BaseTestCase.runBare fails to copy the database because it is in flux
---------------------------------------------------------------------
Key: DERBY-5290
URL: https://issues.apache.org/jira/browse/DERBY-5290
Project: Derby
Issue Type: Bug
Components: Test
Affects Versions: 10.9.0.0
Reporter: Kristian Waagan
Priority: Minor
If a JUnit assertion is raised, and the test causes the database used to be in
flux, the code to copy the database to the fail-directory may fail.
A reason for the database to change on disk may be that a checkpoint has been
triggered. I've seen cases where the copy failed when copying log files and
stub data files.
Potential fix components:
o wait to let the database stabilize
o delete copy on disk if the copy-operation fails
o delete copy on disk and retry (after a slight pause) if the copy-operation
fails
o ignore copy-errors, but write a warning-file to disk?
Example stack trace from a JUnit run:
..F...F.java.io.FileNotFoundException: system/wombat/seg0/d4d0.dat (No such
