(search_image_cache, uncache_image, image-refresh): New functions.
Check for fg and bg colors.
(lookup_image): Use search_image_cache. Cache fg and bg colors.
(pbm_load): Another check for invalid image data.
(png_load): Ignore default background field.
* image.c: Sync to trunk version.
(search_image_cache, uncache_image, image-refresh): New functions.
Check for fg and bg colors.
(lookup_image): Use search_image_cache. Cache fg and bg colors.
(pbm_load): Another check for invalid image data.
(png_load): Ignore default background field.
[USE_PTHREAD] (LOCK, UNLOCK, LOCK_ALIGNED_BLOCKS)
(UNLOCK_ALIGNED_BLOCKS): Conditionalize with it.
(malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
(malloc_atfork_handler_child, malloc_enable_thread) [USE_PTHREAD]:
New functions.
(vc-bzr-command): Remove redundant setting of process-connection-type.
(vc-bzr-admin-checkout-format-file): Add autoload.
(vc-bzr-root-dir): Remove in favor of vc-bzr-root.
(vc-bzr-root): Switch to implementation of vc-bzr-root-dir.
(vc-bzr-registered): Compare dirstate format tag with known good
value, abort parsing if match fails. Warn user in docstring.
(vc-bzr-workfile-version): Case for different Bzr branch formats.
See bzrlib/branch.py in Bzr sources.
(vc-bzr-diff): First argument FILES may be a string rather than a list.
(vc-bzr-shell-command): Remove in favor of
vc-bzr-command-discarding-stderr.
(vc-bzr-command-discarding-stderr): New function.
program, and return nil
(vc-bzr-state): Gracefully handle missing "bzr" program, and return nil.
(vc-bzr-state): Look for path names relative to the repository
root after status keyword.
(vc-bzr-file-name-relative): New function.
(vc-bzr-admin-dirname): Reinstate, as other vc-bzr-admin-... paths
depend on it.
(vc-bzr-admin-dirname, ...-checkout-format-file)
(...-branch-format-file, ...-revhistory): Paths to some Bzr internal
files that we now parse directly for speed.
(vc-bzr-root-dir): Use `vc-bzr-admin-checkout-format-file' as witness.
(vc-bzr-registered): Only parse vc-bzr-admin-dirstate file if it exists.
(vc-bzr-state): "bzr status" successful only if exitcode is 0
(vc-bzr-root): Use `vc-bzr-shell-command'. Stderr may contain
Bzr warnings, so we must discard it.
(vc-bzr-workfile-version): Speedup counting lines from
`vc-bzr-admin-revhistory' file, but fallback to spawning "bzr revno"
if that file doesn't exist.
(vc-bzr-responsible-p): Use `vc-bzr-root' instead of
`vc-bzr-root-dir' for speed.
add `vc-bzr-admin-dirname' (not ".bzr"!) to `vc-directory-exclusion-list'
(vc-bzr-shell-command): New function.
Activate it with add-hook on buffer-save-hook.
(newline, newline-and-indent, do-auto-fill): Use advice instead of
redefining the function.
(tpu-set-scroll-margins): Activate the pieces of advice.
(window_min_size_1, size_window, Fdisplay_buffer)
(Fsplit_window, adjust_window_trailing_edge): Use it to avoid
windows without mode- or header-lines when window-min-height is
too small.
(size_window): Reset nodelete_p after testing it, following an
earlier note by Kim F. Storm.
(display_buffer): Do not set split_height_threshold to twice the
value of window_min_height to avoid changing the value of a
customizable variable. Rather explicitly check whether the
height of the window that shall be splitted is at least as large
as split_height_threshold.
(Fwindow_full_width_p): New defun.
(syms_of_window): Defsubr it.
(Fdisplay_buffer): Use NILP.
(Fset_window_scroll_bars): Likewise.
