* 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.
Increase table size four times to fix the following error:

From what I could understand from the PR, we did not wait enough before
the attach failed.
Extended the wait period a bit and put a check for a status instead of
plain `sleep` to fail if we don't get the expected status.
This is rather a hack to resolve immediate issue:

Properly cleaning this file from index part requires changes to
initialization of remote queue. Because we need to clean it up earlier
than we start warking around files.
With on-demand there will be no walk around layer files becase
download_missing is no longer needed, so I believe it will be
natural to unify this with load_layer_map
Several fixes are included, with among others:
- Prefetching for index bulkdelete calls (e.g. during vacuum), plus v14 compiler warning fix
- A fix for setting LSN on heap pages while setting vm bits
- Some style updates that were lost in the previous wave (v15 only)
Migrate Nightly Benchmarks from captest to staging.
- Migrate GitHub Workflows
- Replace `zenith-benchmarker` with regular runners
- Remove `environment` parameter from Neon GitHub Actions, add
`postgres_version`
- The only job left on captest is `neon-captest-reuse`, which will be
moved to staging after its project migration.

Changes:
* Remove `RemoteObjectId` concept from remote_storage.
Operate directly on /-separated names instead.
These names are now represented by struct `RemotePath` which was renamed from struct `RelativePath`
* Require remote storage to operate on relative paths for its contents, thus simplifying the way to derive them in pageserver and safekeeper
* Make `IndexPart` to use `String` instead of `RelativePath` for its entries, since those are just the layer names
This patch centralize the logic of creating & reading pid files into the
new pid_file module and improves upon / makes explicit a few race conditions
that existed with the previous code.
Starting Processes / Creating Pidfiles
======================================
Before this patch, we had three places that had very similar-looking
match lock_file::create_lock_file { ... }
blocks.
After this change, they can use a straight-forward call provided
by the pid_file:
pid_file::claim_pid_file_for_pid()
Stopping Processes / Reading Pidfiles
=====================================
The new pid_file module provides a function to read a pidfile,
called read_pidfile(), that returns a
pub enum PidFileRead {
NotExist,
NotHeldByAnyProcess(PidFileGuard),
LockedByOtherProcess(Pid),
}
If we get back NotExist, there is nothing to kill.
If we get back NotHeldByAnyProcess, the pid file is stale and we must
ignore its contents.
If it's LockedByOtherProcess, it's either another pidfile reader
or, more likely, the daemon that is still running.
In this case, we can read the pid in the pidfile and kill it.
There's still a small window where this is racy, but it's not a
regression compared to what we have before.
The NotHeldByAnyProcess is an improvement over what we had before
this patch. Before, we would blindly read the pidfile contents
and kill, even if no other process held the flock.
If the pidfile was stale (NotHeldByAnyProcess), then that kill
would either result in ESRCH or hit some other unrelated process
on the system. This patch avoids the latter cacse by grabbing
an exclusive flock before reading the pidfile, and returning the
flock to the caller in the form of a guard object, to avoid
concurrent reads / kills.
It's hopefully irrelevant in practice, but it's a little robustness
that we get for free here.
Maintain flock on Pidfile of ETCD / any InitialPidFile::Create()
================================================================
Pageserver and safekeeper create their pidfiles themselves.
But for etcd, neon_local creates the pidfile (InitialPidFile::Create()).
Before this change, we would unlock the etcd pidfile as soon as
`neon_local start` exits, simply because no-one else kept the FD open.
During `neon_local stop`, that results in a stale pid file,
aka, NotHeldByAnyProcess, and it would henceforth not trust that
the PID stored in the file is still valid.
With this patch, we make the etcd process inherit the pidfile FD,
thereby keeping the flock held until it exits.
* We were missing one cluster in production:
`prod-ap-southeast-1-epsilon` configs.
* We had `metrics` enabled. This means creating `ServiceScrape` objects,
but since those clusters don't have `kube-prometheus-stack` like older
ones, we are missing the CRDs, so the helm deploy fails.
The new "trace_read_requests" option was missing from the
parse_toml_tenant_conf function that reads the config file. Because of
that, the option was ignored, which caused the test_read_trace.py test
to fail. It used to work before commit 9a6c0be823, because the
TenantConfigOpt struct was constructed directly in tenant_create_handler,
but now it is saved and read back from disk even for a newly created
tenant.
The abovementioned bug was fixed in commit 09393279c6 already, which
added the missing code to parse_toml_tenant_conf() to parse the
new "trace_read_requests" option. This commit fixes one more function
that was missed earlier, and adds more detail to the error message if
parsing the config file fails.
helm values for the new `storage-broker`. gRPC, over secure connection
with a proper certificate, but no authentication.
Uses alb ingress in the old cluster and nginx ingress for the new one.
The chart is deployed and the addresses are functional, while the
pipeline doesn't exist yet.
It used to be a separate piece of state, but after 9a6c0be823 it's just
an alias for the Tenant being in Attaching state. It was only used in
one assertion in a test, but that check doesn't make sense anymore, so
just remove it.
Fixes https://github.com/neondatabase/neon/issues/2930
Added basic instrumentation to integrate sentry with the proxy, pageserver, and safekeeper processes.
Currently in sentry there are three projects, one for each process. Sentry url is sent to all three processes separately via cli args.
Closes https://github.com/neondatabase/neon/issues/2537
Follow-up of https://github.com/neondatabase/neon/pull/2950
With the new model that prevents attaching without the remote storage,
it has started to be even more odd to add attach-with-files
functionality (in addition to the issues raised previously).
Adds two separate commands:
* `POST {tenant_id}/ignore` that places a mark file to skip such tenant
on every start and removes it from memory
* `POST {tenant_id}/schedule_load` that tries to load a tenant from
local FS similar to what pageserver does now on startup, but without
directory removals
Move missing_layers property to Option<HashSet<RelativePath>>
This will allow the safe removal of it once the upgrade of all page servers is done with this new code
- Replace `seqscan_prefetch_buffers` with `effective_io_concurrency` and
`maintenance_io_concurrency` for `clickbench-compare` job (see
https://github.com/neondatabase/neon/pull/2876)
- Get the database name in a runtime (it can be `main` or `neondb` or
something else)

- **Enable `enable_seqscan_prefetch` by default**
- Drop use of `seqscan_prefetch_buffers` in favor of
`[maintenance,effective]_io_concurrency`
This includes adding some fields to the HeapScan execution node, and
vacuum state.
- Cleanup some conditionals in vacuumlazy.c
- Clarify enable_seqscan_prefetch GUC description
- Fix issues in heap SeqScan prefetching where synchronize_seqscan
machinery wasn't handled properly.
