[!Cheyenne] Discussions about the Cheyenne Web Server

The yellow tooltip message when mouse is over the systray icon could 
be a good place. Instead of "Cheyenne is running" could be "Cheyenne 
is listening on port(s) ...". I'll think about it.

Actually I am using your encapped binary and not mine as the localhost 
server doens't need odbc :)  I take your point though.
My server app ( with the binary in the browser ) is now able to prefill 
pdfs, and then when submitted back to the server, able to display 
previously filled in pdfs :)

I think "cheyenne is listening on port " would be good because I 
run a number of cheyenne instances launched by different apps, so 
I can't tell which one is which unless I see the port information.
hhmm.. I'm getting this

7-Mar-2009/21:17:18+13:00 : make object! [

I start up one instance of Cheyenne on port 8000 which is okay, and 
then I start another instance running in port 7999.  The one I connect 
to 2nd produces the crash log.
I am running two instances because the web app uses the same database 
name
Reproduced it on a different pc.
that line comes from task-handler.r

are these ports fixed and so I can only have one instance of cheyenne 
running?

Multiple running instances :


1 ) Cheyenne uses a port translation method for task-master to avoid 
clashing between Cheyenne's instances. This translation is currently 
triggered by the -p command line option specifying on which port(s) 
Cheyenne should listen. So the 'listen keyword in config file doesn't 
trigger the translation. After a quick look, it should be fixable.


2) Logger and RConsole services ports are not translated. This should 
be fixed too.


3) As a consequence of 1) & 2), Cheyenne can't currently run multiple 
instances on the same machine.


I am running two instances because the web app uses the same database 
name
 :


4) I very well aware of this issue and I intend to find a solution 
asap.

OpenSCManager failed : Access is denied
 :


5) I should load that routine! only if trying to run as a Windows 
Service without having admin rights.
I'm looking for 4) first because it's the quickest and cleaner way 
to solve your issues.

What if I use different names for the database, and then alias them 
in the webapp init ?  Then could i just run the one Cheyenne?
no .. that won't work.

I don't understand what's the problem with database names?
Graham

My webapp uses 'emr for the database name.
for one user emr points to one database, but for another user it 
points to a different database
So, to use a single instance of cheyenne, I have to go thru all my 
source and change the database name so that it's different each time 
I want to run more than one instance of this web app
I guess I could use remark for that.

You've set up one database per user?
I'm working on the support of per webapp databases definition instead 
of being global. So you could have a 'emr database definition different 
for each webapp (while keeping the same name in sources).

I have a demo database that contains dummy data ... anyone can access 
it.
I have a real database which I don't let anyone except myself access 
:)
so one set of users access the demo website, and I use the other 
one.

I see, so the patch I'm working on should solve that. It should be 
available tomorrow.

Graham, I have a working patch that supports setting same DB virtual 
name to different connections URL per webapps. Here's an example 
definition of 2 webapps using this new feature :

	webapp [
		virtual-root "/curecode1/"
		root-dir %//dev/curecode/
		locales-dir %private/locales/
		
		databases [
			bugs	mysql://[root-:-localhost]/bugs1
		]
	]
	webapp [
		virtual-root "/curecode2/"
		root-dir %//dev/curecode/
		locales-dir %private/locales/

		databases [
			bugs	mysql://[root-:-localhost]/bugs2
		]
	]
So, in order to reuse the same code for your EMR app but branching 
on 2 disctinct databases, you'll have to define 2 different webapps.
I've also patched the systray code to include the port number(s) 
in the yellow help message.
Patch available here : http://cheyenne-server.org/tmp/patch-0920.zip
Just replace the patched file in your current Cheyenne v0.9.19 sources 
folder.
Test this very carefully before taking it in production and report 
me any issue/bugs related to that patch (be sure to have checked 
your own code before reporting).
Btw, the 'databases keyword in global section is still working but 
the 'databases definition block in webapp will take precedence if 
provided.

what's the process of acccessing a rsp page ?
is this all I need ?

	session/start
    	session/content/login?: yes
and I need an app-init.r in the web-app directory?
Looks like it won't work without an app-init.r

An RSP page can be accessed standalone without a webapp. The webapp 
gives  you some additional features like automatic session starting, 
optional authentification protection, private folders, app-init events, 
etc...
Graham

I tried that .. and got no response

See the RSP script examples provided in %www folder from Cheyenne 
sources.
I don't understand what you want to achieve with the code above?

access the web app folder
I couldn't get rsp working in www/ directory

What's your webapp folder?

no ..
let me try this again.
gee, rsp is now working again in the www/ directory.
