for certain lookups.
The rb_tree will act as a general purpose key/value storage, and
also give a performance boost in the cases where the other
simple alternative would be to use a linked_list.
On average this should give on average O(log n) lookups, while the linked_list
would be O(n) at worst.
Caveat, need to run the update script manually after changing the tests (adding or removing tests).
However, modifying existing tests does not require running the update script.
Added a copy of exotic in the repository
exotic automatically generates the skeleton code around the autotests in order to schedule
the tests.
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).
and comments.
This allows for:
'"foo bar"' can be represented as 'foo\ bar'.
And allows for comments using the hash symbol (#), but not inside
escapes or quotes. "#this is not a comment", \#this\ is\ not\ a comment.
All configuration file parsers should be rewritten using this functionality.
This revealed a few bugs:
* when sid allocator is full, then uhub will loop indefinitely when allocating one more (unlikely to occur).
* looking up a user object based on a sid that is out of range (off by one) returns invalid memory.
