est31 6c81be51ff Fix object position border checking 
Borders have to be converted into BS format in order to be accurately comparable to
object positions.

est31 f61f817b9c Disallow placing entities outside safe boundaries 
Entity positions are serialized as F1000. Disallow placing
entities outside safe borders with the minetest.add_entity
call.

Note that this patch only enforces those boundaries for
placing entities, moving entities that move outside boundaries
aren't affected.

Thanks to @nanepiwo for pointing this out.

est31 283bf97a1c Serialisation: documentation fixes, clarifying renames and whitespace fixes 
1. Do two renames:
	* SER_FMT_CLIENT_VER_LOWEST -> SER_FMT_VER_LOWEST_WRITE
	* SER_FMT_VER_LOWEST -> SER_FMT_VER_LOWEST_READ
Now the two define values are consistently named with the _WRITE defines
SER_FMT_VER_{HIGHEST,LOWEST}_WRITE, and to better point out what the two
serialisation versions actually are for.

2. wrap some lines in doc/worldformat.txt, and point out that the node
timers are serialized at a later point, as this can cause confusion about
what now happens (if one doesn't strictly read the if block's conditions).

3. some whitespace fixes in NodeTimerList::serialize, and one new comment.

est31 06a2eee692 Mapblock: nodecount refactor 
Spare direct multoplication, use constant MapBlock::nodecount instead of
local nodecount variables.

Also use strides at one place instead of multiplications.

kwolekr 46684beec1 Record MapBlock modification reasons as flags instead of strings 
This improves performance of MapBlock::raiseModified by a factor of 6.
Also, clean up mapblock.h a bit and inline small functions.

Craig Robbins ced6d20295 For usages of assert() that are meant to persist in Release builds (when NDEBUG is defined), replace those usages with persistent alternatives 2015-03-07 22:41:47 +10:00
Loic Blot fd70f4f2f0 Replace std::list by std::vector into ClientMap::updateDrawList, Map::timerUpdate and ServerMap::save(). 
This will speedup the loop reading into those functions

Loic Blot 80a7408e4d Fix a crash (assert) when client set serial version < 24 in INIT 
When SER_FMT_VER_LOWEST is set to zero, then the test is stupid in INIT because all client works. In mapblock we check if client's serialization version is < 24, but if client sent serialization version < 24 (15 for example) the server set it and tried to send nodes, then BOOM

To resolve the problem:
* Create a different CLIENT_MIN_VERSION to handle this problem
* Remove the exception
* Use an assert in case of bad developer code
