Comment 1 Alan Pevec 2012-09-06 04:46:01 EDT
I'm not sure this patch is good for stable updates as-is, at least I'd modify it to have memcache_serialization_support=0 as default and add in update description suggested upgrade procedure, from commit message: To avoid an instant full cache flush, existing installations should upgrade with 0, then set to 1 and reload, then after some time (24 hours) set to 2 and reload. Support for 0 and 1 will be removed in future versions.

Created attachment 610623 [details] Default to 0 (pickle) How about this, then - keep the default compatible. The attached patch also adjusts the documentation to point it out.

Comment 4 Alan Pevec 2012-09-18 16:52:32 EDT
There's followup fix (which just caused folsom swift respin) https://review.openstack.org/#/c/13217/1/swift/common/middleware/memcache.py,unified
Comment 5 Derek Higgins 2012-09-27 12:51:49 EDT
Hi Pete, I can't see your patch for some reason (not authorized), do you want me to take a look at it and push into f17? or are you going to make the change?
Comment 6 Pete Zaitcev 2012-09-27 13:42:45 EDT
Derek, if you can do the commit-build-push, it would be a great help. Sorry to make you do it. I marked the attachment public.
