The _make_config_values macro reduces duplication (both the item name and the types need to be available as C++ identifiers and as runtime strings), but is hard to work with. The macro is huge and editors don't handle it well, errors aren't identified at the correct location, and since the macro doesn't have types, it's hard to refactor. This series replaces the macro with ordinary C++ code. Some repetition is introduced, but IMO the result is easier to maintain than the macro. As a bonus the bulk of the code is moved away from the header file. Tests: unit (dev), manual testing of the config REST API * https://github.com/avikivity/scylla config-no-macro/v2 config: make the named_value type name available without requiring _make_config_values config: remove value_status from named_value template parameter list config: add named_value::value_as_json() api: config: stop using _make_config_values config: auto-add named_values into config_file config: add allowed_values parameter to named_value constructor config: convert _make_config_values to individual named_value member declarations and initializers
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.
Note: GCC >= 8.1.1 is require to compile Scylla.
Note: See frozen toolchain for a way to build and run on an older distribution.
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>
