These two tests fail on Qt since they have been introduced in r136893 with the following diffs: http://build.webkit.sed.hu/results/x86-64%20Linux%20Qt%20Release/r136894%20(45757)/http/tests/xmlhttprequest/post-blob-content-type-async-diff.txt http://build.webkit.sed.hu/results/x86-64%20Linux%20Qt%20Release/r136894%20(45757)/http/tests/xmlhttprequest/post-blob-content-type-sync-diff.txt The original bug can be found at: https://bugs.webkit.org/show_bug.cgi?id=99983 I will skip these tests on Qt until the problem is solved.
I will take a look at this bug.
Qt networking code adds "application/x-www-form-urlencoded" to request header (qhttpnetworkrequest.cpp:156), if header is empty. According to http://tools.ietf.org/html/rfc2616#section-7.2.1 , it may be empty and receiver could inspect content or extension of the uri to identify content type. In case when media type remains unknown, recipient should treat body as application/octet-stream. XHR spec states that when the blob is sent, mime type of the request is the type of the blob and if mime type of the blob is invalid it could be ignored. Just tested with latest chrome and mozilla, they send empty string for content-type header field. Should I add platform specific test for Qt?
