Before deleting a repository index generation file, BlobStoreRepository
checks for the existence of the file and then deletes it. We can save
a request here by using BlobContainer.deleteBlobIgnoringIfNotExists()
which ignores error when deleting a file that does not exist.
Since there is no way with S3 to know if a non versioned file existed
before being deleted, this pull request also changes S3BlobContainer so
that it now implements deleteBlobIgnoringIfNotExists(). It will now save
one more request (blobExist?) when appropriate. The tests and fixture
have been modified to conform the S3 API that always returns a 204/NO
CONTENT HTTP response on deletions.
This commit removes some tests in the repository-s3 plugin that
have not been executed for 2+ years but have been maintained
for nothing. Most of the tests in AbstractAwsTestCase were
obsolete or superseded by fixture based integration tests.
This pull request merges the AzureStorageService interface and
the AzureStorageServiceImpl classes into one single
AzureStorageService class. It also removes some tests in the
repository-azure plugin that have not been executed for 2+ years.
The current AzureStorageServiceImpl always checks if the Azure container
exists before reading or writing an object to the Azure container. This commit
removes this behavior, reducing the number of overhall requests executed
for all snapshots operations.
The interface and its implementation can be merged into a single class,
which is renamed to S3Service like the other S3BlobStore, S3Repository
classes.
* remove left-over comment
* make sure of the property for plugins
* skip installing modules if these exist in the distribution
* Log the distrbution being ran
* Don't allow running with integ-tests-zip passed externally
* top level x-pack/qa can't run with oss distro
* Add support for matching objects in lists
Makes it possible to have a key that points to a list and assert that a
certain object is present in the list. All keys have to be present and
values have to match. The objects in the source list may have additional
fields.
example:
```
match: { 'nodes.$master.plugins': { name: ingest-attachment } }
```
* Update plugin and module tests to work with other distributions
Some of the tests expected that the integration tests will always be ran
with the `integ-test-zip` distribution so that there will be no other
plugins loaded.
With this change, we check for the presence of the plugin without
assuming exclusivity.
* Allow modules to run on other distros as well
To match the behavior of tets.distributions
* Add and use a new `contains` assertion
Replaces the previus changes that caused `match` to do a partial match.
* Implement PR review comments
Introduces support for multiple host providers, which allows the settings based hosts resolver to be
treated just as any other UnicastHostsProvider. Also introduces the notion of a HostsResolver so
that plugins such as FileBasedDiscovery do not need to create their own thread pool for resolving
hosts, making it easier to add new similar kind of plugins.
With #20695 we removed local transport and there is just TransportAddress now. The
UnicastHostsProvider currently returns DiscoveryNode instances, where, during pinging, we're
actually only making use of the TransportAddress to establish a first connection to the possible new
node. To simplify the interface, we can just return a list of transport addresses instead, which
means that it's not necessary anymore to create fake node objects in each plugin just to return the
address information.
Currently we set local addresses on the creation time of a NioChannel.
However, this may return null as the local address may not have been
set yet. An example is the local address has not been set on a client
channel as the connection process is not yet complete.
This PR modifies the getter to set the local field if it is currently null.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
Adds the ability to reread and decrypt the local node keystore.
Commonly, the contents of the keystore, backing the `SecureSettings`,
are not retrievable except during node initialization. This changes that
by adding a new API which broadcasts a password to every node. The
password is used to decrypt the local keystore and use it to populate
a `Settings` object that is passes to all the plugins implementing the
`ReloadablePlugin` interface. The plugin is then responsible to do
whatever "reload" means in his case. When the `reload`handler returns,
the keystore is closed and its contents are no longer retrievable.
Password is never stored persistently on any node.
Plugins that have been moded in this commit are: `repository-azure`,
`repository-s3`, `repository-gcs` and `discovery-ec2`.
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
This commit adds a new QA sub project to the discovery-ec2 plugin.
This project uses a fixture to test the plugin using a multi-node cluster.
Once all nodes are started, the nodes transport addresses are written
in a file that is later read by the fixture.
Currently we maintain a compatibility map of http status codes in both
the netty4 and nio modules. These maps convert a RestStatus to a netty
HttpResponseStatus. However, as these fundamentally represent integers,
we can just use the netty valueOf method to convert a RestStatus to a
HttpResponseStatus.
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.
Many fixtures have similar code for writing the pid & ports files or
for handling HTTP requests. This commit adds an AbstractHttpFixture
class in the test framework that can be extended for specific testing purposes.
Currently the http pipelining handlers seem to support chunked http
content. However, this does not make sense. There is a content
aggregator in the pipeline before the pipelining handler. This means the
pipelining handler should only see full http messages. Additionally, the
request handler immediately after the pipelining handler only supports
full messages.
This commit modifies both nio and netty4 pipelining handlers to assert
that an inbound message is a full http message. Additionally it removes
the tests for chunked content.
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.
There's no need for an extra blobExists() call when writing a blob to the Azure service. Azure
provides an option (with stronger consistency guarantees) on the upload method that guarantees
that the blob that's uploaded does not already exist. This saves one network roundtrip.
Relates to #19749
Most of our license file names strip the version off the artifact name
when deducing the license filename. However, the version on the GCS SDK
(google-api-services-storage) does not match the usual format and
instead starts with a vee. This means that the license filename for this
license ended up carrying the version and we should not do that. This
commit adjusts the regex the deduces the license filename to account for
this case, and adjusts the google-api-services-storage license files
accordingly.
This is related to #27260 and #28898. This commit adds the transport-nio
plugin as a random option when running the http smoke tests. As part of
this PR, I identified an issue where cors support was not properly
enabled causing these tests to fail when using transport-nio. This
commit also fixes that issue.
This is related to #28898. This commit adds the acceptor thread name to
the method checking if this thread is a transport thread. Additionally,
it modifies the nio http transport to use the same worker name as the
netty4 http server transport.
This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
In #19749 an extra check was added before writing each blob to ensure that we would not be
overriding an existing blob. Due to S3's weak consistency model, this check was best effort. To
make matters worse, however, this resulted in a HEAD request to be done before every PUT, in
particular also when PUTTING a new object. The approach taken in #19749 worsened our
consistency guarantees for follow-up snapshot actions, as it made it less likely for new files that
had been written to be available for reads.
This commit therefore removes this extra check. Due to the weak consistency model, this check
was a best effort thing anyway, and there's currently no way to prevent accidental overrides on S3.
This is related to #28898. This commit adds cors support to the nio http
transport. Most of the work is copied directly from the netty module
implementation. Additionally, this commit adds tests for the nio http
channel.
This snapshot includes:
- LUCENE-8341: Record soft deletes in SegmentCommitInfo which will resolve#30851
- LUCENE-8335: Enforce soft-deletes field up-front
This is related to #31017. That issue identified that these three http
methods were treated like GET requests. This commit adds them to
RestRequest. This means that these methods will be handled properly and
generate 405s.
Currently AbstractHttpServerTransport is in a netty4 module. This is the
incorrect location. This commit moves it out of netty4 module.
Additionally, it moves unit tests that test AbstractHttpServerTransport
logic to server.
This commit removes some log traces in AzureStorageServiceImpl and also
fixes the AzureStorageServiceTests so that is uses the real
implementation to create Azure clients.
Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps
the CompletableFuture but does not accept Throwable. This allows the
modification of netty and nio logic to no longer handle Throwable.
This commit reintroduces 31251c9 and 63a5799. These commits introduced a
memory leak and were reverted. This commit brings those commits back
and fixes the memory leak by removing unnecessary retain method calls.
This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should
resolves failed tests in the CorruptedFileIT suite.
Closes#30741Closes#30577
This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
Added dedicated script contexts for:
* script function score
* script sorting
* terms_set query
Scripts for these contexts will either have a specific return value or
use scoring and therefor in the future will need their own scripting classes.

Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
There's no need for an extra blobExists() call when writing a blob to the GCS service. GCS provides

This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
This does away with the deprecated `com.google.api-client:google-api-client:1.23`
and replaces it with `com.google.cloud:google-cloud-storage:1.28.0`.
It also changes security permissions for the repository-gcs plugin.
HDFS sets its thread-name format based partly on a URL-encoded version of the
path, but the URL-encoding of spaces as `%20` is interpreted as a field in the
formatted string of type `2`, which is nonsensical. This change simply skips
these tests in this case.
There's no need for an extra `blobExists()` call when writing a blob to the HDFS service. The writeBlob implementation for the HDFS repository already uses the `CreateFlag.CREATE` option on the file creation, which ensures that the blob that's uploaded does not already exist. This saves one network roundtrip.
This change adds a new plugin called `analysis-nori` that exposes
Korean text analysis in es using the new Lucene Korean analyzer module named (`nori`).
The plugin adds:
* a Korean analyzer: `nori`
* a Korean tokenizer: `nori_tokenizer`
* a part of speech stop filter: `nori_part_of_speech`
* a filter that can replace Hanja characters with their Hangul transcription: `nori_readingform`
Upgrade to lucene-7.4.0-snapshot-1ed95c097b
This version contains:
* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.
* A new API to retrieve matches (offsets and positions) of a query for a single document.
* Support for soft deletes in the index writer.
* A fixed shingle filter that handles index time synonyms.
* Support for emoji sequence in ICUTokenizer (with an upgrade to icu 61.1)
Similarly to what has been done in for the repository-s3 plugin, this
pull request moves the fixture test into a dedicated
repository-azure/qa/microsoft-azure-storage project.
It also exposes some environment variables which allows to execute the
integration tests against the real Azure Storage service. When the
environment variables are not defined, the integration tests are
executed using the fixture added in #29347.

This *mostly* silences `javadoc`'s warning about defaulting to
generating html4 files by enabling generating html5 file for the
projects for which that works. It didn't work in a half dozen projects,
about half of which I've fixed in this PR, entirely by replacing
`<tt>thing</tt>` with `{@code thing}`.
There are a few remaining projects that contain javadoc with invalid
html5. I'll fix those projects in a followup.
This commit moves the repository-s3 fixture test added in #29296 in a
new `repository-s3/qa/amazon-s3` project. This new project allows the
REST integration tests to be executed using the real S3 service when
all the required environment variables are provided. When no env var
is provided, then the tests are executed using the fixture added
in #29296.
The REST tests located at the `repository-s3`plugin project now only
verify that the plugin is correctly loaded.
The REST tests have been adapted to allow a bucket name and a base
path to be specified as env vars. This way it is possible to run the tests
with different base paths (could be anything, like a CI job name or a
branch name) without multiplicating buckets.

This commit moves the apache and elastic license files into a new
root level `licenses` directory and rewrites the top level LICENSE.txt
to clarify the repository has a mix of apache and elastic licensed code.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
This commit introduces built in support for adding files to the
keystore when configuring the integration test cluster for a project.
In order to use this support, simply add `keystoreFile` followed by the
secure setting name and the path to the source file inside the
integTestCluster closure for a project. The built in support will
handle the creation of the keystore and the addition of the file to the
keystore.
Some features have been deprecated since `6.0` like the `_parent` field or the
ability to have multiple types per index. This allows to remove quite some
code, which in-turn will hopefully make it easier to proceed with the removal
of types.
* Move Streams.copy into elasticsearch-core and make a multi-release jar
This moves the method `Streams.copy(InputStream in, OutputStream out)` into the
`elasticsearch-core` project (inside the `o.e.core.internal.io` package). It
also makes this class into a multi-release class where the Java 9 equivalent
uses `InputStream#transferTo`.
This is a followup from
https://github.com/elastic/elasticsearch/pull/29300#discussion_r178147495
This commit adds a new fixture that emulates an
Azure Storage service in order to improve the
existing integration tests. This is very similar
to what has been made for Google Cloud Storage
in #28788 and for Amazon S3 in #29296, and it
would have helped a lot to catch bugs like #22534.
The repository-gcs unit tests rely on the GoogleCloudStorageTestServer
but it would be better if they rely on a mocked Storage client instead.
That would also help to extract the GoogleCloudStorageFixture and the
GoogleCloudStorageTestServer classes in a QA third party project.
Closes#28960
This commit adds the S3BlobStoreRepositoryTests class that extends the
base testing class for S3. It also removes some usage of socket servers
that emulate socket connections in unit tests. It was added to trigger
security exceptions, but this won't be needed anymore since #29296
is merged.
Today when you input a byte size setting that is out of bounds for the
setting, you get an error message that indicates the maximum value of
the setting. The problem is that because we use ByteSize#toString, we
end up with a representation of the value that does not really tell you
what the bound is. For example, if the bound is 2^31 - 1 bytes, the
output would be 1.9gb which does not really tell you want the limit as
there are many byte size values that we format to the same 1.9gb with
ByteSize#toString. We have a method ByteSize#getStringRep that uses the
input units to the value as the output units for the string
representation, so we end up with no loss if we use this to report the
bound. This commit does this.
This commit adds a new fixture that emulates a S3 service in order to
improve the existing integration tests. This is very similar to what has
been made for Google Cloud Storage in #28788, and such tests would
have helped a lot to catch bugs like #22534.
The AmazonS3Fixture is brittle and only implements the very necessary
stuff for the S3 repository to work, but at least it works and can be
adapted for specific tests needs.
Some source files seem to have the execute bit (a+x) set, which doesn't
really seem to hurt but is a bit odd. This change removes those, making
the permissions similar to other source files in the repository.
* Decouple XContentBuilder from BytesReference
This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.
While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).
Relates to #28504
We today support a global `indexed_chars` processor parameter. But in some cases, users would like to set this limit depending on the document itself.
It used to be supported in mapper-attachments plugin by extracting the limit value from a meta field in the document sent to indexation process.
We add an option which reads this limit value from the document itself
by adding a setting named `indexed_chars_field`.
Which allows running:
```
PUT _ingest/pipeline/attachment
{
"description" : "Extract attachment information. Used to parse pdf and office files",
"processors" : [
{
"attachment" : {
"field" : "data",
"indexed_chars_field" : "size"
}
}
]
}
```
Then index either:
```
PUT index/doc/1?pipeline=attachment
{
"data": "BASE64"
}
```
Which will use the default value (or the one defined by `indexed_chars`)
Or
```
PUT index/doc/2?pipeline=attachment
{
"data": "BASE64",
"size": 1000
}
```
Closes#28942
As we have factored Elasticsearch into smaller libraries, we have ended
up in a situation that some of the dependencies of Elasticsearch are not
available to code that depends on these smaller libraries but not server
Elasticsearch. This is a good thing, this was one of the goals of
separating Elasticsearch into smaller libraries, to shed some of the
dependencies from other components of the system. However, this now
means that simple utility methods from Lucene that we rely on are no
longer available everywhere. This commit copies IOUtils (with some small
formatting changes for our codebase) into the fold so that other
components of the system can rely on these methods where they no longer
depend on Lucene.
With this commit we skip all GeoIpProcessorFactoryTests on Windows.
These tests use a MappedByteBuffer which will keep its file mappings
until it is garbage-collected. As a consequence, the corresponding
file appears to be still in use, Windows cannot delete it and the test
will fail in teardown.
Closes#29001
Windows has some strong limitations on command line arguments,
specially when it's too long. In the googlecloudstoragefixture anttask
the classpath argument is very long and the command fails. This commit
removes the classpath as an argument and uses the CLASSPATH
environment variable instead.
With this commit we reduce heap usage of the ingest-geoip plugin by
memory-mapping the database files. Previously, we have stored these
files gzip-compressed but this has resulted that data are loaded on the
heap.

This commit adds a GoogleCloudStorageFixture that uses the
logic of a GoogleCloudStorageTestServer (added in #28576)
to emulate a remote Google Cloud Storage service.
By adding this fixture and a more complete integration test, we
should be able to catch more bugs when upgrading the client library.
The fixture is started by the googleCloudStorageFixture task
and a custom Service Account file is created and added to the
Elasticsearch keystore for each test.
This is related to #27260. The transport-nio plugin needs socket
permissions to operate as a transport. This commit gives it these
permissions in the policy file.
This commit is related to #27260. Currently there is a weird
relationship between channel contexts and nio channels. The selectors
use the context for read and writing. But the selector operates directly
on the nio channel for registering, closing, and connecting.
This commit works on improving this relationship. The selector operates
directly on the context which wraps the low level java.nio.channels. The
NioChannel class is simply an API that is used to interact with the
channel (sending messages from outside the selector event loop,
scheduling a close, adding listeners, etc). The context is only used
internally by the channel to implement these apis and by the selector to
perform these operations.
Similarly to what has been done for s3 and azure, this commit removes
the repository settings `application_name` and `connect/read_timeout`
in favor of client settings. It introduce a GoogleCloudStorageClientSettings
class (similar to S3ClientSettings) and a bunch of unit tests for that,
it aligns the documentation to be more coherent with the S3 one, it
documents the connect/read timeouts that were not documented at all and
also adds a new client setting that allows to define a custom endpoint.
This is related to #28662. It wraps the azure repository inputstream in
an inputstream that ensures `read` calls have socket permissions. This
is because the azure inputstream internally makes service calls.
This pull request extracts in a dedicated class the request/response
logic that "emulates" a Google Cloud Storage service in our
repository-gcs tests.
The idea behind this is to make the logic more reusable. The class
MockHttpTransport has been renamed to MockStorage which now
only takes care of instantiating a Storage client and does the low-level
request/response plumbing needed by this client.
The "Google Cloud Storage" logic has been extracted from
MockHttpTransport and put in a new GoogleCloudStorageTestServer
that is now independent from the google client testing framework.
