This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);
> -->
> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");

This function is an infallible alternative to nsIURI::GetSpec(). It's useful
when it's appropriate to handle a GetSpec() failure with a failure string, e.g.
for log/warning/error messages. It allows code like this:
nsAutoCString spec;
uri->GetSpec(spec);
printf("uri: %s", spec.get());
to be changed to this:
printf("uri: %s", uri->GetSpecOrDefault().get());
This introduces a slight behavioural change. Previously, if GetSpec() failed,
an empty string would be used here. Now, "[nsIURI::GetSpec failed]" will be
produced instead. In most cases this failure string will make for a clearer
log/warning/error message than the empty string.

Bug 1297961 (part 1b) - More GetSpecOrDefault() additions. r=hurley.
I will fold this into part 1 before landing.

If the mathml.disabled preference is true, treat <math> and other MathML
elements as generic XML elements.
This patch disables the rendering code of MathML however preserves the
namespace so to reduce the breakage.

assert that is not safe to run script in quite a few places :(

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

This includes, for example :hover.
Also removes the call to IsStyledByServo() in the document constructor, it's not
only unnecessary, but also we call UpdateStyleBackendType() too early.

Shift+backspace causes a forward delete on some platforms, but not on
Android. The new Google keyboard is sending us shift+backspace, and we
need to handle it normally like a backspace.
This is kind of a long story, stay with me on this.
In bug 990290, a WeakMap was added to any JS scope that loaded an XBL
binding. That WeakMap stored the JS prototypes that are injected into
a bound node's prototype chain.
When a binding is removed, we search the prototype chain for the
JS prototype that we'd added, and remove it.
The XUL prototype cache caches numerous things, including nsXBLDocumentInfo,
which we use to get at the nsXBLPrototypeBinding for a particular binding,
which is then used to generate the class object that's put into the WeakMap.
When the XUL prototype cache is flushed, that means that when a binding
is bound, its definition needs to be reloaded off of the disk. If, however,
there was a pre-existing instance of the binding already being used in a
document, now we were in a funny case.
We were in a funny case, because when attempting to remove a binding, we
would look up the nsXBLPrototypeBinding via the nsXBLDocumentInfo that's
being held within the nsXULPrototypeCache, find (or load off the disk) a
_new_ nsXBLDocumentInfo and generate a _new_ nsXBLPrototypeBinding that
did not match to the one that we'd already stored in the WeakMap. This
would mean that removal would go wrong, and things would break horribly.
This patch makes it so that we prioritize checking the nsBindingManager
for a document for the nsXBLDocumentInfo before checking the
global nsXULPrototypeCache. That way, even if the cache gets cleared,
if the binding was ever used in this document, it'll be in the
nsBindingManager, and we'll get the same nsXULProtoypeBinding that
we'd been using before, and sanity will prevail.

eKeyDownOnPlugin (mozkeydownonplugin) and eKeyUpOnPlugin (mozkeyuponplugin) should execute if the key combination is reserved by the linked <command> element.
Note that there is no eKeyPressOnPlugin. Therefore, eKeyDownOnPlugin may execute shortcut key handler which is registered as a keypress event handler.

If a plugin process posts native key events to the widget, it needs to check if the key combination is reserved by chrome because if it's reserved by chrome, the reserved shortcut key handler should be executed and the event shouldn't be handled by the focused plugin.
This patches add eKeyDownOnPlugin and eKeyUpOnPlugin. nsXBLWindowKeyHandler will listen to them and handle them as normal keydown and keypress or keyup event. Note that these events won't be fired on content in the default event group and won't be sent to the remote process.

js::Class op are often all null. And when they're not all null, they're often
duplicated among classes. By pulling them out into their own struct, and using a
(possibly null) pointer in js::Class, we can save 114 KiB per process on
64-bit, and half that on 32-bit.
