StdlibUnittest is built with `-disable-implicit-concurrency-module-import`
and it uses concurrency feature. Therefore, without explicit import,
StdlibUnittest.swiftmodule doesn't have `IMPORTED_MODULE` entry of
`_Concurrency`. And it results link-failure when static linking because
swift_Concurrency is not linked.

Remove the option that explicitly enables concurrency back-deployment,
and instead always enable its support in the compiler. Remove the use
of the extraneous CMake option as well.
When build-script is given `--back-deploy-concurrency`, also use that
to build other parts of Swift with the back-deployed versions:
* The compiler allows async and actors to be defined with the
back-deployed availability, e.g., the same as `-Xfrontend
-enable-experimental-back-deploy-concurrency`. (The latter will go
away soon)
* The standard library unit testing framework and distributed actors
library are build with the older OS versions.
* The tests use the older OS versions, with some adjustments to make
them agnostic to the back-deployment setting.
The support for running concurrency tests individually with filters
invoked the non-concurrent supporting `runOneTest` accidentally. Fix
this to us the `runOneTestAsync` allowing the single async test to be
run in process again. This is needed for ease of debugging (and in the
case of Windows, the only option for debugging).

For various reasons, it can be useful/interesting to create builds of
Swift that minimize dependencies. Let's try to keep that working as long
as we can.
This patch plumbs through the ability to run async code in the standard
library unittests. The async start-point is `runAllTestsAsync` and must
be called from an async context. For now, that means calling through
async-main.
This replaces swiftMSVCRT with swiftCRT. The big difference here is
that the `visualc` module is no longer imported nor exported. The
`visualc` module remains in use for a singular test wrt availability,
but this should effectively remove the need for the `visualc` module.
The difference between the MSVCRT and ucrt module was not well
understood by most. MSVCRT provided ucrt AND visualc, combining pieces
of the old MSVCRT and the newer ucrt. The ucrt module is what you
really wanted most of the time, however, would need to use MSVCRT for
the convenience aliases for type-generic math and the deprecated math
constants.
Unfortunately, we cannot shadow the `ucrt` module and create a Swift SDK
overlay for ucrt as that seems to result in circular dependencies when
processing the `_Concurrency` module.
Although this makes using the C library easier for most people, it has a
more important subtle change: it cleaves the dependency on visualc.
This means that this enables use of Swift without Visual Studio for the
singular purpose of providing 3 header files. Additionally, it removes
the need for the installation of 2 of the 4 support files. This greatly
simplifies the deployment process on Windows.
Clean up a few general patterns that are now obviated by canImport
This aligns more generally with the cleanup that the Swift Package
Manager has already done in their automated XCTest-plumbing tool in
apple/swift-package-manager#1826.
Previously, metadata prespecialization for classes only occurred when
all of a specialized generic class's ancestors were themselves generic.
Here, that requirement is lifted so that generic classes with concrete
ancestors are also eligible for prespecialization.
This replaces `LLVM_LIBRARY_VISIBILITY` with `SWIFT_LIBRARY_VISIBILTIY`
througout the runtime. The purpose of this attribution is unclear -
building with `-fvisibility=hidden` would accomplish this. This is an
entirely mechanical change replacing the macro with the Swift namespaced
variant instead.
Commit for CMake and build scripts to recognize OpenBSD. To keep this
commit relatively short, this just deals with the rather simple and
uncontroversial changes to the build system.
Note that OpenBSD calls "x86_64" as "amd64", Since the Swift stdlib will
be put in a subdirectory named after ARCH, to ensure the standard
library is properly found later, we use the native architecture name for
OpenBSD in the build system rather than trying to deal with the
difference the other way around.
These should hopefully all be uncontroversial, minimal changes to deal
with progressing the build to completion on OpenBSD or addressing minor
portability issues. This is not the full set of changes to get a
successful build; other portability issues will be addressed in future
commits.
Most of this is just adding the relevant clauses to the ifdefs, but of
note in this commit:
* StdlibUnittest.swift: the default conditional in _getOSVersion assumes
an Apple platform, therefore the explicit conditional and the relevant
enums need filling out. The default conditional should be #error, but
we'll fix this in a different commit.
* tgmath.swift.gyb: inexplicably, OpenBSD is missing just lgammal_r.
Tests are updated correspondingly.
* ThreadLocalStorage.h: we use the pthread implementation, so it
seems we should typedef __swift_thread_key_t as pthread_key_t.
However, that's also a tweak for another commit.
Misaligned indices were fixed in 5.1, but we should disable the test
when testing back deployment.
Adds a shared helper to StdlibUnittest for the run time check.
There are situations where you want to build against a libc that is out
of tree or that is not the system libc (Or for cross build scenarios).
This is a change for passing the -sdk and include paths for things like
this.
This was already being done for the stderr, but not for stdout. Doing
this means that we no longer get spurious carriage returns on the stdout
output stream on Windows. This is needed for supporting the
validation test suite on Windows.
The comment in the function said:
// This function is implemented in Objective-C because Swift does not support
// failing initializers.
which hasn't been true since swift 1.1.
StdlibUnittest uses an AtomicBool to track whether a failure has ocurred
in a test. Before this, expectFailure could have a false-positive
failure due to a race condition on the _anyExpectFailed.
The following interleaving would trigger the issue:
A: loads false
A: stores false
B: loads false
A: stores true
B: stores false
A: loads false (after body)
This causes A to see a false-positive failure.
This allows the conversion of the Windows `BOOL` type to be converted to
`Bool` implicitly. The implicit bridging allows for a more ergonomic
use of the native Windows APIs in Swift.
Due to the ambiguity between the Objective C `BOOL` and the Windows
`BOOL`, we must manually map the `BOOL` type to the appropriate type.
This required lifting the mapping entry for `ObjCBool` from the mapped
types XMACRO definition into the inline definition in the importer.
Take the opportunity to simplify the mapping code.
Adjust the standard library usage of the `BOOL` type which is now
eclipsed by the new `WindowsBool` type, preferring to use `Bool`
whenever possible.
Thanks to Jordan Rose for the suggestion to do this and a couple of
hints along the way.
When testing runtime lookup changes, we want to make sure each test runs in isolation. Add a new modifier, `.requireOwnProcess()`, to enable tests to guarantee they’re run in isolation.
Windows uses carriage returns and newlines. The string matching is
sensitive to this. Simply erase carriage returns from the standard
error stream to compensate.
