This commit moves the apache and elastic license files into a new
root level `licenses` directory and rewrites the top level LICENSE.txt
to clarify the repository has a mix of apache and elastic licensed code.
This commit adds license metadata to rpm and deb packages. Additionally,
it makes the copyright file for deb files follow the machine readable
specification, and sets the correct license text based on the oss vs
default deb packages.
This commit adapts the license headers check to no longer look for the
ealsticsearch confidential license, but instead to look for the new
Elastic License header.
With the switch to X-Pack as a module, we lost production of POMs for
the JARs that we publish, and did not have a license/notice file in the
zip archives nor the exploded module. This commit ensures that we
generate these POMs, and license/notice files.
X-Pack can no longer be installed as a plugin. This commit adds special
handling for when a user attempts to install X-Pack. This special
handling informs the user of the oss distribution that they should
download the default distribution and the user of the default
distribution that X-Pack does not require installation as it is included
by default.
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
This change updates the WatcherLifecycleService to have its own single
thread executor that is used for lifecycle changes in order to have a
guarantee for the order that the changes are executed in.
Previously, a runnable would be submitted to the generic threadpool for
each lifecycle change that is needed. There was no guarantee of
ordering for these changes and no checks to see if a state change was
already in flight.

The PKI realm has never been a caching realm as the need had not
presented itself until now. The PKI realm relies on role mappings to
map the DN from a certificate to roles so that the users have the
appropriate access permissions. Without caching, this role mapping will
happen on every request. For file based role mappings, this is not an
issue as the mappings are based on equality checks for the DN.
However, the design of the API based role mappings allows for more
complex matches. These matches are implemented using automata, which
are built on every request that needs role mappings. Building automata
is an expensive operation and in combination with the PKI realm's lack
of caching leads to a significant performance impact.
The change in this commit makes the PkiRealm a caching realm using the
same pattern as other caching realms. The cache provided by
elasticsearch core is used to map the fingerprint of a certificate to
the user that was resolved from this certificate. The semantics of
modifications to this cache during iteration requires that we use a
read-write lock to protect access. There can be multiple concurrent
modifications and retrievals but iteration must be protected from any
attempts to modify the cache.
Additionally, some PKI tests were converted to single node tests as
part of this change. One test only used a single node and the other did
not require multiple nodes.

Adds a check in BlobstoreRepository.snapshot(...) that prevents duplicate snapshot names and fails
the snapshot before writing out the new index file. This ensures that you cannot end up in this
situation where the index file has duplicate names and cannot be read anymore .

The suggest stats were folded into the search stats as part of the
indices stats API in 5.0.0. However, the suggest metric remained as a
synonym for the search metric for BWC reasons. This commit deprecates
usage of the suggest metric on the indices stats API.
Similarly, due to the changes to fold the suggest stats into the search
stats, requesting the suggest index metric on the indices metric on the
nodes stats API has produced an empty object as the response since
5.0.0. This commit deprecates this index metric on the indices metric on
the nodes stats API.
This commit implements the ability to remove values from a Cache using
the values iterator. This brings the values iterator in line with the
keys iterator and adds support for removing items in the cache that are
not easily found by the key used for the cache.

Add missing Atan2 & Power(and introduce BinaryMath operations), similar
to MathOperation.
Also align arithmetic package with binary math for code reuse.

When deployed, JDBC version needs to look at jars inside the classpath
not on the file system. Failing to do that, causes the version
information to be missing

Previously we did not put an indexing to a version map if that map does
not require safe access but removed the existing delete tombstone only
if assertion enabled. In #29585, we removed the side-effect caused by
assertion then this test started failing. This failure can be explained
as follows:
- Step 1: Index a doc then delete that doc
- Step 2: The version map can switch to unsafe mode because of
concurrent refreshes (implicitly called by flushes)
- Step 3: Index a document - the version map won't add this version
value and won't prune the tombstone (previously it did)
- Step 4: Delete a document - this will return NOT_FOUND instead of
DELETED because of the stale delete tombstone
This failure is actually fixed by #29619 in which we never leave stale
delete tombstones
Closes#29626
Today the VersionMap does not clean up a stale delete tombstone if it
does not require safe access. However, in a very rare situation due to
concurrent refreshes, the safe-access flag may be flipped over then an
engine accidentally consult that stale delete tombstone.
This commit ensures to never leave stale delete tombstones in a version
map by always pruning delete tombstones when putting a new index entry
regardless of the value of the safe-access flag.
This commit remove serializing of common stats flags via its enum
ordinal and uses an explicit index defined on the enum. This is to
enable us to remove an unused flag (Suggest) without ruining the
ordering and thus breaking serialization.
We removed catched throwable from the code base and left behind was a
comment about catching InternalError in MemoryManagementMXBean. We are
not going to catch InternalError here as we expect that to be
fatal. This commit removes that stale comment.
The name of the bulk thread pool was renamed to "write" with "bulk" as a
fallback name. This change was made in 6.x for BWC reasons yet in 7.0.0
we are removing this fallback. This commit removes this fallback for the
write thread pool.
We grab all the NumberFieldMappers to determine the whitelist of allowed
number types, but `scaled_float` is in a module so it isn't picked up
automatically. This commit adds `scaled_float` to the whitelist
manually.

This commit allows license installation without TLS being enabled when
the cluster is in dev mode. The main difference this change enables is
the ability to install a production license on a single node cluster
that is bound to localhost and does not have the single-node discovery
enabled.

The SQL action supports several text outputs and used to default to an
output that looked like the SQL CLI. It is a lovely output format but
this changes output selection behavior to mimick Elasticsearch's
standard behavior: it'll now default to the same format as the request.
That means that if you want the pretty text format then you need to ask
for it. The way to do that is:
```
POST /_xpack/sql?format=text/plain
{
"query": "SELECT * FROM library ORDER BY page_count DESC LIMIT 5"
}
```

* Move sql-proto and jdbc to java.util.TimeZone
This moves sql-proto and jdbc from Joda's `DateTimeZone` to
`java.util.TimeZone`, this will allow us in the future to be able to decouple
JDBC from Joda.
This does not decouple all of SQL from joda, it focuses on as small a piece as I
could for sql-proto and jdbc.
Requires https://github.com/elastic/elasticsearch/pull/29487 to be merged first.

number) existing to the end of gradle's configuration phase, and based

Today when a version map does not require safe access, we will skip that
document. However, if the assertion is enabled, we remove the delete
tombstone of that document if existed. This side-effect may accidentally
hide bugs in which stale delete tombstone can be accessed.
This change ensures putAssertionMap not modify the tombstone maps.
This commit adds waits for two Netty threads that run in the background
and require explicit calls to await inactivity in them. This shows up
as an issue in security tests since we always use netty and do not have
these waits so these threads can trip the thread leak detector.
