Streaming unreliable on Opera in 1.0.12

[ghost]

Streaming will sometimes deliver incorrect messages on Opera 12. Seems to me that the special case for Opera when streaming does not use _trackMessageSize at all, which would explain the problems.

Have you try 1.0.13-SNAPSHOT by any chance?

Tried also with 1.0.13-SNAPSHOT javascript - still reproducible. It is not the same issue as #1027. The issue can be seen here: http://artur.virtuallypreinstalled.com/TablePush/?debug

Heavily tested using [this][(https://gist.github.com/jfarcand/5374686). Let me know how it goes.

Awesome work. With the fixed version I no longer see any issues in my test.

[Legioth]

Still seeing problems with this. It seems like the connection is always reconnected after calling push from the client.

@Legoth: Share a test case, as I can't reproduce this issue. Are you using streaming or ling-polling?

Is there something in the fix that potentially cause severe regressions in streaming in at least IE10 and Opera 12? Testing with the lastest 1.0.13-SNAPSHOT js (1.0.12 server side) I see messages received multiple times on the server and possibly on the client also.

Downgrading to 1.0.12 fixes the issue. It's so bad that IE10 will crash after a few minutes of pushing back and forth at full speed.

@artur: You said you tested above and nothing changed since then. So are you saying both opera and IE 10 are broken? Will take a look soon.

[jfarcand]

Also, can you share your test case? I've tested with the gist above (simulate cache etc.) and it worked....

I think how I tested previously above did not show this regression.

The issue can be seen at http://artur.virtuallypreinstalled.com/PingPong/?transport=streaming&minsize=1000&maxsize=1000&symmetric=false&update=true&duration=1&go

in Chrome/Firefox this counts up 1,2,3... as expected
In Opera and IE10 there are duplicates every now and then.

http://artur.virtuallypreinstalled.com/PingPong-old/?transport=streaming&minsize=1000&maxsize=1000&symmetric=false&update=true&duration=1&go is identical to the test above except with an older js. In IE 10 (also in IE 9 mode) there is a huge difference as the newer one produces around 2 roundtrips per second with duplicates especially in IE10 mode whereas the old one produces > 40 roundtrips per second.
