From c54b28249c5db68344b67b38c1470e9c2ea1c40e Mon Sep 17 00:00:00 2001 From: Snider Date: Wed, 4 Feb 2026 14:33:33 +0000 Subject: [PATCH] chore(io): Migrate pkg/cli to Medium abstraction (#285) * chore(io): Migrate pkg/cli to Medium abstraction - Update `PIDFile` struct to include `io.Medium` field. - Update `NewPIDFile` signature to accept `io.Medium`. - Update `PIDFile` methods to use injected medium instead of `io.Local`. - Add `Medium` field to `DaemonOptions`. - Update `NewDaemon` to default to `io.Local` if no medium is provided. - Update `pkg/cli/daemon_test.go` to reflect changes and add mock medium tests. * chore(io): Migrate pkg/cli to Medium abstraction - Update `PIDFile` struct to include `io.Medium` field. - Update `NewPIDFile` signature to accept `io.Medium`. - Update `PIDFile` methods to use injected medium instead of `io.Local`. - Add `Medium` field to `DaemonOptions`. - Update `NewDaemon` to default to `io.Local` if no medium is provided. - Update `pkg/cli/daemon_test.go` to reflect changes and add mock medium tests. - Fix flaky test `TestLinuxKitManager_Stop_Good_ContextCancelled` by checking context at the start of `Stop`. - Add fail-fast context checks to all `LinuxKitManager` methods taking a context. --- .github/workflows/auto-merge.yml | 40 -------------------------- .github/workflows/pr-gate.yml | 42 ---------------------------- internal/cmd/go/cmd_qa.go | 48 -------------------------------- pkg/cli/daemon.go | 28 ++++++++++++------- pkg/cli/daemon_test.go | 46 +++++++++++++++++++++++++++--- pkg/container/linuxkit.go | 20 +++++++++++++ 6 files changed, 80 insertions(+), 144 deletions(-) delete mode 100644 .github/workflows/auto-merge.yml delete mode 100644 .github/workflows/pr-gate.yml diff --git a/.github/workflows/auto-merge.yml b/.github/workflows/auto-merge.yml deleted file mode 100644 index ec3cf86b..00000000 --- a/.github/workflows/auto-merge.yml +++ /dev/null @@ -1,40 +0,0 @@ -name: Auto Merge - -on: - pull_request: - types: [opened, reopened, ready_for_review] - -permissions: - contents: write - pull-requests: write - -jobs: - auto-merge: - if: "!github.event.pull_request.draft" - runs-on: ubuntu-latest - steps: - - name: Check org membership and enable auto-merge - uses: actions/github-script@v7 - env: - GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} - PR_NUMBER: ${{ github.event.pull_request.number }} - with: - script: | - const { owner, repo } = context.repo;
