Reported by an operator whose node sends little: nothing for two minutes, then a
reconnect — losing the login, the filters, and any spot that arrived during the
gap.
The read had a 120 s deadline and ANY error ended the session, a timeout
included. That reads a silence as a verdict on the link. It is not: a cluster on
a dead band legitimately says nothing for minutes.
Only a real error ends a session now. A genuinely dead peer is still caught, and
by the mechanism meant for it — TCP keepalive probes an idle connection and its
failure surfaces as an error on Read, not as a timeout. The dialer sets it
explicitly rather than inheriting a default, since it is now what the design
depends on.
One trap the advice this came from did not mention: ReadString returns the bytes
it HAD read along with the timeout. Discarding them would lose the first half of
any spot line straddling a deadline, so the partial is carried over.
Tested: a listener that goes silent past the deadline and then sends a spot —
the spot arrives on the ORIGINAL connection, and the listener never accepts a
second one. The tick is a var so that test runs in four seconds instead of
sixty; a slow test is a test that gets skipped.
Reported on 3 cm. cat.BandFromHz stopped at 23 cm, so a 10 GHz frequency came
back EMPTY — and an empty band is not cosmetic: the QSO is logged without one,
counts in no award slot, and exports with no BAND field. The low end was short
too (2190m / 630m / 560m).
Four band tables had to be extended because four exist: the CAT one, the award
plan in app.go, the cluster spot classifier, and the frontend's. Plus the places
that LIST bands — the QSO editor and award-definition pickers (you could not set
3 cm by hand either), the statistics axis, and the award band ORDER, where a
missing band sorts to the end instead of in frequency order.
Ranges and names are ADIF 3.1.7, which is what an export has to carry.
A test now pins one frequency per band across the Go tables and asserts they
agree — that is what was missing, four hand-maintained copies with nothing
checking them. It also pins that an out-of-band frequency stays empty rather
than snapping to the nearest band, which would file a QSO under a band the
operator never used.
