            const object as a data member vs normal variable
            Asked 2022-Mar-15 at 12:57

            I was trying to make a Container class that will be using an object of a class Comparator which will be passed through the template.

            So I am doing something like:

            ...

            ANSWER

            Answered 2022-Mar-14 at 16:45

            If no initializer is given for the const Comparator variable it must be const-default-constructible. But your class Comparator is const-default-constructible because it has no non-static data members. For actual rules determining that see [dlc.init.general]/7.

            This is not only the requirement for such a variable, but also the requirement to not cause the implicit default constructor to be deleted if a class has an analogues non-static member without initializer, see [class.default.ctor]/2.4.

            So your original code should compile. MSVC does compile it, but GCC and Clang do not.

            The relevant requirement for the class members was however changed to the referenced wording with a defect report: CWG 2394. Before that it required the member to have a user-provided default constructor, which is a stronger requirement than being const-default-constructible and which is exactly what you did add to make it work.

            According to both the Clang implementation status page and the GCC implementation status page the status of their implementation of the DR is unknown.

            What's the difference between $?CLASS and ::?CLASS
            Asked 2022-Feb-23 at 20:43

            The Raku docs describe ::?CLASS as a compile-time variable that answers "Which class am I in?". Then, a couple of paragraphs later, it mentions $?CLASS, and says that it answers "Which class am I in? (as variable)".

            What's the difference between these two variables? They often seem to contain the same value – do they always? Or are there differences I haven't observed?

            These two forms of compile-time variables are different syntactically.

            The syntactic form ::?foo may be used as, and will be evaluated as:

            • A term (just like a variable such as $?foo).

            • A type constraint (unlike a variable such as $?foo).

            This is because the newest version of Visual Studio Code (1.62.2) introduced this bug.

            I'm on Linux, so this may not apply or work for you, but it should if all Visual Studio Code versions are the same across all OSes.

            The Visual Studio Code team has confirmed that it will be fixed on 1.62.3

            I am using VSCode to develop something using the Flutter Framework. The Flutter extension writes logs to the debug console. I scroll the debug console to the bottom, so it stays auto-scrolling / tailing the log.

            Whenever the flutter logs write a large amount of data at once, the debug console stops tailing the log all of a sudden.

            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:

            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.

            Preferring shift over reduce in parser for language without statement terminators
            Asked 2022-Jan-04 at 06:17

            I'm parsing a language that doesn't have statement terminators like ;. Expressions are defined as the longest sequence of tokens, so 5-5 has to be parsed as a subtraction, not as two statements (literal 5 followed by a unary negated -5).

            I'm using LALRPOP as the parser generator (despite the name, it is LR(1) instead of LALR, afaik). LALRPOP doesn't have precedence attributes and doesn't prefer shift over reduce by default like yacc would do. I think I understand how regular operator precedence is encoded in an LR grammar by building a "chain" of rules, but I don't know how to apply that to this issue.

            The issue you're going to have to confront is how to deal with function calls. I can't really give you any concrete advice based on your question, because the grammar you provide lacks any indication of the intended syntax of functions calls, but the hint that print(5) is a valid statement makes it clear that there are two distinct situations, which need to be handled separately.

            Kubernetes Operators: Informers vs. reconcile loop
            Asked 2022-Jan-03 at 15:36

            I recently got started with building a Kubernetes operator. I'm using the Fabric8 Java Kubernetes Client but I think my question is more general and also applies to other programming languages and libraries.

            When reading through blog posts, documentation or textbooks explaining the operator pattern, I found there seem to be two options to design an operator:

            1. Using an infinite reconcile loop, in which all corresponding Kubernetes objects are retrieved from the API and then some action is performed.
            2. Using informers, which are called whenever an observed Kubernetes resource changes.

            However, I don't find any source discussion which option should be used in which case. Are there any best practices?

            ...

            ANSWER

            Answered 2022-Jan-03 at 15:36

            You should use both.

            When using informers, it's possible that the handler gets the events out of order or even not at all. The former means the handler needs to define and reconcile state - this approach is referred to as level-based, as opposed to edge-based. The latter means reconciliation needs to be triggered on a regular interval to account for that possibility.

            The way controller-runtime does things, reconciliation is triggered by cluster events (using informers behind the scenes) related to the resources watched by the controller and on a timer. Also, by design, the event is not passed to the reconciler so that it is forced to define and act on a state.

            Do parallel streams treat upstream iterators in a thread safe way?
            Asked 2021-Dec-13 at 17:33

            Today I was using a stream that was performing a parallel() operation after a map, however; the underlying source is an iterator which is not thread safe which is similar to the BufferedReader.lines implementation.

            I originally thought that trySplit would be called on the created thread, however; I observed that the accesses to the iterator have come from multiple threads.

            By example, the following silly iterator implementation is just setup with enough elements to cause splitting and also keeps track of the unique threads that accessed the hasNext method.

            ...

            ANSWER

            Answered 2021-Dec-13 at 17:33

            Thread safety does not necessarily imply being accessed by only one thread. The important aspect is that there is no concurrent access, i.e. no access by more than one thread at the same time. If the access by different threads is temporally ordered and this ordering also ensures the necessary memory visibility, which is the responsibility of the caller, it still is a thread safe usage.

            The Spliterator documentation says:

            Despite their obvious utility in parallel algorithms, spliterators are not expected to be thread-safe; instead, implementations of parallel algorithms using spliterators should ensure that the spliterator is only used by one thread at a time. This is generally easy to attain via serial thread-confinement, which often is a natural consequence of typical parallel algorithms that work by recursive decomposition.

            The spliterator doesn’t need to be confined to the same thread throughout its lifetime, but there should be a clear handover at the caller’s side ensuring that the old thread stops using it before the new thread starts using it.

            But the important takeaway is, the spliterator doesn’t need to be thread safe, hence, the iterator wrapped by a spliterator also doesn’t need to be thread safe.

            Note that a typical behavior is splitting and handing over before starting traversal, but since an ordinary Iterator doesn’t support splitting, the wrapping spliterator has to iterate and buffer elements to implement splitting. Therefore, the Iterator experiences traversal by different threads (but one at a time) when the traversal has not been started from the Stream implementation’s perspective.

            That said, the lines() implementation of BufferedReader is a bad example which you should not follow. Since it’s centered around a single readLine() call, it would be natural to implement Spliterator directly instead of implementing a more complicated Iterator and have it wrapped via spliteratorUnknownSize(…).

            Since your example is likewise centered around a single poll() call, it’s also straight-forward to implement Spliterator directly:
