Extract the file/git/httpcache mode switch into newSource and the Group
wiring into newBlocklists. main becomes flag parsing + exit code logic
only; run owns ctx and the check. Helpers (loadCohort, cacheDir,
splitCSV, loadWhitelist) are small and single-purpose.
Still exercises dataset.Group + background refresh, gitshallow, and
httpcache as before.
OpenDatabases(confPath, cityPath, asnPath) handles conf discovery, cache
dir setup, and Databases construction. DefaultConfPaths lists the standard
GeoIP.conf locations. cmd/check-ip/geo.go deleted; main calls one function.
Remove View[T] — Add now returns *Dataset[T] directly. Callers use Load()
on the returned Dataset; Init/Run belong to the owning Group.
main.go simplified: declare syncer + file paths per case, then one
g.Init() and one g.Run(). No manual loops over individual datasets.
Add gitshallow.Repo.FilePath helper.
Blocklist:
- Add -inbound, -outbound, -whitelist flags for explicit file paths
- buildSources() replaces the old constructor trio; explicit flags always win
- -data-dir and -git still work as defaults for the bitwire-it layout
GeoIP:
- Auto-discover GeoIP.conf from ./GeoIP.conf then ~/.config/maxmind/GeoIP.conf
- If no conf found and no -city-db/-asn-db given: geoip disabled silently
- If no conf but paths given: use those files (Init fails if absent)
- Each package gets its own go.mod: net/{dataset,httpcache,gitshallow,ipcohort,geoip,formmailer}
- go.work with replace directives for cross-module workspace resolution
- dataset.Syncer/NopSyncer moved here from httpcache; callers duck-type it
- dataset.View[T] returned by Add to prevent Init/Sync/Run misuse on group members
- cmd/check-ip moved from net/ipcohort/cmd/check-ip to top-level cmd/check-ip
- Add net/ipcohort/cmd/ipcohort-contains for standalone cohort membership testing
