Frequent errors when first starting Jupyter #788

@lukemarsden reports:

I get this error fairly often when starting jupyter on a runner (when the runner didn’t yet have the project dot). always resolves when running again but it’s a bad look. is there some asynchrony in dotmesh knowing its commits after an initial pull/clone?

in this case it’s the machine under my desk in Bristol, which is quite fast bare-metal machine in case that makes a difference

Digging through the code, I eventually found InitFilesystemMachine in dotmesh, which does the following:

        go s.filesystems[filesystemId].Run() // concurrently run state machine

        return s.filesystems[filesystemId], false

This suggests filesystem creation happens in background, if I'm interpreting code correctly...
