There is a bug in the error message that is thrown if the number of docs differs between the source and target shards when recovering a shard with a syncId. The source and target doc counts are swapped around.
Closes#21893
Currently, such tasks are only created for default boxes (centos-7, ubuntu-1404) and not all boxes and this can be misleading for developers who want to debug testing scripts on non-default boxes.
Removes `AggregatorParsers`, replacing all of its functionality with
`XContentParser#namedObject`.
This is the third bit of payoff from #22003, one less thing to pass
around the entire application.
If the remote doesn't return a content type then reindex
tried to guess the content-type. This didn't work most
of the time and produced a rather useless error message.
Given that Elasticsearch always returns the content-type
we are dropping content-type detection in favor of just
failing the request if the remote didn't return a content-type.
Closes#22329
The test ping and waited for the ping results to be returned but since we first return the result and then close temporary connections, assertions are tripped that expects all connections to close by end of test .
Closes#22497
This commit checks for a null BytesReference as the value for `source`
in GetResult#sourceRef and simply returns null. Previously this would
have resulted in a NPE. While this does seem internal at first glance, it can affect
user code as a GetResponse could trigger this when the document is missing.
Additionally, the CompressorFactory#uncompressIfNeeded now requires a
non-null argument.
This patch fixes the incorrect indentation in the REST tests, which makes tests in language runners (eg. Ruby, Python) to fail, since the skip clause is parsed as an empty value. Tha Java YAML parser is smarter/lenient about whitespace, so it doesn't catch this.
The recovery process started during primary relocation of shadow replicas accesses the engine on the source shard after it's been closed, which results in the source shard failing itself.
Right now closing a shard looks like it strands refresh listeners,
causing tests like
`delete/50_refresh/refresh=wait_for waits until changes are visible in search`
to fail. Here is a build that fails:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+multi_cluster_search+multijob-darwin-compatibility/4/console
This attempts to fix the problem by implements `Closeable` on
`RefreshListeners` and rejecting listeners when closed. More importantly
the act of closing the instance flushes all pending listeners
so we shouldn't have any stranded listeners on close.
Because it was needed for testing, this also adds the number of
pending listeners to the `CommonStats` object and all API to which
that flows: `_cat/nodes`, `_cat/indices`, `_cat/shards`, and
`_nodes/stats`.
In pre 2.x versions, if the repository was set to compress snapshots,
then snapshots would be compressed with the LZF algorithm. In 5.x,
Elasticsearch no longer supports the LZF compression algorithm. This
presents an issue when retrieving snapshots in a repository or upgrading
repository data to the 5.x version, because Elasticsearch throws an
exception when it tries to read the snapshot metadata because it was
compressed using LZF.
This commit gracefully handles the situation by introducing a new
incompatible-snapshots blob to the repository. For any pre-2.x snapshot
that cannot be read, that snapshot is removed from the list of active
snapshots, because the snapshot could not be restored anyway. Instead,
the snapshot is recorded in the incompatible-snapshots blob. When
listing snapshots, both active snapshots and incompatible snapshots will
be listed, with incompatible snapshots showing a `INCOMPATIBLE` state.
Any attempt to restore an incompatible snapshot will result in an
exception.
`ToXContentObject` extends `ToXContent` without adding new methods to it, while allowing to mark classes that output complete xcontent objects to distinguish them from classes that require starting and ending an anonymous object externally.
Ideally ToXContent would be renamed to ToXContentFragment, but that would be a huge change in our codebase, hence we simply document the fact that toXContent outputs fragments with no guarantees that the output is valid per se without an external ancestor.

This is related to #22116. A logIfNecessary() call makes a call to
NetworkInterface.getInterfaceAddresses() requiring SocketPermission
connect privileges. By moving this to bootstrap the logging call can be
made before installing the SecurityManager.
1. Escape sequences we're working. For example `\\` is now correctly
interpreted as `\` instead of `\\`. Same with `\'` being `'` and
`\"` being `"`.
2. `'` delimited strings weren't allowed to contain `"`s but it looked
like they were intended to support it. Now they do.
3. Improves the error message when the script contains an invalid
escape sequence inside a string to include a list of the valid
escape sequences.
Closes#22372
The JDK 9 compiler (b151) emits the warning "No processor claimed any of these annotations" for annotations that would be runtime annotation. Maybe a
regression from https://bugs.openjdk.java.net/browse/JDK-8039469. This is a quick fix so that compilation works again.
Today when an index is shrunk the version information is not carried over
from the source to the target index. This can cause major issues like mapping
incompatibilities for instance if an index from a previous major version is shrunk.
This commit ensures that all version information from the soruce index is preserved
when a shrunk index is created.
