BUG: fix reading pre-0.14.1 pickles of containers with one block and dup items by immerrr · Pull Request #7794 · pandas-dev/pandas (original) (raw)

Series, frames and panels that contain only one block can be unpickled
under the assumption that block items correspond to manager items 1-to-1
(as pointed out in #7329).

I still don't have any of darwin/win/32bit platforms at hand, so I
cannot post those pickles. Also, my linux has a fresher python than
indicated by filenames of existing pickle test data. I did generate
some data to test the fix, the question is do you want me to upload it?
