When it comes to actually extracting the new file/symlink, -pacman sees the directory is still there (we do not remove empty -directories if they are owned by a package) and refuses to extract. - -Detect this potential conflict early and bail. Note that it is a -_potential_ conflict and not a guaranteed one as the other package owning -the directory could be updated or removed first which would remove -the conflict. However, pacman currently can not sort package installation -order to ensure this, so this conflict requires manual upgrade ordering. - -Signed-off-by: Allan McRae <allan@archlinux.org> -Signed-off-by: Dan McGee <dan@archlinux.org> ---- - lib/libalpm/conflict.c | 32 ++++++++++++++++++++++++++------ - test/pacman/tests/fileconflict009.py | 20 ++++++++++++++++++++ - test/pacman/tests/fileconflict010.py | 20 ++++++++++++++++++++ - 3 files changed, 66 insertions(+), 6 deletions(-) - create mode 100644 test/pacman/tests/fileconflict009.py - create mode 100644 test/pacman/tests/fileconflict010.py - -diff --git a/lib/libalpm/conflict.c b/lib/libalpm/conflict.c -index 32f6f30..efa1a87 100644 ---- a/lib/libalpm/conflict.c -+++ b/lib/libalpm/conflict.c -@@ -328,15 +328,35 @@ const alpm_file_t *_alpm_filelist_contains(alpm_filelist_t *filelist, - return NULL; - } - --static int dir_belongsto_pkg(const char *root, const char *dirpath, -+static int dir_belongsto_pkg(alpm_handle_t *handle, const char *dirpath, - alpm_pkg_t *pkg) - { -+ alpm_list_t *i; - struct stat sbuf; - char path[PATH_MAX]; - char abspath[PATH_MAX]; -- struct dirent *ent = NULL; - DIR *dir; -+ struct dirent *ent = NULL; -+ const char *root = handle->root; -+ -+ /* TODO: this is an overly strict check but currently pacman will not -+ * overwrite a directory with a file (case 10/11 in add.c).
