Previously, we weren’t suggesting argument labels of enum elements when doing an unresolved member completion. Treat `EnumElementDecl` similar to static `AbstractFunctionDecl`s to show their argument labels.
Fixes rdar://78780690 [SR-14689]
Annotate cross-actor references to global actors as `async` and mark them as not-recommended if they must be executed on a different actor than the current context is on.
Resolves rdar://75902598
Previously we only supported `case` patterns that bound with a `let` inside the associated value like `case .success(let value)`. With this change, we also support `case let .success(value)`.
Fixes rdar://79279846 [SR-14772]
If the completion handler parameter has a default
argument, mark the resulting async function as
`@discardableResult`, as the caller may not care
about the result.
rdar://79190170
If we're going to be classifying nodes in either
an `else if` block or after a `guard` statement
with a known condition path, be more lenient with
unhandled conditions, as we already know what path
they should be classified along.
rdar://78564388
If we're in a case stmt body, any DeclRefExprs
to vars bound by a pattern will actually be to an
implicit var decl that's declared for the body. We
therefore need to walk to its "parent" to get to
the var referenced by the pattern, which will have
the correct entries in the naming and placeholder
maps.
Keep track of patterns that bind multiple vars and
print them out when converting an async call. If
the parameter being bound isn't referenced elsewhere,
we'll print the pattern inline as e.g:
```
let ((x, y), z) = await foo()
```
Otherwise, if the parameter is referenced elsewhere
in the block we'll print the pattern out of line,
such as:
```
let (res, z) = await foo()
let (x, y) = res
```
In addition, make sure to print var bindings out
of line if there's also a let binding, e.g:
```
let x = await foo()
var y = x
```
This ensures any mutations to y doesn't affect x.
If there's only a single var binding, we'll print
it inline.
rdar://77802560
I don't believe this case currently can come up,
but leave it explicitly unhandled for now so we
don't perform an erroneous transform if it ever
comes up in the future.
Previously we were walking them once when visiting
the capture list, and then again as a part of the
pattern binding decl. Change the logic to only
visit them as a part of their pattern binding decl.
* 'super' in a overriding decl is "common".
* type decl introducers (e.g. 'struct', 'enum') at top-level in library
files are "common"
* type decl introducers in 'protocol' are invalid, hence "rare"
* top-level only decl introducer (e.g. 'import', 'extension') are invalid
at non-top-level, hence "rare"
* nested types in function bodies are "rare"
* member only decls (e.g. 'subscript', 'deinit') are invalid in function
body, hence "rare"
* some modifiers (e.g. 'public', 'private', 'override') are invalid for
local decls, hence "rare"

To describe fine grained priorities.
Introduce 'CodeCompletionFlair' that is a set of more descriptive flags for
prioritizing completion items. This aims to replace '
SemanticContextKind::ExpressionSpecific' which was a "catch all"
prioritization flag.
`ClangFileRewriterHelper` only outputs the rewritten buffer when it's
destroyed, but the consumers were never being freed. Cleanup the
lifetime management of the stream and consumers so that they're properly
destroyed.
Rename `DuplicatingSourceEditConsumer` to
`BroadcastingSourceEditConsumer` to better describe its purpose.
We were trying to retrieve the name of all function calls in the body using `getBaseIdentifier`. But calls to `init` don’t have a base identifier, just a `DeclBaseName` (which is special). Work with the `DeclBaseName` internally to prevent the crash.
Fixes rdar://78024731 [SR-14637]
Add an additional case to `CallbackCondition` to
support boolean checks, and add the necessary
classification logic to determine whether a bool
flag check is for a success or failure path.
The logic currently first checks to see if the
async alternative has a convention that specifies
which parameter the flag is, and whether it's a
success or failure flag. If so, it classifies the
flag check accordingly. If there's no async
convention specified, we use a heuristic to see if
the error parameter is force unwrapped in the
failure block. If so, we treat that as the error
path. If there's no force unwrap of the error, we
leave the condition unhandled.
rdar://74063899
- Expand ConditionType to include `.success` and
`.failure` patterns.
- Introduce ConditionPath to represent whether a
classified condition represents a success or
failure path.
- Add methods to CallbackClassifier that deal with
deciding whether a given condition is a success or
failure path.
- Use these methods to simplify `classifyConditional`.

Adapt the `ThrowingEntityAnalyzer` to pick up any
`await` keywords and add an `async` to the extracted
function if necessary along with an `await` for its
call.

'InvalidAsyncContext' depends on the decl context. That may case
"sticky" not-recommended If it's cached for a non-async context.
To workaround this, stop checking 'InvalidAsyncContext' when collecting
completion items for caching. Also consistently use the 'SourceFile' as
the decl context to avoid decl context specific behavior.
