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.

Here's a current diff for upstream version 4.7 of Subsonic: https://gist.github.com/3767624

I can't get this to work. I've installed subsonic from source in my home dir ~/subsonic, I make a file in this dir called noLicence.patch and run the commands, but I get "Hunk #1 Failed [...]" errors. How can I fix this?

In case anybody is still encountering this Gist on Google, please note that there have been recent changes to licensing code which invalidates this patch entirely. My Fork is the only one I'm aware of that is keeping current with upstream Subsonic and does not add bells+whistles.

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.
