348039 - Browser freezes during loading of document()

Status: RESOLVED WORKSFORME

(Core :: XSLT, defect)

The XML file uses XSL transformation. I hope the problem is the XSL transformation  tries to open a lot of unexsisting XML documents by using XPath "document()". On some computers, it takes forever to load the XML. However, the worst thing is the browser is complitly frozen in this time. You can't even cancel the operation.

Reproducible: Sometimes

The problem here is that we have to do syncronous loading of documents while in the middle of executing an xpath expression.

Darin: is there any code yet that we could use to keep the UI more responsive while we're spinning the event queue waiting for a document to finish loading? The code we use right now boils down to nsSyncLoader::PushAsyncStream here:

Jonas, have you tested this bug on the trunk?  The thread manager landing should have helped with this bug.

Sergey, can you test if this happens with a recent trunk nightly from here:

I've checked this ine firefox-3.0a1.en-US.win32.installer.exe. It has the same problem. 

I'm not sure that it is XPath document() problem. I've asked other people in the Russian mozilla_ru community on livejournal (http://community.livejournal.com/mozilla_ru/89641.html). Some people have this problem some people don't. Probably, it also depends on resources. For example, my computer has 256Mb RAM only.

If this happens to things other than document() then please attach a testcase

I can get the internet window open, but nothing loads. Then it freezes and makes me close it. I want my firefox back so badly...

alexandrias: did you test with a build from the link in comment 3? What page did you load to test?

[Chris Shoemaker]

There's been no response to comment #7.  Is this still a critical bug? and is it XSLT?

Hello Phil! is this issue still available in the latest firefox version if not can we close it? In my opinion this issue seems to be solved in the latest firefox versions.

When did I become the triage owner for XSLT?
