RenameCollectionNodes now reads geo info from cached egress-probe fields (country, countryCode, city, flag) on each node instead of doing per-node DNS lookups via DetectGeoWithServer.
When no cached egress data is available (probe not yet run), it falls back to name-based regex only (DetectGeo, no DNS) so the UI is never blocked. The background egress probe (triggered on source create/update) populates the cache asynchronously.
Also: runEgressProbe now stores countryCode and flag emoji from ipwho.is response. egressCacheKey and addCachedEgressInfo updated to include the new fields.
Reverted previous name-first hack on DetectGeoWithServer and DNS cache on geoip.LookupHost — no longer needed since rename doesn't call them.
Collection preview with rename: 30s -> 52ms (with cache miss, name-based fallback).
DetectGeoWithServer was doing GeoIP-first (DNS lookup per node) then falling back to name regex. For a 148-node collection with rename enabled, this meant 148 serial DNS queries in the rename pass alone (28s on slow DNS).
Reverse the priority: try name-based regex first (instant, no I/O), only fall back to GeoIP+DNS when the node name has no recognizable country keywords. Most proxy names already contain country/city info.
Also add in-memory DNS cache in geoip.LookupHost so repeated lookups for the same hostname don't re-resolve.
Collection preview with rename: 30s -> 3s.
- Add MaxMind GeoLite2-City mmdb auto-download and IP-based geo lookup
(covers all 249 countries globally, replacing limited 8-country regex)
- Add RenameOptions with 5 toggleable fields (flag/alias/country/city/index)
stored as rename_options_json on collections
- Collection rename pipeline uses DetectGeoWithServer(name, server) which
tries GeoIP lookup first, falls back to name-based regex matching
- Chinese country/city names + emoji flag prefix
- Country-city dedup: skip city when it equals country (e.g. 香港/香港)
- URI fragment encoding: url.QueryEscape -> url.PathEscape (%20 not +)
- Egress cache key excludes name field so renamed nodes still match cache
- Frontend: 5 toggle buttons in collection edit form, default all on
- Migrations: 0004 (source alias + collection rename_enabled),
0005 (collection rename_options_json)
