This is related to #27260. Currently for the SSLDriver we allocate a
dedicated network write buffer and encrypt the data into that buffer one
buffer at a time. This requires constantly switching between encrypting
and flushing. This commit adds a dedicated outbound buffer for SSL
operations that will internally allocate new packet sized buffers as
they are need (for writing encrypted data). This allows us to totally
encrypt an operation before writing it to the network. Eventually it can
be hooked up to buffer recycling.
This commit also backports the following commit:
Handle WRAP ops during SSL read
It is possible that a WRAP operation can occur while decrypting
handshake data in TLS 1.3. The SSLDriver does not currently handle this
well as it does not have access to the outbound buffer during read call.
This commit moves the buffer into the Driver to fix this issue. Data
wrapped during a read call will be queued for writing after the read
call is complete.
IntervalsSources can throw IllegalArgumentExceptions if they would produce
too many disjunctions. To mitigate against this when building random
sources, we limit the depth of the randomly generated source to four
nested sources
Fixes#41402
* Add Repository Consistency Assertion to SnapshotResiliencyTests (#40857)
* Add Repository Consistency Assertion to SnapshotResiliencyTests
* Add some quick validation on not leaving behind any dangling metadata or dangling indices to the snapshot resiliency tests
* Added todo about expanding this assertion further
* Fix SnapshotResiliencyTest Repo Consistency Check (#41332)
* Fix SnapshotResiliencyTest Repo Consistency Check
* Due to the random creation of an empty `extra0` file by the Lucene mockFS we see broken tests because we use the existence of an index folder in assertions and the index deletion doesn't go through if there are extra files in an index folder
* Fixed by removing the `extra0` file and resulting empty directory trees before asserting repo consistency
* Closes#41326
* Reenable SnapshotResiliency Test (#41437)
This was fixed in https://github.com/elastic/elasticsearch/pull/41332
but I forgot to reenable the test.
* fix compile on java8
We use Bouncy Castle to verify signatures when installing official
plugins. This leads to illegal access warnings because Bouncy Castle
accesses the Sun security provider constructor. This commit adds an
add-opens flag to suppress this illegal access.
This commit bumps the bundled JDK to version 12.0.1. Note that we had to
add a new pattern here as Oracle has changed the source of the
builds. This commit will be backported to 6.7 in a different form to
bump the bundled JDK in the Docker images too.
We had been obtaining JDK distributions from download.java.net. This
site is now presenting a certificate that does not list
download.java.net as a SAN. Therefore with host verification, the build
can not use this site. This commit switches to using download.oracle.com
which appears to be an alternative name for the same CNAME
download.oracle.com.edgekey.net. This allows our builds to resume.
A stuck peer recovery in #40913 reveals that we indefinitely retry on
new cluster states if indexing translog operations hits a mapper
exception. We should not wait and retry if the mapping on the target is
as recent as the mapping that the primary used to index the replaying
operations.

After changing the allowed minimum value for min_children in has_child query from 0 to 1 in
the next major version, this PR adds a deprecation warning for these cases.
Closes#41548
This commit refactors GeoHashUtils class into a new Geohash utility class located in the ES geo library. The intent is to not only better control what geo methods are whitelisted for painless scripting but to clean up the geo utility API in general.
* Clarify that peer recovery settings apply to shard relocation
* Fix awkward wording of 1st sentence
* [DOCS] Remove snapshot recovery reference.
Call out link to [[cat-recovery]].
Separate expert settings.
Motivated by slow snapshot deletes reported in e.g. #39656 and the fact that these likely are a contributing factor to repositories accumulating stale files over time when deletes fail to finish in time and are interrupted before they can complete.
* Makes snapshot deletion async and parallelizes some steps of the delete process that can be safely run concurrently via the snapshot thread poll
* I did not take the biggest potential speedup step here and parallelize the shard file deletion because that's probably better handled by moving to bulk deletes where possible (and can still be parallelized via the snapshot pool where it isn't). Also, I wanted to keep the size of the PR manageable.
* See https://github.com/elastic/elasticsearch/pull/39656#issuecomment-470492106
* Also, as a side effect this gives the `SnapshotResiliencyTests` a little more coverage for master failover scenarios (since parallel access to a blob store repository during deletes is now possible since a delete isn't a single task anymore).
* By adding a `ThreadPool` reference to the repository this also lays the groundwork to parallelizing shard snapshot uploads to improve the situation reported in #39657
* Thanks to #39793 dynamic mapping updates don't contain blocking operations anymore so we don't have to manually put the mapping in this test and can keep it a little simpler
The subfields of the search_as_you_type are prefixed with the name of their root field.
However they should used the full path of the root field rather than just the name since
these fields can appear in a multi-`fields` definition or under an object field.
Since this field type is not released yet, this should be considered as a non-issue.
* Add Restore Operation to SnapshotResiliencyTests
* Expand the successful snapshot test case to also include restoring the snapshop
* Add indexing of documents as well to be able to meaningfully verify the restore
* This is part of the larger effort to test eventually consistent blob stores in #39504
Added integrations for a couple of frameworks.
Removed community clients where the last commit was more than three
years ago. Also added the official go client link and removed the
official groovy client, as it is outdated.
Under random seed 4304ED44CB755610 the generated byte pattern causes
BC-FIPS to throw
java.io.IOException: DER length more than 4 bytes: 101
Rather than simply returning an empty list (as it does for most random
values).
Backport of: #40939
Thanks to #34071, there is enough information in field caps to infer
the table structure and thus use the same API consistently across the
IndexResolver.

TLS 1.3 changes to the SSLEngine introduced a scenario where a UNWRAP
call during a handshake can consume a close notify alerty without
throwing an exception. This means that we continue down a codepath where
we assert that we are still in handshaking mode. Transitioning to closed
from handshaking is a valid scenario. This commit removes this
assertion.
