fixes regression remaining after #24092 In #24092 `prepareNode` was updated so it wouldn't try to instantiate generic type symbols (like `Generic` when `type Generic[T] = object`, and `prepareNode` is what `tyFromExpr` uses in most of the compiler. An exception is in sigmatch, which is now changed to use `prepareNode` to make generic type symbols work in the same way as usual. However this requires another change to work: Dot fields and matches to `typedesc` on generic types generate `tyFromExpr` in generic contexts since #24005, including generic type symbols. But this means when we try to instantiate the `tyFromExpr` in sigmatch, which increases `c.inGenericContext` for potentially remaining unresolved expressions, dotcalls stay as `tyFromExpr` and so never match. To fix this, we change the "generic type" check in dot fields and `typedesc` matching to an "unresolved type" check which excludes generic body types; and for generic body types, we only generate `tyFromExpr` if the dot field is a generic parameter of the generic type (so that it gets resolved only at instantiation). Notes for the future: * Sigmatch shouldn't have to `inc c.inGenericContext`, if a `tyFromExpr` can't instantiate it's fine if we just fail the match (i.e. redirect the instantiation errors from `semtypinst` to a match failure). Then again maybe this is the best way to check for inability to instantiate. * The `elif c.inGenericContext > 0 and t.containsUnresolvedType` check in dotfields could maybe be simplified to just checking for `tyFromExpr` and `tyGenericParam`, but I don't know if this is an exhaustive list.
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
