The smoke test only exercised steady-state rendering and killed waybar with
SIGTERM, so whole crash classes were invisible: exit-time use-after-free
(#5182), module state transitions (#5183) and hardware-backed modules (#5179).
Add tiers that hit those paths under ASan (+ _GLIBCXX_ASSERTIONS):
- lib.sh: assert_clean_exit (SIGINT teardown -> checks segfault/abort + ASan
report emitted during destruction), output hotplug helpers, signal/reload,
WAYBAR_WRAP hook, opt-in leak detection.
- lifecycle.sh (gating): clean exit, runtime output hotplug (Bar/module
destroy), toggle/reload churn, fast-interval teardown race (#5182 class).
- fuzz.sh (gating): pathological custom-backend output (empty, nonzero exit,
invalid JSON, huge, non-UTF8, empty format).
- coverage.sh (gating): every Factory module must be classified for smoke
coverage; a new unlisted module fails the job (#5179 slipped through).
- modules.sh: also render the whole matrix inside a group; SIGINT teardown per
module instead of SIGTERM.
- state.sh (best-effort): real mpd driven through an empty queue (#5183) +
stop/clear; pulseaudio + slider on a null sink.
- hardware.sh (best-effort): backlight, backlight/slider (#5179) and battery
via umockdev.
- leakcheck.sh (report-only): clean-exit run under LSan.
Turn the smoke test into a real runtime safety net. Waybar is now built with
AddressSanitizer and exercised end to end in a headless compositor:
- Tier 0: run everything under ASan; fail on ASan reports and Gtk/GLib
criticals in the log (lib.sh assert_clean)
- Tier 1: per-module render matrix (modules.sh) — each headless-safe module
rendered in isolation
- Tier 2: pointer interaction (interact.sh) — inject clicks via sway, assert
on-click side effect and format-alt toggle; AT-SPI assertions (a11y.sh/.py)
check module labels semantically instead of by pixels
- Tier 3: layout matrix (positions.sh) — top/bottom/left + HiDPI scale 2;
second compositor run under labwc
Shared helpers extracted to lib.sh. Adds a workflow_dispatch `bless` input to
regenerate the golden reference in one click. Trigger push only on master to
avoid duplicate PR runs. AT-SPI and labwc steps are continue-on-error.
Extend the pow_format spec parser beyond alignment so configs can shape the
rendered number, not just pad it. A forced scale (#, k, M, G, T, P) pins the SI
prefix instead of auto-selecting it and, since the author then knows both scale
and unit, hides the prefix and unit by default; U brings the unit back, u hides
it in auto mode, and i forces integer display. b and B override the decimal or
binary base independently of the call site, and a trailing width now fixes the
coefficient field when a scale is forced, overflowing to '#' when it does not
fit.
The old '>' and '<' branches rendered via fmt::format("{}", s), which discarded
every new field on the recursive call; they now build from a single render path
that reads the current formatter, so modifiers survive alignment. The auto path
is byte-identical to before, verified against the previous implementation.
Adds a Catch2 suite covering each modifier alone and combined, plus the
backward-compatible alignment cases, and documents the modifiers in the network
and disk man pages.
Run clang-format on the changed C++ files and fix the clang-tidy findings introduced by the custom command migration.
The only codegen-relevant change here is switching the new res assignments in custom.cpp to designated initializers. The rest is formatting only.

Add focused coverage for the new GLib command stream helper.
These tests verify that complete lines are emitted as they arrive and that EOF flushes a final unterminated line without duplicating a newline-terminated one.
That behavior is the contract the custom module will rely on when its continuous command handling moves onto this helper.

Blessed from the CI artifact of the passing headless run (Waybar / CI smoke
test / 12:34 on a pinned DejaVu Sans bar). Regenerate from a new artifact when
an intended visual change trips the comparison — see test/smoke/README.md.
The static custom modules used `exec: echo` (empty output), so the modules
rendered nothing and the bar strip was blank. Have exec print the label text
and use the default `{}` format.
Launch the real Waybar binary inside a headless, software-rendered sway
compositor and verify it actually runs and renders — something the unit
tests and build jobs never do.
- test/smoke/run.sh: boots sway (WLR_BACKENDS=headless, pixman), starts
waybar, asserts it stays alive with no fatal log, optionally grabs a
screenshot with grim
- level 1: real modules (clock/cpu/memory/disk) load without crashing
- level 2: deterministic config is screenshotted and checked to be non-blank
- level 3: screenshot compared to test/smoke/reference.png (fuzz 8%,
800px tolerance); screenshot + diff uploaded as artifacts
- .github/workflows/smoke.yml runs it on push/PR
The reference image must be blessed from a CI artifact (see test/smoke/README.md).

Move buildLuaDispatch and isLuaProtocol from private to
protected/public so IPCTestHelper can access them.
Add 7 tests covering all buildLuaDispatch branches, dispatch
error path, and isLuaProtocol cache behavior.
The Hyprland IPC helper cached the socket folder with the first instance
signature already appended, so later calls ignored their instanceSig argument
and always reused the first path. That made the helper violate its own API even
though most real Waybar sessions only talk to a single Hyprland instance.
Cache only the base socket directory and append the requested signature per
lookup. This fixes correctness for tests, nested or debug multi-instance
setups, and future code that needs to resolve a different signature, without
claiming support for one Waybar process managing multiple Hyprland sessions.

- Replaced pass-by-value std::string parameters with const std::string&
or std::string_view to prevent SSO overallocations.
- Refactored static mapping functions in UPower to return
std::string_view instead of constructing std::string literals, enabling
perfect cache locality.
- Optimized string concatenation in hot loops (network IPs, inhibitor
lists, sway window marks) by using std::string::append() and
pre-reserving capacity instead of overloaded operator+ which produces
temporary heap instances.
These optimizations reduce high-frequency memory churn and overall heap
fragmentation within the main rendering loops.

Command tests did not assert behavior when exec fails in child processes.
I added deterministic regression coverage that forces execl/execlp failure and
verifies non-zero exit status propagation for both open() and forkExec paths.

The hyprland IPC fixture was no longer used by the current test setup.
I removed the dead fixture so the test code reflects the actual execution path
and is easier to maintain.

Hyprland tests did not explicitly verify descriptor behavior on key failure
paths.
I added focused tests for missing instance signature and connect-failure paths
that assert file descriptor counts stay stable across repeated attempts.

SafeSignal could queue events forever when worker threads emitted faster than
the main loop could consume, which risks memory growth and stale updates.
I added a queue cap with a drop-oldest policy so growth stays bounded under
burst load, plus a regression test that validates bounded delivery.

SleeperThread concurrency paths needed stress coverage around wake/stop races.
I added a subprocess stress test that repeatedly interleaves wake_up() and
stop() and verifies the worker exits cleanly.

We needed a regression test for reassignment safety after lifecycle fixes.
I added a subprocess test that reassigns SleeperThread workers and verifies the
process exits normally instead of terminating.

If you have reload_style_on_change enabled, and use dynamic appearance
styling (style-dark.css and style-light.css), then changing the
appearance doesn't update the files that are being watched for reload.
Add a method to CssReloadHelper to change the CSS file being watched,
and also provide the CSS file as a parameter to the callback so setupCss
can be called on the right file when the file watcher triggers.
Allows us to disable modules entirely when socket connection isn't
working. This is similar to how sway handles their socket connections
disabling modules. This supports a single waybar config for multiple
IPCs.
- Add tests for global locale.
- Warn about missing locales.
- Downgrade REQUIRE to CHECK.
- Skip tests if localized formatting does not work as expected.
