Paul Elschot updated LUCENE-1410:
---------------------------------
Attachment: LUCENE-1410c.patch
The 1410c patch is much like the 1410b. It adds some bug fixes and code
cleanups and it includes a generator for java decompression classes. After
applying the patch, run the generator once in
src/java/org/apache/lucene/util/pfor :
python gendecompress.py
After that, in the trunk directory:
ant -Dtestcase=TestPFor test-core
should finish successfully in just over a minute, as it also includes
decompression performance tests.
To be done:
- possibly split the performance tests from the functional tests, this might
require adding an ant target for performance tests,
- possibly add byte padding to move exceptions to natural position,
- add performance tests for decompression with exception patching,
- switch decompression to relative buffer addressing (get() instead of
get(index)),
- optimize the exception decoding (i.e. patching) code,
- optimize the compression code,
- generate/correct the javadocs.
