Now that the Glean Dictionary (https://dictionary.telemetry.mozilla.org)
has hit production, our guidance is to move away from generating
metrics.md files. The Glean Dictionary is a better solution for this task
for a couple of reasons:
1. The Glean Dictionary contains a complete reference of all metrics
and pings sent by an application (not just those defined in the
application itself, as is the case with the markdown documentation)
2. The Glean Dictionary provides additional context and links beyond
what is provided by the documentation (for example, information on
how to access metric information via BigQuery or GLAM) as well as
annotations provided by data scientists in the course of analyzing data
(see, for example, the commentary section for:
https://dictionary.telemetry.mozilla.org/apps/fenix/metrics/metrics_search_count).
This should also reduce some of the churn/burden on people when
they submit PRs, as there is no longer any need to update metrics.md
as a part of them.
For #18857 [Telemetry] Send a Glean event when users change their default browser
For #18855 [Telemetry] Send an event when users open the toolbar menu
For #18851 [Telemetry] Send an event when users click on the "set as default browser" entry in the toolbar menu
The StartupActivityStateProvider uses an imperative implementation,
driven by callbacks, to set the state of the application. This is hard
to follow as you need to understand which callbacks will be called in
which order. For example, to make sense of an implementation like this,
COLD, WARM, AND HOT would likely need to be implemented in separate
ActivityLifecycleCallbacks.
I feel the StartupStateProvider is an improvement because it leverages
the StartupActivityLog to query a linear state for a more understandable
implementation. Furthermore, it seems accessible to write COLD, WARM,
and HOT in the same class because they can all be approached the same
way.
Lower Android versions don't offer the possibility of opening system settings
at a specific preference. In this cases we already shown a sumo article
detailing the manual steps each user is expected to perform to change the
system set default browser.
Hopefully this will help us understand behavior of the
`application_on_create` probe, specifically that it seems to take longer
in telemetry than in does locally compared to `home_activity_on_create`
(comparing the medians to local runs)..
While we could easily move this into the metrics ping, it's better to
leave it in the other ping because it's less work and because (I think)
we'll be better able to match `framework_secondary` values to the clock
ticks if we combine them in the same ping.
We do this in order to make it easier to analyze in GLAM: see the metric
descriptions for more details.
Additionally, we change the time unit to milliseconds to make it easier
to analyze in GLAM.
* For #17418 - Adds channel "ts" to TrackKey
This is used to track if the `InContentTelemetry` is a result of the user using the Google Top Site. It looks for `&channel=ts` within the uri.
* For #17418 - Adds TopSite PerformedSearch back in
* For #17418 - Check now looks for equality with GOOGLE_URL
* For #17418 - Adds test for topSite changes
