The query cache is disabled on dfs_query_then_fetch so we need to enforce
query_then_fetch instead of relying on the randomized search type set by the
test framework.
This commit brings the benefits of the `count` search type to search requests
that have a `size` of 0:
- a single round-trip to shards (no fetch phase)
- ability to use the query cache
Since `count` now provides no benefits over `query_then_fetch`, it has been
deprecated.

Even if there is a background thread that periodically closes search contexts
that seem unused (every minute by default), it is important to close search
contexts as soon as possible in order to not keep unnecessary open files or
to prevent segments from being deleted.
This check would help ensure that refactorings of the SearchContext management
like #9296 are correct.
FakeRestRequest is used by a few tests and can also be leveraged by
tests outside of elasticsearch. Moving the package will mean the class
gets exported as part of the test jar.
We already force a refresh in index/create ops, to clear version map
when it's using too much RAM, but we were failing to do this for
deletes, so an app that does tons of deletes with no indexing, and has
set refresh_interval to -1, would have version map using unbounded
RAM.

When the index service (which holds shards) fails to be created as a result of a shard being allocated on a node, we should fail the relevant shard, otherwise, it will remain stuck.
Same goes when there is a failure to process updated mappings form the master.
Note, both failures typically happen when the node is misconfigured (i.e. missing plugins, ...), since they get created and processed on the master node before being published.

Doc values significantly reduced heap usage, which results in faster
GCs. This change makes the default for doc values dynamic: any

The local DocumentMapper is updated while parsing and dynamic fields are added before
parsing has finished. If parsing fails after a dynamic field has been added already
then the field was not added to the cluster state but was present in the local mapper of this
node. New documents with the same field would not necessarily cause an update either and
after restarting the node the mapping for these fields were lost. Instead the new fields
should always be updated.

We currently have a single bw comp test (FunctionScoreBackwardCompatibilityTests) that requires inline scripts on.
After introducing fine-grained script settings, we moved the internal cluster to use the newer settings, but they are not supported by older nodes started as part of the bw comp tests. Moved script settings out of the default settings, so they won't be part of the ordinary settings when running bw comp tests.
Added logic in FunctionScoreBackwardCompatibilityTests to enable dynamic scripts using the proper setting, depending on the version of the node.
Allow to on/off scripting based on their source (where they get loaded from), the operation that executes them and their language.
The settings cover the following combinations:
- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping
The following settings are supported for every engine:
script.engine.groovy.indexed.update: sandbox/on/off
script.engine.groovy.indexed.search: sandbox/on/off
script.engine.groovy.indexed.aggs: sandbox/on/off
script.engine.groovy.indexed.mapping: sandbox/on/off
script.engine.groovy.dynamic.update: sandbox/on/off
script.engine.groovy.dynamic.search: sandbox/on/off
script.engine.groovy.dynamic.aggs: sandbox/on/off
script.engine.groovy.dynamic.mapping: sandbox/on/off
script.engine.groovy.file.update: sandbox/on/off
script.engine.groovy.file.search: sandbox/on/off
script.engine.groovy.file.aggs: sandbox/on/off
script.engine.groovy.file.mapping: sandbox/on/off
For ease of use, the following more generic settings are supported too:
script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file: sandbox/on/off
script.update: sandbox/on/off
script.search: sandbox/on/off
script.aggs: sandbox/on/off
script.mapping: sandbox/on/off
These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.
Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.
Also, the previous `script.disable_dynamic` setting can now be deprecated.

In #9893, an enabled flag was added for _field_names. However,

Deleting a type from an index is inherently dangerous because
the type can be recreated with new mappings which may conflict

If a request comes in at the same moment the timeout handler for it runs, we may leak a timeoutInfoHolder and erroneously log "Transport response handler not found of id" . The same issue could cause the request tracer to fire a traceUnresolvedResponse call instead of traceReceivedResponse , causing a failure of testTracerLog ( see #10187 ) .
This commit makes sure timeoutInfoHolder is visible before removing the corresponding RequestHolder. It also unifies the TransportService.Adapter#remove(requestId) with TransportService.Adapter#onResponseReceived(requestId), as they are always called together to indicate a response was received.

When a primary moves to another node, we cancel ongoing recoveries and retry from the primary's new home. At the moment this happens when the primary relocation *starts*. It's a shame as we cancel recoveries that may be close to completion and will finish before the primary has been fully relocated. This commit only triggers the cancelation once the primary relocation is completed.
Next to this, it fixes a race condition between recovery cancellation and the recovery completion. At the moment we may trigger remove a recovered shard just after it was completed. Instead, we should use the recovery cancellation logic to make sure only one code path is followed.
All of the above caused the recoverWhileUnderLoadWithNodeShutdown test to fail (see http://build-us-00.elastic.co/job/es_core_15_debian/32/ ). The test creates an index and then increasingly disallows nodes for it, until only 1 node is left in the allocation filtering rules. Normally, this means we stay in green, but the premature recovery cancellation plus the race condition mentioned above caused a shard to be failed and stay unassigned and the test asserts to fail. This happens due to the following sequence:
- The shard has finished recovering and sent the master a shard started command.
- The recovery is cancelled locally, removing the index shard.
- Master starts shard (deleting it's other copy).
- Local node gets a cluster state with the shard started in it, which cause it to send a shard failed (to make the master aware).
- Shard is failed and can't be re-assigned due to the allocation filter.
The recoverWhileUnderLoadWithNodeShutdown is also adapted a bit to fit the current behavior of allocation filtering (in the past it used to really shut down nodes). Last, all tests in that class are given better names to fit the current terminology.

Sometimes, when using transport client for example, through a load balancer, there is a need to send a scheduled ping message to keep each channel alive.
Add support for `transport.ping_schedule`, which controls the schedule (-1 for disabled) at which a ping message will be sent. For transport client case, it gets enabled automatically since almost always this is the desired behavior.
We use the same 6 bytes header format for the ping message, with ES header and -1 for data length for ping message, and simply continue to process the next messages once this is encountered.

This commit changes the behaviour of the delete api when processing a delete request that refers to a type that has routing set to required in the mapping, and the routing is missing in the request. Up until now the delete api sent a broadcast delete request to all of the shards that belong to the index, making sure that the document could be found although the routing value wasn't specified. This was probably not the best choice: if the routing is set to required, an error should be thrown instead.
A `RoutingMissingException` gets now thrown instead, like it happens in the same situation with every other api (index, update, get etc.). Last but not least, this change allows to get rid of a couple of `TransportAction`s, `Request`s and `Response`s and simplify the codebase.

This makes the assertion a bit more flexible and removes the

This commit allows code to be executed before or after a shards content

Fixing geo_shape field mapper to persist the orientation parameter. Also adding parsing and integration tests to ensure persistence across cluster restarts.
Adds a setting to disable detailed error messages and full exception stack traces
in HTTP responses. When set to false, the error_trace request parameter will result
in a HTTP 400 response. When the error_trace parameter is not present, the message
of the first ElasticsearchException will be output and no nested exception messages
will be output.
In case an exception was caught by the repeat rule, the retry mechanism would kick in only if the exception was the expected one. If not an NPE got thrown, while we should rather just bubble it up to the caller. This makes `NettyTransportMultiPortTests` run from a plane. An assumption would kick in to make sure that the test gets ignored but the `AssumptionViolationException` was caught and not properly re-thrown.
In case a HTTP client connects to the transport protocol and issues a
HTTP method followed by a space, we can just try to be smart and return
a string back to the client to point the user to the fact that the wrong
port has been used.

To support real time gets, the engine keeps an in-memory map of recently index docs and their location in the translog. This is needed until documents become visible in Lucene. With 1.3.0, we have improved this map and made tightly integrated with refresh cycles in Lucene in order to keep the memory signature to a bare minimum. On top of that, if the version map grows above a 25% of the index buffer size, we proactively refresh in order to be able to trim the version map back to 0 (see #6363) . In the same release, we have fixed an issue where an update to the indexing buffer could result in an unwanted exception during recovery (#6667) . We solved this by waiting with updating the size of the index buffer until the shard was fully recovered. Sadly this two together can have a negative impact on the speed of translog recovery.
During the second phase of recovery we replay all operations that happened on the shard during the first phase of copying files. In parallel we start indexing new documents into the new created shard. At some point (phase 3 in the recovery), the translog replay starts to send operation which have already been indexed into the shard. The version map is crucial in being able to quickly detect this and skip the replayed operations, without hitting lucene. Sadly #6667 (only updating the index memory buffer once shard is started) means that a shard is using the default 64MB for it's index buffer, and thus only 16MB (25%) for the version map. This much less then the default index buffer size 10% of machine memory (shared between shards).
Since we don't flush anymore when updating the memory buffer, we can remove #6667 and update recovering shards as well. Also, we make the version map max size configurable, with the same default of 25% of the current index buffer.

The file scripts cache key should include the language of the script to prevent conflicts between scripts with same name but different extension (hence lang). Note that script engines can register multiple acronyms that may be used as lang at execution time (e.g. javascript and js are synonyms). We then need to make sure that the same script gets loaded no matter which of the acronyms is used at execution time. The problem didn't exist before this change ad the lang was simply ignored, while now we take it into account.
This change has also some positive effect on inline scripts caching. Up until now, the same script referred to with different acronyms would be compiled and cached multiple times, once per acronym. After this change every script gets compiled and cached only once, as we chose internally the acronym used as part of the cache key, no matter which one the user provides.

The tribe node, at startup, sets up the tribe clients that will join their corresponding tribes. All of the tribe.* settings are properly forwarded to the corresponding tribe client. System properties and global configuration settings must not be forwarded to the tribe client though or they will end up overriding per tribe settings with same name causing issues.
For instance if you set the transport.tcp.port to some defined value for the tribe node, via system property or configuration file, that same value must not be forwarded to the tribe clients, otherwise they will try and use the same port, which will be already occupied by the tribe node itself, resulting in startup failed. Same for cluster.name, which will cause the tribe clients not to join their tribes.

We've been relying on URI for url encoding, but it turns out it has some problems. For instance '+' stays as is while it should be encoded to `%2B`. If we go and manually encode query params we have to be careful though not to run into double encoding ('+'=>'%2B'=>'%252B'). The applied solution relies on URI encoding for the url path, but manual url encoding for the query parameters. We prevent URI from double encoding query params by using its single argument constructor that leaves everything as is.
We can also revert back the expression script REST test that revealed this to its original content (which contains an addition).

It may take some time for the old master node to step down anf for it to rejoin and that all nodes have it in the nodes list.
By waiting for the old master node to have stepped down, we can again rely on assertDiscoveryCompleted() to make sure that it has joined.
If the isolated unicast host is also a master node then its local cluster state gets unusable a source for pinging when the disruption stops.
All the nodes in the cluster state node list can be removed and at that time it will only ping itself and never find out about the other nodes.

CurrentTestFailedMarker is a RunListener that gets notified whenever a test fails, and we were using it to be able to restart the suite cluster after each failure. We were checking whether a test had failed in the @After method though, which runs before the listener gets notified, so the failed flag would always be false.
This commit makes sure that the suite cluster gets restarted not only when there are problems in the afterInternal method, but also after each test failure. In order to achieve this, we need to reset the cluster afterwards, when we get to know about both of the events (problem in afterInternal and test failure), and before resetting the currentCluster. Introduced a TestRule that keeps track of test failures and allows to execute arbitrary tasks when a test fails and when a test is completed (regardless of its result). Allows also to force the execution of the failure task (used in case of afterInternal issues rather than actual test failure).
Also updated ElasticsearchRestTests to make sure that the RestClient gets re-initialized in case we restart the suite cluster, otherwise all the subsequent tests fail. Improved this mechanism also to relate it directly to the restart of the cluster instead of checking whether the addresses have changed, which doesn't work anyway as the new cluster will use the same addresses but the client needs to be recreated anyway.

We keep track of the current stage of recovery using an instance of RecoveryState which is stored on the relevant IndexShard. At the moment changes to this object are made in many places of the code, which are charged of doing it in the right order, keeping track of timers and many more. Also the changes to shard state are decoupled from the recovery stages which caused #9503.
This PR refactors this and brings all of the changes into IndexShard. It also makes all recovery follow the exact same stages and shortcut some. This is in order to keep things simple and always the same (those shortcuts didn't add anything, we ended doing it all anyway).
Also, all timer management is now folded into RecoveryState and unit tests are added.
This closes#9503 by moving the shard to post recovery only once the recovery is done (before they were decoupled), meaning that master promotion of the target shard to started can not cancel the recovery.

cutover apis, no work on test failures yet.
Some tests failures are seen when a node attempts to use a port that is already bound
by some other process on the test machine. This commit adds a bind to test port availability
and iterates over the port range until an available port is found. This reduces the likelihood
of a test node failing to start up due to the port already being bound.
Today we have two ways of getting a setting, either with the full settings key or with only
the last part of the key where the prefix is implicit depending on the package the class is in via
component settings. this is trappy as well as confusing for users and can break easily if a class is moved
to a new package since the prefix then implicitly changes.
This commit removes the component settings from the codebase.
Almost all of our meta fields that allow enabling/disabling have an `enabled`
setting. However, _field_names is enabled by default, and disabling
requires setting `index=no`. This change adds a flag similar to that

To support the `_recovery` API, the recovery process keeps track of current progress in a class called RecoveryState. This class currently have some issues, mostly around concurrency (see #6644 ). This PR cleans it up as well as other issues around it:
- Make the Index subsection API cleaner:
- remove redundant information - all calculation is done based on the underlying file map
- clearer definition of what is what: total files, vs reused files (local files that match the source) vs recovered files (copied over). % based progress is reported based on recovered files only.
- cleaned up json response to match other API (sadly this breaks the structure). We now properly report human values for dates and other units.
- Add more robust unit testing
- Detail flag was passed along as state (it's now a ToXContent param)
- State lookup during reporting is now always done via the IndexShard , no more fall backs to many other classes.
- Cleanup APIs around time and move the little computations to the state class as opposed to doing them out of the API
I also improved error messages out of the REST testing infra for things I run into.

Today we fail the shard if we need to upgrade a replica to a primary on shadow replicas
on shared filesystem. Yet, this commit allows promotion by re-initializing on the master preventing
reallocation of all replicas.
We try to lock all shards when an index is deleted but likely not
succeeding since shards are still active. To ensure that shards
that used to be allocated on that node get cleaned up as well we have
to retry or block on the delete until we get the locks. This is not desirable
since the delete happens on the cluster state processing thread. Instead of blocking
this commit schedules a pending delete for the index just like if we can't delete shards.
There are two implications to this change.
First, percolator now uses _uid internally, extracting the id portion
when needed. Second, sorting on _id is no longer possible, since you
can no longer index _id. However, _uid can still be used to sort, and
is better anyways as indexing _id just to make it available to
fielddata for sorting is wasteful.
see #8143closes#9842
Today if we delete files from the index directory we never acquire the
write lock. Yet, for safety reasons we should get the write lock before
we modify / delete any files. Where we can we should leave the deletion
to the index writer and only delete that are necessary to delete ourself.
Refactor how settings filters are handled. Instead of specifying settings filters as filtering class, settings filters are now specified as list of settings that needs to be filtered out. Regex syntax is supported. This is breaking change and will require small change in plugins that are using settingsFilters. This change is needed in order to simplify cluster state diff implementation.

However, the change was never added to the cluster state.
This commit makes sure mapping updates are always added to the cluster state
even if indexing of a document fails.
closes#8692
relates to #8650
Now that the global cluster is gone, we shoudln't need to ignore
thread leaks across tests. We unfortunately still need suite level
scope, since most tests are using suite scope clusters (although
test clope clusters should really switch back to test scope thread
leaks).
closes#9843
These help a lot when refactoring, upgrading lucene, etc, and
can prevent code duplication (as you get a compile error for outdated stuff).
Closes#9832.
This change removes the deprecated script parameter names ('file', 'id', and 'scriptField').
It also removes the ability to load file scripts using the 'script' parameter. File scripts should be loaded using the 'script_file' parameter only.
If an elected master node goes into a long gc then other nodes' fault detection will notice this and a new master election is started and eventually a new master node is elected. If the previous master nodes goes out of the long gc it can still have pending tasks which can result in new cluster state updates. Nodes that are still in the nodes list of this previous elected master node can get these cluster state updates. This commit makes sure that this dated cluster states are not accepted by these nodes.
This issue can temporary lead to the fact that non elected master nodes switch to the previous elected master node. The new elected master node also gets the same dated cluster state, but rejects it and tells the previous elected master node to step down and rejoin. Because the new elected master is the only master node the previous elected master node will follow the new elected master node. Any nodes that follow the previous elected master node (by accident), will also rejoin and follow the new elected master node because their master fault detection will fail. So all in all this isn't a severe problem, because the problem fixes itself eventually.
Closes#9632
Currently many meta field mappers do not take index settings in their
simple constructor that DocumentMapper uses, and instead pass null or
empty settings to the parent abstract mapper. This change fixes them to
pass through index settings, and adds an assertion in AbstractFieldMapper
that settings are not null.
closes#9780
This was previously attempted in #8854. I revived that branch and did
some performance testing as was suggested in the comments there.
I fixed all the errors, mostly just the rest tests, which
needed to have http enabled on the node settings (the global cluster
previously had this always enabled). I also addressed the comments from
that issue.
My performance tests involved running the entire test suite on my
desktop which has 6 cores, 16GB of ram, and nothing else was being
run on the box at the time. I ran each set of settings 3 times and
took the average time.
| mode | master | patch | diff |
| ------- | ------ | ----- | ---- |
| local | 409s | 417s | +2% |
| network | 368s | 380s | +3% |
This increase in average time is clearly worthwhile to pay to achieve
isolation of tests. One caveat is the way I fixed the rest tests
is still to have one cluster for the entire suite, so all the rest
tests can still potentially affect each other, but this is an
issue for another day.
There were some oddities that I noticed while running these tests
that I would like to point out, as they probably deserve some
investigation (but orthogonal to this PR):
* The total test run times are highly variable (more than a minute between the min and max)
* Running in network mode is on average actually *faster* than local mode. How is this possible!?
Today locking all shards only locks the shards that are present on
the node or that still have a shard directory. This can lead to odd
behavior if another shard that doesn't exist yet is allocated while
all shards are supposed to be locked.
Adds RandomShapeGenerator for creating random shape types. This adds a level of randomized testing to the Geospatial logic. An initial randomized GeometryCollection test is added to the GeoShapeIntegrationTest suite for validating and verifying geo_shape filter behavior. The RandomShapeGenerator can/should be used in Unit and Integration testing to avoid biased testing.

upgrade to lucene_r1660560, modulo one test fail
Today if a shard deletion fails we simply ignore it and move on. On system like
windows where a virus scanner can hold on to files or any other process ie. the admins
explorer window we fail to delete shards leaving large amout of data behind. We should try
best effort to clean those shards up before we ack the delete.
Today we restore files by running through the directory removeing all files
not in the snapshot. Some files in that direcotry might belong there even though
we remove them. This commit moves the responsiblity of cleaning up pending files
to lucene by utilizing IndexWriter#IndexFileDeleter
This commit makes the `postings_format` and `doc_values_format` options of
mappings illegal on 2.0 and ignored on 1.x (meaning that the default postings
and doc values formats from the codec will be used in such a case).
This removes a fair amount of code.

Add ShadowEngine
Change bucket key_as_string to reflect `time_zone` parameter. Currently `time_zone`
shifts bucket boundaries to other time zone, but keys are displayed in UTC, so e.g.
daily buckets in "+01:00" time zone have key_as_string like "2014-01-01T23:00:00Z". With this
change the default is to format this dates according to the local time zone, so the
above bucket key would be "2014-01-02T00:00:00+01:00".

Today we trash everything that has been indexed but not flushed to disk
if the engine is closed. This might not be desired if we shutting down a
node for restart / upgrade or if we close / archive an index. In such a
case we would like to flush the transaction log and commit everything to
disk. This commit adds a flag to the close method that is set on close
and shutdown but not when we remove the shard due to relocations
The nested scope is set by any nested feature, so that sub nested queries and filters know about their context and these sub nested queries and filters can construct the right parent filter.
Removed the LateBindingParentFilter workaround in the nested query parser in favour of the nested scope maintained in the query parse context.
Due to this change nested queries and filters can now also be included in nested sorting and inner hits, because those features also now use the nested scope.
This change doesn't fix the usage of nested filters in nested and reverse_nested aggregations. The `nested` filter shouldn't be used inside these aggregations and instead the `nested` and `reverse_nested` aggs should be used to query on the right level. In a different change `nested` inside a `nested` and `reverse_nested` aggregation should result in a parse error.
Closes#9305
Removed the existing `pre_zone` and `post_zone` option in `date_histogram` in favor of
the simpler `time_zone` option. Previously, specifying different values for these could
lead to confusing scenarios where ES would return bucket keys that are not UTC.
Now `time_zone` is the only option setting, the calculation of date buckets to take place in the
preferred time zone, but after rounding converting the bucket key values back to UTC.
Closes#9062Closes#9637
When asking for term statistics, generating term vectors on the fly or with
`dfs` set to `true`, some requests may take a while, so it is useful to know
exactly how long.
Closes#9583
Negative settings for interval in date_histogram could lead to OOM errors in conjunction
with min_doc_count=0. This fix raises exceptions in the histogram builder and the
TimeZoneRounding classes so that the query fails before this can happen.
Closes#9634Closes#9690
Today we sometimes have to transfer files without verifying the checksum
ie. if the file had an old alder32 checksum but was using random access
while writing such that we can only verify they files length. We will likely
not detect corruptions there and with the new checks during recovery finalization
we might run into corrupt index exceptions in that stage. This causes
the primary to be failed as well since we don't handle the exception today. This commit
adds better handling and a test for this scenario.
Groovy was disabled by default, but we turn it on in our test infra. We can then declare support for it so we go and execute script related tests as part of the REST tests suite.
With #9629 we introduced REST spec validation, which barfs whenever the REST spec don't follow the defined conventions. That said, we sometimes execute tests against previous branches and tags which have spec that needs fixing but we can't go back and fix them. We now support the `-Dtests.rest.validate_spec` system property that allows to turn off REST spec validation (enabled by default) so that we can still run tests against old branches/tags.
When multiple fields under object fields share the same name, accessing
by short name is ambiguous. This removes support for short names,
always requiring the full name when used in queries.
closes#8872
This moves the rule, so it is made available in the test.jar. In
addition, you can now specify the exception, which triggers a rerun
of the test in order to make it reusable for others.
Also ensured that the NettyTransportTest frees all resources inside
of its testing method instead of pre/post running methods, as those
are still called only once, even though a failed test might be repeated.
Using '_cat/segments' or the indices segments api without matching any index
now returns empty result instead of throwing IndexMissingException.
Closes#9219
Aggregators now return a new collector instance per segment, like Lucene 5 does
with its oal.search.Collector API. This is important for us because things like
knowing whether the field is single or multi-valued is only known at a segment
level.
In order to do that I had to change aggregators to notify their sub aggregators
of new incoming segments (pretty much in the spirit of #6477) while everything
used to be centralized in the AggregationContext class. While this might slow
down a bit deeply nested aggregation trees, this also makes the children
aggregation and the `breadth_first` collection mode much better options since
they can now only replay what they need while they used to have to replay the
whole aggregation tree.
I also took advantage of this big refactoring to remove some abstractions that
were not really required like ValuesSource.MetaData or BucketAnalysisCollector.
I also splitted Aggregator into Aggregator and AggregatorBase in order to
separate the Aggregator API from implementation helpers.
Close#9544
Whenever we have an api that supports GET with a body, we always support the POST method too, as well as providing the body as a query_string parameter called `source`. Our REST spec should reflect this convention. FIxed them and introduced a hard check at parse time in our Java REST tests runner, which will cause the tests to fail if spec are not compliant.
Closes#9629
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.
closes#9638
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`.
_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.
closes#6730
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.
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.

upgrade to lucene r1657571
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
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.
This commit removes the FlushType entirely and replaces it in the most places with
a simple `Engine#flush()` call. Flushing without committing the translog is now
entirely private to the engine and is only called in one place.
The `full` option and `FlushType.NEW_WRITER` only exists to allow
realtime changes to two settings (`index.codec` and `index.concurrency`).
Those settings are very expert and don't really need to be updateable
in realtime.
When the master publishes a new cluster state it waits (by default) for up to 30s for all nodes to respond. If not it continues to process other pending tasks. At the moment, this timeout is logged under DEBUG but it typically represent a serious issue with one or more of the nodes. We should log it in WARN and give the nodes that failed to respond in a timefly fashion
Closes#9551
We currently have the IndicesRequest interface to mark indices related requests and be able to retrieve the indices they relate to in a generic way. This commit introduces a similar abstraction for requests that manage aliases, to be able to retrieve/replace the aliases they relate to.
Also, IndicesAliasesRequest becomes a CompositeIndicesRequest, as it allows to perform multiple operations (e.g. add/remote multiple aliases). Each single operation (AliasActions) implements now the newly introduced AliasesRequest.
AliasesRequest is also implemented by GetAliasesRequest, which allows to retrieve aliases information.
Closes#9460
In big deployment ClusterState can be large. To make sure we keep reusing objects that were promoted to the Old Gen, ZenDiscovery has an optimization where it tries to reuse existing IndexMetaData object (containing among other things the mappings) from the current cluster state if they didn't change. The comparison currently uses the index name and the metadata version. This is however not enough and we should also check the index uuid. In extreme cases, where cluster state processing is slow and the index in question is deleted and recreated and these operations are batch processed together, we can use the wrong meta data if the version is also identical. This can happen if people create the index with all meta data predefined and no settings were changed.
Closes#9489Closes#9541
When closing an instance of RestClient, the connection manager gets shutdown, which makes it not usable anymore. If that is static, like it is now, no RestClient will work anymore from that moment on. Each instance of RestClient should have its own instance of connection manager
This method is heavy as it builds a bitset out of a DocIdSet in order to be
able to provide random-access. Now that Lucene has removed out-of-order scoring
true random-access is very rarely needed and we could instead return an Bits
instance that wraps the iterator. Ideally, we would use the DISI API directly
but I have to admit that the Bits API is more friendly.
Close#9546
We had a REST test that relied on matching a json response against a regex. It worked but the match wasn't done against the actual json object, but its java map representation converted into a string by calling `toString`. Since all other clients test runners don't work in this case, as they try to match a json object against a regex, we should do the same and prevent it from working.
The current "checkindex" on startup is very very expensive. This is
like running one of the old school hard drive diagnostic checkers and
usually not a good idea.
But we can do a CRC32 verification of files. We don't even need to
open an indexreader to do this, its much more lightweight.
This option (as well as the existing true/false) are randomized in
tests to find problems.
Also fix bug where use of the current option would always leak
an indexwriter lock.
Closes#9183
Histogram aggregation supports an 'offset' option to move bucket boundaries.
In a histogram with buckets of size X these can be moved from 0, X, 2X, 3X,...
by an offset value of Y to Y, X+Y, 2X+Y, 3X+Y... by using the 'offset' option.
The previous 'pre_offset' and 'post_offset' options are removed in favour of
the simplified 'offset' option.

Until now, there was no possibility to expose infos about configured
transport profiles. This commit adds the ability to expose those
information in the TransportInfo class.
The channel was well as the netty pipeline handler now also contain
the profile they were configured for, as this information cannot be
extracted elsewhere.
In addition, each profile now can set its own publish host and port,
which might be needed in case of portforwarding or using docker.
Closes#9134
This callback is executed only once, on the master node during an
index's creation. An exception thrown during this listener will cancel
the index creation.
This also adds checks in `IndicesClusterStateService` for the
indexService being null as well as if the `indicesService.createIndex`
throws an exception on data nodes after an index has already been
created.
#8720 introduced a timeout mechanism for ongoing recoveries, based on a last access time variable. In the many iterations on that PR the update of the access time was lost. This adds it back, including a test that should have been there in the first place.
Closes#9506
The query-cache has an optimization to not deserialize the bytes at the shard
level. However this is a bit fragile since it assumes that serialized streams
can be concatenanted (which is not the case with shared strings) and also does
not update the QueryResult object that is held by the SearchContext. So you
need to make sure to use the right one.
With this change, the query cache just deserializes bytes into the QueryResult
object from the context.
Close#9500
Due to some unreleased refactorings we lost the persitence of

provided in the search
Currently, doing a field lookup within a terms agg will restrict the
fields available to those within the types passed into the search
request. However, when doing sub aggs within a children agg, the
fields available should not be restricted to those of the search.
This change makes the field lookup use the index level mapper service.
The optimization we do in the HandlesStreamInput / Output
adds a lot of complexity with a rather unknown benefit. It tries
to compress commonly used strings and write ids instead. This
should rather be done on a lower level if at all necessary for
the small message we send over the network.
Today we have a dirty flag indicating that a refresh must
be executed. We also allow users to bypass this by setting
a force=true boolean on the refresh request / command. All
these flags are unneeded since the SearcherManager has all
the information to do the right thing if it's dirty or not.
This pr removes the optimization for auto generated ids.
Previously, when ids were auto generated by elasticsearch then there was no
check to see if a document with same id already existed and instead the new
document was only appended. However, due to lucene improvements this
optimization does not add much value. In addition, under rare circumstances it might
cause duplicate documents:
When an indexing request is retried (due to connect lost, node closed etc),
then a flag 'canHaveDuplicates' is set to true for the indexing request
that is send a second time. This was to make sure that even
when an indexing request for a document with autogenerated id comes in
we do not have to update unless this flag is set and instead only append.
However, it might happen that for a retry or for the replication the
indexing request that has the canHaveDuplicates set to true (the retried request) arrives
at the destination before the original request that does have it set false.
In this case both request add a document and we have a duplicated a document.
This commit adds a workaround: remove the optimization for auto
generated ids and always update the document.
The asumtion is that this will not slow down indexing more than 10 percent,
see: http://benchmarks.elasticsearch.org/closes#8788closes#9468
Additionally, this setting can be specified in elasticsearch.yml if
desired, to pre-populate the list of methods to be added to the default
blacklist.
When making a change to this setting dynamically, the entire blacklist
is logged as well.
The `analyzer` setting is now the base setting, and `search_analyzer`
is simply an override of the search time analyzer. When setting
`search_analyzer`, `analyzer` must be set.
closes#9371
Using the `script.groovy.sandbox.method_blacklist_patch` setting, the
blacklist can be dynamically *added* to by specifying a comma-separated
list of methods (for example, "toString,size" would add .toString and
.size to the blacklist).
When the `script.groovy.sandbox.method_blacklist_patch` setting is
changed, the script cache is cleared to force new scripts to be
recompiled. Additionally the on-disk cache is cleared so that scripts in
the `config/scripts` directory are re-compiled as well.
This also fixes an issue where script engines were injected more than
once, which can cause multiple instances of the script engine per node.
Extended_stats now displays the upper and lower bounds on standard deviations (e.g. avg +/- std).
Default is to show 2 std above/below, but can be changed using the `sigma` parameter.
Accepts non-negative doubles
Closes#9356
To properly replicate, we currently stop flushing during recovery so we can repay the translog once copying files are done. Once recovery is done, the translog will be flushed by a background thread that, by default, kicks in every 5s. In case of a recovery failure and a quick re-assignment of a new shard copy, we may fail to flush before starting a new recovery, causing it to deal with potentially even longer translog. This commit makes sure we flush immediately when the ongoing recovery count goes to 0.
I also added a simple recovery benchmark.

If an index is deleted during initial state of the snapshot operation, the entire snapshot can fail with NPE. This commit improves handling of this situation and allows snapshot to continue if partial snapshots are allowed.

PR #8672 addresses ambiguous polygons - those that either cross the dateline or span the map - by complying with the OGC standard right-hand rule. Since ```GeoPolygonFilter``` is self contained logic, the fix in #8672 did not address the issue for the ```GeoPolygonFilter```. This was identified in issue #5968
This fixes the ambiguous polygon issue in ```GeoPolygonFilter``` by moving the dateline crossing code from ```ShapeBuilder``` to ```GeoUtils``` and reusing the logic inside the ```pointInPolygon``` method. Unit tests are added to ensure support for coordinates specified in either standard lat/lon or great-circle coordinate systems.

The InternalClusterInfoService reaches out to the nodes to get information about their disk usage and shard store size. Upon a node level error we currently remove the node info from the local cache. We should also clear the cache when we run into an error on the action level (excluding any info from all nodes).
This also adds settings for the timeout used when waiting for nodes.
Closes#9449
This change makes the response API object for Histogram Aggregations the same for all types of Histogram, and does the same for all types of Ranges.
The change removes getBucketByKey() from all aggregations except filters and terms. It also reduces the methods on the Bucket class to just getKey() and getKeyAsString().
The getKey() method returns Object and the actual Type is returns will be appropriate for the type of aggregation being run. e.g. date_histogram will return a DateTime for this method and Histogram will return a Number.
Apparently some filesystems such as ZFS and occasionally NTFS can report
filesystem usages that are negative, or above the maximum total size of
the filesystem. This relaxes the constraints on `DiskUsage` so that an
exception is not thrown.
If 0 is passed as the totalBytes, `.getFreeDiskAsPercentage()` will
always return 100.0% free (to ensure the disk threshold decider fails
open)

This bug was introduced by #8454 which allowed the childFilter to only be consumed once. By adding the child docid buffering multiple buckets can now be emitted by the same doc id. This child docid buffering only happens in the scope of the current root document, so the amount of child doc ids buffered is small.
