When updating notification counts, we already called User::invalidateCache(),
which bumps the local user's touched timestamp, which is taken into
account by OutputPage when computing the last-modified timestamp of the response.
However, this only works for one wiki, while the changed global count
needs to be displayed on every wiki. To accomplish this, track the
timestamp of the last update in NotifUser, and hook it into
OutputPageCheckLastModified.

We were using the local user ID instead, which is not the
same on every wiki, which caused strange cache staleness
and pollution behavior.
Run sets through a wrapper function (gets were already wrapped)
so we can update the instance cache and deal with uncomputable
cache keys in one place. A global cache key may be uncomputable
if we fail to obtain the user's global user ID (users aren't
supposed to be unattached, but some are).
Also bump the cache version to get rid of polluted cache entries.
Bumping this version number was probably a good idea anyway,
with all the recent changes.

Previously, getNotificationCount() only looked at local notifications,
and foreign notifications were added in separately by getMessageCount()
and getAlertCount(). This didn't make any sense and resulted in
counter-intuitive things like I4d49b543.
Instead, add a $global flag to getNotificationCount(). If $global=false,
the local count is returned as before, but if $global=true, the
global count (=local+foreign) is returned. If $global is omitted,
the user's cross-wiki notification preference determines which is returned.

the same issues.

Despite claiming to be about categories, $wgEchoDefaultNotificationTypes
was actually configuring both categories and types (which go inside
categories).
For example, 'thank-you-edit' is a type, but 'emailuser' is both
a category and a type (when used as a category, this has special
effects at Special:Preferences).
Since types and categories can and sometimes do have the same names,
this leaves no way to properly and clearly configure them. It also
makes it difficult to document what is going on (as required by
T132127).
Split into three variables:
$wgDefaultNotifyTypeAvailability - Applies unless overriden
$wgNotifyTypeAvailabilityByCategory - By category; this can be and is
displayed at Special:Preferences
$wgNotifyTypeAvailabilityByNotificationType - By type; this cannot
be displayed at Special:Preferences. To avoid confusing the user,
we introduce a restriction (which was previously followed in practice,
AFAICT) that types can only be overridden if the category is not
displayed in preferences.
Otherwise, it can look to the user like a category is on/off, but the
types within might have the opposite state.
Due to this configuration change, this is a breaking change, and needs
coordinated deployments.
This also lays the groundwork for T132127
Also change terminology to consistently use "notify type" for web/email.
It was mixing between that and output format (which unfortunately

Both in the order of the cross-wiki bundles themselves, and
in the message in the notification body.
ForeignNotifications tracks timestamps per wiki per section,
and exposes these through getWikiTimestamp(). ApiEchoNotifications
adds these timestamps to the sources manifest, and also sorts
the list of wikis by timestamp (it'd be nicer to do this in
ForeignPresentationModel instead, but then we'd have to create a new
ForeignNotifications instance which causes a duplicated DB query).
NotificationsModel receives the timestamp for its wiki as its
fallback timestamp, and makes getTimestamp() return this value
during the pre-population phase. This causes its parent to
automatically sort it correctly.
Because the timestamp of a wiki depends on the section (alerts vs messages),
we can't put it in the global sources manifest at the top level
of the API response. Instead, get rid of this global sources
manifest and put all the sources data in the foreign notifications
directly. This allows us to specify different timestamps, and also
allows us to get rid of code in EchoApi that was already remapping
the API response to this format.

The previous implementation did the following weird things:
* Stripped tags before parsing
* Stripped templates before parsing using a hacky while loop
that bails after ten attempts
* Decoded entities using htmlspecialchars_decode(), while
html_entity_decode() makes more sense
* ...which meant it had to manually convert   back
to spaces, which is not necessary if you use html_entity_decode()
* Removed any single braces ('{' and '}') from the output
* Rejected the entire output if there were any entities left,
which is fairly likely since htmlspecialchars_decode()
only decodes a few of them
Instead of all this, just parse, strip tags, decode entities
(all of them, not just a few), trim and truncate. In particular,
don't strip templates, because we use getTextSnippet() in mention
notifications, which look weird when {{ping}} templates are stripped.

Using wiki names in the header is problematic because the messages
we were using weren't designed to be used in a sentence, only in headings.
This removes the wiki names from the sentence in the header, and

Current situation: cross-wiki can be enabled on certain wikis &
disabled on others.
Code used to check if cross-wiki was enabled before fetching the
status of unread messages on foreign wikis. However, it would then
write that result to a shared memcached key.
The cross-wiki check should not happen before data is stored to
cache: what is stored should always be for all wikis. Only when
we fetch it, should we check if cross-wiki is enabled. And if it's
not, we can't use the cross-wiki data - we have to hack around it

Right now, if certain users should be excluded, that would have
to be part of the user-locators already. This is annoying because
it's hard to write "generic" user locators when you want to exclude
just a couple of people in certain cases.
In Flow, for example, we have user-locators for users watching a
board or topic. We don't want to send the notification to people
that have also been mentioned in that post (they'll get a separate
notification). We could build that exception into those
user-locators, but then we couldn't re-use them in other places...
This basically means we couldn't use EchoUserLocator::locateUsersWatchingTitle,
we would have to roll our own that also excludes mentioned users.
Instead, this lets you add 'user-filters' (that functionality
actually exists already, but is not currently exposed), which
lists users to not send the notification to, even though they could
be in a user-locator.

While we could change the frontend to use the unix timestamp format, I don't see
any reason not to also include the MW format in utc. Frontend can now easily use
that.
Also fixed creation of the moment object. The timestamp was created as UTC, but
the way it got there was wrong: it expects the timezone offset (Z) to be

which was fine, but confusing). I removed the 'Z' and forced it to be

Presentation models that display the number of bundled notifications
typically group these by a property like agent or page ID. For example,
every edit someone makes to a user talk page generates an event,
so there could be 5 edit-user-talk events by only 2 distinct users;
in that case we want to display "Foo and 1 other user left a message",
not "Foo and 4 other users".
With this change, a presentation model that wants such behavior
can pass a callback to getBundleCount() that retursn the user ID, which
will cause getBundleCount() to return the number of distinct
users rather than the total number of notifications.

should not be making database queries. But the API it provides
is what we want and will be supported even if the backend
implementation is changed.

We should probably merge this ASAP now that a lot of presentation
models still have to be implemented. There's a bit of B/C code that
will take care of the previous format, but it would be nice to be
able to remove that soon.
Meanwhile I've also changed getPrimaryLink to follow the same format.

This implements a backend layer and database storage for tracking what
wikis a user has unread notifications on. It is not yet exposed via any
API.
Whenever the notification counts on the local wiki are reset, a deferred
update is queued to also update the central database table.

Instead of relying on the frontend to render, this enables the frontend
to do it.
The API will now accept a new format: 'model', which is basically the
presentation model's data in json format.
Some of the render code is currently only in the backend (e.g. get icon
path from icon type) so other api formats will stay available. At some
point, however, we may be able to kill those.

It's basically impossible for DatabaseBase::select() to return false now
that ignoreErrors() is protected. So always return an array so callers
don't have to worry about false.
And remove a test that checked the result if DatabaseBase::select() did
return false.

`getMessageWithAgent` is used by `getHeaderMessage` is can
be reused by other presentation models who need the
agent in their body message.

Since EchoEventPresentationModel::canRender can reject notifications,
its result should no longer be used for infinite scroll.
Current code checks if the amount of to-be-rendered data exceeds what
we need to display, but if we reject some notifications that may no
longer be the case, even though there is more data still.

getTextSnippet() has a `Language` type hint that will fatal if $wgLang
is a StubUserLang object, so make sure we unstub it if nothing else
already has.

Wikis can customize the 'notification-welcome-link' to a page title
(like "Project:Welcome" for example) and the "Welcome!" notification new
users receive will have a primary link to that page.

Because 'welcome' doesn't.
Returning `false` indicates that there is no link, and the
FlyoutFormatter was updated accordingly.

This seems better for availability than stopping the world
and rolling everything back (or just throwing post-commit
errors that didn't stop the original change anyway).

The conversion of EchoEvent into a EchoEventPresentationModel is now
done by EchoFlyoutFormatter, instead of having each subclass do it. It
also does the canRender() check so subclasses don't need to worry about
it.
The subclasses no longer have access to the underlying EchoEvent object,
so the timestamp is exposed in EchoEventPresentationModel.
