We have seen in the previous post how to build an headless xulrunner application.
My first use case was enabling the Mozilla Mccoy application to launch from command line. That allows me to build a bash script which create nightly builds of a firefox extension automatically updated by Firefox every day!.

Here is the resulting Mccoy version :

• Linux i686 patched build of Mccoy: mccoy-0.5-command-line.tar.gz
• Patch based on 0.5 official release: mccoy-0.5-command-line.patch

# Create a new named public/private key
$ ./mccoy -createKey mykey
Creating key with name : mykey
Public key : MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDbV+ZGXs658dOm/+4YtT+VzT5JWzMFYiQ8155fnMkOJCina2yDEBq8Lvi5qF5SyoMDkqaYeO51LR+B4p1g7oWmBW9HbOz3eA9lD/AHUR1SHiJAX7RQq8v9sPSkYta+LyVrCMFgpTmhOWPUXOnwalmL7syGkXyjxHqHCYz+s3d22QIDAQAB
The key has been successfully created!

List all keys in the current mccoy profile
/!\ Don't forget to save your profile!
$ ./mccoy -listKeys
Registered keys :

mykey

Inject the public key in your extension's install.rdf
$ ./mccoy -installRDF myextension_workdir/install.rdf -key myextensionkey
Public key inserted!
Update the signature of the update xml file
$ ./mccoy -signRDF update.xml -key mykey
Sign < update.xml > with key < mykey >
Sign addon : urn:mozilla:extension:mccoy@techno-barje.fr
File signed!
Check if the update xml file is correctly signed
$ ./mccoy -verifyRDF update.xml -key myextensionkey
Check rdf : update.xml with key myextensionkey
Valid signature!
