Shared fixtures build DockerBottlePlan and SmolmachinesBottlePlan from
identical git_gate_plan and egress_plan inputs and assert that both
backends render the same git gate lines (name → host:port) and egress
lines (host [auth:scheme] when authenticated, host alone otherwise).
Move git_gate_plan, egress_plan, supervise_plan, and agent_provision
from DockerBottlePlan and SmolmachinesBottlePlan into BottlePlan.
Replace the abstract print method with a single concrete implementation
that renders git gate entries as "name → upstream_host:upstream_port"
and egress routes with conditional "[auth:scheme]" annotations.
Both remote-addr and peer-addr args to the access hook are the same
TCP peer in this non-proxied stack. Extract a `peer` variable so the
intentional repetition is visible. Closes#148.
Closes#140. In restart_daemon, the old process's stdout pipe was never
explicitly closed after p.wait() returned, leaking the fd until the
supervisor object was GC'd. Similarly, when the watch loop converged
(all children dead), no pipe was closed. Both paths now call
p.stdout.close() immediately after the process is confirmed exited.
Tests enforce this with warnings.simplefilter("error", ResourceWarning)
in TestSupervisor.setUp.
Closes#139. Adds tests/unit/test_backend_parity.py which verifies that
DockerBottle and SmolmachinesBottle expose identical observable contracts
for agent_argv shape, env injection, exec user-switching, ExecResult
fields, and close() idempotency. All assertions use mock subprocess
layers — no live Docker daemon or VM required.
Before this change, int() on a non-numeric Content-Length raised an
unhandled ValueError, crashing the request handler. There was also no
upper bound on how much memory a POST body could consume.
After this change:
- Non-numeric or missing Content-Length returns HTTP 400.
- Negative Content-Length returns HTTP 400.
- Bodies declared larger than 1 MiB (_MAX_BODY_BYTES) return HTTP 413,
matching the cap already in supervise_server.py.
Closes#138
BottleMetadata gains a backend field (default ""). Docker prepare writes
"docker"; smolmachines prepare writes "smolmachines". read_metadata
deserialises it with "" as the backward-compatible default.
resume now passes metadata.backend to _launch_bottle so a preserved
smolmachines bottle is resumed on the right backend without requiring
BOT_BOTTLE_BACKEND to be set manually.
_bottle_for_slug now reads metadata.backend and constructs a
SmolmachinesBottle for smolmachines slugs instead of always defaulting
to DockerBottle. No-metadata slugs still fall back to Docker.
Closes#137
apply_capability_change is Docker-only teardown/apply code. Before this
change it was called regardless of backend, so approving a capability-block
proposal from a smolmachines agent would run Docker commands against a
slug that has no Docker container.
After this change approve() reads the bottle's metadata: if compose_project
is empty (the smolmachines indicator) it raises CapabilityApplyError with
a clear operator message before any teardown runs. Docker bottles (non-empty
compose_project) and unknown bottles (no metadata) fall through to the
existing Docker path unchanged.
Closes#136
Before this change smolmachines prepare.py spliced bottle.env directly
into guest_env, so ?prompt and ${HOST_VAR} entries reached the VM as
raw sentinels rather than being prompted or interpolated.
After this change prepare.py calls resolve_env(), matching the Docker
backend's contract. Forwarded (secret/interpolated) values still flow
through smolvm -e K=V argv — the known exposure gap documented in PRD
0038's open question.
Closes#135
die() raises Die(SystemExit), which implies a process exit. A timeout in
wait_exec_ready is a bringup failure — raising SmolvmError lets the caller
decide whether it's fatal, consistent with how machine_start failures propagate.
