            I'm not terribly familiar with your stack, so this is a high-level answer to hit on your "Why". There WILL be a more specific answer for you, somewhere down the pipe (e.g. someone that can confirm whether this thread is relevant).

            While I'm no Spring Daisy (or Spring dev), you bind an expression to filmMono that resolves as the query select film.* from film..... You reference that expression four times, and it's resolved four times, in separate contexts. The ordering of the statements is likely a partially-successful attempt by the lib author to lazily evaluate the expression that you bound locally, such that it's able to batch the four accidentally identical queries. You most likely resolved this by collecting into an actual container, and then mapping on that container instead of the expression bound to filmMono.

            In general, this situation is because the options available to library authors aren't good when the language doesn't natively support lazy evaluation. Because any operation might alter the dataset, the library author has to choose between:

            • A, construct just enough scaffolding to fully record all resources needed, copy the dataset for any operations that need to mutate records in some way, and hope that they can detect any edge-cases that might leak the scaffolding when the resolved dataset was expected (getting this right is...hard).
            • B, resolve each level of mapping as a query, for each context it appears in, lest any operations mutate the dataset in ways that might surprise the integrator (e.g. you).
            • C, as above, except instead of duplicating the original request, just duplicate the every step. Pass-by-copy gets real painful real fast on the JVM, and languages like Clojure and Scala handle this by just making the dev be very specific about whether they want to mutate in-place, or copy then mutate.

            In your case, B made the most sense to the folks that wrote that lib. In fact, they apparently got close enough to A that they were able to batch all the queries that were produced by resolving the expression bound to filmMono (which are only accidentally identical), so color me a bit impressed.

            Many access patterns can be rewritten to optimize for the resulting queries instead. Your milage may vary...wildly. Getting familiar with raw SQL, or else a special-purpose language like GraphQL, can give much more consistent results than relational mappers, but I'm ever more appreciative of good IDE support, and mixing domains like that often means giving up auto-complete, context highlighting, lang-server solution-proofs and linting.

            Given that the scope of the question was "why did this happen?", even noting my lack of familiarity with your stack, the answer is "lazy evaluation in a language that doesn't natively support it is really hard."

            What do the values for gitlab's predefiner variable CI_PIPELINE_SOURCE mean?
            Asked 2021-Oct-27 at 08:17

            In the gitlab documentation you find a list of predefined variables HERE, where the variable CI_PIPELINE_SOURCE is explained to have the possible values "push, web, schedule, api, external, chat, webide, merge_request_event, external_pull_request_event, parent_pipeline, trigger, or pipeline."

            However, it is not explained, what they mean.

            • push: When you push something to a branch?
            • web: When you trigger a pipeline from the web GUI?
            • schedule: When a pipeline is triggered by a schedule
            • api: When the pipeline is triggered by an API request
            • external: ???
            • chat: ???
            • webide: ???
            • merge_request_event: Seems to be triggered when a merge request is created. Does not trigger when a change is actually merged
            • external_pull_request_event: ???
            • parent_pipeline: ???
            • trigger: ???
            • pipeline: another pipeline?

            If someone knows where the documentation for that is hiding, I appreciate if you can let me know where to find it.

            In addition, how can I figure out when some changes are actually merged into a branch? How can I trigger a pipeline in that event?

            Regarding your first set of questions, i have to point you forward to the gitlab CI Documentation and the rules:if section. They have their a good explanation of the states and also some addtion - i am just screenshoting this, so people can relate to it in the future if the link gets outdated:

            Regarding your additional question:

            A merge is a push. We do not check on some branches for CI_PIPELINE_SOURCE but for the branch name and do checks simply against that like:

            React: accessing internal operation queue of React
            Asked 2021-Oct-08 at 12:21

            React collects operations(like DOM operations such 'ADD','REPLACE','REMOVE' and more) so they could execute them in batch in one shot at the end of each render.

            for example, setState call inside React component is scheduled to the end of the construction of this React tree by adding this operation to the operation queue. then react will go over this queue and will decide what changes need to be made to the DOM.

            React will decide whether or not to call another render based on whether or not the operation queue is empty or not.

            more info on this awesome tutorial which summarizes the basics of how React works internally.

            I need access to this queue to decide whether or not the current render was the last for a very custom React component. (YES maybe I can avoid it but currently, this is my requirement)
            the access must be from inside of this component.

            my check will be called from the lastest useEffect which is after the render ends and the DOM was updated and is the latest lifecycle event, so if the operation queue is empty there will be no more renders for sure. (here nice article explains and demonstrates the order of hook calls)

            couldn't find any public API, but a workaround would also be acceptable. (forking and editing React is not a workaround)

            this src file is probably the main logic to this queue. and this is the type of the actual queue. however this is the source code and this queue is not exported in the built versions of react(neither development or production build)

            so, is there a way to access the internal operation queue of React?



            Answered 2021-Oct-08 at 12:21
            EDIT - Warning

            this is for educational purposes only - do not use it on production! this approach is not safe based on React core team member - I've already asked. it could be safe if you plan to use a fixed version of React without upgrading later.

            ####### END OF EDIT #######


            so after many many hours digging into React codebase I finally wrote a hook that tells if any update is currently scheduled.

            Note: would work for function components only, and this hook is not well tested.

            you can see some internal state of React by the undocumented __SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED property. this prop holds ReactCurrentOwner which is basically a reference to the current component that is being constructed.

            You could use DAG params to achieve what you are looking for:

            params (dict) – a dictionary of DAG level parameters that are made accessible in templates, namespaced under params. These params can be overridden at the task level.

            Confusion regarding the Blocking of "peer threads" when a user-level thread blocks
            Asked 2021-Sep-07 at 10:40

            I was reading about differences between threads and processes, and literally everywhere online, one difference is commonly written without much explanation:

            If a process gets blocked, remaining processes can continue execution. If a user level thread gets blocked, all of its peer threads also get blocked.

            It doesn't make any sense to me. What would be the sense of concurrency if a scheduler cannot switch between a blocked thread and a ready/runnable thread. The reason given is that since the OS doesn't differentiate between the various threads of a given parent process, it blocks all of them at once.

            I find it very unconvincing, since all modern OS have thread control blocks with a thread ID, even if it is valid only within the memory space of the parent process. Like the example given in Galvin's Operating Systems book, I wouldn't want the thread which is handling my typing to be blocked if the spell checking thread cannot connect to some online dictionary, perhaps.

            Either I am understanding this concept wrong, or all these websites have just copied some old thread differences over the years. Moreover, I cannot find this statement in books, like Galvin's or maybe in William Stalling's COA book where threads have been discussed.

            These are resouces where I found the statements:

            There is a difference between kernel-level and user-level threads. In simple words:

            • Kernel-level threads: Threads that are managed by the operating system, including scheduling. They are what is executed on the processor. That's what probably most of us think of threads.
            • User-level threads: Threads that are managed by the program itself. They are also called fibers or coroutines in some contexts. In contrast to kernel-level threads, they need to "yield the execution", i.e. switching from one user-level to another user-level thread is done explicitly by the program. User-level threads are mapped to kernel-level threads.

            As user-level threads need to be mapped to kernel-level threads, you need to choose a suiteable mapping. You could map each user-level to a separate kernel-level thread. You could also map many user-level to one kernel-level thread. In the latter mapping, you let multiple concurrent execution paths be executed by a single thread "as we know it". If one of those paths blocks, recall that user-level threads need to yield the execution, then the executing (kernel-level) thread blocks, which causes all other assigned paths to also be effectively blocked. I think, this is what the statement refers to. FYI: In Java, user-level threads – the multithreading you do in your programs – are mapped to kernel-level threads by the JVM, i.e. the runtime system.

            Local notification sound not playing while app in background - Swift
            Asked 2021-Aug-11 at 06:04

            I'm making an alarm clock app, and I have confirmed that my alarm notifications are being triggered correctly, but the sound does not always play as I expect.

            For instance, when the phone is not in silent mode, the notification plays the sound sucessfully (ok, great!). However, when the phone is in silent mode, the sound does not play, even though the app is still running in the background (not so great...).

            I understand that silent mode is supposed to silence all notification sounds, BUT I've downloaded other alarm clock apps from the App Store (like Alarmy), and they are somehow able to get their notification sounds to play even if the phone is on silent mode, as long as the app is still running in the background. Only when the app is fully exited will the silent mode take effect.

            Does anyone know how to achieve this result? Is there some setting or option that I need to declare either in my code or plist file? I've scoured the internet but haven't found anything for this particular issue...

            Answered 2021-Aug-11 at 06:04

            So I've discovered something.

            As the question is stated, it is not currently possible to play sound in a local notification when the phone is on silent mode.

            However, great news!

            There is actually a different way to achieve the same result; and it's how apps like Alarmy do it.

            Note: I (FINALLY) discovered this solution from this wonderful SO answer, but I'll summarize it here for reference.

            In short, the local notification will not be playing the sound, but instead, the app will play it (while in the background).


            1. You must enable the app to play sound in the background. To do this, navigate to your .plist file and add the String value App plays audio or streams audio/video using AirPlay to the array key Required background modes. (This can also be achieved in your app's Capabilities - it does the same thing).

            2. In your App Delegate, set your AVAudioSession's category to .playBack so sound will still play even when the phone is locked or in the background.
