src/w32fns.c (w32_createwindow): Accept an additional argument, an
array of 2 values specifying the coordinates of the frame's
top-left corner. Use these values instead of calling x_get_arg,
which can cons Lisp objects, and therefore cannot be called except
from the main thread. Remove redundant tests for the default
values.
(my_create_window): Move the calculation of the coordinates of the
frame's top-left edge here. Pass them to the input thread via the
second parameter of the WM_EMACS_CREATEWINDOW message. See
http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00892.html
for the details.
src/xdisp.c (cursor_row_fully_visible_p): Update commentary.
(redisplay_window): Treat the frame's frozen_window_starts flag
the same way as the optional_new_start flag for the window: only
obey it if the glyph row showing point will be fully visible.
Likewise when the window start is in a continuation line. If,
after trying everything under the 'force_start' label, point is
still not fully visible, give up and scroll the window. Add
debugging traces.
src/window.c (Frecenter): Set the window's redisplay flag.
src/w32term.c (w32_read_socket): Don't use frame dimensions for
resizing if GetClientRect returned an empty (0, 0, 0, 0)
rectangle. Check the return value of GetClientRect, and don't use
the results if it didn't succeed.
src/dispnew.c (change_frame_size_1): Recompute the frame dimensions
in columns and lines after correcting the pixel dimensions in
check_frame_size.
(adjust_decode_mode_spec_buffer): Add assertion to avoid passing
negative values to xrealloc.
src/xterm.c (x_draw_hollow_cursor, x_draw_bar_cursor):
src/w32term.c (x_draw_hollow_cursor, x_draw_bar_cursor): In R2L
lines, draw the hollow-box and hbar cursors on the right side of
cursor-glyph. Thanks to Martin Rudalics <rudalics@gmx.at> for
testing on X.
src/xterm.c (x_draw_stretch_glyph_string):
src/w32term.c (x_draw_stretch_glyph_string): Fix a thinko that
caused the block cursor to disappear on a TAB in R2L lines in
every window except the leftmost one. Reported by Martin Rudalics
<rudalics@gmx.at>.
* lisp.h (record_in_backtrace): Adjust prototype.
* eval.c (record_in_backtrace): Return current specpdl level.
(set_backtrace_args, set_backtrace_nargs): Merge. Adjust all users.
(eval_sub, Ffuncall): Record call arguments in matched specpdl
entry and use that entry in call to backtrace_debug_on_exit.
(apply_lambda): Likewise. Get current specpdl level as 3rd arg.
(do_debug_on_call): Get current specpdl level as 2nd arg.
src/xdisp.c (init_iterator): Don't use it->bidi_p before it is
assigned the correct value.
(extend_face_to_end_of_line): Account for truncation and
continuation glyphs in R2L rows when one of the fringes is not
displayed.
(display_line): Don't assign negative X offset to a row if we are
going to produce a truncation glyph for it. When handling
truncated R2L rows, consider the width of the left fringe instead
of the right one.
(produce_special_glyphs): Fix bogus assignments.
src/w32.c (fcntl): Support O_NONBLOCK fcntl on the write side of
pipes.
(sys_write): When a write to a non-blocking pipe returns ENOSPC,
set errno to EAGAIN instead, to allow the caller to retry the
write after some waiting. Fixes deadlocks when Emacs exchanges a
lot of data through the pipe.
src/sound.c (Fplay_sound_internal): Encode the sound file name in
the ANSI codepage. Expand it against data-directory, as per docs,
not against the current directory. No need to make a local copy
of the file name; pass the encoded file name directly to
do_play_sound. (Bug#18463)
src/w32.c (ansi_encode_filename): If w32_get_short_filename returns
NULL, and the file name is not encodable in ANSI codepage, return
the string with "?" replacement characters, which will fail the
caller. This avoids returning a random value in that case.
src/xdisp.c (pos_visible_p): Properly save and restore the iterator
state around the call to line_bottom, since it can move the
iterator to another screen line. This fixes off-by-one errors in
the reported row in some rare cases.
src/data.c (set_internal): Use assq_no_quit, not Fassq, to find an
existing binding of a variable, to avoid silently aborting
commands that use specbind.
lisp/subr.el (posn-col-row): Revert the change from commit
2010-11-13T21:07:58Z!eliz@gnu.org, which
was inadvertently merged from emacs-23 release branch in
2010-11-18T03:54:14Z!monnier@iro.umontreal.ca, and
introduced an off-by-one error in the reported row when there is a
header line.
src/dispnew.c (buffer_posn_from_coords): Fix an off-by-one error in
the reported row in the case of a window with a header line, by
improving on the fix committed in 2011-10-08T10:58:50Z!eliz@gnu.org
eliz@gnu.org-20111008105850-ht4tvsayohvr1kjc.
src/xdisp.c (display_and_set_cursor): Call erase_phys_cursor also
when HPOS is negative, for the benefit of R2L glyph rows whose
newline overflows into the fringe.
msdos/sedlibmk.inp (gl_LIBOBJS): Add execinfo.o. Reported by Juan
Manuel Guerrero <juan.guerrero@gmx.de>.
src/conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Don't define.
src/xdisp.c (display_line): Don't assume that the call to
reseat_at_next_visible_line_start ends up at a character
immediately following the newline on the previous line. Avoids
setting the ends_at_zv_p flag on screen lines that are not at or
beyond ZV, which causes infloop in redisplay. For the details, see
http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00368.html.
It causes a more serious problem than the one it solves.
This closes bug#18141, and reopens bug#13522.
* lisp/files.el (basic-save-buffer-2): Revert 2013-01-31 change.
* src/fileio.c: Revert 2013-01-31 change.
(choose_write_coding_system): No longer callable from Lisp.
Move last piece back here from Fwrite_region.
(Fwrite_region, syms_of_fileio): Update for above changes.
* test/automated/data/files-bug18141.el.gz: New file.
* test/automated/files.el (files-test-bug-18141-file):
New variable and test.
* xfns.c (Fx_create_frame): Move call to change_frame_size to
a section where Lisp evaluation is disabled. This way a pointer
to uninitialized frame is not accessible from Lisp, which becomes
critical if following call to x_figure_window_size throws an error.
* src/dired.c (directory_files_internal): Use a volatile variable
to prevent the compiler from optimizing away all copies of a local.
I wonder how many other GC-related bugs like this lurk elsewhere?
Fixes: debbugs:16986
* src/xterm.h (struct x_display_info): New member 'connection'.
* src/xterm.c (x_term_init, x_delete_terminal): Set and use it,
so that x_delete_terminal has a file descriptor to pass to
delete_keyboard_wait_descriptor.
Fixes: debbugs:17691
See http://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00476.html
for the details.
src/xdisp.c (extend_face_to_end_of_line): If the last glyph of an
R2L row is visible only partially, give the row a negative x
offset.
(display_line): Fix the calculation of the glyph whose pixel width
is used to decide whether the last produced glyph fits on the
line. When the last glyph fits only partially, give the row a
negative x offset.
