Subject [jira] [Commented] (LUCENE-6835) Directory.deleteFile should "own" retrying deletions on Windows
Date Wed, 03 Feb 2016 10:07:39 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130169#comment-15130169

Michael McCandless commented on LUCENE-6835:
--------------------------------------------

bq. All the SVN branches are in git, you know that, Mike (right?).

Woops, I did not know (remember? ;)) that.  Thank you for the reminder!

And thanks for the suggestions on naming branches ... I'll try to put jira-inspired branches
under "jira" in the future ... but I'm a little nervous to try renaming the current one.

> 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 ...
