            Possible ODR-violations when using a constexpr variable in the definition of an inline function (in C++14)
            Asked 2022-Jan-12 at 10:38

            (Note! This question particularly covers the state of C++14, before the introduction of inline variables in C++17)

            TLDR; Question
            • What constitutes odr-use of a constexpr variable used in the definition of an inline function, such that multiple definitions of the function violates [basic.def.odr]/6?

            (... likely [basic.def.odr]/3; but could this silently introduce UB in a program as soon as, say, the address of such a constexpr variable is taken in the context of the inline function's definition?)

            TLDR example: does a program where doMath() defined as follows:

            ...

            ANSWER

            Answered 2021-Sep-08 at 16:34

            In the OP's example with std::max, an ODR violation does indeed occur, and the program is ill-formed NDR. To avoid this issue, you might consider one of the following fixes:

            • give the doMath function internal linkage, or
            • move the declaration of kTwo inside doMath

            A variable that is used by an expression is considered to be odr-used unless there is a certain kind of simple proof that the reference to the variable can be replaced by the compile-time constant value of the variable without changing the result of the expression. If such a simple proof exists, then the standard requires the compiler perform such a replacement; consequently the variable is not odr-used (in particular, it does not require a definition, and the issue described by the OP would be avoided because none of the translation units in which doMath is defined would actually reference a definition of kTwo). If the expression is too complicated, however, then all bets are off. The compiler might still replace the variable with its value, in which case the program may work as you expect; or the program may exhibit bugs or crash. That's the reality with IFNDR programs.

            The case where the variable is immediately passed by reference to a function, with the reference binding directly, is one common case where the variable is used in a way that is too complicated and the compiler is not required to determine whether or not it may be replaced by its compile-time constant value. This is because doing so would necessarily require inspecting the definition of the function (such as std::max in this example).

            You can "help" the compiler by writing int(kTwo) and using that as the argument to std::max as opposed to kTwo itself; this prevents an odr-use since the lvalue-to-rvalue conversion is now immediately applied prior to calling the function. I don't think this is a great solution (I recommend one of the two solutions that I previously mentioned) but it has its uses (GoogleTest uses this in order to avoid introducing odr-uses in statements like EXPECT_EQ(2, kTwo)).

            If you want to know more about how to understand the precise definition of odr-use, involving "potential results of an expression e...", that would be best addressed with a separate question.

            Getting keyboard navigation to work with MUI Autocomplete and SimpleBar for react
            Asked 2021-Dec-30 at 20:06

            I am trying to add Simplebar scrollbar to the MUI Material Autocomplete component, instead of the default browser one. All works but doing that I've lost the ability to navigate the options list with the keyboard.

            There is this snippet from the MUI docs

            ListboxComponent If you provide a custom ListboxComponent prop, you need to make sure that the intended scroll container has the role attribute set to listbox. This ensures the correct behavior of the scroll, for example when using the keyboard to navigate.

            The problem is actually very complicated. Looking at its implementation, doesn't pass either the React ref or the role prop to the correct element. The correct element I believe is .scrollbar-content, which is very deeply nested and basically untouchable.

            ETA: In case you thought of getting cheesy with document.querySelectorAll setAttribute shenanigans, that will not work. The ref also needs to point at the correct element, and I don't think that's codeable on the workspace side.

            The cleanest solution I can think of is to use Yarn 3 (👍) and patch simplebar-react yourself, passing the needed props to .scrollbar-content. Then you do:

            Implicit implementations tend to be more common and more convenient for usage. They are less verbose and any usage of the concrete type will have the implementations of the members exposed. Implicit implementations don't include the name of the interface being implemented before the member name, so the compiler infers this. The members will be exposed as public and will be accessible when the object is cast as the concrete type.

            Can I overwrite a const object via placement-new?
            Asked 2021-Sep-23 at 17:13

            Basic.life/8 tells us that we can use the storage occupied by an object to create a new one after its lifetime has ended and use its original name to refer to it unless:

            • the type of the original object is not const-qualified, and, if a class type, does not contain any non-static data member whose type is const-qualified or a reference type, and [...]

            emphasis mine

            But, just below that we can see a note saying that:

            • If these conditions are not met, a pointer to the new object can be obtained from a pointer that represents the address of its storage by calling std​::​launder

            This explains the purposes of std::launder. We can have a class type that has const members and use placement-new to create a new object there with different internal values.

            What surprises me is the first part of the first quote. It clearly indicates that if the storage is const (not necessarily contains const members, but the whole object is declared as const), we cannot use it to refer to a new object as is, but it may imply that std::launder may fix it.

            But how would we create such object? The simplest example fails:

            How to enumerate combinations filtering repeats
            Asked 2021-Sep-14 at 22:28

            I have a list of possible choices: [[1], [2, 4], [4], [5, 6, 2], [5, 3]].

            I want to list all combinations, taking maximum one element from each sublist, without repeating elements.

            So [1, 2, 4, 5, 3] is a valid option. But [1, 4, 4, 5, 3] is not. I allow not making a choice in any sublist, so [1,4, None,5,3] is valid, as in [1, None, None, None, None], and [None, None, None, None, None].

            I can't simply enumerate all combinations then filter out the ones I don't want, since for a large list of possible choices, it would quickly become computationally infeasible (I'm looking at 25^25 maximum combinations in my project).

            edit: I would also apply some additional criteria to the results, such as filtering to have no more than a threshold of None choices, or sorting the resultant list of combinations in order of combinations with fewest None choices.

            edit: with details of the real-life case: I'd like to apply it to a list of 25 sublists, each of which can have 1-25 elements. Realisitically, each sublist will have max 15 elements, with 2-4 on average.

            So the easy solution of list(itertools.product(*choices)) then filtering is out.

            I may also wish to add other filter conditions to the list of combinations, so ideally I can filter these upfront.

            I've tried building a tree recursively, where e.g. root node has the full list of choices, child node makes the first choice [1], and has an updated list of choices where '1' is removed from all list[1:] choices.

            Struggling to implement the recursion though.

            Can you help me with any other approaches?

            Don't turn the result into a list. product is a generator. Use that to your advantage. filter is a generator too. You only hold one combination in memory this way. Sometimes a single output of product will be discarded internally without you seeing it, but it won't take up any extra space.
