2014-02-24Fixed console parse gm command crash on select commandsshennetsind1-2/+2
Also fixed an issue with socket flushing Signed-off-by: shennetsind <ind@henn.et>
2014-01-18Socket interfacedshennetsind1-43/+92
We designed this one with having as little changes required elsewhere in mind, thus the way most socket-related things are called has not changed. Plugins may now take a greater advantage of the socket features. Signed-off-by: shennetsind <ind@henn.et>
2014-01-11Fixed Bug 7960shennetsind1-1/+1
http://hercules.ws/board/tracker/issue-7960-scriptc-warnings/ Also applied a temporary adjustment due to ERS_OPT_CLEAN not being consistent (decent fix will follow up, haru and i are working on it) -- thanks to kyeme for pointing it out! Signed-off-by: shennetsind <ind@henn.et>

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! Signed-off-by: Haru <haru@dotalux.com>
2013-11-19Sanitized and improved several macros through the codeHaru1-13/+13
- Sanitized all potentially unsafe macros (related eA:15259) - Improved some function-like macros to evaluate their argument only once and keep it in a temporary variable. This improves performance in the damage calculation related code. Signed-off-by: Haru <haru@dotalux.com>
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>
2013-09-25Renamed iTimer interface to timer.shennetsind1-6/+6
Also removed duplicate mentions of timer within calls to shorten.

sockets. Connections that go over the limit are closed. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@13469 54d463be-8e91-2dee-dedb-b68131a5f0ec
