Yang ): In [changeset:"d9e9a9b3016a05e6153de3803998877f91c6cdf4/ghc" d9e9a9b/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="d9e9a9b3016a05e6153de3803998877f91c6cdf4" Fix #13703 by correctly using munged names in ghc-pkg. Summary: Cabal internal libraries are implemented using a trick, where the 'name' field in ghc-pkg registration file is munged into a new form to keep each internal library looking like a distinct package to ghc-pkg and other tools; e.g. the internal library q from package p is named z-p-z-q. Later, Cabal library got refactored so that we made a closer distinction between these "munged" package names and the true package name of a package. Unfortunately, this is an example of a refactor for clarity in the source code which ends up causing problems downstream, because the point of "munging" the package name was to make it so that ghc-pkg and similar tools transparently used MungedPackageName whereever they previously used PackageName (in preparation for them learning proper syntax for package name + component name). Failing to do this meant that internal libraries from the same package (but with different names) clobber each other. This commit search-replaces most occurrences of PackageName in ghc-pkg and turns them into MungedPackageName. Otherwise there shouldn't be any functional differenes. Signed-off-by: Edward Z.
