potiuk opened a new pull request, #37916:
URL: https://github.com/apache/airflow/pull/37916
Some of the operators in Apache Beam had side effect that they modified
detault options passed to it in constructor, and in case of xdist tests it had
side effect that they could impact other test results (this happened recently
in main). The default options are already set by the Dataflow mixin in execute
method in all Beam operators, but in Python and Go operator the defaults are
also set in the constructor.
Setting the defaults in mixin uses deepcopy to avoid such side effects.
This might be intended, so this PR rather than removing default settings in
the constructor, also adds deepcopy in them and fixes resulting tests -
removing the defaults in tests that do not have the defaults set in the
constructor.
