The `-` and `+` as a number literal prefix are already
parsed by the rule in `valueExpression`. To accommodate
this, there are some code changes that enables the
`ExpressionBuilder` to parse Literal integers and decimals
together with the `-/+` prefix sign (if exists) and validate
them (wrong format, large numbers, etc.).
Follows: #33854
Previously, parsing an arithmetic expression with `*` and no spaces,
e.g.: `2*i` threw a parsing exception as the grammar rule for
tableIdentifier was clashing with the rule for arithmetic operator `*`.
This issue comes already in the lexer and the left part of the
expression (in our example `2*`) was recognised as a
TABLE_IDENTIFIER token.
The solution adopted is to allow the `*` wildcard in the table name
only if it's surrounded with double quotes, e.g.: `"my*index"`
Closes: #33957
Remove CamelCase to CAMEL_CASE conversion when resolving
a function. Only convert user input to upper case and then
try to match with aliases or primary names.
Keep the internal conversion FunctionName to FUNCTION__NAME
which provides flexibility when registering functions by their class
name.
Fixes: #34114
Fixes the equals and hash function to ignore the order of aggregations to ensure equality after serialization
and deserialization. This ensures storing configs with aggregation works properly.
This also addresses a potential issue in caching when the same query contains aggregations but in
different order. 1st it will not hit in the cache, 2nd cache objects which shall be equal might end up twice in
the cache.
Centralize and simplify the script generation between operators and functions which are currently decoupled. As part of this process most predicates (<, <=, etc...) were made ScalarFunction as their purpose and functionality is quite similar (see % and MOD functions).
Renamed ProcessDefinition to Pipe
Add ScriptWeaver as a mixin-in interface for script customization
Add logic for equals/lte/lt
Improve BinaryOperator/expression toString
Minimize duplication across string functions
Close#33975
This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
Implement circuit breaker logic in the parser which catches expressions
that can blow up the tree and result in StackOverflowError being thrown.

Two issues are resolved:
1. The `value_type` should be either long or double in case of numeric.
2. The key label for the aggregate filter (having) was duplicate of an aggr key label.
Fixes: #33520
* Added TRUNCATE function, modified ROUND to accept two parameters instead of one. Made the second parameter optional for both functions.
* Added documentation for both functions.
Removed rules in the grammar that were superfluous, as they
are already "caught" other rules in the same context.
Also switched to exact ambig detection for debug mode
Fixes: #31885
Previously multiple comma separated lists of options where not
recognized correctly which resulted in only the last of them
to be taked into account, e.g.:
For the following query:
SELECT * FROM test WHERE QUERY('search', 'default_field=foo', 'default_operator=and')"
only the `default_operator=and` was finally passed to the ES query.
Fixes: #32602
DAYNAME and MONTHNAME functions tests will be skipped if the right JVM parameter (-Djava.locale.providers=COMPAT) is not used in unit testing environment
Previously, when an non-pruned cast (casting as a different
data type) got applied on a table column in the `SELECT` clause,
the name of the result column didn't contain the target data type
of the cast, e.g.:
SELECT CAST(MAX(salary) AS DOUBLE) FROM "test_emp"
returned as column name:
CAST(MAX(salary))
instead of:
CAST(MAX(salary) AS DOUBLE)
Closes#33571
* Added more tests for trivial casts that are pruned
* SQL: Make Literal a NamedExpression
Literal now is a NamedExpression reducing the need for Aliases for
folded expressions leading to simpler optimization rules.
Fix#33523
Previously, when an arithmetic function got applied on a
table column in the `SELECT` clause, the name of the result
column contained weird characters used internally when
processing the SQL statement e.g.:
SELECT CHAR(emp_no % 10000) FROM "test_emp"
returned:
CHAR((emp_no{f}#14) % 10000))
as the column name instead of:
CHAR((emp_no) % 10000))
Also, fix an issue that causes a ClassCastException to be thrown
when using functions where both arguments are literals.
Closes#31869Closes#33461
* LeafCollector.setScorer() now takes a Scorable
* Scorers may not have null Weights
* IndexWriter.getFlushingBytes() reports how much memory is being used by IW threads writing to disk
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
Extend SHOW TABLES, DESCRIBE and SHOW COLUMNS to support table
identifiers not just SQL LIKE pattern.
This allows both Elasticsearch-style multi-index patterns and SQL LIKE.
To disambiguate between the two (as the " vs ' can be easy to miss),
the grammar now requires LIKE keyword as a prefix for all LIKE-like
patterns.
Also added some docs comparing the two types of patterns.
Fix#33294
* Tests for JdbcResultSet
* Added VARCHAR conversion for different types
* Made error messages consistent: they now contain both the type that fails to be converted and the value itself
Exclude classes meant for newer versions than what we are auditing against, those classes won't be found. There's no reason to exclude JDK classes from newer versions, with this PR, we will not extract them in the first place.
The new implementation is functional equivalent with the old, ant based one.
It parses task standard error to get the missing classes and violations in the same way.
I considered re-using ForbiddenApisCliTask but Gradle makes it hard to build inheritance with tasks that have task actions , since the order of the task actions can't be controlled.
This inheritance isn't dully desired either as the third party audit task is much more opinionated and we don't want to expose some of the configuration.
We could probably extract a common base class without any task actions, but probably more trouble than it's worth.
Closes#31715
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```
The incorrect NodeInfo is created when the optional parameter is not used, leading to the incorrect constructor being used. Simplified LocateFunctionProcessorDefinition by using one constructor instead of two.
Fixes https://github.com/elastic/elasticsearch/issues/32554
Skip the comparative tests using lowercasing/uppercasing against H2 (which considers the Locale).
ES-SQL is, so far, ignoring the Locale.
Still, the same queries are executed against ES-SQL alone and results asserted to be correct.
