fix: docker.sock reliability + release 1.0.7 - #76
Conversation
Close both proxy sides when either direction ends so vsock half-closes cannot leak FDs, and share a modest engine-connection gate between the public socket proxy and guest docker/nerdctl calls. Co-authored-by: Cursor <[email protected]>
Nil Go slices were serialized as null on list endpoints; WriteJSON now normalizes them to [] so the UI always receives an array. Co-authored-by: Cursor <[email protected]>
Retry force-remove after guest root scripts, label helpers for prune, drop them from container lists, and sweep stale ones when the engine starts so interrupted setup cannot leave ghost containers behind. Co-authored-by: Cursor <[email protected]>
Prefer docker compose, fall back to docker-compose, and run compose steps outside a subshell so failures count toward the summary. Co-authored-by: Cursor <[email protected]>
Keep hijacked attach streams open after the CLI half-closes, and force Connection: close on plain API calls so keep-alive cannot wedge vsock. Co-authored-by: Cursor <[email protected]>
📝 WalkthroughWalkthroughThe PR improves Docker socket proxying, limits macOS guest connections, cleans up helper containers, normalizes empty API lists, filters guest commands, and adds Compose CLI fallback support. ChangesDocker reliability
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The runtime can report Docker ready while a restart is still pending, causing connection failures, and cleanup may remove another container’s metadata when IDs share a prefix. Additional open proxy and verification issues can cause hangs, truncated responses, starvation, or false-positive checks. Merge should be blocked until the runtime cleanup/readiness and proxy correctness issues are fixed. Sequence Diagram(s)sequenceDiagram

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Bound the connection-slot wait with an explicit timeout.
acquireConn(parent) blocks on the shared gate. parent is p.lifecycle or context.Background(), so neither carries a deadline. If the guest holds all 8 slots (for example during a long docker logs -f or AttachExec), each new client connection parks a goroutine until the daemon shuts down, and the CLI sees a hang instead of an error.
Create the bounded context first, then acquire with it. This also matches the guideline to thread an explicit timeout into blocking runtime calls.

Wait for the plain HTTP response before closing the proxy.
When the client half-closes, the client-to-server copy can finish first. The current code then closes both connections and truncates dockerd’s response. Track each copy direction separately, wait for server-to-client completion, and use a bounded grace period. Add a TCP test that calls CloseWrite on the plain path and checks the complete response body.

Log the cleanup failure and trim id before the comparison.
The retry loop discards every docker rm -f error. After three attempts the function returns without any record, so a leftover calf-guestcmd-* container is invisible in the logs. The guideline requires that a reader can tell which operation failed.
name != id at Line 278 compares the trimmed name against the untrimmed id. If id carries whitespace, the function appends a duplicate target. The extra docker rm -f is harmless but wasteful.

dockerAPIReady now reports "not ready" when the local gate is saturated.
The function returns false if AcquireEngineConn does not get a slot inside 400 ms. That result describes host-side contention, not engine state. Krunkit.Start treats a false result as a dead stack and runs stopKrunkitStack() (see backend/internal/runtime/krunkit_darwin.go lines 179 and 211). Eight concurrent slot holders — for example several docker logs -f streams plus proxied CLI traffic — can therefore cause a restart of a healthy VM and drop live connections.
Distinguish the two outcomes. One option is to bypass the gate for the _ping probe, because it is a single short request. Another option is to return the acquisition error separately so callers do not read it as "engine down".

Long-lived sessions and short requests share the same 8-slot gate. engineConnGate holds 8 slots. streamLogsFollow and AttachExec each keep one slot for the whole session lifetime, while runLocal and the public docker.sock proxy need slots for short requests. Eight open log-follow or exec sessions therefore block every UI action and every proxied CLI command. Give long-lived sessions a separate budget, or reserve a minimum number of slots for short requests.

Docker CLI docker psdefault container ID truncation and--no-trunc full ID behavior
💡 Result:
The Docker CLI command docker ps truncates container IDs by default to a 12-character hexadecimal prefix [1]. This truncation is applied to improve readability and provide a concise overview of container status [1]. To display the full 64-character container ID, you can use the --no-trunc flag with the command [1][2]: docker ps --no-trunc Key details regarding this behavior include: Default Truncation: Without the --no-trunc flag, the container ID column is limited to a short prefix [1]. While this is usually sufficient for human-readable output and basic identification, these short IDs may be ambiguous in environments with many containers [1]. Full ID Output: The --no-trunc flag ensures that the entire 64-character unique identifier is displayed [1]. This is particularly useful for automation, scripting, or when unique identification is required across a large set of containers [1]. Scripting and Automation: To extract only the full container IDs for use in other scripts or commands, you can combine --no-trunc with other flags such as -q (quiet) or use the --format option [1][3]: # To list only full IDs docker ps -q --no-trunc # To format specific output (e.g., just the ID) docker ps --no-trunc --format "{{.ID}}" The --no-trunc flag also affects other columns in the output, such as preventing truncation of the COMMAND or other details that might otherwise be cut off to fit the terminal width [4][1][2].

Wait for the scheduled restart before reporting Docker readiness.
CorruptContainerWipeScript schedules its restart one second later. The first docker info call can succeed before that restart begins. Krunkit.Start then continues and marks the runtime ready while the scheduled restart can still drop Docker connections.
Make the cleanup report completion only after the restart has run. Then poll Docker readiness after that completion signal.
