Review direction (tianyicui, PR #660): make the interface closer to Node's API so the other process-running places can adopt it. The spec gains per-stream stdio dispositions — 'pipe' (raw Readable/Writable for protocol streams), 'inherit' (diagnostics to the parent), and collect mode ({maxBytes, spill?} — the old bounded tail-keep shape, now with spill optional for diagnostic tails). SubprocessOutcome carries exit facts only; collected output stays readable through handle.collected after settlement (spill fds are sealed at the settle boundary). The handle grows Node-style kill(signal) (single signal, tree-scoped, no-op after settlement), terminate() (the SIGTERM→grace→SIGKILL escalation, also driven by the spec signal), waitForExit() (tree liveness, not just the direct child), and dispose() (the cooperative stdin-EOF→SIGTERM→SIGKILL ladder from subagent-subprocess, graces caller-supplied). Tree semantics are platform-correct: POSIX detached groups with direct-child fallback; Windows taskkill /T with an injectable runner. scrubbedParentEnv/SENSITIVE_ENV_PATTERN move to the seam as the one shared scrub definition. bash-local maps its config onto collect modes and batch stdin and reads results through the collected readers; its kill() maps to terminate() so task_kill keeps escalation semantics.
subprocess/ — subprocess capability family
The shared home for spawning managed child-process groups: fully-specified spawn specs, bounded tail-keep output with spill files, credential-scrubbed environments, offset-based incremental reads, and SIGTERM→grace→SIGKILL group kills. Command defaulting, shell semantics, deadlines, and presentation stay with consumers — the bash executor family is the first and owning consumer. See the subprocess seam Agent Note.
| Package | ctx key | Role |
|---|---|---|
subprocess (@deepseek-ai/dsh-subprocess) |
ctx.subprocess |
The seam: abstract SubprocessService.spawn(spec), the fully-explicit SubprocessSpawnSpec, SubprocessHandle with offset-based readers, and the shared DSH_* managed-environment and CollectedOutput vocabulary |
subprocess-local (@deepseek-ai/dsh-subprocess-local) |
— | The local implementation: detached process groups, tail-keep truncation with bounded private spill files, the credential scrub and DSH_* merge order, kill escalation, and kill-and-join disposal |
The service owns process lifetime across consumer reloads; consumers own what a process means (a bash command, a future non-shell runner) and every default that shapes one.
