Two new events are added:
- "inactive_tabs_expanded" for when the inactive tabs section is expanded
- "inactive_tabs_collapsed" for when the inactive tabs section is collapsed
For tracking when an inactive tab is opened / closed I've repurposed the
existing tabs tray telemetry (since the functionality uses the same code)
- tabs_tray.opened_existing_tab
- tabs_tray.closed_existing_tab
to support an extra "source" key indicating the feature from which a tab was
opened or closed. The current values for this new key are:
- "Tabs tray" for when a tab was opened/closed from tabs tray
- "Inactive tabs" for when a tab was openes/closed from the Inactive tabs
section of the tabs tray.
This means no code will be generated by Kotlin Android Extensions for caching
views and also for @Parcelize annotated classes.
As recommended in the official documentation
https://developer.android.com/topic/libraries/view-binding/migration#gradle
we need to switch on using `kotlinx.parcelize.Parcelize` instead of
`import kotlinx.android.parcel.Parcelize`

This ensures that we do not attempt places initialization before
Megazord.init() finishes, and that touching BrowserStore does not
kick-off places initialization (due to the `cleanup` call being a
side-effect of creating metadata middleware, used as part of the
BrowserStore).
Glean initialization happens before initialize megazord, and it touches
core.store BrowserStore instance, kicking-off places initialization on
an IO thread (due to the cleanup call), which raced megazord
initialization on the main thread.
App init sequence is a bit of a mine-field, so this patch takes the easy
way out and doesn't attempt to re-order initialization sequence. Also,
initializing places as a side-effect of touching BrowserStore was also,
clearly, a bug.
This allows recording part of history metadata to ride the trains.
The UI features are still guarded by the secret settings flag (or,
enabled on debug builds).
The bug here was that we'd try to record `now - 0` as a viewTime delta.
This isn't just an obviously wrong value to record, but it will also
overflow our storage - we'll end up with a value on disk that doesn't
fit into an i32, but HistoryMetadata.total_view_time is i32 in our Rust
struct. Once that happens, reads that touch this bad row will result in
an overflow and a crash.
For details on the root cause, see the commit. We replaced the similar
proguard rules because:
- the key line was returning false instead of true
- the other line had the same outcome as the written code. I believe it
was a micro-optimization. Since perf seems fine without it, let's
remove it
I benchmarked this change on COLD MAIN first frame. We see an
improvement of 89ms:
- before: 1346ms
- after: 1257ms
This test seems to be hacking at the binding between Fenix and the
BrowserToolbar to simulate toolbar events passing to the Fenix
interactor.
This is rather clumsy test that relies on the magic working of mockk
instead of following a general unit testing strategy that would commonly
require the class to be re-written to allow for better testing instead.
It is far safer to remove this test since we are not guaranteeing
anything in it and instead we see intermittent failures that make us
lose more time.
So therefore.. 🔥
The expectation is that replacing `return` with `answers` will compute
the return value for the extension function again in order to avoid the
error, "no answer found for: Settings".
Theoretically, this should marginally decrease the duration of our unit
test suite. In my testing, for 1 iteration each (i.e. noise is very
possible), the duration changed from 9m 32s to 8m 21s – a 71s
improvement.

To identify tests that were running with robolectric that didn't need to
be, I removed the @RunWith(FenixRobo... from all relevant files:
sed -i '' "/@RunWith(FenixRobolectric/d" app/src/test/**/*.kt
I ran the tests and discovered which ones failed from the Classes tab of
the index.html test result file. Something like:
tests = document.querySelectorAll('table')[3].querySelectorAll('tr');
failureElements = tests.querySelectorAll('.failures');
// TODO: extract the test names
Then I copied these results to a text file and compared them to all the
files that had robolectric test runners to figure out which ones still
pass:
comm -1 -2 failures.txt changed_files.txt > robolectric_not_needed.txt
And undid the changes to the failing files:
for i in $(cat robolectric_not_needed.txt); do git checkout $i; done
Then I removed the import statements on those files:
for i in $(cut changed_files.txt); do sed -i '' "/import.*RunWith/d" $i; done
for i in $(cat changed_files.txt); do sed -i '' "/import.*RobolectricTestRunner/d" $i; done
