subprocess/ — subprocess capability family
English | 中文
The shared process substrate for one execution world: executable lookup, fully-specified managed child-process trees with raw or collected stdio, and one deep terminal-process primitive that owns PTY allocation, foreground groups, and provider-observable session cleanup. Command defaulting, shell semantics, deadlines, protocol framing, readiness, and presentation stay with consumers — the bash executors, LSP host, PTY shell backend, and ACP subagent backend. See the subprocess seam Agent Note.
| Package | ctx key | Role |
|---|---|---|
subprocess (@deepseek-ai/dsh-subprocess) |
ctx.subprocess |
Service Definition: executable lookup, ordinary managed spawns, the terminal-process primitive, handle lifecycles, and shared environment/output vocabulary |
subprocess-local (@deepseek-ai/dsh-subprocess-local) |
— | Local Service Provider: native managed ranges with disclosed fallbacks, bounded collection/spill, node-pty, foreground/session inspection, signalling, and terminate-and-join disposal |
win32-process (@deepseek-ai/dsh-win32-process) |
— | Windows-only low-level library: the single Koffi owner for sandbox and ordinary process creation, inherited/anonymous/named-pipe stdio, suspended Job assignment, polling, waits, and handle cleanup |
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.
The subsystem reference — spawn specs, output readers, outcomes, the DSH_* environment — is docs/subsystems/subprocess.md; the seam decision in the subprocess seam Agent Note.
