"Refs #293 * Add a commitlog::sync_all_segments, that explicitly forces all pending disk writes * Only delete segments from disk IFF they are marked clean. Thus on partial shutdown or whatnot, even if CL is destroyed (destructor runs) disk files not yet clean visavi sstables are preserved and replayable * Do a sync_all_segments first of all in database::stop. Exactly what to not stop in main I leave up to others discretion, or at least another patch."

##Building Urchin
In addition to required packages by Seastar, the following packages are required by Urchin.
Submodules
Urchin uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --recursive
Building urchin on Fedora
Installing required packages:
sudo yum install yaml-cpp-devel lz4-devel zlib-devel snappy-devel jsoncpp-devel thrift-devel antlr3-tool antlr3-C++-devel libasan libubsan
Building urchin on Ubuntu 14.04
Installing required packages:
sudo apt-get install libyaml-cpp-dev liblz4-dev zlib1g-dev libsnappy-dev libjsoncpp-dev
Building Fedora RPM
As a pre-requisite, you need to install Mock on your machine:
# Install mock:
sudo yum install mock
# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock
Then, to build an RPM, run:
./dist/redhat/build_rpm.sh
The built RPM is stored in /var/lib/mock/<configuration>/result directory.
For example, on Fedora 21 mock reports the following:
INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result
