FirebaseExtended
Infinite text looping
Version info
Firebase:
2.3.2
Firepad:
1.3.0
Ace:
1.2.6
Steps to reproduce
I'm not sure how to exactly reproduce this reliably, but it is correlated with calling firepad.dispose() then creating a new firepad with firepad.create()
Actual behavior
The current text in the editor repeats itself multiple times over without terminating.
I get the following error in the web console:
firebase.js:43 Uncaught Error: Both operations have to have the same base length at firepad.TextOperation.TextOperation.transform (firepad.js:757) at Function.firepad.WrappedOperation.WrappedOperation.transform (firepad.js:1935) at transformStack (firepad.js:1993) at UndoManager.firepad.UndoManager.UndoManager.transform (firepad.js:2004) at EditorClient.firepad.EditorClient.EditorClient.applyOperation (firepad.js:2403) at Synchronized.firepad.Client.Synchronized.applyServer (firepad.js:2107) at EditorClient.firepad.Client.Client.applyServer (firepad.js:2070) at operation (firepad.js:2307) at FirebaseAdapter.clazz.trigger (firepad.js:48) at FirebaseAdapter.firepad.FirebaseAdapter.FirebaseAdapter.handlePendingReceivedRevisions_ (firepad.js:1618) firepad.TextOperation.TextOperation.transform @ firepad.js:757 firepad.WrappedOperation.WrappedOperation.transform @ firepad.js:1935 transformStack @ firepad.js:1993 firepad.UndoManager.UndoManager.transform @ firepad.js:2004 firepad.EditorClient.EditorClient.applyOperation @ firepad.js:2403 firepad.Client.Synchronized.applyServer @ firepad.js:2107 firepad.Client.Client.applyServer @ firepad.js:2070 operation @ firepad.js:2307 clazz.trigger @ firepad.js:48 firepad.FirebaseAdapter.FirebaseAdapter.handlePendingReceivedRevisions_ @ firepad.js:1618 (anonymous) @ firepad.js:1551 (anonymous) @ firebase.js:48 Db @ firebase.js:43 zb @ firebase.js:22 Ab @ firebase.js:21 g.Gb @ firebase.js:207 g.Id @ firebase.js:195 yh.Id @ firebase.js:185 (anonymous) @ firebase.js:183 th @ firebase.js:177 ua.onmessage @ firebase.js:176
I also sometimes get this error:
firepad.js:1686 Uncaught Error: sendOperation() called with invalid operation. at assert (firepad.js:1686) at FirebaseAdapter.firepad.FirebaseAdapter.FirebaseAdapter.sendOperation (firepad.js:1443) at EditorClient.firepad.EditorClient.EditorClient.sendOperation (firepad.js:2396) at Synchronized.firepad.Client.Synchronized.applyClient (firepad.js:2100) at EditorClient.firepad.Client.Client.applyClient (firepad.js:2065) at EditorClient.firepad.EditorClient.EditorClient.onChange (firepad.js:2365) at ACEAdapter.change (firepad.js:2288) at ACEAdapter.firepad.ACEAdapter.ACEAdapter.trigger (firepad.js:2682) at ACEAdapter.firepad.ACEAdapter.ACEAdapter.onChange (firepad.js:2475) at Array.<anonymous> (firepad.js:2429)
@Jvlythical Did you find anyway to catch the error and prevent it from causing a mess?
So that error is an internal consistency check that prevents firepad from writing "corrupt" operations into the document history. It's unfortunately not really possible to diagnose without a way to reproduce. Sometimes I've seen it happen after a previous operation has failed (i.e. there's a prior exception that's the real cause), but I assume that's not the case here.
Sorry I can't be more helpful. If you track down repro steps, let me know.
@mikelehen Is there anyway I can catch the error? To prevent it from looping out of control. Like I can have a catch block for the specific error or error group that's thrown and reload the page or something.
Well, I don't understand why it would loop infinitely on its own. I could imagine you'd see it on every key press, but it shouldn't happen uncontrollably AFAIK... So you'd need to debug and figure out why that's happening (sorry).
