--------------------------------------
Summary: In some environments, code coverage produces an empty
report
Key: IMPALA-13279
URL: https://issues.apache.org/jira/browse/IMPALA-13279
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
On some environments used for automation, all the tests run with code coverage
enabled but the report at the end is empty. Impala is generating the necessary
gcno/gcda files on exit, so this seems to be a bug during report generation in
that environment. It works fine locally on my Ubuntu 20 development box, so
there is something special about the environment.
Testing with the latest version of gcovr (7.2) doesn't show the same issue, so
one path to fixing this is to upgrade to gcovr==7.2. gcovr 7.2 requires python
3.8, so it would involve switching to the toolchain 3.8 python rather than the
3.7 python.
