In most of the places we avoid creating the `.security` index (or updating the mapping)
for read/search operations. This is more of a nit for the case of the getRole call,
that fixes a possible mapping update during a get role, and removes a dead if branch
about creating the `.security` index.
The follower won't always have the same history as the leader for its
soft-deletes retention can be different. However, if some operation
exists on the history of the follower, then the same operation must
exist on the leader. This change relaxes the history check in
ShardFollowTaskReplicationTests.
Closes#39093
This commit introduces the retention leases to ESIndexLevelReplicationTestCase,
then adds some tests verifying that the retention leases replication works
correctly in spite of the presence of the primary failover or out of order
delivery of retention leases sync requests.
Relates #37165
This commit attempts to remove the retention leases on the leader shards
when unfollowing an index. This is best effort, since the leader might
not be available.
This test had been disabled because of test failures, but it only affected the
6.x branch. The fix for 6.x is at #39054. On master/7.x/7.0 we can reenable the
test as-is.
This defaults to "true" (current behavior) and will throw an exception
if there is a property that cannot be recognized. If "false", it will
ignore anything unrecognizable.
Today's calculation of the maximum number of shards per attribute is rather
convoluted. This commit clarifies that it returns
ceil(shardCount/numberOfAttributes).
Blob store compression was not enabled for some of the files in
snapshots due to constructor accessing sub-class fields. Fixed to
instead accept compress field as constructor param. Also fixed chunk
size validation to work.
Deprecated repositories.fs.compress setting as well to be able to unify
in a future commit.
* A few warnings could be observed in test logs about `NoSuchElementException` being thrown in `InboundChannelBuffer#sliceBuffersTo`.
These were the result of calls to this method after the relevant channel and hence the buffer was closed already as a result of a failed IO operation.
* Fixed by adding the necessary guard statements to break out in these cases. I don't think there is a need here to do any additional error handling since `eventHandler.postHandling(channelContext);` at the end of the `processKey`
call in the main selection loop handles closing channels and invoking callbacks for writes that failed to go through already.
The watcher trigger service could attempt to modify the perWatchStats
map simultaneously from multiple threads. This would cause the
internal state to become inconsistent, in particular the count()
method may return an incorrect value for the number of watches.
This changes replaces the implementation of the map with a
ConcurrentHashMap so that its internal state remains consistent even
when accessed from mutiple threads.
Resolves: #39087
Fixes an error in median calculation in
MedianAbsoluteDeviationAggregatorTests for odd number of sample points,
which causes some rare test failures.
Fixes#38937
Currently remote compression and ping schedule settings are dynamic.
However, we do not listen for changes. This commit adds listeners for
changes to those two settings. Additionally, when those settings change
we now close existing connections and open new ones with the settings
applied.
Fixes#37201.
Sometimes we turn objects into strings for logging or debugging using
`toString()`, but the default implementation is often unhelpful. This change
improves on this in two places I ran into recently.
the RethrottleTests assumed that tasks that were
unprepared to rethrottle would bubble up into the
Rethrottle response as an ElasticsearchException
wrapping an IllegalArgumentException. This seems to
have changed to potentially involve further levels of
wrapping.
This change makes the retry logic more resilient to
arbitrary nesting of the underlying IllegalArgumentException
This ensures we do not attempt to parse non english locale dates
in FIPS mode. The error, originally assumed to affect only Joda,
affects Java time in the same manner and manifests only with the
version of BouncyCastle FIPS certified provider we use in tests.
The upstream issue https://github.com/bcgit/bc-java/issues/405
indicates that the behavior is resolved in later versions of the
BouncyCastle library and should be tested again when the new
versions become FIPS 140 certified
The ML memory tracker does searches against ML results
and config indices. These searches can be asynchronous,
and if they are running while the node is closing then
they can cause problems for other components.
This change adds a stop() method to the MlMemoryTracker
that waits for in-flight searches to complete. Once
stop() has returned the MlMemoryTracker will not kick
off any new searches.
The MlLifeCycleService now calls MlMemoryTracker.stop()
before stopping stopping the node.
Fixes#37117
This test had a bug. We attempt to allow only the primary to be
allocated, to force all replicas to recovery from the primary after we
had set the state of the retention leases on the primary. However, in
building the index settings, we were overwriting the settings that
exclude the replicas from being allocated. This means that some of the
replicas would end up assigned and rather than receive retention leases
during recovery, they would be part of the replication group receiving
retention leases as they are manipulated. Since retention lease renewals
are only synced periodically, this means that the replica could be
lagging a little behind in some cases leading to an assertion tripping
in the test. This commit addresses this by ensuring that the replicas
are indeed not allocated until after the retention leases are done being
manipulated on the replica. We did this by not overwriting the exclude
settings.
Closes#39105
These two changes are interlinked.
Before this change unsetting ML upgrade mode would wait for all
datafeeds to be assigned and not waiting for their corresponding
jobs to initialise. However, this could be inappropriate, if
there was a reason other that upgrade mode why one job was unable
to be assigned or slow to start up. Unsetting of upgrade mode
would hang in this case.
This change relaxes the condition for considering upgrade mode to
be unset to simply that an assignment attempt has been made for
each ML persistent task that did not fail because upgrade mode
was enabled. Thus after unsetting upgrade mode there is no
guarantee that every ML persistent task is assigned, just that
each is not unassigned due to upgrade mode.
In order to make setting upgrade mode work immediately after
unsetting upgrade mode it was then also necessary to make it
possible to stop a datafeed that was not assigned. There was
no particularly good reason why this was not allowed in the past.
It is trivial to stop an unassigned datafeed because it just
involves removing the persistent task.
The parseMillis method was able to work on formats without timezones by
falling back to UTC. The Date Formatter interface did not support this, as
the calling code was using the `Instant.from` java time API.
This switches over to an internal method which adds UTC as a timezone.
Closes#39067
* Don't Ping on Handshake Connection
* It does not make sense to run pings on the handshake connection
* Set the ping interval to `-1` to deactivate pings on it
Follow up to #38999, this commit re-enables backwards-compatibility REST tests
for `before`, `after` and `overlapping` filters against versions 7.1 and up.
- Notes that you can adjust the `s3.client.*.endpoint` setting to point to a
repository held on an S3-compatible service.
- Notes that the default is `s3.amazonaws.com` and not to auto-detect the
endpoint.
- Reformats docs to width.
