[PATCH v2 08/10] Rewrite checkpoint daemon in C

[Konstantin Osipov]

* Vladimir Davydov <vdavydov.dev at gmail.com> [18/12/09 00:15]:
> Long time ago, when the checkpoint daemon was added to Tarantool, it was
> responsible not only for making periodic checkpoints, but also for
> maintaining the configured number of checkpoints and removing old snap
> and xlog files, so it was much easier to implement it in Lua than in C.
> However, over time, all its responsibilities have been reimplemented in
> C and moved to the server code so that now it just calls box.snapshot()
> periodically. Let's rewrite this simple procedure in C as well - this
> will allow us to easily add more complex logic there, e.g. triggering
> checkpoint when WAL files exceed a configured threshold.
> 
> Note, this patch removes a few cases from xlog/checkpoint_daemon test
> that tested the internal state of the checkpoint daemon, which isn't
> available in Lua anymore. This is OK as those cases are covered by
> unit/checkpoint_schedule test.

OK to push.
