Most of the abstract base test classes we have were previously @Ignored.
However, there were also some other tests ignored. Having two ways to
quiet tests is confusing, and clearly it has caused some tests
to get lost in the fold.
This change moves all base test classes to use the "TestCase" suffix,
which is not picked up by the test class name pattern. It also removes
@Ignore from (almost) all tests, and adds it to forbidden apis.
And since we were renaming, I shorted base test class names to use
"ES" instead of "Elasticsearch". I type this a lot of types a day,
and I have heard others express a similar desire for a shorter name.

Now that integ tests are moved into `mvn verify`, we don't really have
a need for @Slow, and especially not @Integration. This removes
uses of the first, and completely removes uses of the latter.
Tasks can be registered with a timeout, which runs as a task in a separate
threadpool. The idea is that the timeout runner cancels the main task when
the time is out, and the timeout runner is cancelled when the main task
starts executing. However, the following statement:
```java
timeoutFuture = timer.schedule(new Runnable() {
@Override
public void run() {
if (remove(TieBreakingPrioritizedRunnable.this)) {
runAndClean(timeoutCallback);
}
}
}, timeValue.nanos(), TimeUnit.NANOSECONDS);
```
is not atomic: the removal task is first started, and then the (volatile)
variable is assigned. As a consequence, there is a short window that allows
a timeout task to wait until the time is out even if the task is already
completed.
See http://build-us-00.elastic.co/job/es_core_17_centos/496/ for an example of
such a failure.
Previously only the first aggregation in a buckets_path was check to make sure the aggregation existed. Now the whole path is checked to ensure an aggregation exists at each element in the buckets_path
Closes#12360
Its not going to work: its blocked by security policy
and will just add a confusing SecurityException to the mix, and
bogusly give an exit status of 0 when in fact something bad happened.
Finally, if ES can't startup, it is a serious problem, there is
no sense in hiding the reason why: deliver the full stack trace.
The repository verification process should create a subdirectory to make sure we check permission of newly created directories in case elasticsearch processes on different nodes are running using different uids and creating blobs with incompatible permissions.
Closes#11611
Previously we issued a reroute when a node went over the high watermark
in order to move shards away from the node. This change tracks nodes
that have previously been over the high or low watermarks and issues a
reroute when the node goes back underneath the watermark.
This allows shards that may be unassigned to be assigned back to a node
that was previously over the low watermark but no longer is.
Resolves#12422
As windows has different line endings and this has
already been fixed by another test, the method has been
moved into CliToolTestCase.
In addition one test has been removed, as it was redundant.
In order to ensure, we have the same experience across operating systems
and shells, this commit uses the java CLI parser instead of the shell
getopt parsing to parse arguments.
This also allows for support for paths, which contain spaces.
Also commons-cli depdency was upgraded to 1.3.1 and tests have been added.
Changes
* new exit code, OK_AND_EXIT, allowing to tell the caller to exit, as everything
went as expected (e.g. when running a version output)
BWC breaking:
* execute() returns an ExitStatus instead of an integer, otherwise there is no
possibility to signal by a command, if the JVM should be exited after a run.
This affects plugins, that have command line tools
* -v used to be version, but is a verbose flag by default in the current CLI infra,
must be -V or --version now
* -X has been removed - the current implementation was useless anyway, as
it prefixed those properties with "es.". You should use
ES_JAVA_OPTS/JAVA_OPTS for JVM configuration
Date math index name resolution enables you to search a range of time-series indices, rather than searching all of your time-series indices and filtering the the results or maintaining aliases. Limiting the number of indices that are searched reduces the load on the cluster and improves execution performance. For example, if you are searching for errors in your daily logs, you can use a date math name template to restrict the search to the past two days.
The added `ExpressionResolver` implementation that is responsible for resolving date math expressions in index names. This resolver is evaluated before wildcard expressions are evaluated.
The supported format: `<static_name{date_math_expr{date_format|timezone_id}}>` and the date math expressions must be enclosed within angle brackets. The `date_format` is optional and defaults to `YYYY.MM.dd`. The `timezone_id` id is optional too and defaults to `utc`.
The `{` character can be escaped by places `\\` before it.
Closes#12059
When we rewrite to a MatchNoTermsQuery we were throwing out the boost which
could could lead to funky changes when the query against _all was in a
bool query.
Previously we would write the entire ByteBuffer to the stream to serialise the HDRHistogram even if it was not all needed. Now we only write the bytes that are actually written to in the ByteBuffer.
We currently test the toQuery method by comparing its return value with the output of createExpectedQuery. This seemed at first like a good deep test for the lucene generated queries, but ends up causing a lot of code duplication between tests and prod code, which smells like this test is not that useful after all.
This commit removes the requirement for createExpectedQuery, we test a bit less the lucene generated queries, but we do still have a testToQuery method in BaseQueryTestCase. This test acts as smoke test to verify that there are no issues with our toQuery method implementation for each query: it verifies that two equal queries should result in the same lucene query. It also verifies that changing the boost value of a query affects the result of the toQuery.
Part of the previous createExpectedQuery can be moved to assertLuceneQuery using normal assertions, we do it when it makes sense only though.
This commit also adds support for boost and queryName to SpanMultiTermQueryParser and SpanMultiTermQueryBuilder, plus it removes no-op setters for queryName and boost from QueryFilterBuilder. Instead we simply declare in our test infra that query filter doesn't support boost and queryName and we disable tests aroudn these fields in that specific case. Boost and queryName support is also moved down to the QueryBuilder interface.
Closes#12473
This can happen in two ways:
1. The _all field is disabled.
2. There are documents in the index, the _all field is enabled, but there are
no fields in any of the documents.
In both of these cases we now rewrite the query to a MatchNoDocsQuery which
should be safe because there isn't anything to match.
Closes#12439
When a node discovers shard content on disk which isn't used, we reach out to all other nodes that supposed to have the shard active. Only once all of those have confirmed the shard active, the shard has no unassigned copies *and* no cluster state change have happened in the mean while, do we go and delete the shard folder.
Currently, after removing a shard, the IndicesStores checks the indices services if that has no more shard active for this index and if so, it tries to delete the entire index folder (unless on master node, where we keep the index metadata around). This is wrong as both the check and the protections in IndicesServices.deleteIndexStore make sure that there isn't any shard *in use* from that index. However, it may be the we erroneously delete other unused shard copies on disk, without the proper safety guards described above.
Normally, this is not a problem as the missing copy will be recovered from another shard copy on another node (although a shame). However, in extremely rare cases involving multiple node failures/restarts where all shard copies are not available (i.e., shard is red) there are race conditions which can cause all shard copies to be deleted.
Instead, we should change the decision to clean up an index folder to based on checking the index directory for being empty and containing no shards.
This change creates a proper `distribution` modules in which we have today packaging for
all of our four current packages:
* zip
* tar.gz
* rpm
* deb
Licenes have moved into the distribution project as well. So have the config/ and the bin/ directory
from the core/ project.
The RPM package is now built, if rpmbuild exists.
The bats tests have been moved as well.
Also the zip distribution now executes the REST integration tests.
As Robert pointed out on #12465, it has the undesirable property of relying on
the operating system. So it would be better to use a simple rule such as
checking whether the file name starts with a dot.
When an index is opened it will not be assigned to a node but also not have closed state
anymore. Before we only checked if an index either is closed or assigned to the data node
and therefore the change from close->open was not written.
Some of the test for meta data are redundant. Also, since they
somewhat test service disruptions (start master with empty
data folder) we might move them to DiscoveryWithServiceDisruptionsTests.
Also, this commit adds a test for
https://github.com/elastic/elasticsearch/issues/11665
If we cache the type filter and we e.g. set its boost which is now settable on all queries, the boost will change for all subsequent queries. We should rather create a new query every time.
Major changes:
* Changed MetaData to holds alias and index lookup information into a single TreeMap instead of two separate maps.
* Moved the building of the alias / index lookup to the metadata builder.
Settings are currently parsed by looping over the tokens until an END_OBJECT token is reached. However, this does not mean that the end of
the settings stream was reached. This can occur, for example, when parsing a YAML settings file with inconsistent indentation. Currently
in this case, some settings will be silently ignored. This commit forces a check that we have in fact reached the end of the settings
stream.
Closes#12382
HDRHistogram has been added as an option in the percentiles and percentile_ranks aggregation. It has one option `number_significant_digits` which controls the accuracy and memory size for the algorithm
