Odd NoneType object has no attribute makefile error #3

Closed stugots closed 11 years ago

The user didn't see any errors, but cloud_browser called cloudfiles which called httplib which got upset. Ever see this before?

Hi John!

Unfortunately, this error doesn't ring a bell. Doing some quick googling, it looks like it is a quirk of httplib2 as it pops up in other wrapping libraries than Rackspace's cloudfiles lib. Here's some basic refs:

The only thing I saw like relating to the python-cloudfiles library was when also using Gevent, which I assume you're not doing: https://github.com/rackspace/python-cloudfiles/issues/65

I do have a Rackspace account, so if you can give me reproduction steps and versions of: cloudfiles and httplib2, I can try it out myself.

If it's just intermittent, you may want to look to upgrading cloudfiles and/or httplib2, if you haven't already done so.

Roger that. Thank you for looking! I'm about to update a bunch of our packages, including cloud files and httplib2. If the gremlin doesn't disappear && persists, I'll delve into the library code.
