*	main.cpp rework * Move ClientLauncher class to a dedicated file * ↵	Loic Blot	2015-02-12
| | | |	ClientLauncher now owns print_video_modes and speed_tests functions (they are only called by him) * Move GameParams to shared/gameparams.h because it's shared between server and client and launcher need to know it * Move InputHandlers class to client/inputhandler.h * Cleanup includes
*	Network Layer 7 rework (Packet handling)	Loic Blot	2015-02-10
| | | | | | | | | | | | | |	* Move networkcode to a dedicated directory * Rename clientserver.h to network/networkprotocol.h (Better name) and sanitize some includes * Create object NetworkPacket * It stores command (opcode) and data separated * It also stores peer_id * Data reading can be done by using a streaming interface * Change packet routing analysis * Remove old conditional analysis * Now uses function pointed analysis and add connection state ({Client,Server}::handlers) * Connection state permit to categorize condition to handle before analyze packets * Create a handler for depreciated messages, instead of duplicating code
*	Create minidump on fatal Win32 exceptions	kwolekr	2015-02-02

*	Fix all warnings and remove -Wno-unused-but-set cflag	kwolekr	2015-01-18
|
*	Add SemiDebug (-O1 with debug symbols) build mode and do not optimize Debug ↵	kwolekr	2015-01-18
| | | | | | |	at all Add -Wall to Debug modes for all compilers and -Wabi for non-MSVC Use /Ox for MSVC Release mode (potentially higher optimization than /O2)
*	Revert "Fix bug in debug build"	kwolekr	2015-01-18
| | | |	This reverts commit 839c4a99cddcacdc19dee42286b7029c4c1e7800.

*	Fix compiling if no endian.h found	Pavel Puchkin	2014-11-22
| | | | | | | | | | | |	f7d6509 introduces error when no endian.h found in the system. Since "CHECK_INCLUDE_FILE" returns empty string instead of "0", when "cmake_config.h" is generated it has "#define CMAKE_HAVE_ENDIAN_H " line. Later we have "#define HAVE_ENDIAN_H CMAKE_HAVE_ENDIAN_H" in the "config.h", an thus "HAVE_ENDIAN_H" is also empty sting. Because of this, "#if HAVE_ENDIAN_H" is incorrect preprocessor directive.

*	serialize.h: use machine native byte swapping if available, fall-back to ↵	Rafael Reilova	2014-11-21
| | | | | | | | | | | | | | | | | | | | |	previous generic method if not (supported for GCC using endian.h, detection done in cmake) write/readARGB8() - just write 32-bit color in one op, instead of 4 1-byte ops cleanup: removed unneeded buffer init for some serialize-out functions use a #define for the fixed point factor in read/writeF1000() nodemetadata.cpp, nodetimer.cpp optimzation: simpler deserialize node position method staticobject.cpp: cleanup: use util/serialize.h inlines instead of its own de/serialization serialize.cpp: minor optimization/cleanup: avoid generation of unneeded string temporary CMakeLists.txt, cmake_config.h.in: detection of endian.h config.h: added HAVE_ENDIAN_H Commits due to feedback squashed Signed-off-by: Craig Robbins <kde.psych@gmail.com>
*	Implement WieldMeshSceneNode which improves wield mesh rendering	Kahrl	2014-11-08
| | | | | | | | | | | | |	- Don't create and cache an extruded mesh for every (non-node) item. Instead use a single one per image resolution. - For cubic nodes reuse a single wield mesh too - Improve lighting of the wielded item - Increase far value of wield mesh scene camera, fixes #1770 - Also includes some minor refactorings of Camera and GenericCAO.

*	BUILD: prefer pkg-config for freetype2 detection	hasufell	2014-01-05
| | | | | | | | | | |	This can solve numerous problems such as: http://www.cmake.org/Bug/view.php?id=13959 http://www.cmake.org/Bug/view.php?id=14601 If pkg-config or freetype2.pc is not found, then fall back to the FindFreetype.cmake module logic. Restrict to UNIX since I only tested it here.
*	Add option to link to OpenGL ES, fixes #1051	Sfan5	2014-01-05
|
*	Rewrite client media download and support hash-based remote download	Kahrl	2013-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |	Move most of the media-related code in client.cpp into a new class ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other things, this class does the following things: - Download [remote_server][sha1] instead of [remote_server][name]. This is to support servers that provide the same file name with different contents. - Initially fetch [remote_server]index.mth. This file should follow the Minetest Hashset format (currently version 1) and contain a list of SHA1 hashes that exist on the server. - The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is requested, so servers can optionally narrow down the list to the needs of the client. - If index.mth is missing (HTTP response code 404), we enter compat mode, fetching [remote_server][name] as before this commit. - remote_server can now contain multiple servers, separated by commas. The downloader code attempts to split requests between the different servers, as permitted by each server's index.mth. If one server claims to have a file but actually doesn't (or something fails), we ask a different server that also claims to have it. - As before, when none of the remote servers provide a particular file, we download it via the conventional method, i.e. using the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA. - Bugfix: Every downloaded file's SHA1 is now verified against the SHA1 announced by the minetest server (before loading it and inserting it into the file cache). - Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all media. This should fix #863.
*	Implement httpfetch module and initialize it from main()	Kahrl	2013-12-13
| | | | | | | |	Add curl_parallel_limit setting that will replace media_fetch_threads in a later commit. Fix a typo in MutexedQueue::pop_back() that made it impossible to compile code that used this function. (Noticed this while implementing httpfetch.)
*	Fix win32/msvc i18n (quite UGLY version, blame Microsoft)	sapier	2013-11-11
|
*	Pass VERSION_EXTRA to GenerateVersion.cmake	Kahrl	2013-09-29
|
*	Show git hash in version string at top left corner of window	Kahrl	2013-09-28
|
*	Add curl, freetype and luaJIT to CMAKE_BUILD_INFO	PilzAdam	2013-09-28
|
*	Always use builtin JThread library	kwolekr	2013-09-15
