The first patch for this enabled the contile feature by default which based on
the automated tests increased the number of inflations done in HomeActivity.
This patch comes to address that by allowing for up to 6 inflations as seen
reported as the actual count in tests.
It's easier to modify the explanation of the heuristics in code comments
rather than command line strings so I moved the failure explanations
into code comments, allowing me to simplify the test failure error messages.
We want this test to be self service for the fenix team so the meaning
of the documentation was updated. Additionally, we clarified why each
heuristic exists to make the test more accessible to self service.
This doesn't seem to be a high value test: increasing the view hierarchy
depth will only result in a performance problem on low end devices
if there is enough content on the new layer to cause the traversal to
take longer. It's more likely to result in a hard-to-workaround false
positive so we can remove it, like component init count.
This check doesn't seem high value because initializing a component
only indicates a performance problem if it's slow, which is not most
components, so it's likely to result in many false positives. To fix
the intermittent, we won't lose much if we remove it.
Compared with my local runs, CI sees +1 runBlockingIncrement calls so seems to
take other code paths. As such, we search for a range of rather than a single
value. The main downside I can think of is this could make the test trickier to
debug but we can wait and see if that's a problem in practice before taking
action on it.
This test wasn't running in CI
https://github.com/mozilla-mobile/fenix/issues/20386 so we changed the
CI configuration so that it will. However, the test was then failing so
this is the revision that unignores the test.
I wonder if componentInit count is useful - it seems like it'd cause
more false positives than not - but I figure we can leave it in and see
how it goes.
* For #16900: implement async navgraph inflation
For #16900: removed nav graph from xml
For #16900: inflate navGraph programatically
For #16900: Made NavGraph inflation asynchronous
For #16900: Changed to block with runBlocking
For #16900: Refactored blocking call into a function
For 16900: NavGraph inflation is now async
We now attach the nav graph (or check if its attached) on every nav call ( an extension function for NavController).
This is done by checking the value of the job stored in PerfNavController.map which keeps track of the job with the NavController as a Key.
If the job hasn't been completed, it will block the main thread until the job is done. The job itself is responsible for attaching the navgraph
to the navcontroller (and the inflation of the latter too)
For 16900: rebased upstream master
For 16900: Rebase on master
For #16900: Fixed Async Navgraph navigation per review comments.
1)The Asynchronous method is now found in NavGraphProvider.kt. It creates a job on the IO dispatcher
2)The Job is tracked through a WeakHashMap from Controller --> NavGraph
3)The Coroutine scope doesn't use MainScope() anymore
4)The Coroutine is cancelled if the Activity is destroyed
5)The tests mockk the blockForNavGraphInflation method through the FenixReoboelectricTestApplication instead of calling the mock every setup()
For #16900: inflateNavGraphAsync now takes navController
For #16900: Pass lifecycleScope to NavGraphProvider
For #16900: removed unused mock
For #16900: Added linter rules for navigate calls
We need linting rules to make sure no one calls the NavController.navigate() methods
For #16900: Added TestRule to help abstract the mocks in the code
For 16900: Fix linting problems
For #16900: Cleaned duplicated code in tests
For #16900: cleaned up NavGraphTestRule for finished test
For #16900: had to revert an accidentally edited file
For #16900: rebased master

* For #16373: Added performance Inflater to counter # of inflations
This class is quite straight forward. The only thing that I have to point out is the onCreateView method. It usually
calls its super if you don't override it. The problem with that is that the super.onCreateView actually uses
android.view. as a prefix for the XML element it tries to inflate. So if we have an element that isn't part
of that package, it'll crash. As I said in the code, a good example is ImageButton. Calling android.view.ImageButton
will make the app crash. The method is implemented the same way that PhoneLayoutInflater does (Another example
is the AsyncLayoutInflater)
* For #16373: Added test for PerformanceInflater
This test got quite awkward / complicated fast. I wanted to test the to make sure we don't break *any* of our layouts
and to do so, I decided to just retrieve all our XML in our /res/layout folder. However, this gets quite a bit outside of a unit test scope.
The point was to get every layouts and get their LayoutID through the resources using the testContext we have. It gets even weirder, since some
of the XML tags have special implementation in android. One of them is the <fragment> tag. That tag actually is inflated by the OS using the Factory2
that the Activity.java implements. In order to get around the fragment issue, we just return a basic FrameLayout since the system LayoutInflater doesn't deal
won't ever get a <fragment> tag to inflate. Another issue was the <merge> tag. In order to inflate those, you need 1) a root view and 2) attach your view to it.
In order to be able to test those layouts file, I had to create an empty FrameLayout and use it as the root view for testing. Again, I know this is beyond the spirit of a unit test but if we use this inflater, I think it should make sure that no layouts are broken by it.
* For #16373: Overrode getSystemService to return PerformanceInflater
This allows PerformanceInflater to be called in every inflation to keep track of the number of inflations we do.
* For #16373: Added UI test for # of inflations
* For #16373: Lint fix
* For #167373: Changed the LayoutInflater cloneInContext to take this instead of inflater
The inflater parameter is set on the first call from the OS from the Window object. However, the activity itself sets multiple factories on the inflater
during its creation (usually through AppCompatDelegateImpl.java). This means that, once we initially set the inflater with a null check, we pass an inflater
that has no factory initially. However, since we keep a reference to it, when cloneInContext was called, it cloned the inflater with the original inflater
which didn't have any factories set up. This meant that the app would crash on either browserFragment creation or any thing that required appCompat (such as
ImageView and ImageButton). Now, passing itself with a cloneInContext means we keep all the factories initially set by the activity or the fragment.
* For #16373: Fixed code issues for PR. No behavior change
* For #16373: fixed some code nits
