* For #11660:added prefetch for topsites
TopSites will be prefetched with observerOnce (wrapper around observerForever).
Also, the SessionControlView.update() is called right away instead of waiting from consumeFrom
in the HomeFragment.onCreateView() which will allow the UI to render all at once on its first
perform traversal
* Removed the submitList(null) since it retriggered a drawing on lower end device
for #7225, refactored and cleanup the branch.
for #7225, change strict mode policy only on main process.
for #7225, setting thread policy inside a seperate thread to keep it from getting overridden in activities.
for #7225 removed Handler().postAtFrontOfQueue as a solution due to unknown side effects. moved the enableStrictMode function to be static so we can reuse it.
for #7225 lint check
for #7225 created strict mode manager and moved enabledStrictMode function inside it.
for #7225 removed penalty death on network
for #7225 added allow disk access on thread for already existing violation
strict mode running in main process to see if it passes the gitlab check, will revert it if it doesnt
allowed diskread for super.onCreate for home activity
added comments for disk violation oncreate homeactivity
added fragment manager inside strictmode manager
allowed disk read for onboarding
allowed disk read for cachedTopSites
In order to hide the time it takes for the account manager to be initialized
(which always involves disk IO, and often network IO), let's kick it off
after "visual completeness".
This makes sure that for most users, by the time they interact with the account
manager-related functionality (e.g. in Settings), it's ready to go.
Also, for signed-in users, this will establish background sync workers.
This replaces the StartupTaskManager we had with a more general class.
New implementation is a thread-safe "gated task executor", which either
runs the task right away if it's marked as 'ready', or queries it to be
executed later on.
This ability to either execute or queue a task will be useful later on in the
commit series.
In order to eat the perceived performance costs, we initialize storage
once we're visually complete. This way, we're reducing chances of user performing
a UI action which will trigger storage init and delay said action.
As far as I can tell, we never actually exercise the a-s libraries in Fenix tests currently (this was one of the presumed reasons for having a direct dependency).
In a different branch I've started work on adding end-to-end tests, but currently that's blocked on trying to figure out to load native libraries in tests (somehow, fenix's setup is different than what we have in A-C, not yet clear to me in what way).
Another reason for a direct dependency (i think) is that we needed it to configure a `fenix` megazord. This could be solved via a `support-megazord-fenix` a-c component that provides the correct transient dependencies,
but we can also just switch to use the `full` megazord instead, which is essentially what fenix megazord is at this point. A-S team wants to remove the fenix megazord, so this will help. This is what this patch does.
In an early iteration of his patch on a beta build, I saw no improvement over
6 runs (Pixel 2):
- Before: 401.5ms
- After: 402.17ms
This may be attributed to noise in startup performance. However,
BrowsersCache disappears from profiles completely and results in
theoretical performance gains.
When using the StartupTimeline class (not landed yet), I see a 27.75ms
runtime improvement on beta builds after this patch.
This removes Fretboard. The goal is to reduce cold startup costs associated with loading the experiments on the main thread. We currently have two experiments frameworks in use and should only require one.
* For #220
- Added advanced header + locale settings item in the settings fragment
* For #220
- Added locale selection page with lib state + handling of locale changes
* For #220
- Removed registering for locale changes in the manifest, allow system
to restart activity in that scenario
* For #220
- Added unit tests for locale settings page
* For #220: fixed an outdated unit test

* For #7410: rewrite updateBookmarkFromObservableInput with coroutines
* For 7410: remove RxJava from project. :(
* For 7410: converted updateBookmarkFromTextChanges to Flow per review
This call will acquire a "write" lock at the storage layer (sqlite's reserved+),
which may interfere with migrations that run during startup as well (they need to
write to storage, and so also need to acquire a lock). If these operations clash,
we get a SQLITE_BUSY crash. For now, just disable the maintenance operation.
Thanks to the work of the team at application-services, it is possible
to asynchronously initialize the Http client and logger used by megazord
Use that power to hide the time necessary to complete this initialization
within the time that it takes to warmup the gecko runtime.
