However I don't know if implementation makes it possible to ignore the context... That's more a question directed to Eliot ;) Nicolas

[Pharo-project] Prune stack serialization

by Martin Dias

Hi folks In Fuel, we serialize a block closure with its state, including its outerContext. This enables to serialize a sorted collection with its sortBlock: | bytes result | bytes := FLSerializer serializeToByteArray: (SortedCollection sortBlock: [:a :b | a > b ]). result := FLMaterializer materializeFromByteArray: bytes. result addAll: #(1 2 3); yourself. ---> a SortedCollection(3 2 1) Here the problem: the byte array is huge! (800kb) because we are serializing unneeded context for the sort block. We wonder how to prune it and save time and space. Thanks in advance MartÃn

[Pharo-project] SubscriptOutOfBounds while Debugging

In Pharo1.4a Latest update: #14238, I keep getting the error while stepping through code. Also, the tools (Browser, Implementors, etc.) take *forever* to appear. Is anyone else experiencing either?

[Pharo-project] Monticello enhancing

by Tobias Pape

Dear all, afte Fuel being available for both Squeak and Pharo, I experimented a little bit. So, I put a new snapshot.fuel beside the snapshot.bin in the mcz zips (same for patch.* in mcd). But to make it easier in the future to experiment with things, I included a small facility to extend serializers/materializers or similar things more easily. How is it done? Example: new serializer in MCZ files: After my patch, include MCMczWriter class>>serializerMine ^ [:writer :snapshot | writer writeSnapshotAsMyFormat: snapshot] and MCMczWriter>>writeSnapshotAsMyFormat: snapshot self addString: (self doSomeConversion: aSnapshot) at: 'snapshot.myformat'. as Extension methods in MCMczWriter, and execute MCMczWriter populateSerializers. Now, a new file member is added to every new mcz file. As an example, I have done such thing for Fuel. Don't worry, it just uses the default behavior if Fuel is not present in either the image or the mcz-file. Best, -Tobias PS: for Squeak, see Inbox Monticello-topa.491, And I also have an MCD attached that should help using the code elsewhere.
