review: Needs Fixing (continuous-integration)

[Alan Griffiths (alan-griffiths)]

Using the old version seems like storing up problems for later.

/1/ We should have tests that validate the new versions.

/2/ While the old versions do need tests in this release, they are going to be deleted in 0.1.

I'd like to see corresponding tests covering both new and old APIs (and the latter tests can simply be deleted with the APIs).

review: Needs Information

[Cemil Azizoglu (cemil-azizoglu)]

I agree with Alan.

We need to port the instances where this API is used to the new way including the tests. In the process of doing that we'll eliminate the possibility of releasing something that isn't useful/useable. We won't know that until/unless we do the work ourselves.

Don't worry about the time too much. Let's do the right thing.
