Synchronous IDBMirrorVFS

[simc]

Hey! Would it be possible to create a version of the IDBMirrorVFS that works with a synchronous SQLite build?
Essentially a MemoryVFS with persistence?

It is possible, but how difficult it is depends on what you want exactly. IDBMirrorVFS isn't just MemoryAsyncVFS with persistence because it also allows multiple connections. Creating a synchronous version of IDBMirrorVFS that supports multiple connections could be done with the retry idea that OPFSCoopSyncVFS uses...but that's a tricky change to code.

If all you actually want is MemoryVFS with persistence - with only one connection and durability not guaranteed - then that is a much simpler task. It is so much simpler that I would probably start from scratch instead of starting with IDBMirrorVFS and ripping things out.

Thanks that helps a lot. A single connection is enough I'll manually sync the different tabs.

I've been trying to build something similar but couldn't get it to work (probably because I've never written a VFS before). I only need a single connection but cannot use the asynchronous version.
