Anton, that was more likely a bug in my save-email routine, which 
I hope is now fixed.

I'm ready for the next round of testing after some bug fixing.
Anyone care to send an email to me at [gchiu-:-compkarori-:-com] ?

Thanks.

incoming

Got mail from didec and ammon.

both classed as spam due to smtp challenge timeouts :(

clearly got to work on that ... my smtp service checks to see if 
the sender has a valid mailbox ...

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 :)

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).

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.

Sure. :) I am helping Graham to find the bugs - I do not demand any 
level of service. :)

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.

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.

Sure, include away ... :)

what are those services, protocols?

ummm... thinking hard ...

popd .. which is a pop server

and smtpd which is a smtp server ( receives mail only so far )

what about your sync protocol? Is that separate one, or part of Uniserve 
architecture?

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

hmm, and how is your sync stuff going? Is it reliable already? :-)

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 :)

you can encrypt streams yourself, no?

yes .. and no

OK, I can test .... I will write also some proposal for new kind 
of app, I think some money can be earned that way :-)

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.

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.

My replication server/client is using View and Uniserve

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?

don't understand the scenario .. are u talking about writing a server 
or client application?

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.

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.
