パッケージのインストール

sudo apt-get install mercurial bzr protobuf-compiler flex bison valgrind g++ make curl rpm build-essential git

GoのInstall

curl -O https://storage.googleapis.com/golang/go1.2.2.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.2.2.linux-amd64.tar.gz
echo -ne 'export GOROOT=/usr/local/go\nexport PATH=$PATH:/$GOROOT/bin\n' >> ~/.bash_profile
source ~/.bash_profile

InfluxDBのソースコードを取得

git clone https://github.com/influxdb/influxdb.git

InfluxDBをビルドする

cd influxdb
./configure
make

RVMのインストール (Package作成には現在RVMが必要です)

curl -sSL https://get.rvm.io | bash -s stable
echo '[ -s ${HOME}/.rvm/scripts/rvm ] && source ${HOME}/.rvm/scripts/rvm
' >> ~/.bash_profile
source ~/.bash_profile
rvm install 1.9.3

rvm 1.9.3@influxdb do bundle install
make package

rvm 1.9.3@influxdb do bundle installがわからなくでfpmでドはまりした

Testの実行方法

全てのテストを実行する場合はこう (5〜6分ぐらいかかるかも)

make test

integration/data_testだけ実行する場合

make integration_test only=DataTest verbose=on

Debug環境の作成

PythonとGDBが古いので個別にインストール

git clone git://github.com/yyuu/pyenv.git .pyenv
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
source ~/.bash_profile
pyenv install 2.7.5
pyenv shell 2.7.5

wget http://ftp.gnu.org/gnu/gdb/gdb-7.6.1.tar.gz
tar zxf gdb-7.6.1.tar.gz
cd gdb-7.6.1
./configure --prefix=/opt/gdb/7.6.1 CFLAGS="-g -O2 -Wno-string-plus-int"
make
sudo mkdir -p /opt/gdb/7.6.1
sudo make install
echo 'add-auto-load-safe-path /usr/local/go/src/pkg/runtime/runtime-gdb.py' >> ~/.gdbinit

InfluxDBのデバッグをする時は

O_BUILD_OPTIONS='-gcflags "-N -l"' make build
/opt/gdb/7.6.1/bin/gdb ./daemon

例えばTop/BottomのAggregatorを開発した時はこんな感じで見ていたりしました。
Buildに数秒かかって面倒なのでgdb使うと大分はかどります
