Using `CMenus::PopupWarning` will immediately set the popup and override the current warning, which can hide warnings when multiple are shown at the same time. Now all warnings are added to the queue with `IClient::AddWarning`.
Add assertions to prevent map items and data that are too large to be represented by the map format from being written to maps. Additionally, ensure that the size of the whole map file is not too large to be represented by the map header.
Prevent `malloc` of size 0, which is implementation defined and should be avoided, when adding items without data, which happens for example when adding an empty array of envelope points.
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.
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.
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.
Make the title of warnings adjustable, with the default title being "Warning" to preserve existing code.
Make auto-hiding configurable, so the automatic closing of warning popups after 10 seconds can be toggled.
We only show the string value directly in the UI instead of using the demotype enum literals. There also should not be any reason to change any logic depending on whether the current demo is a server- or client-demo.
The SHA256 was effectively not optional anymore when recording demos, as it and the SHA256 extension UUID were always written to the demo file without checking for `nullptr`. Therefore the SHA256 is now passed by const reference instead of by pointer and redundant checks for `nullptr` are removed.
We already use `CClient::LoadMapSearch` to load maps for demo playback, so maps in the `maps` folder are already considered. Using the map CRC is deprecated, we do not want to check it.
Using an `std::vector` is simpler and more readable than first allocating a linked list on a heap and later copying the list to an array.
The variable `m_SeekablePoints` is removed from `CPlaybackInfo`, as it does not need to be exposed outside of `CDemoPlayer` and can be replaced with the size of the vector.
