CLOSED TREE
This restores external view source after changes in bug 1025146. It does
function in e10s, however the page descriptor is not used, so viewing a POST
result will GET the page instead. This is the same as it was before bug
1025146.
Follow ups will add usage tracking and improve e10s behavior if there is enough
usage.
We were passing around content window CPOWs before to indicate
which content to send to the printer. This was, naturally, causing
unsafe CPOW usage warnings - especially when attempting to get at
the content window of an iframe with the context menu printing
command.
This patch changes the printing mechanism to use outer window IDs
instead of CPOWs.
We weren't making the print preview browser remote for the view source
window if the view source browser was remote, causing us to fail to
show the preview.
<xul:browser>'s do not get messageManager's constructed for them unless they
have their type attribute set to "content", "content-targetable", or
"content-primary". This patch updates the view source print preview browser
with that type attribute, and also updates the PrintUtils documentation to
mention this requirement.
The -*- file variable lines -*- establish per-file settings that Emacs will
pick up. This patch makes the following changes to those lines (and touches
nothing else):
- Never set the buffer's mode.
Years ago, Emacs did not have a good JavaScript mode, so it made sense
to use Java or C++ mode in .js files. However, Emacs has had js-mode for
years now; it's perfectly serviceable, and is available and enabled by
default in all major Emacs packagings.
Selecting a mode in the -*- file variable line -*- is almost always the
wrong thing to do anyway. It overrides Emacs's default choice, which is
(now) reasonable; and even worse, it overrides settings the user might
have made in their '.emacs' file for that file extension. It's only
useful when there's something specific about that particular file that
makes a particular mode appropriate.
- Correctly propagate settings that establish the correct indentation
level for this file: c-basic-offset and js2-basic-offset should be
js-indent-level. Whatever value they're given should be preserved;
different parts of our tree use different indentation styles.
- We don't use tabs in Mozilla JS code. Always set indent-tabs-mode: nil.
Remove tab-width: settings, at least in files that don't contain tab
characters.
- Remove js2-mode settings that belong in the user's .emacs file, like
js2-skip-preprocessor-directives.
Many moz.build files define things that could be defined in parent
moz.build files. Keeping the number of moz.build files low helps with
build times due to less I/O and fewer directories traversed.
This patch eliminates a lot of moz.build files by moving their content
into parent moz.build files.
