* configure.ac (difftime): Remove.
* lib/update-game-score.c (difftime) [!HAVE_DIFFTIME]: Remove.
(read_score) [HAVE_GETDELIM]: Don't access uninitialized storage.
(read_scores, write_scores): Check for fclose failure.
(write_scores): Use fchmod, not chmod, to avoid a race.
(lock_file): Fix test for out-of-date lock file; it was reversed.
Use ordinary subtraction rather than difftime; since we're already
assuming POSIX we don't need to worry about the possibility of
time_t being a magic cookie.
configure.ac: Read $srcdir/nt/mingw-cfg.site when $MSYSTEM is
"MINGW64" as well.
nt/inc/ms-w32.h (pthread_sigmask): Undefine if defined, for MinGW64.
src/unexw32.c (_start) [__MINGW64__]: Define to __start.
Problem and proposed patch reported by Ulrich Mueller;
this patch uses a somewhat-different approach.
* configure.ac (SETFATTR): New variable.
* src/Makefile.in (SETFATTR): New macro.
(temacs$(EXEEXT)): Use it.
configure.ac (canonical, C_SWITCH_SYSTEM): Support a 64-bit
MinGW64 build on MS-Windows.
nt/inc/ms-w32.h (sys_kill): Fix prototype.
src/w32term.c (w32_initialize): Use LCID and LOWORD.
src/w32proc.c (create_child): Use pid_t for 5th argument.
(IsValidLocale): Don't provide prototype for MinGW64.
(Fw32_get_valid_keyboard_layouts, Fw32_get_keyboard_layout)
(Fw32_set_keyboard_layout): Use HKL and HIWORD/LOWORD.
src/w32heap.c (allocate_heap) [_WIN64]: Use "ull", not "i64", which
MinGW64 doesn't support.
src/lisp.h (EMACS_INT) [_WIN64]: Define for the MinGW64 build.
* configure.ac (xcsdkdir): Default to empty.
(XCRUN): Don't require Darwin for xcrun. Move xcrun checking to
just before AM_INIT_AUTOMAKE, to make the dependency between it
and automake clearer.
(CC): Don't use AC_PROG_CC twice; only the first use expands to the
shell code that is wanted, which breaks 'configure' on non-Darwin
platforms. Instead, fix CC by hand if it's not found.
On my Fedora 19 platform the core dumps were so big that
my desktop became nearly catatonic.
* configure.ac: Check whether addresses are sanitized.
(CANNOT_DUMP): Warn if addresses are sanitized and not CANNOT_DUMP.
(DOUG_LEA_MALLOC): Do not define if addresses are sanitized.
(SYSTEM_MALLOC): Define if addresses are sanitized.
* src/alloc.c (no_sanitize_memcpy) [MAX_SAVE_STACK > 0]: New function.
(Fgarbage_collect) [MAX_SAVE_STACK > 0]: Use it.
(USE_ALIGNED_MALLOC): Do not define if addresses are sanitized.
(mark_memory): Use ATTRIBUTE_NO_SANITIZE_ADDRESS rather than
a clang-only syntax.
* src/conf_post.h (__has_feature): New macro, if not already defined.
(ADDRESS_SANITIZER, ADDRESS_SANITIZER_WORKAROUND)
(ATTRIBUTE_NO_SANITIZE_ADDRESS): New macros.
* configure.ac: Work even if libgif etc. are missing. Emacs works
without these libraries even if its default GUI is harmed, so they
are not strictly necessary. Another possibility would be to
disable X11 if these libraries are missing. The point is that a
plain 'configure' should not fail on platforms like Solaris 11
where one or more image libraries are not installed by default.
This scorches the earth and waits for spring;
see Ted Zlatanov and Stefan Monnier in
<http://lists.gnu.org/archive/html/emacs-devel/2013-12/msg00323.html>.
* configure.ac (with_openssl_default, HAVE_LIB_CRYPTO): Remove.
Do not say whether Emacs is configured to use a crypto library,
since it's no longer an option.
(gl_CRYPTO_CHECK): Define a dummy.
* lib/gl_openssl.h, m4/gl-openssl.m4: Remove.
* admin/merge-gnulib: Remove lib/gl_openssh.h and m4/gl-openssl.m4.
* src/Makefile.in (LIB_CRYPTO): Remove.
(LIBES): Don't use it.
Move -DGDK_DISABLE_DEPRECATION_WARNINGS out of the command line
and into config.h, to shorten the command line when doing 'make'.
Don't AC_SUBST GTK_CFLAGS, as this is not needed.
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:

* configure.ac (--without-all): Set with_openssl_default too.
Use gl_SET_CRYPTO_CHECK_DEFAULT to default to 'auto'.

(LIBXMENU_DIR, LIBXMENU_BASE): New macros.
(LIBXMENU): Use them.
(temacs$(EXEEXT)): Depend on $(LIBXMENU), not stamp-oldxmenu.
($(lwlibdir)/liblw.a, $(oldXMenudir)/libXMenu11.a, FORCE): New targets.
(boostrap-clean): No need to remove stamp-oldxmenu.
* src/lisp.h (DEBUGGER_SEES_C_MACROS): Likewise.
It apparently doesn't work for GCC 3, and I suppose it's more
trouble than it's worth to worry about this.
* src/lisp.h (DEFINE_GDB_SYMBOL_BEGIN, DEFINE_GDB_SYMBOL_END):
Define to empty if DEBUGGER_SEES_C_MACROS is defined.

(Ffillarray): Prefer tail call.
* src/data.c (bool_vector_binop_driver): Don't assume bit vectors always
contain at least one word.

* src/fns.c (Fcopy_sequence):
Simplify and tune.
* src/lisp.h (bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD):

(posix_memalign): Test for existence only if !GMALLOC_OBJ and
not darwin and !aligned_alloc.

(USE_POSIX_MEMALIGN): Remove. All uses replaced with USE_ALIGNED_ALLOC,
and use of posix_memalign replaced with aligned_alloc.
(aligned_alloc): New function, defined or declared as needed.
* src/conf_post.h (HAVE_POSIX_MEMALIGN) [DARWIN_OS]:
Don't undef; configure.ac now does this.
* src/gmalloc.c (aligned_alloc) [MSDOS]: New decl.
(calloc, aligned_alloc): Check for integer overflow.
(aligned_alloc): Rename from memalign. All uses changed.
(memalign): New function, an alias for aligned_alloc.
* configure.ac (BITSIZEOF_SIZE_T, SIZEOF_SIZE_T):
New symbols to configure.
* src/alloc.c (ROUNDUP): Move here from lisp.h, since it's now used
only in this file. Use a more-efficient implementation if the
second argument is a power of 2.
(ALIGN): Rewrite in terms of ROUNDUP. Make it a function.
Remove no-longer-necessary compile-time checks.
(bool_vector_exact_payload_bytes): New function.
(bool_vector_payload_bytes): Remove 2nd arg; callers that need
exact payload changed to call the new function. Do not assume
that the arg or result fits in ptrdiff_t.
(bool_vector_fill): New function.
(Fmake_bool_vector): Use it. Don't assume bit counts fit
in ptrdiff_t.
(vroundup_ct): Don't assume arg fits in size_t.

(Ffillarray): Use bool_vector_fill.
(mapcar1): Use bool_vector_ref.
(sxhash_bool_vector): Hash words, not bytes.
* src/lisp.h (BOOL_VECTOR_BITS_PER_CHAR): Now a macro as well as
a constant, since it's now used in #if.
(bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD): Fall back on
unsigned char on unusual architectures, so that we no longer
assume that the number of bits per bits_word is a power of two or
is a multiple of 8 or of CHAR_BIT.
(Qt): Add forward decl.
(struct Lisp_Bool_Vector): Don't assume EMACS_INT is aligned
at least as strictly as bits_word.

is a unibyte string, convert NAME to a unibyte string to ensure
that the result is also a unibyte string.
src/emacs.c (init_cmdargs): Use build_unibyte_string to make sure we
create unibyte strings from default paths and directory/file
names.
src/coding.h (ENCODE_FILE): Do not attempt to encode a unibyte
string.
src/callproc.c (init_callproc): Use build_unibyte_string to make
sure we create unibyte strings from default paths and
directory/file names.
src/buffer.c (init_buffer): Don't store default-directory of
*scratch* in multibyte form. The original problem which led to
that is described in
http://lists.gnu.org/archive/html/emacs-pretest-bug/2004-11/msg00532.html,
but it was solved long ago.
lisp/startup.el (normal-top-level): Move setting eol-mnemonic-unix,
eol-mnemonic-mac, eol-mnemonic-dos, and also setup of the locale
environment and decoding all of the default-directory's to here
from command-line.
(command-line): Decode also argv[0].
lisp/loadup.el: Error out if default-directory is a multibyte string
when we are dumping.
lisp/Makefile.in (emacs): Don't set LC_ALL=C.
leim/Makefile.in (RUN_EMACS): Don't set LC_ALL=C.
configure.ac: Don't disallow builds in non-ASCII directories.
* doc/emacs/ack.texi (Acknowledgments): Comment out old alpha stuff.
* lisp/emacs-lisp/authors.el (authors-fixed-entries):
Comment out old alpha stuff.
Fixes: debbugs:15601
* configure.ac: Define HAVE_GNUTLS3 if GnuTLS v3 is found.
* src/gnutls.c (gnutls_audit_log_function): Add function for GnuTLS
audit logging (only used with GnuTLS 3.x) and enable it.
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.
* configure.ac: With clang, check for and use -Wno-switch,
-Wno-tautological-constant-out-of-range-compare and -Wno-pointer-sign.
* conf_post.h(assume): Use __builtin_unreachable for clang.
* src/filelock.c (lock_file_1): Rearrange to remove compiler warning
about excess arguments to snprintf.
warings.
* alloc.c (USE_VALGRIND): New macro; on by default

(init_alloc) [USE_VALGRIND]: Initialize valgrind_p.
require glib >= 2.28 for GTK3, glib >= 2.10 for GTK2,
glib >= 2.26 for GSettings and glib >= 2.7.0 for GConf, so
suitable glib should provide g_type_init unconditionally.
* src/image.c (fn_g_type_init) [WINDOWSNT]: Define and load
only if Glib < 2.36.0.
(fn_g_type_init) [!WINDOWSNT]: Define only if Glib < 2.36.0.
* src/xsettings.c (init_gconf, init_gsettings): Do not check
for g_type_init.
* configure.ac: Add check for OSX 10.5, required for macfont.o.
* etc/NEWS: Mention the macfont backend.
* src/Makefile.in (NS_OBJ, SOME_MACHINE_OBJECTS): Add macfont.o.
* src/font.c (syms_of_font): Call syms_of_macfont.

(Fns_popup_font_panel): Get font from macfont driver, if used.
* src/nsfont.m (ns_tmp_flags, ns_tmp_font): Remove.
(nsfont_open): Set font driver type.
Set font->ascent and font->descent. Figure out font instead of
ns_tmp_font, and flags instead of ns_tmp_flags.
Fix indentation. Remove call to ns_draw_text_decoration,
moved to nsterm.
* src/nsterm.m: Include macfont.h.
(ns_tmp_flags, ns_tmp_font): Remove.
(ns_compute_glyph_string_overhangs): Check for driver Qns.

getiing font.
* src/nsterm.h (FONT_DESCENT, FONT_ASCENT): Define to (f)->ascent and
(f)->descent.
* configure.ac (LDFLAGS_NOCOMBRELOC): New variable.
(LDFLAGS): Move nocombreloc option from here...
(LD_SWITCH_SYSTEM_TEMACS): ... to here.
This is an essential option that should not be in LDFLAGS,
because the user may override that at build time; eg
http://bugs.debian.org/684788. temacs is the only thing
that actually needs this option; this is where it was orginally:
http://lists.gnu.org/archive/html/emacs-pretest-bug/2004-03/msg00170.html
* configure.ac (WERROR_CFLAGS): Omit redundant use of
-Wmissing-field-initializers, -Wswitch, -Wtype-limits,
-Wunused-parameter. If there is no window system, also omit
-Wsuggest-attribute=const and -Wsuggest-attribute=noreturn; this
is needed for Fedora 19.
* src/gfilenotify.c (globals_of_gfilenotify):
Call g_type_init only if using an older glib version that needs it.
* configure.ac: If both --without-x and --enable-gcc-warnings are
specified, use -Wno-unused-variable, -Wno-unused-but-set-variable
and -Wno-unused-but-set-parameter.
* src/font.c (register_font_driver): Move check under HAVE_WINDOW_SYSTEM.
* src/font.h (struct font_driver): Move draw, get_bitmap and free_bitmap
members under HAVE_WINDOW_SYSTEM.
* src/keyboard.c (make_lispy_focus_out): Likewise.
(record_menu_key): Move under HAVE_MENUS.

and CLEAR_FONT_TABLE_NFONTS.
(set_font_frame_param, clear_face_gcs, realize_non_ascii_face):
Declare only if HAVE_WINDOW_SYSTEM.
(lface_same_font_attributes_p, clear_face_gcs): Define only
if HAVE_WINDOW_SYSTEM.
* configure.ac (DOCMISC_W32): New var to replace DOCMISC_*_W32.
* doc/misc/Makefile.in (DOCMISC_W32): New var to replace DOCMISC_*_W32.
(TARGETS): New intermediate variable.
(DVI_TARGETS, HTML_TARGETS, PDF_TARGETS, PS_TARGETS): Use it.
This improves on the patch already installed, by quoting options
that contain spaces and suchlike systematically, so that
EMACS_CONFIG_OPTIONS is no longer ambiguous when options contain
these characters.
Fixes: debbugs:13274
* configure.ac (PTY_OPEN): If posix_openpt with O_CLOEXEC fails
and reports EINVAL, try it again without O_CLOEXEC. This should
port PTY_OPEN to FreeBSD 9, which stupidly rejects O_CLOEXEC.
What were they thinking?
Fixes: debbugs:15129
configure.ac (HAVE_ZLIB): Don't use -lz on MinGW.
src/decompress.c <zlib_initialized> [WINDOWSNT]: New static variable.
(Fzlib_decompress_region) [WINDOWSNT]: Call init_zlib_functions if
not yet initialized.
configure.ac (LIBZ): Comment on w32 peculiarities regarding LIBZ.
src/decompress.c [WINDOWSNT]: Include windows.h and w32.h.
(DEF_ZLIB_FN, LOAD_ZLIB_FN) [WINDOWSNT]: New macros. Use them to
define static variables that are pointers to zlib functions to be
dynamically loaded.
(init_zlib_functions) [WINDOWSNT]: New function.
(fn_inflateInit2_, fn_inflate, fn_inflateEnd, fn_inflateInit2):
New macros.
(Fdecompress_gzipped_region, unwind_decompress): Use the fn_*
macros instead of invoking the zlib functions directly.
(syms_of_decompress): DEFSYM Qzlib_dll. Staticpro
Szlib_available_p.
lisp/term/w32-win.el (dynamic-library-alist): Add DLLs for zlib.
* configure.ac: Add --with-zlib option to 'configure', so that Emacs
can be built without zlib. Don't assume that -lz is needed on
non-PNG hosts. Mention zlib configuration status in 'configure' output.
lib-src/update-game-score.exe.manifest: New file.
lib-src/Makefile.in (UPDATE_MANIFEST): New variable.
(SCRIPTS): Add $(UPDATE_MANIFEST).
configure.ac: Define and substitute UPDATE_MANIFEST.
Gnulib's emulation of mkostemp doesn't have races that Emacs's does.
* configure.ac (mkostemp): Remove check for this function;
gnulib does the check now.
(mkstemp): Remove check for this no-longer-used function.
* lib/mkostemp.c, lib/secure_getenv.c, lib/tempname.c, lib/tempname.h:
* m4/mkostemp.m4, m4/secure_getenv.m4, m4/tempname.m4:
New files, copied from Gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add mkostemp.
* lib-src/movemail.c (main):
* lib-src/update-game-score.c (write_scores):
Use mkostemp (which now works on all platforms, due to changes
in the portability layer) rather than mktemp (which has a race)
or mkstemp (which we no longer bother with).
* src/callproc.c (create_temp_file):
* src/filelock.c (create_lock_file):
Assume mkostemp, since it's now provided by Gnulib.
Fixes: debbugs:15015
* configure.ac (etc, lisp): No need to create specially.
Configure already creates lisp when generating lisp/Makefile;
src/Makefile now creates etc when needed.
* src/Makefile.in ($(etc)/DOC, temacs$(EXEEXT)): Ensure etc/ exists.
* configure.ac (USE_NCURSES): New symbol.
* src/dispnew.c (init_display): Depend on USE_NCURSES, not GNU_LINUX,
to decide whether ncurses is being used. Without this change,
GCC complains about tgetent not being declared, on a system
that has tinfo installed but ncurses not installed.
* configure.ac (PTY_TTY_NAME_SPRINTF): Use PTY_NAME_SIZE,
not sizeof pty_name, since pty_name is now a pointer to the array.
* src/process.c (PTY_NAME_SIZE): New constant.
(pty_name): Remove static variable; it's now auto.
(allocate_pty): Define even if !HAVE_PTYS; that's simpler.
Take pty_name as an arg rather than using a static variable.
All callers changed.
(create_process): Recover pty_flag from process, not from volatile local.
(create_pty): Stay inside array even when pty allocation fails.
(Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.
* configure.ac (PTY_TTY_NAME_SPRINTF): Use emacs_close, not close.

* src/unexhp9k800.c, src/unexmacosx.c (unexec):
* src/callproc.c (Fcall_process_region):
Use emacs_close, not close.
* src/sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
New macro and function, which emulates the POSIX_CLOSE_RESTART macro
and posix_close function on current platforms (which all lack them).
(emacs_close): Use it. This should fix the races on GNU/Linux and
on AIX and on future platforms that support POSIX_CLOSE_RESTART,
and it should avoid closing random victim file descriptors on
other platforms.
Problem reported by T.V. Raman.
* configure.ac (accept4): New function to check for.
* src/process.c (close_on_exec, accept4, process_socket):
Define these if !HAVE_ACCEPT4, not if !SOCK_CLOEXEC.
Fixes: debbugs:14803
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/emacs.c (main) [!DOS_NT]:
* src/nsterm.m (ns_term_init):

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
* configure.ac: Leave GTK_OBJ and term_header alone if GTK 3
exists but cannot be compiled.
* src/xmenu.c (x_menu_wait_for_event) [!USE_GTK]:
* src/xterm.c (x_error_handler) [!USE_GTK]:
Do not use GTK 3.
* configure.ac (log2): Check for this function.
* doc/lispref/numbers.texi (Math Functions): Remove obsolete function log10.
* lisp/subr.el (log10): Move here from C code, and declare as obsolete.
All uses of (log10 X) replaced with (log X 10).
* src/floatfns.c (Flog) [HAVE_LOG2]: Use log2 if available and if the
base is 2; this is more accurate.
(Flog10): Move to Lisp (marked obsolete there).
In lisp.h, prefer functions to function-like macros, and
constants to object-like macros, when either will do. This:
. simplifies use, as there's no more need to worry about
arguments' side effects being evaluated multiple times.
. makes the code easier to debug on some platforms.
However, when using gcc -O0, keep using function-like macros
for a few critical operations, for performance reasons.
This sort of thing isn't needed with gcc -Og, but -Og
is a GCC 4.8 feature and isn't widely-enough available yet.
Also, move functions from lisp.h to individual modules when possible.
From a suggestion by Andreas Schwab in <http://bugs.gnu.org/11935#68>.
