[Tarantool-patches] [PATCH 0/2] Qsync crash on WAL write fail

[Vladislav Shpilevoy]

The patchset fixes the crash when a synchronous transaction
couldn't to local master's WAL, getting an error from inside of
the WAL thread.

Note, the test is added to the existing file instead of creating
a new one intentionally. It is not so cheap to create new instance
for each new test, and also would complicate running all qsync
tests by prefix like this: `python test-run.py replication/qsync`.
Besides, the test is simple. Copy-pastable to console not counting
test_run:switch() calls.
