This commit adds support for an info() method to the High Level Rest
client that returns the cluster information usually obtained by performing a
`GET hostname:9200` request.
Console.readText may return null in certain cases. This commit fixes a
bug in Terminal.promptYesNo which assumed a non-null return value. It
also adds a test for this, and modifies mock terminal to be able to
handle null input values.
This commit fixes the reproduce line output when the vagrant packagingTest
fails. Before only the `gradle packagingTest` would be output, but the
seed and list of versions was swallowed by groovy with an ancillary
failure (due to the `+` being on the wrong line for a string
continuation). With the new reproduce line, it is now output next to
the task right after failure, contains the actual task (specific to the
box that fails), and contains the seed. It also no longer contains the
upgrade versions list, as the seed is used to determine which of those
to use, and the same file would be read when testing a failure on a
particular git commit. Finally, this also ties bats test setup directly
to packagingTest, instead of to the vagrant up command.
The dependencyLicenses check has the ability to map multiple jar files
to the same license file. However, netty was not taking advantage of
this, and had duplicate copies of its license/notice files for each jar.
This commit reduces the copies to one and uses the mapping feature.
This commit removes an necessary test that ensures if
wait_for_active_shards cannot be fulfilled on index creation, that the
response returns shardsAcknowledged=false. However, this is already
tested in WaitForActiveShardsIT and it would improve the speed of the
test runs to get rid of any unnecessary tests, especially those that
depend on timeouts.
The IndexShardOperationsLock has a mechanism to delay operations if there is currently a block on the lock. These
delayed operations are executed when the block is released and are executed by a different thread. When the different
thread executes the operations, the ThreadContext is that of the thread that was blocking operations. In order to
preserve the ThreadContext, we need to store it and wrap the listener when the operation is delayed.
The REST Client is split into 2 parts:
* Low level
* High level
The High level client has a main common section and the document delete API documentation as a start.
NamedXContentRegistry will be used by the high level REST client to parse aggregation responses, and any section whose class type depends on a json key. There are currently on entries in the standard registry, but soon aggs and most likely suggesters will be added. Also it is possible for subclasses to provide additional named xcontent parsers.
Load the geoip database the first time a pipeline gets created that has a geoip processor.
This saves memory (measured ~150MB for the city db) in cases when the plugin is installed, but not used.
This change exposes the new Lucene graph based word delimiter token filter in the analysis filters.
Unlike the `word_delimiter` this token filter named `word_delimiter_graph` correctly handles multi terms expansion at query time.
Closes#23104
This is fallout from #23297. That commit wrapped
`InstanceProfileCredentialsProvider` to ensure that the `getCredentials`
and `refresh` methods had privileged access. However, it looks like
there was a test ensuring that `buildCredentials` returned the correct
clazz type. This commit adjusts that test to check that the correct
wrapper is returned.
This commit adds a boundary_scanner property to the search highlight
request so the user can specify different boundary scanners:
* `chars` (default, current behavior)
* `word` Use a WordBreakIterator
* `sentence` Use a SentenceBreakIterator
This commit also adds "boundary_scanner_locale" to define which locale
should be used when scanning the text.
There are two ways to determine the latest index-N blob that contains
the truth of the contents of the repository: (1) list all index-N blobs
and figure out what the latest value of N is, and (2) read the
index.latest blob, which contains the latest value of N explicitely.
Note that the index.latest blob is not written atomically and can be
re-written, as opposed to the index-N blobs which are never re-written
(to create an updated index blob, index-{N+1} is written).
Previously, the latest index-N was determined by first trying to read
the index.latest blob and if that blob was missing (it was deleted
before being re-written and in between deleting it and re-writing it,
the system crashed), then all index-N blobs were listed to pick the
highest N value.
For non-read-only repositories, this could produce race conditions with
the file system. In particular, it is possible that the index.latest
blob is being read in order to serve a read request (e.g. get snapshots)
and while doing so, an attempt is made to delete the index.latest blob
and re-write it in order to finalize a snapshot operation. On some file
systems (e.g. Windows), it is forbidden to delete a file while it is
open for reading by another process/thread.
This commit changes the priority so that figuring out the latest index-N
blob is first done by listing all index-N blobs and determining the
latest N value. If that values because the repository does not
support listing blobs (e.g. the URL repository), then the index.latest
blob is read. This is safe because in read-only repositories that do
not support listing blobs, the index.latest blob is never deleted and
then re-written, so the aforementioned issue does not arise.
The test setup for hdfs is a little complicated for windows, needing to
check if the hdfs fixture can be run at all. This was unfortunately not
updated when the integ tests were reorganized into separate runner and
cluster setups.
This commit sets the intial size of the pipeline handler queue small to
prevent waste if pipelined requests are never sent. Since the queue will
grow quickly if pipeline requests are indeed set, this should not be
problematic.

This commit fixes an issue that was missed in #22534.
`AWSCredentialsProvider.getCredentials()` appears to potentially open a
socket connect. This operation needed to be wrapped in `doPrivileged()`.
This should fix issue #23271.
When pipelined responses are sent to the pipeline handler for writing,
they are not necessarily written immediately. They must be held in a
priority queue until all responses preceding the given response are
written. This means that when write is invoked on the handler, the
promise that is attached to the write invocation will not necessarily be
the promise associated with the responses that are written while the
queue is drained. To address this, the promise associated with a
pipelined response must be held with the response and then used when the
channel context is actually written to. This was introduced when
ensuring that the releasing promise is always chained through on write
calls lest the releasing promise never be invoked. This leads to many
failing test cases, so no new test cases are needed here.

Previous changes aligned HEAD requests to be consistent with GET
requests to the same endpoint. This commit aligns the REST spec for the
impacted endpoints.

In oder to use lucene's utilities to merge top docs the results
need to be passed in a dense array where the index corresponds to the shard index in
the result list. Yet, we were sorting results before merging them just to order them
in the incoming order again for the above mentioned reason. This change removes the
obsolet sort and prevents unnecessary materializing of results.
When a rest integ test has multiple nodes, each node is supposed to not
start configuring itself until the first node has been started, so that
the unicast host information can be written. However, this was never
explicitly setup to occur, and we were just very lucky with the current
gradle version and stability of the code always produced a task graph
that had node0 starting first. With the recent refactorings to integ
tests, the order has changed. This commit fixes the ordering by adding
an explicit dependency between the first node and the other nodes.
This commit moves the LICENSE.txt and NOTICE.txt files for each plugin
to be alongside the other plugin files, inside the elasticsearch subdir.
This ensures those files are installed alongside the plugin.
In update scripts, `ctx._now` uses the same milliseconds value used by the
rest of the system to calculate deltas. However, that time is not
actually epoch milliseconds, as it is derived from `System.nanoTime()`.
This change reworks the estimated time thread in ThreadPool which this
time is based on to make available both the relative time, as well as
absolute milliseconds (epoch) which may be used with calendar system. It
also renames the EstimatedTimeThread to a more apt CachedTimeThread.

Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
From #23093, we fixed the issue where a filesystem can be so large that it
overflows and returns a negative number. However, there is another issue when
adding a path as a sub-path to another `FsInfo.Path` object, when adding the
totals the values can still overflow.
This adds the same safety to return `Long.MAX_VALUE` instead of the negative
number, as well as a test exercising the logic.
When a node wants to join a cluster, it sends a join request to the master. The master then sends a join validation request to the node. This checks that the node can deserialize the current cluster state that exists on the master and that it can thus handle all the indices that are currently in the cluster (see #21830).
The current code can trip an assertion as it does not take the cluster state as is but sets itself as the local node on the cluster state. This can result in an inconsistent DiscoveryNodes object as the local node is not yet part of the cluster state and a node with same id but different address can still exist in the cluster state. Also another node with the same address but different id can exist in the cluster state if multiple nodes are run on the same machine and ports have been swapped after node crashes/restarts.
When sending a response to a client, we attach a releasing listener to
the channel promise. If the client disappears before the response is
sent, the releasing listener was never notified. The reason the
listeners were never notified was due to a mistaken invocation of write
and flush on the channel which has two overrides: one that takes an
existing promise, and one that does not and instead creates a new
promise. When the client disappears, it is this latter promise that is
notified, which does not contain the releasing listener. This commit
addreses this issue by invoking the override that passes our channel
promise through.
