GH		 12000-11-07 Gary Houston <ghouston@arglist.com>
2
3 * ports.c (scm_port_for_each): new proc. implements port-for-each,
4 which applies a procedure to each port in the port table.
5 ports.h: declare scm_port_for_each.
6
7 * ioext.c (scm_dup2): new proc. implements "dup2" which is a simple
8 wrapper for the dup2 system call (unlike dup->fdes or
9 primitive-move->fdes).
10 * ioext.h: declare scm_dup2.
11
12 * filesys.c (scm_close_fdes): new proc. implements "close-fdes"
13 which is a simple wrapper for close system call (unlike scm_close).
14 * filesys.h: declare for scm_close_fdes.

18 * eval.c (SCM_IM_DISPATCH), objects.c (scm_mcache_lookup_cmethod):
19 Count n_specialized + 1 turns before letting a match through.
20
21 * goops.c (scm_sys_invalidate_method_cache_x): Don't convert
22 scm_si_n_specialized from fixnum and don't take absolute value.

GH		 252000-11-04 Gary Houston <ghouston@arglist.com>
26
27 * ports.c (scm_port_p): new function, implements "port?" which
28 is mentioned in R5RS.
29 * ports.h: declare scm_port_p.

DH		 312000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
32
33 * backtrace.c (display_expression, display_error_body), fports.c
34 (prinfport), print.c (scm_iprin1): Test for symbols and strings
35 explicitly instead of using SCM_ROSTRINGP.
36
37 * backtrace.c (scm_display_error_message): Don't pass a symbol to
38 scm_simple_format. Prefer high-level output functions.
39
40 (display_error_body): When displaying procedure names, give
41 preference to the name passed as a parameter. Only if none is
42 given extract a name from the stack information.
43
44 * fports.c (scm_fdes_to_port, prinfport), gc.c (scm_gc_mark),
45 ports.c (scm_port_filename, scm_set_port_filename_x): Use
46 SCM_(SET_)?FILENAME.
47
48 * gh_data.c (gh_set_substr, gh_scm2newstr, gh_get_substr,
49 gh_symbol2newstr): Use scm_remember instead of a pair of calls to
50 scm_protect/unprotect_object.
51
52 * goops.c (make_struct_class), objects.c (scm_class_of): Struct
53 table names are symbols.
54
55 * ports.h (SCM_SET_FILENAME): Added.
56
57 * print.c (scm_iprin1): Don't use scm_puts to write symbols or
58 strings in order to treat substrings right. Reposition call to
59 scm_remember after the last use of object's data.
60
61 (scm_simple_format): Treat messages that are substrings right.
62
63 * symbols.h (SCM_ROSTRINGP): Deprecated.

DH		 652000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
66
67 * environments.c (obarray_replace, obarray_retrieve,
68 obarray_remove): Don't use '==' to compare SCM objects.
69
70 * posix.c (scm_getgroups): Don't create a redundant string.
71
0f87853a
DH		 722000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
73
74 * symbols.c (scm_sym2vcell, scm_sym2ovcell_soft,
75 scm_intern_symbol, scm_unintern_symbol): Symbol objects already
76 hold their hash values, no need to recompute them.
77
78 (scm_intern_obarray_soft): Speed up search for a matching symbol
79 by comparing the hash values first.
80
a3a32939
DH		 812000-10-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
82
83 * unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
84 allow vectors longer than SCM_LENGTH_MAX. This removes the
85 SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
86 SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
87 all of guile's code was implemented to be aware of this trick, it
88 is unlikely that it was used anyway. We can implement such a
89 feature more cleanly by using double cells for uniform vector
90 types.
91
92 (scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
93 straightforward predicates.
94
95 (scm_dimensions_to_uniform_array): Require that for dimensions
96 given as lower-bound/upper-bound pairs the upper-bound is never
97 less than the lower bound.

118 strports.c (scm_mkstrport), symbols.c
119 (scm_string_to_obarray_symbol), vports.c (scm_make_soft_port):
120 Don't accept symbols as input parameters. Use SCM_STRING_LENGTH
121 instead of SCM_ROLENGTH.
122
123 * dynl.c (scm_dynamic_link, scm_dynamic_func), error.c
124 (scm_error_scm), filesys.c (scm_chown, scm_chmod, scm_open_fdes,
125 scm_stat, scm_link, scm_rename, scm_delete_file, scm_mkdir,
126 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,

133 scm_regexp_exec), simpos.c (scm_system, scm_getenv), stime.c
134 (setzone, scm_strftime, scm_strptime), vports.c
135 (scm_make_soft_port): Use SCM_STRING_COERCE_0TERMINATION_X to
136 make sure the characters of a string are followed by a \0.
137 Further, use SCM_STRING_CHARS instead of SCM_ROCHARS on the
138 resulting string.
139
140 * dynl.c (scm_make_argv_from_stringlist), posix.c
141 (scm_convert_exec_args): Aligned to match each other.
142
143 * dynl.c (scm_coerce_rostring): Removed.
144
145 (scm_dynamic_func): Changed the comment to reflect that the
146 function name has to be a string. Further, hide implementation
147 details from the scheme comment.
148
149 * error (scm_error_scm): Don't accept a symbol as message
150 parameter. Fix substring handling.
151
152 * posix.c (environ_list_to_c): Use memcpy to copy environment
153 strings. Handle substrings which don't have a trailing \0.
154
155 * symbols.h (SCM_LENGTH, SCM_ROLENGTH, SCM_SUBSTRP,
156 SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR):

DH		 1642000-10-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
165
166 * random.c: Include unif.h.
167
168 * strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
169 intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
170 will be necessary, even after copy-on-write strings will be added
171 to guile, but the current naming is inappropriate.
172
173 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
174 scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as
175 input parameters. Further, the functions that test for equality
176 are rewritten to compare from back to front, the others are also a
177 little bit more polished.

180
181 This change merges the GOOPS code into Guile. However, GOOPS
182 is still not initialized until someone asks for the module.
183 We need to optimize GOOPS initialization time before initializing
184 it together with the rest of libguile. We also need to add the
185 C API + primitive methods. Then we can start using it to
186 modularize Guile, implement a real exception system etc.
187
188 * goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
189 scm_make_port_classes, scm_change_object_class,
190 scm_memoize_method): Changed to ordinary functions (was plugin
191 slots).
192
193 * goops.c (wrap_init, scm_wrap_object): Unconditionally use
194 SCM_STRUCT_GC_CHAIN.
195 (scm_goops_version): Removed.
196 (scm_oldfmt): and all uses of it: Removed.
197 (scm_shared_array_root, scm_shared_array_offset,
198 scm_shared_array_increments): Removed.
199 (scm_init_goops): No need to support two arg mutex init.
200 Removed #include "versiondat.h", #include "goops.h".
201
202 * goops.h: Removed various superfluous conditions.
f4553de8
MD		 203 Renamed class --> cls, new --> newinst in order to accomodate
204 C++.
14f1d9fe
MD		 205
206 * init.c (scm_init_guile_1): Call the goops module registration
207 function.
208 Added #include "libguile/goops.h".
209
210 * Makefile.am (libguile_la_SOURCES): Added goops.c
211 (DOT_X_FILES): Added goops.x
212 (DOT_DOC_FILES): Added goops.doc
213 (modinclude_HEADERS): Added goops.h

DH		 2152000-10-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
216
217 * gc.c (scm_igc): Remove references to scm_vector_set_length_x.
218
219 (scm_gc_sweep): SCM_CONTREGS is never NULL.
220
221 * gc.c (scm_gc_sweep), vectors.c (scm_make_vector): Don't
222 allocate/free memory for zero length vectors.
223
224 * vectors.[ch] (scm_vector_set_length_x): Deprecated.
225

DH		 2262000-10-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
227
228 * alist.c (scm_assq_ref): Add a suggestion about how to deal with
229 this function when the API gets reviewed.
230
231 * async.c (SET_ASYNC_GOT_IT): Use SCM_TYP16 instead of doing bit
232 operations directly.
233
234 * dynl.c (scm_coerce_rostring), filesys.c (scm_link,
235 scm_copy_file), fports (scm_open_file), hash.c (scm_hasher),
236 posix.c (scm_getpwuid), print.c (scm_iprin1), simpos.c
237 (scm_system), strings.c (scm_string_ref, scm_substring,
238 scm_string_append), strop.c (scm_string_copy), struct.c
239 (scm_make_struct_layout), symbols.c (scm_gensym, scm_gentemp),
240 symbols.h (SCM_COERCE_SUBSTR): Use SCM_STRING_LENGTH instead of
241 SCM_ROLENGTH if the object is known to be a string or substring.
242
243 * eval.c (scm_lookupcar): Use SCM_ITAG7 instead of doing bit
244 operations directly.
245
246 * filesys.c (scm_dirname, scm_basename): Don't create shared
247 substrings as these are going to disappear from guile.
248
249 * gc.c (scm_gc_sweep): Use SCM_UVECTOR_LENGTH instead of
250 SCM_HUGE_LENGTH. (The SCM_HUGE_LENGTH mechanism does not work
251 correctly anyway.)
252
253 * gc.h (SCM_FREEP, SCM_NFREEP): Deprecated.
254
255 * read.c (scm_flush_ws): Don't compare SCM values directly.
256
257 * root.c (scm_make_root), root.h (scm_root_state): Removed
258 system_transformer and top_level_lookup_closure_var from struct.
259 (Since eval is now R5RS, binary compatibility is not granted
260 anyway.)
261
262 * simpos.c (scm_system): Fix condition.
263
264 * strings.c (scm_string_length, scm_string_ref, scm_substring,
265 scm_string_append), strop.c (scm_string_copy), struct.c
266 (scm_make_struct_layout, scm_make_vtable_vtable), symbols.c
267 (scm_gensym, scm_gentemp): Replace SCM_VALIDATE_STRINGORSUBSTR
268 with SCM_VALIDATE_STRING, since they do the same thing.
269
270 * strings.h (scm_make_shared_substring): Deprecated.
271
272 * tags.h (SCM_ITAG7): Added.
273
274 * validated.h (SCM_VALIDATE_STRINGORSUBSTR): Deprecated.

277
278 * init.c (scm_init_guile_1, invoke_main_func): Call
279 scm_load_startup_files in scm_init_guile_1, not in
280 invoke_main_func.
281

MV		 2822000-10-18 Marius Vollmer <mvo@zagadka.ping.de>
283
c6ba6ce6 284 * print.c (grow_ref_stack): Pass a INUM to scm_make_vector as the
31535422 285 size, not a naked int. Thanks to Brad Knotwell!

293 Deprecated.
294
295 (scm_memq, scm_memv, scm_member): Inline the sloppy code.

66ca9392
MV		 3022000-10-11 Marius Vollmer <mvo@zagadka.ping.de>
303
304 * gc_os_dep.c: Added real implementation based on code from Boehms
305 collector. This is not well tested yet.
306
307 * gc.h (scm_get_stack_base): Added prototype.
308 * init.c (scm_get_stack_base): Removed prototype.

DH		 3102000-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
311
312 * random.c (scm_seed_to_random_state): Replace SCM_LENGTH with
313 the appropriate SCM_<type>_LENGTH macro.
314
315 (vector_scale, vector_sum_squares, scm_random_solid_sphere_x,

323
324 (scm_ra_matchp, scm_ramapc, ramap, rafe, scm_array_index_map_x,

326 length of a vector object generically.

694 This patch unifies the formerly distinct ssymbol and msymbol types
695 to a common symbol type scm_tc7_symbol. The representation of the
696 new symbol type uses a double cell with the following layout:
697 <type/length, chars, raw_hash, prop-pair>, where the car of
698 prop-pair holds the symbol's function property and the cdr of
699 prop-pair holds the symbol's other properties. In the long run,
700 these properties will be removed. Then, the generic property
701 functions will be uses.
702
703 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c

8422000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
843
844 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
845 properties.h and properties.doc in the suitable places.
846
847 * init.h (scm_init_guile): New prototype.
848
849 * init.c (scm_init_guile, scm_init_guile_1): New interface for
850 initializing Guile that does return to the caller.
851 (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
852 Do not establish a catch-all, this is no longer needed.
853
854 * root.h (scm_properties_whash): New `sys_protect', used in
855 properties.c.
856
857 * throw.c (scm_ithrow): Perform catch-all handling here when no
858 suitable handler has been found. That way, we don't have to rely
859 on the user establishing a catch-all, which might be difficult for
860 him if he is using scm_init_guile instead of scm_boot_guile.

875 docstring.
876
877 * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
878 fixes: `@dots' changed to `@dots{}'.

881 substring-move-left! and substring-move-right!.

890 inserted.
891
892 * ramap.c (scm_array_copy_x): Docstring: add @deffnx line for
893 array-copy-in-order!.

906
907 the following changes let Guile get rid of the `allocated' cell
908 state.
909
910 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
911 type.
912
913 * tags.h (scm_tc16_allocated): removed.
914
915 * gc.h: removed now-obsolete comments about the `allocated' cell
916 state.
917 (SCM_NEWCELL): don't change cell type to `allocated'.
918 (SCM_NEWCELL2): ditto.
919
920 * gc.c (scm_mark_locations): mark freecells too, and don't worry
921 about any possible false positives.
922 (scm_debug_newcell): don't change cell type to `allocated'.
923 (scm_debug_newcell2): ditto.
924 (scm_gc_for_newcell): ditto.

MD		 929 * gdbint.c (gdb_print): Removed superfluous macro definition.
930
0745d387
MD		 931 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
932 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
933 string, not a symbol. (`make-vtable-vtable' needs to append this
934 string to another string and then pass it through
935 `make-struct-layout'.)
936
937 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
938 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
939
940 * struct.c (scm_make_struct_layout): Removed reference to
941 "read-only string" in comment; Check that argument is a string.
942 (scm_make_vtable_vtable): Check that argument is a string.
943
69b5f65a
MD		 944 * environments.c (scm_init_environments): All internal includes in
945 libguile must use the prefix "libguile/" in path names since inly
946 the top-level source directory is on the include list. (That, in
947 turn, is because we want to distinguish between system header
948 files and hedares files internal to libguile.)
949
950 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
951 Deprecated.
952 (scm_string_length, scm_string_ref, scm_substring,
953 scm_string_append): Don't accept symbols as arguments (R5RS).

NJ		 9552000-08-25 Neil Jerram <neil@ossau.uklinux.net>
956
957 * ports.c (scm_set_port_column_x): Fix docstring so that it
958 mentions set-port-line! rather than set-port-column! twice.
959
960 * guardians.c (scm_make_guardian): Remove spurious . from doc string.

967
968 (scm_boot_guile_1): Initialize the environments.

971 goes to Jost Boekemeier.

980 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
981 (scm_set_smob_apply): New function.
982 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
983 scm_smob_apply_3): New functions.
984 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.

MD		 9872000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
988
989 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
990 also here. (This is supposed to make sure that scmconfig.h is
991 built before all sources in order to prevent that everything has
992 to be rebuilt again. Hope it works---I'm just guessing. :)
993
994 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
995
38525772
MD		 9962000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
997
998 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
999 extra tests. (GUILE_DEBUG is only supposed to make extra
1000 debugging functions available.)

1010 fallen through the cracks in the merge. thanks to Shuji Narazaki!
1011
005b5978
ML		 1012 * gc.h: removed some stuff that broke compilation for people and
1013 wasn't actually needed anyway.

1038
1039 this changes the Guile GC to use cards (aka "chunklets").
005b5978 1040 (most of the ideas and some of the code are by Greg Harvey, though
bbe6d8db
ML		 1041 the code is probably unrecognizable now. the original chunklet
1042 proposal, way back, is by Dale Jordan).
dc16aa36
ML		 1043
1044 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
1045 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
1046 some (most) of these are probably going to be deprecated.
1047
1048 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
1049 locations anymore.
1050 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
1051 cards and bvecs (bit-vectors).
1052
1053 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
1054 account, but keeping more or less the same values as previously.
1055 added some simple helper macros.
1056 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
1057 into account.
1058 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
1059 current_mark_space_offset, mark_space_head, get_bvec,
1060 clear_mark_space): new functions and supporting variables, types
1061 and macros that implement mark space management.
1062 (scm_igc): clear the mark space (all of it) before beginning the
1063 mark phase.
1064 (scm_gc_mark): changed the tests for rogue cells, much simplified
1065 throughout (no different mark bit locations to worry about now).
1066 (scm_mark_locations): don't consider card header cells.
1067 (scm_cellp): ditto.
1068 (scm_gc_sweep): simplified.
1069 (init_heap_seg): changed to take cards into account.

ML		 10712000-08-16 Michael Livshin <mlivshin@bigfoot.com>
1072
1073 * stime.c (scm_c_get_internal_run_time): new function, same as
1074 scm_get_internal_run_time but returns a long. it's used by the GC
1075 for timekeeping, since with scm_get_internal_run_time there is a
1076 (extremely theoretical) possibility of consing.
1077 (scm_get_internal_run_time): redefined in terms of
1078 scm_c_get_internal_run_time.
1079
1080 * stime.h: added prototype for scm_c_get_internal_run_time.
1081
1082 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
1083 sweep time, total marked cells, total swept cells, and number of
1084 times GC was invoked.
1085 (gc_start_stats): renamed from scm_gc_start, made static, taught
1086 to init the new stats.
1087 (gc_end_stats): renamed from scm_gc_end, made static, taught to
1088 calculate the new stats.
1089 (scm_igc): don't call gc_start_stats unless we are sure that we
1090 are indeed going to collect. also, added some timekeeping between
1091 the mark and sweep phases.
1092 (scm_gc_sweep): count number of cells we sweep as we go.
1093
1094 * gc.h: removed prototypes for scm_gc_{start,end}.

1142 compatible.
1143 (scm_i_eval_x, scm_i_eval): New functions (replace

1189 The following changes are intended to ensure that struct instances
1190 are freed before their vtables. It's optimized for the most
1191 common case, which is freeing of struct instances.

1346
1347 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
1348 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
1349 should not be accessed via SCM_C[AD]R. Further, using dedicated
1350 macros to access free cells allows all other cell accessing macros
1351 to treat acesses to free cells as errors, thus enabling better
1352 error checks for cell accesses. SCM_FREE_CELL_P is supposed to

1366 should be used.
1367
1368 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address

1386 garbage, if still no memory available grow heap.
1387
1388 (heap_segment_table_size): Added to always reflect the actual
1389 size of the heap segment table, because scm_n_heap_segs may differ
1390 from the heap segment table size.
1391
1392 (alloc_some_heap): In case of malloc failure, react according to
1393 the new policy_on_error parameter (either return to caller or
1394 abort immediately). Further, keep heap_segment_table_size up to
1395 date.
1396

1449 errors and SCM_WRONG_TYPE_ARG to report type errors.
1450
1451 * strings.c (scm_substring): Make range checks for negative
1452 values explicit (former behaviour relied on an implicit

1468 Perform all range checks based on the input value. The former way
1469 of using the value that is assigned to the target variable fails
1470 if the assignment to the target variable itself can change the
1471 value because of type conversion.

1681 twice.
1682 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1683 an unprotected object.

MD		 1692 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1693 size_t.
1694 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1695 Ditto for `tmp_size'.
1696 (scm_addr_buffer_size): Changed type from int to size_t.
1697
1698 * random.c: #include <string.h>. (Needed by memcpy.)
1699
97ebbbca
MD		 1700 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
1701 indicating stdin, instead of "" and don't reset ARGC. This is a
1702 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
1703 it is correct, and perhaps even better.

GH		 17052000-06-14 Gary Houston <ghouston@arglist.com>
1706
1707 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not

1709 (thanks to Dale P. Smith).

1732 compiler.

9c8dca4e
MD		 1762 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1763 shouldn't use Make rules which aren't supported by most Make
1764 programs.)
d230c130
MD		 1765 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1766 want these dependencies recorded, since they would get bogus
1767 relative paths; libguile.h is only used in gh.h and guile.c.)
9c8dca4e
MD		 1768 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1769 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1770 (modinclude_HEADERS): Removed kw.h.
1771
69fc343a
MD		 1772 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1773 (The preprocessor might insert spaces before the identifier.)
1774
341f78c9
MD		 1775 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):

ML		 18022000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1803
1804 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1805 write it to the temp file first and check the CPP return code.
1806 (I introduced this bug earlier, and this probably caused people
1807 with non-GNU C preprocessors to get empty *.x files and not to
1808 have the build fail right away...).
1809
1810 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1811 -- at least my libc5-based Linux system doesn't define SIGSYS.

1828 Scheme code.

MD		 1866 * eval.c (scm_badformalsp): New static function.
1867 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1868 (Thanks to Keisuke Nishida.)
1869
2c4fc472
MD		 1870 The major reason for Guile's slow loading speed has been the fact
1871 that a chain of Scheme level procedures has been evaluated for
1872 every top-level symbol lookup during the first pass through the
1873 code.
83238bc1 1874
2c4fc472
MD		 1875 The following is a kludge which I suggested four years ago, and
1876 which I've repeatedly suggested since. Personally, I've never
1877 been bothered by Guile's slow loading speed, so I thought I would
1878 let someone else do it...
1879
1880 But since the new environments will be included first in
1881 Guile-1.5, I thought it would make people happy to get the kludge
1882 into 1.4.
83238bc1 1883
2c4fc472
MD		 1884 * modules.c: Added #include "libguile/vectors.h";
1885 Added #include "libguile/hashtab.h";
1886 Added #include "libguile/struct.h";
1887 Added #include "libguile/variable.h";
1888 Capture Scheme level `module-make-local-var!' to be used in the
1889 standard eval closure.
1890 (scm_standard_eval_closure): New primitive.
1891
1892 * modules.h (scm_standard_eval_closure): Declare.
1893
1894 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1895 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1896
1897 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1898 standard eval closures.
1899
1900 * variable.c: Code layout fixes.

1912

MD		 1913 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to

MD		 1919 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1920 abort ().
1921 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1922 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1923 the address of these expressions since they use SCM_VALIDATE_CELL.
1924 (Thanks to Bernard Urban.)
1925

CB		 19292000-06-01 Craig Brozefsky <craig@red-bean.com>
1930
1931 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1932 from GUILE-VERSION definition of LIBGUILE version. Added to
1933 libpath.h definitions for guileversion and libguileversion which
1934 both get their values from GUILE-VERSION definition.

1943
1944 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1945 mit-pthreads.c, mit-pthreads.h: Deleted.
1946
1947 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1948 references to deleted files and fsu/mit thread support in
1949 general.

DH		 19512000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1952
1953 * hooks.c (symbol_name, scm_create_hook): Restored the original
1954 behaviour of scm_create_hook. Changing it was bad as Carl
1955 R. Witty has pointed out.
1956
1957 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1958 protect the object.

DH		 19602000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1961
1962 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1963 soon not be done by scm_create_hook any longer.
1964
1965 * hooks.c (make_hook, print_hook, scm_create_hook,
1966 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1967 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1968 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1969 longer have names. As an intermediate solution, the name
1970 predicate is emulated via object properties, but use of this
1971 feature is deprecated.
1972
1973 * hooks.h (scm_free_hook): Removed, as it is never defined.

1976
894a712b
DH		 1977 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1978 Un-deprecated since otherwise user code can't determine whether a
1979 number fits into an inum any longer. The names should be changed
1980 some time, though.
1981
1982 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1983
1984 * tags.h (SCM_UNPACK_CAR): Deprecated.

1994

ML		 20362000-05-22 Michael Livshin <mlivshin@bigfoot.com>
2037
2038 * guile-doc-snarf.in: put the preprocessed file through sed to
cf00e803
ML		 2039 trim all lines to 1024 chars. I hope it doesn't break anybody's
2040 sed. we'll see. (note: this is lossy trimming, i.e. the spill
2041 isn't wrapped around but actually chopped off. this seemed to me
2042 safe because the current snarfer doesn't understand multi-line
2043 cookies anyway. in the long term, it would be nice not to depend
2044 on AWK for anything.)
a564e775 2045
83238bc1 2046 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted

2051
2052 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
cebd4392
ML		 2053 the yucky, ugly and nasty conditional compilation back. sorry,
2054 but it was either that or requiring GAWK to build Guile.
2055 (lots of places): removed the code that implemented the old GC
2056 scheme.
686765af
ML		 2057
2058 * init.c (scm_boot_guile_1): removed the code conditioned on
2059 !GUILE_NEW_GC_SCHEME.

2061 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
2062
2063 * gc.c (scm_protect_object, scm_unprotect_object): change the
2064 implementation to more efficient (at least in the time complexity
2065 sense). the calls should now also be thread-safe -- I suspect
2066 that people expect them to be. (thanks to Han-Wen Nienhuys)

ML		 2071 SCM_REALLOW_INTS before return. I really wonder about the
2072 possible interactions between hashtables, threads & GC. it

2117 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from

2413 (scm_divbigbig, scm_divbigint): Don't return zero any more to
2414 indicate that a division has a remainder, return SCM_UNDEFINED
2415 instead. It is improbable that anyone actually used these
2416 functions outside of numbers.c. For this reason and due to the
2417 change in behaviour the functions are static now. Thus, if
2418 surprisingly there are users of these functions they will at least
2419 get alarmed.

2436 if a division has a remainder.

2894 pretending to be a C struct is not helthy, and is not needed here
2895 anyway, as asyncs happily fit in one heap cell.

2897 * async.c: reflect the fact that asyncs are now represented by
2898 single heap cell each.

3284 activates strict compile time type checking for variables of
3285 type SCM.
3286 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
3287 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.

3309
3310 * tags.h: Disabled definition of SCM_VOIDP_TEST.
3311
3312 Defining SCM as void * introduces problems which haven't been
3313 handled yet. Developers who work with these issues can enable it
3314 in their working copies.
3315
3316 Disabling this definition exposes a set of newly introduced and
3317 older misuses of types which causes warning messages during
3318 compilation. We'll fix this successively.
3319
3320 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
3321 in order to obtain a value of type SCM.

3360 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
3361 __scm.h. Let's try this out and dump the old code after the
3362 threads reorganization.

3367 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
3368 made SCM values into pointers. This turned an arithmetic
3369 computation of the address of the vcell into a pointer-arithmetic
3370 one, thereby screwing up marking of structs.
3371 Bugfix 2: Removed incompletely introduced loop variable `j' used
3372 when protecting the tail array of a struct.

3641 new way of allocating heap. It makes Guile fast, but still
3642 contains bugs.
3643
3644 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3645 allocating heap. The basic idea is to trigger GC every Nth
3646 allocated cell and grow heap when free list runs out. The scheme
3647 has been extended so that GC isn't triggered until all remaining
3648 cells are used. The implementation is also prepared for
3649 development in the direction of POSIX threads.
3650
3651 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3652 SCM_EXPHEAP should return half of the heap size.

3657 configured with --enable-guile-debug.

MD		 3659 * init.c (scm_i_getenv_int): New function.
3660 (scm_boot_guile_1): Use the environment variables
3661 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3662 they exist. (This may be replaced by a Scheme level mechanism in
3663 the future.)
3664
3d8d1283 3665 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of

MD		 3675 * init.c (scm_boot_guile_1): Use same initial segment size for
3676 1-word and 2-word segments. Having the smaller size causes Guile
3677 to GC too often. Obviously something needs to be done to allow
3678 for a smaller 2-word segment without this to happen. (The amount
3679 of heap for each type should be automatically adapted to the
3680 application somehow.)

3688
3689 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3690 all of Guile basics fits into one segment and there suitable room
3691 for work.
3692 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3693 instead of 2.
3694 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3695 Freelists now contains information about object span, cells
3696 collected and amount of cells in heap segments belonging to the
3697 list.
3698 (scm_heap_size, scm_gc_cells_collected): Removed.

3707 rewrite of handling of real and complex numbers.
3708 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3709 removed along with the support for floats. (Float vectors are
3710 still supported.)
3711
3712 * tags.h (scm_tcs_bignums): Removed.
3713 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
3714 Use SCM_BIGSIGN(x) to test for sign!

3725 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
3726 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
3727 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
3728 for doubles and complex numbers.
3729 (SCM_REAL_VALUE): New selector for doubles.
3730 (scm_double_t, scm_complex_t): New types.
3731 (scm_dbl): Removed.

3745 The following changes implement primitive support for double cells
3746 (i.e. four-word cells) and change the representation of some
3747 things to multi-cells instead of cons+malloc. (Applied and
3748 modified by mdj.)
3749
3750 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3751 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3752 multi-cell access macros (used by the ones below).
3753 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3754 macros.
3755
3756 * gc.c (scm_freelist2): multi-cell freelists.
3757 (inner_map_free_list): map_free_list, parameterized on ncells.
3758 "nn cells in segment mm" was misleading for ncells > 1; changed to
3759 "objects". still print cells too, though.
3760 (scm_map_free_list): rewritten using inner_map_free_list.
3761 (scm_check_freelist): get freelist as parameter, since now we have
3762 more than one.
3763 (scm_debug_newcell2): multi-cell variants of
3764 scm_debug_newcell.
3765 (scm_gc_for_newcell): take ncells and freelist pointer as
3766 parameters.
3767 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3768 now double cells).
3769 (scm_gc_sweep): don't free the float data, since it's not malloced
3770 anymore.
3771 (init_heap_seg): didn't understand what n_new_objects stood for,
3772 so changed to n_new_cells.
3773 (make_initial_segment): new function, makes an initial segment
3774 according to given ncells.
3775 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3776
3777 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3778 {DEFER,ALLOW}_INTS thing removed.
3779
3780 * numbers.h (struct scm_dbl): changed to represent a double cell,
3781 with the number in the second half.
16d35552
MD		 3782
3783 * dynwind.c: changed the wind-guards representation to double
3784 cell.
3785
3786 * procs.c, procs.h: changed the procedure-with-setter representation
3787 to double cell.
3788
3789 * async.c, async.h: made async representation a double cell.
3790
16d35552 3791 * dynl.c: made dynamic_obj representation a double cell.

3795 * ports.c (flush_void_port): renamed to flush_port_default.
3796 (end_input_void_port): renamed to end_input_default.
3797
3798 * init.c (scm_standard_stream_to_port): create a void port instead
3799 of opening /dev/null if the standard file descriptors are bad.
3800 advantages: no portability problems, doesn't waste a file descriptor,
3801 simplifies the code (thanks to Marius for the idea).
3802
3803 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3804
3805 * void ports: make reading from a void port give EOF instead of
3806 segv:
3807 * ports.c (s_scm_sys_make_void_port): modified docstring.
3808 (fill_input_void_port): new proc.
3809 (scm_init_ports): set up fill_input_void_port.
3810 * ports.c (scm_port_non_buffer): new proc.
3811 (scm_void_port): call scm_port_non_buffer.
3812
3813 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3814 which was incorrectly appended.

3818 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3819 that we can't use autoconf for this. Autoconf itself relies on
26fba922 3820 the existence of `sed' somewhere on your path.) (Thanks to Dirk

3829
3830 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the

3849 the fdes is valid before doing anything else. check that
3850 the file descriptor supports the modes required.
3851 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3852 work: just use the default buffer size.
3853
3854 * throw.c: change an outdated comment about scm_internal_catch
3855 BODY: it doesn't take a jumpbuf arg.
3856
3857 * init.c (scm_standard_stream_to_port): install a handler in case
3858 scm_fdes_to_port throws an error. don't check here whether the
3859 file descriptor is valid, since scm_fdes_to_port will do that.
3860 set the revealed count depending on whether the port got the
3861 standard file descriptor.

3904 number of descriptors but the number of the highest descriptor +
3905 1.
3906
3907 This is a preliminary attempt at a cleanup of the threads support
3908 code. It moves things to better places, makes arguments more

3910 adds new functionality.

3922 functions. The strange names are temporary. Use scm_mutex_init
3923 and scm_cond_init instead.
3924 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3925 is ANSI C, but should we check for individual error codes in
3926 configure.in?
3927 (coop_condition_variable_timed_wait_mutex): New function.

3952 logical functions from SCM.

3976 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious

4035
4036 * ports.c: Made `set-port-column!' and `set-port-line!' each
4037 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
4038 that caused a seg fault. Also fixed `set-port-column!'s
4039 docstring. Thanks Han-Wen Nienhuys for finding the bug!

84a3df2c
GB		 4045 strings.c, variable.c: Added lots of documentation, cleaned up
4046 some existing documentation. Occasionally changed formal params
4047 to match docs. Also folded an #ifdef into the inners of a
4048 primitive instead of having two copies of the primitive
4049 (`get-internal-real-time', from stime.c)

4071 * init.c (scm_init_standard_ports): when stdout is a tty, make the
4072 current-output-port unbuffered by default. this is less confusing
4073 for interactive use. it was line-buffered because of a
4074 performance problem with unbuffered ports, but I think it will be
4075 OK now.

4080 is not defined.
4081
4082 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
4083 HAVE_TZNAME are defined, use an empty string instead of giving two
4084 spurious compile-time errors.

a00c95d9 4104

GH		 4105 * strings.c (scm_string_ref): make the 2nd argument compulsory.
4106 previously it defaulted to zero for no good reason that I can see.
4107 use a local variable for SCM_INUM (k). replace
4108 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
4109
4110 (scm_makfromstr): cosmetic changes.
4111
4112 (scm_string): Accept only chars in the list, not strings, for
4113 conformance to R5RS (particularly for list->string, which is
4114 supposed to be the inverse of string->list.) remove
4115 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
4116 scm_makstr handles the cell allocation. when reporting wrong-type
4117 arg, don't report the position as 1.
4118
4119 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.

GH		 4125 * filesys.c (scm_select, retrieve_select_type, get_element,
4126 fill_select_type, set_element): modified so that Scheme
4127 "select" tests port buffers for the ability to provide input
4128 or accept output. Previously only the underlying file descriptors
4129 were checked. Rewrote the docstring.

4139 adding "x" prefix to the line so that guile-func-name-check
4140 doesn't complain unnecessarily.

a00c95d9 4152 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
a28eb127
GB		 4153 suggests removing tag.c altogether (and using a new `class-of'
4154 instead).
4155
4156 * strings.c: Added documentation from Gregg A. Reynolds. Edited
4157 a bit by me to use FOO instead of @var{foo} and to have the
a00c95d9 4158 summary come before preconditions on input. Also dropped trailing
a28eb127
GB		 4159 (rnrs) note.
4160
4161 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
4162 function with scm_make_subr_opt w/ last arg of 0 so it is not
4163 visible at the Scheme level. Mikael says that this is the right
4164 thing because the first arg to the proc is the guts of a compiled
4165 closure and shouldn't be exposed to the Scheme level.

4249 SCM_VALIDATE_LONG_COPY
4250
4251 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of

4254 match the documentation.

4267
4268 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's

4274 * guile-doc-snarf.in: Use new $fullfilename for running
4275 guile-func-name-check, and put "$fullfilename" and "$filename" in
4276 quotes at uses to make sure re-splitting on whitespace does not
a00c95d9 4277 occur (so filenames w/ embedded whitespace would work okay, though
95aec69f
GB		 4278 I sure hope we never have to deal with that! :-) ). Thanks to
4279 Mikael for pointing out the source_dir != build_dir was broken.

GB		 4281Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
4282
4283 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
4284 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
4285 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
4286 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
4287 variants.
4288
4289 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
4290 then return whether it's an open port (was validating that it was
4291 an open port -- this was a bug I introduced back in December, but
4292 my careful reading of diffs caught it).
4293
4294 * numbers.c: Recombine the two conditional-compilation paths for
4295 all the log* primitives -- they were split based on #ifndef
4296 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
4297 some bugs and inconsistencies in the two sets of implementations.
4298 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
4299
4300 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
4301 SCM_VALIDATE_INUM_COPY once where it should've been used.
4302
4303 * fluids.c (scm_internal_with_fluids): Use
4304 SCM_VALIDATE_LIST_COPYLEN.
4305
4306 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
4307 this is questionable as it relaxes type safety, but other changes
4308 were useful and all SCM_NUM2LONG's should probably be
4309 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
4310
4311 * evalext.c: line-break change on 1 line.
4312
4313 * eval.c (nconc2last): Takes a non-empty list as its first
4314 argument, not just a list.
4315
4316 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
4317
4318Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>

4320 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
4321 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
4322 where possible.
4323
4324 * symbols.c (scm_sysintern0): Fixed the function name in a
4325 scm_misc_error invocation.
4326
4327 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
4328 use scm_return_first to ward off latent GC bug that Mikael caught.
4329
4330 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
4331 used before but should've been.

4344 redundant comment, semicolon; caught by new guile-func-name-check

4346
4347 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.

4364
4365 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
4366 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
4367 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
4368 consistency with the other macros dealing with immediate
4369 characters. (Similar to INT -> INUM change a week or so ago).

4373 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
4374 net_db.c, read.c, socket.c: Update error messages to use ~A for
4375 %s, ~S for %S to work with new `simple-format' format and be
4376 standardized better.
4377
4378 * print.h, print.c (scm_simple_format): Added `simple-format'
4379 primitive. It's the old scm_display_error, with ARGS now a rest
a00c95d9 4380 parameter, and the destination first instead of last (and a couple
7965d98f
GB		 4381 new capabilities inspired by `format' -- #t as destination means
4382 current-output-port, #f means return the formatted text as a
4383 string.
4384
4385 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
4386
4387 * backtrace.c (scm_display_error_message): Rewrote to use
4388 scm_simple_format() procedure.

4395 modifications.
4396
4397 * DYNAMIC-LINKING: Removed because it is obsolete.
4398 * dynl.c: Use ANSI prototypes.
4399 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.

4407 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
4408 against libltdl

4414
4415 * These changes should make it unnecessary to call tzset from
4416 Scheme after modifying the TZ environment variable, even if the
4417 system date facilities cache the value.
4418 * stime.c (setzone, scm_localtime): added comments.
4419 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
4420 (setzone): don't call tzset.
4421 (restorezone): call tzset only if HAVE_TZSET is defined.
4422 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
4423 doc string to indicate that this procedure isn't likely to do
4424 anything useful.
4425 (scm_localtime, scm_strftime, scm_mktime): call tzset if
4426 LOCALTIME_CACHE is defined.

4457 * backtrace.c: Fix spelling typo in a comment.

4463
4464 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4465 report the position of the argument.
4466
a00c95d9 4467 * error.h, error.c (scm_out_of_range_pos): Added this function to
5ac36451 4468 take extra "pos" argument, the position number of the errant
a00c95d9 4469 argument.
5ac36451
GB		 4470
4471 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4472
4473 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
4474 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
4475 prefers that and I'm reasonably indifferent.
4476
4477Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
4478
4479 * snarf.h: Factor out differences between C++ and non-C++ into
4480 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
4481 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
4482 Mikael's macros, below, but changed names and SCM_SNARFING no
4483 longer expands to include %%% -- that must appear in the argument
4484 so that the token appears at the call-site as a reminder).

4507
a00c95d9 4508 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2cc0f8cb

4510 macro call.

4513
4514 * scm_validate.h: Remove some redundant NIMP tests.
4515
4516 * alist.c: minimize scope of the tmp variables, and initialize
4517 them when declared. The strange SCM_NIMP tests are replaced by
4518 SCM_CONSP tests that more closely reflect the intended semantics.
4519 However, we don't get a performance penalty here, because the
4520 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
4521 extremely ugly use of ASRTGO macros was removed: The calls to
4522 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
4523 label parameter that only exists when SCM_RECKLESS is not defined.
4524 This works, because ASRTGO itself is defined in a way that it only
4525 makes use of the label parameter if SCM_RECKLESS is not defined
4526 (shudder!). Does guile make at all use of the possibility to
4527 define SCM_RECKLESS? * Codesize is likely to be reduced, since
4528 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
4529 we now only get one test.
4530
4531 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
4532 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
4533 some variables in `list?'. Fix `reverse' and `reverse!'
4534 primitives to handle improper lists better.

4539 macros and SCM_DEFINE macros to match GNU coding standards.

4546
4547 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
4548 better consistency with the names of other SCM_VALIDATE_ macros
4549 and better conformance to guile naming policy.

4551Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4552
4553 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4554 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4555 it's not the actual name of the formal).
1e484823
GB		 4556
4557 * guile-snarf.awk.in: Do argument/number mismatch checking and
4558 print warnings in an Emacs compile-mode parseable format.
4559
4560 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4561 SCM_OUTOFRANGE as 3rd argument.
4562
4563 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4564
4565 * __scm.h: Do not #define SCM_ARG* when snarfing;
4566 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4567 the former (using the number) requires the argument to match the
4568 formal in the current argument snarfing check.
4569
4570 * snarf.h: Give new definition of SCM_ASSERT when in
a00c95d9 4571 snarfing mode to output a lexically-identifiable sequence that the
1e484823
GB		 4572 guile-snarf.awk script uses to verify argument/position matching.
4573
4574 * ramap.c: Remove extraneous #undef FUNC_NAME.

4577
4578 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
a00c95d9 4579 current version of the same functionality; it writes the .x output
53fc4636
GB		 4580 to stdout instead of directly into the file.

4583
4584 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4585 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4586 redundant with the safer macros. Patch from Dirk Hermann applied
4587 by hand. Thanks Dirk!
4588
4589 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4590 uses in random.c.
4591
4592 * ramap.c: whitespace change.

4597 removals from Dirk Hermann.
4598

4600 documentation, updates to documentation. Thanks Dirk Hermann!
