Occassional posts about VoIP, SIP, WebRTC and Bitcoin.
This post is aimed at anyone thinking about contributing to the sipsorcery code base. The code base is written in C# and heavily utilises Microsoft’s .Net framework. If you’re not familiar with C# or .Net that’s not necessarily a big problem. To contribute there are two main attributes you need:
If you have those two attributes and want to help or are frustrated that a fix you want is not getting done fast enough then read on.
A minimal set of steps to get you to a point where contributiions can be made are:
The following paragraphs go through each step in more detail.
Submitting Code Changes
To contribute is as simple as uploading a patch. To do that you’ll need a codeplex account after which you can upload any sipsorcery code files you modify using the Upload Patch function. When patches get uploaded I, and hopefully in the future other sipsorcery project coordinators, will have a look over the patch and if it’s ok commit it to the source tree.
For regular contributors instead of uploading patches and requiring a coordinator to check and commit a better option is to become a project developer and commit changes directly using Subversion. Before going down that path it’s preferred that you upload a couple of patches so that we can check that you know what you are doing and aren’t going to blow anything major up.
Building the source
To build the source code you’ll need two things:
Once you have an IDE installed and downloaded the source tree the solution file most people will be interested in is in the sipsorcery-core directory and is SIPSorcery-Core.sln. Double clicking on that file should open the solution in your IDE and to build simply press F6. If everything goes according to plan the build will be successful and you will now be ready to start thinking about making changes.
The main thing most people will be interested in fixing or enhancing are dialplan functions. In recognition of that the dialplan functionality was placed into a separate assembly (an assembly is what a library or component is called in the .Net World) called SIPSorcery.AppServer.DialPlan. Within that project a most of the dialplan functions exposed to the sipsorcery Ruby dialplans are contained in DialPlanScriptHelper.cs. If you want to fix something in that class you need to make your change, check the project builds and then upload the file(s) you have changed on the sipsorcery site Upload Patch.
