to avoid potential buffer overflow issues on typical 64-bit hosts.
(whatlen_max): New static var.
(main): Avoid buffer overflow if subsidiary command length is
greater than BUFSIZ or 2*BUFSIZ + 20. Do not use sprintf when its
result might not fit in 'int'.
* emacsclient.c (xmalloc): Accept size_t, not unsigned int, to
avoid potential buffer overflow issues on typical 64-bit hosts.
Return void *, not long *.
(get_current_dir_name): Report a failure, instead of looping
forever, if buffer size calculation overflows. Treat malloc
failures like realloc failures, as that has better behavior and is
more consistent. Do not check whether xmalloc returns NULL, as
that's not possible.
(message): Do not arbitrarily truncate message to 2048 bytes when
sending it to stderr; use vfprintf instead.
(get_server_config, set_local_socket)
(start_daemon_and_retry_set_socket): Do not alloca
arbitrarily-large buffers; that's not safe.
(get_server_config, set_local_socket): Do not use sprintf when its
result might not fit in 'int'.
(set_local_socket): Do not assume uid fits in 'int'.
Assume support for memcmp, memcpy, memmove, memset.
This simplifies the code a bit. All current platforms have these,
as they are required for C89. If this turns into a problem we
can add the gnulib modules for these (a 1-line change to Makefile.in).
* configure.in: Don't check for memcmp, memcpy, memmove, memset.
[lib-src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* etags.c (absolute_filename): Assume memmove exists.
[src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
* regex.c (memcmp, memcpy):
Remove; we assume C89 now.
* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
(__malloc_safe_bcopy): Remove; no longer needed.
(main) [!MAIL_USE_SYSTEM_LOCK]: Prefer mkstemp to mktemp, as this
fixes some race conditions. Report mkstemp/mktemp errno rather
than a possibly-garbage errno. Reinitialize the template each
time through the loop, as earlier mkstemp/mktemp calls could have
trashed it. Pass 0600 (not 0666) to mktemp, for consistency
with mkstemp; the permissions don't matter anyway.
* lib-src/Makefile.in (.c.o): Remove (every .o file has an explicit rule).
(insrcdir): New.
(stamp-rcs2log, stamp-rcs-checkin, stamp-grep-changelog, stamp-vcdiff):
Use $insrcdir to suppress unaesthetic ignored errors.
(clean): Simplify list of things to delete.
See discussion in http://debbugs.gnu.org/8302
* configure.in (NS_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
(WINDOW_SUPPORT): Remove output variables that are no longer used.
* lib-src/makefile.w32-in (echolisp): Remove rule that is no longer needed.
(clean): No more echolisp.tmp.
* .bzrignore: Remove lib-src/echolisp.tmp.
* lisp/emacs-lisp/autoload.el (batch-update-autoloads):
Set autoload-excludes by parsing lisp/loadup.el rather than Makefiles.
* lisp/loadup.el: Update commentary.
* msdos/sed1x.inp (TOOLTIP_SUPPORT, WINDOW_SUPPORT):
* msdos/sed1v2.inp (MSDOS_SUPPORT, NS_SUPPORT, MOUSE_SUPPORT)
(TOOLTIP_SUPPORT, WINDOW_SUPPORT): No need to edit these any more.
* src/Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
(REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
(BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
(lisp): Set the order to that of loadup.el.
(shortlisp): Make it a copy of $lisp.
(SOME_MACHINE_LISP): Remove.
($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
Use just $shortlisp, not $SOME_MACHINE_LISP too.
This avoids a warning with gcc -Wstrict-overflow, and works
better for very large objects.
(inbuffer_size): Now size_t. All uses changed.
(xmalloc, xrealloc, operator_name, process_file): Use size_t for
sizes. Don't bother testing whether a size_t value can be negative.
This avoids a warning with gcc -Wstrict-overflow.
* etags.c (Prolog_functions, prolog_pr, prolog_atom): Use size_t,
not int, to store sizes.
(prolog_atom): Return 0, not -1, on error. All callers changed.
