CompressedString relied on the assumption that two CompressedString instanes
are equal if there compressed representation are equal. Unfortunately this is
not always true because the compressed representation also depends on when
flush() was called on the output stream or on the size of the hash table that
has been used at compression time.
When index is introduced into the cluster via cluster upgrade, restore or as a dangled index the MetaDataIndexUpgradeService checks if this index can be upgraded to the current version. If upgrade is not possible, the newly upgraded cluster startup and restore process are aborted, the dangled index is imported as a closed index that cannot be open.

This commit also reenables CorruptedFileTest#testReplicaCorruption which had
a missing `GatewayAllocator.INDEX_RECOVERY_INITIAL_SHARDS: "one"` setting.
Closes#11226
When we use unicast discovery in tests, we test for available ports by binding to ports and if
the bind was successful, we use that port. This has a timing issue on certain operating systems
the socket can still be in a TIME_WAIT causing subsequent binds to fail before a certain timeout.
Setting reuse address on the Java socket will instruct the underlying operating system to allow
the socket to be bound to immediately, usually by specifying the SO_REUSEADDR socket option.
This commit makes FilteredQuery a forbidden API and also removes some more usage
of the Filter API. There are some remaining code using filters for parent/child
queries but I'm not touching this as they are already being refactored in #6511.
Add a test that verifies that even though all replicas are corrupted on all available nodes, and listing of shard stores faield, it still get allocated and properly recovered from the primary shard
Some requests in the SyncedFlushService were sill blocking on network
calls which made calling this service error prone if done on a network
thread. This commit makes this service fully async based on ActionListener.
This change simplifies the users of the mapper service to no
longer have access to multiple fields for a single name. While
FieldMappersLookup still stores and gives access to multiple
fields, the current users of SmartNameFieldMappers already all
assumed a single field. The arbitrary selection of that field
when multiple exist is now isolated to the mapper service.
When testing, each jvm gets its own tmpdir set, so it may not exist
at all. A Lucene test rule ensures its created, but some tests (I
am looking at you rest tests) do a bunch of file stuff in static {},
in that case because its a parameterized test. And if you try to
extend it, it will fail if security manager is disabled...
Currently we ensure(java.io.tmpdir) very early when tests are running under
security manager, but otherwise we don't and it won't happen until the
test rule fires. So just do it early always.
This behavior has changed been changed rescently to throw an IAE if
the translog we try to read from is already outdated. This is not
the expected behavior and this commit adds back the `old` way returning
`null` instead. The InternalEngine implementation will then go and ask the
lucene index for the document instead.
In some cases due to calling checking `rarely()` the `indexRandom()` method
can potentially flush, which creates flush requests, that miss a certain
header in this test and allow the test to fail.
In addition unused configuration code for this test has been removed.
We used to double write the translog operation which is not needed except
of for recovery. This commit cuts over to a big-array based temporary serialiation
and removes the crazy double writing.
