3 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
5 * lang.c: New file: Beginning of multi-language support.
7 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
9 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
10 (scm_dynamic_wind): Added argument checking for the after guard so
11 that we don't add garbage on the dynwind chain.
12 (scm_swap_bindings): Added.
14 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
15 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c

38 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
40 * ports.c, ports.h (scm_make_port_type): New interface for
41 creation of port types (replaces scm_newptob). Just as for the
42 smobs, we need to separate the internal representation of smob
43 types from the interface, so that we easily can add new fields and
44 rearrange things without caring about backward compatibility.
45 This change was forced by the need in GOOPS to create classes
46 representing port types.
47 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
48 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

57 (void_port_ptob, print_void_port, close_void_port, noop0):
58 Removed. Removed #include "genio.h" Added #include "objects.h",
61 * fports.c (prinfport): Moved code from ports.c.
63 (scm_fptob): Removed. Instead use new interface.
64 (scm_make_fptob): Added. (Need to create basic ports in a
65 specific order in ports.c.)

92 port (as in the filesys.c version).
94 * filesys.c (scm_truncate_file): removed.
96 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>

102 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
103 SCM_INOUT_PCLASS_INDEX): Added.
106 * Makefile.am: Removed genio.c, genio.x.
110 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
112 * init.c: Make sure that scm_post_boot_init_modules is called only
113 once. (Important when using a dumped image.; Thanks to Bernard
116 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
118 * guardians.c (scm_guardian_zombify): Separate scanning for
119 zombies from marking the pairs of the free list.
121 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
122 use the macros. (Thanks to Michael Livshin.)
124 * eval.c (scm_m_lambda): Let bodycheck check the body of the
125 lambda. Let your sins be purified by the blood of the lambda.
126 (Thanks to Eric Hanchrow.)

133 * filesys.c: #include <io.h>, if we have it.
134 * scmconfig.h.in: Regenerated.
136 * stime.c (ftime): Delete declaration for this function --- let
137 the system supply it.
139 Cleanups from John Bley.
141 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
143 * gsubr.c: Don't include "gsubr.h" twice.
145 Cleanups for compilation on Irix 6, from David Kaelbling.
147 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
148 regex_t pointer. This is what the callers have, mostly.
149 (scm_regexp_exec): Don't forget to pass the `rx' argument to
150 scm_regexp_error_msg.
152 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
153 int. That way, if we get a warning on this line, it's more likely
154 that we're really missing bits we care about.
156 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
159 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
160 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
161 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
162 cast at all is more appropriate in every case. At the moment, we
163 assume everywhere that SCM is an integral type anyway.

167 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
168 read_pos after scm_fill_buffer.
170 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
173 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
174 fports.c (fport_fill_buffer): implement the interface change.
176 * ports.c (scm_fill_buffer): interface change: no longer increments
177 read_pos past the character that's returned. it seems clearer to
178 leave it to the caller to decide what to do (thanks Jim).
180 * vports.c (sf_fill_buffer): put the read char into the buffer
181 as well as returning it.
183 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

197 * ports.c (scm_ftruncate): throw error if offset works out negative.
199 * strports.c (st_flush): increase string size in blocks of
200 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
201 it's greater and reset read_buf_size.
202 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
203 to be maintained for output ports too (it holds the written
204 part of the string, while write_buf may have unwritten buffer
206 (st_truncate): rewritten.
207 (top of file): added a few notes.
209 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
211 Patch from Greg Badros:
212 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
213 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
214 (function pointer) argument to scm_make_gsubr and scm_make_subr
215 calls. This avoids warnings in C++ programs using guile-snarf.
217 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
219 * strports.c (st_grow_port): set pt->read_pos. set
220 pt->read_buf_size one less than pt->write_buf_size if there's
221 an unwritten char at the end of the string. similarly for
223 (st_resize_port): renamed from st_grow_port.
224 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
225 seek from read_end instead of write_end for SEEK_END.

238 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
240 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

244 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
245 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
246 and "bigneg" smob types.
248 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
249 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

343 * struct.c, struct.h:
345 In order to support different kinds of deallocation, a destructor
346 slot has been added to struct vtables. This allows for structs
347 containing pointers to other memory blocks.

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

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

558 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
560 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
561 equivalent to fflush for the read buffer.
562 * ports.c (scm_newptob): set read_flush.
563 ports.c (void_port_ptob): set read_flush.
564 fports.c (local_read_flush): new proc. add to ptob.
565 strport.c (st_read_flush): likewise.
566 vport.c (sf_read_flush): likewise.
567 fports.h (struct scm_fport): remove random member. there's nothing
568 left but fdes. leaving it as a struct to allow for future changes.
569 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
570 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
571 ptob proc if the read buffer is filled.
573 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
575 * ports.h (scm_port): add a rw_random member and replace
576 reading and writing members with rw_active member.
577 SCM_PORT_READ/SCM_PORT_WRITE: new values.
579 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
581 * ports.h (struct scm_port_table): add writing and reading members
582 to replace write_needs_seek: it isn't good enough for non-fports.
583 ports.c, ioext.c, fports.c: corresponding changes.
584 (struct scm_port_table): give it a typedef and rename to scm_port.
585 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:

596 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
597 signals (it was only being done for handlers installed from Scheme).
598 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
599 waiting for input caused an EINTR error from read.
601 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
603 * ports.h (struct scm_port_table): make all the char members
604 unsigned, so they convert to int without becoming negative if large.
606 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
608 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
609 with threads enabled. rename this procedure to
610 fport_wait_for_input and take a port instead of a fdes.
611 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
613 * readline.c (scm_readline): Applied a patch from Greg Harvey to
614 get readline support working again: use fdopen to get FILE objects.
616 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
618 * gc.c (scm_init_storage): install an atexit proc to flush the
620 (cleanup): the new proc. it sets a global variable which can be
621 checked by the ptob flush procs to avoid trying to throw
622 exceptions during exit. not very pleasant but it seems more reliable.
623 * fports.c (local_fflush): check terminating variable and if set
624 don't throw exception.
625 * CHECKME: that the atexit proc is installed if unexec used.
627 * throw.c (scm_handle_by_message): don't flush all ports here.
628 it still causes bus errors.
630 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
633 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
635 * ports.c (scm_char_ready_p): check the port buffer and call the
636 ptob entry if needed.
638 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
639 ptob initialisers. use it in char-ready
641 * ioext.c (scm_do_read_line): moved from ports.c. make it static.

644 currently use shortbuf.)
646 * fports.c (scm_standard_stream_to_port): moved to init.c and
649 * init.c (scm_init_standard_ports): make stdout and stderr
650 unbuffered if connected to a terminal. with stdio they
651 were line-buffered by default.
653 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
656 * ports.h (scm_ptobfuns): change fflush return to void.
657 change flush proc definitions.
659 * strports.c (scm_call_with_output_string): get size from
660 buffer instead of port stream.
661 (st_flush): new proc.
663 * ports.h (struct scm_port_table): added write_end member,
664 as an optimisation. set it where write_buf_size is set.
666 * ports.h (struct scm_port_table): change stream from void *
667 back to SCM. SCM presumably must be large enough to hold a
668 pointer (and probably vice versa but who knows.)
669 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
671 (scm_puts): rewritten
672 * fports.c (local_ffwrite, local_fputs): removed.

685 * fports.c: set it to local_seek, new procedure.
688 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
689 use ptob for seek. take ptob instead of fport arg.
691 * ports.h (struct scm_port_table): new member write_needs_seek,
692 replaces reading member in fport struct.
694 * vports.c (sfgetc): store the getted char into the buffer.
695 rename to sf_fill_buffer and install it for fill-buffer in ptob.
696 the Scheme interface is still a procedure that gets a char.
697 (scm_make_soft_port): set up the port buffer (shortbuf).
699 * fports.c (local_fgetc, local_fgets): deleted.
700 * strports.c (stgetc): likewise.
701 * ports.c: scm_generic_fgets: likewise.

905 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
906 error messages, not the uninitialized string `str'. Love that
909 * strop.c (scm_substring_move_x): New function, which can handle
910 arbitrary overlapping substrings.
911 (substring-move-left!, substring-move-right!): These are
912 now just synonyms for substring-move!.

985 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
987 * numbers.c (isfinite): Define this macro if not defined: Return a
988 non-zero value if X is finite. (From ISO C 9x standard.)

1030 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1031 scm_misc_error when pos is a string. This allows for dispatching
1032 arbitrary error messages with one argument via SCM_ASSERT:

1041 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1043 Most of this batch of changes is about how to deal with extended
1044 types when an object system is loaded into Guile. A nice object
1045 system is capable of representing Guile's types as class objects.
1047 For example, we want a regular expression to be of class <regex>.
1048 But regular expressions are smobs which aren't under direct
1049 control of the object system, so there has to be some mechanism
1050 which informs the object system that a new class should be created
1051 which can represent the smob type. I call this a "wrapper class".
1053 * objects.c: #include "smob.h";
1054 (scm_class_keyword): Removed. (Class is automatically created by

1082 (scm_init_struct): Allocate scm_struct_table.
1083 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.

1098 hash table (in no particular order).
1100 Argh! For the umpteenth time I got compilation errors because of
1101 the "intuitive" name `kw'. This has to have an end:
1103 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1104 "kw" --> "keywords" everywhere.
1105 (I doubt that this will cause big compatibility problems since the

1259 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1261 * print.c (scm_iprin1): Use scm_procedure_name instead of
1262 scm_procedure_property for compiled closures.
1264 * tags.h (scm_tc7_pws): New procedure type. Four representations
1265 for procedure-with-setters were considered before selecting this
1268 1. A closure where the CODE and ENV slots are used to represent
1269 the getter and a new SETTER slot is used for the setter. The
1270 original getter is stored as a `getter' procedure property. For
1271 closure getters, the CODE and ENV slots contains a copy of the
1272 getter's CODE and ENV slots. For subr getters, the CODE contains
1275 2. A compiled closure with a call to the getter in the cclo
1276 procedure. The getter and setter are stored in slots 1 and 2.
1278 3. An entity (i.e. a struct with an associated procedure) with a
1279 call to the getter in the entity procedure and the setter stored
1280 in slot 0. The original getter is stored in slot 1.
1282 4. A new primitive procedure type supported in the evaluator. The
1283 getter and setter are stored in a GETTER and SETTER slot. A call
1284 to this procedure type results in a retrieval of the getter and a
1285 jump back to the correct eval dispatcher.
1287 Representation 4 was selected because of efficiency and
1290 Rep 1 has the advantage that there is zero penalty for closure
1291 getters, but primitive getters will get considerable overhead
1292 because the procedure-with-getter will be a closure which calls
1295 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1296 <procedure-with-setter>, but together with rep 2 it suffers from a
1297 three level dispatch for non-GOOPS getters:
1299 cclo/struct --> dispatch proc --> getter
1301 This is because the dispatch procedure must take an extra initial
1302 argument (cclo for rep 2, struct for rep 3).
1304 Rep 4 has the single disadvantage that it uses up one tc7 type
1305 code, but the plan for uniform vectors will very likely free tc7
1306 codes, so this is probably no big problem. Also note that the
1307 GETTER and SETTER slots can live directly on the heap, using the
1308 new four-word cells.

1559 as doing it in bignums, but at least it's good enough for
1560 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1562 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1563 subexpressions. (Thanks to Charbel Jacquin.)
1565 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1567 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1568 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1569 (scm_make_named_hook): New function.
1571 * feature.c: Added #include "eval.h".
1573 * modules.c (scm_make_module): Beautify the module.
1575 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1577 * modules.c, modules.h: New files: C interface to modules. (This
1578 is necessary in order to interface the object system to Guile
1579 properly. The guts of these modules will be replaced by the new
1580 module system in the future.)
1582 * init.c: Added #include "modules.h"
1583 (scm_boot_guile_1): Call scm_init_modules.
1584 (invoke_main_func): Call scm_post_boot_init_modules.
1586 * Makefile.am: Added modules.c, modules.x, modules.h.
1588 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1590 * procs.c: #include "objects.h"
1591 (scm_procedure_p): Return #t also on structs which are operators.
1593 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1594 <operator-metaclass> and <entity-class> to <standard-class>,
1595 <operator-class> and <entity> in order to conform with STKlos
1598 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1599 which isn't an operator.
1600 (SCM_APPLY): Ditto, but jump to badproc.
1602 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1604 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1605 Previously, structs implanted in code were interpreted as forms
1606 the operator of which was a gloc. We solve this by checking for
1607 the zero in the emulated vcell in the struct vtable. Since
1608 implanted structs always will look like forms with a gloc
1609 operator, execution will only be slowed down by maximally one
1610 extra test-and-branch per application.
1612 * evalext.c (scm_definedp): Removed check for isyms; Added a
1613 second optional argument: It is now possible to supply an
1614 evaluation environment in which to look for the symbol.
1616 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1618 * readline.c (scm_init_readline): Set
1619 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1621 * coop.c (coop_condition_variable_wait): Removed
1622 (coop_condition_variable_wait_mutex): Folded logic of
1623 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1624 prevent condvar signal lossage. Previously, another thread could
1625 start to run after unlocking the mutex but before putting the
1626 current thread on the wait queue. If that thread then would
1627 signal the first, the signal would be lost. (Thanks to Christian
1630 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1632 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1635 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1637 * objects.c (scm_i_make_class_object): Renamed from
1638 make_class_object; exported; error checking moved to
1639 scm_make_class_object and scm_make_subclass_object.
1640 (scm_make_class_object, scm_make_subclass_object): Use
1641 scm_i_make_class_object.
1642 (scm_make_subclass_object): Let the subclass have same metaclass
1645 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1647 * debug.c (scm_debug_options): Bugfix: Set the value of
1648 scm_stack_checking_enabled_p after setting debug options;
1649 #include "stackchk.h". (Thanks to Richard Polton.)
1651 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1653 * unif.c (scm_array_contents): removed unnecessary test for 0
1656 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1658 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1659 Replaced by macro `collect' in boot-9.scm.
1661 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1663 * eval.c (scm_copy_tree): Copy source properties if existent.
1665 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1666 don't, we may end up passing memoized source to a transformer.)
1668 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1670 * stack.c (get_applybody): Help function which lookups the first
1671 body form of the apply closure.
1672 (read_frames): Prevent the source of the first form of the apply
1673 closure from being recorded. This would only be confusing.
1675 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1676 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1678 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1680 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1682 (read_frames): Use SCM_MACROEXPP.
1684 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1686 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1687 don't contain interesting information since all arguments are
1688 present in the frame which applies the compiled closure anyway.);
1689 Skip the transformer application frames.
1691 * print.c (scm_iprin1): Print gsubrs as primitives.
1693 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1695 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1697 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1698 that we can identify these in a backtrace. (This change doesn't
1699 introduce any significant speed penalty.)
1701 * eval.c: Added note about `serial-map' using scm_map.
1703 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1704 readline options. They should reside in their own options array.
1706 * readline.c, readline.h (scm_readline_options,
1707 scm_readline_opts): Moved readline options here.
1709 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1711 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1712 SCM_ROCHARS instead of SCM_CHARS.
1714 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1715 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1717 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1719 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1720 This is quite important since the latter clears the
1721 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1722 every single character read...
1724 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1726 * print.c (scm_iprin1): Removed suspect looking (and indeed
1727 malevolent) semicolon after test for user supplied closure print
1728 procedure. (Thanks to Telford Tendys.)
1730 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1731 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1732 starting to search the list. Removed call to sloppy_mem_check.
1734 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1735 procedures: Same as scm_delq_x et al, but delete maximally one
1738 * options.c (scm_options, scm_init_options): GC-protect option
1739 values of type SCM. (Thanks to Telford Tendys.)
1741 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1743 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1744 make sure that there always is a "real" scm_lookupcar.
1746 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1748 * read.c, read.h (scm_read_opts): New read options
1749 "history-length" and "history-file".
1750 (scm_read_options): Stifle history to history length.
1752 * readline.c (scm_read_history, scm_write_history): New procedures.
1754 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1756 * eval.h (scm_macro_eval_x): Removed declaration.
1758 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1759 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1760 Renamed and made global.
1762 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1763 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
1765 * evalext.c, evalext.h: New files. Contain non-R5RS things
1766 having to do with evaluation.
1768 * evalext.c (scm_serial_map): New procedure: Version of `map'
1769 which guarantees that the procedure is applied to the lists in
1771 (scm_m_sequence_to_list): New syntax: Version of `begin' which
1772 returns a list of the results of the body forms instead of the
1773 result of the last body form.
1774 (scm_definedp, scm_m_undefine): Moved from eval.c
1776 * evalext.h (scm_m_sequence_to_list): Added declaration.
1778 * macros.c, macros.h: New files.
1779 (scm_procedure_to_syntax, scm_procedure_to_macro,
1780 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
1781 scm_macro_name, scm_macro_transformer): Moved from eval.c
1782 (scm_make_synt): Moved from eval.c
1784 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
1786 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
1789 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
1791 * debug.c, print.c: Added #include "macros.h".
1793 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1795 This change adds the ability to use `unread-char' multiple times
1796 without interspersed reads and adds the new procedure
1797 `unread-string'. The change is optimized for the common case of
1798 unreading a single character. This is also the reason behind the
1799 choice to store characters in the port itself: in most cases no
1800 extra malloc is required.
1802 The amount of code in some macros in ports.h has been increased to
1803 the extent that they would fit better as C functions, but, since
1804 this code belongs to the port representation, such functions
1805 should be placed in ports.c which would cause calls back and forth
1806 between ports.c and genio.c. That is not good for performance.
1807 Also, keeping them as macros allows the compiler to do some
1808 optimizations which are needed to make the current interface
1809 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
1811 One benchmark (Guile startup time) indicates an increase of
1812 loading speed of 1%. Another (reading (using `read') boot-9.scm
1813 10 times) shows no change in performance.
1815 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
1816 made to find a beautiful solution.)
1818 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
1819 (SCM_TRY_CLRDY): New macro: Only clear the first unread
1820 character. (SCM_CLRDY clears all.)
1821 (SCM_N_READY_CHARS): New macro: Returns number of unread
1822 characters in a port. Returns wrong answer if SCM_CRDYP is false.
1823 (struct scm_port_table): New fields: `entry' contains port table
1824 index, `cp' points to last unread char, `cbuf' is the buffer for
1825 unread chars, `cbufend' points after end of the character buffer.
1827 * ports.h, ports.c (scm_unread_string): New procedure.
1828 (scm_grow_port_cbuf): New function.
1830 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
1832 (scm_generic_fgets), fports.c (local_fgets): Use a loop
1833 to read unread characters. Use SCM_TRY_CLRDY instead of
1836 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
1838 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
1840 * genio.c, genio.h (scm_ungets): New function.
1842 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
1845 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1847 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
1848 declarations. (Thanks to Russ McManus.)
1850 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1852 * numbers.c (num2long): As a software archeologist, I'm proud of
1853 this finding! :) Preliminary dating suggests an almost 4 year old
1854 remnant from the SCM ancestor. The sample has been removed from
1855 the finding site and is now safely stored in the repository.
1857 * numbers.h: Removed prototype for num2long.
1859 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
1861 * gh_data.c (gh_scm2doubles): Make it possible to pass result
1862 array as second arg.
1863 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
1864 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
1865 * gh.h: Updated and added prototypes.
1867 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1869 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
1871 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
1873 * guile-snarf.in: Never generate an empty file. (Thanks to
1876 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
1877 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
1878 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
1879 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
1880 gh_new_procedure5_0): Specify argument types, to appease C++
1881 compilers. (Thanks to Brad Bowman.)
1883 Bug reports from Russ McManus:
1884 * guile-snarf.in: If the CPP environment variable is set, use that
1885 as the C preprocessor, instead of the preprocessor autoconf
1887 * snarf.h (SCM_PROC): Cast the function pointer passed to
1888 scm_make_gsubr, to satisfy C++.
1890 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
1891 Use the handler passed, instead of ignoring it and using
1892 gh_standard_handler. (Thanks to Etienne Bernard.)
1894 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
1896 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
1899 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
1901 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

1916 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
1919 * script.c (scm_compile_shell_switches): Define
1920 use-emacs-interface in the root module, so the repl code can see
1921 it. See today's change to top-repl in ice-9/boot-9.scm.
1923 * filesys.c (set_element, get_element): Make sure that `element'
1924 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
1925 Boekemeier and Jorgen "forcer" Schaefer.)
1927 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
1929 * chars.c (scm_charnames): In ASCII character name table, make
1930 newlines print as #\newline by default, not #\nl.
1932 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
1933 alphabetical order. Oh thrills. But it helps me know how far
1934 along in the compilation I am.
1935 * Makefile.in: Regenerated.
1937 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1939 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
1940 #bytes(...) to #y(...), and syntax for short vectors from
1941 #short(...) to #h(...). This may seem nutty, but, like the other
1942 uniform vectors, byte vectors and short vectors want to have the
1943 same print and read syntax (and, more basic, want to have read
1944 syntax!). Changing the read syntax to use multiple characters
1945 after the hash sign breaks with the conventions used in R5RS and
1946 the conventions used for the other uniform vectors. It also
1947 introduces complexity in the current reader, both on the C and
1948 Scheme levels. (The Right solution is probably to change the
1949 syntax and prototypes for uniform vectors entirely.)
1951 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
1953 Don't use local_fgets on sockets; ftell doesn't work on sockets.
1954 (Thanks to Jorgen "forcer" Schaefer.)
1955 * ports.h (SCM_NOFTELL): New flag.
1956 * fports.c (local_fgets): If it's set, use the generic fgets.
1957 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
1959 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1961 * script.c (scm_compile_shell_switches): Add handling of -q switch
1962 (inhibit loading of user init file).
1963 (scm_shell_usage): Add usage text for -q switch.
1964 (scm_compile_shell_switches): Always load user init file first if
1965 it is loaded at all.
1967 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
1969 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
1970 and is now broken under NetBSD. I can't fathom what it's trying
1971 to do, so I've replaced it with something that I do understand,
1972 which seems to work, and which isn't broken on NetBSD. "Progress?
1973 You Decide." (Thanks to Perry Metzger.)
1975 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
1976 signed/unsigned comparison.
1978 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
1980 Warning fixes from Greg Harvey:
1981 * unif.c (scm_array_set_x): initializer for pos
1982 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
1983 * struct.c (scm_struct_ref, scm_struct_set_x): Added
1984 initializers for field_type, since EGCS so desparately wants to
1986 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
1987 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
1988 when GUILE_DEBUG is defined.
1989 * dynwind.h (scm_wind_chain): Same.
1990 * ports.h (scm_pt_size, scm_pt_member): Same.
1991 * print.h (scm_current_pstate): Same.
1992 * procs.h (scm_make_cclo): Same.
1994 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
1996 Handle short and long long uniform arrays properly. (Thanks to
1998 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
1999 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2000 scm_tc7_llvect (long long vectors).
2002 Change the way libguile and boot-9.scm are timestamped, to try to
2003 get rid of these spurious mismatch warnings. Now both
2004 libguile/versiondat.h and ice-9/version.scm are generated directly
2005 by the configuration process, rather than having version.scm
2006 generated directly, and libguile/versiondat.h generated by the
2007 Makefile, which is generated by configure. It seems that
2008 sometimes the Makefile would change, but versiondat.h depends on
2009 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2010 * Makefile.am (versiondat.h): Target removed; this is generated
2011 directly by the configure script now.
2012 (BUILT_SOURCES): Remove versiondat.h.
2013 * versiondat.h.in: New file, transformed by the configure script
2015 * Makefile.in: Regenerated.
2017 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2018 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2019 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2020 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2021 if we want to use them in a header file some day, we can. (Thanks
2022 to Michael Livshin.)
2024 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2025 SCM numbers, so we won't have rollover problems; the range of a
2026 signed long in milliseconds is about 25 days. (Thanks to Karl
2029 Don't redefine sleep and usleep; fix this problem now.
2030 * coop.c (sleep, usleep): Remove declarations; we don't use or
2031 redefine these any more.
2032 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2033 job of usleep and sleep in a thread-friendly way. We can use
2034 these in the rest of Guile. Define versions for systems both with
2035 and without iselect.
2036 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2037 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2038 we're just using it, not redefining it, we can use a K&R style
2040 (sleep): Declare this, too, if the system hasn't.
2041 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2042 scm_uthread_sleep if they're available; otherwise, just call the
2044 * scmconfig.h.in: Regenerated.
2046 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2048 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2050 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2052 * threads.c: Doc fix.
2054 The argument type of usleep varies from system to system,
2055 as does the return type. We really shouldn't be redefining usleep
2056 at all, but I don't have time to clean that up before the 1.3.
2057 release. It's on the schedule for afterwards. (Thanks to Julian
2059 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2061 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2062 * scmconfig.h: Regenerated.
2064 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2065 right way to handle system variation. Autoconf's approach is the
2067 * simpos.h (scm_software_type): Declaration deleted.
2069 * script.c (scm_find_executable): Don't test if unix is #defined
2070 here; first, NetBSD doesn't #define it, and second, it's the wrong
2071 way to go about these things. (Thanks to Perry Metzger.)
2072 (dld_find_executable): Delete this MSDOS support code. This isn't
2073 the way we want to support this; it needs to be rethunk at a
2076 * genio.c (scm_do_read_line): Don't just politely check that the
2077 line was either non-empty or EOF. Abort if it's empty and not
2080 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2082 * scmconfig.h.in: Regenerated.
2084 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2087 * genio.c (scm_do_read_line): Count lines correctly when the file
2088 doesn't end in a newline.
2090 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2092 * genio.c (scm_do_read_line): Maintain the line count correctly.
2093 (Thanks to Harvey J. Stein and Greg Harvey.)
2095 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2098 * numbers.c (big2str): Protect t from garbage collection until
2099 we're done. (Thanks to Gary Houston.)
2101 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2103 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2105 * Makefile.in: Regenerated.
2107 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2108 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2111 Do magic to mix reads and writes on stdio FILE-based ports.
2112 (Thanks to Christian Lynbech.)
2113 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2115 (pre_read, pre_write): New functions.
2116 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2117 local_fputs): Call them.
2118 (local_fflush): Mark the port as ready for reading and writing.
2119 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2120 flags on new port objects. This might not be accurate --- who
2121 knows what state the FILE * is in when we get it --- but it won't
2122 do extraneous calls to fflush or fseek, so it's no worse than the
2123 behavior before this change.
2124 * ports.h: Add comment.
2126 Centralize the creation of port objects based on stdio FILE * in
2127 fports.c; don't just throw them together anywhere.
2128 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2129 what the rest of Guile wants. Don't set the revealed count;
2130 that's only appropriate for stdin, stdout, stderr.
2131 (scm_standard_stream_to_port): This function does set the revealed
2133 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2134 not scm_stdio_to_port.
2135 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2136 * fports.c (scm_open_file): Same.
2137 * posix.c (scm_pipe): Same.
2138 * socket.c (scm_sock_fd_to_port): Same.
2139 * ioext.c (scm_fdopen): Same.
2140 (scm_freopen): Moved from here to...
2141 * fports.c (scm_freopen): ... here. This is really something that
2142 munges the internals of an fport, so it should go here.
2143 * fports.h (scm_stdio_to_port): Adjust prototype.
2144 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2145 * ioext.h (scm_freopen): Prototype removed.
2147 * filesys.c (set_element, get_element): This can work on both pipe
2148 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2151 * scmconfig.h.in: Regenerated.
2153 Change the definition of the functions in scm_ptobfuns so that
2154 they get passed the port object, not the port's stream.
2155 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2156 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2157 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2158 Pass the port itself to the scm_ptobs function.
2159 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2160 scm_generic_fgets): Same.
2161 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2162 getc_void_port, fgets_void_port, close_void_port): Just change the
2163 argument names; these functions don't really do anything.
2164 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2165 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2166 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2167 Also, use prototyped definitions, and get rid of the extra
2169 (scm_fptob, scm_pipob): We don't need casts here any more.
2170 * strports.c (prinstpt): Use prototype declarations.
2171 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2172 and use SCM_STREAM to get the string info. Also, use prototyped
2173 definitions, and get rid of the extra declarations.
2174 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2177 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2178 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2180 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2181 scm_fgets, for consistency.
2182 (scm_fptop, scm_pipob): References updated.
2184 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2186 Include the source location in error messages for scripts.
2187 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2188 stack is still there when we catch the error.
2189 * throw.c (handler_message): If we are handling an error with a
2190 message, then put together the proper arguments and call
2191 scm_display_error, instead of scm_display_error_message. That
2192 displays source location, if it can find it.
2194 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2196 * gc.c (scm_unprotect_object): Change this so that calls to
2197 scm_protect_object and scm_unprotect_object nest properly.
2198 (scm_protect_object): Doc fixes.
2200 * strings.c (scm_string_set_x): Require the argument to be a
2201 writable string, not a substring or a symbol.
2202 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2203 (Thanks to John Redford and Charbel Jacquin.)
2205 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2207 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2209 * eval.c (safe_setjmp): Remove this misunderstanding.
2210 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2213 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2215 * libguile.h: Mark these as C declarations, for compilation by C++
2218 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2219 __cplusplus clause. I seriously doubt this ever worked the way
2220 the author seems to have intended.
2222 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2224 Utterly needless cleanups to hopelessly messy code.
2225 * ports.c: Doc fixes.
2226 (scm_fflush): Moved to ...
2227 * genio.c (scm_fflush): ... here, amongst all the other port
2228 method invocation functions.
2229 * genio.h, ports.h: The prototype moves too.
2231 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2233 * backtrace.c (display_error_body): The current frame does not
2234 always have a parent frame; consider a function called directly
2235 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2238 * alloca.c (alloca): Undo yesterday's changes, and simply call
2239 malloc directly for storage, and abort if we don't get what we
2240 want. The situation is much simpler --- just call malloc. Emacs
2241 has bizarre/evil requirements (signal handlers might malloc unless
2242 you set this global flag, so you have to set the flag around all
2243 calls to malloc) which we are certainly not going to conform to,
2244 so we can do the simple and obvious thing.
2246 * coop.c (coop_condition_variable_wait): Make this function
2247 static. It's only useful internally --- you should never just
2248 wait on a condition variable.
2249 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2251 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2253 * unif.c (scm_array_set_x): Accept any kind of number as an
2254 element for a uniform vector of doubles. This is more consistent
2255 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2257 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2258 works; I can't conveniently test it myself. (Thanks to Dvid
2259 Tillman for the bug report.)
2261 * init.c: Doc fixes.
2263 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2264 from here, not from scm_compile_shell_switches (which is a pretty
2265 dumb place to do it).
2266 (scm_load_startup_files): New function.
2267 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2268 * script.c (scm_compile_shell_switches): Don't load the startup
2270 (scm_ice_9_already_loaded): Variable moved.
2271 * init.c (scm_load_startup_files): Prototype for new function.
2272 * gh_init.c (gh_enter): Doc fix.
2274 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2276 Some anti-warning changes from Greg Harvey.
2277 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2278 warnings when it doesn't understand our NORETURN declarations in
2280 * posix.c (scm_mknod): Similar.
2282 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2284 * posix.c (scm_getpwuid): If we can't find an entry, return our
2285 own message, instead of using scm_syserror --- the getpwMUMBLE
2286 functions don't set `errno' to anything interesting.
2288 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2290 Get rid of warnings from the cooperative threading system.
2291 * threads.h (scm_single_thread_p, scm_yield,
2292 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2293 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2294 scm_wait_condition_variable, scm_signal_condition_variable): Add
2295 prototypes for these Scheme-visible functions.
2296 * coop-defs.h (coop_next_runnable_thread,
2297 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2298 Prototypes for these here, even though they're from iselect.c.
2299 (coop_condition_variable_wait, coop_join): Add prototypes.
2300 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2301 scm_threads_free_condvar): Make these smob functions static.
2302 * coop-threads.h (coop_init): Give this a real prototype.
2303 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2304 (coop_next_runnable_thread): No need to provide prototype; it's in
2307 * scmconfig.h.in: .detarenegeR
2309 * iselect.c, threads.c: Doc fixes.
2311 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2313 * Makefile.in: Regenerated with a patched automake, to get
2314 dependency generation right when using EGCS.
2316 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2317 warning. (Thanks to Robert Pluim.)
2319 * inet_aton.c (inet_aton): Reassure the compiler that the
2320 arguments to the <ctype.h> macros are all unsigned characters, not
2323 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2325 Getting rid of more warnings...
2326 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2327 today's change to ../configure.in.
2328 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2329 * scmconfig.h.in: Regenertaded.de.,.__
2330 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2331 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2334 * readline.c: Doc fix.
2335 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2336 * readline.h (scm_filename_completion_function): Add prototype.
2337 (scm_init_readline): Make this into a prototype.
2339 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2340 declare this, instead of calling scm_make_subr manually.
2342 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2344 * readline.h (scm_init_readline): Add prototype for this.
2345 (scm_init_readline): Make this a real prototype.
2347 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2349 Warning fixes from Maciej Stachowiak:
2350 * backtrace.h (scm_display_application, scm_backtrace): Add
2352 * debug.c (scm_m_start_stack): Make this function static.
2353 * fluids.h (scm_fluid_p): Add prototype.
2354 * procprop.c (scm_i_procedure_arity): Make this function static.
2355 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2356 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2357 * root.h (scm_dynamic_root): Add external prototype.
2358 * scmsigs.h (scm_usleep): Add external prototype.
2359 * script.h (scm_init_script): Use prototype, not K&R decl.
2360 * stacks.h (scm_stack_id): Add external prototype.
2361 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2363 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2365 * gh.h: took out the definitions of vset and vref, since they are
2366 replaced by the proper vector routines that correspond to the R4RS
2369 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2371 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2372 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2373 third argument, a C expression that should result in a SCM value,
2374 which is used to initialize the variable. Reimplemented
2375 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2378 * version.h (scm_libguile_config_stamp): Add prototype.
2379 (From Maciej Stachowiak.)
2381 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2383 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2384 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2386 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2388 * print.c (scm_iprin1): Rather than having one i, and using it in
2389 several places, declare a fresh i local to each block where it is
2390 used, and give it a signedness appropriate to its use in each case.
2391 (scm_iprlist): Same.
2393 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2394 comparison warnings.
2396 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2397 signed/unsigned clashes.
2399 * posix.h (scm_tmpnam): Added prototype.
2401 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2402 scm_make_subclass_object): Add external prototypes.
2404 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2405 comparison is okay here.
2407 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2409 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2410 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2412 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2415 * load.c (swap_port): Make this function static.
2417 * load.c (scm_search_path): Make max_path_len and max_ext_len
2418 unsigned, since they're compared against string sizes.
2420 * load.c (init_build_info): Make i unsigned.
2422 * ioext.h (scm_read_line): Add prototype.
2424 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2425 scm_hash_fn_remove_x): Make hash bucket index local variable k
2426 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2427 accurately as possible.
2429 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2430 comparisons, and range checking to make sure those casts are
2433 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2434 signed/unsigned comparisons.
2436 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2437 avoid signed/unsigned comparisons.
2438 * smob.h (scm_numsmob): Change extern declaration to match.
2440 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2441 avoid signed/unsigned comparisons.
2442 * ports.h (scm_numptob): Change extern declaration to match.
2443 (scm_current_load_port, scm_set_port_line_x,
2444 scm_set_port_column_x): New prototypes.
2446 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2447 test code, and it causes warnings.
2449 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2450 gh_uniform_vector_ref): Added prototypes.
2452 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2453 debugging support unconditionally. That's backtrace.c, stack.c,
2454 debug.c, and srcprop.c.
2455 (EXTRA_libguile_la_SOURCES): Omit those from here.
2456 * Makefile.in: Regenerated.
2458 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2460 * options.c (scm_options): Bugfix: Allow empty list of options!
2462 * debug.c, debug.h (scm_single_step): Removed.
2463 (scm_with_traps): New procedure. This procedure could easily be
2464 written in Scheme but needs to be highly optimized.
2466 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2468 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2469 Check SCM_TRAPS_P before trapping.
2471 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2473 Changes to avoid signed/unsigned comparison warnings.
2474 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2475 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2476 so they can have appropriate types for each application. Make i
2477 signed. Use initializers in some spots. I'll probably pay for
2479 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2480 (scm_must_realloc): Make nm unsigned.
2481 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2482 (scm_init_storage): Use prototype-style definition, and make the
2484 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2485 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2487 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2488 avoid signed/unsigned comparison warnings, and because the return
2489 value of readlink may be -1. Don't bother casting the third
2490 argument to readlink.
2492 * filesys.c (scm_dirname, scm_basename): Move these to their own
2493 page, at the end of the file.
2494 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2496 * eval.h (scm_eval_options_interface): Add external prototype for this.
2497 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2499 * eval.c (scm_lookupcar1): Make this static.
2501 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2502 Make these prototype declarations, not K&R-style.
2504 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2505 unsigned comparison warning.
2507 * appinit.c: File removed. It had a single function in it, empty,
2508 whose reason for existence is explained in no documentation or
2509 comment. I think it's there as a default for some Tcl-style
2510 initialization, but Tcl abandoned that approach a while ago.
2511 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2512 (BUILT_SOURCES): Remove appinit.x.
2513 * Makefile.in: Regenerated.
2515 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2517 * Makefile.in: Regenerated using the last public version of
2518 automake, not the hacked Cygnus version.
2520 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2522 Remove Totoro kludge.
2523 * Makefile.in, scmconfig.h.in: Regenerated.
2524 * init.c, readline.c: Don't check if TOTORO is #defined.
2526 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2528 * Makefile.am: Adjust for new thread configuration system.
2529 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2530 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2532 (THREAD_LIBS): Definition deleted; automake will generate such
2533 things automatically.
2534 * Makefile.in: Regenerated.
2536 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2538 Simplify smob and port marking; set the mark bit in the generic
2539 marking code, and make marker routines only responsible for
2540 turning up outgoing pointers.
2541 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2542 before calling the marking function. Don't call the marking
2543 function if it's zero.
2544 * markers.c (scm_mark0): Just return #f. This function isn't
2545 necessary at all now, but it's harmless to call it. We'll leave
2546 it in so other folks' code doesn't croak at link time.
2547 (scm_markcdr): Don't call SCM_SETGC8MARK.
2548 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2549 * dynl.c (mark_dynl_obj): Same.
2550 * root.c (mark_root): Same.
2551 * srcprop.c (marksrcprops): Same.
2552 * unif.c (markra): Same.
2553 * variable.c (scm_markvar): Same.
2554 * ports.c (scm_markstream): Same.
2555 (void_port_ptob): Specify zero for our marking function.
2556 * debug.c (debugobjsmob): Same.
2557 * dynwind.c (guardsmob): Same.
2558 * filesys.c (dir_smob): Same.
2559 * fluids.c (fluid_smob): Same.
2560 * fports.c (scm_fptob, scm_pipob): Same.
2561 * mallocs.c (mallocsmob): Same.
2562 * regex-posix.c (regex_t_smob): Same.
2563 * smob.c (freecell, flob, bigob): Same.
2564 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2565 * throw.c (jbsmob, lazy_catch_funs): Same.
2567 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2569 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2570 scm_copy_tree on code in order not to let memoized code to leak
2571 out. Thus, scm_copy_tree needs to copy vectors as well since
2572 quasiquote can introduce evaluated code also inside vector
2575 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2577 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2579 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2580 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2583 * unif.c: Say that ivect and uvect are of type signed and unsigned
2584 long instead of int in commentary so that it correctly describes
2587 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2589 * stime.c: Removed declaration of strptime. (It should be
2590 declared by the system headers. If it turns out that some systems
2591 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2593 * stime.h: Renamed TIMEH --> STIMEH
2595 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2596 to increase portability, don't use structure assignment.
2597 (Thanks to Nicolas Neuss.)
2599 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2601 (finalize_fd_sets): Added empty statement after last case label.
2602 (Thanks to Nicolas Neuss.)
2604 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2607 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2609 * init.c, readline.c: OK, I won't have these readline.x bug
2610 reports anymore. We've had them since April. The current reason
2611 is a completely unintelligible failure of totoro.red-bean.com to
2612 do the test for rl_getc_function in libreadline correctly. This
2613 kludge overrides the test if we're on totoro so that the snapshot
2614 generation process can work.
2616 * readline.c: Define a strdup replacement if not existent on system.
2618 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2620 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2621 This change makes scm_make_vector R5RS compatible. We cannot keep
2622 the third argument since people want to be able to deduce the form
2623 of the C function call only by looking at R5RS. (At the same time
2624 we have removed some unnecessary complexity!)
2626 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2627 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2628 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2629 argument in call to scm_make_vector.
2631 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2633 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2634 This macro is useful in applications.
2636 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2638 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2639 (scm_parse_path, scm_search_path): New Scheme level procedures.
2641 * load.h (scm_internal_parse_path, scm_parse_path,
2642 scm_search_path): Declared.
2644 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2646 * filesys.c (dirname, basename): New procedures.
2648 * init.c (scm_boot_guile_1): Removed condition around
2651 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2652 new data type (guards) for representation of C level guards and
2653 data on the wind chain.
2654 (scm_internal_dynamic_wind): New function.
2656 * dynwind.h: Declare scm_internal_dynamic_wind.
2658 * root.h (scm_root_state): Added scm_cur_loadp.
2660 * root.c (mark_root): Added comment about cur_loadp.
2662 * load.c: #include "dynwind.h";
2663 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2666 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2668 * ports.c (current-load-port): New procedure.
2670 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2672 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2673 not a tty, return #f.
2675 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2676 to Julian Satchell and Roland Kaufmann.)
2678 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2679 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2681 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2683 * debug.h, debug.c (scm_start_stack): New function. Implements
2684 the guts of old scm_m_start_stack.
2686 * debug.c (scm_m_start_stack): Use scm_start_stack.
2688 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2689 start_stack and restart_stack. (These have static scope.)
2691 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2693 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2694 readline functions to come in release 2.3. (Thanks to Chet
2696 (handle_errors): Use the above functions.
2698 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2700 * readline.c: Improvements for readline support: Handle errors
2701 better; Implement before-read-hook.
2703 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2705 * init.c (scm_boot_guile_1), readline.c: Test for
2706 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2707 assure that we have version >= 2.1.)
2709 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2711 * readline.c (scm_readline): Defer interrupts while we're calling
2714 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2715 away the string to add_history.
2716 (completion_function): Do completion for readline. (Thanks to
2718 (scm_filename_completion_function): New procedure: Filename
2720 (current_input_getc): New function. Use this one instead of
2721 standard getc from readline.
2723 * throw.c, throw.h (scm_handle_by_throw): New function: This
2724 handler throws errors to next handler on the dynwind chain.
2726 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2728 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2731 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2733 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2735 (scm_procedure_properties): Modified to return arity together with
2737 (scm_procedure_property): Added the read-only property `arity'.
2738 (scm_set_procedure_property_x): It is an error to set the `arity'
2741 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2742 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2744 * procprop.h (scm_sym_arity): New symbol.
2746 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2747 to set the dispatch procedure of an operator or entity object.
2749 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2750 Made procedure slots read-only.
2752 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2753 scm_tcs_cons_gloc case in zero args switch; Fixed args
2754 construction for operators in scm_tcs_cons_gloc case in two args
2757 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2759 * fluids.c: Removed use of assert.h (in order to avoid
2762 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
2764 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
2766 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
2767 change makes the evaluator safer at the cost of evaluation speed.
2768 It handles the case when the user has added a non-immediate
2769 improper end of the application form, e.g., `(+ 0 . x)'.
2770 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
2771 minimize the extra cost as much as possible. The new code is
2772 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
2773 problem with structs planted directly in the code (e.g. by a
2774 macro). This no longer causes segmentation fault. (Thanks to
2777 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
2778 arg `proc' in order to be able to throw errors; New argument
2781 * Removed extra #include "debug.h"
2783 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
2785 * scmsigs.c: Declare usleep as returning void on some systems.
2786 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
2789 * coop.c (usleep): Return void on some systems.
2791 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2793 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
2795 * coop.c: Changed return type of usleep to int.
2797 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
2798 isn't found in the OS.
2800 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
2801 isn't enabled. (Thought that I had made this change ages ago...)
2803 * iselect.c: Declare bzero if not defined by OS.
2805 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2807 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
2808 condition. (Thanks to John Tobey.)
2810 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
2811 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
2814 * __scm.h: Start the long-term project of moving to POSIX threads.
2815 Phase 1: Classification of all critical sections.
2816 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
2817 for A sections. (See comments in __scm.h for details.)
2819 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
2820 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
2822 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2824 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
2825 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
2826 (libpath.h, versiondat.h): Replaced dependency on Makefile with
2827 dependencies on $(srcdir)/Makefile.in
2828 $(top_builddir)/config.status in order to avoid circularity.
2830 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
2831 from argc if argc was 0 initially.
2833 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
2834 in generation of libpath.h.
2836 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
2838 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
2839 libguile from 2 to 3.
2841 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
2843 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
2845 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
2847 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
2848 scm_set_port_column_x, scm_port_filename,
2849 scm_set_port_filename_x): Removed optional arguments. Added
2850 proper argument checking.
2852 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
2853 stack size in machine words.
2855 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
2856 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
2857 to Ole Myren Röhne.)
2859 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
2861 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
2862 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
2864 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
2867 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
2868 procedure apply: Copy argument lists before pushing them unto the
2869 environment so that the environment won't get mutated due to
2870 manipulation of procedure arguments. This should perhaps be
2871 regarded as a temporary solution until someone finds a more
2872 efficient one. (Thanks to Maciej Stachowiak.)
2874 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
2876 * script.c (scm_compile_shell_switches): Use "guile" as default
2877 zero arg if argc is NULL.
2879 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
2881 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
2882 is zero. (Thanks to Dirk Herrmann.)
2884 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
2886 * ports.c (scm_add_to_port_table): First line is now line 0
2887 (was 1). (Interface changed according to suggestion by Per
2890 * backtrace.c (display_header): Add 1 to line and column numbers
2891 when presenting them to the user.
2893 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
2894 from debug.c --> eval.c
2896 * eval.h, eval.c (scm_eval_options_interface): New options
2898 (SCM_EVAL_STACK): New option: Size of newly created stacks,
2899 i.e. stacks for new threads.
2901 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
2903 * eval.c (unsafe_setjmp): Removed with #if 0.
2905 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
2908 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
2909 to avoid compiler warnings.
2911 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
2913 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
2915 * throw.c (handler_message): Print message on current error port
2916 instead of default error port. (Thanks to Maciej Stachowiak.)
2918 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
2920 * ports.c (scm_add_to_port_table): allocate in units of
2921 struct scm_port_table *, not struct scm_port_table.
2922 * posix.c (scm_close_pipe): remove the port from the port table
2924 Thanks to Rob Engle for both fixes.
2926 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2928 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
2929 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
2931 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2933 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
2935 * backtrace.c (display_error_body, display_backtrace_body),
2936 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
2937 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
2938 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
2939 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
2942 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
2943 don't receive the jmpbuf arg anylonger.
2944 (scm_catch): Don't accept a #f tag.
2945 (scm_throw): Check that key is a symbol.
2946 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
2948 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
2950 * async.c (async_pending): Removed declaration.
2952 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2954 * dynwind.c (scm_wind_chain): New debug function.
2956 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
2957 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
2958 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
2959 extra layer of functions around the body and handler of a thread.
2960 This extra layer makes sure that the handler is called in the
2961 dynamic context of the surround (= empty dynwind list), but under
2962 the *dynamic root* of the body. We can not use the dynamic root
2963 of the surround since that root belongs to another thread => stack
2964 is not handled correctly. It may seem ugly to use this extra
2965 layer, but the extra cost in terms of execution time is really
2966 negligible compared to the total amount of time required to create
2967 a thread, and it would reduce maintainability to duplicate the
2968 crucial and complicated steps performed by cwdr.
2970 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
2971 (SCM_ALLOW_INTS): Added thread switching code before interrupts
2972 get re-enabled. The important effect of this is that interrupts
2973 are blocked during thread switching so that thread data structures
2974 don't risk getting messed up by an unfortunate signal.
2975 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
2976 seems to do more aggressive optimization which actually move
2977 instructions around in these macros in a fatal way. Therefore:
2978 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
2979 just superstitious...)
2980 (SCM_TICK): Maybe do a context switch and take care of asyncs.
2981 This macro should be used instead of SCM_ASYNC_TICK since the
2982 latter doesn't do context switches any more.
2984 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
2985 instead of SCM_ASYNC_TICK.
2987 * coop.c, iselect.c: Since thread switches are now performed with
2988 interrupts masked, we can't use the old mechanism of delivering
2989 signals immediately when they arrive. Signals must instead be
2990 delivered when the asyncs run *after* the end of the critical
2991 section in scm_internal_select. But this also means after context
2992 switch so that the signal will be delivered to a different thread.
2993 To avoid this, I have changed the protocol of
2994 coop_wait_for_runnable_thread and friends so that they are allowed
2995 to return the original thread. So, if a signal arrives during
2996 scm_internal_select, we won't any longer be forced do a context
2997 switch, but can remain in the same thread and deliver the signal
3000 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3001 scm_asyncs_pending and made it global.
3003 * iselect.c: Small fixes.
3005 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3006 coop_condition_variable_init, coop_condition_variable_wait,
3007 coop_condition_variable_signal): Changed return type from `void'
3008 to `int'. This is to adhere closer to the pthreads interface.
3009 This, in turn, is part of an attempt to provide C versions of the
3010 mutex and condition variable primitives which can be part of a
3011 frontend to COOP or pthreads.
3013 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3014 coop_condition_variable_destroy): New functions.
3016 * coop-threads.c (scm_wait_condition_variable): Use
3017 coop_condition_variable_wait_mutex.
3019 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3020 Definitions moved to coop-defs.h.
3022 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3023 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3024 scm_cond_destroy): New C interface to mutecis and cond vars.
3026 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3028 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3030 * iselect.c: Now several threads can wait on the same file
3031 descriptor. The behaviour is compatible with OS select: All
3032 threads waiting for the fd return with the same status.
3034 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3036 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3037 Can spawn a thread from application C code.
3039 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3041 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3042 gh_doubles2scm): New functions.
3044 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3046 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3047 commented-out version of gh_eval_str()
3049 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3051 * socket.c (scm_bind): free soka after use.
3053 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3055 * stime.c (tzvar): new variable.
3056 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3057 avoid memory leaks when allocating.
3059 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3061 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3064 * gc.c, tags.h: Doc fixes.
3066 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3068 * eval.c (macro-eval!): Removed. This function was a design bug.
3069 It allowed memoized code to leak out to the scheme level. Most
3070 things that you could do with `macro-eval!' can be done with
3073 1997-12-20 Tim Pierce <twp@skepsis.com>
3075 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3076 scm_fgets now depends on ftell(3) to know how many bytes were
3079 1997-12-15 Tim Pierce <twp@skepsis.com>
3081 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3082 dealing with strings.
3084 1997-12-13 Tim Pierce <twp@skepsis.com>
3086 Make %read-line more suitable for implementing read-line efficiently.
3087 * ioext.c (scm_read_line): Strip the terminating newline from a
3088 string, and return a cons of the string and its terminator.
3090 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3091 of the string that is read is stored in this memory location.
3092 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3093 * genio.c, genio.h (scm_do_read_line): Update caller.
3094 * ports.h (scm_ptobfuns): Update typedef.
3095 * fports.c (scm_fptob, scm_pipob): Update struct.
3097 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3099 * filesys.c (set_element): Return file descriptor.
3100 (fill_select_type): Return the highest file descriptor.
3101 (scm_select): Tell select about the highest file descriptor. On
3102 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3103 Therefore the extra overhead for calculating the maximum fd seems
3104 to be more than compensated. Is this correct? In any case,
3105 scm_internal_select will be much faster with this info.
3106 (scm_select, fill_select_type, set_element): Don't accept any kind
3107 of object in the file descriptor list or vector.
3109 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3111 * iselect.c (finalize_fd_sets): Bugfix.
3113 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3115 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3116 when using scm_internal_select (since we might switch to another
3119 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3121 * simpos.c (scm_system): always define: use sysmissing if not
3122 available. Check for HAVE_SYSTEM instead of _Windows (does
3123 Windows lack system or does it have an unusable one?).
3124 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3125 Let the argument be optional: if not supplied, call system(NULL).
3127 * ports.c (scm_close_port): relax the type check from OPPORTP to
3128 PORTP; closing a closed port is allowed.
3130 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3132 * fports.c (scm_fgets): Return if the last char in a chunk is
3133 newline. When fgets returns a string whose length is `size-1', it
3134 is ambiguous whether a whole line was retrieved, so we must check
3135 explicitly whether a line terminator is present.
3137 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3139 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3140 before taking the CDR. (Thanks to Harald Meland.)
3142 * filesys.c (scm_stat): Slightly optimized.
3144 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3146 * ports.c (scm_close_port): Make sure the port is open before
3149 * guile-snarf.in: Pass args through to gcc in a way that preserves
3150 whitespace boundaries. (Thanks to Greg Badros.)
3152 1997-12-02 Tim Pierce <twp@skepsis.com>
3154 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3155 statement. (Thanks to Doug Evans for pointing this out.)
3157 1997-12-01 Tim Pierce <twp@skepsis.com>
3159 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3161 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3163 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3164 errno macro expansion of this field name. (errno is a C
3165 preprocessor macro on some systems.)
3167 1997-11-29 Tim Pierce <twp@skepsis.com>
3169 * iselect.c: Doc fix.
3171 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3173 * init.c (scm_start_stack): Removed initialization of
3174 scm_the_last_stack_var.
3176 * backtrace.h: Declare scm_the_last_stack_var.
3178 * backtrace.c: Define scm_the_last_stack_var.
3180 * root.c (mark_root): Don't mark the_last_stack_var.
3182 * root.h (scm_root_state): Removed the_last_stack_var.
3184 * throw.c: Added #include "fluids.h"
3185 (ss_handler): `the-last-stack' is now a fluid.
3187 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3188 --> the_last_stack_fluid.
3190 * backtrace.c: Added #include "fluids.h"
3191 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3192 (scm_backtrace): `the-last-stack' is now a fluid.
3194 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3195 after scm_init_fluids.
3197 1997-11-28 Tim Pierce <twp@skepsis.com>
3199 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3201 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3202 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3204 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3206 * iselect.c (coop_next_runnable_thread,
3207 coop_wait_for_runnable_thread): Disable interrupts so that no
3208 async is executed before a potential error_revive.
3209 (scm_internal_select): Disable interrupts during the parts of the
3210 code which manipulate the sleep queue and the file descriptors.
3212 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3214 * Makefile.am: Added iselect.c and iselect.h.
3216 * coop.c (coop_qinit): Initialize fields used by
3217 scm_internal_select.
3218 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3219 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3220 replacement in iselect.c.
3221 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3222 coop_join): If GUILE_ISELECT enabled, use
3223 coop_wait_for_runnable_thread instead of
3224 coop_next_runnable_thread.
3225 (usleep, sleep): New replacements for system functions if
3226 GUILE_ISELECT is enabled.
3228 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3230 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3232 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3233 iselect.h. Implement Scheme level `select' using
3234 scm_internal_select. (See NEWS.)
3236 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3238 * init.c: Call scm_init_iselect.
3240 * iselect.h, iselect.c: New files. Implements
3241 scm_internal_select. (See NEWS.)
3243 1997-11-27 Tim Pierce <twp@skepsis.com>
3245 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3246 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3247 and scm_must_free, since ultimately the string returned will be copied
3248 by scm_makfrom0str anyway. Also, read any characters that may have
3249 been pushed onto the port with scm_ungetc.
3250 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3251 * ioext.c (scm_read_line): Free string after Guilifying it.
3252 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3254 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3256 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3258 * gh.h: Safely wrap prototypes for c++ usage.
3260 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3262 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3263 gh_repl (argc, argv).
3265 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3267 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3268 and to invoke scm_shell().
3269 (gh_launch_pad): took out the loading of boot-9.scm from here,
3270 since it is probably best to let the user control that. In fact,
3271 gh_repl() now invokes scm_shell() which does that.
3273 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3275 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3278 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3281 yesterday's underscore patch. (Thanks to Marius Vollmer for
3284 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3286 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3287 DLSYM_ADDS_USCORE is not defined.
3289 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3291 * gh_data.c (gh_uniform_vector_length):
3292 (gh_uniform_vector_ref): started implementing the uniform types in
3295 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3297 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3298 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3300 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3302 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3303 configure.in was changed).
3305 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3307 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3308 * Makefile.in: Regenerated.
3310 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3312 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3313 OPORT is an `open' port, not an output port.
3315 * filesys.c (scm_close, set_element, get_element, scm_chown,
3316 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3317 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3318 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3319 scm_close_port, scm_port_line, scm_set_port_line_x,
3320 scm_port_column, scm_set_port_column_x, scm_port_filename,
3321 scm_set_port_filename_x, scm_port_mode,
3322 scm_close_all_ports_except, scm_set_current_output_port,
3323 scm_set_current_error_port): Likewise
3324 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3325 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3327 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3328 * backtrace.c (display_backtrace_body): Likewise
3329 * fports (scm_setvbuf): Likewise
3330 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3331 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3332 scm_getpeername, scm_send, scm_sendto): Likewise
3333 * unif.c (scm_uniform_array_write): Likewise
3335 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3337 Minor problems with substring-related tag changes.
3338 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3339 exactly what we want to leave in to detect substrings.
3340 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3341 * tags.h: Fix diagrams and comments describing the S tag bit;
3342 remove vestigial remarks about the D tag bit.
3343 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3344 * strings.c: Formatting tweaks.
3346 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3347 variable first; then SCHEME_LOAD_PATH, with a warning message.
3348 (scm_parse_path): New function.
3349 * script.c: Doc fixes.
3351 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3353 Readline support, from Daniel Risacher.
3354 * readline.c, readline.h: New files.
3355 * init.c: #include "readline.h".
3356 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3357 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3358 * Makefile.in: Regenerated.
3359 * scmconfig.h.in: Regenerated, after change to ../configure.
3361 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3363 * gh.h: gh_vector_set -> gh_vector_set_x
3365 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3367 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3368 with the ! -> _x mapping when going from Scheme to C.
3370 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3372 * gh.h (gh_reverse):
3380 (gh_assoc): added these gh_ functions implemented as macros.

3383 (gh_string_equal_p): added these two missing predicates.
3385 * gh_list.c (gh_append):
3390 (gh_set_cdr_x): added these routines as I go through and try to
3391 complete the picture R4RS functions that should be mirrored in the
3394 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3396 * tags.h (scm_tc7_substring): Changed the comment and code to
3397 conform with the changes below. Folks! We have suddenly two new
3398 free tc7 codes!!! Jummy, jummy!
3400 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3402 * Makefile.in: Rebuilt.
3403 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

3422 (SCM_TYP7D): Removed.
3423 (scm_tc7_mb_string): Removed.
3424 (scm_tc7_mb_substring): Removed.

3427 Don't include "mbstrings.h".
3428 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3429 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3431 Don't include "mbstrings.h".
3432 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3433 (SCM_SYMBOL_SLOTS): Define as 4.
3434 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

3456 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3458 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3460 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3462 * gh_test_c.c (c_vector_test): some improvements on the vector
3465 * gh.h (gh_vector): this used to exist but do the wrong thing.
3466 Now it (almost) does the right thing, though it takes a list
3467 instead of the individual arguments. I need to see how it could
3469 (gh_list_to_vector): added this function as a macro. Corresponds
3470 to Scheme's (list->vector ...).
3471 (gh_vector_to_list): added this function as a macro. Corresponds
3472 to Scheme's (vector->list ...).
3474 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3475 gh_vector_ref, so that it resembles the Scheme routines more.
3476 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3477 resembles the Scheme routines more.
3478 (gh_make_vector): this used to be (stupidly) called gh_vector().
3479 This is the right name, since it does the same thing as the Scheme
3480 (make-vector ...) procedure.
3482 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3484 * ports.h: #include "libguile/print.h"

3487 Some indentation fixes.
3489 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3490 longer a user field; New field: class_flags.
3492 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3494 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

3497 gh_int2scmb(), which is now tagged as obsolete.
3499 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3501 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3502 macros should by convention not test for NIMPness.)
3503 (SCM_COERCE_OPORT): Adjust indentation.
3505 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3506 SCM_NIMP test before SCM_PRINT_STATE_P.

3513 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3515 * struct.c (scm_print_struct): Use new printer slot; Default
3516 printing: Also output hex code of vtable so that type identity
3517 will be indicated as well.
3518 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3519 Removed struct_printer_var; Removed struct-vtable-offset;
3520 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3521 vtable-offset-user): New constants.
3523 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3524 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3525 If this slot contains a procedure, use that to print structures of
3526 the type represented by this vtable.
3528 * print.c (scm_iprin1): Don't print arguments of macro
3529 transformers. (They are always: exp env.); Bugfix: Unmemoize
3530 transformer source with correct environment.
3532 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3534 Streamlining of call-with-dynamic-root:
3536 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3537 there is now only one catch.
3538 (cwdr_outer_body): Removed.
3539 (cwdr_handler): New function.
3540 (scm_internal_cwdr): New function to perform the function of cwdr
3541 but take args that are more useful to C code. Also, the handler
3542 is now invoked *outside* of the new dynamic root, like the docs
3543 say. We no longer have to catch absolutely all errors, the caller
3544 is responsible for using a handler that does not throw, if he
3546 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3547 * root.h (scm_internal_cwdr): New prototype.
3549 Even more but risky streamlining:
3551 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3552 allocation of the jumpbuf of a root continuation. The changes
3553 below are controlled by it. They are now deactivated.
3554 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3555 the JMPBUF of the scm_rootcont to NULL before returning.
3557 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3558 when they are non-NULL.
3559 (scm_gc_mark): Likewise, mark only when non-NULL.
3561 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3562 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3564 * gc.c (scm_done_malloc): New function.
3565 gc.h (scm_done_malloc): New prototype.
3567 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3568 (struct scm_print_state) [revealed]: New field.
3569 (scm_print_state_vtable): Make visible to the outside world for
3570 type checking purposes.
3571 (scm_valid_oport_value_p): New prototype.
3573 * print.c (scm_valid_oport_value_p): New function to check whether
3574 a certain value is acceptable as a port argument.
3575 (scm_print_state_vtable): New variable.
3576 (scm_free_print_state): Set `revealed' field to false.
3577 (scm_iprin1): Call user supplied closure printer with
3578 scm_printer_apply. Print in the traditional way when there isn't
3579 one or when it returns #f.
3580 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3581 Accept a port/print-state pair in addition to just a port.
3582 (scm_prin1): Don't return the print_state to the pool when it has
3584 (scm_printer_apply): Set `revealed' field of print_state to true.
3585 (scm_init_print): Set scm_print_state_vtable.
3586 (print_state_fluid, print_state_fluid_num): Removed.
3588 * throw.h (scm_handle_by_proc_catching_all): New prototype
3589 throw.c (scm_handle_by_proc_catching_all): New function
3591 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3593 * Makefile.in: Regenerated with automake 1.2c.
3595 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3597 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3598 was looping endlessly.
3600 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3602 * strports.c (scm_eval_string): Don't close the port.
3604 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3605 former returns a nice normal integer. (Thanks to Daniel
3608 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3610 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3611 makefile variable as a build parameter called LIBS. The
3612 build-guile program will use this, for the time being.
3613 * Makefile.in: Regenerated.
3615 Thanks to Shiro Kawai:
3616 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3617 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3620 * Makefile.in: Regenerated with automake 1.2a.
3622 * script.c (scm_compile_shell_switches): If we hit the -c or --
3623 arguments, don't set the car of (command-line) to scm_usage_name,
3624 the prettified name of the guile executable; give it the full
3625 path, the way shells usually handle $0.
3627 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3629 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3630 Scheme-level name `array-map' and renamed `serial-array-map' to
3631 `serial-array-map!'.
3633 * backtrace.c: Introduced exception handlers which now enclose
3634 `display-error' and `display-backtrace' so that error reporting
3635 won't get into infinite loops if an error occurs during displaying
3636 of the error. This can very easily happen with user supplied
3637 print call-back routines.
3639 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3641 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3642 the names `serial-array-map' and `array-map' should be removed.)
3644 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3646 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3647 Added #include "objects.h"
3649 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3650 Add #include "feature.h".
3652 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3653 (modinclude_HEADERS): Added objects.h.
3655 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3656 This test is needed at many places in the code and should be
3657 abstracted. (Motivated by the need of this test in libguiletk.)
3659 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3660 (scm_eval_string), load.c (scm_primitive_load,
3661 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3662 Use SCM_EOF_OBJECT_P.
3664 * eval.c (scm_init_eval): Add feature `delay'.
3666 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3668 * scmhob.h: Removed.
3670 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3672 * list.h (SCM_LISTn): New macros. Make list creation in C code
3673 prettier. The idea comes from STk.
3675 * sequences.h, sequences.c, append.h, append.c: Removed. These
3676 files implemented non-R4RS operations which would encourage
3677 non-portable programming style and less easy-to-read code.
3679 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3682 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3683 sequences.h, #include append.h.
3685 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3688 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3690 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3692 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3694 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3696 * eval.c: Added #include "objects.h"
3698 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3701 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3702 adjacent smob numbers.
3704 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3706 * procprop.h: Added declaration of scm_i_inner_name.
3708 * gsubr.c: New global symbol scm_i_inner_name.
3710 * debug.c (scm_procedure_name): Try procedure property
3711 `inner-name' if `name' fails.
3713 * print.c (scm_iprin1): Use scm_macro_name.
3715 * eval.c (scm_m_define): Give names to macros as well; Only the
3716 first top-level definition gives a procedure/macro a name.
3717 Otherwise confusing names can turn up in backtraces.
3718 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3719 `name'; Give names to macros as well.
3721 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3722 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3725 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3727 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3729 (prinmacro): Removed. The code has been moved/merged into print.c
3730 in order to decrease code redundancy. We want macros to print in
3731 a way equivalent to procedures, and it would be silly to duplicate
3732 the required code. (We don't want to maintain two places.)
3733 (macrosmob): Print field is now a NULL pointer.
3735 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3736 scm_macro_transformer): New prototypes.
3737 (scm_tc16_macro): Declared.
3739 * print.c (scm_iprin1): Added code for printing of macros. Macros
3740 are now printed in a way equivalent to procedures.
3742 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3744 * procs.h (scm_closure_p): Added declaration.
3746 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3748 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3749 Shouldn't pass "heap" as the subr name.
3751 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3753 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3754 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3755 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3756 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3757 SCM_BOOL_T. Any non-false value is true.
3759 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3761 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3762 scm_gensym): Added prototypes.
3764 * symbols.c (scm_gensym): New function. This will speed up
3765 certain types of applications (such as macro systems) which
3766 generate lots of symbols.
3768 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3770 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
3772 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
3774 * unif.c (scm_shap2ra): tighten the checking of the array dimension
3775 specifier, since (2) or (2 . 3) would cause SEGV.
3776 (scm_transpose_array): more argument checking fixes.
3778 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
3780 * Makefile.in: Regenerated.
3782 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
3784 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
3786 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3788 * error.c, error.h (scm_error_callback): Removed (see NEWS).
3790 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
3792 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
3793 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
3796 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
3797 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
3798 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
3799 scm_array_p, scm_array_rank, scm_array_dimensions,
3800 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
3801 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
3802 scm_array_prototype): Added case scm_tc7_wvect.
3804 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
3806 * errno.h: prototype for scm_strerror.
3807 * error.c (scm_strerror): new procedure.
3809 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3811 * list.c (scm_list_append_x): Allow non-pair as last argument.
3812 This is consistent with the R4RS append and is probably the
3813 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
3815 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
3817 * stime.h: prototype for scm_times.
3818 * stime.c (scm_times): new procedure.
3819 * ioext.c (scm_fseek): if the first argument is a file descriptor
3821 (scm_ftell): if the first argument is a file descriptor call lseek
3823 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
3824 * filesys.c (scm_chmod): if the first argument is a file descriptor,
3826 (scm_chown): if the first argument is a port or file descriptor,
3828 (scm_truncate_file): new procedure.
3829 Add DEFER/ALLOW INTS to a few other procedures.
3830 (scm_fsync): new procedure.
3831 (scm_open_fdes): new procedure.
3832 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
3834 (scm_fcntl): the first argument can now be a file descriptor. The
3835 third argument is now optional.
3837 * posix.c (scm_execl, scm_execlp): make the filename argument
3838 compulsory, since omitting it causes SEGV.
3839 (scm_sync): return unspecified instead of #f.
3840 (scm_execle): new procedure.
3841 (environ_list_to_c): new procedure.
3842 (scm_environ): use environ_list_to_c. disable interrupts.
3843 (scm_convert_exec_args): take pos and subr arguments and
3844 improve error checking.
3846 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3848 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
3849 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
3850 argument to SCM_ASSERT. Furthermore, the name of the function
3851 should be passed as first argument when signalling
3852 SCM_WNA. (Thanks to Thomas Morgan)
3854 * gsubr.c (scm_gsubr_apply): From Radey Shouman
3855 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
3856 dispatches on the number of actual args has a default case
3857 reporting an internal error. This is a vestige from a version
3858 that mallocated a SCM vector to hold the arguments. In the
3859 current version this check is too late: if it ever happens we will
3860 have already overstepped the bounds of the array.
3862 Also, the patch [...] adds a check for too many actual arguments."
3864 mdj: Removed check for "internal programming error".
3866 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3868 * gh_io.c (gh_write): New function.
3870 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
3871 throw.c (scm_internal_stack_catch): New sibling to the other catch
3872 functions. Code moved from gh_eval.c.
3873 throw.h: Added header.
3874 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
3875 scm_internal_stack_catch.
3877 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3879 * ioext.h: fix up prototypes.
3880 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
3881 Scheme name is now dup->fdes.
3882 (scm_dup_to_fdes): make the second argument optional and
3883 fold in the functionality of scm_primitive_dup.
3884 (scm_primitive_dup): deleted.
3886 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3888 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
3889 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
3890 ultrix are defined. Use setvbuf instead of setbuf.
3891 (scm_setvbuf): new procedure.
3892 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
3893 (scm_setfileno): moved from ioext.c.
3894 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
3895 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

3905 state as nested data while they are printed.
3906 (print_state_fluid, print_state_fluid_num): New variables.
3907 (scm_init_print): Initialize them.
3908 (scm_iprin): If print_state_fluid carries a print_state, use that
3909 instead of creating a new one.
3910 (scm_printer_apply, apply_stub, struct apply_data): New
3911 definitions to help with calling printer functions written in
3913 * print.h (scm_printer_apply): New prototype.
3915 * struct.c (scm_print_struct): Use scm_printer_apply to call the
3916 user defined struct printer.

3924 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
3926 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
3927 SCM_ASSERT: arg comes before pos.
3929 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3931 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
3932 to a list of length zero correctly.
3934 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3936 Supply an `fgets' method for port objects to do fast line i/o.

3950 * ioext.h: removed scm_duplicate_port prototype.
3952 * ioext.c (scm_primitive_dup2): return the new file descriptor
3953 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
3955 (scm_fdopen): bug fix: don't try to make port unbuffered until its
3956 stream has been set.
3957 (scm_duplicate_port): deleted, there's now an implementation in
3959 (scm_primitive_dup2): do nothing if newfd == oldfd.
3961 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
3963 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
3966 * ioext.h: new prototypes.
3967 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
3969 * fluids.c (next_fluid_num): don't do
3970 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
3972 * ports.h: prototypes too.
3973 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
3975 * fports.h: prototype too.
3976 * fports.c (scm_evict_ports): moved from ioext.c.

3983 * filesys.h: scm_close prototype.
3984 * filesys.c (scm_close): new procedure, can close file descriptors
3985 and ports (scsh compatible).
3987 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
3990 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
3992 * fluids.c, fluid.h: New files.
3993 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
3994 (modinclude_HEADERS): Added "fluids.h"
3996 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
3997 scm_init_fluids to initialize the fluid machine.
3998 (scm_start_stack): Initialize the fluids of the first root with
3999 scm_make_initial_fluids.
4001 * root.h: Added "fluids" member to scm_root_state.
4002 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
4003 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4004 unique for the new root when it has a parent.
4006 * smob.h: Include "libguile/print.h" to make scm_print_state
4009 * dynl.c (free_dynl_obj): New function to free the dynamic object
4010 data. (dynl_smob): Use it.
4011 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4012 the dynamic object data below the linking of the object to avoid
4013 memory leak when the linking code throws an error. Now the code
4014 leaks a whole dynamically linked library when must_malloc throws,
4015 but that should be much less likely.
4017 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4019 Changes to compile under gnu-win32, from Marcus Daniels:
4020 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4021 (scm_localtime): Change SCM_EOF to SCM_EOL.
4022 (scm_mktime): Likewise.
4023 * socket.c: Don't include sys/un.h unless autoconf tells
4024 us Unix domain sockets are available.
4025 (scm_fill_sockaddr): Ignore Unix domain code.
4026 (scm_addr_vector): Likewise.
4027 (scm_init_addr_buffer): Likewise.
4028 (scm_socketpair): Don't include unless socketpair was
4029 found during autoconf.
4030 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4031 * scmsigs.c (scm_pause): Don't include unless pause was found
4033 * posix.c (scm_getgroups): Don't include unless support function
4034 was found during autoconf (in this case, getgroups).
4035 (scm_setpwent): For setpwent.
4036 (scm_setegid): For setegid.
4037 * net_db.c (scm_inet_netof): Don't include unless support
4038 function was found during autoconf (in this case, inet_netof).
4039 (scm_lnaof): For inet_lnaof.
4040 (scm_inet_makeaddr): For inet_makeaddr.
4041 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

4045 (scm_setnet): For setnetent, endnetent.
4046 (scm_setproto): For setprotoent, endprotoent.
4047 (scm_setserv): For setservent, endservent.
4048 * scmconfig.h.in: Regenerated.
4050 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
4052 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4053 scm_misc_error, not SCM_EOF.
4055 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4056 arguments for formatting the error message, not SCM_BOOL_F. I
4057 think this is left over from the (eq? '() #f) days.
4059 * read.c (recsexpr): Give this a dummy definition if
4060 DEBUG_EXTENSIONS isn't #defined.
4062 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4064 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
4067 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
4069 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
4072 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
4074 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4075 alloca.lo will be included in @LIBLOBJS@. Something better than
4076 this should be possible.
4077 * Makefile.in: Regenerated.
4079 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4081 * simpos.h: prototype for scm_primitive_exit.
4082 * simpos.c (scm_primitive_exit): new procedure, terminates the
4083 process without unwinding the stack.
4085 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4087 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4088 argument and logior its components together, so the user doesn't
4089 have to do this explicitly. Also, if regexp/basic is supplied, then
4090 turn off REG_EXTENDED.
4091 (scm_init_regex_posix): New regexp/basic symbol.
4092 (REG_BASIC): #define this if it is not already present.
4094 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4096 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
4097 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
4098 (CLEANFILES): New target, clean versiondat.h, libpath.h.
4099 (DISTCLEANFILES): New target, clean *.x.
4100 * Makefile.in: Regenerated.
4102 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
4104 * script.c (scm_compile_shell_switches): Add 1997 to copyright
4105 years in usage message.
4107 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
4108 * Makefile.in: Regenerated.
4110 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4111 flag; I don't think we support it.
4112 (scm_make_regexp): Make sure the user doesn't pass the
4115 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4117 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4118 name them according to the SCSH convention: regexp/mumble.
4120 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4122 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
4124 * Makefile.am (libpath.h): Include the values of all the standard
4125 Makefile directory variables. Print a message, but don't print
4127 (versiondat.h): Print a message, but don't print all the commands.
4128 * load.c: #include "alist.h".
4129 (init_build_info): New function.
4130 (scm_init_load): Call it.
4131 * Makefile.in: Regenerated.
4133 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4135 * root.c: Establish a reliable catch-all handler for the new root.
4136 After all the Scheme handler function might signal an error too,
4137 and we don't want to lose that.
4138 (cwdr_inner_body): Renamed from cwdr_body.
4139 (cwdr_outer_body): New function, to establish the user's handler,
4140 and pass control to cwdr_inner_body.
4141 (cwdr): Establish the reliable catch-all handler here, and pass
4142 control to cwdr_outer_body.
4143 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4144 the user's handler through to cwdr_outer_body.
4145 * throw.c (scm_handle_by_message): Move guts into....
4146 (handler_message): New static function.
4147 (scm_handle_by_message_noexit): New function.
4148 * throw.h (scm_handle_by_message_noexit): New prototype.
4150 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4151 across this. Only works on GCC. Otherwise, we hope for the best.
4152 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4153 the feeling that real thread systems will not need this...
4155 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4157 Try to detect when people are using one version of libguile and a
4158 different version of ice-9. People have been skewing things and
4159 sending in bug reports.
4160 * Makefile.am (versiondat.h): New file to generate.
4161 * version.c: #include "versiondat.h", to get version info.
4162 (scm_libguile_config_stamp): New function.
4163 * script.c: #include "version.h".
4164 (scm_compile_switches): Call scm_version to get version number.
4165 * scmconfig.h.in, Makefile.in: Regenerated.
4166 * Makefile.in: Regenerated.
4168 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4169 primitive definitions under their Scheme names.
4171 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4172 1:2. Helps avoid confusion between installed and uninstalled libs.
4174 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4177 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4178 backslash from definition; this should be used like: GDB_INTERFACE;
4180 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4182 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4183 new port unbuffered until its stream has been set.
4185 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4187 * ports.h: new prototype.
4188 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4190 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4192 Make things compile neatly under Sun's C compiler.
4193 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4194 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4195 unsigned, because that's what the ANSI function takes.
4196 * extchrs.h (xmbtowc): Corresponding change to prototype.
4197 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4199 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4200 argument plain char *.
4201 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4203 * tag.c (scm_tag): Remove unreachable statement.
4204 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4205 top of the word, it should be unsigned.
4207 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4208 is defined, to avoid warnings; it's only used in the
4209 conflict-checking code. Which might go away anyway.
4210 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4211 conditionals; put the label definition in an #if too, to stifle
4214 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4215 ChangeLog-threads in the distribution.
4216 * Makefile.in: Regenerated.
4218 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4220 * guile-snarf.in: Changed regexp to support CPPs that insert
4221 whitespace between lexical tokens (which munges the `%%%' snarf
4224 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4226 * load.c (scm_init_load_path): Append $(datadir)/guile to
4227 %load-path, so modules do not have to be installed in Guile's
4228 current version directory.
4230 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4232 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4233 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4234 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4235 call the sysdep functions with deferred ints.
4236 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4237 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4238 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4241 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4244 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4246 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4248 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4250 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4253 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4255 * eval.c (scm_lookupcar1): New procedure to cope with a race
4256 condition during lookup (when using threads).
4257 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4258 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4261 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4263 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4264 supplied. (Change from Tim Pierce.)
4266 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4268 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4269 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4270 default and not `()'. `#f' is the canonical non-value in Scheme,
4273 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4275 * struct.c (struct_printer): New variable that holds a handle on
4276 the Scheme variable *struct-printer*. This variable can be set by
4277 Scheme code to override the printing of structures.
4278 (scm_print_struct): If struct_printer is set, call it. If it is
4279 not set, or returns #f, print the structure in the old fashion.
4280 Include "eval.h" for scm_apply.
4282 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4284 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4285 scm_struct_i_n_words to get the number of fields, not
4286 -scm_struct_n_extra_words.
4288 On the route to fancier struct printing:
4289 * struct.c (scm_print_struct): New function to print a structure.
4290 Include "genio.h" to support it. This function doesn't do
4291 anything interesting right now, but I think it should be here
4293 * struct.h: Include "print.h" and add prototype for
4295 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4296 print structures ourself.
4298 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4300 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4301 before applying the handler in case it doesn't return.
4303 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4305 * scmsigs.h, async.h: updated.
4307 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4310 * posix.c (scm_uname): interpret only negative values as an error.
4311 Solaris normally returns a positive value.
4313 * script.c (scm_compile_shell_switches): if we are not going into
4314 an interactive repl, set scm_mask_ints to zero so that asyncs can
4317 * simpos.c (scm_system): don't ignore/unignore signals around
4320 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4323 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4324 done in boot-9.scm instead.
4326 * scmsigs.c, async.c: Major rewriting of signal handling code.
4327 (scm_sigaction): new procedure.
4328 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4330 (scm_raise): return unspecified, throw error on failure.
4332 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4334 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4335 feature, to help boot-9.scm decide whether to import the regex
4338 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4340 * eval.c: Include scmconfig.h at the beginning of the file so that
4341 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4344 * regex-posix.c: #include "_scm.h" before conditionally #including
4345 <regex.h>; the former defines HAVE_REGCOMP.
4347 * regex-posix.c: #include <regex.h> conditionally, so the file is
4348 CPP'able (for dependency scanning) even on systems that don't have
4351 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4353 Add new R4RS-compliant syntax for keywords.
4354 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4355 regardless of the setting of the `keywords' read option.
4356 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4357 can be re-read no matter what the setting of the `keywords' read
4360 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4362 Add support for POSIX regular expressions.
4364 * regex-posix.c, regex-posix.h: New files. (Some code
4365 is taken liberally from rx/rgx.c in the old Guile dist.)
4367 * init.c: Include regex-posix.h.
4368 (scm_boot_guile_1): Call scm_init_regex_posix.
4370 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4371 Add regex-posix.[ch] sources.
4372 * Makefile.in: Regenerated.
4374 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4375 to do this automatically? It didn't for me, bleh.)
4377 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4379 * fports.c (print_pipe_port): New function.
4380 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4381 latter doesn't even take the right arguments.
4383 * Makefile.am: Increment shared lib revision number. I think
4384 sometimes the uninstalled Guile finds the installed shared lib;
4385 Gord says doing this might help. As things turned out, I can't
4386 say whether it does.
4387 * Makefile.in: Regenerated.
4389 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4390 passing it as the closure argument to scm_boot_guile. (Bill
4393 * ports.c (print_void_port, putc_void_port, puts_void_port,
4394 write_void_port, flush_void_port, getc_void_port, close_void_port,
4395 noop0): Use ANSI prototypes instead of K&R declarations, so the
4396 initialization of void_port_ptob gets aggressively type-checked.
4397 Fix arguments of print_void_port and write_void_port. (Bill

4433 * script.c (scm_find_executable): Use prototype-style definition
4434 here; apparently it's not quite right to have const in a prototype
4435 and then use a K&R declaration. I wonder if stuff like this will
4436 go away if we compile with -Wrequire-prototypes, or whatever that
4437 is... (Bernard URBAN)
4439 * scmhob.h: New text from Bernard URBAN.
4441 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4443 * script.c: Don't #define const on hpux. Configure takes care of
4444 this. (Thanks to Larry Schwimmer.)
4446 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4447 decide whether to #include <unistd.h>, instead of listing a bunch
4448 of systems. Don't #include stdio twice. Removed dyked-out
4449 definition of scm_find_impl_file.
4451 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4453 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4454 library version info to 1:0.
4455 * Makefile.in: Regenerated.
4457 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
4458 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,

4460 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
4461 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4462 throw.c: Update copyright years; these files have been worked on
4463 significantly in 1997, but only had copyright years for 1996.
4464 Also, change name of copyright holder on some from Mikael
4465 Djurfeldt to Free Software Foundation; he has signed papers
4466 assigning the changes to the FSF.
4468 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4469 reason not to give the user the option.
4471 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4472 Return #f on end-of-file when scanning table (i.e. when called
4473 with no arguments). Try to catch errors, when we can.
4474 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4476 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4477 external declarations. These are useful.
4479 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4481 * posix.c: don't include <sys/select.h> or define macros for
4482 select, since they were not used in this file.
4484 * filesys.c (scm_select): make the fifth parameter microseconds,
4485 not milliseconds. let the fourth parameter be either a real value
4486 or an integer or #f. The first, second and third arguments can
4487 now be vectors: the type of the corresponding return set will be
4489 (set_element, get_element): new static procedures.
4491 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4493 * strports.c (scm_eval_string): New function.

4498 * net_db.c (h_errno): Add extern decl for this.
4500 * fports.c (local_pclose): New function.
4501 (scm_pipob): Use it in the initializer here.
4504 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4505 Use a meaningful error message when signalling an error. For
4506 this, scm_gethost must check h_errno rather than errno.
4508 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4510 * Makefile.in: Regenerated, using automake-1.1p.
4512 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4514 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4515 not SCM_UNSPECIFIED.
4517 * script.c (scm_compile_shell_switches): don't append (quit) if
4519 (scm_shell): call scm_exit_status and exit on the result of the
4522 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4524 Ensure that shared substrings are handled properly when passed to
4525 a system call or other foreign function. Many thanks to Tim
4527 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4528 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4529 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4530 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4531 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4532 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4533 (scm_display_error_message): use RO macros when strings may be RO.
4534 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4535 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4536 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
4537 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
4538 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
4539 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
4540 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4541 scm_strftime), vports.c (scm_make_soft_port): use
4542 SCM_COERCE_SUBSTR to make sure shared substrings are

4547 * error.c (scm_error): Add newline to error message.
4549 * init.c (scm_init_standard_ports): Doc fix.
4551 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4553 * dynl-shl.c: Completely replaced with new code from Bernard
4556 * script.c (scm_ice_9_already_loaded): New variable.
4557 (scm_compile_shell_switches): Use it.
4559 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4561 * filesys.c (scm_input_waiting_p): add missing third argument to
4564 * stime.c (scm_localtime): copy the result of localtime before
4565 calling gmtime in case they share a buffer.
4566 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4569 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4571 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4573 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4575 * Makefile.am (check-local): New target, which causes 'make check'
4576 to run gh_test_c and gh_test_repl, with some trivial input.
4577 * Makefile.in: Rgnrtd.
4579 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4581 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4584 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4586 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4587 sure how this was supposed to work.
4588 (scm_async_click): don't send SCM_TICK_SIGNAL.
4589 (scm_init_async): don't initialize %tick-thunk.
4591 * the following change doesn't affect the Scheme interface:
4592 gc-thunk is called at the end of garbage collection. however it's
4593 no longer implemented by pretending it's a signal.
4595 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4596 system async corresponding to scm_gc_thunk.
4597 * async.h: declare scm_gc_async.
4598 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4599 gc-thunk directly, instead of going through a signal handler.
4600 (scm_gc_async): new variable, points to the GC system-async.
4601 (scm_init_async): save the GC async as scm_gc_async instead
4602 of using system_signal_asyncs.
4603 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4605 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4607 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4608 Don't screw up if we're interrupted.
4609 * Makefile.in: Regeneradet.
4611 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4613 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4615 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4616 we're not using AM_INIT_GUILE_MODULE any more.
4617 * Makefile.in: Reneregated.
4619 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4621 Functions for finding variable bindings, grace à Tim Pierce.
4622 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4623 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4625 Get 'make dist' to work again.
4626 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4627 * Makefile.in: Regenerated, like a surry without a fringe on top.
4629 Changes for reduced Guile distribution: one configure script,
4631 * configure.in, configure: Removed.
4632 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4633 real configure script lives.
4634 * Makefile.in, scmconfig.h.in: Regenerated.
4636 * init.c: #include "script.h", to get prototype for script.c's
4639 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4641 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4642 scm_must_malloc, not raw malloc.
4644 * script.c (scm_compile_shell_switches): Dyke out debugging output
4647 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4649 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4651 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4652 system has them. Hope this is safe. Previously
4653 sys/timeb.h was included if HAVE_FTIME was defined or if
4654 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4655 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4657 * ioext.c (scm_setfileno): add missing third argument to
4658 scm_misc_error call.
4660 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4662 * eq.c (scm_equal_p): Correctly compare strings of different
4663 varieties. (Thanks to Tim Pierce.)
4665 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4667 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4668 #! block comment must occur on a line all by itself.
4670 Move most of the guts of shell command processing into libguile,
4671 so guile.c can be very small (and eventuallly auto-generated. (I
4672 mean, generated mechanically, not self-generated. Hmm.))
4673 * guile.c, script.c, script.h: New source files.
4674 * init.c (scm_boot_guile_1): Call scm_init_script.
4675 * libguile.h: #include "script.h".
4676 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4677 targets, for new executable.
4678 (libguile_la_SOURCES): Mention script.c.
4679 (modinclude_HEADERS): Add script.h.
4680 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4681 not dynamic linking is enabled. This is because we're generating
4682 executables now. Move CY_AC_WITH_THREADS call after those, so the
4683 values of cy_cv_threads_libs captures the libs chosen above.
4684 * Makefile.in, configure, aclocal.m4: Regenerated.
4686 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4687 We don't maintain this interface any more, and it just confuses
4690 * alloca.c: #include <scmconfig.h>, not <config.h>.
4691 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4692 it'll get included in disties.
4694 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4696 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4697 be distributed, because they confuse people.
4698 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4700 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4702 * configure.in: check for presence of gethostent (not present on
4703 OpenBSD by default).
4704 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4705 * configure, scmconfig.h.in: Regenerated.
4707 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4709 * backtrace.c (scm_backtrace): Split message string across
4710 newlines properly. GCC is more tolerant of this than other
4713 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
4715 Merge threads directory into libguile.
4716 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4717 threads.h: New source files.
4718 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
4719 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
4721 (modinclude_HEADERS): Add threads.h, coop-defs.h.
4722 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4723 coop-threads.c.cygnus, coop-threads.h.cygnus.
4724 * configure.in: If we're using threads, include threads.o in
4726 * _scm.h, libguile.h: threads.h lives in this directory now.
4727 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4728 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4729 currently used, but brought along for information's sake.
4730 * ChangeLog-threads: log from old 'threads' directory.
4731 * Makefile.in, configure: Rebuilt.
4733 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4735 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
4738 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
4740 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
4742 Merge GH interface library into libguile.
4743 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
4744 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
4745 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
4746 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4748 (EXTRA_libguile_la_SOURCES): ... here.
4749 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4750 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4751 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4752 New variables, describing how to build the gh test programs.
4753 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4754 build the test programs, and we probably should have been linking
4755 libguile.la against them all along, to support AIX shared libs.
4756 Add cflags for threads to CFLAGS; add libs for threads to new
4757 variable THREAD_LIBS, used in Makefile.am.
4758 * ChangeLog-gh: log from old `gh' subdirectory.
4759 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4761 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4763 * acconfig.h: Undo change of Apr 9; including the definition of
4764 PACKAGE in the guile headers conflicts with applications' own
4766 * scmconfig.h.in: Regenerated.
4768 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

4775 when PROC is receiving no arguments.
4777 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
4779 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
4780 have S_IFSOCK. This is the case under Ultrix.
4782 * posix.c (scm_status_exit_val, scm_status_exit_val,
4783 scm_status_term_sig, scm_status_stop_sig): Modified to work with
4784 Ultrix versions of WIFSTOPPED, etc., which assume that their
4785 arguments are lvalues (hmm).
4787 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
4789 * eval.c: Doc fixes.
4791 * throw.c: Doc fixes; rearranged.
4793 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

4797 * acconfig.h: Added entry for PACKAGE.
4798 * scmconfig.h.in: Regenerated.

4801 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
4802 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

4806 * Makefile.in: Rebuild.
4808 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
4810 * stime.c (scm_mktime): take an optional zone argument.
4811 (scm_localtime): check putenv return value.
4812 (scm_strftime, scm_strptime): moved from posix.c. move #include
4814 stime.h, posix.h: update prototypes.
4815 (bdtime2c, setzone, restorezone): new static procedures.
4816 (scm_mktime, scm_strftime): use them.
4817 (scm_strftime): don't call mktime before strftime. Use
4818 filltime for return value.
4819 (filltime): convert NULL zname to #f.
4820 (scm_strptime): return a count of characters consumed, not
4821 the remaining string.
4823 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4825 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

4828 Uncomment localtime and mktime.
4830 * configure.in: add AC_STRUCT_TIMEZONE.
4832 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4834 * stime.c (scm_init_stime): don't define ticks/sec.
4835 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
4836 return value problem and is still portable.)
4838 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
4840 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4841 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
4842 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
4843 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
4844 cpp_err_symbols.c): Corresponding changes.
4845 * Makefile.in: Regenerated.
4847 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
4849 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4850 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
4851 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
4852 * putenv.c: new file, from sh-utils 1.12.
4854 * posix.c (scm_environ): use malloc in place of scm_must_malloc
4855 since allocation isn't for Scheme objects.
4856 (scm_putenv): copy strings before placing in the environment.
4858 * stime.c (scm_current_time): throw an error if time returns -1,
4859 instead of returning #f.
4860 (scm_get_internal_real_time, scm_get_internal_real_time): use
4861 scm_long2num for return value instead of SCM_MAKINUM.
4863 * stime.h: prototypes updated.
4865 * stime.c (scm_time_in_msec): apparently unused, deleted.
4867 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4869 * configure.in: check for gettimeofday.
4871 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
4872 which may be more usefully portable than a gettimeofday interface.
4874 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
4876 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

4882 * stime.c (filltime): recovered static procedure.
4883 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
4886 * posix.h: add prototype for scm_close_pipe, remove prototypes for
4887 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
4889 * posix.c (scm_mknod): split the mode argument into type and perms
4890 arguments, like the extra fields returned by stat.
4892 * fports.c (scm_pipob): set the close, free and print procedures.
4893 (scm_close_pipe): new procedure.
4895 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
4896 define them in boot-9.scm
4898 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4900 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4901 wan't defined. Don't include fd.h.
4903 * Previously fd.h was regenerated whenever configure was run,
4904 forcing a couple of files to be recompiled.
4906 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
4907 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
4908 Check for _fileno as well as _file.
4910 * ioext.c: don't fd.h.
4911 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
4914 * Change the stratigy for getting information about errno
4915 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
4916 generating lists of symbols during the build process, which will
4917 not always work, include comprehensive lists in the distribution.
4918 To help keep the lists up to date, the "check_signals" and
4919 "check_errnos" make targets can be used.
4921 * configure.in: don't check for a command to extract errno codes.
4922 * Makefile.am: update file lists, remove errnos.list and errnos.c
4923 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
4924 check_errnos targets.
4925 (CLEANFILES): remove errnos.c and errnos.list, add
4926 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
4927 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
4928 * errnos.default: deleted.
4929 * cpp_signal.c: new file.
4930 * cpp_errno.c: renamed from errnos_get.c.
4931 * cpp_err_symbols, cpp_sig_symbols: new files.
4932 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
4933 * error.c (scm_init_error): #include cpp_err_symbols instead of
4935 * posix.c (scm_init_posix): don't intern signal symbols. #include
4938 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
4940 * strop.c (scm_i_index): allow the lower bound to be equal to the
4941 length of the string, so a null string doesn't always give an error.
4943 * posix.h: new prototypes.
4944 * posix.c (scm_status_exit_val, scm_status_term_sig,
4945 scm_status_stop_sig): new functions, as in scsh. They break down
4946 process status values as returned by waitpid.
4948 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
4950 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
4951 configure doesn't know about it.
4953 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4955 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
4957 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
4958 which defines C variables with global linkage.
4960 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4962 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
4965 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
4967 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
4968 has time to check why this doesn't work well with continuations.
4970 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
4972 * Fix shell syntax error; some shells won't tolerate
4973 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
4975 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
4977 * posix.c (scm_uname): throw an error if uname fails instead
4980 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
4982 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
4985 * async.c (scm_ints_disabled): definition moved from error.c.
4987 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4989 * acconfig.h: Removed PACKAGE.
4991 * scmconfig.h.in: Regenerated.
4993 * snarf.h: g++ says it's non-portable not to specify the first
4994 argument in a varargs declaration. I introduced the first
4995 argument by using preprocessor conditionals.
4997 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
4999 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5000 (scm_freopen): use RO string macros for filename and modes.
5001 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5003 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5004 (scm_mknod): use RO string macros for path.
5006 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5007 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5009 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5010 use SCM_ROSTRINGP and SCM_ROCHARS.
5012 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5014 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5017 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5018 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5019 support for byte vectors.
5021 * print.c (scm_iprin1): Limit number of vector elements printed
5022 according to pstate->length.
5024 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5026 * backtrace.c (scm_display_error_message): don't segv if message
5029 * error.h: prototype for scm_error_scm.
5031 * error.c (scm_error_scm): new procedure, reimplements scm-error
5032 in C and uses scm_error.
5034 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5036 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5037 pointer to the Scheme variable read-hash-procedures and intern it
5038 in scm_init_read. Modify scm_read_hash_extend and
5039 scm_get_hash_procedure to use the pointer.
5041 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5043 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5044 (SCM_KEYWORD_STYLE): defined.
5046 * read.c (scm_read_opts): add a keywords option. This isn't a
5047 boolean option, in case someone wants to add support for DSSSL
5049 Setup scm_keyword_prefix symbol.
5050 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5052 I've left keyword support disabled by default, since it doesn't
5053 seem to break the module system and it gives R4RS standard behaviour.
5054 It can be reactivated with (read-set! keywords 'prefix).
5056 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5058 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5059 before constructing arbiter.
5061 * eval.c (scm_m_define): Bugfix: Check that the object is a
5062 closure before setting the procedure property!
5064 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5066 * ports.c: Removed `ungetc-char-ready?'.
5068 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5070 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5071 (idea from Mikael: make it a pair so scm_permanent object only
5073 (scm_read_hash_extend): don't call scm_permanent_object.
5074 (ideas from Mikael): if chr is already in the list, replace its
5075 procedure instead of appending it again. If proc is #f, remove
5077 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5079 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5081 * gdbint.c (gdb_read): update scm_lreadr usage.
5083 * load.h: update prototypes.
5085 * load.c (scm_primitive_load, scm_read_and_eval_x,
5086 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5088 * read.h: add prototype for scm_read_hash_extend. Change args for
5091 * read.c (scm_read_hash_procedures): new variable.
5092 (scm_read_hash_extend): new procedure.
5093 (scm_get_hash_procedure): new procedure.
5094 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5095 for extended # processing.
5096 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5097 scm_read_token): remove case_i, sharp arguments. Change callers.
5099 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5101 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5102 (SCM_CASE_INSENSITIVE_P): define.
5104 * read.c: add case-insensitive option to scm_read_opts.
5105 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5106 to determine whether to convert symbol case.
5107 (default_case_i): definition removed.
5108 * read.c (scm_read_token): if case_i, downcase ic before doing
5111 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5113 * configure.in: Added configuration option `guile-debug'.
5114 Configure with --enable-guile-debug if you want a bunch of extra
5115 functions used for debugging when developing Guile.
5117 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5119 * procs.c (make-cclo): New undocumented debugging procedure: Make
5120 compiled closure with internal procedure PROC and length LENGTH.
5121 Only compiled if GUILE_DEBUG is defined.
5123 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5125 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5127 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5129 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5130 with 3 or more args internally to the evaluator.
5132 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5134 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5135 with 3 or more args internally to the evaluator. This is mainly
5136 because we don't want to pass entry and exit points of the
5137 debug support twice, but it also seems to increase the speed of
5138 the evaluator for such calls (e. g. (+ 1 2 3)).
5140 * backtrace.c (scm_display_application): New procedure:
5141 display-application; Set fancy printing parameters individually
5142 for different types of display (backtrace, error, application).
5143 (These should of course be customizable!)
5145 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5146 clear the CHECK-flags.
5148 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5150 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5152 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5154 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5155 from pairs with a GLOC in the car.
5157 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5158 otherwise `symbol-hash' will behave badly.
5159 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5160 we get segmentation fault!
5162 * symbols.c: Added #include "weaks.h". New functions:
5163 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5164 moved to an extraneous library when we split libguile.)
5166 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5168 * filesys.c (scm_stat): stat now takes fport arguments too as
5169 documented in the manual.
5171 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5173 * debug.c (scm_single_step): Bugfix: Call continuation with
5174 scm_call_continuation instead of throwing to it.
5176 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5178 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5179 argument wasn't declared to be optional.
5181 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5183 * stime.c (scm_init_stime): Add feature "current-time".
5185 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5187 * throw.h: prototype for scm_exit_status.
5188 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5189 args to derive an exit status. Allows (quit) to work from a
5191 (scm_exit_status): new function.
5194 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5196 * eval.c (scm_deval): Removed some old code.
5197 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5199 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5202 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5205 * procs.c: Introduce the existent C function scm_thunk_p at the
5206 Scheme level as well.
5208 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5210 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5211 used from C to easily lookup the value of a symbol in the current
5214 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5216 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5217 scm_init_unif in this file. This will also fix a previous problem
5220 * configure.in: Added AM_MAINTAINER_MODE
5222 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5224 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5227 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5229 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5230 source files that are not always included in libguile but should
5231 have their dependencies calculated by automake. This variable is
5232 recognized by automake, no further magic is needed.
5233 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5234 to deal exclusively with *.lo files, as it seems. The *.o files
5235 are built automatically when the corresponding *.lo file gets
5238 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5240 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5243 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5245 * unif.c (scm_array_set_x): minor change to argument error checking.
5247 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5249 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5250 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5251 They should only be included in the library at configure.in's
5253 (libguile_la_LDADD): Include the appropriate .lo files here.
5254 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5255 so we know when to build them (and their .lo bretheren).
5256 * configure.in (LIBLOBJS): New substituted variable. We let
5257 configure decide which .o files to include in LIBOBJS, and then
5258 put the corresponding list of .lo files in LIBLOBJS. The latter
5259 is what we pass to libtool.
5260 * Makefile.in, configure: regenerated.
5262 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5264 * symbols.c (scm_sysintern0): New function. Contains the core of
5265 old scm_sysintern but doesn't take a second value argument.
5266 (scm_sysintern): Now uses scm_sysintern0.
5267 (scm_sysintern_no_module_lookup): Renamed to
5268 scm_sysintern0_no_module_lookup and doesn't take a second value
5269 argument any longer.
5271 * symbols.h (scm_sysintern0: Added declaration.
5273 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5274 scm_sysintern when interning option keys. Otherwise we risk
5275 destroying the values of already interned variables.
5277 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5278 scheme-level boolean (use SCM_NFALSEP).
5280 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5282 (scm_backtrace): New function. (C version of old function from
5283 boot-9.scm) Motivation: Make it possible to display backtraces
5284 without depending on boot-9.scm. (I'm uncertain if this
5285 motivation is good enough...)
5287 * root.h (scm_root_state): Add member the_last_stack_var.
5288 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5290 * root.c (mark_root): Mark scm_the_last_stack_var.
5292 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5295 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5297 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5298 1. mark_lazy_catch didn't mark the smob.
5299 2. Both functions above have standard variants:
5300 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5301 free_lazy_catch --> scm_free0.
5303 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5305 * throw.c (scm_internal_lazy_catch): New function.
5306 (scm_lazy_catch): Rewritten to use it.
5307 (scm_ithrow): Handle the new lazy catch representation.
5308 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5309 that doesn't have a jmpbuf is a lazy catch clause.
5310 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5311 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5312 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5314 (scm_init_throw): Register the new lazy-catch smob type.
5315 * throw.h (scm_internal_lazy_catch): decl for new function.
5317 * throw.c (scm_internal_catch): Doc fixes.
5319 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5320 configure.in. Including this might cause problems if applications
5321 that link against libguile include their own copies of alloca, but
5322 if they're using autoconf, they should be adding libguile to LIBS
5323 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5324 the copy in libguile, and things will be okay. (I think.)
5326 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5328 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5330 strop.h: move prototypes too.
5332 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5334 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5337 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5338 etc. I deleted them from filesys.c long ago, but didn't
5339 notice they were here too (although ineffective since
5340 sys/stat.h wasn't included).
5342 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5344 * eval.c: Don't define alloca in GCC case. gcc will automatically
5345 use __builtin_alloca if appropriate.
5347 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5349 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5350 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5351 that values of automatic variables are preserved. See comments
5352 for safe_setjmp for details.
5354 Change from Thomas Morgan:
5355 * variable.c: Include eq.h.
5356 (var_equal): New function.
5357 (variable_smob): Use var_equal as the discriminator for variables.
5359 * throw.c (s_throw): Remove extraneous declaration.
5361 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5362 * eval.c: Add necessary CPP cruft to support that.
5363 * configure, Makefile.in, scmconfig.h.in: regenerated.
5365 Change from Thomas Morgan:
5366 * procprop.c (scm_procedure_properties): Convert the Scheme
5367 boolean returned by scm_procedure_p into a C boolean before using
5368 it as a condition for SCM_ASSERT.
5369 (scm_procedure_property): Likewise.
5371 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5372 indications of Unixness.
5375 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5377 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5379 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5381 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5382 "unknown # object" error messages.
5384 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5385 (scm_i_index) and declare it static. Add a 'direction' argument
5386 to indicate what way the search should go.
5387 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5389 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5390 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5392 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5394 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5396 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5397 to avoid clash with various scsh forks.
5399 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5401 The following two changes (ramap.c, throw.c) are motivated by the
5402 apparent unportability of forward declarations of static arrays of
5403 the form `static foo bar[];'.
5405 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5406 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5408 * throw.c (scm_throw): Moved above scm_ithrow.
5410 * options.h: Removed the extern declarations of scm_yes_sym and
5411 scm_no_sym since these are static.
5413 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5415 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5417 * Makefile.am: remove AWK=@AWK@.
5418 Add a rule for generating errnos.list.
5419 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5421 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5422 don't extract errnos, just set a variable (avoids the
5423 need to recompile error.c just because configure is run.)
5425 * unif.h: update prototypes.
5426 * unif.c (scm_uniform_array_read,write): change the offset and
5427 length arguments to start and end, for consistency.
5429 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5431 * ioext.h: update prototypes.
5432 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5433 scm_read_line_x, it's a more general procedure using an
5434 interface from scsh. read-line and read-line! are now defined
5436 Note that the new read-line trims the terminator
5437 by default, previously it was appended to the returned string. An
5438 optional argument specifies how to process the terminator (scsh
5439 compatible). For the old behaviour: (read-line port 'concat).
5440 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5441 returns a pair, but is converted to multiple values if the scsh
5444 socket.h: update prototypes.
5445 * socket.c (scm_recvfrom): for consistency with other procedures,
5446 take start and end as separate optional arguments.
5447 (scm_recv, scm_recvfrom): don't allow the second argument
5448 to be a size, only a buffer. Change the scheme names to
5449 recv! and recvfrom!. Don't return the buffer.
5451 * ioext.h, posix.h: move prototypes too.
5452 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5453 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5454 "read.h" and "unif.h".
5455 * ioext.c: include "chars.h"
5457 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5459 * dynl.c: The dynamic linking and module registration functions
5460 are now defined even when dynamic linking is not available for the
5461 host system. Some of their functionality can be done without
5462 dynamic linking; when it's really needed, they throw errors.
5464 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5466 * configure.in: Only define DYNAMIC_LINKING when one of the system
5467 dependent functions is detected.
5468 * dynl.c (scm_dynamic_func): New function to get the address of a
5469 function in a dynamic object.
5470 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5471 produced by scm_dynamic_func as the thing to call.
5473 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5475 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5476 (scm_register_module_xxx, scm_registered_modules,
5477 scm_clear_registered_modules): New functions.
5479 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5481 * symbols.c (scm_sysintern): Renamed to
5482 scm_sysintern_no_module_lookup.
5483 (scm_sysintern): New function to take the place of the old
5484 scm_sysintern. It uses the current toplevel lookup closure to give
5485 the symbol its value. This is a temporary hack to put packages
5486 like gtcltk into their own module.
5487 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5488 us whether `scm_top_level_lookup_closure_var' has been initialized
5490 * eval.c (scm_init_eval): Set it.
5492 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5494 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5495 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5497 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5499 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5500 scm_sys_dup): deleted: FD capability will be added to other
5502 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5503 scm_fd_free, fd_smob, scm_intern_fd.
5504 (scm_open): renamed from scm_sys_open. Return a port instead of
5505 an FD object. Make the mode argument optional.
5506 (scm_sys_create): deleted, it's just a special case of open.
5507 (scm_init_filesys): move interning of constants O_CREAT etc.,
5508 here (were previously using SCM_CONST_LONG macro).
5509 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5511 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5512 include "fports.h" and <stdio.h>
5513 (scm_stat, scm_select): don't support FD objects.
5515 * error.h: adjust scm_syserror_msg prototype.
5516 * error.c (scm_syserror_msg): take an extra argument for errno.
5517 Using the global value didn't always work, since it could be
5518 reset by procedure calls in the message or args arguments.
5520 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5521 I don't understand why the check was there (and what about the
5524 * strop.c (scm_string_copy): allow shared substrings to be copied.
5526 * unif.h: corresponding change to prototypes.
5527 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5528 recognize two new optional arguments: offset and length. Allow
5529 the port argument to be an integer (file descriptor, for scsh).
5530 Include <unistd.h> for "read" prototype.
5532 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5534 * socket.c: don't include filesys.h.
5536 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5538 * Makefile.am: add AWK=@AWK@ (?)
5540 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5542 Add a rule to generate errnos.c from errnos.
5543 * error.c (scm_init_error): include errnos.c.
5544 * errnos_cnvt.awk: new file, converts the list of errno codes to
5546 * errnos_get.c: new file.
5547 * errnos.default: new file, contains errnos to try if they can't
5548 be extracted from errno.h.
5549 * configure.in: if using GCC, try and extract errno codes from
5553 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5555 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5556 * Makefile.am: Made libguile into a libtool library.
5557 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5558 Set libtool_libs to indicate that libguile is a libtool library.
5559 See guile/ChangeLog for details.
5560 * .cvsignore: ignore "*.lo", the libtool library objects.
5562 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5564 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5565 use htons in getservbyport argument.
5567 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5569 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5570 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5573 * objprop.c (scm_object_property): No need to take the CDR of the
5574 value returned by scm_object_properties, since Aug 20 change.
5576 * configure.in: When checking for struct linger, #include
5577 <sys/types.h> as well as <sys/socket.h>. I've never known
5578 <sys/types.h> to cause any portability problems, and Solaris's
5579 <sys/socket.h> needs it.
5580 * configure: Rebuilt.
5582 I think the Sun compiler has chosen a perverse way to interpret
5583 ANSI declarations combined with K&R definitions. We'll
5584 appease it a little bit. But when it invades France, we fight.
5585 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5586 * print.h (scm_iprlist): Here too.
5587 * numbers.c (scm_divbigdig): Change definition to match
5588 declaration in numbers.h.
5589 * unif.c (scm_makflo): Change definition to match declaration in
5592 * init.c (scm_boot_guile): Don't return the value of
5593 scm_boot_guile_1. This function doesn't return a value;
5594 scm_boot_guile_1 doesn't return a value (or return at all).
5596 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5599 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5600 compile. I have a feeling this function is a bad idea anyway ---
5601 one should always test for features, not systems.
5603 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5604 semicolons. Only pure luck kept this from being noticed earlier.
5606 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5608 * socket.c (scm_recvfrom): Added missing semicolon.
5610 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5612 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5613 the buffer and start and end positions for scsh networking
5616 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5618 * configure.in: Revert previous change to this file; the problem
5619 is due to transient automake weirdness.
5620 * configure: Rebuilt.
5622 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5623 PLUGIN/guile.libs. configure generates the latter from the former.
5624 * Makefile.in: Rebuilt.
5626 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5627 need this if we install scripts, like guile-snarf.
5628 * configure: Rebuilt.
5630 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5632 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5634 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5636 * socket.c (scm_addr_vector): fix faulty scm_listify.
5638 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5640 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5641 style block comment is no longer considered an error.
5643 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5645 * PLUGIN/guile.libs.in: New file.
5646 * PLUGIN/guile.libs: Removed from repository.
5647 * configure.in: Create PLUGIN/guile.libs from
5648 PLUGIN/guile.libs.in. This is for including additonal libraries
5649 needed for dynamic linking.
5650 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5651 instead of PLUGIN/guile.libs.
5653 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5655 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5657 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5658 occurrences of the given element from the list, not just the
5659 first. This is how the Emacs Lisp functions behave, how the
5660 analogous Common Lisp functions behave, and (I believe) how the
5661 older Maclisp functions worked. I realize that this change may
5662 break code, but it seemed better to break it before the Guile
5665 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5666 Their prototypes were already present in gc.h, but they weren't
5668 (scm_init_storage): Initialize scm_protects.
5669 * root.c (scm_protects): New element of scm_sys_protects.
5671 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5673 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5675 * libguile.h: Added #include "libguile/net_db.h".
5677 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5678 30 change. That file is only meant for communication between the
5679 configuration process and load.c. If code linked against libguile
5680 wants to get at the paths mentioned in libpath.h, it can call
5681 functions declared in load.h.
5683 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5685 * libguile.h: Removed #include "libguile/fdsocket.h"
5687 * net_db.c: Added #include <sys/socket.h>.
5689 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5691 * filesys.c (scm_input_waiting_p): use select in preference to
5692 FIONREAD, since the latter doesn't detect EOF.
5693 Throw error if neither select nor FIONREAD available.
5695 * socket.c (scm_connect): take a port, not a fd object.
5696 (scm_fill_sockaddr): throw an error if fam is not recognised.
5697 (scm_bind): use scm_fill_sockaddr.
5698 (scm_listen): take a port, not a fd object.
5699 (scm_accept): take and return a port. return #f in the car if
5700 address can't be got
5701 (scm_sock_fd_to_port): new procedure.
5702 (scm_socket): use scm_sock_fd_to_port.
5703 (scm_addr_vector): throw error if unrecognised address type.
5704 take an extra argument with the calling procedure name.
5705 (scm_getsockname): take a port. return #f if address can't be got.
5706 (scm_getpeername): take a port. return #f if address can't be got.
5707 (scm_recvfrom): take a port. return #f for address component if can't
5709 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5710 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5712 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5714 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5715 use separate data pointers, to allow them to be designed
5716 independently and reused.
5717 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5718 Renamed from catch_body, catch_handler, and uncaught_throw; made
5720 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5722 (scm_catch): Use the above.
5723 (scm_throw): Don't bother printing a message for an uncaught
5724 throw; we establish a default handler in init.
5725 * throw.h (scm_internal_catch): Prototype updated.
5726 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5728 (struct scm_body_thunk_data): New structure, used as data
5729 argument to scm_body_thunk.
5730 * init.c (struct main_func_closure): New structure, packaging up
5731 the data to pass to the user's main function.
5732 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5733 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5734 scm_internal_catch to establish a catch-all handler, using
5735 scm_handle_by_message. This replaces the special-case code in
5737 (invoke_main_func): Body function for scm_internal_catch; invoke
5738 the user's main function, using the main_func_closure pointer to
5739 decide what to pass it.
5740 * root.c (struct cwdr_body_data): Remove handler_proc member.
5741 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5742 (cwdr_handler): Removed.
5744 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5746 * socket.h (SCM_P): update bind prototype.
5747 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5748 include "feature.h".
5749 (scm_socket): return a port, not a file descriptor object.
5750 include "fports.h" and <unistd.h>
5751 (scm_bind): take a port, not a file descriptor object.
5752 take an extra argument for address args.
5754 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5755 INADDR_NONE, INADDR_LOOPBACK.
5757 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5759 * init.c: include net_db.h and not fdsocket.h.
5760 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5762 * Makefile.am: corresponding changes.
5763 * socket.h: renamed from fdsocket.h, fix names.
5764 * net_db.h: renamed from socket.h, fix names.
5765 * socket.c: renamed from fdsocket.c.
5766 remove _sys from procedure names.
5767 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
5768 add "socket" to features list.
5769 * net_db.c: renamed from socket.c.
5770 remove _sys from procedure names.
5771 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
5772 add "net-db" to features list.
5773 include "net_db.h". don't include <sys/socket.h> or
5776 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5778 * tags.h (scm_tags): Removed comma at end of last enumerator.
5780 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
5782 Don't use GCC extensions to allocate space for debugging frames.
5783 (Here he goes again! Why do we put up with this?!)
5784 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
5785 an scm_debug_info structure, not an in-line array of them. Add
5786 'info' member, to say how many vect elements we've used, for eval
5788 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
5789 a new variable debug_info_end to mark the end of vect, instead of
5790 the address of the 'info' pointer itself.
5791 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
5792 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
5793 (SCM_APPLY): Explicitly allocate space for debug.vect.
5794 * debug.c (scm_m_start_stack): Same, for vframe.vect.
5795 * stacks.c: Adjusted for new debug frame structure.
5796 (RELOC_INFO, RELOC_FRAME): New macros.
5797 (stack_depth, read_frames): Use them, and new scm_debug_frame
5798 element 'info', instead of magically knowing that eval frames have
5799 an info pointer sitting after vect.
5800 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
5802 (scm_init_stacks): Formatting tweaks.
5804 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
5806 Give GCC more control flow information, so it can be sure that
5807 variables aren't used uninitialized.
5808 * error.h (scm_error, scm_syserror, scm_syserror_msg,
5809 scm_sysmissing, scm_num_overflow, scm_out_of_range,
5810 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
5811 scm_misc_error): Tell GCC that these functions never return.
5812 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
5813 out the field type, call abort if SCM_ASSERT returns, to placate
5815 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
5816 scm_wta ever returns. We can't handle this case anyway, and this
5817 gives the optimizer more information.
5818 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
5819 scm_wta ever returns.
5821 In some cases, the code is fine, but GCC isn't smart enough to
5822 figure that out; this usually happens when one variable is only
5823 initialized and used when a particular condition holds true, and
5824 we know that condition will never change within a given invocation
5825 of the function. In this case, we simply initialize the variables
5826 to placate the compiler, hopefully to a value which will cause a
5827 crash if it is ever actually used.
5828 * print.c (scm_iprin1): Initialize mw_pos.
5829 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
5830 * throw.c (scm_ithrow): Initialize dynpair.
5831 * unif.c (scm_uniform_vector_ref): Initialize cra.
5832 * struct.c (init_struct): Initialize prot.
5833 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
5835 * strports.c (scm_eval_0str): Don't return uninitialized garbage
5836 if EXPR contains no expressions.
5838 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5840 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
5841 cause an infinite loop (???). So much for the algebraic
5842 equivalency of variable-sized arrays and alloca...
5844 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
5846 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
5847 a SCM boolean, not a C boolean.
5849 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
5851 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
5852 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
5853 rules for raising scm_mtrigger. Previously, unfortunate but not
5854 unlikely circumstances could result in almost constant invokation
5855 of the gc. Now, this situations should be less likely, but they
5856 are not prevented completely.
5858 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
5860 * numbers.c (scm_fuck): Procedure removed; looks like old test
5862 * numbers.h: Prototype removed.
5864 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
5866 * debug.h (scm_debug_frame): Change `vect' member from an in-line
5867 array to a pointer, to match my Nov 21 change in eval.c.
5869 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5871 * libguile.h: Added #include "libguile/backtrace.h", #include
5872 "libguile/stacks.h".
5874 * strings.c (scm_string scm_make_string scm_string_ref
5875 scm_string_set_x scm_string_equal_p scm_string_append):
5876 Bugfix according to scm patch from Aubrey Jaffer:
5877 Corrected long-standing
5878 (not (eqv? (integer->char 128)
5879 (string-ref (make-string 1 (integer->char 128)) 0)))
5880 bug found by John Kozak <jk@noontide.demon.co.uk>.
5882 * strports.c, strports.h: Make scm_eval_0str return the value of
5883 the last expression evaluated (previously, it returned void).
5885 * strports.c, strports.h: New function: scm_read_0str. Does what
5888 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5890 * simpos.c (scm_getenv): return #f if string can't be found in the
5891 environment instead of throwing an exception, for compatibility
5892 with numerous other systems.
5894 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
5896 * Makefile.am (.c.x): Use guile-snarf.
5897 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
5899 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
5901 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5903 * backtrace.c (scm_display_error_message): Made non-static, and
5904 renamed from display_error_message.
5905 * backtrace.h (scm_display_error_message): Added extern decl.
5906 * throw.c (uncaught_throw): Use it to display the error message.
5908 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
5910 * inet_aton.c: Use #if 0, not #ifdef 0.
5912 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
5914 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
5915 to convert the returned value.
5916 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
5917 the offset argument.
5919 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
5921 Add new interface to catch/throw, usable from C as well as
5923 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
5924 (scm_internal_catch): New function, replaces...
5925 (scm_catch_apply): Deleted.
5926 * throw.c (scm_catch_apply): Deleted; replaced with a more general
5927 mechanism which is a bit more code, but can be used nicely from C
5928 and implement the Scheme semantics as well.
5929 (scm_internal_catch): This is the replacement; it's named after
5930 the analogous function in Emacs.
5931 (scm_catch): Reimplemented in terms of the above.
5932 (struct catch_body_data, catch_body, catch_handler): New
5933 functions, used by scm_catch.
5934 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
5935 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
5936 support for new cwdr.
5938 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
5941 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
5943 * acconfig.h: Added DYNAMIC_LINKING symbol.
5944 * configure.in: Add option and checks for dynamic linking.
5945 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
5946 dynl.h: New files for dynamic linking support.
5947 * Makefile.am (libguile_a_SOURCES):
5949 (modinclude_HEADERS): Added "dynl.h".
5950 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
5952 * init.c (scm_boot_guile_1): Call
5953 scm_init_dynamic_linking to initialize dynamic linking support.
5955 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
5957 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
5958 (as we Schemers say). It needs to be global, so that I can tweak
5959 it for the proper operation of unexec.
5960 (scm_boot_guile_1_live): New variable, see above.
5962 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
5964 * guile-snarf.sh: Removed.
5965 * PLUGIN/guile.libs: Added dependency for -lm.
5966 * acinclude.m4: Renamed from aclocal.m4.
5967 * PLUGIN/greet: Removed.
5968 * Makefile.am, aclocal.m4: New files.
5969 * configure.in: Updated for Automake.
5971 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
5973 * eval.c (scm_definedp): Use top_level_lookup_closure_var
5974 and not top_level_lookup_thunk_var.
5976 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
5978 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
5980 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
5982 * eval.c (scm_definedp): Incompatibly changed to be a builtin
5983 Scheme function, instead of syntax. Single argument is now a
5986 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5988 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
5989 scm_ra_divide): Properly terminate statements passed as arguments
5990 to IVDEP macros. (Thanks to Bernard Urban.)
5992 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
5993 with non-constant sizes. (Thanks to Bernard Urban.)
5995 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
5997 It's an "eval closure", not an "eval thunk." A thunk is a
5998 function of no arguments.
5999 * root.h (struct scm_root_state): Renamed
6000 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6001 (scm_top_level_lookup_closure_var): Renamed from
6002 scm_top_level_lookup_thunk_var.
6003 * root.c (mark_root): Uses changed.
6004 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6005 * init.c (scm_start_stack): Uses changed.
6006 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6007 Change scheme-visible name to *top-level-lookup-closure* from
6008 *top-level-lookup-thunk*.
6010 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6012 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6013 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6015 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6017 * gc.c (struct scm_heap_seg_data): Doc fixes.
6019 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6020 sweeping. Then, prepend each segment's free cells to its
6021 freelist, rather than wiping out the old value. (Thanks to Marius
6024 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6025 scm_check_freelist, scm_debug_newcell): New functions and
6026 variables, for debugging freelist problems.
6027 * pairs.h (SCM_NEWCELL): New debugging version added.
6028 * gc.h (scm_debug_newcell): Added extern declaration, used by
6029 debugging version of SCM_NEWCELL.
6031 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6033 On some systems <libc.h> conflicts with <unistd.h>, and should not
6034 be #included at all.
6035 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6036 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6037 * configure.in: Call it.
6038 * posix.c, filesys.c: Use its results to decide whether or not to
6040 * configure, scmconfig.h.in: Rebuilt with autoconf and
6043 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6045 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6046 pointer to the stdio stream before calling scm_setbuf0, so the
6047 latter will be able to retrieve it. I'm surprised this didn't
6048 segfault earlier. (Thanks to Christopher Lee.)
6050 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6052 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6055 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6057 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6058 number of stack narrowing specifier pairs. The first specifier in
6059 a pair controls inner border, the second the outer border. A
6060 number means cut that number of frames, a procedure object means
6061 cut until that object is found in operator position in a frame.
6063 * root.c (cwdr): Bugfix.
6065 * read.c: Recording of positions disabled by default.
6067 * procs.c (scm_closure_p): New function.
6069 * posix.c (scm_tmpnam): New function.
6071 * load.c: Added #include "throw.h".
6072 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6075 * load.c, load.h (scm_read_and_eval_x): New function.
6077 * eval.c: Renamed debug option "deval" to "debug".
6079 (scm_eval_x): `eval!' is no longer accessible from the scheme
6080 level. Motivation: We can't allow operations which introduce
6081 glocs into the scheme level. Guile's type system can't handle
6082 these as data. Use `eval' or `read-and-eval!' as replacement.
6084 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6085 SCM_CONSP since this is a macro!; Set vframe.prev to
6086 scm_last_debug_frame instead of 0. In this way we can look
6087 "above" the virtual start stack frame if we wish.
6088 (scm_debug_hang): New function: Useful for debugging Guile in
6089 certain tricky situations. Will probably be removed later...
6091 * debug.h: Changed semantics of debug option "backtrace". This
6092 option now only indicates whether we want automatic backtrace at
6095 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6097 * ports.c: #include "filesys.h"
6098 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6100 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6101 Motivation: This is system specific code which is related to file
6102 I/O. It also may use select. Added code by Gary Houston to
6103 detect presence of character in stdio buffers.
6105 * libguile.h: #include "libguile/libpath.h"
6107 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6108 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6109 SCM_SITE_DIR; Install libpath.h among the other include files.
6111 * load.c, load.h (scm_sys_package_data_dir): New function.
6113 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6115 * stacks.h: Bugfix: Don't use tail-array length field as stack
6116 length field! This screwed GC.
6118 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6120 * _scm.h: Added #ifndef around definition of macros min and max.
6122 * __scm.h: Added hooks for threads to plugin to in ints protection
6123 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6124 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6125 the main code in these macros duplicated and spread over multiple
6126 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6127 SCM_THREAD_SWITCHING_CODE.
6129 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6131 * snarf.h: New file.
6132 * guile-snarf.sh: New file.
6133 * Makefile.in (inner_h_files): Added snarf.h
6134 (ancillary, install, uninstall, distclean): Added actions for
6136 (.c.x): Use guile-snarf.
6137 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6138 (gen_c_files): Note that these depend on guile-snarf.
6139 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6140 now in "snarf.h". Added #include "snarf.h" to get them.
6141 * libguile.h: Added #include "snarf.h".
6142 (Patches applied and tweaked by Jim Blandy.)
6144 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6146 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6147 standards suggest against providing prototypes for system
6148 functions. Thanks to Greg Troxel.
6150 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6152 * strports.c (scm_eval_0str): New function.
6153 #include "read.h", to get prototype for scm_read.
6154 * Makefile.in (strports.o): Update dependencies.
6155 * strports.h: New prototype.
6157 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6158 scheme name from "int?" to "integer?". It seems to do the job.
6159 * numbers.h: Rename prototype too.
6160 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6163 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6164 scm_num_eq_p): Rename these according to R4RS conventions: call
6165 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6166 to making libguile R4RS compliant without ice-9...
6168 * load.c (scm_sys_search_load_path): Search for files under all
6169 extensions listed in the %load-extensions variable. If FILENAME
6170 is absolute, return it unchanged, without searching the load path.
6171 (scm_loc_load_extensions): New variable, pointing to
6172 %load-extensions' value cell.
6173 (scm_init_load): Initialize it, and the value it points to.
6174 (scm_primitive_load_path): Improve error reporting.
6176 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6177 of new Scheme variable %load-hook.
6178 (scm_primitive_load): Apply %load-hook to filename.
6180 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6182 * configure.in: add tests for figuring out whether buffered data
6183 is available in a FILE structure, which is needed by char-ready.
6185 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6188 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6189 exceptions using misc_error instead of syserror. It seems a bit
6190 odd to throw an exception if a string can't be found in the
6191 environment, but it's consistent with open-file, stat etc.
6192 (simpos.h): remove sys_ from getenv.
6194 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6195 occurs, throw an error instead of returning errno. Return value
6197 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6199 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6201 * filesys.c (scm_stat2scm): derive file type and permissions from
6202 the stat mode and append them to the returned vector.
6203 There isn't much overhead in doing this and it avoids the need to
6204 work with S_IRUSR et al. in Scheme.
6205 Define symbols scm_sym_regular etc.
6206 (scm_init_filesys): don't intern S_IRUSR etc.
6208 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6209 and s_primitive_load_path.
6211 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6213 * error.h: don't declare error symbols. prototype for scm_misc_error.
6215 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6218 * error.c: use SCM_SYMBOL to set up error keys.
6219 scm_misc_error: new procedure.
6221 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6223 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6224 between `#!' and `!#' is ignored.
6225 (skip_scsh_block_comment): New function.
6227 * feature.c (scm_set_program_arguments): New argument, FIRST.
6228 * feature.h: Update prototype.
6229 * init.c (scm_boot_guile_1): Pass new argument to
6230 scm_set_program_arguments.
6232 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6234 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6235 (scm_boot_guile): Call scm_set_program_arguments here, later than
6236 the old initialization.
6238 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6239 initialization procedure.
6240 - Delete in, out, err arguments; there are other perfectly good
6241 ways to override these when desired.
6242 - Delete result argument; this function shouldn't ever return.
6243 - Rename init_func argument to main_func, for less confusion.
6244 - Delete boot_cmd argument; main_func is more general.
6245 -Add 'closure' argument, to help people pass data to main_func
6246 without resorting to global variables.
6247 - Abort if reentered; don't bother returning an error code.
6248 - Call scm_init_standard_ports to set up the default/current
6249 standard ports; no need to pass them to scm_start_stack.
6250 - Remove code to evaluate the boot_cmd, and start the repl; let
6251 the user do something like that in main_func if they want.
6252 - Remove code to package up a return value; main_func can do any
6254 - Call exit (0), instead of returning.
6255 (scm_start_stack): Don't initialize the I/O ports here; that's
6256 weird. Delete in, out, err arguments. Move guts to
6257 scm_init_standard_ports, scm_stdio_to_port.
6258 (scm_init_standard_ports): New function, to set up current and
6259 default standard ports.
6260 (scm_start_stack, scm_restart_stack): Make these static.
6261 * init.h (scm_boot_guile): Adjust declaration.
6262 (scm_start_stack, scm_restart_stack): Remove externally
6263 visible declarations for these.
6264 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6266 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6267 written out several times in scm_start_stack.
6268 * fports.h: New declaration for the above.
6270 * feature.c (scm_set_program_arguments): New function.
6271 * feature.h: New declaration for the above.
6273 * ports.c: Formatting tweak.
6275 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6277 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6278 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6279 for obtaining the address of a car or cdr field. Motivation:
6280 &SCM_CXR make assumptions about the internal structure of the
6283 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6284 Motivation: see SCM_CXRLOC.
6286 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6287 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6288 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6289 Motivation: Safer use. Some other macros are defined in terms of
6290 these operations. If these are defined using the SCM_SETCXR
6291 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6292 to inefficiency and an <e1> with side-effects could potentially
6293 break. Also, these particular operations are heavily utilized in
6294 the garbage collector. In unoptimized code there will be a
6297 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6298 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6299 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6300 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6301 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6302 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6303 vports.c: Cleaned up use of pairs: Don't make any special
6304 assumptions about the internal structure of selectors and
6305 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6306 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6307 (Among other things, this change makes it easier to build Guile
6308 with certain compilers which have problems with casted lvalues.)
6310 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6312 * stacks.c: Improve selection of relevant stack frames when making
6313 a stack object. Introduce one level of indirection in the stack
6314 object to make it possible to "narrow" to a certain region of the
6315 stack. This facilitates making use of more clever algorithms (not
6316 implemented) for selecting relevant frames and gives a cleaner
6317 design since selection of frames can be done independently of
6318 extraction of frames from the real stack.
6319 (scm_stack_id): Also take #t as argument which means look at
6322 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6323 Turn n_tail into an integer directly representing current number
6324 of frames in stack. Add field tail.
6326 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6328 * debug.c (scm_make_memoized): Made it available at scheme level.
6329 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6330 SCM_NIMP before applying heavier predicates in argument checking.
6331 (scm_local_eval): Also take memoized object as argument.
6333 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6334 aren't created with zero length, but should such a strange
6335 creature suddenly turn up...
6337 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6339 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6340 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6342 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6344 * variable.c (scm_make_variable): Make the name hint optional, as
6346 (anonymous_variable_sym): Renamed from variable_sym. All uses
6349 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6350 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6351 of scm_primitive_load_path was also changed to
6352 "primitive-load-path", from "%try-load-path". Callers changed.
6353 We'd like to respect the convention that a function named
6354 "try-mumble" should behave just like the function called "mumble",
6355 but return #f instead of signalling some error.
6356 * load.h: Rename prototypes.
6358 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6360 * print.c (make_print_state, grow_print_state), print.h: Modified
6361 the print state representation: Don't use a tail array for
6362 recording of circular references. Resizing of the print state
6363 structure invalidates the print state pointer. To avoid passing
6364 around an indirect print state reference to all printing
6365 functions, we instead let the print state reference a resizable
6368 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6370 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6371 Don't crash when passed an improper list terminated by a
6372 non-immediate value.
6374 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6376 Allocate data for structures on an eight-byte boundary, as
6377 required by the tagging system.
6378 * struct.c (alloc_struct): New function.
6379 (scm_make_struct, scm_make_vtable_vtable): Call it.
6380 * struct.h (scm_struct_n_extra_words): Bump to 3.
6381 (scm_struct_i_ptr): New "field".
6382 * gc.c (scm_gc_sweep): When we need to free the data, use the
6383 information stored by alloc_struct to find the beginning of the
6384 block allocated to the structure, so we can free it.
6386 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6388 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6391 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6392 (scm_debug_info): New member: id.
6394 * stacks.c: Stacks are now represented as structs; Stacks have an
6395 id given to them by `start-stack'.
6396 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6398 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6399 Changed stack representation.
6401 * debug.c (scm_procedure_name): Try procedure property `name' for
6402 compiled closures aswell.
6404 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6406 * eval.c: scm_i_name moved to gsubr.c
6407 (scm_m_define): Record names of all kinds of procedure
6408 objects. (Earlier, only closures were recorded.)
6410 * procprop.h: Added declaration of scm_i_name.
6412 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6413 (scm_make_gsubr): Record names of compiled closures.
6415 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6417 * debug.c, debug.h: Removed obsolete code.
6419 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6420 stacks.c: Renamed regs --> scm_contregs.
6422 * print.c (scm_free_print_state): Cleanup print state before
6423 returning it to pool. It is better to do it here than in
6424 scm_prin1 since scm_prin1 is called often.
6426 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6427 s_set_source_property_x): Check that first argument is a pair or a
6430 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6431 scm_i_line, scm_i_column and scm_i_breakpoint global.
6433 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6434 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6437 * debug.h: Added debug object smob declaration and macro
6440 * configure.in: Build with backtrace.o and stacks.o if debug
6443 * Makefile.in: Added entries for new files: backtrace.c,
6444 backtrace.h, stacks.c and stacks.h.
6446 * symbols.c (scm_sym2ovcell): Fixed documentation.
6448 * _scm.h (min, max): Added.
6450 * async.c: Moved `min' macro to _scm.h.
6452 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6453 SCM_BACKTRACE_INDENT.
6455 * eval.c: Added new debug options `maxdepth' and `indent'.
6457 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6459 * print.h: Added selector SCM_PRINT_STATE.
6461 * print.c: New functions: scm_make_print_state,
6462 scm_free_print_state.
6464 * print.h: Added declarations for scm_make_print_state,
6465 scm_free_print_state.
6467 * debug.c (scm_m_start_stack): New acro.
6469 * debug.h: Small cleanup.
6471 * init.c (scm_boot_guile_1): Moved scm_init_debug below

6494 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
6495 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
6496 declare functions with prototypes. (Patch thanks to Marius
6499 More prototype-related changes from Marius Vollmer:
6500 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6501 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6502 * ports.h (ptobfuns): Added prototypes. This means some casting in
6504 * fports.c: Added casts for initializations, since the functions
6505 are defined to take FILE * as their stream argument, not SCM.
6506 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6507 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6508 to `char *str_data' to conform to prototype.
6510 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6512 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6514 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6516 * stime.c, stime.h: use SCM_P method.
6518 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6520 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6521 be given at least two arguments. Insist that lst's last element
6522 be a list, but don't make any requirements of its predecessors.
6524 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6526 * eval.c (scm_nconc2last): Revert last change; there seems to be
6527 other stuff going on here.
6529 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6531 * eval.c (scm_nconc2last): Make sure that each element of lst
6532 (which is a list of argument lists, except for the tail) is a
6533 proper list, i.e., finite and terminated by '().
6535 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6537 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6540 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6541 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6544 * vectors.c (scm_make_vector): Fill vectors with the undefined
6545 value, to help make Guile Scheme code more portable to other
6548 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6549 * symbols.h, tags.h: Doc fixes.
6551 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6553 * async.c (scm_take_signal): Doc fixes.
6555 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6557 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6558 want to subtract it from the modulus; we just want to leave it
6561 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6563 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6566 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6568 * throw.c (scm_catch_apply): Finished implementation of
6571 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6573 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6575 (scm_init_filesys): set "i/o-extensions" feature.
6578 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6580 * Makefile.in (root.o): Correct dependencies.
6582 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6584 * Makefile.in: Added dependency entry for root.o.
6586 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6587 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6589 * init.c (scm_start_stack): Set initial root continuation number
6592 * procs.c: New function: scm_thunk_p.
6594 * procs.h: Added declarations of scm_thunk_p.
6596 * root.c: Renamed `call-with-new-root' -->
6597 `call-with-dynamic-root'.
6598 (cwdr): Removed allocation of new root state. This should be done
6599 separately by use of scm_make_root.
6600 (scm_apply_with_dynamic_root): New function: Does what it
6601 sounds like. Needed when spawning threads.
6603 * root.h: Added member last_debug_frame to root state.
6604 Added #include "libguile/debug.h"
6606 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6607 arguments. The motivation is that code in root.c needs catch
6608 functionality, and we want to avoid code duplication.
6609 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6610 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6611 handlers that run without popping the stack into the dynwind
6614 * throw.h: Added prototypes for scm_catch_apply and
6617 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6619 * root.h (scm_root, scm_set_root): Decouple thread support details
6620 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6621 SCM_SET_THREAD_LOCAL_DATA.
6623 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6624 and tortoise scanning loop.
6626 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6628 * Makefile.in: Rebuild dependencies.
6630 * libguile.h: #include "libguile/print.h" before "smob.h", since
6631 the latter uses the print_state structure.
6633 * throw.c (scm_ithrow): Use the correct variable when checking to
6634 see if a given element of scm_dynwinds is a valid catch.
6636 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6637 structure, abort; don't just silently ignore the garbage.
6639 * _scm.h: #include "print.h" here, since it seems to be used just
6641 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6642 strports.c, unif.h: Don't #include "print.h".
6644 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6646 * feature.h (scm_loc_features): Removed external declaration.
6647 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6649 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6651 * feature.c (scm_init_feature): Added threads feature (needs to be
6652 initialized here, since features doesn't exist when
6653 scm_init_threads is called).
6655 * libguile.h: Added #include "libguile/../threads/threads.h".
6656 (This is a kludge to get thread support working. This should be
6659 * configure.in, acconfig.h: Added flags for thread support.
6661 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6664 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6665 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6668 * _scm.h: Added conditional #include "threads.h"
6670 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6671 SCM_THREADS_SWITCHING_CODE.
6673 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6674 allocate the basic dynamic root object.
6675 (scm_boot_guile): Added call to scm_init_root.
6677 * root.c, root.h: Added root smob.
6678 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6679 functions: Implements dynamic roots mostly according to spec in
6680 SCM manual. Main difference is that the second argument is a
6681 throw handler rather than an error "thunk".
6683 * root.h: Added declaration of scm_init_root.
6685 * root.c: Added #include "genio.h", #include "smob.h", #include
6686 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6688 (scm_init_root): Added #include "root.x".
6690 * throw.c: Added #include "stackchk.h"
6691 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6692 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6693 can be used in scm_call_with_new_root; Added reenabling of stack
6694 checking when catching a throw.
6696 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6698 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6700 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6701 element is not found, as per R4RS.
6703 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6705 * list.c: Doc fixes throughout.
6707 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6709 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6710 declare the char * to be const. Avoids a warning in rgx.c.
6712 * ports.h: spelling fix.
6714 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6717 * load.c (scm_sys_try_load_path): throw an error if file not found
6718 (like it says it in NEWS).
6720 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6722 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6723 PROPS slot to '(), not #f; it's an empty alist.
6725 * throw.h, throw.c: Use SCM_P instead of #if hair.
6727 Remove special support for uncaught throws; see throw.c for
6729 * throw.c (uncaught_throw): New function.
6730 (scm_ithrow): Call uncaught_throw if we don't find a throw
6731 target; don't mess with scm_bad_throw_vcell.
6732 (scm_bad_throw_vcell): Variable deleted.
6733 (scm_init_throw): Don't initialize it.
6735 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6738 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6740 * numbers.c (scm_istr2int): If the number is short (as most
6741 numbers are), just call scm_small_istr2int to deal with it.
6742 (scm_small_istr2int): New function, created by un-#ifdefing the
6743 non-bignum version of scm_istr2int and renaming it.
6745 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6747 * load.c (scm_sys_try_load): don't check whether value returned
6748 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6749 Change the Scheme name from %try-load to primitive-load.
6751 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6752 Can avoid passing a message, allowing it to be derived in the
6753 error handler (e.g., if we want to throw to the key both from
6756 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6758 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6759 references now have a new appearance which is more compact and
6760 also gives a clue about what the target of the reference is.
6761 By setting parameters in the print state, more fancy printing can
6762 be achieved. This is used by the (not yet commited) backtrace
6765 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
6767 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
6770 * print.c: Added #include "struct.h". Removed function
6773 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
6774 scm_iprin1. Removed prototype for scm_prlist.
6776 * arbiters.c (prinarb),
6777 async.c (print_async),
6778 debug.c (prindebugobj, prinmemoized),
6779 eval.c (prinprom, prinmacro),
6780 filesys.c (scm_fd_print, scm_dir_print),
6782 mallocs.c (prinmalloc),
6783 numbers.c, numbers.h (scm_floprint, scm_bigprint),
6784 smob.h (scm_smobfuns),
6785 srcprop.c (prinsrcprops),
6787 unif.c, unif.h (scm_raprin1, rapr1),
6788 variable.c (prin_var): Changed argument `int writing' to
6789 `scm_print_state *pstate'.
6791 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
6792 that it will be called before scm_init_print.
6794 * print.c (scm_prin1): Print states are now allocated when calling
6795 scm_prin1 and then passed around to all printing functions as an
6796 argument. A cache `print_state_pool' enables reuse of print
6798 (scm_make_print_state): New function.
6799 (scm_iprin1): Adaption to print states.
6800 (scm_iprlist): An initial "hare and tortoise" scan brings down
6801 time complexity to O (depth * N). (Better time complexity will be
6802 achieved when the printing code is completely rewritten.)
6804 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6806 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
6807 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
6808 it gets done whether or not the cache variable has a value.
6810 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6812 Distinguish #f and ().
6813 * __scm.h: #undef SICP.
6814 * pairs.h (SCM_EOL): Delete this definition, equating it with
6816 * tags.h (SCM_EOL): Give it a new definition here; I think I found
6817 the value it used to have. Doc fixes, too.
6819 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
6821 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
6822 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
6823 Lord's implementation of structs, allowing for tail arrays as
6824 described in the manual. Also fixed some bugs. (Both the interface
6825 and the implementation should be improved.)
6827 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
6829 * print.c, print.h: Closures now print like #<procedure foo (x)>.
6830 People who whish to see the source can do `(print-enable 'source)'.
6831 Removed #ifdef DEBUG_EXTENSIONS.
6833 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6835 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
6836 integer (assuming for now accepting an integer is a good thing).
6838 * error.c, fports.c: replace use of %S in lgh_error args with %s.
6839 %S will be used instead for write'ing arguments.
6841 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
6842 asserts. fix a few other asserts.
6843 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
6844 scm_uniform_vector_ref, scm_array_set_x,
6845 scm_dimensions_to_unform_array): change args in
6846 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
6847 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
6848 scm_substring_fill_x): likewise.
6849 gsubr.c (scm_gsubr_apply): likewise.
6850 eval.c (SCM_APPLY): likewise.
6852 * eval.c (4 places): replace scm_everr with lgh_error or
6855 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
6856 scm_memory_error): new procedures.
6857 scm_everr: deleted. can use scm_wta, dropping first two args.
6858 scm_error: convert NULL subr to SCM_BOOL_F.
6860 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
6863 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
6866 * error.c, error.h: new error keys: scm_arg_type_key,
6867 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
6869 scm_wta: reimplement using lgh_error instead of scm_everr.
6871 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
6873 * gdbint.c: scm_lread now has one more argument.
6875 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
6876 scm_port_\1; Added mutator scm_set_port_filename_x (used when
6877 loading source from non-file ports, which, e. g., happens when
6878 using the Emacs interface).
6880 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
6883 * read.c: Added code for recording of positions of source code
6884 expressions; New functions: recsexpr, scm_lreadrecparen;
6885 _scm_make_srcprops --> scm_make_srcprops
6886 (scm_flush_ws): Removed updating of positions counters. This work
6887 is already done by scm_gen_getc
6889 * read.h: Added prototype for scm_lreadrecparen
6891 * print.c: Added #include "alist.h"
6893 * eval.c: Added #include "hash.h"
6895 * eq.c: Added #include "ramap.h"
6897 * options.c: Documentation fixes.

6900 (scm_init_srcprop): Adjusted size of initial source-whash. Name
6901 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
6902 --> scm_make_srcprops
6904 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
6905 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
6906 function calls in the definition of the whash access macros.
6908 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
6910 * init.c (scm_boot_guile): Add level of indirection to
6911 scm_boot_guile_1() to ensure that stack base pointer is properly
6912 initialized. There was no guarantee that variable i was the
6913 highest/lowest variable on stack (i.e. the call frame of
6914 scm_boot_guile was not completely protected from gc).
6916 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
6918 * ports.h (scm_port_table): put back file_name, it will be used to
6919 support debugging. Undo related changes in fports.c, ioext.c,
6922 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6924 * ports.h (scm_port_table): remove file_name member for now, it seems
6926 * fports.c (scm_open_file): don't set file_name in PTAB.
6927 (prinfport): don't use file_name in PTAB.
6928 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
6929 * ports.c (scm_add_to_port_table): don't intialize file_name.
6930 (scm_port_file_name): remove for now.
6931 * gc.c (scm_gc_mark): don't mark PTAB file_name.
6933 * fports.h (scm_mkfile): prototype deleted.
6934 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
6936 * debug.c, unif.c: use scm_out_of_range instead of
6937 wta for range errors (ASSERT still needs work).
6939 * error.c, error.h (scm_out_of_range): new procedure.
6941 * error.c, error.h (scm_out_of_range_key): new key.
6943 * posix.c (scm_sync): #else was missing.
6945 * error.c, error.h: append _key to names scm_num_overflow and
6948 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
6949 of consing an empty list.
6950 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
6951 of macros, saves code and string space.
6952 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
6953 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
6954 lower case. Rename scm_syserror_m to scm_syserror_msg.
6955 error.h: prototypes for new procedures.
6957 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
6959 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
6961 * error.c, error.h: setup scm_num_overflow key.
6963 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
6964 Remove definition of SCM_OVSCM_FLOW.
6966 * fports.c (scm_open_file): use SCM_SYSERROR_M.
6968 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
6969 explicit message and args.
6971 * error.c, error.h, __scm.h: change system_error_sym to
6974 * error.c (system_error_sym): remove leading %% from the Scheme name
6977 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
6979 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6981 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
6982 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
6983 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
6984 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
6985 renamed. (These were introduced by unsupervised name
6988 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6990 * print.c: Added code for detection of circular references during
6991 printing. (init_ref_stack, grow_ref_stack): New functions. Added
6992 a hook for printing of closures (accessible via print options).
6993 This leads to a split of calls to scm_iprin1 into two classes:
6994 elementary print operations (e. g. the code which prints a smob)
6995 still use scm_iprin1 while top level calls (like scm_display) use
6996 scm_prin1. scm_prin1 begins by clearing the data structure used
6997 to record reference information.
6999 * print.h: Added declarations of scm_prin1 and scm_prlist.
7001 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7003 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7005 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7007 * error.c (err_head): scm_iprin1 --> scm_prin1
7009 * debug.c: Adjusted header comment.
7013 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7015 * strerror.c: Doc fix.
7017 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7019 * gdbint.c (gdb_read): Now possible to run during GC.
7020 (unmark_port, remark_port): New functions.
7022 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7024 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7025 of allocating a new string object. Also, increase size by
7026 the factor 2 instead of 1.5.
7028 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7030 * __scm.h (SCM_P): Corrected to run under traditional C.
7032 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7035 * async.c: Calls to scm_sysintern corrected.
7037 * async.h (scm_async_clock): Redundant declaration removed.
7039 * continuations.c (scm_dynthrow): Redundant declaration removed.
7041 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7042 Definition typos corrected.
7044 * debug.h: Missing declarations of functions in debug.c added
7047 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7048 Missing declarations to functions in eval.c added.
7050 * filesys.c: Possibly uninitialized variable rv.
7052 * gc.h (scm_object_addr, scm_unhash_name): Missing
7053 declarations of functions defined in gc.c added.
7055 * genio.c: Possible typos str_data -> wstr_data. ???
7057 * genio.c: Possibly unintended shadowing of local variable
7058 `int c' (gotos out of scope of inner `c'). ???
7060 * init.c: Uninitialized `SCM last' may be used.
7062 * ioext.h: (scm_sys_isatty_p): Typo.
7064 * list.h (scm_list_head): Missing prototype for function in
7067 * numbers.c (scm_two_doubles): Changed from extern to static
7068 (is used only within numbers.c).
7070 * numbers.h: Repeated declarations removed.
7072 * ports.h (scm_close_all_ports_except): Declaration for the
7073 function defined in ports.c added.
7075 * posix.h: Missing declarations added.
7077 * procs.h (scm_make_subr_opt): Missing declaration added.
7079 * socket.h (scm_sys_gethost): Missing declaration added.
7081 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7083 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7084 Missing declarations added.
7086 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7088 * struct.c: Uninitialized variable `SCM answer' may be used.
7090 * unif.c (l2ra): Declaration prototype.
7092 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7093 defined in ramap.c).
7095 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7096 Redundant declarations removed (they are in ramap.h).
7098 * variable.h (scm_make_udvariable,
7099 scm_make_undefined_variable): Declaration corrected to
7100 correspond variable.c.
7102 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7103 Missing declarations added.
7105 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7107 * Makefile.in (distclean): Don't forget to delete fd.h.
7109 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7111 * fd.h.in, tags.h: Trivial cleanups.
7113 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7114 marksweep.h just declared functions from gc.c.
7115 * gc.h, libguile.h: Don't #include "marksweep.h".
7116 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7117 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7118 dependencies updated.
7120 * libguile.h: Don't #include "files.h"; it's been deleted.
7122 * files.c (scm_sys_delete_file): Moved to filesys.c.
7123 File is now empty; deleted.
7125 * filesys.c: scm_sys_delete_file is now here. Remove
7126 #if's; they seem to rely on remnants of an old portability
7127 regimen. If the problems come up again, solve them properly,
7128 using autoconf. Specifically: Don't test M_SYSV, and #define
7129 remove to be unlink if it's #defined; don't use remove just
7130 because HAVE_STDC_HEADERS is #defined.
7131 * filesys.h: Add declarations for scm_sys_delete_file.
7132 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7133 files.o, files.h, files.c, and files.x.
7134 * init.c: Don't #include "files.h", and don't call scm_init_files.
7136 Use SCM_P instead of PROTO; the latter intrudes on the user's
7138 * params.h: Deleted; definition of SCM_P moved to...
7139 * __scm.h: ... here, where it replaces PROTO macro.
7140 * libguile.h, smob.h: Don't #include "params.h".
7141 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7142 smob.h: Fix prototypes accordingly.
7143 * Makefile.in: Update dependencies.
7144 (inner_h_files): Remove params.h.
7146 * gc.c: #include "gc.h"; every module should include its header,
7147 to let the compiler cross-check the declarations against the
7150 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7151 simpos.h: #include "libguile/__scm.h".
7153 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7155 * init.c: Don't forget to #include smob.h and init.h.
7156 * Makefile.in: Dependencies updated.
7158 * smob.h: Use PROTO instead of #if __STDC__.
7160 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7162 * __scm.h: Doc fixes.
7164 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7165 <angles>; this allows `make depends' to work properly.
7167 * libguile.h: #include smob.h and pairs.h before the others; they
7168 define typedefs used by other headers.
7170 C files should #include only the header files they need, not
7171 libguile.h (which #includes all the header files); the pointless
7172 recompilation was wasting my time.
7173 * Makefile.in (all .o dependency lists): Regenerated.
7174 * libguile.h: Don't try to get a definition for size_t here...
7175 * __scm.h: Do it here.
7176 * _scm.h: Since this is the internal libguile header, put things
7177 here that all (or a majority) of the libguile files will want.
7178 Don't #include <libguile.h> here; that generates dependencies on
7179 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7180 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7181 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7272 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
7273 "smob.h", "genio.h", "eval.h", "chars.h".
7274 * variable.c: Get "variable.h", "smob.h", "genio.h".
7275 * vectors.c: Get "vectors.h", "eq.h".
7276 * version.c: Get "version.h".
7277 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7278 * weaks.c: Get "weaks.h".
7280 * stackchk.h: #include "libguile/debug.h",
7282 * print.h, read.h: #include "options.h", since everyone who uses
7283 either of these files will need that.
7285 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7286 anyone who uses this file will need them to define the smob
7287 printing functions. Also, get markers.h, since people will need
7288 to #define the mark functions.
7290 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7291 * ports.h: ... to here.
7293 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7294 don't rely on archaic C default type rules.
7296 * fports.h: #include "libguile/ports.h", since you need that in
7297 order to parse this.
7299 * genio.h: #include "libguile/print.h", because you need that to
7300 parse this; don't bother #including "ports.h", since print.h gets
7303 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7305 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7306 this; it's now a reference to an element of *scm_root.
7308 * debug.h: Don't #include "options.h"; the compiler won't be able
7309 to find that once the headers are installed; instead, #include
7310 "libguile/options.h".
7311 * gc.h: Same, with marksweep.h.
7312 * mbstrings.h: Same, with symbols.h.
7313 * scmhob.h: Same, with _scm.h.
7314 * smob.h: Same, with params.h.
7316 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7317 C files; there's no need for this, and it forces recompilations
7320 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7322 * error.c (scm_error): declare scm_error_callback.
7324 * error.h: prototype for scm_error_callback.
7326 * __scm.h: define lgh_error.
7327 (SCM_SYSERROR): redefine using lgh_error.
7329 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7331 * error.c (scm_error): new procedure.
7333 * error.h: prototype for scm_error.
7335 * Makefile.in (install): install scmconfig.h from the current
7336 directory, not $(srcdir).
7338 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7340 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7341 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7342 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7343 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7344 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7345 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7346 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7347 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7348 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7349 vports.h, weaks.h: #include "libguile/__scm.h", not
7350 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7351 dependencies are within libguile properly.
7353 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7355 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7356 when scmconfig.h doesn't exist.
7358 * load.c (scm_sys_try_load): Correct spelling.
7360 * feature.c (scm_loc_features): Make this static.
7362 * Makefile.in (libpath.h): Omit trailing slash from path. We
7363 shouldn't require it of users, so why put it here?
7365 Move code to initialize and search %load-path from ice-9 to C
7366 code, so we can use the load-path to find the ice-9 boot code;
7367 this makes it easier to run Guile without installing it. See
7368 corresponding changes in guile/Makefile.in.
7369 * feature.c: Move stuff concerned with the load path to load.c.
7370 (scm_compiled_library_path): Deleted.
7371 Don't #include libpath.h here.
7372 * feature.h: Don't mention scm_compiled_library_path.
7373 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7374 <sys/stat.h>, and <unistd.h> (if present).
7375 (R_OK): #define if the system hasn't deigned to.
7376 (scm_loc_load_path): New variable.
7377 (scm_init_load_path, scm_sys_search_load_path,
7378 scm_sys_try_load_path): New functions.
7379 (scm_init_load): Initialize scm_loc_load_path to point to the
7380 value cell of the Scheme %load-path variable.
7381 * load.h: Add declarations for scm_sys_search_load_path,
7382 scm_sys_try_load_path.
7383 * init.c: Call scm_init_load_path.
7384 * Makefile.in (feature.o, load.o): Dependencies updated.
7386 * load.c, load.h: Rewrite using PROTO macro.
7388 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7390 * gc.c (scm_cellp): New function: C predicate to determine if an
7391 SCM value can be regarded as a pointer to a cell on the heap.
7393 * gc.h: Added declaration of scm_cellp.
7395 * gdb_interface.h: New file: The GDB interface header from the GDB
7398 * gdbint.c: New file: GDB interface.
7400 * gdbint.h: New file: GDB interface.
7402 * libguile.h: Added #include <libguile/gdbint.h>.
7404 * init.c (scm_boot_guile): Added scm_init_gdbint.
7406 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7407 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7408 found if object files and source are kept separate).
7410 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7412 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7414 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7416 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7417 TK_SRC_DIR; they're not relevant any more.
7419 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7420 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7422 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7424 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7425 search path, so we can find the <libguile/MUMBLE.h> headers.
7427 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7429 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7430 implicit in the .c.o rule.
7431 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7434 Put the library path in a header file, instead of passing it on
7435 the command line in every compilation.
7436 * Makefile.in (libpath.h): New target.
7437 (feature.o): Depend on libpath.h.
7438 (clean): Delete libpath.h.
7439 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7440 * feature.c: ... #include "libpath.h" here.
7441 * .cvsignore: Ignore libpath.h.
7443 Don't install the unwashed masses of Guile header files in the
7444 main #include path; put most of them in a subdirectory called
7445 'libguile'. This avoids naming conflicts between Guile header
7446 files and system header files (of which there were a few).
7447 * Makefile.in (pkgincludedir): Deleted.
7448 (innerincludedir): New variable; this and $(includedir) are enough.
7449 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7450 (installed_h_files): Divide this up. Now this variable lists
7451 those header files which should go into $(includedir) (i.e. appear
7452 directly in the #include path), and ...
7453 (inner_h_files): ... this new variable says which files appear in
7454 a subdirectory, and are referred to as <libguile/mumble.h>.
7455 (h_files): List them both.
7456 (install): Create innerincludedir, not pkgincludedir. Put
7457 the installed_h_files and inner_h_files in their proper places.
7458 (uninstall): Corresponding changes.
7459 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7460 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7461 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7462 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7463 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7464 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7465 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7466 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7467 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7468 vports.h, weaks.h: Find __scm.h in its new location.
7469 * __scm.h: Find scmconfig.h and tags.h in their new locations
7470 (they're both "inner" files).
7472 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7474 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7476 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7478 * posix.c: Doc fixes.
7480 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7482 * socket.c: Don't include a prototype for inet_aton; just use a
7483 K&R style declaration, to avoid warnings but minimize the chance
7484 of conflicts with the system.
7486 On NextStep, <utime.h> doesn't define struct utime, unless we
7487 #define _POSIX_SOURCE before #including it.
7488 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7489 * acconfig.h: New comment text for above CPP symbol.
7490 * configure.in: Call it.
7491 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7493 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7495 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7496 testing for __EMX__.
7498 * posix.c: #include <libc.h>, if it exists.
7500 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7501 don't even know if the latter exists.
7503 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7504 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7505 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7507 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7509 (scm_init_posix): Use them when initializing the Scheme constants
7512 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7514 * Makefile.in (libdir, includedir, bindir): Use the
7515 autoconf-supplied values, instead of deriving them ourselves.
7516 (pkgincludedir, datadir, pkgdatadir): New variables.
7517 (install, uninstall): Put the header files in a special
7518 subdirectory, not in the main search path.
7520 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7521 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7523 * Makefile.in (IMPLPATH): Deleted; never used.
7525 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7526 on the Tcl/Tk source any more.
7527 (INCLUDE_CFLAGS): Remove references to the above.
7529 * Makefile.in (version.o): Corrected dependencies.
7531 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7533 * libguile.h: #include "version.h"
7535 * init.c (scm_boot_guile): Call scm_init_version.
7536 * gscm.c (gscm_run_scm): Call scm_init_version.
7538 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7539 GUILE_VERSION): AC_DEFINE these.
7540 (acconfig.h): #undef the above symbols.
7542 * Makefile.in (libobjs): Add version.o.
7543 (installed_h_files): Add version.h.
7544 (c_files): Add version.c.
7545 (gen_c_files): Add version.x.
7546 (version.o): New rule.
7547 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7548 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7556 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7557 weaks.o): Add version.h to dependency lists.
7558 (markers.o): Remove duplicate rule.
7560 * version.h: New file.
7562 * version.c: New file.
7564 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7566 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7567 array; use it appropriately. Since GCC is quite happy to
7568 subscript functions, it never warned us about this; we should use
7569 -Wpointer-arith in the future. I guess we never tested
7572 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7574 * socket.c: Doc and copyright fixes.
7576 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7578 * debug.c: Fixed and improved gdb support.
7580 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7582 * socket.c: Added declaration of inet_aton to avoid compiler
7583 warning. (Hope this solution is correct.)
7585 * stime.c: Added declaration of ftime. (This is missing in
7588 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7590 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7592 * Makefile.in (c_files): add strerror.c.
7594 * strerror.c: new file from Emacs' sysdep.c.
7595 maybe configure should also check for sys_errlist.
7597 * configure.in (AC_REPLACE_FUNCS): add strerror.
7599 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7601 * debug.c (scm_init_debug): Added initialization for
7602 scm_evaluator_traps.
7604 * debug.h, debug.c: Various name changes.
7605 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7606 "debug-options-interface". See commentary in options.c.
7608 * options.h, options.c: Options now have documentation strings.
7609 Also added a long explanatory commentary.
7611 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7614 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7615 last_debug_info_frame is now updated in all cases.
7617 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7620 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7622 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7623 Added option STACK_CHECKING.
7625 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7627 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7629 * __scm.h: Removed symbols for debugging support.
7631 * acconfig.h: Added symbols for debugging support.
7633 * configure.in: Added user option for debugging support.
7634 --enable-debug will include the debugging code into libguile.a.
7636 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7637 scm_relocate_chunk_to_heap.
7639 * debug.c: New file: low-level debugging support. It also
7640 includes support for debugging with gdb. (The extensions to gdb
7641 are written by Per Bothner at Cygnus.)
7643 * debug.h: New file: low-level debugging support.
7645 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7646 argument pairs. Extensive modifications to the debugging
7647 evaluator. Added "SECTION:" commentaries to clarify what happens
7648 when, during double compilation. Renamed EVALIMP --> EVALIM.
7649 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7650 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7651 the beginning of the file. New procedure: scm_unmemocopy.
7652 Added some global state variables needed by the debugging
7653 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7654 check_entry, check_apply, check_exit, debug_options and
7655 evaluator_traps. New acro: undefine.
7657 * eval.h: Renamed EVAL --> XEVAL.
7659 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7660 --> scm_make_weak_key_hash_table.
7662 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7663 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7665 * libguile.h: Conditionally include debug.h
7667 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7668 scm_object_properties shouldn't return handle. `handle' now gets
7669 initialized in scm_set_object_properties_x. scm_object_properties
7670 doesn't any longer create an entry in scm_object_whash.
7672 * options.c: New file: handling of run time options.
7674 * options.h: New file: handling of run time options.
7676 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7678 * print.c: New procedure: scm_print_options
7680 * print.h: Defines for print options.
7682 * read.c: New procedure: scm_read_options
7684 * read.h: Defines for reader options.
7686 * root.h: Added scm_source_whash among scm_sys_protects.
7688 * srcprop.c: New file: source properties.
7690 * srcprop.h: New file: source properties.
7692 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7693 (Bug found by A. Green.)
7695 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7697 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7699 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7701 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7703 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7704 and should be called by the final client.
7706 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7708 * gc.h: Use the PROTO macro when declaring functions.
7709 * gc.c: Use the PROTO macro when declaring static functions.
7710 Remove the CPP hair around function definitions.
7712 * gc.c (scm_init_storage): Initialize scm_asyncs.
7714 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7715 preprocessor symbol; "__scm.h" is where it might get #defined.
7716 * __scm.h: Similar: #include <scmconfig.h> before testing
7719 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7721 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7723 * init.c (scm_boot_guile): Add init_func argument; call
7724 (*init_func) instead of calling scm_appinit; it's ucky to
7725 hard-code names for the user's procedures.
7726 * init.h (scm_boot_guile): Adjust declaration.
7728 * __scm.h (PROTO): New macro, for declaring functions with
7731 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7732 eliminate all the __STDC__ conditionals.
7733 (scm_boot_guile): Add declaration.
7734 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7735 Remove __STDC__ conditionals around function definitions; the
7736 declarations in init.h will provide the same information, more
7739 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7740 complain about it in the error message; the error message is
7741 adequate without that note, and there's nothing the user can do
7744 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7746 * Makefile.in (ancillary): Drop def.sed.
7748 * posix.c (scm_init_posix): Use numeric values, rather than
7749 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7750 F_OK. The symbols aren't available on some systems, and I'm
7751 pretty sure their values are fixed by common widespread practice.
7752 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7754 More functions unavailable on some systems.
7755 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7756 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7758 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7759 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7760 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7761 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7762 stub that signals an error as the #else.
7764 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
7766 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>

7816 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
7818 Changes for NeXT, suggested by Robert Brown.
7819 * configure.in: Call AC_TYPE_MODE_T.

7821 NeXT. Put header file list in alphabetical order.
7822 * configure, scmconfig.h.in: Regenerated.
7823 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.

7853 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7855 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
7856 This is necessary on Ultrix, and doesn't hurt portability.
7858 * Makefile.in (dist-dir): New target, implementing a new dist system.
7859 (installed_h_files): Put in alphabetical order.
7860 Remove duplicate entries for markers.h and unif.h.
7861 (c_files): Remove duplicate entries for markers.c.
7862 (ancillary): Renamed from anillery; all uses changed. Remove
7863 PLUGIN; it's a directory, and needs special treatment in dist-dir.
7864 Remove all the ../doc/* files; doc/Makefile.in handles that.
7866 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
7868 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
7869 every if must have an else, or else the whole command has a
7870 non-zero exit code whenever the if's condition is false.
7872 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

7934 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
7936 * ports.c (scm_ports_prehistory): size malloced here doesn't
7937 matter so long as it is non-0 (got rid of "* 4").
7939 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
7941 * gscm.h: gscm_mkarray eliminated (presumably was not being used
7942 since its definition was bogus).
7944 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
7946 * mallocs.[ch]: back again (for rx at least).
7948 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
7950 * ports.c: removed functions relating to the mapping between ports
7951 and descriptors. (That stuff is unix-specific and should be collected
7952 in a separate library).
7954 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
7955 (Tom Mckay@avanticorp.com)

7959 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
7960 handled correctly (SCM_FREEP was applied to them) -- test for
7961 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

8009 * pairs.c (scm_delq_x): never throw an error.
8011 * vectors.c (scm_make_vector): made the default vector fill argument
8012 into '() (much more useful than the previous value, "#unspecified")

8016 * ports.c (scm_add_to_port_table): Added fields
8017 to port table entries: file_name, line_num, col.
8018 Update these in open_file, gen_getc and gen_ungetc.
8019 Added procedures to access those fields.
8021 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

8155 set the multi_byte flag correctly in symbols. This is wrong.
8156 intern_obbary_soft and msymbolize should take an extra parameter.
8157 Also, weird multibyte symbols don't print correctly.
8158 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8161 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8163 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means

8166 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8168 * strings.c (scm_make_shared_substring): build'em.

8308 * _scm.h (CxR functions): #define CxR SCM_CxR => #define CxR(X) SCM_CxR(X)
8309 Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
8311 * lvectors.c (scm_lvector_set_x): avoid VELTS (VELTS (...)[..]) which
8312 can turn into an obscure gc bug.
8314 * chars.c (scm_char_p): fixed PROC call.
8316 * gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
8319 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
8321 * elisp.c (new file): dynamic scoping and other bits for
8322 elisp. Don't use this yet unless you specificly want to
8323 hack on elisp emulation.
8325 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
8326 scope created by scm_with_dynamic_bindings_operation_x, swap
8327 the bindings of that scope with the corresponding globals.
8329 * continuations.c (scm_make_cont): when a continuation is captured,
8330 relocate the continuation stack chunks registered on the wind chain
8333 Sun Jan 21 19:31:17 1996 Tom Lord <lord@beehive>
8335 * eval.c (SCM_CEVAL): if the function position evaluates
8336 to a macro, process it accordingly. (Previously, macros were
8337 handled only if the function position was a symbol naming a
8338 variable bound to a macro).
8340 Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
8342 * eval.c (scm_m_set): allow multi-variable set! like
8345 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
8347 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
8348 STREAM of ports into the port table and replaced it with a
8351 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
8353 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
8355 * mbstrings.c (new file): functions on multi-byte strings.
8357 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
8358 for multi-byte strings. Moved the string tag.
8360 * chars.h chars.c repl.c (many functions): made scm_upcase and
8361 scm_downcase functions that are safe for extended character sets.
8363 Changed the range of integer->char.
8365 Changed the type of SCM_ICHR.

8374 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
8375 know that it's safe to pass an object to gscm_get_type?)
8376 (gscm_get_type): Fix tyop in error message.
8378 * variable.c (scm_variable_ref): fixed assertion test.
8379 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
8381 * gscm.h: fixed several prototypes, notably gscm_vref.
8382 Add gscm_is_eq and temporarily commented out gscm_eq (see
8383 the note in gscm.h near gscm_eq if this change effects your

8387 * pairs.c (scm_obj_length): see next entry.
8389 * gscm.h (gscm_obj_length): A way to get an integer
8390 length for lists, strings, symbols (treated as strings),
8391 and vectors. Returns -1 on error.
