Critical:
- Remove :protected from WeatherCache ETS (conflicted with :public)
- Register Aprsme.ReplayRegistry in supervision tree
- Route :continue_replay dead message to :start_replay handler
- Add 5000ms timeout to unbounded :rpc.call calls
- Fix falsy lat/lng check rejecting valid 0 coordinates
Medium:
- Fix live_reload pattern (temp_web -> aprsme_web)
- Remove duplicate ecto_repos config
- Make DB SSL configurable via DB_SSL env var
- Track sizeCheckTimeout on self for cleanup in destroyed()
- Wrap pushEvent calls in try/catch
- Remove unused size variable in marker cluster icon
- Capture touch coords at touchstart instead of stale TouchEvent
- Demote console.log to console.debug in production code
- Add catch-all to normalize_bounds preventing GenServer crash
Style:
- Add missing @impl true annotations in is.ex
- Improve migration failure error message
- Use textContent instead of innerHTML for error messages
- Use proper type for longPressTimer instead of any
- Make LeaderElection check_interval, max_cluster_wait, and cluster_check_interval
configurable via Application env so tests can override with short values
- Slow LeaderElection tests now use 50-150ms timeouts instead of 3-6s
- Remove :slow tag from unused_test (compile cache makes reruns cheap)
- Drop :slow from test_helper exclude list
All 2490 tests now run in ~45s (up from 2485 with 5 excluded).
- get_cluster_aprs_status: fetch_cluster_status/1 dispatches on the
clustering flag — true fans out cluster-wide, false goes straight to
the local Aprsme.Is status.
- init/1: extract schedule_initial_election/1 with true/false heads.
The clustered branch sets up the check-and-backstop timers; the
non-clustered branch queues an immediate election. Makes the two
startup paths obvious from the function signatures.
No behavior change; all 17 LeaderElection tests still pass.
Converts the inline state maps in Is, PacketConsumer, LeaderElection, and
CircuitBreaker into structs with @type t specs. Enforced keys catch typos
on state updates and give dialyzer a concrete type to check against
instead of map() in every handle_* clause.
Is' nested login_params and packet_stats are extracted to their own
modules (Aprsme.Is.LoginParams, Aprsme.Is.PacketStats) rather than
defined inline, per the project's no-nested-modules rule.
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.
Dep upgrades (mix deps.update --all):
- phoenix_live_view 1.1.27 → 1.1.28
- swoosh 1.23.1 → 1.25.0
- bandit 1.10.3 → 1.10.4
- credo 1.7.17 → 1.7.18
- hammer 7.2.0 → 7.3.0
- igniter 0.7.6 → 0.7.9
- and minor: fine, lazy_html, meck, mimerl
- removed stale lock entries: geocalc, gettext_pseudolocalize, gridsquare
Bug fixes surfaced during update:
- ETS cache tables were :protected (owned by Application master), preventing
the Cache GenServer from writing; change to :public + write_concurrency
so device/symbol/query caches actually work
- historical_dot_html returned Phoenix.HTML.safe tuple instead of plain string;
symbol_html is JSON-encoded for JS so it must be binary
- String.slice always returns binary so the || "Unknown error" fallback was
unreachable dead code (dialyzer guard_fail)
- Supervisor.which_children always returns a list so the _ -> branch in
database_metrics was unreachable dead code (dialyzer pattern_match_cov)
- Add @type t :: %__MODULE__{} to User schema to resolve unknown_type in user_auth spec
- Extract nested if in leader_election to fix Credo nesting depth violation
- Update .dialyzer_ignore.exs: remove 2 stale entries, add false positives for
Ecto.Multi/Gettext opaque types and Mix.Task PLT limitations
ConnectionMonitor.gather_cluster_stats was calling :rpc.call(Node.self())
which GenServer.call'd back into itself while blocked in handle_info,
causing a 5-second deadlock timeout every 30 seconds. Fixed by computing
local stats directly from state.
LeaderElection never verified that a leader still held the :global
registration. After :global conflict resolution (two isolated nodes
merging), the loser was silently unregistered but stayed is_leader: true
forever, causing both pods to connect to APRS-IS with the same callsign
in a reconnect loop. Fixed by adding verify_leadership/1 to
check_leadership which detects lost registrations and steps down.
:global.register_name returns :no even when the name is already
registered to the calling PID. This caused the leader to clear its
own leadership state every 5 seconds after cluster formation triggered
a redundant re-election attempt.
Now checks if we already hold the registration before attempting to
re-register, preserving leadership state across cluster topology changes.
- Switch PacketProducer buffer from list to :queue for O(1) overflow handling
- Add cached leadership check via :persistent_term to eliminate GenServer.call
bottleneck in packet distribution hot path
- Simplify packets_live coordinate extraction from 70 lines of nested
conditionals to helper functions (extract_coordinate/2, format_coordinate/1)
- Remove debug logging from hot paths (packets.ex queries, PacketDistributor,
app.js console.logs)
- Remove sobelow dependency (false positives blocking commits)
- Add 25 new tests for PacketProducer, coordinate helpers, and cached leadership
Simplify complex functions to improve readability and maintainability:
- clustering.ex: Convert case statement to map lookup for cluster radii
- encoding.ex: Extract codepoint validation into separate function clauses
- leader_election.ex: Extract PID liveness checking and cleanup logic into helpers

Previously, when clustering was enabled, the leader election process
would wait indefinitely for the cluster to form. If cluster formation
failed or took too long, no leader would be elected and the APRS-IS
connection would never start, leaving the system disconnected.
Changes:
- Add 30-second timeout for cluster formation
- Force leader election after timeout, even in single-node mode
- Add election_forced flag to prevent duplicate election attempts
- Improve logging to distinguish between cluster and single-node modes
This ensures that at least one node will always connect to APRS-IS,
even if clustering fails completely.

Fixes compilation warning by moving the catch-all handle_info/2 clause
to be immediately after the specific handle_info/2 clauses.
In Elixir, all function clauses with the same name and arity must be
grouped together for pattern matching to work correctly.
This resolves the 'mix compile --warnings-as-errors' failure.
- Fix leader election guard test for :undefined pid
- Fix cpu_sup.util() pattern matching to handle numeric return
- Fix encoding_utils to always return explicit nil when needed
- Remove unused finite_float? function
- Fix signal handler to match :ok return from :os.set_signal/2
- Remove redundant catch-all pattern in database metrics
- Fix Gridsquare pattern matching in info_live template
- Remove unnecessary nil check for calculate_course result
- Fix get_packet_received_at to not check for nil (always returns DateTime)
- Remove redundant catch-all pattern in weather format_weather_value
- Fix query builder to use from(p in Packet) instead of bare Packet atom
Reduced dialyzer errors from 49 to 6. Remaining warnings are mostly
false positives from template compilation and overloaded function specs.

Both /status and /status.json endpoints now show cluster-wide APRS-IS
connection status instead of just local node status.
Features:
- get_cluster_aprs_status() checks all nodes in cluster via RPC
- Returns status from any connected node (usually the leader)
- Shows cluster info: total nodes, connected nodes, leader node
- Graceful fallback to local status in non-clustered mode
- Enhanced status page UI with cluster information display
This ensures status pages accurately reflect the true APRS-IS
connection state across the entire cluster.

The cleanup_stale_registrations function was calling Process.alive?
on remote PIDs, which causes an ArgumentError. Fixed by:
- Using Process.alive? only for local PIDs
- Using :rpc.call for remote PID liveness checks
- Adding proper error handling for RPC failures
- Cleaning up registrations for disconnected nodes
This prevents GenServer crashes when checking leader status.

- Leader election now waits for other nodes to connect before starting
- Added cleanup of stale global registrations from disconnected nodes
- Only starts election after cluster is established in clustered mode
- Non-clustered mode continues to elect immediately
This prevents both nodes from becoming leaders when they start
before the cluster is fully formed.

The previous conflict resolution tried to call Process.info/2 on remote
PIDs, which doesn't work. Changed to use node name comparison for
deterministic leader selection across the cluster.
This ensures only one leader is elected when nodes join the cluster.

multiple Kubernetes replicas. This prevents duplicate packet processing
and respects APRS-IS usage policies.
Key changes:
- Add leader election using :global registry
- Create connection manager for dynamic APRS-IS management
- Implement packet distribution from leader to all nodes
- Add Kubernetes headless service for node discovery
- Configure DNS-based clustering with libcluster
- Update deployment to support 3 replicas with clustering
