2021-06-15Change: rework several CH_RIFF chunks to use CH_ARRAY insteadPatric Stout
This adds two byte extra to those chunks, and might feel a bit silly at first. But in later changes we will prefix CH_ARRAY with a table header, and then this change shines. Without this, we could still add headers to these chunks, but any external reader wouldn't know if the CH_RIFF has them or not. This way is much more practical, as they are now more like any other chunk.
2021-06-15Change: store length of SL_STRUCTLIST in the savegamePatric Stout
This wasn't consistently done, and often variables were used that were read by an earlier blob. By moving it next to the struct itself, the code becomes a bit more self-contained and easier to read. Additionally, this allows for external tooling to know how many structs to expect, instead of having to know where to find the length-field or a hard-coded value that can change at any moment.

2021-06-10Codechange: rename SL_LST to SL_REFLIST to highlight the "reference" partPatric Stout
You can easily mistake SlList / SL_LST to be a list of SL_VAR, but it is a list of SL_REF. With this rename, it hopefully saves a few people from "wtf?" moments.

2021-05-31Codechange: C++-ify lists for SaveLoad (#9323)Patric Stout
Basically, this changes "SaveLoad *" to either: 1) "SaveLoadTable" if a list of SaveLoads was meant 2) "SaveLoad &" if a single entry was meant As added bonus, this removes SL_END / SLE_END / SLEG_END. This also adds core/span.hpp, a "std::span"-lite.

2021-05-27Codechange: use initializer_lists for the settings tablesrubidium42
Not using vectors as those require copying from the initializer list and that makes unique_ptrs to the actual SettingDesc objects later impossible.

2021-02-13Codechange: Don't use cpp_offsetof in the save/load code.Michael Lutz
Many of the member variables that are used in save/load are inside types that are not standard layout types. Using pointer arithmetics to determine addresses of members inside types that are not standard layout is generally undefined behaviour. If we'd use C++17, it is conditionally supported, which means each compiler may or may not support it. And even then using it for individual array elements is syntactically not supported the the standard offsetof function. Unfortunately, the trickery employed for saving linkgraph settings causes quite some clutter in the settings ini files.
2020-12-22Change: [Linkgraph] Pause the game when linkgraph jobs lag (#6470)Jonathan G Rennison
Check if the job is still running two date fract ticks before it is due to join, and if so pause the game until its done. When loading a game, check if the game would block immediately due to a job which is scheduled to be joined within two date fract ticks, and if so pause the game until its done. This avoids the main thread being blocked on a thread join, which appears to the user as if the game is unresponsive, as the UI does not repaint and cannot be interacted with. Show if pause is due to link graph job in status bar, update network messages. This does not apply for network clients.
