      More python3 compatibility · b44f9c0d
      Kirill Smelkov authored
      @jerome, I was trying to make zodbtools work with Python3 and along that road picked some bits of your work from !12. At present the migration to Python3 is not complete, and even though now I have the answer to how handle strings in both python2/3 in compatible and reasonable way (I can share details if you are interested), I have to put that work on hold for some time and use https://pypi.org/project/pep3134 directly in wcfs tests, since getting all string details right, even after figuring on how to do it, will take time. Anyway the bits presented here should be ready for master and could be merged now. Could you please have a look?
      Thanks beforehand,

      dump, commit: Test for both non-empty and empty transaction extensions · 425e6656
      Kirill Smelkov authored
      Currently we exercise zodbdump and zodbcommit+zodbdump with non-empty
      extensions, which works if ZODB is patched for txn.extension_bytes
      support, but fails on pristine ZODB.
      Support for txn.extension_bytes cannot get into upstream ZODB for
      more than a year:
      and  even if it somehow will make it, it will likely be only in ZODB5,
      while we still care to support ZODB4 and ZODB3.
      Skipping zodbdump / zodbcommit tests, if a ZODB does not have
      txn.extension_bytes support, would result in significant reduction of
      zodbtools test coverage, because practically that is the current
      situation with all upstream ZODB{3,4,5}. Dropping test coverage for
      non-empty extensions is neither a good option.
      For those reason, let's rework the tests and test both zodbdump and
      zodbcommit with two scenarios:
      1. on a test database where transactions extensions are always empty.
         This should work on all ZODB irregardless of whether
         txn.extension_bytes patch is there or not.
      2. on a test database where transactions extensions are present.
         This should work if ZODB has txn.extension_bytes support, but if not,
         we can mark this case as xfail, since the failure is expected.
      This way we make the testsuite pass irregardless of whether
      txn.extension_bytes support is there, and we don't abandon dump/commit
      testing coverage.
