Bug 81365 – [WK2] ASSERTION FAILED: m_loadState == LoadStateProvisional when receiving multipart/x-mixed-replace data

• Status: NEW
• Component: WebKit2

[Jessie Berlin]

void WebFrameProxy::didCommitLoad(const String& contentType, const PlatformCertificateInfo& certificateInfo)
{
    ASSERT(m_loadState == LoadStateProvisional);
    m_loadState = LoadStateCommitted;
    m_url = m_provisionalURL;
    m_provisionalURL = String();
    m_title = String();
    m_MIMEType = contentType;
    m_isFrameSet = false;
    m_certificateInfo = WebCertificateInfo::create(certificateInfo);
}

Note: NRWT is probably not associating the correct tests with these "crashes" (see https://bugs.webkit.org/show_bug.cgi?id=71380). I have run into this locally as well, but have not been able to figure out which tests it is happening for.

[Radar WebKit Bug Importer]

<rdar://problem/11063711>

[Alexey Proskuryakov]

Can reproduce with http/tests/multipart/load-last-non-html-frame.php in both run-webkit-tests and Safari.

The issue here is that WebKit 2 doesn't implement FrameLoaderClient::revertToProvisionalState at all.

[Alexey Proskuryakov]

Skipped in http://trac.webkit.org/changeset/111201

It's just something that needs to be properly implemented in WK2. Another test affected by this was already in WK2 skipped list, http/tests/multipart/multipart-wait-before-boundary.html.

[Alexey Proskuryakov]

FrameLoaderClient::revertToProvisionalState is still not implemented, and the assertion is still present (it is now in FrameLoadState::didCommitLoad()), but somehow, it doesn't seem to be hit on the tests.
