marcuslin123 opened a new pull request, #59411:
URL: https://github.com/apache/spark/pull/59411
### What changes were proposed in this pull request?
This pull request adds the original Python callable, `func`, to the
`AbstractTranspiler._transpile_from_ast` hook and passes it through from
`_transpile_func`.
The built-in `CatalystTranspiler` signature and its direct test invocation
are updated to match.
A regression test registers an out-of-tree-style transpiler and verifies
that it receives the exact
callable object being transpiled.
### Why are the changes needed?
Out-of-tree transpilers may need the callable for capture extraction,
canonical source generation,
or fingerprinting. Today they must recover it by walking Python stack frames
and reading the `func`
local from `_transpile_func`. Passing the callable through the hook makes
that contract explicit and
removes the dependency on Spark's internal stack layout.
### Does this PR introduce _any_ user-facing change?
No. This changes an experimental internal transpiler extension hook.
### How was this patch tested?
Added `test_udf_transpiler_receives_original_callable` to
`pyspark.sql.tests.test_udf_transpile_unit`.
