* ci: shard server Postgres tests into 4 parallel runners (#35739)
* ci: add test sharding plumbing to server CI
Add infrastructure for upcoming test sharding without changing behavior:
- Add shard-index and shard-total inputs to server-test-template.yml
(defaults preserve existing single-runner behavior)
- Add timing cache restore step (activates only when shard-total > 1)
- Add merge-postgres-test-results job to server-ci.yml that:
- Merges JUnit XML reports from shard artifacts
- Saves timing data cache for future shard balancing
- Handles both single-artifact and multi-shard scenarios
- Add .gitignore entries for timing cache and shard work files

* ci: shard server Postgres tests into 4 parallel runners
Extract sharding logic into standalone, tested scripts and enable
4-shard parallel test execution for server Postgres CI:
Scripts:
- server/scripts/shard-split.js: Node.js bin-packing solver that
assigns test packages to shards using timing data from previous runs.
Two-tier strategy: light packages (<2min) whole, heavy packages
(api4, app) split at individual test level.
- server/scripts/run-shard-tests.sh: Multi-run wrapper that calls
gotestsum directly for each package group with -run regex filters.
- server/scripts/shard-split.test.js: 8 test cases covering round-robin
fallback, timing-based balancing, heavy package splitting, JUnit XML
fallback, and enterprise package separation.
Workflow changes:
- server-test-template.yml: Add shard splitting step that discovers test
packages and runs the solver. Modified Run Tests step to use wrapper
script when sharding is active.
- server-ci.yml: Add 4-shard matrix to test-postgres-normal. Update
merge job artifact patterns for shard-specific names.
Performance: 7.2 min with timing cache vs 62.5 min baseline = 88%
wall-time improvement. First run without cache uses JUnit XML fallback
or round-robin, then populates the cache for subsequent runs.

* fix: raise heavy package threshold to 5 min to preserve test isolation
sqlstore integrity tests scan the entire database and fail when other
packages' test data is present. At 182s, sqlstore was just over the
120s threshold and getting split at test level. Raising to 300s keeps
only api4 (~38 min) and app (~15 min) as heavy — where the real
sharding gains are — while sqlstore, elasticsearch, etc. stay whole
and maintain their test isolation guarantees.

* ci: only save test timing cache on default branch
PR branches always restore from master's timing cache via restore-keys
prefix matching. Timing data is stable day-to-day so this eliminates
cache misses on first PR runs and reduces cache storage.

* ci: skip FIPS tests on PRs (enterprise CI handles compile check)
Per review feedback: the enterprise CI already runs a FIPS compile
check on every PR. Running the full FIPS test suite on PRs is redundant
since it uses the identical test suite as non-FIPS — the only
FIPS-specific failure mode is a build failure from non-approved crypto
imports, which the enterprise compile check catches.
Full FIPS tests continue to run on every push to master.

* fix: address review feedback on run-shard-tests.sh
- Remove set -e so all test runs execute even if earlier ones fail;
track failures and exit with error at the end (wiggin77)
- Remove unused top-level COVERAGE_FLAG variable (wiggin77)
- Fix RUN_IDX increment position so report, json, and coverage files
share the same index (wiggin77)
- Update workflow comment: heavy threshold is 5 min, not 2 min (wiggin77)

* fix: avoid interpolating file paths into generated shell script
Read shard package lists from files at runtime instead of interpolating
them into the generated script via printf. This prevents theoretical
shell metacharacter injection from directory names, as flagged by
DryRun Security.

* fix(ci): rename merged artifact to match server-ci-report glob
The merged artifact was named postgres-server-test-logs-merged which
does not match the *-test-logs pattern in server-ci-report.yml,
causing Postgres test results to be missing from PR/commit reports.
Also pins junit-report-merger to exact version 7.0.0 for supply chain
safety.

* fix(ci): pass RACE_MODE env into Docker container
RACE_MODE was set on the host runner but never included in the docker
run --env list. The light-package path worked because the heredoc
expanded on the host, but run-shard-tests.sh reads RACE_MODE at
runtime inside the container where it was unset. This caused heavy
packages (api4, app) to silently lose -race detection.

* fix(ci): discover new tests in heavy packages not in timing cache
Tests not present in the timing cache (newly added or renamed) would
not appear in any shard -run regex, causing them to silently skip.
After building items from the cache, run go test -list to discover
current test names and assign any cache-missing tests to shards via
the normal bin-packing algorithm with a small default duration.

* fix(ci): add missing line continuation backslash in docker run
The previous --env FIPS_ENABLED line was missing a trailing backslash
after adding --env RACE_MODE, causing docker run to see a truncated
command and fail with "requires at least 1 argument".

* fix(ci): add setup-go step for shard test discovery
go test -list in shard-split.js runs on the host runner via execSync,
but Go is only available inside the Docker container. Without this
step, every invocation fails silently and new-test discovery is a
no-op. Adding actions/setup-go before the shard split step ensures
the Go toolchain is available on the host.

go 1.25 does not work with indirect tools 0.11 dependency pulled by
gotestsum.
* Use sync.WaitGroup.Go to simplify goroutine creation
Replace the wg.Add(1) + go func() { defer wg.Done() }() pattern with
wg.Go(), which was introduced in Go 1.25.

* removes temp workflow-dispatch condition

* upgrade golangci-lint (#35845)
* test: clean up channel store data after TestChannelStore (#36066)
TestChannelStore sub-tests create channels, members, and team members
using fake TeamIds and UserIds (model.NewId() for non-existent rows).
These records are left in the database and cause integrity tests
(TestCheck*) running in the same binary to fail their full-table scans.
Register a t.Cleanup on TestChannelStore that purges the affected
tables entirely. A blanket purge is safe: the schema enforces no FK
constraints, and every test suite creates its own data independently.
* Fix command injection in server-test-template workflow (#36080)
Replace the unquoted heredoc (which embedded GITHUB_HEAD_REF into a
generated script) with a cp of the existing run-shard-tests.sh, which
already handles the light-only case. Pass BUILD_NUMBER and TEST_TARGET
as explicit docker env vars instead of interpolating them into script
content.
* fix(ci): restore testname format in sharded gotestsum runs (#36078)
run-shard-tests.sh called gotestsum directly without --format, so it
fell back to gotestsum's default (pkgname) instead of the testname
format set by the Makefile. Pass --format "${GOTESTSUM_FORMAT:-testname}"
to match the Makefile default.

Sometimes a broad distinction of just a channelID or a userID
is not enough to efficiently send a websocket event to users.
In several cases, depending on the user and channel, we might
need to modify the message. Therefore, we introduce the
concept of a channel hook that will get executed if the scope
is set to a channel. This hook can be populated at the app layer
to perform any application specific logic to the event.
Care must be taken to avoid race conditions as the passed event
is not deep copied. It is left to the user to treat it carefully.
For this issue, the main problem was that since we don't know
which users have permissions to which channels, we had to go through
_all_ members of a channel to figure that out. This was redundant
since a large portion of those users might not even be connected
at that time.
We solve this with the channel hook where we push this check
to be performed later while actually sending the event. This
reduces the computation to be done only for _connected_ users
rather than _all_ users of a channel.
The next iteration of this should be to use websocket subscriptions
to monitor exactly which users are on that channel to even
trim down that list. That is a larger initiative to be taken later.
Tested locally with a channel of 50 users. Here are rough results:
```
With PR:
patchPost 97ms
createPost 90ms
Master:
patchPost 306ms
createPost - 298ms
```
https://mattermost.atlassian.net/browse/MM-42810
```release-note
Improve performance while sending messages
with permalinks to channels with large number of users.
```
It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
https://mattermost.atlassian.net/browse/MM-53032
```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public
```
There is a standard IDNA2008 which defines how unicode characters
in domain names can be compared using UTS (Unicode Technical Standard) 46.
We use that to convert any links in messages to ASCII and
then compare with the domain list in config.
