Redirects are evil, well, some of them. There are mutliple forms of redirects. Redirects caused by http refresh content are ok, because experiments show, with those redirects, the old page contents and their requests will come to STOP completely, before any progress from new refreshed page content is reported. So we can safely treat them as separate page loading transactions. Evil are redirects at the http protocol level, like code 302. If the toplevel documents gets replaced, i.e. redirected with 302, we do not care for the security state of the initial transaction, which has now been redirected, we only care for the new page load. For the implementation of the security UI, we make an assumption, that is hopefully true. Imagine, the received page that was delivered with the 302 redirection answer, also delivered html content. What happens if the parser starts to analyze the content and tries to load contained sub objects? In that case we would see start and stop requests for subdocuments, some for the previous document, some for the new target document. And only those for the new toplevel document may be taken into consideration, when deciding about the security state of the next toplevel document. Because security state is being looked at, when loading stops for (sub)documents, this could cause real confusion, because we have to decide, whether an incoming progress belongs to the new toplevel page, or the previous, already redirected page. Can we simplify here? If a redirect at the http protocol level is seen, can we safely assume, its html content will not be parsed, anylzed, and no embedded objects will get loaded (css, js, images), because the redirect is already happening? If we can assume that, this really simplify things. Because we will never see notification for sub requests that need to get ignored. I would like to make this assumption for now, but please let me (kaie) know if I'm wrong. Excurse: If my assumption is wrong, then we would require more tracking information. We need to keep lists of all pointers to request object that had been seen since the last toplevel start event. If the start for a redirected page is seen, the list of releveant object must be cleared, and only progress for requests which start after it must be analyzed. All other events must be ignored, as they belong to now irrelevant previous top level documents. Frames are also evil. First we need a decision. kaie thinks: Only if the toplevel frame is secure, we should try to display secure lock icons. If some of the inner contents are insecure, we display mixed mode. But if the top level frame is not secure, why indicate a mixed lock icon at all? I think we should always display an open lock icon, if the top level frameset is insecure. That's the way Netscape Communicator behaves, and I think we should do the same. The user will not know which parts are secure and which are not, and any certificate information, displayed in the tooltip or in the "page info" will only be relevant for some subframe(s), and the user will not know which ones, so we shouldn't display it as a general attribute of the displayed page. Why are frames evil? Because the progress for the toplevel frame document is not easily distinguishable from subframes. The same STATE bits are reported. While at first sight, when a new page load happens, the toplevel frameset document has also the STATE_IS_NETWORK bit in it. But this can't really be used. Because in case that document causes a http 302 redirect, the real top level frameset will no longer have that bit. But we need some way to distinguish top level frames from inner frames. I saw that the web progress we get delivered has a reference to the toplevel DOM window. I suggest, we look at all incoming requests. If a request is NOT for the toplevel DOM window, we will always treat it as a subdocument request, regardless of whether the load flags indicate a top level document. */ nsCOMPtr windowForProgress; aWebProgress->GetDOMWindow(getter_AddRefs(windowForProgress)); nsCOMPtr window; PRBool isViewSource; { nsAutoMonitor lock(mMonitor); window = do_QueryReferent(mWindow); NS_ASSERTION(window, "Window has gone away?!"); isViewSource = mIsViewSource; } const PRBool isToplevelProgress = (windowForProgress.get() == window.get()); #ifdef PR_LOGGING if (windowForProgress) { if (isToplevelProgress) { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: progress: for toplevel\n", this)); } else { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: progress: for something else\n", this)); } } else { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: progress: no window known\n", this)); } #endif PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange\n", this)); if (isViewSource) return NS_OK; if (!aRequest) { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange with null request\n", this)); return NS_ERROR_NULL_POINTER; } #ifdef PR_LOGGING if (PR_LOG_TEST(gSecureDocLog, PR_LOG_DEBUG)) { nsXPIDLCString reqname; aRequest->GetName(reqname); PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: %p %p OnStateChange %x %s\n", this, aWebProgress, aRequest, aProgressStateFlags, reqname.get())); } #endif nsCOMPtr securityInfo; nsCOMPtr channel(do_QueryInterface(aRequest)); if (channel) { channel->GetSecurityInfo(getter_AddRefs(securityInfo)); nsCOMPtr uri; channel->GetURI(getter_AddRefs(uri)); if (uri) { PRBool vs; if (NS_SUCCEEDED(uri->SchemeIs("javascript", &vs)) && vs) { // We ignore the progress events for javascript URLs. // If a document loading gets triggered, we will see more events. return NS_OK; } } } PRUint32 loadFlags = 0; aRequest->GetLoadFlags(&loadFlags); #ifdef PR_LOGGING if (aProgressStateFlags & STATE_START && aProgressStateFlags & STATE_IS_REQUEST && isToplevelProgress && loadFlags & nsIChannel::LOAD_DOCUMENT_URI) { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: SOMETHING STARTS FOR TOPMOST DOCUMENT\n", this)); } if (aProgressStateFlags & STATE_STOP && aProgressStateFlags & STATE_IS_REQUEST && isToplevelProgress && loadFlags & nsIChannel::LOAD_DOCUMENT_URI) { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: SOMETHING STOPS FOR TOPMOST DOCUMENT\n", this)); } #endif PRBool isSubDocumentRelevant = PR_TRUE; // We are only interested in requests that load in the browser window... nsCOMPtr httpRequest(do_QueryInterface(aRequest)); if (!httpRequest) { nsCOMPtr fileRequest(do_QueryInterface(aRequest)); if (!fileRequest) { nsCOMPtr wyciwygRequest(do_QueryInterface(aRequest)); if (!wyciwygRequest) { nsCOMPtr ftpRequest(do_QueryInterface(aRequest)); if (!ftpRequest) { PR_LOG(gSecureDocLog, PR_LOG_DEBUG, ("SecureUI:%p: OnStateChange: not relevant for sub content\n", this)); isSubDocumentRelevant = PR_FALSE; } } } } #if defined(DEBUG) nsCString info2; PRUint32 testFlags = loadFlags; if (testFlags & nsIChannel::LOAD_DOCUMENT_URI) { testFlags -= nsIChannel::LOAD_DOCUMENT_URI; info2.Append("LOAD_DOCUMENT_URI "); } if (testFlags & nsIChannel::LOAD_RETARGETED_DOCUMENT_URI) { testFlags -= nsIChannel::LOAD_RETARGETED_DOCUMENT_URI; info2.Append("LOAD_RETARGETED_DOCUMENT_URI "); } if (testFlags & nsIChannel::LOAD_REPLACE) { testFlags -= nsIChannel::LOAD_REPLACE; info2.Append("LOAD_REPLACE "); } const char *_status = NS_SUCCEEDED(aStatus) ?
