Varun Thacker updated LUCENE-2795:
----------------------------------
Attachment: LUCENE-2795.patch
Initial Patch..
This will apply to the IOContext branch. This patch also contains some
uncommitted code from LUCENE-2793.
In NativePosixUtil.cpp the open_direct method where I use fcntl() for OS X
could not be compiled on my machine because of the OS specific F_NOCACHE flag
used. Let me know if the usage is correct.
> Genericize DirectIOLinuxDir -> UnixDir

> 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.
