From ec05ab1e3c99270c46e93fc3113d6b2102a14c57 Mon Sep 17 00:00:00 2001 From: Zettat123 Date: Mon, 27 May 2024 14:15:34 +0800 Subject: [PATCH] Improve the handling of `jobs..if` (#31070) Fix #25897 Fix #30322 #29464 cannot handle some complex `if` conditions correctly because it only checks `always()` literally. In fact, it's not easy to evaluate the `if` condition on the Gitea side because evaluating it requires a series of contexts. But act_runner is able to evaluate the `if` condition before running the job (for more information, see [`gitea/act`](https://gitea.com/gitea/act/src/commit/517d11c67126bd97c88e2faabda0832fff482258/pkg/runner/run_context.go#L739-L753)) . So we can use act_runner to check the `if` condition. In this PR, how to handle a blocked job depends on its `needs` and `if`: - If not all jobs in `needs` completed successfully and the job's `if` is empty, set the job status to `StatusSkipped` - In other cases, the job status will be set to `StatusWaiting`, and then act_runner will check the `if` condition and run the job if the condition is met (cherry picked from commit 31a0c4dfb4156a7b4d856cceae1e61c7fc1a4a1b) --- services/actions/job_emitter.go | 14 +++++++------- services/actions/job_emitter_test.go | 18 +++++++++--------- 2 files changed, 16 insertions(+), 16 deletions(-) diff --git a/services/actions/job_emitter.go b/services/actions/job_emitter.go index d2bbbd9a7c..1f859fcf70 100644 --- a/services/actions/job_emitter.go +++ b/services/actions/job_emitter.go @@ -7,7 +7,6 @@ import ( "context" "errors" "fmt" - "strings" actions_model "code.gitea.io/gitea/models/actions" "code.gitea.io/gitea/models/db" @@ -141,18 +140,19 @@ func (r *jobStatusResolver) resolve() map[int64]actions_model.Status { if allSucceed { ret[id] = actions_model.StatusWaiting } else { - // If a job's "if" condition is "always()", the job should always run even if some of its dependencies did not succeed. - // See https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idneeds - always := false + // Check if the job has an "if" condition + hasIf := false if wfJobs, _ := jobparser.Parse(r.jobMap[id].WorkflowPayload); len(wfJobs) == 1 { _, wfJob := wfJobs[0].Job() - expr := strings.TrimSpace(strings.TrimSuffix(strings.TrimPrefix(wfJob.If.Value, "${{"), "}}")) - always = expr == "always()" + hasIf = len(wfJob.If.Value) > 0 } - if always { + if hasIf { + // act_runner will check the "if" condition ret[id] = actions_model.StatusWaiting } else { + // If the "if" condition is empty and not all dependent jobs completed successfully, + // the job should be skipped. ret[id] = actions_model.StatusSkipped } } diff --git a/services/actions/job_emitter_test.go b/services/actions/job_emitter_test.go index 038df7d4f8..58c2dc3b24 100644 --- a/services/actions/job_emitter_test.go +++ b/services/actions/job_emitter_test.go @@ -71,9 +71,9 @@ func Test_jobStatusResolver_Resolve(t *testing.T) { want: map[int64]actions_model.Status{}, }, { - name: "with ${{ always() }} condition", + name: "`if` is not empty and all jobs in `needs` completed successfully", jobs: actions_model.ActionJobList{ - {ID: 1, JobID: "job1", Status: actions_model.StatusFailure, Needs: []string{}}, + {ID: 1, JobID: "job1", Status: actions_model.StatusSuccess, Needs: []string{}}, {ID: 2, JobID: "job2", Status: actions_model.StatusBlocked, Needs: []string{"job1"}, WorkflowPayload: []byte( ` name: test @@ -82,15 +82,15 @@ jobs: job2: runs-on: ubuntu-latest needs: job1 - if: ${{ always() }} + if: ${{ always() && needs.job1.result == 'success' }} steps: - - run: echo "always run" + - run: echo "will be checked by act_runner" `)}, }, want: map[int64]actions_model.Status{2: actions_model.StatusWaiting}, }, { - name: "with always() condition", + name: "`if` is not empty and not all jobs in `needs` completed successfully", jobs: actions_model.ActionJobList{ {ID: 1, JobID: "job1", Status: actions_model.StatusFailure, Needs: []string{}}, {ID: 2, JobID: "job2", Status: actions_model.StatusBlocked, Needs: []string{"job1"}, WorkflowPayload: []byte( @@ -101,15 +101,15 @@ jobs: job2: runs-on: ubuntu-latest needs: job1 - if: always() + if: ${{ always() && needs.job1.result == 'failure' }} steps: - - run: echo "always run" + - run: echo "will be checked by act_runner" `)}, }, want: map[int64]actions_model.Status{2: actions_model.StatusWaiting}, }, { - name: "without always() condition", + name: "`if` is empty and not all jobs in `needs` completed successfully", jobs: actions_model.ActionJobList{ {ID: 1, JobID: "job1", Status: actions_model.StatusFailure, Needs: []string{}}, {ID: 2, JobID: "job2", Status: actions_model.StatusBlocked, Needs: []string{"job1"}, WorkflowPayload: []byte( @@ -121,7 +121,7 @@ jobs: runs-on: ubuntu-latest needs: job1 steps: - - run: echo "not always run" + - run: echo "should be skipped" `)}, }, want: map[int64]actions_model.Status{2: actions_model.StatusSkipped},
