Last night I was toying around with the initialization of the virtual tables I use as shared IPC mechanism in Vault-OS to run messages from the post office to the web server. The mailbox handles messages from daemon processes (now I have them running from inside of VOS at bootup) and provides them globally through SQLite shared memory tables.
Lo and behold, turns out there is an entire aspect of SQLite I don't even know about called virtual file systems. Accessed by the same queries as everything else. Mind. Blown. This in itself would be a marvel if this is all that SQLite did. In addition to all the other stuff it does I think this makes SQLite the most amazing public domain library on Earth. At times it is as if the author of SQLite was anticipating the needs of the VOS web server and writing the features needed to support that functionality.
