* MM-26203: Fix TestChannelStore//SearchAllChannels flake
Using random strings for channel names creates chances of collisions
when searching for specific strings.
We increase the search space increasing the size of the search string
to be searched. This reduces collisions and makes the tests more reliable.
For the "off-" family of tests, this probably needs more length. But
it would also need the tests to be changed slightly as the "off-" part
acts as a prefix. I accidentally stumbled upon it while running the test
50 times. Adding a "-" is probably good enough for now. We can revisit
if it fails again in CI.
* improved team_store tests too
* MM-24674 Update channel members by group to look at distinct autoTimezone and manualTimezone.
Instead of just doing a blanket distinct on the column since that returns more entries than expected
* Use JSON extract instead of parsing text
* Use single quotes in mysql query too
* Dont need to prepend users on unambiguous column
* Use json extract instead of shorthand
* Dont count timezone if timezone default length
* CI

* MM-25710: Use an efficient cache serialization algorithm
We investigate 3 packages for selecting a suitable replacement
for gob encoding. The algorithm chosen was msgpack which gives
a decent boost over the standard gob encoding.
Any external schema dependent algorithms like protobuf, flatbuffers, avro,
capn'proto were not considered as that would entail converting the model structs
into separate schema objects and then code generating the Go structs.
It could be done theoretically at a later stage specifically for structs
which are in the hot path. This is a general solution for now.
The packages considered were:
- github.com/tinylib/msgp
- github.com/ugorji/go/codec
- github.com/vmihailenco/msgpack/v5
msgp uses code generation to generate encoding/decoding code without the reflection overhead.
Theoretically, therefore this is supposed to give the fastest performance. However, a major
flaw in that package is that it works only at a file/directory level, not at a package level.
Therefore, for structs which are spread across multiple files, it becomes near to impossible
to chase down all transitive dependencies to generate the code. Even if that's done, it fails
on some complex type like xml.Name and time.Time. (See: https://github.com/tinylib/msgp/issues/274#issuecomment-643654611)
Therefore, we are left with 2 choices. Both of them use the same underlying algorithm.
But msgpack/v5 wraps the encoders/decoders in a sync.Pool. To make a perfect apples-apples
comparison, I wrote a sync.Pool for ugorji/go/codec too and compared performance.
msgpack/v5 came out to be the fastest by a small margin.

In general, we can see that the time to marshal/unmarshal pays off as the size of the struct
increases.
We can see that msgpack/v5 is faster for CPU but very slightly heavier on memory.
Since we are interested in fastest speed, we choose msgpack/v5.
As a future optimization, we can use a mix of msgpack and msgp for hot structs.
To do that, we would need to shuffle around some code so that for the hot struct,
all its dependencies are in the same file.
Let's use this in production for some time, watch grafana graphs for the hottest caches
and come back to optimizing this more once we have more data.
Side note: we have to do with micro-benchmarks for the time being, because all the caches
aren't migrated to cache2 interface yet. Once that's in, we can actually run some load tests
and do comparisons.
* Bring back missing import
* Fix tests
* new job type created that checks for expired mobile sessions and pushes notifications.
* only send session expired notifications if ExtendSessionLengthWithActivity is enabled.
* includes schema change: field added to Sessions table
* Improve CreatePostCheckOnlineStatus
We improve the flakyness of the test by making the websocket
status checks synchronous after making each request.
This makes the status responses more reliable because in very
busy CI environments the goroutine scheduler can indeed send
the response which is made by a later HTTP request before the first one.
* Update api4/post_test.go
