The full-system updater runs as a detached systemd service and can finish
successfully even when the browser loses its status connection. In that
case the update log and status file correctly report REBOOT_REQUIRED, but
the Hub modal can remain on "Updating..." with its controls disabled.
There were four independent ways for the frontend to get stuck:
* update status fetches had no deadline, so a request that stayed pending
never rejected and never advanced the existing failure counter;
* setInterval started async polls without waiting for the previous poll,
allowing slow requests to overlap and responses to arrive out of order;
* each log chunk used textContent +=, replacing the complete and growing
Nix build log every two seconds, which could stall browser rendering and
was especially visible over RDP; and
* page reload, tab resume, and RDP reconnect did not reattach the modal to
the update status persisted by the backend.
This produced a dangerous UX mismatch: the machine had a fully staged
NixOS generation and was ready to reboot, while the Hub continued telling
the user that the update was still running.
Bound status requests with AbortController, prevent overlapping polls, and
replace the endless spinner after sustained failures with an explicit
"Update status unavailable" state and Retry Status action. Reconcile state
immediately on focus, visibility, online, page startup, and before starting
a new update. Use no-store requests and render verbose logs incrementally
with a bounded visible tail while retaining the complete report in memory.
Apply the same timeout and single-flight protection to rebuild polling.
Record the exact generation produced by `nixos-rebuild boot`. The Hub now
keeps REBOOT_REQUIRED visible until that generation matches
/run/current-system, then clears the marker after reboot. For an update
started by an older updater that did not write the marker, recover the
staged generation from the final nixos-rebuild log line. The dashboard
sidebar also distinguishes update-in-progress and restart-required states.
Regression coverage verifies generation marker/log recovery, pre- versus
post-reboot detection, request timeout wiring, single-flight polling,
connection-loss UX, RDP/tab resume reconciliation, bounded log rendering,
page-reload recovery, and JavaScript syntax.
Validation:
* python3 -m unittest discover -s tests -p 'test_*.py' -v (170 passed)
* node --check app/sovran_systemsos_web/static/js/*.js
* python3 -m py_compile for changed Python modules
* git diff --check
A Nix evaluation was not available in the development sandbox; the NixOS
module should still be evaluated and built in CI or on a test machine before
release.
The LND-only rewrite of lndconnect.nix shipped a wrapper Zeus cannot
use: unknown flags (--cert/--macaroon), a non-existent onion path
(free/lnd.onion), and a REST hidden service that collided with LND's
P2P onion. Restore the nix-bitcoin contract — dedicated lnd-rest
onion on port 8080, --nocert over Tor, admin macaroon in the URI —
and only persist a valid lndconnect:// URI for the Hub QR.
The Hub launcher used an ephemeral /tmp profile deleted on exit, which
wiped the hub_manual_logout marker cookie. On reopen, /auto-login minted a
new session and logged the user straight back in without a password.
Use a persistent per-user profile under XDG_STATE_HOME and drop the
deletion trap so the logout marker survives close/reopen. Keep
--skip-origin-startup-dialog. Adds regression tests.
- Add btcexplorercookiefile to BTCPay deterministic config so NBXplorer
cookie authentication succeeds (fixes 401 Unauthorized)
- Set WorkingDirectory to package lib dir so ASP.NET Core can locate
wwwroot and LanguageService.ctor does not throw ArgumentNullException
- Update regression test to assert cookie file path and WorkingDirectory
