◆ add_conflict()

static int add_conflict	(	alpm_handle_t *	handle,
		alpm_list_t **	baddeps,
		alpm_pkg_t *	pkg1,
		alpm_pkg_t *	pkg2,
		alpm_depend_t *	reason )

static

Adds the pkg1/pkg2 conflict to the baddeps list.

Parameters

handle	the context handle
baddeps	list to add conflict to
pkg1	first package
pkg2	package causing conflict
reason	reason for this conflict

Returns: 0 on success, -1 on error

◆ add_fileconflict()

static alpm_list_t * add_fileconflict	(	alpm_handle_t *	handle,
		alpm_list_t *	conflicts,
		const char *	filestr,
		alpm_pkg_t *	pkg1,
		alpm_pkg_t *	pkg2 )

static

Creates and adds a file conflict to a conflict list.

Parameters

handle	the context handle
conflicts	the list of conflicts to append to
filestr	the conflicting file path
pkg1	package that wishes to install the file
pkg2	package that currently owns the file, or NULL if unowned

Returns: the updated conflict list

◆ check_conflict()

static void check_conflict	(	alpm_handle_t *	handle,
		alpm_list_t *	list1,
		alpm_list_t *	list2,
		alpm_list_t **	baddeps,
		int	order )

static

Check if packages from list1 conflict with packages from list2.

This looks at the conflicts fields of all packages from list1, and sees if they match packages from list2. If a conflict (pkg1, pkg2) is found, it is added to the baddeps list in this order if order >= 0, or reverse order (pkg2,pkg1) otherwise.

Parameters

handle	the context handle
list1	first list of packages
list2	second list of packages
baddeps	list to store conflicts
order	if >= 0 the conflict order is preserved, if < 0 it's reversed

◆ conflict_isin()

static int conflict_isin	(	alpm_conflict_t *	needle,
		alpm_list_t *	haystack )

static

Searches for a conflict in a list.

Parameters

needle	conflict to search for
haystack	list of conflicts to search

Returns: 1 if needle is in haystack, 0 otherwise

◆ conflict_new()

static alpm_conflict_t * conflict_new	(	alpm_pkg_t *	pkg1,
		alpm_pkg_t *	pkg2,
		alpm_depend_t *	reason )

static

Creates a new conflict.
