mmm I read the source well, it doesn't. It just give the status of
CouchDB : pid + if running or not. Also you can't know the port before
CouchDB is launched if port = 0 which is the way some app are
launching couchdb like desktop-couch.

They could live together, but it may be redundant at the end. Is this a problem
If we have some time I could work on another solution. For now I fail
though to find a way to get final port from couch in the shell script.
The only simple way I see for now is to name the CouchDB node and then
call some specific function with erlang that return the correct
information. The list of nodes could be get via erlang too. But do we
want to name the nodes ? (via -sname or such) .
If we don't name the nodes, there may be a way to do it via os pids,
but I don't know it yet.

Anyway couldn't it be done in a future version ? I don't want to
introduce some extra complexity for a 1.0. Really would like this
patch appear in 1.0 so it can help to port couchdbdesktop or any
alternative to others OS.

That can be done by parsing result of ps I think. Is there a way once
we have the pid to get the localstatelibdir of this pid ? So we could
read the uri or such ?
There maybe a way to do it via erlang but I don't know one actually .
if we could do a remote call on one sname we could get the port but we
don't set the sname actually.

Anyone used screen?
When you do "screen -l" you get a list of running screens.
"couchdb -s" could do something similar.
You could then do "couchdb -s PID" to get the status of that instance, with URL.
Thoughts?

You can make -s work by using different pid files for each instance.
I'm not sure how to make it know the port.

Mmm doable by parsing this file, though it will require to know where
the file is, which could be difficult. I wonder how -s works when

I'm not sure it works in this case :) Imo I would keep the simple way.

No, what I meant is that this patch should add that functionality. Hehe.
