Uwe Schindler commented on LUCENE-4209:
---------------------------------------
This one fixes on windows, too.
We should commit this now to make my machines happy and open another issue to
make this horrible random file placement configureable like in your original
Sorter (taking Directory instead of File.createTempFile()). We must put this
method on the forbidden
list!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
damn!!!!!!

> The pattern "RefSorter-" I found in Lucene's source code, so it must come
> from tests. Why are they not cleaned up and why do we need those files? Would
> a RamDirectory not be enough for this?
> This is serious, as the files are never cleaned up, they stay alive when the
> test passes, so its not caused by the always failing Solr Suggester tests.
> There are also other filenames with .sorted and similar at end.
> The slave was taken automatically offline after its RAM-based /tmp (2 GB) was
> filling in <24h). On the Windows Box c:\Users\JenkinsSlave\AppData\Temp
> contained already 60,000 files like this (still deleting them), taking 12 GB
> of disk space. I will review Apache Jenkins, too -> also cleaned up lots of
> files.
