The FFmpeg decoder then reads them through a scripted demuxer and the AVAssetReader decoder through a scripted reader that starts at the CMTime the real code computes. Without the feature the product build only gains a single-variant enum around the native reader. --- crates/rendering/Cargo.toml | 1 + crates/rendering/src/decoder/avassetreader.rs | 4 + crates/video-decode/Cargo.toml | 4 + crates/video-decode/src/avassetreader.rs | 95 +++- crates/video-decode/src/ffmpeg.rs | 29 ++ crates/video-decode/src/lib.rs | 2 + crates/video-decode/src/scripted.rs | 413 ++++++++++++++++++ 7 files changed, 530 insertions(+), 18 deletions(-) create mode 100644 crates/video-decode/src/scripted.rs diff --git a/crates/rendering/Cargo.toml b/crates/rendering/Cargo.toml index cce5010de20..c54023e8c8c 100644 --- a/crates/rendering/Cargo.toml +++ b/crates/rendering/Cargo.toml @@ -70,6 +70,7 @@ windows_0_58 = { package = "windows", version = "0.58", features = [ [dev-dependencies] cap-media-info = { path = "../media-info" } +cap-video-decode = { path = "../video-decode", features = ["scripted"] } tempfile = "3" pollster = "0.4.0" pretty_assertions = "1.4.1" diff --git a/crates/rendering/src/decoder/avassetreader.rs b/crates/rendering/src/decoder/avassetreader.rs index af79c9560e2..d9ab926e6c8 100644 --- a/crates/rendering/src/decoder/avassetreader.rs +++ b/crates/rendering/src/decoder/avassetreader.rs @@ -639,6 +639,10 @@ impl AVAssetReaderDecoder { sequential_access: Arc, ) { let dimensions = (|| { + #[cfg(test)] + if let Some(dimensions) = cap_video_decode::scripted::dimensions(&path) { + return Ok(dimensions);

Model-based tests of the decoder request logic. +//! +//! The real decoders (AVAssetReader pool on macOS, FFmpeg everywhere) are +//! spawned through `spawn_decoder` on scripted media +//! (`cap_video_decode::scripted`): sample lists with exact presentation times +//! and sync flags. Seeded request sequences (export and playback order, double +//! requests at 60 fps over 30 fps grids, timelines with cuts, speed changes +//! and backward jumps, transitions, random seeks, keyframe seeks, scrubs, +//! jumps back into old pts holes, reads past the end) run against them, and +//! every answer is checked against the reference rule below. +//! +//! Reference rule (the decoder contract documented next to `pts_to_frame`): +//! a sample is labelled `round(fps * pts_seconds)` on the decoder grid, where +//! FFmpeg measures pts from the stream start time and AVAssetReader from +//! zero. A request for time `t` asks for grid index `floor(t * fps)`. The +//! correct answer is the newest sample whose label is at or before that index +//! (the frame on screen at `t`); when several samples share that label any of +//! them is accepted. A request before the first sample is answered with the +//! first sample. +//! +//! An answer that is not the grid frame but is the sample on screen at the +//! exact request time is `grid-rounding`: correct for a seek straight to `t`, +//! but different from what sequential playback shows for the same request. +//! Other wrong answers are `future` or `stale` and end the sequence. Every +//! request also checks that the reader did not decode past the sample after +//! the answer (`overread`: the reader running ahead of the requests) and that +//! reader starts and seeks stay within a budget of two per jump in the request +//! stream (`resets`); these, like `grid-rounding`, are recorded once and the +//! sequence continues. A request that gets no frame is `dropped`, and the +//! macOS AVAssetReader decoder falling back to FFmpeg is `fallback`. +//! +//! Known failures are strict expected failures, per seed, in +//! `expectations.toml`. +//! +//! Environment: +//! - `CAP_DECODER_MODEL_SCALE`: multiplies every family's seed count. +//! - `CAP_DECODER_MODEL_FILTER`: only run cases whose name contains this. +//! - `CAP_DECODER_MODEL_CASE` + `CAP_DECODER_MODEL_SEED_INDEX`: replay one +//! sequence and print every request. +//! - `CAP_DECODER_MODEL_SHRINK`: `none`, `new` (default, unexpected failures +//! only) or `all`. +//! - `CAP_DECODER_MODEL_THREADS`: worker threads (at most 3 for +//! AVAssetReader, 4 for FFmpeg). +//! - `CAP_DECODER_MODEL_REPORT=`: also write the report to +//! `..txt`; `CAP_DECODER_MODEL_SEEDS_OUT=` writes +//! every seed's outcome to `..tsv`. +//! - `CAP_DECODER_MODEL_BLESS=`: write the expectations that match +//! this run to `..toml`. +//! +//! Wall-clock inputs of the decoders (the AVAssetReader idle timeout of +//! 250 ms and the scrub detector's 100 ms cooldown) only matter when a +//! request is delayed by that long, so outcomes are deterministic unless the +//! machine stalls the test threads. + +mod expectations;

The mock injects scripted faults per request (status codes, resets mid-body, network outages, slow and hung responses, cancel/quit trips) and checks the protocol: part order, etags, Content-MD5, auth, and the segment manifest behind each verification receipt. Every case asserts byte-identical stored objects, monotonic progress and the final state or error, and holds requests, media PUTs, manifest PUTs, re-uploaded bytes and orphaned multipart uploads to budgets equal to main's behaviour. Retry backoff, outages and the 5 minute request timeout and retry window cost virtual time only: the 23 cases take about 1 s of wall time. The only non-test change times the Instant progress-manifest interval with tokio::time::Instant, which is std::time::Instant outside tests. --- apps/desktop-gpui/Cargo.toml | 2 +- apps/desktop-gpui/src/store.rs | 5 + apps/desktop-gpui/src/upload.rs | 6 +- apps/desktop-gpui/src/upload/queue.rs | 3 + .../src/upload/queue/verify_resume_tests.rs | 209 ++ apps/desktop-gpui/src/upload/verify_tests.rs | 1776 +++++++++++++++++ 6 files changed, 1998 insertions(+), 3 deletions(-) create mode 100644 apps/desktop-gpui/src/upload/queue/verify_resume_tests.rs create mode 100644 apps/desktop-gpui/src/upload/verify_tests.rs diff --git a/apps/desktop-gpui/Cargo.toml b/apps/desktop-gpui/Cargo.toml index c803d72db27..d67ad17c899 100644 --- a/apps/desktop-gpui/Cargo.toml +++ b/apps/desktop-gpui/Cargo.toml @@ -169,7 +169,7 @@ tauri-winres = "0.3.5" # decoders, renderer and preview tasks are all tokio-spawned -- a current-thread # runtime would deadlock the moment the test thread blocks on a frame.

When none of a source's markers can be identified, sync was silently skipped, so the sync xfail of export/instant/output/mp4/native read as an unexpected pass on macOS while the audio failure hid the measurement. Cases can now record a class as not measured. The shared judge never reports an unmeasured class as fixed, bless leaves its entries alone, and the record, summary and job summary say which class was not measured and why. The failure that prevented the measurement is still judged strictly, and a case that marks a class unmeasured without any failure fails as a harness error. The Instant oracle also lists every located chirp with its decoded index when markers mismatch, skips frames without an emit time instead of timing them against NaN, and notes how late the test emitter handed frames to the pipeline (recorded in verify-emitted.json), to separate a starved test runtime from late processing. --- crates/rendering/src/decoder/model/mod.rs | 1 + crates/verify-expect/src/lib.rs | 81 ++++++++++++++++++++- crates/verify-expect/src/main.rs | 17 ++++- crates/verify/README.md | 5 ++ crates/verify/src/pipeline.rs | 9 ++- crates/verify/src/report.rs | 52 ++++++++++++-- crates/verify/tests/export.rs | 86 +++++++++++++++++++---- scripts/verify/summary.py | 6 ++ 8 files changed, 237 insertions(+), 20 deletions(-) diff --git a/crates/rendering/src/decoder/model/mod.rs b/crates/rendering/src/decoder/model/mod.rs index a6c6bc01c4b..17803852220 100644 --- a/crates/rendering/src/decoder/model/mod.rs +++ b/crates/rendering/src/decoder/model/mod.rs @@ -760,6 +760,7 @@ fn write_records( outcome, failures, seeds_ran: ran.get(&result.name).cloned().flatten(), + unobserved: Default::default(), problems, summary: summary.join("\n"), repro, diff --git a/crates/verify-expect/src/lib.rs b/crates/verify-expect/src/lib.rs index 15796f9ccfc..f623b92e6d7 100644 --- a/crates/verify-expect/src/lib.rs +++ b/crates/verify-expect/src/lib.rs @@ -391,8 +391,26 @@ fn covered_by<'a>( covered } +/// Classes a case could not measure because an earlier check failed (for +/// example A/V sync when no audio marker could be identified): `(case, +/// class)`.

On main the converter does not keep the source alive until submission, so source 0 renders white. It now writes a case record and is judged against crates/rendering/tests/expectations.toml, where it is a strict macOS expected failure: the run fails if it passes, so the fix has to remove the entry.

A Studio meta without a track start_time is reported as the sync defect it causes. The injected lateness exceeds every sync window, and an injection that finds no frames fails the case.

The A09 sentinel checks the property; removing only the reset keeps its output bit-identical, so that edit is caught by the path warning. --- .github/workflows/engine-verify-os.yml | 8 ++ .github/workflows/engine-verify.yml | 60 ++++++++++++++- .github/workflows/verify-recording.yml | 57 +++++++++++++- crates/audio/src/voice.rs | 32 ++++++++ crates/enc-ffmpeg/src/base.rs | 34 +++++++++ scripts/verify/guards.py | 62 +++++++++++++++ scripts/verify/guards.toml | 100 +++++++++++++++++++++++++ scripts/verify/plan.py | 92 +++++++++++++++++++++++ 8 files changed, 439 insertions(+), 6 deletions(-) create mode 100644 scripts/verify/guards.py create mode 100644 scripts/verify/guards.toml diff --git a/.github/workflows/engine-verify-os.yml b/.github/workflows/engine-verify-os.yml index 31120d23778..1bb925b9d58 100644 --- a/.github/workflows/engine-verify-os.yml +++ b/.github/workflows/engine-verify-os.yml @@ -188,6 +188,14 @@ jobs: scripts/verify/run.sh "${{ inputs.tier }}" --suites "${{ inputs.suites }}" fi + # Equivalent-mutant guards (scripts/verify/guards.toml): a failing + # sentinel is a warning for review, never a failure. + - name: Guard sentinels + if: always() && inputs.platform == 'linux' && matrix.shard == 1 && steps.test.outcome != 'skipped' + continue-on-error: true + shell: bash + run: python3 scripts/verify/guards.py --profile "$CAP_VERIFY_CARGO_PROFILE" + - name: Summary if: always() && steps.test.outcome != 'skipped' shell: bash diff --git a/.github/workflows/engine-verify.yml b/.github/workflows/engine-verify.yml index 41212496da1..9d208f8b4ba 100644 --- a/.github/workflows/engine-verify.yml +++ b/.github/workflows/engine-verify.yml @@ -40,6 +40,10 @@ on: description: "CARGO_LOG for the build (for example cargo::core::compiler::fingerprint=info)" type: string default: "" + base: + description: "Plan from the diff against this ref, like a pull request (scope, risk escalation)" + type: string + default: "" workflow_call: inputs: tier: @@ -63,7 +67,8 @@ jobs: timeout-minutes: 5 outputs: run: ${{ steps.plan.outputs.run }} - tier: ${{ steps.tier.outputs.tier }} + tier: ${{ steps.escalated.outputs.tier }} + escalate: ${{ steps.risk.outputs.escalate }} matrix: ${{ steps.plan.outputs.matrix }} save-cache: ${{ steps.tier.outputs.save-cache }} steps: @@ -110,6 +115,7 @@ jobs: BEFORE: ${{ github.event.before }} MQ_BASE: ${{ github.event.merge_group.base_sha }} MQ_HEAD: ${{ github.event.merge_group.head_sha }} + BASE: ${{ inputs.base }} SUITES: ${{ inputs.suites }} run: | set -euo pipefail @@ -128,16 +134,44 @@ jobs: else gh api "repos/$GITHUB_REPOSITORY/compare/$BEFORE...$GITHUB_SHA" --jq '.files[].filename' > "$files" fi ;; - *) scope=all ;; + *) + if [[ -n "${BASE:-}" ]]; then + gh api "repos/$GITHUB_REPOSITORY/compare/$BASE...$GITHUB_SHA" --jq '.files[].filename' > "$files" + max=3000 + else + scope=all + fi ;; esac echo "scope=$scope" >> "$GITHUB_OUTPUT" echo "max=$max" >> "$GITHUB_OUTPUT" [[ -f "$files" ]] && { echo "$(wc -l < "$files") changed files"; head -50 "$files"; } || true + # High-risk code (scripts/verify/guards.toml): warn, and run a pull + # request that touches it at the FULL tier. + - name: Risk + id: risk + if: steps.files.outputs.scope == 'files' + run: python3 scripts/verify/plan.py risk --files "$RUNNER_TEMP/changed.txt" --summary "$GITHUB_STEP_SUMMARY" --output "$GITHUB_OUTPUT" + + - name: Escalate tier + id: escalated + env: + TIER: ${{ steps.tier.outputs.tier }} + ESCALATE: ${{ steps.risk.outputs.escalate }} + EVENT: ${{ github.event_name }} + BASE: ${{ inputs.base }} + run: | + tier="$TIER" + if [[ "$ESCALATE" == true && ( "$EVENT" == pull_request || -n "$BASE" ) && "$tier" == fast ]]; then + tier=full + echo "High-risk code changed: running the FULL tier." | tee -a "$GITHUB_STEP_SUMMARY" + fi + echo "tier=$tier" >> "$GITHUB_OUTPUT" + - name: Plan id: plan env: - TIER: ${{ steps.tier.outputs.tier }} + TIER: ${{ steps.escalated.outputs.tier }} SCOPE: ${{ steps.files.outputs.scope }} MAX: ${{ steps.files.outputs.max }} SUITES: ${{ inputs.suites }} @@ -156,6 +190,26 @@ jobs: grep -E '^(reason|suites)=' "$RUNNER_TEMP/plan.txt" | sed 's/^/- /' } >> "$GITHUB_STEP_SUMMARY" + # Labels a risky pull request needs-deep-review.

Faulty input, proven by logs independent of the recorder, is now detected directly and the run is retried as inconclusive (a case that stays inconclusive fails as environment): - The stimulus runs its own small ScreenCaptureKit stream, another client in another process. When it receives no frame for more than four stimulus periods while pictures are presented (outside holds), the window server or capture service stalled for every client: in the logged failure the recorder process froze 293 ms with the rest of the VM, the capture service reported Idle while the stimulus changed its picture, and then delivered nothing for 1002 ms while the recorder was idle and responsive. - The synthetic camera and microphone run on their own user-interactive threads (a capture device's callback thread) instead of the recorder's async runtime, where hand-offs ran 20 to 140 ms late, and a hand-off more than 100 ms late inside the recording means the host stalled the source. Cap's own defect gets a dedicated class and strict expectation: past the 2 s drift anchor the recorder stamps camera frames from the processing wall clock instead of their capture time (written pts minus source time 0.00 ms before the anchor, -1.1 to +71 ms after). Camera frame checks before the anchor stay strict timestamp checks (the #2573 class lives there); past it they and the camera-mic offset are reported as camera-clock, and a strict check that past-anchor offsets stay within 4 ms (the microphone's limit) proves the defect in every camera recording.

With that on main the native recycled-pool case passes, and the AVFoundation flakes attributed to it no longer fire with sources retained (sol-avf proof runs and probe 38784185050): cross-fade future frames, the 30 s audio-mix transition and cross-fade future frames, the 120 s jitter export's torn frame and run-to-run differences, and the torn camera frame of camera-pts-late. The recorded-Studio isolated ahead frame was attributed to the same bug by its signature only (0 of 16 with and without the fix in that probe); it is dropped with them so the proof runs on top of #2625 show whether it remains. The native test keeps both of #2625's tests and still writes its case record. --- crates/rendering/tests/expectations.toml | 9 +--- crates/verify/expectations.toml | 55 ------------------------ 2 files changed, 2 insertions(+), 62 deletions(-) diff --git a/crates/rendering/tests/expectations.toml b/crates/rendering/tests/expectations.toml index 10b02520029..403a7e54ad6 100644 --- a/crates/rendering/tests/expectations.toml +++ b/crates/rendering/tests/expectations.toml @@ -1,10 +1,5 @@ # Strict expected failures of the native rendering tests in this directory # (format: crates/verify-expect).

A source that did not obtain or keep real-time scheduling fails the case as harness.

SOURCE_STALL_SECS stays 0.1 s. A late hand-off is inconclusive only when the source thread itself was late; lateness caused by time inside Cap's feed, and any rejected hand-off inside the recording, fail as camera-ingress or mic-ingress and the output checks still run. Rejected frames stay in the truth. A test injects a 4 s slow consumer into both real feeds and requires camera-ingress and mic-ingress. --- crates/verify/tests/recording.rs | 864 +++++++++++++++++++++++++------ 1 file changed, 716 insertions(+), 148 deletions(-) diff --git a/crates/verify/tests/recording.rs b/crates/verify/tests/recording.rs index 353979e3c7d..b22c1af2f66 100644 --- a/crates/verify/tests/recording.rs +++ b/crates/verify/tests/recording.rs @@ -30,7 +30,9 @@ use cap_media_info::{RawVideoFormat, VideoInfo}; use cap_project::{InstantRecordingMeta, RecordingMeta, RecordingMetaInner, StudioRecordingMeta}; use cap_recording::{ NativeCameraFrame, RecordingDefaults, SendableShareableContent, StudioQuality, - feeds::{camera::synthetic::SyntheticCamera, microphone::synthetic::SyntheticMicrophone}, + feeds::{ + Admission, camera::synthetic::SyntheticCamera, microphone::synthetic::SyntheticMicrophone, + }, instant_recording, recovery::RecoveryManager, screen_capture::ScreenCaptureTarget, @@ -41,6 +43,7 @@ use cap_verify::{ audio_code::{self, AudioSource, MarkerPlacement}, fixture_avf, media, report::{self, Case, Tier}, + sched, stimulus::{StimulusEvent, StimulusProcess, StimulusSpec, host_add_secs, host_now, host_secs}, video_code::{self, FrameMarker, Readout, StreamKind}, }; @@ -466,53 +469,98 @@ struct Feeds { stop: Arc, started: Arc, mic_truth: Truth, - mic_task: tokio::task::JoinHandle, - camera_task: Option, SourceLag)>>, + mic_task: std::thread::JoinHandle, + camera_task: Option, SourceTrace)>>, } -/// Hand-offs a synthetic source made late: (seconds from the reference when -/// the frame or chunk was due, seconds late).

Each case record carries the series; a per-process log keeps it for tests that are killed. A wake gap of 100 ms or more proves starvation. Only wall-clock failures are excused by it, and only once: a real-time playback 'dropped' case is recorded as inconclusive, and scripts/verify/retry.py reruns a test whose failures are all inconclusive, or that timed out or hit wgpu's 6.3 s queue drain with the sentinel's evidence, with CAP_VERIFY_RETRY=1. Inconclusive again fails as 'environment'. The job passes only if every failure was retryable and every retry passed. Content, frame identity, timestamps and sync never become inconclusive; a hang without starvation still fails. Bless skips inconclusive records, and the summary lists retried tests with their evidence. --- crates/verify-expect/src/lib.rs | 3 + crates/verify-expect/src/main.rs | 2 +- crates/verify/README.md | 17 ++- crates/verify/src/lib.rs | 1 + crates/verify/src/report.rs | 51 ++++++- crates/verify/src/sentinel.rs | 235 +++++++++++++++++++++++++++++++ scripts/verify/retry.py | 113 +++++++++++++++ scripts/verify/run.sh | 34 ++++- scripts/verify/summary.py | 51 ++++++- 9 files changed, 495 insertions(+), 12 deletions(-) create mode 100644 crates/verify/src/sentinel.rs create mode 100644 scripts/verify/retry.py diff --git a/crates/verify-expect/src/lib.rs b/crates/verify-expect/src/lib.rs index f623b92e6d7..4e6aeaf851d 100644 --- a/crates/verify-expect/src/lib.rs +++ b/crates/verify-expect/src/lib.rs @@ -649,6 +649,9 @@ pub enum Outcome { Fail, Xpass, Unsupported, + /// A wall-clock class failed while the machine starved the process + /// (cap-verify's sentinel); the test is retried once.

A wrong frame on the side with weight q of 0.3 or less leaves residuals of only about q, so the weaker side of the first and last third of every cross-fade went unchecked. read_expecting now also fits every nearby pair (both sides within 12 source frames) and every pair with one side held at its expected frame and the other within 240 frames, and reads the blend as the best alternative when it explains the picture at least 0.05 better than the expected pair. The blend weight tolerance drops from 0.35 to 0.1. Measured on Apple silicon over 614 correct blend frames (export, playback, editing and audio transitions, AVAssetReader and FFmpeg): the expected pair's worst residual is at most 0.086, every alternative fits worse than the expected pair, and the weight error is at most 0.016. The same-clip FFmpeg cross-fade bug now shows 8 wrong frames instead of 6 (2 with the wrong side at weights 0.08 and 0.21). Mutations: an outgoing clip frozen on its first overlap frame (T04) is reported on 158 frames where the frozen side is the weaker one, reversed progress (T05) and reversed real-time playback progress (P02) are caught. --- crates/verify/src/oracle.rs | 69 +++++++++++++++++++++++++++++++++++-- 1 file changed, 67 insertions(+), 2 deletions(-) diff --git a/crates/verify/src/oracle.rs b/crates/verify/src/oracle.rs index 26129b1958c..d96e489528a 100644 --- a/crates/verify/src/oracle.rs +++ b/crates/verify/src/oracle.rs @@ -73,7 +73,19 @@ pub enum MismatchKind { /// Largest allowed difference between a transition frame's measured blend /// weight and the transition progress. -pub const BLEND_PROGRESS_TOLERANCE: f64 = 0.35; +pub const BLEND_PROGRESS_TOLERANCE: f64 = 0.1; + +/// Source frames searched on each side of a cross-fade for a pair that +/// explains the picture better than the expected one. +pub const BLEND_SEARCH: i64 = 12; + +/// Source frames searched on one side of a cross-fade with the other side +/// held at its expected frame (a reader left far behind or ahead). +pub const BLEND_SEARCH_ONE_SIDE: i64 = 240; + +/// How much better (in worst per-cell residual) another pair must fit than +/// the expected pair before the blend is read as that pair. +pub const BLEND_SIDE_MARGIN: f64 = 0.05; #[derive(Clone, Debug, PartialEq, Serialize, Deserialize)] pub struct Mismatch { @@ -471,7 +483,9 @@ pub fn read_expecting( ) -> Readout { use crate::video_code::{self, BLEND_TOLERANCE, FrameMarker}; let StreamExpectation::Blend { - outgoing, incoming, .. + outgoing, + incoming, + progress: expected_progress, } = expectation else { return video_code::read_stream(img, kind); @@ -504,6 +518,57 @@ pub fn read_expecting( if let Some((o, i, p, residual)) = expected && residual <= BLEND_TOLERANCE { + // Both sides are verified: a wrong frame on the weaker side leaves + // residuals of only about its weight, which the tolerance alone would + // accept.

A failure outside it, or with a nonzero metric the bound does not name, is a new failure, with the reason in the case summary. `starved` entries apply only when the case's sentinel saw the machine stall; `hosts` scopes an entry to a machine class (CAP_VERIFY_HOST). - Audio and sync are per source (audio-mic, audio-system, sync-mic, sync-system; real capture per pair), and the Instant oracle's frames missing from the file are frames-missing, never the wall-clock dropped class. - The export/* Windows timestamps entry is now starved-only with the reorder signature (every off-grid frame exactly one period off); the decode-deadline entries link #2636, the decoder entries #2638. - #2632 merged: the Instant processing-clock timestamps and the camera-clock entries are removed. - Real capture checks start and end coverage against the stimulus truth (a first picture later than 0.3 s after the start, or pictures lost before the stop, fail) with self-check injections for both; a skipped system-only case reports unsupported instead of nothing. - The recorded Studio fixture is checked against the frames its generator emitted, so a lost start or final segment cannot just shorten the model. - Cases labelled by decoder confirm the decoder that ran (real-time playback and colour cases on Media Foundation); CAP_VERIFY_UNSUPPORTED_ALLOW lists the cases a runner may skip when CAP_VERIFY_REQUIRE_SUPPORTED is set. - The decoder model keeps each sequence running after a wrong answer, so a seed's recorded classes are its full failure set. --- crates/rendering/src/decoder/model/mod.rs | 31 +- .../tests/iosurface-source-lifetime.rs | 3 + crates/verify-expect/src/lib.rs | 505 +++++++++++++++++- crates/verify-expect/src/main.rs | 31 +- crates/verify/expectations.toml | 458 +++++++++++----- crates/verify/src/pipeline.rs | 4 +- crates/verify/src/report.rs | 185 ++++++- crates/verify/tests/audio.rs | 2 +- crates/verify/tests/common/mod.rs | 29 +- crates/verify/tests/editing.rs | 10 + crates/verify/tests/export.rs | 149 +++++- crates/verify/tests/playback.rs | 7 +- crates/verify/tests/recording.rs | 179 ++++++- 13 files changed, 1376 insertions(+), 217 deletions(-) diff --git a/crates/rendering/src/decoder/model/mod.rs b/crates/rendering/src/decoder/model/mod.rs index 17803852220..b29dac20e08 100644 --- a/crates/rendering/src/decoder/model/mod.rs +++ b/crates/rendering/src/decoder/model/mod.rs @@ -21,7 +21,9 @@ //!

Measured from runs 38841247123, 38844291490 and 38846099909, where counts were identical for the same tier. - Every pull request that changes an engine crate (rendering, editor, export, recording, enc-*, audio, video-decode, project, scap-*, camera*, media and frame conversion, cursor capture, timestamps, the muxer) runs the FULL tier. - CAP_VERIFY_REQUIRE_SUPPORTED=1 on every engine job: an unsupported case fails unless suites.json allows it on that platform with a reason (Windows: */mf, no D3D11 video device on CI VMs). CAP_VERIFY_HOST names the machine class for host-scoped expectations. - The fixture cache key also hashes build scripts, vendor/**, the workspace manifest and the toolchain file. cargo-nextest is pinned to 0.9.148. - The rerun-selection self-check runs after every build. - The summary counts flaky and starvation-only excuses and real-capture second attempts, and no longer counts retry records as cases. - plan.py recording maps changed paths to the real-capture test through the recorder's and the stimulus's dependency closure. --- .../actions/engine-verify-setup/action.yml | 9 +- .github/workflows/engine-verify-os.yml | 12 ++ .github/workflows/engine-verify.yml | 23 +++- scripts/verify/floor.py | 130 ++++++++++++++++++ scripts/verify/plan.py | 124 ++++++++++++++++- scripts/verify/suites.json | 129 +++++++++++++++-- scripts/verify/summary.py | 20 +++ 7 files changed, 421 insertions(+), 26 deletions(-) create mode 100644 scripts/verify/floor.py diff --git a/.github/actions/engine-verify-setup/action.yml b/.github/actions/engine-verify-setup/action.yml index 24295974cbd..b14586b33ee 100644 --- a/.github/actions/engine-verify-setup/action.yml +++ b/.github/actions/engine-verify-setup/action.yml @@ -48,7 +48,7 @@ runs: - name: cargo-nextest uses: taiki-e/install-action@v2 with: - tool: cargo-nextest@0.9 + tool: cargo-nextest@0.9.148 # One cache entry per OS per day (saved by main, nightly and the CI dev # branches), restored by PRs.

A change to a high-risk region or an engine crate runs FULL on macOS 15 and 26. Runs on Blacksmith macOS by default (hosted macOS is reserved for main and release CI and stays a dispatch option), with the setup from ci/verify-recording 9944ca686 and a36245d65: TCC grants for the capturing binaries and the runner ancestry (Screen Recording and per-user Microphone), the display woken and kept awake, BlackHole as the audio device, the stimulus silent unless system_audio is dispatched. The VMs have no hardware H.264 encoder (probe run 38847791287), so recordings there take the libx264 path.

Scheduler-dependent 53.3 ms startup silence partly masks the resulting 60 ms source displacement. The separate product track places each input relative to the mixer start and makes padding timestamp-based; its acceptance is outside this suite integration.

The model is deterministic: Windows reproduces exactly the same classes and seeds, and macOS passes with them. cargo test -p cap-rendering runs the model on every platform (the A/V Sync Tests workflow does on Windows and macOS), so the entries apply everywhere. --- .../src/decoder/model/expectations.toml | 32 ------------------- 1 file changed, 32 deletions(-) diff --git a/crates/rendering/src/decoder/model/expectations.toml b/crates/rendering/src/decoder/model/expectations.toml index 6e5edeafab2..80a6f350a0f 100644 --- a/crates/rendering/src/decoder/model/expectations.toml +++ b/crates/rendering/src/decoder/model/expectations.toml @@ -1034,7 +1034,6 @@ link = "" [[xfail]] case = "decoder-model/ffmpeg/camera-fast/random-seeks/playback" class = "overread" -platforms = ["linux"] seeds = "7" reason = "Camera runaway: when the pts-hole map is full it evicts the narrowest hole, so with two requests per source frame the reader reads one frame further ahead per hole until answers come from the future" link = "https://github.com/CapSoftware/Cap/pull/2595" @@ -1056,7 +1055,6 @@ link = "" [[xfail]] case = "decoder-model/ffmpeg/camera-fast/sequential/export" class = "grid-rounding" -platforms = ["linux"] seeds = "4 11 22 27 29" reason = "Camera runaway: when the pts-hole map is full it evicts the narrowest hole, so with two requests per source frame the reader reads one frame further ahead per hole until answers come from the future" link = "https://github.com/CapSoftware/Cap/pull/2595" @@ -1106,7 +1104,6 @@ link = "https://github.com/CapSoftware/Cap/pull/2595" [[xfail]] case = "decoder-model/ffmpeg/camera/sequential/export" class = "grid-rounding" -platforms = ["linux"] seeds = "0 2 3" reason = "Camera runaway: when the pts-hole map is full it evicts the narrowest hole, so with two requests per source frame the reader reads one frame further ahead per hole until answers come from the future" link = "https://github.com/CapSoftware/Cap/pull/2595" @@ -1128,7 +1125,6 @@ link = "https://github.com/CapSoftware/Cap/pull/2595" [[xfail]] case = "decoder-model/ffmpeg/camera/sequential/export" class = "resets" -platforms = ["linux"] seeds = "0-3" reason = "Found once each sequence keeps running after its first wrong answer (full failure sets, runs 38851482697 and 38851482675): reader starts and seeks exceed the budget of two per jump in the request stream later in the sequence (seed index 0 request 6042).
