Possible memory leak with skin scripts?

[djay]

BUG/PROBLEM REPORT / FEATURE REQUEST

What I did:

I've been trying to track down a memory leak with too many PortletRenders being kept in memory.
They seem to link back to z3c.jbot.patches.registry.
This seems to keep a acquisition wrapped references to the script but for all different weird combinations of the paths that can access that script. The wrapping contains a request. The request contains memoization which contains a lot of stuff including portlet renders.

What I expect to happen:

I'm not sure I understand how jbot is supposed to work with skins but I would have thought it doesn't need to keep the wrapping or the request or even all teh different ways its was accessed.

What actually happened:

What version of Python and Zope/Addons I am using:

this was on plone 5.0 with 0.7.2 z3c.jbot but I increased to 1.1.1 and it still happened.

[djay]

any thoughts on this @jensens ?

[davisagli]

@djay It doesn't look to me like the registry is storing an acquisition-wrapped object (

z3c.jbot/src/z3c/jbot/patches.py

Line 135 in d022ba5

inst = registry[key] = cls.__new__(cls)

) but maybe something that's acquisition wrapped is copied in the next line?

Maybe an IPubEnd handler to delete request.__annotations__ would help

[djay]

@davisagli its the key thats the problem not the value. You can see from the 2 tuple in the objgraph chain. I'm not sure of the implications but as far as I can I understand you don't need the full object for the key?
So I put in an first hack in #18.

Does it really matter the request aquisition path however?
I'm not sure there is even tests for skin script overrides :(

Maybe an IPubEnd handler to delete request.annotations would help

yes also maybe a good idea. Although a request with attached response is not great to hang onto regardless. which package would deleting anotations go? memoize?

[davisagli]

@djay I don't think the acquisition wrapper matters, since the function re-wraps the cached inst before returning it. But you'll have to try it yourself and see what happens, since the package isn't well tested.

[djay]

@davisagli the key has the original wrapped object in it unchanged.

Maybe an IPubEnd handler to delete request.annotations would help

Another way to solve that might be to use a weakref for annotations so it would get naturually be cleaned up. or at least for memoize. since its a cache anyway.

Should you find out that this really makes a difference, then the ``ZPublisher` request's `clear` method should get enhanced. This method is called at the end of request processing and responsible to free all resources held by the request. This should include `__annotations__' (but apparently does not currently).
