Now that we can parse Elasticsearch's standard error messages in the CLI
and JDBC client we can just let those standard error messages bubble out
of Elasticsearch rather than catch and encode them.
In a followup we can remove the encoding entirely.
Original commit: elastic/x-pack-elasticsearch@bad043b6f7
This teaches SQL to parse Elasticsearch's standard error responses
but doesn't change SQL to general Elasticsearch's standard error responses
in all cases. That can come in a followup. We do this parsing with
jackson-core, the same dependency Elasticsearch uses for parsing
json. We shade jackson-core in the JDBC driver so that users don't have to worry about
dependency clashes. We do not do so in the CLI because it is a standalone
application.
We get a few "bonus" changes along the way:
1. We save a copy operation. Before this change responses were spooled
into memory and then parsed. After this change they are parsed directly
from the response stream.
2. We had a few classes entirely to support the spooling operation that we
no longer need: `BytesArray`, `FastByteArrayInputStream`, and
`BasicByteArrayOutputStream`.
3. SQL's `Version` was incorrectly parsing the version from the jar manifest.
We didn't notice because the test was rigged to return `UNKNOWN` because
we *were* running the test from the compiled classes directory instead of the
jar. As part of shading jackson we moved running the tests to running against
the shaded jar. Now we can actually assert that we parse the version correctly.
It turns out we weren't. So I fixed it.

1. decouple JdbcDriver from other classes to not trigger static
initialization (this happens through JDBC service discovery)
2. reduce visibility of JdbcDriver#close so only on jar unloading it
gets triggered
3. mark 3 methods introduced in Jdbc 4.1 as unsupported (their semantics
are somewhat weird)
4. Move versioning info in one class
5. Hook Version class in both JDBC entry points to perform cp sanity
checks
6. Remove JdbcDataSource#close (DebugLog are closed when the Driver gets
unloaded by the DriverManager) as there can be multiple instances of DS
but only one for Driver known by the DriverManager
Replace Strings with constants
Properly set TZ in security tests as well
JdbcDataSource is more defensive with its internal properties
JdbcConfiguration password parameter is aligned with JDBC DriverManager
Remove usage of JdbcConnection API
Removed JdbcConnection#setTimeZone - this encourages folks to use our
private API which would tie us down.
It is somewhat limiting for folks but it has less downsides overall and
does not trip debugging (which adds a proxy unaware of this method).
Update docs
Add JdbcDataSource into the Jdbc suite

* Fix several NOCOMMITS
- renamed Assert to Check to make the intent clear
- clarify esMajor/Minor inside connection (thse are actually our own
methods, not part of JDBC API)
- wire pageTimeout into Cursor#nextPage

JodaTime timezone db can be out of date compared to that of the JDK which causes the JDBC Connection to fail when the randomized tests pick a timezone that's available in the JDK but not in Joda, like SystemV/PST8. This is happening because JdbcConnection configuration is using system default timezone and tries to pass it to Elasticsearch that is using joda. This commit, explicitly sets the time zone on JdbcConnection to a time zone randomly selected from a list of timezones that are known to both JDK and Joda.

The `net-client` project contained more then just the `net-client`.
It contains stuff like `SuppressForbidden` and `Strings` and `IOUtil`
and other things shared between the CLI and JDBC. It also does contain
the http client. Anyway, it makes more sense to call it `shared-client`,
I think.
Alos updated the copywrite dates on the files that I touched because
they are all 2017 files.
Removed some uses of `String.EMPTY` because they don't buy us anything
and require an extra import. `""` is just one less step.

move away from Properties
perform validation of settings names and values at startup
better exception handling
Original commit: elastic/x-pack-elasticsearch@d8a9edeccf

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

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...)

* Improve JDBC communication
Jdbc HTTP client uses only one url for messages and relies on / for ping
Fixed ES prefix being discarded (missing /)
Add HEAD handler for JDBC endpoint

The DriverManager registration is now public so the user can control it
(static block might not be enough). The checked exception is also
logged and the rest rethrown.
Fixed param type name to return the correct value
Original commit: elastic/x-pack-elasticsearch@026476a6e4
* 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.

Builds on elastic/x-pack-elasticsearch#2403 to move all of sql's integration testing into
qa modules with different running server configurations. The
big advantage of this is that it allows us to test the cli and
jdbc with security present.
Creating a project that depends on both cli and jdbc and the
server has some prickly jar hell issues because cli and jdbc
package their dependencies in the jar. This works around it
in a few days:
1. Include only a single copy of the JDBC dependencies with
careful gradle work.
2. Do not include the CLI on the classpath at all and instead
run it externally.
I say "run it externally" rather than "fork it" because Elasticsearch
tests aren't allowed to fork other processes. This is forbidden
by seccomp on linux and seatbelt on osx and cannot be explicitly
requested like additional security manager settings. So instead
of forking the CLI process directly the tests interact with a test
fixture that isn't bound by Elasticsearch's rules and *can* fork
it.
This forking of the CLI has a nice side effect: it forces us to
make sure that things like security and connection strings other
than `localhost:9200` work. The old test could and did work around
missing features like that. The new tests cannot so I added the
ability to set the connection string. Configuring usernames and
passwords was also not supported but I did not add support for
that, only created the failing test and marked it as `@AwaitsFix`.

* 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

* 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.

It is used for debugging tests and should be kept abstract or
else it violates the naming conventions. It violates the naming
conventions because we do not wish to run it with the normal build.

Remove some duplicated methods, add some templating plus logging of
ES resultset (for easier debugging)
Rename debug test for CSV plus add one for Sql spec

Most tests worked fine. The datetime tests are broken for some time
zones. The csv tests were broken because they accepted the default
fetch size which looks like it is broken.

Adds a test that shows *how* SQL fails to address an index with two types
to the full cluster restart tests. Because we're writing this code
against 7.0 don't actually execute the test, but we will execute it when
we merge to 6.x and it *should* work.
Original commit: elastic/x-pack-elasticsearch@b536e9a142
This adds support for field level security to SQL by creating a new type of flow for securing requests that look like sql requests. `AuthorizationService` verifies that the user can execute the request but doesn't check the indices in the request because they are not yet ready. Instead, it adds a `BiFunction` to the context that can be used to check permissions for an index while servicing the request. This allows requests to cooperatively secure themselves. SQL does this by implementing filtering on top of its `Catalog` abstraction and backing that filtering with security's filters. This minimizes the touch points between security and SQL.
Stuff I'd like to do in followups:
What doesn't work at all still:
1. `SHOW TABLES` is still totally unsecured
2. `DESCRIBE TABLE` is still totally unsecured
3. JDBC's metadata APIs are still totally unsecured
What kind of works but not well:
1. The audit trail doesn't show the index being authorized for SQL.
