There are many reasons why you might want to contribute to an existing app:
 Documentation for an app will be moving to the git repositories in late 2018/early 2019.
The sections that follow will go through the entire workflow of contributing to a ClearOS app.
If you're even thinking about contributing to an existing app...THANK YOU. If you make a contribution to help improve ClearOS for everyone, well then, it's time to hit the pub!
As is often the case, it's sometimes easiest to follow a real-world example. The remaining sections of this tutorial on contributing to an existing app will follow exactly that.
ClearOS has a subscription engine built into the framework. It allows the developer to build apps around CPU core limits, users counts etc. One example is the licensing of the Kopano Basic - a ClearCenter supported app that integrates Kopano into the ClearOS LDAP/Account directory and provides the Kopano Communication and Collaboration Suite. A usability issue has been reported in support/forums that on occasion, a user who purchases additional user CALs not from the Marketplace but via an interaction with ClearCenter sales. In this case, a user sometimes has to wait up to 30 minutes (the cache timeout) for the additional CAL's to appear.
This is what a user would see if they had used all of their existing CALs, purchased more, but were waiting for the cache to expire:
We could tell them to drop to the command line and run:
To force a check of valid subscriptions and refresh the cached content. Many users, however, are not familiar with CLI. Wouldn't it be nice to add a "Refresh Subsciptions" button that triggered the script above. And so, with this in mind, follow along with the workflow while we make this change.
