Today when a replica shard detects a new primary shard (via a primary
term transition), we roll the translog generation. However, the
mechanism that we are using here is by reaching through the engine to
the translog directly. By poking all the way through rather than asking
the engine to manage the roll for us we miss:
- taking a read lock in the engine while the roll is occurring
- trimming unreferenced readers
This commit addresses this by asking the engine to roll the translog
generation for us.

The test expects suggest times in milliseconds that are strictly
positive. Internally they are measured in nanos, it is possible that on
really fast execution this is rounded to 0L, so this should also be an
accepted value.
Closes#28543
We now read the plugin descriptor when removing an old plugin. This is
to check if we are removing a plugin that is extended by another
plugin. However, when reading the descriptor we enforce that it is of
the same version that we are. This is not the case when a user has
upgraded Elasticsearch and is now trying to remove an old plugin. This
commit fixes this by skipping the version enforcement when reading the
plugin descriptor only when removing a plugin.

A shard is fully baked when it moves to POST_RECOVERY. There is no need to do an extra refresh on shard activation again as the shard has already been refreshed when it moved to POST_RECOVERY.
* Move to non-deprecated XContentHelper.createParser(...)
This moves away from one of the now-deprecated XContentHelper.createParser
methods in favor of specifying the deprecation logger at parser creation time.
Relates to #28449
Note that this doesn't move all the `createParser` calls because some of them
use the already-deprecated method that doesn't specify the XContentType.
* Remove the deprecated (and now non-needed) createParser method
The initializer and afterthought were not having their types
appropriately cast which is necessary with expressions which in turn
caused values to be popped off the stack that were null.
If you call `getDates()` on a long or date type field add a deprecation
warning to the response and log something to the deprecation logger.
This *mostly* worked just fine but if the deprecation logger happens to
roll then the roll will be performed with the script's permissions
rather than the permissions of the server. And scripts don't have
permissions to, say, open files. So the rolling failed. This fixes that
by wrapping the call the deprecation logger in `doPriviledged`.
This is a strange `doPrivileged` call because it doens't check
Elasticsearch's `SpecialPermission`. `SpecialPermission` is a permission
that no-script code has and that scripts never have. Usually all
`doPrivileged` calls check `SpecialPermission` to make sure that they
are not accidentally acting on behalf of a script. But in this case we
are *intentionally* acting on behalf of a script.
Closes#28408
Currently when failing a shard we also mark it as stale (eg. remove its
allocationId from from the InSync set). However in some cases, we need
to be able to fail shards but keep them InSync set. This commit adds
such capacity. This is a preparatory change to make the primary-replica
resync less lenient.

* Consolidates provision steps so it's more clear which steps are
applied to all boxes
* Removes duplicate configuration that was being stomped
* Ensure rsync, a dependency for platform steps, is installed on linux
* Ruby style changes

Gradle 4.5 now hides immutable task dependencies. We previously copied
the existing dependencies from the builtin test task to the
randomizedtesting task. This commit adds testClasses as an extra
dependency of the randomizedtesting task, to ensure the classes are
built.
ava.time has the functionality needed to deal with timezones with varying
offsets correctly, but it also has a bunch of methods that silently let you
forget about the hard cases, which raises the risk that we'll quietly do the
wrong thing at some point in the future.
This change adds the trappy methods to the list of forbidden methods to try and
help stop this from happening.
It also fixes the only use of these methods in the codebase so far:
IngestDocument#deepCopy() used ZonedDateTime.of() which may alter the offset of
the given time in cases where the offset is ambiguous.
This commit switches all the modules and server test code to use the
non-deprecated `ParseField.match` method, passing in the parser's deprecation
handler or the logging deprecation handler when a parser is not available (like
in tests).

Today the correctness of synced-flush is guaranteed by ensuring that
there is no ongoing indexing operations on the primary. Unfortunately, a
replica might fall out of sync with the primary even the condition is
met. Moreover, if synced-flush mistakenly issues a sync_id for an out of
sync replica, then that replica would not be able to recover from the
primary. ES prevents that peer-recovery because it detects that both
indexes from primary and replica were sealed with the same sync_id but
have a different content. This commit modifies the synced-flush to not
issue sync_id for out of sync replicas. This change will report the
divergence issue earlier to users and also prevent replicas from getting
into the "unrecoverable" state.
Relates #10032
We do want to keep this functionality in the future and we provide support for it.
This change is a first step towards replacing the `synonym` token filter with `synonym_graph`.
The primary currently replicates writes to all other shard copies as soon as they're added to the routing table. Initially those shards are not even ready yet to receive these replication requests, for example when undergoing a file-based peer recovery. Based on the specific stage that the shard copies are in, they will throw different kinds of exceptions when they receive the replication requests. The primary then ignores responses from shards that match certain exception types. With this mechanism it's not possible for a primary to distinguish between a situation where a replication target shard is not allocated and ready yet to receive requests and a situation where the shard was successfully allocated and active but subsequently failed.
This commit changes replication so that only initializing shards that have successfully opened their engine are used as replication targets. This removes the need to replicate requests to initializing shards that are not even ready yet to receive those requests. This saves on network bandwidth and enables features that rely on the distinction between a "not-yet-ready" shard and a failed shard.
Currently the callouts for this section are below all the examples, making it
harder to relate them to the snippets. Instead they should be moved closer
to the examples.
* [DOCS] expand examples on providing mappings for create index and put mapping
The create index API and put mappings API docs the for high-level Java REST client didn't have a lot of info on how to provide mappings. This commit adds some examples.
This assertion does not hold if engine is flushed between the invocation
of translog.uncommittedSizeInBytes and translog.uncommittedOperations.
These two values can be calculated from different commits.
If the translog flush threshold is too small (eg. smaller than the
translog header), we may repeatedly flush even there is no uncommitted
operation because the shouldFlush condition can still be true after
flushing. This is currently avoided by adding an extra guard against the
uncommitted operations. However, this extra guard makes the shouldFlush
complicated. This commit replaces that extra guard by a lower bound for
translog flush threshold. We keep the lower bound small for convenience
in testing.

This commit splits the async execution documentation into 2 parts, one
for the async method itself and one for the action listener. This allows
to add more doc and to use CountDownLatches in doc tests to wait for
asynchronous operations to be completed before moving to the next test.
It also renames few files.
Related to #28457
Similarly to other documentation tests in the high level client, the
asynchronous operation like update, index or delete can make the test
fail if it sneak in between the middle of another operation.
This commit moves the async doc tests to be the last ones executed and
adds assert busy loops to ensure that the asynchronous operations are
correctly terminated.

Persistent tasks are build on top of node tasks and provide functionality to restart a task to run on a different coordination node in case the coordinating node is no longer available.
It is up to a persistent task implementation to keep track of status, so that in case the task is restarted, the task can continue were it left off before it was restarted.
