We were keeping nsDocShell::mHistoryId and nsDocShell::mOSHE as keys. They
weren't quite good because:
1. While loading an iframe, they were being registered twice with the same
ids(for about:blank and the real URL) sometimes.
2. It wasn't possible to access to the parent mHistoryId and mOSHE from a child
processes if the parent is in a different process. That may not be the case for
now, but it will be after fission.
So we had to find other IDs to:
1. Determine the Tab of the frames.
2. Determine the URLs of the frames.
For the first use case, we were using nsDocShell::mHistoryId for that purpose
but that was wrong. The closest thing that we can get to a tab ID is
BrowsingContext ID because they don't change after a navigation. But iframes
have different BrowsingContext's, so we still need to create a tree to
construct a tab content. That can be either in the front-end or capture time.
For the second use case, we were using a key pair of mHistoryId and mOSHE. We
now chose to keep inner window IDs for that purpose. Inner window IDs are
unique for each navigation loads because inner window correspond to each JS
window global objects. That's why we can use that without any problem. But one
problem is that we cannot handle `history.pushState` and `history.replaceState`
changes with that change since window global objects won't change during those.
But that was the best thing we can do after fission. So this will be a small
sacrifice for us to keep that functionality working after fission.
In that patch we also remove the registration/unregistration calls. We are
going to add those calls in the next patch.

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
patch will enable performing async process launching through the
NewOrUsedBrowserProcess mechanism.
I know of at least a few timing issues which exist with the new logic,
especially around the state of the BrowsingContext during the process
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
BrowsingContext substantially. I do, however, think that the new logic is more

BrowsingContext.findWithName is required to do access checks based on the
requestor, which can only be done in the process which owns it. This change
also alters the behavior of the existing CanAccess origin checks, which
typically treat any item as same-origin, but only when the docshells are
actually same process.
Removing the exemption fixes the behavior discrepancy between Fission and
non-Fission runs, but also requires that the test be updated to expect proper

In the Quantum Bar it's usually the urlbar code that decides whether a search
string should be visited or searched. if dns_first_for_single_words is set,
we can't make a final decision, because that depends on a dns lookup. For now
we don't want to duplicate the docshell code, also because we must keep the
old behavior functioning for cases where the urlbar value is set without input.
Similarly, when the docshell decides to search for a single word host, and a
dns lookup resolves it, it also shows a prompt asking the user if he meant to
visit it instead of searching. Because the urlbar skips the docshell decision
making, we must manually call the fixup prompt code from the urlbar.

The (non-normative) window.open spec does not specify what should happen when
window.open is called on a window with a null/discarded browsing context, but
in general the lookup and creation rules do not make sense when the window has
no BC. It does, however, specify that we should return null when a target BC
cannot be found or created, and gives us broad discretion over when we decide
to ignore a load request and return null. Since we can't trigger a
cross-process load from a discarded BC, simply aborting in that case seems
like the logical solution.
For Location objects, the spec is more specific, and requires that we ignore
load attempts on Location objects whose documents are null, which in our
implementation corresponds to a discarded BrowsingContext.
LocationBase::SetURI already enforces this, but a second check in
BrowsingContext::LoadURI is probably a good idea as well.

This patch cleans up remote outer window proxies when we navigate back
into the process.
It adds a flag to mDanglingRemoteOuterProxies that is set in between
BrowsingContext::SetDocShell(), where we can tell that the browsing
context is going from being remote to being local, to
nsGlobalWindowOuter::SetNewDocument(), where the local outer window
proxy is actually created. Once the outer window is created, the
remote window proxies can be cleaned up in
CleanUpDanglingRemoteOuterWindowProxies().
The clean up is done by a process that is similar to object
transplanting, except that instead of looking in the cross-compartment
wrapper table for each compartment to find objects to be turned into
CCWs to the new object, it looks in the remote proxy map for each
compartment. SpiderMonkey doesn't know about the proxy maps, so this
has to be done by a new callback object CompartmentTransplantCallback.
Now that this cleanup is being done, it shouldn't be possible to wrap
a remote outer window proxy when the browsing context is local, so
MaybeWrapWindowProxy() can be simplified. I had to drop the assert
here that the browsing context has a window proxy because during clean
up we call wrap on a local outer window proxy before the BC gets the
window proxy set on it. I had the assert because my original plan was
to implicitly fix remote proxies during wrapping, but that is no
longer necessary.

For some reason, these timeouts aren't reported as timeouts on automation. The
tests just fail after sitting for 5 minutes doing nothing. Locally, though,
they are reported as timeouts.
Either way, they make the test group run 15 minutes longer than necessary.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

When a BrowsingContext changes from being local to remote, we have to
change all window proxies from being local to remote, using
transplanting. The actual window proxy becomes a remote window
proxy. Cross compartment wrappers (CCWs) to the window proxy also
become remote window proxies in their respective compartments, rather
than CCWs to a remote proxy in the old compartment of the window
proxy, because the window is no longer actually in that
compartment. This also avoids having to figure out what Xray behavior
for remote window proxies should be.
This patch uses the transplanting support I added to
GetRemoteOuterWindowProxy() in the previous patch to ensure that the
remote proxy map holds the correct value after transplanting finishes.
It drops the requirement that both arguments to JS_TransplantObject
have the same class, because we need to transplant a window proxy with
a remote window proxy. It also deals with this by not adding origobj
to the wrapper map unless it is a CCW, to handle transplanting to a
remote proxy.
The core design here, with the remote window proxies in every
compartment, is taken from a patch by peterv.

When we call GetRemoteOuterWindowProxy in the middle of a transplant,
the remote proxy that the function returns will be almost immediately
swapped with some other object. Rather than trying to fix up the
remote proxy map when that happens, this patch adds a new argument
that is a pointer to the object, if any, that the remote proxy is
going to be swapped to. This will be used in the remote proxy map.
Having a value in the remote proxy map that is not a remote proxy
could cause issues if somebody ends up calling
GetRemoteOuterWindowProxy() a second time before the transplant has
finished. To avoid that, my patch asserts that we are returning an
object with the appropriate class.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.

In the bug which introduced mIsDiscarded, the code was changed to not set
mClosed during Detach, and only set mIsDiscarded. This was a mistake because a
bunch of places are only reading mClosed. Specifically when creating a
BrowsingContext for an iframe, we check GetClosed() to see whether to skip
creating it. Not doing this check can lead to assertions like the one in this
bug.
This patch changes the behaviour to continue setting `mClosed`, and also updates
the relevant `GetClosed()` checks to correctly check `IsDiscarded()`
