* classes: add new retain class for retaining build resultsPaul Eggleton2024-08-031-0/+182
If you are running your builds inside an environment where you don't have access to the build tree (e.g. an autobuilder where you can only download final artifacts such as images), then debugging build failures can be difficult - you can't examine log files, the source tree or output files. When enabled, by default this class will retain the work directory for any recipe that has a task failure in the form of a tarball, and can also be configured to save other directories on failure or always. It puts these tarballs in a configurable location (${TMPDIR}/retained by default), where they can be picked up by a separate process and made available as downloadable artifacts.
