Remove the code related to skipping CI runs if the tree was successfully tested before. With the GitHub CI this is done with the "ci-config" step, see e76eec35540 (ci: allow per-branch config for GitHub Actions, 2020-05-07) and 7d78d5fc1a9 (ci: skip GitHub workflow runs for already-tested commits/trees, 2020-10-08). This code hasn't been used since 4a6e4b96026 (CI: remove Travis CI support, 2021-11-23), and before that for the retired Azure pipeline support removed in 6081d3898fe (ci: retire the Azure Pipelines definition, 2020-04-11). This change is needed because this and subsequent commits are turning "ci/lib.sh" into a dumber library that'll only be tasked with setting variables for CI jobs, or for specific steps within those jobs. Now we don't need to worry about it potentially skipping the run on its own. This change also removes a subtle potential logic error introduced in 0e7696c64db (ci: disallow directional formatting, 2021-11-04). The "ci/check-directional-formatting.bash" script would have been made to run after the "save_good_tree" in invoked in "ci/run-static-analysis.sh". So if e.g. the "make coccicheck" failed we'd still mark the tree as good. I.e. the addition of "ci/check-directional-formatting.bash" didn't take into account that the various users of the "save_good_tree" function in ci/*.sh made a hard assumption that they're the only ci/*.sh script that's being run (and they use "set -e"). This is entirely academic since we weren't actually running this code, but is something to be careful of if anyone ever needs to resurrect parts of this. Finally, the cache_dir="$HOME/none" added in a3f2eec862b (ci/lib: allow running in GitHub Actions, 2020-04-08) for the GitHub CI can be removed. It appears to have been added to appease the subsequent 'mkdir -p "$cache_dir"', which wasn't needed in GitHub CI. 1. https://lore.kernel.org/git/patch-1.1-eec0a8c3164-20211217T000418Z-avarab@xxxxxxxxx/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> --- ci/lib.sh | 91 --------------------------------------- ci/run-build-and-tests.sh | 2 - ci/run-static-analysis.sh | 2 - ci/test-documentation.sh | 2 - 4 files changed, 97 deletions(-) diff --git a/ci/lib.sh b/ci/lib.sh index 510b20726ab..d12eaf338f9 100755 --- a/ci/lib.sh +++ b/ci/lib.sh @@ -13,75 +13,6 @@ then exit 1 fi -skip_branch_tip_with_tag () { - # Sometimes, a branch is pushed at the same time the tag that points - # at the same commit as the tip of the branch is pushed, and building - # both at the same time is a waste. - # - # When the build is triggered by a push to a tag, $CI_BRANCH will - # have that tagname, e.g. v2.14.0.
