As a CliTool command could potentially also delete files, the
CheckFileCommand needs to check if those files exist, before
trying to get permissions/owners/groups from that path.
When using the CLI tool infrastructure, a command can potentially write
a new file. In case it overwrites an existing one, you may want to ensure
that the permissions, the owner and the group are kept the same and do not
accidentally change when overwriting those files.
This PR introduces a command that allows you to execute this check per path.
It also adds a new testing dependency, namely jimfs, which allows you to create
in-memory filesystems with certain properties (like supporting or not posix permissions
on this filesystem), so that you can test those features, without executing
tests on a certain operating system.
The FileSystemUtils class has a helper method to create files with
a .new suffix, in case the file, which should be created already
exists. If you install plugins and those have configuration files,
even without changes, you will end up with tons of .new files.
This commit checks the file size and sha-256 sum, and only if those
differ, a .new file is actually being created.
On CI machines node recovery sometimes takes up to 2 seconds. When it happens an update cluster state task gets stuck behind the recovery and tests fail with 1 second timeout. This commit makes sure that we wait for recovery to complete before starting the clock.
This has been very trappy. Rather than continue to allow buggy behavior
of having upgrade/optimize requests sidestep the single shard per node
limits optimize is supposed to be subject to, this removes
the ability to run the upgrade/optimize async.

Unfortunately the lock order is important in the current flush codehe. We have to acquire the readlock fist otherwise
if we are flushing at the end of the recovery while holding the write lock we can deadlock if:
* Thread 1: flushes via API and gets the flush lock but blocks on the readlock since Thread 2 has the writeLock
* Thread 2: flushes at the end of the recovery holding the writeLock and blocks on the flushLock owned by Thread 2
This commit acquires the read lock first which would be done further down anyway for the time of the flush.
As a sideeffect we can now safely flush on calling close() while holding the writeLock.
Today the logic related to deleting an index is spread across several
classes which makes changes to this rather delicate part of the code-base
very difficult. This commit consolidates this logic into the IndicesService
and moves the handling of ack-ing the delete to the master entirely into
`IndicesClusterStateService`.
The percolate api doesn't parse the encoded body provided as `source` query string parameter, when percolating an existing document. Fixed and added REST test that would have caught this since we randomly use GET + encoded `source` param instead of GET + request body in our java runner (the perl runner does the same too).
Closes#9628
_id and _routing now no longer support the 'path' setting on indexes
created with 2.0. Indexes created before 2.0 still support this
setting for backcompat.

Improve cleanup of updateTask timeout handlers. The timeout handlers should be removed as soon as a corresponding update task is processed. Otherwise, timeout handlers might keep old updateTasks and all objects that they are pointing to in memory for the duration of timeout (15 minutes by default).
Fixes#9621
The engine is already pretty complex, it's still confulated with
code that doesn't necessarily belong there. Updateing the settings from
the settings service can be done on the level above. This commit cleans up
the settings code in the engine and moves it to the IndexShard.
"The OpenGIS Abstract Specification: An Object Model for Interoperable Geoprocessing" published by the OGC defines "The boundary of a geometric object is a set of geometric objects of the next lower dimension." The bounding box of a GeometryCollection is therefore the set of bounding rectangles derived from the geometric objects of the next lower dimension. This commit updates the computeBoundingBox and relate methods for the ShapeCollection base class to correctly determine the prefixTree detail level used in Lucene's FilterCellIterator.

Until lately we couldn't close the engine in a tragic event due to
some the lock order and all it's complications. Now that the engine
is much more simplified in terms of having a single IndexWriter etc.
we don't necessarily need the write-lock on close anymore and can
easily just close and continue.
InternalEngine contains a number of inner classes that it uses, however,
this makes the class overly large and hard to extend. In order to be
able to easily add other Engines (such as the ShadowEngine), these
helping methods have been extracted into an AbstractEngine class. The
classes that were previously in `InternalEngine` have been moved to
separate classes, which will allow for better unit testing as well.
None of the functionality of InternalEngine has been changed, this is
only refactoring.
Note that this is a change I originally made on my shadow-replica
branch, however it is easier to review piecemeal so I extracted it into
a separate PR.
Sometimes by the time update settings is called the second node is not in the cluster yet. As a result change of minimum master node settings to 2 is ignored making this test to fail.
Add offset option to 'date_histogram' replacing and simplifying the previous 'pre_offset' and 'post_offset' options.
This change is part of a larger clean up task for `date_histogram` from issue #9062.
Due to the possibility of ports being already used when choosing a
random port, it makes sense to simply repeat a unit test upon a bind
exception.
This commit adds a junit rule, which does exactly this and does not
require you to change the test code and add loops.
Closes#9010
In the ShardRecoveryHandler we issue cluster update tasks to update the
mapping. The annonymous inner class backreferences the ShardRecoveryHandler
which holds a potentially large IndexShard object (which references buffers & caches etc)
If the queue of update tasks piles up and recoveries get cancled and/or shards are closed
the ShardRecoveryHandler can't be GCed. This commit moves the update task into a static
inner class to allos the GC to do its job.
Closes#9587

upgrade to lucene r1657571
Issue #9566 raises the point that setting the number of shards on a closed index can lead to this index not beeing able to open again. This change in documentation is ment to warn the user about this issue.
After phase1 of recovery is completed, we check that all pending mapping changes have been sent to the master and processed by the other nodes. This is needed in order to make sure that the target node has the latest mapping (we just copied over the corresponding lucene files). To make sure we do not miss updates, we do so under a local cluster state update task. At the moment we don't have a timeout when waiting on the task to be completed. If the local node update thread is very busy, this may stall the recovery for too long. This commit adds a timeout (equal to `indices.recovery.internal_action_timeout`) and upgrade the task urgency to `IMMEDIATE`. If we fail to perform the check, we fail the recovery.
Closes#9575
This commit adds more logs around the gateway shard allocation. Any errors while reaching out to nodes to list the local shards are logged in `WARN`. Shard info loading time is logged under DEBUG. Also, we log a `WARN` message if an exception forces a full checksum check during reading the store metadata
Closes#9562
We now have a very useful annotation to mark features or parameters as
experimental. Let's use it! This commit replaces some custom text warnings with
this annotation and adds this annotation to some existing features/parameters:
- inner_hits (unreleased yet)
- terminate_after (released in 1.4)
- per-bucket doc count errors in the terms agg (released in 1.4)
I also tagged with this annotation settings which should either be not needed
(like the ability to evict entries from the filter cache based on time) or that
are too deep into the way that Elasticsearch works like the Directory
implementation or merge settings.
Close#9563
These aggregations are not experimental anymore but some of their parameters
still are:
- `precision_threshold` and `rehash` on `cardinality`
- `compression` on percentiles(-ranks)
Close#9560
That method checks that files were release properly, but also clears a static map holding references to mock directories. Since we iterate on many indexes this created memory pressure.
