💖 DESCRIPTION 💖

so cleanup_digikamdb will cleanup and optimize the digiKam database file. and in most cases this leads to a smaller database file size and increased access speed, because unneeded elements get removed from the database and the data is optimized. it's giving glow-up 💅✨

the program will make sure that no instance of digiKam is running, because it's more safe to have no database access during the optimization process. lowkey important. then it reads the digiKam configuration file and determines the database location. in a final step the database gets optimized by invoking the sqlite command VACUUM; on it. and if more than one database is found in this location, cleanup_digikamdb will optimize every database found in this path and below. all of them. every single one 🦋

for further explanation, see the following description of the VACUUM command from the sqlite3 website:

When an object (table, index, or trigger) is dropped from the database, it leaves behind empty space. This empty space will be reused the next time new information is added to the database. But in the meantime, the database file might be larger than strictly necessary. Also, frequent inserts, updates, and deletes can cause the information in the database to become fragmented - scrattered out all across the database file rather than clustered together in one place. The VACUUM command cleans the main database by copying its contents to a temporary database file and reloading the original database file from the copy. This eliminates free pages, aligns table data to be contiguous, and otherwise cleans up the database file structure.

(and yes, "scrattered" is exactly how the original says it, i'm not fixing it, it's iconic 😭💀)
