[PATCH 0/7] reftable: avoid reading and writing empty keys

["Han-Wen Nienhuys via GitGitGadget" <gitgitgadget@gmail.com>]

this series makes sure that the object record does not have to consider
empty keys (and therefore, a NULL memcpy destination)

while we're at it add some more tests, and fix a naming mistake.

Han-Wen Nienhuys (7):
  Documentation: object_id_len goes up to 31
  reftable: reject 0 object_id_len
  reftable: add a test that verifies that writing empty keys fails
  reftable: avoid writing empty keys at the block layer
  reftable: ensure that obj_id_len is >= 2 on writing
  reftable: add test for length of disambiguating prefix
  reftable: rename writer_stats to reftable_writer_stats
