Please sed the patch and resubmit.
I did it already:
http://chantry.homelinux.org/~xav/gitweb/gitweb.cgi?p=pacman.git;a=shortlog;... Thanks a lot. I found this comment _very_ useful: /* The list pointers passed in should be considered invalid after calling this function. */ This also shows that the tail pointer can confuse us. I have an idea: Since we can check in O(1) time whether a node is a "valid" head node or not (node->prev && node->prev->next == NULL), we could modify alpm_list_last to check this to choose between the new (fast) and the old (slow) algorithms. And modify alpm_list.c to call alpm_list_last whenever last node is needed. By doing this alpm_list.c becomes compatible with the old lists (head->prev == NULL) and we can use sublists (see also: http://www.archlinux.org/pipermail/pacman-dev/2007-November/010213.html) Bye, ngaba ---------------------------------------------------- SZTE Egyetemi Könyvtár - http://www.bibl.u-szeged.hu This mail sent through IMP: http://horde.org/imp/
