The recent evaluation is sadly less victorious. > The latest iteration failed en masse due to network timeouts between > build farm nodes. Yes, I described this issue here: https://issues.guix.gnu.org/48468 and hopefully fixed it with https://issues.guix.gnu.org/48556. I need to perform a reconfigure / deploy but I'm waiting to have a few days ahead of me to fix potential issues. > It lets us see that the Audacity build is not attempted due to the > failure of wxwidgets. And in turn, the failure of webkitgtk and libsoup. > However, there is no information (logs, duration) available about those > failed builds. When a build is cancelled ("Cancel pending builds" button), all its dependents are automatically updated to "Failed dependency". It looks like this is the case for https://ci.guix.gnu.org/build/515005/details. > What can we do to clear all these "spurious" build failures and re-try > building the branch? I already tried using the "restart all builds" > button, but there were still a lot of spurious failures. I think the easiest way to recover from this situation is to remove the ungrafting specification and recreate it. It ensures that no build will fail because of previously failing/cancelled build dependencies. Note that when a build B is restarted in Cuirass ("Restart" button), any other build B' depending from B, will automatically be restarted if B becomes successful and all the other dependencies of B' are already successful. I used this mechanism to restart a few builds failing on the master branch because of substitutes timeout. I hope that when the keep-alive patchset will solve this situation. Thanks, Mathieu
