How to prevent travis jobs after each commit?

Question

I am developing a library on github that has travis checks attached to it. I'd like to have a WIP pull request open to discuss ideas easily. There is a lot of tests set up for the project on travis, so I'd like to not trigger the tests every time I push a commit (to prevent server for being overloaded), as the code is not expected to pass anyway.

Is there a way I could do this on github without having access to travis configuration?

Answer 1

To skip builds on a per-commit basis you can add [ci skip] to the commit message, as described in the Docs, for example:

Before: Add blerb.
After:
Add blerb [ci skip]

To skip all non-PR builds, you can early-exit if the TRAVIS_PULL_REQUEST environnment variable is set to "false" fron your .travis.yml:

before_install:  # Earliest build step
  - if [ "$TRAVIS_PULL_REQUEST" == "false" ]; then echo "Not a PR, skipping" && exit; fi

Answer 2

My approach is to use an alias that I defined that appends the [ci skip] to each commit message of the current branch.

wip = "!f() { git filter-branch -f --msg-filter 'sed -e "\"s/$/ \\[ci skip\\]/g\""' ${1-master}..HEAD ; }; f"
unwip = "!f() { git filter-branch -f --msg-filter 'sed -e "\"s/ \\[ci skip\\]//g\""' ${1-master}..HEAD ; }; f"
wpush = "!f() { git wip $1 && git fpush && git unwip $1 ; }; f"

So basically what I do is simply git wpush.
