Switch to using the Windows-specific `HANDLE` and Windows API functions instead of `FILE *` and standard library functions in all Windows IO function implementations.
Using `CreateFileW` instead of `_wfsopen` to open files is necessary, as only `CreateFileW` allows specifying all necessary sharing flags. The sharing flags `FILE_SHARE_READ` and `FILE_SHARE_WRITE` were previously already specified by using `_SH_DENYNO` with `_wfsopen`, but `FILE_SHARE_DELETE` can only be set when using `CreateFileW`. The flags are necessary so files which are in use by the game can still be opened by other processes. In particular, `FILE_SHARE_DELETE` allows deleting/renaming of open files, which was previously not possible. This was causing the smart editor saving process that renames files to fail if a map file is currently in use.
Because `CreateFileW` returns a `HANDLE` instead of a `FILE *` we have to use the `HANDLE`-based Windows IO functions everywhere.
See: https://devblogs.microsoft.com/oldnewthing/20211022-00/?p=105822Closes#6922.
`stdout_output_level` for printing to stdout, `console_output_level` for
printing to local console and remote console and `loglevel` for the log
file.
Keep the old log level filters 0 for info and more severe, 1 for debug
and more severe and 2 for trace and more severe, introducing -1 for
warn, and -2 for error. -3 will show no log messages at all.
Port map and editor support for `CURVETYPE_BEZIER` from upstream, i.e. support bezier curves with configurable in- and out-tangents for every envelope point.
The in- and out-tangents are represented by triangles and can be dragged in the envelope editor like the envelope points.
Support reading and writing the bezier information as a separate UUID-based map item. If the bezier information is not found, bezier will default to linear behavior. Old clients will still be able to read the new maps and ignore the unknown map item. The unknown curvetype will also be handled as linear by old clients.
Allow reading upstream maps that use `CMapItemEnvelope` version 3. On upstream, a different struct is used to store all envelope points including bezier information, which broke compatibility to old clients.
Fix holding Ctrl for slow envelope point editing not working for vertical movement.
Highlight the currently selected element (envelope point or bezier tangent marker) which is being used with the value/time edit boxes.
Hide the value/time edit boxes when no element is selected.
Add optional `end` output parameter to `str_utf8_find_nocase` which is set to a pointer into the haystack after the matched string.
This is necessary because there are pairs of matching upper case and lower case Unicode characters with different byte length (e.g. both `I` and `İ` map to `i`), so the byte length of the string matched in the haystack may not be identical to the length of the needle string.
6755: Remove individual RGBA sliders from editor color picker, add shift+rightclick/leftclick to copy/paste color in editor r=Jupeyy a=Robyt3
Remove the individual RGBA sliders for editor color pickers and only show one button that opens the color picker popup instead.
Decrease size of layer and point popups that previously had color properties which need less space now.
Support shift-rightclicking color picker buttons to copy the color to the clipboard in RRGGBBAA hex format.
Support shift-leftclicking color picker buttons to paste a color from the clipboard in RGB, RGBA, RRGGBB or RRGGBBAA format with optional leading `#` or `$`.

Suggested by `@HiRavie` in https://github.com/ddnet/ddnet/pull/6743#issuecomment-1593886873, though it was easier and also looks better to me when the color picker button has exactly the same size as the other value selectors.

To convert between UTF-8 encoded strings and wide character strings used with the Windows API.
The functions use `std::wstring` and `std::string`, to simplify the usage and support arguments with arbitrary length.
Also add some tests for the functions.
Port the line input (UI edit boxes, chat, console) and Input Method Editor (IME) support from upstream. Closes#4397.
General
------------------------------
Fix issues with the text input. Closes#4346. Closes#4524.
Word skipping (when holding Ctrl) is overhauled to be consistent with the Windows / Firefox experience that I took as reference.
Improve usability by not blinking (i.e. always rendering) the caret shortly after is has been moved.
UI text input
------------------------------
Fix inconsistent mouse-based left and right scrolling (closes#4347).
Support smooth left and right scrolling.
Chat
------------------------------
Support keyboard-based text selection of the chat input.
Mouse-based selection could be support in the future when we decide to add something like an ingame UI cursor.
Support smooth up and down scrolling of the chat input, removing the old hack that offsets the input string to simulate scrolling.
Console
------------------------------
Also support mouse-based text selection of the command input.
Only text from either the command input or the console log can be selected at the same time. This ensures that Ctrl+C will always copy the text that is currently visually selected in the console.
Check for Ctrl+C input event in event handler instead of in render function, to hopefully fix the issue that copying does not work sometimes (closes#5974 until further notice).
When Ctrl+C is used to copy text from the console log, the selection is cleared. This should make it more clear when text was copied from the log.
Fix an issue that was preventing the console log selection from being cleared, when all log lines are selected.
Remove Ctrl+A/E hotkeys that move cursor to beginning/end respectively. Ctrl+A now selectes all text like for all other inputs. Home and End keys can still be used to go the beginning and end.
Remove Ctrl+U/K hotkeys that clear everything before/after the cursor respectively. Hold shift and use Home/End to select everything instead.
IME support
------------------------------
Render list of IME candidates in the client on Windows, so the candidate list can also be viewed in fullscreen mode. There is no API available to retrieve a candidate list on the other operating systems.
Improve composition rendering by underlining the composition text instead of putting it in square brackets.
Track active input globally to properly activate and deactivate IME through the SDL functions.
Closes#1030. Closes#1008.
Password rendering
------------------------------
Fix rendering of passwords containing unicode. Instead of rendering one star character for each UTF-8 `char`, render on star for every unicode codepoint.
Show the composition text also for passwords. Without seeing the composition text it's hard to type a password containing those characters. The candidate window exposes the composition anyway. If you don't want to expose your password this way, e.g. while streaming, you could:
1. Use a latin password and switch off the IME for the password input with the IME hotkey.
2. Blank your screen with an external program while you are streaming and entering passwords.
3. Use binds to authenticate in rcon or to set the server browser password.
Refactoring
------------------------------
Move all text input logic and general rendering to `CLineInput`.
A `CLineInput` is associated with a particular `char` buffer given as a pointer either in the constructor or with `SetBuffer`. The maximum byte size of the buffer must also be specified. The maximum length in unicode codepoints can also be specified separately (e.g. on upstream, name are limited by the number of unicode codepoints instead).
Add `CLineInputBuffered`, which is a `CLineInput` that own a `char` buffer of a fixed size, which is specified as a template argument. As `CLineInput` does not own a buffer anymore, this reduces duplicate code for line inputs that need their own buffer.
Add `CLineInputNumber` which has additional convenience functions to consider the text as an `int` or `float`, to reduce duplicate code in those cases. In the future we could also add an input filter function so that only numbers can be entered in the number input.
Add `CLineInput::SetClipboardLineCallback` to handle the case that multiple lines of text are pasted into a lineinput. This reduces duplicate code, as this behavior was previously implemented separately for chat and console. The behavior is also fixed to be consistent with the console on Windows, so the first line being pasted edits the current input text and then sends it instead of being sent on its own without the existing input text.
Add `CalcFontSizeAndBoundingBox` to UI to reduce duplicate code. Expose `CalcAlignedCursorPos` as static member function to reuse it for line input.
Dispatch input events to UI inputs through the event handler instead of storing them in a duplicate buffer.
Use `size_t` for line input cursor position, length etc. and for `str_utf8_stats`.
Add `IButtonColorFunction` to UI to describe a functions that defines colors for the Default, Active and Hovered states of UI elements. Add some default button color functions. Use button color function to reduce duplicate code in scrollbar rendering.
Use `vec2` instead of two `floats` to represent the mouse positions in the text renderer.
Remove `CaretPosition` again, as it does not calculate the correct Y position near line breaks due to the wrapping being different when not rendering the entire string. Instead, calculate the exact caret position when rending a text container and store the caret position in the text cursor for later use.
IME usage guide (Windows)
------------------------------
1. Install the respective language and the Microsoft-IME keyboard (e.g. for Chinese, Japanese or Korean).
2. Launch the game (or a text editor to first try out the IME). Note that Windows may track the input language separately for every application. You can change this in the Windows input settings so the input language is changed globally.
2. Switch the input language using the hotkey Windows+Space or another hotkey that you configured in the Windows input settings (Alt+Shift is the default, but you should consider disabling it, to avoid accidentally changing the input language while playing).
3. Switch from Latin/English input mode to the respective asian input mode.
- Chinese: Use Ctrl+Space to switch between English and Chinese input mode. You can change this hotkey in the IME's settings.
- Japanese: Use Ctrl+Space to switch between Alphanumeric and Hiragana/Katakana input mode. You can change this hotkey in the IME's settings.
- Korean: Use Right Alt to switch between English and Hangul input mode. You cannot change this hotkey as of yet.
- Note that the input mode is also tracked per application, but there is no setting to change this behavior as far as I know, so you'll need to switch for every application separately.
4. Start typing. The underlined text is the current composition text. While a composition is active, you can only edit the composition text. Confirm the composition with Space or by selecting a candidate from the candidate list with the arrow keys. Cancel the composition with Escape or by using Backspace to delete the composition text. Note that not all languages offer a candidate list.
SDL version-specific issues
------------------------------
- 2.26.5, 2.24.2, 2.0.22: IME candidates work. But there are minor bugs when moving the composition cursor.
- 2.0.18, 2.0.20: IME candidates work.
- 2.0.16 (our current version): IME candidates cannot be determined with Windows API. Windows tries to draw the composition window like before, so this does not work in fullscreen mode.
- 2.0.8 (upstream 0.7): IME candidates work. But this SDL version is too old for us.

Reduces duplicate code. This also ensures that the log messages are properly zero-terminated and that they do not end with truncated unicode characters.
So the string formatting can be reused in other places. Passing variadic arguments directly to another function is not possible.
The function must have a different name, as overloading `str_format` would cause the wrong function to be called when passing the `va_list`. The same naming with suffix `_v` is used for the logging functions.
Add `random_float(float min, float max)` to generate a random `float` between `min` and `max`.
Add `random_float(float max)` to generate a random `float` between `0.0f` and `max`.
Replace existing `RandomDir` with this function. This function was biased towards the corners, as it first generates a random `vec2` with `x` and `y` in `[-0.5f;0.5f]` and then normalizes it, which doesn't result in a uniform distribution of directions. Now the random direction is generated by taking a random angle and then converting it to a direction which is per definition already normalized.
To generate a random angle in the range `[0.0f;2.0f * pi[`. This ensures that the random angle cannot be `2.0f * pi`, which would be identical to the angle `0.0f` and therefore cause the random angle to be less uniformly selected.
Note that this first casts `RAND_MAX` to a `float` and then uses `std::nextafter` to get the next larger `float`. Using `RAND_MAX + 1` would cause an integer overflow on systems where `RAND_MAX == INT_MAX` (e.g. Ubuntu and macOS).
6324: Optimize client ids map update r=def- a=0xfaulty
I have launched support for 128 players in testing mode on my server, it's means it's time for another step in this direction here. Perhaps not all changes will be clear, I am ready to answer/discuss them as usual. Let me know if I forgot or didn't take anything into account.

6345: Set constant and uniform names for the server and client CMake targets r=def- a=Kaffeine
This MR set the server and client CMake target names to `game-server` and `game-client` which are uniform with other targets such as `engine-gfx`, `engine-shared`, and `game-shared`.
Set uniform names for the targets to:
1. Avoid long rebuilds on the target _executable_ name changed
2. Provide the same name for different executables and/or different setup (use-cases are `cmake --build . --target game-server` and various CMake target lookups in IDEs)
Those changes are necessary but not enough to allow CI for custom app name on all platforms.
Personally this 'll allow me switch to between DDNet and Infclass branches faster and without breaking the targets configuration (e.g. with that patchset I can have `game-client` as an active target in both branches), and also reduces the conflicts in `CMakeLists.txt`.
Easier to switch between the forks => easier to contribute.

Replacing the C standard headers with the C++ standard headers causes various `error: call to 'floor' promotes float to double [performance-type-promotion-in-math-fn,-warnings-as-errors]`, which are fixed by using the C++ std math functions or our own math functions instead of the C math functions.
- Use `absolute` instead of `abs` and `fabs`.
- Use `std::floor` instead of `floor` and `floorf`.
- Use `std::ceil` instead of `ceil`, `ceilf` and `round_ceil`.
- Use `std::round` instead of `round` and `roundf`.
- Use `std::sin` instead of `sin` and `sinf`.
- Use `std::asin` instead of `asin` and `asinf`.
- Use `std::cos` instead of `cos` and `cosf`.
- Use `std::acos` instead of `acos` and `acosf`.
- Use `std::tan` instead of `tan` and `tanf`.
- Use `std::atan` instead of `atan` and `atanf`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::log` instead of `log` and `logf`.
- Use `std::log2` instead of `log2` and `log2f`.
- Use `std::log10` instead of `log10` and `log10f`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::sqrt` instead of `sqrt` and `sqrtf`.
- Use `std::fmod` instead of `fmod` and `fmodf`.
- Use `direction(Angle)` instead of `vec2(std::cos(Angle), std::sin(Angle))`.
- Use `length(vec2(x, y))` instead of `std::sqrt(x * x + y * y)`.
- Remove unused `NormalizeAngular` and `AngularDistance` functions.
Instead of returning the number of bytes written, which are platform specific, return `true` on success and `false` on failure, so no platform specific code is required when checking the result.
Use `bytes_be_to_uint` and `uint_to_bytes_be` instead.
As casting between `int` and `unsigned` preserves the bit representation of the value, it's not necessary to apply additional tricks to convert between `char` arrays and `int`.

Using `str_format` without format arguments is equivalent to `str_copy`, but using the latter is more efficient and readable.
As `str_format` also returns the result `str_utf8_fix_truncation`, i.e. the potentially truncated string length, the return value is also added to `str_copy` so existing invocations don't need to be adjusted.
6299: Show error message when downloaded map cannot be saved r=def- a=Robyt3
Check if deleting the old map file or renaming the temporary downloaded map fails. If so, show an error message which indicates that the user should delete the map file manually.
Sometimes downloaded map files seem to end up with wrong permissions, ownership or with read-only flag set, which makes the client unable to delete them.
Closes#5825.

6289: Fix `sv_vanilla_antispoof` for vanilla 0.6.5 clients r=def- a=Robyt3
This fixes issues that prevented vanilla 0.6.5 clients from joining DDNet servers with `sv_vanilla_antispoof 1` (closes#2074).
The dummy map was not valid. The size of the tiles and game layers was calculated incorrectly. The last member variable included in `CMapItemLayerTilemap` version 2 should be `m_Data`. Previously only the size of the member `m_aName` was subtracted from the total size, which was resulting in an incorrect item size, as the size of the following 5 members also needs to be subtracted.
The handshake messages were packed incorrectly. The message ID and the system flag were not added to the six packers that are passed to `SendMsgs`. The lines that are removed in this function seemed to assume that the message ID was already added but not packed, which was no longer the case. Presumable at some point `CMsgPacker` was changed without adapting the vanilla antispoof feature. Now, the message ID and system flag are properly packed when initially creating the message packers.
The `dummy_map` tool is improved to also print the generated map file's hashes and data as a C style array, so the data can immediately be copied to `network_server.cpp`.

This function removes the registry keys that are created with `shell_register_protocol` and `shell_register_extension`.
According to the Microsoft documentation, only the keys for the program IDs should be deleted.
The keys that associate the file extensions with the program IDs should be kept, as Windows will automatically ignore the value if the program ID does not exist.
See: https://learn.microsoft.com/en-us/windows/win32/shell/fa-file-types#deleting-registry-information-during-uninstallation
The `shell_update` function notifies the system when the shell needs to be updated due to a changed protocol or file association.
An output parameter is added to the `shell_register_protocol` and `shell_register_extension` functions, to determine whether the shell needs to be updated after calling the functions.
We only check whether the application path and program association were changed, instead of checking whether any key or value was changed, as this reduces the amount of necessary checks and we assume that the other values are not externally changed.
Because updating the shell is a potentially expensive operation, this should only be done when necessary and only once after registering all protocols and extensions.
This function register a file extension on Windows by creating the necessary registry keys and values.
The file extension is only registered for the current user in the registry key `HKEY_CURRENT_USER\SOFTWARE\Classes`, so admin privileges are not required.
Windows does not allow changing the default file extension handler programatically. When the user opens a file for which a new file extension handler exists, a dialog is shown that allows the user to change the default handler.

5599: Add support for Rust code in DDNet r=def- a=heinrich5991
The glue is done using the [cxx crate](https://cxx.rs/) on the Rust side.
As a proof-of-concept, only a small console command (`rust_version`) printing the currently used Rust version was added.
You can generate and open the Rust documentation using `DDNET_TEST_NO_LINK=1 cargo doc --open`.
You can run the Rust tests using `cmake --build <build dir> --target run_rust_tests`, they're automatically included in the `run_tests` target as well.
Rust tests don't work on Windows in debug mode on Windows because Rust cannot currently link with the debug version of the C stdlib on Windows: https://github.com/rust-lang/rust/issues/39016.

Converting wide-char (UTF-16) to multi-byte (UTF-8) takes 1-2 wide-chars from the input and transforms them to 1-4 bytes, so having `char` and `WCHAR` buffers with equal static lengths means that this function can fail due to insufficient buffer sizes when the user has folder or files with very long names (many unicode codepoints).
Therefore checks are added that allow only the error `ERROR_INSUFFICIENT_BUFFER` when `WideCharToMultiByte` fails, which is expected on very long paths, as these would also lead to further errors later in the code. The respective functions will now fail with a return and ignore files that have too long names.
This could only completely be fixed using dynamically sized buffers for all paths, which seems like too much work and overhead.
Other errors are not expected and hence caught by the assertions, as those would indicate programming errors like wrong arguments being passed.
Reference: https://learn.microsoft.com/en-us/windows/win32/api/stringapiset/nf-stringapiset-widechartomultibyte
The second buffer was previously used when calling `fs_is_dir` explicity, but it has become from obsolete from #4657 by using the flag `FILE_ATTRIBUTE_DIRECTORY` instead.
Extract `windows_format_system_message` and allocate appropriate buffer for the formatted system error messages, so messages of any length can be displayed.
The flag `FORMAT_MESSAGE_ALLOCATE_BUFFER` is used so `FormatMessageW` allocates the buffer which must later be freed with `LocalFree`.
The flag `FORMAT_MESSAGE_MAX_WIDTH_MASK` is also added so the formatted message will not contain any line breaks at the end, which would make log messages less readable.
Reference: https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-formatmessagew
Converting multi-byte (UTF-8) to wide-char (UTF-16) take 1-4 bytes from the input and transforms them to 1-2 wide-chars, so having `char` and `WCHAR` buffers with equal lengths should mean that this function can't fail due to insufficient buffer sizes, unless a path that's already too long for Windows is being used internally.
Other errors are also not expected, as those would indicate programming errors like wrong arguments being passed.
The maximum length for paths in the Win32 API is 260 characters. This limitation can be lifted in Windows 10, but it must be done explicitly (opt-in) both in the Windows Registry by the user and in the application's manifest by us.

Make sure the Windows debugger logger does not fail when log messages are too long.
The first call to `MultiByteToWideChar` gets the required size of the wide-char buffer, which should be at least one for the null termination. The second call is expected to produce exactly the same number of characters.
The function `MultiByteToWideChar` can't fail unless wrong arguments are passed, when the buffer size is set correctly by calling the function twice. The returned buffer size on the second call should always match the buffer size determined with the first call.

5942: Support unicode with ExcHndl, use upstream module offsets, handle errors r=def- a=Robyt3
Update Dr. Mingw (ExcHndl) to 0.9.8.
Use the new `ExcHndlSetLogFileNameW` function to set the exception log file name using wide characters, to support paths containing unicode.
It's not necessary to call `ExcHndlInit` explicitly after loading `exchndl.dll`, as the `DllMain` will already initialize the exception handler when the DLL is loaded. Module offsets are supported by upstream ExcHndl now, so we don't need to provide our own version that supplies the module offset to `ExcHndlInit` anymore. Upstream ExcHndl will also resolve the source code lines for addresses automatically, when the executable is build with debug information.
Handle the cases that the exception handling module cannot be loaded and that the `ExcHndlSetLogFileNameW` function cannot be found in the module.
Update `scripts/parse_drmingw.sh`:
- Parse both old and new module offsets.
- Use tabs instead of spaces consistently.
- Reset the ANSI color after printing colored messages.
Closes#5877.

- Parse both old and new module offsets.
- Use tabs instead of spaces consistently.
- Reset the ANSI color after printing colored messages.
- Retrieve version information of `kernel32.dll` without providing a fixed path to the Windows directory, to handle the case that Windows is not installed in the default location `C:\Windows`. This works because `GetFileVersionInfoSizeW` and `GetFileVersionInfoW` use the search sequence defined by `LoadLibrary`, so they will find the DLL without the path explicitly being specified. The version is retrieved from `kernel32.dll` instead of `user32.dll`, as the former is more commonly used for this purpose.
- Use the unicode (wide character) functions consistently instead of the ANSI functions.
- Use the correct format specifier `%hu` for `unsigned short` (i.e. `WORD` in the Windows API).

Update the `str_skip_to_whitespace(_const)` functions according to their documentation, which already stated that `\r` was also considered as whitespace.
This changes `str_comp_filenames` so it sorts filenames case insensitive while also comparing digits characters as numbers.
This makes filename sorting consistent with the behavior in Windows Explorer.
- Change argument and return value to `const char *`, as the string is not modified by this function.
- Use our own `str_isspace` instead of standard library `isspace`.
- Always trim leading whitespace to correctly handle inputs with leading whitespace.
For more consistent usage of the Windows API. `_wgetcwd` seems to be a wrapper around `GetCurrentDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wgetcwd).
Pass the correct size of the wide char buffer instead of passing the size of the output parameter buffer.
Remove a nullptr check. The argument should never be null and we don't check for null arguments anywhere else.
For more consistent usage of the Windows API. `_wchdir` seems to be a wrapper around `SetCurrentDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wchdir).
For more consistent usage of the Windows API. `_wmkdir` seems to be a wrapper around `CreateDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wmkdir).
Previously, the socket addresses were truncated as the `msg_namelen`
field is both input **and** output: After receiving an IPv4 packet, the
socket address field would be too short for an IPv6 address.
Remove square brackets to reduce the amount of space used.
Add log level indicator. The position between timestamp and system was
chosen because it is at a fixed position (unlike after the system) but
the log still remains naively sortable (which wouldn't happen if we were
to place it in front of the timestamp.

On Windows, the check was incorrectly using logical or instead of bitwise or. Checking for the flag `FILE_ATTRIBUTE_REPARSE_POINT` is not necessary, as the `FILE_ATTRIBUTE_DIRECTORY` will correctly be set when the target of a symbolic link is a directory. This otherwise causes symbolic links to files to be incorrectly handled as directories.
On Linux, the minor performance optimization of using `entry->d_type` is reverted and `fs_is_dir` is used instead. This internally uses `stat`, which correctly returns the attributes for the symbolic link targets.
