Sorry for the longer stack trace, but I wanted to be sure I didn't throw
anything away by accident.
* master:
Fix REST test documentation
[Test] move methods from bwc test to test package for use in plugins (#19738)
package-info.java should be in src/main only.
Split regular histograms from date histograms. #19551
Tighten up concurrent store metadata listing and engine writes (#19684)
Plugins: Make NamedWriteableRegistry immutable and add extenion point for named writeables
Add documentation for the 'elasticsearch-translog' tool
[TEST] Increase time waiting for all shards to move off/on to a node
Fixes the active shard count check in the case of (#19760)
Fixes cat tasks operation in detailed mode
ignore some docker craziness in scccomp environment checks
We just overwrite `toString()` method so it calls toXContent
with `group_by` = "whatever" so we don't try to group by nodes
which does not make sense in a toString() method.
We keep the old behavior for `toXContent()` method which
means that there is no impact in the REST layer but
only in logs and tests (where we call `toString()`).
Closes#19772.
To run the tests we have to use now `*Yaml*IT` instead of `RestIT`:
```sh
gradle :distribution:integ-test-zip:integTest -Dtests.class=org.elasticsearch.test.rest.*Yaml*IT
```
Currently both aggregations really share the same implementation. This commit
splits the implementations so that regular histograms can support decimal
intervals/offsets and compute correct buckets for negative decimal values.
However the response API is still the same. So for intance both regular
histograms and date histograms will produce an
`org.elasticsearch.search.aggregations.bucket.histogram.Histogram`
aggregation.
The optimization to compute an identifier of the rounded value and the
rounded value itself has been removed since it was only used by regular
histograms, which now do the rounding themselves instead of relying on the
Rounding abstraction.
Closes#8082Closes#4847
In several places in our code we need to get a consistent list of files + metadata of the current index. We currently have a couple of ways to do in the `Store` class, which also does the right things and tries to verify the integrity of the smaller files. Sadly, those methods can run into trouble if anyone writes into the folder while they are busy. Most notably, the index shard's engine decides to commit half way and remove a `segment_N` file before the store got to checksum (but did already list it). This race condition typically doesn't happen as almost all of the places where we list files also happen to be places where the relevant shard doesn't yet have an engine. There is however an exception (of course :)) which is the API to list shard stores, used by the master when it is looking for shard copies to assign to.
I already took one shot at fixing this in #19416 , but it turns out not to be enough - see for example https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+multijob-os-compatibility/os=sles/822.
The first inclination to fix this was to add more locking to the different Store methods and acquire the `IndexWriter` lock, thus preventing any engine for accessing if if the a shard is offline and use the current index commit snapshotting logic already existing in `IndexShard` for when the engine is started. That turned out to be a bad idea as we create more subtleties where, for example, a store listing can prevent a shard from starting up (the writer lock doesn't wait if it can't get access, but fails immediately, which is good). Another example is running on a shared directory where some other engine may actually hold the lock.
Instead I decided to take another approach:
1) Remove all the various methods on store and keep one, which accepts an index commit (which can be null) and also clearly communicates that the *caller* is responsible for concurrent access. This also tightens up the API which is a plus.
2) Add a `snapshotStore` method to IndexShard that takes care of all the concurrency aspects with the engine, which is now possible because it's all in the same place. It's still a bit ugly but at least it's all in one place and we can evaluate how to improve on this later on. I also renamed the `snapshotIndex` method to `acquireIndexCommit` to avoid confusion and I think it communicates better what it does.
In 2.0, the ability to specify metadata fields like _routing and _ttl
inside a document was removed. However, the ability to break through
this restriction has lingered, and the check that enforced it is
completely broken.
This change fixes the check, and adds a parsing test.
Currently any code that wants to added NamedWriteables to the
NamedWriteableRegistry can do so via guice injection of the registry,
and registering at construction time. However, this makes the registry
complex: it has both get and register methods synchronized, and there is
likely contention on the read side from multiple threads. The
registration has mostly already been contained to guice modules at node
construction time.
This change makes the registry immutable, taking all of the
NamedWriteable readers at construction time. It also allows plugins to
added arbitrary named writables that it may use in its own transport
actions.
ActiveShardCount.ALL by checking for active shards,
not just started shards, as a shard could be active
but in the relocating state (i.e. not in the started
state).
conform with the requirements of the writeBlob method by
throwing a FileAlreadyExistsException if attempting to write
to a blob that already exists. This change means implementations
of BlobContainer should never overwrite blobs - to overwrite a
blob, it must first be deleted and then can be written again.
Closes#15579
* Allow to run client benchmark as an uberjar
* Busy wait to avoid accidental skew on low target throughput rates
* Trigger and wait for full GC to happen between trials
* Add missing SuppressForbidden to allow System.gc in client benchmark
With this commit we add documentation and additional checks to
enforce the cancellation policy of CancellableThreads (which is
disallow `Thread#interrupt()` on any of the threads managed by
it).
This fixes a bug in the RunningStats class for the matrix stats aggregation module. doc counts were not being searlized which means they were only computed the first time the aggregation was computed. This was causing incorrect results when the aggregation was pulled from cache.
If the uuidBytes and ref are converted to utf8, it's possible they can
trip an assertion related to valid UTF-8/UTF-16 ranges, so display them
as hex, not as strings.
method to determine if a write consistency check should be performed
before proceeding with the action. This commit removes this method from
the transport replication actions in favor of setting the ActiveShardCount
on the request, with setting the value to ActiveShardCount.NONE if the
transport action's checkWriteConsistency() method returned false.
