Web replay functionality allows developers to debug their web applications by exactly recording interactions with a web program, and then replaying the resulting execution at will. A prototype implementation has integration with the Web Inspector, and supports many important web features.<br><br>Most replay-related code will be behind the ENABLE(WEB_REPLAY) flag. It will be off by default until folks feel that the feature is ready for feedback through nightly builds.<br><br>A high-level technical description of the prototype is available in the following paper:<br><a href="http://homes.cs.washington.edu/~mernst/pubs/record-replay-uist2013.pdf">http://homes.cs.washington.edu/~mernst/pubs/record-replay-uist2013.pdf</a><br><br>There’s also short demo video from last year:<br><a href="http://www.youtube.com/watch?v=ugHAzyQ6H00">http://www.youtube.com/watch?v=ugHAzyQ6H00</a><br><br>Some accumulated details are on the prototype's wiki:<br><a href="https://github.com/burg/timelapse/wiki">https://github.com/burg/timelapse/wiki</a><br><br><br><span class="Apple-tab-span" style="white-space:pre"> </span>-Brian</body></html>
