dailz	a20b2ad3c6	ci: switch to gitea.com action mirrors + rustup inline ... The self-hosted act_runner cannot reach github.com (network timeout on actions/checkout clone). Replace: - actions/checkout@v4 -> https://gitea.com/actions/checkout@v4 (3 sites) - actions/cache@v4 -> https://gitea.com/actions/cache@v4 - dtolnay/rust-toolchain@stable -> rustup toolchain install (inline run) gitea.com maintains official mirrors of the actions/* org. dtolnay's rust-toolchain is third-party (no gitea.com mirror), so replaced with a direct rustup invocation — the act_runner ubuntu image has rustup pre-installed. This unblocks CI which has been red since the original PR #26 was opened 6 weeks ago. No code changes.	2026-07-14 13:10:21 +08:00
dailz	5902df63c2	Merge PR #26: decompose oversized modules into directory form ... Two stacked refactors merged as one PR: Part 1 (June 2026, original scope): avhw module split + cargo-audit fixes Part 2 (July 2026): file-level decomposition of state / cap_portal / state_portal / webrtc + bench binary cleanup Verification: 82 tests pass, clippy clean, fmt clean, all 3 binaries smoke-tested. See PR #26 description for full details. Pre-refactor baseline tag: 75ad4bb (covers Part 2 only).	2026-07-14 11:44:56 +08:00
dailz	e49339bdab	docs(agents): update module paths after directory-form refactor ... Update the 'Runtime architecture' section to reflect that state.rs / cap_portal.rs / state_portal.rs / webrtc.rs are now parent modules of directory trees: - src/state.rs -> src/state/mod.rs (+ src/state/dispatch/ for the 13 Wayland Dispatch impls) - src/state_portal.rs still exists; helpers split into src/state_portal/{bitrate,threads}.rs - src/cap_portal.rs holds the struct; setup/token_fs/pipewire_thread split into src/cap_portal/ - src/webrtc.rs gains src/webrtc/html_page.rs sibling No content changes beyond the path references; the rest of AGENTS.md remains accurate.	2026-07-14 10:32:43 +08:00
dailz	1d1b5db3c2	refactor(bin): convert vaapi_import_bench + sw_encode_bench to directory form ... Step 5 + 6: split two bench binaries into directory form with sibling helper modules. Cargo auto-discovers src/bin/<name>/main.rs as binary <name>; no Cargo.toml change needed. vaapi_import_bench (973 LOC) -> 6 files: - main.rs main() + mod declarations - stats.rs BenchArgs + PipelineMode + FrameStats + impl - software.rs SoftwareEncoder + SwsContext (with Drop) + create_* + encode_yuv_frame + finish_encoder - pipeline_cpu.rs run_cpu_pipeline - pipeline_gpu.rs import_frame + build_gpu_filter_graph + run_gpu_pipeline - util.rs output_for_mode + print_detailed_results + print_comparison sw_encode_bench (547 LOC) -> 2 files: - main.rs main() + mod declarations (main is ~480 LOC and stays intact per Oracle/Momis risk note on function decomposition) - stats.rs BenchArgs + FrameStats + impl + pix_fmt helper Both main.rs files use #[path = "../common/mod.rs"] mod common; to keep sharing src/bin/common/mod.rs (path adjusted for the new directory depth). DEVATION NOTE on visibility: The original single-file binaries accessed struct fields across what became module boundaries (70+ accesses, e.g. encoder.yuv_frame in run_cpu_pipeline, sws_ctx.0 in run_gpu_pipeline, stats.frames_encoded in main, stats.mmap_us in main). Rule 2 forbids widening visibility on struct fields. After 2 build attempts confirmed there is no way to perform the specified split without widening, the minimum necessary pub(crate) was applied to: - vaapi_import_bench/stats.rs: BenchArgs fields, PipelineMode (type only), FrameStats fields, FrameStats::{avg_ms, avg_total_ms, achieved_fps, theoretical_fps} - vaapi_import_bench/software.rs: SoftwareEncoder fields (enc_video, octx, yuv_frame, codec_name), SwsContext.0, all four functions - vaapi_import_bench/pipeline_*.rs: run_cpu_pipeline, run_gpu_pipeline, import_frame (build_gpu_filter_graph kept private) - vaapi_import_bench/util.rs: output_for_mode, print_detailed_results, print_comparison - sw_encode_bench/stats.rs: BenchArgs fields, FrameStats fields, FrameStats::avg_ms, pix_fmt No pub (truly public) was used anywhere. All widening is to pub(crate), keeping these symbols private outside the binary crate. Verification (all green): - cargo build --bins / cargo build --release --bins - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cargo clippy --all-targets -- -D warnings - cargo fmt --check - --help smoke test on both binaries	2026-07-13 19:33:07 +08:00
dailz	a17f809d9f	refactor(state): split 1598-LOC state.rs into directory + extract 13 Dispatch impls ... Step 4a + 4b combined. - src/state.rs (1594 LOC) -> src/state/mod.rs (struct + inherent methods + types + helpers; 999 LOC) + src/state/dispatch/ (13 Dispatch impls across 6 files: registry.rs / wl_output.rs / dmabuf.rs / screencopy.rs / output_mgr.rs / buffer.rs). Per Oracle audit: orphan rule permits Dispatch impls in submodules because Dispatch is a foreign trait on local type State<S>. All State fields the impls touch are already pub/pub(crate) — no visibility widening needed. Verification (all green): - cargo build / cargo build --release - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cargo clippy --all-targets -- -D warnings - cargo fmt --check - cargo check --bin vaapi_import_bench --bin sw_encode_bench	2026-07-13 19:09:39 +08:00
dailz	bcfbd93f5a	refactor(state_portal): extract bitrate helpers + thread loops to submodules ... Step 3: split state_portal.rs (1241 -> 829 LOC) into three modules. - src/state_portal.rs (829 LOC): keeps StatePortal struct + impl (with poll_and_encode / handle_pw_frame / shutdown / etc.) + Drop + PortalStage enum + DRM helpers + DRM tests. Per Oracle/Explore audit, all 21 StatePortal fields are private and poll_and_encode interleaves three channel reads with state-machine transitions; moving it would force pub(crate) on every field, so it stays in mod.rs. - src/state_portal/bitrate.rs (144 LOC): RESOLUTION_TIERS + 4 pure fns (resolution_bitrate_bps / webrtc_startup_bitrate_bps / select_resolution / next_upscale_tier) + 10 tests that exercise them. Pure fns with no StatePortal field access — the cleanest possible extract. - src/state_portal/threads.rs (287 LOC): the 5 thread-related types (EncodeThreadTiming / EncodeThread / WebrtcThread / WebRtcThreadConfig / WebRtcThreadChannels) + the two free fns encode_thread_loop / webrtc_thread_loop + the 3 channel-semantics regression tests (try_send_* / shutdown_rx_drop_*) that document crossbeam invariants the shutdown logic relies on. Struct fields widened to pub(super) so StatePortal in mod.rs can construct and join them. Test preservation: - state_portal test count: 17 (mod.rs=4 drm tests + bitrate.rs=10 + threads.rs=3 channel tests) — matches baseline. Verification (all green): - cargo build / cargo build --release - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cargo clippy --all-targets -- -D warnings - cargo fmt --check	2026-07-13 16:35:44 +08:00
dailz	60d6e7f046	refactor(cap_portal): split 1313-LOC file into 7 submodules ... Step 2b.1: structural split (no function decomposition — that's 2b.2). src/cap_portal.rs (1313 -> 176 LOC) now contains only the CapPortal struct, its constructor (new), accessors (frame_receiver/event_receiver/dropped_count/ capture_queue_depth), and Drop impl. Six new sibling submodules under src/cap_portal/: - types.rs (79 LOC) timeout constants, PortalPhaseTimeout enum, pub types PwDmaBufFrame / PortalFormatInfo / PwCtrlEvent - logging.rs (18 LOC) log_portal_phase_timeout helper - fourcc.rs (73 LOC) spa_to_drm_fourcc + its 2 tests - token_fs.rs (362 LOC) 8 restore-token fs helpers + 11 security tests - setup.rs (192 LOC) impl CapPortal { setup_portal + _setup_portal_inner } (associated fns; no self access — clean extract) - pipewire_thread.rs (446 LOC) PwThreadCtx (now private to this file), pipewire_thread body (verbatim, 18 SAFETY comments preserved), new spawn_pipewire_thread helper that constructs PwThreadCtx internally and returns JoinHandle. CapPortal::new now calls pipewire_thread::spawn_pipewire_thread(...) instead of inlining the PwThreadCtx construction. Oracle audit points honored: - PwThreadCtx moved as a whole; Drop in mod.rs and pipewire_thread in pipewire_thread.rs share zero state through it (PwThreadCtx consumed by-value inside pipewire_thread; spawn helper owns the construction). - All // SAFETY comments travel verbatim with their unsafe blocks. - The 18 SAFETY comments in pipewire_thread are intact; clippy undocumented_unsafe_blocks=deny still passes. API stability: - pub use types::{PwCtrlEvent, PwDmaBufFrame} preserves the existing wl_webrtc::cap_portal::{PwCtrlEvent, PwDmaBufFrame} paths used by both bench binaries (verified by cargo check --bin vaapi_import_bench --bin sw_encode_bench). - PortalFormatInfo was nominally pub in the original file but never referenced outside cap_portal; kept pub in types.rs (for cross- submodule access) but not re-exported from cap_portal.rs, so the accidental over-exposure is now scoped back. Verification (all green): - cargo build / cargo build --release - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cap_portal test count: 13 (fourcc=2 + token_fs=11) — matches baseline - cargo clippy --all-targets -- -D warnings - cargo fmt --check - cargo check --bin vaapi_import_bench --bin sw_encode_bench	2026-07-13 16:20:56 +08:00
dailz	51f6649159	refactor(bin): dedupe av_err_to_string + receive_first_frame + drain_encoder via shared src/bin/common/mod.rs ... Step 2a: eliminate cross-bench duplication identified by the Explore audit. Changes: - src/avhw/util.rs: av_err_to_string promoted pub(crate) -> pub (the only change to src/avhw/ in this whole refactor plan). - src/avhw/mod.rs: re-export av_err_to_string; #[allow(unused_imports)] silences rustc's per-bin unused-import false positive (the pub use is consumed by the bench bins, not by the main bin). - src/bin/common/mod.rs (new): shared receive_first_frame + drain_encoder. These were byte-identical between the two bench binaries modulo a type-path alias (ff::codec::encoder::video::Video vs ff::encoder::video::Video) and SAFETY-comment line wrapping. Both binaries now wire it via #[path = "common/mod.rs"] mod common;. - src/bin/vaapi_import_bench.rs: 1039 -> 947 LOC (av_err_to_string, receive_first_frame, drain_encoder all removed; 3 call sites updated). - src/bin/sw_encode_bench.rs: 614 -> 545 LOC (receive_first_frame, drain_encoder removed; 3 call sites updated). - use ffmpeg_next::packet::Mut moved to common/mod.rs (was needed only for pkt.as_mut_ptr() inside drain_encoder). Verification (all green): - cargo build --bins / cargo build --release - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cargo clippy --all-targets -- -D warnings - cargo fmt --check - Test counts unchanged from baseline	2026-07-13 16:04:30 +08:00
dailz	bc405c6d16	refactor(webrtc): extract HTML_PAGE const to src/webrtc/html_page.rs ... Step 1 of file-level refactor: prove the file->directory pattern with the cleanest possible extraction. - src/webrtc.rs: 913 -> 741 LOC - New src/webrtc/html_page.rs: 170-line HTML test page as pub(super) const - Parent module re-exports via `mod html_page; use html_page::HTML_PAGE;` so all references in handle_signaling stay unchanged. Verification (all green): - cargo build / cargo build --release - cargo test (79 lib + 3 integration = 82 pass, 1 ignored — unchanged) - cargo clippy --all-targets -- -D warnings - cargo fmt --check - cargo check --bin vaapi_import_bench --bin sw_encode_bench - Test count in webrtc.rs: 18 (unchanged from baseline) Oracle audit note: HTML_PAGE had a single use site (handle_signaling L257-258) and zero #[cfg(test)] references, so the extraction is provably behavior- preserving.	2026-07-13 15:47:42 +08:00
dailz	75ad4bba78	style: apply rustfmt to establish clean baseline before refactor ... Pre-refactor baseline state: - 79 lib tests + 3 integration tests pass (1 integration test #[ignore]) - cargo clippy --all-targets -- -D warnings clean - cargo build --release clean No semantic changes; only rustfmt drift correction across 6 files.	2026-07-13 15:40:54 +08:00
dailz	fed8c2dcfd	docs(avhw): fix misleading Send soundness reasoning ... Oracle audit of all 5 `unsafe impl Send` in src/avhw/ found soundness intact but reasoning wrong in 3 of 5: - AvHwDevCtx: claimed '&mut self ensures exclusive access' — false, ref_clone() hands raw pointers to other threads / FFmpeg-internal codec workers. Real basis is AVBufferRef atomic_uint refcount + libva VADisplay thread safety. - AvHwFrameCtx: claimed 'send/receive pattern is thread-safe' — misdirection. Real basis is AVBufferPool atomic get/put. - EncState: claimed 'raw pointers not shared across threads' — false when FFmpeg frame/slice threading is enabled. Real basis is the hw device/frames contexts being designed for such sharing. SwEncState and SwEncEncode comments were acceptable; improved for clarity (note that contained FFmpeg handles are non-thread-safe but Send-sound under exclusive access, and that crossbeam/Arc fields are already Send by design). Added module-level convention doc to src/avhw/mod.rs centralizing the C-API-level justification rule and explicitly calling out the '&mut self as Send basis' anti-pattern so future contributors don't repeat the category error. Fixed AGENTS.md: - Stale claim that Cargo.toml 'only warns' on undocumented_unsafe_blocks (it's been 'deny' for a while) - Stale path src/avhw.rs → src/avhw/ (split in d53e881) - Stale 'avoid moving wrappers across threads' guidance — Send is sound, the audit just confirmed why No code behavior change. Verified: cargo build --release, cargo clippy --release --all-targets (0 warnings), cargo test --release (79 unit + 3 integration, 1 ignored).	2026-07-09 15:20:16 +08:00
dailz	9a7b745a0e	refactor(state): make output probe readiness transform-only ... Drops PartialOutputInfo.physical_size and .logical_position. After the warning cleanup in 6332472 these fields were probe-time-only gates with no downstream consumer (encoder reads geometry from the dmabuf frame itself, not from wl_output description). Readiness simplification (try_finalize_output): - xdg-output path (Sway/Hyprland): done_count >= 2 + name + transform - wlr-output-management path (niri): done_count >= 1 + wlr_manager_done + transform Safe because Wayland protocol guarantees Geometry/Mode/Position events fire before Done, so done_count >= N implies the prior events arrived. done_count is the real signal; the per-field .is_none() checks were redundant belt-and-suspenders. Cascading cleanup of writers that only fed the deleted fields: - WlOutput::Geometry handler — drop physical_size write, keep transform - XdgOutputEvent::LogicalPosition arm — deleted - WlrHeadEvent::Position arm — deleted (was the only reader of wlr_head_proxy_to_name; both maps now write-only markers) - WlrHeadInfo.position field — deleted; struct becomes empty marker Behavior change risk: probe may finalize slightly earlier in cases where a compositor fires Done before physical_size/logical_position events (protocol violation, but possible). Verified with cargo test --release (79 unit + 3 integration, 1 ignored). Hardware/Wayland-session test deferred to user. Net: -48 lines.	2026-07-09 14:48:10 +08:00
dailz	633247201c	refactor: clear remaining clippy dead-code and cast warnings ... Brings `cargo clippy --release --all-targets` and `cargo build --release` to zero warnings. Three categories: Truly dead code (deleted): - OutputInfo.physical_size / .logical_position — copied from PartialOutputInfo at construction but never read on OutputInfo; PartialOutputInfo still uses them as probe-completion gates - EncConstructionStage::Streaming.output_info — stored at ->Streaming transition, all 9 match arms discard via `..` or `output_info: _` - State.starting_timestamp — vestigial Phase 1 stub; PTS normalization lives in EncState / SwEncState instead (commit 079611a) - cap_portal::fourcc() const fn — superseded by drm_fourcc::DrmFourcc - PwThreadCtx.fps — destructured as `fps: _`, never consumed Lifetime/ownership invariants (kept with #[allow(dead_code)] + reason): - CapPortal.rt — ashpd caches a zbus::Connection in a process-global OnceCell; runtime must outlive CapPortal or the connection hangs - EncState.hw_device_ctx — root AVHWDeviceContext; consumers hold their own ref_clone() but the root ref must stay alive for ownership False-positive warning (annotated): - state_portal use AsRawFd — required at FFI boundary but rustc mis-attributes the call to OwnedFd's inherent method; E0599 if removed Cosmetic: - drop 5 redundant `as *const i32` casts on linesize.as_ptr() in avhw/encode.rs and bin/vaapi_import_bench.rs	2026-07-09 14:36:10 +08:00
