runMigrationSilently doesn’t work

[Profpatsch]

On my linux machine runMigrationSilently just returns an empty lists and still prints everything to <wherever I log it>.

The code uses capture_ from silently, which tries to capture a handle output, writes it to a temp file and reads that file back again. That’s quite a brittle hack! And probably completely unnecessary …

I presume you mean runMigrationSilent. I don't know how it could return an empty list if there was a migration to apply.

Do you want this function to be deprecated?

[Profpatsch]

I think it’s a good function to have, but it should not try to capture from the output handle, rather use internal data structures and return them instead of printing.
