[Tarantool-patches] [PATCH v5 0/4] replication: fix local space tracking

[Vladislav Shpilevoy]

Hi! Thanks for the patchset!

The branch has one failed job in Travis:
https://travis-ci.org/github/tarantool/tarantool/jobs/668688927?utm_medium=notification&utm_source=github_status
in replication-py/conflict.test.py. Can it be caused
by these changes?
