After a full resolution, every convergence override is checked for staleness by resolving each of its collected declared ranges through the registry. The overrides were checked one after another: each override's ranges resolved concurrently, but the next override did not start until the previous one finished. With many overrides and a slow registry the override count landed on the critical path, so `pnpm dedupe` was much slower than on pnpm 11, whose check runs the overrides in parallel. All overrides' range lookups are now in flight at once, matching the TypeScript implementation. The result order is unchanged, so warnings still print in override order. The new test parks every range resolution on a barrier sized to the total range count, so it hangs and times out if the overrides are ever serialized again. Closes pnpm/pnpm#15175
pnpm v12 (pacquet)
The pnpm v12 CLI is implemented in Rust. pacquet is its
in-repository package name; the published CLI and executable are named pnpm.
pnpm v12 is the target for new feature development. The TypeScript pnpm v11
CLI under ../pnpm11/ is maintained for bug fixes. Bugs present in both
versions are fixed in both implementations. Bugs present in only one version
are fixed in that version. New features are not backported to v11.
See CONTRIBUTING.md for development setup, debugging, testing, and benchmarking.
