Varun Thacker updated LUCENE-2795: ---------------------------------- Attachment: LUCENE-2795.patch Updated jdocs. createOutput switches between direct and normal. Added constructors NativeUnixIndexOutput/NativeUnixIndexInput which does not take buffersize and uses 256kb by default. Changed logic of using forcedbuffersize as suggested - It is only used in MERGE context rest of the times BII.buffersize I am still trying to figure out how to find out different kernel versions in this case. This is what I found out till now. Use the system("uname -r") call in the c program directly. Use a makefile. Still haven't figured out how to do so using cpptasks though. > Genericize DirectIOLinuxDir -> UnixDir > -------------------------------------- > > Key: LUCENE-2795 > URL: https://issues.apache.org/jira/browse/LUCENE-2795 > Project: Lucene - Java > Issue Type: Improvement > Components: core/store > Reporter: Michael McCandless > Assignee: Varun Thacker > Labels: gsoc2011, lucene-gsoc-11, mentor > Attachments: LUCENE-2795.patch, LUCENE-2795.patch, LUCENE-2795.patch, > LUCENE-2795.patch, LUCENE-2795.patch, LUCENE-2795.patch > > > 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. -- This message is automatically generated by JIRA.
