Currently it's included with minimal changes and lives aside of the main
workspace. Later we may re-use and combine common parts with zenith
control_plane.
This change is mostly needed to unify cloud deployment pipeline:
1.1. build compute-tools image
1.2. build compute-node image based on the freshly built compute-tools
2. build zenith image
So we can roll new compute image and new storage required by it to
operate properly. Also it becomes easier to test console against some
specific version of compute-node/-tools.
Git commit sha is displayed when --version flag is used and is written
to logs during service startup. Uses git_version crate when git is
available, and GIT_VERSION environment variable otherwise which is the case for docker
builds.
tests are based on self-hosted runner which is physically close
to our staging deployment in aws, currently tests consist of
various configurations of pgbenchi runs.
Also these changes rework benchmark fixture by removing globals and
allowing to collect reports with desired metrics and dump them to json
for further analysis. This is also applicable to usual performance tests
which use local zenith binaries.

This job will be responsible for triggering remote CI pipeline in
zenithdb/console repository. That way, we'll always know when
a PR to zenithdb/zenith breaks the cloud console app.
This provides a pytest fixture to record metrics from pytest tests. The
The recorded metrics are printed out at the end of the tests.
As a starter, this includes on small test, using pgbench. It prints out
three metrics: the initialization time, runtime of 5000 xacts, and the
repository size after the tests.
For a CI build, storing incremental build data just makes the cache
bigger, for minimal gain.
Also, for Rust < 1.52.1 there are incremental compilation bugs. CircleCI
is currently building on 1.51.
This only affects the debug build; incremental compilation isn't used on
the release build.
Add parameters to specify which kind of build; run a debug and release
variant for each job.
Eventually this will be too many jobs, but for now this is a nice start.
Also, bump the cache string to "v02" so we don't mix up our cache output
with other branches.
- The 'pageserver' fixture now sets up the repository and starts up
the Page Server automatically. In other words, the 'pageserver'
fixture provides a Page Server that's up and running and ready to
use in tests.
- The 'pageserver' fixture now also creates a branch called 'empty',
right after initializing the repository. By convention, all the
tests start by createing a new branch off 'empty' for the test. This
allows running all the tests against the same Page Server
concurrently. (I haven't tested that though. pytest doensn't
provide an option to run tests in parallel but there are extensions
for that.)
- Remove the 'zen_simple' fixture. Now that 'pageserver' provides
server that's up and running, it's pretty simple to use the
'pageserver' and 'postgres' fixtures directly.
- Don't assume host name or ports in the tests. They now use the
fields in the fixtures for that. That allows assigning the ports
dynamically, making it possible to run multiple page servers in
parallel, or running the tests in parallel with another page
server. This commit still hard codes the Page Server's port in the
fixture, though, so more work is needed to actually make it
possible.
- I made some changes to the 'postgres' fixture in commit 532918e13d,
which broke the other tests. Fix them.
- Divide the tests into two "batches" of roughly equal runtime, which
can be run in parallel
- Merge the 'test_file' and 'test_filter' options in CircleCI config
into one 'test_selection' option, for simplicity.
