Re: [Pharo-project] NativeBoost callbacks - status?

by Igor Stasenko

okay, seems like i found why: NBExternalAddress>>ulongAt: zeroBasedOffset put: value "Store unsigned 64-bit integer into memory at (receiver's address + ZERO-based offset) using native byte order. Note, there is no range checking " It should use 32-bit values.. Callback code using ulongAt:put. to store single value at certain address in machine code. Since it stores 64-bit value instead of 32bit, it overrides the instructions which follow, and of course that leads to crash. Trait aliases.. is wrong: #longAt:->#nbInt64AtOffset:. #longAt:put:->#nbInt64AtOffset:put:. #ulongAt:->#nbUInt64AtOffset:. #ulongAt:put:->#nbUInt64AtOffset:put: another reason to get rid of confusion with C types.. -- Best regards, Igor Stasenko.

[Pharo-project] Smalltalkhub

by Nicolas Petton

Hi guys! I was a bit off the last 3 days, I was in Paris with Stef (so romantic :-p) and didn't have much time to follow the thread on Smalltalkhub that much. Just to let you know, I'm working on the next upgrade. In randon order, here's some features that will be part of the upgrade: - Several people reported issues (thanks!), and they will be fixed - As an addition to user centric projects, the concept of team will be introduced - Project owners will be able to decide if a project is - Public (read/write) (users will still have to be authentified to commit) - Read-only - Private - A better search (if I have enough time) - A "real" homepage (again, if I have time) The next iteration on it should be focused on contributing: - One public inbox per project - The ability to "copy" a repo (similar to Github's fork) - Branches? And yes, SH is opensource, people are welcome to contribute. Features are also open, and while some parts are mandatory and required by ESUG, I'm 100% open to ideas and improvements. This is for the community, not me :) Also, SH is still in beta. I will never flush the DB, but you may find bugs and want to keep a backup. The stable version will be hosted by Inria and I will eventually migrate the data on their infrastructure. Cheers, Nico

Re: [Pharo-project] MongoTalk update

by Nicolas Petton

Thanks Norbert! It's cool to know that you like it :) Together with Esteban's work on Voyage, it allows us to do extremely cool stuff with Mongo and Pharo. What I like with Voyage-Mongo + MongoQueries is that objects are persisted without any effort, it just works, and we can query Mongo collections like we would do with Smalltalk collections.
