Hi Lucasz,
if I understand your other mail correctly, the office dies for some
reason. You may want to attach a debugger or something to see what happens.
How are you actually starting the office process? If it is under your
control, you may want to issue a "wait" (or similar) system call. The
moment "wait" returns you know the process died.
Just try the non-headless approach to see if it does crash as well,
obviously headless and non-headless should behave the same wrt to the
API :-)
Regards
Kay

Hi Lucas,
Here are two things you may try :
- use a pipe connection instead of a socket connection, and see if you still
lost connection
ok. lets try the pipe..
What is the difference between socket and a pipe as far as oo? Can I
start multiple instances of oo with different pipe names and then use
these pipe names for multiple programs that start around the same
time?
doing....
changed the startup from
/usr/bin/openoffice -accept="socket,host=localhost,port=8100;urp;"
-norestore -nologo -headless -nofirstwizard
to
/usr/bin/openoffice -accept="pipe,name=localhost_app;urp;" -norestore
-nofirstwizard -nologo -headless
Now in the code I did:
import uno
from com.sun.star.beans import PropertyValue
from com.sun.star.connection import NoConnectException
localContext = uno.getComponentContext()
resolver =
localContext.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver",
localContext)
context = None
context =
resolver.resolve("uno:pipe,name=localhost_app;urp;StarOffice.ComponentContext")
desktop =
context.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop",
context)
but still get the connection lost....no change...(I wonder if I can
use the NoConnectException somehow??)
troubleshooting....
I've tried recreating the cursor every time the new section/action
needs to be done. This has improved the process but still 1/5 fail in
headless.
What I noticed is that if headless process crashes, I can start the
non-headless process and that will finish just fine, so it seems as
headless startup will lose connection more often then the non headless
one.
Since I start and stop oo from the script I really need to get the
headless package to work properly.
- check that the OOo process is still running. Actually, you may want to use
the subprocess module instead of the os one (you just be loosing
compatibility with Python 2.3). You would be able to grab errors from the
stderror channel of your process. I don't know if it throw any message
there, but in case it does, you'd be able to read it.
There are no error messages when oo crashes. If I start the oo on the
socket then process is still running but its no longer listening on
the socket.
This will show a lot of soffice processes after few days of running
the process in cron.... ps -ea | grep soffice
But this command will show that none of them are listening
anymore...netstat -atpen | grep soffice
As far as pipe, i see its closing right now but I would need few days
to see if the process closes when using cron?
Ideas?
Thanks,
Lucas

Hi Lukasz,
this is a Python question, right?
Typically connections die, because one of the hosts get disconnected or
one
of the applications do terminate.
Do you have a hint, which case is yours?
It seems as there is a exception in openoffice services. Service
terminates without sending back an error message, and its no longer
listening on the port.
When that happens I get a message on the next oo call that the
connection was lost. So at this point I'm looking for a way for oo to
tell me that it failed, or look at some log that oo? creates to see
why it failed? Is there a log for the headless services oo is running?
Thanks,
Lucas
