Cried victory too soon, I'm afraid.
I have:
- compiled python 2.7.12 with the zlib patch
- created a virtualenv with that version
- installed duplicity in the virtualenv, along with lockfile and boto
The zlib test now succeeds:
(duplicity-venv) root@eniac:~# python -c "import zlib;zlib.crc32('a'*(1<<31 -
1))"
(duplicity-venv) root@eniac:~# python -c "import zlib;zlib.crc32('a'*(1<<31))"
(duplicity-venv) root@eniac:~#
But duplicity still throws the OverFlowError during Incremental backup,
and it wasn't anywhere near a large file. The modules mentioned in the
Traceback are all in the duplicity dir, btw.
