@brettcannon: It looks to me like Travis built against an old version. Did I hit some sort of workflow bug?

I changed Doc/Makefile and pushed. This was local revision dc85bd9, which AFAICT was auto-merged on GitHub to revision 8163ffa44849 . This kicked off Travis CI build 7463 ( https://travis-ci.org/python/cpython/builds/254150043 ).

The build didn't work because I had to fix .travis.yaml too. So I pushed a second change, which on my side is revision a8f8d57 . That kicked off Travis CI build 7464 ( https://travis-ci.org/python/cpython/builds/254151401 ). But Travis build 7464 was run against 8163ffa44849 ! Both Travis builds 7463 and 7464 were based on the same revision.

What's strange is that on Travis's "requests" dashboard: https://travis-ci.org/python/cpython/requests
it shows the latest checkin comment for build 7464. But both builds were clearly based on the same revision. It even shows you that in the requests dashboard.

What's going on?

I may try to fool Travis into running another build by uploading a no-op revision.
