YQL-21365: Fix TLangVerProxyNode::Clone

2026-07-03T12:55:10Z

#### Fix TLangVerProxyNode::Clone and add related test cases ✎ - Corrected the `Clone` method implementation to properly handle deep copying of inner nodes using `SafeClone`, ensuring correct node duplication behavior. - Introduced new test cases and canonical data to validate the functionality of `GROUP BY ROLLUP` with `NULLIF` and `COUNT(DISTINCT)` expressions. - Added corresponding test configuration and SQL format validation files to support the new test scenario.

YQL-20928: Fix RIGHT JOIN for YqlSelect

2026-04-30T19:49:20Z

Support `FULL JOIN` and fix `RIGHT JOIN` for `YqlSelect`. The problem with `RIGHT JOIN` is that in a situation, when we have `[a, b, c, d, e]` on a stack and are going to "perform" `right`, all of `[a, b, c, d, e]` are marked optional, because the `inputIndex` is equal to stack size. But we must mark only `[a, b, c, d]` as optionals. commit_hash:b78c5bcecba4b736475d3428918c2a3c377373bb

YQL-21046: Support window functions for YqlSelect

2026-04-28T11:53:09Z

This patch adds support for `RowNumber`, `CumeDist`, `NTile`, `Rank`, `DenseRank`, `PercentRank`, `Lead`, `Lag`, `FirstValue`, `LastValue` and `NthValue`. It gives +3 TPC-DS queries and +5 TPC-DS bugs unlocked. The callable `YqlWin` was introduces, having the following form: ```yqls (YqlWin 'function_name 'window_name '() # options (Void) # type slot ...) # args ``` During the callable type annotation and expansion the same code for implementation functions substitution is used and shared even with a pgSQL. There was an issue with a `listType` for `YqlAgg`, `YqlAggWin` and `YqlWin`, because it was built incorrectly by referencing an atom "row" instead of _that_ argument row. It is fixed with a new "type slot". Now it has 3 states: `(Void)`, which is set by translator just as a stub, `row` that is set by `YqlSetItemWrapper` during the `RebuildLambdaColumns`, so then on the `YqlWin` type annotation it can take this `row` and wrap it to the `listType`, pass to the function and call for a repetition, so in a next stage the `resultType` will be ready. commit_hash:256fc2cb359714a646a308359b340b1715919f5d

YQL-21046: Support window aggregation over YqlSelect

2026-04-20T08:22:28Z

Introduce `YqlAggWin` callable and adapt `PgWindow` as `YqlWindow`. The `YqlAggWin` is similar to `YqlAgg`, but with window reference (name) included. Moved `PgWindowWrapper` to `SqlWindowWrapper`. It gives +6 TPC-DS test cases. Window functions are not yet supported, because they have separate callables and an extra design is required. commit_hash:ccef4463fd994779da21514dc9f6f596c511bbfe
