Commit 0dbf3c44 by Kirill Smelkov

tox: v↑ everything

- start testing NEO with ZODB4 and ZODB5. ZODB4-*-NEO works while
  ZODB5-*-NEO currently fails [1].
- update NumPy to latest releases.
- update Python 3 to latest releases.

  • @jm, FYI, I've tried to run Wendelin.core tests with all ZODB versions, and while it works with ZODB{3,4}-ZEO, ZODB{3,4}-NEO and ZODB5-ZEO5, for ZODB5-NEO it stably breaks:

  • Can you test the 'zodb5' branch of NEO ?

  • @jm thanks for feedback. With zodb5 branch it looks better, but there is still 1 failure:

  • self.app should not be None: it seems that Storage.close was called unexpectedly. Can you add a breakpoint and get the traceback to see why it's called ?

  • @jm, I of course could do it, but maybe it makes more sense just to reproduce the issue on your side? The command to run tests is:

    $ WENDELIN_CORE_TEST_DB="<neo>" make test.py
    

    and initial environment is easy to prepare with virtualenvand pip in 3 - 5 minutes.

    Does the breakage reproduce on your side?

  • Ouch no. Too heavy for me. Fortunately, it was easy to reduce testing.py and test_zodb to something of ~70 lines. I tested by running the beginning of test_deactivate_btree 2 times, with your whole setup/teardown code around each call. If I also add print self, self.app at the beginning of Storage.lastTransaction, we see:

    Using temp directory '/tmp/neo_tests/1523904777.938541'.

    Traceback (most recent call last):

    Which means that it keeps using a Storage object of a previous test. Note also that before Review Connection/DB closure , we get the following traceback:

    Traceback (most recent call last):
      File "../zodb5/bin/python", line 41, in <module>

        self.newTransaction(transaction, False)
      File "ZODB/Connection.py", line 747, in newTransaction
        assert self._storage is None
    AssertionError
    

    About my question above, the storage is obviously closed by functional.NEOCluster itself. It's "luck" if it does not fail with other ZODB storages.

    I already suspected something wrong in the way you use ZODB. I suggest to close the DB explicitly in teardown.

  • If I also add print self, self.app at the beginning of Storage.lastTransaction

    (... and a print stor in TestDB_Base.dbopen)

  • Too heavy?? Anyway, you are right that connections from previous test could be left there alive, and since transaction keeps weak references to them and invoke at synchronization points (e.g. at transaction.commit()) this could lead to situations when connection tries to use closed storage.

    I've pushed up the following fixes: kirr/wendelin.core@5a5ed2c7, kirr/wendelin.core@01b995a4.
