(MAX_LFINFO): New top-level constant.
(lock_info_type): Remove members pid, boot_time. Add members at,
dot, colon. Change user member to be the entire buffer, not a
pointer. This allows us to handle the case where a foreign
pid or boot time exceeds the local range. All uses changed.
(LINKS_MIGHT_NOT_WORK): New constant.

Always use .#FILE (not .#-FILE) for the file lock,
even if it is a regular file.
(rename_lock_file): New function.
(create_lock_file): Use it.
(create_lock_file, read_lock_data):
Prefer a symbolic link for the lock file, falling back on a
regular file if symlinks don't work. Do not try to create
symlinks on MS-Windows, due to security hassles. Stick with
POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
link, rename, unlink, mkstemp) when creating locks, as a GNUish
host may be using a Windowsish file system, and cannot use
MS-Windows-only system calls. Fall back on mktemp if mkstemp
doesn't work. Don't fail merely because of a symlink-contents
length limit in the current file system; fall back on regular
files. Increase the symlink contents length limit to 8 KiB, this
should be big enough for any real use and doesn't crunch the
stack.
(create_lock_file, lock_file_1, read_lock_data):
Simplify allocation of lock file buffers now that they fit in 8 KiB.
(lock_file_1): Return error number, not bool. All callers changed.
(ELOOP): New macro, if not already defined.
(read_lock_data): Return size of lock file contents, not Lisp object.
All callers changed. Handle a race condition if some other process
replaces a regular-file lock with a symlink lock or vice versa,
while we're trying to read the lock.
(current_lock_owner): Parse contents more carefully, to help avoid
confusing a regular-file lock with some other application's use
of the file. Check for lock file contents being too long, or
not parsing correctly.
(current_lock_owner, lock_file):
Allow foreign pid and boot times that exceed the local range.
(current_lock_owner, lock_if_free, lock_file):
Simplify allocation of lock file contents.
* src/w32.c (sys_rename_replace): New function, containing most of
the contents of the old sys_rename.
(sys_rename): Use it.
(fchmod): New dummy function.
* src/w32.h (sys_rename_replace, fchmod): New decls.
Fixes: debbugs:13807
The old approach, which fell back on DIR/.#FILE.0 through
DIR/.#FILE.9, had race conditions that could not be easily fixed.
If DIR/.#FILE is a non-symlink file, Emacs now does not create a
lock file for DIR/FILE; that is, DIR/FILE is no longer partly
protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
because the locking mechanism was never reliable in that case).
This patch fixes this and other bugs discovered by a code
inspection that was prompted by
<http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
to avoid interoperability problems between the MS-Windows and
non-MS-Windows implementations. MS-Windows and non-MS-Windows
instances of Emacs now ignore each others' locks.
* etc/NEWS: Document this.
* src/filelock.c (defined_WINDOWSNT): New constant.
(MAKE_LOCK_NAME, fill_in_lock_file_name):
Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
regular files on MS-Windows hosts.
(MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
Use SAFE_ALLOCA to avoid problems with long file names.
(MAX_LFINFO): Now a local constant, not a global macro.
(IS_LOCK_FILE): Remove.
(lock_file_1): Don't inspect errno if symlink call succeeds;
that's not portable.
(lock_file): Document that this function can return if lock
creation fails.
Fixes: debbugs:13807
This is a followon simplification to the fix for Bug#13650.
* admin/CPP-DEFINES (DATA_START, ORDINARY_LINK): Remove.
* configure.ac (CRT_DIR, LIB_STANDARD, START_FILES, DATA_START)
(LD_FIRSTFLAG, ORDINARY_LINK, LIB_GCC): Remove.
(AC_CHECK_HEADERS_ONCE): Remove sys/resource.h, as it's
not always needed.
(HAVE_DATA_START): New macro.
* etc/PROBLEMS (LIBS_SYSTEM, LIBS_MACHINE, LIBS_STANDARD): Remove.
Remove legacy-systems section, as this stuff is no longer
applicable with current linking strategies.
* src/Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
(START_FILES): Remove. All uses removed.
(otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
(ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
(buildobj.h): Use it.
($(ALLOBJS)): Depend on globals.h.
(temacs$(EXEEXT)): Use $(ALLOBJS).
* src/autodeps.mk (ALLOBJS): Move to Makefile.in.
* src/deps.mk (vm-limit.o):
* src/makefile.w32-in ($(BLD)/vm-limit.$(O)):
Do not depend on mem-limits.h.
* src/emacs.c (__do_global_ctors, __do_global_ctors_aux)
(__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
[__GNUC__ && !ORDINARY_LINK]: Remove.
* src/mem-limits.h, src/pre-crt0.c: Remove.
* src/unexaix.c, src/unexcoff.c: Don't include mem-limits.h.
* src/unexcoff.c (etext): New decl.
(make_hdr): Use it instead of start_of_data.
* src/vm-limit.c: Move most of mem-limits.h's contents here.
(data_start): New decl. It's OK if this is approximate,
so simplify-away some unnecessary exactness.
(POINTER): Remove; all uses removed.
(data_space_start): Now char *, to avoid casts.
(exceeds_lisp_ptr): New function, replacing the old
EXCEEDS_LISP_PTR macro. All uses changed.
(check_memory_limits): Simplify and remove casts.
(start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
(memory_warnings): Use data_start instead of start_of_data.
Fixes: debbugs:13783
* make-dist: Only README files exist in lisp/ now, not README*.
* doc/misc/calc.texi (Help Commands): Mention etc/CALC-NEWS.
* etc/CALC-NEWS: Move here from lisp/calc/README, README.prev.
* lisp/calc/README, lisp/calc/README.prev: Rename/merge to etc/CALC-NEWS.
