## Problem
As described in #7952, the controller's attempt to reconcile a tenant
before finally deleting it can get hung up waiting for the compute
notification hook to accept updates.
The fact that we try and reconcile a tenant at all during deletion is
part of a more general design issue (#5080), where deletion was
implemented as an operation on attached tenant, requiring the tenant to
be attached in order to delete it, which is not in principle necessary.
Closes: #7952
## Summary of changes
- In the pageserver deletion API, only do the traditional deletion path
if the tenant is attached. If it's secondary, then tear down the
secondary location, and then do a remote delete. If it's not attached at
all, just do the remote delete.
- In the storage controller, instead of ensuring a tenant is attached
before deletion, do a best-effort detach of the tenant, and then call
into some arbitrary pageserver to issue a deletion of remote content.
The pageserver retains its existing delete behavior when invoked on
attached locations. We can remove this later when all users of the API
are updated to either do a detach-before-delete. This will enable
removing the "weird" code paths during startup that sometimes load a
tenant and then immediately delete it, and removing the deletion markers
on tenants.
## Problem
Currently we serialize the `TimelineMetadata` into bytes to put it into
`index_part.json`. This `Vec<u8>` (hopefully `[u8; 512]`) representation
was chosen because of problems serializing TimelineId and Lsn between
different serializers (bincode, json). After #5335, the serialization of
those types became serialization format aware or format agnostic.
We've removed the pageserver local `metadata` file writing in #6769.
## Summary of changes
Allow switching from the current serialization format to plain JSON for
the legacy TimelineMetadata format in the future by adding a competitive
serialization method to the current one
(`crate::tenant::metadata::modern_serde`), which accepts both old bytes
and new plain JSON.
The benefits of this are that dumping the index_part.json with pretty
printing no longer produces more than 500 lines of output, but after
enabling it produces lines only proportional to the layer count, like:
```json
{
"version": ???,
"layer_metadata": { ... },
"disk_consistent_lsn": "0/15FD5D8",
"legacy_metadata": {
"disk_consistent_lsn": "0/15FD5D8",
"prev_record_lsn": "0/15FD5A0",
"ancestor_timeline": null,
"ancestor_lsn": "0/0",
"latest_gc_cutoff_lsn": "0/149FD18",
"initdb_lsn": "0/149FD18",
"pg_version": 15
}
}
```
In the future, I propose we completely stop using this legacy metadata
type and wasting time trying to come up with another version numbering
scheme in addition to the informative-only one already found in
`index_part.json`, and go ahead with storing metadata or feature flags
on the `index_part.json` itself.
#7699 is the "one release after" changes which starts to produce
metadata in the index_part.json as json.
fixes https://github.com/neondatabase/neon/issues/7790 (duplicating most
of the issue description here for posterity)
# Background
From the time before always-authoritative `index_part.json`, we had to
handle duplicate layers. See the RFC for an illustration of how
duplicate layers could happen:
a8e6d259cb/docs/rfcs/027-crash-consistent-layer-map-through-index-part.md (L41-L50)
As of #5198 , we should not be exposed to that problem anymore.
# Problem 1
We still have
1. [code in
Pageserver](82960b2175/pageserver/src/tenant/timeline.rs (L4502-L4521))
than handles duplicate layers
2. [tests in the test
suite](d9dcbffac3/test_runner/regress/test_duplicate_layers.py (L15))
that demonstrates the problem using a failpoint
However, the test in the test suite doesn't use the failpoint to induce
a crash that could legitimately happen in production.
What is does instead is to return early with an `Ok()`, so that the code
in Pageserver that handles duplicate layers (item 1) actually gets
exercised.
That "return early" would be a bug in the routine if it happened in
production.
So, the tests in the test suite are tests for their own sake, but don't
serve to actually regress-test any production behavior.
# Problem 2
Further, if production code _did_ (it nowawdays doesn't!) create a
duplicate layer, the code in Pageserver that handles the condition (item
1 above) is too little and too late:
* the code handles it by discarding the newer `struct Layer`; that's
good.
* however, on disk, we have already overwritten the old with the new
layer file
* the fact that we do it atomically doesn't matter because ...
* if the new layer file is not bit-identical, then we have a cache
coherency problem
* PS PageCache block cache: caches old bit battern
* blob_io offsets stored in variables, based on pre-overwrite bit
pattern / offsets
* => reading based on these offsets from the new file might yield
different data than before
# Solution
- Remove the test suite code pertaining to Problem 1
- Move & rename test suite code that actually tests RFC-27
crash-consistent layer map.
- Remove the Pageserver code that handles duplicate layers too late
(Problem 1)
- Use `RENAME_NOREPLACE` to prevent over-rename the file during
`.finish()`, bail with an error if it happens (Problem 2)
- This bailing prevents the caller from even trying to insert into the
layer map, as they don't even get a `struct Layer` at hand.
- Add `abort`s in the place where we have the layer map lock and check
for duplicates (Problem 2)
- Note again, we can't reach there because we bail from `.finish()` much
earlier in the code.
- Share the logic to clean up after failed `.finish()` between image
layers and delta layers (drive-by cleanup)
- This exposed that test `image_layer_rewrite` was overwriting layer
files in place. Fix the test.
# Future Work
This PR adds a new failure scenario that was previously "papered over"
by the overwriting of layers:
1. Start a compaction that will produce 3 layers: A, B, C
2. Layer A is `finish()`ed successfully.
3. Layer B fails mid-way at some `put_value()`.
4. Compaction bails out, sleeps 20s.
5. Some disk space gets freed in the meantime.
6. Compaction wakes from sleep, another iteration starts, it attempts to
write Layer A again. But the `.finish()` **fails because A already
exists on disk**.
The failure in step 5 is new with this PR, and it **causes the
compaction to get stuck**.
Before, it would silently overwrite the file and "successfully" complete
the second iteration.
The mitigation for this is to `/reset` the tenant.
## Problem
This was an oversight when adding heatmaps: because they are at the top
level of the tenant, they aren't included in the catch-all list & delete
that happens for timeline paths.
This doesn't break anything, but it leaves behind a few kilobytes of
garbage in the S3 bucket after a tenant is deleted, generating work for
the scrubber.
## Summary of changes
- During deletion, explicitly remove the heatmap file
- In test_tenant_delete_smoke, upload a heatmap so that the test would
fail its "remote storage empty after delete" check if we didn't delete
it.
RemoteTimelineClient maintains a copy of "next IndexPart" as a number of
fields which are like an IndexPart but this is not immediately obvious.
Instead of multiple fields, maintain a `dirty` ("next IndexPart") and
`clean` ("uploaded IndexPart") fields.
Additional cleanup:
- rename `IndexPart::disk_consistent_lsn` accessor
`duplicated_disk_consistent_lsn`
- no one except scrubber should be looking at it, even scrubber is a
stretch
- remove usage elsewhere (pagectl used by tests, metadata scan endpoint)
- serialize index part *before* the index upload operation
- avoid upload operation being retried because of serialization error
- serialization error is fatal anyway for timeline -- it can only make
transient local progress after that, at least the error is bubbled up
now
- gather exploded IndexPart fields into single actual
`UploadQueueInitialized::dirty` of which the uploaded snapshot is
serialized
- implement the long wished monotonicity check with the `clean`
IndexPart with an assertion which is not expected to fire
Continued work from #7860 towards next step of #6994.
in build logs we get a lot of lines for building the compute node images
because of verbose tar unpack. we know the sha256 so we don't need to
log the contents. my hope is that this will allow us more reliably use
the github live updating log view.
I suspected a wakeup could be lost with
`remote_storage::support::DownloadStream` if the cancellation and inner
stream wakeups happen simultaneously. The next poll would only return
the cancellation error without setting the wakeup. There is no lost
wakeup because the single future for getting the cancellation error is
consumed when the value is ready, and a new future is created for the
*next* value. The new future is always polled. Similarly, if only the
`Stream::poll_next` is being used after a `Some(_)` value has been
yielded, it makes no sense to have an expectation of a wakeup for the
*(N+1)th* stream value already set because when a value is wanted,
`Stream::poll_next` will be called.
A test is added to show that the above is true.
Additionally, there was a question of these cancellations and timeouts
flowing to attached or secondary tenant downloads. A test is added to
show that this, in fact, happens.
Lastly, a warning message is logged when a download stream is polled
after a timeout or cancellation error (currently unexpected) so we can
rule it out while troubleshooting.
## Problem
Page LSN is not set while VM update.
May be reason of test_vm_bits flukyness.
Buit more serious issues can be also caused by wrong LSN.
Related: https://github.com/neondatabase/neon/pull/7935
## Summary of changes
- In `apply_in_neon`, set the LSN bytes when applying records of type
`ClearVisibilityMapFlags`
## Problem
There was a bug in dynamic rate limiter, which exhausted CPU in proxy
and proxy wasn't able to accept any connections.
## Summary of changes
1. `if self.available > 1` -> `if self.available >= 1`
2. remove `timeout_at` to use just timeout
3. remove potential infinite loops which can exhaust CPUs.
## Problem
CreateImageLayersError and CompactionError had proper From
implementations, but compact_legacy was explicitly squashing all image
layer errors into an anyhow::Error anyway.
This led to errors like:
```

The storage controller has 'drop' APIs for tenants and nodes, for use in
situations where something weird has happened:
- node-drop is useful until we implement proper node decom, or if we
have a partially provisioned node that somehow gets registered with the
storage controller but is then dead.
- tenant-drop is useful if we accidentally add a tenant that shouldn't
be there at all, or if we want to make the controller forget about a
tenant without deleting its data. For example, if one uses the
tenant-warmup command with a bad tenant ID and needs to clean that up.
The drop commands require an `--unsafe` parameter, to reduce the chance
that someone incorrectly assumes these are the normal/clean ways to
delete things.
This PR also adds a convenience command for setting the time based
eviction parameters on a tenant. This is useful when onboarding an
existing tenant that has high resident size due to storage amplification
in compaction: setting a lower time based eviction threshold brings down
the resident size ahead of doing a shard split.

## Problem
Currently, we leave `index_part.json` objects from old generations
behind each time a pageserver restarts or a tenant is migrated. This
doesn't break anything, but it's annoying when a tenant has been around
for a long time and starts to accumulate 10s-100s of these.
Partially implements: #7043
## Summary of changes
- Add a new `pageserver-physical-gc` command to `s3_scrubber`
The name is a bit of a mouthful, but I think it makes sense:
- GC is the accurate term for what we are doing here: removing data that
takes up storage but can never be accessed.
- "physical" is a necessary distinction from the "normal" GC that we do
online in the pageserver, which operates at a higher level in terms of
LSNs+layers, whereas this type of GC is purely about S3 objects.
- "pageserver" makes clear that this command deals exclusively with
pageserver data, not safekeeper.
The keyspace utils like `is_rel_size_key` or `is_rel_fsm_block_key` and
many others are free functions and have to be either imported separately
or specified with the full path starting in `pageserver_api:🔑:`.
This is less convenient than if these functions were just inherent
impls.
Follow-up of #7890Fixes#6438

we use on CI, `test_pageserver_compaction_smoke` fails with division by
zero. fix it temporarily by allowing no vectored read happening. to be
cleaned when vectored get validation gets removed and the default value
can be changed.

In issue #5590 it was proposed to implement metrics for Azure blob
storage. This PR implements them except for the part that performs the
rename, which is left for a followup.
Closes#5590
The general partial backup idea is that each safekeeper keeps only one
partial segment in remote storage at a time. Sometimes this is not true,
for example if we uploaded object to S3 but got an error when tried to
remove the previous upload. In this case we still keep a list of all
potentially uploaded objects in safekeeper state.
This commit prints a warning to logs if there is too many objects in
safekeeper state. This is not expected and we should try to fix this
state, we can do this by running gc.
I haven't seen this being an issue anywhere, but printing a warning is
something that I wanted to do and forgot in initial PR.
## Problem
- Because GC exposes all errors as an anyhow::Error, we have
intermittent issues with spurious log errors during shutdown, e.g. in
this failure of a performance test
https://neon-github-public-dev.s3.amazonaws.com/reports/main/9300804302/index.html#suites/07874de07c4a1c9effe0d92da7755ebf/214a2154f6f0217a/
```
Gc failed 1 times, retrying in 2s: shutting down
```
GC really doesn't do a lot of complicated IO: it doesn't benefit from
the backtrace capabilities of anyhow::Error, and can be expressed more
robustly as an enum.
## Summary of changes
- Add GcError type and use it instead of anyhow::Error in GC functions
- In `gc_iteration_internal`, return GcError::Cancelled on shutdown
rather than Ok(()) (we only used Ok before because we didn't have a
clear cancellation error variant to use).
- In `gc_iteration_internal`, skip past timelines that are shutting
down, to avoid having to go through another GC iteration if we happen to
see a deleting timeline during a GC run.
- In `refresh_gc_info_internal`, avoid an error case where a timeline
might not be found after being looked up, by carrying an Arc<Timeline>
instead of a TimelineId between the first loop and second loop in the
function.
- In HTTP request handler, handle Cancelled variants as 503 instead of
turning all GC errors into 500s.
## Problem
In all cases, AncestorStopping is equivalent to Cancelled.
This became more obvious in
https://github.com/neondatabase/neon/pull/7912#discussion_r1620582309
when updating these error types.
## Summary of changes
- Remove AncestorStopping, always use Cancelled instead
This pull request adds necessary interfaces to deterministically create
scenarios we want to test. Simplify some test cases to use this
interface to make it stable + reproducible.
Compaction test will be able to use this interface. Also the upcoming
delete tombstone tests will use this interface to make test
reproducible.

This is a preparation for
https://github.com/neondatabase/neon/issues/6337.
The idea is to add FullAccessTimeline, which will act as a guard for
tasks requiring access to WAL files. Eviction will be blocked on these
tasks and WAL won't be deleted from disk until there is at least one
active FullAccessTimeline.
To get FullAccessTimeline, tasks call `tli.full_access_guard().await?`.
After eviction is implemented, this function will be responsible for
downloading missing WAL file and waiting until the download finishes.
This commit also contains other small refactorings:
- Separate `get_tenant_dir` and `get_timeline_dir` functions for
building a local path. This is useful for looking at usages and finding
tasks requiring access to local filesystem.
- `timeline_manager` is now responsible for spawning all background
tasks
- WAL removal task is now spawned instantly after horizon is updated
## Problem
- Initial size calculations tend to fail with `Bad state (not active)`
Closes: https://github.com/neondatabase/neon/issues/7911
## Summary of changes
- In `wait_lsn`, return WaitLsnError::Cancelled rather than BadState
when the state is Stopping
- Replace PageReconstructError's `Other` variant with a specific
`BadState` variant
- Avoid returning anyhow::Error from get_ready_ancestor_timeline -- this
was only used for the case where there was no ancestor. All callers of
this function had implicitly checked that the ancestor timeline exists
before calling it, so they can pass in the ancestor instead of handling
an error.
epoch is a historical and potentially confusing name. It semantically means
lastLogTerm from the raft paper, so let's use it.
This commit changes only internal namings, not public interface (http).
## Problem
Looking at several noisy shutdown logs:
- In https://github.com/neondatabase/neon/issues/7861 we're hitting a
log error with `InternalServerError(timeline shutting down\n'` on the
checkpoint API handler.
- In the field, we see initial_logical_size_calculation errors on
shutdown, via DownloadError
- In the field, we see errors logged from layer download code
(independent of the error propagated) during shutdown
Closes: https://github.com/neondatabase/neon/issues/7861
## Summary of changes
The theme of these changes is to avoid propagating anyhow::Errors for
cases that aren't really unexpected error cases that we might want a
stacktrace for, and avoid "Other" error variants unless we really do
have unexpected error cases to propagate.
- On the flush_frozen_layers path, use the `FlushLayerError` type
throughout, rather than munging it into an anyhow::Error. Give
FlushLayerError an explicit from_anyhow helper that checks for timeline
cancellation, and uses it to give a Cancelled error instead of an Other
error when the timeline is shutting down.
- In logical size calculation, remove BackgroundCalculationError (this
type was just a Cancelled variant and an Other variant), and instead use
CalculateLogicalSizeError throughout. This can express a
PageReconstructError, and has a From impl that translates cancel-like
page reconstruct errors to Cancelled.
- Replace CalculateLogicalSizeError's Other(anyhow::Error) variant case
with a Decode(DeserializeError) variant, as this was the only kind of
error we actually used in the Other case.
- During layer download, drop out early if the timeline is shutting
down, so that we don't do an `error!()` log of the shutdown error in
this case.
Updates the `tokio-epoll-uring` dependency.
There is [only one change](342ddd197a...08ccfa94ff),

Part of #7889.
Consider the following sequence of migration:
```
1. user starts compute
2. force migrate to v2
3. user continues to write data
```
At the time of (3), the compute node is not aware that the page server
does not contain replication states any more, and might continue to
ingest neon-file records into the safekeeper. This will leave the
pageserver store a partial replication state and cause some errors. For
example, the compute could issue a deletion of some aux files in v1, but
this file does not exist in v2. Therefore, we should ignore all these
errors until everyone is migrated to v2.
Also note that if we see this warning in prod, it is likely because we
did not fully suspend users' compute when flipping the v1/v2 flag.

## Problem
In 4ce6e2d2fc we added a warning when progress stats don't look right at
the end of a secondary download pass.
This `Correcting drift in progress stats` warning fired in staging on a
pageserver that had been doing some disk usage eviction.
The impact is low because in the same place we log the warning, we also
fix up the progress values.
## Summary of changes
- When we skip downloading a layer because it was recently evicted,
update the progress stats to ensure they still reach a clean complete
state at the end of a download pass.
- Also add a log for evicting secondary location layers, for symmetry
with attached locations, so that we can clearly see when eviction has
happened for a particular tenant's layers when investigating issues.
This is a point fix -- the code would also benefit from being refactored
so that there is some "download result" type with a Skip variant, to
ensure that we are updating the progress stats uniformly for those
cases.
