Methods, systems and computer program products for tracking, encoding and decoding the code-location of runtime events. The system receives an encoded identifier function call as a parameter for a first function included in at least one file in a plurality of files of a source code base. The system returns a compact encoded identifier generated by the encoded identifier function call during compilation of the plurality of files of the source code base. In response to receiving a runtime event's identifier from execution of the source code base, the system decodes the encoded identifier to trace back to a unique location of the first function in the source code base, thereby identifying the filename and line number where the event occurred.
