We > recently held the Glance Mini-summit and this work was discussed. Andrew > Laski from the Nova team was also in attendance and provided some input > from their perspective. Essentially we decided that while autodiscovery is > desirable, we want to roll that functionality into a much-improved > python-glanceclient which will present a version-agnostic programming api > to users of the library. So the immediate plan is to go back to the > approach outlined in the bp and merge prop you reference above. Then in the > near future produce the new glanceclient followed by updating Nova to use > the new library which will address the concerns of autodiscovery among > other things. > > Timeline-wise, I've been a bit covered up with some other work but will be > getting back to this within a week. There were some concerns about the size > of the patch so rather than unabandoning the existing one I will be trying > to put up multiple, smaller patches. > > Please let me know if you have any specific concerns or requirements so > they can be addressed. > > > Eddie Sheffield > Rackspace Hosting, Inc. > eddie.sheffi...@rackspace.com > > Hi Eddie, thanks for your prompt reply and the information you provided. Could you add me in the review list if you have submmited new patches? Thanks again! -- *---------------------------------------* *Lingxian Kong* Huawei Technologies Co.,LTD.
