* Give Sequence a top-level Element, constrain Iterator to match
* Remove many instances of Iterator.
* Fixed various hard-coded tests
* XFAIL a few tests that need further investigation
* Change assoc type for arrayLiteralConvertible
* Mop up remaining "better expressed as a where clause" warnings
* Fix UnicodeDecoders prototype test
* Fix UIntBuffer
* Fix hard-coded Element identifier in CSDiag
* Fix up more tests
* Account for flatMap changes
* Add sliceability tests for Unsafe(Raw)BufferPointer.
Improve the generic sliceability tests to verify that SubSequence indices are
compatible with their parents indices.
* Fix and enable testing stdlib Collection instances.
Top-level entry points fully testing a collection instance:
check${Traversal}Collection
One level of recursion into all slices of the collection instance
O(n^2). (Not combinatorial).
Previously, checkCollection() did nothing. So much of the testing infrastructure was inactive. Now it runs all forward collection tests.
Fixes a bug in subscriptRangeTests.
The UnsafeRawBufferPointer and Data collection testing is disabled and
will be fixed in the following commit.
* Give UnsafeRawBufferPointer a distinct slice type.
SubSequence = RandomAccessSlice<Self>
* Fix raw buffer pointer tests after changing the API
* Add UnsafeRawBuffer(rebasing:) initializers.
Allows converting a raw slice into a zero-based raw buffer,
which is a common operation on flat memory.
Add and update UnsafeRawBufferPointer unit tests.
* Do not run recursive O(n^2) collection slice testing on large collections.
Now, even with collection unit testing wired up, the validation tests
take the same amount of time to execute.
* Add init(rebasing:) to UnsafeBufferPointer.
This is required for consistency with UnsafeRawBufferPointer.
* Update CHANGELOG.md for SE-0138 amendment: UnsafeRawBufferPointer slice type.
This revises and expands upon documentation for the standard library's
unsafe pointer types. This includes typed and raw pointers and buffers,
the MemoryLayout type, and some other top-level functions.
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(_:)`.
Changes:
- Added bounds checks to Unsafe*BufferPointer's subscript getter and setter
- Added tests for Unsafe*BufferPointer's subscript getter for all four range types
This documentation revision covers a large number of types & protocols:
String, its views and their indices, the Unicode codec types and protocol,
as well as Character, UnicodeScalar, and StaticString, among others.
This also includes a few small changes across the standard library for
consistency.
Implements SE-0055: https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md
- Add NULL as an extra inhabitant of Builtin.RawPointer (currently
hardcoded to 0 rather than being target-dependent).
- Import non-object pointers as Optional/IUO when nullable/null_unspecified
(like everything else).
- Change the type checker's *-to-pointer conversions to handle a layer of
optional.
- Use 'AutoreleasingUnsafeMutablePointer<NSError?>?' as the type of error
parameters exported to Objective-C.
- Drop NilLiteralConvertible conformance for all pointer types.
- Update the standard library and then all the tests.
I've decided to leave this commit only updating existing tests; any new
tests will come in the following commits. (That may mean some additional
implementation work to follow.)
The other major piece that's missing here is migration. I'm hoping we get
a lot of that with Swift 1.1's work for optional object references, but
I still need to investigate.
