What

A local IndexQuery (setLocal(true)) on a cache that is not in keep-binary mode now returns deserialized keys and values, the same as the distributed query. Queries through withKeepBinary() still return BinaryObjects.

Why

IndexQueryProcessor#queryLocal always returns rows in binary form. On the distributed path, the query future converts them using the query's keepBinary flag (GridCacheQueryFutureAdapter#unwrapIfNeeded). The local path (GridCacheQueryManager#indexQueryLocal) skipped that step, so a typed read of a local result failed with ClassCastException. It was reported on the dev list.

The fix applies the same unwrapBinaryIfNeeded(..., qry.keepBinary(), ...) call in indexQueryLocal. IndexQueryProcessor is not changed, because it also serves the remote side of distributed queries.

Compatibility: code that reads local results of a non-keep-binary cache as BinaryObject will now get the cache's own classes. Such code can use withKeepBinary(), which keeps the binary form.

Note: this touches the same method as #13735 (IGNITE-29191), so whichever is merged second needs a small rebase.

Tests

New tests in IndexQueryLocalTest:

• testLocalQueryReturnsDeserializedValues: a local query on a non-keep-binary cache returns Person values. It fails without the fix (the values are BinaryObjects).
• testLocalQueryKeepBinaryReturnsBinaryValues: a local query through withKeepBinary() still returns BinaryObjects.
