            QUESTION

            Why does the implementation of std::any use a function pointer + function op codes, instead of a pointer to a virtual table + virtual calls?
            Asked 2022-Apr-08 at 15:31

            Both the GCC and LLVM implementations of std::any store a function pointer in the any object and call that function with an Op/Action argument to perform different operations. Here is an example of that function from LLVM:

            ...

            ANSWER

            Answered 2022-Apr-08 at 15:31

            Consider a typical use case of a std::any: You pass it around in your code, move it dozens of times, store it in a data structure and fetch it again later. In particular, you'll likely return it from functions a lot.

            As it is now, the pointer to the single "do everything" function is stored right next to the data in the any. Given that it's a fairly small type (16 bytes on GCC x86-64), any fits into a pair of registers. Now, if you return an any from a function, the pointer to the "do everything" function of the any is already in a register or on the stack! You can just jump directly to it without having to fetch anything from memory. Most likely, you didn't even have to touch memory at all: You know what type is in the any at the point you construct it, so the function pointer value is just a constant that's loaded into the appropriate register. Later, you use the value of that register as your jump target. This means there's no chance for misprediction of the jump because there is nothing to predict, the value is right there for the CPU to consume.

            In other words: The reason that you get the jump target for free with this implementation is that the CPU must have already touched the any in some way to obtain it in the first place, meaning that it already knows the jump target and can jump to it with no additional delay.

            That means there really is no indirection to speak of with the current implementation if the any is already "hot", which it will be most of the time, especially if it's used as a return value.

            On the other hand, if you use a table of function pointers somewhere in a read-only section (and let the any instance point to that instead), you'll have to go to memory (or cache) every single time you want to move or access it. The size of an any is still 16 bytes in this case but fetching values from memory is much, much slower than accessing a value in a register, especially if it's not in a cache. In a lot of cases, moving an any is as simple as copying its 16 bytes from one location to another, followed by zeroing out the original instance. This is pretty much free on any modern CPU. However, if you go the pointer table route, you'll have to fetch from memory every time, wait for the reads to complete, and then do the indirect call. Now consider that you'll often have to do a sequence of calls on the any (i.e. move, then destruct) and this will quickly add up. The problem is that you don't just get the address of the function you want to jump to for free every time you touch the any, the CPU has to fetch it explicitly. Indirect jumps to a value read from memory are quite expensive since the CPU can only retire the jump operation once the entire memory operation has finished. That doesn't just include fetching a value (which is potentially quite fast because of caches) but also address generation, store forwarding buffer lookup, TLB lookup, access validation, and potentially even page table walks. So even if the jump address is computed quickly, the jump won't retire for quite a long while. In general, "indirect-jump-to-address-from-memory" operations are among the worst things that can happen to a CPU's pipeline.

            TL;DR: As it is now, returning an any doesn't stall the CPU's pipeline (the jump target is already available in a register so the jump can retire pretty much immediately). With a table-based solution, returning an any will stall the pipeline twice: Once to fetch the address of the move function, then another time to fetch the destructor. This delays retirement of the jump quite a bit since it'll have to wait not only for the memory value but also for the TLB and access permission checks.

            Code memory accesses, on the other hand, aren't affected by this since the code is kept in microcode form anyway (in the µOp cache). Fetching and executing a few conditional branches in that switch statement is therefore quite fast (and even more so when the branch predictor gets things right, which it almost always does).

            I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github

            I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

            "The Developer of this app needs to update it to work with this version of iOS" pop up coming when launching Enterprise app for iOS 15
            Asked 2022-Jan-17 at 09:41

            We have an enterprise account, and till iOS 14 there were no issues, but as soon as user update their phones to iOS 15, they are getting this alert.

            The Developer of this app needs to update it to work with this version of iOS

            Now, this issue is coming only for enterprise apps running on iOS 15. I have done some research and found this article. https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format.

            In here it states that

            To check whether an app called MyApp.app has the new signature, you can use the

            codesign utility: % codesign -dv /path/to/MyApp.app

            Look in the output for a string such as CodeDirectory v=20500. For any value of v less than 20400, you need to re-sign your app.

            I did that and my output was indeed v=20400. I have signed the app using Xcode 12.5 running on Mac OS 11.2.3. I don't think Apple documents are correct for this. (I could be wrong)

            Can anyone please help and let me know, what exactly we need to do to get this issue fixed?

            If there is no -7= line (or it has no value) then your app does not include the DER entitlements and you will need to re-sign. You might need a new provisioning profile.

            Welcome @Backup Gov18,

            This is a documented issue.

            Note: Only one active BarCodeScanner preview is supported currently. When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use without issues.

            There is a workaround.

            Instead of conditionally rendering the component, you could render it inside another dedicated screen component.

            This way, after this new screen reads the barcode, you could navigate back to your first screen. Navigating back may unmount this new screen. You can force unmount if you need to.

            As you are using react-navigation, you had better use .pop() instead of goBack().

            Alternative

            You can also use expo-camera instead of expo-barcode-scanner. expo-camera does not have this issue. It also offers more options like flashlight/torch and switching cameras.

            GitHub Codespaces: how to set x86_64, AMD64, ARM64 platform?
            Asked 2021-Dec-17 at 21:44

            First, the question: is there a way to choose the platform (e.g. x86_64, AMD64, ARM64) for a GitHub Codespace?

            Here's what I've found so far:

            Attempt 1 (not working):

            From within GitHub.com, you can choose the "machine" for a Codespace, but the only options are RAM and disk size.

            Attempt 2 (EDIT: not working): devcontainer.json

            When you create a Codespace, you can specify options by creating a top-level .devcontainer folder with two files: devcontainer.json and Dockerfile

            Here you can customize runtimes, installed packages, etc., but the docs don't say anything about determining architecture...

            ...however, the VSCode docs for devcontainer.json has a runArgs option, which "accepts Docker CLI arguments"...

            and the Docker CLI docs on --platform say you should be able to pass --platform linux/amd64 or --platform linux/arm64, but...

            When I tried this, the Codespace would just hang, never finishing building.

            Attempt 3 (in progress): specify in Dockerfile

            This route seems the most promising, but it's all new to me (containerization, codespaces, docker). It's possible that Attempts 2 and 3 work in conjunction with one another. At this point, though, there are too many new moving pieces, and I need outside help.

            1. Does GitHub Codespaces support this?
            2. Would you pass it in the Dockerfile or devcontainer.json? How?
            3. How would you verify this, anyway? [Solved: dpkg --print-architecture or uname -a]
            4. For Windows, presumably you'd need a license (I didn't see anything on GitHub about pre-licensed codespaces) -- but that might be out of scope for the question.

            I received a response from GitHub support:

            The VM hosts for Codespaces are only x86_64 and we do not offer any ARM64 machines.

            So for now, setting the platform does nothing, or fails.

            But if they end up supporting multiple platforms, you should be able to (in Dockerfile)

            RUN --platform=arm64|amd64|x86-64 [image-name],

            Which is working for me in the non-cloud version of Docker.

            Original answer:

            I may have answered my own question

            In Dockerfile:

            I had RUN alpine

            changed to

            RUN --platform=linux/amd64 alpine

            or

            RUN --platform=linux/x86-64 alpine

            checked at the command line with

            uname -a to print the architecture.

            Still verifying, but seems promising. [EDIT: Nope]

            So, despite the above, I can only get GitHub codespaces to run x86-64. Nevertheless, the above syntax seems correct.

            A clue:

            In the logs that appear while the codespace is building, I saw target OS: x86

            Maybe GitHub just doesn't support other architectures yet. Still investigating.

            Avoid rerendering every component in list while updating only one in React
            Asked 2021-Dec-17 at 07:39

            I have a simple chat app using Firebase v9, with these components from parent to child in this hierarchical order: ChatSection, Chat, ChatLine, EditMessage.

            I have a custom hook named useChatService holding the list of messages in state, the hook is called in ChatSection, the hook returns the messages and I pass them from ChatSection in a prop to Chat, then I loop through messages and create a ChatLine component for every message.

            I can click the Edit button in front of each message, it shows the EditMessage component so I can edit the text, then when I press "Enter", the function updateMessage gets executed and updates the message in the db, but then every single ChatLine gets rerendered again, which is a problem as the list gets bigger.

            EDIT 2: I've completed the code to make a working example with Firebase v9 so you can visualize the rerenders I'm talking about after every (add, edit or delete) of a message. I'm using ReactDevTools Profiler to track rerenders.

            So here is my idea remove Messages from ChatSection and only add it in Chat.

            You already using useChatService in Chat so adding Messages there should be better.
