Subject Re: still getting intermittent index error on linux
Date Sun, 22 Apr 2007 12:47:02 GMT
Hi Marcel - ok I can reproduce it on MacOSX, a few flavours of linux and
Windows XP - I am now working on a fix.

I have noted the main issues in the JIRA, but basically, its incorrect use
of createNewFile in File - according to the java specification, so I have
re-worked locks to use NIO (FileChannel and FileLock).

Now, what is confusing me is that locks are being requested for
*directories* that do not exist - not sure what to do in that case, and that
is causing failures (as it won't created the directory automatically).


A few pointers, and I should have a patch for this (testing is a bitch, but
its reproducible at least, just not in a junit test - you have to start up
and stop a lot of times to see this).
