Rigorous software design for nano and micro satellites using BIP framework

Marco Pagnamenta

The CubETH satellite mission, a cooperative Swiss CubeSat mission involving ETH Zurich, EPF Lausanne, several universities of applied sciences, and Swiss companies, will allow technology demonstrations and proof-of-concepts concerning GNSS-based navigation ...

Execution Synthesis: A Technique for Automating the Debugging of Software

Cristian Zamfir

Debugging real systems is hard, requires deep knowledge of the target code, and is time-consuming. Bug reports rarely provide sufficient information for debugging, thus forcing developers to turn into detectives searching for an explanation of how the prog ...

Mitigating Anonymity Challenges in Automated Testing and Debugging Systems

George Candea, Silviu Andrica

Modern software often provides automated testing and bug reporting facilities that enable developers to improve the software after release. Alas, this comes at the cost of user anonymity: reported execution traces may identify users. We present a way to mi ...

Querypoint Debugging (Semi-Automated Inspection of Buggy Execution)

Salman Mirghasemi

Debugging is a hard and time-consuming programming task that appears in the most stages of software development and maintenance. Therefore, any improvement in the debugging practice can significantly reduce the time and costs of software production. In thi ...

Striking a New Balance Between Program Instrumentation and Debugging Time

Willy Zwaenepoel, Ricardo Bianchini, Olivier Crameri

Although they are helpful in many cases, state-of-the-art bug reporting systems may impose excessive overhead on users, leak private information, or provide little help to the developer in locating the problem. In this paper, we explore a new approach to b ...

Debug Determinism: The Sweet Spot for Replay-Based Debugging

George Candea, Cristian Zamfir

Deterministic replay tools offer a compelling approach to debugging hard-to-reproduce bugs. Recent work on relaxed-deterministic replay techniques shows that replay debugging with low in-production overhead is possible. However, despite considerable progre ...

Debugging by lastChange

Claude Petitpierre, Salman Mirghasemi

Developers often seek the origins of wrong values they see in their debugger. Their search must be backwards in time: the code causing the wrong value executed before the wrong value appeared. Searching with breakpoint- or log- based debuggers demands pers ...

Querypoint : Moving Backwards on Wrong Values in the Buggy Execution

Claude Petitpierre, Salman Mirghasemi

As developers debug, they often have to seek the origins of wrong values they see in their debugger. This search must be performed backwards in time since the code causing the wrong value is executed before the wrong value appears. Therefore, locating the ...

Debugging real systems is hard, requires deep knowledge of the code, and is time-consuming. Bug reports rarely provide sufficient information, thus forcing developers to turn into detectives searching for an explanation of how the program could have arrive ...

Querypoint Debugging

Claude Petitpierre, Salman Mirghasemi

To fix a bug, software developers have to examine the bug-gy execution to locate defects. They employ different ap-proaches (e.g., setting breakpoints, inserting printing statements in the code) to navigate over buggy execution and inspect program state at ...
