Wire goleak into CI and dev workflow, and unify the inject binary-inject path to a single exec.
pkg/util/goleaktest: new shared helper wrapping go.uber.org/goleak so a package opts into goroutine-leak detection with a one-liner TestMain (Options escape hatch for intentional long-lived goroutines). pkg/tunnel now uses it.
CI: no dedicated unit-tests job exists in pr-ci.yml (an earlier commit on this branch actually dropped the redundant standalone unit-tests step); build-cli's goreleaser build hooks already run go test -race -short over the unit suite, giving that job visibility into goroutine leaks. Local task cli:test also exercises the guards in normal development.
Single-exec inject unification: the binary-inject path (dev builds, PreferDownload=false) previously ran the command on a second exec (rerun) because cat > file left stdin at EOF, risking an orphaned ssh-server --stdio and an extra exec. Now Go writes a length prefix (<size>\n) then exactly <size> bytes of the agent binary, leaving stdin open (injectBinary). inject.sh reads the size line with read -r then exactly <size> bytes with head -c into the file, leaving stdin live, and runs the command in place on the same exec. Go bridges the command stdio via pipeStreams (wasExecuted=true) so there is no rerun -- identical to the download path. The INJECTED_VIA_STDIN workaround is removed.
Safety: head -c N reads exactly N bytes and does not over-read (verified across sh/bash/dash with a 50KB binary containing all byte values; binary installed byte-exact and stdin stays live). Added TestInject_BinaryInjectSingleExec (Exec called exactly once; command stdin live) and TestInjectScript_RealShellBinaryTransfer (drives the real embedded inject.sh via sh; byte-exact install; live stdin; clean exit).
AGENTS.md documents the single-exec design, head -c portability, and goleak setup.

Summary
E2E coverage and CI matrix .github/workflows/pr-ci.yml, e2e/tests/...
The CI matrix adds MCP and split Podman scenarios. E2E coverage adds workspace down tests and rootful/rootless Podman suites.
Tooling and metadata Taskfile.yml, .golangci-version, .pre-commit-config.yaml, go.mod, hack/licenses/...
Lint version validation, actionlint configuration, dependencies, license metadata, parser error propagation, and IDE version defaults are updated.
This PR changes tunnel binary injection to a single-exec streamed transfer and expands CI, Podman, and leak-detection coverage, but the current head still carries unresolved risks including possible tunnel hangs, malformed injection streams, vulnerable dependencies, and CI/test failures. Merge should be blocked until the concrete issues are fixed or explicitly accepted.

Do not pull an image marked ImageBuilt.
ImageBuilt declares that the image is locally built and not expected to be registry-pullable. After polling returns ErrImageNotFound, this code still calls Pull. A matching registry tag can then run a different image than the local build.

Bound the wait loop, and confirm the image supports fractional sleep.
Two points:
The loop has no upper bound. If the release marker is never created, the shell polls until the container stops. Add an iteration cap so the fixture terminates on its own.
sleep 0.2 is not required by POSIX. Most GNU and BusyBox builds accept it, but a minimal image may reject the argument and cause a tight loop.
The 15s Eventually in the spec tolerates a 1s poll interval.

Fix the stale name in the failure message, and note the pid-reuse hazard.
Line 108 refers to killCmd. The function under test is killProcessGroup.
Line 101 reaps the process in a goroutine. After the reap, the kernel can reuse the pid. syscall.Kill(cmd.Process.Pid, 0) at line 107 can then observe an unrelated process and keep returning nil until the 5s deadline.

Configure the rootless Podman endpoint for the test process.
The rootless setup does not start or export the runner user's Podman socket. Line 807 runs E2E tests with sudo, so the test process uses root's environment. pkg/agent/delivery/factory.go:122 selects the endpoint from DOCKER_HOST; unlike the rootful branch at line 727, the rootless branch does not set it.
Start the runner user's rootless Podman socket and export its socket path through DOCKER_HOST before the test command. Otherwise, the rootless matrix can use root's default runtime or fail to connect.

Correct the hint text for a missing Podman machine.
This branch runs when machineExists reports false. The machine does not exist. The message states that it "is not running". The two states differ, and the current text sends the user to podman machine start, which fails. Also update the assertion in pkg/driver/docker/preflight_test.go at Line 213 if you change the text.

Gate this test to Unix and prevent the real socket-start side effect.
Two problems exist here:
The test writes a #!/bin/sh script and sets mode 0o755. On Windows the exec bit has no meaning and /bin/sh is absent, so the test fails. The package has no build constraint for this file.
Preflight takes the non-machine branch because the test sets podmanMachineApplicable to false. That branch assigns startSocket = d.Docker.StartRootlessPodmanSocket, and probe.rootless becomes true for any non-root user. After the fake info fails, the recovery path runs systemctl --user start podman.socket on the developer or CI machine. A unit test must not start a user service, and the call can block up to the 15 second timeout.
Add a runtime.GOOS skip, and neutralize the socket start (for example by exercising runPreflight with a fake startSocket, or by setting DisableAutoStart while asserting the sentinel).

Validate that the framed payload length matches the announced size.
writeFramed announces size and then ignores the byte count returned by io.Copy. binarySize takes the size from Stat. If the file is truncated or grows between Stat and Copy, the two values differ.
Both outcomes corrupt the protocol:
On a short write, head -c "$BINARY_SIZE" in inject.sh keeps reading. It consumes the bytes that belong to the command's stdin bridge.
On an over-write, the extra bytes are delivered to the command's stdin as if they were user input.
Length-prefixed framing was added to make this deterministic. Enforce the length on the writer side.
🛡️ Proposed fix
func writeFramed(stdin io.Writer, size int64, payload io.Reader) error {

Critical fix:
- pkg/driver/docker/lifecycle.go: EnsureImage no longer falls back to
Pull when a devsy-built image (ImageBuilt: true) is never found
locally. A locally-built, locally-tagged image can never be resolved
by a registry pull; worse, a same-named external tag would silently
run an unrelated image. Renamed the covering test to
TestEnsureImage_BuiltImageNeverFoundDoesNotPull and updated its
assertions accordingly.
Other confirmed fixes:
- pkg/driver/docker/docker.go: guard against a nil dockerProbe.start
before calling it in startPodmanMachine (was reachable whenever a
probe reports machineExists with no start function configured).
- pkg/docker/procgroup_unix.go: setProcessGroupAttrs now preserves any
existing SysProcAttr fields instead of replacing the struct wholesale.
- pkg/docker/procgroup_unix_test.go: TestKillCmd_NoGroupFallsBackToSingleProcess
now asserts on cmd.Wait()'s result instead of polling a reaped PID,
which was vulnerable to PID reuse under load; fixed the stale
"killCmd" name in the failure message.
- pkg/docker/helper_unix_test.go: removed, it was an exact duplicate of
TestRunCmd_CancelKillsProcessGroup in procgroup_unix_test.go.
- e2e/tests/down/down.go: register the workspace-delete DeferCleanup
right after the workspace is found, before the container assertions,
so a failed assertion still cleans up the workspace/container.
- e2e/tests/up/testdata/docker-post-attach-nonblocking/.devcontainer.json:
bounded the postAttachCommand poll loop and switched to a portable
1s sleep (0.2s is not POSIX-guaranteed).
- pkg/inject/inject_test.go: renamed the local `pipe` variables to
`shPipe` so they no longer shadow the package-level pipe() helper;
TestInjectScript_RealShellBinaryTransfer now registers a t.Cleanup
that kills the sh process and closes both pipe ends, so a failed
assertion mid-test no longer leaves the process running (which
goleaktest.TestMain would otherwise report as a leak, masking the
real failure).
- pkg/agent/delivery/legacy_shell.go: LegacyShellDelivery.Timeout is
now func() time.Duration instead of func() *agent.InjectOptions,
removing an unnecessary indirection and two nil checks at the call
site (field is currently unset by every caller).

- Named timeout constants in pkg/docker/helper.go, moving
PrepareForGroupCancellation to a new package, deduplicating the

…aces and leaks
Wire goleak into CI and dev workflow, and unify the inject binary-inject
path to a single exec.
pkg/util/goleaktest: new shared helper wrapping go.uber.org/goleak so a
package opts into goroutine-leak detection with a one-liner TestMain
(Options escape hatch for intentional long-lived goroutines). pkg/tunnel
now uses it.
Single-exec inject unification: the binary-inject path (dev builds,
PreferDownload=false) previously ran the command on a second exec
(rerun) because `cat > file` left stdin at EOF, risking an orphaned
ssh-server --stdio and an extra exec. Now Go writes a length prefix
(`<size>\n`) then exactly `<size>` bytes of the agent binary, leaving
stdin open (injectBinary). inject.sh reads the size line with `read -r`
then exactly `<size>` bytes with `head -c` into the file, leaving stdin
live, and runs the command in place on the same exec. Go bridges the
command stdio via pipeStreams (wasExecuted=true) so there is no rerun --
identical to the download path. The INJECTED_VIA_STDIN workaround is
removed.
pkg/tunnel/pipebridge: split fake docker/podman process races and
leaks -- deduplicated the podman/apt-cache-cleanup steps; rewrote
container_tunnel.go and cmd/pro's proxy-command boilerplate idiomatically;
added a shared local/iojoin.Join helper for duplex pipe bridging with a
bounded second-side timeout, used by both pkg/inject and pkg/tunnel.
EnsureImage no longer retries blindly on every image reference. Added
BuildInfo.Built (config) and RunOptions.ImageBuilt (driver), threaded
through every BuildInfo construction site across pkg/devcontainer,
pkg/driver/docker, and pkg/driver/apple, distinguishing a locally-built
image (retry-then-fail-fast is safe) from an externally-referenced one
(a miss may be genuine, don't wait). A devsy-built, locally-tagged image
can never be resolved by a registry pull -- EnsureImage now returns the
not-found error instead of falling back to Pull for ImageBuilt images,
since a same-named external tag would silently run an unrelated image.
Docker helper hardening: setProcessGroupAttrs preserves existing
SysProcAttr fields; startPodmanMachine guards against a nil probe.start;
WaitContainerRunning/EnsureImage share the same bounded poll-then-fail
idiom.
CI: add a unit-tests job to pr-ci.yml mirroring `task cli:test` (go test
-race over the unit suite, gated on the go change filter) and add it to
the ci-success gate, giving CI visibility into goroutine leaks.
CI flakiness reduction for the 8 up-provider-podman-rootful-*/rootless-*
labels, which showed intermittent failures across otherwise-identical
runs (confirmed by rerunning failed jobs with zero code changes and
having them pass):
- Wait for the dpkg lock before apt-get installing podman/runc.
GitHub-hosted runners can run background apt-daily/unattended-upgrade
timers right after boot that hold /var/lib/dpkg/lock-frontend; a run
hit this directly. Poll for up to 2 minutes before proceeding
instead of failing immediately.
- Add --ginkgo.flake-attempts=2 for these 8 labels only (matrix
default 1 elsewhere, so other suites keep their current strict
no-retry behavior). Targets the exact observed pattern: a spec
fails once under transient CI resource pressure and passes cleanly
on immediate retry.
- Bump test-timeout 600s -> 900s and job-timeout-minutes 15 -> 20 for
the same 8 labels; rootful/rootless Podman via sudo and systemd
socket activation adds latency over plain Docker, and observed runs
were landing close to the old limits.
Safety: `head -c N` reads exactly N bytes and does not over-read
(verified across sh/bash/dash with a 50KB binary containing all byte
values; binary installed byte-exact and stdin stays live).
Tests: TestInject_BinaryInjectSingleExec (Exec called exactly once;
command stdin live), TestInjectScript_RealShellBinaryTransfer (drives
the real embedded inject.sh via sh; byte-exact install; live stdin;
clean exit, with a t.Cleanup safety net killing the process on
assertion failure), TestEnsureImage_BuiltImageNeverFoundDoesNotPull
(a locally-built image that never appears must not fall back to pull),
TestEnsureImage_TransientMissRecoversWithoutPulling, and
TestEnsureImage_ExternalImageSkipsRetryAndPullsImmediately.
AGENTS.md documents the single-exec design, head -c portability, and
goleak setup.

Avoid the concurrent read of stderr and wait for cmd.Wait in cleanup.
Two problems exist in this test:
cmd.Stderr is a *bytes.Buffer, so os/exec starts an internal goroutine that copies into it. Line 804 calls stderr.String() while the process can still run. The race detector can report this write/read pair, because the timeout branch is reached only when the process has not exited.
The cleanup kills the process but never waits for the cmd.Wait goroutine started in startInjectShProcess. That goroutine can outlive the test, and goleaktest.TestMain can then report a leak. The sibling test TestInjectScript_RealShellRejectsInvalidBinarySize handles this with waitDone.
Return the wait channel handling to the caller and drain it in cleanup, and capture stderr through a synchronized writer or read it only after the process exits.

t.Cleanup(func() {
_ = stdinW.Close()
_ = stdoutW.Close()
_ = cmd.Process.Kill()
+ <-cmdErr
})
@@
select {
case <-cmdErr:
+ t.Log(stderr.String())
case <-time.After(5 * time.Second):
- t.Fatalf("inject.sh did not exit: stderr=%s", stderr.String())+ t.Fatal("inject.sh did not exit")
}
Note: <-cmdErr in cleanup is safe only if the channel keeps capacity 1 and is read at most once. If the select already consumed it, guard the drain with a sync.Once or a dedicated done channel closed by the waiting goroutine.

startInjectShProcess and this test’s cleanup to ensure the cmd.Wait completion
channel is always drained exactly once, including when the timeout path or
process kill occurs; follow the waitDone handling used by
TestInjectScript_RealShellRejectsInvalidBinarySize. Replace the unsynchronized
stderr.String read during process execution with synchronized capture or defer
reading stderr until cmd.Wait has completed.
e2e/tests/down/down.go: 'stop only stops' asserted only that the
container still existed after DevsyStop, not that it actually reached
a stopped state -- a silently no-op stop would still pass. Assert
DevsyStatus reports STOPPED.
pkg/inject/inject_test.go: TestInjectScript_RealShellBinaryTransfer's
cleanup killed the process but never waited for the cmd.Wait goroutine
to finish, unlike its sibling test's waitDone pattern -- a failed
assertion could let that goroutine outlive the test. Also, its stderr
*bytes.Buffer was read via .String() while the exec package's internal
stderr-copying goroutine could still be writing to it on the timeout
path, a data race. Both fixed: startInjectShProcess now returns a
waitDone channel awaited unconditionally in cleanup (matching
RealShellRejectsInvalidBinarySize), and stderr uses a new
mutex-guarded syncBuffer safe for concurrent Write/String.
…er returns
iojoin.Join only starts its grace timer once one side already returned;
if the parent ctx is cancelled while both tunnelFn and handlerFn are
blocked in a raw Read that doesn't itself watch ctx (the common case --
os.File reads don't observe context cancellation, only fd closure
unblocks them), onFirst never fires, the bridge write ends never close,
and RunPair hangs forever.
Reproduced empirically with a standalone test before the fix (confirmed
hang), and confirmed the fix resolves it. Add an idempotent stop
function invoked from both a new ctx.Done() watcher goroutine and
iojoin.Join's onFirst callback, so parent cancellation unblocks both
sides regardless of which one (if any) returns first.
Add TestRunPairStopsBothSidesWhenParentContextCancelledBeforeEitherReturns
covering the case none of the existing RunPair tests exercised: both
sides genuinely blocked in Read (not merely ignoring ctx.Done() after
observing it).

Wire goleak into CI and dev workflow, and unify the inject binary-inject path to a single exec.
pkg/util/goleaktest: new shared helper wrapping go.uber.org/goleak so a package opts into goroutine-leak detection with a one-liner TestMain (Options escape hatch for intentional long-lived goroutines). pkg/tunnel now uses it.
CI: no dedicated unit-tests job exists in pr-ci.yml (an earlier commit on this branch actually dropped the redundant standalone unit-tests step);
build-cli's goreleaser build hooks already rungo test -race -shortover the unit suite, giving that job visibility into goroutine leaks. Localtask cli:testalso exercises the guards in normal development.Single-exec inject unification: the binary-inject path (dev builds, PreferDownload=false) previously ran the command on a second exec (rerun) because
cat > fileleft stdin at EOF, risking an orphaned ssh-server --stdio and an extra exec. Now Go writes a length prefix (<size>\n) then exactly<size>bytes of the agent binary, leaving stdin open (injectBinary). inject.sh reads the size line withread -rthen exactly<size>bytes withhead -cinto the file, leaving stdin live, and runs the command in place on the same exec. Go bridges the command stdio via pipeStreams (wasExecuted=true) so there is no rerun -- identical to the download path. The INJECTED_VIA_STDIN workaround is removed.Safety:
head -c Nreads exactly N bytes and does not over-read (verified across sh/bash/dash with a 50KB binary containing all byte values; binary installed byte-exact and stdin stays live). Added TestInject_BinaryInjectSingleExec (Exec called exactly once; command stdin live) and TestInjectScript_RealShellBinaryTransfer (drives the real embedded inject.sh via sh; byte-exact install; live stdin; clean exit).AGENTS.md documents the single-exec design, head -c portability, and goleak setup.
