We allocated 512 bytes to dump up to 32 data bytes in a hex form.
According to the str_hex() implementation, we need three bytes per the
source data byte (a byte is represented as a two-digit hexadecimal number
with appended space char) plus the null-termination.
We actually could re-use the last space char for the null, but it is not
implemented in str_hex(). Keep this logic as-is.
The stack-allocated buffer size reduced from 512 to 97 bytes.
The current NETMSG_PING and NETMSG_PING_REPLY messages suffer from the
fact that you cannot know whether a given NETMSG_PING_REPLY is from your
NETMSG_PING.

3568: Get rid of the MySQL C++ connector as a dependency and disable C++ exceptions r=Learath2 a=heinrich5991
We now use the C API directly. This has the advantage of using one
obscure dependency less, as the C++ connector also used the C API.
Also remove exceptions from database code.
The equivalent code with return codes is a human-assisted mechanical
translation of the old code, no attempts to improve correctness were
made.
This allows us to enable the -fno-exceptions flag.

Fixes#2271
Note that the server exits when creating tables failed. Since the tables are created by default, it has to be disabled explicitly (e.g. `add_sqlserver r teeworlds record teeworlds PASSWORD "localhost" 3306 0`) if the servers should start even when the database connection fails.

OK, maybe not actually remove because it is kept for fallback when the
new method isn't available.
The whole gametype parsing business had the same downsides as user agent
parsing on the web, hence I removed it while keeping behavior the same.
This allows servers to explicitly opt in or out of certain bug
workarounds and other client behavior. This increases the complexity of
different configurations that are available in the client (which is a
bad thing).

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 is done by HTTP POSTing to a location specified by
`sv_modhelp_url`. We also provide a `src/modhelp/server.py` which can
use theses POSTs to forward them to Discord servers.
The POST contains a JSON object payload, with the keys `"port"` which
contains the server port, `"player_id"` which contains the calling
player's client ID, `"player_name"` which contains the calling player's
nick and `"message"` which is the user-specified message.
Make JSON-escaping function public, add tests and fix bugs uncovered by
these tests.
Supersedes #1129.
Replace `mem_free` by `free`, and `mem_alloc` by `malloc` or `calloc`
(the latter one being used to allocate a zeroed array of elements,
sometimes, this makes a call to `mem_zero` superfluous).
This results in having to remove `mem_stats` which previously recorded
the number of allocations and their size that the Teeworlds code did
directly.
Remove OOM handling in `src/game/client/components/binds.cpp`.
Remove needless copying in the CSV code in
`src/game/client/components/statboard.cpp`.
`str_utf8_isspace` now returns true if the passed code point renders as
a space, instead of when not.
Add `str_utf8_trim_right`, use this function and
`str_utf8_skip_whitespaces` in the server.
Add tests for the three functions
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.
It was horribly broken before. :) Only the first password set via
`sv_rcon*_password` worked, and that only due to a bug in `AddHashKey`
-- `AddHashKey` incorrectly assumed that only key slots greater than 0
are valid, but 0 is valid too.
Fix default passwords on password removal, fix no admin password being
generated if you only had `sv_rcon_mod_password` or
`sv_rcon_helper_password` set. Add an assert that would have caught our
mistake.
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.
See UTS#39 "Unicode Security Mechanisms":
http://www.unicode.org/reports/tr39/
This means that characters with accents or other things around them are
now considered the confusable with the base character.
Fixes#557. Fixes#575.
CSqlData is const for threadfunctions now to avoid modification from
within the threadfunctions as these might be called several times.
Previously this was a problem as ClearString could possibily be applied
multiple times to the same string.
To solve this the class CSqlString has been added. This class takes a
const char* and copies it. Additionally a clearstring is created from
the given const char*. This enables access to the original as well as
the cleared string safe for sql-statements.
sql_string_helpers got an own source file now.
A crashbug from CSqlServer has been fixed (pointer has not been set
back to 0)
