using python 2.4.5 Zope 2.11.1-final DirectoryStorage 1.1.19 First, is there a more preferable product to use to serve files, mostly PDF, from the file system with Zope? I suspect lock_file.py has changed since the DirectoryStorage product was last updated. I followed instructions on http://dirstorage.sourceforge.net/install.html to install DirectoryStorage. I got to step 11. "Start Zope" and at the end of Traceback 1 (see below) File "/usr/local/lib/python2.4/site-packages/DirectoryStorage/PosixFilesystem.py", line 12, in ? from ZODB.lock_file import lock_file ImportError: cannot import name lock_file There are no classes or methods named lock_file in lock_file.py so I changed the import statement in PosixFilesystem.py to from ZODB import lock_file Then the same thing occured in BaseDirectoryStorage.py and I made the same change to that import statement. (see Traceback 2) Now (see Traceback 3) I get File "/usr/local/lib/python2.4/site-packages/DirectoryStorage/LocalFilesystem.py", line 55, in engage raise DirectoryStorageError('Storage is locked by another process') DirectoryStorage.utils.DirectoryStorageError: Storage is locked by another process But I'm not sure how to overcome this or is this because the locK_file problem but I suspect so. I can't find anything that indicates Storage is locked except for the end of that traceback. I don't know if I need to do " from ZODB.lock_file import _lock_file " or something else. Any help would be appreciated.
