classes: add new retain class for retaining build results Add a fairly simple class to tar up the work directory on task failure to a configurable location - useful when the build environment is ephemeral (e.g. an autobuilder/build pipeline). The directories that are retained can be configured, and you can also choose to save directories on every build as well if desired.
[This is a significant reworking of a prototype I sent as an RFC back in 2020 (AKA "workdir_save"). Changes since then include deferring tarball creation until the end, more config flexibility, and the addition of test cases.] Changes since v1: * Use ;prefix= instead of : to specify tarball prefix, to be consistent with other similar usages and avoid potential confusion with overrides * Use prefix of "workdir" for default work directory tarballs * Fix dir name within tarball to not have .tar.gz extension * oe-selftest: fix test_retain_misc to be deterministic (should solve failures seen on the autobuilder) and tweak tests for robustness in a few places * oe-selftest: add detail to failure messages in test_retain_misc and test_retain_failure The following changes since commit 662396533177b72cc1d83e95841b27f7e42dcb20: create-spdx-3.0/populate_sdk_base: Add SDK_CLASSES inherit mechanism to fix tarball SPDX manifests (2024-07-26 12:26:24 +0100) are available in the git repository at: https://git.yoctoproject.org/poky-contrib paule/retain https://git.yoctoproject.org/poky-contrib/log/?h=paule/retain Paul Eggleton (1): classes: add new retain class for retaining build results meta/classes-global/retain.bbclass | 182 +++++++++++++++++++++++++ meta/lib/oeqa/selftest/cases/retain.py | 241 +++++++++++++++++++++++++++++++++ 2 files changed, 423 insertions(+) create mode 100644 meta/classes-global/retain.bbclass create mode 100644 meta/lib/oeqa/selftest/cases/retain.py -- 1.8.3.1
