information on Sockets programming appears to be missing from
gnu-smalltalk-doc section 3.8. See below. if anybody knows where the information (UDP and TCP examples) on gnu-smalltalk sockets programming is, please send me a link to it. 3.8 Sockets, WebServer, NetClients ================================== GNU Smalltalk includes an almost complete abstraction of the TCP, UDP and IP protocols. Although based on the standard BSD sockets, this library provides facilities such as buffering and preemptive I/O which a C programmer usually has to implement manually. The distribution includes a few tests (mostly loopback tests that demonstrate both client and server connection), which are class methods in 'Socket'. This code should guide you in the process of creating and using both server and client sockets; after creation, sockets behave practically the same as standard Smalltalk streams, so you should not have particular problems. For more information, refer to **note Network**programming with Sockets*: (gst-libs)Sockets. The library is also used by many other packages, including Swazoo and the MySQL driver. -----Info: (gst)Network support, 26 lines --All----------------------------------------------------- Cannot find node 'Sockets' |

Hi Paolo,
Thank you for the link. Im studying it now. Hmm. Tab complete doesn't work on the socket options I tried implying something is missing from my Smalltalk installation. Is the socket class included in the Ubuntu distribution of Smalltalk 3.2.5? A link to a simple UDP message example would also be much appreciated.

I posted a small TCP (and I suspect UDP) example a while ago, that works for me. Assuming that the old 'legacy' daytime stream server runs on tcp port 13 (as an example). $ gst daytime.st Loading package ObjectDumper Loading package Sockets 'Sat Jun 6 10:30:16 2020' As Derek indicated last june, the key issue is the namespace support. The class below is Sockets.Socket where Sockets. is the package name and Socket the class name: $ cat daytime.st Eval [ PackageLoader fileInPackage: 'Sockets'. s _ Sockets.Socket remote:(Sockets.SocketAddress createLoopbackHost) port:13. (s upTo: Character cr) printNl. s close. ] ----- Op 5 jan 2021 om 20:06 schreef Gary Highberger [hidden email]: > Hi Paolo, > > Thank you for the link. Im studying it now. Hmm.

I'm sorry if this is off-topic, but it seems relevant to GNU smalltalk. In the NEWS file in the 3.2.91 I read "The socket code will be rewritten (for all platforms) for 3.3 anyway." So I'd like to inquire about GNU Smalltalk 3.3 ... or perhaps a 3.2.6 in the 3.2 series ??

For 3.3 I had hoped to solve the deadlock we experienced in the VisualGST debugger with the new event loop. GTK+-2.0 stopped getting maintained and I think we should release 3.3 as is...

I'm not knowledgeable enough but I would be inclined to have a new 3.2.6 version, with as little major changes as possible but still with useful fixes. Basically for me on Solaris, the 3.2.5 and the 3.2.91 work. I've compiled with some GCC versions like gcc 7 and gcc 9 and gcc 10. But I worry about the NEWS file which says that all socket code is going to be rewritten. Obviously I don't want that. I mean, it could be useful to have a new implementation, but at the same time it is important to maintain the old code. So it would be nice if a new 3.2.6 release were to be made. Optionally with also in parallel a new 3.3 release perhaps with more significant changes. Is the current 3.2.91 close to what 3.3 is possibly intented to be ? Or is the current 3.2.91 more like a 3.2.6 release which is still very different from what 3.3 would be ? Anyway I think GNU smalltalk is a nice package, and I'd like to express thanks for all of the work that is being done on it, by the GNU smalltalk team ...

Actually so far I have only just downloaded 3.2.5 and 3.2.91, which is good, I mean it's good that there are package tarballs. But I understand correctly the latest source code is at: http://git.savannah.gnu.org/cgit/smalltalk.git/ There are multiple git branches there, so maintaining the 3.2 branch, while also having a 3.3 branch is a possibility ... |
