The IndexPrivilegeTests have been notoriously slow for years.
@polyfractal identified the primary issue, which is that these tests
were running against an internal cluster with 1 or 2 data nodes and had
the number of replicas set to 1 for indices by default and the methods
in the test would perform a wait for green. This wait for green would
take the full thirty seconds when there was a single data node as the
index could never reach green health due to an unassigned replica. This
could have been caught earlier by asserting the request did not timeout
but this assertion was not present.
This change does a few things to address the issues above. The first is
that these tests now extend SecuritySingleNodeTestCase, which is a new
class that extends ESSingleNodeTestCase and contains the necessary
logic for the setup and teardown of security; much of which is based
off of SecurityIntegTestCase. This means that these tests always run
against a single node cluster and have a much simpler setup. The
default index template for these tests applies settings so that indices
are created with a single shard and no replicas.
Assertions have been added to ensure the health checks with a wait for
green status have not timed out. A handcoded wait for snapshots to
finish has been replaced with an assertBusy call. Finally, the BadApple
annotation has been removed from the test.

This changes JDBC so it can be released. It bundles the
`sql-shared-client` and `sql-proto` jars into the jar for the jdbc client.
It also Generates a pom for the jdbc driver when you run `gradle assemble`
on it. This will allow us to release the jdbc driver.
It also adds a zip distribution of the jdbc driver with all of its
dependencies bundled in the zip. It'd be nice to bundle all of the jdbc
driver's dependencies in the jar but we can't quite do that yet. So, for
now, to help folks using BI tools use the JDBC driver, we build a zip.

Rewrote the GROUP BY to use composite aggregation instead of terms
(and everything that comes with it) but instead rely on composite aggregation
This not only works better but simplifies the code complexity since
composite is a straight, two-level tree:
1. root/group-by/composite-keys
2. (metric) aggregations
This removes a lot of complexity from all stages that involve creating,
assembling and especially parsing the results.
By moving to composite agg, the aggregation/GROUP BY are now pageable
so the consumer/listener had to be extended to include a dedicated
cursor and specific (bucket) extractors inline with the scroll requests.
While at it, also improved the support for implicit GROUP BY by
formalizing it (previously it supported only counts and no other
agg).
In addition:
Fixed a JDBC bug that caused incorrect timeout to be passed
Improved the returned RowSet a bit and add better naming
Pick up @Nullable move from core
Make sure to specify the TimeZone for DateTimeHistogram extraction
Add missing javadoc
To avoid delegating NamedWriteableRegistry (NWR) and to keep the scope
clean, SQL writeables now handle their own serialization, keeping the
boundary between the Elasticsearch's NWR in place.
Pass NamedWriteableRegistry only when looking at the next page
To keep in line with the existing patter and simplify the code
bureaucracy, the deserialization happens directly.
Since the SearchSourceBuilder deserialization happens explicitly (and
it's otherwise opaque), the declarative invocation isn't necessary
anymore.
Add a bit more randomization in tests
Original commit: elastic/x-pack-elasticsearch@f5af046386
Currently numDocs() is computed lazily, but this doesn't help since
BaseCompositeReader calls numDocs() on its sub readers eagerly. This may cause
performance issues since every time we wrap a reader with DocumentSubSetReader
(which means for every query when DLS is enabled) we need to recompute the
number of live documents, which runs in linear time with the number of matches
of the role query.
Not computing numDocs() eagerly in DocumentSubSetReader might help, but it
would also be fragile since callers of this method still usually assume that
it runs in constant time. So I am proposing that we add a cache of the number
of live docs in order to decrease the performance hit of document-level
security. I would expect this cache to be efficient as it will not only reuse
entries in-between refreshes, but also across refreshes for segments that
haven't received any new updates.

With the change of requiring to configure account settings properly by
using affix settings, we forgot another special snowflake, namely the
configuration of mail properties, which can be arbitrary in the
configuration. Those properties are used when an email is sent.
This commit adds a few (but not all of those) options back and removes
the link in the documentation to refer to all of those settings.
Some settings are useless, as they only change the execution
expectations when a mail is sent, which the watch has control over.
The following settings are supported
* smtp.{host,port,user,password}
* smtp.auth
* smtp.starttls.{enable,required}
* smtp.{timeout,connection_timeout,write_timeout}
* smtp.{local_address,local_port}
* smtp.send_partial
* smtp.wait_on_quit

Adds `value_count` as one of the accepted metrics. The caveat is that
it only accepts numeric values for two reasons:
- Job validation at creation makes sure all metrics are numeric fields.
Changing this would require new syntax (or disallowing anything but
value_count on mixed fields)
- when `toBuilders()` is called, we have to supply a ValueSource to
the ValueCountBuilder, and we don't know what the field type is at that
time.
These are both fixable, but relatively more involved. I think numeric-only
is a reasonable limitation to start with

We specify an alias for signing key, but when we just have
a single key in key store this is an additional setting which
is annoying. This PR addresses this issue by making it optional.
- Changes in SamlRealmSettings to make signing/encryption
key alias optional
- Checks if none of the keys are useful for given operation
signing or encryption throws an error.
- Checks for no of aliases in key-store, if more than one and alias
is not specified throws error.
- If an alias is not specified and there is just one alias in
keystore then use it as the credential.
- Unit Tests
Note: A side effect of this change the above-mentioned behavior is
it's also applicable for encryption keys currently, but it is going
to change when fixing elastic/x-pack-elasticsearch#3980 for supporting multiple encryption keys.

The computed field contained a list of all aggs that were computed
for this particular rollup doc. It was used to help filter to the
correct rollup job/set of jobs.
But this functionality was never perfect, and has been obsoleted by
validating the rollup caps while searching. So we can remove the
computed field and save a bunch of space (since they were quite bulky)

This commit changes the combination of multiple automatons representing
a pattern so that the result of each step is minimal. Previously, the
code unioned the automata and performed the minimization operation
after all of the automata had been combined. This resulted in patterns
with lots of overlap causing a TooComplexToDeterminizeException even
though the end result could be a automaton that is total. Minimizing
the automata as we go, allows us to build an automata that could not
previously be built at the cost of additional operations. Automata are
typically cached in the security code, so the net performance impact
should be minimal.

This commit fixes several issues with the current implementation of
starting & stopping watcher
1. The WatcherServiceResponse was always returning a message, that the
request was acknowledged, completely independent from the fact if it was
or not.
2. A new cluster state instance was always returned, regardless if the
state had changed or not (which is explicitely mentioned in the
javadocs to check for this)
3. The AckedClusterStateUpdateTask now returns a proper WatcherServiceResponse
4. A failure now gets logged

Original commit: elastic/x-pack-elasticsearch@f4c1749f95
This PR adds logic to ensure that the fields (and field types) configured
in the Rollup Job are present in the index/indices specified by the job's
index pattern. If a field is missing, or is not aggregatable, it
will throw an exception before the job is created.
This is important for user-friendliness, because otherwise the user
only discovers an issue with mapping when the job is started and
fails to rollup correctly (and only really noticeable by looking at logs,
since it's a runtime failure).

When a watch is acknowledged, while it is also being executed, the
acknowledgment information can get lost. The reason for this is the
fact, that the execution writes the watch status inside of the watch
regardless, if other writes happened inbetween to make sure the
execution state is caught.
This commit checks the current executions in the execution service and
aborts the API call, if the specified watch ID can be found in those.
Note, this does not prevent this issue fully, as a watch could be
triggered, while the acknowledgement update is running, but it does
reduce the surface area of this problem. In order to properly solve
this, indexing the watch status as part of a watch would need to be
changed.

to add a 'watch' field.

This removes the `assert` that has been causing some very unexpected test
failures due to unexpected threading issues.
Some of the code changed and became async, so it is no longer guaranteed
that the same thread calls `doFlush` and `doClose`. We could similarly
make the field `volatile`, but since this `assert` is not really helping
anything it's easier to remove it.

If a job is deleted and then GetJobs API is immediately called,
it is possible for a job to be returned in the response. This is likely
due to the GetJobs API being executed on a node with a slightly
stale cluster state which shows the job as still existing.
So we delegate to the master node so the list of jobs/tasks is current.
After routing to the master, we need to check if the rollup job
is in the PersistentTask's CS. A job can be acknowledged canceled,
removed from the CS, but the allocated task is still alive. So we
first check the CS to make sure it's really there before going to the
allocated task to get the status.
As extra precaution, when running local to the task, we also make
sure the task isn't canceled before including it in the response.

All ML objects stored in internal indices are currently parsed
strictly. This means unknown fields lead to parsing failures.
In turn, this means we cannot add new fields in any of those
objects (e.g. bucket, record, calendar, etc.) as it is not
backwards compatible.
This commit changes this by introducing lenient parsing when
it comes to reading those objects from the internal indices.
Note we still use strict parsing for the objects we read from
the c++ process, which is nice as it guarantees we would detect
if any of the fields were renamed on one side but not the other.
Also note that even though this is going in from 6.3, we cannot
introduce new fields until 7.0.

If a user has roles that grant access to a large number of disparate
index patterns, then the resulting Automaton can become large and
too costly to determinise. This happens rarely, and is usually a sign
of a poorly implemented security model, so we have no immediate plans
to change the implementation. However the resulting error message is
not clear and does not provide sufficient information for users to
resolve the underlying problem.
This commit catches the underlying exception and provides a more
specific error message, with DEBUG logging of the offending index
patterns.

`doSaveState` can be invoked on different types of failure. Some of
these failures are recoverable (e.g. search exception) which just cause
the job to reset until the next trigger time. Other exceptions might
be caused by an Abort request.
Previously `doSaveState` assumed that the indexer state would be
INDEXING, STOPPED or STARTED and asserted that. But if we are ABORTING
it failed the assertion, and in production would try to persist
that aborting state which is not needed (and may complicate matters later).
This commit removes the assertion and only tries to persist if we
are not aborting. If we're aborting, we just invoke the next handler
which is likely an onFailure handler.

While it makes sense to apply auto-chunking in order to limit
the time range of the search for previewing datafeeds without aggs,
the same is not the case when aggs are used. In contrary, we should
do the preview the same way it would be if the datafeed run, as this
can reveal problems with regard to the datafeed configuration.
In addition, by default datafeeds with aggs have a manual chunking config
that limits the cost of each search. So, setting the chunking to auto
in those cases may lead to the datafeed preview failing even though
actually running the datafeed would work fine.
