This commit doesn't change behaviour of any inference algorithm, it
introduces opportunity to switch constraint system that is used for
overload resolution and fix problematic cases by changing one enum
entry.
Due to fundamental changes, there are cases where a new inference
algorithm reports overload resolution ambiguity errors (#KT-31670,
#KT-31758), which is correct from its point of view. However, this is
a breaking change and to really make it, we should be very confident
and have enough motivation for it, therefore, we don't change behavior
now in order to collect more examples (if there are any). And if we
find a lot of erroneous examples, we'll be able to change the behavior
quite simply
This is a large commit, which introduces general API for working with
abstraction of Platform.
- Add new abstraction to 'core' - SimplePlatform - which represents
exactly one platform
- Clients are strongly prohibited to create instances of SimplePlatform
by hand, instead, corresponding *Platforms abstraction should be used
(e.g. JvmPlatforms, JsPlatforms, KonanPlatforms)
- Move TargetPlatform to 'core', it represents now a collection of
SimplePlatforms
- Clients are strongly encouraged to use TargetPlatform
(not SimplePlatform) in API, to enforce checks for multiplatform
- Provide a helper-extensions to work with TargetPlatform
(in particular, for getting a specific component platform)
- Remove MultiTargetPlatform in favour of TargetPlatform
- Notably, this commit leaves another widely used duplicated abstraction,
namely, IdePlatform. For the sake sanity, removal of IdePlatform is
extracted in the separate commit.
Up-to-date check is very heavy for intellij repo due to artifact size.
If module directory in repo is written only by one task we can assume
that task if up-to-date if target directory exists.
Inline function descriptor in derived class represented as FAKE_OVERRIDE.
So we should find it in base class declaration
(not interface cause inline function can't be virtual, but always final)
and then check class version.
#KT-29402 Fixed
Declare AnalysisFlags in module 'frontend', and JvmAnalysisFlags in
module 'frontend.java', to avoid leaking Java-related logic to common
compiler code
This is effectively a revert of
447c127036, which was an (incorrect) fix
for KT-22379.
The bug was that we've cleared data-flow info for assigned variables
*after* knowledge that loop condition if 'false' was applied (we can
claim that if loop has no jump-outs). Therefore, we broke smartcasts in
the innocent code like that:
var x: Int? = null
while (x == null) {
x = readPotentiallyNullableInt()
}
// x should be non-null here
Commit reverts that "fix" for 1.3.0 and postpones deprecation until 1.4
