SHA256 was chosen because it is reasonably standard, the file names
don't explode in length (this rules out SHA512) and it is supported by
basically all versions of OpenSSL (this rules out SHA512/256 and SHA3).
The protocol is changed in a backward compatible way: The supporting
server sends the SHA256 corresponding to the map in the `MAP_DETAILS`
message prior to sending the `MAP_CHANGE` message. The client saves the
SHA256 obtained from the `MAP_DETAILS` message until the next
`MAP_CHANGE` message.
For servers not supporting this protocol, the client falls back to
simply opening maps like in the previous scheme.
Remove the `map_version` tool, it is not being used and would have been
a little bit effort to update.
Use the OpenSSL implementation of SHA256 if it is supported, otherwise
fall back to a public domain one.
Fix#1127.
This uses the Unicode confusable data together with judging how close
two strings are by using the Levenshtein distance.
Adds the commands `name_ban`, `name_unban` and `name_bans`. Kicks
players who join using a banned name and doesn't allow ingame players to
change their names to the banned ones.
The engine now takes `std::shared_ptr<IJob>`, this will ensure the
appropriate lifetime of the given parameters, it also allows for proper
destruction. Remove the now obsolete `IFetcher` interface and `CFetcher`
class.
Also adds some locks to `CUpdater`, previously it didn't have any locks
at all.
teehistorian records all inputs from the players as well as the player
positions in each tick. It stores this info in a highly compressible
output format (I've achived 5x compression using xz or bz2).
- Single json file containing all information for the client
- Fetched from https://info.ddnet.tw/info?name=deen
- Replaces versionsrv, news, ddnet-maps.json and ddnet-ranks.json
- Servers are sorted by most popular ones for respective player
- Always stays < 100 ms response time, compared to occasional 50 s for
old ddnet-ranks.json
This uses an extended protocol message to signal that rcon
authentication might require a username, allowing the client to enable
the username prompt.
Add a forgotten logout on key update
This system can easily be extended by independent authors without
collisions, something the old system with plain increasing integers did
not allow.
Do this by utilizing the previously unused message code `NETMSG_NULL`
which has a value of 0.
This works for engine and game messages, snapshot items and events.
This means that we have a reliable and fast way to query for extended info,
while also not wasting network bandwidth.
The protocol is designed to be extensible, there's four bytes space for
encoding more request types (currently zeroed), and there's one string in each
response packet and one string for each player available (currently the empty
string).
The protocol itself has no problems with more than 64 players, although the
current client implementation will drop the player info after the 64th player,
because it uses a static array for storage.
Also fixes#130, the player list is just sorted each time new player info
arrives.
This lets 0.6.4 clients connect to DDNet servers again. Instead of doing
our own resend logic, just always send `sv_map_window` packets ahead and
let the Teeworlds network deal with possible resends.
reading from and writing to several different servers is now possible
TODO:
-handle Exceptions properly (try another sqlserver)
-if everything fails while writing write the insert to a file
