I have my Zope-Process running with uid zope and uid zope in the group users. I am developing a product MyProduct in ZINSTANCE_HOME/Products/MyProducts with this setting: drwxrwxr-x 6 perry users 616 Feb 18 20:25 MyProduct when I refresh MyProduct in the control-panel, no .pyc files are created. the amazing thing is that when I run python as the user zope and do an import MyProduct in the Products the .pyc files are created with: -rw-r--r-- 1 lzope lzope 24433 Feb 18 20:38 Client.pyc also when I do a chown zope:users MyProduct and refresh the .pyc files are generated with permissions: -rw-r--r-- 1 lzope lzope 24433 Feb 18 20:38 Client.pyc the same is true if I do: chmod a+w MyProduct which I apparently don't want to do - Mit freundlichen Grüßen Joachim Schmitz -------------------------------------------------------------------- AixtraWare Ingenieurbüro für Internetanwendungen Telefon: +49-2464-8851, FAX: +49-2464-905163 --------------------------------------------------------------------
