Empty namespaces are not exported on exit

[quantuminformation]

If I click delete on the root node the data is removed in the browser.

Im using RUNNING_LOCAL=true firebase emulators:start --only database,functions --inspect-functions --import=./seed --export-on-exit

however if I close the terminal and restart all data is still there. The only way I can remove the data on restart is to delete the seed file.

Hey there,

Thanks for the report. It sounds like this is working-as-intended - --export-on-exit does not overwrite the seed file. It sounds like you'd like for an option that makes whatever the emulator state is at exit to be what it is at startup. I've filed b/169081327 as an internal feature request.

Thanks,
~Malcolm

Ah, so when does the seed file get populated?

Actually I think it is supposed to update the seed file ... will look into this.

But this should be on firebase-tools

@quantuminformation ok so I think I know what's happening! When we do the export we ignore any "empty" namespaces, which are databases that have no data. The reason for this is that sometimes during testing (especially with @firebase/testing) people create many databases that they don't want exported.

I think what we need to do is remember which namespaces were imported and then make sure to always export those, even if they're empty at the end.
