Ah yes, the padding is currently only done on platforms that don't allow unaligned access to ints (e.g. Sparc)

git rev e2a7617d17368b5787fc24fbd017623d00fe162b

But what about 5-bytes keys from indexer?

• How ones should be compared, as a 4-byte int without MSB, or as a

padded 8-byte long?

The indexer doesn't use MDB_INTEGER so your question is irrelevant.

• Where is the padding code?

The code is in the git commit ID I already posted in my previous reply.
