This commit removes the timeout retry mechanism from ShardStateAction
allowing it to instead be handled by the general master channel retry
mechanism. The idea is that if there is a network issue, the master will
miss a ping timeout causing the channel to be closed which will expose
itself via a NodeDisconnectedException. At this point, we can just wait
for a new master and retry, as with any other master channel exception.
This commit moves the handling of channel failures when failing a shard
to o.e.c.a.s.ShardStateAction. This means that shard failure requests
that timeout or occur when there is no master or the master leaves after
the request is sent will now be retried from here. The listener for a
shard failed request will now only be notified upon successful
completion of the shard failed request, or when a catastrophic
non-channel failure occurs.
This commit adds a simulation of the master leaving after a shard
failure request has been sent. In this case, after a new cluster state
is published (simulating a new master having been elected), the request
to fail the shard should be retried.
This commit handles the situation when we are failing a shard and either
no master is known, or the known master left while failing the shard. We
handle this situation by waiting for a new master to be reelected, and
then sending the shard failed request to the new master.
Adding serialization capabilities to RescoreBuilder and make
all QueryRescorer implement NamedWritable, also requiring
all implementations of RescoreBuilder.Rescorer to implement
equals() and hashCode.
In addition, the current rescore mode enumeration is pulled out to a
separate class to make sharing of constants easier between
the query builders XContent rendering coder and the parser.
This change affects get alias, get aliases as well as cat aliases. They all return closed indices too by default. get alias and get aliases also allow to return open indices only through the `expand_wildcards` option (set it to `open`).
Closes#14982
This undocumented setting was mainly used for testing and a safety net for
a new flushOnClose feature back in 1.x. We can now safely remove this setting.
The test usage now uses a mock plugin setting to achive the same.
Today we maintain a lot of settings on the shard level which are all index level settings.
In order to cut over to the new settings API where we register update listener we have to move
all of them on to the index level otherwise we need a way to un-register listeners which is error-prone
and requires additional handling when shards are closed. It's simpler and also more accurate to handle all of
them on the index level where we can trash the entire registry for update listener once the index goes out of scope.
Don't set the suppressed Exception in Translog.closeOnTragicEvent(Exception ex) if it is an
AlreadyClosedException. ACE is thrown by the TranslogWriter and as cause might
contain the Exception that we add the suppressed ACE to. We then end up with a
circular reference where Exception A has a suppressed Exception B that has as cause A.
This would cause a stackoverflow when we try to serialize it.

This commit adds load averages to the OS stats on FreeBSD. For these
stats to be available, linprocfs must be available and mounted at
/compat/linux/proc.
`refresh_interval` is a per index setting but we interpret and maintain it per shard. This
change moves the refresh task outside of IndexShard to the IndexService where it logically belongs
and reuses scheduling infrastructure used for translog fsync (async commit).
This change will use the same task for all shards of an index while previously we used on thread/task
per shard to refresh. This will also prevent too many concurrent refreshes if there are many indices and
shards allocated on a single node.
These filters leak into highlighting and probably other places and cause
things like the type name to be highlighted when using
requireFieldMatch=false. We could have special hacks to keep them out of
highlighting but it feals better to keep them out of any variable named
"originalQuery".
Closes#15689
This commit adds convenience methods to o.e.t.t.CapturingTransport
that enables capturing requests and clearing the captured requests
with a single method. This is to simplify a common pattern in tests of
capturing requests, and then clearing the captured requests.
Also renaming internal methods to reflect that they are dealing with
jts coordinates. Also renamed the list() to build() method for creating
the coordinates lists and adding constructors to PolygonBuilder that
take CoordinatesBuilders and implicitely call build() on them.
The indexing buffer on a node (default: 10% of the JVM heap) is now a "shared pool" across all shards on that node. This way, shards doing intense indexing can use much more than other shards doing only light indexing, and only once the sum of all indexing buffers across all shards exceeds the node's indexing buffer will we ask shards to move recently indexed documents to segments on disk.
determined, the UpdateRequest would still try to parse the content instead
of throwing the standard ElasticsearchParseException. This manifests when
passing illegal JSON in the request body that does not begin with a '{'.
By trying to parse the content from an unknown request body content type,
the UpdateRequest was throwing a null pointer exception. This has been
fixed to throw an ElasticsearchParseException, to be consistent with the
behavior of all other requests in the face of undecipherable request
content types.

1. Uses forbidden patterns to prevent things from referencing
java.io.Serializable or from mentioning serialVersionUID.
2. Uses -Xlint:-serial so we don't have to hear from javac that we aren't
declaring serialVersionUID on any classes that we make that happen to extend
Serializable.
3. Remove Serializable and serialVersionUID declarations.
I didn't use forbidden apis because it doesn't look like it has a way to ban
explicitly implementing Serializable. If you try to ban Serializable with
forbidden apis you end up banning all Exceptions and all Strings.
Closes#15847
So far the validation of geo shapes was only taking place in the
parse methods in ShapeBuilder. With the recent refactoring we no
longer can rely on shapes being parsed from json, so the same kind
of validation should take place when just using the java api.
A lot of validation concerns the number of points a shape needs to
have in order to be valid. Since this is not possible with current
builders where points can be added one by one, the builder constructors
are changed to require the mandatory parameters and validate those
already at construction time. To help with constructing longer lists
of points, a new utility PointsListBuilder is instroduces which can
produce list of coordinates accepted by most of the other shape builder
constructors.
Also adding tests for invalid shape exceptions to the already existing
shape builder tests.
Running requests via the percolate or mpercolate api is irrelevant.
What is relevant is that when nodes come back that they report the expected number of matches.
We fail today with ClusterBlockExceptions if an alias expands to a closed index
during search since we miss to check the index option down the road after we expanded
aliases.
Closes#13278
This commit removes and now forbids use of
org.apache.lucene.index.IndexWriter#isLocked as this method was
deprecated in LUCENE-6508. The deprecation is due to the fact that
checking if a lock is held before acquiring that lock is subject to a
time-of-check-to-time-of-use race condition. There were three uses of
IndexWriter#isLocked in the code base:
- a logging statement in o.e.i.e.InternalEngine where we are already in
an exceptional condition that the lock was held; in this case,
logging whether or not the directory is locked is superfluous
- in o.e.c.l.u.VersionsTests where we were verifying that a write lock
is released upon closing an IndexWriter; in this case, the check is
not needed as successfully closing an IndexWriter releases its
write lock
- in o.e.t.s.MockFSDirectoryService where we were verifying that a
directory is not write-locked before (implicitly) trying to obtain
such a write lock in org.apache.lucene.index.CheckIndex#<init> (this
is the exact type of a situation that is subject to a race
condition); in this case we can proceed by just (implicitly) trying
to obtain the write lock and failing if we encounter a
LockObtainFailedException
This commit reduces the former ShardIndexinService to a simple stats/metrics
class, moves IndexingSlowLog to the IndexService level since it can be shared
across shards of an index and is now hidden behind IndexingOperationListener.
IndexingOperationListener is now a first class citizen in IndexShard and is passed
in from IndexService.
It had some funky errors, like lenient:true not working and queries with
two integer fields blowing up if there was no analyzer defined on the
query. This throws a bunch more tests at it and rejiggers how non-strings
are handled so they don't wander off into scary QueryBuilder-land unless
they have a nice strong analyzer to protect them.
Closes#15860
It currently tries to align to the page size (16KB) by default. However, this
might waste a significant memory (if many BytesStreamOutputs are allocated)
and is also useless given that BytesStreamOutput does not recycle (on the
contrary to ReleasableBytesStreamOutput). So the initial size has been changed
to 0.
Closes#15789
This commit removes and now forbids all uses of
java.util.concurrent.ThreadLocalRandom across the codebase. The
underlying issue with ThreadLocalRandom is that it can not be
seeded. This means that if ThreadLocalRandom is used in production code,
then tests that cover any code path containing ThreadLocalRandom will be
prevented from being reproducible by use of ThreadLocalRandom. Instead,
using org.elasticsearch.common.random.Randomness#get will give
reproducible sources of random when running under tests and otherwise
still give an instance of ThreadLocalRandom when running as production
code.
On slow machines when this test randomly picks a large number of shards it can occasionally take more than 32.5 seconds to snapshot all shards. That is causing the test to miss the second to last assert in awaitsBusy at 32.5 seconds and then timeout in BlockingClusterStateListener at 60 seconds. Due to the timeout, the pending task queue is cleaned before the last awaitsBusy assert at 65 seconds and as a result the last assert runs on a completely empty queue and fails with a very confusing assert error.
This commit makes the timeout in BlockingClusterStateListener to occur after the last assert in assertBusyPendingTasks and therefore allows assertBusyPendingTasks to perform the last assert before cleaning the pending tasks queue takes place.
This commit also reduces the maximum number of shards used in the test to 10 in order to speed up this test.
We have a bug that makes all per-index bitset caches store bitsets for all
indices. In the case that you have many indices, which is fairly common with
time-based data, this could translate to a lot of wasted memory.
Closes#15820
`ScheduledThreadPoolExecutor` allows you to schedule tasks to run once or periodically at the future. If such a task throws an exception, that exception is caught and reported in the future that `ScheduledThreadPoolExecutor#schedule` returns. However, we typically do not capture the future / do not test it for errors. This results in exception being swallowed and not reported. To mitigate this we now wrap any command in a LoggingRunnable (already used for periodic tasks). Also, RunnableCommand is changed not to swallow exception but percolate them further for reporting by the future.
Closes#15824
This commit adds a new test that can throw an IOException at any point in time
and ensures that all previously synced documents can be successfully recovered after hitting
an excepiton.

Warmers are now barely useful and will be removed in 3.0. Note that this only
removes the warmer API and query-based warmers. We still have warmers internally
for eg. global ordinals.
Close#15607
Right now we define the same sort of methods as taking String arrays and
string varargs. We should standardize on one and varargs is easier to
call so lets use varargs!
