Dear list,
Webkit's QNRHandler.cpp does not set up
ContentLength and QNetworkRequest::DoNotBufferUploadDataAttribute
and eventually forces QNetworkReplyImpl to buffer up the data;
This is not fine for uploading large files, since eventually systems
it will run out of memory
Here is a small patch that works around it.
I will shortly report a bug at webkit.org
But just wanted to check on the qt list if the changes look good ?
