Cleaning up old Cruise Control artifacts November 12, 2007

One of the minor issues I have with Cruise Control is that there is currently no easy way to remove old artifacts – they just stay there indefinitely. You will probably not want to keep artifacts around indefinitely, so I wrote a quick script to remove all artifacts except for the most recent X artifacts (where X is configurable).

This will work if you have one root artifacts directory, and then publish artifacts to subdirectories within that directory (i.e., your artifacts dir is /builds and your projects are published to /builds/project-name).

It’s a Python script, and I have a cron job set to run it every ten minutes.

Note: apologies for the formatting, WordPress seems to screw up a bit when copying and pasting in code…

#! /usr/bin/env python

ARTIFACTS_DIR=”changeme”
NUM_BUILDS_TO_KEEP=10

import os

def rm_recursive(path):
“””Removes a directory recursively”””

for root, dirs, files in os.walk(path, topdown=False):
for name in files:
os.remove(os.path.join(root, name))
for name in dirs:
os.rmdir(os.path.join(root, name))
os.rmdir(path)

def delete_old_builds(path):
“””Deletes old builds”””

builds = os.listdir(path)
if len(builds) <= NUM_BUILDS_TO_KEEP: print "No builds to delete" return builds.sort() builds.reverse() i = 0 for build in builds: i += 1 if i <= NUM_BUILDS_TO_KEEP: continue print "Deleting", build rm_recursive(os.path.join(path, build)) for file in os.listdir(ARTIFACTS_DIR): path = os.path.join(ARTIFACTS_DIR, file) if (os.path.isdir(path)): delete_old_builds(path) [/sourcecode]
