* Pooled and buffered gzip implementation * Add test for gzip * Add integration test * Ensure lfs check within transaction The previous code made it possible for a race condition to occur whereby a LFSMetaObject could be checked into the database twice. We should check if the LFSMetaObject is within the database and insert it if not in one transaction. * Try to avoid primary key problem in postgres The integration tests are being affected by https://github.com/go-testfixtures/testfixtures/issues/39 if we set the primary key high enough, keep a count of this and remove at the end of each test we shouldn't be affected by this.
