I have set up continuous integration for my open source project at Travis. tox seems to be having some problems with quotes in the commands, so I set up a temporary branch for debugging the problem. At this point I am encountering a very strange issue.
The last 3 commits and their build status on Travis:
- Bla - build 32 passed
- eklzjfljkze - build 32 failed
- Revert "eklzjfljkze" - build 34 failed
As the last commit reverts the one that caused the failure, I see no reason why build 34 shouldn't pass. Perhaps Travis is caching some stuff, but Travis's Settings->Caching says "No caches have been created yet". As I'm using the free plan for open source projects, I don't think I can even enable caching.
From previous attempts, I have noticed that if I roll back the branch to the passing commit ('Bla') using git push --force, the build will pass again.
All of these commits work fine locally using the same python and tox versions.
What's going on?
EDIT Now it's failing in a simular way. Compare builds 36 and 37. The commit in build 37 only makes a change to the README, so it doesn't affect the build in any way. There must be some kind of conflict with Travis and Tox.
