It fails in TCPSocket class(Socket class)>>echoBytesOn: (as shown in the debugLog in the mail with the debugLog ;-) ).

The point of my changes to those methods was to use 'self initializeNetwork' instead of 'Socket initializeNetwork' (to free up the "Socket" class name :).

Flow 2 alpha 1 released
by Craig Latta 13 Aug '02

13 Aug '02

Hi-- Alrighty then... I just released Flow 2 alpha 1, a streaming framework for Squeak. It provides a handy interface for manipulating external resources of various stripes, and for writing services that use them (e.g., "clients and servers"). Please see http://netjam.org/flow for details. This release features: - greatly simplified installation Download a ZIP file and file-in the sole file within. After installation you're ready to go; you don't need to build a new VM or even restart your running Squeak. I've only tested this with the Squeak 3.2 final snapshot. For the next release, I'll test with subsequent updates loaded. - socket support (not new but worth mentioning :) - filesystem support - partial serial and parallel port support - the basic framework for other planned transports (MIDI, digital audio, IEEE 1394 ["FireWire"], IR) I've tested on GNU/Linux, Windows 98SE, and WinCE. If you'd like to help test on other platforms, please let me know! MacOS X should be particularly straightforward, since it's allegedly FreeBSD underneath (I don't have access to a Mac). There's a Flow mailing list; details are at the website. thanks! -C p.s. As I recall, there used to be a "Squeak announcements" list. It doesn't seem to be around anymore.

one step backward, two steps forward :)

Hi-- Okay, I've finished the testing I can do for Flow 2a... I got positive results for: - Linux 2.4.17, i686 - Windows 98SE - WinCE 3.0.9348.9616 I got negative results for OpenBSD 2.8 and 3.1. I think there's a bug in libc_r and/or the kernel that deadlocks when a child thread make a blocking call to select(). There's a test server running on netjam.org:9007 (a Linux machine). Visit it for a Zen moment. :) I need volunteers to test on other platforms; please let me know if you'd like to help. I'm putting the finishing touches on the release bits. thanks! -C -- Craig Latta improvisational musical informaticist craig(a)netjam.org www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

Integrating NetStreams into the official Squeak release
by Luciano Notarfrancesco 02 Aug '02

02 Aug '02

Any progress? I use Flow everyday, and I'm tired of modifying my projects to use Socket before publishing them. Last weekend started working on a VNC client, and I don't really want to spend time making it work with Socket. I love Flow, and I already said how much I'd like to see it integrated into the official release. But I'll be happy if at least NetStreams make it. Is it possible (and reasonable) to modify the ExternalStreams and ExternalResources in order to load them in an image with the standard Streams? If we can get NetStreams into the 3.3a image, the next step will be removing Socket and refactoring FTPSocket, HTTPSocket and SMTPSocket into FTPClient, HTTPClient, and SMTPClient. What do you think? If you like the idea, I offer my spare time for anything you need to get this done. Peace, Luciano.- ===== http://community.corest.com/~luciano CCB0 B2B0 BCCB 8178 CA8B 4C08 AE9B D2F2 E9CC E897 __________________________________________________ Do You Yahoo!? Yahoo!
