Lucene SuppressForbidden is marked lucene.internal and should not be
used outside of Lucene. This commit removes the uses of this class
within Elasticsearch. Instead,
org.elasticsearch.common.SuppressForbidden should be used, which was
already the case in most places.
Recent changes adds an extra bin/ directory that contains Windows bat files in the normal Bin folder of elasticsearch. For exemple the script elasticsearch.bat is located in bin/bin/elasticsearch.bat instead of bin/elasticsearch.bat.
Modifying the translog replay to not replay again into the translog
introduced a bug for the case of multiple operations for the same
doc. Namely, since we were no longer updating the version map for each
operation, the second operation for a doc would be treated as a creation
instead of as an update. This commit fixes this bug by placing these
operations into version map. This commit includes a failing test case.

Today we pull doc stats from an index reader which might not reflect reality.
IndexWriter might have merged all deletes away but due to a missing refresh
the stats are completely off. This change pulls doc stats from the IndexWriter
directly instead of relying on refreshes to run regularly. Note: Buffered deletes
are still not visible until the segments are flushed to disk.
If the relocation source fails during the relocation of a shard from one node to another, the
relocation target is currently failed as well. For replica shards this is not necessary,
however, as the actual shard recovery of the relocation target is done via the primary shard.
Our current testing for TimeUnitRoundings rounding() and nextRoundingValue()
methods that are used especially for date histograms lacked proper randomization
for time zones. We only did randomized tests for fixed offset time zones
(e.g. +01:00, -05:00) but didn't account for real world time zones with
DST transitions.
Adding those tests revealed a couple of problems with our current rounding logic.
In some cases, usually happening around those transitions, rounding a value down
could land on a value that itself is not a proper rounded value. Also sometimes
the nextRoundingValue would not line up properly with the rounded value of all
dates in the next unit interval.
This change improves the current rounding logic in TimeUnitRounding in two ways:
it makes sure that calling round(date) always returns a date that when rounded
again won't change (making round() idempotent) by handling special cases happening
during dst transitions by performing a second rounding. It also changes the
nextRoundingValue() method to itself rely on the round method to make sure we
always return rounded values for the unit interval boundaries.
Also adding tests for randomized TimeUnitRounding that assert important basic
properties the rounding values should have. For better understanding and readability
a few of the pathological edge cases are also added as a special test case.
Like on other places in the query dsl the full field name should be used.
Before this change this wasn't the case for nested inner hits when source filtering was used.
Highlighting has a workaround, which is now removed as the source of nested inner hits can only be refered by the full name.
Closes#16653
This change makes it possible to compile a separate project with e.g. targetCompatibility 1.7. Adds specific options (compact profile) only when compiling for >= 1.8.
It came out with improvements around idea integration and language levels. This will make it possible to have the upcoming java client as a new project compiled against java 7 and have idea working on the right language level.
When performing a local recovery, the engine replays operations
recovered from the translog into the translog again. These duplicated
operations are eventually cleared after successful recovery on flush,
but there is no need to play these operations into the translog at
all. This commit modifies the local recovery process so as to not replay
these operations into the translog.

This commit adds documentation for the bootstrap checks and provides
either links or inline guidance for setting the necessary settings to
pass the bootstrap checks.

This PR changes the InternalTestCluster to support dedicated master nodes. The creation of dedicated master nodes can be controlled using a new `supportsMasterNodes` parameter to the ClusterScope annotation. If set to true (the default), dedicated master nodes will randomly be used. If set to false, no master nodes will be created and data nodes will also be allowed to become masters. If active, test runs will either have 1 or 3 masternodes
This commit fixes an issue with the plugins directory being a symbolic
link. Namely, the install plugins command attempts to always create the
plugins directory just in case it does not exist. The JDK method used
here guarantees that the directory is created, and an exception is not
thrown if the directory could not be created because it already
exists. The problem is that this JDK method does not respect symlinks so
its internal existence checks fails, it proceeds to attempt to create
the directory, but the directory creation fails because the symlink
exists. This is documented as being not an issue. We work around this by
checking if there is a symlink where we expect the plugins directory to
be, and only attempt to create if not. We add a unit test that plugin
installation to a symlinked plugins directory works as expected.
When mocking unassigned shards which have failed with reason ALLOCATION_FAILED we
have to ensure that the failed allocation counter is strictly positive.
The distributions had their own copies of these extra files, which was a
carry over from maven. This change removes the duplicate files and
copies them from the root of the project.
closes#18597
It looks like the readme was duplicated when plugins were merged back
into the repo. We removed all these extra files from the plugins, this
removes the remaining duplicate from core.
closes#18597
This commit removes the ability to specify a custom plugins
path. Instead, the plugins path will always be a subdirectory called
"plugins" off of the home directory.
