📝 Walkthrough

Walkthrough

The PR adds reusable rootless and rootful Podman setup, Podman recovery and volume-write handling, expanded Podman E2E coverage, bounded readiness checks, remote agent timeouts, and centralized GolangCI-Lint version validation.

Changes

Podman runtime support

Layer / File(s) Summary
Reusable Podman CI setup
.github/actions/install-podman-linux/action.yml, .github/workflows/pr-ci.yml
The composite action installs and configures rootless or rootful Podman, waits for socket readiness, exports DOCKER_HOST, and runs preflight checks. CI uses separate rootless and rootful configurations.
Volume write fallback
pkg/agent/delivery/local_docker.go, pkg/agent/delivery/local_docker_test.go
Volume population writes directly first and falls back to podman unshare after permission failures. Tests cover both paths.
Podman probing and socket helpers
pkg/docker/helper.go, pkg/docker/helper_test.go, pkg/docker/rootless.go, pkg/docker/linger.go
Helpers detect Podman machines, probe rootless mode, start the user socket, and update linger warnings.
Podman preflight recovery
pkg/driver/docker/docker.go, pkg/driver/docker/preflight_test.go, pkg/driver/docker/useruid_test.go
Preflight selects machine or rootless socket recovery, retries the backend, and preserves applicable errors and hints.
Rootless and rootful Podman E2E coverage
e2e/tests/up/provider_podman_rootless.go, e2e/tests/up/provider_podman_rootful.go, e2e/e2e_suite_test.go
Separate suites cover startup, builds, lifecycle commands, agent delivery, SSH, configuration, volumes, custom images, and cleanup.
Bounded daemon and agent checks
e2e/tests/machineprovider/testdata/*/provider.yaml, e2e/tests/tunnel/testdata/tunnel/provider.yaml, pkg/agent/inject.go, pkg/agent/inject_test.go
E2E providers poll nested Docker daemons with timeout diagnostics. Remote agent version checks use a bounded context.

Lint version validation

Layer / File(s) Summary
Pinned lint version
.golangci-version, .github/workflows/pr-ci.yml
The repository declares GolangCI-Lint version v2.12.2, and CI reads the version from that file.
Lint task verification
Taskfile.yml
Lint, fix, and format tasks validate the installed version. CI linting also verifies the GolangCI-Lint configuration.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 1ab44

The PR adds rootful Podman setup that can let blocked commands stall CI until the suite timeout and provide little diagnostic context. This is a concrete merge-readiness issue that should receive owner follow-up before merge.

The fallback must create an executable agent binary. This test verifies content only, so it passes if the fallback removes chmod 755.

Fail the test if the direct-write path invokes unshare.

The fixture executes unshare successfully. The test therefore passes if populateVolumeDirectCopy incorrectly uses the fallback. Make the unshare branch return an error in this test.

In @.github/actions/install-podman-linux/action.yml:
- Around line 58-70: Update the readiness check and both Podman probes in the
action to use the remote client with the explicit unix endpoint PODMAN_SOCK by
adding the equivalent of --remote --url "unix://$PODMAN_SOCK" to each
invocation. Run the final busybox smoke test through sudo while preserving the
same remote endpoint, so it validates the connection used by the E2E process.

In @.github/workflows/pr-ci.yml:
- Around line 60-63: Replace the direct golangci-lint action invocation in the
workflow with the repository’s task cli:lint:ci command, while retaining GitHub
Actions-specific cache configuration. Add a dedicated Taskfile task for Podman
installation and update the composite action to invoke that task instead of
installing Podman directly; use the existing Taskfile conventions and symbols
for both changes.

In `@pkg/docker/helper.go`:
- Around line 170-178: Update DockerHelper.PodmanMachineExists to preserve
machine-list errors separately from a confirmed empty result. In
pkg/docker/helper.go lines 170-178, change the result contract and callers
accordingly; in pkg/driver/docker/docker.go lines 161-198, make recoverPodman
choose user or system socket recovery only when rootless/rootful detection
succeeds, and propagate unknown-mode detection errors. In
pkg/driver/docker/preflight_test.go lines 107-193, add coverage for failed
machine detection and rootful recovery when no machine exists.

In `@pkg/docker/linger.go`:
- Around line 14-15: Restore a five-second timeout around the context passed to
probeRootlessPodman in LingerWarning, ensuring the rootless Podman probe cannot
block indefinitely when the incoming ctx has no deadline. Preserve the existing
rootless result handling and use the derived context for the probe.

- Around line 181-195: Update the two Info log messages in the machine-start and
rootless-socket paths to begin with lowercase “podman” instead of “Podman”;
leave the surrounding behavior unchanged.

In `@Taskfile.yml`:
- Around line 41-50: Add deps: [cli:lint:version] to the cli:lint:fix and

📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift

Route lint and Podman setup through Taskfile tasks.

The workflow runs lint through golangci-lint-action and installs Podman through a composite action. This splits repository setup and lint behavior between workflow YAML and Taskfile commands.

Move command-level lint behavior to task cli:lint:ci. Add a Taskfile command for Podman installation, then let the composite action call that command. Keep GitHub Actions-specific cache wiring in the workflow or action.

As per coding guidelines, use Taskfile commands for repository setup, builds, tests, formatting, and linting rather than invoking disparate tooling directly.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Avoid using machine absence as rootless detection. A rootful Podman installation can have no machine, so this path may start the user socket instead of recovering the system socket. Determine execution mode separately before selecting socket recovery, and add a rootful no-machine test.

Pull Request Overview

This PR significantly improves the reliability of Podman rootless environments by introducing dedicated setup actions, readiness checks, and preflight recovery logic. The implementation addresses common flakiness by verifying the Podman socket before execution and providing automated systemd socket management on Linux.

While the codebase is up to standards according to Codacy, there are two primary areas for improvement: environment-specific execution and error reporting. The use of systemctl --user commands may fail in CI environments if the user session bus is not correctly configured via environment variables. Additionally, the error hints for missing Podman sockets are currently Linux-centric and should be adapted for macOS and Windows users. Refactoring the test suite to use a factory pattern for probe initialization would also reduce duplication and improve maintainability.

About this PR

  • This PR introduces significant production logic for automated systemd socket management and build-time chores that extend beyond the 'fixing flakiness' scope described in the title. While these changes improve environment reliability, ensure they align with the intended architectural scope.

Test suggestions

  • Verify detection of existing Podman machines via 'machine list' parsing
  • Verify Preflight recovery logic triggers a Podman machine start when machine exists
  • Verify Preflight recovery logic triggers a systemd user socket start for rootless Linux environments
  • Verify volume population fallback to 'unshare' specifically when a direct host write fails with os.ErrPermission
  • Verify the Podman rootless detection probe correctly identifies mode via 'info' format templates

🟡 MEDIUM RISK

Suggestion: The error hint for a missing Podman socket specifically suggests systemctl commands, which are Linux-only. For users on macOS or Windows, a hint suggesting podman machine init or podman machine start would be more accurate.

⚪ LOW RISK

Nitpick: The repetitive initialization of the dockerProbe struct across various test cases (e.g., lines 110, 132, 155) introduces significant duplication. Abstracting this setup into a factory function or a default probe builder would make the tests more maintainable.

Bound all readiness probes and diagnostics.

All six blocks use the same unbounded loop. A blocked docker exec ... docker info prevents i from advancing, so the loop can hang indefinitely. Bound the entire readiness loop and docker logs --tail 50 ... with wall-clock timeouts. Run the affected suites with task cli:test:e2e:suite.

Write the wrapper script with a single os.WriteFile call.

os.WriteFile sets the mode at creation time. This removes the os.Create, WriteString, Close, and os.Chmod sequence, along with the manual close-on-error path.

Consider adding the non-root remoteUser spec to the rootful suite.

e2e/tests/up/provider_podman_rootless.go lines 50-73 cover remoteUser and workspace-folder ownership. The rootful suite omits it. UID mapping and chown behavior differ most between rootless and rootful Podman, so this is the case where rootful coverage adds the most value.

Do you want me to draft the equivalent spec for this file?

Duplicated Podman spec bodies in e2e/tests/up/provider_podman_rootless.go and e2e/tests/up/provider_podman_rootful.go. Both suites register the same specs and differ only in the provider setup step. The shared root cause is copy-based spec registration instead of one parameterized registration helper. Each future spec change must then be applied twice, and the suites can drift.

  • e2e/tests/up/provider_podman_rootless.go#L37-L679: move these spec registrations into a shared function that receives a *framework.Framework accessor, and call it from this Describe.
  • e2e/tests/up/provider_podman_rootful.go#L60-L677: call the same shared registration function after the rootful wrapper setup instead of repeating the spec bodies.

Bind the rootful probe to the spec context and report its output.

exec.Command(...).Run() ignores ctx. If sudo waits for a password, this BeforeEach blocks until the suite-level timeout instead of failing at the spec deadline. Run() also discards stdout and stderr, so a failure reports only exit status N with no cause.

Use exec.CommandContext and include the combined output in the failure.

♻️ Proposed fix
-			err = exec.Command(initialDir+"/bin/podman-rootful", "ps").Run()
-			framework.ExpectNoError(err)
+			out, err := exec.CommandContext(
+				ctx, initialDir+"/bin/podman-rootful", "ps",
+			).CombinedOutput()
+			framework.ExpectNoError(err, "rootful podman probe failed: %s", string(out))

Note: the ast-grep command-injection hint on this line is a false positive. initialDir comes from os.Getwd, the arguments are fixed, and no shell is invoked.

- helper.go: bound isSystemdRunning by the caller's context so the
  15s StartRootlessPodmanSocket timeout actually applies to the
  systemd probe, not just the socket start.
- linger.go: only warn about missing linger when the rootless probe
  succeeds and confirms rootless (ok && rootless), not on probe
  failure (!ok || rootless previously misfired on any probe error).
- docker.go: lowercase "podman" in log messages per repo convention.
- install-podman-linux action: derive XDG_RUNTIME_DIR from the UID
  instead of trusting an inherited env var that composite action
  shells may not have.
- provider_podman_rootful.go: write the wrapper script with a single
  os.WriteFile call; run the rootful probe via exec.CommandContext
  and surface combined output on failure.
- local_docker_test.go: assert executable permissions after the
  unshare fallback; make the direct-write test's unshare branch fail
  so it can't mask an incorrect fallback.
- gofmt/goimports cleanup on e2e_suite_test.go and
  provider_podman_rootless.go.
- add linger_test.go coverage for the fixed LingerWarning branching
  (probe failure, rootful, rootless-without-linger, non-podman).

runCmd's cmd.Cancel killed only cmd.Process, the direct child. A
privilege-elevation helper (sudo, pkexec, doas, or the ad-hoc "sudo
podman" wrapper the rootful e2e suite uses) forwards catchable signals
to the command it launches, but SIGKILL cannot be caught or forwarded:
killing the helper's PID leaves its child (the actual podman process)
running and orphaned. That child keeps holding the pipes runCmd's
cmd.Run() is waiting on open, so Run() blocks until the orphan happens
to exit on its own.

This is exactly the observed CI failure: "Test up-provider-podman-rootful"
timed out after a 3-minute spec timeout and then hung for the full 25m
test binary timeout, both times stuck in os.(*Process).Wait() right
after agent injection completed. The rootless job (no sudo wrapper) is
unaffected and passes.

Fix: put every docker/podman invocation in its own process group
(Setpgid) and kill the negative PID (the whole group) instead of just
the leader on cancellation. Windows has no process-group signal
equivalent, so it keeps killing the single process.

Added TestRunCmd_CancelKillsProcessGroup, which spawns a background
grandchild standing in for the elevated child process and asserts
cancellation reaps it too; verified it fails (30s) against the old
leader-only kill and passes (<1s) with the fix.

Signed-off-by: Samuel K <skevetter@pm.me>
The previous commit always puts docker/podman invocations in their
own process group so cancellation can kill an elevation helper's
orphaned child. That's wrong for the interactive case (`devsy exec`,
`devsy config apply`, ... — anywhere Streams.Stdin is os.Stdin):
the terminal delivers Ctrl+C to its foreground process group, and
devsy relies on the child sharing devsy's own group for that Ctrl+C
to reach it directly. Isolating it would silently break interactive
interrupt handling.

runCmd now only isolates the group when Stdin isn't the live
terminal. killCmd mirrors this: it only signals the negative PID when
cmd was actually given its own group (cmd.SysProcAttr.Setpgid), since
otherwise that "group" is devsy's own and signaling it would kill
devsy too.

Added TestRunCmd_InteractiveStdinKeepsSharedProcessGroup and
TestKillCmd_NoGroupFallsBackToSingleProcess to lock in both halves of
this tradeoff.
