2015-12-15Added GPL-compliant header to all sources and build scriptsHaru1-4/+20
Signed-off-by: Haru <haru@dotalux.com>
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.

2014-01-18Socket interfacedshennetsind1-43/+92

2013-12-17Fixed several compiler warningsHaru1-4/+8
- Warnings detected thanks to Xcode's compiler settings (more strict by default) and clang, warnings mostly but not only related to data sizes on 64 bit systems, that were silenced until now by very lax compiler settings. - This also decreases by a great deal the amount of warnings produced by MSVC in x64 mode (for the adventurous ones who tried that) - Also fixed (or silenced in case of false positives) the potential issues pointed out by the (awesome) clang static analyzer. - Patch co-produced with Ind, I'm merging and committing in his place!

2013-11-19Sanitized and improved several macros through the codeHaru1-13/+13

2013-11-13HPM Custom Data Struct Makeover!shennetsind1-1/+1
- Modified how the core handles it, making it easier to add new points. - Modified how plugins call it, calls were made shorter, e.g. 'HPMi->getFromSession(session[fd],HPMi->pid,0)' => 'getFromSession(session[fd],0)' -- check src/common/HPMi.h #defines for all the options - Added support for npc_data (getFromNPCD and so on) as requested in http://hercules.ws/board/topic/2923-hpm-custom-struct-npcs/ Signed-off-by: shennetsind <ind@henn.et>
2013-10-26Changed 'tick' variables to 64 bitHaru1-3/+2
- This fixes an issue with timers that stop working after about 24-49 days when the tick overflows (note that this may happen much earlier than that, and at hard to predict times, on some systems) - Updated the RDTSC help message in the configure script to also warn users about issues with SpeedStep enabled systems. - On Windows, tick() still has a resolution of 10~15ms (or even as low as 100ms on some systems). A TODO comment (thanks, Ai4rei) was added for a follow-up patch, as I want this one to be as small as possible) - Note: on Windows versions earlier than 6.x (Vista, Server 2008), the tick overflow issue is NOT fixed, since they don't support the function used to retrieve a 64 bit tick. This isn't a big issue, since those platforms are already - or going soon to be - out of their extended support period, and it's already advisable to upgrade, for other reasons. If you're the unfortunate user of such a system, it is recommended that you reboot your machine at least once every 49 days for Hercules to work reliably. - Note: To clear some doubts, since I've already been asked, this has absolutely NOTHING to do with 32/64 bit CPUs or OSes. It's all about a variable's size, not the size of registers of your CPU, and your 32bit CPU will be able to handle this just fine. Signed-off-by: Haru <haru@dotalux.com>
