(emacsclient${EXEEXT}): Use it. * lib-src/emacsclient.c (main): Use fdatasync, not fsync, since we don't care about metadata. Keep trying if interrupted. * lib-src/movemail.c (main, popmail): Don't worry about BSD_SYSTEM, since fsync is available everywhere (or there is a substitute). Don't report an error if fsync returns EINVAL. * nt/inc/ms-w32.h (fdatasync): New macro, suggested by Eli Zaretskii. * src/Makefile.in (LIB_FDATASYNC): New macro. (LIBES): Use it. * src/conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed. * src/fileio.c (Fwrite_region, write_region_inhibit_fsync): Don't worry about HAVE_FSYNC, since a substitute fsync is available if the system lacks one.

| | | | | | | | | | | | | | * admin/grammars/java-tags.wy (CHAR): Remove "('\u0000' to '\uffff')" from summary, as this causes javat-wy.el to contain both a null byte and a byte sequence that is not valid UTF-8, which is inconvenient. * lisp/cedet/semantic/wisent/javat-wy.el: Regenerate.
* | * bzrmerge.el (bzrmerge-apply): Omit Latin-1 char from diagnostic.Paul Eggert2013-03-021-0/+5

(AC_CHECK_HEADERS_ONCE): Remove sys/resource.h, as it's not always needed. (HAVE_DATA_START): New macro. * etc/PROBLEMS (LIBS_SYSTEM, LIBS_MACHINE, LIBS_STANDARD): Remove. Remove legacy-systems section, as this stuff is no longer applicable with current linking strategies. * src/Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD) (START_FILES): Remove. All uses removed. (otherobj): Remove $(VMLIMIT_OBJ), as it's now first. (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first. (buildobj.h): Use it. ($(ALLOBJS)): Depend on globals.h. (temacs$(EXEEXT)): Use $(ALLOBJS). * src/autodeps.mk (ALLOBJS): Move to Makefile.in. * src/deps.mk (vm-limit.o): * src/makefile.w32-in ($(BLD)/vm-limit.$(O)): Do not depend on mem-limits.h. * src/emacs.c (__do_global_ctors, __do_global_ctors_aux) (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__) [__GNUC__ && !ORDINARY_LINK]: Remove. * src/mem-limits.h, src/pre-crt0.c: Remove. * src/unexaix.c, src/unexcoff.c: Don't include mem-limits.h. * src/unexcoff.c (etext): New decl. (make_hdr): Use it instead of start_of_data. * src/vm-limit.c: Move most of mem-limits.h's contents here. (data_start): New decl. It's OK if this is approximate, so simplify-away some unnecessary exactness. (POINTER): Remove; all uses removed. (data_space_start): Now char *, to avoid casts. (exceeds_lisp_ptr): New function, replacing the old EXCEEDS_LISP_PTR macro. All uses changed. (check_memory_limits): Simplify and remove casts. (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove. (memory_warnings): Use data_start instead of start_of_data. Fixes: debbugs:13783

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * .bzrignore: Add string.h. * admin/merge-gnulib (GNULIB_MODULES): Add memrchr. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/memrchr.c, lib/string.in.h, m4/memrchr.m4, m4/string_h.m4: New files, from gnulib. * src/doc.c (Fsnarf_documentation): * src/fileio.c (Fsubstitute_in_file_name): * src/search.c (find_newline, scan_newline): * src/xdisp.c (pos_visible_p, display_count_lines): Use memchr and memrchr rather than scanning byte-by-byte. * src/search.c (find_newline): Rename from scan_buffer. Omit first arg TARGET, as it's always '\n'. All callers changed.
* | Use fdopendir, fstatat and readlinkat, for efficiency.Paul Eggert2013-01-311-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On my host, this speeds up directory-files-and-attributes by a factor of 3, when applied to Emacs's src directory. These functions are standardized by POSIX and are common these days; fall back on a (slower) gnulib implementation if the host is too old to supply them. * .bzrignore: Add lib/dirent.h. * lib/Makefile.am (libgnu_a_SOURCES): Add openat-die.c, save-cwd.c. * lib/careadlinkat.c, lib/careadlinkat.h: Merge from gnulib, incorporating: 2013-01-29 careadlinkat: do not provide careadlinkatcwd. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/dirent.in.h, lib/fdopendir.c, lib/fstatat.c, lib/openat-priv.h: * lib/openat-proc.c, lib/openat.h, m4/dirent_h.m4, m4/fdopendir.m4: * m4/fstatat.m4: New files, from gnulib. * lib/openat-die.c, lib/save-cwd.c, lib/save-cwd.h: New files. These last three are specific to Emacs and are not copied from gnulib. They are simpler than the gnulib versions and are tuned for Emacs. * admin/merge-gnulib (GNULIB_MODULES): Add fdopendir, fstatat, readlinkat. (GNULIB_TOOL_FLAGS): Do not avoid at-internal, openat-h. Avoid dup, open, opendir. * nt/inc/sys/stat.h (fstatat): * nt/inc/unistd.h (readlinkat): New decls. * src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove. * src/dired.c: Include <fcntl.h>. (open_directory): New function, which uses open and fdopendir rather than opendir. DOS_NT platforms still use opendir, though. (directory_files_internal, file_name_completion): Use it. (file_attributes): New function, with most of the old Ffile_attributes. (directory_files_internal, Ffile_attributes): Use it. (file_attributes, file_name_completion_stat): First arg is now fd, not dir name. All uses changed. Use fstatat rather than lstat + stat. (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p. * src/fileio.c: Include <allocator.h>, <careadlinkat.h>. (emacs_readlinkat): New function, with much of the old Ffile_symlink_p, but with an fd argument for speed. It uses readlinkat rather than careadlinkatcwd, so that it need not assume the working directory. (Ffile_symlink_p): Use it. * src/filelock.c (current_lock_owner): Use emacs_readlinkat rather than emacs_readlink. * src/lisp.h (emacs_readlinkat): New decl. (READLINK_BUFSIZE, emacs_readlink): Remove. * src/sysdep.c: Do not include <allocator.h>, <careadlinkat.h>. (emacs_norealloc_allocator, emacs_readlink): Remove. This stuff is moved to fileio.c. * src/w32.c (fstatat, readlinkat): New functions. (careadlinkat): Don't check that fd == AT_FDCWD. (careadlinkatcwd): Remove; no longer needed. Fixes: debbugs:13539

Add type checking. * src/alloc.c, src/dired.c, src/editfns.c, src/fileio.c, src/ftfont.c: * src/gtkutil.c, src/keymap.c, src/lread.c, src/nsterm.h, src/nsmenu.c: * src/xfns.c, src/xmenu.c, src/xselect.c: All users changed. * admin/coccinelle/xsave.cocci: Semantic patch to adjust users of XSAVE_POINTER and XSAVE_INTEGER macros.

(File Attributes): Document that 9th element is now just a placeholder. * doc/lispref/os.texi (User Identification): Document new functions group-gid, group-real-gid. * etc/NEWS: Document changes to file-attributes, file-ownership-preserved-p. Mention new functions group-gid, group-real-gid. * lisp/files.el (backup-buffer): Don't rely on 9th output of file-attributes, as it's now a placeholder. Instead, use the new optional arg of file-ownership-preserved-p. (file-ownership-preserved-p): New optional arg GROUP. Fix mishandling of setuid directories that would cause this function to return t when it should have returned nil. Document what happens if the file does not exist, and when it's not known whether the ownership will be preserved. * lisp/net/tramp-sh.el (tramp-sh-handle-file-ownership-preserved-p): Likewise. (tramp-get-local-gid): Use group-gid for integer, as that's faster and more reliable. * src/dired.c (Ffile_attributes): Return t as the 9th attribute, to mark it as a placeholder. The old value was often wrong. The only user of this attribute has been changed to use file-ownership-preserved-p instead, with its new group arg. * src/editfns.c (Fgroup_gid, Fgroup_real_gid): New functions. Fixes: debbugs:13125
* | Use putenv+unsetenv instead of modifying environ directly.Paul Eggert2012-12-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/merge-gnulib (GNULIB_MODULES): Add putenv, unsetenv. * lib/putenv.c, lib/unsetenv.c, m4/putenv.m4, m4/setenv.m4: New files, copied automatically from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * src/alloc.c (xputenv): New function. * src/dbusbind.c (Fdbus_init_bus): * src/emacs.c (main): * src/xterm.c (x_term_init): Use xputenv instead of setenv or putenv, to detect memory exhaustion. * src/editfns.c (initial_tz): Move static var decl up. (tzvalbuf_in_environ): New static var. (init_editfns): Initialize these two static vars. (Fencode_time): Don't assume arbitrary limit on EMACS_INT width. Save old TZ value on stack, if it's small. (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly; instead, use xputenv+unsetenv to set and restore TZ. (environbuf): Remove static var. All uses removed. (Fset_time_zone_rule): Do not save TZ and environ; no longer needed here. (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]: Move to inside set_time_zone_rule; they don't need file scope any more. (set_time_zone_rule): Maintain the TZ=value string separately. (syms_of_editfns): Don't initialize initial_tz; init_editfns now does it. * src/emacs.c (dump_tz) [HAVE_TZSET]: Now const. * src/lisp.h (xputenv): New decl. Fixes: debbugs:13070

(SIGTRAP): Remove this one too, as config.h no longer defines it. * admin/merge-gnulib (GNULIB_MODULES): Add sig2str. * configure.ac (PTY_OPEN, PTY_TTY_NAME_SPRINTF): Use SIGCHLD rather than SIGCLD. * lib/sig2str.c, lib/sig2str.h, m4/sig2str.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/makefile.w32-in (GNULIBOBJS): Add $(BUILD)/sig2str.$(O). * src/process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

(emacs_sigaction_init): Assume SIGCHLD is defined. (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL, SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more. * src/syssignal.h (EMACS_KILLPG): Remove. All uses replaced by 'kill' with a negative pid. (SIGCHLD): Remove definition, as we now assume SIGCHLD. * src/w32proc.c (sys_kill): Support negative pids compatibly with POSIX. Fixes: debbugs:13026

Use the GNU macro _D_EXACT_NAMELEN if available, as it's faster than strlen. (DIRENTRY): Remove, replacing all uses with 'struct dirent'. (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero. * src/makefile.w32-in (DIR_H): Remove. All uses replaced with $(NT_INC)/dirent.h. ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h. * src/ndir.h: Rename to ../nt/inc/dirent.h. * src/sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove. Do not include <dirent.h>; no longer needed. * src/w32.c: Include <dirent.h> rather than "ndir.h". Fixes: debbugs:12958

All uses changed. * nt/inc/unistd.h (O_RDWR, O_NOCTTY): New macros. Like AT_FDCWD etc. these really should be moved to a replacement <fcntl.h> if and when that gets implemented. In the meantime, include <fcntl.h> to make sure we don't override its definitions. * src/callproc.c (relocate_fd): Assume F_DUPFD. * src/emacs.c, src/term.c (O_RDWR): Remove. * src/keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than O_NDELAY, since O_NONBLOCK is the standard name for this flag. * src/nsterm.m: Assume <fcntl.h> exists. * src/process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process) (create_pty, Fmake_network_process, server_accept_connection) (wait_reading_process_output, init_process_emacs): Assume O_NONBLOCK. (wait_reading_process_output): Put in a special case for WINDOWSNT to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK. It's not clear this is needed, but it's a more-conservative change. (create_process): Assume FD_CLOEXEC. (create_process, create_pty): Assume O_NOCTTY. * src/sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL. (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY. Omit if not DOS_NT, since F_GETFL is not defined there. (serial_open): Assume O_NONBLOCK and O_NOCTTY. * src/term.c: Include <fcntl.h>, for flags like O_NOCTTY. (O_NOCTTY): Remove. (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that lack it, since gnulib guarantees this. * src/w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY. Fixes: debbugs:12881
* | Remove no-longer-used pty_max_bytes variable.Paul Eggert2012-11-161-0/+5

It was reported by Chris Torek in 1983 even before GNU Emacs existed, which must set some sort of record. (Torek's bug report was against a predecessor of GNU Emacs, but GNU Emacs happened to have the same common flaw.) See Torek's Usenet posting "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858 Posted: Fri Apr 8 14:18:56 1983. * .bzrignore: Add lib/fcntl.h. * configure.ac (euidaccess): Remove check; gnulib does this for us now. (gl_FCNTL_O_FLAGS): Define a dummy version. * lib/at-func.c, lib/euidaccess.c, lib/faccessat.c, lib/fcntl.in.h: * lib/getgroups.c, lib/group-member.c, lib/root-uid.h: * lib/xalloc-oversized.h, m4/euidaccess.m4, m4/faccessat.m4: * m4/fcntl_h.m4, m4/getgroups.m4, m4/group-member.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add faccessat. (GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix, openat-die, openat-h, save-cwd. Do not avoid fcntl-h. Omit gnulib's m4/fcntl-o.m4. * nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS): New symbols. (access): Remove. (faccessat): New macro. * src/Makefile.in (LIB_EACCESS): New macro. (LIBES): Use it. * src/callproc.c (init_callproc): * src/charset.c (init_charset): * src/fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): * src/lread.c (openp, load_path_check): * src/process.c (allocate_pty): * src/xrdb.c (file_p): Use effective UID when checking permissions, not real UID. * src/callproc.c (init_callproc): * src/charset.c (init_charset): * src/lread.c (load_path_check, init_lread): Test whether directories are accessible, not merely whether they exist. * src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro. * src/fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): Use symbolic names instead of integers for the flags, as they're portable now. (check_writable): New arg AMODE. All uses changed. Set errno on failure. (Ffile_readable_p): Use faccessat, not stat + open + close. (Ffile_writable_p): No need to call check_existing + check_writable. Just call check_writable and then look at errno. This saves a syscall. dir should never be nil; replace an unnecessary runtime check with an eassert. When checking the parent directory of a nonexistent file, check that the directory is searchable as well as writable, as we can't create files in unsearchable directories. (file_directory_p): New function, which uses 'stat' on most platforms but faccessat with D_OK (for efficiency) if WINDOWSNT. (Ffile_directory_p, Fset_file_times): Use it. (file_accessible_directory_p): New function, which uses a single syscall for efficiency. (Ffile_accessible_directory_p): Use it. * src/xrdb.c (file_p): Use file_directory_p. * src/lisp.h (file_directory_p, file_accessible_directory_p): New decls. * src/lread.c (openp): When opening a file, use fstat rather than stat, as that avoids a permissions race. When not opening a file, use file_directory_p rather than stat. (dir_warning): First arg is now a usage string, not a format. Use errno. All uses changed. * src/nsterm.m (ns_term_init): Remove unnecessary call to file-readable that merely introduced a race. * src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK' changed to '#if O_NONBLOCK', to accommodate gnulib O_* style, and similarly for the other O_* flags. * src/w32.c (sys_faccessat): Rename from sys_access and switch to faccessat's API. All uses changed. * src/xrdb.c: Do not include <sys/stat.h>; no longer needed. (magic_db): Rename from magic_file_p. (magic_db, search_magic_path): Return an XrmDatabase rather than a char *, so that we don't have to test for file existence separately from opening the file for reading. This removes a race fixes a permission-checking problem, and simplifies the code. All uses changed. (file_p): Remove; no longer needed. Fixes: debbugs:12632

(setsid, tcgetpgrp): New functions. Fixes: debbugs:12800
* | Simplify by assuming __fpending.Paul Eggert2012-11-041-0/+5
| | | | | | | | | | | | | | | | | | | | | | Now that Emacs is using the gnulib fpending module, there's no need for Emacs to have a separate implementation. * configure.ac (stdio_ext.h, __fpending): Remove now-duplicate checks. (PENDING_OUTPUT_COUNT, DISPNEW_NEEDS_STDIO_EXT): Remove. * admin/CPP-DEFINES (PENDING_OUTPUT_COUNT): Remove. * src/dispnew.c: Include <fpending.h>, not <stdio_ext.h>. (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT. Do not assume that __fpending's result fits in int.

(close_output_streams): New function. (main): Pass it to atexit, so that Emacs closes stdout and stderr and handles errors appropriately. (Fkill_emacs): Don't worry about flushing, as close_output_stream does that now. Fixes: debbugs:9574
