Being that Subversion is a wonderful tool for keeping track of changes in a set of files (well, d’uh), I figured I’d start using it as a backup system for my files.

For which it works quite admirably, thank you very much.

The only thing it’s not quite so good at is dealing with new files, files that have been moved and files that have been deleted. Not without a bit of help, anyway.

The solution to this problem turns out to be to use the pysvn python module (if there’s a perl interface to Subversion, I haven’t found it - then again, I didn’t look for it very hard either and in any event pysvn is made by the same people who make Subversion itself which I guess makes it official).

It took less than an hour from deciding to automate management of my local svn checkout directory to a quick google for a perl or python module to installing pysvn and skimming the manual and finally, the result:

#!/usr/bin/env python
"""
Simple svn script. It automatically adds new files (automatically seems to delete missing ones as well).
Password info unfortunately goes hardcoded into a variable and it leaves auth/ directories all over
the place, but that doesn't bother me
"""

import sys
import os
import time

import pysvn

dirname = '/path/to/checkoutdir'
user = 'yourlogin'
passwd = 'yourpass'

def get_login( realm, username, may_save ):
    return True, user, passwd, 1

client = pysvn.Client(dirname)
client.callback_get_login = get_login
client.update(dirname)
for item in client.status(dirname):
    if(item.text_status == pysvn.wc_status_kind.unversioned):
        client.add(item.path)
        print 'adding', item.path
msg = time.strftime('%Y%m%d')
client.checkin(dirname, msg)
