* | Vector-sorting fixes.Paul Eggert2014-08-303-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Simplify previous patch.Paul Eggert2014-08-101-10/+8
| | | | | | | | Fixes: debbugs:18232
| * Don't prevent random file systems from being unmounted.Paul Eggert2014-08-102-27/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix relies on having the 'fchdir' function, and on having "." be searchable (or at least readable, on platforms lacking O_SEARCH), but that's good enough to handle the vast majority of cases and the remaining folks can just live with the annoyance of file systems that occasionally can't be unmounted. * configure.ac (fchdir): New function to check for. * lib/save-cwd.c: Copy from gnulib, except omit the part that allocates memory, since that can cause problems in Emacs. * lib/save-cwd.h: Copy from gnulib. Fixes: debbugs:18232
| * Backport fcntl.h AIX fix from the trunk.Paul Eggert2014-06-111-0/+16
| | | | | | | | | | | | | | | | | | This fixes a bug with the shell freezing. See: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17598#185 Merge from gnulib, incorporating: 2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1 * lib/fcntl.in.h, m4/dup2.m4, m4/fcntl.m4: Update from gnulib.
| * Fix port to 32-bit AIX with xlc.Paul Eggert2014-05-301-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This doesn't fix Bug#17598, but it does fix a regression since Emacs built with xlc until recently, and perhaps it'll help us fix Bug#17598. * configure.ac (GC_SETJMP_WORKS): Define for AIX, too. Merge from gnulib, incorporating: 2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1 * lib/ftoastr.c: Update from gnulib. * src/alloc.c (gdb_make_enums_visible): Remove FLOAT_TO_STRING_BUFSIZE. * src/conf_post.h (FLEXIBLE_ARRAY_MEMBER) [__IBMC__]: Don't define to empty. * src/lisp.h (FLOAT_TO_STRING_BUFSIZE): Make it a macro, instead of an enum, to work around a compiler bug in IBM xlc 12.1.

* Use libcrypto's checksum implementations if available, for speed.Paul Eggert2013-12-0810-34/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Merge from gnulib.Paul Eggert2013-11-081-1/+1
| | | | | | | | This incorporates: 2013-11-08 extern-inline: port better to OS X 10.9 2013-11-08 fpending: fix regression on DragonFly BSD * lib/fpending.h, m4/extern-inline.m4, m4/fpending.m4: Update from gnulib.
* Port to stricter C99 platforms.Paul Eggert2013-11-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Especially, C99 prohibits nesting a struct X inside struct Y if struct X has a flexible array member. Also, merge from gnulib, incorporating: 2013-11-03 intprops: port to Oracle Studio c99 * lib/intprops.h: Update from gnulib. * src/alloc.c (struct sdata): New type. (sdata): Implement in terms of struct sdata. Remove u member; all uses replaced by next_vector, set_next_vector. (SDATA_SELECTOR, SDATA_DATA, SDATA_DATA_OFFSET): Adjust to sdata change. (SDATA_DATA_OFFSET): Now a constant, not a macro. (struct sblock): Rename first_data member to data, which is now a flexible array member. All uses changed. (next_vector, set_next_vector, large_vector_vec): New functions. (vector_alignment): New constant. (roundup_size): Make it a multiple of ALIGNOF_STRUCT_LISP_VECTOR, too. (struct large-vector): Now merely a NEXT member, since the old approach ran afoul of stricter C99. All uses changed to use large_vector_vec or large_vector_offset. (large_vector_offset): New constant. * src/dispnew.c: Include tparam.h, for tgetent. Do not include term.h; no longer needed. * src/gnutls.c (Fgnutls_boot): Don't continue after calling a _Noreturn. * src/lisp.h (ENUM_BF) [__SUNPRO_C && __STDC__]: Use unsigned int. (struct Lisp_Vector): Use a flexible array member for contents, instead of a union with a member that is an array of size 1. All uses changed. (ALIGNOF_STRUCT_LISP_VECTOR): New constant, to make up for the fact that the struct no longer contains a union. (struct Lisp_Misc_Any, struct Lisp_Marker, struct Lisp_Overlay) (struct Lisp_Save_Value, struct Lisp_Free): Use unsigned, not int, for spacers, to avoid c99 warning. (union specbinding): Use unsigned, not bool, for bitfield, as bool is not portable to pre-C99 hosts.
* Merge from gnulib.Paul Eggert2013-10-221-1/+1
| | | | | | | | This incorporates: 2013-10-14 acl: allow cross-compilation to Gentoo 2013-10-18 extern-inline: make safe for -Wundef usage 2013-09-30 fpending: use pure+const function attrs * lib/fpending.h, m4/acl.m4, m4/extern-inline.m4: Update from gnulib.

| | | | | | | | | | 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 Eggert2013-10-075-1/+269
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Eggert2013-10-042-1/+68
| | | | | | | | | | | | | 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.

| | | | | | | | | | * 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
* Merge from gnulib.Paul Eggert2013-09-242-5/+5
| | | | | | | | | This incorporates: 2013-09-24 manywarnings: enable nicer gcc warning messages 2013-09-23 warnings: port --enable-gcc-warnings to Solaris Studio 12.3 2013-09-21 timespec: use the new TIMESPEC_RESOLUTION elsewhere * configure.ac (WERROR_CFLAGS): Omit -fdiagnostics-show-option and -funit-at-a-time, since manywarnings does that for us now.

* Simplify EMACS_TIME-related code.Paul Eggert2013-08-271-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This portability layer is no longer needed, since Emacs has been using struct timespec as a portability layer for some time. Merge from gnulib, incorporating: 2013-08-27 timespec: new convenience constants and function * src/atimer.h, src/buffer.h, src/dispextern.h, src/xgselect.h: Include <time.h> rather than "systime.h"; that's all that's needed now. * src/dispnew.c: Include <timespec.h> rather than "systime.h"; that's all that's needed now. * src/systime.h (EMACS_TIME): Remove. All uses changed to struct timespec. (EMACS_TIME_RESOLUTION): Remove. All uses changed to TIMESPEC_RESOLUTION. (LOG10_EMACS_TIME_RESOLUTION): Remove. All uses changed to LOG10_TIMESPEC_RESOLUTION. (EMACS_SECS, emacs_secs_addr): Remove. All uses changed to tv_sec. (EMACS_NSECS): Remove. All uses changed to tv_nsec. (make_emacs_time): Remove. All used changed to make_timespec. (invalid_timespec): Rename from invalid_emacs_time. All uses changed. (current_timespec): Rename from current_emacs_time. All uses changed. (add_emacs_time): Remove. All uses changed to timespec_add. (sub_emacs_time): Remove. All uses change dot timespec_sub. (EMACS_TIME_SIGN): Remove. All uses changed to timespec_sign. (timespec_valid_p): Rename from EMACS_TIME_VALID_P. All uses changed. (EMACS_TIME_FROM_DOUBLE): Remove. All uses changed to dtotimespec. (EMACS_TIME_TO_DOUBLE): Remove. All uses changed to timespectod. (current_timespec): Rename from current_emacs_time. All uses changed. (EMACS_TIME_EQ, EMACS_TIME_LT, EMACS_TIME_LE): Remove. All uses changed to timespec_cmp. * src/xgselect.c: Include <timespec.h>, since our .h files don't.
* Merge from gnulib.Paul Eggert2013-08-112-7/+7
| | | | | | This incorporates: 2013-08-11 fpending: port to recent Cygwin change to stdio_ext.h 2013-08-10 sys_time: port to OpenBSD
* Fix some minor races in hosts lacking mkostemp.Paul Eggert2013-08-045-1/+474
| | | | | | | | | | | | | | | | | | | | | | 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 Eggert2013-07-094-9/+87
| | | | | | | | | | * 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 Eggert2013-07-092-56/+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.
* Try to fix FreeBSD 9.1 porting problem.Paul Eggert2013-07-072-62/+89
| | | | | | | This incorporates the following merge from gnulib: 2013-07-07 stdalign, verify: port to FreeBSD 9.1, to C11, and to C++11 Fixes: debbugs:14812
* Make file descriptors close-on-exec when possible.Paul Eggert2013-07-074-3/+595
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
