On startup we record the size and modified time of the profile lists. If
changed we refuse to flush any new changes to disk. Also adds a getter to check
if they've changed so the UI can do something sensible.
All attempts to flush are now checked for success. In some cases in early
startup the failure mode isn't great, we just quit startup. The assumption
though is that it's extremely unlikely that the files will have changed on disk
in the time between when they are read and when profile selection occurs, likely
less than a second later.
The profile reset flow is changed to only delete the old profile and flush once
all the migration has completed, so if something fails the user gets back to
their old profile.
In testing I ended up having to fix bug 1522584 so background file deletions on
a background thread are safer.
I haven't implemented any UI tests right now since making modifications to the
profiles means modifying the actual user's profiles which I'm not keen to do.
See bug 1539868.

happening above it. A 50% increase to 384 MiB should be just about right in

NS_InitXPCOM() is currently not called in Gecko. It has been a one-line wrapper around NS_InitXPCOM2() since the year 2000 (bug 46320), presumably to maintain ABI compatibility for third-party users of XPCOM. We no longer need to worry about XPCOM ABI compatibility.

Originally we stored the new information about installation defaults in
installs.ini since older versions of Firefox would throw away any new data in
profiles.ini any time they made changes to the profiles. That does however mean
we have to load two files on startup.
This changes things so that we save all the data in profiles.ini as well as a

will throw away the install data and version tag from profiles.ini but leave
installs.ini alone. On startup if the version tag is gone from profiles.ini then
we reload the install data from installs.ini and put it back into profiles.ini.
At some point in the future where we don't care about supporting older versions
of Firefox we can just drop installs.ini entirely.
A lot of the changes here involve moving to loading profiles.ini into an
in-memory ini, keeping it up to date and flushing it to disk. This means that we
no longer throw away any information in the ini file that this version does not
understand allowing the possibility of adding new data to this file in the

This is a follow-up to the previous part, which actually changes one of
these callers to use Array<nsIIDRef> instead of [array] nsIIDPtr.
From doing this patch, it seems like we should consider changing
the type `nsIIDRef` to instead simply be `nsIID`, and treat it more like
the `AString` types from the POV of XPIDL. `nsIIDPtr` would then
continue to exist for backwards compatibility, but we can probably

Currently the [ref] and [ptr] types share the same underlying
implementation. This is unfortunate, and can cause correctness problems
with outparam refs (as an example).
By using the same tools used to allow other larger objects (such as
jsid, nsTArray, and nsString) to be stored directly in the nsXPTCVariant
object, this patch directly stores the nsID in the nsXPTCVariant object
when calling from JS into C++.
Using this new strategy avoids an nsID* allocation every time we pass
one over XPConnect, and should also allow us to simplify callers.
In addition, some special casing is added to xpidl to make it possible
to use the nsid reference type objects directly inside of Array<T>,
which will allow us to remove `[array] nsIIDPtr` callers.

While the behavior of ECMAScript Promises and their associated job queue is
covered by the ECMAScript standard, the HTML specification amends that with
additional behavior the web platform requires. To support this, SpiderMonkey
provides hooks the embedding can set to replace SpiderMonkey's queue with its
own implementation.
At present, these hooks are C-style function-pointer-and-void-pointer pairs,
which are awkward to handle and mistake-prone, as passing a function the wrong
void* is not a type error. Later patches in this series must add new hooks,
making a bad situation worse.
A C++ abstract base class is a well-typed alternative. This introduces a new
`JS::JobQueue` abstract class, and adapts SpiderMonkey's internal job queue and
Gecko's customization to use it. `GetIncumbentGlobalCallback` and
`EnqueuePromiseJobCallback` become virtual methods.
Within SpiderMonkey, the patch gathers the various fields of JSContext that
implement the internal queue into their own type, js::InternalJobQueue. Various
jsfriendapi functions become veneers for calls to methods specific to the
derived class. The InternalJobQueue type itself remains private to SpiderMonkey,
as it uses types like TraceableFifo, derived from Fifo, that are not part of
SpiderMonkey's public API.
Within Gecko, CycleCollectedJSContext acquires JS::JobQueue as a private base
class, and a few static methods are cleaned up nicely.
There are a few other hooks defined in js/public/Promise.h that might make sense
to turn into virtual methods on JobQueue. For example,
DispatchToEventLoopCallback, used for resolving promises of results from
off-main-thread tasks, is probably necessarily connected to the JobQueue
implementation in use, so it might not be sensible to set one without the other.
But it was left unchanged to reduce this patch's size.

The basic idea for the changes around UnwrapObjectInternal and its callers
(UnwrapObject, UNWRAP_OBJECT, etc) is to add a parameter to the guts of the
object-unwrapping code in bindings which can be either a JSContext* or nullptr
(statically typed). Then we test which type it is and do either a
CheckedUnwrapDynamic or CheckedUnwrapStatic. Since the type is known at
compile time, there is no actual runtime check; the compiler just emits a call
to the right thing directly (verified by examining the assembly output on
Linux).
The rest of the changes are mostly propagating through that template parameter,
adding static asserts to make sure people don't accidentally pass nullptr while
trying to unwrap to a type that might be a WindowProxy or Location, etc.
There are also some changes to places that were calling CheckedUnwrap directly
to use either the static or dynamic version, as needed.

Old Confluence does not aware of conflated model keypress event (see UI Events
spec, https://w3c.github.io/uievents/#determine-keypress-keyCode).
Additionally, Confluence can be hosted with any domains. Therefore, we cannot
use blacklist to disable the conflated model keypress event only on it.
This patch checks whether current or parent document is Confluence with JS
module, called KeyPressEventModelCheckerChild. For kicking this module,
nsHTMLDocument dispatches an custom event, CheckKeyPressEventModel, when it
becomes editable only first time. Finally, if it's a Confluence instance, the
module let PresShell know that we need to use split model keypress event in it.

The total size of an IPC inputStream message must be less than 1mb. When we
compose the message for the multiplex stream, each sub stream collaborates with
its own size, deciding if it's better to be a pipe stream (IPCRemoteStream) or
a full serialized one.

It relies on AC_TRY_RUN, which doesn't work on cross-compiles. What this
means is that the feature has been disabled on mac builds on automation
ever since we switched to cross-compiles. It's still enabled on local
mac builds because the test runs there, and returns "yes". It also means
it's disabled on Android, where it probably works (at least debug tests
on try don't complain).
It also doesn't currently run on Windows because it's in a skipped
section on Windows, but if moved out of that section, the test returns
"no".
So, we remove any configure test for the feature, in favor of
preprocessor checks in nsTraceRefcnt.cpp.

We already take steps in `IndexOf` to avoid bounds checks--by using
direct pointer accesses--and we should do the same thing for binary
searches as well.
ProcessTypeRequiresWinEventHook was added when attempting to turn on win32k
lockdown for GMP processes. Having a less specific, but globally accessible,
function will make it more useful while applying win32k lockdown to other
process types.
Before this set of patches, the decision of exposing the stream as a pipe was
centralized in IPCStreamUtils, based on the total expectation size of the IPC
message. This triggers issues when multiplex inputStreams contain something
that cannot be sent as a pipe (IPCBlobInputStream, for instance), or something
that it's better to do not set as a pipe (nsFileInputStream), together with
memory streams (nsStringInputStream), which could make the IPC message greater
then what accepted (1mb).
These patches move the "pipe vs non-pipe" choice into the single inputStream
implementation.
In order to test the test harness's handling of a process failing to
produce a leak log, add a special function that disables the bloat log
output.

This changes the policy to use the pref and permissions rather than a boolean flag. Using permissions gets us proper settings on startup without introducing any new overhead. Going this way flips our tests around so rather than testing an override to turn off private browsing support, we test overrides to enable private browsing support.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.
