Every BreadEvent now gets a unique id at construction (via
BreadEvent::new/with_timestamp, and the normalizer's struct-literal call
sites, which all now assign one explicitly). A new caused_by field is
populated only when a Lua bread.emit() call runs synchronously inside a
bread.on subscriber's handler: LuaEngine tracks the currently-dispatching
event's id (set/restored around each handle_event invocation, single-
threaded so a plain Mutex-guarded slot suffices) and bread.emit()'s Rust
binding reads it when constructing the outgoing event. This lets chains of
Lua modules that react to each other's events be reconstructed instead of
timestamp-guessed from a live `bread events` log.
Also:
- bread events --tree renders the caused_by chain as an indented,
live-streaming-friendly tree instead of a flat line-per-event stream.
- API_VERSION bumped 1.4.0 -> 1.5.0 (additive-only change).
- Documentation.md's event envelope, bread.emit, and debugging-tips
sections updated with Since: v1.5 markers.
- New end-to-end regression test spawning the real daemon with 3 chained
Lua handlers (A emits X on trigger, B emits Y on X, C emits Z on Y) and
asserting caused_by threads correctly through all three hops.
P1-A: normalizer derives `online` from rtnetlink event kind (link.up/down,
route.default.changed, address.added/removed) so bread.network.connected
fires correctly on all systems using rtnetlink.
P1-B: stream_events consumes the subscribe ack before the event loop so the
first line is not printed as garbage.
P1-C: UPowerAdapter::probe() validates D-Bus synchronously before committing;
the sysfs fallback now actually triggers when D-Bus is unavailable.
P2-A: profile.list returns the full profile state (active + history) instead
of the always-empty profiles map.
P2-B: profile history capped at 50 entries in both StateCommand and
apply_event_to_state to prevent unbounded growth.
P2-C: RtnetlinkAdapter::new() no longer spawns an orphaned tokio task;
it validates availability by constructing and immediately dropping the
connection tuple.
P2-D: Lua-side hyprland_request_socket() logs a warn when multiple
Hyprland instances are found, matching the adapter-side behaviour.
P2-E: Malformed JSON from an IPC client returns an error response and
continues rather than closing the entire connection.
P3-A: Remove the `ends_with(".*")` prefix-match shortcut from both the
subscription table and the IPC event filter. `bread.*` now means
one segment (matching documented API semantics: `* = one segment`).
Tests updated accordingly.
P4-A: Remove unused `git2` and `glob` workspace dependencies (left over
from bread-sync extraction).
P4-B: breadd dev-dependency `tempfile` declared via workspace = true.
P4-C: Remove unreachable XDG_CONFIG_HOME branch in modules_dir(); dirs
already reads that var internally before returning None.
P4-D: Delete duplicate send_request_with_stream(); print_doctor() now
uses socket.exists() + send_request() directly.
P5-A: release.yml drops `--lib` from cargo test so integration tests run
in the release gate.
P6-A: bluetooth_spawn / bluetooth_query replace expect() on tokio runtime
construction with error logging / error propagation.
P6-B: Spin loops in lua/mod.rs add std:🧵:yield_now() after the
PAUSE hint to reduce CPU burn under sustained RwLock contention.
P6-C: All Mutex::lock().expect("... poisoned") in lua/mod.rs replaced with
unwrap_or_else(|e| e.into_inner()) for poison recovery.
P7-B: bread.system.startup event moved from main.rs into ipc::Server::serve()
so it fires after the socket is bound (smaller race window for early
subscribers).
- Introduced a new mechanism in EventNormalizer to suppress duplicate events from child nodes of the same physical device.
- Removed the device classification logic from the normalizer and replaced it with a rule-based system using Lua scripts.
- Added support for user-defined device rules in Lua, allowing for flexible device naming based on various conditions.
- Updated the state engine to handle device rules and resolve device names before dispatching events.
- Modified the installation script to set up default configuration files for the daemon and Lua modules.
- Improved the handling of systemd user services to dynamically set the ExecStart path based on the installation directory.
