"""Background snapshot refresher — chantier B (0.22.0).
|
|
|
|
The expensive part of Kanbante is the fan-out of Gitea list
|
|
calls behind the portfolio pages (repo index, then issues and
|
|
milestones for every active project). Since 0.19.0 those calls
|
|
are parallel and stale-while-revalidate, which fixed repeat
|
|
loads, but the FIRST page after a restart still paid seconds.
|
|
|
|
The refresher pays that cost instead of the user: every
|
|
KANBANTE_SNAPSHOT_INTERVAL seconds it force-refreshes the hot
|
|
keys (repo index, starred, issues + milestones of active
|
|
repos). Every fetch write-throughs to the SQLite `snapshots`
|
|
table, and the client cache is hydrated from that table at
|
|
startup — so pages read local data from the very first request
|
|
and only ever wait on Gitea when no snapshot exists yet.
|
|
|
|
Freshness contract, shown in the UI: Gitea-side data may lag
|
|
by up to one interval; a Gitea webhook refreshes the touched
|
|
repo immediately (see refresh_repo_snapshots); anything the
|
|
user does locally (board journal) is always instant.
