Re: [ANN] libosmocore stable API/ABI

Hi all! I think now that the namespace issues in libosmocore have been resolved, we seriously have to think of maintaining a stable API and ABI. This allows us to have truly independent library and application releases, and the dynamic linker library versioning support should ensure compatibility.

So please think twice about any modifying libosmocore. It is safe to add new functions, but we cannot change the prototypes (number of arguments) for existing functions. As soon as new functions are introduced, we should increment the library interface number. For more information, see http://www.gnu.org/software/libtool/manual/libtool.html#Versioning especially the rules in Chapter 7.3: # If the library source code has changed at all since the last update, then increment revision (‘c:r:a’ becomes ‘c:r+1:a’). # If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0. # If any interfaces have been added since the last public release, then increment age. # If any interfaces have been removed or changed since the last public release, then set age to 0.
