.h: Rename prototype too.
6257 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6260 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6261 scm_num_eq_p): Rename these according to R4RS conventions: call
6262 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6263 to making libguile R4RS compliant without ice-9...
6265 * load.c (scm_sys_search_load_path): Search for files under all
6266 extensions listed in the %load-extensions variable. If FILENAME
6267 is absolute, return it unchanged, without searching the load path.
6268 (scm_loc_load_extensions): New variable, pointing to
6269 %load-extensions' value cell.
6270 (scm_init_load): Initialize it, and the value it points to.
6271 (scm_primitive_load_path): Improve error reporting.
6273 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6274 of new Scheme variable %load-hook.
6275 (scm_primitive_load): Apply %load-hook to filename.
6277 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6279 * configure.in: add tests for figuring out whether buffered data
6280 is available in a FILE structure, which is needed by char-ready.
6282 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6285 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6286 exceptions using misc_error instead of syserror. It seems a bit
6287 odd to throw an exception if a string can't be found in the
6288 environment, but it's consistent with open-file, stat etc.
6289 (simpos.h): remove sys_ from getenv.
6291 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6292 occurs, throw an error instead of returning errno. Return value
6294 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6296 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6298 * filesys.c (scm_stat2scm): derive file type and permissions from
6299 the stat mode and append them to the returned vector.
6300 There isn't much overhead in doing this and it avoids the need to
6301 work with S_IRUSR et al. in Scheme.
6302 Define symbols scm_sym_regular etc.
6303 (scm_init_filesys): don't intern S_IRUSR etc.
6305 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6306 and s_primitive_load_path.
6308 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6310 * error.h: don't declare error symbols. prototype for scm_misc_error.
6312 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6315 * error.c: use SCM_SYMBOL to set up error keys.
6316 scm_misc_error: new procedure.
6318 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6320 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6321 between `#!' and `!#' is ignored.
6322 (skip_scsh_block_comment): New function.
6324 * feature.c (scm_set_program_arguments): New argument, FIRST.
6325 * feature.h: Update prototype.
6326 * init.c (scm_boot_guile_1): Pass new argument to
6327 scm_set_program_arguments.
6329 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6331 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6332 (scm_boot_guile): Call scm_set_program_arguments here, later than
6333 the old initialization.
6335 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6336 initialization procedure.
6337 - Delete in, out, err arguments; there are other perfectly good
6338 ways to override these when desired.
6339 - Delete result argument; this function shouldn't ever return.
6340 - Rename init_func argument to main_func, for less confusion.
6341 - Delete boot_cmd argument; main_func is more general.
6342 -Add 'closure' argument, to help people pass data to main_func
6343 without resorting to global variables.
6344 - Abort if reentered; don't bother returning an error code.
6345 - Call scm_init_standard_ports to set up the default/current
6346 standard ports; no need to pass them to scm_start_stack.
6347 - Remove code to evaluate the boot_cmd, and start the repl; let
6348 the user do something like that in main_func if they want.
6349 - Remove code to package up a return value; main_func can do any
6351 - Call exit (0), instead of returning.
6352 (scm_start_stack): Don't initialize the I/O ports here; that's
6353 weird. Delete in, out, err arguments. Move guts to
6354 scm_init_standard_ports, scm_stdio_to_port.
6355 (scm_init_standard_ports): New function, to set up current and
6356 default standard ports.
6357 (scm_start_stack, scm_restart_stack): Make these static.
6358 * init.h (scm_boot_guile): Adjust declaration.
6359 (scm_start_stack, scm_restart_stack): Remove externally
6360 visible declarations for these.
6361 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6363 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6364 written out several times in scm_start_stack.
6365 * fports.h: New declaration for the above.
6367 * feature.c (scm_set_program_arguments): New function.
6368 * feature.h: New declaration for the above.
6370 * ports.c: Formatting tweak.
6372 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6374 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6375 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6376 for obtaining the address of a car or cdr field. Motivation:
6377 &SCM_CXR make assumptions about the internal structure of the
6380 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6381 Motivation: see SCM_CXRLOC.
6383 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6384 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6385 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6386 Motivation: Safer use. Some other macros are defined in terms of
6387 these operations. If these are defined using the SCM_SETCXR
6388 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6389 to inefficiency and an <e1> with side-effects could potentially
6390 break. Also, these particular operations are heavily utilized in
6391 the garbage collector. In unoptimized code there will be a
6394 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6395 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6396 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6397 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6398 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6399 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6400 vports.c: Cleaned up use of pairs: Don't make any special
6401 assumptions about the internal structure of selectors and
6402 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6403 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6404 (Among other things, this change makes it easier to build Guile
6405 with certain compilers which have problems with casted lvalues.)
6407 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6409 * stacks.c: Improve selection of relevant stack frames when making
6410 a stack object. Introduce one level of indirection in the stack
6411 object to make it possible to "narrow" to a certain region of the
6412 stack. This facilitates making use of more clever algorithms (not
6413 implemented) for selecting relevant frames and gives a cleaner
6414 design since selection of frames can be done independently of
6415 extraction of frames from the real stack.
6416 (scm_stack_id): Also take #t as argument which means look at
6419 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6420 Turn n_tail into an integer directly representing current number
6421 of frames in stack. Add field tail.
6423 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6425 * debug.c (scm_make_memoized): Made it available at scheme level.
6426 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6427 SCM_NIMP before applying heavier predicates in argument checking.
6428 (scm_local_eval): Also take memoized object as argument.
6430 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6431 aren't created with zero length, but should such a strange
6432 creature suddenly turn up...
6434 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6436 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6437 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6439 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6441 * variable.c (scm_make_variable): Make the name hint optional, as
6443 (anonymous_variable_sym): Renamed from variable_sym. All uses
6446 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6447 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6448 of scm_primitive_load_path was also changed to
6449 "primitive-load-path", from "%try-load-path". Callers changed.
6450 We'd like to respect the convention that a function named
6451 "try-mumble" should behave just like the function called "mumble",
6452 but return #f instead of signalling some error.
6453 * load.h: Rename prototypes.
6455 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6457 * print.c (make_print_state, grow_print_state), print.h: Modified
6458 the print state representation: Don't use a tail array for
6459 recording of circular references. Resizing of the print state
6460 structure invalidates the print state pointer. To avoid passing
6461 around an indirect print state reference to all printing
6462 functions, we instead let the print state reference a resizable
6465 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6467 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6468 Don't crash when passed an improper list terminated by a
6469 non-immediate value.
6471 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6473 Allocate data for structures on an eight-byte boundary, as
6474 required by the tagging system.
6475 * struct.c (alloc_struct): New function.
6476 (scm_make_struct, scm_make_vtable_vtable): Call it.
6477 * struct.h (scm_struct_n_extra_words): Bump to 3.
6478 (scm_struct_i_ptr): New "field".
6479 * gc.c (scm_gc_sweep): When we need to free the data, use the
6480 information stored by alloc_struct to find the beginning of the
6481 block allocated to the structure, so we can free it.
6483 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6485 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6488 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6489 (scm_debug_info): New member: id.
6491 * stacks.c: Stacks are now represented as structs; Stacks have an
6492 id given to them by `start-stack'.
6493 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6495 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6496 Changed stack representation.
6498 * debug.c (scm_procedure_name): Try procedure property `name' for
6499 compiled closures aswell.
6501 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6503 * eval.c: scm_i_name moved to gsubr.c
6504 (scm_m_define): Record names of all kinds of procedure
6505 objects. (Earlier, only closures were recorded.)
6507 * procprop.h: Added declaration of scm_i_name.
6509 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6510 (scm_make_gsubr): Record names of compiled closures.
6512 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6514 * debug.c, debug.h: Removed obsolete code.
6516 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6517 stacks.c: Renamed regs --> scm_contregs.
6519 * print.c (scm_free_print_state): Cleanup print state before
6520 returning it to pool. It is better to do it here than in
6521 scm_prin1 since scm_prin1 is called often.
6523 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6524 s_set_source_property_x): Check that first argument is a pair or a
6527 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6528 scm_i_line, scm_i_column and scm_i_breakpoint global.
6530 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6531 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6534 * debug.h: Added debug object smob declaration and macro
6537 * configure.in: Build with backtrace.o and stacks.o if debug
6540 * Makefile.in: Added entries for new files: backtrace.c,
6541 backtrace.h, stacks.c and stacks.h.
6543 * symbols.c (scm_sym2ovcell): Fixed documentation.
6545 * _scm.h (min, max): Added.
6547 * async.c: Moved `min' macro to _scm.h.
6549 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6550 SCM_BACKTRACE_INDENT.
6552 * eval.c: Added new debug options `maxdepth' and `indent'.
6554 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6556 * print.h: Added selector SCM_PRINT_STATE.
6558 * print.c: New functions: scm_make_print_state,
6559 scm_free_print_state.
6561 * print.h: Added declarations for scm_make_print_state,
6562 scm_free_print_state.
6564 * debug.c (scm_m_start_stack): New acro.
6566 * debug.h: Small cleanup.
6568 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6571 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6593 declare functions with prototypes. (Patch thanks to Marius
6596 More prototype-related changes from Marius Vollmer:
6597 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6598 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6599 * ports.h (ptobfuns): Added prototypes. This means some casting in
6601 * fports.c: Added casts for initializations, since the functions
6602 are defined to take FILE * as their stream argument, not SCM.
6603 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6604 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6605 to `char *str_data' to conform to prototype.
6607 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6609 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6611 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6613 * stime.c, stime.h: use SCM_P method.
6615 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6617 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6618 be given at least two arguments. Insist that lst's last element
6619 be a list, but don't make any requirements of its predecessors.
6621 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6623 * eval.c (scm_nconc2last): Revert last change; there seems to be
6624 other stuff going on here.
6626 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6628 * eval.c (scm_nconc2last): Make sure that each element of lst
6629 (which is a list of argument lists, except for the tail) is a
6630 proper list, i.e., finite and terminated by '().
6632 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6634 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6637 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6638 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6641 * vectors.c (scm_make_vector): Fill vectors with the undefined
6642 value, to help make Guile Scheme code more portable to other
6645 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6646 * symbols.h, tags.h: Doc fixes.
6648 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6650 * async.c (scm_take_signal): Doc fixes.
6652 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6654 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6655 want to subtract it from the modulus; we just want to leave it
6658 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6660 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6663 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6665 * throw.c (scm_catch_apply): Finished implementation of
6668 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6670 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6672 (scm_init_filesys): set "i/o-extensions" feature.
6675 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6677 * Makefile.in (root.o): Correct dependencies.
6679 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6681 * Makefile.in: Added dependency entry for root.o.
6683 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6684 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6686 * init.c (scm_start_stack): Set initial root continuation number
6689 * procs.c: New function: scm_thunk_p.
6691 * procs.h: Added declarations of scm_thunk_p.
6693 * root.c: Renamed `call-with-new-root' -->
6694 `call-with-dynamic-root'.
6695 (cwdr): Removed allocation of new root state. This should be done
6696 separately by use of scm_make_root.
6697 (scm_apply_with_dynamic_root): New function: Does what it
6698 sounds like. Needed when spawning threads.
6700 * root.h: Added member last_debug_frame to root state.
6701 Added #include "libguile/debug.h"
6703 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6704 arguments. The motivation is that code in root.c needs catch
6705 functionality, and we want to avoid code duplication.
6706 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6707 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6708 handlers that run without popping the stack into the dynwind
6711 * throw.h: Added prototypes for scm_catch_apply and
6714 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6716 * root.h (scm_root, scm_set_root): Decouple thread support details
6717 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6718 SCM_SET_THREAD_LOCAL_DATA.
6720 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6721 and tortoise scanning loop.
6723 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6725 * Makefile.in: Rebuild dependencies.
6727 * libguile.h: #include "libguile/print.h" before "smob.h", since
6728 the latter uses the print_state structure.
6730 * throw.c (scm_ithrow): Use the correct variable when checking to
6731 see if a given element of scm_dynwinds is a valid catch.
6733 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6734 structure, abort; don't just silently ignore the garbage.
6736 * _scm.h: #include "print.h" here, since it seems to be used just
6738 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6739 strports.c, unif.h: Don't #include "print.h".
6741 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6743 * feature.h (scm_loc_features): Removed external declaration.
6744 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6746 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6748 * feature.c (scm_init_feature): Added threads feature (needs to be
6749 initialized here, since features doesn't exist when
6750 scm_init_threads is called).
6752 * libguile.h: Added #include "libguile/../threads/threads.h".
6753 (This is a kludge to get thread support working. This should be
6756 * configure.in, acconfig.h: Added flags for thread support.
6758 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6761 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6762 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6765 * _scm.h: Added conditional #include "threads.h"
6767 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6768 SCM_THREADS_SWITCHING_CODE.
6770 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6771 allocate the basic dynamic root object.
6772 (scm_boot_guile): Added call to scm_init_root.
6774 * root.c, root.h: Added root smob.
6775 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6776 functions: Implements dynamic roots mostly according to spec in
6777 SCM manual. Main difference is that the second argument is a
6778 throw handler rather than an error "thunk".
6780 * root.h: Added declaration of scm_init_root.
6782 * root.c: Added #include "genio.h", #include "smob.h", #include
6783 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6785 (scm_init_root): Added #include "root.x".
6787 * throw.c: Added #include "stackchk.h"
6788 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6789 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6790 can be used in scm_call_with_new_root; Added reenabling of stack
6791 checking when catching a throw.
6793 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6795 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6797 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6798 element is not found, as per R4RS.
6800 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6802 * list.c: Doc fixes throughout.
6804 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6806 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6807 declare the char * to be const. Avoids a warning in rgx.c.
6809 * ports.h: spelling fix.
6811 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6814 * load.c (scm_sys_try_load_path): throw an error if file not found
6815 (like it says it in NEWS).
6817 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6819 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6820 PROPS slot to '(), not #f; it's an empty alist.
6822 * throw.h, throw.c: Use SCM_P instead of #if hair.
6824 Remove special support for uncaught throws; see throw.c for
6826 * throw.c (uncaught_throw): New function.
6827 (scm_ithrow): Call uncaught_throw if we don't find a throw
6828 target; don't mess with scm_bad_throw_vcell.
6829 (scm_bad_throw_vcell): Variable deleted.
6830 (scm_init_throw): Don't initialize it.
6832 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6835 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6837 * numbers.c (scm_istr2int): If the number is short (as most
6838 numbers are), just call scm_small_istr2int to deal with it.
6839 (scm_small_istr2int): New function, created by un-#ifdefing the
6840 non-bignum version of scm_istr2int and renaming it.
6842 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6844 * load.c (scm_sys_try_load): don't check whether value returned
6845 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6846 Change the Scheme name from %try-load to primitive-load.
6848 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6849 Can avoid passing a message, allowing it to be derived in the
6850 error handler (e.g., if we want to throw to the key both from
6853 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6855 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6856 references now have a new appearance which is more compact and
6857 also gives a clue about what the target of the reference is.
6858 By setting parameters in the print state, more fancy printing can
6859 be achieved. This is used by the (not yet commited) backtrace
6862 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6864 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6867 * print.c: Added #include "struct.h". Removed function
6870 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6871 scm_iprin1. Removed prototype for scm_prlist.
6873 * arbiters.c (prinarb),
6874 async.c (print_async),
6875 debug.c (prindebugobj, prinmemoized),
6876 eval.c (prinprom, prinmacro),
6877 filesys.c (scm_fd_print, scm_dir_print),
6879 mallocs.c (prinmalloc),
6880 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6881 smob.h (scm_smobfuns),
6882 srcprop.c (prinsrcprops),
6884 unif.c, unif.h (scm_raprin1, rapr1),
6885 variable.c (prin_var): Changed argument `int writing' to
6886 `scm_print_state *pstate'.
6888 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6889 that it will be called before scm_init_print.
6891 * print.c (scm_prin1): Print states are now allocated when calling
6892 scm_prin1 and then passed around to all printing functions as an
6893 argument. A cache `print_state_pool' enables reuse of print
6895 (scm_make_print_state): New function.
6896 (scm_iprin1): Adaption to print states.
6897 (scm_iprlist): An initial "hare and tortoise" scan brings down
6898 time complexity to O (depth * N). (Better time complexity will be
6899 achieved when the printing code is completely rewritten.)
6901 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6903 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6904 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6905 it gets done whether or not the cache variable has a value.
6907 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6909 Distinguish #f and ().
6910 * __scm.h: #undef SICP.
6911 * pairs.h (SCM_EOL): Delete this definition, equating it with
6913 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6914 the value it used to have. Doc fixes, too.
6916 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6918 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6919 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6920 Lord's implementation of structs, allowing for tail arrays as
6921 described in the manual. Also fixed some bugs. (Both the interface
6922 and the implementation should be improved.)
6924 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6926 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6927 People who whish to see the source can do `(print-enable 'source)'.
6928 Removed #ifdef DEBUG_EXTENSIONS.
6930 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6932 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6933 integer (assuming for now accepting an integer is a good thing).
6935 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6936 %S will be used instead for write'ing arguments.
6938 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6939 asserts. fix a few other asserts.
6940 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6941 scm_uniform_vector_ref, scm_array_set_x,
6942 scm_dimensions_to_unform_array): change args in
6943 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6944 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6945 scm_substring_fill_x): likewise.
6946 gsubr.c (scm_gsubr_apply): likewise.
6947 eval.c (SCM_APPLY): likewise.
6949 * eval.c (4 places): replace scm_everr with lgh_error or
6952 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6953 scm_memory_error): new procedures.
6954 scm_everr: deleted. can use scm_wta, dropping first two args.
6955 scm_error: convert NULL subr to SCM_BOOL_F.
6957 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6960 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6963 * error.c, error.h: new error keys: scm_arg_type_key,
6964 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6966 scm_wta: reimplement using lgh_error instead of scm_everr.
6968 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6970 * gdbint.c: scm_lread now has one more argument.
6972 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6973 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6974 loading source from non-file ports, which, e. g., happens when
6975 using the Emacs interface).
6977 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6980 * read.c: Added code for recording of positions of source code
6981 expressions; New functions: recsexpr, scm_lreadrecparen;
6982 _scm_make_srcprops --> scm_make_srcprops
6983 (scm_flush_ws): Removed updating of positions counters. This work
6984 is already done by scm_gen_getc
6986 * read.h: Added prototype for scm_lreadrecparen
6988 * print.c: Added #include "alist.h"
6990 * eval.c: Added #include "hash.h"
6992 * eq.c: Added #include "ramap.h"
6994 * options.c: Documentation fixes.
6996 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
6997 (scm_init_srcprop): Adjusted size of initial source-whash. Name
6998 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
6999 --> scm_make_srcprops
7001 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7002 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7003 function calls in the definition of the whash access macros.
7005 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7007 * init.c (scm_boot_guile): Add level of indirection to
7008 scm_boot_guile_1() to ensure that stack base pointer is properly
7009 initialized. There was no guarantee that variable i was the
7010 highest/lowest variable on stack (i.e. the call frame of
7011 scm_boot_guile was not completely protected from gc).
7013 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7015 * ports.h (scm_port_table): put back file_name, it will be used to
7016 support debugging. Undo related changes in fports.c, ioext.c,
7019 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7021 * ports.h (scm_port_table): remove file_name member for now, it seems
7023 * fports.c (scm_open_file): don't set file_name in PTAB.
7024 (prinfport): don't use file_name in PTAB.
7025 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7026 * ports.c (scm_add_to_port_table): don't intialize file_name.
7027 (scm_port_file_name): remove for now.
7028 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7030 * fports.h (scm_mkfile): prototype deleted.
7031 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7033 * debug.c, unif.c: use scm_out_of_range instead of
7034 wta for range errors (ASSERT still needs work).
7036 * error.c, error.h (scm_out_of_range): new procedure.
7038 * error.c, error.h (scm_out_of_range_key): new key.
7040 * posix.c (scm_sync): #else was missing.
7042 * error.c, error.h: append _key to names scm_num_overflow and
7045 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7046 of consing an empty list.
7047 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7048 of macros, saves code and string space.
7049 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7050 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7051 lower case. Rename scm_syserror_m to scm_syserror_msg.
7052 error.h: prototypes for new procedures.
7054 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7056 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7058 * error.c, error.h: setup scm_num_overflow key.
7060 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7061 Remove definition of SCM_OVSCM_FLOW.
7063 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7065 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7066 explicit message and args.
7068 * error.c, error.h, __scm.h: change system_error_sym to
7071 * error.c (system_error_sym): remove leading %% from the Scheme name
7074 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7076 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7078 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7079 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7080 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7081 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7082 renamed. (These were introduced by unsupervised name
7085 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7087 * print.c: Added code for detection of circular references during
7088 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7089 a hook for printing of closures (accessible via print options).
7090 This leads to a split of calls to scm_iprin1 into two classes:
7091 elementary print operations (e. g. the code which prints a smob)
7092 still use scm_iprin1 while top level calls (like scm_display) use
7093 scm_prin1. scm_prin1 begins by clearing the data structure used
7094 to record reference information.
7096 * print.h: Added declarations of scm_prin1 and scm_prlist.
7098 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7100 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7102 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7104 * error.c (err_head): scm_iprin1 --> scm_prin1
7106 * debug.c: Adjusted header comment.
7110 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7112 * strerror.c: Doc fix.
7114 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7116 * gdbint.c (gdb_read): Now possible to run during GC.
7117 (unmark_port, remark_port): New functions.
7119 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7121 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7122 of allocating a new string object. Also, increase size by
7123 the factor 2 instead of 1.5.
7125 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7127 * __scm.h (SCM_P): Corrected to run under traditional C.
7129 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7132 * async.c: Calls to scm_sysintern corrected.
7134 * async.h (scm_async_clock): Redundant declaration removed.
7136 * continuations.c (scm_dynthrow): Redundant declaration removed.
7138 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7139 Definition typos corrected.
7141 * debug.h: Missing declarations of functions in debug.c added
7144 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7145 Missing declarations to functions in eval.c added.
7147 * filesys.c: Possibly uninitialized variable rv.
7149 * gc.h (scm_object_addr, scm_unhash_name): Missing
7150 declarations of functions defined in gc.c added.
7152 * genio.c: Possible typos str_data -> wstr_data. ???
7154 * genio.c: Possibly unintended shadowing of local variable
7155 `int c' (gotos out of scope of inner `c'). ???
7157 * init.c: Uninitialized `SCM last' may be used.
7159 * ioext.h: (scm_sys_isatty_p): Typo.
7161 * list.h (scm_list_head): Missing prototype for function in
7164 * numbers.c (scm_two_doubles): Changed from extern to static
7165 (is used only within numbers.c).
7167 * numbers.h: Repeated declarations removed.
7169 * ports.h (scm_close_all_ports_except): Declaration for the
7170 function defined in ports.c added.
7172 * posix.h: Missing declarations added.
7174 * procs.h (scm_make_subr_opt): Missing declaration added.
7176 * socket.h (scm_sys_gethost): Missing declaration added.
7178 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7180 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7181 Missing declarations added.
7183 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7185 * struct.c: Uninitialized variable `SCM answer' may be used.
7187 * unif.c (l2ra): Declaration prototype.
7189 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7190 defined in ramap.c).
7192 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7193 Redundant declarations removed (they are in ramap.h).
7195 * variable.h (scm_make_udvariable,
7196 scm_make_undefined_variable): Declaration corrected to
7197 correspond variable.c.
7199 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7200 Missing declarations added.
7202 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7204 * Makefile.in (distclean): Don't forget to delete fd.h.
7206 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7208 * fd.h.in, tags.h: Trivial cleanups.
7210 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7211 marksweep.h just declared functions from gc.c.
7212 * gc.h, libguile.h: Don't #include "marksweep.h".
7213 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7214 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7215 dependencies updated.
7217 * libguile.h: Don't #include "files.h"; it's been deleted.
7219 * files.c (scm_sys_delete_file): Moved to filesys.c.
7220 File is now empty; deleted.
7222 * filesys.c: scm_sys_delete_file is now here. Remove
7223 #if's; they seem to rely on remnants of an old portability
7224 regimen. If the problems come up again, solve them properly,
7225 using autoconf. Specifically: Don't test M_SYSV, and #define
7226 remove to be unlink if it's #defined; don't use remove just
7227 because HAVE_STDC_HEADERS is #defined.
7228 * filesys.h: Add declarations for scm_sys_delete_file.
7229 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7230 files.o, files.h, files.c, and files.x.
7231 * init.c: Don't #include "files.h", and don't call scm_init_files.
7233 Use SCM_P instead of PROTO; the latter intrudes on the user's
7235 * params.h: Deleted; definition of SCM_P moved to...
7236 * __scm.h: ... here, where it replaces PROTO macro.
7237 * libguile.h, smob.h: Don't #include "params.h".
7238 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7239 smob.h: Fix prototypes accordingly.
7240 * Makefile.in: Update dependencies.
7241 (inner_h_files): Remove params.h.
7243 * gc.c: #include "gc.h"; every module should include its header,
7244 to let the compiler cross-check the declarations against the
7247 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7248 simpos.h: #include "libguile/__scm.h".
7250 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7252 * init.c: Don't forget to #include smob.h and init.h.
7253 * Makefile.in: Dependencies updated.
7255 * smob.h: Use PROTO instead of #if __STDC__.
7257 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7259 * __scm.h: Doc fixes.
7261 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7262 <angles>; this allows `make depends' to work properly.
7264 * libguile.h: #include smob.h and pairs.h before the others; they
7265 define typedefs used by other headers.
7267 C files should #include only the header files they need, not
7268 libguile.h (which #includes all the header files); the pointless
7269 recompilation was wasting my time.
7270 * Makefile.in (all .o dependency lists): Regenerated.
7271 * libguile.h: Don't try to get a definition for size_t here...
7272 * __scm.h: Do it here.
7273 * _scm.h: Since this is the internal libguile header, put things
7274 here that all (or a majority) of the libguile files will want.
7275 Don't #include <libguile.h> here; that generates dependencies on
7276 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7277 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7278 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
7280 * alist.c: Get "eq.h", "list.h", "alist.h".

7294 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".

7299 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
7300 * feature.c: Get "feature.h".
7301 * files.c: Get "files.h".
7302 * filesys.c: Get "filesys.h", "smob.h", "genio.h".
7303 * fports.c: Get "fports.h", "markers.h".

7312 * init.c: Get everyone who has an scm_init_mumble function:
7313 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
7314 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

7379 * print.h, read.h: #include "options.h", since everyone who uses
7380 either of these files will need that.
7382 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7383 anyone who uses this file will need them to define the smob
7384 printing functions. Also, get markers.h, since people will need
7385 to #define the mark functions.
7387 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7388 * ports.h: ... to here.
7390 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7391 don't rely on archaic C default type rules.
7393 * fports.h: #include "libguile/ports.h", since you need that in
7394 order to parse this.
7396 * genio.h: #include "libguile/print.h", because you need that to
7397 parse this; don't bother #including "ports.h", since print.h gets
7400 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7402 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7403 this; it's now a reference to an element of *scm_root.
7405 * debug.h: Don't #include "options.h"; the compiler won't be able
7406 to find that once the headers are installed; instead, #include
7407 "libguile/options.h".
7408 * gc.h: Same, with marksweep.h.

7410 * scmhob.h: Same, with _scm.h.
7411 * smob.h: Same, with params.h.
7413 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7414 C files; there's no need for this, and it forces recompilations
7417 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7419 * error.c (scm_error): declare scm_error_callback.
7421 * error.h: prototype for scm_error_callback.
7423 * __scm.h: define lgh_error.
7424 (SCM_SYSERROR): redefine using lgh_error.
7426 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7428 * error.c (scm_error): new procedure.
7430 * error.h: prototype for scm_error.
7432 * Makefile.in (install): install scmconfig.h from the current
7433 directory, not $(srcdir).
7435 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7437 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7438 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7439 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7445 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7446 vports.h, weaks.h: #include "libguile/__scm.h", not
7447 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7448 dependencies are within libguile properly.
7450 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7452 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7453 when scmconfig.h doesn't exist.
7455 * load.c (scm_sys_try_load): Correct spelling.
7457 * feature.c (scm_loc_features): Make this static.
7459 * Makefile.in (libpath.h): Omit trailing slash from path. We
7460 shouldn't require it of users, so why put it here?
7462 Move code to initialize and search %load-path from ice-9 to C
7463 code, so we can use the load-path to find the ice-9 boot code;
7464 this makes it easier to run Guile without installing it. See
7465 corresponding changes in guile/Makefile.in.
7466 * feature.c: Move stuff concerned with the load path to load.c.
7467 (scm_compiled_library_path): Deleted.
7468 Don't #include libpath.h here.
7469 * feature.h: Don't mention scm_compiled_library_path.
7470 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7471 <sys/stat.h>, and <unistd.h> (if present).
7472 (R_OK): #define if the system hasn't deigned to.
7473 (scm_loc_load_path): New variable.
7474 (scm_init_load_path, scm_sys_search_load_path,
7475 scm_sys_try_load_path): New functions.
7476 (scm_init_load): Initialize scm_loc_load_path to point to the
7477 value cell of the Scheme %load-path variable.
7478 * load.h: Add declarations for scm_sys_search_load_path,
7479 scm_sys_try_load_path.
7480 * init.c: Call scm_init_load_path.
7481 * Makefile.in (feature.o, load.o): Dependencies updated.
7483 * load.c, load.h: Rewrite using PROTO macro.
7485 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7487 * gc.c (scm_cellp): New function: C predicate to determine if an
7488 SCM value can be regarded as a pointer to a cell on the heap.
7490 * gc.h: Added declaration of scm_cellp.
7492 * gdb_interface.h: New file: The GDB interface header from the GDB
7495 * gdbint.c: New file: GDB interface.
7497 * gdbint.h: New file: GDB interface.
7499 * libguile.h: Added #include <libguile/gdbint.h>.
7501 * init.c (scm_boot_guile): Added scm_init_gdbint.
7503 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7504 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7505 found if object files and source are kept separate).
7507 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7509 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7511 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7513 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7514 TK_SRC_DIR; they're not relevant any more.
7516 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7517 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7519 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7521 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7522 search path, so we can find the <libguile/MUMBLE.h> headers.
7524 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7526 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7527 implicit in the .c.o rule.
7528 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7531 Put the library path in a header file, instead of passing it on
7532 the command line in every compilation.
7533 * Makefile.in (libpath.h): New target.
7534 (feature.o): Depend on libpath.h.
7535 (clean): Delete libpath.h.
7536 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7537 * feature.c: ... #include "libpath.h" here.
7538 * .cvsignore: Ignore libpath.h.
7540 Don't install the unwashed masses of Guile header files in the
7541 main #include path; put most of them in a subdirectory called
7542 'libguile'. This avoids naming conflicts between Guile header
7543 files and system header files (of which there were a few).
7544 * Makefile.in (pkgincludedir): Deleted.
7545 (innerincludedir): New variable; this and $(includedir) are enough.
7546 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7547 (installed_h_files): Divide this up. Now this variable lists
7548 those header files which should go into $(includedir) (i.e. appear
7549 directly in the #include path), and ...
7550 (inner_h_files): ... this new variable says which files appear in
7551 a subdirectory, and are referred to as <libguile/mumble.h>.
7552 (h_files): List them both.
7553 (install): Create innerincludedir, not pkgincludedir. Put
7554 the installed_h_files and inner_h_files in their proper places.
7555 (uninstall): Corresponding changes.
7556 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7557 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7558 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7559 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

7562 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7563 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7564 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7565 vports.h, weaks.h: Find __scm.h in its new location.
7566 * __scm.h: Find scmconfig.h and tags.h in their new locations
7567 (they're both "inner" files).
7569 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7571 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7573 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7575 * posix.c: Doc fixes.
7577 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7579 * socket.c: Don't include a prototype for inet_aton; just use a
7580 K&R style declaration, to avoid warnings but minimize the chance
7581 of conflicts with the system.
7583 On NextStep, <utime.h> doesn't define struct utime, unless we
7584 #define _POSIX_SOURCE before #including it.
7585 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7586 * acconfig.h: New comment text for above CPP symbol.
7587 * configure.in: Call it.
7588 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7590 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7592 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7593 testing for __EMX__.
7595 * posix.c: #include <libc.h>, if it exists.
7597 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7598 don't even know if the latter exists.
7600 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7601 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7602 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7604 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7606 (scm_init_posix): Use them when initializing the Scheme constants
7609 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7611 * Makefile.in (libdir, includedir, bindir): Use the
7612 autoconf-supplied values, instead of deriving them ourselves.
7613 (pkgincludedir, datadir, pkgdatadir): New variables.
7614 (install, uninstall): Put the header files in a special
7615 subdirectory, not in the main search path.
7617 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7618 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7620 * Makefile.in (IMPLPATH): Deleted; never used.
7622 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7623 on the Tcl/Tk source any more.
7624 (INCLUDE_CFLAGS): Remove references to the above.
7626 * Makefile.in (version.o): Corrected dependencies.
7628 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7630 * libguile.h: #include "version.h"
7632 * init.c (scm_boot_guile): Call scm_init_version.
7633 * gscm.c (gscm_run_scm): Call scm_init_version.
7635 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7636 GUILE_VERSION): AC_DEFINE these.
7637 (acconfig.h): #undef the above symbols.
7639 * Makefile.in (libobjs): Add version.o.
7640 (installed_h_files): Add version.h.
7641 (c_files): Add version.c.
7642 (gen_c_files): Add version.x.
7643 (version.o): New rule.
7644 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7645 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7654 weaks.o): Add version.h to dependency lists.
7655 (markers.o): Remove duplicate rule.
7657 * version.h: New file.
7659 * version.c: New file.
7661 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7663 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7664 array; use it appropriately. Since GCC is quite happy to
7665 subscript functions, it never warned us about this; we should use
7666 -Wpointer-arith in the future. I guess we never tested
7669 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7671 * socket.c: Doc and copyright fixes.
7673 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7675 * debug.c: Fixed and improved gdb support.
7677 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7679 * socket.c: Added declaration of inet_aton to avoid compiler
7680 warning. (Hope this solution is correct.)
7682 * stime.c: Added declaration of ftime. (This is missing in
7685 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7687 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7689 * Makefile.in (c_files): add strerror.c.
7691 * strerror.c: new file from Emacs' sysdep.c.
7692 maybe configure should also check for sys_errlist.
7694 * configure.in (AC_REPLACE_FUNCS): add strerror.
7696 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7698 * debug.c (scm_init_debug): Added initialization for
7699 scm_evaluator_traps.
7701 * debug.h, debug.c: Various name changes.
7702 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7703 "debug-options-interface". See commentary in options.c.
7705 * options.h, options.c: Options now have documentation strings.
7706 Also added a long explanatory commentary.
7708 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7711 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7712 last_debug_info_frame is now updated in all cases.
7714 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7717 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7719 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7720 Added option STACK_CHECKING.
7722 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7724 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7726 * __scm.h: Removed symbols for debugging support.
7728 * acconfig.h: Added symbols for debugging support.
7730 * configure.in: Added user option for debugging support.
7731 --enable-debug will include the debugging code into libguile.a.
7733 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7734 scm_relocate_chunk_to_heap.
7736 * debug.c: New file: low-level debugging support. It also
7737 includes support for debugging with gdb. (The extensions to gdb
7738 are written by Per Bothner at Cygnus.)
7740 * debug.h: New file: low-level debugging support.
7742 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7743 argument pairs. Extensive modifications to the debugging
7744 evaluator. Added "SECTION:" commentaries to clarify what happens
7745 when, during double compilation. Renamed EVALIMP --> EVALIM.
7746 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7747 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7748 the beginning of the file. New procedure: scm_unmemocopy.
7749 Added some global state variables needed by the debugging
7750 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7751 check_entry, check_apply, check_exit, debug_options and
7752 evaluator_traps. New acro: undefine.
7754 * eval.h: Renamed EVAL --> XEVAL.
7756 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7757 --> scm_make_weak_key_hash_table.
7759 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7760 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7762 * libguile.h: Conditionally include debug.h
7764 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7765 scm_object_properties shouldn't return handle. `handle' now gets
7766 initialized in scm_set_object_properties_x. scm_object_properties
7767 doesn't any longer create an entry in scm_object_whash.
7769 * options.c: New file: handling of run time options.
7771 * options.h: New file: handling of run time options.
7773 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7775 * print.c: New procedure: scm_print_options
7777 * print.h: Defines for print options.
7779 * read.c: New procedure: scm_read_options
7781 * read.h: Defines for reader options.
7783 * root.h: Added scm_source_whash among scm_sys_protects.
7785 * srcprop.c: New file: source properties.
7787 * srcprop.h: New file: source properties.
7789 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7790 (Bug found by A. Green.)
7792 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7794 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7796 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7798 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7800 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7801 and should be called by the final client.
7803 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7805 * gc.h: Use the PROTO macro when declaring functions.
7806 * gc.c: Use the PROTO macro when declaring static functions.
7807 Remove the CPP hair around function definitions.
7809 * gc.c (scm_init_storage): Initialize scm_asyncs.
7811 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7812 preprocessor symbol; "__scm.h" is where it might get #defined.
7813 * __scm.h: Similar: #include <scmconfig.h> before testing
7816 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7818 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7820 * init.c (scm_boot_guile): Add init_func argument; call
7821 (*init_func) instead of calling scm_appinit; it's ucky to
7822 hard-code names for the user's procedures.
7823 * init.h (scm_boot_guile): Adjust declaration.
7825 * __scm.h (PROTO): New macro, for declaring functions with
7828 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7829 eliminate all the __STDC__ conditionals.
7830 (scm_boot_guile): Add declaration.
7831 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7832 Remove __STDC__ conditionals around function definitions; the
7833 declarations in init.h will provide the same information, more
7836 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7837 complain about it in the error message; the error message is
7838 adequate without that note, and there's nothing the user can do
7841 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7843 * Makefile.in (ancillary): Drop def.sed.
7845 * posix.c (scm_init_posix): Use numeric values, rather than
7846 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7847 F_OK. The symbols aren't available on some systems, and I'm
7848 pretty sure their values are fixed by common widespread practice.
7849 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7851 More functions unavailable on some systems.
7852 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7853 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7855 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7856 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7857 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7858 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7859 stub that signals an error as the #else.
7861 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7863 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
7865 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
7867 * unif.c: include ramap.h.
7869 * read.c (endif): case_insensative_p renamed case_insensitive_p.
7871 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
7873 * ports.c: include sys/ioctl.h.
7875 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
7877 * configure.in: check for sys/ioctl.h.
7879 * ports.c: include <malloc.h> not "malloc.h".
7881 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7883 * fports.c: remove ttyname and tmpnam declarations.
7885 * posix.c: fewer ttyname declarations.
7887 * fports.c: include <string.h> not "string.h".
7889 * init.c, ioext.c: include string.h and unistd.h.
7891 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
7893 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
7894 genio.c, simpos.c, vports.c: include string.h.
7896 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
7898 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
7900 (scm_addr_buffer_size): change type from scm_sizet to int.
7901 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
7902 from scm_sizet to int.
7904 * error.c: include unistd.h.
7906 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
7909 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
7911 * __scm.hd, def.sed: deleted.
7913 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
7915 Changes for NeXT, suggested by Robert Brown.
7916 * configure.in: Call AC_TYPE_MODE_T.
7917 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
7918 NeXT. Put header file list in alphabetical order.
7919 * configure, scmconfig.h.in: Regenerated.
7920 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
7922 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
7925 * acconfig.h: New file, providing documentation for the CPP
7926 symbols defined in configure.in
7927 * acconfig-1.5.h: Removed; superceded by the above.
7929 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
7931 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
7933 * fports.c (scm_open_file): don't return #f, throw error.
7935 * ioext.c (fileno): renamed from %fileno.
7936 (soft-fileno): deleted.
7938 * ports.c (scm_port_revealed): don't need to check for -1 from
7940 (scm_set_port_revealed_x): return unspecified, not #f.
7942 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
7944 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
7946 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
7948 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
7950 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7952 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
7953 This is necessary on Ultrix, and doesn't hurt portability.
7955 * Makefile.in (dist-dir): New target, implementing a new dist system.
7956 (installed_h_files): Put in alphabetical order.
7957 Remove duplicate entries for markers.h and unif.h.
7958 (c_files): Remove duplicate entries for markers.c.
7959 (ancillary): Renamed from anillery; all uses changed. Remove
7960 PLUGIN; it's a directory, and needs special treatment in dist-dir.
7961 Remove all the ../doc/* files; doc/Makefile.in handles that.
7963 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
7965 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
7966 every if must have an else, or else the whole command has a
7967 non-zero exit code whenever the if's condition is false.
7969 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
7971 * posix.c: include string.h.
7973 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7975 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
7978 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
7979 Remove leading % from scheme names.
7980 Do not return error values, call SCM_SYSERROR or similar.
7982 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
7984 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
7986 * struct.c (scm_init_struct): new file.
7988 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
7990 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
7991 (scm_list_head): added list-head for rapidly chopping argument
7992 lists off of longer lists (and similar).

7996 * objprop.c (scm_object_property): assq the cdr of the whash
7997 handle for obj, not the handle itself.
7999 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8001 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8002 weak hash tables last of all marking to avoid an obscure gc bug.
8003 WARNING: circular lists stored in a weak hash table will hose us.
8005 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8007 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8008 new functions similar to scm_substring_move_left_x and
8009 scm_substring_move_right_x.
8011 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8013 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

8018 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8020 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8022 * strports.c (scm_strprint_obj): convenience function. C for
8023 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8025 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8026 removed to a separate library
8028 * init.c (scm_boot_guile): copied from guile-tcl.c.
8029 Initialization specific to tcl interpreters removed.
8031 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8033 * ports.c (scm_ports_prehistory): size malloced here doesn't
8034 matter so long as it is non-0 (got rid of "* 4").
8036 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8038 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8039 since its definition was bogus).
8041 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8043 * mallocs.[ch]: back again (for rx at least).
8045 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8047 * ports.c: removed functions relating to the mapping between ports
8048 and descriptors. (That stuff is unix-specific and should be collected
8049 in a separate library).
8051 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8052 (Tom Mckay@avanticorp.com)
8054 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8056 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8057 handled correctly (SCM_FREEP was applied to them) -- test for
8058 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8059 being overwritten with #f. (brown@grettir.bibliotech.com)
8061 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8063 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8066 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8068 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

8073 * list.c (scm_last_pair): map '()=>'()
8075 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

8078 Generalized assoc and hash-table functions.
8079 Factored pairs.c into multiple files.
8081 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8083 * gscm.c (gscm_run_scm): got rid of objprop.
8085 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8087 * genio.c (scm_getc):
8088 NOTE: fgetc may not be interruptable.
8090 * procprop.c (scm_stand_in_scm_proc):
8091 NOTE: don't use a alist here.
8092 (scm_set_procedure_properties_x): fix type checking throughout this file.
8094 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8096 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8097 after freeing part of the port table.

8101 * strports.c (scm_mkstrport):
8102 * vports.c (scm_make_soft_port): allocate a port table entry
8103 (possibly triggering gc) before setting the tag of the corresponding
8106 * pairs.c (scm_delq_x): never throw an error.
8108 * vectors.c (scm_make_vector): made the default vector fill argument
8109 into '() (much more useful than the previous value, "#unspecified")
8111 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8113 * ports.c (scm_add_to_port_table): Added fields
8114 to port table entries: file_name, line_num, col.
8115 Update these in open_file, gen_getc and gen_ungetc.
8116 Added procedures to access those fields.
8118 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8120 * procs.c (scm_make_subr_opt): new entry point for making
8123 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8125 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8127 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8129 * numbers.c (scm_exact_p): This function no longer
8130 implements "integer?".

8134 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8135 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8136 and the stats reporting formerlly built into repl.
8138 * repl.[ch]: removed.
8139 GC statistics keeping moved to gc.c.
8140 Other statistics keeping can be done from Scheme.
8141 REPLS are now written in Scheme.
8143 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8145 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

8148 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8150 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8152 * feature.c (scm_compiled_library_path): moved here from repl.c.
8153 This file is for stuff relating specifically to Scheme libraries
8156 * eval.c (scm_m_define): don't give warning about redefinition, don't
8159 NOTE: this should throw a resumable exception with parameters --
8160 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8162 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8164 * error.c: scm_warn eliminated.

8176 between the call to procedurep and use.
8178 * error.c (scm_everr):
8180 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8183 * strports.c: don't reveal the port's string to the caller
8184 because it changes size.
8186 (stputc stwrite): check/change the strings length with interrupts
8189 * objprop.c (scm_set_object_property_x &c): use the generic
8190 hashing functions and be threadsafe.
8192 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8193 (per suggestion jaffer@gnu.ai.mit.edu).
8195 * mbstrings.c (scm_multi_byte_string): guard against argument list
8198 * strings.c (scm_make_string): loop cleanup
8200 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8203 * weaks.c (scm_weak_vector): guard against argument list
8206 * variable.c (scm_builtin_variable): check for/make a built-in
8209 * vectors.c (scm_vector): while filling the new array,
8210 guard against a list of fill elements that grows after
8211 the vector is allocated.
8213 * hashtab.c -- new file: general hash table
8214 functions. hash, hashq, hashv, hashx.
8216 * tags.h: made wvect an option bit of vector.
8218 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
8220 * symbols.c: made the basic symbol table operations atomic.
8222 * root.c &c.: collected stack-specific global state.
8223 linum/colnum etc *should* be port-specific state.
8225 * struct.c (scm_init_struct): init the first struct type during
8226 initialization to fix a race condition.
8228 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8229 object, not in a global.
8230 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8232 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8233 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8235 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8236 and C symbols to begin with SCM_ or scm_.

8240 * gsubr.c (scm_gsubr_apply): statically allocate the
8241 array of arguments (bothner@cygnus.com).
8243 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>

8247 * async.c: New support for interrupt handlers.
8249 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8251 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8252 set the multi_byte flag correctly in symbols. This is wrong.
8253 intern_obbary_soft and msymbolize should take an extra parameter.
8254 Also, weird multibyte symbols don't print correctly.
8255 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8258 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8260 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
8261 use the system symhash. == #t means create an uninterned symbol.
8263 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8265 * strings.c (scm_make_shared_substring): build'em.
8266 It might better to keep a table of these and use one
8267 less cons-pair per shared-substring.
8269 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
8271 * strings.c (scm_string_shared_substring): create shared
