Wikipedia has an article on:




This is a patrol program for the English Wiktionary.

It must be run from a sysop/admin account.

It requires Python + the Python Wikipedia framework. It also requires Tkinter, which usually comes with Python.

Updated September 2009, re-written version.


copy everything after the source tag to the end of the page, save as in the pywikipedia directory/folder

<source lang="python">

  1. !/usr/bin/python
  2. -*- coding: utf-8 -*-

""" this application patrols the en.wikt

requires some version of the "pywikipedia framework", preferably recent, but need not be updated all the time (;-), most code is within this file

requires Python 2.6

requires Tkinter (which you should have with Python)

in, make sure one line reads:

sysopnames['wiktionary']['en'] = "(your username)"

then run! will exit more cleanly if you only use the "quit" button, rather than closing the window

the "console" (on Windoze) or the command shell you started from will display lots of log messages to tell you what it is doing


Edit page -- open a new tab (or window) in default browser in page edit Show diffs -- open a new tab etc showing diffs for revision Skip user -- skip edits by this user for 24 hours Whitelist -- mark all edits seen by by this user for 24 hours (new or old) Skip -- skip this edit for 72 hours (someone else ought to look at it) Mark -- mark this edit patrolled (;-)

large edits won't fit in the differences boxes, use the "show diffs" button to see more the revision list at the bottom will often tell you if a later editor fixed/reverted a bad edit, which you can then mark

  1. timeout set: a set that elements magically disappear from after a time
  2. [may need to add thread locks]

  1. all active tasks, not in skip list, key is revid

  1. tasks skipped for a few days, values are revids

  1. whitelisted users

whitelist = timeoutset(24 * 3600)

  1. users to skip for a while

skipusers = timeoutset(24 * 3600)

  1. queues: tasks, ready to present, ready to mark

tasq = Queue.PriorityQueue() readyq = Queue.Queue() patrolq = Queue.Queue()

  1. prompt "queue": one task rechecked and ready to display

promptq = Queue.Queue(1)

  1. check a task to see where it should go, used at several steps

  1. recheck task, just before presenting to user
  2. reverted edits don't show as patrolled in the log
  3. and page may be (often is) deleted
  4. so we look for one row in the RC table to tell us if the edit is still there
  1. has to run as a thread or it hangs the UI
  2. takes a task off of the readyq and stuffs it in the prompt "queue" (placeholder for one entry)
  1. note we can't select on rcid (which would be cool, and obvious), so we look for everything
  2. with the exact timestamp
