2021-07-20Codechange: Make OverflowSafeInt constexprCharles Pigott
2021-07-20Codechange: Remove (unused) ability to specify min/max of OverflowSafeIntCharles Pigott
2021-07-20Codechange: Use GCC/clang builtins for overflow safety when supportedCharles Pigott
2021-07-20Fix: OverflowSafeInt could underflowCharles Pigott
Notably, a company with an extremely negative amount of money would suddenly become very rich
2021-07-20Fix: OverflowSafeInt negation not handling INT64_MINCharles Pigott
INT64_MIN negated is above INT64_MAX, and would overflow. Instead, when negating INT64_MIN make it INT64_MAX. This does mean that -(-(INT64_MIN)) != INT64_MIN.

2021-07-02Feature: framework to make savegames self-descriptivePatric Stout
We won't be able to make it fully self-descriptive (looking at you MAP-chunks), but anything else can. With this framework, we can add headers for each chunk explaining how each chunk looks like in detail. They also will all be tables, making it a lot easier to read in external tooling, and opening the way to consider a database (like SQLite) to use as savegame format. Lastly, with the headers in the savegame, you can freely add fields without needing a savegame version bump; older versions of OpenTTD will simply ignore the new field. This also means we can remove all the SLE_CONDNULL, as they are irrelevant. The next few commits will start using this framework.
2021-06-13Codechange: convert printf DEBUG statements to fmt Debug statementsrubidium42
2021-06-03Codechange: use "[[maybe_unused]]" instead of a wide variety of other ways ↵Patric Stout
we had While at it, replace OTTD_ASSERT with WITH_ASSERT, as this is always set if assert() is valid. No matter if NDEBUG is set or not.
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: pass large parameter by reference instead of value, especially ↵rubidium42
in a recursive function
2021-04-21Cleanup: Replace single-use Pair struct with std::pair.Peter Nelson
This struct is defined in geometry_type but not used by any geometry-related code, only for subsidy code where both parameters are cast from int to NewsReferenceType.
2021-04-01Fix: building on Raspberry Pi failed because of const vs constexpr (#8924)Patric Stout
2021-02-17Fix: [SDL2] simplify what to redraw to prevent tearing (#8685)Patric Stout
When there are a lot of rects to redraw, of which one of the last ones is almost the full screen, visual tearing happens over the vertical axis. This is most visible when scrolling the map. This can be prevented by using less rects. To simplify the situation, and as solutions like OpenGL need this anyway, keep a single rect that shows the biggest size that updates everything correctly. Although this means it needs a bit more time redrawing where it is strictly seen not needed, it also means less commands have to be executed in the backend. In the end, this is a trade-off, and from experiments it seems the approach of this commit gives a better result.

2020-12-15Codechange: Make use of the improved C++17 emplace_back function.Michael Lutz
2020-07-03Fix: Globally apply preprocessor directive coding styleTechGeekNZ
Global; except for the 32-bit SSE blitter, which has some #DEFINEs in not-very-nice places.
2020-06-05Add: introduce CMake for project managementPatric Stout
CMake works on all our supported platforms, like MSVC, Mingw, GCC, Clang, and many more. It allows for a single way of doing things, so no longer we need shell scripts and vbs scripts to work on all our supported platforms. Additionally, CMake allows to generate project files for like MSVC, KDevelop, etc. This heavily reduces the lines of code we need to support multiple platforms from a project perspective. Addtiionally, this heavily improves our detection of libraries, etc.
2020-05-21Codechange: Replace SmallPair with std::pair.Michael Lutz
std::pair is already the smallest possible pair, and it already handles non-POD types correctly.

2019-04-21Codechange: Use std::underlying_type for DECLARE_POSTFIX_INCREMENT.peter1138
2019-04-21Fix: Replace int with std::underlying_type in DECLARE_ENUM_AS_BIT_SET.peter1138
This fixes 64 bit uses of this macro.

2019-04-15Codechange: No need for AutoFreePtr if there's std::unique_ptr.Michael Lutz
2019-04-15Codechange: Replace SmallStackSafeStackAlloc with std::array.Michael Lutz
The only port that ever used it to make heap allocations instead of stack ones was the NDS port, which got thrown out some time ago.
2019-04-13Fix 801cbea9c: operator< is not always the best ideaglx
Also removes unused and anyway broken SmallMap::SortByKey() function.
2019-04-13Codechange: use std::sort() for all std::vector typesglx
2019-04-10Codechange: Use null pointer literal instead of the NULL macroHenry Wilson
2019-04-09Remove: AutoFreeSmallVector.Michael Lutz
The last use was for storing a list of memory blocks. As the way these lists are accessed is very specific, it is easier to just write an explicit destructor instead of trying to exactly match the behaviour.
2019-04-09Codechange: If something is a vector of strings, use a vector of strings ↵Michael Lutz
instead of an AutoFreeSmallVector.
2019-04-09Codechange: Switch DropDownList to directly use std::vector, thus making ↵Michael Lutz
AutoDeleteSmallVector obsolete. DropDownListItem are strongly managed using std::unique_ptr to ensure leak-free handling. Appropriate use of move-semantics make intent a lot clearer than parameter comments and allows the compiler to generate copy-free code for most situations.
2019-04-06Codechange: Replace custom mutex code with C++11 mutex'es.Michael Lutz
A conforming compiler with a valid <mutex>-header is expected. Most parts of the code assume that locking a mutex will never fail unexpectedly, which is generally true on all common platforms that don't just pretend to be C++11. The use of condition variables in driver code is checked.
2019-03-28Fix #7165: Const overload SmallMap::Contains(key) compared wrong types.Michael Lutz
Const and non-const Find() have different return types.
