I have seen this assertion where I specify two extended partitions exactly next to each other;

I assume you mean logical partitions; a partition table can have only
one extended partition.

Yes apologies for incorrect terminology.

In most cases, you can't have logical partitions right next to each
other.  Each logical partition must have its own partition table, just
before the partition starts.

particularly where I use a constraint generated with ped_constraint_exact(). Should the function add_logical_part_metadata just return success where the metadata length is zero?

No... in the cases libparted is complaining, you actually need a
non-zero gap.

Ah ok so this metadata partition is space for the partition table before each logical partition. In which case the assertion I saw was as expected. Thanks for the info.
