- Empty buffers using `io_flush` before calling the OS function for
syncing the file to disk.
- Fix error return of `io_sync` on Windows.
- Don't indiscriminately flush all files on close.
- Add a test that `io_sync` can return without error.
I'm wondering if this helps. Overhead exists, but is not that much (on
my system): 333 ms for initialization instead of 311 ms
If we only want to do this for files written to, then we need to keep
track of how the file was opened.

- Haiku is Unix-like, but it still doesn't use libnotify.
- Haiku comes with its own sets of definitions for certain long variables.
There's still a problem revolving around the variables, but I removed a
duplicate, conflicting definition on the Haiku platform.
- Changed some definition-related logic in detect.h, because the gcc compiler
in Haiku (version 8.3.0) complained about duplicate definitions. I chose to
use 'unknown' rather than an empty string on one occasion.
- Changed size of m_aLastSoundPlayed[CHAT_NUM] in

in Haiku.
4111: Fix filesystem/IO with unicode filenames on windows r=def- a=Robyt3
It was previously not possible to load a map or really any file with a filename containing unicode, e.g. german umlauts.
Now all filenames are converted from multibyte to widechar on windows, and the correct functions and structs (with the `W` suffix) are used consistently.
Some changes are made to synchronize ddnet's implementation with upstream (once https://github.com/teeworlds/teeworlds/pull/2936 has been merged there):
- The unused and not working `IOFLAG_RANDOM` is removed (on upstream ddnet's `IOFLAG_APPEND` is added instead).
- The `fs_listdir_info` function is renamed to `fs_listdir_fileinfo` and now using the parameter object `CFsFileInfo` that contains the filename, modified date and creation date, making it easier to add more properties in the future. `FS_LISTDIR_INFO_CALLBACK` is renamed to `FS_LISTDIR_CALLBACK_FILEINFO`.

3798: Add GLES support r=def- a=Jupeyy
I know i *****ed up, that i didnt move the files in a different commit, but when i noticed it was already too late.
Its mostly disabling stuff that GLES doesn't support. Global LOD bias or glOrtho for examlpe.
~***Strong note***:
This will move ALL linux implementation to GLES instead of GL, since GLES is supported by X11 and wayland, we probably want some testing for this.
This also means, that the default for Linux gets GLES 3.0 which is equivalent to OpenGL 3.3, not OpenGL 3.0!!!~
~If you wonder "why":
Gles just works differently to OGL, it knows about all functions that exists, and e.g. doesn't require GLEW at all, but that also means, that GLES does NOT work while we use OGL, because GLEW would kill GLES.~
GLEW in EGL mode works fine with wayland, just requires X11 to use EGL too(SDL_VIDEO_X11_FORCE_EGL)
_Additionally, for GLES only, only 3.0 and 1.0 context are supported._(doesn't matter anymore for linux)
probably fixes:
~not_really_fixes #3797~
fixes#2885
And would also allow android support, if i ever get these build scripts upto date, or smby is interested into fixing them for me :D

3779: Copied Teeworld patches for the Haiku operating system r=def- a=panos
I initiated a port of ddnet and received a lot of help from the IRC in order to do so as seen in #2986. Unfortunately, my efforts went stale after one point. Fortunately, however, @threedeyes released a [set of patches for Teeworlds](2ea72967cd/games-action/teeworlds/patches/teeworlds-0.7.5.patchset). I decided to take down my repository with my own work and attempt to port Gerasim's work, which includes code for setting the directories that ddnet should use the same way one would do so in a Mac OS X-system in `src/base/system.c`, which was precisely the part where I got stuck in on my first attempt.
The changes have not been tested thoroughly yet and were the result of methodic copying and pasting.

Quoting the man page of vsnprintf:
RETURN VALUE
Upon successful return, these functions return the number of characters printed
(excluding the null byte used to end output to strings).
The functions snprintf() and vsnprintf() do not write more than size bytes (including
the terminating null byte ('\0')). If the output was truncated due to this limit,
then the return value is the number of characters (excluding the terminating null
byte) which would have been written to the final string if enough space had been
available. Thus, a return value of size or more means that the output was truncated.
(See also below under NOTES.)
If an output error is encountered, a negative value is returned.
[...]
The glibc implementation of the functions snprintf() and vsnprintf() conforms to the
C99 standard, that is, behaves as described above, since glibc version 2.1. Until
glibc 2.0.6, they would return -1 when the output was truncated.
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.
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`.
This makes `LATIN SMALL LETTER L` confusable with `LATIN SMALL LETTER I`
because `CYRILLIC SMALL LETTER PALOCHKA` "ӏ" (mapping to i) wasn't
confusable with `LATIN SMALL LETTER L` "l" (mapping to l) before.
Also add tests for `str_utf8_comp_confusable`.
`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
1055: Keep track of lost frames and update time r=heinrich5991 a=Jupeyy
The problem a friend was occuring was, that on a fresh Windows install settings like cl_refresh_rate are set to 480.
Since the render calls take longer time than no render calls, it happened that client was sleeping on one update cycle and then took to long in another, where it called the render functions, leeding to less FPS than the cl_refresh_rate. this caused mouse lags and rarely frame drops.
another thing is, that select on Windows is non microsecond accurate, or just often returns too early, which caused that the refresh rate is much too high, or even ignored, (probably windows can only sleep on milliseconds, or again, is extremly inaccurate).
Another things on windows is that time_freq might be a "very odd" number ^^
i mean like on unix it's one microsecond (1,000,000 = 1s), but on windows the time_freq depends on the CPU leading to inaccurate calculation of the sleep time and render time.
This wasn't insanly huge issue, but probably skipped a few microseconds here and there.
This fix should stabilize the frames. I'd like to hear your opinion on this tho.
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

957: Add manual locking to `ASYNCIO` for transacted writes r=Learath2 a=heinrich5991
Previously, e. g. it was possible that newlines are separated from the
printed line in `logger_file`.
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.
Also annotate `dbg_msg`, `str_format` and `str_timestamp_ex` so that the
compiler can determine whether the format strings are correct.
Fix the compiler warnings generated by these extra warnings -- some of
them were security issues.
This also fixes a couple of potential buffer overflows. The affected
code is still buggy (doesn't do the right thing on potential buffer
overflow), but at least it won't result in crashes/out of bound writes
anymore.
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.
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.
This not only makes `str_utf8_decode` a compliant parser, but also fixes an
issue where overlong encodings led to undetected line breaks.
Implemented as per https://encoding.spec.whatwg.org/#utf-8-decoder.
Audited the following files, checking whether the new semantics work with the
existing code:
- src/base/system.c
- src/engine/client/text.cpp
- src/game/client/components/chat.cpp
- src/game/server/gamecontext.cpp
They all check whether the string is at its end separately.
