* [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."
This reverts commit ffa0fbbba9717d871dd16c4b07539f2f8208fc2b.
* [License] Update all Texture source files to be pure Apache 2, maintaining copyrights.
* [License] Update CONTRIBUTING, README, Podspec & Dangerfile.
Doing so may trigger `-layer:didChangeBoundsWithOldValue:newValue:` on the layer's delegate (i.e `ASCALayerExtendedDelegate`) which then runs other operations that require the lock to be free.
- Rename `ASDisplayNodeAssertLockUnownedByCurrentThread` to `ASAssertUnlocked`, and `ASDisplayNodeAssertLockOwnedByCurrentThread` to `ASAssertLocked` -> shorter and hopefully easier to distinguish between the two.
- Add assertions to `_locked_` and `_u_` (i.e "unlocked") methods.
- Turn `CHECK_LOCKING_SAFETY` flag on by default. After #1022 and #1023, we're in a good shape to actually enforce locked/unlocked requirements of internal methods. Our test suite passed, and we'll test more at Pinterest after the sync this week.
- Fix ASVideoNode to avoid calling `play` while holding the lock. That method inserts a subnode and must be called lock free.
- Simplify `_loaded(node)` to only nil-check `_layer` because regardless of whether the node is view or layer backed, the layer should always be set if loaded. Use it throughout.
- Other minor changes.
* [ASDisplayNode] Add safeAreaInsets, layoutMargins and related properties to ASDisplayNode
* Add layoutMargins bridged to the underlying view
* Add safeAreaInsets bridged to the underlying view
* Add fallback calculation of safeAreaInsets for old iOS versions
* Add automaticallyRelayoutOnSafeAreaChanges and automaticallyRelayoutOnLayoutMarginsChanges properties
* Add additionalSafeAreaInsets property to ASViewController for compatibility with old iOS versions
* Provide safeAreaInsets for layer-backed nodes.
This also fixes tests.
* Fix crash when insetsLayoutMarginsFromSafeArea is set from a background thread
* Changes requested at code review:
* Update documentation for layoutMargins and safeAreaInsets properties. Suggest that users set the automaticallyRelayout* flags to ensure that their layout is synchronized to the margin's values.
* Fix accessing ASDisplayNode internal structures without a lock.
* Add shortcut in -[ASDisplayNode _fallbackUpdateSafeAreaOnChildren] to skip a child when possible.
* Add shortcut in ASViewController to avoid fallback safe area insets recalculation in iOS 11. Fix fallback safe area insets recalculation when the additionalSafeAreaInsets are set.
* Add debug check that a view controller's node is never reused without its view controller, so the viewControllerRoot flag value is always consistent.
* Use getters instead of reading ivars directly in -layoutMarginsDidChange and -safeAreaInsetsDidChange.
* Minor change in CHANGELOG
* Minor change in ASDisplayNodeTests.mm
* Make display node, layout spec, and style conform to NSLocking so that users/subclasses can access their locks

[ASControlNode+Private] Adds private category for ASControlNode to
access private selectors
* [NSParagraphStyle+ASText] Fixes typo related to testing

attribute _alone_ (would not be caught by unsupported attributes
check)
* [ASMultiplexImageNode] Bump availability check to support < Xcode 9
* [ASTraitCollection] Fixes typo that was causing build to fail
* Clean up formatting to adhere to character/line limit + braces
- Failing to do so will introduce race conditions in which the property was updated on a background thread but main thread has not executed the block that updates the property of the node's layer. During that window, the layer's property is out-of-date and can't be used.
- After this change, ASDisplayNode's cornerRadius is the only source of truth and users must always use it instead of CALayer's.
* Added attributed versions of accessibilityLabel, accessibilityHint and accessibilityValue
* Follow conventions for property types
* Use curly braces
* Update changelog
* Follow conventions for property types in UIView+ASConvenience.h
* Add compatibility for Xcode 8
* Use isEqualToString instead of pointer comparison
* Only allocate attributed strings once. Use _setAttributedAccessibilityToViewAndProperty only for attributed properties.
* [ASCornerRounding] Initial (untested) implementation of ASCornerRounding features.
* [ASCornerRounding] Working version of both clip corners and precomposited corners.
* [ASCornerRounding] Improve factoring and documentation of corner rounding features.
* [ASCornerRounding] Some final fixups.
* Add entry to changelog for .cornerRoundingType
This makes it much easier to use the ASCoreAnimationExtras method which offers by
far the most efficient way to display a stretchable image.
In the future, we should move that function to UIImage+ASConvenience or another
header where it can be more easily found and enjoyed!
* Lock released between add to pend controller and modifying pend state
The existing design is pretty fraught with error. We should probably
rethink this but in the meantime, this fixes a bug where calling
setNeedsLayout can start failing for nodes.
Essentially the method ASDisplayNodeShouldApplyBridgedWriteToView has
a side effect of registering a node to apply it's pending state *if*
it doesn't currently need the pending state applied. My guess is this
was to avoid continually registering the node and this behavior actually
helped expose this bug.
The bug: after the node is registered for flushing it's state, several
code paths released the lock before applying that state to the pending
state object. Before it could re-obtain the lock to apply it to the pending
state, the pending state controller flushed it on the main thread.
On subsequent calls to setNeedsLayout, the pending state had pending state
already (from previous calls which missed the flush) and thus wasn't
registered for future flushing.
* Add changelog
* [ASDisplayNode] Convert isSynchronous to an Objective-C atomic BOOL.
This reduces lock contention, and should also fix a very rarely seen deadlock.
* [ASDisplayNode] Implement a std::atomic-based flag system for superb performance
Although Objective-C atomics are equally fast, or better that std::atomic when
access through method calls, for the most intense use cases it is best to avoid
method calls entirely.
In ASDisplayNode, we could benefit significantly from avoiding both method calls
(already true today) but also avoid locking the mutex, for both CPU and contention
gains.
There will still be many methods that need locking for transactional
consistency - however, there are currently dozens of accessor methods that could
avoid frequent lock / unlock cycles with use of atomics, and other usages of the
ivars directly where locking could be delayed until after early-return conditions
are checked and passed.
* [Yoga Beta] Improvements to the experimental support for Yoga layout.
Yoga remains an unsupported / speculative feature, but these improvements are important for
the functionality of clients that are experimenting with it.
For example, without these changes, ASButtonNode is not able to lay out correctly. These
changes allow certain subtrees that use layout specs to coexist properly in a Yoga heirarchy.
The most significant change here is moving ASEdgeInsets into the #if YOGA gating. Although
this is technically an API change, this type was added with no known use cases and is
really only useful for flexbox layout specification. So, before usages of it are created,
it makes sense to constrain the Texture API surface until that time.
* [RTL] Bridge the UISemanticContentAttribute property for more convenient RTL support.
Although apps could handle this before by setting the view's property in didLoad, it's
useful to bridge this property for setting during off-main initialization.
This change also makes RTL fully functional / automatic for Yoga layout users.
* Remove RTL property addition and depend on PR #60 landing first.
* Fix warnings
* Add line to changelog

* Add a thread-safe layoutIfNeeded implementation to ASDisplayNode

* Update comments
* Don't wait until updates are committed when the collection node enters display state
