Graham 19-Mar-2005 [159x5] | this is my first crude webmail interface to my smtp service. http://www.compkarori.co.nz:8001/ use userid: "test" password: "account" If you send a message to [test-:-compkarori-:-com], it will take 15mins at least to get thru ( which is the default delay I have built in for mail from new users). But after that it should be very quick. |
And then you will be able to see the message in the webmail interface. | |
I have truncated the message display to the first 5000 chars | |
Anyone like to collaborate on building a decent web interface ? | |
BTW, that is a test to the email account: [test-:-compkarori-:-com] ... and not me :) | |
Anton 20-Mar-2005 [164] | Doc, could you have a look in !webmail group. Graham's cheyenne server is not getting through to me properly (hangs on second read-io of 2048 bytes). |
Dockimbel 21-Mar-2005 [165] | I'll look at it. But remember that Cheyenne's RSP are early alpha and they are still a several issue to solve and bugs to fix before having making them reliable. |
Anton 21-Mar-2005 [166] | Sure. :) I am helping Graham to find the bugs - I do not demand any level of service. :) |
Dockimbel 21-Mar-2005 [167] | The main issue with current RSP is that it includes a session variables synchronization system that's not yet finished. So, the freezing issues should be related to that. This system queues the RSP jobs if it detects that they use the same session variables. (It garanties that your session variable values would not be corrupted by the concurrent execution of RSP). It needs more testing and tuning to be fully reliable. |
Dockimbel 17-May-2005 [168x4] | Just a quick update info about Cheyenne: I'm working on a new version of the RSP module that should fix the previously encountered issues. It needs a lot of testing so it will take a few days before I'll publish anything. |
About UniServe, I'd like to include some protocols/services done by Graham in UniServe's distribution (if he agrees). If anyone has done some protocols or services implementations that would be useful to others, please post some info about them here. I'll be also glad to have from UniServe's users some feedback about UniServe's API, missing features that you would like to be included, etc... | |
To answer a question of MikeL, UniServe is not tied in any way to LNS. | |
In fact, from what I know about LNS, they could be implemented above UniServe using UniServe's service API. | |
Graham 17-May-2005 [172] | Sure, include away ... :) |
Pekr 17-May-2005 [173] | what are those services, protocols? |
Graham 17-May-2005 [174x3] | ummm... thinking hard ... |
popd .. which is a pop server | |
and smtpd which is a smtp server ( receives mail only so far ) | |
Pekr 17-May-2005 [177] | what about your sync protocol? Is that separate one, or part of Uniserve architecture? |
Graham 17-May-2005 [178x3] | That's separate ... |
It was a contracted job that is still not finished ... | |
Anyway, the smtp service is currently being used to process my mail, and it is being picked up by mail clients using the pop service | |
Pekr 17-May-2005 [181] | hmm, and how is your sync stuff going? Is it reliable already? :-) |
Graham 17-May-2005 [182x3] | Well, it works for me .. but that is not adequate amount of testing! |
What I want to see with Uniserve is to be able to encrypt binary data as it is sent | |
Your welcome to test the sync service ... if it works, you won't need to use IOS :) | |
Pekr 17-May-2005 [185] | you can encrypt streams yourself, no? |
Graham 17-May-2005 [186] | yes .. and no |
Pekr 17-May-2005 [187] | OK, I can test .... I will write also some proposal for new kind of app, I think some money can be earned that way :-) |
Graham 17-May-2005 [188x7] | the uniserve client detects that a "packet" is sent by knowing how many bytes are coming ( as in http ), or in knowing at unique end sequence |
as in "." + crlf | |
but when you stream a file that is encrypted, the file length is now changed | |
if you encrypt the whole file at the start, it defeats the point of streaming which is to save cpu | |
the replication server and client are at http://www.compkarori.com/coyote/ | |
I have also a smtp protocol that I will use to send mail. Why not use the existing smtp that comes with Rebol? My one uses Vincent's dig to find the email's mail server, and sends it directly. | |
This bypasses all those problems that some people have with authenticated smtp servers. | |
MikeL 17-May-2005 [195] | From the documentation, "Uniserve's purpose is to offer a simple but powerful solution for programming client and servers applications that can be combined with View interfaces easily." The uses for the Asynch that I can come up with are: 1. Backup after transactions. 2. Journalizing / reporting after a committed transaction update 3. Database access 4. Queuing of side-effect events that are not needed for the response in the user interface. Aside from that, my understanding is that an synch event could be made asynch to allow a lower end server to process the workload. Does anyone have any other uses from the 4 noted? Does anyone have a simple sample of tying Uniserve into the View interfaces? Are there any results of driving some load using uniserve versus synchronous or other solutions like threaded models? I am trying to get my head around this a bit more and want to rely less on the Doc-likes-it-some-it-must-be-the-right-thing-to-do approach that I have used before. I read the Medusa documentation that Doc refers to but it did not lead me to any good application examples. |
Graham 17-May-2005 [196] | My replication server/client is using View and Uniserve |
MikeL 17-May-2005 [197] | Thanks Graham. Your response came in while I was composing this.... OK I have a simple View interface displaying a uniserve response so I follow that. With a view user interface I can see you could get the data needed for multiple tab pages asynchronously and have some saving there. For a script serving out html pages, it could be broken up so that asynch go after independent parts but they would have to be all emitted to the browser at once. Is anyone doing that with Uniserv or other? |
Graham 17-May-2005 [198] | don't understand the scenario .. are u talking about writing a server or client application? |
MikeL 17-May-2005 [199] | In that ramble, I had both - I have a View client app that I want to know how to access Uniservices to make the programming easy and I also want to know how to Uniserve if I want to run a CGI that connects to a database, does some credit application calculations, and emits html to the client. For this CGI script, I would get both performance improvements and an easier programming model ... if I am reading the doc correctly. |
Graham 17-May-2005 [200x3] | Didier is using Uniserve on client side for his forum program - enables async downloading of new messages. Look for ( I think ) lecture-forum.r |
My webmail using Uniserve's http server (Cheyenne) does database connections to retrieve mail http://www.compkarori.co.nz:8001 | |
I have a single odbc connection that is re-used by all the clients so that I do not have the overhead of opening/closing a database connection for each transaction. | |
MikeL 18-May-2005 [203] | Thanks Graham. One like a background refresh of more recently posted messages would be a great example. I looked at Didier's code for lecture-forum. If it uses Uniserve in the version that I located, it is very subtle. I'll ask him if he can illuminate it for me. |
Graham 31-Aug-2005 [204] | Open/skip will be very helpful to allow file resume in Cheyenne. |
Pekr 1-Sep-2005 [205] | you mean open/seek, no? :-) |
Graham 1-Sep-2005 [206] | yeah ... |
Terry 6-Oct-2005 [207x2] | Any simple examples on using "stop-at" with uniserve to pick up posted data??? Can only dig up "GET" ?? |
stop-at binary seems to work, but not stop-at string! | |
