If you want some older, more experimental (read: *very* prototypey) apps to play with, feel free to download the April 20, 2004 tarball from Sourceforge (v0.994 -- long before the much cooler and much more bug free repubsub came along): http://sourceforge.net/project/showfiles.php?group_id=66293&package_id=64172 Insert disclaimer about it being old, buggy stuff here. But there are some really interesting little apps lurking in there if you have some time to spend and don't mind poking around. Adam |

Hello: I'm new to mod_pubsub and have taken a brief look at the examples and got the server running on my machine. When I ran the publish.py example, I noticed that there is no actual payload being sent with the message. The output from the JS client confirms that this is the case. I have two questions related to this: 1. Any reason why a message payload isn't being sent? 2. What is the method signature for sending a payload with the message? I was also having trouble getting the RSS streamer client to work locally, as it didn't seem to be streaming. What is the best way to debug mod_pubsub systems? Thanks, Brian -- ==== brian lee dae yung biomimetic art and research mux space . com ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. |

Hello, I don't know if this is the proper forum, but here goes. After upgrading to Repubsub v0.2.7 we benchmarked great speed improvements. Unfortunately, how we used Repubsub causes a memory leak. We've got a test application built to expose the leak, and we need some help getting it fixed. To that end, we would like to hire an individual to help us resolve the bug and get the fix integrated into the next version of Repubsub. Pay would be $50/hr. Please send letter of relevant work experience if interested to jo...@ai....

Hi Joyce, In the old Mod pub sub, when a client subscribed to a topic, it was able to query the mod-pubsub server for all the previous events received and routed to that topic. For example in a mod-pubsub based chat, when you joined, you could get a history of the previous messages exchanged. It says in http://mod-pubsub.org/repubsub/docs/repubsub.html *"Replay* of *events* (messages) in any queue (path) is also supported." I'm just wondering how to enable this with the Javascript client. Thanks Steven >Hi Steven, > > What do you mean by "replay"? And I think at the moment there is no > authentication, although there should be soon. > > Joyce Park |

I've completed the flash_repubsub client and uploaded it to the mod-pubsub.org subversion repository [1]. flash_repubsub is a Flash ActionScript 2.0 interface to the repubsub server. The README [2] provides basic usage information. Note, you may want to grab the latest (rev. 23) pubsub.py [3], as it addresses an issue with the FlashTunnel not sending heartbeats properly. Have fun, Patrick [1] flash_repubsub: http://www.mod-pubsub.org/svn/repubsub/flash_repubsub/ [2] README: http://www.mod-pubsub.org/svn/repubsub/flash_repubsub/README [3] pubsub.py: http://www.mod-pubsub.org/svn/repubsub/kn_server/twisted_pubsub/pubsub.py --- Patrick Thompson |

Hi Rohit,
=20
Sorry, but I'm going to be busy for this week, so I won't get a chance
to look at it. But here are some tips that will get you going:
=20
The reason IsConneced and EnsureConnected always return true is that
ultimately the connector's members delegate to the transport. Since it
is always possible to create a transport in your scenario, it will
always return true. You may want to debug into Transport.cpp,
Transport::Connect() and see that all it is doing is setting up the HTTP
transport.
=20
I never tried subscribing to the same kn_id multiple times. You may want
to debug into Connector::Subscribe to see where it locks up.
=20

Subject: [Mod-pubsub-developer] .Net connector IsConnected does not seem
to work
Hi All,=20
The IsConnected and EnsureConnected calls in the .Net connector
always return true as does the Open call, even if the pubsub server is
not running. This is true even after publish/ subscribe have been
invoked on this connection. Is this a bug or are we supposed to do
something else ?
The other problem is that calling Subscribe, with the same kn_id
as was used in an earlier successful Subscribe call, does not return.
The request status handler also isn't invoked and as far as I can make
out the call doesn't reach the pubsub server as well.

Hi Rohit, did anyone ever answer this question? If not, I believe the answer is no - there isn't a way for the server to only send each message to you exactly once. Its idea of whether it has delivered an event successfully is not the same as your idea of whether you received an event successfully -- and that goes double for the JavaScript client, which can have multiple windows/tabs open. Hope that answers your question, JP --- mod...@li... wrote: > Hi, > Is it possible for the pubsub server to detect that a subscription is > from an earlier client, and then not resend earlier messages.

Hi Rohit,
=20
Sorry in responding to you so late, but I've been away for the holidays.
=20
The answer to your question is that your namespace doesn't have a
reference to the LibKNDotNet namespace. In the Dotnet samples which was
written for VS.NET 2002, relies on the fact that a "using" in the global
scope is inherited in any namespaces in the file. For example in a file
for .NET 1.0,
=20
using namespace LibKNDotNet;
=20
namespace MyNS
{
// has access to LibKNDotNet
}
=20
But in .NET 1.1, this is no longer true. MyNS namespace no longer has
access to LIBKNDotNet. To fix, this, you need to move the using into the
MyNS:
=20
namespace MyNS
{
using namespace LibKNDotNet;
}
=20
That will fix the problem.
=20

Subject: [Mod-pubsub-developer] connection status handler in .Net
connector
Hi,=20
I was trying to implement a connection status handler which
implemented IConnectionStatusHandler, but I get the error that the class
is sealed and cannot be inherited from. Am I missing something? I was
doing this so that the client could subscribe again on reconnection with
server. Normally, if connection with server is lost, normally the client
would just sit around, even if the server comes back up the client does
not realise this.
Another question I have is that regardless of offline queueing
being enabled or not, and items being there in the queue or not,
HasItems() always return true. Why is this ?

Yes. No service thread, but otherwise your conjecture is dead-on. George |

I have a general question about scalability. The FAQ states: "Unlike mod_pubsub, Pushlets can only maintain a few simultaneous connections, and require Java programming." Looking at something like Tomcat, it's easy to see that Pushlets are using a thread per-request, and since the request never returns, each client is tying up one thread. Obviously this isn't a requirement of HTTP, it's just how it happens to be implemented. Normally the server is expected to handle the request quickly and return - then the thread goes back into some pool. My question is: what is mod-pubsub doing differently? Is it working at the socket level then, maintaining a list of open connections per subscription and only writing out to them from some service thread when an event occurs on that subscription? In this case I suppose you're only limited by the number of sockets availble to the OS. Sorry if this is a basic question, but I can't find anywhere that spells this out. Thanks |

Hi, Is it possible for the pubsub server to detect that a subscription is from an earlier client, and then not resend earlier messages. My client does not want a replay of messages it had already received before crashing (without unsubscribing). Is this related to the 'journal' concept ? If so could someone please give an example or something as the documentation is a bit confusing on this point. Thanks and regards, Rohit Khetan. _________________________________________________________________ Glamour, lifestyle, health.
