Suggested addition to PEP 8 for context managers
by Raymond Hettinger April 19, 2012

April 19, 2012

We should publish some advice on creating content managers. Context managers are a general purpose tool but have a primary use case of creating and releasing resources. This creates an expectation that that is what the context managers are doing unless they explicitly say otherwise.

How closely is tokenize.detect_encoding() supposed to match PyTokenizer_FindEncoding()? From what I can tell, there is a subtle difference in their behavior that has bearing on PEP 263 handling during import. [1] Should any difference be considered a bug, or should I work around it?

Setting up a RHEL6 buildbot
by Nick Coghlan April 18, 2012

April 18, 2012

I'm looking into getting a RHEL6 system set up to add to the buildbot fleet. The info already on the wiki [1] is pretty helpful, but does anyone have any suggestions on appropriate CPU/memory/disk allocations? Cheers, Nick.
