Comment 3 Jason Dillaman 2016-08-31 23:18:34 UTC

A new 0.94.8 test case that verified a bug fix was executed against 0.94.5

Comment 4 Vasu Kulkarni 2016-08-31 23:31:49 UTC

Jason,

:( , well i knew this was for 94.5(not far from 94.8) but there are api's that skip execution if not valid for the current ceph version, so its confusing and also this test looks so valid.

I am not sure how we can solve this problem for downstream, its going to be one ref based on the release(hammer, jewel etc), unless downstream rcm provides full cloned ref of the build associated with the errata build.

Comment 5 Ken Dreyer (Red Hat) 2016-09-01 04:09:47 UTC

When we can automate more of the build process, we'll be able to have Jenkins tag every Brew build's -patches ref, which will give us a straightforward way to "git checkout" the patches for a particular build.

An alternative solution would be to unpack the build's SRPM and use the tests in there, since that will have the exact code.
