DH		 12000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2
3 * environments.c (obarray_replace, obarray_retrieve,
4 obarray_remove): Don't use '==' to compare SCM objects.
5
6 * posix.c (scm_getgroups): Don't create a redundant string.

9
10 * symbols.c (scm_sym2vcell, scm_sym2ovcell_soft,
11 scm_intern_symbol, scm_unintern_symbol): Symbol objects already
12 hold their hash values, no need to recompute them.
13
14 (scm_intern_obarray_soft): Speed up search for a matching symbol
15 by comparing the hash values first.

DH		 172000-10-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
18
19 * unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
20 allow vectors longer than SCM_LENGTH_MAX. This removes the
21 SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
22 SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
23 all of guile's code was implemented to be aware of this trick, it
24 is unlikely that it was used anyway. We can implement such a
25 feature more cleanly by using double cells for uniform vector
26 types.
27
28 (scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
29 straightforward predicates.
30
31 (scm_dimensions_to_uniform_array): Require that for dimensions
32 given as lower-bound/upper-bound pairs the upper-bound is never
33 less than the lower bound.

54 strports.c (scm_mkstrport), symbols.c
55 (scm_string_to_obarray_symbol), vports.c (scm_make_soft_port):
56 Don't accept symbols as input parameters. Use SCM_STRING_LENGTH
57 instead of SCM_ROLENGTH.
58
59 * dynl.c (scm_dynamic_link, scm_dynamic_func), error.c
60 (scm_error_scm), filesys.c (scm_chown, scm_chmod, scm_open_fdes,
61 scm_stat, scm_link, scm_rename, scm_delete_file, scm_mkdir,
62 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,

70 (setzone, scm_strftime, scm_strptime), vports.c
71 (scm_make_soft_port): Use SCM_STRING_COERCE_0TERMINATION_X to
72 make sure the characters of a string are followed by a \0.
73 Further, use SCM_STRING_CHARS instead of SCM_ROCHARS on the
74 resulting string.
75
76 * dynl.c (scm_make_argv_from_stringlist), posix.c
77 (scm_convert_exec_args): Aligned to match each other.
78
79 * dynl.c (scm_coerce_rostring): Removed.
80
81 (scm_dynamic_func): Changed the comment to reflect that the
82 function name has to be a string. Further, hide implementation
83 details from the scheme comment.
84
85 * error (scm_error_scm): Don't accept a symbol as message
86 parameter. Fix substring handling.
87
88 * posix.c (environ_list_to_c): Use memcpy to copy environment
89 strings. Handle substrings which don't have a trailing \0.
90
91 * symbols.h (SCM_LENGTH, SCM_ROLENGTH, SCM_SUBSTRP,
92 SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR):

DH		 1002000-10-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
101
102 * random.c: Include unif.h.
103
104 * strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
105 intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
106 will be necessary, even after copy-on-write strings will be added
107 to guile, but the current naming is inappropriate.
108
109 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
110 scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as
111 input parameters. Further, the functions that test for equality
112 are rewritten to compare from back to front, the others are also a
113 little bit more polished.

MD		 1152000-10-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
116
117 This change merges the GOOPS code into Guile. However, GOOPS
118 is still not initialized until someone asks for the module.
119 We need to optimize GOOPS initialization time before initializing
120 it together with the rest of libguile. We also need to add the
121 C API + primitive methods. Then we can start using it to
122 modularize Guile, implement a real exception system etc.
123
124 * goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
125 scm_make_port_classes, scm_change_object_class,
126 scm_memoize_method): Changed to ordinary functions (was plugin
127 slots).
128
129 * goops.c (wrap_init, scm_wrap_object): Unconditionally use
130 SCM_STRUCT_GC_CHAIN.
131 (scm_goops_version): Removed.
132 (scm_oldfmt): and all uses of it: Removed.
133 (scm_shared_array_root, scm_shared_array_offset,
134 scm_shared_array_increments): Removed.
135 (scm_init_goops): No need to support two arg mutex init.
136 Removed #include "versiondat.h", #include "goops.h".
137
138 * goops.h: Removed various superfluous conditions.
f4553de8
MD		 139 Renamed class --> cls, new --> newinst in order to accomodate
140 C++.
14f1d9fe
MD		 141
142 * init.c (scm_init_guile_1): Call the goops module registration
143 function.
144 Added #include "libguile/goops.h".
145
146 * Makefile.am (libguile_la_SOURCES): Added goops.c
147 (DOT_X_FILES): Added goops.x
148 (DOT_DOC_FILES): Added goops.doc
149 (modinclude_HEADERS): Added goops.h

DH		 1512000-10-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
152
153 * gc.c (scm_igc): Remove references to scm_vector_set_length_x.
154
155 (scm_gc_sweep): SCM_CONTREGS is never NULL.
156
157 * gc.c (scm_gc_sweep), vectors.c (scm_make_vector): Don't
158 allocate/free memory for zero length vectors.
159
160 * vectors.[ch] (scm_vector_set_length_x): Deprecated.
161

DH		 1622000-10-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
163
164 * alist.c (scm_assq_ref): Add a suggestion about how to deal with
165 this function when the API gets reviewed.
166
167 * async.c (SET_ASYNC_GOT_IT): Use SCM_TYP16 instead of doing bit
168 operations directly.
169
170 * dynl.c (scm_coerce_rostring), filesys.c (scm_link,
171 scm_copy_file), fports (scm_open_file), hash.c (scm_hasher),
172 posix.c (scm_getpwuid), print.c (scm_iprin1), simpos.c
173 (scm_system), strings.c (scm_string_ref, scm_substring,
174 scm_string_append), strop.c (scm_string_copy), struct.c
175 (scm_make_struct_layout), symbols.c (scm_gensym, scm_gentemp),
176 symbols.h (SCM_COERCE_SUBSTR): Use SCM_STRING_LENGTH instead of
177 SCM_ROLENGTH if the object is known to be a string or substring.
178
179 * eval.c (scm_lookupcar): Use SCM_ITAG7 instead of doing bit
180 operations directly.
181
182 * filesys.c (scm_dirname, scm_basename): Don't create shared
183 substrings as these are going to disappear from guile.
184
185 * gc.c (scm_gc_sweep): Use SCM_UVECTOR_LENGTH instead of
186 SCM_HUGE_LENGTH. (The SCM_HUGE_LENGTH mechanism does not work
187 correctly anyway.)
188
189 * gc.h (SCM_FREEP, SCM_NFREEP): Deprecated.
190
191 * read.c (scm_flush_ws): Don't compare SCM values directly.
192
193 * root.c (scm_make_root), root.h (scm_root_state): Removed
194 system_transformer and top_level_lookup_closure_var from struct.
195 (Since eval is now R5RS, binary compatibility is not granted
196 anyway.)
197
198 * simpos.c (scm_system): Fix condition.
199
200 * strings.c (scm_string_length, scm_string_ref, scm_substring,
201 scm_string_append), strop.c (scm_string_copy), struct.c
202 (scm_make_struct_layout, scm_make_vtable_vtable), symbols.c
203 (scm_gensym, scm_gentemp): Replace SCM_VALIDATE_STRINGORSUBSTR
204 with SCM_VALIDATE_STRING, since they do the same thing.
205
206 * strings.h (scm_make_shared_substring): Deprecated.
207
208 * tags.h (SCM_ITAG7): Added.
209
210 * validated.h (SCM_VALIDATE_STRINGORSUBSTR): Deprecated.

215 scm_load_startup_files in scm_init_guile_1, not in
216 invoke_main_func.

630 This patch unifies the formerly distinct ssymbol and msymbol types
631 to a common symbol type scm_tc7_symbol. The representation of the
632 new symbol type uses a double cell with the following layout:
633 <type/length, chars, raw_hash, prop-pair>, where the car of
634 prop-pair holds the symbol's function property and the cdr of
635 prop-pair holds the symbol's other properties. In the long run,
636 these properties will be removed. Then, the generic property
637 functions will be uses.
638
639 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
640 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of

661 to a hash table size. Instead, the 'raw' hash value is returned.
662
663 * symbols.c (duplicate_string): New static convenience function.

669 any more. When generating symbol cells, use the new layout and
670 store the raw hash value in the symbol's cell.

MD		 867 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
868 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
869 string, not a symbol. (`make-vtable-vtable' needs to append this
870 string to another string and then pass it through
871 `make-struct-layout'.)

MD		 880 * environments.c (scm_init_environments): All internal includes in
881 libguile must use the prefix "libguile/" in path names since inly
882 the top-level source directory is on the include list. (That, in
883 turn, is because we want to distinguish between system header
884 files and hedares files internal to libguile.)

926 also here. (This is supposed to make sure that scmconfig.h is

975 this changes the Guile GC to use cards (aka "chunklets").
005b5978 976 (most of the ideas and some of the code are by Greg Harvey, though
bbe6d8db
ML		 977 the code is probably unrecognizable now. the original chunklet
978 proposal, way back, is by Dale Jordan).
dc16aa36
ML		 979
980 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
981 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
982 some (most) of these are probably going to be deprecated.
983
984 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
985 locations anymore.
986 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
987 cards and bvecs (bit-vectors).
988
989 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
990 account, but keeping more or less the same values as previously.
991 added some simple helper macros.
992 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
993 into account.
994 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,

997 and macros that implement mark space management.
998 (scm_igc): clear the mark space (all of it) before beginning the
999 mark phase.
1000 (scm_gc_mark): changed the tests for rogue cells, much simplified
1001 throughout (no different mark bit locations to worry about now).
1002 (scm_mark_locations): don't consider card header cells.
1003 (scm_cellp): ditto.

1009 * stime.c (scm_c_get_internal_run_time): new function, same as
1010 scm_get_internal_run_time but returns a long. it's used by the GC
1011 for timekeeping, since with scm_get_internal_run_time there is a
1012 (extremely theoretical) possibility of consing.
1013 (scm_get_internal_run_time): redefined in terms of
1014 scm_c_get_internal_run_time.
1015
1016 * stime.h: added prototype for scm_c_get_internal_run_time.
1017

1019 sweep time, total marked cells, total swept cells, and number of
1020 times GC was invoked.
1021 (gc_start_stats): renamed from scm_gc_start, made static, taught
1022 to init the new stats.
1023 (gc_end_stats): renamed from scm_gc_end, made static, taught to
1024 calculate the new stats.
1025 (scm_igc): don't call gc_start_stats unless we are sure that we
1026 are indeed going to collect. also, added some timekeeping between
1027 the mark and sweep phases.
1028 (scm_gc_sweep): count number of cells we sweep as we go.
1029
1030 * gc.h: removed prototypes for scm_gc_{start,end}.

1282
1283 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
1284 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
1285 should not be accessed via SCM_C[AD]R. Further, using dedicated
1286 macros to access free cells allows all other cell accessing macros
1287 to treat acesses to free cells as errors, thus enabling better
1288 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
1289 replace SCM_FREEP some time.

1300 object as const in order to make the compiler warn about code like
1301 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
1302 should be used.
1303
1304 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
1305 as an address to a non-const object, since these macros are used
1306 to allow direct write access to objects.

1319
1320 (scm_gc_for_newcell): Try to allocate new memory in three phases:
1321 grow heap if preferred, if still no memory available collect
1322 garbage, if still no memory available grow heap.
1323
1324 (heap_segment_table_size): Added to always reflect the actual
1325 size of the heap segment table, because scm_n_heap_segs may differ
1326 from the heap segment table size.
1327
1328 (alloc_some_heap): In case of malloc failure, react according to
1329 the new policy_on_error parameter (either return to caller or
1330 abort immediately). Further, keep heap_segment_table_size up to
1331 date.
1332

1377 errors.

1379 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
1380 signal range errors.
1381
1382 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
1383 error reporting (now uses original input parameter to report wrong
1384 type argument errors). Use SCM_OUT_OF_RANGE to report range
1385 errors and SCM_WRONG_TYPE_ARG to report type errors.
1386
1387 * strings.c (scm_substring): Make range checks for negative
1388 values explicit (former behaviour relied on an implicit
1389 conversion from signed to unsigned). Don't use SCM_ASSERT for
1390 range checks.
1391
1392 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,

1403 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
1404 Perform all range checks based on the input value. The former way
1405 of using the value that is assigned to the target variable fails
1406 if the assignment to the target variable itself can change the
1407 value because of type conversion.
1408
1409 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.

1414 doesn't yield any new cells. In theory this could happen if all
1415 cells allocated with NEWCELL are either in use or conservatively
1416 marked and all cluster spine cells are conservatively marked.

1680 SCM_CHARS.

1684 ptr.

1695 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1696 char).
1697
9c8dca4e
MD		 1698 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1699 shouldn't use Make rules which aren't supported by most Make
1700 programs.)
d230c130
MD		 1701 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1702 want these dependencies recorded, since they would get bogus
1703 relative paths; libguile.h is only used in gh.h and guile.c.)
9c8dca4e
MD		 1704 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1705 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1706 (modinclude_HEADERS): Removed kw.h.
1707
69fc343a
MD		 1708 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1709 (The preprocessor might insert spaces before the identifier.)
1710
341f78c9
MD		 1711 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1712 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.

1714 * smob.h (scm_smobfuns): Removed deprecated type.

1739
1740 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1741 write it to the temp file first and check the CPP return code.
1742 (I introduced this bug earlier, and this probably caused people
1743 with non-GNU C preprocessors to get empty *.x files and not to
1744 have the build fail right away...).
1745
1746 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1747 -- at least my libc5-based Linux system doesn't define SIGSYS.

1764 Scheme code.

1801

MD		 1802 * eval.c (scm_badformalsp): New static function.
1803 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1804 (Thanks to Keisuke Nishida.)
1805
2c4fc472
MD		 1806 The major reason for Guile's slow loading speed has been the fact
1807 that a chain of Scheme level procedures has been evaluated for
1808 every top-level symbol lookup during the first pass through the
1809 code.
83238bc1 1810
2c4fc472
MD		 1811 The following is a kludge which I suggested four years ago, and
1812 which I've repeatedly suggested since. Personally, I've never
1813 been bothered by Guile's slow loading speed, so I thought I would
1814 let someone else do it...
1815
1816 But since the new environments will be included first in
1817 Guile-1.5, I thought it would make people happy to get the kludge
1818 into 1.4.
83238bc1 1819
2c4fc472
MD		 1820 * modules.c: Added #include "libguile/vectors.h";
1821 Added #include "libguile/hashtab.h";
1822 Added #include "libguile/struct.h";
1823 Added #include "libguile/variable.h";
1824 Capture Scheme level `module-make-local-var!' to be used in the
1825 standard eval closure.
1826 (scm_standard_eval_closure): New primitive.
1827
1828 * modules.h (scm_standard_eval_closure): Declare.
1829
1830 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1831 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1832
1833 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1834 standard eval closures.
1835
1836 * variable.c: Code layout fixes.

MD		 18382000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1839

1841 disappeared in the change of 2000-06-01.

MD		 1846 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1847 mistake since it is not mentioned in ChangeLog.)
1848
cc0bb1ef
MD		 1849 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1850 avoid compiler warnings in gcc. (Does this work for other
1851 compilers?)
1852

1854
4ecf5aa3
MD		 1855 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1856 abort ().
1857 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1858 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1859 the address of these expressions since they use SCM_VALIDATE_CELL.
1860 (Thanks to Bernard Urban.)
1861
f8d4d8e5
MD		 1862 * dynl.c: Changed #include <ltdl.h> --> #include
1863 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1864
b6fae158
CB		 18652000-06-01 Craig Brozefsky <craig@red-bean.com>
1866
1867 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1868 from GUILE-VERSION definition of LIBGUILE version. Added to
1869 libpath.h definitions for guileversion and libguileversion which
1870 both get their values from GUILE-VERSION definition.

DH		 18722000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1873
1874 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1875 file: Code using numbers should not be required to include
1876 smob.h.
1877
b2728432
DH		 18782000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1879
1880 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1881 mit-pthreads.c, mit-pthreads.h: Deleted.
1882
1883 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1884 references to deleted files and fsu/mit thread support in
1885 general.
1886
f8eaf8b9
DH		 18872000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1888
1889 * hooks.c (symbol_name, scm_create_hook): Restored the original
1890 behaviour of scm_create_hook. Changing it was bad as Carl
1891 R. Witty has pointed out.
1892
1893 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1894 protect the object.
1895

DH		 18962000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1897
1898 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1899 soon not be done by scm_create_hook any longer.
1900
1901 * hooks.c (make_hook, print_hook, scm_create_hook,
1902 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1903 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1904 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1905 longer have names. As an intermediate solution, the name
1906 predicate is emulated via object properties, but use of this
1907 feature is deprecated.
1908
1909 * hooks.h (scm_free_hook): Removed, as it is never defined.

1912
894a712b
DH		 1913 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1914 Un-deprecated since otherwise user code can't determine whether a
1915 number fits into an inum any longer. The names should be changed
1916 some time, though.
1917
1918 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1919
1920 * tags.h (SCM_UNPACK_CAR): Deprecated.

1930

1954
1955 * eval.c (scm_force): Add documentation.

a564e775
ML		 19722000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1973
1974 * guile-doc-snarf.in: put the preprocessed file through sed to
cf00e803
ML		 1975 trim all lines to 1024 chars. I hope it doesn't break anybody's
1976 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1977 isn't wrapped around but actually chopped off. this seemed to me
1978 safe because the current snarfer doesn't understand multi-line
1979 cookies anyway. in the long term, it would be nice not to depend
1980 on AWK for anything.)
a564e775 1981
83238bc1 1982 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
a564e775
ML		 1983 the previous change to this macros, after deciding to torture the
1984 snarfer instead.

1987
1988 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
cebd4392
ML		 1989 the yucky, ugly and nasty conditional compilation back. sorry,
1990 but it was either that or requiring GAWK to build Guile.
1991 (lots of places): removed the code that implemented the old GC
1992 scheme.
686765af
ML		 1993
1994 * init.c (scm_boot_guile_1): removed the code conditioned on
1995 !GUILE_NEW_GC_SCHEME.
1996
1997 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1998
1999 * gc.c (scm_protect_object, scm_unprotect_object): change the
2000 implementation to more efficient (at least in the time complexity
2001 sense). the calls should now also be thread-safe -- I suspect
2002 that people expect them to be. (thanks to Han-Wen Nienhuys)
cebd4392
ML		 2003 (lots of places): removed the code that implemented the old GC
2004 scheme.

ML		 2005
2006 * hashtab.c (scm_hash_fn_create_handle_x): add missing
cebd4392
ML		 2007 SCM_REALLOW_INTS before return. I really wonder about the
2008 possible interactions between hashtables, threads & GC. it
83238bc1 2009 doesn't look healthy at all.

2017
2018 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
2019 debug option to verify all accesses to cells actually access
2020 objects on the heap.
2021
2022 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
2023 SCM_DEBUG_CELL_ACCESSES is set to 1.
2024
2025 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,

2053 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from

2348 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
2349 (scm_divbigbig, scm_divbigint): Don't return zero any more to
2350 indicate that a division has a remainder, return SCM_UNDEFINED
2351 instead. It is improbable that anyone actually used these
2352 functions outside of numbers.c. For this reason and due to the
2353 change in behaviour the functions are static now. Thus, if
2354 surprisingly there are users of these functions they will at least
2355 get alarmed.
2356

3252 Disabling this definition exposes a set of newly introduced and
3253 older misuses of types which causes warning messages during
3254 compilation. We'll fix this successively.
3255
3256 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
3257 in order to obtain a value of type SCM.
3258 (scm_cellp): Updated with new changes to scm_mark_locations.
3259
3260 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
3261
2f9055ea
MD		 3262 * continuations.c (scm_make_cont): Removed cast of size_t into
3263 long.
3264

MD		 3265 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.

DH		 32672000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
3268
3269 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
3270 shifting, not constant. Thanks to Dale P. Smith.
3271
3272 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
3273 for being less than zero. Decode it to a C value first. Again,
3274 thank you Dale.
3275
1ff2fa6e
DH		 32762000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
3277
3278 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
3279 non scheme values. If raw data is stored in SCM variables, it has
3280 to be accessed using SCM_UNPACK until a better solution is found.

MD		 32822000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3283
6f29dc6d
MD		 3284 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
3285 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
3286
3287 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
3288
3289 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
3290
3291 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
3292
3293 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
3294
3920465b
MD		 3295 * async.c, __scm.h: Removed lots of the old async click logic. It
3296 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
3297 __scm.h. Let's try this out and dump the old code after the
3298 threads reorganization.
3299 (set-tick-rate, set-switch-rate): Conditionally removed.

MD		 33012000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3302
3303 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
3304 made SCM values into pointers. This turned an arithmetic
3305 computation of the address of the vcell into a pointer-arithmetic
3306 one, thereby screwing up marking of structs.
3307 Bugfix 2: Removed incompletely introduced loop variable `j' used
3308 when protecting the tail array of a struct.

3317 parameter as constant, since it is not modified.
3318
3319 * symbols.c (scm_intern_obarray_soft,
3320 scm_sysintern0_no_module_lookup): Can now pass constant strings
3321 to scm_strhash without need for casting.
3322

3337 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
3338
3339 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,

MD		 3344 * gc.c (alloc_some_heap): Further improvement of minimal heap size
3345 prediction.

3348 collected cells.
3349 (gc_sweep_freelist_finish): Trigger based on two last values of
3350 freelist->collected to avoid unnecessary allocation due to
3351 temporary peaks.
bd54e664
MD		 3352 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
3353 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
3354 without extra heap allocation.

3359 already be a C value. No need to unpack it.
3360
3210f49a 3361 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
f2961ccd
DH		 3362 if we know it fits into an inum.
3363
3364 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
3365 field of long values. In contrast, SCM_VELTS accesses a field of
3366 SCM values.

MD		 33882000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3389
3390 * gc.c (adjust_gc_trigger): Improved documentation.
3391 (alloc_some_heap): Since gc_trigger is used against
3392 freelist->collected, this is the value which should be used to
3393 predict minimum growth.

DH		 33952000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>

3418 trigger adjustmeant: Take yield (freed cells) for all freelists
3419 into account.
3420 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
3421 to 50000 cell heap with 45% trigger.
3422 (scm_gc_cells_collected): Reintroduced.
3423 (SCM_HEAP_SIZE): New macro.
3424 (scm_gc_sweep): Reintroduced correct computation of
3425 scm_cells_allocated.
3426 (scm_freelist_t): Corrected commentary for field `cluster_size':
3427 Clustersize counts objects, not cells; New member
3428 `clusters_allocated'.

3449 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
50fecba9 3450 (typedef struct scm_freelist_t) moved here from gc.h, it had no
a00c95d9
ML		 3451 business being externally visible.
3452 (typedef struct scm_heap_seg_data_t) renamed from
3453 scm_heap_seg_data, to be style-compliant.
3454 (scm_mark_locations) if the possible pointer points to a
50fecba9
ML		 3455 double-cell, check that it's properly aligned.
3456 (init_heap_seg) align double-cells properly, work with the
3457 assumption that the segment size divides cleanly by cluster size.

3521 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
3522 Cluster sizes are now independent of GC trigger values.
3523 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
3524 A negative integer gives fraction of total heap size in percent.

3535 freeing of segment work with the new GC scheme. (Thanks to
bc2c8d98
MD		 3536 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME

3556 reindentation, too, and a couple formals renamed. Should

MD		 35742000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3575
3576 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
3577 new way of allocating heap. It makes Guile fast, but still
3578 contains bugs.
3579
3580 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3581 allocating heap. The basic idea is to trigger GC every Nth
3582 allocated cell and grow heap when free list runs out. The scheme
3583 has been extended so that GC isn't triggered until all remaining
3584 cells are used. The implementation is also prepared for
3585 development in the direction of POSIX threads.
3586
3587 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3588 SCM_EXPHEAP should return half of the heap size.

MD		 3595 * init.c (scm_i_getenv_int): New function.
3596 (scm_boot_guile_1): Use the environment variables
3597 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3598 they exist. (This may be replaced by a Scheme level mechanism in
3599 the future.)
3600
3d8d1283 3601 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
90e77861 3602 scm_assoc. (Thanks to Keisuke Nishida.)

3610
5ebf0091
MD		 3611 * init.c (scm_boot_guile_1): Use same initial segment size for
3612 1-word and 2-word segments. Having the smaller size causes Guile
3613 to GC too often. Obviously something needs to be done to allow
3614 for a smaller 2-word segment without this to happen. (The amount
3615 of heap for each type should be automatically adapted to the
3616 application somehow.)

3624
3625 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3626 all of Guile basics fits into one segment and there suitable room
3627 for work.
3628 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3629 instead of 2.
3630 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.

3643 rewrite of handling of real and complex numbers.
3644 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3645 removed along with the support for floats. (Float vectors are
3646 still supported.)

3681 The following changes implement primitive support for double cells
3682 (i.e. four-word cells) and change the representation of some
3683 things to multi-cells instead of cons+malloc. (Applied and
3684 modified by mdj.)
3685
3686 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3687 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3688 multi-cell access macros (used by the ones below).
3689 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3690 macros.
3691
3692 * gc.c (scm_freelist2): multi-cell freelists.
3693 (inner_map_free_list): map_free_list, parameterized on ncells.
3694 "nn cells in segment mm" was misleading for ncells > 1; changed to
3695 "objects". still print cells too, though.
3696 (scm_map_free_list): rewritten using inner_map_free_list.
3697 (scm_check_freelist): get freelist as parameter, since now we have
3698 more than one.
3699 (scm_debug_newcell2): multi-cell variants of
3700 scm_debug_newcell.
3701 (scm_gc_for_newcell): take ncells and freelist pointer as
3702 parameters.
3703 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3704 now double cells).
3705 (scm_gc_sweep): don't free the float data, since it's not malloced
3706 anymore.
3707 (init_heap_seg): didn't understand what n_new_objects stood for,
3708 so changed to n_new_cells.
3709 (make_initial_segment): new function, makes an initial segment
3710 according to given ncells.
3711 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3712
3713 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3714 {DEFER,ALLOW}_INTS thing removed.
3715
3716 * numbers.h (struct scm_dbl): changed to represent a double cell,
3717 with the number in the second half.
16d35552
MD		 3718
3719 * dynwind.c: changed the wind-guards representation to double
3720 cell.
3721
3722 * procs.c, procs.h: changed the procedure-with-setter representation
3723 to double cell.
3724
3725 * async.c, async.h: made async representation a double cell.

3731 * ports.c (flush_void_port): renamed to flush_port_default.
3732 (end_input_void_port): renamed to end_input_default.
3733
3734 * init.c (scm_standard_stream_to_port): create a void port instead
3735 of opening /dev/null if the standard file descriptors are bad.
3736 advantages: no portability problems, doesn't waste a file descriptor,
3737 simplifies the code (thanks to Marius for the idea).
3738
3739 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3740
3741 * void ports: make reading from a void port give EOF instead of
3742 segv:
3743 * ports.c (s_scm_sys_make_void_port): modified docstring.
3744 (fill_input_void_port): new proc.
3745 (scm_init_ports): set up fill_input_void_port.
3746 * ports.c (scm_port_non_buffer): new proc.
3747 (scm_void_port): call scm_port_non_buffer.
3748
3749 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3750 which was incorrectly appended.

3754 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3755 that we can't use autoconf for this. Autoconf itself relies on
26fba922 3756 the existence of `sed' somewhere on your path.) (Thanks to Dirk

3785 the fdes is valid before doing anything else. check that
3786 the file descriptor supports the modes required.
3787 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3788 work: just use the default buffer size.
3789
3790 * throw.c: change an outdated comment about scm_internal_catch
3791 BODY: it doesn't take a jumpbuf arg.
3792
3793 * init.c (scm_standard_stream_to_port): install a handler in case
3794 scm_fdes_to_port throws an error. don't check here whether the
3795 file descriptor is valid, since scm_fdes_to_port will do that.
3796 set the revealed count depending on whether the port got the
3797 standard file descriptor.

3799 (stream_body, stream_handler): new procs.

3840 number of descriptors but the number of the highest descriptor +
3841 1.
3842
3843 This is a preliminary attempt at a cleanup of the threads support
3844 code. It moves things to better places, makes arguments more
3845 consistent with the POSIX API (which is used in GNOME's glib), and
3846 adds new functionality.

3858 functions. The strange names are temporary. Use scm_mutex_init
3859 and scm_cond_init instead.
3860 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3861 is ANSI C, but should we check for individual error codes in
3862 configure.in?
3863 (coop_condition_variable_timed_wait_mutex): New function.

3888 logical functions from SCM.

3912 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious

4037
4038 * strings.h: don't use SCM_P. don't include <string.h>.
4039 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
a00c95d9 4040
bd9e24b3
GH		 4041 * strings.c (scm_string_ref): make the 2nd argument compulsory.
4042 previously it defaulted to zero for no good reason that I can see.
4043 use a local variable for SCM_INUM (k). replace
4044 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
4045
4046 (scm_makfromstr): cosmetic changes.
4047
4048 (scm_string): Accept only chars in the list, not strings, for
4049 conformance to R5RS (particularly for list->string, which is
4050 supposed to be the inverse of string->list.) remove
4051 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
4052 scm_makstr handles the cell allocation. when reporting wrong-type
4053 arg, don't report the position as 1.
4054
4055 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.

28d77376
GH		 4061 * filesys.c (scm_select, retrieve_select_type, get_element,
4062 fill_select_type, set_element): modified so that Scheme
4063 "select" tests port buffers for the ability to provide input
4064 or accept output. Previously only the underlying file descriptors
4065 were checked. Rewrote the docstring.

4073
4074 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
4075 adding "x" prefix to the line so that guile-func-name-check
4076 doesn't complain unnecessarily.

4087
a00c95d9 4088 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
a28eb127
GB		 4089 suggests removing tag.c altogether (and using a new `class-of'
4090 instead).
4091
4092 * strings.c: Added documentation from Gregg A. Reynolds. Edited
4093 a bit by me to use FOO instead of @var{foo} and to have the
a00c95d9 4094 summary come before preconditions on input. Also dropped trailing
a28eb127
GB		 4095 (rnrs) note.
4096
4097 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
4098 function with scm_make_subr_opt w/ last arg of 0 so it is not
4099 visible at the Scheme level. Mikael says that this is the right
4100 thing because the first arg to the proc is the guts of a compiled
4101 closure and shouldn't be exposed to the Scheme level.

4148 result of scm_list_p as C boolean.
4149 (scm_display_error_message, scm_set_print_params_x): Use new

GB		 4182Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
4183
4184 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
4185 SCM_VALIDATE_LONG_COPY
4186
4187 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
4188 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
4189 couple of formal arguments (and fix their uses) to make arguments
4190 match the documentation.

MS		 41922000-01-14 <mstachow@alum.mit.edu>

GB		 4197Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
4198
4199 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
4200 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
4201
59d5245f
GB		 4202Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4203
4204 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
4205 the way guile-1.3.4 worked, but #if 0 out the version using
4206 SCM_VALIDATE_INUM_COPY for stricter testing.

GB		 4208Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
4209
4210 * guile-doc-snarf.in: Use new $fullfilename for running
4211 guile-func-name-check, and put "$fullfilename" and "$filename" in
4212 quotes at uses to make sure re-splitting on whitespace does not
a00c95d9 4213 occur (so filenames w/ embedded whitespace would work okay, though
95aec69f
GB		 4214 I sure hope we never have to deal with that! :-) ). Thanks to
4215 Mikael for pointing out the source_dir != build_dir was broken.

GB		 4217Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
4218
4219 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
4220 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
4221 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
4222 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
4223 variants.
4224
4225 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
4226 then return whether it's an open port (was validating that it was
4227 an open port -- this was a bug I introduced back in December, but
4228 my careful reading of diffs caught it).
4229
4230 * numbers.c: Recombine the two conditional-compilation paths for
4231 all the log* primitives -- they were split based on #ifndef
4232 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
4233 some bugs and inconsistencies in the two sets of implementations.
4234 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
4235
4236 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
4237 SCM_VALIDATE_INUM_COPY once where it should've been used.
4238
4239 * fluids.c (scm_internal_with_fluids): Use
4240 SCM_VALIDATE_LIST_COPYLEN.
4241
4242 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
4243 this is questionable as it relaxes type safety, but other changes
4244 were useful and all SCM_NUM2LONG's should probably be
4245 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
4246
4247 * evalext.c: line-break change on 1 line.
4248
4249 * eval.c (nconc2last): Takes a non-empty list as its first
4250 argument, not just a list.
4251
4252 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
4253
4254Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
4255
4256 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
4257 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
4258 where possible.
4259
4260 * symbols.c (scm_sysintern0): Fixed the function name in a
4261 scm_misc_error invocation.
4262
4263 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
4264 use scm_return_first to ward off latent GC bug that Mikael caught.
4265
4266 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
4267 used before but should've been.

4275
4276 * guile-func-name-check.in: Added this script to statically check
4277 #define FUNC_NAME, #undef FUNC_NAME in the source.
4278
4279 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
4280 redundant comment, semicolon; caught by new guile-func-name-check
4281 script.
4282
4283 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
4284 Caught by new guile-func-name-check-script.
4285
4286 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
4287
4288 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
4289 guile-func-name-check.
4290
a00c95d9 4291 * guile-doc-snarf.in: Run guile-func-name-check on the file before

4300
4301 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
4302 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
4303 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
4304 consistency with the other macros dealing with immediate
4305 characters. (Similar to INT -> INUM change a week or so ago).

4309 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
4310 net_db.c, read.c, socket.c: Update error messages to use ~A for
4311 %s, ~S for %S to work with new `simple-format' format and be
4312 standardized better.
4313
4314 * print.h, print.c (scm_simple_format): Added `simple-format'
4315 primitive. It's the old scm_display_error, with ARGS now a rest
a00c95d9 4316 parameter, and the destination first instead of last (and a couple
7965d98f
GB		 4317 new capabilities inspired by `format' -- #t as destination means
4318 current-output-port, #f means return the formatted text as a
4319 string.
4320
4321 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
4322
4323 * backtrace.c (scm_display_error_message): Rewrote to use
4324 scm_simple_format() procedure.
4325
4326 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST

4330 Finally applied the libltdl patch from Thomas Tanner, with slight
4331 modifications.
4332
4333 * DYNAMIC-LINKING: Removed because it is obsolete.
4334 * dynl.c: Use ANSI prototypes.
4335 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
4336 * scmconfig.h.in: Do not change, as it is automatically generated.

4343 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
4344 against libltdl
4345 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,

4351 * These changes should make it unnecessary to call tzset from
4352 Scheme after modifying the TZ environment variable, even if the
4353 system date facilities cache the value.
4354 * stime.c (setzone, scm_localtime): added comments.
4355 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
4356 (setzone): don't call tzset.
4357 (restorezone): call tzset only if HAVE_TZSET is defined.

4399
4400 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4401 report the position of the argument.
4402
a00c95d9 4403 * error.h, error.c (scm_out_of_range_pos): Added this function to

4407 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4408
4409 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
4410 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael

4414
4415 * snarf.h: Factor out differences between C++ and non-C++ into
4416 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
4417 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
4418 Mikael's macros, below, but changed names and SCM_SNARFING no
4419 longer expands to include %%% -- that must appear in the argument
4420 so that the token appears at the call-site as a reminder).

4425 snarf macro definitions.

4429 * chars.c (scm_integer_to_char): Use Greg's nice
4430 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
4431 adherence to R5RS.

2cc0f8cb

4446 macro call.

4449
4450 * scm_validate.h: Remove some redundant NIMP tests.
4451
4452 * alist.c: minimize scope of the tmp variables, and initialize
4453 them when declared. The strange SCM_NIMP tests are replaced by
4454 SCM_CONSP tests that more closely reflect the intended semantics.
4455 However, we don't get a performance penalty here, because the
4456 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
4457 extremely ugly use of ASRTGO macros was removed: The calls to
4458 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
4459 label parameter that only exists when SCM_RECKLESS is not defined.
4460 This works, because ASRTGO itself is defined in a way that it only
4461 makes use of the label parameter if SCM_RECKLESS is not defined
4462 (shudder!). Does guile make at all use of the possibility to
4463 define SCM_RECKLESS? * Codesize is likely to be reduced, since
4464 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
4465 we now only get one test.
4466
4467 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
4468 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
4469 some variables in `list?'. Fix `reverse' and `reverse!'
4470 primitives to handle improper lists better.

4475 macros and SCM_DEFINE macros to match GNU coding standards.

4484 better consistency with the names of other SCM_VALIDATE_ macros

4488
4489 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4490 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4491 it's not the actual name of the formal).

4493 * guile-snarf.awk.in: Do argument/number mismatch checking and
4494 print warnings in an Emacs compile-mode parseable format.
4495
4496 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4497 SCM_OUTOFRANGE as 3rd argument.
4498
4499 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4500
4501 * __scm.h: Do not #define SCM_ARG* when snarfing;
4502 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4503 the former (using the number) requires the argument to match the
4504 formal in the current argument snarfing check.
4505
4506 * snarf.h: Give new definition of SCM_ASSERT when in
a00c95d9 4507 snarfing mode to output a lexically-identifiable sequence that the
1e484823
GB		 4508 guile-snarf.awk script uses to verify argument/position matching.
4509
4510 * ramap.c: Remove extraneous #undef FUNC_NAME.

4513
4514 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
a00c95d9 4515 current version of the same functionality; it writes the .x output
53fc4636
GB		 4516 to stdout instead of directly into the file.

4520 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4521 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4522 redundant with the safer macros. Patch from Dirk Hermann applied
4523 by hand. Thanks Dirk!
4524
4525 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4526 uses in random.c.

4533 removals from Dirk Hermann.
4534
4535 * alist.c: Rename formals to match the parameter names in the
4536 documentation, updates to documentation. Thanks Dirk Hermann!
