The designer's data model lives in internal/labels: STOCKS are the physical
roll in the printer (geometry in mm, margins, dpi — seeded with the common
Brother DK sizes, the QL family being what prompted the feature), TEMPLATES are
one design each, of two kinds: the QSO label glued on the card, whose repeating
table carries several contacts of the same station, and the address label for
the envelope, whose lines collapse when a variable is empty.
Everything is measured in millimetres — labels are sold in mm, and an operator
lining a design up against a physical sticker thinks in mm; pixels exist only in
the renderer, at the stock's dpi. The canvas renderer is shared between the
editor's preview and the future print path, so there is no second
implementation for the preview to disagree with.
The preview is fed with the log's latest contacts rather than lorem ipsum: real
data shows a too-narrow column immediately.
Printing (PDF, one page per label at exact size) is the next module; nothing
here prints yet.
Ultrabeam on a serial port never worked, and three faults were stacked so
each hid the next:
- Stop() did not wait for the poll loop, so a stopped client kept the COM
port. Every later client then failed with "Serial port busy" — the
program holding it being OpsLog itself.
- startUltrabeam tore the old client down CONCURRENTLY with starting the
new one, and "Test connection" built a second client on a port already
ours. Harmless over TCP, fatal on a port with one owner.
- A silent serial port returns (0, nil) and bufio retries that a hundred
times: a 4 s timeout became ~7 minutes of a frozen poll loop logging
nothing.
The controller then answered at once. Confirmed on hardware: the USB cable
presents TWO COM ports, only the second reaches the controller, and only at
19200 baud — so the speed is pinned in code (an FTDI cable opens at any
speed, and a wrong one is indistinguishable from a dead controller) and the
port field says which one to pick. The first exchange after each connect is
hex-dumped, which separates silence from a wrong baud from a misread frame.
Databases now carry only the tables their role needs. Every target used to
get the whole migration set, so a shared MySQL logbook grew settings and
station_profiles tables nothing ever wrote to — an operator inspecting the
server could not tell which copy was authoritative. Statements are filtered
by role, unknown tables are kept in both (fail-safe), and existing databases
are cleaned once, dropping only EMPTY tables. Settings → Database gains a
Compact button, since SQLite frees pages inside the file and never shrinks it.
Also:
- Awards: the callsigns behind a cell open the QSL Manager on Paper QSL,
searched, ready for the card dates.
- The record button no longer goes missing after an update: whether manual
recording is possible is a per-profile question that was asked once, at
startup, before the profile was known.
- Alert rules and filter presets confirm that they were saved.
- Spot clicks on the radio panadapter carry the POTA park into F3.
- The build gate is re-checked wherever the active callsign can change; it
ran at startup alone, and a fresh install has no callsign then.
