| | | |	* Fix Wstringop-overflow warning from util/srp.cpp
*	Modernize source code: last part (#6285)	Loïc Blot	2017-08-20
| | | | | | | | | | |	* Modernize source code: last par * Use empty when needed * Use emplace_back instead of push_back when needed * For range-based loops * Initializers fixes * constructors, destructors default * c++ C stl includes
*	Code modernization: subfolders (#6283)	Loïc Blot	2017-08-19
| | | | | | | | | | | | |	* Code modernization: subfolders Modernize various code on subfolders client, network, script, threading, unittests, util * empty function * default constructor/destructor * for range-based loops * use emplace_back instead of push_back * C++ STL header style * Make connection.cpp readable in a pointed place + typo
*	Remove superfluous pointer null checks	QrchackOfficial	2017-06-10

*	Update embedded jsoncpp from unk version to 0.10.6 + move libs to lib/ ↵	Loïc Blot	2017-04-02
| | | | | | | | | | | | | | | |	instead of src/ (#5473) * Update embedded jsoncpp from unk version to 0.10.6 0.10.6 is last release without c++11 * Make jsoncpp more compliant with its amalgamate Jsoncpp cpp file should be upper, make the library like it does in amalgamate * Reorganization: move minetest embedded libs outside of source tree to /lib * Fix a dead grep in LINT
*	couple of memory leaks fixes.	David Carlier	2016-08-10

| | | |	There it isn't needed.
*	Fix some SRP issues	est31	2015-09-30
| | | | |	-> Remove memory allocation bugs -> Merge changes from upstream, enabling customizeable memory allocation
*	Initialize random for verification key generation too	est31	2015-08-06
|
*	Check output of mpz_set_str and fix leak on error condition	est31	2015-07-24
| | | |	Also add static identifier as upstream did
*	Remove some old dead code. Fix some Clang warnings in SRP (ng->N... will	Loic Blot	2015-07-24
| | | |	always evaluate to true.
*	Make early protocol auth mechanism generic, and add SRP	est31	2015-05-11
	Adds everything needed for SRP (and everything works too), but still deactivated, as protocol v25 init packets aren't final yet. Can be activated by changing the LATEST_PROTOCOL_VERSION header to 25 inside networkprotocol.h.
