Generally I don't like when someone named himself as 'master'. There is so much hype on this topic, and with very little practical output. What I can notice about Toma:
1.When I had worked mostly on hi-level part of c6 and newer, implementing sieges on c6, functionality of clan halls, quests and so on - knowledge of key timeouts was important to build reliable server. As from 'master', I expected to hear from him some real numbers - for network connections, server timeouts, database requests, etc. With respect to C++ implementation. Not just outlandish numbers. Every person who cheated with server, will say that 10 ms - is not RTT of the tcp packet, but minimal tick time of the server.
2.Also, he failed to explain the principal difference, between tcp/udp implementations.
Same about understanding of testing on single machine vs testing on real networks. Anyone who hold his own l2 server for more than year, surely know the difference.
3.About published version of sources..
A).That archives just lack - basic data stats, content of db tables - to operate the C++ build normally. Without that data, that dis-asmed piece of old garbage have no practical usage. From that point, more valuable to have java-compiled build of the server, with complete data pack - to be able to operate easily, from the single Linux machine.
B).On quality of the code: Toma still can use any of old C++ standard, even which is 20 years old, still use malloc/free in cpp code and other bad practices. This will not help you to make good server, but rather turn away from making it. My advice: look in other places, ask people who have real knowledge.
