📝 Walkthrough

Walkthrough

Adds GeoIP support: new GeoIPResolver using a GeoLite2 DB; config adds GEOIP_DB_PATH; Anonymizer accepts an optional resolver and performs geo resolution; main wires resolver lifecycle; Docker/CI include the DB artifact; tests updated accordingly.

Changes

Cohort / File(s)	Summary
Env & Config .env.example, internal/config/config.go	Added GEOIP_DB_PATH to .env.example; ProcessorConfig and LoadProcessorConfig() now include GeoIPDBPath sourced from GEOIP_DB_PATH.
GeoIP Implementation & Tests internal/processors/geoip.go, internal/processors/geoip_test.go	New GeoIPResolver type with NewGeoIPResolver(dbPath), Resolve(ip) (country,region), and Close(); tests added validating public, private, and invalid IP behaviors using data/GeoLite2-City.mmdb.
Anonymizer & Tests internal/processors/anonymizer.go, internal/processors/anonymizer_test.go	NewAnonymizer signature now accepts (*GeoIPResolver); Anonymize attempts geo resolution when resolver present; tests updated to pass nil in call sites.
Main wiring cmd/processor/main.go	Main initializes GeoIPResolver from config, aborts on init error, defers Close(), and injects resolver into Anonymizer.
Module deps go.mod	Added direct dependency on github.com/oschwald/geoip2-golang/v2 and adjusted redismock entry.
Build, CI & Ignore Dockerfile, .gitignore, .github/workflows/ci.yml	Dockerfile copies data/GeoLite2-City.mmdb into image; data/ added to .gitignore; CI step added to download/extract GeoLite2 City DB using MAXMIND_LICENSE_KEY.
Test Call Sites internal/consumer/consumer_test.go, internal/pipeline/pipeline_test.go	Updated tests to construct anonymizer with NewAnonymizer(..., nil) to match new signature.

Poem

🐰 I hop through bytes and city maps tonight,
I sniff an IP, then tuck its trace from sight.
I fetch a country, whisper region low,
I hash the rest where only carrots know.
