There are all sorts of lifecycle issues which arise from making DocShell
responsible for discarding BrowsingContexts. In this particular bug, we tend
to run into them in cases where we create a BrowsingContext for a FrameLoader,
and then never create a DocShell for it, leading to it never being destroyed.
But there are myriad other issues as well.
This patch moves the responsibility for BrowsingContext lifecycle management
to the FrameLoader/FrameLoaderOwner, rather than the DocShell, which makes
things more consistent, and more closely aligns with spec-defined behavior.

We go to some lengths to defer FrameLoader initialization to the end of
document updates. However, it is still possible for initialization to happen
earlier as a side-effect of other operations (such as
`nsFrameLoader::GetBrowsingContext()`) if they're called before initialization
has already happened. Since this is such an easy mistake to make, we should
assert that it doesn't happen so that we find out about it sooner rather than
later.

This flips the direction in which the BrowserBridge actor is generally created
such that it is generally created in the parent and sent down to a child
process.
This is done by making the decision about what kind of switch to perform in the
parent, and sending messages down to child processes async to orchestrate these
process changes.
Process launching is changed to use an async `MozPromise`-returning API in this
patch, though the actual process launching still occurs synchronously. A future

NewOrUsedBrowserProcess mechanism.
I know of at least a few timing issues which exist with the new logic,

transition. I decided to not try to fix all of these issues in this patch, as
many are complex and will require changing how we manage the lifecycle of

This patch changes a few things about how nsFrameLoader is created, specifically
around the ChangeRemoteness API.
1. The private 'nsFrameLoader::nsFrameLoader' constructor has been simplified to
only have one overload, shared by the different `::Create` static methods.
2. The creation static method used by `ChangeRemoteness` has changed name to
`::Recreate`, as the signature is becoming more like the old method.
3. The `mNetworkCreated` bit is preserved when doing a `ChangeRemoteness`, as a
remoteness change shouldn't be affecting that property.
4. Unused fields are removed from the ChangeRemoteness API.
5. The `remoteType` attribute is now mandatory in the ChangeRemoteness API,
which simplifies the logic and makes it harder to accidentally misuse.

This is an attempt to reduce the negative impact of bug 1553644 by replacing a
remote browser which fails to create an `mBrowserParent` actor with a tab
crashed display rather than a failed `nsFrameLoader`. This is done by firing the

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Make the WindowProxyHolder hold a strong reference to a BrowsingContext, as in the future
we might not have a nsPIDOMWindowOuter (if the document is loaded in a different process).

Every JS plugin is assigned a unique ID. When an instance of a JS plugin is created the
frame loader that we use to load the plugin's handler URI will create a special
TabContext. This TabContext causes the ContentParent to use the process for this specific

This causes the iframes for all the instances of a specific JS plugin to be grouped in the

With GroupedSHistory, history navigations may now require the browser to
change which frameloader is stored internally from within Core. This
patch adds a mechanism to allow for chrome code to respond to these
changes and both delay the change, or respond once the change is
performed.
Delaying the change is accomplished through the BrowserWillChangeProcess
event, which is fired when it is determined that a process change will
happen for the given browser, but the change has not occured yet. During
this time the nsIFrameLoader::AddProcessChangeBlockingPromise method may
be called on the target browser's frameloader. Any promises passed to
this method will be waited on, and the process change will not occur
until they have all been fulfiled.
Once that has occured, the process change occurs, and the
BrowserChangedProcess event is fired.
This is useful for chrome code which needs to flush state from the
original process before the change, and then which needs to connect
state in the new process with state in the chrome process.

This patch removes support for mozapp iframes, leaving support for
mozbrowser iframes intact. Some of the code has been rewritten in order
to phrase things in terms of mozbrowser only, as opposed to mozbrowser
or app. In some places, code that was only useful with apps has been
completely removed, so that the APIs consumed can also be removed. In
some places where the notion of appId was bleeding out of this API, now
we use NO_APP_ID. Other notions of appId which were restricted to this
API have been removed.
