Upstream Tracker

Jump to: navigation, search

Linux Upstream Tracker is a service for automatic monitoring and analyzing of API/ABI changes in C/C++ libraries. The service checks new releases of libraries for unintentional API/ABI breaks and critical run-time errors. It is intended for Linux maintainers to help in updating libraries and for software developers who are interested in ensuring backward compatibility.

The service is based on the ABI Compliance Checker (tracking API/ABI changes), API Sanity Checker (automatic run-time unit testing) and PkgDiff (tracking changes in source code) tools.

Note: The service was closed on 21 July 2015. Please use the ABI Tracker project instead.


The tool was originally developed by Andrey Ponomarenko at ISPRAS and later it was developed and supported by NTC IT ROSA in Russia.
