1: Figuring out location without a connnection
Posted by Janine Ohmer on 04/11/02 08:30 PM
I have a bad feeling that this a stupid question, that the answer is
obvious, but I can't seem to figure it out so here goes:

I have two sites, staging and live, which share the same codebase via
CVS.  They access the same database, so in some places I want to not
run the scheduled procs for the staging site.  That means that the
script which does the scheduling needs to know which site it's being
executed on.

I would normally do this with "ns_conn location", but that doesn't
work here as there is no connection when this code is executed.  The
only things which will identify the site for me are the
location/hostname or the path of the script, and I can't figure out
how to get either.

Can someone please tell me what I'm overlooking?

It seems like it would be a nice thing to add into OpenACS: knowledge of what type of installation it is. If we created a few simple functions that could determine what the server was (staging, development, production), then we could do a lot of neat things like wrap ns_sendmail with a debug mail operation to the developer when it is a developer site, etc...

Sorry, that doesn't answer your question. I haven't run into this problem personally, as I keep copies of the production database on my production server. I don't see why this couldn't be done for staging as well..

[ad_conn file] should give you the path of the script ...

Unfortunately, ad_conn doesn't work without a connection either.

The reason the two sites share a database is that the client wants it that way;  they're willing to give up the safety of having two for convenience of having the same data on both sites, without having to enter it twice.

How about [ns_info server]?

Thanks, Tom, that works!

We put the following in the nsd.tcl of the dev server 
ns_section "ns/server/${server}/acs/special_parameters"
ns_param dev_server true

and check

 if {![string is true [ad_parameter dev_server special_parameters]] } {
	do stuff on live server
}
