* IntelliJ inspection and checkstyle rule for "Collection.EMPTY_* field accesses replaceable with Collections.empty*()"
* Reverted checkstyle rule
* Added tests to pass CI
* Codestyle
* ROUND and having comparators correctly handle doubles
Double.NaN, Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY are not real
numbers. Because of this, they can not be converted to BigDecimal and instead
throw a NumberFormatException.
This change adds support for calculations that produce these numbers either
for use in the `ROUND` function or the HavingSpecMetricComparator by not
attempting to convert the number to a BigDecimal.
The bug in ROUND was first introduced in #7224 where we added the ability to
round to any decimal place. This PR changes the behavior back to using
`Math.round` if we recognize a number that can not be converted to a
BigDecimal.
* Add tests and fix spellcheck
* update error message in ExpressionsTest
* Address comments
* fix up round for infinity
* round non numeric doubles returns a double
* fix spotbugs
* Update docs/misc/math-expr.md
* Update docs/querying/sql.md
* Remove LegacyDataSource.
Its purpose was to enable deserialization of strings into TableDataSources.
But we can do this more straightforwardly with Jackson annotations.
* Slight test improvement.
The parameters generator uses CompressionStrategy.noNoneValues() instead
of CompressionStrategyTest.compressionStrategies() which wrapped each
strategy in a single element array. This improves readability of the
test.

* Add REGEXP_LIKE, fix empty-pattern bug in REGEXP_EXTRACT.
- Add REGEXP_LIKE function that returns a boolean, and is useful in
WHERE clauses.
- Fix REGEXP_EXTRACT return type (should be nullable; causes incorrect
filter elision).
- Fix REGEXP_EXTRACT behavior for empty patterns: should always match
(previously, they threw errors).
- Improve error behavior when REGEXP_EXTRACT and REGEXP_LIKE are passed
non-literal patterns.
- Improve documentation of REGEXP_EXTRACT.

* Add tests to verify that buffers have been returned.
* Fix various Yielder leaks.

into an exception while accumulating the last value from the input
yielder.
- MergeSequence leaked input yielders from "toYielder" if it ran into
an exception while building the initial priority queue.
- ScanQueryRunnerFactory leaked the input yielder in its
"priorityQueueSortAndLimit" strategy if it ran into an exception
while scanning and sorting.
- YieldingSequenceBase.accumulate chomped IOExceptions thrown in
"accumulate" during yielder closing.
* Add tests.
* Fix braces.
* Refactor JoinFilterAnalyzer
This patch attempts to make it easier to follow the join filter analysis code
with the hope of making it easier to add rewrite optimizations in the future.
To keep the patch small and easy to review, this is the first of at least 2
patches that are planned.
This patch adds a builder to the Pre-Analysis, so that it is easier to
instantiate the preAnalysis. It also moves some of the filter normalization
code out to Fitlers with associated tests.
* fix tests
* Refactor JoinFilterAnalyzer - part 2
This change introduces the following components:
* RhsRewriteCandidates - a wrapper for a list of candidates and associated
functions to operate on the set of candidates.
* JoinableClauses - a wrapper for the list of JoinableClause that represent
a join condition and the associated functions to operate on the clauses.
* Equiconditions - a wrapper representing the equiconditions that are used
in the join condition.
And associated test changes.
This refactoring surfaced 2 bugs:
- Missing equals and hashcode implementation for RhsRewriteCandidate, thus
allowing potential duplicates in the rhs rewrite candidates
- Missing Filter#supportsRequiredColumnRewrite check in
analyzeJoinFilterClause, which could result in UnsupportedOperationException
being thrown by the filter
* fix compile error
* remove unused class
* Refactor JoinFilterAnalyzer - Correlations
Move the correlation related code out into it's own class so it's easier
to maintain.
Another patch should follow this one so that the query path uses the
correlation object instead of it's underlying maps.
* Optimize join queries where filter matches nothing
Fixes#9787
This PR changes the Joinable interface to return an Optional set of correlated
values for a column.
This allows the JoinFilterAnalyzer to differentiate between the case where the
column has no matching values and when the column could not find matching
values.
This PR chose not to distinguish between cases where correlated values could
not be computed because of a config that has this behavior disabled or because
of user error - like a column that could not be found. The reasoning was that
the latter is likely an error and the non filter pushdown path will surface the
error if it is.

* Fix off-by-one in IndexedTableJoinMatcher.getCardinality.

The missing value is the phantom null that can be generated by outer joins.
* Fix tests.
ApproximateHistogram - seems unlikely
SegmentAnalyzer - unclear if this is an actual issue
GenericIndexedWriter - unclear if this is an actual issue
IncrementalIndexRow and OnheapIncrementalIndex are non-issues becaus it's very
unlikely for the number of dims to be large enough to hit the overflow
condition

This change fixes a potential integer overflow in BufferArrayGrouper that
was flagged by LGTM. It also adds a check that the vectorized arrays are
initialized before aggregateVector is called.
The changes in HashTableUtils should not have any effect since the numbers
being multiplied are small, but the change will remove the warnings from
being flagged in LGTM.
