- We used this directory to create a isbg/ one to store cached data:
- lock file.
- password file.
- chached lists of
uids
.
Note
For best xdg_cache_home detection, install python-xdg.

logger
¶ Object used to output info. It’s initialized when ISBG is initialized.
Type: logging.Logger
These are attributes derived from the command line and needed for normal operations:
-
verbose
¶ a property that if it’s set to True show more information. Default to
False
.
These are attributes derived for the command line, and needed for SpamAssassin operations:
-
deletehigherthan

None
.Type: bool
-

None
.Type: str
These are attributes derived from the command line and related to the lock file:
-
lockfile
¶ Full path and name of the lock file.
The path it’s initialized with the xdg cache home specification plus /isbg/ and with the name
lock
.Type: str
These are attributes derived for the command line, related to the IMAP password and files:

set_filename

/isbg/Parameters: - imapsets (isbg.imaputils.ImapSettings) – Imap setings instance.
- filetype (str) – The file type.

-
pastuid_read
(uidvalidity, folder='inbox')¶ Read the uids stored in a file for a folder.
pastuids_read keeps track of which uids we have already seen, so that we don’t analyze them multiple times. We store its contents between sessions by saving into a file as Python code (makes loading it here real easy since we just source the file)
-

(uidvalidity, origpastuids, newpastuids, folder='inbox')¶ Write the uids in a file for the folder.
-
do_list_imap
