Re: I'm enhancing GWT to provide Java stack traces for clientside exceptions in production

Hello folks,

I just wanted to remind everyone that the last day to fund this project is this Friday, August 23.

I've been using this framework in production in my app now for 2 months, and it works great.  Have logged 70,000 perfect stack traces so far!  Already fixed 3 major bugs in my GWT-based UI code that I would NEVER found otherwise.

Let's get this capability into GWT by the end of the year.  Please donate!

Thanks,

Alex

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:

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!

Alex
