This commit pulls the spinner out of the header bar -- and
reincorporates it as a component that hooks into local state when
awaiting a new prop, or disabling an input.
In the wild, ships that were live pre-OS1 still had launch subscriptions
open to the clock on the /tile path, instead of the currently-used
/clocktile path. Additionally, launch state for the clock tile seemed
incomplete.
Here, we simply re-%add the clock to launch.
Note that launch currently does not clean up old subscriptions on
path change. For the pre-OS1 case, the old path is no longer in use,
rendering the subscription harmless. For cases where the correct
subscription was already in place, it'll print a %watch-wire-not-unique,
but doesn't do any harm besides that.
Previously, when the refresh-rate timer activated, and the thread from
the previous activation was still running, we would kill it and start
a new one. For low refresh rates, on slower machines, nodes, or network
connections, this could cause the update to never conclude.
Here we add a timeout-time to eth-watcher's config. If the refresh-rate
timer activates, and a thread exists, but hasn't been running for at
least the specified timeout-time yet, we simply take no action, and wait
for the next refresh timer.
Note that we opted for "at least timeout-time", instead of killing &
restarting directly after the specified timeout-time has passed, to
avoid having to handle an extra timer flow.
In the +on-load logic, we configure the timeout-time for existing
watchdogs as six times the refresh-rate. We want to set
azimuth-tracker's timeout-time to ~m30, and don't care much about other,
less-likely-to-be-active use cases of eth-watcher.
During the #2607 upgrade, strictly local collections got left out of the
listening set. (Because they did not have any outgoing subscriptions.)
This led to personal collections not being available on the frontend.
Here, we add upgrade logic for adding those back to our listening set again.
If a user had explicitly left a personal collection (instead of deleted it, for
whatever reason), they will have to leave it again. This case seems much more
rare than the "my collection is gone" one.
(Re)subscribing gets us a %contacts update, containing the full set of
contacts as it currently exists.
Previously, we would fully delete our local state, only to recreate it
using the data from the update.
Now, we never delete existing data, instead only creating if we don't
have it yet, and adding, removing or recreating contacts if they
changed.
In the future, we'll want an easy way to turn two contacts into an %edit
diff, to let us apply correct semantics to individual contacts, too.
Instead, %bundle and %add if we don't have the group locally yet,
or %add and %remove whatever the difference is between the local group
and the group as specified in the %path update.
