Shai Erera updated LUCENE-1591:
-------------------------------
Attachment: LUCENE-1591.patch
I removed this test from WriteLineDocTaskTest, since it doesn't really belong
there. It tested that if WLDT created a bz2 file, an attempt to read it as
regular would fail. But reading is not part of WLDT's logic, and that test case
belongs (and already exists) in LDM test.
I'm tempted to say "this patch should be fine", but given the history of this
issue and the OS weird-ness I'm being careful :)

> bzip compression can aid the benchmark package by not requiring extracting
> bzip files (such as enwiki) in order to index them. The plan is to add a
> config parameter bzip.compression=true/false and in the relevant tasks either
> decompress the input file or compress the output file using the bzip streams.
> It will add a dependency on ant.jar which contains two classes similar to
> GZIPOutputStream and GZIPInputStream which compress/decompress files using
> the bzip algorithm.
> bzip is known to be superior in its compression performance to the gzip
> algorithm (~20% better compression), although it does the
> compression/decompression a bit slower.
> I wil post a patch which adds this parameter and implement it in
> LineDocMaker, EnwikiDocMaker and WriteLineDoc task. Maybe even add the
> capability to DocMaker or some of the super classes, so it can be inherited
> by all sub-classes.
