## Problem
The first version of the ingest benchmark had some parsing and reporting
logic in shell script inside GitHub workflow.
it is better to move that logic into a python testcase so that we can
also run it locally.
## Summary of changes
- Create new python testcase
- invoke pgcopydb inside python test case
- move the following logic into python testcase
- determine backpressure
- invoke pgcopydb and report its progress
- parse pgcopydb log and extract metrics
- insert metrics into perf test database
- add additional column to perf test database that can receive endpoint
ID used for pgcopydb run to have it available in grafana dashboard when
retrieving other metrics for an endpoint
## Example run
https://github.com/neondatabase/neon/actions/runs/11860622170/job/33056264386
## Problem
We call `check-build-tools-image` twice for each workflow whenever we
use it, along with `build-build-tools-image`, once as a workflow itself,
and the second time from `build-build-tools-image`. This is not
necessary.
## Summary of changes
- Inline `check-build-tools-image` into `build-build-tools-image`
- Remove separate `check-build-tools-image` workflow
We found that exporting GH Workflow Runs in batch is more efficient due
to
- better utilisation of Github API
- and gh runners usage is rounded to minutes, so even when ad-hoc export
is done in 5-10 seconds, we billed for one minute usage
So now we introduce batch exporting, with version v0.2.x of github
workflow stats exporter.
How it's expected to work now:
- every 15 minutes we query for the workflow runs, created in last 2
hours
- to avoid missing workflows that ran for more than 2 hours, every night
(00:25) we will query workflows created in past 24 hours and export them
as well
- should we have query for even longer periods?
- lets see how it works with current schedule
- for longer periods like for days or weeks, it may require to adjust
logic and concurrency of querying data, so lets for now use simpler
version
## Problem
We have no specific benchmark testing project migration of postgresql
project with existing data into Neon.
Typical steps of such a project migration are
- schema creation in the neon project
- initial COPY of relations
- creation of indexes and constraints
- vacuum analyze
## Summary of changes
Add a periodic benchmark running 9 AM UTC every day.
In each run:
- copy a 200 GiB project that has realistic schema, data, tables,
indexes and constraints from another project into
- a new Neon project (7 CU fixed)
- an existing tenant, (but new branch and new database) that already has
4 TiB of data
- use pgcopydb tool to automate all steps and parallelize COPY and index
creation
- parse pgcopydb output and report performance metrics in Neon
performance test database
## Logs
This benchmark has been tested first manually and then as part of
benchmarking.yml workflow, example run see
https://github.com/neondatabase/neon/actions/runs/11757679870
## Problem
Once we enable the merge queue for the `main` branch, it won't be
possible to adjust the commit message right after pressing the "Squash
and merge" button and the PR title + description will be used as is.
To avoid extra noise in the commits in the `main` with the checklist
leftovers, I propose removing the checklist from the PR template and
keeping only the Problem / Summary of changes.
## Summary of changes
- Remove the checklist from the PR template
## Problem
GitHub API can return error 500, and it fails jobs that use
`actions/github-script` action.
## Summary of changes
- Add `retry: 500` to all `actions/github-script` usage
## Problem
The Merge queue doesn't work because it expects certain jobs, which we
don't have in the `pre-merge-checks` workflow.
But it turns out we can just create jobs/checks with the same names in
any workflow that we run.
## Summary of changes
- Add `conclusion` jobs
- Create `neon-cloud-e2e` status check
- Add a bunch of `if`s to handle cases with no relevant changes found
and prepare the workflow to run rust checks in the future
- List the workflow in `report-workflow-stats` to collect stats about it
## Problem
To prevent breaking main after Python 3.11 PR get merged
we need to enable merge queue and run `check-codestyle-python`
job on it
## Summary of changes
- Move `check-codestyle-python` to a reusable workflow
- Run this workflow on `merge_group` event
set-docker-config-dir was replicated over multiple repositories.
The replica of this action was removed from this repository and it's
using the version from github.com/neondatabase/dev-actions instead
## Problem
The IAM role associated with our github action runner supports a max
token expiration which is lower than the value we tried.
## Summary of changes
Since we believe to have understood the performance regression we (by
ensuring availability zone affinity of compute and pageserver) the job
should again run in lower than 5 hours and we revert this change instead
of increasing the max session token expiration in the IAM role which
would reduce our security.
## Problem
clickbench regression causes clickbench to run >9 hours and the AWS
session token is expired before the run completes
## Summary of changes
extend lifetime of session token for this job to 12 hours
## Problem
click bench job in benchmarking workflow has a performance regression
causing it to run in timeout of max job run.
Suspected root cause:
Project has been migrated from single pageserver to storage controller
managed project on Oct 14th.
Since then the regression shows.
## Summary of changes
Increase timeout of pytest to 12 hours.
Increase job timeout to 12 hours
## Problem
Based on a recent proxy deployment issue, we deployed another proxy
version (proxy-scram), which was not needed when deploying a specific
proxy type. we have
[PR](https://github.com/neondatabase/infra/pull/2142) to update on the
infra branch and need to update CI in this repo which triggers proxy
deployment.
## Summary of changes
- Update proxy deployment flag

## Problem
We have `git config --global --add safe.directory ...` leftovers from the
past, but `actions/checkout` does it by default (since v3.0.2, we use v4)
## Summary of changes
- Remove `git config --global --add safe.directory ...` hack
## Problem

## Summary of changes
- Use `build-tools:pinned-bookworm` whenever we download Neon artefact
## Problem
Our dockerfiles, for some historical reason, have unconventional names
`Dockerfile.<something>`, and some tools (like GitHub UI) fail to highlight
the syntax in them.
> Some projects may need distinct Dockerfiles for specific purposes. A
common convention is to name these `<something>.Dockerfile`
From: https://docs.docker.com/build/concepts/dockerfile/#filename
## Summary of changes
- Rename `Dockerfile.build-tools` -> `build-tools.Dockerfile`
- Rename `compute/Dockerfile.compute-node` ->
`compute/compute-node.Dockerfile`
This should make it a little bit easier for people wanting to check if
their files are formated correctly. Has the added bonus of making the CI
check simpler as well.

There are quite a few benefits to this approach:
- Reduce config duplication
- The two sql_exporter configs were super similar with just a few
differences
- Pull SQL queries into standalone files
- That means we could run a SQL formatter on the file in the future
- It also means access to syntax highlighting
- In the future, run different queries for different PG versions
- This is relevant because right now, we have queries that are failing
on PG 17 due to catalog updates

## Problem
This PR switches CI and Storage to Debain 12 (Bookworm) based images.
## Summary of changes
- Add Debian codename (`bookworm`/`bullseye`) to most of docker tags,
create un-codenamed images to be used by default
- `vm-compute-node-image`: create a separate spec for `bookworm` (we
don't need to build cgroups in the future)
- `neon-image`: Switch to `bookworm`-based `build-tools` image
- Storage components and Proxy use it
- CI: run lints and tests on `bookworm`-based `build-tools` image
## Problem
When `Dockerfile.build-tools` gets changed, several PRs catch up with
it and some might get unexpectedly cancelled workflows because of
GitHub's concurrency model for workflows.
See the comment in the code for more details.
It should be possible to revert it after
https://github.com/orgs/community/discussions/41518 (I don't expect it
anytime soon, but I subscribed)
## Summary of changes
- Do not queue `build-build-tools-image` workflows in the concurrency
group
## Problem
Action `run-python-test-set` fails if it is not used for `regress_tests`
on release PR, because it expects
`test_compatibility.py::test_create_snapshot` to generate a snapshot,
and the test exists only in `regress_tests` suite.
For example, in https://github.com/neondatabase/neon/pull/9291
[`test-postgres-client-libs`](https://github.com/neondatabase/neon/actions/runs/11209615321/job/31155111544)
job failed.
## Summary of changes
- Add `skip-if-does-not-exist` input to `.github/actions/upload` action
(the same way we do for `.github/actions/download`)
- Set `skip-if-does-not-exist=true` for "Upload compatibility snapshot"
step in `run-python-test-set` action
This job takes an extraordinary amount of time for what I understand it
to do. The obvious win is caching dependencies.
Rory disabled caching in cd5732d9d8.
I assume this was to get gen3 runners up and running.

## Problem
We are seeing frequent pageserver startup timelines while it calls
syncfs(). There is an existing fixture that syncs _after_ tests, but not
before the first one. We hypothesize that some failures are happening on
the first test in a job.
## Summary of changes
- extend the existing sync_after_each_test to be a sync between all
tests, including sync'ing before running the first test. That should
remove any ambiguity about whether the sync is happening on the correct
node.
This is an alternative to https://github.com/neondatabase/neon/pull/8957
-- I didn't realize until I saw Alexander's comment on that PR that we
have an existing hook that syncs filesystems and can be extended.
## Problem
`pgbench-pgvector` job from Nightly Benchmarks fails with the error:
```
/__w/_temp/f45bc2eb-4c4c-4f0a-8030-99079303fa65.sh: line 17: LD_LIBRARY_PATH: unbound variable
```
## Summary of changes
- Fix `LD_LIBRARY_PATH: unbound variable` error in benchmarks
## Problem
Nightly Benchmarks have been broken for some time due to various
reasons, this PR fixes it
## Summary of changes
- Pull `build-tools` image from dockerhub for `benchmarking` workflow
- Use `aws-actions/configure-aws-credentials` to upload/download
artifacts from S3
- Fix Postgres 16 installation (for pgbench)
Part of #8130
## Problem
After deploying https://github.com/neondatabase/infra/pull/1927, we
shipped `io_buffer_alignment=512` to all prod region. The
`AdjacentVectoredReadBuilder` code path is no longer taken and we are
running pageserver unit tests 6 times in the CI. Removing it would
reduce the test duration by 30-60s.
## Summary of changes
- Remove `AdjacentVectoredReadBuilder` code.
- Bump the minimum `io_buffer_alignment` requirement to at least 512
bytes.
- Use default `io_buffer_alignment` for Rust unit tests.

## Problem
The latest storage release has generated artifacts for Postgres 17,
so we can enable compatibility tests this version
## Summary of changes
- Unskip `test_backward_compatibility` / `test_forward_compatibility` on
Postgres 17
A cherry-pick from the previous release (#9131)
## Problem
Login to prod ECR doesn't work anymore:
```
Retrieving registries data through *** SDK...
*** ECR detected with eu-central-1 region
Error: The security token included in the request is invalid.
```
## Summary of changes
- Fix login to prod ECR by using `aws-actions/configure-aws-credentials`
The pg_install/build directory contains .o files and such intermediate
results from the build, which are not needed in the final tarball.
Except for src/test/regress/regress.so and a few other .so files in that
directory; keep those.
This reduces the size of the neon-Linux-X64-release-artifact.tar.zst
artifact from about 1.5 GB to 700 MB.
(I attempted this a long time ago already, by moving the build/
directory out of pg_install altogether, see PR #2127. But I never got
around to finish that work.)

## Problem
All the other patches were moved to the compute directory, and only one
was left in the patches subdirectory in the root directory.
## Summary of changes
The patch was moved to the compute directory as others
## Problem
We need to be able to run the regression tests against a cloud-based
Neon staging instance to prepare the migration to the arm architecture.
## Summary of changes
Some tests were modified to work on the cloud instance (i.e. added
passwords, server-side copy changed to client-side, etc)

Seems nice to keep all these together. This also provides a nice place
for a README file to describe the compute image build process. For
now, it briefly describes the contents of the directory, but can be
expanded.
We can't FlushOneBuffer when we're in redo-only mode on PageServer, so
make execution of that function conditional on us not running in
pageserver walredo mode.
We frequently mess up our submodule references. This adds one safeguard:
it checks that the submodule references are only updated "forwards", not
to some older commit, or a commit that's not a descended of the previous
one.
As next step, I'm thinking that we should automate things so that when
you merge a PR to the 'neon' repository that updates the submodule
references, the REL_*_STABLE_neon branches are automatically updated to
match the submodule references. That way, you never need to manually
merge PRs in the postgres repository, it's all triggered from commits in
the 'neon' repository. But that's not included here.
It's pretty expensive to run, and there is very little difference
between debug and release builds that could lead to different clippy
warnings.
This is extracted from PR #8912. That PR wandered off into various
improvements we could make, but we seem to have consensus on this part
at least.
## Problem
It turns out the previous approach (with `skip_if` input) doesn't work
(from https://github.com/neondatabase/neon/pull/9017).
Revert it and use more straightforward if-conditions
## Summary of changes
- Revert efbe8db7f1
- Add if-condition to`promote-compatibility-data` job and relevant
comments
## Problem
We do use `actions/checkout` with `fetch-depth: 0` when it's not
required
## Summary of changes
- Remove unneeded `fetch-depth: 0`
- Add a comment if `fetch-depth: 0` is required
## Problem
We've got 2 non-blocking failures on the release pipeline:
- `promote-compatibility-data` job got skipped _presumably_ because one
of the dependencies of `deploy` job (`push-to-acr-dev`) got skipped
(https://github.com/neondatabase/neon/pull/8940)
- `coverage-report` job fails because we don't build debug artifacts in
the release branch (https://github.com/neondatabase/neon/pull/8561)
## Summary of changes
- Always run `push-to-acr-dev` / `push-to-acr-prod` jobs, but add
`skip_if` parameter to the reusable workflow, which can skip the job
internally, without skipping externally
- Do not run `coverage-report` on release branches
## Problem
`gather-rust-build-stats` extra CI job fails with
```
"PQ_LIB_DIR" doesn't exist in the configured path: "/__w/neon/neon/pg_install/v16/lib"
```
## Summary of changes
- Use the path to Postgres 17 for the `gather-rust-build-stats` job.
The job uses Postgres built by `make walproposer-lib`
This adds preliminary PG17 support to Neon, based on RC1 / 2024-09-04

NOTICE: The data produced by the included version of the PostgreSQL fork
may not be compatible with the future full release of PostgreSQL 17 due to
expected or unexpected future changes in magic numbers and internals.
