[gwt-contrib] I'm enhancing GWT to provide Java stack traces for clientside exceptions in production
Dear fellow GWT users, I would like to announce that I have finally solved what I always thought to be GWT's greatest weakness: its lack of debugging information for client-side exceptions in production. With my patch, your deployed app will be able to report stack traces like this: com.google.gwt.core.client.JavaScriptException: (TypeError) : a is null com.google.gwt.dom.client.DOMImplMozilla.$getBodyOffsetLeft(DOMImplMozilla.java:145) com.google.gwt.user.client.ui.PopupPanel.$setPopupPosition(Document.java:1287) com.google.gwt.user.client.ui.PopupPanel.setPopupPosition(PopupPanel.java:884) com.google.gwt.user.client.ui.PopupPanel.PopupPanel(PopupPanel.java:453) com.typeracer.commons.client.widgets.EnhancedPopup.EnhancedPopup(EnhancedPopup.java:32) com.typeracer.commons.client.widgets.PopupWithIcon.PopupWithIcon(PopupWithFocusableTextBox.java:28) com.typeracer.main.client.controller.TyperacerUncaughtExceptionHandler$1.execute(TyperacerUncaughtExceptionHandler.java:55) com.google.gwt.core.client.impl.SchedulerImpl.runScheduledTasks(SchedulerImpl.java:50) etc... :-) instead of the current state of affairs that looks like this: lineNumber: 3190 columnNumber: 15354: a is null; (TypeError) fileName: http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html stack: @http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html:2422 Rub@http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html:2423 dSb@http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html:3190 tA@http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html:2810 Xmb@http://localhost:8088/9C4DC2D905BEA407601C92C56B43E3B8.cache.html:2289 etc... :-( I am asking the community to support me in finishing this effort and integrating my patch into GWT. Please take a look and what I've done, and consider making a donation: http://igg.me/at/gwt-stack-traces/x/3494291 I am an indie developer and I just need some funding to continue this work. I'm looking for both grassroots and corporate sponsorship for my quest of improving GWT's error reporting and debugging support. I've written a detailed white paper ( http://goo.gl/YGsrQ ) that describes how my solution works and why it is necessary. I welcome your feedback! Thanks!
