This prevents us from overwriting all blocks of a relation when we
extend the relation without first caching the size - get_cached_relsize
does not guarantee a correct result when it returns `false`.
This fixes all kinds of problems related to missing params,
like broken timestamps (due to `integer_datetimes`).
This solution is not ideal, but it will help. Meanwhile,
I'm going to dedicate some time to improving connection machinery.
Note that this **does not** fix problems with passing certain parameters
in a reverse direction, i.e. **from client to compute**. This is a
separate matter and will be dealt with in an upcoming PR.
this should help us in the future to have more freedom with spawning
tasks and cancelling things, most importantly blocking tasks (assuming
the CancellationToken::is_cancelled is performant enough).
CancellationToken allows creation of hierarchical cancellations, which
would also simplify the task_mgr shutdown operation, rendering it
unnecessary.
Do not run Nightly Benchmarks on `neon-captest-new`.
This is a temporary solution to avoid spikes in the storage we consume
during the test run. To collect data for the default instance, we could
run tests weekly (i.e. not daily).
IMDSv2 has limits, and if we query it on every s3 interaction we are
going to go over those limits. Changes the s3_bucket client
configuration to use:
- ChainCredentialsProvider to handle env variables or imds usage
- LazyCachingCredentialsProvider to actually cache any credentials

I saw an excessive number of index file upload operations in
production, even when nothing on the timeline changes. It was because
our GC schedules index file upload if the GC cutoff LSN is advanced,
even if the GC had nothing else to do. The GC cutoff LSN marches
steadily forwards, even when there is no user activity on the
timeline, when the cutoff is determined by the time-based PITR
interval setting. To dial that down, only schedule index file upload
when GC is about to actually remove something.
Previously, the /v1/tenant/:tenant_id/timeline/:timeline_id/do_gc API
call performed a flush and compaction on the timeline before
GC. Change it not to do that, and change all the tests that used that
API to perform compaction explicitly.
The compaction happens at a slightly different point now. Previously,
the code performed the `refresh_gc_info_internal` step first, and only
then did compaction on all the timelines. I don't think that was what
was originally intended here. Presumably the idea with compaction was
to make some old layer files available for GC. But if we're going to
flush the current in-memory layer to disk, surely you would want to
include the newly-written layer in the compaction too. I guess this
didn't make any difference to the tests in practice, but in any case,
the tests now perform the flush and compaction before any of the GC
steps.
Some of the tests might not need the compaction at all, but I didn't
try hard to determine which ones might need it. I left it out from a
few tests that intentionally tested calling do_gc with an invalid
tenant or timeline ID, though.
- Use only one templated section for most postgres-versioned steps
- Clean up neon_walredo, too, when running neon-pg-ext-clean
- Depend on the various cleanup steps for `clean` instead of manually
executing those cleanup steps.
If we get cancelled before jh.await returns we've take()n the join handle but
drop the result on the floor.
Fix it by setting self.join_handle = None after the .await

We do the accounting exclusively after updating remote IndexPart successfully.
This is cleaner & more robust than doing it upon completion of
individual layer file uploads / deletions since we can uset .set()
insteaf of add()/sub().
NB: Originally, this work was intended to be part of #3013 but it
turns out that it's completely orthogonal.
So, spin it out into this PR for easier review.
Since this change is additive, it won't break anything.
Temporarily disable `test_seqscans` for remote projects; they acquire
too much space and time. We can try to reenable it back after switching
to per-test projects.

Before this patch, when we decide to rename a layer file to backup
because of layer file size mismatch, we would not remove the layer from
the layer map, but remote the on-disk file.
Because we re-download the file immediately after, we simply end up with
two layer objects in memory that reference the same file in the layer
map. So, GetPage() would work fine until one of the layers gets
delete()'d. The other layer's delete() would then fail.
Future work: prevent insertion of the same layer at LayerMap level
so that we notice such bugs sooner.
Replace actions/setup-python@v4 with the ansible image to fix
```

Error: The version '3.10' with architecture 'x64' was not found for this operating system.

Removes the race during pageserver initial timeline creation that lead to partial layer uploads.
This race is only reproducible in test code, we do not create initial timelines in cloud (yet, at least), but still nice to remove the non-deterministic behavior.
This patch aims to fix some of the inconsistencies in error reporting,
for example "Internal error" or "Console request failed" instead of
"password authentication failed for user '<NAME>'".
refactor: use new type LayerFileName when referring to layer file names in PathBuf/RemotePath
Before this patch, we would sometimes carry around plain file names in
`Path` types and/or awkwardly "rebase" paths to have a unified
representation of the layer file name between local and remote.
This patch introduces a new type `LayerFileName` which replaces the use
of `Path` / `PathBuf` / `RemotePath` in the `storage_sync2` APIs.
Instead of holding a string, it contains the parsed representation of
the image and delta file name.
When we need the file name, e.g., to construct a local path or
remote object key, we construct the name ad-hoc.
`LayerFileName` is also serde {Dese,Se}rializable, and in an initial
version of this patch, it was supposed to be used directly inside
`IndexPart`, replacing `RemotePath`.
However,
commit 3122f3282f
Ignore backup files (ones with .n.old suffix) in download_missing
fixed handling of `*.old` backup file names in IndexPart, and we need
to carry that behavior forward.
The solution is to remove `*.old` backup files names during
deserialization. When we re-serialize the IndexPart, the `*.old` file
will be gone.
This leaks the `.old` file in the remote storage, but makes it safe
to clean it up later.
There is additional churn by a preliminary refactoring that got squashed
into this change:
split off LayerMap's needs from trait Layer into super trait
That refactoring renames `Layer` to `PersistentLayer` and splits off a subset
of the functions into a super-trait called `Layer`.
The upser trait implements just the functions needed by `LayerMap`, whereas
`PersisentLayer` adds the context of the pageserver.
The naming is imperfect as some functions that reside in `PersistentLayer`
have nothing persistence-specific to it. But it's a step in the right direction.

https://github.com/neondatabase/neon/pull/2407
* adds `hashFiles('rust-toolchain.toml')` into Rust cache keys, thus
removing one of the manual steps to do when upgrading rustc
* copies Python and Rust style checks from the `codestyle.yml` workflow
* adjusts shell defaults in the main workflow
* replaces `codestyle.yml` with a `neon_extra_builds.yml` worlflow
The new workflow runs on commits to `main` (`codestyle.yml` was run per
PR), and runs two custom builds on GH agents:
* macos-latest, to ensure the entire project compiles on it (no tests
run)
There were no frequent breakages on macOs in our builds, so we can check
it rarely without making every storage PR to wait for it to complete.
The updated mac build use release builds now, so presumably should work
a bit faster due to overall smaller files to cache between builds.
* ubuntu-latest, without caches, to produce full compilation stats for
Rust builds and upload it as an artifact to GitHub
Old `clippy build --timings` stats were collected from the builds that
use caches and incremental calculation hence never could produce a full
report, it got removed.
