Re: [cas-user] RE: [cas-user] CAS 4.1.1 and KryoTranscoder ?

Hi,

Seeing this error: "com.esotericsoftware.kryo.serializers.ObjectField.write(
Lcom/esotericsoftware /kryo/io/Output;Ljava/lang/Object;)V", I would say
that there is a version issue somewhere. What's the version of the Kryo
library in your CAS server?

Thanks.
Best regards,
Jérôme

2015-10-23 Thread Vincent Bonamy 
I'm using kryo-3.0.2.jar and kryo-serializers-0.35.jar

Actuallay this version comes with cas-server-integration-memcached 4.1.1 
(see dependency  hierarchy in attachment).

Thanks,

Re: [cas-user] RE: [cas-user] CAS 4.1.1 and KryoTranscoder ?

2015-10-23 Thread Vincent Bonamy 

Hi Jérôme,


I.

Yes, I clean memcached (restart) when I restart my CAS (on my 
workstation) for testing purposes.


In debug mode, I can see what ticket is not well decoded by Kryo.

I dumped one from memcached here :

vincent@dgs-12-5912:/tmp$ telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
get

!�л����TGT-7-SuxCe4TvaSKxzzpHloAlfqJtFar1L5ziWJwbK1xgAVP5vmzPTb-cas.univ-rouen.fr���̒T


END

So maybe there is an issue with KryoTransacoder and 
LdapAuthenticationHandler on 4.1.1 ?




II.

We updated our CAS production server to CAS 4.1.1 with success here today.
I simply disabled kryoTranscoder in ticketRegisry.xml and there is no 
more errors now.


I must admit however that the cpu load was near 100% again ... I found 
the error cause inspecting java threads. In fact I wrote an horrible 
regular expression as a serviceId in a RegexRegisteredService bean ... :

^https?://([A-Za-z0-9_-]+\.?)*-test\.univ-rouen\.fr(:[0-9-]*)?(/.*)?

I removed it and our CAS 4.1.1 works very well now :-)


Thank you for your help and have a nice WE,
Vincent.

Hi,

Based on the logs you sent me privately, I see a lot of
ClassNotFoundException. I would recommend cleaning the whole cache
(restart memcached) before upgrading the CAS server: old TGT may not be
deserializable by the CAS server v4.1.

Thanks.

Re: [cas-user] RE: [cas-user] CAS 4.1.1 and KryoTranscoder ?

2015-10-23 Thread Vincent Bonamy 
Using jmeter (I modified 
https://github.com/Jasig/cas/blob/v4.1.1/etc/jmeter/tests/simpleCasLoginTest.jmx
 
to add execution parameter so that it works), it seems I can now 
reproduce easily the issue with KryoTranscoder on my dev workstation CAS.

I added a log line to have the stack trace (cf 
MemCacheTicketRegistry.java-error.diff).

Please see attached the catalina.out.

The same jmeter test without KryoTranscoder works well (without any errors).

Thank you,
Vincent.

2015-10-22 Thread Vincent Bonamy 
Actually , I logged in to a non proxied and a proxied app successfully just 
after the cas started.
But because of the cpu charge (we switched on this new CAS for all our users at 
13 o'clock today...), next the cas server couldn't answer anymore quickly ... 
and it crashed.

I didn't have time to check that I could log in all our proxied apps ...
