Assigning over a day somebody else held did nothing but flash a 409 for
three seconds. The server holds one person per date and refused any that
was taken, all-or-nothing, so pressing W on a week where a single day was
already assigned placed none of the other six either. The only way
through was d on each day first — seven delete-and-confirm cycles to move
one week.
The clash is already on screen, so it is found before the request rather
than read back out of an error: the picker hands off to a confirmation
naming who loses the days and how many there are, and accepting sends the
whole selection with replace, which terdut-server v0.8.0 added. One
question to move a week, and nobody's shift moves without somebody being
asked. A day nobody holds still assigns with no prompt at all.
Reassigning somebody to a day they already hold raises no prompt, since
it takes nothing from anyone, but it does send replace: the server
rejects any date that exists, so without it a harmless no-op would fail.
terdut-server pages the on-call person through ntfy, but none of it was
reachable from here. A user's topic could only be set with curl, so a
new user silently got no pages and quietly fell back to the shared
fallback topic — which carries no Acknowledge button. And nothing said
whether anybody had been paged at all.
The Users section grows an Ntfy Topic column and t to edit it,
prefilled with the current value. Submitting an empty field clears the
topic rather than being rejected as a mistake: clearing is how somebody
is taken off their own topic, and it is what the server means by an
empty string. Nil and empty arrive as the same thing, because the
server stores a blank topic as NULL, so User.Topic flattens the two
instead of leaving every caller to.
The incident timeline renders the server's notified and notify_failed
events. No new fetch — the timeline endpoint already carried them, and
unknown types already fell through to a generic label; this is about
saying something useful. An event with no user means the fallback
topic, not "the server acted", which is the difference between somebody
having been paged and the rota having been empty.
Both need terdut-server v0.6.0 or later, and the timeline entries a
server newer than that. Against an older one the column stays empty and
editing a topic reports the server's 404, which is the honest answer.
Stats was the one full-screen view reached by a key of its own rather
than by tab, and the interface was less coherent for it. It is now a
section sitting third, after Alerts, and behaves like every other one:
tab in, tab out, r to refresh.
Three things fall out of the move. It auto-refreshes for the first time
— the tick handler skips every non-dashboard mode, which is why the
overlay never updated while it was open. Its error path no longer forces
the queue back into view on a failed fetch, an assumption that only made
sense while stats floated above the dashboard. And first-visit loading
keys off a statsLoaded flag rather than slice emptiness, because the
three empty slices a quiet server returns are a real answer, not a
missing one; the loading placeholder is likewise suppressed once
something has been drawn, so a background refresh cannot blank the page
out from under whoever is reading it.
The S key is gone, and with it the ability to peek at statistics from an
open incident and land back on it. That round-trip was the only thing
statsReturnMode bought, and it was the whole reason stats needed a mode.
The repo had no tests at all, which the v0.4.0 rewrite made
uncomfortable: this client speaks terdut-server's REST API directly, and
a wrong path or method is invisible until somebody runs the binary
against a live server. That is exactly how it broke when the server split
alerts from incidents.
The Elm architecture makes most of this cheap to check without a
terminal. Update is (Model, Msg) -> (Model, Cmd), so keypresses can be
synthesised and the resulting model inspected; a nil command is a
readable assertion that the model decided to do nothing.
Three suites:
- client_test.go drives every incident endpoint against an httptest
stub that records method, path, query and body. Also covers the
filter query params, that a server error message survives into the
error the UI shows, that a 404 from the on-call endpoint is not an
error, and that omitted optional fields decode to zero rather than
failing.
- model_test.go covers the pure helpers: filter cycling, the snoozed
pseudo-status, duration formatting, row builders, and the column
width arithmetic that overflowed the terminal once already.
- update_test.go covers the rules worth protecting rather than
coverage for its own sake. Resolve prompts first and cancelling does
not act, since resolution is terminal server-side. A resolved
incident rejects all six workflow keys. Archiving refuses while an
incident is open. The note cursor walks notes only and wraps. Stats
returns to whichever view opened it. Modal states do not auto-refresh
underneath the user.
129 tests, running in about 40ms.
