* Replace various std::map with UNORDERED_MAP + various cleanupsLoic Blot2016-10-05
| | | | | | | | | | | | This is part 2 for 5f084cd98d7b3326b51320455364337539710efd Other improvements: * Use the defined ItemGroupList when used * make Client::checkPrivilege const * inline some trivial functions * Add ActiveObjectMap typedef * Add SettingsEntries typedef
* Client: disable pre v25 init sending by defaultest312016-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disable the ability to connect to old servers by default to improve password security. If people still want to connect to old (0.4.12 and earlier) servers, they can flip the send_pre_v25_init setting. Add the ability to detect if we've tried to connect to a server which only supports the pre v25 init protocol, and show an apropriate error message. Most times the error will already be catched at the serverlist level, the detection mechanism only acts as last resort, because the "Connection timed out" error message that would be shown otherwise would be very confusing. Automatic "fixing" of this condition is not desired, as it would allow for downgrade attacks. As already 161 of the 167 servers on the serverlist support the new srp based auth protocol (> 96%), the breakage should be minimal. Follow up of commit af30183124d40a969040d7de4b3a487feec466e4 "Add option to not send pre v25 init packet" Also change the pessimistic assumption of masterlist server versions to optimistic, in order to avoid buggy behaviour (favourites not in the serverlist would be denied to connect to, etc).
* Particles: Add option to remove particles on collisionAuke Kok2016-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | Adds the particle option `collision_removal = bool` Some particles are hard to use right now since they either go through solid blocks (without collision detection), and with collision detection enabled they (e.g. raindrops) would just stop dead on the floor and sit there until they expire, or worse, scrape along a wall or ceiling. We can solve the problem by adding a boolean flag that tells the particle to be removed if it ever collides with something. This will make it easier to add rain that doesn't fall through your roof or stick on the top of it. Or clouds and smoke that don't go through trees. Particles that collide with this flag are marked expired unconditionally, causing them to be treated like normal expired particles and cleaned up normally. Documentation is adjusted accordingly. An added bonus of this patch is that particles can potentially collide many times with nodes, and this reduces the amount of collisions to 1 (max), which may end up reducing particle load on the client.

* 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.

* 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.
* Optional reconnect functionalityest312015-07-23
| | | | | | Enable the server to request the client to reconnect. This can be done with the now extended minetest.request_shutdown([reason], [reconnect]) setting.
* Client: better m_proto_ver initialisationest312015-07-07
| | | | | | | | Previously, m_proto_ver was set to the serialisation version inside the legacy init packet. Now, if the server doesn't send a protocol version (protocols < 25), we set m_proto_ver to some value < 25 and > 0.

* Make early protocol auth mechanism generic, and add SRPest312015-05-11
| | | | | | | 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.

* Refactor around translatePasswordest312015-04-17
| | | | | | | Change types for passed password from wstring to string, which removes converting back and forth in most cases. Move the narrow_to_wide conversion, where its neccessary, closer to irrlicht. Remove trailing spaces in guiPasswordChange.cpp. Make parameters for translatePassword passed as const reference.
* Connection::Receive(): receive Network Packet instead of SharedBuffer<u8>.Loic Blot2015-03-31
| | | | | | | Because we get a Buffer<u8> from ConnectionEvent, don't convert it to SharedBuffer<u8> and return it to Server/Client::Receive which will convert it to NetworkPacket Instead, put the Buffer<u8> directly to NetworkPacket and return it to packet processing This remove a long existing memory copy Also check the packet size directly into Connection::Receive instead of packet processing
* Change error_message from wstring to stringShadowNinja2015-03-27
| | | | This removes a lot of narrow/wide conversions where a wide string was never used.
