db-synthesizer has a sanity check when (over)writing a directory to check whether it actually plausibly contains a ChainDB. Previously, this check was only succeeding when the directory would contain exactly three entries named
immutable
/ledger
/volatile
. This is somewhat annoying, as ChainDBs usually contain the foldergsm
as well as files likeclean
/lock
/protocolMagicId
in addition.This PR relaxes the check, as discussed with @mgmeier: We now only check whether the subdirectories are a subset of
immutable
/ledger
/volatile
/gsm
, and fail if any other subdirectories are present.Follow-up to #1206
