In the IDEA plugin update there are a code that used system property
"idea.plugins.compatible.build" to calculate the IDEA version
that will be sent to plugin marketplace to download last version of
the plugins. It seems like by some reason setupIdeaStandaloneExecution()
was called from the IDEA thread and because of that idea version was
calculated incorrectly and incorrect version of the plugins was
downloaded.
It is still unclear how the setupIdeaStandaloneExecution() could be
called from the IDEA, so added logging for that.
Relevant issue: MP-3702

Apparently, it's not enough to run psi2ir for all modules, and then
backend for all modules. If there are several modules in the chunk, IR
in any one of them can reference IR of any other one after psi2ir.
So we would end up in a situation where we're running codegen for the
first module, but the second module is completely unlowered. This would
break some assumptions in the codegen, for example in KT-49575, codegen
would see a reference to a top-level function from another module, and
would fail because the function has no containing class (since file
facades have not been generated yet!), and thus must be an intrinsic,
yet no such intrinsic is known to the codegen.
The solution is to run lowerings first on all modules, and then run
codegen on all modules. The kind of error explained above shouldn't be
possible anymore, because lowerings have to deal both with lowered and
unlowered code from other files all the time, so lowerings can't assume
that reference from other module is lowered either (or unlowered).
The code is not very nice, but hopefully it can be improved as soon as
we get rid of the old JVM backend (and maybe later with the migration to
FIR too).
#KT-49575 Fixed
This will be used for two purposes:
1) call lowerings and codegen separately from
KotlinToJVMBytecodeCompiler to support cyclical module dependencies
(KT-49575)
2) split lowerings and codegen into separate modules
The kdocs were almost self-evident, as opposed to the fact that
JvmClasspathRoot is unused in the project, which could make it a victim
of an innocent refactoring.
... and the compiler argument -Xskip-runtime-version-check.
The vast majority of warnings reported by this checker in practice has
proven to be false positives. In addition to that, it was needlessly
verbose, and also completely untested.
If we decide to reintroduce some of these checks, it's probably a better
idea to perform them in tools, such as Kotlin Gradle plugin, which
usually have slightly more information about the way the project is
built and can suggest some meaningful solutions (as opposed to "remove
this jar $HOME/.gradle/... from the classpath" which was the best
JvmRuntimeVersionsConsistencyChecker could do.)
#KT-27256 Obsolete
#KT-41664 Fixed
Those modules are:
- :compiler:fir:providers, which contains Fir and Symbol providers,
scopes, and different utilities used by them
- :compiler:fir:semantics, which contains different abstractions and
entities which are used in resolution and in checkers
- :compiler:fir:resolve, which contains all stuff related to resolution
and inference
There are two pros of this change:
1. It may increase gradle build, because it allows to compile :fir:resolve
and :fir:checkers modules in parallel
2. Logic of working FIR (scopes, providers, DFA logic system, etc) is
now separated from logic of resolution phases, so for example checkers,
which are depend on scopes physically will not be able to run resolve
in any way
Instead of a Boolean flag -Xserialize-ir, use modes: none,inline,all.
In "inline" mode, only information needed to deserialize bodies of inline
functions is serialized.
In the "all" mode, all declarations are serialized completely.
