In the past the Low Level REST Client was super careful not to wrap
any exceptions that it throws from synchronous calls so that callers can
catch the exceptions and work with them. The trouble with that is that
the exceptions are originally thrown on the async thread pool and then
transfered back into calling thread. That means that the stack trace of
the exception doesn't have the calling method which is *super* *ultra*
confusing.
This change always wraps exceptions transferred from the async thread
pool so that the stack trace of the thrown exception contains the
caller's stack. It tries to preserve the type of the throw exception but
this is quite a fiddly thing to get right. We have to catch every type
of exception that we want to preserve, wrap with the same type and
rethrow. I've preserved the types of all exceptions that we had tests
mentioning but no other exceptions. The other exceptions are either
wrapped in `IOException` or `RuntimeException`.
Closes#28399
The serialization changes for rejected execution exceptions has been
backported to 6.x with the intention to appear in all versions since
6.3.0. Therefore, this BWC layer is no longer needed in master since
master would never speak to a node that does not speak the same
serialization.
The rejected execution handler API says that rejectedExecution(Runnable,
ThreadPoolExecutor) throws a RejectedExecutionException if the task must
be rejected due to capacity on the executor. We do throw something that
smells like a RejectedExecutionException (it is named
EsRejectedExecutionException) yet we violate the API because
EsRejectedExecutionException is not a RejectedExecutionException. This
has caused problems before where we try to catch RejectedExecution when
invoking rejectedExecution but this causes EsRejectedExecutionException
to go uncaught. This commit addresses this by modifying
EsRejectedExecutionException to extend
RejectedExecutionException.
Adds support for triple quoted strings to the documentation test
generator. Kibana's CONSOLE tool has supported them for a year but we
were unable to use them in Elasticsearch's docs because the process that
converts example snippets into tests couldn't handle this. This change
adds code to convert them into standard JSON so we can pass them to
Elasticsearch.
I have seen this question a couple times already, most recently at
https://twitter.com/dimosr7/status/973872744965332993
I tried to keep the explanation as simple as I could, which is not always easy
as this is a matter of trade-offs.
The settings `indices.recovery.concurrent_streams` and
`indices.recovery.concurrent_small_file_streams` were removed in
f5e4cd4616. This commit removes their last traces
from the codebase.
Today the synced-flush always issues a new sync-id even though all
shards haven't been changed since the last seal. This causes active
shards to have different a sync-id from offline shards even though all
were sealed and no writes since then.
This commit adjusts not to renew sync-id if all active shards are sealed
with the same sync-id.
Closes#27838
This commit (which will be reverted soon) adds logging on the output of
starting Wildfly. This is needed to debug an issue with Wildfly not
starting in CI.
The index prefix field is normally indexed as docs-only, given that it cannot
be used in phrases. However, in the case that the parent field has been indexed
with offsets, or has term-vector offsets, we should also store this in the index
prefix field for highlighting.
Note that this commit does not implement highlighting on prefix fields, but
rather ensures that future work can implement this without a backwards-break
in index data.
Closes#28994
The cd command on Windows has an oddity regarding changing
directories. If the drive of the current directory is a different drive
than than of the directory that was passed to the cd command, cd acts in
query mode and does not change the current directory. Instead, a flag is
needed to put the cd command into set mode so that the directory
actually changes. This causes a problem when starting Elasticsearch from
a directory different than the one where it is installed and this commit
fixes the issue.
The method `PersistentTasksClusterService.finishTask()` has been
modified since it was added and does not use any `removeOncompletion`
flag anymore. Its behavior is now similar to `removeTask()` and can be
replaced by this one. When a non existing task is removed, the cluster
state update task will fail and its `source` will still indicate
`finish persistent task`/`remove persistent task`.
Additionally:
* Included the existing update by query java api docs in java-api docs.
(for some reason it was never included, it needed some tweaking and
then it was good to go)
* moved delete-by-query / update-by-query code samples to java file so
that we can verify that these samples at least compile.
Closes#24203
Today we allow any other method of starting Elastisearch to override
jvm.options via ES_JAVA_OPTS. Yet, for some settings in the Windows
service, we do not allow this. This commit removes this in favor of
being consistent with other packaging choices.
This commit enhances the error messages reported when JAVA_HOME and
RUNTIME_JAVA_HOME are not correctly set to point towards the minimum
compiler and minimum runtime JDKs that are expected by the builds. The
previous error message would say:
Java 1.9 or above is required to build Elasticsearch
which is confusing if the user does have a JDK 9 installation and is
even the version that they have on their path yet they have JAVA_HOME
pointing to another JDK installation. The error message reported after
this change is:
the environment variable JAVA_HOME must be set to a JDK installation directory for Java 1.9 but is [/usr/java/jdk-8] corresponding to [1.8]
* CLI Command: MultiCommand must close subcommands to release resources properly
- Changes are done to override the close method and call close on subcommands using IOUtils#close
- Unit Test
Closes#28953
Currently ESIndexLevelReplicationTestCase executes write operations
without acquiring index shard permit. This may prevent the primary term
on replica from being updated or cause a race between resync and
indexing on primary. This commit ensures that write operations are
always executed under shard permit like the production code.
Changes made in #28972 seems to have changed some assumptions about how
SMILE and CBOR write byte[] values and how this is tested. This changes
the generation of the randomized DocumentField values back to BytesArray
while expecting the JSON and YAML deserialisation to produce Base64
encoded strings and SMILE and CBOR to parse back BytesArray instances.
Closes#29080
I also had to make the test more lenient. This is due to the fact that
Lucene's RamUsageTester was changed in order not to reflect `java.*`
classes and the way that it estimates ram usage of maps is by assuming
it has similar memory usage to an `Object[]` array that stores all keys
and values. The implementation in `LiveVersionMap` tries to be slightly
more realistic by taking the load factor and linked lists into account,
so it usually gives a higher estimate which happens to be closer to
reality.
Closes#22548
Provide more actionable error message when installing an offline plugin
in the plugins directory, and the `plugins` directory for the node
contains plugin distribution.
Closes#27401
When parsing GetResponse it was possible that the equality check failed because
items in the map were in a different order (in the `.equals` implementation).
The Java API documentation for index administration currenty is wrong because
the PutMappingRequestBuilder#setSource(Object... source) an
CreateIndexRequestBuilder#addMapping(String type, Object... source) methods
delegate to methods that check that the input arguments are valid key/value
pairs. This changes the docs so the java api code examples are included from
documentation integration tests so we detect compile and runtime issues earlier.
Closes#28131
By the time the master branch is released the deprecated url
parameters in the `/_cache/clear` API will have been deprecated
for a couple of minor releases. Since master will be the next
major release we are fine with removing these parameters.
Currently we have a fairly complicated logic in the engine constructor logic to deal with all the
various ways we want to mutate the lucene index and translog we're opening.
We can:
1) Create an empty index
2) Use the lucene but create a new translog
3) Use both
4) Force a new history uuid in all cases.
This leads complicated code flows which makes it harder and harder to make sure we cover all the
corner cases. This PR tries to take another approach. Constructing an InternalEngine always opens
things as they are and all needed modifications are done by static methods directly on the
directory, one at a time.
* 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
When we copied IOUtils into the Elasticsearch codebase from Lucene, we
brought with it its handling of throwables which are out of whack with
how we handle throwables in our codebase. This commit modifies our copy
of IOUtils to be consistent with how we handle throwables today: do not
catch them. We take advantage of this cleanup to simplify IOUtils.
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
If the default java.io.tmpdir is used then the startup script creates
it, but if a custom java.io.tmpdir is used then the user must ensure it
exists before running Elasticsearch. If they forget then it can cause
errors that are hard to understand, so this change adds an explicit
check early in the bootstrap and reports a clear error if java.io.tmpdir
is not an accessible directory.
Eclipse Oxygen doesn't seem to be able to infer the correct type
arguments for Arrays::asList in the given test context. Adding cast to
make this more explicit.
