This will reject mapping updates to the `_default_` mapping with 7.x indices
and still emit a deprecation warning with 6.x indices.

Supersedes #28248
I misunderstood how the bwc versions works. If we backport to 5.x, we
need to backport to all supported 6.*. This commit corrects the BWC
versions for PreSyncedFlushResponse.

* Remove BytesArray and BytesReference usage from XContentFactory
This removes the usage of `BytesArray` and `BytesReference` from
`XContentFactory`. Instead, a regular `byte[]` should be passed. To assist with
this a helper has been added to `XContentHelper` that will preserve the offset
and length from the underlying BytesReference.
This is part of ongoing work to separate the XContent parts from ES so they can
be factored into their own jar.
Relates to #28504
* Add pluggable XContentBuilder writers and human readable writers
This adds the ability to use SPI to plug in writers for XContentBuilder. By
implementing the XContentBuilderProvider class we can allow Elasticsearch to
plug in different ways to encode types to JSON.
Important caveat for this, we should always try to have the class implement
`ToXContentFragment` first, however, in the case of classes from our
dependencies (think Joda classes or Lucene classes) we need a way to specify
writers for these classes.
This also makes the human-readable field writers generic and pluggable, so that
we no longer need to tie XContentBuilder to things like `TimeValue` and
`ByteSizeValue`. Contained as part of this moves all the TimeValue human
readable fields to the new `humanReadableField` method. A future commit will
move the `ByteSizeValue` calls over to this method.

We need to configure the Java 9 checkstyle task to depend on the
checkstyle configuration task or the task could run before the
checkstyle conf has been copied leading to runtime failures. We have to
do this after projects have been evaluated because the configuration of
these tasks can occur before the Java 9 source set has been added to a
project.
This commit fixes the directory name bundled plugins are added under
within a meta plugin to be the configured name of the bundled plugin,
instead of the project name.
This commit creates the copyRestSpec task for rest integ tests
immediately on creation of the RestIntegTestTask instead of lazily in
afterEvaluate. This allows other projects to add additional rest specs
to be copied, instead of needing to create another parallel copy task.
`$_path` is used by documentation tests to ignore a value from a
response, for example:
```
[source,js]
----
{
"count": 1,
"datafeeds": [
{
"datafeed_id": "datafeed-total-requests",
"state": "started",
"node": {
...
"attributes": {
"ml.machine_memory": "17179869184",
"ml.max_open_jobs": "20",
"ml.enabled": "true"
}
},
"assignment_explanation": ""
}
]
}
----
// TESTRESPONSE[s/"17179869184"/$body.$_path/]
```
That example shows `17179869184` in the compiled docs but when it runs
the tests generated by that doc it ignores `17179869184` and asserts
instead that there is a value in that field. This is required because we
can't predict things like "how many milliseconds will this take?" and
"how much memory will this take?".
Before this change it was impossible to use `$_path` when any component
of the path contained a `.`. This fixes the `$_path` evaluator to
properly escape `.`.
Closes#28770
I did a little digging. It looks like IOException is thrown when the other
side closes its connection while we're waiting on our buffer to fill up. We
totally expect that in this test. It feels to me like we should throw a
`ConnectionClosedException` but upstream does not agree:
https://issues.apache.org/jira/browse/HTTPASYNC-134
While we *could* catch the exception and transform it ourselves that
seems like a bigger change than is merited at this point.
Closes#29136
Currently we store the indices specified in the request URL together with all
the other ranking evaluation specification in RankEvalSpec. This is not ideal
since e.g. the indices are not rendered to xContent and so cannot be parsed
back. Instead we should keep them in RankEvalRequest.
This removes the `Text` and `Geopoint` special handling from `XContentBuilder`.
Instead, these classes now implement `ToXContentFragment` and render themselves
accordingly.
This allows us to further decouple XContentBuilder from Elasticsearch-specific
classes so it can be factored into a standalone lib at a later time.
Relates to #28504
This modifies xcontent serialization of Exceptions to contain suppressed
exceptions. If there are any suppressed exceptions they are included in
the exception response by default. The reasoning here is that they are
fairly rare but when they exist they almost always add extra useful
information. Take, for example, the response when you specify two broken
ingest pipelines:
```
{
"error" : {
"root_cause" : ...snip...
"type" : "parse_exception",
"reason" : "[field] required property is missing",
"header" : {
"processor_type" : "set",
"property_name" : "field"
},
"suppressed" : [
{
"type" : "parse_exception",
"reason" : "[field] required property is missing",
"header" : {
"processor_type" : "convert",
"property_name" : "field"
}
}
]
},
"status" : 400
}
```
Moreover, when suppressed exceptions come from 500 level errors should
give us more useful debugging information.
Closes#23392
After elastic/elasticsearch#29109, the `needsReassignment` method has
been moved to the PersistentTasksClusterService. This commit fixes
some compilation in tests I introduced.
This commit consists of small code cleanups and refactorings in the
persistent tasks framework. Most changes are in
PersistentTasksClusterService where some methods have been renamed
or merged together, documentation has been added, unused code removed
in order to improve readability of the code.
Update allocation awareness docs
Today, the docs imply that if multiple attributes are specified the the
whole combination of values is considered as a single entity when
performing allocation. In fact, each attribute is considered separately. This
change fixes this discrepancy.
It also replaces the use of the term "awareness zone" with "zone or domain", and
reformats some paragraphs to the right width.
Fixes#29105
This is a follow up to a previous change which set the error file path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to the root of the
installation (i.e., Elasticsearch home). Therefore, we can specify the
error file path relative to this directory and default it to the logs
directory, similar to the package distributions.
This is a follow up to a previous change which set the heap dump path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to to the root of
installation (i.e., Elasticsearch home). Therefore, we can specify the
heap dump path relative to this directory and default it to the data
directory, similar to the package distributions.
The method Translog#getMinGenerationForSeqNo does not modify the current
translog but only access, it therefore should acquire the readLock
instead of writeLock.
Adds SSLHandshakeException to the list of Exceptions that are
specifically rethrown from the async thread so its type is preserved.
This should make it easier to debug synchronous calls with ssl issues.
When upgrading via the RPM package, we can run into a problem where
the keystore fails to be created. This arises because the %post script
on RPM runs after the new package files are installed but before the
removal of the old package files. This means that the contents of the
lib folder can contain files from the old package and the new package
and thus running the create keystore tool can encounter JAR hell
issues and fail. To solve this, we move creating the keystore to the
%posttrans script which runs after the old package files are
removed. We only need to do this on the RPM package, so we add a
switch in the shared post-install script.
Today we report thread pool info using a common object. This means that
we use a shared set of terminology that is not consistent with the
terminology used to the configure thread pools. This holds in particular
for the minimum and maximum number of threads in the thread pool where
we use the following terminology:
thread pool info | fixed | scaling
min core size
max max size
This commit changes the display of thread pool info to be dependent on
the type of the thread pool so that we can align the terminology in the
output of thread pool info with the terminology used to configure a
thread pool.
A new engine now can have more than one empty translog since #28676.
This cause #testShouldPeriodicallyFlush failed because in the test we
asssume an engine should have one empty translog. This commit takes into
account the extra translog size of a new engine.
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.
