[Tarantool-patches] [PATCH 0/3] Qsync too long WAL write

[Vladislav Shpilevoy]

The patchset fixes the issue with synchronous transactions
printing "too long WAL write" even when WAL write speed was fine.

The reason was the the "WAL write" time is measured at transaction
commit, which is far from the actual disk write for synchronous
transactions.

@ChangeLog
* Fixed a false-positive "too long WAL write" message for synchronous transactions.

Branch: http://github.com/tarantool/tarantool/tree/gerold103/gh-5139-too-long-wal
Issue: https://github.com/tarantool/tarantool/issues/5139

Vladislav Shpilevoy (3):
  txn: rename txn_complete_async to txn_on_journal_write
  txn: split complete into success and fail paths
  txn: warn "too long WAL" on write, not on commit
