* Allow NodeTimer, ABM and block mgmt interval changes.Auke Kok2016-03-19
| | | | | | | | | | | | | | | | | | | | | | ABM's are hardcoded to run every 1.0s, NodeTimers are hard coded to run at every 1.0s. Block mgmt is running every 2.0sec. However, these timers can be better tuned for both higher and lower values by server owners. Some server owners want to, and have the resources to send more packets per second to clients, and so they may wish to send smaller updates sooner. Right now all ABM's are coalesced into 1.0 second intervals, resulting in large send queues to all clients. By reducing the amount of possible timers, one can get a far better response rate and lower the perception of lag. On the other side of the camp, some servers may want to increase these values, which again isn't easily doable. The global settings abm_interval and nodetimer_interval are set to current values by default. I've tested with 0.2/0.5 type values and noticed a greatly improved response and better scattering of nodetimers, as well as enjoying not faceplanting into doors with pressure plates anymore.
* Add consistent monotonic day counter - get_day_count()Auke Kok2016-03-09
| | | | | | | | | | | | | | | | | | | | | | | | I've written several experimental bits of code that revolve around the need for a consistent calendar, but implementing one is extremely hard in mods due to time changes and mods overriding core.get_timeofday(), which will conflict. The second part of the problem is that doing this from a mod requires constant maintenance of a settings file. An implementation in core is trivial, however, and solves all of these problems at virtually no cost: No extra branches in server steps, and a single branch when minetest.set_time_of_day(), which is entirely reasonable. We store the day_count value in env_meta.txt. The use case is obvious: This change allows mods to create an actual virtual calendar, or properly account for seasonal changes, etc.. We add a "/days" chatcommand that displays the current day count. No permissions are needed. It can only retrieve the day count, not modify it.

* Time: use locks againest312015-11-04
| | | | | | | | | | | | | | | The Atomic implementation was only partially correct, and was very complex. Use locks for sake of simplicity, following KISS principle. Only remaining atomic operation use is time of day speed, because that really is only read + written. Also fixes a bug with m_time_conversion_skew only being decremented, never incremented (Regresion from previous commit). atomic.h changes: * Add GenericAtomic<T> class for non-integral types like floats. * Remove some last remainders from atomic.h of the volatile use.
* Time: Remove serverside getter, and use atomic operationsest312015-11-03
| | | | | | | | It isn't possible to use atomic operations for floats, so don't use them there. Having a lock is good out of other reasons too, because this way the float time and the integer time both match, and can't get different values in a race, e.g. when two setTimeofDay() get executed simultaneously.
* Add DISABLE_CLASS_COPY macro (and use it)kwolekr2015-10-27
| | | | | | | | | Use this macro to disallow copying of an object using the assignment operator or copy constructor. This catches otherwise silent-but-deadly mistakes such as "ServerMap map = env->getMap();" at compile time. If so desired, it is still possible to copy a class, but it now requires an explicit call to memcpy or std::copy.
* Environment: Time of day fixes and add serverside getterest312015-10-27
| | | | | | | | -> Put access to time variables under the time lock. -> Merge both time locks, there is no point to have two locks. -> Fix the lock being released too early in Environment::setTimeOfDay -> Add serverside getter so that you don't have to get the environment if you only have the server

* Save and remove player by pointerLoic Blot2015-09-23
| | | | | | Why doing things simple ? Use pointer instead of strings to save players and remove them. Saving players by name does a lookup to find pointer we already have ! Idem with removePlayer Also remove unused removePlayer(peer_id), it's never called
* Little optimization on getAdded/Removed activeobjects per player loop.Loic Blot2015-09-19
| | | | | Use std::queue instead of std::set, we don't need such a heavy container. Don't convert position to int to convert it back to float in the next function.
* Change m_client_event_queue's type to std::queueLoic Blot2015-09-08
| | | | | As indicated in its name, m_client_event_queue should be a queue. Change std::list to std::queue to improve the queue's performance.
* Clean up threadingShadowNinja2015-08-23
| | | | | | | | | | | | | | | | | | | | * Rename everything. * Strip J prefix. * Change UpperCamelCase functions to lowerCamelCase. * Remove global (!) semaphore count mutex on OSX. * Remove semaphore count getter (unused, unsafe, depended on internal API functions on Windows, and used a hack on OSX). * Add `Atomic<type>`. * Make `Thread` handle thread names. * Add support for C++11 multi-threading. * Combine pthread and win32 sources. * Remove `ThreadStarted` (unused, unneeded). * Move some includes from the headers to the sources. * Move all of `Event` into its header (allows inlining with no new includes). * Make `Event` use `Semaphore` (except on Windows). * Move some porting functions into `Thread`. * Integrate logging with `Thread`. * Add threading test.
