41986 - XML loading crashes Mozilla when using Content-Encoding : gzip

Status: VERIFIED INVALID

(Core :: XML, defect, P3)

Description

[Taras Tielkes]

I did some experiments with loading compressed XML with the new data loading 
syntax. Doing this with a 6 June M16 nightly build will result in a crash.

Since I'm not sure my method is legit/correct, here's the setup.

I've compressed an XML file using the gnu gzip tool for Windows.
An ASP page on the server reads in the file, sets the HTTP header "Content-
Encoding:gzip" and writes the contents of the compressed XML file to the result 
stream.

The same method, when applied to a normal HTML page works. Server is IIS4 on 
WinNT4. I have not yet tested IIS5, which has automatic HTTP compression 
available.

Taras, can you add a testcase for this? Does this occur with M17 nightlies, too?

Loading zipped XML data isn't a legal use of the XML document loading 
functionality.  Vidur has code in his tree that removes the content type 
parameter from the load method on the document.  Once that is done, this bug 
becomes invalid.

Nisheeth, I don't know Mozilla's layering, but shouldn't your HTTP layer take 
care of any Content-encoding issues, and provide you (the xml parser) with a 
the actual content.

Anyway, there may be some bugs in the code that I use for gzip encoding now, so 
I'll leave this one closed, and check it out at a later date.

Marking verified invalid per last comments.
