cygwin-update

This is a simple script for Macs that will update your cygwin mirror using rsync while you are sleeping.

It installs a simple service (via launchd) which downloads the latest setup.exe and runs rsync for the architecture of your choice.

The cygwin.py script makes a number of assumptions, including the following:

• The repository is cloned in to /var/root/src.
• Logging is to /var/root/logs/cygwin.log.
• Update time is 00:10AM.
• Where the files should be saved.
• User and Group for chown after the sync.
• The only architecure to download is x86_64.
• It pre-defines a source rsync mirror.

These assumptions probably do not match with your needs, so you'll need to edit the cygwin.py and org.cygwin.update.plist files to suit.

Choosing A Mirror

There's a script included called mirrors.py to help you in choosing which source mirrors to use. The script will:

1. Download a list of rsync mirrors from cygwin.org.
2. Time the download of a file from each mirror.
3. Print out ordered results with the fastest mirror first.

Install

The script needs to be run as root, so become root before installing.

1. Clone this repository.
2. Edit the cygwin.py and org.cygwin.update.plist files to suit. (See above.)
3. Run the install.py script.

Uninstall

1. Run the uninstall.py script.

Mounting Disks and Running When No-one is Logged In

Mac OS X will, by default, unmount all external disks when there is no user logged in on the console. So, if your syncing to an external disk when logged out the cygwin.py script will fail. The unmounting behaviour can be changed by editting the file /Library/Preferences/SystemConfiguration/autodiskmount.plist to look like the following. A suitable version of this file is included here for your copying pleasure.
