            Creating nested objects from a flat array of strings based on a number of specific characters
            Asked 2022-Apr-03 at 11:57

            Answered 2022-Apr-03 at 07:34

            With a reduce based approach one can keep tracing/managing the correct (nested) chapters arrays where one needs to push a new chapter item into.

            Thus the accumulator can be an object which in addition to the result array features an index/map for the to be traced nested level chapters arrays.

            The to be reduced heading string gets decomposed into its '#' (hash) based flag and its text content part. This is done with the help of following regex ... /^(?#+)\s*(?.*?)\s*$/ ... which features named capturing groups. The amount of hashes (flag.length) indicates the current nested level.

            Will destructor delete built-in types and pointer objects?
            Asked 2022-Feb-18 at 14:11

            I'm a c++ beginner and now reading the C++ Primer. I have some problem about the destrucor:

            1. in chapter 13.1.3: "In a destructor, there is nothing akin to the constructor initializer list to control how members are destroyed; the destruction part is implicit. What happens when a member is destroyed depends on the type of the member. Members of class type are destroyed by running the member’s own destructor. The built-in types do not have destructors, so nothing is done to destroy members of built-in type."

              So if I have such a class:

            What the spec means is that no code is run to clean up int i. It simply ceases to exist. Its memory is part of Foo and whenever a Foo instance is released, then i goes with it.

            For pointers the same is true, the pointer itself will simply disappear (it's really just another number), but the pointer might point at something that needs to also be released. The compiler doesn't know if that is the case, so you have to write a destructor.

            This is why things like std::shared_ptr exist; they are clever pointers (aka 'smart') and the compiler does know if it points at something that needs to be released and will generate the correct code to do so. This is why you should always use smart pointers instead of 'naked' ones (like int *p).

            Welcome to dependency hell and breaking changes in libraries.

            This usually happens, when various lib bring in different version of same lib. In this case it is Jackson. java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; means: One lib probably require Jackson version, which has this method, but on class path is version, which does not yet have this funcion or got removed bcs was deprecated or renamed.

            In case like this is good to print dependency tree and check version of Jackson required in libs. And if possible use newer versions of requid libs.

            Solution: use libs, which use compatible versions of Jackson lib. No other shortcut possible.

            Lack of fairness in STM, why can't blocked threads be woken up in FIFO order?
            Asked 2021-Dec-08 at 11:15

            I'm revisiting the STM chapter of Marlow's book. There, it is stated that:

            When multiple threads block on an MVar, they are guaranteed to be woken up in FIFO order

            However, the same can't be done on the STM case:

            A transaction can block on an arbitrary condition, so the runtime doesn't know whether any individual transaction will be able to make progress after the TVar is changed; it must run the transaction to find out. Hence, when there are multiple transactions that might be unblocked, we have to run them all; after all, they might all be able to continue now.

            What I don't get is why from this it follows that

            Because the runtime has to run all the blocked transactions, there is no guarantee that threads will be unblocked in FIFO order ...

            I'd expect that even though we have to run all the transactions in an STM block, we can still wake the threads up in a FIFO order. So I guess I'm missing some important details.

            ...

            ANSWER

            Answered 2021-Dec-08 at 10:40

            The point of STM is to speculate: we try running all the transactions hoping that they do not conflict with one another (or perform a retry). When we do discover a conflict, we allow some transactions to commit, while making the conflicting ones to rollback.

            We could run only one transaction, wait for it to complete or to block, and then run another one, and so on, but doing so would amount to use a single "global lock", making the computation completely sequential.

            More technically, when threads are waiting on a MVar, those threads will progress on a very simple condition: the MVar becoming non empty. On wake up, a thread will take the value, making it empty. So, at most one thread can perform the take, and there's no point in waking more than one.

            By constrast, when threads are waiting because of STM, the condition is much more complex. Suppose they are waiting because they previously performed a retry, so they are waiting for some previously read TVar to be changed. When that happens, we can't really know which thread will block again unless we re-run its transaction. Unlike MVar, it is now possible that waking them all up will cause all of them to complete without conflict, so we try doing just that. In doing so we hope for many (if not all) to complete, and prepare to rollback again for those that do not.

            Consider this concrete STM example:

            How can I add arbitrary elements to the Table of Contents in Bookdown?

            I am making a book via bookdown. I know it is possible to omit headings from the Table of Contents by adding the attributes {.unlisted .unnumbered}, as shown in Section 4.18 of the R Markdown Cookbook. However, how can I add arbitrary content to the Table of Contents? If I only needed to add this for the PDF output, I could use (e.g.) the LaTeX command \addcontentsline, but I need this to show in the HTML contents sidebar as well.
