Subject: Pass a temporary file name to the package phase in the environment variable PORTAGE_B... 
X-Git-Tag: v2.2_pre1~1381
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1f8e2fe1729c68bbe7b173378ce7c9d7bb14f582;p=portage.git

Pass a temporary file name to the package phase in the environment variable PORTAGE_BINPKG_TMPFILE and move the temporary file into place inside binarytree.inject().  This allows binarytree.inject() to perform the move while holding a lock.
