* 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@1356 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Document-module: Errno
*
* Ruby exception objects are subclasses of <code>Exception</code>.
* However, operating systems typically report errors using plain
* integers. Module <code>Errno</code> is created dynamically to map
* these operating system errors to Ruby classes, with each error
* number generating its own subclass of <code>SystemCallError</code>.
* As the subclass is created in module <code>Errno</code>, its name
* will start <code>Errno::</code>.
*
* The names of the <code>Errno::</code> classes depend on
* the environment in which Ruby runs. On a typical Unix or Windows
* platform, there are <code>Errno</code> classes such as
* <code>Errno::EACCES</code>, <code>Errno::EAGAIN</code>,
* <code>Errno::EINTR</code>, and so on.
*
* The integer operating system error number corresponding to a
* particular error is available as the class constant
* <code>Errno::</code><em>error</em><code>::Errno</code>.
*
* Errno::EACCES::Errno #=> 13
* Errno::EAGAIN::Errno #=> 11
* Errno::EINTR::Errno #=> 4
*
* The full list of operating system errors on your particular platform
* are available as the constants of <code>Errno</code>.

(ruby-bugs PR#1220) * eval.c (rb_eval): call "inherited" only when a new class is generated; not on reopening. * eval.c (eval): prepend error position in evaluating string to * configure.in: revived NextStep, OpenStep, and Rhapsody ports which had become unbuildable; enhanced --enable-fat-binary option so that it accepts a list of desired architectures (rather than assuming a fixed list), or defaults to a platform-appropriate list if user does not provide an explicit list; made the default list of architectures for MAB (fat binary) more comprehensive; now uses -fno-common even when building the interpreter (in addition to using it for extensions), thus allowing the interpreter to be embedded into a plugin module of an external project (in addition to allowing embedding directly into an application); added checks for <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now ensures that -I/usr/local/include is employed when extensions' extconf.rb scripts invoke have_header() since extension checks on NextStep and OpenStep will fail without it if the desired resource resides in the /usr/local tree; fixed formatting of --help message. * Makefile.in: $(LIBRUBY_A) rule now deletes the archive before invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives (see configure's --enable-fat-binary option); added rule for new missing/getcwd.c. * defines.h: fixed endian handling during MAB build (see configure's --enable-fat-binary option) to ensure that all portions of the project see the correct WORDS_BIGENDIAN value (some extension modules were getting the wrong endian setting); added missing constants GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H define in NeXT section. * dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on NextStep since, on some installations, this value always resolves uselessly to zero. * dln.c: added error reporting to NextStep extension loader since the previous behavior of failing silently was not useful; now ensures that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice on Rhapsody since this header lacks multiple-include protection, which resulted in "redefinition" compilation errors. * main.c: also create hard reference to objc_msgSend() on NeXT platforms (in addition to Apple platforms). * lib/mkmf.rb: now exports XCFLAGS from configure script to extension makefiles so that extensions can be built MAB (see configure's --enable-fat-binary option); also utilize XCFLAGS in cc_command() (but not cpp_command() because MAB flags are incompatible with direct invocation of `cpp'). * ext/curses/extconf.rb: now additionally checks for presence of these curses functions which are not present on NextStep or Openstep: bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(), setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(), wscrl(), wsetscrreg() * ext/curses/curses.c: added appropriate #ifdef's for additional set of curses functions now checked by extconf.rb; fixed curses_bkgd() and window_bkgd() to correctly return boolean result rather than numeric result; fixed window_getbkgd() to correctly signal an error by returning nil rather than -1. * ext/etc/etc.c: setup_passwd() and setup_group() now check for null pointers before invoking rb_tainted_str_new2() upon fields extracted from `struct passwd' and `struct group' since null pointers in some fields are common on NextStep/OpenStep (especially so for the `pw_comment' field) and rb_tainted_str_new2() throws an exception when it receives a null pointer. * ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(). * ext/socket/getaddrinfo.c: cast first argument of getservbyname(), gethostbyaddr(), and gethostbyname() from (const char*) to non-const (char*) for older platforms such as NextStep and OpenStep. * ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(); include <netinet/in_systm.h> if present for NextStep and OpenStep; cast first argument of gethostbyaddr() and getservbyname() from (const char*) to non-const (char*) for older platforms. * ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@5002 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
