* Private members may not satisfy protocol requirements, ever.
...because by construction they can be invoked from outside of the
type.
Finishing up SE-0025 ('private' and 'fileprivate').
* Update docs and mark SE-0025 ('private' and 'fileprivate') as done!
There's still improvements we can make (see 508e825f), but the feature
is in place and should be working correctly.
As of now:
* old APIs are just marked as `deprecated` not `unavaiable`. To make it
easier to co-operate with other toolchain repos.
* Value variant of API is implemented as public @private
`_ofInstance(_:)`.
Update for SE-0107: UnsafeRawPointer
This adds a "mutating" initialize to UnsafePointer to make
Immutable -> Mutable conversions explicit.
These are quick fixes to stdlib, overlays, and test cases that are necessary
in order to remove arbitrary UnsafePointer conversions.
Many cases can be expressed better up by reworking the surrounding
code, but we first need a working starting point.
This iterator uses an inline 32-byte buffer so it doesn't have to call
copyBytes(to:count:) for every single byte. It results in an approximate
6x speedup on my computer.
* DispatchTimeInterval's internal interval computation should be
done with signed integers to allow for negative intervals. This
moves all the unsigned conversions out to the API calls that can
only accept positive intervals (timer sources and IO interval) and
allows intermediate TimeIntervals to have a negative value.
* _swift_dispatch_data_create should have been marked as returning a
retained object, otherwise the object is never fully released and
the destructor is never executed.

This iterator uses an inline 32-byte buffer so it doesn't have to call

Several libdispatch APIs in Queue.swift are annotated as:
public enum GlobalQueuePriority {
@available(OSX, deprecated: 10.10, message: "Use qos attributes instead")
@available(*, deprecated: 8.0, message: "Use qos attributes instead")
case high
This annotation means ".high is deprecated on all OSes in version 8.0 and
above", so the compiler had false positive deprecation warnings on macOS
when the minimum deployment target is 10.9 and false negatives on watchOS
when the deployment target is 2.0.
The fix is to explicitly enumerate the platforms the API is deprecated on. This
is not ideal (see SR-2155) but avoids the false positives and negatives.
This fixes https://bugs.swift.org/browse/SR-2153
This is another necessary step in introducing changes
for SE-0107: UnsafeRawPointer.
UnsafeRawPointer is great for bytewise pointer operations.
OpaquePointer goes away.
The _RawByte type goes away.
StringBuffer always binds memory to the correct CodeUnit
when allocating memory.
Before accessing the string, a dynamic element width check
allows us to assume the bound memory type.
Generic entry points like atomicCompareExchange no longer handle
both kinds of pointers. Normally that's good because you
should not be using generics in that case, just upcast
to raw pointer. However, with pointers-to-pointers
you can't do that.
These provide the same functionality as the one-argument versions for both
2 and 3 argument closures. Since these are less common, the same thing can be
achieved by composing the one-argument version. rdar://problem/26529498
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.
As proposed in SE-0107: UnsafeRawPointer.
`void*` imports as `UnsafeMutableRawPointer`.
`const void*` imports as `UnsafeRawPointer`.
Occurrences of `UnsafePointer<Void>` are replaced with UnsafeRawPointer.
* Migrate overlays from UnsafePointer<Void> to UnsafeRawPointer.
This requires explicit memory binding in several places,
particularly in NSData and CoreAudio.
* Fix a bunch of test cases for Void->Raw migration.
* qsort takes IUO values
* Bridge `Unsafe[Mutable]RawPointer as `void [const] *`.
* Parse #dsohandle as UnsafeMutableRawPointer
* Update a bunch of test cases for Void->Raw migration.
* Trivial fix for the SceneKit test case.
* Add an UnsafeRawPointer self initializer.
This is unfortunately necessary for assignment between types imported from C.
* Tiny simplification of the initializer.
We can express the same using the `isUniquelyReferencedNonObjC` API.
- Rename `isUniquelyReferencedNonObjC` to `isKnownUniquelyReferenced`.
- Cleanup `ManagedBufferPointer` by removing holdsUniqueOrPinnedReference` and
renaming `holdsUniqueReference` to `isUniqueReference`.
- No longer promise to return false from `isKnownUniquelyReferenced` for @objc
class instances.
