Tmpcleaner

Tmpcleaner is simply advanced temp cleaner with statistical capabilities. It passes given structure only once, groups directories/files by given definition, applies different cleanup rules by each group and print final statistics.

Installation

Tmpcleaner is compatible and tested with Python 2.6.6 and newer.

You can install it with PIP from Pypi:

pip install tmpcleaner

Or directly from Github:

pip install -e 'git://github.com/gooddata/tmpcleaner.git#egg=tmpcleaner'

Or from local GIT checkout:

python setup.py install

Then you can run it by tmpcleaner.py script that is installed within package.

Usage

Let's assume you have /tmp/app directory with some special huge structure, maybe on shared network filesystem where each operation is expensive. Now you want to clean it up and gather some statistics.

Configuration

Configuration file should be simple YAML file.

Global options

Parameter	Description
pidfile	path to PID file, if empty, then PID won't be saved
path	path to pass
pathIgnore	regular expression for path to ignore, eg. '.*/\.snapshot$' to ignore directories named .snapshot

Definition options

Parameter	Description
name	friendly name for classification (otherwise id will be used
pathMatch	regular expression for path to match
pathExclude	regular expression for path to exclude
filesOnly	ignore directories
noRemove	don't remove files/directories, only gather statistics
atime	filter by access time (hour)
mtime	Filter by modification time (hour)
ctime	filter by status change time (hour)

Example

---
pidfile:    /var/run/tmpcleaner.pid
path:       /tmp/app
pathIgnore: '.*/\.snapshot(/.*|$)'

definitions:
	- # Always remove files named test when found
		name: test
		pathMatch: '.*/test$'
	- # Cleanup files that weren't modified for more than 1 day
		name: users
		pathMatch: '/tmp/app/users/.*'
		mtime: 24
	- # Never cleanup project directories, print just statistics
		name: projects
		pathMatch: '/tmp/app/projects/.*'
		noRemove: true

Execution

Execute simply by running

tmpcleaner.py /etc/tmpcleaner.yaml

Output will look like this, sizes are in bytes:

WARNING: Passing /tmp/app
WARNING: Summary: path=/tmp/app definition=temp removed_files=3 removed_dirs=0 removed_size=102400 existing_files=0 existing_dirs=0 existing_size=0

Conclusion

Now you should know how to simply setup and use Tmpcleaner.
