Infinite loop on Amazon.com

[markus1189]

edbrowse runs into an infinite loop on https://amazon.com. is there anything I can do to fix this or help fixing it?

To reproduce, I did the following:

$ edbrowse -v
3.7.7
$ edbrowse
edbrowse ready                                                                                            
nojs = amazon.com                                                                                                     
?                
db4                                                                                                       

?                                                                                                         
b www.amazon.com

And here is the trail of the output, including the loop at the end:

Your use of nojs suggests you are trying to disable javascript, but nojs is a .ebrc directive. Use js to toggle javascript on or off, or js- to turn it off. If you turn it off then there is no infinite loop, however, amazon probably won't work at all without it. If it is on, then obviously there is a bug, and we will look into it. It is rather complicated. amazon does something strange to its window.onload function. Karl Dahlke

Thanks for the heads up!

Sorry for the delay. We have been working on major, one might say seismic, shifts, like switching to a different javascript engine, hopefully in 3.8.0. Somehow, in amongst all that, I believe we fixed the infinite loop issue. For me, amazon home page browses, under duktape js and under quick js, though it is slow to come up, and no clue if one could actually log in or do anything on the site. amazon might be the most complicated website on earth, so I don't know if edbrowse will ever support it. Hope so, some day, as it is a valuable site, particularly during the pandemic, and particularly for the disabled. Karl Dahlke

I understand that, that resolves the issue for me, feel free to close :)

sad, not too long ago, you could buy and pay (with wallet code) on amazon with a noscript/basic (x)html browsers.

The toxic web guys did manage their way into amazon in the end.

Yup. In my dream world edbrowse would be powerful enough to manage amazon, but that is the most complicated site I've ever seen. Karl Dahlke
