## Problem
There is too much delay between merging a PR into `main` and deploying
the changes to staging
## Summary of changes
- Trigger `deploy` job without waiting for `build-and-test-locally` job
## Problem
The `/__w/neon/neon` directory is mounted from host to container and
persists between runs.
Sometimes the next workflow run fails to delete it:
```
Deleting the contents of '/__w/neon/neon'
Error: File was unable to be removed Error: EACCES: permission denied, rmdir '/__w/neon/neon/allure-2.32.2/bin'
```
## Summary of changes
- Download and install allure to `/tmp` which exists in container only
Ref https://github.com/neondatabase/cloud/issues/27186
## Problem
Benchmarks results are inconsistent on existing small-metal runners
## Summary of changes
Introduce new `unit-perf` runners, and lets run benchmark on them.
The new hardware has slower, but consistent, CPU frequency - if run with
default governor schedutil.
Thus we needed to adjust some testcases' timeouts and add some retry
steps where hard-coded timeouts couldn't be increased without changing
the system under test.

Right now there are only 2 runners of that class, and if we decide to go
with them, we have to check how much that type of runners we need, so
jobs not stuck with waiting for that type of runners available.
However we now decided to run those runners with governor performance
instead of schedutil.
This achieves almost same performance as previous runners but still
achieves consistent results for same commit
Related issue to activate performance governor on these runners

## Verification that it helps

## Problem
We've started sending slack notifications for failed container image
pushes that are being retried. There are more messages coming in than
expected, so clicking through the link to see what image failed is
happening more often than we hoped.
## Summary of changes
- Make slack notifications clearer, including whether the job succeeded
and what retries have happened.
- Log failures/retries in step more clearly, so that you can easily see
when something fails.
## Problem
Changes in compute can cause errors in tests if another version of
`neon-test-extensions` image is used.
## Summary of changes
Use the same version of `neon-test-extensions` image as `compute` one
for docker-compose based extension tests.
## Problem
We had a problem with https://github.com/neondatabase/neon/pull/11413
having e2e tests failing, because an e2e test
(8d271bed47)
depended on an unreleased pageserver fix
(0ee5bfa2fc).
This came up because neon release CI runs against the most recent
releases of the other components, but cloud e2e tests run against
latest, which is tagged from main.
## Summary of changes
Add an additional `released` tag for released versions.
## Alternative to consider
We could (and maybe should) instead switch to `latest` being used for
released versions and `main` being used where we use `latest` right now.
That'd also mean we don't have to adjust the CI in the cloud repo.
## Problem
We've seen quite a few CI failures related to pushes to docker hub
failing with weird error messages that indicate maybe docker hub is just
not reliable.
## Summary of changes
Retry container image pushing up to 10 times, and send a slack message
if we had to retry, regardless of the job succeeding or not.
## Problem
Hotfix releases mean that sometimes changes in release PRs haven't been
tested and linted yet. Disabling tests and lints is therefore not
necessarily safe. In the future we will check whether tests have run on
the same git tree already to speed things up, but for now we need to
turn tests back on fully. This partially reverts:
https://github.com/neondatabase/neon/pull/11272
## Summary of changes
Run checks on `.*-rc-pr` runs.
## Problem
Sometimes the forced extension upgrade test fails (on schedule) due to a
timeout.
## Summary of changes
The timeout is increased to 60 mins.
## Problem
Current version of GitHub Workflow Stats action pull docker images from
DockerHub, that could be an issue with the new pull limits on DockerHub
side.
## Summary of changes
Switch to version `v0.2.2`, with docker images hosted on `ghcr.io`
## Problem
`github.sha` contains a merge commit of `head` and `base` if we're in a
PR. In release PRs, this makes no sense, because we fast-forward the
`base` branch to contain the changes from `head`.
Even though we correctly use `${{ github.event.pull_request.head.sha ||
github.sha }}` to reference the git commit when building artifacts, we
don't use that when checking out code, because we want to test the merge
of head and base usually. In the case of release PRs, we definitely
always want to test on the head sha though, because we're going to
forward that, and it already has the base sha as a parent, so the merge
would end up with the same tree anyway.
As a side effect, not checking out `${{
github.event.pull_request.head.sha || github.sha }}` also caused
https://github.com/neondatabase/neon/actions/runs/13986389780/job/39173256184#step:6:49
to say `release-tag=release-compute-8187`, while
https://github.com/neondatabase/neon/actions/runs/14084613121/job/39445314780#step:6:48
is talking about `build-tag=release-compute-8186`
## Summary of changes
Run a few things on `github.event.pull_request.head.sha`, if we're in a
release PR.
## Problem
Occasionally getting data from GH cache could be slow, with less than
10MB/s and taking 5+ minutes to download cache:
```
Received 20971520 of 2987085791 (0.7%), 9.9 MBs/sec
Received 50331648 of 2987085791 (1.7%), 15.9 MBs/sec
...
Received 1065353216 of 2987085791 (35.7%), 4.8 MBs/sec
Received 1065353216 of 2987085791 (35.7%), 4.7 MBs/sec
...
```
https://github.com/neondatabase/neon/actions/runs/13956437454/job/39068664599#step:7:17
Resulting in getting cache even longer that build time.
## Summary of changes
Switch to the caches, that are closer to the runners, and they provided
stable throughput about 70-80MB/s
## Problem
#11061 changed how artifacts for releases are built, by
reusing/retagging the artifacts from release PRs. This resulted in the
BUILD_TAG that's baked into the images to not be as expected.
Context: https://neondb.slack.com/archives/C08JBTT3R1Q/p1742333300129069
## Summary of changes
Set BUILD_TAG to the release tag of the upcoming release when running
inside release PRs.
## Problem
https://github.com/neondatabase/neon/pull/11210 migrated pushing images
to ghcr. Unfortunately, it was incomplete in using images from ghcr,
which resulted in a few places referencing the ghcr build-tools image,
while trying to use docker hub credentials.
## Summary of changes
Use build-tools image from ghcr consistently.
## Problem
The pipelines after release merges are slower than they need to be at
the moment. This is because some kinds of tests/checks run on all kinds
of pipelines, even though they only matter in some of those.
## Summary of changes
Run `check-codestyle-{rust,python,jsonnet}`, `build-and-test-locally`
and `trigger-e2e-tests` only on regular PRs, not release PR or pushes to
main or release branches.
## Problem
Docker Hub has new rate limits coming up, and to avoid problems coming
with those we're switching to GHCR.
## Summary of changes
- Push images to GHCR initially and distribute them from there
- Use images from GHCR in docker-compose
## Problem
https://github.com/neondatabase/neon/actions/runs/13894288475/job/38871819190
shows the "Add fast-fordward label to PR to trigger fast-forward merge"
job being skipped. This is due to not using the right variable for
checking which branch the merge queue is merging into.
## Summary of changes
Use the `branch` output of the `meta` task for checking the target
branch of a merge group.
