pytz-memcache

latest version at https://github.com/HatsuneMiku/pytz-memcache

pytz with memcache modified to be high performance that also works on GAE

( copied from pytz-2014.4 )

Usage

• copy zoneinfo.zip to your application directory (current directory on GAE)
• copy pytz-2014.4-gae-py2.X.egg to your application directory

import os

if 'SERVER_SOFTWARE' in os.environ.keys(): # on GAE
  from google.appengine.api import memcache
  from google.appengine.ext import webapp
  # use zoneinfo.zip on current directory
  # pytz-2014.4-py2.5.egg does not work on GAE (pytz.common_timezones is [])
  sys.path.append('pytz-2014.4-gae-py2.5.egg')
else:
  import memcache

import pytz

class GAEHandler(webapp.RequestHandler):
  def get(self, param):
    self.response.out.write(pytz.common_timezones)

Remarks

• 'zoneinfo.zip' must be in your application directory
• memcached must be running on '127.0.0.1:11211' (for local test only)
• (memcached has been running on GAE)
• it takes about few seconds to run at the first time, but faster next
• (it takes very long time when memcahced is not running because worst case)
• please delete key 'pytz_loaded' from cache when update pytz zoneinfo

Do It Yourself

• unzip pytz-2014.4-py2.X.egg
• delete *.pyc
• zip recursive pytz/zoneinfo/ to zoneinfo.zip
• copy zoneinfo.zip to your application directory (current directory on GAE)
• replace init.py open_resource function (in this repository)
• zip pytz/ to pytz-2014.4-gae-py2.X.egg (without zoneinfo.zip)
• copy pytz-2014.4-gae-py2.X.egg to your application directory
