|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8776: fix: fix unnecessary recomputations due to macros r=jonas-schievink a=jonas-schievink This computes a macro's fragment kind eagerly (when the calling file is still available in parsed form) and stores it in the `MacroCallLoc`. This means that during expansion we no longer have to reparse the file containing the macro call, avoiding the unnecessary salsa dependencies (https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349). Marking as draft until I manage to find a test for this problem, since for some reason `typing_inside_a_function_should_not_invalidate_expansions` does not catch this (which might indicate that I misunderstand the problem). I've manually confirmed that this fixes the issue described in https://github.com/rust-analyzer/rust-analyzer/pull/8746#issuecomment-834776349: ``` 7ms - parse_query @ FileId(179) 12ms - SourceBinder::to_module_def 12ms - crate_def_map:wait 5ms - item_tree_query (1 calls) 7ms - ??? ``` Co-authored-by: Jonas Schievink <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | 8280: Borrow text of immutable syntax node r=iDawer a=iDawer In https://github.com/rust-analyzer/rowan/pull/101 `rowan::SyntaxNode::green` returns `Cow<'_, GreenNodeData>`. It returns borrow of green node of immutable syntax tree node. Using this we can return borrowed text from `ast::Name::text`. ~~However now it allocates in case of mutable syntax trees.~~ (see next comment) The idea comes from https://github.com/rust-analyzer/rowan/pull/100#issuecomment-809330325 Co-authored-by: Dawer <[email protected]>
