            There's an unstable feature that will introduce let-else statements.

            Introduce a new let PATTERN: TYPE = EXPRESSION else DIVERGING_BLOCK; construct (informally called a let-else statement), the counterpart of if-let expressions.

            If the pattern match from the assigned expression succeeds, its bindings are introduced into the surrounding scope. If it does not succeed, it must diverge (return !, e.g. return or break).

            With this feature you'll be able to write:



            how to repeat the height for grid-auto-rows
            Asked 2022-Feb-08 at 22:51

            I am trying to show only the first two rows of a CSS GRID.
            The width of the container is unknown therefore it should be responsive.
            Also the content of each box is unknown.

            My current hacky solution is to define the following two rules:

            • use an automatic height for the first two rows
            • set the height of the next 277 rows to 0 height

            grid-auto-rows: auto auto 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;

            I tried repeat() like this: grid-auto-rows: auto auto repeat(277, 0px) but unfortunately it didn't set the height to 0.

            Is there any clean way to repeat height 0?

            Define a template for the two rows and then use grid-auto-rows with 0



            C++ Copy Constructors: must I spell out all member variables in the initializer list?
            Asked 2022-Jan-30 at 04:18

            I have some pretty complicated objects. They contain member variables of other objects. I understand the beauty of copy constructors cascading such that the default copy constructor can often work. But, the situation that may most often break the default copy constructor (the object contains some member variables which are pointers to its other member variables) still applies to a lot of what I've built. Here's an example of one of my objects, its constructor, and the copy constructor I've written:



            Answered 2022-Jan-30 at 02:54

            C++ Copy Constructors: must I spell out all member variables in the initializer list?

            Yes, if you write a user defined copy constructor, then you must write an initialiser for every sub object - unless you wish to default initialise them, in which case you don't need any initialiser - or if you can use a default member initialiser.

            the object contains some member variables which are pointers to its other member variables)

            This is a design that should be avoided when possible. Not only does this force you to define custom copy and move assignment operators and constructors, but it is often unnecessarily inefficient.

            But, in case that is necessary for some reason - or custom special member functions are needed for any other reason - you can achieve clean code by combining the normally copying parts into a separate dummy class. That way the the user defined constructor has only one sub object to initialise.

            Like this:



            How std::atomic wait operation works?
            Asked 2022-Jan-24 at 07:38

            Starting C++20, std::atomic has wait() and notify_one()/notify_all() operations. But I didn't get exactly how they are supposed to work. cppreference says:

            Performs atomic waiting operations. Behaves as if it repeatedly performs the following steps:

            • Compare the value representation of this->load(order) with that of old.
              • If those are equal, then blocks until *this is notified by notify_one() or notify_all(), or the thread is unblocked spuriously.
              • Otherwise, returns.

            These functions are guaranteed to return only if value has changed, even if underlying implementation unblocks spuriously.

            I don't exactly get how these 2 parts are related to each other. Does it mean that if the value if not changed, then the function does not return even if I use notify_one()/notify_all() method? meaning that the operation is somehow equal to following pseudocode?



            Answered 2022-Jan-24 at 07:38

            Yes, that is exactly it. notify_one/all simply provide the waiting thread a chance to check the value for change. If it remains the same, e.g. because a different thread has set the value back to its original value, the thread will remain blocking.

            Note: A valid implementation for this code is to use a global array of mutexes and condition_variables. atomic variables are then mapped to these objects by their pointer via a hash function. That's why you get spurious wakeups. Some atomics share the same condition_variable.

            Something like this:



            What aria label should I use for 'inactive' items in a list that the user can still interact with?
            Asked 2022-Jan-16 at 20:17

            I have a list of data in a visualisation and I want to make it as accessible as possible. There are two lists next to each other.

            The list items has two states. Multiple rows can be active or inactive. A single row could be selected.

            Selecting something in one list, will show 'related' items as active, and inactive. See the simplified example below. The user has selected "A 2", which is linked to "B 1" and "B 4", so A2 is aria-selected but there's no aria-active or aria-inactive, I thought to use aria-disabled as demonstrated - BUT does this not indicate that it is not interactable? The user can still click on the disabled item to then select it.

            Would it be better to do multiple aria-selected, and a single aria-current=true on the single 'selected' item? Would it be odd that if the user hasn't yet made a selection and everything is 'active', every item will be aria-selected=true?



            Answered 2022-Jan-14 at 23:31

            From a semantics and accessibility point of view, I'd consider separating out the controls from the visualization itself—at least in terms of the markup. This will let you use more semantic input elements, like , which come with their own states that assistive tech understands. And it will keep selection state (which is an input element trait) separate from highlighted state (which is a visualization display trait).

            You can then tie those input elements to the visualization using the aria-controls attribute.

            To denote the state of the items in the visualization itself, instead of using ARIA roles, I would suggest just using text.

            A basic example could work something like this:



            Substitution failure in an atomic constraint of template function requires-clause
            Asked 2022-Jan-07 at 15:39

            Constraints in C++20 are normalized before checked for satisfaction by dividing them on atomic constraints. For example, the constraint E = E1 || E2 has two atomic constrains E1 and E2

            And substitution failure in an atomic constraint shall be considered as false value of the atomic constraint.

            If we consider a sample program, there concept Complete = sizeof(T)>0 checks for the class T being defined:



            Answered 2022-Jan-07 at 15:39

            This is Clang bug #49513; the situation and analysis is similar to this answer.

            sizeof(T)>0 is an atomic constraint, so [temp.constr.atomic]/3 applies:

            To determine if an atomic constraint is satisfied, the parameter mapping and template arguments are first substituted into its expression. If substitution results in an invalid type or expression, the constraint is not satisfied. [...]

            sizeof(void)>0 is an invalid expression, so that constraint is not satisfied, and constraint evaluation proceeds to sizeof(U)>0.

            As in the linked question, an alternative workaround is to use "requires requires requires"; demo:

            A "multiarch" Python interpreter built on MacOS is intended to target MacOS-on-Intel and MacOS-on-Apple's-arm64.

            There is absolutely no binary compatibility with Linux-on-Apple's-arm64, or with Linux-on-aarch64. You can't run MacOS executables on Linux, no matter if the architecture matches or not.



            Are seq-cst fences exactly the same as acq-rel fences in absence of seq-cst loads?
            Asked 2022-Jan-06 at 18:26

            I'm trying to understand the purpose of std::atomic_thread_fence(std::memory_order_seq_cst); fences, and how they're different from acq_rel fences.

            So far my understanding is that the only difference is that seq-cst fences affect the global order of seq-cst operations ([atomics.order]/4). And said order can only be observed if you actually perform seq-cst loads.

            So I'm thinking that if I have no seq-cst loads, then I can replace all my seq-cst fences with acq-rel fences without changing the behavior. Is that correct?

            And if that's correct, why am I seeing code like this "implementation Dekker's algorithm with Fences", that uses seq-cst fences, while keeping all atomic reads/writes relaxed? Here's the code from that blog post:



            Answered 2022-Jan-06 at 05:14

            As I understand it, they're not the same, and a counterexample is below. I believe the error in your logic is here:

            And said order can only be observed if you actually perform seq-cst loads.

            I don't think that's true. In atomics.order p4 which defines the axioms of the sequential consistency total order S, items 2-4 all may involve operations which are not seq_cst. You can observe the coherence ordering between such operations, and this can let you infer how the seq_cst operations have been ordered.

            As an example, consider the following version of the StoreLoad litmus test, akin to Peterson's algorithm:



            Are memory orders for each atomic correct in this lock-free SPSC ring buffer queue?

            Answered 2021-Dec-31 at 12:49

            Previous answers may help as background:
            c++, std::atomic, what is std::memory_order and how to use them?

            Firstly the system you describe is known as a Single Producer - Single Consumer queue. You can always look at the boost version of this container to compare. I often will examine boost code, even when I work in situations where boost is not allowed. This is because examining and understanding a stable solution will give you insights into problems you may encounter (why did they do it that way? Oh, I see it - etc). Given your design, and having written many similar containers I will say that your design has to be careful about distinguishing empty from full. If you use a classic {begin,end} pair, you hit the problem that due to wrapping

            {begin, begin+size} == {begin, begin} == empty

            Okay, so back synchronisation issue.

            Given that the order only effects reording, the use of release in Publish seems a textbook use of the flag. Nothing will read the value until the size of the container is incremented, so you don't care if the orders of writes of the value itself happen in a random order, you only care that the value must be fully written before the count is increased. So I would concur, you are correctly using the flag in the Publish function.
            I did question whether the "release" was required in the Consume, but if you are moving out of the queue, and those moves are side-effecting, it may be required. I would say that if you are after raw speed, then it may be worth making a second version, that is specialised for trivial objects, that uses relaxed order for incrementing the head.

            You might also consider inplace new/delete as you push/pop. Whilst most moves will leave an object in an empty state, the standard only requires that it is left in a valid state after a move. explicitly deleting the object after the move may save you from obscure bugs later.

            You could argue that the two atomic loads in consume could be memory_order_consume. This relaxes the constraints to say "I don't care what order they are loaded, as long as they are both loaded by the time they are used". Although I doubt in practice it produces any gain. I am also nervous about this suggestion because when I look at the boost version it is remarkably close to what you have.
