Currently there are two security tests that specifically target the
netty security transport. This PR moves the client authentication tests
into `AbstractSimpleSecurityTransportTestCase` so that the nio transport
will also be tested.
Additionally the work to build transport configurations is moved out of
the netty transport and tested independently.
This changes the name of the internal security index to ".security-7",
but supports indices that were upgraded from earlier versions and use
the ".security-6" name.
In all cases, both ".security-6" and ".security-7" are considered to
be restricted index names regardless of which name is actually in use
on the cluster.
Backport of: #39337
Some small fix for the `x-pack` rest api spec.
* In both `security.enable_user.json` and `security.disable_user.json`
the `username` parameter was `false` instead of `true`
(the documentation is already correct).
* In `security.get_privileges.json` there were missing all the
possible paths since the path parameters are not required.
This fix aligns the document with the rest of the spec,
where all the possible combinations are listed.
It is possible that the Unfollow API may fail to release shard history
retention leases when unfollowing, so this needs to be handled by the
ILM Unfollow action. There's nothing much that can be done automatically
about it from the follower side, so this change makes the ILM unfollow
action simply ignore those failures.
Since #39006, we should either remove `testWaitForPendingSeqNo`
or adjust it not to wait for the pending operations. This change picks
the latter.

`withLocalReduction` is confusing as `local` effectively means "local
to the remote clusters" rather than "local the coordinating node" where
the method is executed. I propose we rename the method to
`crossClusterSearch` which better resembles what the static method is
used for.
While running these commands from alias, facing issues using kill `cat pid`, In some situations, the more compact:
```
pkill -F /var/run/myProcess.pid
```
is the way to go.
We have been calling `reduce` against completion suggestions twice, once
in `SearchPhaseController#reducedQueryPhase` where all suggestions get
reduced, and once more in `SearchPhaseController#sortDocs` where we
add the top completion suggestions to the `TopDocs` so their docs can
be fetched. There is no need to do reduction twice. All suggestions can
be reduced in one call, then we can filter the result and pass only the
already reduced completion suggestions over to `sortDocs`. The small
important detail is that `shardIndex`, which is currently used only
to fetch suggestions hits, needs to be set before the first reduction,
hence outside of `sortDocs` where we have been doing it until now.
This change is a backport of #39252
- Fixes TokenBackwardsCompatibilityIT: Existing tests seemed to made
the assumption that in the oneThirdUpgraded stage the master node
will be on the old version and in the twoThirdsUpgraded stage, the
master node will be one of the upgraded ones. However, there is no
guarantee that the master node in any of the states will or will
not be one of the upgraded ones.
This class now tests:
- That we can generate and consume tokens before we start the
rolling upgrade.
- That we can consume tokens generated in the old cluster during
all the stages of the rolling upgrade.
- That while on a mixed cluster, when/if the master node is
upgraded, we can generate, consume and refresh a token
- That after the rolling upgrade, we can consume a token
generated in an old cluster and can invalidate it so that it
can't be used any more.
- Ensures that during the rolling upgrade, the upgraded nodes have
the same configuration as the old nodes. Specifically that the
file realm we use is explicitly named `file1`. This is needed
because while attempting to refresh a token in a mixed cluster
we might create a token hitting an old node and attempt to refresh
it hitting a new node. If the file realm name is not the same, the
refresh will be seen as being made by a "different" client, and
will, thus, fail.
- Renames the Authentication variable we check while refreshing a
token to be clientAuth in order to make the code more readable.
Some of the above were possibly causing the flakiness of #37379
Checks that the core coordination algorithm implemented as part of Zen2 (#32006) supports
linearizable semantics. This commit adds a linearizability checker based on the Wing and Gong
graph search algorithm with support for compositional checking and activates these checks for all
CoordinatorTests.
Today we do not bubble up exceptions when processing NoOps but always
treat them as document-level failures. This incorrect treatment causes
the assert_no_failure being tripped in peer-recovery if IndexWriter was
closed exceptionally before.

Today when users upgrade to 7.0, existing indices will automatically
switch to soft-deletes without an opt-out option. With this change,
we only enable soft-deletes by default for new indices.

This commit is the final piece of the integration of CCR with retention
leases. Namely, we periodically renew retention leases and advance the
retaining sequence number while following.
* Remove Hipchat support from Watcher (#39199)
Hipchat has been shut down and has previously been deprecated in
Watcher (#39160), therefore we should remove support for these actions.

This fixes a bug in the sensing of the current OS family in the test cluster
formation code. Previously all builds would assume every environment
was windows and would jump to using the windows zip build. This fixes
the OS sensing code as well as updates some tests to account for
different build flavors.
Backport of #38457
With this change, we won't wait for the local checkpoint to advance to
the max_seq_no before starting phase2 of peer-recovery. We also remove
the sequence number range check in peer-recovery. We can safely do these
thanks to Yannick's finding.
The replication group to be used is currently sampled after indexing
into the primary (see `ReplicationOperation` class). This means that
when initiating tracking of a new replica, we have to consider the
following two cases:
- There are operations for which the replication group has not been
sampled yet. As we initiated the new replica as tracking, we know that
those operations will be replicated to the new replica and follow the
typical replication group semantics (e.g. marked as stale when
unavailable).
- There are operations for which the replication group has already been
sampled. These operations will not be sent to the new replica. However,
we know that those operations are already indexed into Lucene and the
translog on the primary, as the sampling is happening after that. This
means that by taking a snapshot of Lucene or the translog, we will be
getting those ops as well. What we cannot guarantee anymore is that all
ops up to `endingSeqNo` are available in the snapshot (i.e. also see
comment in `RecoverySourceHandler` saying `We need to wait for all
operations up to the current max to complete, otherwise we can not
guarantee that all operations in the required range will be available
for replaying from the translog of the source.`). This is not needed,
though, as we can no longer guarantee that max seq no == local
checkpoint.

Today this test catches an exception and asserts that its proximate cause has
message `Random IOException` but occasionally this exception is wrapped two
layers deep, causing the test to fail. This commit adjusts the test to look at
the root cause of the exception instead.

In integration tests where `setBootstrapMasterNodeIndex()` is used in
combination with `autoMinMasterNodes = false` the cluster can start
bootstrapping once the number of nodes set with the
`setBootstrapMasterNodeIndex` have been started but it's not ensured
that all nodes have successfully joined to form the cluster.
This behaviour was introduced with 5db7ed22a0
and in order to ensure that the cluster is properly formed before proceeding
with the integration test, use `ensureStableCluster()` with the
appropriate number of expected nodes.
Fixes: #39220
In #39224 we made shard history retention lease syncing ignore the
`index.write.wait_for_active_shards` setting on the index, and added a test
that showed that it was ignored. However the test as merged actually creates a
green index, so the `wait_for_active_shards` setting has no effect. This change
adjusts the test to create a yellow index to verify that
`wait_for_active_shards` really is ignored.
when dealing with TimeoutException
The `IndexFollowingIT#testDeleteLeaderIndex()`` test failed,
because a NPE was captured as fatal error instead of an IndexNotFoundException.
Closes#39308
This fixes an issue where a messy master election might prevent shard allocation to properly
proceed. I've encountered this in failing CI tests when we were bootstrapping multiple nodes. Tests
would sometimes time out on an `ensureGreen` after an unclean master election. The reason for
this is how the async shard information fetching works and how the clean-up logic in
GatewayAllocator is integrated with the rest of the system. When a node becomes master, it will, as
part of the first cluster state update where it becomes master, already try allocating shards (see
`JoinTaskExecutor`, in particular the call to `reroute`). This process, which runs on the
MasterService thread, will trigger async shard fetching. If the node is still processing an earlier
election failure in ClusterApplierService (e.g. due to a messy election), that will possibly trigger the
clean-up logic in GatewayAllocator after the shard fetching has been initiated by MasterService,
thereby cancelling the fetching, which means that no subsequent reroute (allocation) is triggered
after the shard fetching results return. This means that no shard allocation will happen unless the
user triggers an explicit reroute command. The bug imo is that GatewayAllocator is called from both
MasterService and ClusterApplierService threads, with no clear happens-before relation. The fix
here makes it so that the clean-up logic is also run on the MasterService thread instead of the
ClusterApplierService thread, reestablishing a clear happens-before relation. Note that testing this
is tricky. With the newly added test, I can quite often reproduce this by adding `Thread.sleep(10);`
in ClusterApplierService (to make sure it does not go too quickly) and adding `Thread.sleep(50);` in
`TransportNodesListGatewayStartedShards` to make sure that shard state fetching does not go too
quickly either.
Note that older versions of Zen discovery are affected by this as well, but did not exhibit this issue
as often because master elections are much slower there.
There have been intermittent failures where either
LDAP server could not be started or KDC server could
not be started causing failures during test runs.
`KdcNetwork` class from Apache kerby project does not set reuse
address to `true` on the socket so if the port that we found to be free
is in `TIME_WAIT` state it may fail to bind. As this is an internal
class for kerby, I could not find a way to extend.
This commit adds a retry loop for initialization. It will keep
trying in an await busy loop and fail after 10 seconds if not
initialized.

Adjust the retention lease sync actions so that they do not respect the

We tripped this assertion three times for the last two weeks. However,

This change replaces an assert with an AssertionError so that we will

Finally! This commit should fix the issues with the CCR retention lease
that has been plaguing build failures. The issue here is that we are
trying to prevent the clear session requests from being executed until
after we have been able to validate that retention leases are being
renewed. However, we were only blocking the clear session requests but
not blocking them when they are proxied through another node. This
commit addresses that.
Relates #39268
This commit changes the sort order of shard stats that are collected in
CCR retention lease integration tests. This change is done so that
primaries appear first in sort order.
This test fails rarely but it is flaky in its current form. The problem
here is that we lack a guarantee on the retention leases having been
synced to all shard copies. We need to sleep long enough to ensure that
that occurs, and then we can sample the retention leases, possibly sleep
again (we usually will not have too since the first sleep will have been
long enough to allow a sync and a renewal to happen, if one was going to
happen), and the sample the retention leases for comparison.
Closes#39331
The shard logged here is the leader shard but it should be the follower
shard since this background retention lease renewal is happening on the
follower side. This commit fixes that.
This commit simplifies the use of transport mocking in the CCR retention
lease integration tests. Instead of adding a send rule between nodes, we
add a default send rule. This greatly simplifies the code here, and
speeds the test up a little bit too.
