Peter Weinberger 3d474c8905 internal/lsp/diff: new diff implementation to replace go-diff ... The new implementation is based on Myers' paper, and is in the package diff/lcs. There is a new option newDiff, that can be set to 'old', 'new', or 'both'. The default is 'both', although that may not be the right choice for a release. See gopls/hooks/diff.go. 'both' runs both the old and new diff algorithm and saves some statistics in a file in os.Tempdir(), When (or if) the new code becomes the default, this logging (and some internal checking) will be removed. The new implementation has internal checking, which currently panics. The code in gopls/hooks/diff.go tries to save an encrypted (for privacy) version of the failing input. The package diff/myers has not been replaced, but it could be.
