Without this change, if write a script with multiple regexes
*sometimes* the lexer will decide to look at them like one
big regex and then some trailing garbage. Like this discuss post:
https://discuss.elastic.co/t/error-with-the-split-function-in-painless-script/79021
```
def val = /\\\\/.split(ctx._source.event_data.param17);
if (val[2] =~ /\\./) {
def val2 = /\\./.split(val[2]);
ctx._source['user_crash'] = val2[0]
} else {
ctx._source['user_crash'] = val[2]
}
```
The error message you get from the lexer is `lexer_no_viable_alt_exception`
right after the *second* regex.
With this change each regex is just a single regex like it ought to be.
As a bonus, while looking into this issue I found that the error
reporting for regexes wasn't very nice. If you specify an invalid
pattern then you get an error marker on the start of the pattern
with the JVM's regex error message which attempts to point you to the
location in the regex but is totally unreadable in the JSON response.
This change fixes the location to point to the appropriate spot
inside the pattern and removes the portion of the JVM's error message
that doesn't render well. It is no longer needed now that we point
users to the appropriate spot in the pattern.
A previous attempt to address a race condition in this test set wait for
active shards to all. However, there might not be any replicas if the
test is only running with one node so we end up waiting
forever. Instead, to address the intial race condition, we just count
through the primary.
In #23638 we renamed `request_cache` to `request` in the
`_cache/clear` API. But it is only going to be committed back to
5.x so we can't test with the new name in a mixed version
cluster.
This test executes a bulk indexing operation with two documents. If this
test is running against multiple nodes, there are no guarantees that all
shards are green before we execute a search operation which might hit a
replica shard. This commit creates the index in advance, and waits for
all shards to be active before proceeding with the indexing request.
The output of the different implementations of terms aggs is always very similar. The toXContent methods for each of those classes though was duplicating almost the same code multiple times. This commit centralizes the code for rendering XContent to a single place, which can be reused from the different terms aggs implementations.
This commit adds a build listener to the integ test runner which will
print out an excerpt of the logs from the integ test cluster if the test
run fails. There are future improvements that can be made (for example,
to dump excerpts from dependent clusters like in tribe node tests), but
this is a start, and would help with simple rest tests failures that we
currently don't know what actually happened on the node.
We currently use POSIX exit codes in all of our CLIs. However, posix
only suggests these exit codes are standard across tools. It does not
prescribe particular uses for codes outside of that range. This commit
adds 2 exit codes specific to plugin installation to make distinguishing
an incorrectly built plugin and a plugin already existing easier.
closes#15295
This commit catches the underlying failure when trying to list plugin
information when a plugin is incompatible with the current version of
elasticsearch. This could happen when elasticsearch is upgraded but old
plugins still exist. With this change, all plugins will be output,
instead of failing at the first out of date plugin.
closes#20691
Changes reindex and friends to wait until the entire request has
been "cleaned up" before responding. "Clean up" in this context
is clearing the scroll and (for reindex-from-remote) shutting
down the client. Failures to clean up are still only logged, not
returned to the user.
Closes#23653
After the removal of the joda time hack we used to have, we can cleanup
the codebase handling in security, jarhell and plugins to be more picky
about uniqueness. This was originally in #18959 which was never merged.
closes#18959
This commit removes the hardcoded list of plugins used by the smoke
tester and instead loads this list the same way the build does: by
looking for directories under the `plugins` dir.
closes#13096
The SharedClusterSnapshotRestoreIT#testDataFileCorruptionDuringRestore
would fail sporadically because it tried to simulate restoring a
corrupted index. The test would wait until the restore is finished (and
marked as failed) before exiting. However, in the background, the
cluster still continues to retry allocation of the failed shards,
despite the restore operation being marked as completed, which in turn
generates cluster states to process. The end of every ESIntegTestCase
verifies that none of the nodes have any pending cluster states to
process. Hence, this check sometimes fails on this particular test.
This commit solves the issue by ensuring the index is deleted before
exiting the test.
This will allow us to get rid of deprecation warnings that appear when
using 3.3, and also get rid of extra logic for 2.13 required because of
the progress logger.
This test asserts that the took time exists by using the is_true
assertion. This assertion fails if the took time was zero as is_true
asserts that the field is not the empty string, not the string "false",
and not 0. If the search returns quickly, and took time is measured
using a high-precision monotonic clock, the took time can be zero. This
commit changes the assertion to use gte.
Search took time uses an absolute clock to measure elapsed time, and
then tries to deal with the complexities of using an absolute clock for
this purpose. Instead, we should use a high-precision monotonic relative
clock that is designed exactly for measuring elapsed time. This commit
modifies the search infrastructure to use a relative clock for measuring
took time, but still provides an absolute clock for the components of
search that require a real clock (e.g., index name expression
resolution, etc.).

A better toString() is added for snapshot operations in progress in the
cluster state and logging has been increased to help debug
SharedClusterSnapshotRestoreIT tests.
This commit creates a keystore and adds settings to it during the
cluster formation for integration tests. Users can define a
`keyStoreSetting` in build files for settings that need to be placed in
the keystore.
MapperService#parentTypes is rewrapped in an UnmodifiableSet in MapperService#internalMerge every time the cluster state is updated. After thousands of updates the collection is wrapped so deeply that calling a method on it generates a StackOverflowError.
Closes#23604
When adding filesystem stats from individual filesystems, free and
available can overflow. This commit guards against this by adjusting
these situations to Long.MAX_VALUE.

This commit marks the EvilJNANativesTests as awaiting fixes due to these
tests failing on platforms that do not provide at least version 2.14 of
glibc.
Currently the task manager is tied to the transport and can only create tasks based on TransportRequests. This commit enables task manager to support tasks created by non-transport services such as the persistent tasks service.
* Add support for fragment_length in the unified highlighter
This commit introduce a new break iterator (a BoundedBreakIterator) designed for the unified highlighter
that is able to limit the size of fragments produced by generic break iterator like `sentence`.
The `unified` highlighter now supports `boundary_scanner` which can `words` or `sentence`.
The `sentence` mode will use the bounded break iterator in order to limit the size of the sentence to `fragment_length`.
When sentences bigger than `fragment_length` are produced, this mode will break the sentence at the next word boundary **after**
`fragment_length` is reached.
This commit changes the method for checking the interrupt status of a
thread that is intentionally interrupted during
AdapterActionFutureTests#testInteruption. Namely, we want to check and
clear the interrupt status before joining on the interrupting thread. If
we do not clear the status, when we lose a race where the interrupting
thread is not yet finished, an interrupted exception will be thrown when
we try to join on it. Clearing the interrupted status on the main thread
addresses this issue.
This commit moves the checkstyle rule of max line length from 140
characters to 100 characters. We whitelist all existing violations and
will address them in follow-ups.
