[SqNOS] New release: RTL8139 support, TCP/IP "working", native improvements
by Gerardo Richarte 04 Aug '06

04 Aug '06

Hola Leandro!!! > That's really too bad! Stop working that way and start writing tests. You > will love them! I know. I did some tests some time ago, and I did love them. This time the only idea I have for writing tests for the implementation of the HardwareDevices is to actually write a "DeviceSimulator" for each Device, which acts as the hardware, generating IRQs, virtualizing memory and I/O accesses, and so on... and "me da mucha fiaca" (laziness beats me, kind of). I can only think "but this is pretty much like writing a VMWare!", and then, I can't think anymore :-) I think we will find a way to do tests, at least for some specific parts... Any ideas, are more than welcome! Please, experienced testers, help! :-) gera

Stef dijo: > are you writing tests for SqueakNet? > Because this is a cool project and with tests we could really build > on top of it. > > Hi Stef! The truth is that Luciano is doing all the work in NetSqueak. And yes, he's doing lots of tests (lots and interesting). Let me copy here he's last commit log to http://www.squeaksource.com/Net.html. For every thing he does, he does tests. The last thing he implemented for testing is the RealisticLoopback InternalNetworkDevice. A subclass of Loopback which implements drops, corruption and delays. To test how the stack behaves in this cases. On the other side, for SqueakNOS I'm not writing no tests. I don't really know how to write tests for the HardwareDevices, but the truth is that I have not yet felt the magic of tests, so I'm not pushing it too hard... mea culpa. ok, the commit log for your pleasure: Name: Net-len.13 Author: len Time: 1 August 2006, 2:02:21 pm UUID: dcfbc174-bcdb-4690-8af7-b46ab4704681 Ancestors: Net-len.12 - Implemented delayed ACKs in TCP. - New tests for TCP. - Timers now are working. - Refactored InterfaceConduit/ProtocolStack... the two of them are now one: NetInterface. I don't know yet if this is good enough, but I had to do this change because I needed to start and stop timers (TCP, IP reassembly and ARP timers), and the same object that understands #up and #down (the interface) and manages the process that handles incomming packets seems to be the right object to start and stop timers. All processes that are required for the networking stack are started and stopped sending #up and #down to the network interface.

ODBC Timeout
by Mart-Mari Breedt 04 Aug '06

04 Aug '06

Hi, I am using the ODBC package, ODBC-dgd.10.cs.gz, on 3.8. I was wondering if I have a piece of code like this: [ results := ((self newConnection) query: queryString) results. ] valueWithin: 10 seconds onTimeout: [] What would be the correct statement to use in the timeout block in order to correctly (and safely) cancel the execution of the long running query? Thank you. Kind regards, Mart-Mari

[ENH Request] FFI Wide-character Support
by Ron Teitelbaum 04 Aug '06

04 Aug '06

All, After using FFI for a short time now I would say that it is a very important part of the development platform. There is a lot of power to being able to communicate to external systems. Consider talking to databases, report writers, OS api's . Given that this is an important part of our platform, I think that the lack of wide character support is a real problem for squeak. Without wide character support we loose the capabilities to communicate with systems that use languages that are not supported by Ascii. I personally saw this problem in the Microsoft API where there is a lot of support for wide characters. It appears that my problem is solvable by not supporting non Ascii string names however since we have recently started supporting wide characters I'm asking the community to support wide characters in FFI. I do not feel that I have the expertise or the understanding currently to make this change so if anyone has the skills and time to make the change could you please consider it. Send patches to Andreas(andreas.raab(a)gmx.de). Thank you for your time and consideration, Ron Teitelbaum Mantis Bug # 4379 http://bugs.impara.de/view.php?id=4379
