* * window.h (struct window): Change window_end_valid member fromDmitry Antipov2013-01-221-0/+16
| | | | | | | | | | | | | | | Lisp_Object to a bitfield. Adjust comments. (wset_window_end_valid): Remove. * window.c (adjust_window_count): Clear window_end_valid. (Fwindow_end): Adjust user. Remove ancient #if 0 code. (Fwindow_line_height, set_window_buffer, Frecenter) (Fsplit_window_internal, Fdelete_other_windows_internal) (Fset_window_fringes, Fset_window_scroll_bars): Adjust users. * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise. * xdisp.c (check_window_end, reconsider_clip_changes) (redisplay_internal, mark_window_display_accurate_1, redisplay_window) (try_window, try_window_reusing_current_matrix, note_mouse_highlight) (find_first_unchanged_at_end_row, try_window_id): Likewise.
* * xdisp.c (mark_window_display_accurate): Simplify the loopDmitry Antipov2013-01-221-0/+9
| | | | | | | | assuming that the only one of vchild, hchild or buffer window slots is non-nil. Call mark_window_display_accurate_1 for the leaf windows only. (mark_window_display_accurate_1): Always assume leaf window. Adjust comment.
* * emacs.c (Qkill_emacs_hook): Now static.Paul Eggert2013-01-211-0/+2

* * fileio.c (Finsert_file_contents): Simplify.Paul Eggert2013-01-211-0/+5
| | | | Remove unnecessary assignments and tests.
* Another minor fix in acl_set_file on Windows.Eli Zaretskii2013-01-211-0/+6
| | | | | | 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 Antipov2013-01-211-0/+7
| | | | | | 2013-01-18 in favor of the simpler and generally better fix. Save stack space by removing 'buffer' and reusing 'read_buf' where appropriate.
* * lisp.h (eabs): Define unconditionally.Paul Eggert2013-01-191-0/+6
| | | | | | | The old "#if !defined (eabs)" was an unnecessary revenant of back when this macro was called "abs". Document 'eabs' better. Fixes: debbugs:13419

| * * src/fns.c (Frandom): Doc fix.Glenn Morris2013-01-161-0/+4

* | Fix crashes with lots of overlays.Eli Zaretskii2013-01-191-0/+10
| | | | | | | | | | | | | | | | | | 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 Eggert2013-01-191-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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.Paul Eggert2013-01-191-0/+3
| | | | | | | | | | | | * fileio.c (Fwrite_region): Use O_BINARY in checking code, too. Fixes: debbugs:13149
* | Allow floating-point file offsets.Paul Eggert2013-01-191-0/+9
| | | | | | | | | | | | | | | | | | | | 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.
* | * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid aborting on ↵Chong Yidong2013-01-191-0/+5
| | | | | | | | | | | | Fsignal. Fixes: debbugs:13289
* | Make 'fstat' on MS-Windows behave more like 'stat' and 'lstat'.Eli Zaretskii2013-01-191-0/+1
| | | | | | | | src/w32.c (fstat): Return owner and group like 'stat' and 'lstat' do.
* | Minor fix in acl_set_file.Eli Zaretskii2013-01-191-0/+6
| | | | | | | | | | | | 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 Eggert2013-01-181-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | * fileio.c (Finsert_file_contents): Simplify new diagnosticPaul Eggert2013-01-181-0/+5
| | | | | | | | and make it more consistent with other stat-failure diagnostics.
* | Fix crash when inserting data from non-regular files. SeeDmitry Antipov2013-01-181-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Eggert2013-01-171-0/+8
| | | | | | | | | | | | | | * 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.
* | * lisp.h (toplevel): Add comment about using Lisp_Save_ValueDmitry Antipov2013-01-171-0/+16

Likewise for format_save_value and make_save_value.
