Bug 191602 – WebKit.ApplicationManifestBasic API test is failing when enabling PSON

• Component: WebKit2
• Status: RESOLVED FIXED

[Chris Dumez]

WebKit.ApplicationManifestBasic API test is failing when enabling PSON:
        /Volumes/Data/WebKit/OpenSource/Tools/TestWebKitAPI/Tests/WebKitCocoa/ApplicationManifest.mm:98
        Value of: [manifest.name isEqualToString:@"A Web Application"]
          Actual: false
        Expected: true
        
        
        /Volumes/Data/WebKit/OpenSource/Tools/TestWebKitAPI/Tests/WebKitCocoa/ApplicationManifest.mm:99
        Value of: [manifest.shortName isEqualToString:@"WebApp"]
          Actual: false
        Expected: true
        
        
        /Volumes/Data/WebKit/OpenSource/Tools/TestWebKitAPI/Tests/WebKitCocoa/ApplicationManifest.mm:100
        Value of: [manifest.applicationDescription isEqualToString:@"Hello."]
          Actual: false
        Expected: true
        
        
        /Volumes/Data/WebKit/OpenSource/Tools/TestWebKitAPI/Tests/WebKitCocoa/ApplicationManifest.mm:101
        Value of: [manifest.startURL isEqual:[NSURL URLWithString:@"http://example.com/app/start"]]
          Actual: false
        Expected: true
        
        
        /Volumes/Data/WebKit/OpenSource/Tools/TestWebKitAPI/Tests/WebKitCocoa/ApplicationManifest.mm:102
        Value of: [manifest.scope isEqual:[NSURL URLWithString:@"http://example.com/app"]]
          Actual: false
        Expected: true


The issue seems to be that we're process swapping when the client does:
    NSString *htmlString = [NSString stringWithFormat:@"<link rel=\"manifest\" href=\"data:text/plain;charset=utf-8;base64,%@\">", [[NSJSONSerialization dataWithJSONObject:manifestObject options:0 error:nil] base64EncodedStringWithOptions:0]];
    [webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:@"http://example.com/app/index"]];

Could be related to substitute data and it getting dropped if the load swaps to a new process.

Since it is uncommon it might be a little better to use std::unique_ptr so we don't have to always use the memory of the whole structure.

We already have a struct.  Couldn't we just add one parameter here?
