Comment 1 Alan Pevec 2012-09-06 08:46:01 UTC
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 20:52:32 UTC

Comment 5 Derek Higgins 2012-09-27 16:51:49 UTC
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 17:42:45 UTC
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.
