This PR solves compatibility issues between Rush and PNPM v10. In PNPM v10, the hashing algorithm for dependency paths was changed to SHA256, and the default
virtual-store-dir-max-lengthwas reduced from 120 to 60 characters. These upstream changes caused Rush-based projects using PNPM v10 to fail during the linking stage, with errors such as:This update enables Rush to correctly support PNPM v10 by updating its dependency on @pnpm/dependency-path and by adjusting logic to account for the new default max-length value.
Fixes #5235
How was the problem solved?
Updated the rush-lib dependencies to include the latest
@pnpm/dependency-pathpackage that uses SHA256 hashing, which is required for PNPM v10.Modified PnpmLinkManager to detect PNPM v10 and use the updated hashing and the new default
virtual-store-dir-max-length(60), while retaining existing logic for PNPM v9 (using 120).The code dynamically imports the correct version of @pnpm/dependency-path based on the detected PNPM major version.
Scope of the solution:
This change fully solves the issue for both PNPM v9 and v10
Backwards compatibility:
This change is backwards compatible. The logic for PNPM v9 is unchanged, and new logic is only applied for PNPM v10 and above.
Performance impact:
No performance regressions are expected; the code path remains similar, only adapting to new PNPM requirements.
Testing
Manual testing was performed on the final commit. I ran the following commands on our production monorepo with both PNPM v10 and PNPM v9 to verify correct behavior and ensure no regressions:
