os/activity.h or os/log.h. Update cmake files again, hardcoding a Darwin
dependency. The script does not notice that Foundation depends on
CoreGraphics, so add that manually.
Also found that MapKit is supported on WATCHOS but we didn't have dependencies
for that.
Favor one line per supported SDK instead of catch-all dependency lines.
Distinguish from SDKs which have no dependencies vs SDKs which are
unsupported on a particular platform by printing `unsupported` to the
console and remove the line in the cmake file because it should
not exist anyway.
This full cleanup was not done before because of circularity detected by the
util, which has since been fixed.
Support directories with spaces.
From the Swift documentation:
"If you define an optional variable without providing a default value,
the variable is automatically set to nil for you."
This ensures that blocks that come from `DispatchWorkItem`s will
function correctly.
The only exception is __dispatch_barrier_sync() as the block passed to
that call is not `@convention(block)` so it doesn't matter.
Fixes SR-2246.
Adds an explicit @escaping throughout the standard library, validation
test suite, and tests. This will be necessary as soon as noescape is
the default for closure parameters.
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.
* 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.

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
* 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.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.

All generic bridgeable types can bridge for all their instantiations now. Removing this ferrets out some now-unnecessary traps that check for unbridgeable parameter types.
* The buffer-pointer based init methods were passing the dispatch
data default destructor in such a way that the
@convention(block)-ness was lost. This leads to a thunk being passed
to dispatch instead of NULL. Subsequently, dispatch would reference
rather than copy the provided data.
Fixes:
SR-2050 (<rdar://problem/27293973>)
* Several fixits references stale or deprecated methods, or
generated incorrect syntax when applied to actual code.

* Fix DispatchSourceSignal initialisation such that it no longer
registers for the wrong source type.
* Remove (group:) option from DispatchWorkItem, introduce group
options to `.async` methods that accept DispatchWorkItem.
* Rename `DispatchSourceType` to `DispatchSourceProtocol`
* Rework DispatchQueue attributes and flags into a less confusing
approach.

As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
This is a purely mechanical change replacing the attributes with the reserved
spelling. Compilers are to not error when they encounter a reserved spelling
for an attribute which they do not support.
The general rule here is that something needs to be SWIFT_CC(swift)
if it's just declared in Swift code using _silgen_name, as opposed to
importing something via a header.
Of course, SWIFT_CC(swift) expands to nothing by default for now, and
I haven't made an effort yet to add the indirect-result / context
parameter ABI attributes. This is just a best-effort first pass.
I also took the opportunity to shift a few files to just implement
their shims header and to demote a few things to be private stdlib
interfaces.
