datetime interpretation changed

[Michael Nelson]

Sorry I haven't looked further, but we started seeing the following error recently, which seems to be related to the recent release of wadllib (note, the error is misleading, as it has skipped the expected date comparison, see further paste below):

Note: the test is itself expecting to find a datetime object in the api value - see line 21: (yes, we should be using python fixtures)

Since the new version of this library broke a number of things and since it appears this is not going to get fixed anytime soon, why don't "we" just revert the changes and upload a new version for Precise?

Has it been determined that this library is the root cause, and its
not a python2.7 fallout?

[Brad Figg (brad-figg)]

@robert,

According to comments to bug #929068, reverting to a previous version of this library "solved" the problem. Does that mean that this is the root cause. Seems likely, though without digging into the issue and finding the exact cause I wouldn't know.

Brad, Michael, I want to add this test into the wadllib set and wondered if you can paste or upload the test json and structure you guys were using for this?

[Launchpad Janitor (janitor)]

This bug was fixed in the package python-wadllib - 1.3.0-2

---------------
python-wadllib (1.3.0-2) unstable; urgency=low

  * Rebuild against python3-defaults 3.2.3~rc1-2, to generate correct
    ${python3:Depends}.
  * Patch no-et-roundtrip: Avoid round-trip through ET that loses namespaces.
    (LP: #924240)
  * Bump Standards-Version to 3.9.3, no changes needed.

Hi Richard - sorry for the delay (been sick). The json fixture that is
being used in the test results shown in the description above is:
