Add easter, halloween and xmas to `enum ETimeSeason` and `time_season` function. This unifies the logic for detecting these events and seasons in one function. This allows adding support for special easter, halloween and xmas theme maps in the future. The `localtime` function is not used outside `system.c` anymore. The code for detecting easter is taken from upstream.
Check whether the demo file has been closed due to a playback error when calling `DoTick` in loops, to prevent crashes on operating systems with assertions for correct C library usage. On Windows, `warning: Invalid parameter passed to C runtime function` was printed to the debug console in this case.
Ensure server password can fit username and password separated by colon, so there is no discrepancy where some passwords work in rcon but not for reserved slots.
There is no need to limit the length of server password, rcon username, rcon password and rcon commands when packing them into their respective messages. The source buffers for these strings are already limited in length and the message packer ensures that the maximum packet size is not exceeded.
Add parameter `int Conn` to `SendInfo` and `SendReady` functions and use existing `SendEnterGame` function to reduce duplicate code for sending the same messages for main and dummy connections.
Use `m_aCurrentDemoSelectionName` and `m_DemolistStorageType` for the demo render popup instead of using `m_DemolistSelectedIndex`, which can be invalid when the demo render popup is not opened from the demo browser.
Closes#7347.
The host lookup job and the engine interface are independent so they are moved to separate files.
The include of `engine.h` in `client.h` is therefore unnecessary and other includes also had to be adjusted because of this.
The variable `m_VersionServeraddr` is unused and therefore removed. The host lookup job is currently not used on the client-side.
Previously, the IME candidate window was aligned with the top-right corner of the text bounding box (when rendering the text until the caret offset). This does not work correctly for text spanning multiple lines, causing the IME candidate window to be displayed at the X position of the longest line instead. Additionally, text clipping in the chat was not considered, as `CLineInput` is not aware of the clipping implemented in `CChat`, causing the IME candidate window to be moved up too far.
This is fixed by getting the correct rendered position of the caret offset using `m_CursorRenderedPosition`. Vertical alignment is also changed so only one line of text is considered, which makes the behavior more consistent with Windows' native IME candidate window and avoids larger changes in `CLineInput` to make it aware of clipping.
Handle the return values of all uses of the `io_read`, `io_skip` and `io_tell` functions in `CDemoPlayer`, to handle truncated demo files and other unexpected file reading and seeking errors during demo playback.
Show more detailed error message popups when demos cannot be loaded due to errors and when demo playback is stopped unexpectedly due to errors. Previously, only a generic message "Error loading demo" was shown when loading failed and no error message was shown when demo playback is stopped due to errors.
Add checks to ensure that the ticks read from demo chunk headers are in the valid range (cf. `MIN_TICK` and `MAX_TICK` constants). Playing demos with invalid ticks is prevented entirely, as the invalid ticks would cause issues in other places. The server never uses ticks outside the valid range, so invalid ticks should never occur in correctly recorded demos.
Additionally, checks are added to detect if a tickmarker chunk with a tick delta occurs before a tickmarker chunk defining an initial tick. The tick delta is only meaningful when an initial tick has already been defined, so if this is not the case the demo is also considered invalid.
