Patch that disables Subsonic license checking and validation

README.md

Update 2020 Edition: Use something like Airsonic instead. Subsonic's code is closed source at this point, and thus this patch is useless, unless you are using a 9 year old verison of Subsonic for some reason.

---

A patch to disable the licensing functionality in Subsonic, a GPL-licensed media streaming server/web interface. Use of the mobile apps requires you to get a license after 30 days of trial. You obtain a license via donation.

Except that's not a donation. So, here's a patch to fix that. Support the Subsonic project with a donation that's actually a donation. The program is developed and maintained very well.

Steps to victory

svn co https://subsonic.svn.sourceforge.net/svnroot/subsonic/trunk subsonic

Check out a different branch if you want a specific version.

From the branch root:

patch -p0 < nolicense.patch
mvn install
cd subsonic-booter/
mvn install

Replace the downloaded subsonic.war and subsonic-booter-with-dependencies.jar with the newly compiled ones. Compilation of subsonic-booter is probably optional. It's just a precaution in case the branch you are compiling is newer than whatever version you downloaded.

Also for anyone also finding this Gist from search engines, consider looking at https://github.com/airsonic/airsonic , which is a fork based on the latest open-source subsonic code.

Didn't even realize this was still relevant. In fact, forgot it even existed. I updated the gist again.
