bare-stow-host-python
Host side of the bare-stow lifecycle for Python. The Python counterpart of bare-stow-host: it multiplexes a control channel and a user data channel over a byte transport to a stowed bundle, and layers readiness, termination, and exit reporting on top. Harnesses generated by bare-stow import it to drive the bundles they boot.
pip install bare-stow-host
Usage
import signal
from bare_sidecar import spawn
from bare_stow_host import wrap
async def main():
sidecar = await spawn("index.bundle")
ipc = wrap(sidecar, kill=lambda: sidecar.kill(signal.SIGKILL))
await ipc.ready
await ipc.write(b"hello")
code = await ipc.terminate()
Any object with async read(), returning b"" once the transport has ended, and async write(data) can be wrapped, such as a Sidecar from bare-sidecar-python.
Protocol
Every frame is a 4-byte little-endian length followed by that many bytes: A 1-byte tag and the payload. The tag is 0x00 for a control frame, whose payload is a UTF-8 JSON object carrying its type, and 0x01 for a user data frame. See bare-stow-protocol for the control frames.
