MetaDataSerivce tried to protect concurrent index creation/deletion
from resulting in inconsistent indices. This was originally added a
long time ago via #1296 which seems to be caused by several problems
that we fixed already in 2.0 or even in late 1.x version. Indices where
recreated without being deleted and shards where deleted while being used
which is now prevented on several levels. We can safely remove the semaphores
since we are already serializing the events on the cluster state threads.
This commit also fixes some expception handling bugs exposed by the added test
We currently have two, which is confusing when you read the code (especially if one is used with a null default and the other with '*')
Note: this is not a real bug, just a clean up. We do the right thing...
Closes#13988
After a full cluster restart, the elected master is tasked with recovery the last known cluster state from disk. To do so, the GatewayService registers it self as a listener to cluster state changes, triggering the recovery if the local node is elected. Sadly the initial post-election cluster state can be missed if it's being processed while the listener is registered (i.e., the listener is too late but the discoveryService.initialStateReceived is not yet set). In this case the cluster state from disk will be recovered with the next change (typically node join).
In practice this is not a big deal as master election takes at least 3s (by which time the gateway is long started), but it does make some of our tests to fail: http://build-us-00.elastic.co/job/es_core_master_centos/7915/
To fix this, we submit a cluster state task after the edition of the listener, so we are guaranteed to check things while they are at rest.
While at it, I removed some left over latch which we don't really wait on anymore.
Closes#13997
When we check the engine if a flush is needed we don't catch EngineClosedException today
but the engine is potentially closed already in which case we can simply return false and don't need
to bubble up the exception.
Closed indices are currently out of scope for snapshots and shard migration,
and can cause issues in managed environments – where closing an index does
not necessarily make sense, as it still consumes the managed environment's storage quota.
This commit adds an option to dynamically disable closing indices via node or cluster settings.
Closes#14168
We used to change the minimumShouldMatch field of the query depending on the context, the final minimim should match should still be applied based on that, but the original minimumShouldMatch of the query shouldn't change. This was revelead by some recent test failure.
Closes#14153
Currently we require parser to be right before the sources START_OBJECT
but if we are parsing embedded search sources this won't work since we potentially
moved already on to the START_OBJECT. This commit make this optional such that
both ways work.
We can't track disk usage in this situation, failing is the correct thing to do.
But we can give a FreeBSD-specific error message, so the user can set the
necessary jail parameters, versus a vague IOException.

Test that the lucene "unmap hack" is supported.
We should know if this is not working for any configuration, otherwise resources such as address space, file handles, and even disk space become tied to Java's garbage collector.
This test failed only on a feature branch, because that feature branch has
a different build randomization script and is the only place
randomizing tests.security.manager (this test cannot run with it enabled).
On old kernels without TSYNC support, the test fails because (surprise to me) the thread that
runs the test is not the same thread that runs static initializers:
7571489190/randomized-runner/src/main/java/com/carrotsearch/randomizedtesting/RandomizedRunner.java (L573-L574)
To fix this test (its not an issue in practice, since we do this before creating threadpools),
we just record for testing purposes that we couldn't TSYNC, and re-run the whole thing for the test thread
in setUp(), failing if something goes wrong.
Also add a bunch of additional paranoia and narrow our defensive checks better here after reading
through more chrome bug reports: they don't impact us but those linux distros are too cowboy
with the backports and the spirit of the checks makes me feel better.
This commit adds a new metric aggregator for computing the geo_centroid over a set of geo_point fields. This can be combined with other aggregators (e.g., geohash_grid, significant_terms) for computing the geospatial centroid based on the document sets from other aggregation results.
This commit cleans up IndexMetaData. In particular, all duplicate
getters (X and getX) have been collapsed into one (getX). Further, the
number of shards and number of replicas settings are now parsed once
and saved off as fields.
* Add ability for plugins to declare additional permissions with a custom plugin-security.policy file and corresponding AccessController logic. See the plugin author's guide for more information.
* Add warning messages to users for extra plugin permissions in bin/plugin.
* When bin/plugin is run interactively (stdin is a controlling terminal and -b/--batch not supplied), require user confirmation.
* Improve unit test and IDE support for plugins with additional permissions by exposing plugin's metadata as a maven test resource.

Decentralize plugin permissions (modulo docs and pluginmanager work)
This commit makes sure that the plugin script looks at user, group and permissions of the elasticsearch bin dir and copies them over to the plugin bin subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed. We also make sure that execute permissions are added for files (we already did this before).

Today we leak an index searcher if we fail to wrap the seacher in
IndexShard. This commit ensures that the seacher is released if the wrapper
throws an exception.
This commit also restructures some test to be more atomic and only test a single
feature / attribute of the wrapper.
This commit changes the behavior of Cache#computeIfAbsent to not invoke
load for a key under the segment lock. Instead, the synchronization
mechanism to ensure that load is invoked at most once per key is
through the use of a future. Under the segment lock, we put a future in
the cache and through this ensure that load is invoked at most once per
key. This will not lead to the same deadlock situation as before
because a dependent key load on the same thread can not be triggered
while the segment lock is held.
Closes#14090
We randomly use the WindowsFS mock file system to simulate that
windows does not delete files if they are opened by some other
process and instead gives you java.io.IOException: access denied.
In the tests we also check if the shard was deleted while it is
being deleted. This check loads the mata data of the index
and therefore might hold on to a file while the node
is trying to delete it and deletion will fail then.
Instead we should just check if the directory was removed.
closes#13758
this commit also fixes a bug where we wramed a leaf reader in a top level context
which caused atomic segment readers to be used in our top level caches.
IndexReader#addReaderCloseListener is very error prone when it comes to
caching and reader wrapping. The listeners are not delegated to the sub readers
nor can it's implementation change since it's final in the base class. This commit
only allows installing close listeners on the top level ElasticsearchDirecotryReader
which is known to work an has a defined lifetime which corresponds to its subreader.
This ensure that cachesa re cleared once the reader goes out of scope.
In #13606, the ability to exclude a template from being wiped was added but a call to
wipeTemplates() was not removed, so all index templates were still being removed.
This change removes the wipeTemplates() call in the wipe method so that only the
non-excluded templates are removed.
Depending on how elasticsearch is installed, we have two scenarios to take into account that relate to user, group and permissions assigned to the config directory:
1) deb/rpm package: /etc/elasticsearch is root:elasticsearch 750 and the plugin script is run from root user
2) tar/zip archive: es config dir is most likely elasticsearch:elasticsearch and the plugin script is most likely run from elasticsearch user
When the plugin script copies over the plugin config dir within the es config dir, it should take care of setting the proper user, group and permissions, which vary depending on how elasticsearch was installed in the first place. Should be root:elasticsearch 750 if installed from a package, or elasticsearch:elasticsearch if installed from an archive.
This commit makes sure that the plugin script looks at user, group and permissions of the config dir and copies them over to the plugin config subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed in the first place. We also make sure that execute permissions are left untouched for files.

make the version map cache per-segment
This commit adds methods to serialize the elements of int and long
arrays using variable-length encodings. This can be useful for
serializing int and long arrays containing mostly non-negative “not
large” values in a compressed form.
FiltersFunctionScoreQuery sums up scores and weights and scores as double but when
we explain we cannot get the double scores from the explanation of score
functions. as a result we cannot compute the exact score from the explanations
of the functions alone.
this commit makes the explanation more accurate but also causes the score to be
computed one additional time.
we should sum the weights as double to not lose precision. also,
the tests should simulate exactly what function score does and then test
for equality of scores.
This method is unused can can simply be removed. It's rather confusing
instead since it's another way of invalidating a cache entry but not through
the close listener.
Restoring an index from a snapshot or creating a new index can bring the index settings index.blocks.read_only, index.blocks.read, index.blocks.write and index.blocks.metadata out-of-sync with the corresponding cluster blocks.
Closes#13931
The IndexAliasesService abstraction only adds unnecessary code and classes
and can be removed. This commit folds the rather simple methods in this
class into IndexService where the IndexAliasesService was obtained from in the past.
RoutingTable.Builder#build can only be called once but didn't have any
checks to make sure it _was_ only called once. And the error message it
threw when called more than once was a NullPointerException. This makes
it throw IllegalStateException when you try to reuse the builder in any way.
- removes Lucene.count(IndexSearcher,Query) in favor of IndexSearcher.count(Query)
- removes EarlyTerminatingCollector.reset(): reusing Collector objects does not
help given that query execution needs to allocate objects (weights, scorers)
anyway
- adds unit tests to Lucene.exists
When deleting an individual scroll ID, ES does produce a 200 in the
header if successful and a 404 if the scroll ID wasn't found, but
returns empty response body. It will be more user friendly to provide
some information on whether the scroll deletion is successful.
This commit removes all index level compatibilty and upgrade paths for
pre 2.0 indices. This includes:
* Remove leftover from delete_by_query to replay translog records,
since in 3.x all pending delelte_by_query instances are applied on the
upgrade to 2.x we can remove the bwc layer now.
* Remove Elasticsearch090PostingsFormat - we maintained our own posting format
until 2.0 this is now removed since folks need to upgrade to 2.x first before going
to 3.0
* Remove BloomFilterPostingFormat - this was only used for ID fields in the Elasticsearch090PostingsFormat
* Remove upgrade methods to pre 2.0 translogs without checkpoints
In #13971, the RenderSearchTemplateAction was made a cluster level action but the client methods
were not moved from the IndicesAdminClient. This is an inconsistency and this change cleans up the
inconsistency so that the client methods are now part of the ClusterAdminClient since the action is now
considered a cluster level action.
This test had to be moved to lang-groovy when groovy has been made a plugin.
I refactored it a bit to use mock plugins instead so that groovy is not
necessary anymore and it can come back to core.
The RenderSearchTemplateAction is currently a "indices" action, but the action does not really apply to
indices, it is more of a general action that is used to validate the search template. With our current
categorization of actions, `cluster:` and `indices:`, `cluster:` is a more appropriate type as this action
is not associated with indices. The classes are also moved to a cluster package.
GeoPoint now has native support in StreamOutput/StreamInput
impementing Writable is not necessary. This also adds tests
for XContentBuilder rendering GeoPoint
This fixes license checks to apply to all java files under src/ as opposed to
only those in the org.elasticsearch package. It found some license headers that
had to be reformatted. I also added a missing license header to Nullability.java
however this has not be caught by the license checker since it ignores guice
files.
