4 Thanks to Bill Schottstaedt.
6 2001-01-11 Michael Livshin <mlivshin@bigfoot.com>
10 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
11 casts its result, so doesn't yield an lvalue per ANSI C.
13 * goops.c (s_scm_sys_set_object_setter_x): use
14 SCM_SET_ENTITY_SETTER.
15 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
17 * gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts

20 (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
21 SCM_GC_SET_CARD_FLAGS.

28 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
29 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
30 socket.c (scm_recvfrom): use the new macro, plus minor docstring
32 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
33 for fdes. if current input port is used, check that it's a file
36 2001-01-06 Gary Houston <ghouston@arglist.com>

48 2001-01-03 Michael Livshin <mlivshin@bigfoot.com>
50 * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
51 SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
52 SET_DESTROYED): new defines/macros.
53 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
54 (add_to_live_list): takes a `guardian_t *' now, not SCM.
55 (guardian_print): print more info.
56 (guardian_apply): check if the guardian is destroyed, and throw an
57 error if so. take one more optional argument `throw_p'.
58 (scm_guard): depending on the value of `throw_p', return a boolean
60 (scm_get_one_zombie): remove redundant property test.
61 (guardian_t): represent the various (currently 3, I hope nothing
62 more gets added) boolean fields as bit flags.
63 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
64 (scm_destroy_guardian_x): new procedure.
66 * guardians.h: added prototypes for `scm_guardian_greedy_p' and
67 `scm_guardian_destroyed_p'. changed prototype for `scm_guard'.
69 2001-01-01 Gary Houston <ghouston@arglist.com>
71 * fports.c (fport_write): bugfix: handle short writes for
72 unbuffered ports too. optimize the buffered case by minimizing
73 the number of write/flush calls.
74 (write_all): new helper procedure.
76 2000-12-30 Michael Livshin <mlivshin@bigfoot.com>
78 * guardians.c (guardian_print): for sharing guardians, print that
80 (scm_guard, scm_get_one_zombie): place the critical section
81 barriers more correctly.
83 * weaks.c (scm_scan_weak_vectors): move the calculation of the
84 `weak_keys' and `weak_values' flags out of the inner loop.
86 2000-12-29 Michael Livshin <mlivshin@bigfoot.com>
88 * guardians.c: (greedily_guarded_prop): deleted.
89 (greedily_guarded_whash): new variable. a doubly-weak hash table
90 used to keep the "greedily guarded" object property. the previous
91 implementation (via primitive object properties) was incorrect due
92 to its only-the-key-is-weak semantics.
93 (scm_guard, get_one_zombie, scm_init_guardians): use/init
94 `greedily_guarded_whash'.
96 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
98 * eval.c (check_map_args), gh_data.c (gh_set_substr,
99 gh_scm2newstr, gh_get_substr, gh_symbol2newstr), print.c
100 (scm_iprin1): Use scm_remember_upto_here_1 instead of

106 (scm_remember): Deprecated.
108 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
110 * continuations.c (scm_make_continuation): Make variable cont
111 volatile to let the compiler know that it won't be clobbered by
112 longjmp. (It wouldn't be anyway, but for some reason the compiler
113 is not able to see that.)
115 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
117 This patch re-introduces the unused member "properties" of
118 struct scm_subr_entry as requested by Mikael Djurfeldt.
120 * procs.h (scm_subr_entry): Re-introduced member "properties".
122 (SCM_SUBR_PROPS): Un-deprecated.
124 * procs.c (scm_make_subr_opt, scm_mark_subr_table): Struct
125 scm_subr_entry has a member "properties" again.
127 2000-12-28 Michael Livshin <mlivshin@bigfoot.com>
129 * guardians.c (mark_dependencies_in_tconc): new function.
130 (mark_dependencies): bug fix. mark the dependencies of the known
133 2000-12-24 Michael Livshin <mlivshin@bigfoot.com>
135 * gc.c: (scm_gc_mark_dependencies): use SCM_EQ_P for SCMs, not
136 '=='. also, return after calling `scm_gc_mark'.
138 2000-12-24 Michael Livshin <mlivshin@bigfoot.com>
140 * gc.c: (scm_gc_mark_dependencies): new function. like
141 `scm_gc_mark', but doesn't mark the argument itself. defined
142 using an arrangement similar to that in eval.c: `scm_gc_mark' and
143 `scm_gc_mark_dependencies' are derived from the same "template"
144 by ugly preprocessor magic.
146 * gc.h: added prototype for `scm_gc_mark_dependencies'.
148 * init.c (scm_init_guile_1): call the renamed
149 `scm_init_guardians'.
151 * guardians.h: changed prototypes for `scm_make_guardian' and
152 `scm_init_guardians'.
154 * guardians.c (guardian_t): added new fields `greedy_p' and
156 (GUARDIAN_P): predicate that says whether its argument is a
158 (GUARDIAN_GREEDY_P, GUARDIAN_LISTED_P): new predicates.
159 (greedy_guardians, sharing_guardians): new variables. hold the
160 greedy and sharing live guardian lists, respectively.
161 (first_live_guardian, current_link_field): removed.
162 (greedily_guarded_prop): new variable. holds the "is greedily
163 guarded" object property.
164 (self_centered_zombies): new variable. stores guarded objects
165 that are parts of cycles.
166 (add_to_live_list): new function, introduced to decouple marking a
167 guardian and adding it to the live list.
168 (guardian_mark): call `add_to_live_list'.
169 (guardian_print): print whether the guardian is greedy or not.
170 also change "live" and "zombie" to "reachable" and "unreachable"
171 respectively, to be less confusing.
172 (scm_guard): if the guardian is greedy, test whether the object is
173 already greedily marked. throw an error if so.
174 (scm_get_one_zombie): if the guardian is greedy, remove the
175 "greedily guarded" property from the object.
176 (scm_make_guardian): add a new optional boolean argument which
177 says whether the guardian is greedy or sharing.
178 (guardian_gc_init): init the new live lists.
179 (mark_dependencies): new function.
180 (mark_and_zombify): new function.
181 (guardian_zombify): reworked to support the new guardian
182 semantics. move some logic to `mark_dependencies' and
184 (whine_about_self_centered_zombies): new function. installed in
185 the `after-gc-hook' to complain about guarded objects which are
187 (scm_init_guardians): init the new stuff. renamed from
190 2000-12-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
192 * procs.h (scm_subr_entry): Removed unused struct member
195 (SCM_SUBR_PROPS): Deprecated.
197 * procs.c (scm_make_subr_opt, scm_mark_subr_table): Struct
198 scm_subr_entry does not have a member "properties" any more.
200 2000-12-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
202 * procs.h (scm_subr_entry): Removed unused struct member
205 (SCM_SUBR_DOC): Deprecated.
207 * procs.c (scm_make_subr_opt): Eliminate use of scm_intern0 in
208 favor of scm_str2symbol. Similarly, prefer scm_sysintern over
211 (scm_make_subr_opt, scm_mark_subr_table): Struct scm_subr_entry
212 does not have a member "documentation" any more.
214 2000-12-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
216 * eval.c (restore_environment): Make sure that changes to the
217 current environment will take effect when re-entering the dynamic

227 2000-12-20 Gary Houston <ghouston@arglist.com>
229 * continuations.c (continuation_apply): subtract the length of
230 continuation->dynenv, not the dynenv itself. I broke it last
231 time I changed this file. thanks to Bernard Urban.
233 2000-12-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
235 * goops.c (remove_duplicate_slots, maplist,
236 scm_sys_initialize_object, scm_sys_prep_layout_x,

312 renamed to symbols. The initialization of the symbols hash table
313 is done in function scm_symbols_prehistory.
315 * gc.c (scm_init_storage): Don't initialize scm_symbols. Don't
316 define most-positive-fixnum, most-negative-fixnum and

341 (scm_str2symbol): Rewritten in terms of scm_mem2symbol.
343 (scm_sym2vcell): For system bindings, there is now only one
344 obarray - scm_symhash. If scm_sym2vcell is called to look up a
345 symbol that can't be found and shall not be created, #f is
346 returned. Most callers of scm_sym2vcell have expected this
349 (scm_intern_obarray_soft): Removed reference to scm_weak_symhash
352 (scm_intern_obarray_soft, scm_sysintern0_no_module_lookup): These

966 guile-doc-snarf. it doesn't seem to do anything useful, but would
967 fail if $PATH contained whitespace. Thanks to Lars J. Aas.

993 * fports.c: include gc.h.
994 (fport_flush, fport_close): silently ignore I/O errors when

1011 * ports.c (scm_port_for_each): new proc. implements port-for-each,
1012 which applies a procedure to each port in the port table.
1013 ports.h: declare scm_port_for_each.
1015 * ioext.c (scm_dup2): new proc. implements "dup2" which is a simple

1030 scm_si_n_specialized from fixnum and don't take absolute value.

1033 2000-11-04 Gary Houston <ghouston@arglist.com>
1035 * ports.c (scm_port_p): new function, implements "port?" which
1036 is mentioned in R5RS.

1041 * backtrace.c (display_expression, display_error_body), fports.c
1042 (prinfport), print.c (scm_iprin1): Test for symbols and strings
1043 explicitly instead of using SCM_ROSTRINGP.
1045 * backtrace.c (scm_display_error_message): Don't pass a symbol to
1046 scm_simple_format. Prefer high-level output functions.
1048 (display_error_body): When displaying procedure names, give
1049 preference to the name passed as a parameter. Only if none is
1050 given extract a name from the stack information.

1091 * unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
1092 allow vectors longer than SCM_LENGTH_MAX. This removes the
1093 SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
1094 SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
1095 all of guile's code was implemented to be aware of this trick, it
1096 is unlikely that it was used anyway. We can implement such a
1097 feature more cleanly by using double cells for uniform vector
1100 (scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
1101 straightforward predicates.
1103 (scm_dimensions_to_uniform_array): Require that for dimensions
1104 given as lower-bound/upper-bound pairs the upper-bound is never

1149 (scm_convert_exec_args): Aligned to match each other.
1151 * dynl.c (scm_coerce_rostring): Removed.
1153 (scm_dynamic_func): Changed the comment to reflect that the
1154 function name has to be a string. Further, hide implementation
1155 details from the scheme comment.
1157 * error (scm_error_scm): Don't accept a symbol as message
1158 parameter. Fix substring handling.
1160 * posix.c (environ_list_to_c): Use memcpy to copy environment
1161 strings. Handle substrings which don't have a trailing \0.

1176 * strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
1177 intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
1178 will be necessary, even after copy-on-write strings will be added
1179 to guile, but the current naming is inappropriate.
1181 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
1182 scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as

1184 are rewritten to compare from back to front, the others are also a
1185 little bit more polished.
1187 2000-10-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1189 This change merges the GOOPS code into Guile. However, GOOPS
1190 is still not initialized until someone asks for the module.
1191 We need to optimize GOOPS initialization time before initializing
1192 it together with the rest of libguile. We also need to add the
1193 C API + primitive methods. Then we can start using it to
1194 modularize Guile, implement a real exception system etc.

1248 symbols.h (SCM_COERCE_SUBSTR): Use SCM_STRING_LENGTH instead of

1702 This patch unifies the formerly distinct ssymbol and msymbol types
1703 to a common symbol type scm_tc7_symbol. The representation of the
1704 new symbol type uses a double cell with the following layout:
1705 <type/length, chars, raw_hash, prop-pair>, where the car of
1706 prop-pair holds the symbol's function property and the cdr of
1707 prop-pair holds the symbol's other properties. In the long run,

1709 functions will be uses.

1725 is not used any more.
1727 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
1729 (scm_intern_obarray_soft): Made softness parameter unsigned.
1731 (scm_string_hash): New function with the same functionality as
1732 scm_strhash had before, except that the hash value is not adjusted
1733 to a hash table size. Instead, the 'raw' hash value is returned.
1735 * symbols.c (duplicate_string): New static convenience function.
1737 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):

1867 on the user establishing a catch-all, which might be difficult for
1868 him if he is using scm_init_guile instead of scm_boot_guile.

1902 (scm_array_map_x): Docstring: add @deffnx line for
1903 array-map-in-order!.
1905 * posix.c (scm_mknod): Docstring format fix: missing newlines
1908 * modules.c (scm_interaction_environment): Docstring fix: add
1911 * eval.c (scm_cons_source): Added newly written docstring.
1913 2000-09-03 Michael Livshin <mlivshin@bigfoot.com>
1915 the following changes let Guile get rid of the `allocated' cell
1918 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
1921 * tags.h (scm_tc16_allocated): removed.
1923 * gc.h: removed now-obsolete comments about the `allocated' cell
1925 (SCM_NEWCELL): don't change cell type to `allocated'.
1926 (SCM_NEWCELL2): ditto.
1928 * gc.c (scm_mark_locations): mark freecells too, and don't worry
1929 about any possible false positives.
1930 (scm_debug_newcell): don't change cell type to `allocated'.
1931 (scm_debug_newcell2): ditto.
1932 (scm_gc_for_newcell): ditto.
1933 (scm_gc_mark): remove the tc16_allocated case.
1935 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1937 * gdbint.c (gdb_print): Removed superfluous macro definition.
1939 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
1940 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
1941 string, not a symbol. (`make-vtable-vtable' needs to append this
1942 string to another string and then pass it through
1943 `make-struct-layout'.)
1945 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
1946 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
1948 * struct.c (scm_make_struct_layout): Removed reference to
1949 "read-only string" in comment; Check that argument is a string.
1950 (scm_make_vtable_vtable): Check that argument is a string.
1952 * environments.c (scm_init_environments): All internal includes in
1953 libguile must use the prefix "libguile/" in path names since inly
1954 the top-level source directory is on the include list. (That, in
1955 turn, is because we want to distinguish between system header
1956 files and hedares files internal to libguile.)
1958 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
1960 (scm_string_length, scm_string_ref, scm_substring,
1961 scm_string_append): Don't accept symbols as arguments (R5RS).
1963 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
1965 * ports.c (scm_set_port_column_x): Fix docstring so that it
1966 mentions set-port-line! rather than set-port-column! twice.
1968 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
1970 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1972 * Makefile.am: Added all necessary environments.* files.
1974 * init.c: Include environments.h.
1976 (scm_boot_guile_1): Initialize the environments.
1978 * environments.[ch]: Added. Most of the credit for these files
1979 goes to Jost Boekemeier.
1981 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1983 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
1985 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
1987 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
1988 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
1989 (scm_set_smob_apply): New function.
1990 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
1991 scm_smob_apply_3): New functions.
1992 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
1993 * procs.c (scm_procedure_p): Check applicable smobs.
1995 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1997 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
1998 also here. (This is supposed to make sure that scmconfig.h is
1999 built before all sources in order to prevent that everything has
2000 to be rebuilt again. Hope it works---I'm just guessing. :)
2002 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
2004 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2006 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
2007 extra tests. (GUILE_DEBUG is only supposed to make extra
2008 debugging functions available.)
2010 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
2012 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
2015 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
2017 * gc.c (scm_gc_sweep): added a `continue' statement that have
2018 fallen through the cracks in the merge. thanks to Shuji Narazaki!
2020 * gc.h: removed some stuff that broke compilation for people and
2021 wasn't actually needed anyway.
2023 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
2025 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
2027 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
2028 scm_setnet, setproto, setserv): Argument names changed to match
2031 * feature.c (scm_program_arguments): New docstring.
2033 * simpos.c (scm_getenv): Reflow docstring.
2035 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
2038 * chars.c (scm_char*): Docstring fixes - texinfo markup.
2040 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
2042 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
2043 texinfo markup and remove trailing newlines.
2045 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
2047 this changes the Guile GC to use cards (aka "chunklets").
2048 (most of the ideas and some of the code are by Greg Harvey, though
2049 the code is probably unrecognizable now. the original chunklet
2050 proposal, way back, is by Dale Jordan).
2052 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
2053 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
2054 some (most) of these are probably going to be deprecated.
2056 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
2058 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
2059 cards and bvecs (bit-vectors).
2061 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
2062 account, but keeping more or less the same values as previously.
2063 added some simple helper macros.
2064 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
2066 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
2067 current_mark_space_offset, mark_space_head, get_bvec,
2068 clear_mark_space): new functions and supporting variables, types
2069 and macros that implement mark space management.
2070 (scm_igc): clear the mark space (all of it) before beginning the
2072 (scm_gc_mark): changed the tests for rogue cells, much simplified
2073 throughout (no different mark bit locations to worry about now).
2074 (scm_mark_locations): don't consider card header cells.
2076 (scm_gc_sweep): simplified.
2077 (init_heap_seg): changed to take cards into account.
2079 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
2081 * stime.c (scm_c_get_internal_run_time): new function, same as
2082 scm_get_internal_run_time but returns a long. it's used by the GC
2083 for timekeeping, since with scm_get_internal_run_time there is a
2084 (extremely theoretical) possibility of consing.
2085 (scm_get_internal_run_time): redefined in terms of
2086 scm_c_get_internal_run_time.
2088 * stime.h: added prototype for scm_c_get_internal_run_time.
2090 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
2091 sweep time, total marked cells, total swept cells, and number of
2092 times GC was invoked.
2093 (gc_start_stats): renamed from scm_gc_start, made static, taught
2094 to init the new stats.
2095 (gc_end_stats): renamed from scm_gc_end, made static, taught to
2096 calculate the new stats.
2097 (scm_igc): don't call gc_start_stats unless we are sure that we
2098 are indeed going to collect. also, added some timekeeping between
2099 the mark and sweep phases.
2100 (scm_gc_sweep): count number of cells we sweep as we go.
2102 * gc.h: removed prototypes for scm_gc_{start,end}.
2104 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2106 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
2107 error for the alist rather than the sublist where the type
2108 mismatch is discovered.
2110 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
2112 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

2135 * list.c (scm_list_tail): Add @deffnx line to docstring for
2138 * keywords.c: Docstring improvements in conjunction with new
2139 reference manual doc on keywords.
2141 * error.c (scm_error_scm): Fix texinfo syntax error in
2142 docstring. (@code(~S) should be @code{~S}.)
2144 * dynl.c: Remove surplus newlines from end of docstrings.
2146 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2148 * eval.c (scm_eval): Backward incompatible change: Now takes an
2149 environment specifier as second arg. `eval' hereby becomes R5RS
2151 (scm_i_eval_x, scm_i_eval): New functions (replace
2153 (scm_eval2, scm_eval_3): Deprecated.
2154 (scm_top_level_lookup_closure_var): Deprecated.
2156 * eval.h: #include "struct.h".
2158 * evalext.c (scm_definedp): Have to work before module system is
2161 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,
2162 SCM_MODULE_OBARRAY, SCM_MODULE_USES, SCM_MODULE_BINDER,
2163 SCM_MODULE_EVAL_CLOSURE): New macros.
2164 (scm_module_index_obarray, scm_module_index_uses,

2182 * load.c (load): Use `scm_selected_module' to compute second arg
2183 to new scm_i_eval_x; Don't call it if module system hasn't booted.
2184 (scm_read_and_eval_x): Deprecated.
2185 #include "modules.h".
2187 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
2188 (scm_start_stack): Use scm_i_eval.
2190 * strports.c: #include "modules.h".

2195 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2197 The following changes are intended to ensure that struct instances
2198 are freed before their vtables. It's optimized for the most
2199 common case, which is freeing of struct instances.
2201 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
2202 (scm_structs_to_free): New variable.
2203 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
2206 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
2208 (scm_structs_to_free, scm_struct_prehistory): Declare.
2210 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
2211 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
2213 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
2214 (scm_struct_prehistory): Install them.
2216 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
2218 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
2220 * read.c (scm_flush_ws): Include filename in error message when it
2223 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
2225 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
2227 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2229 * struct.c (scm_make_struct_layout, scm_make_struct,
2230 scm_make_vtable_vtable): Updated documentation.
2232 * print.c (scm_simple_format): Bugfix: Coerce port before using
2235 2000-07-31 Gary Houston <ghouston@arglist.com>
2237 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
2238 (thanks to Richard Kim for the bug report).
2240 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
2242 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2243 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
2244 using the latter is pointless.
2246 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2248 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
2249 'free_struct_data' to avoid confusion with stdlib's 'free'.
2251 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2253 * vectors.c (scm_make_vector): Fix the initialization order of
2254 the vector such that the type cell is initialized last.
2256 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2258 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
2259 on the struct cell to be fully initialized.
2261 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
2262 initialization order of the struct such that the type cell is
2265 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
2267 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2268 scm_assoc_remove_x): Remove only the first cell with a matching
2271 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
2273 * stime.c (scm_strftime): Recognize a return value of zero from
2274 strftime as buffer overflow and take care to detect a valid zero
2275 length result regardless. Thanks to David Barts!
2277 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
2279 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
2280 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
2281 equal (respectively) to the argument key, not all cells that are
2282 eq, eqv, or equal to the first cell with the argument key. Thanks
2285 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2287 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
2288 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
2289 SCM values appropriately.
2291 * modules.c (scm_standard_eval_closure): Don't pass an inum to
2292 scm_makcclo, but rather a long value.
2294 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2296 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
2297 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
2298 Thanks to Han-Wen Nienhuys for the bug report.
2300 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2302 * root.[ch] (scm_call_catching_errors): Deprecated.
2304 * root.c (scm_init_root): Initialize the root smob type using the
2305 standard initialization functions.
2307 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
2309 * eval.c (unmemocopy): Don't rely on V being a list of at least
2310 one element. Thanks to Bill Schottstaedt!
2312 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
2314 * gc.c (scm_done_free): new.
2315 expanded comments about scm_done_malloc.
2317 * gc.h: added prototype for scm_done_free
2319 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
2321 * gc.h (scm_take_stdin): Removed.
2323 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
2324 scm_assert_cell_valid to allow extensions to the checking
2325 functionality without need to recompile everything.
2327 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
2328 Added as conditionally compiled functions for the case that
2329 SCM_DEBUG_CELL_ACCESSES is enabled.
2331 * gc.c (debug_cells_p): Added to indicate whether compile-time
2332 included cell access debugging is run-time enabled.
2334 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
2335 being executed. Intended to be used instead of scm_gc_heap_lock
2338 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
2339 instead of scm_gc_heap_lock.
2341 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
2343 * gc.c (scm_mark_locations): Don't mark free cells.
2345 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
2348 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
2350 * gc.c (scm_mark_locations): Minimized some variable scopes and
2351 simplified the code a bit.
2353 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2355 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
2356 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
2357 should not be accessed via SCM_C[AD]R. Further, using dedicated
2358 macros to access free cells allows all other cell accessing macros
2359 to treat acesses to free cells as errors, thus enabling better
2360 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
2361 replace SCM_FREEP some time.
2363 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
2364 free_list_length, scm_check_freelist, scm_debug_newcell,
2365 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
2366 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
2367 cell accessors when accessing free cells.
2369 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2371 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
2372 object as const in order to make the compiler warn about code like
2373 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
2376 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
2377 as an address to a non-const object, since these macros are used
2378 to allow direct write access to objects.
2380 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
2382 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
2383 given hash table has no slots.
2385 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2387 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
2388 to react to malloc failures in a context dependent way.
2390 (scm_check_freelist): No need to flush streams before abort().
2392 (scm_gc_for_newcell): Try to allocate new memory in three phases:
2393 grow heap if preferred, if still no memory available collect
2394 garbage, if still no memory available grow heap.
2396 (heap_segment_table_size): Added to always reflect the actual
2397 size of the heap segment table, because scm_n_heap_segs may differ
2398 from the heap segment table size.
2400 (alloc_some_heap): In case of malloc failure, react according to
2401 the new policy_on_error parameter (either return to caller or
2402 abort immediately). Further, keep heap_segment_table_size up to
2405 (scm_init_storage): Initialize heap_segment_table_size.
2407 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2409 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
2412 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2414 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
2415 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
2416 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
2417 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
2420 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
2421 and SCM_NALLOC, but as a deprecated feature.
2423 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2425 * debug.c: Added #include fluids.h.
2427 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
2428 primitive generics. (Thanks to Nicolas Neuss.)
2430 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2432 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
2433 failed attempt to get additional memory from the system.
2435 (scm_gc_for_newcell): Changed the control structure to make the
2436 behaviour explicit for the case that gc is not able to free any
2439 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2441 * __scm.h (SCM_OUTOFRANGE): Removed.
2443 * error.c (scm_wta): Removed sick dispatch code for range
2444 errors. (More sick dispatches still to be removed.)
2446 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2447 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
2448 value is non-negative. Use scm_out_of_range to signal range
2451 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
2452 signal range errors.
2454 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
2455 error reporting (now uses original input parameter to report wrong
2456 type argument errors). Use SCM_OUT_OF_RANGE to report range
2457 errors and SCM_WRONG_TYPE_ARG to report type errors.
2459 * strings.c (scm_substring): Make range checks for negative
2460 values explicit (former behaviour relied on an implicit
2461 conversion from signed to unsigned). Don't use SCM_ASSERT for
2464 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
2465 scm_bit_count_star): Use scm_out_of_range to signal range
2468 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
2469 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
2470 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
2472 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2474 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
2475 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
2476 Perform all range checks based on the input value. The former way
2477 of using the value that is assigned to the target variable fails
2478 if the assignment to the target variable itself can change the
2479 value because of type conversion.
2481 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
2483 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2485 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
2486 doesn't yield any new cells. In theory this could happen if all
2487 cells allocated with NEWCELL are either in use or conservatively
2488 marked and all cluster spine cells are conservatively marked.
2491 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2493 * __scm.h (SCM_NALLOC): Removed.
2495 * error.c (scm_wta): Removed sick dispatch code for memory
2496 errors. (More sick dispatches still to be removed.)
2498 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
2499 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
2500 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
2501 (scm_vector_set_length_x): Now using scm_memory_error to signal
2504 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2506 * __scm.h: Removed some commented code and fixed some comments.
2508 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
2509 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
2510 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
2512 * async.c: Removed some commented code.
2514 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2516 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
2517 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
2518 appropriate error signalling function.
2520 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2522 * root.h (scm_first_type): Removed.
2524 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2526 * gc.c (MIN_GC_YIELD): Removed.
2528 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
2530 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
2533 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2535 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
2538 (scm_init_async): Moved initialization for scm_gc_async and
2539 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
2542 * async.h (scm_gc_async): Not globally visible any more.
2544 * gc.c (scm_gc_stats): Made callable even from within regions
2545 where gc is blocked.
2547 (scm_gc_end): Eliminate the hardcoding of the marking of the
2548 scm_gc_async from the gc core.
2550 (scm_init_storage): Don't initialize the scm_asyncs list here.
2551 This is now done in asyncs.c.
2553 (scm_gc_vcell): Moved here from async.c.
2555 (gc_async): Renamed from scm_gc_async, moved here from async.c
2558 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
2561 (mark_gc_async): New hook function for scm_after_gc_c_hook.
2563 (scm_init_gc): Added initialization of scm_gc_vcell and
2564 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
2566 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
2569 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2571 * gc.c (scm_igc): Removed commented code that once was intended
2572 to unprotect struct types with no instances.
2574 * root.h (scm_type_obj_list): Removed.
2576 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2578 * async.c (scm_init_async): Switch to standard way of smob
2581 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
2583 * guile-doc-snarf.in: use cut instead of sed, that's much much
2584 faster. also, don't call basename more than needed. and, to gain
2585 a couple of microseconds more, don't call cat needlessly. (thanks
2588 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2590 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
2591 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
2592 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
2594 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2596 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
2597 #include "libguile/fluids.h".
2599 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
2600 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
2602 * root.h (scm_top_level_lookup_closure_var,
2603 scm_system_transformer): Removed. (It's no sense in having the
2604 *variable* be a "fluid".)
2606 * root.c (mark_root): Removed marking of
2607 s->top_level_lookup_closure_var and s->system_transformer.
2609 * modules.c (scm_selected_module): the_module is now a fluid.
2611 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2613 * gc.h, tags.h: Be kind to compilers which must see hash signs in
2614 column 0. (Thanks to Ian Grant.)
2616 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
2617 the long_long type. (Thanks to Bernard Urban.)
2619 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2621 * gc.c, gc.h (scm_default_init_heap_size_1,
2622 scm_default_min_yield_1, scm_default_init_heap_size_2,
2623 scm_default_min_yield_2, scm_default_max_segment_size): New global
2624 variables. Can be customized by the application before booting
2625 Guile. (We might want to be able to control these parameters
2626 dynamically through the "options interface" in the future, but
2627 note that that is additional functionality. Here we're giving
2628 default values which the environment variables can override.)
2630 * list.c (scm_cons_star): Updated comment.
2632 * smob.h: Changed comments for scm_make_smob_type and
2633 scm_make_smob_type_mfpe, warning that the latter might be
2634 deprecated in a future release.
2636 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2638 * list.[ch] (scm_cons_star/cons*): Renamed from
2639 scm_list_star/list*.
2641 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
2642 for scm_cons_star/cons*.
2644 * gc.c (scm_protect_object): Updated comment.
2646 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
2648 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
2650 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2652 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
2655 * gdbint.c (gdb_print): Print warning instead of calling scm_write
2656 if Guile isn't yet initialized.
2658 * print.c (scm_current_pstate, scm_make_print_state): Simplified
2659 tests, using the assumption that Guile has been initialized.
2661 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2663 * print.c (s_scm_current_pstate): Do not segfault when the
2664 print_state_pool is unitialized in `current-pstate', and better
2665 verify its state before altering it in scm_make_print_state().
2667 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
2669 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
2670 #ifdef -- it's missing on at least one platform. (thanks to
2673 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
2675 * list.c (list*): Added documentation from common-list.scm.
2677 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
2679 * gc.c (scm_unprotect_object): The reference count is guaranteed
2680 to be a positive number.
2682 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2684 * eval.c: Updated comment above scm_map.
2686 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2688 * gc.c (scm_protect_object): Avoid looking up the object handle
2690 (scm_unprotect_object): Abort if scm_unprotect_object is called on
2691 an unprotected object.
2693 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
2695 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
2698 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2700 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
2702 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
2703 Ditto for `tmp_size'.
2704 (scm_addr_buffer_size): Changed type from int to size_t.
2706 * random.c: #include <string.h>. (Needed by memcpy.)
2708 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
2709 indicating stdin, instead of "" and don't reset ARGC. This is a
2710 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
2711 it is correct, and perhaps even better.
2713 2000-06-14 Gary Houston <ghouston@arglist.com>
2715 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
2716 defined, add SA_RESTART to the sigaction flags correctly
2717 (thanks to Dale P. Smith).
2719 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2721 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
2723 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
2724 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
2726 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
2728 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2730 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
2731 since read and write buffers are allocated by `malloc'.
2733 * Makefile.am: Removed old test code.
2735 * gh_test_c.c, gh_test_repl.c: Removed.
2737 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2739 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
2742 * inet_aton.c (inet_aton): Cast init value for `cp'.
2744 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
2747 * symbols.c (scm_intern_obarray_soft,
2748 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
2749 in calls to scm_strhash.
2751 * strports.c (st_resize_port): Substituted SCM_UCHARS for
2753 (st_write): Cast argument to strncpy to char ptr.
2754 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
2755 (scm_strport_to_string): Cast argument to scm_makfromstr to char
2758 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
2759 storing in putback_buf.
2760 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
2762 * ioext.c (s_scm_read_line): Cast result of call to
2763 scm_do_read_line to unsigned char ptr.
2765 * gdbint.c (SEND_STRING): Cast argument to char pointer.
2767 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
2770 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
2771 shouldn't use Make rules which aren't supported by most Make
2773 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
2774 want these dependencies recorded, since they would get bogus
2775 relative paths; libguile.h is only used in gh.h and guile.c.)
2776 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
2777 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
2778 (modinclude_HEADERS): Removed kw.h.
2780 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
2781 (The preprocessor might insert spaces before the identifier.)
2783 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
2784 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
2786 * smob.h (scm_smobfuns): Removed deprecated type.
2788 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
2789 (Replaced by `scm_make_smob_type'.)
2791 * keywords.c (scm_tc16_kw): Removed deprecated type.
2792 (Replaced by scm_tc16_keyword.)
2794 * kw.h: Removed deprecated header file.
2796 * evalext.c (serial-map): Removed deprected alias for scm_map.
2797 (Has been replaced by `map-in-order'.)
2799 * ramap.c (serial-array-copy!, serial-array-map!): Removed
2800 depracted aliases. (Replaced by `array-copy-in-order!' and
2801 `array-map-in-order'.)
2803 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2805 * gc.h (SCM_VALIDATE_CELL): Rewritten.
2806 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
2807 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
2808 (Thanks to Han-Wen Nienhuys.)
2810 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
2812 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
2813 write it to the temp file first and check the CPP return code.
2814 (I introduced this bug earlier, and this probably caused people
2815 with non-GNU C preprocessors to get empty *.x files and not to
2816 have the build fail right away...).
2818 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
2819 -- at least my libc5-based Linux system doesn't define SIGSYS.
2821 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2823 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
2824 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
2825 (Thanks to Bernard Urban.)
2827 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2829 * modules.c (scm_system_module_env_p): Fixed detection of system
2832 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
2834 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
2835 `program error signals' because they can't currently be handled by
2838 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2840 * procs.h (SCM_SET_SUBRF): Added.
2842 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
2843 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
2846 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2848 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
2851 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
2852 scm_merge_list_step): Don't take the address of SCM_CAR. Use
2853 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
2855 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2857 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
2858 replacement for !SCM_FALSEP.
2860 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
2861 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
2862 (scm_primitive_load), print.c (scm_simple_format), procs.c
2863 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
2864 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
2865 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
2866 (scm_string_to_obarray_symbol), throw.c (scm_catch,
2867 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
2868 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
2869 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
2870 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
2872 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2874 * eval.c (scm_badformalsp): New static function.
2875 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
2876 (Thanks to Keisuke Nishida.)
2878 The major reason for Guile's slow loading speed has been the fact
2879 that a chain of Scheme level procedures has been evaluated for
2880 every top-level symbol lookup during the first pass through the
2883 The following is a kludge which I suggested four years ago, and
2884 which I've repeatedly suggested since. Personally, I've never
2885 been bothered by Guile's slow loading speed, so I thought I would
2886 let someone else do it...
2888 But since the new environments will be included first in
2889 Guile-1.5, I thought it would make people happy to get the kludge
2892 * modules.c: Added #include "libguile/vectors.h";
2893 Added #include "libguile/hashtab.h";
2894 Added #include "libguile/struct.h";
2895 Added #include "libguile/variable.h";
2896 Capture Scheme level `module-make-local-var!' to be used in the
2897 standard eval closure.
2898 (scm_standard_eval_closure): New primitive.
2900 * modules.h (scm_standard_eval_closure): Declare.
2902 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
2903 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
2905 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
2906 standard eval closures.
2908 * variable.c: Code layout fixes.
2910 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2912 * Makefile.am: Added LIBS line to libpath which accidentally
2913 disappeared in the change of 2000-06-01.
2914 (Thanks to Dale P. Smith.)
2916 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2918 * scmsigs.c (scm_segfault): Removed. (Was probably added by
2919 mistake since it is not mentioned in ChangeLog.)
2921 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
2922 avoid compiler warnings in gcc. (Does this work for other
2925 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2927 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
2929 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
2930 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
2931 the address of these expressions since they use SCM_VALIDATE_CELL.
2932 (Thanks to Bernard Urban.)
2934 * dynl.c: Changed #include <ltdl.h> --> #include
2935 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
2937 2000-06-01 Craig Brozefsky <craig@red-bean.com>
2939 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
2940 from GUILE-VERSION definition of LIBGUILE version. Added to
2941 libpath.h definitions for guileversion and libguileversion which
2942 both get their values from GUILE-VERSION definition.
2944 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2946 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
2947 file: Code using numbers should not be required to include
2950 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2952 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
2953 mit-pthreads.c, mit-pthreads.h: Deleted.
2955 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
2956 references to deleted files and fsu/mit thread support in
2959 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2961 * hooks.c (symbol_name, scm_create_hook): Restored the original
2962 behaviour of scm_create_hook. Changing it was bad as Carl
2963 R. Witty has pointed out.
2965 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
2968 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2970 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
2971 soon not be done by scm_create_hook any longer.
2973 * hooks.c (make_hook, print_hook, scm_create_hook,
2974 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
2975 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
2976 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
2977 longer have names. As an intermediate solution, the name
2978 predicate is emulated via object properties, but use of this
2979 feature is deprecated.
2981 * hooks.h (scm_free_hook): Removed, as it is never defined.
2983 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2985 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
2986 Un-deprecated since otherwise user code can't determine whether a
2987 number fits into an inum any longer. The names should be changed
2990 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
2992 * tags.h (SCM_UNPACK_CAR): Deprecated.
2994 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2996 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
2997 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
2998 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
2999 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
3000 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
3001 SCM_{SET}?C[AD]R unless they are known to be cons cells.
3003 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
3004 init_heap_seg): Remove unused struct member variable 'valid'.
3006 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
3008 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
3009 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
3010 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
3011 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
3012 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
3015 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3017 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
3018 (scm_macro_type), objects.c (scm_class_of), options.c
3019 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
3020 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
3022 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3024 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
3025 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
3027 * eval.c (scm_force): Add documentation.
3029 * eval.c (scm_force, scm_cons_source): Don't access cells via
3030 SCM_{SET}?C[AD]R unless they are known to be cons cells.
3032 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3034 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
3035 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
3037 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
3038 nosve #endif conditionally compiled code.
3040 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
3042 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
3044 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
3046 * guile-doc-snarf.in: put the preprocessed file through sed to
3047 trim all lines to 1024 chars. I hope it doesn't break anybody's
3048 sed. we'll see. (note: this is lossy trimming, i.e. the spill
3049 isn't wrapped around but actually chopped off. this seemed to me
3050 safe because the current snarfer doesn't understand multi-line
3051 cookies anyway. in the long term, it would be nice not to depend
3052 on AWK for anything.)
3054 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
3055 the previous change to this macros, after deciding to torture the
3058 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
3060 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
3061 the yucky, ugly and nasty conditional compilation back. sorry,
3062 but it was either that or requiring GAWK to build Guile.
3063 (lots of places): removed the code that implemented the old GC
3066 * init.c (scm_boot_guile_1): removed the code conditioned on
3067 !GUILE_NEW_GC_SCHEME.
3069 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
3071 * gc.c (scm_protect_object, scm_unprotect_object): change the
3072 implementation to more efficient (at least in the time complexity
3073 sense). the calls should now also be thread-safe -- I suspect
3074 that people expect them to be. (thanks to Han-Wen Nienhuys)
3075 (lots of places): removed the code that implemented the old GC
3078 * hashtab.c (scm_hash_fn_create_handle_x): add missing
3079 SCM_REALLOW_INTS before return. I really wonder about the
3080 possible interactions between hashtables, threads & GC. it
3081 doesn't look healthy at all.
3083 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3085 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
3088 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
3090 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
3091 debug option to verify all accesses to cells actually access
3092 objects on the heap.
3094 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
3095 SCM_DEBUG_CELL_ACCESSES is set to 1.
3097 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
3098 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
3101 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
3103 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
3104 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
3106 * gc.c (scm_cellp): Fixed and simplified.
3108 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
3109 make_jmpbuf, scm_init_throw): Now using double cells to represent
3110 jump buffers when using debug extensions.
3114 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3116 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
3117 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
3118 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
3119 gh_module_lookup): Accept const pointers as parameters.
3121 * gh.h gh_data.c (gh_int2scmb): Deprecated.
3123 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3125 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
3126 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
3127 the actual arguments in the list, but rather the rest argument as
3128 a list of arguments.
3130 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
3132 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
3133 (scm_list_star, scm_append, scm_append_x), ports.c
3134 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
3135 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
3136 (scm_make_stack), strings.c (scm_string_append), struct.c
3137 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
3139 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
3140 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
3141 (scm_dynamic_link): Removed possibility to pass flags to
3142 scm_dynamic_link, as it had no effect anyway.
3144 * filesys.c (scm_fcntl): Made single optional rest argument into
3145 a standard optional argument.
3147 * hooks.c (scm_run_hook): A list of rest arguments is never
3150 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
3151 strings.c (scm_string_append): Don't perform half-hearted checks
3152 to see whether the rest argument forms a proper list any more, use
3153 SCM_VALIDATE_REST_ARGUMENTS instead.
3155 * ports.c (scm_close_all_ports_except): Accept empty list of rest
3158 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
3159 Simplify verification of rest argument.
3161 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
3162 (ss_handler, handler_message): Make first mandatory rest argument
3163 of scm_make_stack into a standard mandatory argument.
3165 * unif.c (scm_transpose_array, scm_enclose_array,
3166 scm_array_in_bounds_p), unif.h (scm_transpose_array,
3167 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
3168 rest argument into a standard mandatory argument.
3170 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
3172 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
3173 Keisuke Nishida for the suggestion.) Added debug option
3174 SCM_DEBUG_REST_ARGUMENTS.
3176 * eval.c (scm_map, scm_for_each): Make sure all lists have the
3177 same length. Also, removed redundant parameter checks.
3179 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3181 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
3183 * __scm.h: Improved explanation of giving options to make.
3185 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
3186 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
3187 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
3188 corresponding declaration and comment to __scm.h.
3190 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
3191 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
3192 SCM_INUM): Removed conditionally compiled code for Turbo C.
3194 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
3195 That check can be assumed to be redundant except for very rare
3196 conditions that actually indicate broken heap data.
3198 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3200 * numbers.c (scm_logcount, scm_integer_length): Reordered
3203 2000-05-15 Gary Houston <ghouston@arglist.com>
3205 * stime.c (scm_strftime): don't reset TZ if zone is an empty
3206 string. append a "0" to the zone for TZ.
3208 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
3210 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
3213 (scm_bit_extract): Fixed handling of bignums.
3215 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
3217 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
3218 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
3219 (scm_sysmissing), error.h (scm_sysmissing), evalext.c
3220 ('serial-map), ioext.c (scm_fseek), ioext.h (scm_fseek),
3221 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
3222 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
3223 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
3224 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
3225 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
3226 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
3228 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
3229 scm_output_port_p), print.c (scm_get_print_state), validate.h
3230 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
3231 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
3232 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
3234 2000-05-14 Gary Houston <ghouston@arglist.com>
3236 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
3237 TZ environment variable so that the %Z format returns the zone
3238 from the input vector instead of the system default.
3240 from Keisuke Nishida:
3241 * fports.c (scm_setvbuf): minor docstring fix.
3242 * ports.h (scm_generic_fgets): obsolete prototype deleted.
3244 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
3246 * __scm.h: Added new section for debugging options.
3248 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
3249 help developers to get rid of references to deprecated code.
3251 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
3252 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
3253 as part of the interface and are marked as deprecated in the
3256 * numbers.c (scm_make_real, scm_make_complex): Inlined the
3257 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
3260 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
3261 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
3262 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
3264 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3266 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
3267 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
3268 of two scm_bits_t values instead of two SCM values, because it is
3269 legal for cell entries to hold values that are not scheme objects.
3271 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
3272 Use SCM_SETC[AD]R to modify contents of pairs.
3274 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3276 * numbers.c (IS_INF, isfinite): Added FIXME comment.
3278 (scm_abs, scm_magnitude): Make these two independent of each
3279 other. scm_abs now reports an error if given a complex argument.
3281 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
3282 SCM_REALPART if the object is known to be real.
3284 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
3287 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
3289 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3291 * eq.c (scm_eqv_p): Separate handling of real and complex
3292 values. Remove #ifdef SCM_BIGDIG #endif test.
3294 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
3295 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
3296 ramap_rp, scm_array_map_x), random.c (vector_scale,
3297 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
3298 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
3299 the object is known to be real. Use SCM_COMPLEXP instead of
3300 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
3303 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3305 * numbers.c: No need to include unif.h.
3307 (IS_INF): Returned to old test for now: x == x + 1 will not work
3308 for large numbers due to rounding errors.
3309 Thanks to Kalle Olavi Niemitalo.
3311 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
3313 * numbers.c (scm_divbigdig): Removed outdated comment.
3315 (scm_number_to_string, scm_string_to_number, scm_number_p,
3316 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
3317 scm_geq_p, scm_make_rectangular, scm_make_polar,
3318 scm_inexact_to_exact): Added comments.
3320 (add1, scm_init_numbers): Removed add1.
3322 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
3324 * numbers.c (IS_INF): The new test is x == x + 1. The old test
3325 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
3328 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
3329 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
3332 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
3334 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
3335 SIGILL and SIGBUS signals. These signals are not continuable and
3336 must be handled for real right away.
3338 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
3340 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
3341 scm_real_part, scm_imag_part, scm_magnitude,
3342 scm_inexact_to_exact): Reordered dispatch sequence.
3344 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
3346 * feature.c: No need to include "libguile/smob.h"
3348 (scm_loc_features, features, scm_add_feature, scm_init_feature):
3349 Removed variable 'scm_loc_features' as a pointer to the SCM value
3350 holding the features list. Using variable 'features' instead,
3351 which holds the interned pair. Thus, SCM_SETCDR can be used
3352 instead of pointer trickery.
3354 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
3356 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
3357 cell is not known to be a valid pair.
3359 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
3361 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
3362 ASRTSYNTAX. Using SCM_ASSYNT instead.
3364 (scm_m_body): Don't create a redundant cons cell.
3366 (scm_m_do): Removed redundant test 'bodycheck'.
3368 (bodycheck): Removed.
3370 * stacks.c (stack_depth, read_frame, read_frames): Removed
3371 redundant calculation of size, minimized some variable scopes.
3373 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3375 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
3376 long as a cell is not known to be a valid pair.
3378 (scm_pair_p): Eliminated redundant SCM_IMP test.
3380 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3382 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
3383 scm_deval_args): Eliminated redundant SCM_IMP tests.
3385 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
3386 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
3387 scm_make_doubly_weak_hash_table): Fixed critical sections.
3388 Thanks to Keisuke Nishida.
3390 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3392 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
3393 Fixed some goto-related initialization bugs (introduced by me).
3395 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
3397 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
3399 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
3401 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
3404 (SET_DYNL_HANDLE): Added.
3406 (scm_dynamic_object_p): Simplified.
3408 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
3409 better error message when accessing unlinked dynamic objects.
3410 Eliminated call to get_dynl_obj.
3412 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
3414 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
3415 be an array of function pointers instead of being a pointer to an
3416 array returning function. Thanks to Kalle Olavi Niemitalo!
3418 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
3420 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
3421 (scm_divbigbig, scm_divbigint): Don't return zero any more to
3422 indicate that a division has a remainder, return SCM_UNDEFINED
3423 instead. It is improbable that anyone actually used these
3424 functions outside of numbers.c. For this reason and due to the
3425 change in behaviour the functions are static now. Thus, if
3426 surprisingly there are users of these functions they will at least
3429 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
3430 that already have a clean dispatch order. Note: SCM_BIGDIG is
3433 * numbers.c (scm_inexact_p): Simplified.
3435 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
3436 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
3437 sequence, thereby fixing some comparisons of SCM values with
3440 * numbers.c (scm_divide): Division by zero of inums leads to an
3441 error now. (Formerly, an infinite number was returned.)
3443 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED

3967 * iselect.c (add_fd_sets): Insert empty statement after label.
3968 (Thanks to Tim Mooney.)
3970 2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
3972 * guardians.c (scm_guardian_zombify): mark all zombies in a
3973 separate loop after processing all the currently known live
3974 guardians, so as to not introduce order dependencies (thanks to
3975 Gary Houston). note that the order problems are still there if
3976 some guardians are themselves zombies, but that's a sick case that
3977 I'm not going to worry about.
3978 also, make another outer loop to process zombified
3979 guardians (which are uncovered while marking zombies).

4065 2000-04-02 Gary Houston <ghouston@arglist.com>
4067 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
4068 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
4069 use of an improper list (which breaks g_print. g_print isn't
4071 guardians.c: Added more comments and modified the make-guardian
4072 docstring. Reordered a few procedures.

4121 binary compatibility---let's remove it next time we alter some
4124 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
4125 coop_mother, coop_child): New variables.
4126 (mother): New function.
4127 (coop_create): New thread spawning mechanism which uses a "mother
4128 thread". The "dummy" pthreads aren't healthy enough to give birth
4129 to new threads since Linux threads thinks they are asleep.
4131 * coop-defs.h (struct coop_t): Removed dummy_mutex.
4133 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
4134 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
4136 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
4138 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
4139 (scm_internal_dynamic_wind): Smob data is always of type
4142 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
4143 Access the locking information in cell entry 0 with
4144 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.

4159 Don't use C operators == and != to compare SCM values, use
4162 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
4163 SCM value is equal to #t or #f.
4165 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
4166 cell type entry of non immediate objects of unknown type. Use

4182 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
4184 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
4186 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
4188 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
4189 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
4190 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
4192 Note that this implies that smob data has always to be passed as
4193 values of type scm_bits_t.
4195 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4197 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
4198 for scm_tc16_thread. As the current COOP threads are written, GC
4199 is not supposed to manage storage for threads.
4201 * error.c (scm_error): Don't try to throw an error if
4202 scm_gc_heap_lock is true.
4204 * coop.c (coop_finish): New function. Called at exit.
4205 (coop_aborthelp): Free thread structures when threads die.
4206 Finished LinuxThreads compatibility support => COOP threads now
4207 mesh with LinuxThreads.
4209 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
4210 Changed SETCDR --> SET_CELL_WORD_1.
4212 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
4215 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
4217 * boolean.h (SCM_TRUE_P): New macro.
4219 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
4220 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
4222 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4224 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
4225 access continuation data.
4227 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
4229 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
4230 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
4233 * continuations.c (scm_make_cont), init.c (start_stack),
4234 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
4237 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4239 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
4240 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
4242 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
4243 to access the char * field of strings and symbols.
4245 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
4247 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
4248 the type entry of a new cell. Added a comment about things to
4249 remember when updating the list of free cells.
4251 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
4254 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
4256 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
4257 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
4258 with strict type checking enabled these macros will only work if
4259 given valid SCM parameters.
4261 (SCM_GCCDR): Moved to tags.h.
4263 * tags.h (SCM_GCCDR): Moved here from pairs.h.
4265 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
4267 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
4269 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
4270 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
4271 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
4272 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
4273 SCM_NEWCELL2): Moved to gc.h.
4275 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
4276 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
4277 be changed, though, since the macros are not only pair related.
4281 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
4282 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
4283 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
4284 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
4285 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
4286 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
4289 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
4291 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
4292 activates strict compile time type checking for variables of
4294 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
4295 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
4296 (SCM_EQ_P): Defined as a macro equivalent for eq?.
4298 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
4300 * tags.h (SCM_POINTERS_MUNGED): Removed.
4302 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
4303 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
4305 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4307 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
4308 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
4309 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
4311 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
4313 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
4314 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
4316 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4318 * tags.h: Disabled definition of SCM_VOIDP_TEST.
4320 Defining SCM as void * introduces problems which haven't been
4321 handled yet. Developers who work with these issues can enable it
4322 in their working copies.
4324 Disabling this definition exposes a set of newly introduced and
4325 older misuses of types which causes warning messages during
4326 compilation. We'll fix this successively.
4328 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
4329 in order to obtain a value of type SCM.
4330 (scm_cellp): Updated with new changes to scm_mark_locations.
4332 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
4334 * continuations.c (scm_make_cont): Removed cast of size_t into
4337 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
4339 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
4341 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
4342 shifting, not constant. Thanks to Dale P. Smith.
4344 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
4345 for being less than zero. Decode it to a C value first. Again,
4348 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
4350 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
4351 non scheme values. If raw data is stored in SCM variables, it has
4352 to be accessed using SCM_UNPACK until a better solution is found.
4354 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4356 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
4357 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
4359 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
4361 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
4363 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
4365 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
4367 * async.c, __scm.h: Removed lots of the old async click logic. It
4368 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
4369 __scm.h. Let's try this out and dump the old code after the
4370 threads reorganization.
4371 (set-tick-rate, set-switch-rate): Conditionally removed.
4373 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4375 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
4376 made SCM values into pointers. This turned an arithmetic
4377 computation of the address of the vcell into a pointer-arithmetic
4378 one, thereby screwing up marking of structs.
4379 Bugfix 2: Removed incompletely introduced loop variable `j' used
4380 when protecting the tail array of a struct.
4382 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4384 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
4386 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4388 * symbols.h, symbols.c (scm_strhash): Declare the string
4389 parameter as constant, since it is not modified.
4391 * symbols.c (scm_intern_obarray_soft,
4392 scm_sysintern0_no_module_lookup): Can now pass constant strings
4393 to scm_strhash without need for casting.
4395 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4397 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
4398 values to pointers. Use SCM2PTR instead.
4400 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4402 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
4403 results of SCM_INUM.
4405 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4407 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
4408 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
4409 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
4411 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
4412 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
4413 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
4414 gc_trigger, adjust_gc_trigger.
4416 * gc.c (alloc_some_heap): Further improvement of minimal heap size
4418 (SCM_MAX): New macro.
4419 (scm_freelist_t): New field: collected_1. Previous amount of
4421 (gc_sweep_freelist_finish): Trigger based on two last values of
4422 freelist->collected to avoid unnecessary allocation due to
4424 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
4425 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
4426 without extra heap allocation.
4428 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4430 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
4431 already be a C value. No need to unpack it.
4433 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
4434 if we know it fits into an inum.
4436 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
4437 field of long values. In contrast, SCM_VELTS accesses a field of
4440 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4442 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
4444 (scm_gc_yield_1): New variable: Holds previous yield. Used to
4445 make better judgements.
4446 (gc_sweep_freelist_finish): Inserted explanation of use of
4449 * print.h, stacks.h, options.c, options.h: Changed C++
4452 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4454 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
4456 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
4457 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
4458 SCM_UNPACK / SCM2PTR correctly.
4460 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4462 * gc.c (adjust_gc_trigger): Improved documentation.
4463 (alloc_some_heap): Since gc_trigger is used against
4464 freelist->collected, this is the value which should be used to
4465 predict minimum growth.
4467 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4469 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
4470 Thien-Thi Nguyen for the patch.)
4472 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4474 * numbers.c (scm_ash): Fixed typing problems with the second
4475 parameter and added some documentation. (Thanks Thien-Thi Nguyen
4476 for indicating the problem.)
4478 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4480 * gc.c, gc.h (scm_gc_yield): New variable.
4481 (adjust_gc_trigger): Use scm_gc_yield.
4482 (alloc_some_heap): Use scm_gc_yield instead of
4483 scm_gc_cells_collected.
4485 * coop-threads.c: Addd #include "root.h", #include "strings.h".
4487 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
4489 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
4490 trigger adjustmeant: Take yield (freed cells) for all freelists
4492 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
4493 to 50000 cell heap with 45% trigger.
4494 (scm_gc_cells_collected): Reintroduced.
4495 (SCM_HEAP_SIZE): New macro.
4496 (scm_gc_sweep): Reintroduced correct computation of
4497 scm_cells_allocated.
4498 (scm_freelist_t): Corrected commentary for field `cluster_size':
4499 Clustersize counts objects, not cells; New member
4500 `clusters_allocated'.
4502 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
4504 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
4507 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4509 * threads.h: Added #include "libguile/throw.h". (Thanks to
4512 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
4514 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
4515 names, anyone got any better ones?)
4517 * gc.h: (typedef struct scm_freelist_t) remove from here.
4519 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
4520 parameter (the span).
4521 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
4522 (typedef struct scm_freelist_t) moved here from gc.h, it had no
4523 business being externally visible.
4524 (typedef struct scm_heap_seg_data_t) renamed from
4525 scm_heap_seg_data, to be style-compliant.
4526 (scm_mark_locations) if the possible pointer points to a
4527 double-cell, check that it's properly aligned.
4528 (init_heap_seg) align double-cells properly, work with the
4529 assumption that the segment size divides cleanly by cluster size.
4530 (round_to_cluster_size) new function.
4531 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
4532 to satisfy the new init_heap_seg invariant.

4591 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4593 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
4594 Cluster sizes are now independent of GC trigger values.
4595 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
4596 A negative integer gives fraction of total heap size in percent.
4597 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
4599 * init.c (scm_boot_guile_1): Introduced new variable
4600 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
4601 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
4602 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
4604 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4606 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
4607 freeing of segment work with the new GC scheme. (Thanks to
4608 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
4609 the default, but I'll let this change stay in CVS Guile since this
4610 code is not expected to contain serious bugs.
4612 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4614 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
4616 (scm_free_list_length): New procedure (GUILE_DEBUG).
4617 Fixed a small but serious bug introduced by the previous change.
4619 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
4620 loop and declare as register.
4622 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
4625 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4627 * fluids.c: Docstring patch from Keisuke Nishida. Some
4628 reindentation, too, and a couple formals renamed. Should
4629 fluid-set! return UNSPECIFIED instead of a value?
4631 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
4633 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
4634 generate the latter from the concrete listing of the former. Then
4635 make guile-procedures.txt depend on DOT_DOC_FILES instead of
4636 *.doc, so that rebuilding it works.
4638 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
4640 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
4642 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
4643 with nothing and \n, respectively. Thanks Keisuke Nishida for
4644 noticing this problem.
4646 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4648 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
4649 new way of allocating heap. It makes Guile fast, but still
4652 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
4653 allocating heap. The basic idea is to trigger GC every Nth
4654 allocated cell and grow heap when free list runs out. The scheme
4655 has been extended so that GC isn't triggered until all remaining
4656 cells are used. The implementation is also prepared for
4657 development in the direction of POSIX threads.
4659 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
4660 SCM_EXPHEAP should return half of the heap size.
4662 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4664 The following change to init.c is only enabled if Guile was
4665 configured with --enable-guile-debug.
4667 * init.c (scm_i_getenv_int): New function.
4668 (scm_boot_guile_1): Use the environment variables
4669 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
4670 they exist. (This may be replaced by a Scheme level mechanism in
4673 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
4674 scm_assoc. (Thanks to Keisuke Nishida.)
4676 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4678 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
4679 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
4681 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4683 * init.c (scm_boot_guile_1): Use same initial segment size for
4684 1-word and 2-word segments. Having the smaller size causes Guile
4685 to GC too often. Obviously something needs to be done to allow
4686 for a smaller 2-word segment without this to happen. (The amount
4687 of heap for each type should be automatically adapted to the
4688 application somehow.)
4690 [Almost all of these changes should be documented in the NEWS
4693 * gc.h (scm_freelist_t): New type.
4695 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
4697 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
4698 all of Guile basics fits into one segment and there suitable room
4700 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
4702 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
4703 Freelists now contains information about object span, cells
4704 collected and amount of cells in heap segments belonging to the
4706 (scm_heap_size, scm_gc_cells_collected): Removed.
4708 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
4710 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
4713 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
4714 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
4715 rewrite of handling of real and complex numbers.
4716 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
4717 removed along with the support for floats. (Float vectors are
4720 * tags.h (scm_tcs_bignums): Removed.
4721 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
4722 Use SCM_BIGSIGN(x) to test for sign!
4723 (scm_tc16_big): The new bignum type.
4724 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
4726 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
4727 (scm_makdbl): Deprecated.
4728 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
4729 (SCM_SINGP): Deprecated.
4731 (SCM_INEXP, SCM_CPLXP): Deprecated.
4732 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
4733 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
4734 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
4735 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
4736 for doubles and complex numbers.
4737 (SCM_REAL_VALUE): New selector for doubles.
4738 (scm_double_t, scm_complex_t): New types.
4741 * numbers.c (scm_floprint, scm_floequal): Removed.
4742 (scm_print_real, scm_print_complex, scm_real_equalp,
4743 scm_complex_equalp): New functions.
4745 * unif.c (scm_makflo): Removed.
4747 * smob.h (SCM_SMOB_PREDICATE): New macro.
4748 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
4749 SCM_RETURN_NEWSMOB3): New macros.
4751 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
4753 The following changes implement primitive support for double cells
4754 (i.e. four-word cells) and change the representation of some
4755 things to multi-cells instead of cons+malloc. (Applied and
4758 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
4759 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
4760 multi-cell access macros (used by the ones below).
4761 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
4764 * gc.c (scm_freelist2): multi-cell freelists.
4765 (inner_map_free_list): map_free_list, parameterized on ncells.
4766 "nn cells in segment mm" was misleading for ncells > 1; changed to
4767 "objects". still print cells too, though.
4768 (scm_map_free_list): rewritten using inner_map_free_list.
4769 (scm_check_freelist): get freelist as parameter, since now we have
4771 (scm_debug_newcell2): multi-cell variants of
4773 (scm_gc_for_newcell): take ncells and freelist pointer as
4775 (scm_gc_mark): add case for tc7_pws (procedures with setters are
4777 (scm_gc_sweep): don't free the float data, since it's not malloced
4779 (init_heap_seg): didn't understand what n_new_objects stood for,
4780 so changed to n_new_cells.
4781 (make_initial_segment): new function, makes an initial segment
4782 according to given ncells.
4783 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
4785 * numbers.c (scm_makdbl): no malloc'ing needed, so the
4786 {DEFER,ALLOW}_INTS thing removed.
4788 * numbers.h (struct scm_dbl): changed to represent a double cell,
4789 with the number in the second half.
4791 * dynwind.c: changed the wind-guards representation to double
4794 * procs.c, procs.h: changed the procedure-with-setter representation
4797 * async.c, async.h: made async representation a double cell.
4799 * dynl.c: made dynamic_obj representation a double cell.
4801 2000-03-13 Gary Houston <ghouston@arglist.com>
4803 * ports.c (flush_void_port): renamed to flush_port_default.
4804 (end_input_void_port): renamed to end_input_default.
4806 * init.c (scm_standard_stream_to_port): create a void port instead
4807 of opening /dev/null if the standard file descriptors are bad.
4808 advantages: no portability problems, doesn't waste a file descriptor,
4809 simplifies the code (thanks to Marius for the idea).
4811 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
4813 * void ports: make reading from a void port give EOF instead of
4815 * ports.c (s_scm_sys_make_void_port): modified docstring.
4816 (fill_input_void_port): new proc.
4817 (scm_init_ports): set up fill_input_void_port.
4818 * ports.c (scm_port_non_buffer): new proc.
4819 (scm_void_port): call scm_port_non_buffer.
4821 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
4822 which was incorrectly appended.
4824 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4826 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
4827 that we can't use autoconf for this. Autoconf itself relies on
4828 the existence of `sed' somewhere on your path.) (Thanks to Dirk
4831 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4833 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
4834 EXTRA_libguile_la_SOURCES.
4836 * iselect.h: Always declare scm_internal_select.
4838 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
4839 end. Also let scm_internal_select be a real function also when
4842 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
4844 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4846 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
4847 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
4848 and kind of an experiment: Will this cause problems?)
4850 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
4852 * Makefile.am: Added *.doc to DISTCLEANFILES.
4854 2000-03-12 Gary Houston <ghouston@arglist.com>
4856 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
4857 the fdes is valid before doing anything else. check that
4858 the file descriptor supports the modes required.
4859 (scm_fport_buffer_add): don't throw an error if fstat doesn't
4860 work: just use the default buffer size.
4862 * throw.c: change an outdated comment about scm_internal_catch
4863 BODY: it doesn't take a jumpbuf arg.
4865 * init.c (scm_standard_stream_to_port): install a handler in case
4866 scm_fdes_to_port throws an error. don't check here whether the
4867 file descriptor is valid, since scm_fdes_to_port will do that.
4868 set the revealed count depending on whether the port got the
4869 standard file descriptor.
4870 (stream_body_data): new type.
4871 (stream_body, stream_handler): new procs.
4873 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4875 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
4876 Renamed from SCMWORD.
4878 * tags.h (SCM_NCELLP): Removed (SCMWORD).
4880 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
4882 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
4883 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

4888 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
4889 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
4890 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
4892 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
4894 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
4895 tags.h: Fixed copyright notices.
4897 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
4899 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
4901 * init.c (scm_standard_stream_to_port): Check whether the file
4902 descriptor is valid and substitute "/dev/null" when not.
4904 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4906 * coop-defs.h (struct timespec): Conditionally defined.
4908 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
4911 * readline.c (match_paren): Bugfix: First arg to select is not
4912 number of descriptors but the number of the highest descriptor +
4915 This is a preliminary attempt at a cleanup of the threads support
4916 code. It moves things to better places, makes arguments more
4917 consistent with the POSIX API (which is used in GNOME's glib), and
4918 adds new functionality.
4920 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
4922 * coop-defs.h (scm_mutex_trylock): New macro: alias for
4924 (scm_cond_init): Changed definition to
4925 coop_new_condition_variable_init.
4927 * coop.c: #include <errno.h>
4928 (coop_timeout_qinsert): Moved here from iselect.c
4929 (coop_new_mutex_init, coop_new_condition_variable_init): New
4930 functions. The strange names are temporary. Use scm_mutex_init
4931 and scm_cond_init instead.
4932 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
4933 is ANSI C, but should we check for individual error codes in
4935 (coop_condition_variable_timed_wait_mutex): New function.
4936 (coop_key_create, coop_setspecific, coop_getspecific,
4937 coop_key_delete): New functions.
4939 * iselect.c (coop_timout_qinsert): Moved to coop.c
4941 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4943 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
4944 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
4946 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
4949 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
4950 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
4951 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
4953 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
4956 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
4958 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
4959 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
4960 logical functions from SCM.
4962 (logand, logior, logxor, logtest, logbit?): Extended scheme
4963 logical functions to use bignums from SCM.
4965 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
4966 lognot from using bignums.
4968 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
4970 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
4971 eliminating some warnings.
4973 * unif.c, strports.c, print.c, options.c: Fix some warnings on
4976 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
4977 what the scm_return_first* functions do.
4979 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
4981 * libguile/*.[ch]: make a distinction between SCM as a generic
4982 name for a Scheme object (now a void*), and SCM as 32 bit word for
4983 storing tags and immediates (now a long int). Introduced
4984 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
4985 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
4987 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
4989 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
4990 various logXXX primitives. Thanks Eric Moore!
4992 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
4994 * run-test, remaining-docs-needed: Added these scripts. The
4995 second one is only temporary until the docstring additions are
4996 complete. run-test may best live on, but is here mostly for
4997 convenience and awareness for now.
4999 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
5001 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
5003 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
5004 displaying the expected type. Use SCM_LISTn in a couple places
5005 instead of scm_cons-ing by hand.
5007 * __scm.h: Added SCM_ASSERT_TYPE macro.
5009 * validate.h, scm_validate.h: Added the former, as a renamed
5010 version of the latter with SCM_ASSERT_TYPE used in
5011 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
5013 * Makefile.am: Rename scm_validate.h to validate.h.
5015 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
5016 prefix was superfluous).
5018 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
5020 * hashtab.c: Improved documentation for lots of functions. Added
5021 handwritten docs for `hash-fold'.
5023 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
5025 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
5027 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
5029 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
5030 added append docs from R4RS.
5032 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
5033 Thanks Dirk Hermann!
5035 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
5036 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
5038 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
5039 Drop use of SCM_P for function prototypes... assume an ANSI C
5040 compiler. Thanks Dirk Hermann!
5042 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
5044 * ports.c: Made `set-port-column!' and `set-port-line!' each
5045 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
5046 that caused a seg fault. Also fixed `set-port-column!'s
5047 docstring. Thanks Han-Wen Nienhuys for finding the bug!
5049 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
5051 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
5052 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
5053 strings.c, variable.c: Added lots of documentation, cleaned up
5054 some existing documentation. Occasionally changed formal params
5055 to match docs. Also folded an #ifdef into the inners of a
5056 primitive instead of having two copies of the primitive
5057 (`get-internal-real-time', from stime.c)
5059 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
5061 * ports.c: Added docs for primitives missing them. Written by
5064 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
5066 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
5067 just execing guile-func-name-check. Thanks Michael Livshin!
5069 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
5071 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
5072 dead code. Patch from Michael Livshin.
5074 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
5077 2000-02-09 Gary Houston <ghouston@arglist.com>
5079 * init.c (scm_init_standard_ports): when stdout is a tty, make the
5080 current-output-port unbuffered by default. this is less confusing
5081 for interactive use. it was line-buffered because of a
5082 performance problem with unbuffered ports, but I think it will be
5085 2000-02-08 Gary Houston <ghouston@arglist.com>
5087 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
5090 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
5091 HAVE_TZNAME are defined, use an empty string instead of giving two
5092 spurious compile-time errors.
5094 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
5096 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
5099 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
5101 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
5103 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
5105 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
5106 (which is GNU GPL'd).
5108 2000-01-31 Gary Houston <ghouston@arglist.com>
5110 * strings.h: don't use SCM_P. don't include <string.h>.
5111 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
5113 * strings.c (scm_string_ref): make the 2nd argument compulsory.
5114 previously it defaulted to zero for no good reason that I can see.
5115 use a local variable for SCM_INUM (k). replace
5116 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
5118 (scm_makfromstr): cosmetic changes.
5120 (scm_string): Accept only chars in the list, not strings, for
5121 conformance to R5RS (particularly for list->string, which is
5122 supposed to be the inverse of string->list.) remove
5123 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
5124 scm_makstr handles the cell allocation. when reporting wrong-type
5125 arg, don't report the position as 1.
5127 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
5129 2000-01-29 Gary Houston <ghouston@arglist.com>
5131 * posix.c (scm_pipe): rewrote the docstring.
5133 * filesys.c (scm_select, retrieve_select_type, get_element,
5134 fill_select_type, set_element): modified so that Scheme
5135 "select" tests port buffers for the ability to provide input
5136 or accept output. Previously only the underlying file descriptors
5137 were checked. Rewrote the docstring.
5139 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
5141 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
5142 from Gregg Reynolds. Thanks Gregg!
5144 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
5146 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
5147 adding "x" prefix to the line so that guile-func-name-check
5148 doesn't complain unnecessarily.
5150 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
5152 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
5153 for maintainability.
5155 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
5158 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
5160 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
5161 suggests removing tag.c altogether (and using a new `class-of'
5164 * strings.c: Added documentation from Gregg A. Reynolds. Edited
5165 a bit by me to use FOO instead of @var{foo} and to have the
5166 summary come before preconditions on input. Also dropped trailing
5169 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
5170 function with scm_make_subr_opt w/ last arg of 0 so it is not
5171 visible at the Scheme level. Mikael says that this is the right
5172 thing because the first arg to the proc is the guts of a compiled
5173 closure and shouldn't be exposed to the Scheme level.
5175 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
5177 * sort.c: typo in comment fixed.
5179 * keywords.c: Added documentation.
5181 * guardians.c: Added documentation (could be better).
5183 * gc.c: Added docs for gc-set-debug-check-freelist.
5185 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
5187 * boolean.c: Added docs for `not', `boolean?' (by hand).
5189 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
5191 * random.c: Added documentation, from SLIB page:
5192 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
5194 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
5196 * variable.c, version.c: Added documentation, written by hand
5197 since I could not find anything already written that was
5200 2000-01-23 Gary Houston <ghouston@arglist.com>
5202 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
5203 not defined (thanks to Richard Y. Kim).
5205 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
5207 * Makefile.in: Removed, this is auto-generated.
5209 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
5211 * list.c: Put some variable initialization code at the point of
5212 declaration; Added a comment for list*; Formatting changes.
5214 * load.c: use SCM_NNULLP to make sure the end of a list is not
5217 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5219 * backtrace.c (scm_display_error_message): Bugfix: Don't use
5220 result of scm_list_p as C boolean.
5221 (scm_display_error_message, scm_set_print_params_x): Use new
5222 validation macros. (Thanks to Dirk Herrmann.)
5224 * net_db.c (scm_resolv_error): Cast result from hstrerror.
5226 * strports.c (st_end_input): Inserted parenthesis to get operator
5229 * list.h (scm_init_list): Removed SCM_P around prototypes.
5231 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
5232 filesys.c, posix.c: Converted docstrings to ANSI C format and
5233 escaped " occurring inside string literals.
5235 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
5237 * posix.c (scm_mknod): Escape " occuring inside docstring.
5239 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5241 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
5242 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
5243 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
5244 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
5245 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
5246 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
5247 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
5248 weaks.c: Converted docstrings to ANSI C format.
5250 * filesys.c (scm_chmod), simpos.c (scm_system), version
5251 (scm_version), vports (scm_make_soft_port): Escape " occuring
5254 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
5256 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
5257 SCM_VALIDATE_LONG_COPY
5259 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
5260 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
5261 couple of formal arguments (and fix their uses) to make arguments
5262 match the documentation.
5264 2000-01-14 <mstachow@alum.mit.edu>
5266 * Makefile.am: Augment path when running guile-doc-snarf so
5267 guile-func-name-check is found.
5269 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
5271 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
5272 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
5274 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
5276 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
5277 the way guile-1.3.4 worked, but #if 0 out the version using
5278 SCM_VALIDATE_INUM_COPY for stricter testing.
5280 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
5282 * guile-doc-snarf.in: Use new $fullfilename for running
5283 guile-func-name-check, and put "$fullfilename" and "$filename" in
5284 quotes at uses to make sure re-splitting on whitespace does not
5285 occur (so filenames w/ embedded whitespace would work okay, though
5286 I sure hope we never have to deal with that! :-) ). Thanks to
5287 Mikael for pointing out the source_dir != build_dir was broken.
5289 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
5291 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
5292 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
5293 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
5294 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
5297 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
5298 then return whether it's an open port (was validating that it was
5299 an open port -- this was a bug I introduced back in December, but
5300 my careful reading of diffs caught it).
5302 * numbers.c: Recombine the two conditional-compilation paths for
5303 all the log* primitives -- they were split based on #ifndef
5304 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
5305 some bugs and inconsistencies in the two sets of implementations.
5306 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
5308 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
5309 SCM_VALIDATE_INUM_COPY once where it should've been used.
5311 * fluids.c (scm_internal_with_fluids): Use
5312 SCM_VALIDATE_LIST_COPYLEN.
5314 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
5315 this is questionable as it relaxes type safety, but other changes
5316 were useful and all SCM_NUM2LONG's should probably be
5317 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
5319 * evalext.c: line-break change on 1 line.
5321 * eval.c (nconc2last): Takes a non-empty list as its first
5322 argument, not just a list.
5324 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
5326 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
5328 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
5329 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
5332 * symbols.c (scm_sysintern0): Fixed the function name in a
5333 scm_misc_error invocation.
5335 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
5336 use scm_return_first to ward off latent GC bug that Mikael caught.
5338 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
5339 used before but should've been.
5341 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5343 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
5344 SCM_FUNC_CAST_ARBITRARY_ARGS.
5346 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
5348 * guile-func-name-check.in: Added this script to statically check
5349 #define FUNC_NAME, #undef FUNC_NAME in the source.
5351 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
5352 redundant comment, semicolon; caught by new guile-func-name-check
5355 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
5356 Caught by new guile-func-name-check-script.
5358 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
5360 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
5361 guile-func-name-check.
5363 * guile-doc-snarf.in: Run guile-func-name-check on the file before
5366 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
5368 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
5369 port function take const void*, not void*.
5371 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
5373 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
5374 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
5375 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
5376 consistency with the other macros dealing with immediate
5377 characters. (Similar to INT -> INUM change a week or so ago).
5379 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
5381 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
5382 net_db.c, read.c, socket.c: Update error messages to use ~A for
5383 %s, ~S for %S to work with new `simple-format' format and be
5384 standardized better.
5386 * print.h, print.c (scm_simple_format): Added `simple-format'
5387 primitive. It's the old scm_display_error, with ARGS now a rest
5388 parameter, and the destination first instead of last (and a couple
5389 new capabilities inspired by `format' -- #t as destination means
5390 current-output-port, #f means return the formatted text as a
5393 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
5395 * backtrace.c (scm_display_error_message): Rewrote to use
5396 scm_simple_format() procedure.
5398 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
5400 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
5402 Finally applied the libltdl patch from Thomas Tanner, with slight
5405 * DYNAMIC-LINKING: Removed because it is obsolete.
5406 * dynl.c: Use ANSI prototypes.
5407 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
5408 * scmconfig.h.in: Do not change, as it is automatically generated.
5410 1999-07-25 Thomas Tanner <tanner@ffii.org>
5412 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
5414 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
5415 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
5417 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
5418 * guile.c: register preloaded modules
5419 * scmconfig.h.in: remove obsolete symbols
5421 2000-01-09 Gary Houston <ghouston@arglist.com>
5423 * These changes should make it unnecessary to call tzset from
5424 Scheme after modifying the TZ environment variable, even if the
5425 system date facilities cache the value.
5426 * stime.c (setzone, scm_localtime): added comments.
5427 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
5428 (setzone): don't call tzset.
5429 (restorezone): call tzset only if HAVE_TZSET is defined.
5430 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
5431 doc string to indicate that this procedure isn't likely to do
5433 (scm_localtime, scm_strftime, scm_mktime): call tzset if
5434 LOCALTIME_CACHE is defined.
5436 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5438 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
5440 2000-01-09 Gary Houston <ghouston@arglist.com>
5442 * eval.c: define scm_unbound_variable_key ('unbound-variable).
5443 scm_lookupcar1: throw an error with key 'unbound-variable instead
5444 of 'misc-error when an unbound variable is encountered.
5446 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
5447 scm_symlink, scm_readlink, scm_lstat),
5448 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
5449 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
5451 simpos.c (scm_system),
5452 stime.c (scm_times, scm_strptime):
5453 move the HAVE_XXX feature tests out of the procedure bodies.
5454 don't use SCM_SYSMISSING.
5455 scm_validate.h (SCM_SYSMISSING): removed.
5456 error.h, error.c (scm_sysmissing): comment that this is deprecated.
5457 see ChangeLog entry for 1999-12-28.
5459 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
5461 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
5463 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
5465 * backtrace.c: Fix spelling typo in a comment.
5467 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
5468 text. Reformatted some of the expansions.
5470 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
5472 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
5473 report the position of the argument.
5475 * error.h, error.c (scm_out_of_range_pos): Added this function to
5476 take extra "pos" argument, the position number of the errant
5479 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
5481 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
5482 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
5483 prefers that and I'm reasonably indifferent.
5485 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
5487 * snarf.h: Factor out differences between C++ and non-C++ into
5488 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
5489 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
5490 Mikael's macros, below, but changed names and SCM_SNARFING no
5491 longer expands to include %%% -- that must appear in the argument
5492 so that the token appears at the call-site as a reminder).
5494 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5496 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
5497 snarf macro definitions.
5499 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5501 * chars.c (scm_integer_to_char): Use Greg's nice
5502 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
5505 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
5507 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
5509 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
5511 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
5512 instead of GUILE_PROC.
5514 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
5516 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
5517 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
5520 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
5522 * scm_validate.h: Remove some redundant NIMP tests.
5524 * alist.c: minimize scope of the tmp variables, and initialize
5525 them when declared. The strange SCM_NIMP tests are replaced by
5526 SCM_CONSP tests that more closely reflect the intended semantics.
5527 However, we don't get a performance penalty here, because the
5528 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
5529 extremely ugly use of ASRTGO macros was removed: The calls to
5530 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
5531 label parameter that only exists when SCM_RECKLESS is not defined.
5532 This works, because ASRTGO itself is defined in a way that it only
5533 makes use of the label parameter if SCM_RECKLESS is not defined
5534 (shudder!). Does guile make at all use of the possibility to
5535 define SCM_RECKLESS? * Codesize is likely to be reduced, since
5536 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
5537 we now only get one test.
5539 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
5540 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
5541 some variables in `list?'. Fix `reverse' and `reverse!'
5542 primitives to handle improper lists better.
5544 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
5546 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
5547 macros and SCM_DEFINE macros to match GNU coding standards.
5549 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
5551 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
5553 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
5555 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
5556 better consistency with the names of other SCM_VALIDATE_ macros
5557 and better conformance to guile naming policy.
5559 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
5561 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
5562 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
5563 it's not the actual name of the formal).
5565 * guile-snarf.awk.in: Do argument/number mismatch checking and
5566 print warnings in an Emacs compile-mode parseable format.
5568 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
5569 SCM_OUTOFRANGE as 3rd argument.
5571 * random.c: Fix argument/number mismatch (that I introduced :-( ).
5573 * __scm.h: Do not #define SCM_ARG* when snarfing;
5574 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
5575 the former (using the number) requires the argument to match the
5576 formal in the current argument snarfing check.
5578 * snarf.h: Give new definition of SCM_ASSERT when in
5579 snarfing mode to output a lexically-identifiable sequence that the
5580 guile-snarf.awk script uses to verify argument/position matching.
5582 * ramap.c: Remove extraneous #undef FUNC_NAME.
5584 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
5586 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
5587 current version of the same functionality; it writes the .x output
5588 to stdout instead of directly into the file.
5590 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
5592 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
5593 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
5594 redundant with the safer macros. Patch from Dirk Hermann applied
5595 by hand. Thanks Dirk!
5597 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
5600 * ramap.c: whitespace change.
5602 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
5604 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
5605 removals from Dirk Hermann.
5607 * alist.c: Rename formals to match the parameter names in the
5608 documentation, updates to documentation. Thanks Dirk Hermann!
5610 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5612 * eval.c (SCM_CEVAL): Reverse order of
5613 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
5614 (Thanks to Brad Knotwell.)
5616 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
5618 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
5621 * pairs.h: Added a comment about the need for the SCM_SETCAR in
5624 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
5626 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
5627 SCM_NIMP tests that were redundant are now eliminated. Patches
5628 from Dirk Hermann applied by hand.
