Fix occasional build failures with shared GitInfo.cache under parallel builds (#390)#393
Merged
Conversation
…el builds (#390) When using a shared \ (e.g. solution-level obj/) with msbuild /m, multiple projects can race on clearing/writing GitInfo.cache, leading to MSB3491 'file is being used by another process'. - Add ContinueOnError=true to Delete (clear), MakeDir, and WriteLinesToFile for the shared cache (consistent with prior race fixes for IsDirty.cache and read paths). - This makes the write failure non-fatal; one concurrent writer succeeds, values are already computed in-memory for all, and the marker is updated. - Updated changelog. Fixes #390
