This reverts commit 6238e5edbde55fb82982ce4a19a0cbca7fe7eb9d.
We will re-apply this change, but there are some early signs of performance impacts that need to be investigated.
* Before truncate a text storage in ASTextKitContext reset the text storage to original value
* Fix ASTextNode tests
We should pass in the constrained size in both cases and the sizes should be the same. We adjust the calculated size in ASTextNode to be a bit narrower in the second case if we truncate again with the calculated size as constrained size it will truncate more and the resulting size will shrink.
* Perhaps controversially, decomposing ASRangeControllerUpdateRangeProtocol+Beta.h such that the categories on various classes are defined in the classes themselves since that's where the implementation of those categories is provided.
* Updating unit tests and import other headers the tests took for granted. The tests could probably import the umbrella header and not have to worry about this.
* Updating the "Life without Cocoapods" sample to build and run dependent on ASDK as a static library.
* Added a "Life With Frameworks" sample app to build and run dependent on ASDK as a framework, proving the framework targets work.
Currently measurement always needs to happen on the main thread if implicit hierarchy management is enabled as adding and removing from nodes needs to happen on the main thread. We now will trampoline to the main thread to do the insertion and deletion of nodes.
This also resolves the issue that can occur if a node is already loaded deep in the layout hierarchy in the layout that the node is transforming to. Before insertion or deletion is happening we need to crawl the layout hierarchy to check that though.
* [ASTableView] constrainedSizeForRowAtIndexPath
* Quick fix to header file
* Switch to Delegate from DataSource.
* Update testing variables to reflect switch to delegate
* [ASDataController] Add some assertions to clarify what queues things happen on
* [ASCollectionDataController] Optimize willReloadData
* [ASDataController] Minor optimizations, no functional changes
* [ASDataController] Always reload data on _editingTransactionQueue
* [ASDataController] Remove async data fetching option, deprecate callbacks
* [ASDataController] Not mutable
* [ASMultidimensionalArrayUtils] Use fast enumeration
* Optimize ASMultidimensionalArrayUtils
* Fix some concurrency problems detected by Xcode 8's new Thread Sanitizer.
Some of these changes are arguably just to silence the warnings from Thread Sanitizer.
* Fix several memory leaks in the unit tests.
A number of the unit test source files are compield with `-fno-objc-arc`. This was clearly overlooked when writing several of the unit tests.
Fixed by (mostly) switching to use of `-autorelease` for the problem code.
NOTE: This commit doesn't fix all the memory leaks found. There's still at least one leak in `-[ASDisplayNodeTests testSetNeedsDataFetchImmediateState]`, and several leaks in `ASBasicImageDownloader.mm`. I wasn't able to find a trivial cause to these, unfortunately.
