| * Another minor fix in acl_set_file on Windows.Eli Zaretskii2013-01-212-37/+49
| | | | | | | | | | | | src/w32.c (acl_set_file): Don't test for errors unless set_file_security returns FALSE. Avoids spurious errors when saving files.
| * * fileio.c (Finsert_file_contents): Revert code introduced atDmitry Antipov2013-01-212-73/+110
| | | | | | | | | | | | 2013-01-18 in favor of the simpler and generally better fix. Save stack space by removing 'buffer' and reusing 'read_buf' where appropriate.

| * | Fix crashes with lots of overlays.Eli Zaretskii2013-01-193-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | src/editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid segfault when there are lots of overlays. src/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.Paul Eggert2013-01-192-23/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | * fileio.c (Fwrite_region): Use O_BINARY in checking code, too. Fixes: debbugs:13149

| * | Allow floating-point file offsets.Paul Eggert2013-01-192-32/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem reported by Vitalie Spinu in <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>. * doc/lispref/files.texi (Reading from Files, Writing to Files): Say that file offsets can be numbers, not just integers. * src/fileio.c (emacs_lseek): Remove. (file_offset): New function. (Finsert_file_contents, Fwrite_region): Use it.

| | | | | | | | | | | | src/w32.c (fstat): Return owner and group like 'stat' and 'lstat' do.
| * | Minor fix in acl_set_file.Eli Zaretskii2013-01-192-1/+8
| | | | | | | | | | | | | | | | | | src/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>.
| * | Work around bug in CIFS and vboxsf file systems.Paul Eggert2013-01-184-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * emacs.c (main): Call it. Fixes: debbugs:13149

| * | Fix crash when inserting data from non-regular files. SeeDmitry Antipov2013-01-182-102/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | Close a race when statting and reading files.Paul Eggert2013-01-172-31/+21
| | | | | | | | | | | | | | | | | | | | | * 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.
