Bug 184365 – ASSERTION FAILED: formData in WebCore::ResourceRequest::doUpdateResourceHTTPBody()

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Tools / Tests

[Brendan McLoughlin]

Originally discovered in https://bugs.webkit.org/attachment.cgi?id=337300.


Both of the following tests fail when running `Tools/Scripts/run-webkit-tests` with the
--debug flag. There is no crash when using a release build of
webkit.

imported/w3c/web-platform-tests/fetch/api/redirect/redirect-method-worker.html
imported/w3c/web-platform-tests/fetch/api/redirect/redirect-method.html



The crashes started happening when the `redirect-method` test was
updated in this changeset
https://trac.webkit.org/changeset/230330/webkit#file102 to import
the latest code form the upstream web-platform-test repo.

[Alexey Proskuryakov]

This is a pretty bad logic error. Making delegate calls after creating a stream is wrong.

        // There is no FormData object if a client provided a custom data stream.
        // We shouldn't be looking at http body after client callbacks.
        ASSERT(formData);
        if (formData)
            m_httpBody = formData;
