Time Travel Debugging Java Applications

A new breed of debuggers let you step and run backwards as well as forwards to see exactly what your code really did.

LOCATION: Online
KEYWORDS: Methods, Tools, Technology

AGENDA:18:00-19:30 h: Talk incl. Q/A

SPEAKER: Greg Law   COMPANY: Undo Ltd
SLIDES: 210324_Greg_Law_Time-Travel_Debugging.pdf
RECORDING: jug.ch YouTube-Channel

Time-travel debugging gives you programming superpowers. Capture a machine-level recording of the execution of a process, load the recording into your IDE to replay and rewind the tape, stepping or running backwards and forwards. Go to any line of code that executed, and see any piece of program state. The most difficult bugs - including race conditions, logic errors, and intermittent exceptions - can be tracked back to their root cause with ease. Perfect for fixing intermittent/non-repeatable test failures in CI ("flaky tests") or hard-to-reproduce failures in production, or collaborating with colleagues remotely and asynchronously. Fix in minutes what would have taken hours, or in hours what would have taken weeks or months.

This talk will cover the new breed of time-travel debuggers. Some are open source, some from the tech giants like Microsoft and some from startups. Having spent decades as a niche research topic, time travel debuggers now have the performance and completeness to be used on real-world, complex tech stacks with millions of lines of code.

Due to the current situation with Covid-19, we are not currently holding many events on site. This event will be broadcast live on the Internet. You do not need to install any software or plugins, everything runs in your web browser. Registered participants will receive a link to the webinar by e-mail shortly before the event.
