Lars SchneiderMost Git developers work on Linux and they have no way to know if their changes would break the Git for Windows build. Let's fix that by adding a job to TravisCI that builds and tests Git on Windows. Unfortunately, TravisCI does not support Windows.
Therefore, we did the following: * Johannes Schindelin set up a Visual Studio Team Services build sponsored by Microsoft and made it accessible via an Azure Function that speaks a super-simple API. We made TravisCI use this API to trigger a build, wait until its completion, and print the build and test results. * A Windows build and test run takes up to 3h and TravisCI has a timeout after 50min for Open Source projects. Since the TravisCI job does not use heavy CPU/memory/etc. resources, the friendly TravisCI folks extended the job timeout for git/git to 3h.
Things, that would need to be done: * Someone with write access to https://travis-ci.org/git/git would need to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI repository setting [1]. Afterwards the build should just work.
Things, that might need to be done: * The Windows box can only process a single build at a time. A second Windows build would need to wait until the first finishes. This waiting time and the build time after the wait could exceed the 3h threshold. If this is a problem, then it is likely to happen every day as usually multiple branches are pushed at the same time (pu/next/ master/maint). I cannot test this as my TravisCI account has the 50min timeout. One solution could be to limit the number of concurrent TravisCI jobs [2].
