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.
Looks good, have at it! There's followup fix (which just caused folsom swift respin) https://review.openstack.org/#/c/13217/1/swift/common/middleware/memcache.py,unified 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?
