This ensures that any warning generated from compiling the docs is treated as
an error. Also, building the docs is now one of the steps performed in CI.
Switching from Travis CI to Github Actions made us switch from Ubuntu 16.04 to
20.04. This causes errors for users running older versions of Ubuntu. I don't
think we can support Ubuntu 16.04 anymore, as it has gone out of support, but
we can at least attempt to support 18.04.
For reference, the reported error seems to be:
[17871] Error loading Python lib '/tmp/_MEIa1GHWz/libpython3.6m.so.1.0':
dlopen: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29’ not found
(required by /tmp/_MEIa1GHWz/libpython3.6m.so.1.0)`
See: https://discuss.overhang.io/t/error-upgrading-from-v11-2-9-to-v11-2-10/1557
GitHub Actions now performs the following tasks:
- run tests on every PR
- sync with git.overhang.io on push
- build binary releases on tags
Travis.CI was completely removed from this repo.
