* [ASRunLoopQueue - Performance] Add ASDeallocQueue for efficient object teardown.
This measurably reduces block overhead and context switching. In the layout benchmark,
it increases ops/s while actually reducing CPU utilization. This suggests that we are
now at a lock-bounded local maximum, at least for tri-core devices.
* [ASDeallocQueue] Update convenience helper method and adopt in ASImageNode etc.
* [ASDeallocQueue] Reimplement the queue using a timer-based runloop.
* [Debugging] Re-enable ASDisplayNode Event Log.
* [ASDeallocQueue] Final refinements, comments, code minimization.
* [ASDeallocQueue] Fix for lock release needed in early return (refactoring typo from last commit)
* Remove old deprecated methods. Will restore ones that were removed recently based on PR.
* Update example to use non-deprecated method.
* Don't remove locking / unlocking, insets or willDisplayNode deprecated methods yet.
* Renamed range update callbacks
We finally settled on
didEnter/ExitDisplayState
didEnter/ExitPreloadState
didEnter/ExitVisibleState
This change is meant to unify the range update methods to relate to each
other and hopefully be a bit more self explanatory.
* Guarantee interface callbacks happen on main.
* move fetchData / clearFetchedData to default implementations
* Move deprecated methods to new deprecated category
* Don't bring in cocoapod change.
* Nits
* Capetalize
* [ASTextNode, ASVideoNode] Use ASDisplayNode base class lock for subclass property synchronization
* fix headers to match master
* address @appleguy, @maicki comments
* import header
* Swap lock in ASNetworkImageNode as well
* remove invalid comment
* more cleanup of locks
Summary:
Because we trampoline to main when setting _currentImageQuality, there would be situations where displayWillStart was called, we get a cached image and set currentImageQuality to 1.0, and then a background thread calling setDefaultImage would enqueue an operation that sets currentImageQuality to 0 and overwrites the correct value
Calling _updateProgressImageBlockOnDownloaderIfNeeded should be called without _lock held. We will lock super to read our interface state and it's best to avoid acquiring both locks.
Summary:
Use NSData as key
Add chunking of files
Add support for Animated Images
This adds support for GIF playback in ASDK. It's not currently ready
for merging to public ASDK – for one the GIF decompression may make
more sense in PINRemoteImage.
Removed duration as it wasn't used
Make cover image lazily loaded
Differential Revision: https://phabricator.pinadmin.com/D82033
If previously-displayed contents is gone (e.g. clearContents), and is not finished displaying
by the time the node is onscreen, recreate the placeholder immediately.
Destruction of bigger images in ASNetworkImageNode on the main thread can be expensive and can take some time, so we dispatch onto a background queue to actually dealloc.
