The VisualEditorFeatureUsage instrument is a candidate for migration to
the Metrics Platform [0]. The first step of the migration is to log
events both using the Event Platform directly (i.e. via
mw.eventLog.submit()) and using the Metrics Platform client (i.e. via
mw.eventLog.dispatch()).
The Metrics Platform Client can mix in additional information -
so-called context attributes [1] - based on the stream configuration.
The majority of the default values mixed into each event are already
known to the Metrics Platform Client.
Note well that the Metrics Platform client will not log an event without
one or more streams being configured to receive that event. Therefore,
this change is a NOP.
An example stream configuration is given in [2].

In the new-page case, wgRevisionId will be 0 so it'll try looking for
parentRevId and the cast-to-int on an undefined will get us NaN. That
fails validation, so we should give one last fallback to 0.
It's _possible_ that we could instead make this an explicit check for
using wgRevisionId if it's anything not-undefined, but I'm not certain
about whether there are cases that wouldn't cover.

When opening the old wikitext editor, 'wgRevisionId' is always set to
0, and remains that way even if we switch to visual editor.
Elsewhere in the code, we handle this case by reading the revision ID
from the old wikitext edit form, so do that here as well. (This still
works after switching to visual editor.)

Similar to WikiEditor, allow the editing_session_id value to be
overriden through the editingStatsId query parameter. Also allow
server-side code to override the session ID by setting
wgWMESchemaEditAttemptStepSessionId in mw.config.
Only apply the override to the first session. Once a second init event
happens, discard the overridden editing_session_id and generate a fresh
one.

The EventLogging extension no longer uses these internal modules.
They were phased out as part of last year's "lightweight EventLogging"
project (detailed at T187207). Migration notes at T205744.
VisualEditor has migrated already, mostly. It still depended
on the existence of these module names for some condition guards.
* The subscriber for 'mwTimingHandler' was guarded by 'schema.EditAttemptStep',
but did not emit events of that schema. What 'mwTimingHandler' really
needs is the '*SamplingRate' variable for its call to 'inSample()'.
This previously worked because the variable and the schema are both
provided by the WikimediaEvents extension.
* The subscriber for 'activityHandler' had a separate schema guard. This
might suggest an intent for the code to silently degrade if WikimediaEvents
were to be changed to no longer supply the second schema, or for the code
to work for third-parties without WikimediaEvents if they register only
the schema. However, this subscriber too calls 'inSample()' and needs those
variables.
I've assumed for now that it is okay for these to all be guarded together.
Even if the schemas were to be removed and we were to forget updating this
code, the new EventLogging client degrades gracefully from this (no errors).

The EditAttemptStep schema doesn't have some of the fields we attempt to
submit, because we're generalizing and it only wants specific ones. Be more
selective about what we submit, so validation messages in the console will be
quiet.

The timing variable is a private closure variable containing an object
that tracks the timestamps of different events in the current cycle. The
duration variable is the result of using that information to compute the
difference between the current timestamp and the relevant anchor
timestamp. For the '_timing' property in the EventLogging data, duration
is the correct value, not timing.
(This is confusing and we should probably rename the timing variable.)

Respect the config var exported by WikimediaEvents that, if set to true,
forces oversampling. When oversampling, all events are logged even if
they would have been sampled out. The isOversample property is set to
true if the event was oversampled and would not otherwise have been
logged.

Instead of hard-coding the 6.25% sampling rate, allow it to be
controlled by the config variable in the WikimediaEvents extension
(which also defines the RL module for the Edit schema).
Also use sampling code from EventLogging so we can configure the
sampling rate as a number, rather than using a hex-digit based strategy.

ve.track tries to guess the platform, but it needs a loaded Target to do so,
and init happens before that.
Also, log a warning when this happens, in case it comes up again.
Bug: T203618
Change-Id: I35fa58a42cd247e01f3717c9ab3a10d8ea93a484
In Schema:Edit, all action timing durations (ready, loaded, saveAttempt etc.)
are defined as "time since the editor was initialised", which is internally
stored as the timestamp for the "init" action.
The 'init' action itself does not have a timing duratation, but the Edit schema
has a special case for it, definining it as "time since the page was loaded".
In actually, it isn't actually implemented as "time since the page loaded",
and I suspect that as such, this value is probably not used by EventLogging
consumers of the Edit schema. Or, it might be used, but doesn't represent
what the consumers think it does.
Presently, it uses the init time now() - mediaWikiLoadStart, which basically
means the time between the random point at which MediaWiki core JavaScript
finished executing which is quite variable in practice due to the race between
<script async> and browssing parsing/rendering of HTML. That is by design,
and is also why mediaWikiLoadStart is undocumented and internal, and actually
in the process of being removed.
After many iterations on this patch to try and approximate an alternative to
this undocumented variable, I came up with an alternative approach with DLynch
at the Hackathon, which is to simply not record this one timing value, but
preserve the behaviour of all the other timing values exactly as-is.
That is, keep the behaviour of storing `now()` as "init" when the editor
activates, and keep the behaviour of substracting "init" from all other action
times, but only don't report "init" itself to EventLogging (given its value
would be 0, which isn't useful).
