Explainer https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/CrashReporting/AddStackToCrashReports.md https://github.com/WICG/crash-reporting/issues/12 Specification https://wicg.github.io/crash-reporting Design docs https://docs.google.com/document/d/19DpvHIiYbmB9wgIP0BdI4vOnfVLcAZFmfIAml7SqRQA/edit?usp=sharing Summary This feature captures the JS call stack when a web page becomes unresponsive due to JavaScript code running an infinite loop or other very long computation. This helps developers to identify the cause of the unresponsiveness and fix it more easily. The JS call stack is included in the crash reporting API when the reason is unresponsive.

However, "It is already exposed throughout the web platform (via the `error.stack` getter), and there is already a lot of software, both client- and server-side, which deals with parsing the different browsers' formats." Gecko: No signal (https://github.com/mozilla/standards-positions/issues/1057) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/380) Web developers: No signals Other signals: Security Stack frames from cross-domain scripts that were not loaded with CORS must be omitted. WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Goals for experimentation Reason this experiment is being extended The experiment is being extended due to some unexpected issues that a team faced while onboarding to the trial right away. Additionally, multiple teams have found the feature useful and would benefit from additional experimentation time. Internal teams and external partners have expressed excitement about the call stacks feature and have asked for the trial to be extended. This extension will allow us to achieve a more comprehensive understanding of the experiment's impact and ensure that our conclusions are robust and reliable. Ongoing technical constraints None Debuggability Developers can launch DevTools, go to the "Application" Tab, then in the "Background services" section click on "Reporting API" where they can inspect reports that are queued to be sent. Application --> Reporting API Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests? No This feature is not currently testable on WPT, since triggering it requires crashing the browser.
