------------------------------------------
Summary: Directory.deleteFile should "own" retrying deletions on
Windows
Key: LUCENE-6835
URL: https://issues.apache.org/jira/browse/LUCENE-6835
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Fix For: Trunk, 5.4
Rob's idea:
Today, we have hairy logic in IndexFileDeleter to deal with Windows file
systems that cannot delete still open files.
And with LUCENE-6829, where OfflineSorter now must deal with the situation too
... I worked around it by fixing all tests to disable the virus checker.
I think it makes more sense to push this "platform specific problem" lower in
the stack, into Directory? I.e., its deleteFile method would catch the access
denied, and then retry the deletion later. Then we could re-enable virus
checker on all these tests, simplify IndexFileDeleter, etc.
Maybe in the future we could further push this down, into WindowsDirectory,
and fix FSDirectory.open to return WindowsDirectory on windows ...
