Re: [Pharo-dev] [OT] .NET OpenSource

by Alain Rastoul

A bridge is already possible with dotNet without the sources on windows using COM: one can load the clr as a COM object and call COM methods (googling quite a bit should give examples in c++ IIRC, and it works). The pain could be marshalling arguments/returns and may be also with the threading model of pharo (may be calling from another thread here?). I think it is the same with the jvm (examples of loading the jvm as a com object are given in the openoffice or staroffice sdk I think, but don't remember exactly - we did it with a collegue quite some time ago). Smalltalk main feature is simplicity and expressiveness and it's great, but smalltalk world suffers from beeing too apart from others and too closed. This could be a great opening door, interoperability and openness is needed (IMHO). Le 13/11/2014 15:52, phil(a)highoctane.be a Ã©crit : > Time for a bridge...

Re: [Pharo-dev] How to check whether the handle is always valid with NativeBoost ?

by Eliot Miranda

Hi Vincent, one way, used in VisualWorks, is to ensure that only valid handles exist. So very early at startup the system does some allInstances invocations on the classes of handles and invalidates all the handles found. This doesn't fix handles stored as raw integers anywhere, but provided the system is designed to have specific objects for external handles (and I hope it is) this shouldn't happen. Since snapshot is relatively rare and start-up relatively frequent (at least in e.g. a web deployment context), one performance improvement is to do the allInstances before snapshot, and then merely enumerate the collection of handles, rather than use allInstances.

How to check whether the handle is always valid with NativeBoost ?

by Blondeau Vincent

Hi ! I am doing a binding to the R library with NativeBoost. So I create some external objects and apply some functions on them. If the handle to the object is not valid, either the function crashes or gives a bad result. How can I ensure to have a valid pointer at anytime ? I see two solutions: - Either check at any NativeBoost call that the handle is valid (by checking the session id) - Or do a proxy that checks the session and recreate the external object. What do you think ?

Re: [Pharo-dev] [OT] .NET OpenSource

by kilon alios

real great news for Mono people this will be not just a great boost to their code base but also will lift the fear of the Micro$oft Monster that made the adoption a lot more difficult. Unfortunately for Pharo .NET as Java are so far away from its user base. Big Companies, with big budgets and scaling concerns and large teams of developer of course will be very interested into what big frameworks like Java and .NET have to offer. On the other side small teams will depend much more on agility , flexibility and ease of use which are not found in big frameworks. Many have tried to port existing agile languages to those frameworks and they have been very succesful but their userbases has been unwilling to make the jump. Because of course agility far exceed language boundaries and also dominates in libraries, tools and eventually the entire community.
