The same way thumbails must have the search+preview flavor...do videos need an special flavor in order to be played by engage?

Is that documented somewhere?

Hi Mostolog,

There are (potentially) two issues here: the stack traces, and an issue with the player.

First, the stack traces: these are (very unfortunately) normal.  They indicate that the connection with the client was unexpectedly severed and aren't the result of something we're doing deliberately.  Typically they show up when a user is watching a video and closes the tab prior to the video downloading completely.  They can be silenced with logging configuration if they're bugging you.

Second, the engage issue.  Historically videos have been presenter/delivery and presentation/delivery, but that's not technically required - it's going to depend on which engage players you use and what they're looking for.  This is also, in part, why it's not documented :)

If it is safe to ignore those messages, what would be the classes to silence?

My workflow works again after switching to */delivery. I would have save me a lot of time if this were documented...I'm going to PR on engage playear doc at least.

[most...@gmail.com]

What classes/packages do I have to specify in org.ops4j.pax.logging.cfg in order to silence this errors?

It is safe to silence them or i'll be hiding other potential issues? If so...Is there any way to silence those methods only?

Hi Mostolog & Greg,

This is similar/identical to MH-12197. I believe the following code change in the AuthenticationSuccessHandler can mitigate the additional "IllegalStateException: Committed" error stack dumps.

Replace all "HttpSession session = request.getSession();"

With:
"HttpSession session = request.getSession(false);
if (session) {
…
else {
log DEBUG ("The session has already closed, not applying filter XYZ");
}
"

Ref https://opencast.jira.com/browse/MH-12197

I’ll make a ticket & work on the pull.

Thanks Karen!

Greg, would you please update the source to fix this...I could try, but I'm sure it will take me longer to do it...and even more to do it right :P

[Karen Dolan]

Greg and Mostolog,

When I took a closer look at the path of Mostolog's stack trace, the issue was not at getSession(). It was a similar issue, but at the point where the code tries to change a response header to a 500 after starting a response (static file data copy uses a 200).

I made a pull to add warning logs at the point where the static copy went wrong for Mostolog and catch and shorten the stack trace to the core message at the point where the response change was requested.

Lars is reviewing.

The other getSession() in the code might  cause issues, but not for this specific case.

Yes. Can you describe exactly what is going on at this point in time with the engage media module and the engage player.
Is either of those items open in a browser? Was the browser closed or refreshed at the point of these logs?

yes (browser tab)

Ok, you convinced me that the IllegalStateException server side errors are the result of the server making an futile complaint when a client refuses to accept the response to its request.
The log level should be trace. I’ll make a pull.

Hi,

I guess this is the same issue with 2.3.2 I had reported weeks ago, right?

Hi Dietmar,

> I guess this is the same issue with 2.3.2 I had reported weeks ago, right?

Ah, yes.
The WARN “(Response:315) - Committed before 500 null” will still be in the logs after a client disconnect, because it’s the same confusing log strategy buried in an underlying library.
