When the -Sy operation failed, the lock wasn't removed because alpm_trans_release wasn't called. This is fixed now. Also, after my last change in commit 52e7e6d74733f7a431376a9e528c4fe4d3732068 , Sp didn't do anything anymore. That's because needs_transaction returned false for -Sp, so the sync transaction wasn't run. However, the current implementation of -Sp requires a sync transaction. Also, since a transaction creates the lock file at the beginning, and releases it at the end, this mean that -Sp requires root access anyway.. I think I understand now why Aaron found that the current -Sp implementation is hackish :) Signed-off-by: Chantry Xavier <shiningxc@gmail.com> --- src/pacman/sync.c | 3 ++- src/pacman/util.c | 3 +-- 2 files changed, 3 insertions(+), 3 deletions(-)
