"Fixes: #469 We occasionally generate memtables that are not empty, yet have no high replay_position set. (Typical case is CL replay, but apparently there are others). Moreover, we can do this repeatedly, and thus get caught in the flush queue ordering restrictions. Solve this by treating a flush without replay_position as a flush at the highest running position, i.e. "last" in queue. Note that this will not affect the actual flush operation, nor CL callbacks, only anyone waiting for the operation(s) to complete. To do this, the flush_queue had its restrictions eased, and some introspection methods added."

##Building Scylla
In addition to required packages by Seastar, the following packages are required by Scylla.
Submodules
Scylla uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --recursive
Building scylla 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 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
Building Fedora-based Docker image
Build a Docker image with:
cd dist/docker
docker build -t <image-name> .
Run the image with:
docker run -i -t <image name>
