📝 WalkthroughWalkthroughJMComic 2.7.7 adds shared runtime scheduling, task-context access, and cooperative cancellation for synchronous and asynchronous downloads. It updates public documentation, release metadata, CI actions, HTTP response validation, and related tests. ChangesRuntime scheduling and cancellation

Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The change is broadly mergeable, but a few localized error-handling, validation, cancellation-test, and documentation issues should be corrected to avoid misleading failures and intermittent coverage.

- Line 281: Update the favorite-album error handling around
require_resp_success_else_raise to pass the normalized album_id so

invalid values from decide_photo_batch_count and decide_image_batch_count are

continuation behavior for valid count_batch values.
- Line 577: Update the validation failures in the sync downloader, including the
check that raises “sync downloader requires JmSyncRuntime” and the corresponding
validation at the nearby second raise, to call ExceptionTool.raises instead of
raising TypeError directly. Preserve each existing error type and message so

- Line 416: Update the photo cancellation test around download_by_photo_detail
to signal readiness from decide_image_save_dir via before_reached, then await
that signal before cancelling. Remove reliance on the single asyncio.sleep(0) so

Capture the controller before scheduling the coroutine.
_run() reads the mutable global current_control when it starts. If the start callback runs again before the first task starts, the first task uses the newer task's controller. The cancel button can then cancel the wrong download. (raw.githubusercontent.com)
Capture a local controller in the closure.

Preserve the requested album ID for missing-album redirects.
When the response redirects to /error/album_missing, require_resp_success_else_raise parses '/ajax/favorite_album'. The parser finds no album ID and raises a parsing error instead of MissingAlbumPhotoException. Pass the normalized album_id through the error-handling path. Add a regression test for this redirect.

Validate count_batch before the empty-input return.
decide_photo_batch_count and decide_image_batch_count can provide invalid values. When do_filter returns no items, execute_on_condition skips the positive-integer validation and the caller continues to after_album or after_photo. Move the existing validation above the empty-input return.

Make the photo cancellation test wait for semaphore readiness.
download_by_photo_detail reaches the locked _photo_semaphore after decide_image_save_dir. The single sleep(0) can let the test cancel at the initial raise_if_cancelled() if an await is added before the acquire. The test then passes without covering queued cancellation. No other test deterministically covers this photo-specific branch. Set before_reached from decide_image_save_dir and wait for it before cancelling.
