From 911890fbe9d376d59d66eca534769bb5a3b7d935 Mon Sep 17 00:00:00 2001 From: RadhaKrishnan Date: Wed, 23 Jul 2025 19:45:01 +0530 Subject: [PATCH 1/5] fix: normalize tsconfigRootDir to handle trailing path separators in project: true Fixes #11413 When using project: true, the search for tsconfig.json files would stop prematurely if sconfigRootDir contained a trailing path separator. This was due to an incorrect length comparison that included the trailing separator character. The fix normalizes the tsconfigRootDir path and removes trailing separators before comparing lengths, ensuring consistent behavior regardless of whether the path ends with '/' or '\'. Changes: - Modified getProjectConfigFiles to normalize tsconfigRootDir path - Added test case to verify fix works with trailing separators - Maintains backward compatibility with existing functionality --- .../src/parseSettings/getProjectConfigFiles.ts | 2 +- .../tests/lib/getProjectConfigFiles.test.ts | 15 +++++++++++++++ 2 files changed, 16 insertions(+), 1 deletion(-) diff --git a/packages/typescript-estree/src/parseSettings/getProjectConfigFiles.ts b/packages/typescript-estree/src/parseSettings/getProjectConfigFiles.ts index f7f3dc8851b8..ed1d917acce7 100644 --- a/packages/typescript-estree/src/parseSettings/getProjectConfigFiles.ts +++ b/packages/typescript-estree/src/parseSettings/getProjectConfigFiles.ts @@ -57,7 +57,7 @@ export function getProjectConfigFiles( checkedDirectories.push(directory);
