refactor(rog-dbus): centralize shared D-Bus connections and typed proxy helpers - #339
Conversation
…leak (OpenGamingCollective#229) rog-control-center opened a new zbus::Connection::system() on every find_iface_async query in periodic 2-second polling loops, causing file descriptors (eventfd and unix domain sockets) to accumulate until hitting the EMFILE limit and crashing with a panic after ~12 minutes. Centralize process-wide D-Bus system connections in rog-dbus using OnceCell for async and OnceLock for blocking calls, and update rog-control-center to reuse the shared connections and proxy lookup helpers across all UI setup modules.
Re-export all D-Bus proxy types at the root of rog-dbus and provide typed proxy factories (platform_proxy, fan_curves_proxy, backlight_proxy) and device discovery helpers (find_armoury_proxies, find_aura_proxies, find_slash_proxies, find_anime_proxies, find_xgm_led_proxies, find_scsi_aura_proxies) with sync and async variants. Modernize internal find_iface implementations with guard clause error returns and idiomatic iterator filtering.
…ury proxy helpers Refactor asus-shutdown to reuse the process-wide shared D-Bus connection from rog_dbus instead of creating multiple Connection::system() instances. Replace raw ObjectManagerProxy introspection and manual AsusArmoury proxy instantiation with rog_dbus::find_armoury_proxies(), and modernize is_card_entry using str::strip_prefix.
…s and discovery helpers Migrate all UI setup modules (setup_fans, setup_system, setup_gpu, setup_aura, setup_slash, setup_anime) to use high-level typed proxy factories and device discoverers from rog_dbus instead of manual proxy builders. Remove redundant proxy re-exports from zbus_proxies, and modernize control loops using let-chains and iterator combinators.
…very helpers Update asusctl CLI handlers across main.rs, slash_cli.rs, and xgm_led_cli.rs to use high-level typed proxy factories (e.g. platform_proxy_blocking, backlight_proxy_blocking, fan_curves_proxy_blocking) and discoverers from rog_dbus. Remove manual Connection::system() calls and raw find_iface_blocking invocations from CLI handlers.

failure branch to refer to Anime interfaces instead of aura interfaces; leave
the control flow unchanged.
In `@rog-control-center/src/ui/setup_system.rs`:

- Around line 705-712: Update the attribute setup around attr.name() and
attr.current_value() so setup is gated only on successful name retrieval; log
name-read failures instead of silently discarding them. Move current_value()
reads into only the value-consuming match arms (BootSound, ScreenAutoBrightness,

- Around line 318-348: Make the D-Bus singleton tests explicit

- Around line 112-118: Update the interface-discovery logic around the
paths-empty check to treat missing devices as a normal result rather than a
propagated failure: return an empty Vec, or introduce a typed NoDevice error and
handle it separately from D-Bus errors. Preserve actual D-Bus failure
propagation and the existing multiple-interface warning.

Include the property name in these error messages.
init_minmax_property! right above already logs stringify!($property). This macro does not. A box with eight PPT attributes therefore emits eight identical "Failed to get min value on profile change" lines, and you get to guess which attribute is broken. That is not logging, that is noise generation. You are already touching these lines; add the name.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Do not gate the whole attribute setup on current_value(), and stop swallowing both errors.
This condition now requires both current_value() and name() to succeed before anything happens for an attribute. Look at what is actually inside the match: every PPT and NV arm (PptPl1Spl through DgpuTgp) uses init_minmax_property!, which re-reads min, max, and current from the proxy itself. Those arms never touch the outer value. Only BootSound, ScreenAutoBrightness, McuPowersave, PanelOverdrive, and MiniLedMode use it.
So a single failing current_value() read now throws away the callbacks, the external-change watcher, and the min/max wiring for an attribute that did not need the value in the first place. And asusd really does return an error here: AsusArmoury::current_value returns fdo::Error::Failed("Could not read current value") when the sysfs read fails or the value is not an integer. The user gets a dead PPT slider stuck at the MINMAX default of min 0, max 0, current -1.0, for the rest of the session, with no retry.
Worse, both errors are now discarded. The previous code at least logged when the name could not be read. Now the attribute vanishes without a single line in the log. Debugging that is a treat.
Gate on name() only, and read the value where it is needed.

+ };
+ debug!("Setting up {} = {value}", <&str>::from(name));Keep the rest of the match as it is. If you prefer not to substitute a default for value, then split the match so the five value-consuming arms bail out on their own and the minmax arms proceed regardless.

🩺 Stability & Availability | 🔵 Trivial | 💤 Low value
The doc comment admits a race, and then you ship the race anyway.
The logic is correct, but it is sloppy. On a cold cache two threads can each open a system bus connection, and one gets thrown away. You do not need get_or_try_init for this. Do the fallible work only when you have won the initialization, using Once or a small mutex, or return the error without creating a throwaway connection.
♻️ One way to avoid the throwaway connection
-/// Note: The initial `get()` plus `get_or_init()` may briefly create two connections
-/// under a race condition, with the losing connection dropped intentionally because
-/// `OnceLock::get_or_try_init` is unavailable.
+/// The connection is created at most once. Failed attempts are not cached, so a
+/// later call retries.

Preserve “no device” as a normal result
Several asusctl callers propagate this error with ?, so systems without Slash, XG Mobile LED, AniMe, SCSI Aura, or Armoury interfaces report command failures. asus-shutdown also reports the absence as a failed queue query. Return an empty Vec for absent devices, or add a typed NoDevice error and handle it separately from D-Bus failures.

These "tests" pass on a machine with no D-Bus, which means they test nothing in CI.
Both singleton tests print a message and return Ok when the system bus is missing. A green test run then proves nothing about the caching behaviour. That is worse than no test, because it looks like coverage. Gate them behind an ignored attribute or a feature so the skip is explicit and visible.

Description
This PR is based on #338 as a follow-up enhancement. Over time, D-Bus/zbus connection logic and proxy instantiation became duplicated and spread across various workspace crates (
asusctl,rog-control-center,asus-shutdown), rather than leveragingrog-dbusas the single source of truth.Why this is needed:
Beyond code duplication, creating uncoordinated D-Bus connections across modules introduced several runtime risks and issues:
Connection::system()in polling loops accumulated Unix domain sockets andeventfdhandles until exhausting OS file descriptor limits (EMFILE).zbusproxy instances did not share property caches or signal invalidations, risking stale reads across concurrent UI/CLI tasks./.../10preceded/.../2) could result in different components selecting different devices as primary.dbus-daemon.Summary of Changes:
rog-dbus:system_connectionviatokio::sync::OnceCell) and blocking (system_connection_blockingviastd::sync::OnceLock) system connections.platform_proxy,fan_curves_proxy,backlight_proxy) and device discovery helpers (find_armoury_proxies,find_aura_proxies,find_slash_proxies,find_anime_proxies,find_xgm_led_proxies,find_scsi_aura_proxies).cmp_object_pathsto ensure numerical ordering for trailing object path segments with byte-order fallback.rog-control-center: Migrated UI setup modules (setup_fans,setup_system,setup_gpu,setup_aura,setup_slash,setup_anime) to use the centralized helpers and shared connection.asusctl&asus-shutdown: Updated CLI handlers and shutdown cleanup to use centralized blocking proxy factories.Tested Hardware & Environment
