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.

This commit hooks up nsFrameLoader in the child process to use the

In the future, we should unify nsFrameLoader to operate on a common
interface between the parent process top-level browser, and child
process subframe case. This commit just adds a new member that can
be used instead of mRemoteBrowser, when appropriate. IsRemoteFrame()
will return true for both cases.

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

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.
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.

The VisualViewport events are all nice and shiny, but unfortunately not quite
what is needed for the session store.
Firstly, the spec wants the "scroll" event to be fired only when the *relative*
offset between visual and layout viewport changes. The session store however
records the absolute offset and as such is interested in when *that* changes.
Secondly, again as per the spec the events don't bubble, and with the default
DOMEventTargetHelper implementation they don't escape the VisualViewport during
capturing, either. This means that any event listener must be added directly on
the VisualViewport itself in order to capture any events.
This might have been intended because the events use the same names as the
normal "scroll"/"resize" events, and as such you cannot specify separate event
listeners for VisualViewport and non-VisualViewport "scroll" events if both
events end up being dispatched to the same element (you can only try to filter
after the fact by looking at the originalTarget of the event).
At the same time, the VisualViewport is attached to the inner Window, and so
each time you navigate, you also get a different VisualViewport object.
All of this might be totally fine from the perspective of a page script, because
in that case you won't care anyway about what happens when the current page goes
away.
From the session store perspective on the other hand (especially Fennec's non-
e10s session store design), this is rather unfortunate because we don't want to
have to keep registering event listeners
a) manually for each subframe
b) each time the page navigates
The event target chain problem could be solved by letting the scroll events
escape the VisualViewport during the capturing phase (which the spec doesn't say
anything about), but this would mean that any scroll listener attached to a
window/browser/... that uses capturing will now catch both layout and visual
viewport scroll events.
In some cases this might even be beneficial, but in others (e.g. bug 1498812
comment 21) I'd like to specifically decide which kind of scroll event to
capture. Having to look at event.originalTarget to distinguish the two kinds
might be defensible in test code, but in case this distinction would be needed
in production code as well, given the existence of a C++-based filtering helper
in nsSessionStoreUtils for another use case where (scroll) events need to be
filtered, JS-based scroll event filtering might be a bad idea.
Additionally, in any case this wouldn't solve the fundamental conflict between
the spec and the session store about *when* the "scroll" event should be fired
in the first place.
Hence I'd like to introduce a separate set of events with distinct event names,
which will be dispatched according to the requirements of our internal users
(i.e. currently the session store). To avoid potential web compatibility issues
down the road, for now these events will be dispatched only to event listeners
registered in the system group (allowing *all* Chrome event listeners cannot be
done because checking the Chrome status of each event target might be too
expensive for frequently dispatched events).

Clang format does not always reflow comments correctly to get them
within 80 columns.
The major categories of failures I have noticed in xpcom/ are:
- Comments that are lists. I fixed these by manually getting them so
they'll be within 80 columns after clang-format runs.
- Comments intermixed with lists of things like enums, initializers,
or even fields in a class. It doesn't seem to associate the comment
with the item in the list correctly. The worst cases of these happen
when it changes initializer lists from having commas at the start of
each item to having them at the end. In the initializer comma cases,
I fixed them by making the commas at the end, so clang-format won't
mix things up. For other cases, I often moved the comment for an
item onto its own line, because it was not possible to have both the
comment and the item on the same line and stay within 80 columns.
- One odd case is nsEnumeratorUtils.cpp, where the end of line comment
after a NS_DECL macro confused clang-format and made it stop
realizing that the NS_DECL thing was a complete statement. I also
added a blank line to that file before a declaration because I think
that is better.

The core loop of Iterator::Next() requires multiple branches, one to
check for entry liveness and one to check for wraparound. We can
rewrite this to use masking instead, as well as iterating only over the
hashes, and reconstructing the entry pointer when we know we've reached
a live entry. This change cuts the time taken on the collections
benchmark by the iteration portion in half.
As discussed in the previous commit message, PLDHashTable's storage
wastes space for common entry types. This commit reorganizes the
storage to store all the hashes packed together, followed by all the
entries, which eliminates said waste.
PLDHashTable requires that all items stored therein inherit from
PLDHashEntryHdr:
struct PLDHashEntryHdr {
// PLDHashNumber is a uint32_t.
PLDHashNumber mKeyHash; // Cached hash key for object.
};
class MyType : public PLDHashEntryHdr {
// Data members, etc.
};
PLDHashEntryHdr::mKeyHash is used to cache the computed hash value of
the entry, so we aren't rehashing entries on every lookup/add/etc.
Because of structure layout requirements on 64-bit platforms, the data
members of MyType will typically start at offset 8:
MyType, offset 0: mKeyHash
MyType, offset 4: padding required by alignment
MyType, offset 8: first data member of MyType
MyType, offset N: ...
The padding at offset 4 is dead, unused space.
We'd like to change this state of affairs by having PLDHashTable manage
the cached hash key itself, which would eliminate the dead space in the
object and would enable packing the table storage more tightly. But
PLDHashTable pervasively assumes that its internal storage is an array
of PLDHashEntryHdrs (with an associated object size to account for
subclassing).
As a first step to laying out the hash table storage differently, we
have to make the internals of PLDHashTable not access PLDHashEntryHdr
items directly, but layer an abstraction on top. We call this
abstraction "slots": a slot represents storage for the cached hash key
and the associated entry, and can produce a PLDHashEntryHdr* on demand.
The only place where this is used where the const-ness matters is in
AddressEntry, and that use const_cast's away the const-ness. So let's
just ditch the method that attempts to return const pointers.
This change is satisfying insofar as it removes a load from every
iteration step over the hashtable, but it doesn't seem to affect
our collection benchmarks in any way. The change does not make
iterators any larger, as there is padding at the end of the iterator
structure on both 32- and 64-bit platforms.
This refactors the observer service code to improve readability, uses MOZ_TRY
and other checking macros wherever possible to simplify error handling and
replaces the ObserverRef class with the more generic nsMaybeWeakPtr class.
This cuts away some code and halves the amount of memory needed to store an
event listener. The external behavior is almost unchanged save for some error
codes which are now more specific.

This is needed for bug 1500926. It takes the approach of taking a JSFlatString

This lets us avoid re-encoding strings when performing lookups, which can be
advantageous.
Only ASCII strings are supported by this handler, and wide strings are hashed

This commit adds a scroll origin, nsGkAtoms::relative, which can be used to
mark main thread scrolling that can be combined with a concurrent APZ scroll.
The behavior of this is controlled by a pref, apz.relative-update. This pref
is initially activated and is intended as an aid to narrowing down causes
of regressions for users in bug reports.
Relative scroll updates work by tracking the last sent or accepted APZ
scroll offset. This is sent along with every FrameMetrics. Additionally,
a flag is added to FrameMetrics, mIsRelative, indicating whether the
scroll offset can be combined with a potential APZ scroll. When this
flag is set, AsyncPanZoomController will apply the delta between the sent
base scroll offset, and sent new scroll offset.
This flag is controlled by the last scroll origin on nsGfxScrollFrame. The
new origin, `relative`, is marked as being able to clobber APZ updates,
but can only be set if all scrolls since the last repaint request or
layers transaction have been relative.

In regen_atoms.py:
- There is now only one link name per platform: nsGkAtoms::sAtoms[].

- And the `atom!` macro for each atom indexes into nsGkAtoms::sAtoms[] using

but overlooked it.

Static atom registration is a bit of a mess. NS_InitAtomTable() calls
nsGkAtoms::RegisterStaticAtoms(), which calls NS_RegisterStaticAtoms(); i.e. we
go from nsAtomTable.cpp to nsGkAtoms.cpp and back.
(And NS_RegisterStaticAtoms() is declared in a .cpp file, not a .h file!)
This commit makes NS_InitAtomTable() a friend of nsGkAtoms, so NS_InitAtomTable
can see nsGkAtoms's atoms array directly, thus removing the need for
NS_RegisterAtomTable() and nsGkAtoms::RegisterStaticAtoms().
This commit also removes an out-of-date part of a comment from XPCOMInit.cpp.

nsGkAtoms.h has a big comment explaining how static atom definitions get
expanded by macros. This comment was very useful when there were multiple
sources of static atoms and their definitions used macros a lot. But bug
1482782 combined all the static atom sources into nsGkAtoms and removed a lot
of macro use. So now the comment is now something of a hindrance, duplicating
quite a bit of the code (and not entirely accurately).
This commit removes the big comment, and moves the still-useful parts inline
with the code. This makes things much easier to follow.
This commit also reformats some of the remaining macros so they are easier to
read.

Everything that goes in a PLDHashtable (and its derivatives, like
nsTHashtable) needs to inherit from PLDHashEntryHdr. But through a lack
of enforcement, copy constructors for these derived classes didn't
explicitly invoke the copy constructor for PLDHashEntryHdr (and the
compiler didn't invoke the copy constructor for us). Instead,
PLDHashTable explicitly copied around the bits that the copy constructor
would have.
The current setup has two problems:
1) Derived classes should be using move construction, not copy
construction, since anything that's shuffling hash table keys/entries
around will be using move construction.
2) Derived classes should take responsibility for transferring bits of
superclass state around, and not rely on something else to handle that.
The second point is not a huge problem for PLDHashTable (PLDHashTable
only has to copy PLDHashEntryHdr's bits in a single place), but future
hash table implementations that might move entries around more
aggressively would have to insert compensation code all over the
place. Additionally, if moving entries is implemented via memcpy (which
is quite common), PLDHashTable copying around bits *again* is
inefficient.
Let's fix all these problems in one go, by:
1) Explicitly declaring the set of constructors that PLDHashEntryHdr
implements (and does not implement). In particular, the copy
constructor is deleted, so any derived classes that attempt to make
themselves copyable will be detected at compile time: the compiler
will complain that the superclass type is not copyable.
This change on its own will result in many compiler errors, so...
2) Change any derived classes to implement move constructors instead of
copy constructors. Note that some of these move constructors are,
strictly speaking, unnecessary, since the relevant classes are moved
via memcpy in nsTHashtable and its derivatives.
