[pacman-dev] [PATCH v2] pacman+libalpm: print version names for conflicting packages

Wed Nov 27 20:40:47 UTC 2019


When ever pacman prints a conflict, it now prints pkgname-version,
instead of just pkgname.

alpm_conflict_t now carries pointers to alpm_pkg_t instead of just the
names of each package.

Fixes FS#12536 (point 2)

v2: dupe each alpm_pkg_t
