Currently VarCache prefs are setup in two parts:
- The vanilla pref part, installed via a data file such as all.js, or via an
API call.
- The VarCache variable part, setup by an Add*VarCache() call.
Both parts are needed for the pref to actually operate as a proper VarCache
pref. (There are various prefs for which we do one but not the other unless a
certain condition is met.)
This patch introduces a new way of doing things. There is a new file,
modules/libpref/init/StaticPrefList.h, which defines prefs like this:
> VARCACHE_PREF(
> "layout.accessiblecaret.width",
> layout_accessiblecaret_width,
> float, 34.0
> )
This replaces both the existing parts.
The preprocessor is used to generate multiple things from this single
definition:
- A global variable (the VarCache itself).
- A getter for that global variable.
- A call to an init function that unconditionally installs the pref in the
prefs hash table at startup.
C++ files can include the new StaticPrefs.h file to access the getter.
Rust code cannot use the getter, but can access the global variable directly
via structs.rs. This is similar to how things currently work for Rust code.
Non-VarCache prefs can also be declared in StaticPrefList.h, using PREF instead
of the VARCACHE_PREF.
The new approach has the following advantages.
+ It eliminates the duplication (in all.js and the Add*VarCache() call) of the
pref name and default value, preventing potential mismatches. (This is a real
problem in practice!)
+ There is now a single initialization point for these VarCache prefs.
+ This avoids need to find a place to insert the Add*VarCache() calls, which
are currently spread all over the place.
+ It also eliminates the common pattern whereby these calls are wrapped in a
execute-once block protected by a static boolean (see bug 1346224).
+ It's no longer possible to have a VarCache pref for which only one of the
pieces has been setup.
+ It encapsulates the VarCache global variable, so there is no need to declare
it separately.
+ VarCache reads are done via a getter (e.g. StaticPrefs::foo_bar_baz())
instead of a raw global variable read.
+ This makes it clearer that you're reading a pref value, and easier to
search for uses.
+ This prevents accidental writes to the global variable.
+ This prevents accidental mistyping of the pref name.
+ This provides a single chokepoint in the code for such accesses, which make
adding checking and instrumentation feasible.
+ It subsumes MediaPrefs, and will allow that class to be removed. (gfxPrefs is
a harder lift, unfortunately.)
+ Once all VarCache prefs are migrated to the new approach, the VarCache
mechanism will be better encapsulated, with fewer details publicly visible.
+ (Future work) This will allow the pref names to be stored statically, saving
memory in every process.
The main downside of the new approach is that all of these prefs are in a
single header that is included in quite a few places, so any changes to this
header will cause a fair amount of recompilation.
Another minor downside is that all VarCache prefs are defined and visible from
start-up. For test-only prefs like network.predictor.doing-tests, having them
show in about:config isn't particularly useful.
The patch also moves three network VarCache prefs to the new mechanism as a
basic demonstration. (And note the inconsistencies in the multiple initial
values that were provided for
network.auth.subresource-img-cross-origin-http-auth-allow!) There will be
numerous follow-up bugs to convert the remaining VarCache prefs.

All prefs that need to be sent to a new content process are now put into the
shared memory segment, and they are identified by the pref name instead of an
index into a list. The old IPC used at process startup (in XPCOMInitData) is
removed.
Benefits:
- It removes the need for the early prefs list
(dom/ipc/ContentProcesses.{h,cpp}) and the associated checking, which is ugly
and often trips people up (e.g. bug 1432979, bug 1439406).
- Using prefnames instead of indices fixes some fragility (fixing bug 1419432).
- It fixes the problem of early prefs being installed as unlocked default

On Android, GeckoEditableSupport has already dispatched eKeyDown event and

Historically we built all our binaries in directories in the objdir, then
symlinked them into dist/bin. Some binaries needed to be copied instead
so that certain relative path lookups work properly, so we resorted to
sprinkling `NSDISTMODE=copy` around Makefiles.
This change makes it so we build PROGRAMs (not any other sort of targets)
directly in dist/bin instead. We could do the same for our other targets
with a little more work.
There were several places in the tree that were copying built binaries to
some other place and needed fixup to match the new location of binaries.
On Windows pdb files are left in the objdir where the program was
originally linked. symbolstore.py needs to locate the pdb file both to
determine whether it should dump symbols for a binary and also to copy
the pdb file into the symbol package. We fix this by simply looking for
the pdb file in the current working directory if it isn't present next
to the binary, which matches how we invoke symbolstore.py.

This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
a short-lived, anonymous, shared memory segment that is used to pass the early
prefs.
Removing the bloat from the command line is nice, but more important is the
fact that this will let us pass more prefs at content process start-up, which
will allow us to remove the early/late prefs split (bug 1436911).
Although this mechanism is only used for prefs, it's conceivable that it could
be used for other data that must be received very early by children, and for
which the command line isn't ideal.
Notable details:
- Much of the patch deals with the various platform-specific ways of passing
handles/fds to children.
- Linux and Mac: we use a fixed fd (8) in combination with the new
GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
won't close the fd).
- Android: like Linux and Mac, but the handles get passed via "parcels" and
we use the new SetPrefsFd() function instead of the fixed fd.
- Windows: there is no need to duplicate the handle because Windows handles
are system-wide. But we do use the new
GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
inheritable handles. We also ensure that list is processed on all paths
(MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
that the handles are marked as inheritable. The handle is passed via the
-prefsHandle flag.
The -prefsLen flag is used on all platforms to indicate the size of the
shared memory segment.
- The patch also moves the serialization/deserialization of the prefs in/out of
the shared memory into libpref, which is a better spot for it. (This means
Preferences::MustSendToContentProcesses() can be removed.)

This retains support for installing unpacked dictionaries, since Hunspell only
supports loading dictionaries from ordinary filesystem paths.
Unpacked extensions are no longer supported on production, except during
development. WebExtensions have no support for the unpacked flag at all, and
specially signed legacy extensions are forbidden from using it, so there's no
point in maintaining support for this install code. Or, more importantly, for
running a nearly complete duplicated set of tests in order to exercise it.

image.animated.decode-on-demand.threshold-kb is the maximum size in kB
that the aggregate frames of an animation can use before it starts to
discard already displayed frames, and redecode them as necessary. The
lower it is set to, the less overall memory we will consume at the
expense of execution time for as long as the tab with the animation(s)
above the threshold are kept open.
image.animated.decode-on-demand.batch-size is the minimum number of
frames we want to have buffered ahead of an animation's currently
displayed frame. The decoding will request this number of frames at a

We instead add a templated method NS_MutatorMethod that returns a std::function<nsresult(nsIURIMutator*)> which Apply then calls with mMutator as an argument.
The function returned by NS_MutatorMethod performs a QueryInterface, then calls the passed method with arguments on the result.

The image decoding thread pool can grow to be quite large, up to 32
threads, depending on the number of processors on the system. If the
user is not actively browsing, these threads are occupying resources
which could be reused elsewhere. After the timeout period, it will
release up to half of the threads in the pool.

No Nightly testers don't report new compatibility issue. Additionally, if we
make Firefox use <div> as defaultParagraphSeparator in release build, web
services may stop supporting our current behavior quickly because they can
get rid of hack for us. Therefore, we should do this in the cycle of Gecko 60
which is next ESR. If we did this later, ESR users may have become not to be
able to use existing web services suddenly immediately after we did this in 61
or 62. We should avoid this bad scenario.

This has two advantages. First, it reduces memory usage, as per the following
calculation.
64-bit:
- Old sizes:
- sizeof(Pref) = 32
- New sizes:
- sizeof(PrefEntry) = 16
- sizeof(Pref) = 32
- Change:
- -16 per empty slot in the hash table
- +16 per used slot
- A win if less than half the table slots are used
32-bit
- Old sizes:
- sizeof(Pref) = 20
- New sizes:
- sizeof(PrefEntry) = 8
- sizeof(Pref) = 16
- Change:
- -12 per empty slot in the hash table
- +4 per used slot in the hash table
- A win if table is < 75% full
Table size:
- The table is currently less than half full: ~3100 used out of 8192 slots.
- The table is always <= 75% full, because that's the max load factor (for
non-gigantic tables).
- Therefore it's a win for both cases.

The "hash-table" values drop by more than the size of the new "pref-values"
value.
On 64-bit, this reduces memory usage per process by 30--40 KB. On 32-bit, the
number is slightly more.
The second major advantage of this change is flexibility -- it opens up the
possibility of different Pref objects being stored in different way. For
example, static Prefs could be stared statically, letting them be shared
between processes so long as they don't change (see bug 1437168).

This construct is nicer than NS_INTERFACE_MAP_BEGIN and assures the
reader there's no weirdness in the QI implementation. This change does
mean that PGO doesn't get an opportunity to measure the frequency of
which interfaces are QI'd most often. I think this is probably an OK
tradeoff to make, given the prevalence of NS_IMPL_QUERY_INTERFACE
elsewhere in the codebase.
The one thing we have to ensure with this change is that the ambiguous
QI to nsISupports uses the proper class after the change. The
NS_IMPL_QUERY_INTERFACE macro chooses the first interface listed to
disambiguate the cast to nsISupports.

Preferences methods.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

The prefs parser has two significant problems.
- It doesn't separate tokenizing from parsing.
- It is implemented as a loop around a big switch on a "current state"
variable.
As a result, it is hard to understand and modify, slower than it could be, and
in obscure cases (involving comments and whitespace) it fails to parse what
should be valid input.
This patch replaces it with a recursive descent parser (albeit one without any
recursion!) that has separate tokenization. The new parser is easier to
understand and modify, more correct, and has better error messages. It doesn't
do error recovery, but that would be much easier to add than in the old parser.
The new parser also runs about 1.9x faster than the existing parser. (As
measured by parsing greprefs.js's contents from memory 1000 times in
succession, omitting the prefs hash table construction. If the table
construction is included, it's about 1.6x faster.)
The new parser is slightly stricter than the old parser in a few ways.
- Disconcertingly, the old parser allowed arbitrary junk between prefs
(including at the start and end of the prefs file) so long as that junk
didn't include any of the following chars: '/', '#', 'u', 's', 'p'. I.e.
lines like these:
!foo@bar&pref("prefname", true);
ticky_pref("prefname", true); // missing 's' at start
User_pref("prefname", true); // should be 'u' at start
would all be treated the same as this:
pref("prefname", true);
The new parser disallows such junk because it isn't necessary and seems like
an unintentional botch by the old parser.
- The old parser allowed character 0x1a (SUB) between tokens and treated it
like '\n'.
The new parser does not allow this character. SUB was used to indicate
end-of-file (*not* end-of-line) in some old operating systems such as MS-DOS,
but this doesn't seem necessary today.
- The old parser tolerated (with a warning) invalid escape sequences within
string literals -- such as "\q" (not a valid escape) and "\x1" and "\u12"
(both of which have insufficient hex digits) -- accepting them literally.
The new parser does not tolerate invalid escape sequences because it doesn't
seem necessary and would complicate things.
- The old parser tolerated character 0x00 (NUL) within string literals; this is
dangerous because C++ code that manipulates string values with embedded NULs
will almost certainly consider those chars as end-of-string markers.
The new parser treats NUL chars as end-of-file, to avoid this danger and
because it facilitates a significant optimization (described within the
code).
- The old parser allowed integer literals to overflow, silently wrapping them.
The new parser treats integer overflow as a parse error. This seems better,
and it caught existing overflows of places.database.lastMaintenance, in
testing/profiles/prefs_general.js (bug 1424030) and
testing/talos/talos/config.py (bug 1434813).
The first of these changes meant that a couple of existing prefs with ";;" at
the end had to be changed (done in the preceding patch).
The minor increase in strictness shouldn't be a problem for default pref files
such as greprefs.js within the application (which we can modify), nor for
app-written prefs files such as prefs.js. It could affect user-written prefs
files such as user.js; the experience above suggests that integer overflow and
";;" are the most likely problems in practice. In my opinion, the risk here is
acceptable.
The new parser also does a better job of tracking line numbers because it (a)
treats "\r\n" sequences as a single end-of-line marker, and (a) pays attention
to end-of-line sequences within string literals.
Finally, the patch adds thorough tests of both valid and invalid syntax.

UI Events declares that keypress event should be fired when the keypress event
causes some text input. However, we're keeping our traditional behavior for
historical reasons because our internal event handlers (including event
handlers of Thunderbird) handles keypress events for any keys. Therefore,
for minimizing the side effect, we should stop kicking keypress event handlers

Provides an optional resolver mechanism for Firefox that allows running
together with or instead of the native resolver.
TRR offers resolving of host names using a dedicated DNS-over-HTTPS server
(HTTPS is required, HTTP/2 is preferable).
DNS-over-HTTPS (DOH) allows DNS resolves with enhanced privacy, secure
transfers and improved performance.
To keep the failure rate at a minimum, the TRR system manages a dynamic
persistent blacklist for host names that can't be resolved with DOH but works
with the native resolver. Blacklisted entries will not be retried over DOH for
a couple of days. "localhost" and names in the ".local" TLD will not be
resolved via DOH.
TRR is preffed OFF by default and you need to set a URI for an available DOH
server to be able to use it. Since the URI for DOH is set with a name itself,
it may have to use the native resolver for bootstrapping. (Optionally, the
user can set the IP address of the DOH server in a pref to avoid the required
initial native resolve.)
When TRR starts up, it will first verify that it works by checking a
"confirmation" domain name. This confirmation domain is a pref by default set
to "example.com". TRR will also by default await the captive-portal detection
to raise its green flag before getting activated.
All prefs for TRR are under the "network.trr" hierarchy.

This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

This commit adds a paint worker thread pool to PaintThread, and dispatches
tiled paints to it. The thread pool is only created if tiling is enabled,
and its size is set by 'layers.omtp.paint-workers' and defaults to 1. If
-1 is specified, it will be sized to 'max((cpu_cores * 3) / 4, 1)'.
The one tricky part of dispatching tiled paints to a thread pool is the
AsyncEndLayerTransaction message that must execute once all paints are
finished. Previously, this runnable would be queued after all the paints
had been queued, ensuring it would be run after they had all completed.
With a thread pool, there is no guarantee. Instead this commit, uses
a flag on CompositorBridgeChild to signify whether all of the paints
have been queued ('mOutstandingAsyncEndLayerTransaction'), and after
every tiled paint it is examined to see if that paint was the last
paint, and if it is to run AsyncEndLayerTransaction. In addition,
if the async paints complete before we even mark the end of the
layer transaction, we queue it like normal.
The profiler markers are also complicated by using a thread pool.
I don't know of a great way to keep them working as they are per
thread, so for now I've removed them. I may have been the only
one using them anyway.

This patch introduces three keyed histograms:
- PREFERENCES_FILE_LOAD_SIZE_B
- PREFERENCES_FILE_LOAD_NUM_PREFS
- PREFERENCES_FILE_LOAD_TIME_US
They are all keyed on the prefs file's name; in my local Linux64 build there
are 13 such files.
Because prefs start up earlier than telemetry, we have to save the measurements
and then pass them to telemetry later.

New content processes get prefs in three ways.
- They read them from greprefs.js, prefs.js and other such files.
- They get sent "early prefs" from the parent process via the command line
(-intPrefs/-boolPrefs/-stringPrefs).
- They get sent "late prefs" from the parent process via IPC message.
(The latter two are necessary for communicating prefs that have been added or
modified in the parent process since the file reading occurred at startup.)
We have some machinery that detects if a late pref is accessed before the late
prefs are set, which is good. But it has a big exception in it; late pref
accesses that occur early via Add*VarCache() and RegisterCallbackAndCall() are
allowed.
This exception was added in bug 1341414. The description of that bug says "We
should change AddBoolVarCache so that it doesn't look at the pref in the
content process until prefs have been received from the parent." Unfortunately,
the patch in that bug added the exception to the checking without changing
Add*VarCache() in the suggested way!
This means it's possible for late prefs to be read early via VarCaches (or
RegisterCallbackAndCall()) when their values are incorrect, which is bad.
Changing Add*VarCache() to delay the reading as bug 1341414 originally
suggested seems difficult. A simpler fix is to just remove the exception in the
checking and extend the early prefs list as necessary. This patch does that,
lengthening the early prefs list from ~210 to ~300. Fortunately, most (all?) of
the added prefs are ints or bools rather than strings, so it doesn't increase
the size of the command line arguments for content processes by too much.

This patch adds following Microsoft's IMEs into the black list which set
their open state to "closed" when input scope is set to IS_URL and sets
input scope for the URL bar to IS_DEFAULT.
Additionally, this adds a new pref to disable this hack because a lot of

they use tablet.
The new black listed IMEs:
- Microsoft Bopomofo
- Microsoft ChangJie
- Microsoft Phonetic
- Microsoft Quick
- Microsoft New ChangJie
- Microsoft New Phonetic
- Microsoft New Quick
- Microsoft Pinyin
- Microsoft Pinyin New Experience Input Style
- Microsoft Wubi

This patch moves us from using an old pref `general.useragent.locale`combined
with `intl.locale.matchOS` for retrieving user requested locale, to use a new
preference `intl.locale.requested` which stores a list of well-formed BCP47
language tags. If set to empty, the OS locales are used. If not set at all,
default locale is used.
We are also adding a piece of code to migrate from old to new system.

This code is used to detect too-early accesses of prefs in content processes.
The patch makes the following changes.
- New terminology: "early" prefs are those sent via the command line; "late"
prefs are those sent via IPC. Previously the former were "init" prefs and the
latter didn't have a clear name.
- The phase tracking and checking is now almost completely encapsulated within
Preferences.cpp. The only exposure to outside code is via the
AreAllPrefsSetInContentProcess() method, which has a single use.
- The number of states tracked drops from 5 to 3. There's no need to track the
beginning of the pref-setting operations, because we only need to know if
they've finished. (This also avoids the weirdness where we could transition
from END_INIT_PREFS back to BEGIN_INIT_PREFS because of the way -intPrefs,
-boolPrefs and -stringPrefs were parsed separately.)

Preferences::SetPreference() is used when setting prefs in the content process
from dom::Pref values that are passed from the parent process. Currently we
use the high-level Set*InAnyProcess() methods to do this -- basically the same
code path as sets done via the API -- but this has several problems.
- It is subtly broken. If the content process already has a pref of type T with
a default value and then we get a SetPreference() call that tries to change
it to type U, it will erroneously fail. In practice this never(?) happens,
but it shows that things aren't arranged very well.
- SetPreference() also looks up the hashtable twice to get the same pref if
both a default value and a user value are present in the dom::Pref.
- This happens in content processes, while all other pref set operations occur
in the parent process. This is the main reason we have the Set*InAnyProcess()
functions.
In short, the setting of prefs via IPC is quite different to the setting of
prefs via other means -- because it happens in content processes, and it's more
of a clobber that can set both values at once -- and so should be handled
differently.
The solution is to make Preferences::SetPreference() use lower-level operations
to do the update. It now does the hash table lookup/add itself, and then calls
the new Pref::FromDomPref() method. That method then possibly calls the new
PrefValue::FromDomPrefValue() method for both kinds of value, and overwrites
them as necessary. SetValueFromDom() is no longer used and the patch removes it.

High resolution, high framerate was disabled by default on old AMD cards on the provisio that it was bad. But this assumes that the CPU decoder could do it better.
This assumption appears fragile at best, as CPU with those old adapter are likely to be old and underpower to start with.
Chrome doesn't appear to restrict use of those cards to a given resolution.
So we disable this restriction, while making it user configurable.

Currently, you can create a pref that only has a user value, and then later
give it a default value with a different type. The entire pref is then recorded
as having this second type. This causes problems later when interpreting the
user value.
This patch makes SetValue() fail if it tries to set a default value whose type
differs from an existing user value. It also expands an existing test to cover
this case and some similar ones.
