* 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?

* 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.

 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.

 src/xdisp.c (append_stretch_glyph): In a R2L glyph row, decrease the
 pixel width of the first glyph that is hscrolled from display.
 (display_line): In R2L glyph rows, don't give a negative offset to
 row->x when the first glyph begins before first_visible_x.

* macros.c (Fstart_kbd_macro): Initialize kbd_macro_ptr and
kbd_macro_end together with kbd_macro_buffer.

 src/xdisp.c (display_line): If called with iterator set up to write
 to a marginal area, delay the call to handle_line_prefix until we
 switch back to the text area.

 src/.gdbinit (xwindow): The members total_cols, total_lines,
 left_col, and top_line are C integers (and has been so for the
 last 1.5 years).

* macfont.m (macfont_update_antialias_threshold): Remove static.

* nsterm.h (EmacsApp): Add antialiasThresholdDidChange.

* nsterm.m (applicationDidFinishLaunching:): Call
antialiasThresholdDidChange, register for antialias changes.
(antialiasThresholdDidChange:): New method for EmacsApp.

 src/w32select.c (setup_windows_coding_system): Apply
 CODING_ANNOTATION_MASK to the common_flags member of struct
 coding_system.  Reported by Martin Rudalics <rudalics@gmx.at>.
 src/w16select.c (Fw16_get_clipboard_data): Apply
 CODING_ANNOTATION_MASK to the common_flags member of struct
 coding_system.

 src/xdisp.c (hscroll_window_tree): Don't try hscrolling windows whose cursor
 row has zero buffer position as their start position.  Reported by
 Martin Rudalics <rudalics@gmx.at>.

 src/xdisp.c (init_iterator): Initialize it->stop_charpos to the
 buffer position where we are to start the iteration.
 (handle_invisible_prop): Record in it->stop_charpos the position
 where the invisible text ends.

 src/xdisp.c (move_it_vertically_backward, move_it_by_lines): Prevent
 infinite looping in redisplay when display lines don't have enough
 space to display even a single character.

 src/xdisp.c (decode_mode_spec): Call file-remote-p on the current
 buffer's default-directory only if it is a string.

 lisp/bindings.el (mode-line-remote): If default-directory is not a
 string, don't call file-remote-p on it; instead state in the
 help-echo that it is nil.

 src/xdisp.c (display_line): Don't call FETCH_BYTE with argument less than 1.

 etc/PROBLEMS: Mention the problem from bug #17950.

 src/w32fns.c (Fx_file_dialog): Mention in the doc string the
 behavior on Windows 7 and later when the function is repeatedly
 invoked with the same value of DIR.
 src/xfns.c (Fx_file_dialog) [USE_MOTIF, USE_GTK]: Update the doc
 string to match the one in w32fns.c.

 src/xdisp.c (move_it_to): Adjust calculation of line_start_x to what
 x_produce_glyphs does when it generates a stretch glyph that
 represents a TAB.

 src/xdisp.c (pos_visible_p): 	Fix condition for finding CHARPOS by the
 first call to move_it_to.

 src/xdisp.c (pos_visible_p): If CHARPOS is at beginning of window,
 and there is a display property at that position, don't call
 move_it_to to move to a position before window start.

 src/xdisp.c (pos_visible_p): If CHARPOS is at BEGV, and there is a
 display property at BEGV, don't call move_it_to to move to a
 position before BEGV.

if !open_paren_in_column_0_is_defun_start.
(back_comment): If find_defun_start was pessimistic, use the
scan_sexps_forward result to improve the cache.

* xfns.c (create_frame_xic): Pass XNStatusAttributes to XCreateIC
only if xic_style calls for it.  This change allows Emacs to work
with ibus.  Also, don't leak resources if create_frame_xic fails,
and stop caching xic_style across different displays.
(supported_xim_styles): Make const.
(best_xim_style): Remove first parameter: it's always just
supported_xim_styles.  Change to look at supported_xim_styles
directly.

 src/xdisp.c (redisplay_window): If redisplay of a window ends up
 with point in a partially visible line at end of the window, make
 sure the amended position of point actually has smaller Y
 coordinate; if not, give up and scroll the display.
 src/window.c (window_scroll_pixel_based): When point ends up at the
 last fully visible line, don't let move_it_to stop at the left
 edge of the line and dupe us into thinking point is inside the
 scroll margin.

 src/dispnew.c (prepare_desired_row): Accept 2 additional arguments:
 the window whose glyph row is being prepared and a flag whether it
 is for mode/header line.  Make sure the glyph row's marginal areas
 are in sync with what the window wants.
 src/xdisp.c (display_line, display_mode_line): Call
 prepare_desired_row with additional arguments, as appropriate.
 src/dispextern.h (prepare_desired_row): Adjust prototype.
 src/window.h: Improve commentary of the marginal columns.

caused by xw_popup_dialog in daemon mode (Bug#17891).

 src/frame.c (do_switch_frame): When switching to another TTY frame,
 make sure FrameCols and FrameRows are in sync with the new frame's
 data.

* coding.c (encode_coding_utf_8): Correctly count produced_chars
also in unibyte case.

Fixes: debbugs:17846

 src/indent.c (Fvertical_motion): Move to the goal column, if any,
 with a single call to move_it_in_display_line, not in two calls.
 Doing this with two calls causes move_it_in_display_line apply the
 line-prefix handling twice instead of just once.

 src/indent.c (Fvertical_motion): Doc fix.

 doc/lispref/positions.texi (Screen Lines): Clarify how columns are counted
 by vertical-motion.

* fileio.c (Ffile_acl): Port to OS X, where acl_get_file (...,
ACL_TYPE_ACCESS) doesn't work.

 src/image.c [5 < GIFLIB_MAJOR + (1 <= GIFLIB_MINOR)]: Declare the
 prototype of DGifCloseFile as appropriate for older and newer
 versions of giflib.
 (gif_close): New function, encapsulates the differences in the
 calling sequence of DGifCloseFile before v5.1.0 and after it.

 error string where appropriate.
