Summary: Test failure:
transient_replication_test.py::TestTransientReplicationRepairStreamEntireSSTable::test_optimized_primary_range_repair
Key: CASSANDRA-17685
URL: https://issues.apache.org/jira/browse/CASSANDRA-17685
Project: Cassandra
Issue Type: Bug
Components: Test/dtest/python
Reporter: Andres de la Peña
The Python dtest
{{transient_replication_test.py::TestTransientReplicationRepairStreamEntireSSTable::test_optimized_primary_range_repair}}
is flaky at least in {{{}cassandra-4.1{}}}, with a flakiness < 1%.
I haven't seen the failure on Jenkins but on [this CircleCI
run|https://app.circleci.com/pipelines/github/adelapena/cassandra/1663/workflows/c63703e3-8c7a-42c6-981a-53cb59babe1f/jobs/17476]
for CASSANDRA-17458.
The failure can also be [reproduced in the
multiplexer|https://app.circleci.com/pipelines/github/adelapena/cassandra/1666/workflows/6f925be1-c0df-4b2a-83e0-4612a46f32bd/jobs/17516],

There is an optional argument "input", allowing you to
pass a string to the subprocess's stdin. If you use this argument
you may not also use the Popen constructor's "stdin" argument, as
it will be used internally.
The other arguments are the same as for the Popen constructor.
If universal_newlines=True is passed, the "input" argument must be a
string and stdout/stderr in the returned object will be strings rather
than
bytes.
