Hi,
I am curious to your experience with unoconv (a module part of
OpenOffice / LibreOffice and
used in Tryton to convert ODT files to PDF or other formats).
We use LibreOffice 3.6, IIRC mainly because OpenOffice had Java
dependencies that we did not want to install.
We are also still on Tryton 2.4.
On one of our production servers we have a lot of stability issues.
Unoconv crashes several times a month and all we can do is kill the
running soffice.bin and unoconv processes
and restart the unoconv deamon. And then hope it will not happen again
soon. When it does, the customer has to kill the client process to
restart.
On our development server it's quite stable. But on this machine
unoconv is idle most of the time. On the
production server it is much more busy, as I think about all of the
customer's documents are in PDF format.
Tryton 2.4 originally uses pipes, but we had even more stability
problems with this. So I changed it to sockets:
unoconv = socket,name=trytond;urp;StarOffice.ComponentContext
And this is how I start the deamon:
/opt/libreoffice3.6/program/soffice --display :0.0 --norestore
--headless
--accept="socket,host=localhost,port=2002;urp;StarOffice.ComponentContext"
For us this improved stability a lot, but it's still not good enough.
Anyone willing to share their experience with unoconv on a busy server?
We also had some unoconv crashes on both, production and development
server. Repeating the task from GUI always resolved the issue. Because
of that we put the loop into the source code like this:
try:
errcnt = 0
while True:
proc = subprocess.Popen(cmd, stdout=subprocess.PIPE)
stdoutdata, stderrdata = proc.communicate()
if proc.wait() != 0:
if errcnt < 5:
errcnt += 1
continue
else:
raise Exception(stderrdata)
return stdoutdata
finally:
os.remove(path)
in report.py and since 4 months we had no more problems.
Just one more thing: Ususally there is just one person creating reports
on the server and it is not *really* busy.
Regards,
Vincent
Hope it helps
