* Prefer stpcpy to strcatPaul Eggert2014-12-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/merge-gnulib (GNULIB_MODULES): Add stpcpy. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/stpcpy.c, m4/stpcpy.m4: New files, from gnulib. * lib-src/ebrowse.c (sym_scope_1, operator_name, open_file): * lib-src/emacsclient.c (get_server_config, set_local_socket) (start_daemon_and_retry_set_socket): * lib-src/etags.c (main, C_entries, relative_filename): * lib-src/pop.c (sendline): * lib-src/update-game-score.c (main): * lwlib/xlwmenu.c (resource_widget_value): * src/callproc.c (child_setup): * src/dbusbind.c (xd_signature_cat): * src/doc.c (get_doc_string, Fsnarf_documentation): * src/editfns.c (Fuser_full_name): * src/frame.c (xrdb_get_resource): * src/gtkutil.c (xg_get_file_with_chooser): * src/tparam.c (tparam1): * src/xfns.c (xic_create_fontsetname): * src/xrdb.c (gethomedir, get_user_db, get_environ_db): * src/xsmfns.c (smc_save_yourself_CB): Rewrite to avoid the need for strcat, typically by using stpcpy and/or lispstpcpy. strcat tends to be part of O(N**2) algorithms. * src/doc.c (sibling_etc): * src/xrdb.c (xdefaults): Now a top-level static constant.
* Replace union hack with C11-style max_align_tPaul Eggert2014-12-121-1/+1
| | | | | | | * admin/merge-gnulib (GNULIB_MODULES): Add stddef, for max_align_t. * lib/gnulib.mk: Regenerate. * src/alloc.c (XMALLOC_BASE_ALIGNMENT): Use max_align_t instead of a hack involving a union.
* Merge from gnulibPaul Eggert2014-12-121-0/+1
| | | | | | | | | | 2014-12-12 stddef: support C11's max_align_t 2014-12-08 apply _GL_ATTRIBUTE_PURE to some inline functions 2014-12-02 support GNU format printf and scanf on mingw * doc/misc/texinfo.tex, lib/stat-time.h, lib/stddef.in.h: * lib/timespec.h, m4/extensions.m4, m4/stddef_h.m4, m4/stdio_h.m4: Update from gnulib. * lib/gnulib.mk: Regenerate.

* Vector-sorting fixes.Paul Eggert2014-08-301-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | It's not safe to call qsort or qsort_r, since they have undefined behavior if the user-specified predicate is not a total order. Also, watch out for garbage-collection while sorting vectors. * admin/merge-gnulib (GNULIB_MODULES): Add vla. * configure.ac (qsort_r): Remove, as we no longer use qsort-like functions. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/vla.h, m4/vararrays.m4: New files, copied from gnulib. * lib/stdlib.in.h, m4/stdlib_h.m4: Sync from gnulib, incorporating: 2014-08-29 qsort_r: new module, for GNU-style qsort_r The previous two files' changes are boilerplate generated by admin/merge-gnulib, and should not affect Emacs. * src/fns.c: Include <vla.h>. (sort_vector_predicate) [!HAVE_QSORT_R]: Remove. (sort_vector_compare): Remove, replacing with .... (inorder, merge_vectors, sort_vector_inplace, sort_vector_copy): ... these new functions. (sort_vector): Rewrite to use the new functions. GCPRO locals, since the predicate can invoke the GC. Since it's in-place return void; caller changed. (merge): Use 'inorder', for clarity. Fixes: debbugs:18361

* Use libcrypto's checksum implementations if available, for speed.Paul Eggert2013-12-081-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | On commonly used platform libcrypto uses architecture-specific assembly code, which is significantly faster than the C code we were using. See Pádraig Brady's note in <http://lists.gnu.org/archive/html/bug-gnulib/2013-12/msg00000.html>. Merge from gnulib, incorporating: 2013-12-07 md5, sha1, sha256, sha512: add gl_SET_CRYPTO_CHECK_DEFAULT 2013-12-07 md5, sha1, sha256, sha512: add 'auto', and set-default method 2013-12-04 include_next: minimize code duplication 2013-12-03 md5, sha1, sha256, sha512: support mandating use of openssl 2013-12-02 md5, sha1, sha256, sha512: use openssl routines if available * configure.ac (--without-all): Set with_openssl_default too. Use gl_SET_CRYPTO_CHECK_DEFAULT to default to 'auto'. (HAVE_LIB_CRYPTO): New var. Say whether Emacs is configured to use a crypto library. * lib/gl_openssl.h, m4/absolute-header.m4, m4/gl-openssl.m4: New files, copied from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/md5.c, lib/md5.h, lib/sha1.c, lib/sha1.h: * lib/sha256.c, lib/sha256.h, lib/sha512.c, lib/sha512.h: * m4/include_next.m4, m4/md5.m4, m4/sha1.m4, m4/sha256.m4, m4/sha512.m4: Update from gnulib. * src/Makefile.in (LIB_CRYPTO): New macro. (LIBES): Use it.
* Merge from gnulib.Paul Eggert2013-10-121-0/+1
| | | | | | | | | | This incorporates: 2013-10-10 strtoumax: port to Solaris 8 2013-10-09 strtoimax, strtoumax: port to HP-UX 11.11 * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/inttypes.in.h, lib/strtoimax.c, m4/inttypes.m4, m4/strtoimax.m4: * m4/strtoumax.m4: Update from gnulib.
* Improve support for popcount and counting trailing zeros.Paul Eggert2013-10-071-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do this by using the Gnulib modules for this. This should generate faster code on non-GCC, non-MSC platforms, and make the code a bit more portable, at least in theory. * admin/merge-gnulib (GNULIB_MODULES): Add count-one-bits and count-trailing-zeros. * lib/count-one-bits.c, lib/count-one-bits.h: * lib/count-trailing-zeros.c, lib/count-trailing-zeros.h: * m4/count-one-bits.m4, m4/count-trailing-zeros.m4: New files, copied from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * nt/gnulib.mk: Merge changes from lib/gnulib.mk. * src/data.c: Include <count-one-bits.h>, <count-trailing-zeros.h>. (USE_MSC_POPCOUNT, POPCOUNT_STATIC_INLINE) (NEED_GENERIC_POPCOUNT, popcount_size_t_generic) (popcount_size_t_msc, popcount_size_t_gcc): Remove; now done by Gnulib. (popcount_size_t): Now a macro that defers to Gnulib. (count_trailing_zero_bits): Return int, for consistency with Gnulib and because Emacs prefers signed to unsigned int. Don't assume that size_t is either unsigned int or unsigned long or unsigned long long. (size_t_to_host_endian): Do not assume that size_t is either exactly 32 or exactly 64 bits wide. * src/lisp.h (BITS_PER_SIZE_T): Define consistently with BITS_PER_LONG etc., so that it's now an enum constant, not a macro. No need to assume that it's either 32 or 64. Fixes: debbugs:15550
* Use hardware support for byteswapping on glibc x86 etc.Paul Eggert2013-10-041-1/+24
| | | | | | | | | | | | | On Fedora 19 x86-64, the new bswap_64 needs 1 instruction, whereas the old swap64 needed 30. * admin/merge-gnulib (GNULIB_MODULES): Add byteswap. * lib/byteswap.in.h, m4/byteswap.m4: New files, copied from Gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * src/fringe.c (init_fringe_bitmap) [WORDS_BIGENDIAN]: * src/sound.c (le2hl, le2hs, be2hl) [!WINDOWSNT]: Use byteswap.h's macros to swap bytes. * src/lisp.h (swap16, swap32, swap64): Remove. All uses replaced by bswap_16, bswap_32, bswap_64.
* Merge from gnulib.Paul Eggert2013-10-031-0/+1
| | | | | | | | | | * src/conf_post.h (__has_builtin, assume): Remove; gnulib now does these. * src/lisp.h: Include <verify.h>, for 'assume'. This also incorpoprates: 2013-10-02 verify: new macro 'assume' 2013-09-26 dup2, dup3: work around another cygwin crasher 2013-09-26 getdtablesize: work around cygwin issue
* Fix some minor races in hosts lacking mkostemp.Paul Eggert2013-08-041-1/+31
| | | | | | | | | | | | | | | | | | | | | | Gnulib's emulation of mkostemp doesn't have races that Emacs's does. * configure.ac (mkostemp): Remove check for this function; gnulib does the check now. (mkstemp): Remove check for this no-longer-used function. * lib/mkostemp.c, lib/secure_getenv.c, lib/tempname.c, lib/tempname.h: * m4/mkostemp.m4, m4/secure_getenv.m4, m4/tempname.m4: New files, copied from Gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add mkostemp. * lib-src/movemail.c (main): * lib-src/update-game-score.c (write_scores): Use mkostemp (which now works on all platforms, due to changes in the portability layer) rather than mktemp (which has a race) or mkstemp (which we no longer bother with). * src/callproc.c (create_temp_file): * src/filelock.c (create_lock_file): Assume mkostemp, since it's now provided by Gnulib. Fixes: debbugs:15015
* Port recent close-on-exec changes to Cygwin.Paul Eggert2013-07-091-1/+7
| | | | | | | | | | * lib/binary-io.c, lib/binary-io.h: New files. Merge from gnulib, incorporating: 2013-07-09 accept4, dup3, pipe2: port to Cygwin * lib/pipe2.c: Update from gnulib, as part of this merge. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. Fixes: debbugs:14821
* Handle errno and exit status a bit more carefully.Paul Eggert2013-07-091-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib/ignore-value.h: Remove this gnulib-imported file. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Remove ignore-value. * src/callproc.c (child_setup) [!DOS_NT]: Don't try to stuff an error number into an exit status. Instead, use EXIT_CANCELED. (child_setup) [!MSDOS]: Avoid possible deadlock with vfork. * src/callproc.c (relocate_fd): * src/emacs.c (close_output_streams, main): * src/process.c (create_process): * src/sysdep.c (sys_subshell) [!DOS_NT || !WINDOWSNT]: Use emacs_perror for simplicity. * src/callproc.c (relocate_fd, main): * src/sysdep.c (sys_subshell): Exit with EXIT_CANCELED etc., not 1, when exec setup fails. (shut_down_emacs): Use emacs_write, not write. * src/emacs.c, src/sysdep.c: Don't include <ignore-value.h>. * src/fileio.c (Fcopy_file, e_write): * src/nsterm.m (ns_select): * src/process.c (send_process): * src/sound.c (vox_write): Use emacs_write_sig, not emacs_write. * src/lisp.h (emacs_write_sig, emacs_perror): New decls. * src/process.h (EXIT_CANCELED), EXIT_CANNOT_INVOKE, EXIT_ENOENT): New constants. * src/sysdep.c (emacs_backtrace): Use emacs_write, not ignore_value of write. (emacs_full_write): New function. (emacs_write): Rewrite to use it. (emacswrite_sig, emacs_perror): New functions. * src/xrdb.c (fatal): Don't invoke perror, since errno might be garbage.
* Make file descriptors close-on-exec when possible.Paul Eggert2013-07-071-3/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies Emacs a bit, since it no longer needs to worry about closing file descriptors by hand in some cases. It also fixes some unlikely races. Not all such races, as libraries often open files internally without setting close-on-exec, but it's an improvement. * admin/merge-gnulib (GNULIB_MODULES): Add fcntl, pipe2. (GNULIB_TOOL_FLAGS): Avoid binary-io, close. Do not avoid fcntl. * configure.ac (mkostemp): New function to check for. (PTY_OPEN): Pass O_CLOEXEC to posix_openpt. * lib/fcntl.c, lib/getdtablesize.c, lib/pipe2.c, m4/fcntl.m4: * m4/getdtablesize.m4, m4/pipe2.m4: New files, taken from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * nt/gnulib.mk: Remove empty gl_GNULIB_ENABLED_verify section; otherwise, gnulib-tool complains given close-on-exec changes. * nt/inc/ms-w32.h (pipe): Remove. * nt/mingw-cfg.site (ac_cv_func_fcntl, gl_cv_func_fcntl_f_dupfd_cloexec) (gl_cv_func_fcntl_f_dupfd_works, ac_cv_func_pipe2): New vars. * src/alloc.c (valid_pointer_p) [!WINDOWSNT]: * src/callproc.c (Fcall_process) [!MSDOS]: * src/emacs.c (main) [!DOS_NT]: * src/nsterm.m (ns_term_init): * src/process.c (create_process): Use 'pipe2' with O_CLOEXEC instead of 'pipe'. * src/emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]: * src/filelock.c (create_lock_file) [HAVE_MKOSTEMP]: Prefer mkostemp with O_CLOEXEC to mkstemp. * src/callproc.c (relocate_fd) [!WINDOWSNT]: * src/emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD. No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're now using pipe2. * src/filelock.c (create_lock_file) [! HAVE_MKOSTEMP]: Make the resulting file descriptor close-on-exec. * src/lisp.h, src/lread.c, src/process.c (close_load_descs, close_process_descs): * src/lread.c (load_descriptor_list, load_descriptor_unwind): Remove; no longer needed. All uses removed. * src/process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system. (close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]: New functions. (socket) [!SOCK_CLOEXEC]: Supply a substitute. (Fmake_network_process, Fnetwork_interface_list): (Fnetwork_interface_info, server_accept_connection): Make newly-created socket close-on-exec. * src/sysdep.c (emacs_open, emacs_fopen): Make new-created descriptor close-on-exec. * src/w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs. * src/w32.c, src/w32.h (pipe2): Rename from 'pipe', with new flags arg. Fixes: debbugs:14803
* Use Gnulib ACL implementation, for benefit of Solaris etc.Paul Eggert2013-05-071-1/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac: Remove -with-acl option, since Gnulib does that for us now. (LIBACL_LIBS): Remove; no longer needed. * lib/Makefile.am (CLEANFILES, SUFFIXES): New (empty) macros, for the benefit of the new ACL implementation. * lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/acl-errno-valid.$(O). ($(BLD)/acl-errno-valid.$(O)): New rule. * lib/acl-errno-valid.c, lib/acl-internal.h, lib/acl.h: * lib/acl_entries.c, lib/errno.in.h, lib/file-has-acl.c: * lib/qcopy-acl.c, lib/qset-acl.c, m4/acl.m4, m4/errno_h.m4: New files, taken from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add qacl. (GNULIB_TOOL_FLAGS): Do not avoid errno. * etc/NEWS: Emacs is no longer limited to POSIX ACLs. --disable-acl, not --without-acl, since we're now using Gnulib's implementation. * nt/config.nt (HAVE_ACL_SET_FILE): Rename from HAVE_POSIX_ACL. * nt/inc/ms-w32.h (EOPNOTSUPP): New macro. * src/Makefile.in (LIB_ACL): New macro. (LIBACL_LIBS): Remove. (LIBES): Use LIB_ACL, not LIBACL_LIBS. * src/fileio.c: Include <acl.h>. Use HAVE_ACL_SET_FILE rather than HAVE_POSIX_ACL. (ACL_NOT_WELL_SUPPORTED): Remove. All uses replaced by !acl_errno_valid. (Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling it ourselves. Fixes: debbugs:14295
* File synchronization fixes.Paul Eggert2013-03-131-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/CPP-DEFINES (BSD_SYSTEM, HAVE_FSYNC): Remove. * admin/merge-gnulib (GNULIB_MODULES): Add fsync, fdatasync. * configure.ac (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed. (fsync): Remove check; now done by gnulib. * lib/fdatasync.c, lib/fsync.c, m4/fdatasync.m4, m4/fsync.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib-src/Makefile.in (LIB_FDATASYNC): New macro. (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. (Fwrite_regin): Retry fsync if interrupted. Fixes: debbugs:13944
* Tune by using memchr and memrchr.Paul Eggert2013-02-111-1/+110
| | | | | | | | | | | | | | | * .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.
* Merge from gnulib.Paul Eggert2013-02-081-0/+2

* Use fdopendir, fstatat and readlinkat, for efficiency.Paul Eggert2013-01-311-1/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

(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

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.

(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

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.

(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

(GNULIB_TOOL_FLAGS): Avoid threadlib; this is now a prerequisite of gnulib's pthread_sigmask module, but Emacs doesn't need it. (mkdir): install-sh is now in build-aux. * config.bat: c++defs.h is now in build-aux/snippets. * configure.in: Specify AC_CONFIG_AUX_DIR with build-aux (the usual parameter). * lib/gnulib.mk, m4/gl-comp.m4: Regenerate. * lib/makefile.w32-in (ARG_NONNULL_H): arg-nonnull.h moved to build-aux/snippet. * lib/pthread_sigmask.c, lib/stdlib.in.h, m4/extensions.m4: * m4/getopt.m4, m4/gnulib-common.m4, m4/pthread_sigmask.m4: Merge from gnuilib. This fixes porting bugs on Cygwin, Irix, and Solaris, enables MacOS extensions, and enables nocrash during 'configure'. * make-dist: Adjust to new build-aux and build-aux/snippit dirs. * admin/notes/copyright: The files compile, config.guess, config.sub, depcomp, install-sh, missing, and move-if-change are now in the new build-aux subdirectory. The files arg-nonnull.h, c++defs.h, and warn-on-use.h are now in build-aux/snippets.
