* eval.c (block_pass): should not downgrade safe level.
* ext/dbm/extconf.rb: allow specifying dbm-type explicitly.
* ext/dbm/extconf.rb: avoid gdbm if possible, because it leaks
memory, whereas gdbm.so doesn't. potential incompatibility.
* string.c (rb_str_insert): new method.
* parse.y (yylex): lex_state after RESCUE_MOD should be EXPR_BEG.
* array.c (rb_ary_insert): new method.
* array.c (rb_ary_update): new utility function.
* io.c (set_outfile): should check if closed before assignment.
* eval.c (rb_eval): should preserve value of ruby_errinfo.
* eval.c (rb_thread_schedule): infinite sleep should not cause
dead lock.
* array.c (rb_ary_flatten_bang): proper recursive detection.
* eval.c (yield_under): need not to prohibit at safe level 4.
* pack.c (pack_pack): p/P packs nil into NULL.
* pack.c (pack_unpack): p/P unpacks NULL into nil.
* pack.c (pack_pack): size check for P template.
* ruby.c (set_arg0): wrong predicate when new $0 value is bigger
than original space.
* gc.c (id2ref): should use NUM2ULONG()
* object.c (rb_mod_const_get): check whether name is a class
variable name.
* object.c (rb_mod_const_set): ditto.
* object.c (rb_mod_const_defined): ditto.
* marshal.c (w_float): precision changed to "%.16g"
* eval.c (rb_call0): wrong retry behavior.
* numeric.c (fix_aref): a bug on long>int architecture.
* eval.c (rb_eval_string_wrap): should restore ruby_wrapper.
* regex.c (re_compile_pattern): char class at either edge of range
should be invalid.
* eval.c (handle_rescue): use === to compare exception match.
* error.c (syserr_eqq): comparison between SytemCallErrors should
based on their error numbers.
* eval.c (safe_getter): should use INT2NUM().
* bignum.c (rb_big2long): 2**31 cannot fit in 31 bit long.
* regex.c (calculate_must_string): wrong length calculation.
* eval.c (rb_thread_start_0): fixed memory leak.
* parse.y (none): should clear cmdarg_stack too.
* io.c (rb_fopen): use setvbuf() to avoid recursive malloc() on
some platforms.
* file.c (rb_stat_dev): device functions should honor stat field
types (except long long such as dev_t).
* eval.c (rb_mod_nesting): should not push nil for nesting array.
* eval.c (rb_mod_s_constants): should not search array by
rb_mod_const_at() for nil (happens for singleton class).
* class.c (rb_singleton_class_attached): should modify iv_tbl by
itself, no longer use rb_iv_set() to avoid freeze check error.
* variable.c (rb_const_get): error message "uninitialized constant
Foo at Bar::Baz" instead of "uninitialized constantBar::Baz::Foo".
* eval.c (rb_mod_included): new hook called from rb_mod_include().
* io.c (opt_i_set): should strdup() inplace_edit string.
* eval.c (exec_under): need to push cref too.
* eval.c (rb_f_missing): raise NameError for "undefined local
variable or method".
* error.c (Init_Exception): new exception NoMethodError.
NameError moved under ScriptError again.
* eval.c (rb_f_missing): use NoMethodError instead of NameError.
* file.c (Init_File): should redifine "new" class method.
* eval.c (PUSH_CREF): sharing cref node was problematic. maintain
runtime cref list instead.
* eval.c (rb_eval): copy defn node before registering.
* eval.c (rb_load): clear ruby_cref before loading.
* variable.c (rb_const_get): no recursion to show full class path
for modules.
* eval.c (rb_set_safe_level): should set safe level in curr_thread
as well.
* eval.c (safe_setter): ditto.
* object.c (rb_obj_is_instance_of): nil belongs to false, not true.
* time.c (make_time_t): proper (I hope) daylight saving time
handling for both US and Europe. I HATE DST!
* eval.c (rb_thread_wait_for): non blocked signal interrupt should
stop the interval.
* eval.c (proc_eq): class check aded.
* eval.c (proc_eq): typo fixed ("return" was ommitted).
* error.c (Init_Exception): move NameError under StandardError.
* class.c (rb_mod_clone): should copy method bodies too.
* bignum.c (bigdivrem): should trim trailing zero bdigits of
remainder, even if dd == 0.
* file.c (check3rdbyte): safe string check moved here.
* time.c (make_time_t): remove HAVE_TM_ZONE code since it
sometimes reports wrong time.
* time.c (make_time_t): remove unnecessary range check for
platforms where negative time_t is available.
* process.c (proc_waitall): should push Process::Status instead of
Finuxm status.
* process.c (waitall_each): should add all entries in pid_tbl.
these changes are inspired by Koji Arai. Thanks.
* process.c (proc_wait): should not iterate if pid_tbl is 0.
* process.c (proc_waitall): ditto.
* numeric.c (flodivmod): a bug in no fmod case.
* process.c (pst_wifsignaled): should apply WIFSIGNALED for status
(int), not st (VALUE).
* io.c (Init_IO): value of $/ and $\ are no longer restricted to
strings. type checks are done on demand.
* class.c (rb_include_module): module inclusion should be check
taints.
* ruby.h (STR2CSTR): replace to StringType() and StringTypePtr().
* ruby.h (rb_str2cstr): ditto.
* eval.c (rb_load): should not copy topleve local variables. It
cause variable/method ambiguity. Thanks to L. Peter Deutsch.
* class.c (rb_include_module): freeze check at first.
* eval.c (rb_attr): sprintf() and rb_intern() moved into
conditional body.
