Both found live while building gui/tests/dod's DoD harness, not from reading
the code — see that commit for how.
RpcClient::stop() left conn_ dangling after joining the worker thread: the
thread's own finish() flushes the DeferredDelete stop()'s
connect(&thread_, &QThread::finished, conn_, &QObject::deleteLater) already
posted, so conn_ is gone by the time stop() returns, but nothing cleared the
pointer. Any caller that calls stop() and later lets the client destruct
(the harness's own client.stop() at shutdown; also plain, correct API usage)
hit a double-free in the destructor's leftover `delete conn_`. Caught by
ASan on the very first run that actually exercised the stop-then-destroy
path.
requestInitialList() also called download.list with a hardcoded
`{"limit": 1000}`, silently capping the table at 1000 rows no matter how
many the daemon actually has — download.list.schema.json's own description
says "the GUI pages", not "the GUI takes it all in one call". The
scroll-60fps DoD gate refused to run against mockd --tasks 10000 rather
than "pass" against a 1000-row table, which is what surfaced it.
requestInitialList() now pages (5000 per call, the schema's own max) until
`total` is satisfied, then resets the model once with everything.
Separately: RpcConnection's session.subscribe list never included
event.settings.changed or event.grabber.progress, even though RpcClient has
carried signals for both since the Options/Grabber work — session.subscribe
"replaces the previous selection" and "nothing is delivered until this is
called", so both events were being silently dropped by any real daemon that
enforces the subscription (mockd does; verified live with a second
subscribed client actually receiving event.settings.changed after this
fix, round-tripped through a real veloxd's settings.set). GrabberWizard's
5 s poll fallback is exactly why this went unnoticed until now — it covered
for the missing push the whole time.
