[tarantool-patches] [PATCH v2 0/2] Do not promote vclocks in case of failure

[Georgy Kirichenko <georgy@tarantool.org>]

Promote tx and wal vclock only if corresponding row was successfully
written to wal. This prevents tarantool from skipping rows in case of
replication errors as well as from making lsn gaps after IO errors.

Branch: https://github.com/tarantool/tarantool/tree/g.kirichenko/gh-2283-dont-skip-rows-after-errors
Issue: https://github.com/tarantool/tarantool/issues/2283

Changes in v2:
  - commits 2 and 3 are squashed
  - test fixed according to review
  - comment fixed according to review

Georgy Kirichenko (2):
  Do not promote wal vclock for failed writes
  Promote replicaset.vclock only after wal
