15 scm_set_ptob_XXX --> scm_set_port_XXX.
17 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
19 * ports.c, ports.h (scm_make_port_type): New interface for
20 creation of port types (replaces scm_newptob). Just as for the
21 smobs, we need to separate the internal representation of smob
22 types from the interface, so that we easily can add new fields and
23 rearrange things without caring about backward compatibility.
24 This change was forced by the need in GOOPS to create classes
25 representing port types.
26 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
27 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

36 (void_port_ptob, print_void_port, close_void_port, noop0):
37 Removed. Removed #include "genio.h" Added #include "objects.h",
40 * fports.c (prinfport): Moved code from ports.c.
42 (scm_fptob): Removed. Instead use new interface.
43 (scm_make_fptob): Added. (Need to create basic ports in a
44 specific order in ports.c.)

81 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
82 SCM_INOUT_PCLASS_INDEX): Added.
85 * Makefile.am: Removed genio.c, genio.x.
89 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
91 * init.c: Make sure that scm_post_boot_init_modules is called only
92 once. (Important when using a dumped image.; Thanks to Bernard
95 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
97 * guardians.c (scm_guardian_zombify): Separate scanning for
98 zombies from marking the pairs of the free list.
100 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
101 use the macros. (Thanks to Michael Livshin.)

104 lambda. Let your sins be purified by the blood of the lambda.
105 (Thanks to Eric Hanchrow.)

115 * stime.c (ftime): Delete declaration for this function --- let
116 the system supply it.
118 Cleanups from John Bley.
120 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
122 * gsubr.c: Don't include "gsubr.h" twice.
124 Cleanups for compilation on Irix 6, from David Kaelbling.
126 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
127 regex_t pointer. This is what the callers have, mostly.
128 (scm_regexp_exec): Don't forget to pass the `rx' argument to
129 scm_regexp_error_msg.
131 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
132 int. That way, if we get a warning on this line, it's more likely
133 that we're really missing bits we care about.
135 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
138 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
139 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
140 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
141 cast at all is more appropriate in every case. At the moment, we
142 assume everywhere that SCM is an integral type anyway.

153 fports.c (fport_fill_buffer): implement the interface change.
155 * ports.c (scm_fill_buffer): interface change: no longer increments
156 read_pos past the character that's returned. it seems clearer to
157 leave it to the caller to decide what to do (thanks Jim).
159 * vports.c (sf_fill_buffer): put the read char into the buffer
160 as well as returning it.
162 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

176 * ports.c (scm_ftruncate): throw error if offset works out negative.
178 * strports.c (st_flush): increase string size in blocks of
179 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
180 it's greater and reset read_buf_size.

182 to be maintained for output ports too (it holds the written
183 part of the string, while write_buf may have unwritten buffer
185 (st_truncate): rewritten.
186 (top of file): added a few notes.
188 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
190 Patch from Greg Badros:
191 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
192 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
193 (function pointer) argument to scm_make_gsubr and scm_make_subr
194 calls. This avoids warnings in C++ programs using guile-snarf.
196 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
198 * strports.c (st_grow_port): set pt->read_pos. set
199 pt->read_buf_size one less than pt->write_buf_size if there's
200 an unwritten char at the end of the string. similarly for
202 (st_resize_port): renamed from st_grow_port.
203 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
204 seek from read_end instead of write_end for SEEK_END.

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

322 * struct.c, struct.h:
324 In order to support different kinds of deallocation, a destructor
325 slot has been added to struct vtables. This allows for structs

465 * fports.c (local_seek): Signal an error if the seek fails.
466 * ports.c (scm_lseek): Don't check return value of port's seek

484 it shows up as terrible performance, as we GC constantly.
486 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
487 newline. A bit faster, and definitely hairier.

532 strports.c (scm_call_with_output_string): start with an empty
533 string, so seek and ftruncate can be used.
535 gdbint.c: adjust string port usage.
537 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
539 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
540 equivalent to fflush for the read buffer.

544 strport.c (st_read_flush): likewise.
545 vport.c (sf_read_flush): likewise.
546 fports.h (struct scm_fport): remove random member. there's nothing
547 left but fdes. leaving it as a struct to allow for future changes.
548 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
549 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
550 ptob proc if the read buffer is filled.
552 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
554 * ports.h (scm_port): add a rw_random member and replace
555 reading and writing members with rw_active member.
556 SCM_PORT_READ/SCM_PORT_WRITE: new values.
558 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
560 * ports.h (struct scm_port_table): add writing and reading members
561 to replace write_needs_seek: it isn't good enough for non-fports.
562 ports.c, ioext.c, fports.c: corresponding changes.
563 (struct scm_port_table): give it a typedef and rename to scm_port.
564 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
565 corresponding changes.
567 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
569 * ports.c (scm_newptob): bugfix: set seek member.
570 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
571 and generalised to all port types.
573 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
575 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
576 signals (it was only being done for handlers installed from Scheme).
577 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
578 waiting for input caused an EINTR error from read.
580 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
582 * ports.h (struct scm_port_table): make all the char members
583 unsigned, so they convert to int without becoming negative if large.
585 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
587 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
588 with threads enabled. rename this procedure to
589 fport_wait_for_input and take a port instead of a fdes.
590 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
592 * readline.c (scm_readline): Applied a patch from Greg Harvey to
593 get readline support working again: use fdopen to get FILE objects.
595 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
597 * gc.c (scm_init_storage): install an atexit proc to flush the
599 (cleanup): the new proc. it sets a global variable which can be
600 checked by the ptob flush procs to avoid trying to throw
601 exceptions during exit. not very pleasant but it seems more reliable.
602 * fports.c (local_fflush): check terminating variable and if set
603 don't throw exception.
604 * CHECKME: that the atexit proc is installed if unexec used.
606 * throw.c (scm_handle_by_message): don't flush all ports here.
607 it still causes bus errors.
609 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
612 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
614 * ports.c (scm_char_ready_p): check the port buffer and call the
615 ptob entry if needed.
617 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
618 ptob initialisers. use it in char-ready
620 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
622 * vports.c (sfflush): modified to write a char (since softports
623 currently use shortbuf.)
625 * fports.c (scm_standard_stream_to_port): moved to init.c and
628 * init.c (scm_init_standard_ports): make stdout and stderr
629 unbuffered if connected to a terminal. with stdio they
630 were line-buffered by default.
632 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
635 * ports.h (scm_ptobfuns): change fflush return to void.
636 change flush proc definitions.
638 * strports.c (scm_call_with_output_string): get size from
639 buffer instead of port stream.
640 (st_flush): new proc.
642 * ports.h (struct scm_port_table): added write_end member,
643 as an optimisation. set it where write_buf_size is set.
645 * ports.h (struct scm_port_table): change stream from void *
646 back to SCM. SCM presumably must be large enough to hold a
647 pointer (and probably vice versa but who knows.)
648 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
650 (scm_puts): rewritten
651 * fports.c (local_ffwrite, local_fputs): removed.
652 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

663 * ports.h (scm_ptobfuns): add seek function pointer.
664 * fports.c: set it to local_seek, new procedure.
667 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
668 use ptob for seek. take ptob instead of fport arg.
670 * ports.h (struct scm_port_table): new member write_needs_seek,
671 replaces reading member in fport struct.
673 * vports.c (sfgetc): store the getted char into the buffer.
674 rename to sf_fill_buffer and install it for fill-buffer in ptob.
675 the Scheme interface is still a procedure that gets a char.
676 (scm_make_soft_port): set up the port buffer (shortbuf).
678 * fports.c (local_fgetc, local_fgets): deleted.
679 * strports.c (stgetc): likewise.
680 * ports.c: scm_generic_fgets: likewise.
682 * ports.h (scm_ptobfuns): add fill_buffer.
683 * ports.c (scm_newptob): assign it.

685 put just the string into the stream, not cons (pos stream).
686 (stfill_buffer): new proc.
688 * ports.h: fport buffer moved into port table: to be
689 used for all port types.

735 * ports.h (SCM_SSTREAM): new macro.
737 * fports.c (scm_input_waiting_p): use scm_return_first, since port

888 * strop.c (scm_substring_move_x): New function, which can handle
889 arbitrary overlapping substrings.

1020 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1022 Most of this batch of changes is about how to deal with extended
1023 types when an object system is loaded into Guile. A nice object
1024 system is capable of representing Guile's types as class objects.
1026 For example, we want a regular expression to be of class <regex>.
1027 But regular expressions are smobs which aren't under direct
1028 control of the object system, so there has to be some mechanism
1029 which informs the object system that a new class should be created
1030 which can represent the smob type. I call this a "wrapper class".
1032 * objects.c: #include "smob.h";
1033 (scm_class_keyword): Removed. (Class is automatically created by
1035 (scm_smob_class): Array of smob classes indexed by smobnum.
1036 (scm_make_extended_class): "Plugin" function pointer for creation
1037 of wrapper classes for smob and struct types.
1038 (scm_class_of): Handle compiled closures. (Currently regarded as
1040 Use scm_smob_class to handle smob types;
1041 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1042 through scm_smob_class;
1045 * smob.c (scm_newsmob): Also create a wrapper class if
1046 scm_smob_class has been initialized.
1048 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1049 type code and smobnum.
1051 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1052 (scm_struct_table): Weak key table with auxilliary information for
1053 struct types. Currently used for names and wrapper classes.
1054 (scm_struct_ihashq): Hash function for structs.
1055 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1056 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1057 for accessing names of vtables. The record implementation in
1058 boot-9.scm currently uses the setter to record the name of record
1059 types. When the object system is initialized, it can use this
1060 information to create wrapper classes with suitable names.
1061 (scm_init_struct): Allocate scm_struct_table.
1062 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.

1076 (scm_hash_fold): New procedure. Used to process all entries in a
1077 hash table (in no particular order).
1079 Argh! For the umpteenth time I got compilation errors because of
1080 the "intuitive" name `kw'. This has to have an end:
1082 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1083 "kw" --> "keywords" everywhere.
1084 (I doubt that this will cause big compatibility problems since the
1085 application interface is unaffected.)
1087 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.

1236 SYMB now point to const.
1238 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1240 * print.c (scm_iprin1): Use scm_procedure_name instead of
1241 scm_procedure_property for compiled closures.
1243 * tags.h (scm_tc7_pws): New procedure type. Four representations
1244 for procedure-with-setters were considered before selecting this
1247 1. A closure where the CODE and ENV slots are used to represent
1248 the getter and a new SETTER slot is used for the setter. The
1249 original getter is stored as a `getter' procedure property. For
1250 closure getters, the CODE and ENV slots contains a copy of the
1251 getter's CODE and ENV slots. For subr getters, the CODE contains
1254 2. A compiled closure with a call to the getter in the cclo
1255 procedure. The getter and setter are stored in slots 1 and 2.
1257 3. An entity (i.e. a struct with an associated procedure) with a
1258 call to the getter in the entity procedure and the setter stored
1259 in slot 0. The original getter is stored in slot 1.
1261 4. A new primitive procedure type supported in the evaluator. The
1262 getter and setter are stored in a GETTER and SETTER slot. A call
1263 to this procedure type results in a retrieval of the getter and a
1264 jump back to the correct eval dispatcher.
1266 Representation 4 was selected because of efficiency and
1269 Rep 1 has the advantage that there is zero penalty for closure
1270 getters, but primitive getters will get considerable overhead
1271 because the procedure-with-getter will be a closure which calls
1274 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1275 <procedure-with-setter>, but together with rep 2 it suffers from a
1276 three level dispatch for non-GOOPS getters:
1278 cclo/struct --> dispatch proc --> getter
1280 This is because the dispatch procedure must take an extra initial
1281 argument (cclo for rep 2, struct for rep 3).
1283 Rep 4 has the single disadvantage that it uses up one tc7 type
1284 code, but the plan for uniform vectors will very likely free tc7
1285 codes, so this is probably no big problem. Also note that the
1286 GETTER and SETTER slots can live directly on the heap, using the
1287 new four-word cells.
1289 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1290 SCM_SETTER): New macros.

1374 understand, when I ran automake in the top level directory. This
1375 may be contamination by Cygnus internal releases. If you re-run
1376 automake and this change gets reverted, don't worry about it.

1536 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1537 scm_logbit_p): Do the computation in ulongs. This is not as nice
1538 as doing it in bignums, but at least it's good enough for
1539 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1541 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1542 subexpressions. (Thanks to Charbel Jacquin.)

1554 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1556 * modules.c, modules.h: New files: C interface to modules. (This
1557 is necessary in order to interface the object system to Guile
1558 properly. The guts of these modules will be replaced by the new
1559 module system in the future.)
1561 * init.c: Added #include "modules.h"
1562 (scm_boot_guile_1): Call scm_init_modules.
1563 (invoke_main_func): Call scm_post_boot_init_modules.
1565 * Makefile.am: Added modules.c, modules.x, modules.h.
1567 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1569 * procs.c: #include "objects.h"
1570 (scm_procedure_p): Return #t also on structs which are operators.
1572 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1573 <operator-metaclass> and <entity-class> to <standard-class>,
1574 <operator-class> and <entity> in order to conform with STKlos
1577 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1578 which isn't an operator.
1579 (SCM_APPLY): Ditto, but jump to badproc.
1581 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1583 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1584 Previously, structs implanted in code were interpreted as forms
1585 the operator of which was a gloc. We solve this by checking for
1586 the zero in the emulated vcell in the struct vtable. Since
1587 implanted structs always will look like forms with a gloc
1588 operator, execution will only be slowed down by maximally one
1589 extra test-and-branch per application.
1591 * evalext.c (scm_definedp): Removed check for isyms; Added a
1592 second optional argument: It is now possible to supply an
1593 evaluation environment in which to look for the symbol.
1595 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1597 * readline.c (scm_init_readline): Set
1598 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1600 * coop.c (coop_condition_variable_wait): Removed
1601 (coop_condition_variable_wait_mutex): Folded logic of
1602 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1603 prevent condvar signal lossage. Previously, another thread could
1604 start to run after unlocking the mutex but before putting the
1605 current thread on the wait queue. If that thread then would
1606 signal the first, the signal would be lost. (Thanks to Christian
1609 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1611 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1614 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1616 * objects.c (scm_i_make_class_object): Renamed from
1617 make_class_object; exported; error checking moved to
1618 scm_make_class_object and scm_make_subclass_object.
1619 (scm_make_class_object, scm_make_subclass_object): Use
1620 scm_i_make_class_object.
1621 (scm_make_subclass_object): Let the subclass have same metaclass
1624 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1626 * debug.c (scm_debug_options): Bugfix: Set the value of
1627 scm_stack_checking_enabled_p after setting debug options;
1628 #include "stackchk.h". (Thanks to Richard Polton.)
1630 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1632 * unif.c (scm_array_contents): removed unnecessary test for 0
1635 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1637 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1638 Replaced by macro `collect' in boot-9.scm.
1640 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1642 * eval.c (scm_copy_tree): Copy source properties if existent.
1644 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1645 don't, we may end up passing memoized source to a transformer.)
1647 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1649 * stack.c (get_applybody): Help function which lookups the first
1650 body form of the apply closure.
1651 (read_frames): Prevent the source of the first form of the apply
1652 closure from being recorded. This would only be confusing.
1654 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1655 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1657 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1659 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1661 (read_frames): Use SCM_MACROEXPP.
1663 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1665 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1666 don't contain interesting information since all arguments are
1667 present in the frame which applies the compiled closure anyway.);
1668 Skip the transformer application frames.
1670 * print.c (scm_iprin1): Print gsubrs as primitives.
1672 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1674 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1676 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1677 that we can identify these in a backtrace. (This change doesn't
1678 introduce any significant speed penalty.)
1680 * eval.c: Added note about `serial-map' using scm_map.
1682 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1683 readline options. They should reside in their own options array.
1685 * readline.c, readline.h (scm_readline_options,
1686 scm_readline_opts): Moved readline options here.
1688 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1690 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1691 SCM_ROCHARS instead of SCM_CHARS.
1693 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1694 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1696 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1698 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1699 This is quite important since the latter clears the
1700 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1701 every single character read...
1703 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1705 * print.c (scm_iprin1): Removed suspect looking (and indeed
1706 malevolent) semicolon after test for user supplied closure print
1707 procedure. (Thanks to Telford Tendys.)
1709 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1710 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1711 starting to search the list. Removed call to sloppy_mem_check.
1713 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1714 procedures: Same as scm_delq_x et al, but delete maximally one
1717 * options.c (scm_options, scm_init_options): GC-protect option
1718 values of type SCM. (Thanks to Telford Tendys.)
1720 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1722 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1723 make sure that there always is a "real" scm_lookupcar.
1725 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1727 * read.c, read.h (scm_read_opts): New read options
1728 "history-length" and "history-file".
1729 (scm_read_options): Stifle history to history length.
1731 * readline.c (scm_read_history, scm_write_history): New procedures.
1733 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1735 * eval.h (scm_macro_eval_x): Removed declaration.
1737 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1738 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1739 Renamed and made global.
1741 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1742 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1744 * evalext.c, evalext.h: New files. Contain non-R5RS things
1745 having to do with evaluation.
1747 * evalext.c (scm_serial_map): New procedure: Version of `map'
1748 which guarantees that the procedure is applied to the lists in
1750 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1751 returns a list of the results of the body forms instead of the
1752 result of the last body form.
1753 (scm_definedp, scm_m_undefine): Moved from eval.c
1755 * evalext.h (scm_m_sequence_to_list): Added declaration.
1757 * macros.c, macros.h: New files.
1758 (scm_procedure_to_syntax, scm_procedure_to_macro,
1759 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1760 scm_macro_name, scm_macro_transformer): Moved from eval.c
1761 (scm_make_synt): Moved from eval.c
1763 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1765 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1768 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1770 * debug.c, print.c: Added #include "macros.h".
1772 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1774 This change adds the ability to use `unread-char' multiple times
1775 without interspersed reads and adds the new procedure
1776 `unread-string'. The change is optimized for the common case of
1777 unreading a single character. This is also the reason behind the
1778 choice to store characters in the port itself: in most cases no
1779 extra malloc is required.
1781 The amount of code in some macros in ports.h has been increased to
1782 the extent that they would fit better as C functions, but, since
1783 this code belongs to the port representation, such functions
1784 should be placed in ports.c which would cause calls back and forth
1785 between ports.c and genio.c. That is not good for performance.
1786 Also, keeping them as macros allows the compiler to do some
1787 optimizations which are needed to make the current interface
1788 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1790 One benchmark (Guile startup time) indicates an increase of
1791 loading speed of 1%. Another (reading (using `read') boot-9.scm
1792 10 times) shows no change in performance.
1794 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1795 made to find a beautiful solution.)
1797 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1798 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1799 character. (SCM_CLRDY clears all.)
1800 (SCM_N_READY_CHARS): New macro: Returns number of unread
1801 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1802 (struct scm_port_table): New fields: `entry' contains port table
1803 index, `cp' points to last unread char, `cbuf' is the buffer for
1804 unread chars, `cbufend' points after end of the character buffer.
1806 * ports.h, ports.c (scm_unread_string): New procedure.
1807 (scm_grow_port_cbuf): New function.
1809 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1811 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1812 to read unread characters. Use SCM_TRY_CLRDY instead of
1815 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1817 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1819 * genio.c, genio.h (scm_ungets): New function.
1821 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1824 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1826 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1827 declarations. (Thanks to Russ McManus.)
1829 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1831 * numbers.c (num2long): As a software archeologist, I'm proud of
1832 this finding! :) Preliminary dating suggests an almost 4 year old
1833 remnant from the SCM ancestor. The sample has been removed from
1834 the finding site and is now safely stored in the repository.
1836 * numbers.h: Removed prototype for num2long.
1838 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1840 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1841 array as second arg.
1842 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1843 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1844 * gh.h: Updated and added prototypes.
1846 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1848 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1850 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1852 * guile-snarf.in: Never generate an empty file. (Thanks to
1855 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1856 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1857 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1858 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1859 gh_new_procedure5_0): Specify argument types, to appease C++
1860 compilers. (Thanks to Brad Bowman.)
1862 Bug reports from Russ McManus:
1863 * guile-snarf.in: If the CPP environment variable is set, use that
1864 as the C preprocessor, instead of the preprocessor autoconf
1866 * snarf.h (SCM_PROC): Cast the function pointer passed to
1867 scm_make_gsubr, to satisfy C++.
1869 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
1870 Use the handler passed, instead of ignoring it and using
1871 gh_standard_handler. (Thanks to Etienne Bernard.)
1873 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
1875 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
1878 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
1880 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

1895 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
1898 * script.c (scm_compile_shell_switches): Define
1899 use-emacs-interface in the root module, so the repl code can see
1900 it. See today's change to top-repl in ice-9/boot-9.scm.
1902 * filesys.c (set_element, get_element): Make sure that `element'
1903 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
1904 Boekemeier and Jorgen "forcer" Schaefer.)
1906 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
1908 * chars.c (scm_charnames): In ASCII character name table, make
1909 newlines print as #\newline by default, not #\nl.
1911 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
1912 alphabetical order. Oh thrills. But it helps me know how far
1913 along in the compilation I am.
1914 * Makefile.in: Regenerated.
1916 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1918 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
1919 #bytes(...) to #y(...), and syntax for short vectors from
1920 #short(...) to #h(...). This may seem nutty, but, like the other
1921 uniform vectors, byte vectors and short vectors want to have the
1922 same print and read syntax (and, more basic, want to have read
1923 syntax!). Changing the read syntax to use multiple characters
1924 after the hash sign breaks with the conventions used in R5RS and
1925 the conventions used for the other uniform vectors. It also
1926 introduces complexity in the current reader, both on the C and
1927 Scheme levels. (The Right solution is probably to change the
1928 syntax and prototypes for uniform vectors entirely.)
1930 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
1932 Don't use local_fgets on sockets; ftell doesn't work on sockets.
1933 (Thanks to Jorgen "forcer" Schaefer.)
1934 * ports.h (SCM_NOFTELL): New flag.
1935 * fports.c (local_fgets): If it's set, use the generic fgets.
1936 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
1938 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1940 * script.c (scm_compile_shell_switches): Add handling of -q switch
1941 (inhibit loading of user init file).
1942 (scm_shell_usage): Add usage text for -q switch.
1943 (scm_compile_shell_switches): Always load user init file first if
1944 it is loaded at all.
1946 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
1948 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
1949 and is now broken under NetBSD. I can't fathom what it's trying
1950 to do, so I've replaced it with something that I do understand,
1951 which seems to work, and which isn't broken on NetBSD. "Progress?
1952 You Decide." (Thanks to Perry Metzger.)
1954 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
1955 signed/unsigned comparison.
1957 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
1959 Warning fixes from Greg Harvey:
1960 * unif.c (scm_array_set_x): initializer for pos
1961 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
1962 * struct.c (scm_struct_ref, scm_struct_set_x): Added
1963 initializers for field_type, since EGCS so desparately wants to
1965 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
1966 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
1967 when GUILE_DEBUG is defined.
1968 * dynwind.h (scm_wind_chain): Same.
1969 * ports.h (scm_pt_size, scm_pt_member): Same.
1970 * print.h (scm_current_pstate): Same.
1971 * procs.h (scm_make_cclo): Same.
1973 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
1975 Handle short and long long uniform arrays properly. (Thanks to
1977 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
1978 raeql_1): Add cases for scm_tc7_svect (short vectors) and
1979 scm_tc7_llvect (long long vectors).
1981 Change the way libguile and boot-9.scm are timestamped, to try to
1982 get rid of these spurious mismatch warnings. Now both
1983 libguile/versiondat.h and ice-9/version.scm are generated directly
1984 by the configuration process, rather than having version.scm
1985 generated directly, and libguile/versiondat.h generated by the
1986 Makefile, which is generated by configure. It seems that
1987 sometimes the Makefile would change, but versiondat.h depends on
1988 Makefile.in, not Makefile, so it wouldn't get rebuilt.
1989 * Makefile.am (versiondat.h): Target removed; this is generated
1990 directly by the configure script now.
1991 (BUILT_SOURCES): Remove versiondat.h.
1992 * versiondat.h.in: New file, transformed by the configure script
1994 * Makefile.in: Regenerated.
1996 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
1997 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
1998 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
1999 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2000 if we want to use them in a header file some day, we can. (Thanks
2001 to Michael Livshin.)
2003 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2004 SCM numbers, so we won't have rollover problems; the range of a
2005 signed long in milliseconds is about 25 days. (Thanks to Karl
2008 Don't redefine sleep and usleep; fix this problem now.
2009 * coop.c (sleep, usleep): Remove declarations; we don't use or
2010 redefine these any more.
2011 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2012 job of usleep and sleep in a thread-friendly way. We can use
2013 these in the rest of Guile. Define versions for systems both with
2014 and without iselect.
2015 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2016 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2017 we're just using it, not redefining it, we can use a K&R style
2019 (sleep): Declare this, too, if the system hasn't.
2020 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2021 scm_uthread_sleep if they're available; otherwise, just call the
2023 * scmconfig.h.in: Regenerated.
2025 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2027 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2029 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2031 * threads.c: Doc fix.
2033 The argument type of usleep varies from system to system,
2034 as does the return type. We really shouldn't be redefining usleep
2035 at all, but I don't have time to clean that up before the 1.3.
2036 release. It's on the schedule for afterwards. (Thanks to Julian
2038 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2040 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2041 * scmconfig.h: Regenerated.
2043 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2044 right way to handle system variation. Autoconf's approach is the
2046 * simpos.h (scm_software_type): Declaration deleted.
2048 * script.c (scm_find_executable): Don't test if unix is #defined
2049 here; first, NetBSD doesn't #define it, and second, it's the wrong
2050 way to go about these things. (Thanks to Perry Metzger.)
2051 (dld_find_executable): Delete this MSDOS support code. This isn't
2052 the way we want to support this; it needs to be rethunk at a
2055 * genio.c (scm_do_read_line): Don't just politely check that the
2056 line was either non-empty or EOF. Abort if it's empty and not
2059 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2061 * scmconfig.h.in: Regenerated.
2063 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2066 * genio.c (scm_do_read_line): Count lines correctly when the file
2067 doesn't end in a newline.
2069 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2071 * genio.c (scm_do_read_line): Maintain the line count correctly.
2072 (Thanks to Harvey J. Stein and Greg Harvey.)
2074 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2077 * numbers.c (big2str): Protect t from garbage collection until
2078 we're done. (Thanks to Gary Houston.)
2080 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2082 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2084 * Makefile.in: Regenerated.
2086 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2087 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2090 Do magic to mix reads and writes on stdio FILE-based ports.
2091 (Thanks to Christian Lynbech.)
2092 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2094 (pre_read, pre_write): New functions.
2095 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2096 local_fputs): Call them.
2097 (local_fflush): Mark the port as ready for reading and writing.
2098 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2099 flags on new port objects. This might not be accurate --- who
2100 knows what state the FILE * is in when we get it --- but it won't
2101 do extraneous calls to fflush or fseek, so it's no worse than the
2102 behavior before this change.
2103 * ports.h: Add comment.
2105 Centralize the creation of port objects based on stdio FILE * in
2106 fports.c; don't just throw them together anywhere.
2107 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2108 what the rest of Guile wants. Don't set the revealed count;
2109 that's only appropriate for stdin, stdout, stderr.
2110 (scm_standard_stream_to_port): This function does set the revealed
2112 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2113 not scm_stdio_to_port.
2114 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2115 * fports.c (scm_open_file): Same.
2116 * posix.c (scm_pipe): Same.
2117 * socket.c (scm_sock_fd_to_port): Same.
2118 * ioext.c (scm_fdopen): Same.
2119 (scm_freopen): Moved from here to...
2120 * fports.c (scm_freopen): ... here. This is really something that
2121 munges the internals of an fport, so it should go here.
2122 * fports.h (scm_stdio_to_port): Adjust prototype.
2123 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2124 * ioext.h (scm_freopen): Prototype removed.
2126 * filesys.c (set_element, get_element): This can work on both pipe
2127 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2130 * scmconfig.h.in: Regenerated.
2132 Change the definition of the functions in scm_ptobfuns so that
2133 they get passed the port object, not the port's stream.
2134 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2135 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2136 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2137 Pass the port itself to the scm_ptobs function.
2138 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2139 scm_generic_fgets): Same.
2140 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2141 getc_void_port, fgets_void_port, close_void_port): Just change the
2142 argument names; these functions don't really do anything.
2143 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2144 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2145 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2146 Also, use prototyped definitions, and get rid of the extra
2148 (scm_fptob, scm_pipob): We don't need casts here any more.
2149 * strports.c (prinstpt): Use prototype declarations.
2150 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2151 and use SCM_STREAM to get the string info. Also, use prototyped
2152 definitions, and get rid of the extra declarations.
2153 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2156 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2157 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2159 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2160 scm_fgets, for consistency.
2161 (scm_fptop, scm_pipob): References updated.
2163 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2165 Include the source location in error messages for scripts.
2166 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2167 stack is still there when we catch the error.
2168 * throw.c (handler_message): If we are handling an error with a
2169 message, then put together the proper arguments and call
2170 scm_display_error, instead of scm_display_error_message. That
2171 displays source location, if it can find it.
2173 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2175 * gc.c (scm_unprotect_object): Change this so that calls to
2176 scm_protect_object and scm_unprotect_object nest properly.
2177 (scm_protect_object): Doc fixes.
2179 * strings.c (scm_string_set_x): Require the argument to be a
2180 writable string, not a substring or a symbol.
2181 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2182 (Thanks to John Redford and Charbel Jacquin.)
2184 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2186 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2188 * eval.c (safe_setjmp): Remove this misunderstanding.
2189 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2192 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2194 * libguile.h: Mark these as C declarations, for compilation by C++
2197 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2198 __cplusplus clause. I seriously doubt this ever worked the way
2199 the author seems to have intended.
2201 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2203 Utterly needless cleanups to hopelessly messy code.
2204 * ports.c: Doc fixes.
2205 (scm_fflush): Moved to ...
2206 * genio.c (scm_fflush): ... here, amongst all the other port
2207 method invocation functions.
2208 * genio.h, ports.h: The prototype moves too.
2210 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2212 * backtrace.c (display_error_body): The current frame does not
2213 always have a parent frame; consider a function called directly
2214 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2217 * alloca.c (alloca): Undo yesterday's changes, and simply call
2218 malloc directly for storage, and abort if we don't get what we
2219 want. The situation is much simpler --- just call malloc. Emacs
2220 has bizarre/evil requirements (signal handlers might malloc unless
2221 you set this global flag, so you have to set the flag around all
2222 calls to malloc) which we are certainly not going to conform to,
2223 so we can do the simple and obvious thing.
2225 * coop.c (coop_condition_variable_wait): Make this function
2226 static. It's only useful internally --- you should never just
2227 wait on a condition variable.
2228 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2230 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2232 * unif.c (scm_array_set_x): Accept any kind of number as an
2233 element for a uniform vector of doubles. This is more consistent
2234 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2236 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2237 works; I can't conveniently test it myself. (Thanks to Dvid
2238 Tillman for the bug report.)
2240 * init.c: Doc fixes.
2242 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2243 from here, not from scm_compile_shell_switches (which is a pretty
2244 dumb place to do it).
2245 (scm_load_startup_files): New function.
2246 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2247 * script.c (scm_compile_shell_switches): Don't load the startup
2249 (scm_ice_9_already_loaded): Variable moved.
2250 * init.c (scm_load_startup_files): Prototype for new function.
2251 * gh_init.c (gh_enter): Doc fix.
2253 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2255 Some anti-warning changes from Greg Harvey.
2256 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2257 warnings when it doesn't understand our NORETURN declarations in
2259 * posix.c (scm_mknod): Similar.
2261 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2263 * posix.c (scm_getpwuid): If we can't find an entry, return our
2264 own message, instead of using scm_syserror --- the getpwMUMBLE
2265 functions don't set `errno' to anything interesting.
2267 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2269 Get rid of warnings from the cooperative threading system.
2270 * threads.h (scm_single_thread_p, scm_yield,
2271 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2272 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2273 scm_wait_condition_variable, scm_signal_condition_variable): Add
2274 prototypes for these Scheme-visible functions.
2275 * coop-defs.h (coop_next_runnable_thread,
2276 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2277 Prototypes for these here, even though they're from iselect.c.
2278 (coop_condition_variable_wait, coop_join): Add prototypes.
2279 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2280 scm_threads_free_condvar): Make these smob functions static.
2281 * coop-threads.h (coop_init): Give this a real prototype.
2282 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2283 (coop_next_runnable_thread): No need to provide prototype; it's in
2286 * scmconfig.h.in: .detarenegeR
2288 * iselect.c, threads.c: Doc fixes.
2290 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2292 * Makefile.in: Regenerated with a patched automake, to get
2293 dependency generation right when using EGCS.
2295 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2296 warning. (Thanks to Robert Pluim.)
2298 * inet_aton.c (inet_aton): Reassure the compiler that the
2299 arguments to the <ctype.h> macros are all unsigned characters, not
2302 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2304 Getting rid of more warnings...
2305 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2306 today's change to ../configure.in.
2307 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2308 * scmconfig.h.in: Regenertaded.de.,.__
2309 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2310 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2313 * readline.c: Doc fix.
2314 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2315 * readline.h (scm_filename_completion_function): Add prototype.
2316 (scm_init_readline): Make this into a prototype.
2318 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2319 declare this, instead of calling scm_make_subr manually.
2321 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2323 * readline.h (scm_init_readline): Add prototype for this.
2324 (scm_init_readline): Make this a real prototype.
2326 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2328 Warning fixes from Maciej Stachowiak:
2329 * backtrace.h (scm_display_application, scm_backtrace): Add
2331 * debug.c (scm_m_start_stack): Make this function static.
2332 * fluids.h (scm_fluid_p): Add prototype.
2333 * procprop.c (scm_i_procedure_arity): Make this function static.
2334 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2335 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2336 * root.h (scm_dynamic_root): Add external prototype.
2337 * scmsigs.h (scm_usleep): Add external prototype.
2338 * script.h (scm_init_script): Use prototype, not K&R decl.
2339 * stacks.h (scm_stack_id): Add external prototype.
2340 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2342 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2344 * gh.h: took out the definitions of vset and vref, since they are
2345 replaced by the proper vector routines that correspond to the R4RS
2348 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2350 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2351 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2352 third argument, a C expression that should result in a SCM value,
2353 which is used to initialize the variable. Reimplemented
2354 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2357 * version.h (scm_libguile_config_stamp): Add prototype.
2358 (From Maciej Stachowiak.)
2360 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2362 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2363 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2365 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2367 * print.c (scm_iprin1): Rather than having one i, and using it in
2368 several places, declare a fresh i local to each block where it is
2369 used, and give it a signedness appropriate to its use in each case.
2370 (scm_iprlist): Same.
2372 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2373 comparison warnings.
2375 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2376 signed/unsigned clashes.
2378 * posix.h (scm_tmpnam): Added prototype.
2380 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2381 scm_make_subclass_object): Add external prototypes.
2383 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2384 comparison is okay here.
2386 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2388 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2389 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2391 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2394 * load.c (swap_port): Make this function static.
2396 * load.c (scm_search_path): Make max_path_len and max_ext_len
2397 unsigned, since they're compared against string sizes.
2399 * load.c (init_build_info): Make i unsigned.
2401 * ioext.h (scm_read_line): Add prototype.
2403 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2404 scm_hash_fn_remove_x): Make hash bucket index local variable k
2405 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2406 accurately as possible.
2408 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2409 comparisons, and range checking to make sure those casts are
2412 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2413 signed/unsigned comparisons.
2415 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2416 avoid signed/unsigned comparisons.
2417 * smob.h (scm_numsmob): Change extern declaration to match.
2419 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2420 avoid signed/unsigned comparisons.
2421 * ports.h (scm_numptob): Change extern declaration to match.
2422 (scm_current_load_port, scm_set_port_line_x,
2423 scm_set_port_column_x): New prototypes.
2425 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2426 test code, and it causes warnings.
2428 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2429 gh_uniform_vector_ref): Added prototypes.
2431 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2432 debugging support unconditionally. That's backtrace.c, stack.c,
2433 debug.c, and srcprop.c.
2434 (EXTRA_libguile_la_SOURCES): Omit those from here.
2435 * Makefile.in: Regenerated.
2437 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2439 * options.c (scm_options): Bugfix: Allow empty list of options!
2441 * debug.c, debug.h (scm_single_step): Removed.
2442 (scm_with_traps): New procedure. This procedure could easily be
2443 written in Scheme but needs to be highly optimized.
2445 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2447 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2448 Check SCM_TRAPS_P before trapping.
2450 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2452 Changes to avoid signed/unsigned comparison warnings.
2453 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2454 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2455 so they can have appropriate types for each application. Make i
2456 signed. Use initializers in some spots. I'll probably pay for
2458 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2459 (scm_must_realloc): Make nm unsigned.
2460 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2461 (scm_init_storage): Use prototype-style definition, and make the
2463 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2464 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2466 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2467 avoid signed/unsigned comparison warnings, and because the return
2468 value of readlink may be -1. Don't bother casting the third
2469 argument to readlink.
2471 * filesys.c (scm_dirname, scm_basename): Move these to their own
2472 page, at the end of the file.
2473 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2475 * eval.h (scm_eval_options_interface): Add external prototype for this.
2476 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2478 * eval.c (scm_lookupcar1): Make this static.
2480 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2481 Make these prototype declarations, not K&R-style.
2483 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2484 unsigned comparison warning.
2486 * appinit.c: File removed. It had a single function in it, empty,
2487 whose reason for existence is explained in no documentation or
2488 comment. I think it's there as a default for some Tcl-style
2489 initialization, but Tcl abandoned that approach a while ago.
2490 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2491 (BUILT_SOURCES): Remove appinit.x.
2492 * Makefile.in: Regenerated.
2494 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2496 * Makefile.in: Regenerated using the last public version of
2497 automake, not the hacked Cygnus version.
2499 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2501 Remove Totoro kludge.
2502 * Makefile.in, scmconfig.h.in: Regenerated.
2503 * init.c, readline.c: Don't check if TOTORO is #defined.
2505 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2507 * Makefile.am: Adjust for new thread configuration system.
2508 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2509 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2511 (THREAD_LIBS): Definition deleted; automake will generate such
2512 things automatically.
2513 * Makefile.in: Regenerated.
2515 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2517 Simplify smob and port marking; set the mark bit in the generic
2518 marking code, and make marker routines only responsible for
2519 turning up outgoing pointers.
2520 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2521 before calling the marking function. Don't call the marking
2522 function if it's zero.
2523 * markers.c (scm_mark0): Just return #f. This function isn't
2524 necessary at all now, but it's harmless to call it. We'll leave
2525 it in so other folks' code doesn't croak at link time.
2526 (scm_markcdr): Don't call SCM_SETGC8MARK.
2527 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2528 * dynl.c (mark_dynl_obj): Same.
2529 * root.c (mark_root): Same.
2530 * srcprop.c (marksrcprops): Same.
2531 * unif.c (markra): Same.
2532 * variable.c (scm_markvar): Same.
2533 * ports.c (scm_markstream): Same.
2534 (void_port_ptob): Specify zero for our marking function.
2535 * debug.c (debugobjsmob): Same.
2536 * dynwind.c (guardsmob): Same.
2537 * filesys.c (dir_smob): Same.
2538 * fluids.c (fluid_smob): Same.
2539 * fports.c (scm_fptob, scm_pipob): Same.
2540 * mallocs.c (mallocsmob): Same.
2541 * regex-posix.c (regex_t_smob): Same.
2542 * smob.c (freecell, flob, bigob): Same.
2543 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2544 * throw.c (jbsmob, lazy_catch_funs): Same.
2546 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2548 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2549 scm_copy_tree on code in order not to let memoized code to leak
2550 out. Thus, scm_copy_tree needs to copy vectors as well since
2551 quasiquote can introduce evaluated code also inside vector
2554 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2556 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2558 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2559 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2562 * unif.c: Say that ivect and uvect are of type signed and unsigned
2563 long instead of int in commentary so that it correctly describes
2566 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2568 * stime.c: Removed declaration of strptime. (It should be
2569 declared by the system headers. If it turns out that some systems
2570 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2572 * stime.h: Renamed TIMEH --> STIMEH
2574 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2575 to increase portability, don't use structure assignment.
2576 (Thanks to Nicolas Neuss.)
2578 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2580 (finalize_fd_sets): Added empty statement after last case label.
2581 (Thanks to Nicolas Neuss.)
2583 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2586 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2588 * init.c, readline.c: OK, I won't have these readline.x bug
2589 reports anymore. We've had them since April. The current reason
2590 is a completely unintelligible failure of totoro.red-bean.com to
2591 do the test for rl_getc_function in libreadline correctly. This
2592 kludge overrides the test if we're on totoro so that the snapshot
2593 generation process can work.
2595 * readline.c: Define a strdup replacement if not existent on system.
2597 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2599 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2600 This change makes scm_make_vector R5RS compatible. We cannot keep
2601 the third argument since people want to be able to deduce the form
2602 of the C function call only by looking at R5RS. (At the same time
2603 we have removed some unnecessary complexity!)
2605 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2606 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2607 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2608 argument in call to scm_make_vector.
2610 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2612 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2613 This macro is useful in applications.
2615 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2617 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2618 (scm_parse_path, scm_search_path): New Scheme level procedures.
2620 * load.h (scm_internal_parse_path, scm_parse_path,
2621 scm_search_path): Declared.
2623 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2625 * filesys.c (dirname, basename): New procedures.
2627 * init.c (scm_boot_guile_1): Removed condition around
2630 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2631 new data type (guards) for representation of C level guards and
2632 data on the wind chain.
2633 (scm_internal_dynamic_wind): New function.
2635 * dynwind.h: Declare scm_internal_dynamic_wind.
2637 * root.h (scm_root_state): Added scm_cur_loadp.
2639 * root.c (mark_root): Added comment about cur_loadp.
2641 * load.c: #include "dynwind.h";
2642 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2645 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2647 * ports.c (current-load-port): New procedure.
2649 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2651 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2652 not a tty, return #f.
2654 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2655 to Julian Satchell and Roland Kaufmann.)
2657 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2658 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2660 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2662 * debug.h, debug.c (scm_start_stack): New function. Implements
2663 the guts of old scm_m_start_stack.
2665 * debug.c (scm_m_start_stack): Use scm_start_stack.
2667 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2668 start_stack and restart_stack. (These have static scope.)
2670 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2672 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2673 readline functions to come in release 2.3. (Thanks to Chet
2675 (handle_errors): Use the above functions.
2677 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2679 * readline.c: Improvements for readline support: Handle errors
2680 better; Implement before-read-hook.
2682 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2684 * init.c (scm_boot_guile_1), readline.c: Test for
2685 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2686 assure that we have version >= 2.1.)
2688 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2690 * readline.c (scm_readline): Defer interrupts while we're calling
2693 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2694 away the string to add_history.
2695 (completion_function): Do completion for readline. (Thanks to
2697 (scm_filename_completion_function): New procedure: Filename
2699 (current_input_getc): New function. Use this one instead of
2700 standard getc from readline.
2702 * throw.c, throw.h (scm_handle_by_throw): New function: This
2703 handler throws errors to next handler on the dynwind chain.
2705 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2707 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2710 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2712 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2714 (scm_procedure_properties): Modified to return arity together with
2716 (scm_procedure_property): Added the read-only property `arity'.
2717 (scm_set_procedure_property_x): It is an error to set the `arity'
2720 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2721 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2723 * procprop.h (scm_sym_arity): New symbol.
2725 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2726 to set the dispatch procedure of an operator or entity object.
2728 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2729 Made procedure slots read-only.
2731 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2732 scm_tcs_cons_gloc case in zero args switch; Fixed args
2733 construction for operators in scm_tcs_cons_gloc case in two args
2736 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2738 * fluids.c: Removed use of assert.h (in order to avoid
2741 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2743 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2745 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2746 change makes the evaluator safer at the cost of evaluation speed.
2747 It handles the case when the user has added a non-immediate
2748 improper end of the application form, e.g., `(+ 0 . x)'.
2749 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2750 minimize the extra cost as much as possible. The new code is
2751 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2752 problem with structs planted directly in the code (e.g. by a
2753 macro). This no longer causes segmentation fault. (Thanks to
2756 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2757 arg `proc' in order to be able to throw errors; New argument
2760 * Removed extra #include "debug.h"
2762 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2764 * scmsigs.c: Declare usleep as returning void on some systems.
2765 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2768 * coop.c (usleep): Return void on some systems.
2770 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2772 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2774 * coop.c: Changed return type of usleep to int.
2776 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2777 isn't found in the OS.
2779 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2780 isn't enabled. (Thought that I had made this change ages ago...)
2782 * iselect.c: Declare bzero if not defined by OS.
2784 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2786 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2787 condition. (Thanks to John Tobey.)
2789 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2790 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2793 * __scm.h: Start the long-term project of moving to POSIX threads.
2794 Phase 1: Classification of all critical sections.
2795 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2796 for A sections. (See comments in __scm.h for details.)
2798 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2799 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2801 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2803 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2804 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2805 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2806 dependencies on $(srcdir)/Makefile.in
2807 $(top_builddir)/config.status in order to avoid circularity.
2809 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2810 from argc if argc was 0 initially.
2812 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2813 in generation of libpath.h.
2815 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2817 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2818 libguile from 2 to 3.
2820 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2822 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2824 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2826 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2827 scm_set_port_column_x, scm_port_filename,
2828 scm_set_port_filename_x): Removed optional arguments. Added
2829 proper argument checking.
2831 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2832 stack size in machine words.
2834 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2835 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2836 to Ole Myren Röhne.)
2838 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2840 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2841 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2843 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2846 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2847 procedure apply: Copy argument lists before pushing them unto the
2848 environment so that the environment won't get mutated due to
2849 manipulation of procedure arguments. This should perhaps be
2850 regarded as a temporary solution until someone finds a more
2851 efficient one. (Thanks to Maciej Stachowiak.)
2853 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2855 * script.c (scm_compile_shell_switches): Use "guile" as default
2856 zero arg if argc is NULL.
2858 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2860 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2861 is zero. (Thanks to Dirk Herrmann.)
2863 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2865 * ports.c (scm_add_to_port_table): First line is now line 0
2866 (was 1). (Interface changed according to suggestion by Per
2869 * backtrace.c (display_header): Add 1 to line and column numbers
2870 when presenting them to the user.
2872 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
2873 from debug.c --> eval.c
2875 * eval.h, eval.c (scm_eval_options_interface): New options
2877 (SCM_EVAL_STACK): New option: Size of newly created stacks,
2878 i.e. stacks for new threads.
2880 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
2882 * eval.c (unsafe_setjmp): Removed with #if 0.
2884 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
2887 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
2888 to avoid compiler warnings.
2890 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
2892 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
2894 * throw.c (handler_message): Print message on current error port
2895 instead of default error port. (Thanks to Maciej Stachowiak.)
2897 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
2899 * ports.c (scm_add_to_port_table): allocate in units of
2900 struct scm_port_table *, not struct scm_port_table.
2901 * posix.c (scm_close_pipe): remove the port from the port table
2903 Thanks to Rob Engle for both fixes.
2905 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2907 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
2908 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
2910 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2912 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
2914 * backtrace.c (display_error_body, display_backtrace_body),
2915 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
2916 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
2917 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
2918 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
2921 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
2922 don't receive the jmpbuf arg anylonger.
2923 (scm_catch): Don't accept a #f tag.
2924 (scm_throw): Check that key is a symbol.
2925 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
2927 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
2929 * async.c (async_pending): Removed declaration.
2931 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2933 * dynwind.c (scm_wind_chain): New debug function.
2935 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
2936 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
2937 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
2938 extra layer of functions around the body and handler of a thread.
2939 This extra layer makes sure that the handler is called in the
2940 dynamic context of the surround (= empty dynwind list), but under
2941 the *dynamic root* of the body. We can not use the dynamic root
2942 of the surround since that root belongs to another thread => stack
2943 is not handled correctly. It may seem ugly to use this extra
2944 layer, but the extra cost in terms of execution time is really
2945 negligible compared to the total amount of time required to create
2946 a thread, and it would reduce maintainability to duplicate the
2947 crucial and complicated steps performed by cwdr.
2949 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
2950 (SCM_ALLOW_INTS): Added thread switching code before interrupts
2951 get re-enabled. The important effect of this is that interrupts
2952 are blocked during thread switching so that thread data structures
2953 don't risk getting messed up by an unfortunate signal.
2954 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
2955 seems to do more aggressive optimization which actually move
2956 instructions around in these macros in a fatal way. Therefore:
2957 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
2958 just superstitious...)
2959 (SCM_TICK): Maybe do a context switch and take care of asyncs.
2960 This macro should be used instead of SCM_ASYNC_TICK since the
2961 latter doesn't do context switches any more.
2963 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
2964 instead of SCM_ASYNC_TICK.
2966 * coop.c, iselect.c: Since thread switches are now performed with
2967 interrupts masked, we can't use the old mechanism of delivering
2968 signals immediately when they arrive. Signals must instead be
2969 delivered when the asyncs run *after* the end of the critical
2970 section in scm_internal_select. But this also means after context
2971 switch so that the signal will be delivered to a different thread.
2972 To avoid this, I have changed the protocol of
2973 coop_wait_for_runnable_thread and friends so that they are allowed
2974 to return the original thread. So, if a signal arrives during
2975 scm_internal_select, we won't any longer be forced do a context
2976 switch, but can remain in the same thread and deliver the signal
2979 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
2980 scm_asyncs_pending and made it global.
2982 * iselect.c: Small fixes.
2984 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
2985 coop_condition_variable_init, coop_condition_variable_wait,
2986 coop_condition_variable_signal): Changed return type from `void'
2987 to `int'. This is to adhere closer to the pthreads interface.
2988 This, in turn, is part of an attempt to provide C versions of the
2989 mutex and condition variable primitives which can be part of a
2990 frontend to COOP or pthreads.
2992 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
2993 coop_condition_variable_destroy): New functions.
2995 * coop-threads.c (scm_wait_condition_variable): Use
2996 coop_condition_variable_wait_mutex.
2998 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
2999 Definitions moved to coop-defs.h.
3001 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3002 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3003 scm_cond_destroy): New C interface to mutecis and cond vars.
3005 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3007 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3009 * iselect.c: Now several threads can wait on the same file
3010 descriptor. The behaviour is compatible with OS select: All
3011 threads waiting for the fd return with the same status.
3013 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3015 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3016 Can spawn a thread from application C code.
3018 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3020 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3021 gh_doubles2scm): New functions.
3023 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3025 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3026 commented-out version of gh_eval_str()
3028 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3030 * socket.c (scm_bind): free soka after use.
3032 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3034 * stime.c (tzvar): new variable.
3035 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3036 avoid memory leaks when allocating.
3038 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3040 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3043 * gc.c, tags.h: Doc fixes.
3045 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3047 * eval.c (macro-eval!): Removed. This function was a design bug.
3048 It allowed memoized code to leak out to the scheme level. Most
3049 things that you could do with `macro-eval!' can be done with
3052 1997-12-20 Tim Pierce <twp@skepsis.com>
3054 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3055 scm_fgets now depends on ftell(3) to know how many bytes were
3058 1997-12-15 Tim Pierce <twp@skepsis.com>
3060 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3061 dealing with strings.
3063 1997-12-13 Tim Pierce <twp@skepsis.com>
3065 Make %read-line more suitable for implementing read-line efficiently.
3066 * ioext.c (scm_read_line): Strip the terminating newline from a
3067 string, and return a cons of the string and its terminator.
3069 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3070 of the string that is read is stored in this memory location.
3071 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3072 * genio.c, genio.h (scm_do_read_line): Update caller.
3073 * ports.h (scm_ptobfuns): Update typedef.
3074 * fports.c (scm_fptob, scm_pipob): Update struct.
3076 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3078 * filesys.c (set_element): Return file descriptor.
3079 (fill_select_type): Return the highest file descriptor.
3080 (scm_select): Tell select about the highest file descriptor. On
3081 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3082 Therefore the extra overhead for calculating the maximum fd seems
3083 to be more than compensated. Is this correct? In any case,
3084 scm_internal_select will be much faster with this info.
3085 (scm_select, fill_select_type, set_element): Don't accept any kind
3086 of object in the file descriptor list or vector.
3088 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3090 * iselect.c (finalize_fd_sets): Bugfix.
3092 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3094 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3095 when using scm_internal_select (since we might switch to another
3098 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3100 * simpos.c (scm_system): always define: use sysmissing if not
3101 available. Check for HAVE_SYSTEM instead of _Windows (does
3102 Windows lack system or does it have an unusable one?).
3103 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3104 Let the argument be optional: if not supplied, call system(NULL).
3106 * ports.c (scm_close_port): relax the type check from OPPORTP to
3107 PORTP; closing a closed port is allowed.
3109 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3111 * fports.c (scm_fgets): Return if the last char in a chunk is
3112 newline. When fgets returns a string whose length is `size-1', it
3113 is ambiguous whether a whole line was retrieved, so we must check
3114 explicitly whether a line terminator is present.
3116 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3118 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3119 before taking the CDR. (Thanks to Harald Meland.)
3121 * filesys.c (scm_stat): Slightly optimized.
3123 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3125 * ports.c (scm_close_port): Make sure the port is open before
3128 * guile-snarf.in: Pass args through to gcc in a way that preserves
3129 whitespace boundaries. (Thanks to Greg Badros.)
3131 1997-12-02 Tim Pierce <twp@skepsis.com>
3133 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3134 statement. (Thanks to Doug Evans for pointing this out.)
3136 1997-12-01 Tim Pierce <twp@skepsis.com>
3138 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3140 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3142 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3143 errno macro expansion of this field name. (errno is a C
3144 preprocessor macro on some systems.)
3146 1997-11-29 Tim Pierce <twp@skepsis.com>
3148 * iselect.c: Doc fix.
3150 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3152 * init.c (scm_start_stack): Removed initialization of
3153 scm_the_last_stack_var.
3155 * backtrace.h: Declare scm_the_last_stack_var.
3157 * backtrace.c: Define scm_the_last_stack_var.
3159 * root.c (mark_root): Don't mark the_last_stack_var.
3161 * root.h (scm_root_state): Removed the_last_stack_var.
3163 * throw.c: Added #include "fluids.h"
3164 (ss_handler): `the-last-stack' is now a fluid.
3166 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3167 --> the_last_stack_fluid.
3169 * backtrace.c: Added #include "fluids.h"
3170 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3171 (scm_backtrace): `the-last-stack' is now a fluid.
3173 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3174 after scm_init_fluids.
3176 1997-11-28 Tim Pierce <twp@skepsis.com>
3178 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3180 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3181 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3183 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3185 * iselect.c (coop_next_runnable_thread,
3186 coop_wait_for_runnable_thread): Disable interrupts so that no
3187 async is executed before a potential error_revive.
3188 (scm_internal_select): Disable interrupts during the parts of the
3189 code which manipulate the sleep queue and the file descriptors.
3191 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3193 * Makefile.am: Added iselect.c and iselect.h.
3195 * coop.c (coop_qinit): Initialize fields used by
3196 scm_internal_select.
3197 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3198 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3199 replacement in iselect.c.
3200 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3201 coop_join): If GUILE_ISELECT enabled, use
3202 coop_wait_for_runnable_thread instead of
3203 coop_next_runnable_thread.
3204 (usleep, sleep): New replacements for system functions if
3205 GUILE_ISELECT is enabled.
3207 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3209 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3211 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3212 iselect.h. Implement Scheme level `select' using
3213 scm_internal_select. (See NEWS.)
3215 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3217 * init.c: Call scm_init_iselect.
3219 * iselect.h, iselect.c: New files. Implements
3220 scm_internal_select. (See NEWS.)
3222 1997-11-27 Tim Pierce <twp@skepsis.com>
3224 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3225 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3226 and scm_must_free, since ultimately the string returned will be copied
3227 by scm_makfrom0str anyway. Also, read any characters that may have
3228 been pushed onto the port with scm_ungetc.
3229 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3230 * ioext.c (scm_read_line): Free string after Guilifying it.
3231 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3233 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3235 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3237 * gh.h: Safely wrap prototypes for c++ usage.
3239 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3241 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3242 gh_repl (argc, argv).
3244 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3246 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3247 and to invoke scm_shell().
3248 (gh_launch_pad): took out the loading of boot-9.scm from here,
3249 since it is probably best to let the user control that. In fact,
3250 gh_repl() now invokes scm_shell() which does that.
3252 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3254 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3257 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3260 yesterday's underscore patch. (Thanks to Marius Vollmer for
3263 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3265 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3266 DLSYM_ADDS_USCORE is not defined.
3268 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3270 * gh_data.c (gh_uniform_vector_length):
3271 (gh_uniform_vector_ref): started implementing the uniform types in
3274 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3276 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3277 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3279 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3281 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3282 configure.in was changed).
3284 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3286 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3287 * Makefile.in: Regenerated.
3289 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3291 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3292 OPORT is an `open' port, not an output port.
3294 * filesys.c (scm_close, set_element, get_element, scm_chown,
3295 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3296 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3297 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3298 scm_close_port, scm_port_line, scm_set_port_line_x,
3299 scm_port_column, scm_set_port_column_x, scm_port_filename,
3300 scm_set_port_filename_x, scm_port_mode,
3301 scm_close_all_ports_except, scm_set_current_output_port,
3302 scm_set_current_error_port): Likewise
3303 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3304 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3306 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3307 * backtrace.c (display_backtrace_body): Likewise
3308 * fports (scm_setvbuf): Likewise
3309 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3310 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3311 scm_getpeername, scm_send, scm_sendto): Likewise
3312 * unif.c (scm_uniform_array_write): Likewise
3314 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3316 Minor problems with substring-related tag changes.
3317 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3318 exactly what we want to leave in to detect substrings.
3319 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3320 * tags.h: Fix diagrams and comments describing the S tag bit;
3321 remove vestigial remarks about the D tag bit.
3322 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3323 * strings.c: Formatting tweaks.
3325 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3326 variable first; then SCHEME_LOAD_PATH, with a warning message.
3327 (scm_parse_path): New function.
3328 * script.c: Doc fixes.
3330 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3332 Readline support, from Daniel Risacher.
3333 * readline.c, readline.h: New files.
3334 * init.c: #include "readline.h".
3335 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3336 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3337 * Makefile.in: Regenerated.
3338 * scmconfig.h.in: Regenerated, after change to ../configure.
3340 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3342 * gh.h: gh_vector_set -> gh_vector_set_x
3344 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3346 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3347 with the ! -> _x mapping when going from Scheme to C.
3349 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3351 * gh.h (gh_reverse):
3359 (gh_assoc): added these gh_ functions implemented as macros.

3362 (gh_string_equal_p): added these two missing predicates.
3364 * gh_list.c (gh_append):
3369 (gh_set_cdr_x): added these routines as I go through and try to
3370 complete the picture R4RS functions that should be mirrored in the
3373 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3375 * tags.h (scm_tc7_substring): Changed the comment and code to
3376 conform with the changes below. Folks! We have suddenly two new
3377 free tc7 codes!!! Jummy, jummy!
3379 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3381 * Makefile.in: Rebuilt.
3382 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3384 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.

3400 * tags.h (SCM_TYP7SD): Removed.
3401 (SCM_TYP7D): Removed.
3402 (scm_tc7_mb_string): Removed.
3403 (scm_tc7_mb_substring): Removed.

3406 Don't include "mbstrings.h".
3407 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3408 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3410 Don't include "mbstrings.h".
3411 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3412 (SCM_SYMBOL_SLOTS): Define as 4.
3413 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

3435 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3437 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3439 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3441 * gh_test_c.c (c_vector_test): some improvements on the vector
3444 * gh.h (gh_vector): this used to exist but do the wrong thing.
3445 Now it (almost) does the right thing, though it takes a list
3446 instead of the individual arguments. I need to see how it could
3448 (gh_list_to_vector): added this function as a macro. Corresponds
3449 to Scheme's (list->vector ...).
3450 (gh_vector_to_list): added this function as a macro. Corresponds
3451 to Scheme's (vector->list ...).
3453 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3454 gh_vector_ref, so that it resembles the Scheme routines more.
3455 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3456 resembles the Scheme routines more.
3457 (gh_make_vector): this used to be (stupidly) called gh_vector().
3458 This is the right name, since it does the same thing as the Scheme
3459 (make-vector ...) procedure.
3461 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3463 * ports.h: #include "libguile/print.h"
3465 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3466 Some indentation fixes.
3468 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3469 longer a user field; New field: class_flags.
3471 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3473 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3475 * gh_data.c (gh_bool2scm): new function which replaces
3476 gh_int2scmb(), which is now tagged as obsolete.
3478 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3480 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3481 macros should by convention not test for NIMPness.)
3482 (SCM_COERCE_OPORT): Adjust indentation.
3484 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3485 SCM_NIMP test before SCM_PRINT_STATE_P.

3491 scm_struct_i_printer --> scm_vtable_index_printer
3492 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3494 * struct.c (scm_print_struct): Use new printer slot; Default
3495 printing: Also output hex code of vtable so that type identity
3496 will be indicated as well.
3497 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3498 Removed struct_printer_var; Removed struct-vtable-offset;
3499 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3500 vtable-offset-user): New constants.
3502 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3503 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.

3505 the type represented by this vtable.
3507 * print.c (scm_iprin1): Don't print arguments of macro
3508 transformers. (They are always: exp env.); Bugfix: Unmemoize
3509 transformer source with correct environment.
3511 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3513 Streamlining of call-with-dynamic-root:

3516 there is now only one catch.
3517 (cwdr_outer_body): Removed.
3518 (cwdr_handler): New function.
3519 (scm_internal_cwdr): New function to perform the function of cwdr
3520 but take args that are more useful to C code. Also, the handler
3521 is now invoked *outside* of the new dynamic root, like the docs
3522 say. We no longer have to catch absolutely all errors, the caller
3523 is responsible for using a handler that does not throw, if he
3525 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3526 * root.h (scm_internal_cwdr): New prototype.
3528 Even more but risky streamlining:
3530 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3531 allocation of the jumpbuf of a root continuation. The changes
3532 below are controlled by it. They are now deactivated.
3533 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3534 the JMPBUF of the scm_rootcont to NULL before returning.
3536 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3537 when they are non-NULL.
3538 (scm_gc_mark): Likewise, mark only when non-NULL.
3540 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3541 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3543 * gc.c (scm_done_malloc): New function.
3544 gc.h (scm_done_malloc): New prototype.
3546 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3547 (struct scm_print_state) [revealed]: New field.
3548 (scm_print_state_vtable): Make visible to the outside world for
3549 type checking purposes.
3550 (scm_valid_oport_value_p): New prototype.
3552 * print.c (scm_valid_oport_value_p): New function to check whether
3553 a certain value is acceptable as a port argument.
3554 (scm_print_state_vtable): New variable.
3555 (scm_free_print_state): Set `revealed' field to false.
3556 (scm_iprin1): Call user supplied closure printer with
3557 scm_printer_apply. Print in the traditional way when there isn't
3558 one or when it returns #f.
3559 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3560 Accept a port/print-state pair in addition to just a port.
3561 (scm_prin1): Don't return the print_state to the pool when it has
3563 (scm_printer_apply): Set `revealed' field of print_state to true.
3564 (scm_init_print): Set scm_print_state_vtable.
3565 (print_state_fluid, print_state_fluid_num): Removed.
3567 * throw.h (scm_handle_by_proc_catching_all): New prototype
3568 throw.c (scm_handle_by_proc_catching_all): New function
3570 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3572 * Makefile.in: Regenerated with automake 1.2c.
3574 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3576 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3577 was looping endlessly.
3579 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3581 * strports.c (scm_eval_string): Don't close the port.
3583 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3584 former returns a nice normal integer. (Thanks to Daniel
3587 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3589 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3590 makefile variable as a build parameter called LIBS. The
3591 build-guile program will use this, for the time being.
3592 * Makefile.in: Regenerated.
3594 Thanks to Shiro Kawai:
3595 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3596 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3599 * Makefile.in: Regenerated with automake 1.2a.
3601 * script.c (scm_compile_shell_switches): If we hit the -c or --
3602 arguments, don't set the car of (command-line) to scm_usage_name,
3603 the prettified name of the guile executable; give it the full
3604 path, the way shells usually handle $0.
3606 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3608 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3609 Scheme-level name `array-map' and renamed `serial-array-map' to
3610 `serial-array-map!'.
3612 * backtrace.c: Introduced exception handlers which now enclose
3613 `display-error' and `display-backtrace' so that error reporting
3614 won't get into infinite loops if an error occurs during displaying
3615 of the error. This can very easily happen with user supplied
3616 print call-back routines.
3618 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3620 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3621 the names `serial-array-map' and `array-map' should be removed.)
3623 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3625 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3626 Added #include "objects.h"
3628 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3629 Add #include "feature.h".
3631 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3632 (modinclude_HEADERS): Added objects.h.
3634 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3635 This test is needed at many places in the code and should be
3636 abstracted. (Motivated by the need of this test in libguiletk.)
3638 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3639 (scm_eval_string), load.c (scm_primitive_load,
3640 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3641 Use SCM_EOF_OBJECT_P.
3643 * eval.c (scm_init_eval): Add feature `delay'.
3645 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * scmhob.h: Removed.
3649 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3651 * list.h (SCM_LISTn): New macros. Make list creation in C code
3652 prettier. The idea comes from STk.
3654 * sequences.h, sequences.c, append.h, append.c: Removed. These
3655 files implemented non-R4RS operations which would encourage
3656 non-portable programming style and less easy-to-read code.
3658 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3661 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3662 sequences.h, #include append.h.
3664 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3667 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3669 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3671 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3673 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3675 * eval.c: Added #include "objects.h"
3677 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3680 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3681 adjacent smob numbers.
3683 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3685 * procprop.h: Added declaration of scm_i_inner_name.
3687 * gsubr.c: New global symbol scm_i_inner_name.
3689 * debug.c (scm_procedure_name): Try procedure property
3690 `inner-name' if `name' fails.
3692 * print.c (scm_iprin1): Use scm_macro_name.
3694 * eval.c (scm_m_define): Give names to macros as well; Only the
3695 first top-level definition gives a procedure/macro a name.
3696 Otherwise confusing names can turn up in backtraces.
3697 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3698 `name'; Give names to macros as well.
3700 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3701 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3704 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3706 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3708 (prinmacro): Removed. The code has been moved/merged into print.c
3709 in order to decrease code redundancy. We want macros to print in
3710 a way equivalent to procedures, and it would be silly to duplicate
3711 the required code. (We don't want to maintain two places.)
3712 (macrosmob): Print field is now a NULL pointer.
3714 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3715 scm_macro_transformer): New prototypes.
3716 (scm_tc16_macro): Declared.
3718 * print.c (scm_iprin1): Added code for printing of macros. Macros
3719 are now printed in a way equivalent to procedures.
3721 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3723 * procs.h (scm_closure_p): Added declaration.
3725 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3727 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3728 Shouldn't pass "heap" as the subr name.
3730 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3732 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3733 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3734 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3735 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3736 SCM_BOOL_T. Any non-false value is true.
3738 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3740 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3741 scm_gensym): Added prototypes.
3743 * symbols.c (scm_gensym): New function. This will speed up
3744 certain types of applications (such as macro systems) which
3745 generate lots of symbols.
3747 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3749 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
3751 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
3753 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3754 specifier, since (2) or (2 . 3) would cause SEGV.
3755 (scm_transpose_array): more argument checking fixes.
3757 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
3759 * Makefile.in: Regenerated.
3761 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3763 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3765 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3767 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3769 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3771 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3772 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3775 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3776 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
3777 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
3778 scm_array_p, scm_array_rank, scm_array_dimensions,
3779 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
3780 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
3781 scm_array_prototype): Added case scm_tc7_wvect.
3783 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3785 * errno.h: prototype for scm_strerror.
3786 * error.c (scm_strerror): new procedure.
3788 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3790 * list.c (scm_list_append_x): Allow non-pair as last argument.
3791 This is consistent with the R4RS append and is probably the
3792 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3794 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3796 * stime.h: prototype for scm_times.
3797 * stime.c (scm_times): new procedure.
3798 * ioext.c (scm_fseek): if the first argument is a file descriptor
3800 (scm_ftell): if the first argument is a file descriptor call lseek
3802 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
3803 * filesys.c (scm_chmod): if the first argument is a file descriptor,
3805 (scm_chown): if the first argument is a port or file descriptor,
3807 (scm_truncate_file): new procedure.
3808 Add DEFER/ALLOW INTS to a few other procedures.
3809 (scm_fsync): new procedure.
3810 (scm_open_fdes): new procedure.
3811 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3813 (scm_fcntl): the first argument can now be a file descriptor. The
3814 third argument is now optional.
3816 * posix.c (scm_execl, scm_execlp): make the filename argument
3817 compulsory, since omitting it causes SEGV.
3818 (scm_sync): return unspecified instead of #f.
3819 (scm_execle): new procedure.
3820 (environ_list_to_c): new procedure.
3821 (scm_environ): use environ_list_to_c. disable interrupts.
3822 (scm_convert_exec_args): take pos and subr arguments and
3823 improve error checking.
3825 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3827 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3828 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3829 argument to SCM_ASSERT. Furthermore, the name of the function
3830 should be passed as first argument when signalling
3831 SCM_WNA. (Thanks to Thomas Morgan)
3833 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3834 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3835 dispatches on the number of actual args has a default case
3836 reporting an internal error. This is a vestige from a version
3837 that mallocated a SCM vector to hold the arguments. In the
3838 current version this check is too late: if it ever happens we will
3839 have already overstepped the bounds of the array.
3841 Also, the patch [...] adds a check for too many actual arguments."
3843 mdj: Removed check for "internal programming error".
3845 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3847 * gh_io.c (gh_write): New function.
3849 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3850 throw.c (scm_internal_stack_catch): New sibling to the other catch
3851 functions. Code moved from gh_eval.c.
3852 throw.h: Added header.
3853 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
3854 scm_internal_stack_catch.
3856 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3858 * ioext.h: fix up prototypes.
3859 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3860 Scheme name is now dup->fdes.
3861 (scm_dup_to_fdes): make the second argument optional and
3862 fold in the functionality of scm_primitive_dup.
3863 (scm_primitive_dup): deleted.
3865 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3867 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
3868 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
3869 ultrix are defined. Use setvbuf instead of setbuf.
3870 (scm_setvbuf): new procedure.
3871 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
3872 (scm_setfileno): moved from ioext.c.
3873 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
3874 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

3884 state as nested data while they are printed.
3885 (print_state_fluid, print_state_fluid_num): New variables.
3886 (scm_init_print): Initialize them.
3887 (scm_iprin): If print_state_fluid carries a print_state, use that
3888 instead of creating a new one.
3889 (scm_printer_apply, apply_stub, struct apply_data): New
3890 definitions to help with calling printer functions written in
3892 * print.h (scm_printer_apply): New prototype.

3905 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
3906 SCM_ASSERT: arg comes before pos.
3908 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3910 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
3911 to a list of length zero correctly.
3913 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

3929 * ioext.h: removed scm_duplicate_port prototype.
3931 * ioext.c (scm_primitive_dup2): return the new file descriptor
3932 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
3934 (scm_fdopen): bug fix: don't try to make port unbuffered until its
3935 stream has been set.
3936 (scm_duplicate_port): deleted, there's now an implementation in
3938 (scm_primitive_dup2): do nothing if newfd == oldfd.
3940 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
3942 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
3945 * ioext.h: new prototypes.
3946 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
3948 * fluids.c (next_fluid_num): don't do
3949 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
3951 * ports.h: prototypes too.
3952 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
3954 * fports.h: prototype too.
3955 * fports.c (scm_evict_ports): moved from ioext.c.

3982 (scm_make_root): Call scm_copy_fluids to make fluid bindings
3983 unique for the new root when it has a parent.
3985 * smob.h: Include "libguile/print.h" to make scm_print_state

3989 data. (dynl_smob): Use it.
3990 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
3991 the dynamic object data below the linking of the object to avoid
3992 memory leak when the linking code throws an error. Now the code
3993 leaks a whole dynamically linked library when must_malloc throws,
3994 but that should be much less likely.
3996 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
3998 Changes to compile under gnu-win32, from Marcus Daniels:
3999 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4000 (scm_localtime): Change SCM_EOF to SCM_EOL.
4001 (scm_mktime): Likewise.
4002 * socket.c: Don't include sys/un.h unless autoconf tells
4003 us Unix domain sockets are available.
4004 (scm_fill_sockaddr): Ignore Unix domain code.
4005 (scm_addr_vector): Likewise.
4006 (scm_init_addr_buffer): Likewise.
4007 (scm_socketpair): Don't include unless socketpair was
4008 found during autoconf.
4009 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4010 * scmsigs.c (scm_pause): Don't include unless pause was found
4012 * posix.c (scm_getgroups): Don't include unless support function
4013 was found during autoconf (in this case, getgroups).
4014 (scm_setpwent): For setpwent.
4015 (scm_setegid): For setegid.
4016 * net_db.c (scm_inet_netof): Don't include unless support
4017 function was found during autoconf (in this case, inet_netof).
4018 (scm_lnaof): For inet_lnaof.
4019 (scm_inet_makeaddr): For inet_makeaddr.
4020 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.
4021 (scm_getproto): For getprotoent.
4022 (scm_getserv): For getservent.
4023 (scm_sethost): For sethostent, endhostent.
4024 (scm_setnet): For setnetent, endnetent.
4025 (scm_setproto): For setprotoent, endprotoent.
4026 (scm_setserv): For setservent, endservent.
4027 * scmconfig.h.in: Regenerated.
4029 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
4031 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4032 scm_misc_error, not SCM_EOF.
4034 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4035 arguments for formatting the error message, not SCM_BOOL_F. I
4036 think this is left over from the (eq? '() #f) days.
4038 * read.c (recsexpr): Give this a dummy definition if
4039 DEBUG_EXTENSIONS isn't #defined.
4041 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4043 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
4046 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
4048 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
4051 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
4053 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4054 alloca.lo will be included in @LIBLOBJS@. Something better than
4055 this should be possible.
4056 * Makefile.in: Regenerated.
4058 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4060 * simpos.h: prototype for scm_primitive_exit.
4061 * simpos.c (scm_primitive_exit): new procedure, terminates the
4062 process without unwinding the stack.
4064 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4066 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4067 argument and logior its components together, so the user doesn't
4068 have to do this explicitly. Also, if regexp/basic is supplied, then
4069 turn off REG_EXTENDED.
4070 (scm_init_regex_posix): New regexp/basic symbol.
4071 (REG_BASIC): #define this if it is not already present.
4073 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4075 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
4076 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
4077 (CLEANFILES): New target, clean versiondat.h, libpath.h.
4078 (DISTCLEANFILES): New target, clean *.x.
4079 * Makefile.in: Regenerated.
4081 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
4083 * script.c (scm_compile_shell_switches): Add 1997 to copyright
4084 years in usage message.
4086 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
4087 * Makefile.in: Regenerated.
4089 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4090 flag; I don't think we support it.
4091 (scm_make_regexp): Make sure the user doesn't pass the
4094 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4096 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4097 name them according to the SCSH convention: regexp/mumble.
4099 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4101 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
4103 * Makefile.am (libpath.h): Include the values of all the standard
4104 Makefile directory variables. Print a message, but don't print
4106 (versiondat.h): Print a message, but don't print all the commands.
4107 * load.c: #include "alist.h".
4108 (init_build_info): New function.
4109 (scm_init_load): Call it.
4110 * Makefile.in: Regenerated.
4112 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4114 * root.c: Establish a reliable catch-all handler for the new root.
4115 After all the Scheme handler function might signal an error too,
4116 and we don't want to lose that.
4117 (cwdr_inner_body): Renamed from cwdr_body.
4118 (cwdr_outer_body): New function, to establish the user's handler,
4119 and pass control to cwdr_inner_body.
4120 (cwdr): Establish the reliable catch-all handler here, and pass
4121 control to cwdr_outer_body.
4122 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4123 the user's handler through to cwdr_outer_body.
4124 * throw.c (scm_handle_by_message): Move guts into....
4125 (handler_message): New static function.
4126 (scm_handle_by_message_noexit): New function.
4127 * throw.h (scm_handle_by_message_noexit): New prototype.
4129 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4130 across this. Only works on GCC. Otherwise, we hope for the best.
4131 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4132 the feeling that real thread systems will not need this...
4134 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4136 Try to detect when people are using one version of libguile and a
4137 different version of ice-9. People have been skewing things and
4138 sending in bug reports.
4139 * Makefile.am (versiondat.h): New file to generate.
4140 * version.c: #include "versiondat.h", to get version info.
4141 (scm_libguile_config_stamp): New function.
4142 * script.c: #include "version.h".
4143 (scm_compile_switches): Call scm_version to get version number.
4144 * scmconfig.h.in, Makefile.in: Regenerated.
4145 * Makefile.in: Regenerated.
4147 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4148 primitive definitions under their Scheme names.
4150 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4151 1:2. Helps avoid confusion between installed and uninstalled libs.
4153 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4156 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4157 backslash from definition; this should be used like: GDB_INTERFACE;
4159 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4161 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4162 new port unbuffered until its stream has been set.
4164 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4166 * ports.h: new prototype.
4167 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4169 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4171 Make things compile neatly under Sun's C compiler.
4172 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4173 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4174 unsigned, because that's what the ANSI function takes.
4175 * extchrs.h (xmbtowc): Corresponding change to prototype.
4176 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4178 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4179 argument plain char *.
4180 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4182 * tag.c (scm_tag): Remove unreachable statement.
4183 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4184 top of the word, it should be unsigned.
4186 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4187 is defined, to avoid warnings; it's only used in the
4188 conflict-checking code. Which might go away anyway.
4189 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4190 conditionals; put the label definition in an #if too, to stifle
4193 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4194 ChangeLog-threads in the distribution.
4195 * Makefile.in: Regenerated.
4197 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4199 * guile-snarf.in: Changed regexp to support CPPs that insert
4200 whitespace between lexical tokens (which munges the `%%%' snarf
4203 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4205 * load.c (scm_init_load_path): Append $(datadir)/guile to
4206 %load-path, so modules do not have to be installed in Guile's
4207 current version directory.
4209 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4211 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4212 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4213 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4214 call the sysdep functions with deferred ints.
4215 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4216 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4217 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4220 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4223 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4225 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4227 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4229 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4232 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4234 * eval.c (scm_lookupcar1): New procedure to cope with a race
4235 condition during lookup (when using threads).
4236 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4237 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4240 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4242 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4243 supplied. (Change from Tim Pierce.)
4245 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4247 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4248 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4249 default and not `()'. `#f' is the canonical non-value in Scheme,
4252 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4254 * struct.c (struct_printer): New variable that holds a handle on
4255 the Scheme variable *struct-printer*. This variable can be set by
4256 Scheme code to override the printing of structures.
4257 (scm_print_struct): If struct_printer is set, call it. If it is
4258 not set, or returns #f, print the structure in the old fashion.
4259 Include "eval.h" for scm_apply.
4261 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4263 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4264 scm_struct_i_n_words to get the number of fields, not
4265 -scm_struct_n_extra_words.
4267 On the route to fancier struct printing:
4268 * struct.c (scm_print_struct): New function to print a structure.
4269 Include "genio.h" to support it. This function doesn't do
4270 anything interesting right now, but I think it should be here
4272 * struct.h: Include "print.h" and add prototype for
4274 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4275 print structures ourself.
4277 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4279 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4280 before applying the handler in case it doesn't return.
4282 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4284 * scmsigs.h, async.h: updated.
4286 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4289 * posix.c (scm_uname): interpret only negative values as an error.
4290 Solaris normally returns a positive value.
4292 * script.c (scm_compile_shell_switches): if we are not going into
4293 an interactive repl, set scm_mask_ints to zero so that asyncs can
4296 * simpos.c (scm_system): don't ignore/unignore signals around
4299 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4302 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4303 done in boot-9.scm instead.
4305 * scmsigs.c, async.c: Major rewriting of signal handling code.
4306 (scm_sigaction): new procedure.
4307 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4309 (scm_raise): return unspecified, throw error on failure.
4311 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4313 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4314 feature, to help boot-9.scm decide whether to import the regex
4317 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4319 * eval.c: Include scmconfig.h at the beginning of the file so that
4320 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4323 * regex-posix.c: #include "_scm.h" before conditionally #including
4324 <regex.h>; the former defines HAVE_REGCOMP.
4326 * regex-posix.c: #include <regex.h> conditionally, so the file is
4327 CPP'able (for dependency scanning) even on systems that don't have
4330 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4332 Add new R4RS-compliant syntax for keywords.
4333 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4334 regardless of the setting of the `keywords' read option.
4335 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4336 can be re-read no matter what the setting of the `keywords' read
4339 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4341 Add support for POSIX regular expressions.
4343 * regex-posix.c, regex-posix.h: New files. (Some code
4344 is taken liberally from rx/rgx.c in the old Guile dist.)
4346 * init.c: Include regex-posix.h.
4347 (scm_boot_guile_1): Call scm_init_regex_posix.
4349 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4350 Add regex-posix.[ch] sources.
4351 * Makefile.in: Regenerated.
4353 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4354 to do this automatically? It didn't for me, bleh.)
4356 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4358 * fports.c (print_pipe_port): New function.
4359 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4360 latter doesn't even take the right arguments.
4362 * Makefile.am: Increment shared lib revision number. I think
4363 sometimes the uninstalled Guile finds the installed shared lib;
4364 Gord says doing this might help. As things turned out, I can't
4365 say whether it does.
4366 * Makefile.in: Regenerated.
4368 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4369 passing it as the closure argument to scm_boot_guile. (Bill
4372 * ports.c (print_void_port, putc_void_port, puts_void_port,
4373 write_void_port, flush_void_port, getc_void_port, close_void_port,
4374 noop0): Use ANSI prototypes instead of K&R declarations, so the
4375 initialization of void_port_ptob gets aggressively type-checked.
4376 Fix arguments of print_void_port and write_void_port. (Bill

4410 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4412 * script.c (scm_find_executable): Use prototype-style definition
4413 here; apparently it's not quite right to have const in a prototype
4414 and then use a K&R declaration. I wonder if stuff like this will
4415 go away if we compile with -Wrequire-prototypes, or whatever that
4416 is... (Bernard URBAN)
4418 * scmhob.h: New text from Bernard URBAN.
4420 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4422 * script.c: Don't #define const on hpux. Configure takes care of
4423 this. (Thanks to Larry Schwimmer.)
4425 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4426 decide whether to #include <unistd.h>, instead of listing a bunch
4427 of systems. Don't #include stdio twice. Removed dyked-out
4428 definition of scm_find_impl_file.
4430 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4432 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared

4442 significantly in 1997, but only had copyright years for 1996.
4443 Also, change name of copyright holder on some from Mikael
4444 Djurfeldt to Free Software Foundation; he has signed papers
4445 assigning the changes to the FSF.
4447 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4448 reason not to give the user the option.
4450 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4451 Return #f on end-of-file when scanning table (i.e. when called
4452 with no arguments). Try to catch errors, when we can.
4453 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4455 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4456 external declarations. These are useful.
4458 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4460 * posix.c: don't include <sys/select.h> or define macros for
4461 select, since they were not used in this file.
4463 * filesys.c (scm_select): make the fifth parameter microseconds,
4464 not milliseconds. let the fourth parameter be either a real value
4465 or an integer or #f. The first, second and third arguments can
4466 now be vectors: the type of the corresponding return set will be
4468 (set_element, get_element): new static procedures.
4470 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4472 * strports.c (scm_eval_string): New function.

4479 * fports.c (local_pclose): New function.
4480 (scm_pipob): Use it in the initializer here.
4483 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4484 Use a meaningful error message when signalling an error. For
4485 this, scm_gethost must check h_errno rather than errno.
4487 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4489 * Makefile.in: Regenerated, using automake-1.1p.
4491 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4493 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4494 not SCM_UNSPECIFIED.
4496 * script.c (scm_compile_shell_switches): don't append (quit) if
4498 (scm_shell): call scm_exit_status and exit on the result of the
4501 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4503 Ensure that shared substrings are handled properly when passed to
4504 a system call or other foreign function. Many thanks to Tim
4506 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4507 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4508 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4509 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4510 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4511 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4512 (scm_display_error_message): use RO macros when strings may be RO.
4513 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4514 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4515 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
4516 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
4517 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
4518 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
4519 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4520 scm_strftime), vports.c (scm_make_soft_port): use
4521 SCM_COERCE_SUBSTR to make sure shared substrings are

4526 * error.c (scm_error): Add newline to error message.
4528 * init.c (scm_init_standard_ports): Doc fix.
4530 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4532 * dynl-shl.c: Completely replaced with new code from Bernard
4535 * script.c (scm_ice_9_already_loaded): New variable.
4536 (scm_compile_shell_switches): Use it.
4538 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4540 * filesys.c (scm_input_waiting_p): add missing third argument to
4543 * stime.c (scm_localtime): copy the result of localtime before
4544 calling gmtime in case they share a buffer.
4545 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4548 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4550 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4552 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4554 * Makefile.am (check-local): New target, which causes 'make check'
4555 to run gh_test_c and gh_test_repl, with some trivial input.
4556 * Makefile.in: Rgnrtd.
4558 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4560 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4563 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4565 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4566 sure how this was supposed to work.
4567 (scm_async_click): don't send SCM_TICK_SIGNAL.
4568 (scm_init_async): don't initialize %tick-thunk.
4570 * the following change doesn't affect the Scheme interface:
4571 gc-thunk is called at the end of garbage collection. however it's
4572 no longer implemented by pretending it's a signal.
4574 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4575 system async corresponding to scm_gc_thunk.
4576 * async.h: declare scm_gc_async.
4577 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4578 gc-thunk directly, instead of going through a signal handler.
4579 (scm_gc_async): new variable, points to the GC system-async.
4580 (scm_init_async): save the GC async as scm_gc_async instead
4581 of using system_signal_asyncs.
4582 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4584 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4586 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4587 Don't screw up if we're interrupted.
4588 * Makefile.in: Regeneradet.
4590 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4592 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4594 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4595 we're not using AM_INIT_GUILE_MODULE any more.
4596 * Makefile.in: Reneregated.
4598 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4600 Functions for finding variable bindings, grace à Tim Pierce.
4601 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4602 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4604 Get 'make dist' to work again.
4605 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4606 * Makefile.in: Regenerated, like a surry without a fringe on top.
4608 Changes for reduced Guile distribution: one configure script,
4610 * configure.in, configure: Removed.
4611 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4612 real configure script lives.
4613 * Makefile.in, scmconfig.h.in: Regenerated.
4615 * init.c: #include "script.h", to get prototype for script.c's
4618 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4620 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4621 scm_must_malloc, not raw malloc.
4623 * script.c (scm_compile_shell_switches): Dyke out debugging output
4626 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4628 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4630 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4631 system has them. Hope this is safe. Previously
4632 sys/timeb.h was included if HAVE_FTIME was defined or if
4633 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4634 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4636 * ioext.c (scm_setfileno): add missing third argument to
4637 scm_misc_error call.
4639 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4641 * eq.c (scm_equal_p): Correctly compare strings of different
4642 varieties. (Thanks to Tim Pierce.)
4644 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4646 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4647 #! block comment must occur on a line all by itself.
4649 Move most of the guts of shell command processing into libguile,
4650 so guile.c can be very small (and eventuallly auto-generated. (I
4651 mean, generated mechanically, not self-generated. Hmm.))
4652 * guile.c, script.c, script.h: New source files.
4653 * init.c (scm_boot_guile_1): Call scm_init_script.
4654 * libguile.h: #include "script.h".
4655 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4656 targets, for new executable.
4657 (libguile_la_SOURCES): Mention script.c.
4658 (modinclude_HEADERS): Add script.h.
4659 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4660 not dynamic linking is enabled. This is because we're generating
4661 executables now. Move CY_AC_WITH_THREADS call after those, so the
4662 values of cy_cv_threads_libs captures the libs chosen above.
4663 * Makefile.in, configure, aclocal.m4: Regenerated.
4665 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4666 We don't maintain this interface any more, and it just confuses
4669 * alloca.c: #include <scmconfig.h>, not <config.h>.
4670 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4671 it'll get included in disties.
4673 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4675 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4676 be distributed, because they confuse people.
4677 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4679 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4681 * configure.in: check for presence of gethostent (not present on
4682 OpenBSD by default).
4683 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4684 * configure, scmconfig.h.in: Regenerated.
4686 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4688 * backtrace.c (scm_backtrace): Split message string across
4689 newlines properly. GCC is more tolerant of this than other
4692 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4694 Merge threads directory into libguile.
4695 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4696 threads.h: New source files.
4697 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4698 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4700 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4701 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4702 coop-threads.c.cygnus, coop-threads.h.cygnus.
4703 * configure.in: If we're using threads, include threads.o in
4705 * _scm.h, libguile.h: threads.h lives in this directory now.
4706 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4707 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4708 currently used, but brought along for information's sake.
4709 * ChangeLog-threads: log from old 'threads' directory.
4710 * Makefile.in, configure: Rebuilt.
4712 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4714 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4717 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4719 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4721 Merge GH interface library into libguile.
4722 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4723 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4724 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4725 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4727 (EXTRA_libguile_la_SOURCES): ... here.
4728 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4729 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4730 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4731 New variables, describing how to build the gh test programs.
4732 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4733 build the test programs, and we probably should have been linking
4734 libguile.la against them all along, to support AIX shared libs.
4735 Add cflags for threads to CFLAGS; add libs for threads to new
4736 variable THREAD_LIBS, used in Makefile.am.
4737 * ChangeLog-gh: log from old `gh' subdirectory.
4738 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4740 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4742 * acconfig.h: Undo change of Apr 9; including the definition of
4743 PACKAGE in the guile headers conflicts with applications' own
4745 * scmconfig.h.in: Regenerated.
4747 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

4751 * filesys.h: Added prototype.
4753 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
4754 when PROC is receiving no arguments.
4756 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4758 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4759 have S_IFSOCK. This is the case under Ultrix.
4761 * posix.c (scm_status_exit_val, scm_status_exit_val,
4762 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4763 Ultrix versions of WIFSTOPPED, etc., which assume that their
4764 arguments are lvalues (hmm).
4766 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4768 * eval.c: Doc fixes.
4770 * throw.c: Doc fixes; rearranged.
4772 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
4774 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
4776 * acconfig.h: Added entry for PACKAGE.
4777 * scmconfig.h.in: Regenerated.
4779 Changes to work with automake-1.1n, which has better libtool support.
4780 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4781 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
4783 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
4785 * Makefile.in: Rebuild.
4787 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4789 * stime.c (scm_mktime): take an optional zone argument.
4790 (scm_localtime): check putenv return value.
4791 (scm_strftime, scm_strptime): moved from posix.c. move #include
4793 stime.h, posix.h: update prototypes.
4794 (bdtime2c, setzone, restorezone): new static procedures.
4795 (scm_mktime, scm_strftime): use them.
4796 (scm_strftime): don't call mktime before strftime. Use
4797 filltime for return value.
4798 (filltime): convert NULL zname to #f.
4799 (scm_strptime): return a count of characters consumed, not
4800 the remaining string.
4802 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4804 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
4805 (scm_mktime): likewise.
4807 Uncomment localtime and mktime.
4809 * configure.in: add AC_STRUCT_TIMEZONE.
4811 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4813 * stime.c (scm_init_stime): don't define ticks/sec.
4814 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4815 return value problem and is still portable.)
4817 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4819 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4820 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4821 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4822 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4823 cpp_err_symbols.c): Corresponding changes.
4824 * Makefile.in: Regenerated.
4826 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4828 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4829 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4830 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4831 * putenv.c: new file, from sh-utils 1.12.
4833 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4834 since allocation isn't for Scheme objects.
4835 (scm_putenv): copy strings before placing in the environment.
4837 * stime.c (scm_current_time): throw an error if time returns -1,
4838 instead of returning #f.
4839 (scm_get_internal_real_time, scm_get_internal_real_time): use
4840 scm_long2num for return value instead of SCM_MAKINUM.
4842 * stime.h: prototypes updated.
4844 * stime.c (scm_time_in_msec): apparently unused, deleted.
4846 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4848 * configure.in: check for gettimeofday.
4850 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4851 which may be more usefully portable than a gettimeofday interface.
4853 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4855 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
4857 * Makefile.in: Regenerated.
4859 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
4861 * stime.c (filltime): recovered static procedure.
4862 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4865 * posix.h: add prototype for scm_close_pipe, remove prototypes for
4866 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
4868 * posix.c (scm_mknod): split the mode argument into type and perms
4869 arguments, like the extra fields returned by stat.
4871 * fports.c (scm_pipob): set the close, free and print procedures.
4872 (scm_close_pipe): new procedure.
4874 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
4875 define them in boot-9.scm
4877 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4879 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4880 wan't defined. Don't include fd.h.
4882 * Previously fd.h was regenerated whenever configure was run,
4883 forcing a couple of files to be recompiled.
4885 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
4886 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
4887 Check for _fileno as well as _file.
4889 * ioext.c: don't fd.h.
4890 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
4893 * Change the stratigy for getting information about errno
4894 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
4895 generating lists of symbols during the build process, which will
4896 not always work, include comprehensive lists in the distribution.
4897 To help keep the lists up to date, the "check_signals" and
4898 "check_errnos" make targets can be used.
4900 * configure.in: don't check for a command to extract errno codes.
4901 * Makefile.am: update file lists, remove errnos.list and errnos.c
4902 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
4903 check_errnos targets.
4904 (CLEANFILES): remove errnos.c and errnos.list, add
4905 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
4906 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
4907 * errnos.default: deleted.
4908 * cpp_signal.c: new file.
4909 * cpp_errno.c: renamed from errnos_get.c.
4910 * cpp_err_symbols, cpp_sig_symbols: new files.
4911 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
4912 * error.c (scm_init_error): #include cpp_err_symbols instead of
4914 * posix.c (scm_init_posix): don't intern signal symbols. #include
4917 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
4919 * strop.c (scm_i_index): allow the lower bound to be equal to the
4920 length of the string, so a null string doesn't always give an error.
4922 * posix.h: new prototypes.
4923 * posix.c (scm_status_exit_val, scm_status_term_sig,
4924 scm_status_stop_sig): new functions, as in scsh. They break down
4925 process status values as returned by waitpid.
4927 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
4929 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
4930 configure doesn't know about it.
4932 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4934 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
4936 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
4937 which defines C variables with global linkage.
4939 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4941 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
4944 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
4946 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
4947 has time to check why this doesn't work well with continuations.
4949 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
4951 * Fix shell syntax error; some shells won't tolerate
4952 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
4954 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4956 * posix.c (scm_uname): throw an error if uname fails instead
4959 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
4961 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
4964 * async.c (scm_ints_disabled): definition moved from error.c.
4966 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4968 * acconfig.h: Removed PACKAGE.
4970 * scmconfig.h.in: Regenerated.
4972 * snarf.h: g++ says it's non-portable not to specify the first
4973 argument in a varargs declaration. I introduced the first
4974 argument by using preprocessor conditionals.
4976 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
4978 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
4979 (scm_freopen): use RO string macros for filename and modes.
4980 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
4982 * posix.c (scm_getgrgid): simplify conversion of name to C string.
4983 (scm_mknod): use RO string macros for path.
4985 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
4986 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
4988 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4989 use SCM_ROSTRINGP and SCM_ROCHARS.
4991 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4993 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
4996 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
4997 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
4998 support for byte vectors.
5000 * print.c (scm_iprin1): Limit number of vector elements printed
5001 according to pstate->length.
5003 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5005 * backtrace.c (scm_display_error_message): don't segv if message
5008 * error.h: prototype for scm_error_scm.
5010 * error.c (scm_error_scm): new procedure, reimplements scm-error
5011 in C and uses scm_error.
5013 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5015 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5016 pointer to the Scheme variable read-hash-procedures and intern it
5017 in scm_init_read. Modify scm_read_hash_extend and
5018 scm_get_hash_procedure to use the pointer.
5020 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5022 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5023 (SCM_KEYWORD_STYLE): defined.
5025 * read.c (scm_read_opts): add a keywords option. This isn't a
5026 boolean option, in case someone wants to add support for DSSSL
5028 Setup scm_keyword_prefix symbol.
5029 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5031 I've left keyword support disabled by default, since it doesn't
5032 seem to break the module system and it gives R4RS standard behaviour.
5033 It can be reactivated with (read-set! keywords 'prefix).
5035 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5037 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5038 before constructing arbiter.
5040 * eval.c (scm_m_define): Bugfix: Check that the object is a
5041 closure before setting the procedure property!
5043 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5045 * ports.c: Removed `ungetc-char-ready?'.
5047 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5049 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5050 (idea from Mikael: make it a pair so scm_permanent object only
5052 (scm_read_hash_extend): don't call scm_permanent_object.
5053 (ideas from Mikael): if chr is already in the list, replace its
5054 procedure instead of appending it again. If proc is #f, remove
5056 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5058 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5060 * gdbint.c (gdb_read): update scm_lreadr usage.
5062 * load.h: update prototypes.
5064 * load.c (scm_primitive_load, scm_read_and_eval_x,
5065 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5067 * read.h: add prototype for scm_read_hash_extend. Change args for
5070 * read.c (scm_read_hash_procedures): new variable.
5071 (scm_read_hash_extend): new procedure.
5072 (scm_get_hash_procedure): new procedure.
5073 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5074 for extended # processing.
5075 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5076 scm_read_token): remove case_i, sharp arguments. Change callers.
5078 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5080 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5081 (SCM_CASE_INSENSITIVE_P): define.
5083 * read.c: add case-insensitive option to scm_read_opts.
5084 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5085 to determine whether to convert symbol case.
5086 (default_case_i): definition removed.
5087 * read.c (scm_read_token): if case_i, downcase ic before doing
5090 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5092 * configure.in: Added configuration option `guile-debug'.
5093 Configure with --enable-guile-debug if you want a bunch of extra
5094 functions used for debugging when developing Guile.
5096 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5098 * procs.c (make-cclo): New undocumented debugging procedure: Make
5099 compiled closure with internal procedure PROC and length LENGTH.
5100 Only compiled if GUILE_DEBUG is defined.
5102 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5104 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5106 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5108 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5109 with 3 or more args internally to the evaluator.
5111 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5113 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5114 with 3 or more args internally to the evaluator. This is mainly
5115 because we don't want to pass entry and exit points of the
5116 debug support twice, but it also seems to increase the speed of
5117 the evaluator for such calls (e. g. (+ 1 2 3)).
5119 * backtrace.c (scm_display_application): New procedure:
5120 display-application; Set fancy printing parameters individually
5121 for different types of display (backtrace, error, application).
5122 (These should of course be customizable!)
5124 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5125 clear the CHECK-flags.
5127 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5129 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5131 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5133 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5134 from pairs with a GLOC in the car.
5136 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5137 otherwise `symbol-hash' will behave badly.
5138 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5139 we get segmentation fault!
5141 * symbols.c: Added #include "weaks.h". New functions:
5142 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5143 moved to an extraneous library when we split libguile.)
5145 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5147 * filesys.c (scm_stat): stat now takes fport arguments too as
5148 documented in the manual.
5150 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5152 * debug.c (scm_single_step): Bugfix: Call continuation with
5153 scm_call_continuation instead of throwing to it.
5155 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5157 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5158 argument wasn't declared to be optional.
5160 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5162 * stime.c (scm_init_stime): Add feature "current-time".
5164 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5166 * throw.h: prototype for scm_exit_status.
5167 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5168 args to derive an exit status. Allows (quit) to work from a
5170 (scm_exit_status): new function.
5173 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5175 * eval.c (scm_deval): Removed some old code.
5176 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5178 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5181 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5184 * procs.c: Introduce the existent C function scm_thunk_p at the
5185 Scheme level as well.
5187 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5189 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5190 used from C to easily lookup the value of a symbol in the current
5193 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5195 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5196 scm_init_unif in this file. This will also fix a previous problem
5199 * configure.in: Added AM_MAINTAINER_MODE
5201 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5203 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5206 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5208 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5209 source files that are not always included in libguile but should
5210 have their dependencies calculated by automake. This variable is
5211 recognized by automake, no further magic is needed.
5212 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5213 to deal exclusively with *.lo files, as it seems. The *.o files
5214 are built automatically when the corresponding *.lo file gets
5217 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5219 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5222 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5224 * unif.c (scm_array_set_x): minor change to argument error checking.
5226 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5228 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5229 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5230 They should only be included in the library at configure.in's
5232 (libguile_la_LDADD): Include the appropriate .lo files here.
5233 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5234 so we know when to build them (and their .lo bretheren).
5235 * configure.in (LIBLOBJS): New substituted variable. We let
5236 configure decide which .o files to include in LIBOBJS, and then
5237 put the corresponding list of .lo files in LIBLOBJS. The latter
5238 is what we pass to libtool.
5239 * Makefile.in, configure: regenerated.
5241 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5243 * symbols.c (scm_sysintern0): New function. Contains the core of
5244 old scm_sysintern but doesn't take a second value argument.
5245 (scm_sysintern): Now uses scm_sysintern0.
5246 (scm_sysintern_no_module_lookup): Renamed to
5247 scm_sysintern0_no_module_lookup and doesn't take a second value
5248 argument any longer.
5250 * symbols.h (scm_sysintern0: Added declaration.
5252 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5253 scm_sysintern when interning option keys. Otherwise we risk
5254 destroying the values of already interned variables.
5256 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5257 scheme-level boolean (use SCM_NFALSEP).
5259 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5261 (scm_backtrace): New function. (C version of old function from
5262 boot-9.scm) Motivation: Make it possible to display backtraces
5263 without depending on boot-9.scm. (I'm uncertain if this
5264 motivation is good enough...)
5266 * root.h (scm_root_state): Add member the_last_stack_var.
5267 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5269 * root.c (mark_root): Mark scm_the_last_stack_var.
5271 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5274 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5276 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5277 1. mark_lazy_catch didn't mark the smob.
5278 2. Both functions above have standard variants:
5279 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5280 free_lazy_catch --> scm_free0.
5282 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5284 * throw.c (scm_internal_lazy_catch): New function.
5285 (scm_lazy_catch): Rewritten to use it.
5286 (scm_ithrow): Handle the new lazy catch representation.
5287 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5288 that doesn't have a jmpbuf is a lazy catch clause.
5289 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5290 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5291 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5293 (scm_init_throw): Register the new lazy-catch smob type.
5294 * throw.h (scm_internal_lazy_catch): decl for new function.
5296 * throw.c (scm_internal_catch): Doc fixes.
5298 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5299 configure.in. Including this might cause problems if applications
5300 that link against libguile include their own copies of alloca, but
5301 if they're using autoconf, they should be adding libguile to LIBS
5302 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5303 the copy in libguile, and things will be okay. (I think.)
5305 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5307 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5309 strop.h: move prototypes too.
5311 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5313 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5316 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5317 etc. I deleted them from filesys.c long ago, but didn't
5318 notice they were here too (although ineffective since
5319 sys/stat.h wasn't included).
5321 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5323 * eval.c: Don't define alloca in GCC case. gcc will automatically
5324 use __builtin_alloca if appropriate.
5326 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5328 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5329 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5330 that values of automatic variables are preserved. See comments
5331 for safe_setjmp for details.
5333 Change from Thomas Morgan:
5334 * variable.c: Include eq.h.
5335 (var_equal): New function.
5336 (variable_smob): Use var_equal as the discriminator for variables.
5338 * throw.c (s_throw): Remove extraneous declaration.
5340 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5341 * eval.c: Add necessary CPP cruft to support that.
5342 * configure, Makefile.in, scmconfig.h.in: regenerated.
5344 Change from Thomas Morgan:
5345 * procprop.c (scm_procedure_properties): Convert the Scheme
5346 boolean returned by scm_procedure_p into a C boolean before using
5347 it as a condition for SCM_ASSERT.
5348 (scm_procedure_property): Likewise.
5350 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5351 indications of Unixness.
5354 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5356 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5358 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5360 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5361 "unknown # object" error messages.
5363 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5364 (scm_i_index) and declare it static. Add a 'direction' argument
5365 to indicate what way the search should go.
5366 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5368 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5369 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5371 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5373 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5375 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5376 to avoid clash with various scsh forks.
5378 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5380 The following two changes (ramap.c, throw.c) are motivated by the
5381 apparent unportability of forward declarations of static arrays of
5382 the form `static foo bar[];'.
5384 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5385 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5387 * throw.c (scm_throw): Moved above scm_ithrow.
5389 * options.h: Removed the extern declarations of scm_yes_sym and
5390 scm_no_sym since these are static.
5392 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5394 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5396 * Makefile.am: remove AWK=@AWK@.
5397 Add a rule for generating errnos.list.
5398 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5400 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5401 don't extract errnos, just set a variable (avoids the
5402 need to recompile error.c just because configure is run.)
5404 * unif.h: update prototypes.
5405 * unif.c (scm_uniform_array_read,write): change the offset and
5406 length arguments to start and end, for consistency.
5408 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5410 * ioext.h: update prototypes.
5411 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5412 scm_read_line_x, it's a more general procedure using an
5413 interface from scsh. read-line and read-line! are now defined
5415 Note that the new read-line trims the terminator
5416 by default, previously it was appended to the returned string. An
5417 optional argument specifies how to process the terminator (scsh
5418 compatible). For the old behaviour: (read-line port 'concat).
5419 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5420 returns a pair, but is converted to multiple values if the scsh
5423 socket.h: update prototypes.
5424 * socket.c (scm_recvfrom): for consistency with other procedures,
5425 take start and end as separate optional arguments.
5426 (scm_recv, scm_recvfrom): don't allow the second argument
5427 to be a size, only a buffer. Change the scheme names to
5428 recv! and recvfrom!. Don't return the buffer.
5430 * ioext.h, posix.h: move prototypes too.
5431 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5432 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5433 "read.h" and "unif.h".
5434 * ioext.c: include "chars.h"
5436 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5438 * dynl.c: The dynamic linking and module registration functions
5439 are now defined even when dynamic linking is not available for the
5440 host system. Some of their functionality can be done without
5441 dynamic linking; when it's really needed, they throw errors.
5443 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5445 * configure.in: Only define DYNAMIC_LINKING when one of the system
5446 dependent functions is detected.
5447 * dynl.c (scm_dynamic_func): New function to get the address of a
5448 function in a dynamic object.
5449 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5450 produced by scm_dynamic_func as the thing to call.
5452 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5454 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5455 (scm_register_module_xxx, scm_registered_modules,
5456 scm_clear_registered_modules): New functions.
5458 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5460 * symbols.c (scm_sysintern): Renamed to
5461 scm_sysintern_no_module_lookup.
5462 (scm_sysintern): New function to take the place of the old
5463 scm_sysintern. It uses the current toplevel lookup closure to give
5464 the symbol its value. This is a temporary hack to put packages
5465 like gtcltk into their own module.
5466 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5467 us whether `scm_top_level_lookup_closure_var' has been initialized
5469 * eval.c (scm_init_eval): Set it.
5471 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5473 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5474 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5476 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5478 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5479 scm_sys_dup): deleted: FD capability will be added to other
5481 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5482 scm_fd_free, fd_smob, scm_intern_fd.
5483 (scm_open): renamed from scm_sys_open. Return a port instead of
5484 an FD object. Make the mode argument optional.
5485 (scm_sys_create): deleted, it's just a special case of open.
5486 (scm_init_filesys): move interning of constants O_CREAT etc.,
5487 here (were previously using SCM_CONST_LONG macro).
5488 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5490 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5491 include "fports.h" and <stdio.h>
5492 (scm_stat, scm_select): don't support FD objects.
5494 * error.h: adjust scm_syserror_msg prototype.
5495 * error.c (scm_syserror_msg): take an extra argument for errno.
5496 Using the global value didn't always work, since it could be
5497 reset by procedure calls in the message or args arguments.
5499 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5500 I don't understand why the check was there (and what about the
5503 * strop.c (scm_string_copy): allow shared substrings to be copied.
5505 * unif.h: corresponding change to prototypes.
5506 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5507 recognize two new optional arguments: offset and length. Allow
5508 the port argument to be an integer (file descriptor, for scsh).
5509 Include <unistd.h> for "read" prototype.
5511 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5513 * socket.c: don't include filesys.h.
5515 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5517 * Makefile.am: add AWK=@AWK@ (?)
5519 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5521 Add a rule to generate errnos.c from errnos.
5522 * error.c (scm_init_error): include errnos.c.
5523 * errnos_cnvt.awk: new file, converts the list of errno codes to
5525 * errnos_get.c: new file.
5526 * errnos.default: new file, contains errnos to try if they can't
5527 be extracted from errno.h.
5528 * configure.in: if using GCC, try and extract errno codes from
5532 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5534 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5535 * Makefile.am: Made libguile into a libtool library.
5536 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5537 Set libtool_libs to indicate that libguile is a libtool library.
5538 See guile/ChangeLog for details.
5539 * .cvsignore: ignore "*.lo", the libtool library objects.
5541 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5543 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5544 use htons in getservbyport argument.
5546 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5548 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5549 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5552 * objprop.c (scm_object_property): No need to take the CDR of the
5553 value returned by scm_object_properties, since Aug 20 change.
5555 * configure.in: When checking for struct linger, #include
5556 <sys/types.h> as well as <sys/socket.h>. I've never known
5557 <sys/types.h> to cause any portability problems, and Solaris's
5558 <sys/socket.h> needs it.
5559 * configure: Rebuilt.
5561 I think the Sun compiler has chosen a perverse way to interpret
5562 ANSI declarations combined with K&R definitions. We'll
5563 appease it a little bit. But when it invades France, we fight.
5564 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5565 * print.h (scm_iprlist): Here too.
5566 * numbers.c (scm_divbigdig): Change definition to match
5567 declaration in numbers.h.
5568 * unif.c (scm_makflo): Change definition to match declaration in
5571 * init.c (scm_boot_guile): Don't return the value of
5572 scm_boot_guile_1. This function doesn't return a value;
5573 scm_boot_guile_1 doesn't return a value (or return at all).
5575 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5578 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5579 compile. I have a feeling this function is a bad idea anyway ---
5580 one should always test for features, not systems.
5582 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5583 semicolons. Only pure luck kept this from being noticed earlier.
5585 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5587 * socket.c (scm_recvfrom): Added missing semicolon.
5589 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5591 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5592 the buffer and start and end positions for scsh networking
5595 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5597 * configure.in: Revert previous change to this file; the problem
5598 is due to transient automake weirdness.
5599 * configure: Rebuilt.
5601 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5602 PLUGIN/guile.libs. configure generates the latter from the former.
5603 * Makefile.in: Rebuilt.
5605 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5606 need this if we install scripts, like guile-snarf.
5607 * configure: Rebuilt.
5609 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5611 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5613 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5615 * socket.c (scm_addr_vector): fix faulty scm_listify.
5617 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5619 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5620 style block comment is no longer considered an error.
5622 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5624 * PLUGIN/guile.libs.in: New file.
5625 * PLUGIN/guile.libs: Removed from repository.
5626 * configure.in: Create PLUGIN/guile.libs from
5627 PLUGIN/guile.libs.in. This is for including additonal libraries
5628 needed for dynamic linking.
5629 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5630 instead of PLUGIN/guile.libs.
5632 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5634 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5636 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5637 occurrences of the given element from the list, not just the
5638 first. This is how the Emacs Lisp functions behave, how the
5639 analogous Common Lisp functions behave, and (I believe) how the
5640 older Maclisp functions worked. I realize that this change may
5641 break code, but it seemed better to break it before the Guile
5644 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5645 Their prototypes were already present in gc.h, but they weren't
5647 (scm_init_storage): Initialize scm_protects.
5648 * root.c (scm_protects): New element of scm_sys_protects.
5650 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5652 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5654 * libguile.h: Added #include "libguile/net_db.h".
5656 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5657 30 change. That file is only meant for communication between the
5658 configuration process and load.c. If code linked against libguile
5659 wants to get at the paths mentioned in libpath.h, it can call
5660 functions declared in load.h.
5662 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5664 * libguile.h: Removed #include "libguile/fdsocket.h"
5666 * net_db.c: Added #include <sys/socket.h>.
5668 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5670 * filesys.c (scm_input_waiting_p): use select in preference to
5671 FIONREAD, since the latter doesn't detect EOF.
5672 Throw error if neither select nor FIONREAD available.
5674 * socket.c (scm_connect): take a port, not a fd object.
5675 (scm_fill_sockaddr): throw an error if fam is not recognised.
5676 (scm_bind): use scm_fill_sockaddr.
5677 (scm_listen): take a port, not a fd object.
5678 (scm_accept): take and return a port. return #f in the car if
5679 address can't be got
5680 (scm_sock_fd_to_port): new procedure.
5681 (scm_socket): use scm_sock_fd_to_port.
5682 (scm_addr_vector): throw error if unrecognised address type.
5683 take an extra argument with the calling procedure name.
5684 (scm_getsockname): take a port. return #f if address can't be got.
5685 (scm_getpeername): take a port. return #f if address can't be got.
5686 (scm_recvfrom): take a port. return #f for address component if can't
5688 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5689 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5691 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5693 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5694 use separate data pointers, to allow them to be designed
5695 independently and reused.
5696 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5697 Renamed from catch_body, catch_handler, and uncaught_throw; made
5699 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5701 (scm_catch): Use the above.
5702 (scm_throw): Don't bother printing a message for an uncaught
5703 throw; we establish a default handler in init.
5704 * throw.h (scm_internal_catch): Prototype updated.
5705 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5707 (struct scm_body_thunk_data): New structure, used as data
5708 argument to scm_body_thunk.
5709 * init.c (struct main_func_closure): New structure, packaging up
5710 the data to pass to the user's main function.
5711 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5712 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5713 scm_internal_catch to establish a catch-all handler, using
5714 scm_handle_by_message. This replaces the special-case code in
5716 (invoke_main_func): Body function for scm_internal_catch; invoke
5717 the user's main function, using the main_func_closure pointer to
5718 decide what to pass it.
5719 * root.c (struct cwdr_body_data): Remove handler_proc member.
5720 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5721 (cwdr_handler): Removed.
5723 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5725 * socket.h (SCM_P): update bind prototype.
5726 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5727 include "feature.h".
5728 (scm_socket): return a port, not a file descriptor object.
5729 include "fports.h" and <unistd.h>
5730 (scm_bind): take a port, not a file descriptor object.
5731 take an extra argument for address args.
5733 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5734 INADDR_NONE, INADDR_LOOPBACK.
5736 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5738 * init.c: include net_db.h and not fdsocket.h.
5739 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5741 * Makefile.am: corresponding changes.
5742 * socket.h: renamed from fdsocket.h, fix names.
5743 * net_db.h: renamed from socket.h, fix names.
5744 * socket.c: renamed from fdsocket.c.
5745 remove _sys from procedure names.
5746 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5747 add "socket" to features list.
5748 * net_db.c: renamed from socket.c.
5749 remove _sys from procedure names.
5750 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5751 add "net-db" to features list.
5752 include "net_db.h". don't include <sys/socket.h> or
5755 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5757 * tags.h (scm_tags): Removed comma at end of last enumerator.
5759 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5761 Don't use GCC extensions to allocate space for debugging frames.
5762 (Here he goes again! Why do we put up with this?!)
5763 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5764 an scm_debug_info structure, not an in-line array of them. Add
5765 'info' member, to say how many vect elements we've used, for eval
5767 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5768 a new variable debug_info_end to mark the end of vect, instead of
5769 the address of the 'info' pointer itself.
5770 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5771 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5772 (SCM_APPLY): Explicitly allocate space for debug.vect.
5773 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5774 * stacks.c: Adjusted for new debug frame structure.
5775 (RELOC_INFO, RELOC_FRAME): New macros.
5776 (stack_depth, read_frames): Use them, and new scm_debug_frame
5777 element 'info', instead of magically knowing that eval frames have
5778 an info pointer sitting after vect.
5779 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5781 (scm_init_stacks): Formatting tweaks.
5783 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5785 Give GCC more control flow information, so it can be sure that
5786 variables aren't used uninitialized.
5787 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5788 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5789 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5790 scm_misc_error): Tell GCC that these functions never return.
5791 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5792 out the field type, call abort if SCM_ASSERT returns, to placate
5794 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5795 scm_wta ever returns. We can't handle this case anyway, and this
5796 gives the optimizer more information.
5797 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5798 scm_wta ever returns.
5800 In some cases, the code is fine, but GCC isn't smart enough to
5801 figure that out; this usually happens when one variable is only
5802 initialized and used when a particular condition holds true, and
5803 we know that condition will never change within a given invocation
5804 of the function. In this case, we simply initialize the variables
5805 to placate the compiler, hopefully to a value which will cause a
5806 crash if it is ever actually used.
5807 * print.c (scm_iprin1): Initialize mw_pos.
5808 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5809 * throw.c (scm_ithrow): Initialize dynpair.
5810 * unif.c (scm_uniform_vector_ref): Initialize cra.
5811 * struct.c (init_struct): Initialize prot.
5812 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5814 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5815 if EXPR contains no expressions.
5817 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5819 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5820 cause an infinite loop (???). So much for the algebraic
5821 equivalency of variable-sized arrays and alloca...
5823 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5825 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5826 a SCM boolean, not a C boolean.
5828 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5830 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5831 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5832 rules for raising scm_mtrigger. Previously, unfortunate but not
5833 unlikely circumstances could result in almost constant invokation
5834 of the gc. Now, this situations should be less likely, but they
5835 are not prevented completely.
5837 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5839 * numbers.c (scm_fuck): Procedure removed; looks like old test
5841 * numbers.h: Prototype removed.
5843 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5845 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5846 array to a pointer, to match my Nov 21 change in eval.c.
5848 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5850 * libguile.h: Added #include "libguile/backtrace.h", #include
5851 "libguile/stacks.h".
5853 * strings.c (scm_string scm_make_string scm_string_ref
5854 scm_string_set_x scm_string_equal_p scm_string_append):
5855 Bugfix according to scm patch from Aubrey Jaffer:
5856 Corrected long-standing
5857 (not (eqv? (integer->char 128)
5858 (string-ref (make-string 1 (integer->char 128)) 0)))
5859 bug found by John Kozak <jk@noontide.demon.co.uk>.
5861 * strports.c, strports.h: Make scm_eval_0str return the value of
5862 the last expression evaluated (previously, it returned void).
5864 * strports.c, strports.h: New function: scm_read_0str. Does what
5867 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5869 * simpos.c (scm_getenv): return #f if string can't be found in the
5870 environment instead of throwing an exception, for compatibility
5871 with numerous other systems.
5873 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
5875 * Makefile.am (.c.x): Use guile-snarf.
5876 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
5878 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
5880 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5882 * backtrace.c (scm_display_error_message): Made non-static, and
5883 renamed from display_error_message.
5884 * backtrace.h (scm_display_error_message): Added extern decl.
5885 * throw.c (uncaught_throw): Use it to display the error message.
5887 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
5889 * inet_aton.c: Use #if 0, not #ifdef 0.
5891 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
5893 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
5894 to convert the returned value.
5895 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
5896 the offset argument.
5898 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5900 Add new interface to catch/throw, usable from C as well as
5902 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
5903 (scm_internal_catch): New function, replaces...
5904 (scm_catch_apply): Deleted.
5905 * throw.c (scm_catch_apply): Deleted; replaced with a more general
5906 mechanism which is a bit more code, but can be used nicely from C
5907 and implement the Scheme semantics as well.
5908 (scm_internal_catch): This is the replacement; it's named after
5909 the analogous function in Emacs.
5910 (scm_catch): Reimplemented in terms of the above.
5911 (struct catch_body_data, catch_body, catch_handler): New
5912 functions, used by scm_catch.
5913 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
5914 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
5915 support for new cwdr.
5917 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
5920 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
5922 * acconfig.h: Added DYNAMIC_LINKING symbol.
5923 * configure.in: Add option and checks for dynamic linking.
5924 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
5925 dynl.h: New files for dynamic linking support.
5926 * Makefile.am (libguile_a_SOURCES):
5928 (modinclude_HEADERS): Added "dynl.h".
5929 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
5931 * init.c (scm_boot_guile_1): Call
5932 scm_init_dynamic_linking to initialize dynamic linking support.
5934 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
5936 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
5937 (as we Schemers say). It needs to be global, so that I can tweak
5938 it for the proper operation of unexec.
5939 (scm_boot_guile_1_live): New variable, see above.
5941 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
5943 * guile-snarf.sh: Removed.
5944 * PLUGIN/guile.libs: Added dependency for -lm.
5945 * acinclude.m4: Renamed from aclocal.m4.
5946 * PLUGIN/greet: Removed.
5947 * Makefile.am, aclocal.m4: New files.
5948 * configure.in: Updated for Automake.
5950 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
5952 * eval.c (scm_definedp): Use top_level_lookup_closure_var
5953 and not top_level_lookup_thunk_var.
5955 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
5957 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
5959 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
5961 * eval.c (scm_definedp): Incompatibly changed to be a builtin
5962 Scheme function, instead of syntax. Single argument is now a
5965 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5967 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
5968 scm_ra_divide): Properly terminate statements passed as arguments
5969 to IVDEP macros. (Thanks to Bernard Urban.)
5971 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
5972 with non-constant sizes. (Thanks to Bernard Urban.)
5974 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5976 It's an "eval closure", not an "eval thunk." A thunk is a
5977 function of no arguments.
5978 * root.h (struct scm_root_state): Renamed
5979 top_level_lookup_closure_var from top_level_lookup_thunk_var.
5980 (scm_top_level_lookup_closure_var): Renamed from
5981 scm_top_level_lookup_thunk_var.
5982 * root.c (mark_root): Uses changed.
5983 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
5984 * init.c (scm_start_stack): Uses changed.
5985 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
5986 Change scheme-visible name to *top-level-lookup-closure* from
5987 *top-level-lookup-thunk*.
5989 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
5991 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
5992 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
5994 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
5996 * gc.c (struct scm_heap_seg_data): Doc fixes.
5998 * gc.c (scm_gc_sweep): Empty all segments' freelists before
5999 sweeping. Then, prepend each segment's free cells to its
6000 freelist, rather than wiping out the old value. (Thanks to Marius
6003 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6004 scm_check_freelist, scm_debug_newcell): New functions and
6005 variables, for debugging freelist problems.
6006 * pairs.h (SCM_NEWCELL): New debugging version added.
6007 * gc.h (scm_debug_newcell): Added extern declaration, used by
6008 debugging version of SCM_NEWCELL.
6010 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6012 On some systems <libc.h> conflicts with <unistd.h>, and should not
6013 be #included at all.
6014 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6015 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6016 * configure.in: Call it.
6017 * posix.c, filesys.c: Use its results to decide whether or not to
6019 * configure, scmconfig.h.in: Rebuilt with autoconf and
6022 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6024 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6025 pointer to the stdio stream before calling scm_setbuf0, so the
6026 latter will be able to retrieve it. I'm surprised this didn't
6027 segfault earlier. (Thanks to Christopher Lee.)
6029 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6031 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6034 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6036 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6037 number of stack narrowing specifier pairs. The first specifier in
6038 a pair controls inner border, the second the outer border. A
6039 number means cut that number of frames, a procedure object means
6040 cut until that object is found in operator position in a frame.
6042 * root.c (cwdr): Bugfix.
6044 * read.c: Recording of positions disabled by default.
6046 * procs.c (scm_closure_p): New function.
6048 * posix.c (scm_tmpnam): New function.
6050 * load.c: Added #include "throw.h".
6051 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6054 * load.c, load.h (scm_read_and_eval_x): New function.
6056 * eval.c: Renamed debug option "deval" to "debug".
6058 (scm_eval_x): `eval!' is no longer accessible from the scheme
6059 level. Motivation: We can't allow operations which introduce
6060 glocs into the scheme level. Guile's type system can't handle
6061 these as data. Use `eval' or `read-and-eval!' as replacement.
6063 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6064 SCM_CONSP since this is a macro!; Set vframe.prev to
6065 scm_last_debug_frame instead of 0. In this way we can look
6066 "above" the virtual start stack frame if we wish.
6067 (scm_debug_hang): New function: Useful for debugging Guile in
6068 certain tricky situations. Will probably be removed later...
6070 * debug.h: Changed semantics of debug option "backtrace". This
6071 option now only indicates whether we want automatic backtrace at
6074 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6076 * ports.c: #include "filesys.h"
6077 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6079 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6080 Motivation: This is system specific code which is related to file
6081 I/O. It also may use select. Added code by Gary Houston to
6082 detect presence of character in stdio buffers.
6084 * libguile.h: #include "libguile/libpath.h"
6086 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6087 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6088 SCM_SITE_DIR; Install libpath.h among the other include files.
6090 * load.c, load.h (scm_sys_package_data_dir): New function.
6092 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6094 * stacks.h: Bugfix: Don't use tail-array length field as stack
6095 length field! This screwed GC.
6097 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6099 * _scm.h: Added #ifndef around definition of macros min and max.
6101 * __scm.h: Added hooks for threads to plugin to in ints protection
6102 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6103 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6104 the main code in these macros duplicated and spread over multiple
6105 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6106 SCM_THREAD_SWITCHING_CODE.
6108 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6110 * snarf.h: New file.
6111 * guile-snarf.sh: New file.
6112 * Makefile.in (inner_h_files): Added snarf.h
6113 (ancillary, install, uninstall, distclean): Added actions for
6115 (.c.x): Use guile-snarf.
6116 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6117 (gen_c_files): Note that these depend on guile-snarf.
6118 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6119 now in "snarf.h". Added #include "snarf.h" to get them.
6120 * libguile.h: Added #include "snarf.h".
6121 (Patches applied and tweaked by Jim Blandy.)
6123 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6125 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6126 standards suggest against providing prototypes for system
6127 functions. Thanks to Greg Troxel.
6129 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6131 * strports.c (scm_eval_0str): New function.
6132 #include "read.h", to get prototype for scm_read.
6133 * Makefile.in (strports.o): Update dependencies.
6134 * strports.h: New prototype.
6136 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6137 scheme name from "int?" to "integer?". It seems to do the job.
6138 * numbers.h: Rename prototype too.
6139 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6142 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6143 scm_num_eq_p): Rename these according to R4RS conventions: call
6144 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6145 to making libguile R4RS compliant without ice-9...
6147 * load.c (scm_sys_search_load_path): Search for files under all
6148 extensions listed in the %load-extensions variable. If FILENAME
6149 is absolute, return it unchanged, without searching the load path.
6150 (scm_loc_load_extensions): New variable, pointing to
6151 %load-extensions' value cell.
6152 (scm_init_load): Initialize it, and the value it points to.
6153 (scm_primitive_load_path): Improve error reporting.
6155 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6156 of new Scheme variable %load-hook.
6157 (scm_primitive_load): Apply %load-hook to filename.
6159 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6161 * configure.in: add tests for figuring out whether buffered data
6162 is available in a FILE structure, which is needed by char-ready.
6164 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6167 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6168 exceptions using misc_error instead of syserror. It seems a bit
6169 odd to throw an exception if a string can't be found in the
6170 environment, but it's consistent with open-file, stat etc.
6171 (simpos.h): remove sys_ from getenv.
6173 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6174 occurs, throw an error instead of returning errno. Return value
6176 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6178 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6180 * filesys.c (scm_stat2scm): derive file type and permissions from
6181 the stat mode and append them to the returned vector.
6182 There isn't much overhead in doing this and it avoids the need to
6183 work with S_IRUSR et al. in Scheme.
6184 Define symbols scm_sym_regular etc.
6185 (scm_init_filesys): don't intern S_IRUSR etc.
6187 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6188 and s_primitive_load_path.
6190 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6192 * error.h: don't declare error symbols. prototype for scm_misc_error.
6194 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6197 * error.c: use SCM_SYMBOL to set up error keys.
6198 scm_misc_error: new procedure.
6200 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6202 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6203 between `#!' and `!#' is ignored.
6204 (skip_scsh_block_comment): New function.
6206 * feature.c (scm_set_program_arguments): New argument, FIRST.
6207 * feature.h: Update prototype.
6208 * init.c (scm_boot_guile_1): Pass new argument to
6209 scm_set_program_arguments.
6211 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6213 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6214 (scm_boot_guile): Call scm_set_program_arguments here, later than
6215 the old initialization.
6217 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6218 initialization procedure.
6219 - Delete in, out, err arguments; there are other perfectly good
6220 ways to override these when desired.
6221 - Delete result argument; this function shouldn't ever return.
6222 - Rename init_func argument to main_func, for less confusion.
6223 - Delete boot_cmd argument; main_func is more general.
6224 -Add 'closure' argument, to help people pass data to main_func
6225 without resorting to global variables.
6226 - Abort if reentered; don't bother returning an error code.
6227 - Call scm_init_standard_ports to set up the default/current
6228 standard ports; no need to pass them to scm_start_stack.
6229 - Remove code to evaluate the boot_cmd, and start the repl; let
6230 the user do something like that in main_func if they want.
6231 - Remove code to package up a return value; main_func can do any
6233 - Call exit (0), instead of returning.
6234 (scm_start_stack): Don't initialize the I/O ports here; that's
6235 weird. Delete in, out, err arguments. Move guts to
6236 scm_init_standard_ports, scm_stdio_to_port.
6237 (scm_init_standard_ports): New function, to set up current and
6238 default standard ports.
6239 (scm_start_stack, scm_restart_stack): Make these static.
6240 * init.h (scm_boot_guile): Adjust declaration.
6241 (scm_start_stack, scm_restart_stack): Remove externally
6242 visible declarations for these.
6243 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6245 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6246 written out several times in scm_start_stack.
6247 * fports.h: New declaration for the above.
6249 * feature.c (scm_set_program_arguments): New function.
6250 * feature.h: New declaration for the above.
6252 * ports.c: Formatting tweak.
6254 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6256 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6257 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6258 for obtaining the address of a car or cdr field. Motivation:
6259 &SCM_CXR make assumptions about the internal structure of the
6262 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6263 Motivation: see SCM_CXRLOC.
6265 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6266 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6267 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6268 Motivation: Safer use. Some other macros are defined in terms of
6269 these operations. If these are defined using the SCM_SETCXR
6270 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6271 to inefficiency and an <e1> with side-effects could potentially
6272 break. Also, these particular operations are heavily utilized in
6273 the garbage collector. In unoptimized code there will be a
6276 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6277 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6278 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6279 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6280 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6281 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6282 vports.c: Cleaned up use of pairs: Don't make any special
6283 assumptions about the internal structure of selectors and
6284 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6285 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6286 (Among other things, this change makes it easier to build Guile
6287 with certain compilers which have problems with casted lvalues.)
6289 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6291 * stacks.c: Improve selection of relevant stack frames when making
6292 a stack object. Introduce one level of indirection in the stack
6293 object to make it possible to "narrow" to a certain region of the
6294 stack. This facilitates making use of more clever algorithms (not
6295 implemented) for selecting relevant frames and gives a cleaner
6296 design since selection of frames can be done independently of
6297 extraction of frames from the real stack.
6298 (scm_stack_id): Also take #t as argument which means look at
6301 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6302 Turn n_tail into an integer directly representing current number
6303 of frames in stack. Add field tail.
6305 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6307 * debug.c (scm_make_memoized): Made it available at scheme level.
6308 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6309 SCM_NIMP before applying heavier predicates in argument checking.
6310 (scm_local_eval): Also take memoized object as argument.
6312 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6313 aren't created with zero length, but should such a strange
6314 creature suddenly turn up...
6316 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6318 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6319 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6321 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6323 * variable.c (scm_make_variable): Make the name hint optional, as
6325 (anonymous_variable_sym): Renamed from variable_sym. All uses
6328 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6329 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6330 of scm_primitive_load_path was also changed to
6331 "primitive-load-path", from "%try-load-path". Callers changed.
6332 We'd like to respect the convention that a function named
6333 "try-mumble" should behave just like the function called "mumble",
6334 but return #f instead of signalling some error.
6335 * load.h: Rename prototypes.
6337 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6339 * print.c (make_print_state, grow_print_state), print.h: Modified
6340 the print state representation: Don't use a tail array for
6341 recording of circular references. Resizing of the print state
6342 structure invalidates the print state pointer. To avoid passing
6343 around an indirect print state reference to all printing
6344 functions, we instead let the print state reference a resizable
6347 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6349 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6350 Don't crash when passed an improper list terminated by a
6351 non-immediate value.
6353 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6355 Allocate data for structures on an eight-byte boundary, as
6356 required by the tagging system.
6357 * struct.c (alloc_struct): New function.
6358 (scm_make_struct, scm_make_vtable_vtable): Call it.
6359 * struct.h (scm_struct_n_extra_words): Bump to 3.
6360 (scm_struct_i_ptr): New "field".
6361 * gc.c (scm_gc_sweep): When we need to free the data, use the
6362 information stored by alloc_struct to find the beginning of the
6363 block allocated to the structure, so we can free it.
6365 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6367 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6370 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6371 (scm_debug_info): New member: id.
6373 * stacks.c: Stacks are now represented as structs; Stacks have an
6374 id given to them by `start-stack'.
6375 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6377 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6378 Changed stack representation.
6380 * debug.c (scm_procedure_name): Try procedure property `name' for
6381 compiled closures aswell.
6383 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6385 * eval.c: scm_i_name moved to gsubr.c
6386 (scm_m_define): Record names of all kinds of procedure
6387 objects. (Earlier, only closures were recorded.)
6389 * procprop.h: Added declaration of scm_i_name.
6391 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6392 (scm_make_gsubr): Record names of compiled closures.
6394 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6396 * debug.c, debug.h: Removed obsolete code.
6398 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6399 stacks.c: Renamed regs --> scm_contregs.
6401 * print.c (scm_free_print_state): Cleanup print state before
6402 returning it to pool. It is better to do it here than in
6403 scm_prin1 since scm_prin1 is called often.
6405 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6406 s_set_source_property_x): Check that first argument is a pair or a
6409 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6410 scm_i_line, scm_i_column and scm_i_breakpoint global.
6412 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6413 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6416 * debug.h: Added debug object smob declaration and macro
6419 * configure.in: Build with backtrace.o and stacks.o if debug
6422 * Makefile.in: Added entries for new files: backtrace.c,
6423 backtrace.h, stacks.c and stacks.h.
6425 * symbols.c (scm_sym2ovcell): Fixed documentation.
6427 * _scm.h (min, max): Added.
6429 * async.c: Moved `min' macro to _scm.h.
6431 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6432 SCM_BACKTRACE_INDENT.
6434 * eval.c: Added new debug options `maxdepth' and `indent'.
6436 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6438 * print.h: Added selector SCM_PRINT_STATE.
6440 * print.c: New functions: scm_make_print_state,
6441 scm_free_print_state.
6443 * print.h: Added declarations for scm_make_print_state,
6444 scm_free_print_state.
6446 * debug.c (scm_m_start_stack): New acro.
6448 * debug.h: Small cleanup.
6450 * init.c (scm_boot_guile_1): Moved scm_init_debug below

6473 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
6474 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
6475 declare functions with prototypes. (Patch thanks to Marius
6478 More prototype-related changes from Marius Vollmer:
6479 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6480 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6481 * ports.h (ptobfuns): Added prototypes. This means some casting in
6483 * fports.c: Added casts for initializations, since the functions
6484 are defined to take FILE * as their stream argument, not SCM.
6485 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6486 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6487 to `char *str_data' to conform to prototype.
6489 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6491 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6493 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6495 * stime.c, stime.h: use SCM_P method.
6497 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6499 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6500 be given at least two arguments. Insist that lst's last element
6501 be a list, but don't make any requirements of its predecessors.
6503 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6505 * eval.c (scm_nconc2last): Revert last change; there seems to be
6506 other stuff going on here.
6508 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6510 * eval.c (scm_nconc2last): Make sure that each element of lst
6511 (which is a list of argument lists, except for the tail) is a
6512 proper list, i.e., finite and terminated by '().
6514 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6516 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6519 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6520 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6523 * vectors.c (scm_make_vector): Fill vectors with the undefined
6524 value, to help make Guile Scheme code more portable to other
6527 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6528 * symbols.h, tags.h: Doc fixes.
6530 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6532 * async.c (scm_take_signal): Doc fixes.
6534 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6536 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6537 want to subtract it from the modulus; we just want to leave it
6540 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6542 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6545 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6547 * throw.c (scm_catch_apply): Finished implementation of
6550 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6552 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6554 (scm_init_filesys): set "i/o-extensions" feature.
6557 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6559 * Makefile.in (root.o): Correct dependencies.
6561 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6563 * Makefile.in: Added dependency entry for root.o.
6565 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6566 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6568 * init.c (scm_start_stack): Set initial root continuation number
6571 * procs.c: New function: scm_thunk_p.
6573 * procs.h: Added declarations of scm_thunk_p.
6575 * root.c: Renamed `call-with-new-root' -->
6576 `call-with-dynamic-root'.
6577 (cwdr): Removed allocation of new root state. This should be done
6578 separately by use of scm_make_root.
6579 (scm_apply_with_dynamic_root): New function: Does what it
6580 sounds like. Needed when spawning threads.
6582 * root.h: Added member last_debug_frame to root state.
6583 Added #include "libguile/debug.h"
6585 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6586 arguments. The motivation is that code in root.c needs catch
6587 functionality, and we want to avoid code duplication.
6588 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6589 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6590 handlers that run without popping the stack into the dynwind
6593 * throw.h: Added prototypes for scm_catch_apply and
6596 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6598 * root.h (scm_root, scm_set_root): Decouple thread support details
6599 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6600 SCM_SET_THREAD_LOCAL_DATA.
6602 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6603 and tortoise scanning loop.
6605 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6607 * Makefile.in: Rebuild dependencies.
6609 * libguile.h: #include "libguile/print.h" before "smob.h", since
6610 the latter uses the print_state structure.
6612 * throw.c (scm_ithrow): Use the correct variable when checking to
6613 see if a given element of scm_dynwinds is a valid catch.
6615 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6616 structure, abort; don't just silently ignore the garbage.
6618 * _scm.h: #include "print.h" here, since it seems to be used just
6620 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6621 strports.c, unif.h: Don't #include "print.h".
6623 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6625 * feature.h (scm_loc_features): Removed external declaration.
6626 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6628 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6630 * feature.c (scm_init_feature): Added threads feature (needs to be
6631 initialized here, since features doesn't exist when
6632 scm_init_threads is called).
6634 * libguile.h: Added #include "libguile/../threads/threads.h".
6635 (This is a kludge to get thread support working. This should be
6638 * configure.in, acconfig.h: Added flags for thread support.
6640 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6643 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6644 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6647 * _scm.h: Added conditional #include "threads.h"
6649 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6650 SCM_THREADS_SWITCHING_CODE.
6652 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6653 allocate the basic dynamic root object.
6654 (scm_boot_guile): Added call to scm_init_root.
6656 * root.c, root.h: Added root smob.
6657 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6658 functions: Implements dynamic roots mostly according to spec in
6659 SCM manual. Main difference is that the second argument is a
6660 throw handler rather than an error "thunk".
6662 * root.h: Added declaration of scm_init_root.
6664 * root.c: Added #include "genio.h", #include "smob.h", #include
6665 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6667 (scm_init_root): Added #include "root.x".
6669 * throw.c: Added #include "stackchk.h"
6670 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6671 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6672 can be used in scm_call_with_new_root; Added reenabling of stack
6673 checking when catching a throw.
6675 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6677 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6679 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6680 element is not found, as per R4RS.
6682 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6684 * list.c: Doc fixes throughout.
6686 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6688 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6689 declare the char * to be const. Avoids a warning in rgx.c.
6691 * ports.h: spelling fix.
6693 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6696 * load.c (scm_sys_try_load_path): throw an error if file not found
6697 (like it says it in NEWS).
6699 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6701 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6702 PROPS slot to '(), not #f; it's an empty alist.
6704 * throw.h, throw.c: Use SCM_P instead of #if hair.
6706 Remove special support for uncaught throws; see throw.c for
6708 * throw.c (uncaught_throw): New function.
6709 (scm_ithrow): Call uncaught_throw if we don't find a throw
6710 target; don't mess with scm_bad_throw_vcell.
6711 (scm_bad_throw_vcell): Variable deleted.
6712 (scm_init_throw): Don't initialize it.
6714 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6717 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6719 * numbers.c (scm_istr2int): If the number is short (as most
6720 numbers are), just call scm_small_istr2int to deal with it.
6721 (scm_small_istr2int): New function, created by un-#ifdefing the
6722 non-bignum version of scm_istr2int and renaming it.
6724 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6726 * load.c (scm_sys_try_load): don't check whether value returned
6727 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6728 Change the Scheme name from %try-load to primitive-load.
6730 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6731 Can avoid passing a message, allowing it to be derived in the
6732 error handler (e.g., if we want to throw to the key both from
6735 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6737 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6738 references now have a new appearance which is more compact and
6739 also gives a clue about what the target of the reference is.
6740 By setting parameters in the print state, more fancy printing can
6741 be achieved. This is used by the (not yet commited) backtrace
6744 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6746 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6749 * print.c: Added #include "struct.h". Removed function
6752 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6753 scm_iprin1. Removed prototype for scm_prlist.
6755 * arbiters.c (prinarb),
6756 async.c (print_async),
6757 debug.c (prindebugobj, prinmemoized),
6758 eval.c (prinprom, prinmacro),
6759 filesys.c (scm_fd_print, scm_dir_print),
6761 mallocs.c (prinmalloc),
6762 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6763 smob.h (scm_smobfuns),
6764 srcprop.c (prinsrcprops),
6766 unif.c, unif.h (scm_raprin1, rapr1),
6767 variable.c (prin_var): Changed argument `int writing' to
6768 `scm_print_state *pstate'.
6770 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6771 that it will be called before scm_init_print.
6773 * print.c (scm_prin1): Print states are now allocated when calling
6774 scm_prin1 and then passed around to all printing functions as an
6775 argument. A cache `print_state_pool' enables reuse of print
6777 (scm_make_print_state): New function.
6778 (scm_iprin1): Adaption to print states.
6779 (scm_iprlist): An initial "hare and tortoise" scan brings down
6780 time complexity to O (depth * N). (Better time complexity will be
6781 achieved when the printing code is completely rewritten.)
6783 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6785 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6786 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6787 it gets done whether or not the cache variable has a value.
6789 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6791 Distinguish #f and ().
6792 * __scm.h: #undef SICP.
6793 * pairs.h (SCM_EOL): Delete this definition, equating it with
6795 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6796 the value it used to have. Doc fixes, too.
6798 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6800 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6801 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6802 Lord's implementation of structs, allowing for tail arrays as
6803 described in the manual. Also fixed some bugs. (Both the interface
6804 and the implementation should be improved.)
6806 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6808 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6809 People who whish to see the source can do `(print-enable 'source)'.
6810 Removed #ifdef DEBUG_EXTENSIONS.
6812 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6814 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6815 integer (assuming for now accepting an integer is a good thing).
6817 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6818 %S will be used instead for write'ing arguments.
6820 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6821 asserts. fix a few other asserts.
6822 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6823 scm_uniform_vector_ref, scm_array_set_x,
6824 scm_dimensions_to_unform_array): change args in
6825 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6826 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6827 scm_substring_fill_x): likewise.
6828 gsubr.c (scm_gsubr_apply): likewise.
6829 eval.c (SCM_APPLY): likewise.
6831 * eval.c (4 places): replace scm_everr with lgh_error or
6834 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6835 scm_memory_error): new procedures.
6836 scm_everr: deleted. can use scm_wta, dropping first two args.
6837 scm_error: convert NULL subr to SCM_BOOL_F.
6839 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6842 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6845 * error.c, error.h: new error keys: scm_arg_type_key,
6846 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6848 scm_wta: reimplement using lgh_error instead of scm_everr.
6850 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6852 * gdbint.c: scm_lread now has one more argument.
6854 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6855 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6856 loading source from non-file ports, which, e. g., happens when
6857 using the Emacs interface).
6859 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6862 * read.c: Added code for recording of positions of source code
6863 expressions; New functions: recsexpr, scm_lreadrecparen;
6864 _scm_make_srcprops --> scm_make_srcprops
6865 (scm_flush_ws): Removed updating of positions counters. This work
6866 is already done by scm_gen_getc
6868 * read.h: Added prototype for scm_lreadrecparen

6880 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
6881 --> scm_make_srcprops
6883 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,

6885 function calls in the definition of the whash access macros.
6887 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
6889 * init.c (scm_boot_guile): Add level of indirection to
6890 scm_boot_guile_1() to ensure that stack base pointer is properly
6891 initialized. There was no guarantee that variable i was the
6892 highest/lowest variable on stack (i.e. the call frame of
6893 scm_boot_guile was not completely protected from gc).
6895 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
6897 * ports.h (scm_port_table): put back file_name, it will be used to
6898 support debugging. Undo related changes in fports.c, ioext.c,
6901 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6903 * ports.h (scm_port_table): remove file_name member for now, it seems
6905 * fports.c (scm_open_file): don't set file_name in PTAB.
6906 (prinfport): don't use file_name in PTAB.
6907 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
6908 * ports.c (scm_add_to_port_table): don't intialize file_name.
6909 (scm_port_file_name): remove for now.
6910 * gc.c (scm_gc_mark): don't mark PTAB file_name.
6912 * fports.h (scm_mkfile): prototype deleted.
6913 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
6915 * debug.c, unif.c: use scm_out_of_range instead of
6916 wta for range errors (ASSERT still needs work).
6918 * error.c, error.h (scm_out_of_range): new procedure.
6920 * error.c, error.h (scm_out_of_range_key): new key.
6922 * posix.c (scm_sync): #else was missing.
6924 * error.c, error.h: append _key to names scm_num_overflow and
6927 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
6928 of consing an empty list.
6929 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
6930 of macros, saves code and string space.
6931 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
6932 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
6933 lower case. Rename scm_syserror_m to scm_syserror_msg.
6934 error.h: prototypes for new procedures.
6936 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
6938 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
6940 * error.c, error.h: setup scm_num_overflow key.
6942 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
6943 Remove definition of SCM_OVSCM_FLOW.
6945 * fports.c (scm_open_file): use SCM_SYSERROR_M.
6947 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
6948 explicit message and args.
6950 * error.c, error.h, __scm.h: change system_error_sym to
6953 * error.c (system_error_sym): remove leading %% from the Scheme name
6956 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
6958 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6960 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
6961 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
6962 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
6963 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
6964 renamed. (These were introduced by unsupervised name
6967 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6969 * print.c: Added code for detection of circular references during
6970 printing. (init_ref_stack, grow_ref_stack): New functions. Added
6971 a hook for printing of closures (accessible via print options).
6972 This leads to a split of calls to scm_iprin1 into two classes:
6973 elementary print operations (e. g. the code which prints a smob)
6974 still use scm_iprin1 while top level calls (like scm_display) use
6975 scm_prin1. scm_prin1 begins by clearing the data structure used
6976 to record reference information.
6978 * print.h: Added declarations of scm_prin1 and scm_prlist.
6980 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
6982 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
6984 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
6986 * error.c (err_head): scm_iprin1 --> scm_prin1
6988 * debug.c: Adjusted header comment.
6992 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6994 * strerror.c: Doc fix.
6996 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6998 * gdbint.c (gdb_read): Now possible to run during GC.
6999 (unmark_port, remark_port): New functions.
7001 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7003 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7004 of allocating a new string object. Also, increase size by
7005 the factor 2 instead of 1.5.
7007 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7009 * __scm.h (SCM_P): Corrected to run under traditional C.
7011 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7014 * async.c: Calls to scm_sysintern corrected.
7016 * async.h (scm_async_clock): Redundant declaration removed.
7018 * continuations.c (scm_dynthrow): Redundant declaration removed.
7020 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7021 Definition typos corrected.
7023 * debug.h: Missing declarations of functions in debug.c added
7026 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7027 Missing declarations to functions in eval.c added.
7029 * filesys.c: Possibly uninitialized variable rv.
7031 * gc.h (scm_object_addr, scm_unhash_name): Missing
7032 declarations of functions defined in gc.c added.
7034 * genio.c: Possible typos str_data -> wstr_data. ???
7036 * genio.c: Possibly unintended shadowing of local variable
7037 `int c' (gotos out of scope of inner `c'). ???
7039 * init.c: Uninitialized `SCM last' may be used.
7041 * ioext.h: (scm_sys_isatty_p): Typo.
7043 * list.h (scm_list_head): Missing prototype for function in
7046 * numbers.c (scm_two_doubles): Changed from extern to static
7047 (is used only within numbers.c).
7049 * numbers.h: Repeated declarations removed.
7051 * ports.h (scm_close_all_ports_except): Declaration for the
7052 function defined in ports.c added.
7054 * posix.h: Missing declarations added.
7056 * procs.h (scm_make_subr_opt): Missing declaration added.
7058 * socket.h (scm_sys_gethost): Missing declaration added.
7060 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7062 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7063 Missing declarations added.
7065 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7067 * struct.c: Uninitialized variable `SCM answer' may be used.
7069 * unif.c (l2ra): Declaration prototype.
7071 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7072 defined in ramap.c).
7074 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7075 Redundant declarations removed (they are in ramap.h).
7077 * variable.h (scm_make_udvariable,
7078 scm_make_undefined_variable): Declaration corrected to
7079 correspond variable.c.
7081 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7082 Missing declarations added.
7084 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7086 * Makefile.in (distclean): Don't forget to delete fd.h.
7088 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7090 * fd.h.in, tags.h: Trivial cleanups.
7092 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7093 marksweep.h just declared functions from gc.c.
7094 * gc.h, libguile.h: Don't #include "marksweep.h".
7095 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7096 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7097 dependencies updated.
7099 * libguile.h: Don't #include "files.h"; it's been deleted.
7101 * files.c (scm_sys_delete_file): Moved to filesys.c.
7102 File is now empty; deleted.
7104 * filesys.c: scm_sys_delete_file is now here. Remove
7105 #if's; they seem to rely on remnants of an old portability
7106 regimen. If the problems come up again, solve them properly,
7107 using autoconf. Specifically: Don't test M_SYSV, and #define
7108 remove to be unlink if it's #defined; don't use remove just
7109 because HAVE_STDC_HEADERS is #defined.
7110 * filesys.h: Add declarations for scm_sys_delete_file.
7111 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7112 files.o, files.h, files.c, and files.x.
7113 * init.c: Don't #include "files.h", and don't call scm_init_files.
7115 Use SCM_P instead of PROTO; the latter intrudes on the user's
7117 * params.h: Deleted; definition of SCM_P moved to...
7118 * __scm.h: ... here, where it replaces PROTO macro.
7119 * libguile.h, smob.h: Don't #include "params.h".
7120 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7121 smob.h: Fix prototypes accordingly.
7122 * Makefile.in: Update dependencies.
7123 (inner_h_files): Remove params.h.
7125 * gc.c: #include "gc.h"; every module should include its header,
7126 to let the compiler cross-check the declarations against the
7129 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7130 simpos.h: #include "libguile/__scm.h".
7132 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7134 * init.c: Don't forget to #include smob.h and init.h.
7135 * Makefile.in: Dependencies updated.
7137 * smob.h: Use PROTO instead of #if __STDC__.
7139 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7141 * __scm.h: Doc fixes.
7143 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7144 <angles>; this allows `make depends' to work properly.
7146 * libguile.h: #include smob.h and pairs.h before the others; they
7147 define typedefs used by other headers.
7149 C files should #include only the header files they need, not
7150 libguile.h (which #includes all the header files); the pointless
7151 recompilation was wasting my time.
7152 * Makefile.in (all .o dependency lists): Regenerated.
7153 * libguile.h: Don't try to get a definition for size_t here...
7154 * __scm.h: Do it here.
7155 * _scm.h: Since this is the internal libguile header, put things
7156 here that all (or a majority) of the libguile files will want.
7157 Don't #include <libguile.h> here; that generates dependencies on
7158 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7159 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",

7272 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7273 don't rely on archaic C default type rules.
7275 * fports.h: #include "libguile/ports.h", since you need that in
7276 order to parse this.
7278 * genio.h: #include "libguile/print.h", because you need that to
7279 parse this; don't bother #including "ports.h", since print.h gets
7282 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7284 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7285 this; it's now a reference to an element of *scm_root.
7287 * debug.h: Don't #include "options.h"; the compiler won't be able
7288 to find that once the headers are installed; instead, #include
7289 "libguile/options.h".
7290 * gc.h: Same, with marksweep.h.
7291 * mbstrings.h: Same, with symbols.h.
7292 * scmhob.h: Same, with _scm.h.
7293 * smob.h: Same, with params.h.
7295 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7296 C files; there's no need for this, and it forces recompilations
7299 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7301 * error.c (scm_error): declare scm_error_callback.
7303 * error.h: prototype for scm_error_callback.
7305 * __scm.h: define lgh_error.
7306 (SCM_SYSERROR): redefine using lgh_error.
7308 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7310 * error.c (scm_error): new procedure.
7312 * error.h: prototype for scm_error.
7314 * Makefile.in (install): install scmconfig.h from the current
7315 directory, not $(srcdir).
7317 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7319 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7320 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7321 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7322 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7323 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7324 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7325 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7326 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7327 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7328 vports.h, weaks.h: #include "libguile/__scm.h", not
7329 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7330 dependencies are within libguile properly.
7332 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7334 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7335 when scmconfig.h doesn't exist.
7337 * load.c (scm_sys_try_load): Correct spelling.
7339 * feature.c (scm_loc_features): Make this static.
7341 * Makefile.in (libpath.h): Omit trailing slash from path. We
7342 shouldn't require it of users, so why put it here?
7344 Move code to initialize and search %load-path from ice-9 to C
7345 code, so we can use the load-path to find the ice-9 boot code;
7346 this makes it easier to run Guile without installing it. See
7347 corresponding changes in guile/Makefile.in.
7348 * feature.c: Move stuff concerned with the load path to load.c.
7349 (scm_compiled_library_path): Deleted.
7350 Don't #include libpath.h here.
7351 * feature.h: Don't mention scm_compiled_library_path.
7352 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7353 <sys/stat.h>, and <unistd.h> (if present).
7354 (R_OK): #define if the system hasn't deigned to.
7355 (scm_loc_load_path): New variable.
7356 (scm_init_load_path, scm_sys_search_load_path,
7357 scm_sys_try_load_path): New functions.
7358 (scm_init_load): Initialize scm_loc_load_path to point to the
7359 value cell of the Scheme %load-path variable.
7360 * load.h: Add declarations for scm_sys_search_load_path,
7361 scm_sys_try_load_path.
7362 * init.c: Call scm_init_load_path.
7363 * Makefile.in (feature.o, load.o): Dependencies updated.
7365 * load.c, load.h: Rewrite using PROTO macro.
7367 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7369 * gc.c (scm_cellp): New function: C predicate to determine if an
7370 SCM value can be regarded as a pointer to a cell on the heap.
7372 * gc.h: Added declaration of scm_cellp.
7374 * gdb_interface.h: New file: The GDB interface header from the GDB
7377 * gdbint.c: New file: GDB interface.
7379 * gdbint.h: New file: GDB interface.
7381 * libguile.h: Added #include <libguile/gdbint.h>.
7383 * init.c (scm_boot_guile): Added scm_init_gdbint.
7385 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7386 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7387 found if object files and source are kept separate).
7389 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7391 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7393 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7395 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7396 TK_SRC_DIR; they're not relevant any more.
7398 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7399 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7401 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7403 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7404 search path, so we can find the <libguile/MUMBLE.h> headers.
7406 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7408 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7409 implicit in the .c.o rule.
7410 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7413 Put the library path in a header file, instead of passing it on
7414 the command line in every compilation.
7415 * Makefile.in (libpath.h): New target.
7416 (feature.o): Depend on libpath.h.
7417 (clean): Delete libpath.h.
7418 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7419 * feature.c: ... #include "libpath.h" here.
7420 * .cvsignore: Ignore libpath.h.
7422 Don't install the unwashed masses of Guile header files in the
7423 main #include path; put most of them in a subdirectory called
7424 'libguile'. This avoids naming conflicts between Guile header
7425 files and system header files (of which there were a few).
7426 * Makefile.in (pkgincludedir): Deleted.
7427 (innerincludedir): New variable; this and $(includedir) are enough.
7428 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7429 (installed_h_files): Divide this up. Now this variable lists
7430 those header files which should go into $(includedir) (i.e. appear
7431 directly in the #include path), and ...
7432 (inner_h_files): ... this new variable says which files appear in
7433 a subdirectory, and are referred to as <libguile/mumble.h>.
7434 (h_files): List them both.
7435 (install): Create innerincludedir, not pkgincludedir. Put
7436 the installed_h_files and inner_h_files in their proper places.
7437 (uninstall): Corresponding changes.
7438 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7439 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7440 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7441 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7442 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7443 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7444 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7445 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7446 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7447 vports.h, weaks.h: Find __scm.h in its new location.
7448 * __scm.h: Find scmconfig.h and tags.h in their new locations
7449 (they're both "inner" files).
7451 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7453 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7455 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7457 * posix.c: Doc fixes.
7459 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7461 * socket.c: Don't include a prototype for inet_aton; just use a
7462 K&R style declaration, to avoid warnings but minimize the chance
7463 of conflicts with the system.
7465 On NextStep, <utime.h> doesn't define struct utime, unless we
7466 #define _POSIX_SOURCE before #including it.
7467 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7468 * acconfig.h: New comment text for above CPP symbol.
7469 * configure.in: Call it.
7470 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7472 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7474 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7475 testing for __EMX__.
7477 * posix.c: #include <libc.h>, if it exists.
7479 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7480 don't even know if the latter exists.
7482 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7483 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7484 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7486 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7488 (scm_init_posix): Use them when initializing the Scheme constants
7491 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7493 * Makefile.in (libdir, includedir, bindir): Use the
7494 autoconf-supplied values, instead of deriving them ourselves.
7495 (pkgincludedir, datadir, pkgdatadir): New variables.
7496 (install, uninstall): Put the header files in a special
7497 subdirectory, not in the main search path.
7499 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7500 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7502 * Makefile.in (IMPLPATH): Deleted; never used.
7504 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7505 on the Tcl/Tk source any more.
7506 (INCLUDE_CFLAGS): Remove references to the above.
7508 * Makefile.in (version.o): Corrected dependencies.
7510 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7512 * libguile.h: #include "version.h"
7514 * init.c (scm_boot_guile): Call scm_init_version.
7515 * gscm.c (gscm_run_scm): Call scm_init_version.
7517 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7518 GUILE_VERSION): AC_DEFINE these.
7519 (acconfig.h): #undef the above symbols.
7521 * Makefile.in (libobjs): Add version.o.
7522 (installed_h_files): Add version.h.
7523 (c_files): Add version.c.
7524 (gen_c_files): Add version.x.
7525 (version.o): New rule.
7526 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7527 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7528 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

7534 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
7535 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7536 weaks.o): Add version.h to dependency lists.
7537 (markers.o): Remove duplicate rule.
7539 * version.h: New file.
7541 * version.c: New file.
7543 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7545 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7546 array; use it appropriately. Since GCC is quite happy to
7547 subscript functions, it never warned us about this; we should use
7548 -Wpointer-arith in the future. I guess we never tested
7551 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7553 * socket.c: Doc and copyright fixes.
7555 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7557 * debug.c: Fixed and improved gdb support.
7559 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7561 * socket.c: Added declaration of inet_aton to avoid compiler
7562 warning. (Hope this solution is correct.)
7564 * stime.c: Added declaration of ftime. (This is missing in
7567 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7569 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7571 * Makefile.in (c_files): add strerror.c.
7573 * strerror.c: new file from Emacs' sysdep.c.
7574 maybe configure should also check for sys_errlist.
7576 * configure.in (AC_REPLACE_FUNCS): add strerror.
7578 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7580 * debug.c (scm_init_debug): Added initialization for
7581 scm_evaluator_traps.
7583 * debug.h, debug.c: Various name changes.
7584 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7585 "debug-options-interface". See commentary in options.c.
7587 * options.h, options.c: Options now have documentation strings.
7588 Also added a long explanatory commentary.
7590 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7593 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7594 last_debug_info_frame is now updated in all cases.
7596 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7599 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7601 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7602 Added option STACK_CHECKING.
7604 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7606 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7608 * __scm.h: Removed symbols for debugging support.
7610 * acconfig.h: Added symbols for debugging support.
7612 * configure.in: Added user option for debugging support.
7613 --enable-debug will include the debugging code into libguile.a.
7615 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7616 scm_relocate_chunk_to_heap.
7618 * debug.c: New file: low-level debugging support. It also
7619 includes support for debugging with gdb. (The extensions to gdb
7620 are written by Per Bothner at Cygnus.)
7622 * debug.h: New file: low-level debugging support.
7624 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7625 argument pairs. Extensive modifications to the debugging
7626 evaluator. Added "SECTION:" commentaries to clarify what happens
7627 when, during double compilation. Renamed EVALIMP --> EVALIM.
7628 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7629 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7630 the beginning of the file. New procedure: scm_unmemocopy.
7631 Added some global state variables needed by the debugging
7632 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7633 check_entry, check_apply, check_exit, debug_options and
7634 evaluator_traps. New acro: undefine.
7636 * eval.h: Renamed EVAL --> XEVAL.
7638 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7639 --> scm_make_weak_key_hash_table.
7641 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7642 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7644 * libguile.h: Conditionally include debug.h
7646 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7647 scm_object_properties shouldn't return handle. `handle' now gets
7648 initialized in scm_set_object_properties_x. scm_object_properties
7649 doesn't any longer create an entry in scm_object_whash.
7651 * options.c: New file: handling of run time options.
7653 * options.h: New file: handling of run time options.
7655 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7657 * print.c: New procedure: scm_print_options
7659 * print.h: Defines for print options.
7661 * read.c: New procedure: scm_read_options
7663 * read.h: Defines for reader options.
7665 * root.h: Added scm_source_whash among scm_sys_protects.
7667 * srcprop.c: New file: source properties.
7669 * srcprop.h: New file: source properties.
7671 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7672 (Bug found by A. Green.)
7674 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7676 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7678 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7680 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7682 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7683 and should be called by the final client.
7685 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7687 * gc.h: Use the PROTO macro when declaring functions.
7688 * gc.c: Use the PROTO macro when declaring static functions.
7689 Remove the CPP hair around function definitions.
7691 * gc.c (scm_init_storage): Initialize scm_asyncs.
7693 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7694 preprocessor symbol; "__scm.h" is where it might get #defined.
7695 * __scm.h: Similar: #include <scmconfig.h> before testing
7698 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7700 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7702 * init.c (scm_boot_guile): Add init_func argument; call
7703 (*init_func) instead of calling scm_appinit; it's ucky to
7704 hard-code names for the user's procedures.
7705 * init.h (scm_boot_guile): Adjust declaration.
7707 * __scm.h (PROTO): New macro, for declaring functions with
7710 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7711 eliminate all the __STDC__ conditionals.
7712 (scm_boot_guile): Add declaration.
7713 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7714 Remove __STDC__ conditionals around function definitions; the
7715 declarations in init.h will provide the same information, more
7718 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7719 complain about it in the error message; the error message is
7720 adequate without that note, and there's nothing the user can do
7723 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7725 * Makefile.in (ancillary): Drop def.sed.
7727 * posix.c (scm_init_posix): Use numeric values, rather than
7728 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7729 F_OK. The symbols aren't available on some systems, and I'm
7730 pretty sure their values are fixed by common widespread practice.
7731 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7733 More functions unavailable on some systems.
7734 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7735 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7737 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7738 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7739 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7740 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7741 stub that signals an error as the #else.
7743 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7745 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
7747 * Fixes motivated by Petr Adamek <adamek@mit.edu>:

7918 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
7920 * gscm.h: gscm_mkarray eliminated (presumably was not being used

7927 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
7929 * ports.c: removed functions relating to the mapping between ports

7938 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
7939 handled correctly (SCM_FREEP was applied to them) -- test for

8314 * eval.c (SCM_CEVAL): if the function position evaluates
8315 to a macro, process it accordingly. (Previously, macros were
8316 handled only if the function position was a symbol naming a
