Re: [Pharo-users] Proxies: Subclassing nil

by ClÃ©ment Bera

Hey Sean, Now to create a proxy you need to subclass ProtoObject and not nil. This was changed years ago to avoid some issues. An example of issue that existed: when you subclass nil, as #doesNotUnderstand: is not implemented by default on your proxy, any proxy created receiving a message would crash the VM if you had not overridded #doesNotUnderstand:. Another example is that when you iterate over memory using #nextObject, if the proxy does not answer it you can end with severe VM crashes. In these examples I am talking about the expected VM behavior and not about bugs. So basically the purpose of ProtoObject was to limit the number of VM crashes when playing with proxies / ProtoObjects, instead having a default behavior for several messages such as #doesNotUnderstand: or nextObject. Note that the IDE support for ProtoObject is limited as ProtoObject API is very restricted so it does not have methods such as #inspect, ... That's also on purpose because Proxies may not implement introspection methods. 2015-03-31 14:53 GMT-07:00 Sean P.

Re: [Pharo-users] [Moose-dev] loading Glamour in Pharo 4

Still in this case the problem seems to be that version 0.1 from ConfigurationOfForum wants to load the development version of Glamour in a Moose 5.0 image, which is not going to work.

I wonder if it was correct that subclassing nil used to be allowed and the proper way to create a proxy, and if so why it was changed... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Proxies-Subclassing-nil-tp4816443p4816502.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
