// Bug 776129 - If a window w calls window.open, the resultant window should be
|
|
// remote iff w is remote.
|
|
//
|
|
// <iframe mozbrowser> can be default-OOP or default-in-process. But we can
|
|
// override this default by setting remote=true or remote=false on the iframe.
|
|
//
|
|
// This bug arises when we are default-in-process and a OOP iframe calls
|
|
// window.open, or when we're default-OOP and an in-process iframe calls
|
|
// window.open. In either case, if the opened iframe gets the default
|
|
// remotness, it will not match its opener's remoteness, which is bad.
|
|
//
|
|
// Since the name of the test determines the OOP-by-default pref, the "inproc"
|
|
// version of this test opens an OOP frame, and the "oop" version opens an
|
|
// in-process frame. Enjoy. :)

// default, we're going to open an in-process frame.

|
|
// back using alert(). Finally, it calls alert('finish').

// Bug 776129 in particular manifests itself such that the popup frame loads
|
|
// and the tests in file_browserElement_OpenMixedProcess pass, but the
|
|
// content of the frame is invisible. To catch this case, we take a
|
|
// screenshot after we load the content into the popup, and ensure that it's
|
|
// not blank.
