この投稿はまだまだ途中です。InfluxDBのパッケージ作成や開発環境をDebian6で1から作るときの説明になります。
公式でも開発環境のセットアップとかはあるけど、微妙に足りなかったりハマりどころがあるのでメモしときました。
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
