713473 - Uncaught exception on http://bellard.org/jslinux/

Status: RESOLVED WORKSFORME

(Tech Evangelism Graveyard :: English US, defect)

Description

[ferongr]

Seems to be a recent regression, because the site used to work one or two weeks ago. On the 20111225 official Nightly build it doesn't.

STR:

1. Open console (do it first, since the page steals focus and breaks the shortcut)
2. Go to http://bellard.org/jslinux/
3. Observe console. You should see something like "[00:19:00.114] uncaught exception: [Exception... "A parameter or an operation is not supported by the underlying object" code: "15" nsresult: "0x8053000f (NS_ERROR_DOM_INVALID_ACCESS_ERR)" location: "http://bellard.org/jslinux/cpux86-ta.js Line: 9"

Expected result: Virtualized GNU/Linux boots.

Comment 2

[Boris Zbarsky [:bzbarsky]]

The jslinux code is certainly using responseType....

Since WebKit plans to align on this, we should probably just contact Fabrice and ask him to use async XHR, if he's using sync now.

Comment 3

[Masatoshi Kimura [:emk]]

Yeah, the corresponding WebKit bug has been fixed.

Comment 4

[Jean-Yves Perrier [:teoli]]

I sent an e-mail to Fabrice.

Comment 5

It appears to be working again.
