Number of minutes of active racing time before being asked to confirm
disconnecting, disconnecting dummy or quitting through GUI. Defaults to
20 minutes, -1 to disable, 0 to always enable.
Also removed confirmation to quit when in main menu, except when having
an unsaved map in editor.
Spectate and kill should already be safe thanks to server-side kill
protection.
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.
1157: Add a way to call for external moderator help r=Learath2 a=heinrich5991
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.
1160: Fix warning about incompatible function pointers r=Learath2 a=heinrich5991
This comes at the cost of one allocation per started thread. This should
be okay because we're about to invoke a syscall anyway.

Supersedes #1129.
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.
869: Complete rework of the ghost and race recorder r=Learath2 a=Redix
This PR fixes a lot of issues with the ghost and race recorder, introduces a new ghost file format and implements some pretty useful features.
**A quick overview:**
- When you cross the start line multiple times, both (ghost and recorder) will only restart if it is a non-solo server
- If available, both will use the race timer to recognize the start instead of searching for the start line
- Fastcap support for both
- The recorder immediately starts when the Tee spawns, so the preparation steps (which are quite important for speedruns) will be included in the demo. If you do not cross the start-line within 20 seconds, it will stop the demo until you really start.
- Better ghost menu (colors, reloading, deleting and saving ghosts)
- The ghosts are more resistant against lags (old ones were sometimes completely useless due to small lags)
- New ghosts files are significantly smaller
- Cleanup, bugfixes..
**About the new ghost format (version 4/5):**
This format is used by Teerace for over a year now. The code for handling the binary files was moved to the engine. It includes an auto updater which creates a backup of all ghosts and converts them to the new format afterwards. The major differences from the format used by DDNet right now (version 2), are the ability to store multiple types of data, the usage of delta-encoding and a more portable header.
For whatever reason, the ghost stores values for every predicted tick, but without tick information, so lost snapshots can make them unusable. The new code uses the original values from the snapshots including ticks but it can also handle the old ones without. Since hardly any server uses the high bandwidth option this practically reduces the file size.
Like the demo recorder the ghost recorder directly stores the data to a file (every 50 snapshots) instead of writing the whole file at the end of the race. Indeed this can be changed with only a few lines if the old behavior is preferred.
The updater can handle version 2 (DDNet) and 3 (old teerace format, only slightly different from version 2) files. The updating already happens when the files are scanned for generating the list in the menu and not only when you activate them. The change from version 4 to 5 was only needed due to a bug in the implementation, the ghost loader can read both.
Some numbers about the file size: (map: hotrun, both about 30 seconds)
- Old ghost: 30.4 kB (converted: 10.7 kB)
- New ghost: 5.4 kB
**One thing about the race recorder:**
The old implementation compared the new file only with the first file it found for the particular map. The new one compares with all related demos and deletes them possibly, so that only the best demo is left. Since DDNet can also store the demos without name, this might also delete demos from other players, that you might have in your directory.
To prevent this I at least check whether the demo contains the player name if `cl_demo_name` is on.
In my opinion the better solution would be to remove `cl_demo_name` and always use the player name.
- 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 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 way, servers can no longer hijack the timeout codes of clients.
Timeout codes are generated from md5(seed + dummy + server address).
If `cl_timeout_seed` is set to the empty string, the old config options
are used instead.
