Context:
Cachememory.removeResource
is executed whenever a resource gets deleted.This method aims to remove the deleted resource from the collections persisted in service cache.
Bug:
Resources that aren't directly related to the deleted resource get removed from the cache as well.
After investigation, we've found out this is caused by the
removeResource
method that loops over all the available collections, and removes one item every time, whether or not the target resource has been found.This seems to be caused by the use of the
splice
method chained withfindIndex
:findIndex
returns -1 when the resource isn't found, andsplice
removes the last item of the array.Resolution:
If
findIndex
returns -1, avoid callingsplice
