> Merge "Run-time logging configuration" from Jesse
Includes patch from Jesse:
"Switch to Seastar for logging option handling
In addition to updating the abstraction layer for Seastar logging in `log.hh`,
the configuration system (`db/config.{hh,cc}`) has been updated in two ways:
- The string-map type for Boost.program_options is now defined in Seastar.
- A configuration value can be marked as `UsedFromSeastar`. This is like `Used`,
except the option is expected to be defined in the Boost.Program_options
description for Seastar. If the option is not defined in Seastar, or it is
defined with a different type, then a run-time exception is thrown early in
Scylla's initialization. This is necessary because logging options which are
now defined in Seastar were previously defined in Scylla and support for these
options in the YAML file cannot be dropped. In order to be able to verify that
options marked `UsedFromSeastar` are actually defined in Seastar, the
interface for adding options to `db::config` has changed from taking a
`boost::program_options::options_description_easy_init` (which is handle into
a `boost::program_options::options_description` which only allows adding
options) to taking a `boost::program_options::options_description`
directly (which also allows querying existing options).
Scylla also fully defers to Seastar's support for run-time logging
configuration."

Scylla
Quick-start
$ git submodule update --init --recursive
$ sudo ./install-dependencies.sh
$ ./configure.py --mode=release
$ ninja-build -j4 # Assuming 4 system threads.
$ ./build/release/scylla
$ # Rejoice!
Please see HACKING.md for detailed information on building and developing Scylla.
Running Scylla
- Run Scylla
./build/release/scylla
- run Scylla with one CPU and ./tmp as data directory
./build/release/scylla --datadir tmp --commitlog-directory tmp --smp 1
- For more run options:
./build/release/scylla --help
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 -p $(hostname -i):9042:9042 -i -t <image name>
