2015-12-02Fixed an issue with the socket send/receive timeouts in WindowsHaru1-12/+27
- According to https://msdn.microsoft.com/en-us/library/windows/desktop/ms740476(v=vs.85).aspx setsockopt() for SO_RCVTIMEO/SO_SNDTIMEO require a DWORD argument, unlike their POSIX equivalent, requiring a struct timeval. - Always keep in mind: When you see a Microsoft API function that looks like a duck, swims like a duck, quacks like a duck, it most certainly is not a duck. - Thanks to ultramage.

2015-08-15HPM compatibility improvementsHaru1-0/+3
Improved compatibility, portability and standards conformance. - Since it is not possible to portably and reliably re-use the core's symbols in plugins, symbols are no longer exported unless explicitly required, in the UNIX builds. This mimics the Windows behavior and adds HPM compatibility to OSes such as FreeBSD. Credits to Andrei Karas for making this possible. - For convenience, it is no longer necessary to call GET_SYMBOL, since the plugin will automatically import all the available symbols when it's loaded, depending on the included headers. - Plugins are now supposed to include the "common/hercules.h" header before including anything else. Incluing common/HPMi.h, common/cbasetypes.h or conf/core.h is no longer necessary, as those are guaranteed to be automatically included by hercules.h. - HPM API version bumped to 1.1.

2015-08-11subnet.conf overhaulHaru1-0/+187
The subnet.conf system has been rewritten to offer greater flexibility, and to fix some issues that appeared with 838321a36c79e71117320154c9b611c99e93af03. It is now possible to enter, separately, LAN subnets: - `lan_subnets`: This is essentially the same feature present in the old subnet.conf. Each entry in this list defines a (LAN, private) subnet the server is in. Clients connecting from the same subnet, will be redirected to the LAN IP rather than the default public IP. The format has been simplified, and it only requires one IP and one subnet mask (as opposed to a character and a map server IP). - `allowed`: Allowed IPs are IP ranges a server (char to login or map to char) can connect from. Any attempt to connect as a server from an IP not included here, will fail. For convenience, a wildcard range (matching all possible IP addresses) has been provided (`0.0.0.0:0.0.0.0`), but it is very advisable to edit it to a more restrictive set. - `trusted`: Trusted IPs are IP ranges excluded from the IPban checks. This may be useful, for example, to exclude the server's own IP from ipbans, in case of false positives. Any IP ranges added to this list are also implicitly included in the allowed IP ranges.
