Full mode forwards the original native currentTime/playbackRate +accessors and records writes/stacks; events mode leaves those properties intact. +Both modes are opt-in. Diagnostic side observers handle rejection while the +original returned Promise still rejects for the test consumer. + +Initial WebKit serial3 and repeated9 cases pass their caption assertions. The +repeated traces show all six old-core switches resolve while seeking=true; +restoration seeked is delivered30..50ms later. The three candidate switches wait +for restoration. No playback-rate assignment was observed in these source steps. +The successful later user writes occurred after the prior native seeked event. + +The actual-main events-only matrix passes105 assertions, including explicitly +labelled historical overlap/offset defect observations. It again shows early +old-core settlement, including WebKit native seeked43/46ms later.

It cleans both listeners on +completion or failure. There are no fixed delays, seek retries or source rewrites. +It is enabled only with ARTPLAYER_SOURCE_RESTORE_EVENT=1; the default failing +property-based path and existing immediate-call ordering probe remain available. + +With diagnostics disabled, the event control passes27 cases: three repetitions +of three core inputs across three desktop engines using actual main artifacts. +This supports independently verifying captions after native restoration. It is +not proof of a production fix, or sufficient evidence to close the original +immediate-seek failure. Do not make the normal path green by relabelling this +control as the original public API behavior. + +Reports, input/artifact hashes, selected modes, timings and remaining failures are +in [the checkpoint evidence](../baselines/multiple-subtitles-seek-diagnostics.json). +The browser README documents flags.

This tests caption + behavior after restoration; it does not repair the old public switch contract. + +With no flags, the original Promise plus seeking-property path remains unchanged. +The immediate-call ordering probe also remains intact. Record the chosen flags +alongside artifacts: diagnostic overhead may change an intermittent race, and +passing the event control must not replace the original failure evidence. The +combination attachment includes the selected modes and optional native trace. diff --git a/test/browser/multiple-subtitles-combinations.spec.js b/test/browser/multiple-subtitles-combinations.spec.js index 752f14343..85d66e87a 100644 --- a/test/browser/multiple-subtitles-combinations.spec.js +++ b/test/browser/multiple-subtitles-combinations.spec.js @@ -1,6 +1,9 @@ +import process from 'node:process' import { hash } from '../../refactor/scripts/releases.mjs' import { multipleSubtitlesCandidate, multipleSubtitlesHistorical } from '../helpers/multiple-subtitles.js' import { expect, test } from './fixtures.js' +import { switchAfterNativeRestoration } from './source-restoration.js' +import { installSeekDiagnostics } from './source-seek-diagnostics.js' const candidate = await multipleSubtitlesCandidate() const historical = (await multipleSubtitlesHistorical()).filter(item => /^published-.*-main$/.test(item.name)) @@ -15,7 +18,7 @@ test.afterEach(async ({ page }, testInfo) => { return null const track = art.template.$track?.track const read = cue => ({ start: cue.startTime, end: cue.endTime, text: cue.text }) - return { destroyed: art.isDestroy, paused: art.video.paused, time: art.currentTime, offset: art.subtitleOffset, cues: Array.from(track?.cues || [], read), active: Array.from(track?.activeCues || [], read), displayed: art.template.$subtitle?.textContent } + return { destroyed: art.isDestroy, paused: art.video.paused, time: art.currentTime, seeking: art.video.seeking, duration: art.video.duration, readyState: art.video.readyState, offset: art.subtitleOffset, cues: Array.from(track?.cues || [], read), active: Array.from(track?.activeCues || [], read), displayed: art.template.$subtitle?.textContent, trace: window.sourceSeekTrace } }) await testInfo.attach('multiple-combination-final-state', { contentType: 'application/json', body: JSON.stringify(state) }) }) @@ -27,7 +30,9 @@ async function prepare(page, core, implementation, browser, testInfo) { await page.addScriptTag({ content: `(() => { const module = { exports: {} }; const exports = module.exports; ${implementation.code}; window.multipleFactory = module.exports.default || module.exports; })();` }) await page.evaluate(() => window.createPlayer('/test/pattern.mp4')) await expect.poll(() => page.evaluate(() => window.art.isReady)).toBe(true) - await testInfo.attach('multiple-combination-inputs', { contentType: 'application/json', body: JSON.stringify({ core, plugin: implementation.name, pluginSha256: hash(implementation.code), browser: browser.version(), scope: 'Desktop engines; 5.3.0 is adjacent stable, not the unavailable 5.3.1 release; no minimum-version or physical-device claim' }) }) + if (['1', 'events'].includes(process.env.ARTPLAYER_SOURCE_SEEK_TRACE)) + await installSeekDiagnostics(page, process.env.ARTPLAYER_SOURCE_SEEK_TRACE === '1') + await testInfo.attach('multiple-combination-inputs', { contentType: 'application/json', body: JSON.stringify({ core, plugin: implementation.name, pluginSha256: hash(implementation.code), browser: browser.version(), traceMode: process.env.ARTPLAYER_SOURCE_SEEK_TRACE || 'off', sourceRestoration: process.env.ARTPLAYER_SOURCE_RESTORE_EVENT === '1' ?
