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.
The client/server jobpools were previously only using a fixed number of 2 threads. Now the pools use `2 * hardware-concurrency + 2` threads, which should provide better performance overall, as we expect threads to often wait on I/O.
Previously all demo players checked `IVideo::Current` to render a video, which would cause issues when rendering a demo while a demo slicing background job is running. Now video rendering can be toggled for each demo player individually and is only enabled for the main demo player.
Use member instead of static variables for demo player snapshot data. The static variables would otherwise cause issues when multiple demo players are playing at the same time, especially demo players used in background jobs for replay demo slicing. This hopefully closes#7068.
Use composition instead of inheritance for demo player listener to avoid temporarily storing a pointer to a local variable in a member variable.
Fix demo player file not being closed when demo recorder file cannot be opened during demo slicing.
Add assertions to check that demo recording/playback is not started when already running.
Add assertions to check that demo recording/playback is stopped before the respective demo recorder/player is destroyed.
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`.)
