changeset 11: deefc01c0e14
permissions: -rw-r--r--

Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

 /** Test for Bug 147777 **/
 // Because link-coloring for visited links is asynchronous, running
 // reftests that involve link coloring requires that we poll for the
 // correct result until all links are styled correctly.
 // A requirement of these reftests is that the reference rendering is
 // styled correctly when loaded.  We only poll for the tests.
 var gTests = [
   // there's also an implicit "load visited-page.html" at the start,
   // thanks to the code below.
   // IMPORTANT NOTE: For these tests, the test and reference are not
   // snapshotted in the same way.  The REFERENCE (second file) is
   // assumed to be complete when loaded, but we poll for visited link
   // coloring on the TEST (first file) until the test passes.
