We keep adding the current primary term to operations for which we do not assign a sequence
number. This does not make sense anymore as all operations which we care about have
sequence numbers now. The goal of this commit is to clean things up in InternalEngine and
reduce the complexity.
* There's no need to have the trie iterator hold another reference to the request object (which could be huge, see #44564)
* Also removed unused boolean field from trie node
Previously, we use ThreadPoolStats to ensure that the scheduledRefresh
triggered by the internal refresh setting update is executed before we
index a new document. With that change (#40387), this test did not fail for
the last 3 months. However, using ThreadPoolStats is not entirely watertight
as both "active" and "queue" count can be 0 in a very small interval
when ThreadPoolExecutor pulls a task from the queue but before marking
the corresponding worker as active (i.e., lock it).
Closes#39565
Adds a `waitForEvents(Priority.LANGUID)` to the cluster health request in
`ESIntegTestCase#waitForRelocation()` to deal with the case that this health
request returns successfully despite the fact that there is a pending reroute task which
will relocate another shard.

Today the lag detector may remove nodes from the cluster if they fail to apply
a cluster state within a reasonable timeframe, but it is rather unclear from
the default logging that this has occurred and there is very little extra
information beyond the fact that the removed node was lagging. Moreover the
only forewarning that the lag detector might be invoked is a message indicating
that cluster state publication took unreasonably long, which does not contain
enough information to investigate the problem further.
This commit adds a good deal more detail to make the issues of slow nodes more
prominent:
- after 10 seconds (by default) we log an INFO message indicating that a
publication is still waiting for responses from some nodes, including the
identities of the problematic nodes.
- when the publication times out after 30 seconds (by default) we log a WARN
message identifying the nodes that are still pending.
- the lag detector logs a more detailed warning when a fatally-lagging node is
detected.
- if applying a cluster state takes too long then the cluster applier service
logs a breakdown of all the tasks it ran as part of that process.
Currently, we do not handle READ or WRITE events until the channel
connection process is complete. However, the external write queue path
allows a write to be attempted when the conneciton is not complete. This
commit closes the loophole and only queues write operations when the
connection process is not complete.
* Dry up code for creating simple `ActionRunnable` a little
* Shorten some other code around `ActionListener` usage, in particular
when wrapping it in a `TransportResponseListener`
* As a result of #44096 this test shouldn't fail anymore on `master` and `7.4`+ so we should reenable it there
* For older versions we won't backport that change so the tests should stay disabled there
* Closes#44671
Reading up on #33673 it looks like parts of these tests have been reworked and
there is no intention to fix the remains on 7.x, so I think we can remove the
entire test.
The task that TaskManager#register returns cannot be null. The method
enforces that it is not null after calling request#createTask. It is
then needless to check for null in the listener later. Also, added the
call to the delegate listener in a finally block, just to make sure.
* We shouldn't be recreating wrapped REST handlers over and over for every request. We only use this hook in x-pack and the wrapper there does not have any per request state.
This is inefficient and could lead to some very unexpected memory behavior
=> I made the logic create the wrapper on handler registration and adjusted the x-pack wrapper implementation to correctly forward the circuit breaker and content stream flags
The Get Users API also returns users form the restricted realm or built-in users,
as we call them in our docs. One can also change the passwords of built-in
users with the Change Password API
Most of the circuit breaker settings are dynamically configurable.
However, `indices.breaker.total.use_real_memory` is not. With this
commit we add a clarifying note that this specific setting is static.
Closes#44974
A mismatched configuration between the IdP and SP will often result in
SAML authentication attempts failing because the audience condition is
not met (because the IdP and SP disagree about the correct form of the
SP's Entity ID).
Previously the error message in this case did not provide sufficient
information to resolve the issue because the IdP's expected audience
would be truncated if it exceeeded 32 characters. Since the error did
not provide both IDs in full, it was not possible to determine the
correct fix (in detail) based on the error alone.
This change expands the message that is included in the thrown
exception, and also adds additional logging of every failed audience
condition, with diagnostics of the match failure.
Backport of: #44334
When finding nodes in a connected cluster for cross cluster
search the requests to get cluster state on the connected
cluster should be made in the system context because
logically they are equivalent to checking a single detail
in the local cluster state and should not require that the
user who made the request that is using this method in its
implementation is authorized to view the entire cluster
state.
Fixes#43974
* Create S3 Third Party Test Task that Covers the S3 CLI Tool
* Adjust snapshot cli test tool tests to work with real S3
* Build adjustment
* Clean up repo path before testing
* Dedup the logic for asserting path contents by using the correct utility method here that somehow became unused
* We should not create a new wrapper object if there's no bytes in the `ByteBuf`
* We should not create a new wrapped `ByteBuf` if it can't contain a message anyway because it doesn't even have enough bytes for a header left
