## Prompt
|
||
|
|
|
||
|
|
The human chose to defer multiprocessing bindspace FD transport because
|
||
|
|
that backend may be removed, selected root/single-actor namespace
|
||
|
|
bootstrap as the next stage, approved caller-thread restoration and
|
||
|
|
public `tractor.net.open_wg_bindspace()` composition, and authorized
|
||
|
|
implementation after the stack rebase.
|
||
|
|
|
||
|
|
## Response summary
|
||
|
|
|
||
|
|
Added `bindspace=` to `tractor.open_root_actor()`. Root startup now
|
||
|
|
duplicates and validates the live namespace FD, enters before any
|
||
|
|
debugger, registry, IPC, or actor-runtime work, and synchronously
|
||
|
|
restores the caller thread's original namespace after complete root
|
||
|
|
teardown. Added deterministic failure/cancellation coverage, a real UDS
|
||
|
|
root actor E2E across two network namespaces, and an executable public
|
||
|
|
WireGuard-bindspace/root composition regression. Bound roots reject the
|
||
|
|
persistent `mp_forkserver` backend because a helper from an earlier
|
||
|
|
runtime may retain a stale namespace; the public annotation also remains
|
||
|
|
runtime-resolvable without importing `tractor.net` eagerly.
|
||
|
|
|
||
|
|
## Files changed
|
||
|
|
|
||
|
|
- `tractor/_root.py` - public root bindspace lifecycle integration.
|
||
|
|
- `tractor/spawn/_netns.py` - temporary thread-local netns enter/restore.
|
||
|
|
- `tests/test_netns_spawn.py` - deterministic and real root regressions.
|
||
|
|
- `tests/net/test_wg_iface_lifecycle.py` - public root composition test.
|
||
|
|
- `docs/api/net.rst` - root ownership and restoration contract.

## Human edits
|
||
|
|
|
||
|
|
The human explicitly deferred multiprocessing support, selected root
|
||
|
|
bootstrap as the next implementation stage, approved the requirement to
|
||
|
|
restore the caller's original namespace so owned teardown can complete,
|
||
|
|
and approved composition through public `tractor.net` contexts rather
|
||
|
|
than a new one-shot convenience API. The human later rewrote
|
||
|
|
`_enter_netns_temporarily()` to separate restoration from FD cleanup and
|
||
|
|
make the transition flow easier to inspect. The agent retained that
|
||
|
|
intent with nested lexical FD ownership while fixing setup-error masking,
|
||
|
|
conditional restoration, and duplicate-FD cleanup found during the
|
||
|
|
requested audit.
