From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (WinNT; U) BuildID: 0000000000 When using the XMLExtras component nsDOMParser::ParseFromStream method an assertion is encountered because nsParser attempts to call the ReadSegments method of the supplied input stream, nsFileInputStream, and the method hasn't been implemented yet. Reproducible: Always Steps to Reproduce: 1. Use NS_NewURI to create a new URI for a local XML file (file:///... 2. Use NS_OpenURI to create a channel for the URI 3. Call the channel's OpenInputStream method to obtain an input stream 4. Call the channel's Available method to obtain the amount of data available. 5. Create an instance of a DOMParser (NS_DOMPARSER_CONTRACTID) 6. Call the DOMParser's SetBaseURI with the URI created from step 1. 7. Call the DOMParser's ParseFromStream passing the in the: - Input Stream - "UTF-8" - available data - "text/xml" - an output variable of type nsIDOMDocument 8. The assertion will occur during the call in step 7. Actual Results: nsParser invokes the input streams ReadSegments method, resulting in an assertion because it has not yet been implemented. Expected Results: The XML data is parsed.

Hmm... I do not think Harish is the person to own this bug. Rick Potts? This would also be a good time to think how we do stream peeks...

Giving bug to Rick. CCing myself and Vidur.

updated qa contact.

hey doug, I'm giving this one to you :-) 'cause you're the FileInputStream owner... -- rick

This simple implementation will work as long as the user-define writer function consumes all data. In the examples that I saw in the parser, this is the case. If the writer doesn't consume everything, the implementation will assert. At some point, we should complete this by saving the buffer and offsets. This code was copied out of the jar input stream which I wrote. gagan, can you please r= this? darin, can you please sr= this?

Fix checked in.

Marking verified as per above developer comments.
