The TODO in the `Dilate` function is removed, as the code already appears to be safe without additional checks. The variable `k` is at most `(w * h - 1) * BPP`, as `ix` and `iy` are clamped to maximum `w - 1` and `h - 1` respectively. Because `p < BPP - 1` the index `k + p` is therefore always valid for the buffers. (The caller must ensure that the source and destination buffers are of size `w * h * BPP`.)
Improve layout of demo browser buttons, search and checkbox. Use icons for most buttons. Decrease size of UI elements.
Move demo details from below the file browser to a side panel on the right, which is the same size as the server browser side panel. Use ellipsis to truncate the SHA256 instead of rendering only half of it with reduced font size. Show "map not included" instead of "0.00 KiB" for the map size of demos that don't include a map.
Remove the "Markers" column, as it is not very useful to see for all demos and sort by.
Closes#7275.
Simplify the usage of datafile reader and writer by adding utility functions to read and write zero-terminated UTF-8 strings.
Improve validation of string data read from datafiles. It is ensure that string data is null-terminated, has no internal NUL-characters and is valid UTF-8.
Fix loading of external sounds in the editor. The wrong path variable was being used, so the sound files would not be loaded from correct folder.
Add tests for new datafile reader/writer functions.
When `IMap::Load` fails, other components will continue to use the old map. However, if `IMap::Load` failed after the map was already successfully read with the datafile reader then other components kept their pointers to the old, invalid datafile reader items and data, causing random crashes in collision code. This is fixed by using a separate datafile reader to read the new map and only applying the datafile reader globally when loading was entirely successfully.
An error message is added for the case that a map has an unsupported version, which is currently the only case where a map can fail to load after the datafile was read successfully.
In particular, the block maps `blmapPepe`, `blmapV5` and `blmapDT-UPTU` did not have a version map item and were fixed separately.
Closes#7218. Regression from #5737.
The pixel size (bytes per pixel) always has to be 4 for the `Dilate` function to work correctly. This is already checked before calling the function, so the redundant argument which is always `4` can be removed.
The wrong color channel count was being used for loading images that use an indexed color palette, which was causing the loading to fail with the error "bytes in row incorrect". Now the correct color channel count is retrieved using the libpng API.
Closes#7157.
Use config manager to reset `ui_page` to the default, instead of using `CMenus::PAGE_DDNET` directly (which is the default).
Check current type of serverbrowser instead of checking the current `ui_page` against `CMenus::PAGE_DDNET` and `CMenus::PAGE_KOG`.
Using `dbg_stress 1` now only does the following (in debug build):
- Randomly send inputs.
- Randomly send chat messages.
- Randomly connect/disconnect to server configured with `dbg_stress_server` (`localhost` by default).
Previously it also did the following, which is not useful for this debugging feature and only complicates the code unnecessarily:
- Cause images and sounds not to be loaded.
- Render only every tenth frame.
- Always use inactive graphics refresh rate.
Instead of keeping track of a permanently empty `CSnapshot` object in client and server separately, add `CSnapshot::EmptySnapshot` to access a singleton empty `CSnapshot`.
Mark pointer parameters of snapshot functions as `const` when possible.
Simplify the handling of free texture indices by using `-1` only for indices which are currently in use, whereas the size of the vector is now used to indicate the last free index. Otherwise the assertions incorrectly detect the last texture index always being in use because `-1` was used for both states.
Previously, if the demo header strings did not contain zero-termination, the client would render the strings and any following non-zero memory from the demo header.
Now, demos will not be loaded, if any string in the header is not zero-terminated or not valid UTF-8.
When using `auth_remove`, the key indices for the default helper, mod and admin passwords were not properly adjusted, causing the wrong passwords to be used for the username-less logins.
The key indices for connected clients were also not properly adjusted, causing the wrong identity to be shown for currently authenticated clients when using the `status` command.
Closes#6427.
Most variables used in the sound engine were static globals, as they are used in the static sound mixing function. The global variables are replaced by member variables, by passing the sound interface as user-data for the SDL mixing callback. The `Mix` function is made a public member function of `ISound` instead of being exposed using `ISoundMixFunc GetSoundMixFunc()`.
This allows to remove the direct dependency of the engine sound on the engine video, by instead passing the sound mixing function as a lambda to the engine video in the engine client.
The old WavPack reader function interface does support passing a user-data pointer to the callback function, so global variables are still used here.
Replace existing hard-coded support for two "networks" with support for a dynamic list of "communities" which are indexed by a string-ID, though right now the DDNet and KoG communities are still hard-coded. The communities now also support an arbitrary number of associated countries, types and servers. This is a refactoring to prepare for getting the list of communities dynamically from the server and removing the DDNet and KoG tabs from the serverbrowser.
New UI elements were being created for every server info after refreshing the server list. At the same time, old UI elements were not being deleted when the server info objects are deleted. The use of `mutable` for this purpose was also rather unclean.
Now, a separate `std::vector` of UI elements is kept for all server browser entries, instead of associating the UI elements directly with the server info.
Move the "Filter", "Info" and "Friends" tabs to the top, above the tab content. Use icons instead of text for the tabs. Use animator to animate the tabs on mouse-over. Closes#6613.
Make spacings, corners and font sizes used in the filter, details and friends tabs more consistent.
Remove some unnecessary dark UI rect backgrounds.
Improve alignment of the number of friends with the heart icon for entries in the server list.
Improve layout of countries and types filters. Make the filters scrollable when there are many entries.
Refactor most of the server browser in preparation for replacing the DDNet and KoG tabs with a community filter, which will work like the countries and types filters. Split rendering of different server browser sections into multiple functions to improve readability. Reduce duplicate code for the countries and types filters.
Make the skipping duration adjustable with a dropdown menu. The dropdown menu includes the durations 1s, 5s, 10s, 30s, 1m, 5m and 10m. The default duration is 5s. Skipping durations longer than the current demo are not shown. The dropdown menu is only shown if two or more durations would be shown.
Add buttons for skipping the duration, which was previously only possible with the hotkeys.
Add Ctrl+Left/Right hotkeys for skipping to chapters.
Add Shift+Left/Right hotkeys for adjusting the skipping time.
The Left/Right arrow keys and the J/L keys work identically for all hotkeys now.
Ignore ctrl, shift and alt keys for demo speed changes with the mouse wheel, to better support actions like zooming being bound to alt+mousewheel etc.
Also handle keypad enter key for play/pause like the normal return key.
Use arrow up/down icon for speed adjustment buttons, so that the "backward/forward" icons can be used for duration skipping instead.
Closes#7064.
Check if maximum number of lines has been reached before starting a new line, to prevent the text cursor from reporting the wrong number of lines and text height in that case.
Don't truncate console lines at 255 bytes anymore. Especially lines containing many Unicode characters would be adversely affected by this limitation.
Instead, truncate console lines after 10 wrapped lines are rendered. Rendering too many lines at once currently breaks the console scrolling. Rendering an ellipsis is currently not possible when rendering text with a maximum line count.
Increase buffer sizes to handle long (esp. invalid) command inputs.
Closes#7132.
If the player slots update the 0.7 clients have to be informed
about it. Otherwise the client can block the join button
if the outdated playerslots are filled already.
Use `WaitForPipeDrain` to deterministically wait for the pipe to drain instead of using `Start-Sleep`.
Use `Dispose` instead of `Close` to properly flush and close the pipe stream.
Add error handling for connection timeout and I/O errors.
Handle `ERROR_BROKEN_PIPE` separately when peeking at pipe, as this happens when the pipe is disconnected immediately after connecting it or after reading the previous message.
Don't ignore `ERROR_BAD_PIPE` anymore, as the pipe should never be in a disconnected (i.e. bad) state at this point of the function.
Use `enum EImageFormat` type for image format literals and variables.
Add `PixelSize` function to get the number of bytes/color channels per pixel for a specified image format.
Remove unused store format argument of texture loading functions. All textures are automatically being stored as RGBA, so the argument was unused. Also remove the therefore unused `FORMAT_AUTO`.
Rename variables consistently to `PixelSize` and use `size_t`, instead of mixing different names like `BPP` and `ColorChannelCount`.
Validate image format loaded from maps using `CImageInfo::ImageFormatFromInt`. Add `FORMAT_ERROR` to represent invalid formats.
Remove redundant `PixelSize` parameter from graphics backends and commands, which can be derived from the texture format.
Fix memory leak when RGB image data is being converted to RGBA format when saving map in editor.
This config variable was only settable in the server console but only read in the client, so it was effectively unusable. It also has no use case right now.
The log message is otherwise shown multiple times when starting the client.
Now it's only shown when the `record` command is used manually, i.e. not for automatically recorded demos anymore.
Render a pause/play icon in the center of the screen when pausing/unpausing while the menu is not active.
The icon fades in and out over 0.5 seconds and slightly increases in size over that time.
When starting demo rendering with initial pause, the pause indicator is rendered continuous until playback is first started, to ensure that the initial pause state is communicated clearly to the user. The initial pause indicator is not included in the rendered demo, but pausing and unpausing later during demo rendering will cause it to be included in the video, same as other UI elements. Closes#7044.
The config variable `cl_demo_show_pause` (`0/1`, default `1`) is added to hide the pause indicator entirely, for example to render a demo with multiple pauses without the indicator.
The pause indicator and also the existing speed indicator are not rendered (anymore) while the menu is active, as the menu already contains this information.
Add more efficient function for formatting integer values as strings.
A benchmark shows that using this function is significantly faster than using `str_format`. It is faster by a factor of 220 with Clang 15.0 O2 (https://quick-bench.com/q/BlNoLnlyqxipf4jvsFTUxKMHDJU) and by a factor of 11 with GCC 12.2 O2 (https://quick-bench.com/q/Fxf9lDCTqXBF4pIa_IyZ5R0IqYg).
This increases FPS in the editor by ~25% when many numbers are rendered for switch/tele/speedup/tune layers or with "Show Info" being enabled.
The additional static analysis for `std::to_chars` revealed that the wrong size was used in `CHud` for `aScoreTeam[TEAM_RED]` and `aScoreTeam[TEAM_BLUE]`.
This requires incrementing the macOS deployment target from 10.13 to 10.15.
When connecting to the SQLite database fails, e.g. because the `.sqlite` file is corrupted, the server would crash with the assertion "Tried connecting while the connection is in use" when a player joins and performs any action.
This is fixed by resetting the use-flag when connecting to the SQLite database fails, which is the same behavior as for the MySQL database connection.
vanilla 0.6 joins weren't recorded. Also after map change, for the
existing players these Join chunks were missing. Just add these
message for existing players now and add OnClientEngineJoin in all
code paths with clients connecting.
Add `str_utf8_offset_bytes_to_chars` and `str_utf8_offset_chars_to_bytes` functions to base system to convert between byte and UTF-8 character offsets in UTF-8 strings.
Previously, this was separately implemented in the textrender and in the lineinput helper.
These textrender functions are entirely replaced by the new functions:
- `ITextRender::SelectionToUTF8OffSets` (by `str_utf8_offset_chars_to_bytes`)
- `ITextRender::UTF8OffToDecodedOff` (by `str_utf8_offset_bytes_to_chars`)
- `ITextRender::DecodedOffToUTF8Off` (by `str_utf8_offset_chars_to_bytes`)
These lineinput helper functions are reimplemented using the new functions:
- `CLineInput::OffsetFromActualToDisplay` (uses `str_utf8_offset_bytes_to_chars`)
- `CLineInput::OffsetFromDisplayToActual` (uses `str_utf8_offset_chars_to_bytes`)
Register the `OnWindowResize` listener in the engine client instead of the game client and properly dispatch the event also to the editor, so text containers in the editor are cleared when the window is resized.
Closes#7018.
Fix text containers rendering broken text after the language is changed, as this cleared the glyph atlas without clearing the references to the glyph positions in the text containers. Now `OnWindowResize` is also called on language change to reset all text containers.
However, the glyph atlas is not cleared on normal window resize anymore, because this seems to be unnecessary.
Replace skyline-based texture atlas algorithm with a rectangle packing algorithm that tracks empty atlas sections using `std::vector`s. The algorithm is very loosely inspired by https://github.com/TeamHypersomnia/rectpack2D.
Increases texture atlas utilization from ~70% to ~90-94%, i.e. less space in the atlas is unused.
Decreases the computational time to find suitable free regions in the atlas by factor 40x-164x (depending on atlas dimension and utilization). In absolute numbers, the computational time necessary for a glyph being added to the atlas is decreased from 0.0556ms-0.4679ms to 0.0013ms-0.0051ms (depending on atlas dimension and utilization).
The memory usage for the texture atlas algorithm increases from a maximum of ~128 KB to a maximum of ~3 MB.

Add `fonts/index.json` which specifies:
- List of all font files that should be loaded (filenames).
- Default font (specified by family name or by family and style name).
- Font variants for different languages, using the name of the language file as key.
- Fallback fonts.
- Icon font.
There are characters (e.g. all in `刃直海角骨入`) that look different depending on the language of the content being Japanese, Simplified Chinese, Traditional Chinese and Hangul, because Unicode uses the same codepoint for characters regardless of the language. To render these characters correctly, the active variant font is switched depending on the selected language.
The `ITextRender` interface is changed so the current language variant can be set using `SetFontLanguageVariant` and the default and icon fonts can be toggled using `SetFontPreset`. The class `CFont` is removed entirely.
The text render is restructured: The font faces and font atlas are now managed by a separate class `CGlyphMap` like on upstream. As the text fill and outline textures always have the same size, the texture skyline only needs to be stored once and free positions in the atlas only need to be calculated once for each glyph instead of separately for the fill and outline textures.
The font files and their licenses are also updated:
- Update Source Han Sans to version 2.001.
- Update Glow Sans Japanese Compressed to version 0.93.
- Update Deja Vu Sans to version 2.37.
- Update Font Awesome icons font to March 2023 version.
Closes#6881.
`shared_ptr`s of `CServer::m_pDnsblLookup[ClientID]` are set, but not
cleaned up when done. Therefore the Job is kept alive until the player
disconnects and a new player joins on that slot. Currently this means
that the full linked list of jobs is kept alive.
When the Job is overwritten with a new job, all the remaining objects in
the list can be dropped. With enough jobs, that is causing a stack
overflow in the destructor.
This patch fixes this overflow by making the lifetime independent of the
previous Job. Jobs can get dropped after processing them, even when the
previous job is still alive.
Fixes#6954
The old code looked pretty weird. It checked for `CFGFLAG_SERVER |
CFGFLAG_GAME` being set above, and then used the passed-in parameter to
find the command. I think it'd be better to just look for `CFGFLAG_GAME`
and then find the command using `CFGFLAG_GAME`.
Check if datafile data cannot be read entirely (according to the data size specified in the header) and check for decompression errors. In case of errors, let `GetData` return `nullptr` and `GetDataSize` return `0` for the respective index.
Internally the decompressed size is set to `-1` for data which failed to load, so loading of those data will not be attempted again because it would only fail again and can cause additional log messages.
Rectangles with inverted round corners (`IGraphics::CORNER_I*`) are currently not used anywhere and also only supported when using `Draw4`.
They also feel clunky to use due to the inverted corners being drawn outside of the specified rectangle area.
Use icons for all server settings buttons. Rearrange and group buttons.
Show buttons in disabled state when they are not useable instead of hiding them.
Remove checker background from server settings list.
Overhaul hotkeys, also show hotkeys in the tooltips:
- Enter: add command
- Alt+Enter: update command (previously M)
- Alt+Up/Down: move command up/down (previously no hotkey)
- Delete: delete command
Don't activate command lineinput when selecting, moving or deleting elements, as this prevents the listbox from accepting the delete hotkey.
Fix server settings listbox being active while file dialog is open.
Ensure extra editor dragbar area matches the respective toolbar size.
Remove spacing on the left side of extra editors to improve alignment.
Increase status bar button sizes and make them consistent.
Use `enum` to track active extra editor instead of using multiple `bool`s.
Disable extra editor buttons when tile picker is shown, as the extra editors are not rendered in this case.
Port the `CJsonWriter` utility class from upstream, which makes outputting correct JSON easier.
Add `CJsonWriter` as an abstract class that can write to different outputs. Two implementations `CJsonFileWriter` (writes to a file) and `CJsonStringWriter` (writes to an `std::string`) are added. Upstream `CJsonWriter` can only write to files.
The same tests are added for both implementations. Duplicate code is avoided by using typed tests with two separate test fixtures.
`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.
When memory for a command or data in the command buffer cannot be allocated in `CGraphics_Threaded::AddCmd` and `CGraphics_Threaded::AllocCommandBufferData` the command buffer is cleared so it should always be possible to allocated memory successfully on the second try. Therefore assertions are added and the return values and inconsistent checks of the functions are removed.
The usage of `AddCmd` is simplified by automatically deriving an error message based on the type of the template parameter.
Only add assertion to prevent empty filename, as this causes Valgrind to crash.
Handle empty filename used for special null-image separately in gameclient.
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.
Previously it reported the internal file data size (compressed). This
made the `map_resave` tool do the wrong job.

To reduce duplicate code and to add validation for tile skip everywhere.
Add separate `CMapItemLayerTilemap::TILE_SKIP_MIN_VERSION` constant and change `CMapItemVersion::CURRENT_VERSION` back to the previous version, as maps with tile skip can be loaded but skip is not used when saving.
When starting with `dbg_stress 1` the invalid texture was never actually getting loaded, which was causing the client to crash when using the Vulkan backend and starting with `dbg_stress 1`.
Additionally ensure that the invalid texture is 16x16 pixels large and loaded with the texture flags to support usage for tile rendering.
Closes#6504.
Show a short message below the existing chat mentions message that is shown in the top left area of the editor above the layers/images/sounds button when the player character is moved ingame while the editor is open. The messages are cleared when the editor is activated and when the client is disconnected.
Closes#1993.
When multiple files or folder have the same name in multiple storage locations, only pass the first entry (file or folder, whichever comes first) to the callback. To prevent files with the same name form being listed multiple times, e.g. in the demo browser, editor file browser, and asset lists.

Compressing the data with zlib takes the majority of the time when saving a datafile. Therefore, compressing is now delayed until the `CDataFileWriter::Finish` function is called. This function is then off-loaded to another thread to make saving maps in the editor not block the rendering.
A message "Saving…" is shown in the bottom right of the editor view while a job to save a map is running in the background.
While a map is being finished in a background thread another save for the same filename cannot be initiated to prevent multiples accesses to the same file.
Closes#6762.
