Service targeted for storing and retrieving LFC prewarm data.
Can be used for proxying S3 access for Postgres extensions like
pg_mooncake as well.
Requests must include a Bearer JWT token.
Token is validated using a pemfile (should be passed in infra/).
Note: app is not tolerant to extra trailing slashes, see app.rs
`delete_prefix` test for comments.
Resolves: https://github.com/neondatabase/cloud/issues/26342
Unrelated changes: gate a `rename_noreplace` feature and disable it in
`remote_storage` so as `object_storage` can be built with musl
## Problem
`TYPE_CHECKING` is used inconsistently across Python tests.
## Summary of changes
- Update `ruff`: 0.7.0 -> 0.11.2
- Enable TC (flake8-type-checking):
https://docs.astral.sh/ruff/rules/#flake8-type-checking-tc
- (auto)fix all new issues
## Problem
Running `pytest.skip(...)` in a test body instead of marking the test
with `@pytest.mark.skipif(...)` makes all fixtures to be initialised,
which is not necessary if the test is going to be skipped anyway.
Also, some tests are unnecessarily skipped (e.g. `test_layer_bloating`
on Postgres 17, or `test_idle_reconnections` at all) or run (e.g.
`test_parse_project_git_version_output_positive` more than on once
configuration) according to comments.
## Summary of changes
- Move `skip_on_postgres` / `xfail_on_postgres` /
`run_only_on_default_postgres` decorators to `fixture.utils`
- Add new `skip_in_debug_build` and `skip_on_ci` decorators
- Replace `pytest.skip(...)` calls with decorators where possible
## Problem
This test restarts services in an undefined order (whatever neon_local
does), which means we should be tolerant of warnings that come from
restarting the storage controller while a pageserver is running.
We can see failures with warnings from dropped requests, e.g.
https://neon-github-public-dev.s3.amazonaws.com/reports/pr-9307/11229000712/index.html#/testresult/d33d5cb206331e28
```
WARN request{method=GET path=/v1/location_config request_id=b7dbda15-6efb-4610-8b19-a3772b65455f}: request was dropped before completing\n')
```
## Summary of changes
- allow-list the `request was dropped before completing` message on
pageservers before restarting services
In the passing, rename it to NeonLocalCli, to reflect that the binary
is called 'neon_local'.
Add wrapper for the 'timeline_import' command, eliminating the last
raw call to the raw_cli() function from tests, except for a few in
test_neon_cli.py which are about testing the 'neon_local' iteself. All
the other calls are now made through the strongly-typed wrapper
functions
Add wrappers for a few commands that didn't have them before. Move the
logic to generate tenant and timeline IDs from NeonCli to the callers,
so that NeonCli is more purely just a type-safe wrapper around
'neon_local'.
There's currently no way to just start/stop broker from `neon_local`.
This PR
* adds a sub-command
* uses that sub-command from the test suite instead of the pre-existing
Python `subprocess` based approach.
Found this useful during investigation
https://github.com/neondatabase/cloud/issues/16886.
Not a user-facing change, but can break any existing `.neon` directories
created by neon_local, as the name of the database used by the storage
controller changes.
This PR changes all the locations apart from the path of
`control_plane/attachment_service` (waiting for an opportune moment to
do that one, because it's the most conflict-ish wrt ongoing PRs like
#6676 )
## Problem
Some existing tests are written in a way that's incompatible with tenant
generations.
## Summary of changes
Update all the tests that need updating: this is things like calling
through the NeonPageserver.tenant_attach helper to get a generation
number, instead of calling directly into the pageserver API. There are
various more subtle cases.
## Problem
Follows on from #5299
- We didn't have a generic way to protect a tenant undergoing changes:
`Tenant` had states, but for our arbitrary transitions between
secondary/attached, we need a general way to say "reserve this tenant
ID, and don't allow any other ops on it, but don't try and report it as
being in any particular state".
- The TenantsMap structure was behind an async RwLock, but it was never
correct to hold it across await points: that would block any other
changes for all tenants.
## Summary of changes
- Add the `TenantSlot::InProgress` value. This means:
- Incoming administrative operations on the tenant should retry later
- Anything trying to read the live state of the tenant (e.g. a page
service reader) should retry later or block.
- Store TenantsMap in `std::sync::RwLock`
- Provide an extended `get_active_tenant_with_timeout` for page_service
to use, which will wait on InProgress slots as well as non-active
tenants.
Closes: https://github.com/neondatabase/neon/issues/5378

## Problem
Currently our testing environment only supports running a single
pageserver at a time. This is insufficient for testing failover and
migrations.
- Dependency of writing tests for #5207
## Summary of changes
- `neon_local` and `neon_fixture` now handle multiple pageservers
- This is a breaking change to the `.neon/config` format: any local
environments will need recreating
- Existing tests continue to work unchanged:
- The default number of pageservers is 1
- `NeonEnv.pageserver` is now a helper property that retrieves the first
pageserver if there is only one, else throws.
- Pageserver data directories are now at `.neon/pageserver_{n}` where n
is 1,2,3...
- Compatibility tests get some special casing to migrate neon_local
configs: these are not meant to be backward/forward compatible, but they
were treated that way by the test.
## Problem
Binaries created from PRs (both in docker images and for tests) have
wrong git-env versions, they point to phantom merge commits.
## Summary of changes
- Prefer GIT_VERSION env variable even if git information was accessible
- Use `${{ github.event.pull_request.head.sha || github.sha }}` instead
of `${{ github.sha }}` for `GIT_VERSION` in workflows
So the builds will still happen from this phantom commit, but we will
report the PR commit.

For better ergonomics. I always found it weird that we used UUID to
actually mean a tenant or timeline ID. It worked because it happened
to have the same length, 16 bytes, but it was hacky.
Merge batch_others and batch_pg_regress. The original idea was to
split all the python tests into multiple "batches" and run each batch
in parallel as a separate CI job. However, the batch_pg_regress batch
was pretty short compared to all the tests in batch_others. We could
split batch_others into multiple batches, but it actually seems better
to just treat them as one big pool of tests and use pytest's handle
the parallelism on its own. If we need to split them across multiple
nodes in the future, we could use pytest-shard or something else,
instead of managing the batches ourselves.
Merge test_neon_regress.py, test_pg_regress.py and test_isolation.py
into one file, test_pg_regress.py. Seems more clear to group all
pg_regress-based tests into one file, now that they would all be in
the same directory.
