* Fix #22826: Don't skip generic instances in type comparison (#22828)SirOlaf2023-10-211-0/+8
| | | | | | | | | | | | | | Close #22826 I am not sure why this code skips generic insts, so letting CI tell me. Update: It has told me nothing. Maybe someone knows during review. Issue itself seems to be that the generic instance is skipped thus it ends up being just `float` which makes it use the wrong generic instance of the proc because it matches the one in cache --------- Co-authored-by: SirOlaf <>
* fixes #22753; Nimsuggest segfault with invalid assignment to table (#22781)ringabout2023-10-021-2/+2
| | | | | | | | fixes #22753 ## Future work We should turn all the error nodes into nodes of a nkError kind, which could be a industrious task. But perhaps we can add a special treatment for error nodes to make the transition smooth.

* Fix #21742: Check generic alias depth before skip (#22443)SirOlaf2023-09-081-0/+10
| | | | | | | | | | | | | | | Close #21742 Checking if there's any side-effects and if just changing typeRel is adequate for this issue before trying to look into related ones. `skipBoth` is also not that great, it can lead to code that works sometimes but fails when the proc is instantiated with branching aliases. This is mostly an issue with error clarity though. --------- Co-authored-by: SirOlaf <unknown> Co-authored-by: SirOlaf <>
* Fix #17509: Continue instead of return with unfinished generics (#22563)SirOlaf2023-09-071-0/+25
| | | | | | | | | | | | | | | | | | | Close #17509 Current knowledge: - delaying cache fixes the issue - changing return of `if inst.len < key.len:` in `searchInstTypes` to `continue` fixes the issue. With return the broken types are also cached over and over Related issues are completely unaffected as of now, so there must be something deeper. I am also still trying to find the true cause, so feel free to ignore for now --------- Co-authored-by: SirOlaf <>
* make getType nodes of generic insts have full inst type (#22655)metagn2023-09-071-0/+35
| | | | | | | | | | | | | fixes #22639 for the third time Nodes generated by `getType` for `tyGenericInst` types, instead of having the original `tyGenericInst` type, will have the type of the last child (due to the `mapTypeToAst` calls which set the type to the given argument). This will cause subsequent `getType` calls to lose information and think it's OK to use the sym of the instantiated type rather than fully expand the generic instantiation. To prevent this, update the type of the node from the `mapTypeToAst` calls to the full generic instantiation type.
* fully revert generic inst sym change, test #22646 (#22653)metagn2023-09-061-35/+0
| | | | | | | reverts #22642, reopens #22639, closes #22646, refs #22650, refs https://github.com/alaviss/union/issues/51, refs #22652 The fallout is too much from #22642, we can come back to it if we can account for all the affected code.
* fix sym of created generic instantiation type (#22642)metagn2023-09-051-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes #22639 A `tyGenericInst` has its last son as the instantiated body of the original generic type. However this type keeps its original `sym` field from the original generic types, which means the sym's type is uninstantiated. This causes problems in the implementation of `getType`, where it uses the `sym` fields of types to represent them in AST, the relevant example for the issue being [here](https://github.com/nim-lang/Nim/blob/d13aab50cf465a7f2edf9c37a4fa30e128892e72/compiler/vmdeps.nim#L191) called from [here](https://github.com/nim-lang/Nim/blob/d13aab50cf465a7f2edf9c37a4fa30e128892e72/compiler/vmdeps.nim#L143). To fix this, create a new symbol from the original symbol for the instantiated body during the creation of `tyGenericInst`s with the appropriate type. Normally `replaceTypeVarsS` would be used for this, but here it seems to cause some recursion issue (immediately gives an error like "cannot instantiate HSlice[T, U]"), so we directly set the symbol's type to the instantiated type. Avoiding recursion means we also cannot use `replaceTypeVarsN` for the symbol AST, and the symbol not having any AST crashes the implementation of `getType` again [here](https://github.com/nim-lang/Nim/blob/d13aab50cf465a7f2edf9c37a4fa30e128892e72/compiler/vmdeps.nim#L167), so the symbol AST is set to the original generic type AST for now which is what it was before anyway. Not sure about this because not sure why the recursion issue is happening, putting it at the end of the proc doesn't help either. Also not sure if the `cl.owner != nil and s.owner != cl.owner` condition from `replaceTypeVarsS` is relevant here. This might also break some code if it depended on the original generic type symbol being given.
