Programing

Asynchronous protocol with no influence of internet and server latency. Thread isolation for the important or heavy server task. It can be hosted on ADSL connection.

SGBD for Qt version: Mysql 5+, SQLite, PostgreSQL 9+. SGBD for epoll version (async to high performance): Mysql 5.5+, PostgreSQL 9+.

Prerequisites

Postgresql

You need to create this roles:

• catchchallenger-login
• catchchallenger-base

Then:

su -l postgres
cd server/databases/postgresql
echo 'CREATE DATABASE catchchallenger_login;' | psql postgres postgres
echo 'CREATE DATABASE catchchallenger_base;' | psql postgres postgres
echo 'CREATE DATABASE catchchallenger_common;' | psql postgres postgres
echo 'CREATE DATABASE catchchallenger_server;' | psql postgres postgres
psql catchchallenger_login postgres < catchchallenger-postgresql-login.sql
psql catchchallenger_base postgres < catchchallenger-postgresql-base.sql
psql catchchallenger_common postgres < catchchallenger-postgresql-common.sql
psql catchchallenger_server postgres < catchchallenger-postgresql-server.sql
echo 'GRANT ALL ON ALL TABLES IN SCHEMA public TO "catchchallenger-login";' | psql catchchallenger_login postgres
echo 'GRANT ALL ON ALL TABLES IN SCHEMA public TO "catchchallenger-base";' | psql catchchallenger_base postgres
echo 'GRANT ALL ON ALL TABLES IN SCHEMA public TO "catchchallenger-login";' | psql catchchallenger_common postgres
echo 'GRANT ALL ON ALL TABLES IN SCHEMA public TO "catchchallenger-login";' | psql catchchallenger_server postgres

Compiling

Use C++11

Dependency:

• zlib (can be disabled but it's for tiled map editor)
• Client
  • Qt openssl enabled to have QSslSocket or QtWebSocket
• Server
  • Qt if generic server
  • db
  • db driver (mysql, sqlite for game solo, postgresql, depands of you choice)
• Gateway
  • curl to download datapack via http

Hardware

You need CPU with support of unaligned access on 8/16/32Bits for the server at least (plan to support all CPU)

The server is actually 10-20MB of memory (1MB measured by massif) and 2KB by player
