Travis Notes for Administrators

Administrators: Are PRs taking > 1 hr to run through Travis? If you look at the Travis logs is it building riscv-tools?

This is because someone committed a PR to master which bumped riscv-tools and the master cache needs to be updated. This is the procedure to follow to get things fast again. We don't generally branch updates (e.g. to master), just PRs.

To get the master cache good again:

  1. Wait for the PR that is changing riscv-tools to go green.
  2. On Travis, click More Options -> Caches on the upper right.
  3. Click Delete for the master Cache.
  4. Click More Options->Settings
  5. On the General Settings section, switch the Build Branch Updates toggle to ON.
  6. Perform the PR's merge to master. This will cause the master cache to build riscv-tools.
  7. Once the merge commit goes green on Travis, switch the Build Branch Updates toggle to OFF.

For other PRs which were happening in parallel to the bump of riscv-tools:

If your PR already has a cache and you want to keep doing development with the old version of riscv-tools, no action is needed.

If you want to merge or rebase your PR on top of master with the new version of riscv-tools, you should delete your PR branch's local cache. Otherwise it will rebuild the branch cache instead of using master's cache. To do this:

  1. Wait for the previous steps to go through so that the master cache is done.
  2. On Travis, click More Options -> Caches on the upper right.
  3. Click Delete for your PR branch's cache.
  4. Push updates to the PR as usual, it should download the new master cache.
