Auto watch a directory and rebuild the repository when an rpm is added/updated

by Patrick Connelly posted on December 19, 2012

Today I started setting up the repository for people to use to install the Solenopsis rpm. The problem is I want to be able to build the rpm (via Jenkins) and push it to a remote server and automatically have the repo rebuild when it sees an rpm updated or added to the directory.

To do this, I wrote a small python script that can be run and backgrounded. It sends a pushover notification and runs createrepo against the target directory.

import re
import httplib, urllib
from subprocess import call

ROOT_DIR = '/path/to/dir'

wm = pyinotify.WatchManager();
mask = pyinotify.IN_CLOSE_WRITE

def pushover(message):
        conn = httplib.HTTPSConnection("")
        conn.request("POST", "/1/messages.json",
                "token": "TOKEN",
                "user": "USER",
                "message": message,
        }), { "Content-type": "application/x-www-form-urlencoded" })

def gen_repo():
        pushover('rebuilding repo')
        call(["createrepo", ROOT_DIR])

class EventHandler(pyinotify.ProcessEvent):
        def process_IN_CLOSE_WRITE(self, event):
                if event.pathname.endswith('.rpm'):

handler = EventHandler();
notifier = pyinotify.Notifier(wm, handler)
wdd = wm.add_watch(ROOT_DIR, mask, rec=True)
