* [License] Simplify the Texture license to be pure Apache 2 (removing ASDK-Licenses)
With permission of the Facebook Open Source team, we are simplifying the Texture
license so that clients can rely on the Apache 2 terms that most of Texture is
already covered by. This means that code originally forked from AsyncDisplayKit
will be re-licensed from "BSD 3-clause + PATENTS v2" to Apache 2 without a
PATENTS file.
After getting confirmation that the updates to these core files look good, we'll
propagate this new license header to all files (in this same PR) and get sign-off
from all parties before landing.
* [License] Update all Texture source files to be pure Apache 2.
* Changelog entry for Apache 2 license update.
* Revert "[License] Update all Texture source files to be pure Apache 2."

* Implement ASCollectionGalleryLayoutDelegate
- It arranges items of the same size into a multi-line stack (say photo gallery or pager). It takes advantage of the fact that its items always have a fixed size to measure as few items as possible while still being able to track their positions at all time. This helps reduce startup/reloadData time, as well as memory footprint.
- It then uses a measure range, which also works as a allocate range, to figure out which items to measure ahead of time. And it guarantees that each item is scheduled to measure only once.
- Lastly, ASCollectionLayoutDelegate has some new methods that allow delegates to hook up and stay ahead of layout attributes requests from the backing view. ASCollectionGalleryLayoutDelegate for example uses these methods to ensure elements that have their layout attributes requested are always ready for consumption, and to measure more elements in the background.
* Handle items that span multiple pages and other improvements in gallery delegate
* Minor fixes
* Fix failing tests
* Fix custom collection example
* Implement missing method in gallery layout delegate
* Fix warnings
* Some improvements
- Collection layout delegates must have a crollable directions property.
- Simplify gallery delegate by not storing unmeasured attributes since calling measure on already measured elements should be cache hits and super fast.
- Abstact some code in gallery delegate to ASCollectionLayoutState+Private and _ASCollectionGalleryLayoutItem.
- Other improvements in gallery delegate
* Fix file licenses
* Move measure range logic to ASCollectionLayout
* Track unmeasured elements
* Remove pending layout in ASCollectionLayout
* Get back pending layout because the timing to latch new data is not ideal
* Add ASCollectionLayoutCache
* Fix file licenses
* Fix xcodeproj
* Add async collection layout to examples/ASCollectionView
* Measure method in ASCollectionLayout to be a class method
* Encourage more immutable states
- Make -calculateLayoutWithContext: to be class methods in ASDataControllerLayoutDelegate and ASCollectionLayoutDelegate.
- Add layout delegate class and layout cache to ASCollectionLayoutContext+Private, to be use by ASCollectionLayout only.
- ASDataController no longer allocates all nodes but lets ASCollectionLayout determine.
- Add scrollableDirections to the layout context since it's often needed by the layout pass. Otherwise users have to wrap it in an info object.
- Update built-in layout delegates and CustomCollectionView example.
- Publish ASHashing. It might be helpful for clients that implement custom collection info objects.
* Remove additionalInfo property in ASCollectionLayoutState
* ASCollectionLayoutState to correctly filter unmeasured elements
* Add ASHashing to umbrella header
* Fix file licenses
* Add ASDispatchAsync and use it in ASCollectionLayout
* Improve code comment in ASCollectionLayoutState
* [ASTextNode2] Provide compiler flag to enable ASTextNode2 for all usages.
The runtime switch is helpful, but is too slow to be shipped in a large
production application where startup time is carefully optimized.
Although this doesn't pass text-related snapshot tests when enabled, it
does allow apps to rely on built-in components like ASButtonNode using
the same text stack as when they are manually creating ASTextNode2
instances.
A simpler approach would be to use a #define ASTextNode ASTextNode2,
but this would create unusual keyword highlighting in code referencing
ASTextNode. However, because it would be less invasive and this is
not on by default, we could do that instead if preferred.
* Update AsyncDisplayKit.h
* [ASTextNode2] Improve naming and documentation of ASTEXTNODE_EXPERIMENT_GLOBAL_ENABLE
* [ASTextNode2] CHANGELOG.md for #410.
* Make ASCellNode indexPath and supplementaryElementKind atomic
* Update the change log
* Fix licenses
* Be explicit with atomic
* Rename the protocol
* And the file
* Introduce ASCollectionViewLayout
- `ASCollectionViewLayout` is an async `UICollectionViewLayout` that encapsulates its layout calculation logic into a separate thread-safe object which can be used ahead of time and/or on multiple threads.
- `ASDataController` now can prepare for a new layout resulted from a change set before `ASCollectionView` even knows about it. By the time the change set it ready to be consumed by `ASCollectionView`, its new layout is also ready.
- New `ASCollectionViewLayoutCalculating` protocol that is simple and generic enough that many types of calculators can be built on top. `ASCollectionViewLayoutSpecCalculator` conforms to `ASCollectionViewLayoutCalculating` protocol and can be backed by any layout spec (e.g `ASStackLayoutSpec`, `PIMasonryLayoutSpec`, etc). We can even build a `ASCollectionViewLayoutYogaCalculator` that uses Yoga internally.
- A built-in `ASCollectionViewFlowLayoutCalculator` that is a subclass of `ASCollectionViewLayoutSpecCalculator` and uses a multi-threaded multi-line `ASStackLayoutSpec` internally. The result is a performant and thread-safe flow layout calculator.
- Finally, `ASCollectionViewLayout` can be subclassed to handle a specific type of calculator with optimizations implemented based on the knowledge of such calculator. For example, `ASCollectionViewFlowLayout` can have a highly optimized implementation of `-layoutAttributesForElementsInRect:`.
Protocolize layout calculator providing and consuming
Add flex wrap documentation
Add a `multithreaded` flag to ASStackLayoutSpec that forces it to dispatch even if it's off main
- Update ASCollectionViewFlowLayoutSpecCalculator to use that flag.
Minor change in ASCollectionViewLayout
Implement Mosaic layout calculator
Minor change
Fix project file
Rename and fix project file
Skip fetching constrained size only if a layout calculator is available
Update examples/ASCollectionView
Remove unnecessary change in ASTableView
Address comments
Rename collection view calculator protocols
Minor changes after rebasing with master
Add ASLegacyCollectionLayoutCalculator for backward compatibility
Remove ASCollectionLayoutSpecCalculator
Remove ASLegacyCollectionLayoutCalculator
Introduce ASCollectionLayout
- A wrapper object that contains content size and an element to rect table.
- Collection layout calculators to return this new object instead of an ASLayout.
Before adding a content cache
Finishing hooking up ASCollectionLayoutDataSource to ASCollectionNode
Stash
Finish ASCollectionLayout
Rough impl of ASCollectionFlowLayout
Revert changes in CustomCollectionView example
Move ASRectTable back to Private
* Rename ASCollectionContentAttributes to ASCollectionLayoutState
* Address other comments
* Introduce ASCollectionLayoutDelegate and make ASCollectionLayout private
* Address comments
* API tweaks:
- Replace `-layoutContextWithElementMap:` in ASCollectionLayoutDelegate with `-additionalInfoForLayoutWithElements:`. The returned object is then stored in ASCollectionLayoutContext for later lookups.
- ASCollectionLayoutContext has no public initializer.
- ASDataControllerLayoutDelegate no longer requires a context of type ASCollectionLayoutContext but simply an `id`. This helps decouple ASDataController and ASCollectionLayout.
- Rename `elementMap` to `elements`.
- Rename `visibleMap` to `visibleElements`.
- Other minor changes.
* Rename ASCGSizeHash to ASHashFromCGSize
* Make sure to call super in -[ASCollectionLayout prepareLayout]
* Update example/ASCollectionView to use ASCollectionFlowLayoutDelegate
* Remove unnecessary change
* Need to check availability before use of macros.
* Get rid of PCH and enforce macro definition.
* Remove prefix
* Switch to global warning instead, much better.
* no message
* Go further
* Make the symbols public so that apps actually build
* Move ASAvailability into the umbrella header
* Remove duplicate define
* Put the file back where it was in the list
* Revert "Put the file back where it was in the list"
This reverts commit 6a80c15b5b5efe5ff39812a018114e8bdc1dc0cf.
