Summary [SOUP] URI Fragment is lost after redirect
Paul Ogris
Reported 2017-03-24 10:36:27 PDT
When using webkit_web_view_load_uri with the URI "https://hackage.haskell.org/package/bytestring/docs/Data-ByteString.html#v:map", the jump to the specified anchor is never performed. The page itself redirects to the current version of the documentation hosted there, currently https://hackage.haskell.org/package/bytestring-0.10.8.1/docs/Data-ByteString.html#v:map. Loading this URI directly works as intended. The problem also exists when testing with MiniBrowser. How to reproduce: ./MiniBrowser "https://hackage.haskell.org/package/bytestring/docs/Data-ByteString.html#v:map" Actual Results: The page is displayed, but not at the anchor point specified Expected Results: The page should be scrolled down to the specified anchor. E.g. Firefox preserves the fragment through the redirect. Tested on Fedora 25, the WebkitGtk version used is 2.14.1.

(In reply to Alexey Proskuryakov from comment #1) > > *** This bug has been marked as a duplicate of bug 158420 *** I don't think this is a duplicate of 158420, since 158420 is about a very specific case that occurs on Apple's platforms, whereas this bug is about the original use case mentioned in https://bugs.webkit.org/show_bug.cgi?id=24175 and on non-Apple platforms. WebKit itself makes no effort to preserve these anchors - It relies on the platform networking library beneath it. It seems that the curl networking port doesn't do this correctly.

We use the soup backend, not curl.

Also we're doing additional changes of behaviour here in case of multiple redirections because you are no longer using the first request for several checks.

I copy-pasted it from existing tests, that what I usually do, since I don't know html, css, js :-P > > Source/WebKit2/NetworkProcess/soup/NetworkDataTaskSoup.cpp:107 > > + m_currentRequest = WTFMove(request); > > Not a big fan of adding another element to the internal state of the object. Do you have a better proposal? This is done by NetworkLoad, which could be our client, we could add currentRequest() to the client interface, but I'm not sure it's worth it, TBH. > Also we're doing additional changes of behaviour here in case of multiple > redirections because you are no longer using the first request for several > checks. That's what fixes bug #158420 for us.

As I commented over in https://bugs.webkit.org/show_bug.cgi?id=158420#c8, I'm not sure that *always* applying this behavior is correct. If the investigation in 158420 shows that there's some cases we shouldn't do this, the lib soup implementation should adapt to what we learn.
