Subject [jira] Updated: (LUCENE-2598) allow tests to use different Directory impls
Date Sun, 22 Aug 2010 23:54:17 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2598?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Robert Muir updated LUCENE-2598:
--------------------------------

    Attachment: LUCENE-2598.patch

attached is a patch (currently has a few problems) to switch the functionality of MockRAMDirectory
into MockDirectoryWrapper.

before applying i did the following svn moves (renames) under test/o.a.l.store/
MockRAMDirectory -> MockDirectoryWrapper
MockRAMInputStream -> MockIndexInputWrapper
MockRAMOutputStream -> MockIndexOutputWrapper

i think somehow i screwed up the disk full stuff or similar, as most tests pass but just the
ones that simulate crashes dont work correctly with newDirectory implemented as new MockDIrectoryWrapper(new
RAMDirectory()) 

if we can fix this stuff, we can switch in other impls too.

> Now that all tests use MockRAMDirectory instead of RAMDirectory, they are all picky like
windows and force our tests to
> close readers etc before closing the directory.
> I think we should do the following:
> # change new MockRAMDIrectory() in tests to .newDirectory(random)
> # LuceneTestCase[J4] tracks if all dirs are closed at tearDown and also cleans up temp
dirs like solr.
> # factor out the Mockish stuff from MockRAMDirectory into MockDirectoryWrapper
> # allow a -Dtests.directoryImpl or simpler to specify the default Directory to use for
tests: default being "random"
> i think theres a chance we might find some bugs that havent yet surfaced because they
are easier to trigger with FSDir
> Furthermore, this would be beneficial to Directory-implementors as they could run the
entire testsuite against their Directory impl, just like codec-implementors can do now.
