tool maintenance map + +This package is being migrated under PKG-TOOL-THUMB-03. Input ownership and sheet +export are separated; extraction/source cancellation is still being implemented. +Strict TS and published declaration work belongs to PKG-TOOL-THUMB-04.

Normal construction preserves the +existing instance-field order and bound inputChange/ondrop methods. DEFAULTS, +file/video event order, public method spelling and return values stay unchanged. + +Input setup validates options before changing DOM or committed options. A wrapper +receives one owned input; repeated setup with that wrapper reuses it. Replacement +installs the new listeners before releasing the old input. A failed new listener +installation rolls back its partial listeners/DOM. Explicit caller-provided file +inputs are never removed. Generated inputs are removed and the wrapper's previous +position is restored only if its current position still matches the tool's write. +The existing bound ondrop method is now registered correctly. + +Destroy is idempotent and attempts input, video, current URL and destroy-event +cleanup even when one step throws; the first cleanup error escapes afterward. +Setup/file-input/drop/load calls cannot recreate input/source resources after +destruction. The emitter is not globally cleared. This does **not yet** cancel +existing extraction timers or late Blob callbacks; pending work and replaced +source URLs remain tracked risks for the rest of 03. + +Sheet extraction preserves fractional coordinates, historical `creat*` names, +the 30-pixel footer and the filename algorithm. The temporary download anchor is +removed even if click throws. Default aspect-derived height and synchronous video +events currently match workspace 4.4.0; recovered 3.5.31 differs. See the frozen +[contract](../../refactor/baselines/thumbnail-contract.md) before changing defaults. + +## Validation and continuation + +Use Yarn and the repository scripts: + +```sh +yarn test:thumbnail +yarn build artplayer-tool-thumbnail +yarn test:browser test/browser/thumbnail-tool.spec.js test/browser/thumbnail-native.spec.js test/browser/thumbnail-input.spec.js +``` + +`test/thumbnail-input.test.js` contains candidate input/export regressions; set +ARTPLAYER_THUMBNAIL_BASELINE=1 to reproduce failures against frozen workspace +main. ARTPLAYER_THUMBNAIL_ARTIFACT selects an actual built artifact for Node and +browser candidate checks. `test/thumbnail.test.js` remains immutable-behavior +evidence against old implementations, including intentionally reproduced bugs. + +Browser records distinguish actual extraction from native Blob-unavailable +controls. Windows WebKit can load tested MP4 files over HTTP but returns error 4 +for native Blob URLs; this is not successful file extraction. Actual input/DOM +cleanup runs on all three engines, while extraction acceptance needs supported +Safari/WebKit evidence in 05. The independent tool example is +`docs/assets/example/tool.thumbnail.js`, not the external thumbnail plugin example. + +Continue 03 by introducing owned metadata/extraction jobs and source/thumbnail +URL cleanup. Add candidate failure/cancellation regressions and preserve old +tests; do not change default delay/height policy silently. Then migrate the final +module boundaries to strict TS in 04 and verify installed declarations/old paths. +See [task plan](../../refactor/plan.md) and [risk ledger](../../refactor/risks.json). diff

Task 03 remains **doing**: +this checkpoint changes production input ownership and separates sheet/export +logic; extraction jobs and source/Blob cancellation still need implementation. + +## Source changes and compatibility + +`src/input.js` owns generated inputs, wrapper positioning and registered callbacks +in a private WeakMap. Setup validates before mutating committed options/DOM, +reuses an existing owned wrapper input, installs replacement listeners and then +cleans up the previous target. Caller-provided file inputs are retained. Failed +registration removes partial new listeners; failed construction rolls back owned +input/video resources. The historical instance ondrop method is now actually +registered for drop events. This repairs the undefined static callback defect. + +Destroy is idempotent and attempts all input/video/current-URL/event cleanup even +when a cleanup step throws. It preserves the first cleanup failure. Mutating the +public option field does not erase the input ownership record. After destruction, +setup/inputChange/ondrop/loadVideo cannot allocate new input/source resources. +Wrapper position is restored only when it still matches the tool's relative write. + +`src/sheet.js` contains midpoint coordinates, footer/canvas creation and download +anchor handling. Historical calculations, attribution, creat* spellings and +filename behavior stay unchanged. Download removes its temporary anchor even if +click fails. The public class delegates existing methods rather than adding new +public entry points. Constructor fields/order, direct class exports, defaults, +event timing and chaining remain covered. Runtime source is still JS pending 04; +emitter provenance and public declarations are not claimed complete. + +The package now has an actual ARCHITECTURE.md map, maintenance commands, ownership +rules and explicit continuation boundaries. Normal package builds regenerate +main/legacy/ESM plus docs copies. No hand editing of generated artifacts occurs. + +## Evidence + +`test/thumbnail-input.test.js` adds 14 candidate regressions. The unchanged tests +on frozen workspace main produce **2 passes/12 failures**. Source and both built +UMD variants pass all 14. These include real defect contrasts and compatibility +checks, not only assertions that new helper functions exist. + +Browser candidate coverage is added alongside frozen implementations. A separate +native DOM test selects files through generated inputs, replaces/reuses wrappers, +dispatches events to old detached inputs, verifies listener removal, restores +styles and verifies cleanup when a destroy listener throws. It runs without +requiring Blob media decoding and therefore also executes on Windows WebKit. + +Each source/main/legacy run contains 54 rows: 32 actual tool scenarios in +Chromium/Firefox across old and candidate versions, 3 candidate input/DOM scenarios +across all engines, 16 Windows WebKit Blob-unavailable controls and 3 native media +comparison tests. The 16 controls are not successful extraction. Old defect rows +remain unchanged; candidate drop and repeated-destroy expectations reflect fixes. +The candidate late-Blob and replacement-URL scenarios still reproduce outstanding +03 defects, explicitly preventing a claim of complete lifecycle repair. + +Final logs, per-case measurements, artifact hashes and CI results are recorded in +`refactor/baselines/thumbnail-input-checkpoint.json`. The current coverage policy +only measures core/chapter; no thumbnail coverage percentage is claimed here. +No hosted CI, physical Safari acceptance, npm publish or version bump occurred. + +## Remaining work and rollback + +Finish 03 with owned metadata waiting, extraction jobs, native error handling, +source/thumbnail URL lifetime and cancellation/late-callback protection. The +current pending extraction behavior is intentionally not declared fixed. Test +failure-path reentrancy during constructor/setup cleanup as part of that ownership +pass. Preserve the frozen default delay/height conflict until a concrete policy +is documented. Task 04 owns strict TS, emitter attribution and missing types; +05/06 retain full media/core integration, Safari/WebKit and distribution gates. +All thumbnail risks remain open. Revert this checkpoint and run the normal package +build to roll back the input/sheet change. The task completion count does not change. diff --git a/refactor/plan.md b/refactor/plan.md index 4d7b6b6d8..10c360fc6 100644 --- a/refactor/plan.md +++ b/refactor/plan.md @@ -4,7 +4,7 @@ 基线：`40fcda6a37d0049d42e49c1e64e70d4fd9ba5f7f`。总任务 222 项，范围 22 个包及工作区/示例。 -状态：todo 101 / doing 10 / blocked 0 / done 111 / deferred 0。风险 L/M/H 表示兼容风险，不表示工期。 +状态：todo 100 / doing 11 / blocked 0 / done 111 / deferred 0。风险 L/M/H 表示兼容风险，不表示工期。 前置依赖是启动条件；验收是完成条件。任务可以继续拆分，但不能复用或悄悄删除旧 ID。 @@ -357,7 +357,7 @@ | --- | --- | --- | --- | --- | --- | --- | | PKG-TOOL-THUMB-01 | artplayer-tool-thumbnail
