fornwall opened a new pull request, #4814: URL: https://github.com/apache/arrow-adbc/pull/4814
`Cursor.adbc_read_partition()` reads through `AdbcConnectionReadPartition` and the returned stream belongs to the connection, but the cursor cancelled its statement instead: both from the SIGINT handler around the blocking calls and from `Cursor.adbc_cancel()`. A driver with no active query on the statement treats that as a no-op, leaving the partition read running. Track the current cancel target on the cursor: the statement after _clear()/execute(), the connection after `adbc_read_partition()`. Use it for `adbc_cancel()`, the blocking partition read, and the row iterator that consumes the result stream. Fix the `AdbcStatement.cancel` docstring, which claimed to cancel the connection. Test against the Flight SQL test server, whose "forever" query blocks ReadPartition until the client cancels the connection. AI disclaimer: Created with codex and gpt-6 astra.
