Hello.
In CefGlue now implemented ability to dispose handler objects automatically.
Just now automatically disposed handlers is: CefResourceHandler, CefCookieVisitor, CefSetCookieCallback, CefDeleteCookiesCallback.
This functionality controlled in schema_cef3.py by 'autodispose' member.
Note, that not all handlers should be used with this option, as-is.
For example handler objects returned by CefClient, most of own life time have zero references, and if enable autodispose on them - they will be disposed after first usage.
This is why 'autodispose' should be enabled carefully, with respect to actual API and usage. I'm no have plans to fix exactly this issue, because i'm working on next generation of bindings, and this will be solved somehow.
This should help to How to correctly use VisitUrlCookies?, and similar questions.
All handler objects implement Dispose(bool) method, so it is can be overriden, and it is expected to use. Feel free to report about additional classes which needed to be autodisposed.
