didip / add_to__all__decorator.py

Created January 2, 2013 03:45

Use decorator to avoid retyping function/class names into __all__ module variable. It's an effective way to cut down large number of unnecessary imports caused by "from some_module import *". Works on Python 2.6 and greater.

	import sys

	def add_to__all__(func_or_class):
	""""Use decorator to avoid retyping function/class names into __all__ module level variable."""
	all_list = sys.modules[func_or_class.__module__].__dict__.setdefault('__all__', [])

	if func_or_class.__name__ not in all_list:
	all_list.append(func_or_class.__name__)

	return func_or_class

didip / check-package-versions.py

Created December 21, 2012 05:07

Given requirements.txt file, we can check PyPI for new versions.

	#!/usr/bin/env python

	from __future__ import with_statement
	import os, os.path, sys
	import simplejson as json
	import urllib2
	from distutils.version import StrictVersion

	def pad_spaces(str_, length=18):
	return str_ + ' ' * (length - len(str_))

didip / supervisor-rolling-restart.sh

Created December 13, 2012 16:57

Rolling restart supervisord watched processes. Since every restart it waits for "$status" == "RUNNING", it's safer that simply running /etc/init.d/supervisor restart

	#!/bin/bash

	#
	# Usage: ./supervisor-rolling-restart [supervised-process-name]
	#
	PROGRAM=$1

	# Time in seconds.
	TIME_BETWEEN_RUNNING_CHECKS=0.5
	TIME_BETWEEN_RESTARTS=1
