From c42b5333f0261daa749306471c294c13dc33968a Mon Sep 17 00:00:00 2001 From: "Maxin B. John" Date: Fri, 29 Jul 2016 11:23:35 +0300 Subject: bitbake: fetch2: fix pickle issues while switching from master to krogoth While switching from master to krogoth build with a common download directory, got a large number of warnings like the one listed below: WARNING: freetype-2.6.3-r0 do_fetch: Couldn't load checksums from donestamp /home/maxin/downloads/freetype-2.6.3.tar.bz2.done: ValueError (msg: unsupported pickle protocol: 4) These warnings are caused by the difference in pickle module implementation in python3(master) and python2(krogoth). Python2 supports 3 different protocols (0, 1, 2) and pickle.HIGHEST_PROTOCOL is 2 where as Python3 supports 5 different protocols (0, 1, 2, 3, 4) and pickle.HIGHEST_PROTOCOL is obviously 4. My suggestion is to use 2 since it is backward compatible with python2 (all the supported distros for krogoth provides python2 which supports pickle protocol version 2) (Bitbake rev: cc67800f279fb211ee3bb4ea7009fdbb82973b02) Signed-off-by: Maxin B.
