Add _wait_for_gateway_exit() that polls get_running_pid() to confirm
the old gateway process has actually exited before starting a new one.
If the process doesn't exit within 5s, sends SIGKILL to the specific
PID. Uses the saved PID from gateway.pid (not launchd labels) so it
works correctly with multiple gateway instances under separate
HERMES_HOME directories.
Applied to both launchd_restart() and the manual restart path (replaces
the blind time.sleep(2)).
Inspired by PR #1881 by @AzothZephyr (race condition diagnosis).
Adds 4 tests.
Multiple Hermes installations on the same machine now get unique
systemd service names:
- Default ~/.hermes → hermes-gateway (backward compatible)
- Custom HERMES_HOME → hermes-gateway-<8-char-hash>
Changes:
- Add get_service_name() in hermes_cli/gateway.py that derives a
deterministic service name from HERMES_HOME via SHA256
- Replace all hardcoded 'hermes-gateway' systemd references with
get_service_name() across gateway.py, main.py, status.py, uninstall.py
- Add HERMES_HOME env var to both user and system systemd unit templates
so the gateway process uses the correct installation
- Update tests to use get_service_name() in assertions
Fixes#1005
Without linger, user-level systemd services stop when the SSH session
ends — even though systemctl --user status shows active (running).
Changes to systemd_install():
- Try loginctl enable-linger automatically (succeeds when the process
has the required privileges)
- If loginctl fails (no privileges), print a clear, copy-pasteable
warning with the exact command the user must run
New helper: _ensure_linger_enabled()
- Fast path: checks /var/lib/systemd/linger/<user> (no subprocess)
- Auto-enable: loginctl enable-linger <user>
- Fallback: actionable warning with sudo command + restart instructions
Tests: 4 new tests in TestEnsureLingerEnabled, 205 passed total
* fix(gateway): surface missing linger in status and doctor
Warn when a systemd user gateway service has linger disabled so users can
spot the common 'gateway sleeps after logout' deployment issue from both
hermes doctor and hermes gateway status.
* fix(gateway): check linger status after install
After installing the systemd user service, report whether linger is
already enabled instead of always printing the generic hint. This makes
post-install guidance match the user's actual deployment state.
