The fix from issue 14398 for >4GB inputs regressed the behaviour when compressing an empty string. Going by issue 853061 the expectation is this should work. The problem was noticed when using the updated Python 2.7 package in Ubuntu Raring caused test failures in the Bazaar suite: <https://bugs.launchpad.net/bzr/+bug/1090043> |

On trunk, both the compressor and the standalone function (which uses the compressor) are affected. The easiest fix is rearranging the logic in function shared between BZ2Compressor.compress and BZ2Compressor.flush so the exit on no remaining input for the former case happens before the library call. |

On 2.7 only the compress() function is affected, and the fix is much simpler. Just using BZ_FINISH when the input is less then 4GB is sufficient. |
