5:33 PM Changeset in webkit [6193] by cblu

• 2 edits in trunk/WebKit

WebKit:

Made web archives use NSPropertyListBinaryFormat_v1_0 instead of NSPropertyListXMLFormat_v1_0 because NSPropertyListBinaryFormat_v1_0 is 3-5 times faster to serialize and parse.

Reviewed by rjw.

• WebView.subproj/WebResource.m: (+[WebResource _parseWebArchive:mainResource:subresources:]): add timing code (+[WebResource _webArchiveWithMainResource:subresources:]): add timing code, use NSPropertyListBinaryFormat_v1_0

WebBrowser:

• BrowserDocument.m: (-[BrowserDocument mailPageAddress:]): call [WebResource _webArchiveWithMainResource:subresources:] and let it handle the property list serialization

WebKit:

• fixed the following bugs: <rdar://problem/3579715>: Going to an error page in back/forward list doesn't work correctly in some cases <rdar://problem/3581031>: REGRESSION (130+): World Leak of WebFrame after trying to load page with unknown scheme

Reviewed by Darin.

• WebView.subproj/WebDataSourcePrivate.h: renamed setRequest -> adoptRequest
• WebView.subproj/WebDataSource.m: (-[WebDataSource _URLForHistory]): updated comment (-[WebDataSource __adoptRequest:]): Renamed from setRequest; now takes an NSMutableURLRequest and uses it as-is. (-[WebDataSource _setRequest:]): now saves a mutable copy, instead of relying on the caller to do so. The (only) caller wasn't doing so in all cases, leading to trouble in River City. Also, special-case unreachable URL handling to allow alternate content to replace a URL in a redirect-like way without sending a redirect callback.

• WebView.subproj/WebFrame.m: (-[WebFrame loadAlternateHTMLString:baseURL:forUnreachableURL:]): renamed after discussion with Richard (was loadPlaceholderHTMLString:baseURL:unreachableURL:) (-[WebFrame _shouldReloadToHandleUnreachableURLFromRequest:]): new helper method, returns YES only if we receive a load request for alternate content from a delegate for an unreachable URL while we are going back or forward. That's a lot of prepositions! (-[WebFrame _loadRequest:subresources:]): if _shouldReloadToHandleUnreachableURLFromRequest: returns YES, change load type to WebFrameLoadTypeReload so b/f list is preserved appropriately. (-[WebFrame _transitionToCommitted:]): Update currentItem in the unreachableURL case. (-[WebFrame _isLoadComplete]): Don't reset b/f list before calling provisionalLoadDidFail delegate; instead, determine where to reset b/f list beforehand, and then actually reset list afterwards only if we didn't start an alternate content load in the delegate. Also, set new boolean ivar so we know when we're processing a provisionalLoadDidFail delegate callback. (-[WebFrame _loadItem:withLoadType:]): don't make extra copy before calling adoptRequest; just pass it the one we made here. (-[WebFrame _checkNavigationPolicyForRequest:dataSource:formState:andCall:withSelector:]): If we're loading alternate content for an unreachableURL, don't ask the decision listener, just do it. (This avoids problem with nested calls to checking the navigation policy that led to a WebFrame leak, and is conceptually the right thing to do also.) Also added some asserts that helped me track down the WebFrame leak. Set new boolean ivar so we know when we're processing a navigation policy delegate decision. (-[WebFrame _currentBackForwardListItemToResetTo]): new method, replaces _resetBackForwardListToCurrent. Does the same test as the latter but returns a boolean rather than actually resetting. (-[WebFrame _continueLoadRequestAfterNavigationPolicy:formState:]): save dataSource in a local var before calling stopLoading, and use it for _setProvisionalDataSource, because otherwise stopLoading was clobbering the dataSource for an unreachable URL handling case.

• WebView.subproj/WebFramePrivate.h: two new boolean ivars

• WebView.subproj/WebView.m: (+[WebView _canHandleRequest:]): return YES when we're loading alternate content for an unreachable URL

WebKit:

First cut at WebKit support for showing error pages for unreachable URLs.

good enough for demos.

This was done in multiple places previously. (-[NSURLRequest _webDataRequestExternalRequest]): now calls _webDataRequestExternalURL to share code (-[NSMutableURLRequest _webDataRequestSetUnreachableURL:]): write new field

• WebView.subproj/WebDataSource.m: (-[WebDataSource unreachableURL]): new method, might become API; returns the unreachable URL, if any, for which this datasource holds placeholder content (-[WebDataSource _URLForHistory]): new method, returns the URL to be stored in History for this dataSource. This returns nil for run-of-the-mill WebDataProtocol URLs (replacing code elsewhere that checked for this case) but returns the unreachableURL for the case where this datasource holds placeholder content. (-[WebDataSource _setTitle:]): now calls _URLForHistory

• WebView.subproj/WebDataSourcePrivate.h: added unreachableURL in the should-become-API section, and _URLForHistory elsewhere

• WebView.subproj/WebFrame.m: (-[WebFrame loadPlaceholderHTMLString:baseURL:unreachableURL:]): new should-become-API method for displaying an error page for an unreachable URL (-[WebFrame loadPropertyList:]): updated to pass nil for unreachableURL (-[WebFrame _webDataRequestForData:MIMEType:textEncodingName:baseURL:unreachableURL:]): added unreachableURL parameter, which gets set on the data request (-[WebFrame _addBackForwardItemClippedAtTarget:]): use _URLForHistory instead of just checking for WebDataProtocol (-[WebFrame _createItem:]): use unreachableURL if there is one (-[WebFrame _transitionToCommitted:]): use _URLForHistory instead of just checking for WebDataProtocol (-[WebFrame _isLoadComplete]): check whether a new load has started in the delegate callback and if so, don't reset the loading state here (-[WebFrame _loadData:MIMEType:textEncodingName:baseURL:unreachableURL:]): added unreachableURL parameter, which gets passed through (-[WebFrame loadData:MIMEType:textEncodingName:baseURL:]): send nil unreachableURL parameter (-[WebFrame _loadHTMLString:baseURL:unreachableURL:]): new bottleneck method for loadHTMLString:baseURL: and loadPlaceholderHTMLString:baseURL:unreachableURL:; this is the guts of loadHTMLString:baseURL: with the new unreachableURL parameter passed through (-[WebFrame loadHTMLString:baseURL:]): now calls new bottleneck method

WebBrowser:

First cut at WebBrowser support for showing error pages for unreachable URLs.
This doesn't work quite right with the back/forward list yet, but is
good enough for demos. The old sheet-using code remains intact, and there's
a menu item in the Debug menu to try the new way (old way is still default
for now).

Reviewed by Darin.

• PreferenceKeys.h: added DebugDisplayErrorsAsPagesPreferenceKey; also deleted a couple of unused old preference keys.

• BrowserWebController.m: (-[BrowserWebView webView:unableToImplementPolicyWithError:frame:]): use showErrorPageForURL:... if the preference is set that way (-[BrowserWebView errorPageHTMLWithTitle:message:]): new method, returns an HTML string for the error page. This will eventually be done reading resources from disk no doubt, but for now we just display a simple page that has the same text as the sheet. (-[BrowserWebView showErrorPageForURL:withTitle:message:]): new method, uses new loadPlaceholderHTMLString:baseURL:unreachableURL: to put up an error page in the webview (-[BrowserWebView expectedOrCurrentURL]): use unreachableURL if there is one

• Debug/DebugUtilities.m: (-[DebugUtilities createDebugMenu]): add menu item "Show Page Load Errors Inline" (-[NSApplication validate_toggleDisplayLoadErrorsAsPages:]): new method, sets the checkmark on the new menu item appropriately (-[NSApplication toggleDisplayLoadErrorsAsPages:]): new method, toggles the state of the preference

• LocationChangeError.m: (-[LocationChangeHandler displayOrRememberLocationChangeError:forDataSource:]): use showErrorPage:... if the preference is set that way

• LocationChangeHandler.m: (-[LocationChangeHandler webView:locationChangeDone:forDataSource:]): use previously-fetched local variable "frame" rather than getting it from the dataSource again. This is not only trivially faster in the normal case, but also avoids a bug when the code earlier in this method triggers another page load (as in the showErrorPage:... case).
