"Refs #293 * Disables all normal service shutdowns. * Calls "stop()" explicitly for database (which in turn will also flush commitlog etc). Then just does a hard "_exit". * Add shutdown() + gate to commitlog to prevent data from being added once system shutdown is initiated. Will and does cause exceptions in write paths during shutdown. This is an explicitly asked for workaround series for the interdependency issues making shutdown as formulated by at_exit + sharded::stop unreliable right now. Proper ways of doing this would be to a.) Make services actually stop service when asked to (stop()) b.) Do shutdown in two steps; stop() and later delete. Note: I've left the old "at_exit" calls commented in main.cc/init.cc as a reminder that this is not a final solution."
#Urchin
##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
