- IS GenServer: add missing :failure_started_at to test build_state/1 map
- IS GenServer: fix stale status server assertion and reconnection test
- IS GenServer: set Logger level to :debug for dispatch parse-error tests
- PacketReplay: remove conflicting Registry start_supervised! from setup
- PacketReplay: update assertion from {:continue_replay} to :start_replay
- Doctests: fix float precision, stale sprite coords, quoting escapes
- API controllers: use string keys for JSON error/postion details
- PacketUtils: fix operator precedence (not is_nil(result).field)
- ThemeManager: update expected dark theme text color
- StatusLive: remove/update stale :loading assign assertions
- Movement: remove {:ok, _v} wrapper from render_hook/3 (returns HTML)
- AprsIsMock: update packet_stats assertion for populated default shape
- consolidate Haversine: CoordinateUtils delegates to GeoUtils;
InfoLive.haversine/4 reuses it (m -> km)
- AprsSymbol: collapse 3 sprite-info builders onto build_sprite_info/2
and add a sprite_info @type
- DataBuilder: 3 weather unit converters share convert_unit/4 with
explicit clauses for "N/A", numeric, and binary inputs
- mobile_channel: do_callsign_match/2 uses pattern-match clauses for
wildcard handling instead of nested if
- info_live: replace nested case in position_changed? with multi-clause
coords_changed?/1; format_timestamp_for_display pipelines into a
guarded build_timestamp_display/1
- api_docs_live: collapse chained single-key assigns into keyword-list
assign/2 calls
- add strict @spec coverage on all touched helpers; tighten new specs to
match dialyzer success typing (no contract_supertype warnings)
- Three-way cond (known-table / overlay-capable char / fallback) becomes
three function heads: a guard-matched clause for the canonical
"/"/"\\"/"]" tables, an is_binary clause that decides via regex match
whether the input is a single alphanumeric overlay character, and a
catch-all fallback.
Turned on :error_handling, :underspecs, and :unmatched_returns in
mix.exs dialyzer config. The 97 warnings this surfaced were fixed in
place rather than suppressed:
- unmatched_return (79): explicit discard with `_ = ...` for
fire-and-forget side effects (Process.cancel_timer, :ets.new,
send/2), and pattern-matched `:ok = ...` for control-plane
Phoenix.PubSub subscribe/unsubscribe/broadcast calls so a future
return-shape change fails loud.
- contract_supertype (18): tightened @spec arg and return types on
data_builder, historical_loader, url_params, packet_utils,
encoding_utils, aprs_symbol, weather_controller, packet_replay to
match each function's actual success typing.
No behavioural change. mix compile clean, 1008 tests pass, dialyzer
count is now 0.
Replace case/cond/if blocks with multi-clause function dispatch
and pattern matching in function heads across 9 modules:
- WeatherUnits: case to multi-clause unit_system/1, unit_labels via do_unit_labels/1
- PacketUtils: if to pattern match on %{"id" => id}, multi-clause threshold/callsign
- SetLocale: case to multi-clause extract_locale/1
- IPGeolocation: if/cond to pattern match on conn, binary prefix matching for private_ip?
- DeviceIdentification: cond to extracted pattern_matches?/2
- MobileChannel: cond to multi-clause do_callsign_match/2
- PacketProcessor: cond to dispatch_visibility/6 on {in_bounds, has_marker} tuple
- PacketManager: destructure packet_state in heads, multi-clause maybe_cleanup/3
- AprsSymbol: case/if to multi-clause get_table_id/1, normalize_symbol_code/1
This commit introduces a dual-mode caching and rate limiting system that can use
either Redis (for distributed deployments) or ETS/Cachex (for single-node setups).
Key changes:
- Add Cache abstraction layer that automatically switches between Redis and Cachex
- Implement RedisCache module with full distributed cache functionality
- Implement RedisRateLimiter with sliding window algorithm for accurate rate limiting
- Add RateLimiterWrapper to provide unified API for both implementations
- Update application startup to conditionally use Redis when REDIS_URL is set
- Migrate all cache operations to use the new Cache abstraction
- Support graceful fallback to ETS-based solutions when Redis is unavailable
The system automatically detects Redis availability via REDIS_URL environment
variable and switches between implementations without code changes. This enables
proper distributed caching and rate limiting in Kubernetes deployments while
maintaining backward compatibility for development environments.
