While we don't need to put docstrings of .elc files into etc/DOC,
we still need to put those of `loaddefs.el` there since we don't have
a "dynamic docstring" feature for the non-compiled files and keeping
the actual docstrings in the heap would be prohibitive.

Since the location of those files changes between build time and
installation time, this requires to tweak the file name used in those
(#$ . NNN) references during the dump so they don't hardcode the build
directory. We do it in the same way as was already done for those
same file names in `load-history`, except we convert them back to
absolute file names more lazily (i.e. when fetching the actual
docstring rather than at startup), which requires remembering the
`lisp-dir` computed at startup in the new `lisp-directory` variable.
* src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more.
* src/lread.c (Fload): Use relative file names for `load-file-name`
when preloading for the dump, like we already did for `current-load-list`.

(request_sigio, unrequest_sigio)
(emacs_sigaction_init): Also handle SIGPOLLs.
(init_sys_modes): Disable TCXONC usage on Haiku, as it
doesn't have any ttys other than pseudo ttys, which don't
support C-s/C-q flow control, and causes compiler warnings.
(speeds): Disable high speeds if HAVE_TINY_SPEED_T.
* src/termhooks.h (enum output_method): Add output_haiku.

(longopts): New option.
(decode_options): Decode the new option.
(print_help_and_exit): Document the new option.
(main): Use the new option.
* lib-src/ntlib.c (_GL_ATTRIBUTE_MALLOC)
(_GL_ATTRIBUTE_DEALLOC_FREE): Define to avoid compilation errors
with MinGW64 GCC 11. Suggested by Andy Moreton
<andrewjmoreton@gmail.com>. Do not merge to master.
On some systems, process startup calls prctl(PR_CAPBSET_READ) via
'cap_get_bound'. We can just return EINVAL.
* lib-src/seccomp-filter.c (main): Add a rule for
prctl(PR_CAPBSET_READ, ...).
This is a minor bugfix cleanup (Bug#33847#161).
* lib-src/emacsclient.c: Move "#include <acl.h>" to inside
"#ifdef SOCKETS_IN_FILE_SYSTEM", which is more accurate
and simpler than having a separate "#ifndef WINDOWSNT".
(O_PATH): Likewise.
* admin/merge-gnulib (GNULIB_MODULES): Add file-has-acl.
* lib/file-has-acl.c: New file, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib-src/emacsclient.c: Include acl.h, for file_has_acl.
(O_PATH): Default to O_SEARCH, which is good enough here.
(union local_sockaddr): New type.
(socket_status): Remove, replacing with ...
(connect_socket): New function. All callers changed.
This function checks for ownership and permissions issues with the
parent directory of the socket file, instead of checking the
owner of the socket (which does not help security).
(socknamesize): Move to file scope.
(local_sockname): New arg S. No need to pass socknamesize.
UID arg is now uid_t. All callers changed. Get file descriptor
of parent directory of socket, to foil some symlink attacks.
Do not follow symlinks to that directory.
(set_local_socket): Create the socket here instead of on
each attempt to connect it. Fall back from XDG_RUNTIME_DIR
to /tmp only if the former fails due to ENOENT. Adjust
permission-failure diagnostic to match changed behavior.
This addresses Bug#33847, which complained about emacsclient in a
safer XDG environment not connecting to an Emacs server running in
a less-safe enviroment outside XDG. The patch fixes a
longstanding issue with emacsclient permission checking.
It’s ineffective to look at the permission of the socket file
itself; on some platforms, these permissions are ignored anyway.
What matters are the permissions on the parent directory of the
socket file, as these are what make symlink attacks possible.
Change the permissions check accordingly, and also refuse to
follow symlinks to that parent directory. These changes make it
OK for emacsclient to fall back from XDG_RUNTIME_DIR to the
traditionally less-safe /tmp/emacsNNNN directories, since /tmp is
universally sticky nowadays.
* lib-src/etags.c (regexp): Omit member force_explicit_name,
since it’s always true. All uses removed. This lets us
remove calls to strlen (name) where GCC isn’t smart enough
to deduce that name must be nonnull.
* lib-src/movemail.c (main): Fix bug that could cause
link (tempname, NULL) to be called.
* src/emacs.c (argmatch): Break check into two ‘if’s,
since GCC doesn’t seem to be smart enough to check the single ‘if’.
* src/gtkutil.c (xg_update_menu_item): Fix bug where strcmp
could be given a NULL arg.
* src/xfont.c (xfont_list_family): Use nonnull value for dummy
initial value.
Correct the previous fix (did not correctly handle qualified types).
Also fix the following issues:
- remove module name (+ dot) from tags, as prefixing module name is
often inconsistent in code and may cause tags to be too specific.
- now tag 0-arity predicates and functions (':- func foo_14.')
- now tag one-word declarations (':- interface.')
* lib-src/etags.c (mercury_pr): Pass the correct NAME and NAMELEN
arguments to 'make_tag'.
(mercury_decl): Return more information about the declaration or
definition it finds. This allows mercury_pr to be smarter.
(Bug#47408)
The previous lack of support was due to incorrect calls to 'make_tag'
in 'mercury_pr', which caused 'pfnote' to refrain from adding Mercury
tags to the list of recorded tags.
* lib-src/etags.c (mercury_pr): Pass the correct NAME and NAMELEN
arguments to 'make_tag'.
* test/manual/etags/CTAGS.good: Adjust to the above change.
Tag declarations starting lines with ':-'.
By default, all declarations are tagged. Optionally, first
predicate or functions in clauses can be tagged as in Prolog
support using '--declarations'. (Bug#47408).
* lib-src/etags.c (test_objc_is_mercury, Mercury_functions)
(mercury_skip_comment, mercury_decl, mercury_pr):
Implement Mercury support. As Mercury and Objective-C have
the same file extension .m, a heuristic test tries to detect
the language.
* doc/man/etags.1: Document the change. Add Mercury-specific
behavior for '--declarations'. This option tags first
predicates or functions in clauses in addition to declarations.
* lib-src/etags.c (Rust_functions): New function to make tags for rust
files.
(Rust_help, Rust_suffixes): New constant.
* doc/emacs/maintaining.texi (Tag Syntax): Add Rust item.
* doc/man/etags.1: Add Rust (bug#46055).
Casting NULL is not a constant expression (Bug#47951).
* lib-src/seccomp-filter.c (main): Turn check for null pointer
representation into a runtime assertion.
If we're missing SECCOMP_SET_MODE_FILTER, the seccomp-filter build
fails. Reuse the existing HAVE_SECCOMP configuration variable, which
checks for these macros.
* configure.ac (HAVE_SECCOMP): Substitute in Makefile.in.
* lib-src/Makefile.in (HAVE_SECCOMP): New variable.
(SECCOMP_FILTER): Define only if HAVE_SECCOMP.
This is useful when starting Emacs with a Seccomp filter enabled,
e.g. using 'bwrap'.
* lib-src/seccomp-filter.c (main): Generate new Seccomp files.
* lib-src/Makefile.in (all)
(seccomp-filter.bpf seccomp-filter.pfc seccomp-filter-exec.bpf
seccomp-filter-exec.pfc): Generate new Seccomp files.
* .gitignore: Ignore new Seccomp files.
* test/src/emacs-tests.el (emacs-tests/bwrap/allows-stdout): New unit
test.
Only Linux 4.14 and later contain the required support for
SECCOMP_RET_KILL_PROCESS.
* lib-src/Makefile.in (SECCOMP_FILTER): Define only if we run at least
Linux 4.14.
We need at list version 2.4.0 of libseccomp for seccomp-filter.c to
build cleanly.
* configure.ac: Use pkg-config to check for libseccomp.
* lib-src/Makefile.in (HAVE_LIBSECCOMP, LIBSECCOMP_LIBS)
(LIBSECCOMP_CFLAGS): New variables.
(SECCOMP_FILTER, seccomp-filter$(EXEEXT)): Use them.
The seccomp filters are always architecture-specific, and
seccomp-filter.c right now only supports x86-64.
* lib-src/Makefile.in (SECCOMP_FILTER): New variable.
(DONT_INSTALL, all, seccomp-filter$(EXEEXT)): Use it.
The binary uses the 'seccomp' helper library. The library isn't
needed to load the generated Secure Computing filter.
* configure.ac: Check for 'seccomp' header and library.
* lib-src/seccomp-filter.c: New helper binary to generate a generic
Secure Computing filter for GNU/Linux.
* lib-src/Makefile.in (DONT_INSTALL): Add 'seccomp-filter' helper
binary if possible.
(all): Add Secure Computing filter file if possible.
(seccomp-filter$(EXEEXT)): Compile helper binary.
(seccomp-filter.bpf seccomp-filter.pfc): Generate filter files.
* test/src/emacs-tests.el (emacs-tests/seccomp/allows-stdout)
(emacs-tests/seccomp/forbids-subprocess): New unit tests.
* test/Makefile.in (src/emacs-tests.log): Add dependency on the helper
binary.
* configure.ac: Instead of AC_CHECK_HEADER, use AC_COMPILE_IFELSE
with X11/Intrinsic.h when checking for X11/extensions/Xrender.h.
This suppresses a bogus "report a bug to bug-gnu-emacs" diagnostic
from 'configure' in Solaris 10.
(SETUP_SLAVE_PTY): Adjust to recent renaming of forkin to
std_in in callproc.c. Needed on Solaris and Unixware.
* lib-src/Makefile.in (LIB_GETRANDOM, LIBS_ETAGS): New vars,
needed because on Solaris 10 the Gnulib tempname module now needs
the -lrt library for clock_gettime. Throw in the LIB_GETRANDOM
stuff too while we’re at it; from getrandom.m4 it seems to be
needed for MingW.
(LIBS_MOVE, etags_libs): Use them.
* src/callproc.c [SETUP_SLAVE_PTY]: Include sys/stream.h
and sys/stropts.h, for SETUP_SLAVE_PTY’s definiens.
* src/process.c [NEED_BSDTTY]: Don’t include bsdtty.h; hasn’t been
needed in years.
[USG5_4]: Don’t include sys/stream.h or sys/stropts.h; these
directives havbe been moved to callproc.c because the only use of
SETUP_SLAVE_PTY is there now.
The latest Gnulib merge brought in free-posix, which causes 'free'
to preserve errno. This lets us simplify some Emacs code that
calls 'free'.
* admin/merge-gnulib (GNULIB_MODULES): Add free-posix.
This module is pulled in by canonicalize-lgpl anyway,
so we might as well rely on it.
* lib-src/emacsclient.c (get_current_dir_name):
Sync better with src/sysdep.c.
* lib-src/etags.c (process_file_name, etags_mktmp):
* lib-src/update-game-score.c (unlock_file):
* src/fileio.c (file_accessible_directory_p):
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by assuming that 'free' preserves errno.
* src/alloc.c (malloc_unblock_input):
Preserve errno, so that xfree preserves errno.
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by using strdup instead of malloc+memcpy.
No need for realloc (and the old code leaked memory anyway on
failure); just use free+malloc.
* lib-src/etags.c: Set allocated and lastlen to zero, after
freeing last ptr in Erlang_functions to prevent dereferencing NULL
pointer (bug#45122).

Original problem report by N. Jackson in:
https://lists.gnu.org/r/emacs-devel/2020-03/msg00047.html
I found some other warnings when I used gcc, and fixed them
with this patch.
* lib-src/etags.c: Include verify.h.
(xnmalloc, xnrealloc): Tell the compiler that NITEMS is
nononnegative and ITEM_SIZE is positive.
* src/conf_post.h (__has_attribute_returns_nonnull)
(ATTRIBUTE_RETURNS_NONNULL): New macros.
* src/editfns.c (Fuser_full_name): Don’t assume Fuser_login_name
returns non-nil.
* src/intervals.c (rotate_right, rotate_left, update_interval):
* src/intervals.h (LENGTH, LEFT_TOTAL_LENGTH, RIGHT_TOTAL_LENGTH):
Use TOTAL_LENGTH0 or equivalent on intervals that might be null.
* src/intervals.h (TOTAL_LENGTH): Assume arg is nonnull.
(TOTAL_LENGTH0): New macro, with the old TOTAL_LENGTH meaning.
(make_interval, split_interval_right): Add ATTRIBUTE_RETURNS_NONNULL.
* src/pdumper.c (dump_check_dump_off): Now returns void, since
no caller uses the return value. Redo assert to pacify GCC.
(decode_emacs_reloc): Add a seemingly-random eassume to pacify GCC.
Ugly, and I suspect due to a bug in GCC.
* doc/emacs/custom.texi (Find Init): Update description of how Emacs
finds its init file directory and the interaction with
$XDG_CONFIG_HOME
(Early Init File): Correct XDG location of early-init.el
* etc/NEWS: Update description to make it clear the ~/.emacs.d is
preferred, even if the XDG location exists.
* lisp/startup.el: Prefer ~/.emacs.d even if the XDG location exists.
* lib-src/emacsclient.c (open_config): Prefer home directory the XDG
location.
etags had undefined behavior if input files, lines, tags, etc.,
had more than INT_MAX bytes. Clean up the usage of integer types
to fix the overflow errors I found.
* admin/merge-gnulib (GNULIB_MODULES): Add mempcpy.
* lib-src/etags.c: Include inttypes.h, intprops.h.
(memcpyz): New function. Use it to simplify several occurrences
of memcpy followed by storing a trailing '\0'.
(xnew): Use xnmalloc, to catch overflow on integer multiplication.
(xrnew): Change last arg to multiplier. The type is not needed.
All callers changed.
(node, lineno, charno, linecharno, invalidcharno, make_tag):
(pfnote, add_node, number_len, C_symtype, lbz, Makefile_targets)
(readline):
Use intmax_t for line numbers and character positions, instead of
int or long.
(linebuffer, make_tag, pfnote, total_size_of_entries, put_entry)
(in_word_set, C_symtype, token, cstack, pushclass_above):
(popclass_above, write_classname, consider_token, C_entries)
(Ruby_functions, Makefile_targets, Lua_functions, TeX_commands)
(TeX_decode_env, erlang_func, erlang_attribute, erlang_atom)
(substitute, regex_tag_multiline, nocase_tail, readline_interval)
(readline, savenstr, concat, etags_getcwd, relative_filename)
(linebuffer_setlen):
Use ptrdiff_t for object sizes, instead of int or long or unsigned
or size_t.
(write_classname, C_entries):
Avoid sprintf, as the result could exceed INT_MAX bytes
and then behavior goes haywire.
(main): Use int, instead of unsigned, for argv counts.
(get_language_from_filename): Use bool for boolean.
(Ruby_functions): Prefer strcpy to memcpy when copying "=".
(linebuffer_setlen): Use ‘if’ instead of ‘while’.
(memory_full, xnmalloc, xnrealloc): New functions.
(xmalloc): Use memory_full, and take a ptrdiff_t instead of a size_t.
(xrealloc): Remove; no longer needed.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/mempcpy.c, m4/mempcpy.m4: New files, copied from Gnulib.
This mostly changes http: to https: in URLs. It also updates
some URLs that have moved, removes some URLs that no longer
work, recommends against using procmail (procmail.org no
longer works), and removes some mentions of the
no-longer-existing Gmane, LPF and VTW.
It doesn't update all URLs, just the ones I had time for.
* GNUmakefile (help):
* admin/admin.el (manual-doctype-string):
* admin/charsets/Makefile.in (${charsetdir}/ALTERNATIVNYJ.map):
* admin/charsets/mapconv:
* lisp/net/soap-client.el (soap-create-envelope):
* lisp/org/org.el (org-doi-server-url):
* lisp/textmodes/bibtex.el (bibtex-generate-url-list):
Prefer https: to http: un URLs.
This reverts commit 6fe661342a.
The alternate editor may be Emacs, which is useful when you want to eval something in an existing Emacs (if it exists), or in a new Emacs if there's no server running.
NOTREACHED was designed for traditional lint decades ago,
and _Noreturn now normally subsumes its function.
In the one case in Emacs where NORETURN might help and _Noreturn does
not, check for NOTREACHED instead of assuming it.
* lib-src/etags.c (main):
* src/xterm.c (x_connection_closed):
Remove NOTREACHED after a call to a _Noreturn function, as NOTREACHED
is no longer needed there. Also, one of the NOTREACHEDs was
misplaced, which defeated traditional lint checking anyway.
* lib-src/pop.c (pop_getline): Redo so as to not need NOTREACHED.
* src/emacs.c (main): Use eassume (false) rather than NOTREACHED,
so that running with ENABLE_CHECKING catches any internal error
causing the toplevel Frecursive_edit to return.
* lib-src/emacsclient.c (open_config): New arg XDG, to respect
XDG_CONFIG_HOME, consistently with Emacs proper. Caller changed.
Use XDG convention if available, falling back on the old names
if not.
* lib-src/make-docfile.c (compare_globals):
Make symbols 1 through 4 be t, unbound, error, lambda.
This is in addition to symbol 0 being nil.
This change improved ‘make compile-always’ performance by 0.6%
on my platform.
* lib-src/emacsclient.c (fail): If the user said --eval, don't
pass those arguments to the alternate editor as file names.
Suggested by a patch from Scott Turner (bug#11474).
PATH_MAX is standardized, MAXPATHLEN is not.
Also, the Gnulib pathmax module fixes some rare bugs with PATH_MAX.
So prefer PATH_MAX to MAXPATHLEN unless we know the latter is
also correct (for some platform-specific code).
* admin/merge-gnulib (GNULIB_MODULES): Add pathmax.
This module was already present, as a dependency of canonicalize-lgpl,
but now Emacs is using it directly. Sort.
* lib-src/emacsclient.c: Include stdint.h, pathmax.h.
(get_current_dir_name): Sync to current src/sysdep.c.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/sysdep.c: Include pathmax.h.
(get_current_dir_name_or_unreachable):
Use PATH_MAX instead of MAXPATHLEN.
* lib-src/Makefile.in (etags_cflags): Remove.
All uses replaced by a simple ‘-o $@’.
(ebrowse${EXEEXT}, emacsclient${EXEEXT}, emacsclientw${EXEEXT}):
Omit -DVERSION= option.
* lib-src/ebrowse.c (VERSION):
* lib-src/emacsclient.c (VERSION):
* lib-src/etags.c (EMACS_NAME, VERSION): Remove.
All uses replaced by PACKAGE_NAME and PACKAGE_VERSION.
* lib-src/ebrowse.c (version):
* lib-src/etags.c (print_version):
Use fputs to output the version info, since that’s fputs_unlocked.
* lib-src/etags.c (PROGRAM_NAME): New macro.
(print_version): Use it.
* lib-src/make-fingerprint.c (main): Don't consider multiple
instances of the fingerprint to be an error, as this can
happen with clang and -flto. Instead, replace all instances
of the fingerprint. There is a tiny chance that this will
silently corrupt the Emacs executable.
This patch suggests that we should go back to fingerprinting
the inputs to the linker instead of its output, as the new
fingerprinting scheme is unnecessarily complicated and this
complexity reduces reliability. The old scheme (i.e., before
commit 2019-05-14T23:31:24Z!eggert@cs.ucla.edu) was simpler
and more portable and good enough, and it's looking like it
would be less trouble in practice than the new scheme.
* lib-src/etags.c [!DEBUG]: Do not define NDEBUG,
as that’s conf_post.h’s job now.
[NDEBUG]: Do not redefine ‘assert’, as that works around
ancient bugs (e.g., sunos4 pcc) that don’t matter any more,
as can be seen that other Emacs source files that successfully
use assert.h without this workaround.
This auxiliary executable was used by the old `profile.el` which later
inspired `elp.el`. It was made obsolete when Emacs acquired native timers.
* lib-src/Makefile.in (UTILITIES): Remove profile.
(profile${EXEEXT}): Delete rule.
Without this fix, linking emacsclient fails with ‘Undefined
symbol eaccess’ on Solaris 10 sparc.
* lib-src/Makefile.in (LIB_EACCESS): New macro.
(emacsclient${EXEEXT}, emacsclientw${EXEEXT}): Use it.
* lib-src/emacsclient.c (set_local_socket):
Use faccessat with AT_EACCESS instead of using euidaccess.
* admin/merge-gnulib, lib/gnulib.mk.in, m4/gnulib-comp.m4:
Revert previous change.
* lib-src/emacsclient.c (set_local_socket):
If there appears to be an XDG runtime directory for the user
but XDG_RUNTIME_DIR is unset, suggest setting it while warning
about potential security issues (Bug#35300).
* lib-src/make-fingerprint.c (fseeko) [WNDOWSNT]: Define to
fseeko64 for non-MinGW64 MinGW.
* lib-src/ntlib.c (stat): Fix calculation of file size.
(fstat): New function, a subset of src/w32.c:fstat. This is
needed because make-fingerprint.c now calls 'fstat', and the
MS version will fail to produce reliable results because
nt/inc/sys/stat.h redefines 'struct stat'.
* admin/merge-gnulib (GNULIB_MODULES): Add memmem-simple.
(AVOIDED_MODULES): Add memchr.
* configure.ac (HAVE_PDUMPER): AC_SUBST it, too, for use in makefiles.
* lib/Makefile.in (libgnu_a_OBJECTS): Add fingerprint.o.
* lib/fingerprint.c: New file.
* lib/memmem.c, lib/str-two-way.h, m4/memmem.m4: New files,
copied from Gnulib.
* lib/fingerprint.h: Rename from src/fingerprint.h.
* lib-src/make-fingerprint.c: Include limits.h, sys/stat.h,
fingerprint.h, intprops.h, min-max.h.
(SSIZE_MAX): New macro, if not already defined.
(main): Without -r, Replace the fingerprint in the input file
instead of generating a fingerprint.c.
* lib/Makefile.in (libgnu_a_OBJECTS): Add fingerprint.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/Makefile.in (HAVE_PDUMPER, MAKE_PDUMPER_FINGERPRINT):
New macros.
(temacs$(EXEEXT)): Use them to replace the fingerprint instead
of precalculating it.
(mostlyclean, ctagsfiles1): Do not worry about fingerprint.c.
Instead of building a file temacs.in used only to compute a
fingerprint, compute the fingerprint directly from the .o and
.a files that go into temacs.in. This speeds up the build by
avoiding the need to link temacs twice, once with a dummy
fingerprint.
* lib-src/make-fingerprint.c (main): No need to generate
a fingerprint file that includes config.h, now that fingerprint.c
depends on all the .o files.
* src/Makefile.in ($(libsrc)/make-fingerprint$(EXEEXT)):
Use the same rule as $(libsrc)/make-docfile$(EXEEXT).
* src/fingerprint-dummy.c: Remove.
* src/Makefile.in (${charsets}, $(libsrc)/make-docfile$(EXEEXT))
($(LIBEGNU_ARCHIVE), $(lwlibdir)/liblw.a, $(oldXMenudir)/libXMenu11.a)
(../config.status, ${ETAGS}, ../lisp/TAGS, $(lwlibdir)/TAGS)
($(lispsource)/loaddefs.el):
Prefer ‘$(MAKE) -C $(dir $@)’ to ‘${MAKE} -C SOMESTRING’ when
either will do, as the former is more regular and lets us
coalesce rules better.
(EMACS_DEPS_PRE, EMACS_DEPS_POST, BUILD_EMACS_PRE)
(BUILD_EMACS_POST, temacs.in$(EXEEXT)): Remove.
(FINGERPRINTED): New macro.
(fingerprint.c): Use it instead of temacs.in$(EXEEXT), to
avoid the need to build temacs.in at all.
(temacs$(EXEEXT)): No need to depend on other .o files now;
fingerprint.o is enough, since it depends on the rest.
Spell out what used to be in BUILD_EMACS_PRE and BUILD_EMACS_POST.
(mostlyclean): No need to remove temacs.in.
C11 doesn’t guarantee the existence of types like uint64_t,
so avoid these types in portable code, as it’s easy to do so.
There’s no need to avoid the types in w32-specific code,
since w32 is guaranteed to have them.
* lib-src/make-fingerprint.c (main):
* src/fingerprint-dummy.c:
* src/fingerprint.h:
* src/pdumper.c (dump_fingerprint, struct dump_header):
Prefer unsigned char to uint8_t in portable code, as either will do.
Put an "#include <config.h>" in fingerprint.c files, so
that the corresponding .o file is rebuilt after ./configure is run.
* lib-src/make-fingerprint.c (main):
Simplify loop.
* src/Makefile.in (fingerprint.c): Update atomically.
* src/pdumper.c: Omit unnecessary check that off_t is the same
size as int32_t or int64_t, as the code does not rely on this
assumption.
(dump_off): Use int_least32_t, not int32_t.
(struct dump_reloc): Use unsigned int, not uint32_t.
(dump_anonymous_allocate_w32, dump_anonymous_allocate_posix)
(dump_anonymous_allocate, dump_map_file_w32, dump_map_file_posix)
(dump_map_file:
Do the sanity checks at compile time, not at run-time, to avoid
usage of uint64_t etc. on non-w32 platforms.
This should help future improvements where these stats can be
bignums that do not fit into intmax_t.
* src/alloc.c (struct gcstat, gcstat): New type and static var,
to package up GC statistics into one C object. It replaces ...
(total_free_intervals, total_intervals, total_strings)
(total_free_strings, total_string_bytes, total_vectors)
(total_vector_slots, total_free_vector_slots): ... these
removed static vars. All uses changed.
(garbage_collect_1): Accept a struct gcstat *, not a void *
which was not used anymore anyway. Return a bool indicating
success, instead of a Lisp object. All callers changed.
(garbage_collect): New function. All C callers of
Fgarbage_collect changed to use it, since none of them use the
return value. Now, only Lisp code uses Fgarbage_collect.
(Fgarbage_collect): No longer noinline. Cons up the return
value here, not in garbage_collect_1.
Formerly they were fixnums, which led to problems when dealing
with values that might not fit on 32-bit platforms, such as
string-chars-consed or floats_consed. 64-bit counters should
be good enough for these (for a while, anyway...).
While we’re at it, fix some unlikely integer overflow bugs
that have been in the code for a while.

function. All uses changed.

* src/termcap.c: Include stdlib.h, for atoi.
Include intprops.h.
* src/window.c (sanitize_next_screen_context_lines): New function.

Use it to avoid signed integer overflow.

(set_interval_marked): new accessor routines. Use them
instead of raw GC access throughout.

* lib-src/emacsclient.c (process_grouping): New function.
(act_on_signals, main): Use it.
(main): Omit "Waiting for Emacs..." and later "\n" messages
if in background, since that messes up the screen.
Problem reported by Kaushal Modi in:
https://lists.gnu.org/r/emacs-devel/2018-12/msg00083.html
The tcdrain call replaced an fdatasync call which had no
effect on the tty, so removing it entirely shouldn’t cause
problems. The fdatasync call replaced an fsync call which
also had no effect on the tty, and the fsync call seems to be
badly-merged revenant of emacsclient’s old (circa 2004) way of
communicating to and from Emacs via FILE * streams, where
fsync was apparently needed when talking to sockets.
* lib-src/emacsclient.c [!DOS_NT]: Don’t include termios.h.
(flush_stdout): Remove. All callers removed.
(main): Do not drain the tty after "Waiting for Emacs..."
message. There should be no need to drain, and draining it
might send us a SIGTTOU. Do not fflush stdout just before
exiting, as exiting does that for us.
This ports to POSIXish platforms like macOS that lack SOCK_CLOEXEC.
Fix suggested by Eli Zaretskii in:
https://lists.gnu.org/r/emacs-devel/2018-12/msg00055.html
* lib-src/emacsclient.c (set_local_socket):
Don’t use SOCK_CLOEXEC; that’s cloexec_socket’s job.
Recent changes in sysdep.c and emacsclient unnecessarily
removed useful code from DOS_NT builds. This changeset
reinstates that code.
* nt/inc/ms-w32.h (tcdrain): Redirect to _commit.
(fdatasync): No need to redirect anymore.
* lib-src/emacsclient.c (flush_stdout): Don't avoid calling
tcdrain on DOS_NT platforms.
* src/sysdep.c (reset_sys_modes): Don't ifdef away the call to
tcdrain on DOS_NT platforms.
fdatasync is for storage devices, not ttys.
* admin/merge-gnulib (GNULIB_MODULES): Remove fdatasync.
* lib/fdatasync.c, m4/fdatasync.m4: Remove.
* lib-src/Makefile.in (LIB_FDATASYNC):
* src/Makefile.in (LIB_FDATASYNC):
Remove. All uses removed.
* lib-src/emacsclient.c [!DOS_NT]:
Include <termios.h>, for tcdrain.
* lib-src/emacsclient.c (flush_stdout):
* src/sysdep.c (reset_sys_modes): On ttys, use tcdrain instead
of fdatasync (except don’t use either function if DOS_NT).
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib-src/emacsclient.c (socket_status): New arg UID.
All uses changed.
(set_local_socket): Don’t create the unbound socket unless the
initial sanity checks on the socket file succeed; this
simplifies cleaning it up. Check socket ownership again
after connecting, to fix a race (Bug#33366).
* lib-src/emacsclient.c: Disable -Wformat-truncation=2,
to avoid false alarms about the new snprintf calls.
(local_sockname): New function.
(set_local_socket): Use it. Prefer XDG_RUNTIME_DIR (if set)
for location of socket directory. Avoid unnecessary memory
allocation by using snprintf to destination.
* lisp/server.el (server-socket-dir): Prefer XDG_RUNTIME_DIR if set.
* configure.ac (HAVE_INET_SOCKETS): Remove.
* lib-src/emacsclient.c: Simplify by assuming HAVE_SOCKETS and
HAVE_INET_SOCKETS, which are always true nowadays, except perhaps
for MS-DOS and if so this program shouldn’t be built there anyway.
Don’t bother including sys/types.h, as it’s not needed on modern
systems (and syswait.h does it for us anyway).
(main): Simplify by assuming SIGSTOP (which is always defined
if SIGCONT is), and by assuming HAVE_SOCKETS && HAVE_INET_SOCKETS.
* lib-src/emacsclient.c (SOCKETS_IN_FILE_SYSTEM): Rename from
NO_SOCKETS_IN_FILE_SYSTEM, with inverted sense. All uses changed.
All uses were of the form ‘#ifndef NO_SOCKETS_IN_FILE_SYSTEM’, and
it’s easier to read ‘#ifdef SOCKETS_IN_FILE_SYSTEM’.
Fix some longstanding race conditions due to emacsclient’s use of
‘signal’ instead of ‘sigaction’ and its use of nested signal
handlers. These races could cause premature exit or incorrect
commands sent to Emacs.
* lib-src/emacsclient.c (signal) [!WINDOWSNT]: Do not undef.
(emacs_socket): Remove this static variable. It is now a parameter.
(send_to_emacs): Do not exit merely because ‘send’ was interrupted.
Instead, act on the signal if possible, and then retry the ‘send’.
(pass_signal_to_emacs): Remove; now done by act_on_signals.
(reinstall_handler_if_needed, handle_sigttou, handle_sigwinch)
(install_handler): New functions.
(got_sigcont, got_sigtstp, got_sigttou, got_sigwinch):
New globals, used for more-portable signal handling.
(handle_sigcont, handle_sigtstp): Just set the static var; other
actions are now done later by act_on_signals.
(install_handler): New function that arranges for signals to
never be reset to default, on modern POSIX platforms.
This fixes some races.
(act_on_signals): New function. When acting on SIGCONT,
don’t bother calling getpgrp if tcgetpgrp fails.
(start_daemon_and_retry_set_socket): Return the socket
rather than setting a global variable. All uses changed.
(flush_stdout): New function that acts on signals received while
flushing.
(main): Use it. emacs_socket is now a local var.
Act on signals received during recv.
* lib-src/emacsclient.c (start_daemon_and_retry_set_socket):
If the execvp of Emacs fails exit instead of having the child
run on and do the work of the parent. Coalesce duplicate code.
* lib-src/emacsclient.c (set_tcp_socket, set_local_socket):
Close socket (instead of leaking it) when ‘connect’ fails.
(socket_status): Return errno if stat fails and -1 if we don’t own.
(set_local_socket): Simplify based on socket_status change.
* lib-src/emacsclient.c (get_server_config, set_tcp_socket)
(set_local_socket): Initialize any platform-specific extensions
of struct to zero, just in case.
(set_tcp_socket, set_local_socket): Don’t assume struct
layout details that POSIX does not specify.
Use union to sidestep some problems with strict aliasing.
Remove unnecessary casts.
* lib-src/emacsclient.c: Include <intprops.h>.
(EXTRA_SPACE): Remove; code no longer guesses this is enough.
(open_config): New function.
(get_server_config): Use it.
(set_local_socket): Compute upper bound of buffer size
instead of guessing via EXTRA_SPACE.
* lib-src/emacsclient.c (quote_argument):
Mention *DATA in comment so it’s clear DATA must be non-null.
(quote_argument, unquote_argument): Simplify.
(unquote_argument): Don’t crash if the string ends in "&".
* lib-src/emacsclient.c: Include <dosname.h>.
(file_name_absolute_p): Remove, as a code duplicate.
All uses replaced by IS_ABSOLUTE_FILE_NAME.
(set_local_socket): Don’t treat \ as a file name separator
on GNU and POSIX hosts.
* lib-src/emacsclient.c (nowait, quiet, suppress_output, eval, tty)
(decode_options, file_name_absolute_p, get_server_config)
(strprefix, find_tty, set_socket, main):
Use bool for boolean.
(create_frame): New static var, replacing the old current_frame
and with inverted sense, as this is clearer.
If the '--socket-name' argument is unspecified, the environment
variable 'EMACS_SOCKET_NAME' is now consulted with the same
semantics. This mirrors the behavior of the '--server-file' argument,
and allows for easier configuration of emacsclient when the socket is
in a location other than 'TMPDIR' or '/tmp'.
* emacsclient.c (set_socket): Add support for the
EMACS_SOCKET_NAME environment variable. (Bug#33095)
* misc.texi (emacsclient Options):
* emacsclient.1: Document the EMACS_SOCKET_NAME environment
variable.
* etc/NEWS: Announce the new feature.
Copyright-paperwork-exempt: yes
This change was motivated by the desire to remove the weird
dependency of lib-src/profile.o on src/systime.h. profile.c
included systime.h only for current_timespec, and this
inclusion required systime.h to have #ifdef emacs in multiple
places and complicated further changes I have in mind.
The current_timespec decl belongs in timespec.h anyway,
and the main effect of this change is to move it there.
* lib-src/profile.c (INLINE): Remove.
Include timespec.h, not systime.h.
* lib/gettime.c (gettime): Prefer clock_gettime to nanotime,
and don’t worry about it failing on a CLOCK_REALTIME arg.
POSIX requires it to succeed and I don’t know of any
counterexamples where the fallbacks would work.
(current_timespec): Move here from src/systime.h.
Nowadays it seems to be better to not have this function
be inline.
* lib/timespec.h: Include arg-nonnull.h.
(current_timespec): New declaration.
(gettime, settime): Declare args to be nonnull.
* lib/gettime.c, lib/timespec.h: Copy from Gnulib.
* src/systime.h: Simplify by assuming ‘emacs’ is defined,
which it always is now.
(current_timespec): Move to lib/timespec.h.
Adjust to lib/timespec.h’s renaming of TIMESPEC_RESOLUTION and
LOG10_TIMESPEC_RESOLUTION to TIMESPEC_HZ and
LOG10_TIMESPEC_HZ. The old names were misnomers.
All uses changed.
* configure.ac (GMP_OBJ): When building mini-gmp, compile
mini-gmp-emacs.c, not mini-gmp.c.
* lib-src/etags.c (NDEBUG): Don't attempt to redefine, in
case the builder compiles with -DNDEBUG.
* src/conf_post.h (NDEBUG) [!ENABLE_CHECKING && !NDEBUG]: Define.
This avoids bloat in mini-gmp-emacs.o.
* src/mini-gmp-emacs.c: New file, which pacifies --enable-gcc-warnings.

in INSIDE_EMACS value.
Emacs regular expressions forked from everyone else long ago.
This makes it official and should allow simplification later.
etags.c now uses the glibc regex API, falling back on a
Gnulib-supplied substitute lib/regex.c if necessary.
Emacs proper now uses its own regular expression module.
Although this patch may look dauntingly large, most of it
was generated automatically by admin/merge-gnulib
and contains an exact copy of the glibc regex source,
and the by-hand changes do not grow the Emacs source code.
* admin/merge-gnulib (GNULIB_MODULES): Add regex.
(AVOIDED_MODULES): Add btowc, langinfo, lock, mbrtowc, mbsinit,
nl_langinfo, wchar, wcrtomb, wctype-h.
* lib-src/Makefile.in (regex-emacs.o): Remove; Gnulib does it now.
(etags_deps, etags_libs): Remove regex-emacs.o.
* lib-src/etags.c: Go back to including regex.h.
(add_regex): Use unsigned char translation array,
since glibc regex requires that.
* lib/Makefile.in (not_emacs_OBJECTS, for_emacs_OBJECTS): New macros.
(libegnu_a_OBJECTS): Use them, to avoid building e-regex.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/regcomp.c, lib/regex.c, lib/regex.h, lib/regex_internal.c:
* lib/regex_internal.h, lib/regexec.c, m4/builtin-expect.m4:
* m4/eealloc.m4, m4/glibc21.m4, m4/mbstate_t.m4, m4/regex.m4:
New files, copied from Gnulib.
* src/regex-emacs.h, src/conf_post.h:
(RE_TRANSLATE_TYPE, RE_TRANSLATE, RE_TRANSLATE_P):
Move from src/conf_post.h to src/regex-emacs.h,
so that they don’t interfere with compiling lib/regex.c.
This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.
* src/regex-emacs.c: Rename from src/regex.c.
* src/regex-emacs.h: Rename from src/regex.h. All uses changed.
* test/src/regex-emacs-tests.el: Rename from test/src/regex-tests.el.
