+
+ * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
+ segfault when there are lots of overlays.
+
+ * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
+ when there are lots of overlays. See
+ http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
+ for the details and a way to reproduce.

+
+ * fileio.c: Use O_APPEND to append.
+ This corresponds better to the natural interpretation of "append",
+ and avoids the need to open the output file twice, or to invoke
+ lseek when APPEND is neither nil nor a number.
+ This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
+ (Fwrite_region): Simplify. Use O_APPEND instead of opening the
+ file possibly twice, and lseeking to its end; this avoids the
+ need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
+ at the same time: the combination is never needed and apparently
+ it doesn't work with DOS_NT.
+
+ Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
+ * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
+
+ Allow floating-point file offsets.
+ Problem reported by Vitalie Spinu in
+ <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
+ * fileio.c (emacs_lseek): Remove.
+ (file_offset): New function.
+ (Finsert_file_contents, Fwrite_region): Use it.

+
+ * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
+ aborting on Fsignal (Bug#13289).
+
+2013-01-19 Eli Zaretskii <eliz@gnu.org>
+
+ * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
+ set_file_security as failure due to insufficient privileges.
+ Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
+ (fstat): Return owner and group like 'stat' and 'lstat' do.
+
+2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ Work around bug in CIFS and vboxsf file systems (Bug#13149).
+ The bug was observed on Ubuntu operating inside a virtual machine,
+ editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
+ The workaround introduces a race condition on non-buggy hosts,
+ but it's an unlikely race and anyway there's a nearly identical
+ nearby race that can't be fixed.
+ * fileio.c (valid_timestamp_file_system, timestamp_file_system):
+ New static vars.
+ (Fwrite_region): Test for file system time stamp bug.
+ (init_fileio): New function.
+ * lisp.h (init_fileio): Declare it.

+ and make it more consistent with other stat-failure diagnostics.

+
+ Fix crash when inserting data from non-regular files. See
+ http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
+ for the error description produced by valgrind.
+ * fileio.c (read_non_regular): Rename to read_contents.
+ Free Lisp_Save_Value object used to pass parameters.
+ (read_non_regular_quit): Rename to read_contents_quit.
+ (Finsert_file_contents): Redesign internal file reading loop to adjust
+ gap and end positions after each read and so help make_gap to work
+ properly. Do not signal an I/O error too early and so do not leave
+ not yet decoded characters in a buffer, which was the reason of
+ redisplay crash. Use list2 to build return value. Adjust comments.
+
+2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ Close a race when statting and reading files (Bug#13149).
+ * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
+ This avoids a race if the file is renamed between stat and open.
+ This race is not the problem originally noted in Bug#13149;
+ see <http://bugs.gnu.org/13149#73> and later messages in the thread.
