Re: ProxyAutoBean server-side cache
Thanks for that reply If the problem is caused by a circular reference , does it mean that the problem disapear whe the reference is a reference to another Entity let's say , I could have Root entity an a Patronyme Entity and Patronyme chained to Root to solve the problem ( or the fix should available soon ? ) Patrick - Original Message - From: Thomas Broyer To: google-web-toolkit@googlegroups.com Cc: b...@google.com ; rj...@google.com ; Julian Scheid Sent: Monday, March 28, 2011 11:52 AM Subject: Re: ProxyAutoBean server-side cache Opened an issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=6193 Will send a patch of the "fixed" WeakMapping soon, after I test it a bit.

Right, that would explain it... I suppose with the Googlers in CC there's no need for me to file a bug report? And while I got you guys on the line, would you mind having a quick look at another recent RF-related post of mine, maybe you missed it at the time I posted it? http://groups.google.com/group/google-web-toolkit/msg/21bc3c893c96f4c6?hl=en -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: ProxyAutoBean server-side cache
[Cc: BobV, rjrjr] That would explain why our test server regularly becomes unresponsive and needs a restart (we shipped our first milestone on Monday for our customer to start testing it; I don't think they complained yet, fortunately; it hadn't beat us earlier as we test on our CI server which is rebuilt and restarted at least once a day) Looking at the code, ProxyAutoBean's createShim creates a reference cycle (the shim references the proxyAutoBean, which keeps a reference on the shim). Because the value in the WeakMapping is kept with a strong reference, there's always a strong reference to key as well, so the cleanup() never has anything to clean. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

ProxyAutoBean server-side cache
Hi, it appears that for every EntityProxy instance that a client requests via RequestFactory, a ProxyAutoBean object is created on the server. Is this correct? If so, what is the lifecycle of the ProxyAutoBean, at what point does it get deleted? I can see (in jvisualvm) that it lives in a WeakMapping, so maybe it is intended to be removed when the GC needs the memory it occupies. However, a few initial tests seem to show that the ProxyAutoBeans survive low memory conditions and keep accumulating. Am I doing something wrong or is this expected behaviour? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
