FWIW, here's the egencache --updatechangelogs related patch-thread starters (from which the links can be followed to the threads) from back in early November, on the portage-dev list. The 4/4 patch in the first thread added --reverse-order, tho as the intro suggests, there was prior discussion, which my quick "changelog" search didn't pick up. IIRC the original discussion was triggered on the gentoo-dev list by... patrick@, and infra/robbat2's replies started there. http://permalink.gmane.org/gmane.linux.gentoo.portage.devel/5899 http://permalink.gmane.org/gmane.linux.gentoo.portage.devel/5934 http://permalink.gmane.org/gmane.linux.gentoo.portage.devel/5964 http://permalink.gmane.org/gmane.linux.gentoo.portage.devel/5989 The last two also mention: https://bugs.gentoo.org/show_bug.cgi?id=565540 (egencache --update-changelog: parallel support, bug still, BTW, status: IN_PROGRESS) OK, here's the original gentoo-dev thread OP by patrick@: http://permalink.gmane.org/gmane.linux.gentoo.devel/98287 And here's the beginning of the "infra response" subthread with infra/ robbat2@'s responses: http://permalink.gmane.org/gmane.linux.gentoo.devel/98337 And... as it happens that first infra response explains the oldest-first, straight from the horse's mouth, as the saying goes. =:^) -- Duncan - List replies preferred.
