// Test for https://github.com/ether/etherpad-lite/issues/1763
|
|
|
|
// This test fails in Opera, IE and Safari
|
|
// Opera fails due to a weird way of handling the order of execution, yet actual performance seems fine
|
|
// Safari fails due the delay being too great yet the actual performance seems fine
|
|
// Firefox might panic that the script is taking too long so will fail
|
|
// IE will fail due to running out of memory as it can't fit 2M chars in memory.
|
|
|
|
// Just FYI Google Docs crashes on large docs whilst trying to Save, it's likely the limitations we are
|
|
// experiencing are more to do with browser limitations than improper implementation.
|
|
// A ueber fix for this would be to have a separate lower cpu priority thread that handles operations that aren't
|
|
// visible to the user.
|
|
|
|
// Adapted from John McLear's original test case.
