* 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.
* Add migrate note
Moves the check for tiny polygons earlier in the test. It turned out
that polygons can be so tiny that we cannot even figure out their
orientation.

* Set mappings when creating indices in SuggestSearchIT
These tests don't test dynamic mapping, so they can use preset mappings. This
removes the possibility they may fail due to the mapping not being available
since mapping updates are asynchronous.
Resolves#39315
* Wrap creates in assertAcked
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.
Closes#35982
Adjust the retention lease sync actions so that they do not respect the
`index.write.wait_for_active_shards` setting on an index, allowing them to sync
retention leases even if insufficiently many shards are currently active to
accept writes.

* The lambda invoked by the `lockedExecutor` eventually gets JITed (which runs a static initializer that we will suspend in with a very tiny chance).
* Fixed by creating the `Runnable` in the main test thread and using the same instance in all threads
* Closes#35686
We tripped this assertion three times for the last two weeks. However,
it only says "this IndexWriter is closed" without the actual cause.
```
[2019-02-14T11:46:31,144][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [node-1] fatal error in thread [elasticsearch[node-1][generic][T#2]], exiting
java.lang.AssertionError: unexpected failure while replicating translog entry: org.apache.lucene.store.AlreadyClosedException: this IndexWriter is closed
```
This change replaces an assert with an AssertionError so that we will
have the actual cause in the next build failures.

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.
We validate HW parameters (namely, window > 2 * period) when parsing
the XContent... but that means transport clients can configure bad
params.
This change allows model to validate the window and throw an
exception if they wish.
It also makes some test changes:
- removes testBadModelParams(), which was a junk test (didn't do
anything), and bad param checking is done elsewhere in units tests
- Fixes one of the windows in testHoltWintersNotEnoughData()
- Ensures the period in testHoltWintersNotEnoughData() is >> window
- Removes `setTypes()` since that's deprecated
This fixes#39245. Currently it is possible in this test that the clear
session call times-out. This means that the index commit will not be
released and there will be an assertion triggered in the test teardown.
This commit ensures that we wipe the leader index in the test to avoid
this assertion.
It is okay if the clear session call times-out in normal usage. This
scenario is unavoidable due to potential network issues. We have a local
timeout on the leader to clean it up when this scenario happens.
The assertBusy() that waits the default 10 seconds for a
datafeed to complete very occasionally times out on slow
machines. This commit increases the timeout to 60 seconds.
It will almost never actually take this long, but it's
better to have a timeout that will prevent time being
wasted looking at spurious test failures.
This test should no longer pass when the functionality it is intended to
test is broken, as it now indexes a number of documents and verifies
that the index is staying on the same step until after indexing and
replication of those documents is finished. This prevents the test from
passing if the leader index progresses in its lifecycle during that time.
This test failed once in a very long time with the assertion
that there is no document for the `non_existing_job` in the
state index. I could not see how that is possible and I cannot
reproduce. With this commit the failure message will reveal
some examples of the left behind docs which might shed a light
about what could go wrong.
With this commit we remove all usages of the deprecated method
`ExceptionsHelper#detailedMessage` in tests. We do not address
production code here but rather in dedicated follow-up PRs to keep the
individual changes manageable.
Relates #19069
With this commit we change the script that generates the release notes
for Elasticsearch to align with the docs standards in the following
aspects:
* The release notes title changes to include the product name
* The link text to the breaking changes page is explicitly defined
Relates #39155
This commit makes `TransformIntegrationTests` into a standard integration test, as
opposed to using `TimeWarp`, which registers the mock component
`ScheduleEngineTriggerMock` to trigger watches.
The simplification may help with flakiness we've observed `TimeWarp, as in #37882.
The SchedulerEngine is used in several places in our code and not all
of these usages properly stopped the SchedulerEngine, which could lead
to test failures due to leaked threads from the SchedulerEngine. This
change adds stopping to these usages in order to avoid the thread leaks
that cause CI failures and noise.
Closes#38875
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.
MatrixStatsResults is the "final" result object, and runs an additional
computation in it's ctor to calculate covariance, etc. This means
it should only run on the final reduction instead of on every reduce.
Sleeps in tests smell funny, and we try to avoid them to the extent
possible. We are using a small one in a CCR test. This commit clarifies
the purpose of that sleep by adding a comment explaining it. We also
removed a hard-coded value from the test, that if we ever modified the
value higher up where it was set, we could end up forgetting to change
the value here. Now we ensure that these would move in lock step if we
ever maintain them later.
