Subject [jira] [Updated] (LUCENE-2795) Genericize DirectIOLinuxDir -> UnixDir
Date Sun, 15 Jan 2012 12:37:40 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Varun Thacker updated LUCENE-2795:
----------------------------------

    Attachment: LUCENE-2795.patch

I updated the patch so that it applies cleanly with the current trunk revision.

{noformat}ant build-native-unix{noformat}  Comiles successfully on a 64 bit Ubuntu Linux machine
running kernel version 3.0.0-14-generic. 

{noformat}ant-DDirectory=NativeUnixDirectory test-core{noformat} 
Runs successfully.

Is more testing required before committing it?

> Today DirectIOLinuxDir is tricky/dangerous to use, because you only want to use it for
indexWriter and not IndexReader (searching).  It's a trap.
> But, once we do LUCENE-2793, we can make it fully general purpose because then a single
native Dir impl can be used.
> I'd also like to make it generic to other Unices, if we can, so that it becomes UnixDirectory.
