another thread to the mainthread in a safe manner.
This is used for the DNS lookup code, and can also
be used by the signal handler to safely report actions back
to the application mainloop without using global variables.
This happened due to the network polling mechanism had nothing to poll
for, so it returned immediately only to be called again (during DNS lookup).
This fix introduces a control pipe that is polled for reading, althoug nothing
is ever sent to that pipe. But, it can be used instead of the signal
handler approach which is currently used for terminating the program.
Previously you would have to do something like this:
for (type foo = (type) list_get_first(list); foo; foo = (type) list_get_next(list)
{
/* code */
}
Now, you can instead write this as:
LIST_FOREACH(type, foo, list,
{
/* code */
})
Basically, boilerplate stuff including the casting is gone.
Fix bug #185 - Args of !commands lost/damaged.
All string arguments were incorrectly freed after being added to the argument list for a command.
Instead this fix makes sure it is properly copied into a new string, and by doing so this requires
a new API for dealing with hub command arguments in a type safe manner, and also allows for each
argument to be cleaned up properly when the command is no longer needed.
This also fixes issues with parse errors for certain types, and optional arguments (previously it was impossible
to tell the difference for an integer with value 0 or if no integer was given).
All arguments can now be accessed through the new functions
hub_command_arg_reset() and hub_command_arg_next().
These functions are also exposed to plug-ins.
The argument type notations for 'n' has changed to mean nick (string),
and 'u' is used for a user (struct hub_user - must be online).
Dynamic commands are user commands that can be added dynamically to
the hub by a plugin.
The example plugin (mod_example.c) adds a !example command that when
invoked send a message to the user who invoked it.
will simply cause the hub to close the connection.
Fix problems with write events not being processed due to a read event taking presendence.
Fix bug #86: Windows does not have "getrlimit()".
