New class `Config` | Update numeric replies functions parameters | Update `std::map typedef` in Channel

[ysengoku]

Config class

This class has all ISUPPORT parameters defined in server.conf file:

CASEMAPPING=ascii
CHANLIMIT=10
CHANMODES=i,t,k,l
CHANNELLEN=50
CHANTYPES=#
HOSTLEN=63
KICKLEN=255
MAXLIST=100
MAXTARGETS=4
MODES=3
NETWORK=42IRC
NICKLEN=9
PREFIX=(o)@
TOPICLEN=307
USERLEN=10
USERMODES=ior

These default values are from RFC1459(IRC 1993).

Add a global variable gConfig so that we can access to configuration from everywhere.

USAGE (Arguments are examples.)

• numeric parameters: gConfig->getLimit("CHANLIMIT")
• other parameters: gConfig->getParam("NETWORK")

Channel class

• Update map type to typedef std::map<int, Client*> and related function. We should use pointer to avoid to duplicate Client instance.

PING command

Usage:

• Hexchat /PING without arguments
• netcat PING token (e.g. PING hello)

---

Other updates

numericReplies

• Update function parameters from int fd, const std::string &nick to const Client &client
• Add a unit test function (but at least one client connection needed so that the server sends test messages). It runs with make debug.

Client class

• Update functon name from getNickName() to getNickname()
• Add _hostName variable
• Update constructor using initialization list except structure valiable

Channel class

• Add 2 variables: std::string _type and std::string _nameWithPrefix
• Add 3 macros: REG_CHAN "#" , PUBLIC_CHAN "=" and CHAN_OP "@"

Server class

• Update constructor using initialization list except signal
• In void Server::acceptNewClient() as following: Add host name setting Update Client instance creation timing (After host name setting so that we can call Client constructor with arguments)

Previous version

Client cli();
cli.setFd(newClientFd);
cli.setIp(inet_ntoa(cliadd.sin_addr));

Update

std::string clientIp = inet_ntoa(cliadd.sin_addr);
struct hostent* host = gethostbyaddr(&cliadd.sin_addr, sizeof(cliadd.sin_addr), AF_INET);
std::string hostName;
if (host->h_name == NULL || sizeof(host->h_name) == 0 ||
      static_cast<size_t> (host->h_length) > gConfig->getLimit("HOSTLEN"))
  hostName = clientIp;
else
  hostName = host->h_name;
Client cli(newClientFd, clientIp, hostName);
