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

(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

* reflected. <code>File::Stat</code> objects are returned by
* <code>IO#stat</code>, <code>File::stat</code>,
* <code>File#lstat</code>, and <code>File::lstat</code>. Many of these
* methods return platform-specific values, and not all values are
* meaningful on all systems. See also <code>Kernel#test</code>.

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

ruby/ruby.h: remove unnecessary exports from C-API Needlessly exporting can reduce performance locally and increase binary size. Increasing the footprint of our C-API larger is also detrimental to our development as it encourages tighter coupling with our internals; making it harder for us to preserve compatibility. If some parts of the core codebase needs access to globals, internal.h should be used instead of anything in include/ruby/*.

Fix compatibility of cached expanded load path * file.c (rb_get_path_check_to_string): extract from rb_get_path_check(). We change the spec not to call to_path of String object. * file.c (rb_get_path_check_convert): extract from rb_get_path_check(). * file.c (rb_get_path_check): follow the above change. * file.c (rb_file_expand_path_fast): remove check_expand_path_args(). Instead we call it in load.c. * file.c (rb_find_file_ext_safe): use rb_get_expanded_load_path() to reduce expand cost. * file.c (rb_find_file_safe): ditto. * internal.h (rb_get_expanded_load_path): add a declaration. * internal.h (rb_get_path_check_to_string, rb_get_path_check_convert): add declarations. * load.c (rb_construct_expanded_load_path): fix for compatibility. Same checks in rb_get_path_check() are added. We don't replace $LOAD_PATH and ensure that String object of $LOAD_PATH are frozen. We don't freeze non String object and expand it every times. We add arguments for expanding load path partially and checking if load path have relative paths or non String objects. * load.c (load_path_getcwd): get current working directory for checking if it's changed when getting load path. * load.c (rb_get_expanded_load_path): fix for rebuilding cache properly. We check if current working directory is changed and rebuild expanded load path cache. We expand paths which start with ~ (User HOME) and non String objects every times for compatibility. We make this accessible from other source files. * load.c (rb_feature_provided): call rb_get_path() since we changed rb_file_expand_path_fast() not to call it. * load.c (Init_load): initialize vm->load_path_check_cache. * vm.c (rb_vm_mark): mark vm->load_path_check_cache for GC. * vm_core.h (rb_vm_struct): add vm->load_path_check_cache to store data to check load path cache validity. * test/ruby/test_require.rb (TestRequire): add tests for require compatibility related to cached expanded load path.

/*
* A <code>File</code> is an abstraction of any file object accessible
* by the program and is closely associated with class <code>IO</code>.
* <code>File</code> includes the methods of module
* <code>FileTest</code> as class methods, allowing you to write (for
* example) <code>File.exist?("foo")</code>.
*
* In the description of File methods,
* <em>permission bits</em> are a platform-specific
* set of bits that indicate permissions of a file. On Unix-based
* systems, permissions are viewed as a set of three octets, for the
* owner, the group, and the rest of the world. For each of these
* entities, permissions may be set to read, write, or execute the
* file:
*
* The permission bits <code>0644</code> (in octal) would thus be
* interpreted as read/write for owner, and read-only for group and
* other. Higher-order bits may also be used to indicate the type of
* file (plain, directory, pipe, socket, and so on) and various other
* special features. If the permissions are for a directory, the
* meaning of the execute bit changes; when set the directory can be
* searched.
*
* On non-Posix operating systems, there may be only the ability to
* make a file read-only or read-write. In this case, the remaining
* permission bits will be synthesized to resemble typical values. For
* instance, on Windows NT the default permission bits are
* <code>0644</code>, which means read/write for owner, read-only for
* all others. The only change that can be made is to make the file
* read-only, which is reported as <code>0444</code>.
*
* Various constants for the methods in File can be found in File::Constants.

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
