python项目通用组件和基础服务

很多公司都大量使用了python，其中有一些开发规范，code guidline， 通用组件，基础框架是可以共用的。

每个公司都自己搞一套, 太浪费人力，我想开一帖和大家讨论一下这些python基础设施的搭建。

原则是我们尽量不重新发明轮子，但开源组件这么多，也要有个挑选的过程和组合使用的过程，在这里讨论一下。

另一方面，有些开源组件虽然强大，但我们不能完全的驾驭它，或只使用其中很少的一部分，我们就可以考虑用python实现一个简单的轮子，可控性更强，最好不要超过300行代码。

# Get the current branch name (not so useful in itself, but used in
# other aliases)
branch-name = "!git rev-parse --abbrev-ref HEAD"
# Push the current branch to the remote "origin", and set it to track

publish = "!git push -u origin $(git branch-name)"

"Russian-Doll Caching" is great. It embraces the Rails (and Ruby) goal to "make the developer happy". And it does. Not having to worry about cache expiration is superb.

It has its limits, though. If you're trying to avoid any database queries, russian-doll caching will not work for you. If you are trying to represent thousands, or even hundreds, of objects under a single cache fragment, russian-doll caching is not the best option.

We use it whenever it makes sense, but sometimes we just have to bite the bullet and expire a cache fragment manually. When you want to start manually expiring cache on a fairly busy website, you have to start considering race conditions. I recently ran into the following scenario:

class Post < ActiveRecord::Base
  after_save :expire_cache

  NumericInput
  PasswordInput
  RangeInput
  StringInput
