* 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.

* updated go to version 1.25.8 (#35817)
* updated go to version 1.25.8
* updated gotestsum version to work with go 1.25.8
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.
* pushes fips image on workflow dispatch to allow fips test to run on go version update
* fix new requirements for FIPS compliance imposed on updating to go 1.25.8
* updates openssl symbol check for library shipped with FIPS new versions
go-openssl v2 shipped with FIPS versions starting from 1.25 uses mkcgo to generate
bindings causing symbol names to be different.
* removes temp workflow-dispatch condition
* keep versions out of agents md file
* 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.

- We introduce 2 new APIs:
1. Scan: this allows incremental iteration
without blocking the Redis server and is the
recommended way to iterate over keys. With this,
we have entirely removed the need for Keys.
2. RemoveMulti: this allows deletion of multiple
keys in a single operation which optimizes
network round trips.
- While here, we make a small improvement to
GetStatusFromCache, where we remove the shallow
copy which wasn't necessary because we always
serialize the data from the cache.
- We do not use Redis for session cache because of
frequent requests to iterate the entire cache which leads
to a lot of `SCAN` calls.
- Avoid broadcasting status update messages for Redis case.
- Setting cache expiry for status cache
- Removing .Set method altogether to prevent
any chances of setting an item with no expiry.

```release-note
NONE
```
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
```
* Avoid calling the user count query in future if we get a count > 0
