Hi, Refering to this bug report https://bugs.launchpad.net/zodb/+bug/683751 And this usecases http://stackoverflow.com/questions/6168566/collective-xsendfile-zodb-blobs-a... It would be great if create mode of blobs would be configurable in ZODB directly. For UNIX Systems there could be 2 flags for folder creation mode and blob file permissions, i.e. BLOB_FOLDER_MODE = 750 BLOB_FILE_PERMISSIONS = stat.S_IRUSR | stat.S_IRGRP which are used then at the appropriate places. See here: http://pastebin.com/wNLYyXvw I don't know how this refers to NTFS, though. Further this configuration flags should be available in ZOPE and ZEO Server configuration files. Any doubts, suggestions, other ideas? Regards, Robert -- Robert Niederreiter Squarewave Computing Aflingerstraße 19 A-6176 Völs Tel: +43 699 160 20 192 Web: http://www.squarewave.at
