Scripts used to build seastar shared library and package for ubuntu

Install from ubuntu ppa (for users)

Supported version: 18.04 (bionic)

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:compiv/cpv-project
sudo apt-get update
sudo apt-get install seastar

In addition, you have to install gcc-9 because the package is built with it.
(Why use gcc-9: seastar won't support old compiler for long period, and I don't want to add patches for old compiler)

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt-get install g++-9

Compile and execute example program (for users)

cd examples
g++-9 $(pkg-config --cflags seastar) tcp_echo_server.cpp $(pkg-config --libs seastar) -O3
./a.out

Compile and execute example program in debug mode with sanitizers (for users)

cd examples
g++-9 $(pkg-config --cflags seastar-debug) tcp_echo_server.cpp $(pkg-config --libs seastar-debug)
./a.out

Build local package (for advance users)

To build this package, gcc-9 is required, see install steps above.

sh build.sh local

Build source package and publish to ppa (for myself)

sh build.sh ppa
cd build
dput ppa:username/project seastar_version_source.changes

Performance tips

Because seastar implements custom task scheduler, the performance compare to other framework maybe lower on low end machine, one solution is set higher value of --task-quota-ms option, like --task-quota-ms=20, this solution has increase throughput by 35% on my vps. Of cause there will be some penalty, see this discussion for more details.
