This prevents us from having to hack a fake schema together on the
second (and third and fourth, etc) page of results.

The CLI and JDBC were meant to share the same named xcontent registry
but the cli action didn't reuse it by mistake.
Original commit: elastic/x-pack-elasticsearch@6c9af5a22a
The `AbstractSqlServer` class was used when SQL's CLI and JDBC were
transport actions. They are REST layer concepts now and it is unused so
it should go.
Original commit: elastic/x-pack-elasticsearch@25ec699564
Fix the name of the action the SQL uses to lookup index information from
the cluster state. The old name was silly.
Original commit: elastic/x-pack-elasticsearch@805fb29662
Organizes the SQL translate action to match the way that x-pack has been
organizing new actions for a while. All of the pieces are put into the
same class file.
Original commit: elastic/x-pack-elasticsearch@def911c0ab
Adds docs for the REST API, translate API, the CLI, and JDBC.
Next we need to add more example queries and documentation for our
extensions.

* Remove usage of Settings inside SqlSettings
Also hook client timeouts to the backend
Set UTC as default timezone when using CSV
As the JVM timezone changes, make sure to pin it to UTC since this is what the results are computed against
Original commit: elastic/x-pack-elasticsearch@3e7aad8c1f
Moves joda time handling into DocValueExtractor, that's the only place where it occurs at the moment.
Original commit: elastic/x-pack-elasticsearch@205e82990a
Firstly, data in H2 is now stored in TIMESTAMP WITH TIME ZONE since H2
does not allow a global TZ to be set and picks the JVM TZ when a record
is read.
JdbcAssert is now aware of this allows TIMESTAMP with TZ == TIMESTAMP
Discovered a serious bug in DateTimeFunction - unfortunately date
histogram is not useful except for year since most extract functions
avoid ordering which a histogram preserves.
Thus most DTF are now terms aggs with scripting.
Improved a bug that caused duplicate functions to not be detected because
of aliasing.
Moved some datetime tests to CSV but the aggs tests now are in sync with
H2
Fixed bug that caused arithmetic on aggs to not be properly resolved by
splitting the processor definition tree to aggName (unresolved) and
aggPath (resolved)

We weren't returning errors correctly from the server
or catching them correctly in the CLI. This fixes that
and adds simple integration tests.
Original commit: elastic/x-pack-elasticsearch@259da0da6f
A JDBC driver should throw only checked SQLExceptions.
Introduce JdbcSQLException and fix some no-commits along the way.

Better handling of SQL exceptions (result of incorrect queries) vs
unexpected ones (engine failure, ES...)
Original commit: elastic/x-pack-elasticsearch@2698402cdb
This commit removes ThrowableConsumer, WrappingException, ActionUtils and ObjectUtils by replacing them with core equivalents when needed.
Original commit: elastic/x-pack-elasticsearch@5a68418a3d
We switched most of the commands to asynchronous mode, this commit removes the synchronous version of exec to prevent accidental use of it in the future.
Original commit: elastic/x-pack-elasticsearch@03d0a6350d
Right now if you run `gradle regen` on Windows you'll get `CRLF` line
endings on all the ANTLR generated files because we run
```
ant.fixcrlf(srcdir: outputPath) {
patternset(includes: 'SqlBase*.java')
}
```
The docs for fixcrlf say that the default line endings that it
corrects to is based on the OS:
https://ant.apache.org/manual/Tasks/fixcrlf.html
This change locks it to `LF`.
Original commit: elastic/x-pack-elasticsearch@4396729e04
`RowSetCursor` was just like `RowSet` only it had methods that allowed
you to scroll to the next page. We now use `RowSet#nextPageCursor` to
get the next page in a way that doesn't require us to store state on
the server. So we can remove `RowSetCursor` entirely now.
Original commit: elastic/x-pack-elasticsearch@6a4a1efb20
* Switch `ResultSet#getFetchSize` from returning the *requested*
fetch size to returning the size of the current page of results.
For scrolling searches without parent/child this'll match the
requested fetch size but for other things it won't. The nice thing
about this is that it lets us tell users a thing to look at if
they are wondering why they are using a bunch of memory.
* Remove all the entire JDBC action and implement it on the REST
layer instead.
* Create some code that can be shared between the cli and jdbc
actions to properly handle errors and request deserialization so
there isn't as much copy and paste between the two. This helps
because it calls out explicitly the places where they are different.
* I have not moved the CLI REST handle to shared code because
I think it'd be clearer to make that change in a followup PR.
* There is now no more need for constructs that allow iterating
all of the results in the same request. I have not removed these
because I feel that that cleanup is big enough to deserve its own
PR.

These wrap `DataInput` and `DataOutput` to add the protocol
version being serialized. This is similar to the mechanism
used by core and it has made adding and removing fields from
the serialization protocol fairly simple.
Original commit: elastic/x-pack-elasticsearch@90b3f1199a
* big refactor of Processor by introducing ProcessorDefinition an
immutable tree structure used for resolving multiple inputs across
folding (in particular for aggregations) which at runtime gets
translated into 'compiled' or small Processors
Add expression arithmetic, expression folding and type coercion
Folding
* for literals, scalars and inside the optimizer
Type validation happens per type hierarchy (numeric vs decimal) not type
Ceil/Floor/Round functions return long/int instead of double
ScalarFunction preserves ProcessorDefinition instead of functionId
Original commit: elastic/x-pack-elasticsearch@a703f8b455
Removes a few NOCOMMITs that are tracked other places and updates
a few with plans on how to work on them.
Original commit: elastic/x-pack-elasticsearch@8d1cfdf4ee
This renames that `write` and `read` methods in SQL to `writeTo` and
`readFrom` to line up with the names used in core. I don't have a
strong opinion whether or not any name is better than any other but
I figure there isn't a good reason for SQL to be different from the
rest of Elasticsearch.
Original commit: elastic/x-pack-elasticsearch@e5de9a4b81
* Move CLI to TransportSqlAction
* Moves REST endpoint from `/_cli` to `/_sql/cli`
* Removes the special purpose CLI transport action instead
implements the CLI entirely on the REST layer, delegating
all SQL stuff to the same action that backs the `/_sql` REST
API.
* Reworks "embedded testing mode" to use a `FilterClient` to
bounce capture the sql transport action and execute in embedded.
* Switches CLI formatting from consuming the entire response
to consuming just the first page of the response and returning
a `cursor` that can be used to read the next page. That read is
not yet implemented.
* Switch CLI formatting from the consuming the `RowSetCursor` to
consuming the `SqlResponse` object.
* Adds tests for CLI formatting.
* Support next page in the cli
* Rename cli's CommandRequest/CommandResponse to
QueryInitRequest/QueryInitResponse to line up with jdbc
* Implement QueryPageRequest/QueryPageResponse in cli
* Use `byte[]` to represent the cursor in the cli. Those bytes
mean something, but only to the server. The only reasonint that
the client does about them is "if length == 0 then there isn't a
next page."
* Pull common code from jdbc's QueryInitRequest, QueryPageRequest,
QueryInitResponse, and QueryPageResponse into the shared-proto
project
* By implication this switches jdbc's QueryPageRequest to using
the same cursor implementation as the cli
Original commit: elastic/x-pack-elasticsearch@193586f1ee
Instead of throwing and catching an exception for invalid
indices this returns *why* they are invalid in a convenient
object form that can be thrown as an exception when the index
is required or the entire index can be ignored when listing
indices.
Original commit: elastic/x-pack-elasticsearch@f45cbce647
This integrates SQL's metadata calls with security by creating
`SqlIndicesAction` and routing all of SQL's metadata calls through
it. Since it *does* know up from which indices it is working against
it can be an `IndicesRequest.Replaceable` and integrate with the
existing security infrastructure for filtering indices.
This request is implemented fairly similarly to the `GetIndexAction`
with the option to read from the master or from a local copy of
cluster state. Currently SQL forces it to run on the local copy
because the request doesn't properly support serialization. I'd
like to implement that in a followup.
