Alerts

Events such as assertion failures, test failures and fatal signals are likely to be of special interest to developers. Pernosco collects such events into an "alerts" view. When the user starts a Pernosco session, the debugger automatically focuses on the first alert to kickstart the debugging process.

Pernosco enhances the presentation of alerts using application-specific knowledge. For example, Firefox "reftests" fail when two images that should be the same are actually different. In the alerts for those failures, Pernosco shows both images and lets developers examine the differences and click on pixels to trace the data flow leading to a pixel.
