        "description": "=========\nFilestore\n=========\n\nThe filestore is an easy way to to process files with multiple processes\nwithout needing locks.\n\n\nInitialize a FileStore\n======================\n\nCreate a filestore in a temporary area:\n\n>>> import tempfile\n>>> store_dir = tempfile.mkdtemp()\n>>> from gocept.filestore import FileStore\n>>> filestore = FileStore(store_dir)\n>>> filestore\n<gocept.filestore.filestore.FileStore object at 0x...>\n\nSo far nothing has happend:\n\n>>> import os\n>>> os.listdir(store_dir)\n[]\n\nBefore using the store we need to prepare it:\n\n>>> filestore.prepare()\n\nPrepare has created the tmp/new/cur directory structure:\n\n>>> sorted(os.listdir(store_dir))\n['cur', 'new', 'tmp']\n\nCalling prepare again does nothing:\n\n>>> filestore.prepare()\n>>> sorted(os.listdir(store_dir))\n['cur', 'new', 'tmp']\n\n\nUse a FileStore\n===============\n\nAdding files to the store works with the `create` method:\n\n>>> f = filestore.create('a-file')\n\nFiles are created in the 'tmp' area with the 'w' mode (if not specified):\n\n>>> f\n<open file '.../tmp/a-file', mode 'w' at 0x...>\n\nWe find the file in the tmp area. Note that `filestore.list` lists files with\ntheir full path names, so we could feed the name directly to file/open:\n\n>>> filestore.list('tmp')\n['.../tmp/a-file']\n\nWe got a plain file back, so write to it:\n\n>>> f.write('Die Ente bleibt draussen!')\n>>> f.close()\n\nWe have finished writing our file, so we can move it to the `new` space for\nother applications to pick it up:\n\n>>> filestore.move('a-file', 'tmp', 'new')\n>>> filestore.list('tmp')\n[]\n>>> filestore.list('new')\n['.../new/a-file']\n\nThe move operation uses os.move which is supposed to be atomic. When another\nprocesses \"sees\" the file it can directly work with it and move it to 'cur':\n\n>>> filestore.move('a-file', 'new', 'cur')\n>>> filestore.list('new')\n[]\n>>> filestore.list('cur')\n['.../cur/a-file']\n\nFiles can be copied, too:\n\n>>> filestore.copy('a-file', 'cur', 'tmp')\n>>> filestore.list('cur')\n['.../cur/a-file']\n>>> filestore.list('tmp')\n['.../tmp/a-file']\n\n\nCleanup\n=======\n\nRemove the temporary directory after testing:\n\n>>> import shutil\n>>> shutil.rmtree(store_dir)",
