[pacman-dev] [PATCH] Add support for whirlpool checksum
by Luke 25 Oct '15

25 Oct '15

Hello, Per bug report #45859, here is a patch to add whirlpool checksum ability to makepkg. This algorithm has been available in Gentoo for some time. It's also very easy to add to our available checksums since it contains only one word to an existing array in makepkg.sh.in. Thanks. Luke

[pacman-dev] [PATCH] add_fileconflict, don't free if CALLOC fail
by Rikard Falkeborn 25 Oct '15

25 Oct '15

If CALLOC fails, conflict is NULL, so we shouldn't attempt to free it's members, since that would lead to a NULL pointer dereference. Signed-off-by: Rikard Falkeborn <rikard.falkeborn(a)gmail.com> --- Is there a reason none of the alpm_*_free() functions check if the input is NULL?
