fix: address codex review findings on probe/watchdog fallback

- a probe or raster-stall failure record now also downgrades sessions that are already running: main_set_local_option broadcasts the fallback for failed-* health writes, which also closes the hole where the watchdog's idempotence guard no-oped after the probe had already written the record - probe success requires a frame timing newer than the first push: 'consumed' advances inside the plugin callback before the GL/Metal upload, so a raster thread hanging in the driver no longer counts as a pass (and cannot clear a previous failure) - watchdog failures are tagged with the failing backend (failed-watchdog-rgba/gpu); the rgba-only probe clears only the rgba class, so a working pixel-buffer path can no longer re-enable a broken D3D shared-handle path every launch - the watchdog pauses while the session's window is hidden (new session_set_render_visible FFI wired to the window minimize/restore events): a display registered in a minimized window no longer records a false global failure; observation now counts pushes within the window rather than since registration - probe failure verdicts additionally require a resumed lifecycle, matching the raster-stall monitor - linux plugin: deferred-unref grace lengthened to 10s (no raster-side completion barrier exists; documented as heuristic), ref bumped Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
keep lockfile at repo resolution, only bump the two plugin refs

 ### Comments

-* Avoid comments unless they explain a non-obvious reason, constraint, or workaround.
-* Never restate what the code does; prefer clearer code instead.
-* If the code is self-explanatory, add no comment.
+* Keep them short: one line by default, three at most.
+* Say **why**, never what. If the code already says it, delete the comment.
+* A comment must never be longer than the code it describes.
+* Applies to YAML, shell and Python too, not just Rust.

 ### Be minimally invasive

 * Prefer purely additive changes: layer new (`#[cfg]`-gated) blocks or new functions around existing code instead of restructuring it. The ideal diff for a fix adds lines and modifies/deletes none.
 * Do not extract or reshape existing code just to enable your new code; look for a mechanism that leaves existing lines untouched (e.g. hide/show an existing object instead of refactoring its construction into a helper for rebuilding).
-* Accept a little duplication over a restructure. A new function that repeats a few lines of an existing one is a better diff than reshaping the original so both can share it.
 * Put new logic in self-contained functions in the module it belongs to (platform-specific logic in `src/platform/`, with `use` inside the function body to avoid churning shared import blocks). Call sites in shared files (`src/tray.rs`, `src/core_main.rs`, `src/server/connection.rs`, …) should be thin one-line hooks.

-### Scope check before touching shared code
-
-* Before changing a shared trait, a shared struct, or the signature of a widely used function, check whether the bug or feature is specific to one path. If it is, keep the change inside that path unless that is impossible, and say in the PR why it was.
-* If an unrelated caller needs `Default::default()`, `None`, or another placeholder solely to satisfy a signature you changed, the diff is too broad: stop and redesign.
-* The expected shape of a fix is a new function in the feature's own module, plus at most a new field or a thin hook in the shared code it needs. Feature-specific state belongs beside the feature's existing state, not in a new abstraction every caller has to learn.
-
-### Mandatory regression-surface check
-
-Before considering any implementation complete, perform a minimization pass over the final diff.
-
-* Inspect every modified existing file and every modified existing code path. Each must be strictly necessary for the requested change. Revert changes that are merely cleanup, refactoring, consistency improvements, or fixes for pre-existing issues.
-* For new features, preserve the existing implementation path when the feature is disabled or unsupported whenever practical. `feature off` should run the old code, not a rewritten equivalent.
-* Do not route existing behavior through a new abstraction merely to share code with the new feature. Prefer a parallel new function or a small amount of duplication over changing a proven existing path.
-* Keep new implementation logic in new or feature-specific modules. Changes to shared/core files should normally be thin hooks, capability checks, or protocol plumbing.
-* Do not fix unrelated pre-existing bugs in the same PR. Put them in a separate change unless they directly block correctness or security of the requested work.
-* For submodule bumps, inspect the exact commit range and ensure unrelated changes are not being pulled into the parent PR.
-* Before finalizing, explicitly report the regression surface: list the existing files and existing runtime paths whose behavior changed, and explain why each change is unavoidable.
-* During review, treat an unnecessarily modified legacy path as a review finding even if tests pass and the rewritten behavior appears equivalent.
-
-## Reviewing a PR
-
-* Review only what the diff introduces. Verify ownership with `gh pr diff` before reporting a finding — if the offending lines are untouched context, it is a pre-existing problem, not this PR's.
-* List pre-existing problems in a separate section at the end, or leave out the ones that are not fatal. Never mix them into the findings the author has to fix.
-* Before re-reviewing, read the author's reply comments. Do not re-raise items they declined on scope grounds.
-* State a finding's consequence exactly: distinguish "the value is lost" from "the shortcut is inert but the value still saves".

rustdesk	24a16d9a30	fix: address codex review findings on probe/watchdog fallback - a probe or raster-stall failure record now also downgrades sessions that are already running: main_set_local_option broadcasts the fallback for failed-* health writes, which also closes the hole where the watchdog's idempotence guard no-oped after the probe had already written the record - probe success requires a frame timing newer than the first push: 'consumed' advances inside the plugin callback before the GL/Metal upload, so a raster thread hanging in the driver no longer counts as a pass (and cannot clear a previous failure) - watchdog failures are tagged with the failing backend (failed-watchdog-rgba/gpu); the rgba-only probe clears only the rgba class, so a working pixel-buffer path can no longer re-enable a broken D3D shared-handle path every launch - the watchdog pauses while the session's window is hidden (new session_set_render_visible FFI wired to the window minimize/restore events): a display registered in a minimized window no longer records a false global failure; observation now counts pushes within the window rather than since registration - probe failure verdicts additionally require a resumed lifecycle, matching the raster-stall monitor - linux plugin: deferred-unref grace lengthened to 10s (no raster-side completion barrier exists; documented as heuristic), ref bumped Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 12:30:15 +08:00
rustdesk	8fc82d04ac	keep lockfile at repo resolution, only bump the two plugin refs Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 11:48:28 +08:00
rustdesk	c6c001a15e	bump texture plugins with adversarial-review fixes flutter_texture_rgba_renderer 7932bf9: linux double-free/terminate-UAF fixes, exported GetConsumed (was invisible to dlsym under hidden visibility - the watchdog was silently disabled on Linux), C++14 shared_timed_mutex; macos autoreleasepool + failed-registration guard. flutter_gpu_texture_renderer 208619e: rendering_ no longer sticks true before the first populate; honest GetConsumed semantics (descriptor fetches; EGL bind failure still advances it) - noted at the gpu watchdog call site. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 11:47:54 +08:00
rustdesk	7da2bbe6ac	fix: address texture watchdog/probe review findings - watchdog: compare the plugin's cumulative consumed counter against a snapshot taken when arming (re-arm was a no-op before), and judge on cumulative pushes + elapsed time so sparse damage-driven streams are still detected - failure handling is idempotent (one record per breakage) and updates every render session like main_set_local_option does, not only the failing one; the fallback toast is not claimed for multi-display windows the soft path cannot rescue - probe: skip when the consumed API is missing (old plugin) or a raster-stall is recorded (compositing could hang the main window); a fail verdict requires fresh frame timings and a non-minimized window; a pass never clears failed-raster-stall; toast only when texture rendering was effectively on; probe pixel is transparent - raster-stall monitor: judge on frame-timing staleness (a mid-episode hang was undetectable before), gate on lifecycle/minimized/idle with a moving quiet anchor, threshold 30s, shared with the camera page; clear stateGlobal minimized flag on plain window restore - adopt mismatched frame sizes only in multi-ui-session mode (legacy mode pairs frames loosely and could ping-pong between displays) - drop the now-dead closeSession parameter from texture destroy(); trim comments to repo style Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 11:22:13 +08:00
rustdesk	c5adac828b	bump hbb_common to merged main (texture-render-health key) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 09:58:31 +08:00
rustdesk	7c23e1f4b9	fix: texture render lifetime protocol, watchdog fallback, startup probe Root cause of #15848 (and the long-standing macOS #6296 / Linux #3343 class): raw native texture pointers are shared across the platform thread, the engine raster thread and the video thread, with teardown ordered by a 100 ms sleep - or, when moving a tab to a new window, by nothing at all. A lost race frees the texture while it is still in use: the raster thread parks on a destroyed lock (frozen/black view, a never-presented 'transparent' hole, every later session black) and the video thread hangs while holding session locks (app half-dead until restart, still reported as Responding). - unregister textures with compare-and-clear (new session_unregister_* FFI): a late clear can no longer wipe a new window's registration (#8016) and Rust never keeps pushing into a freed texture; the 100 ms sleeps are gone (the plugins now drain in-flight pushes and defer object deletion until the raster thread is done) - guard the async texture create path against destroy racing it (#13596) - per-display locks: the per-frame plugin call no longer holds session-level locks, so a stalled plugin or driver call cannot freeze every window's UI thread - adopt the frame size after 30 consecutive mismatches instead of dropping frames forever (silent black screen on a live connection) - watchdog: frames pushed but never consumed by the engine fall the session back to software rendering live, record texture-render-health, and flip the effective default off; toggling the option clears the record and re-arms validation - Dart raster-stall monitor records a hung raster thread for the next launch (rendering cannot be rescued in-process in that state) - startup probe: render one frame through a 1x1 texture in the main window each launch; failure disables texture rendering before the first session goes black, a pass self-heals a stale failure record Platform defaults are unchanged (macOS off, Win10+ on, Linux on). Requires flutter_texture_rgba_renderer ad4c37e and flutter_gpu_texture_renderer 767bb9f (pinned in pubspec). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-13 09:54:17 +08:00
