kandi X-RAY | trace Summary

trace is a JavaScript library typically used in User Interface, Frontend Framework, Ethereum, React applications. trace has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A transparent supply chain management platform with end users in mind. Trace is a decentralized application based on the Ethereum blockchain aiming to let consumers see the data behind the products they buy every day. It currently allows industry experts to add products to the app, as well as create certifications that can be added to products. A mobile companion app (not developed yet) would allow scanning Trace QR codes placed on the actual products to see the data on-premise (e.g. at the grocery store). Keep in mind that this is a proof of concept. It is not production ready by any means. However, we do invite you to play around with the project and use it as you see fit. There are some rough edges, so we definitely appreciate your help in improving the platform. This project was developed under the supervision of Bessam Abdulrazak, director of the Ambient Intelligence Lab at Université de Sherbrooke. Made using the Truffle toolkit, React.js, Redux, and Webpack. Logo design by Laurence Mailhiot.

            Make sure your .gitignore is in the parent folder of .angular.
            In that .gitignore file, a simple .angular/cache/ should be enough to ignore that subfolder content.

            Asked 2022-Mar-25 at 06:14

            I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

            In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

            I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

            I figured out that these lines in our build.gradle file are the origin of the problem.

            This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

            As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

            Are you using the @react-native-community/netinfo library? You need to refresh this library if you are using it.

            After updating or uninstalling and reinstalling the netinfo library it will work.

            Visual Studio Code "Error while fetching extensions. XHR failed"
            Asked 2022-Mar-13 at 12:38

            This problem started a few weeks ago, when I started using NordVPN on my laptop. When I try to search for an extension and even when trying to download through the marketplace I get this error:

            EDIT: Just noticed another thing that might indicate to what's causing the issue. When I open VSCode and go to developer tools I get this error messege (before even doing anything):

            "(node:19368) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.(Use Code --trace-deprecation ... to show where the warning was created)"

            The only partial solution I found so far was to manually download and install extensions.

            I've checked similar question here and in other places online, but I didn't find a way to fix this. So far I've tried:

            1. Flushing my DNS cache and setting it to google's DNS server.
            2. Disabling the VPN on my laptop and restarting VS Code.
            3. Clearing the Extension search results.
            4. Disabling all the extensions currently running.

            I'm using a laptop running Windows 10. Any other possible solutions I haven't tried?

            Error when trying to run my React Native app on Android
            Asked 2022-Mar-06 at 07:58

            I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.

            I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install and then I ended up with the exact same error message as I had in the original project when I run react-native run-android.

            I've hit this same issue and have temporarily resolved it by uninstalling react-native-video (npm uninstall --save react-native-video). That's not a great answer as I need that component, but I don't have a full solution yet. I think somehow com.yqritc:android-scalablevideoview:1.0.4. is required by react-native-video but has gotten lost or removed. Other thoughts are welcome.

            What is 'serviceability memory category' of Native Memory Tracking?
            Asked 2022-Jan-17 at 13:38

            I have an java app (JDK13) running in a docker container. Recently I moved the app to JDK17 (OpenJDK17) and found a gradual increase of memory usage by docker container.

            During investigation I found that the 'serviceability memory category' NMT grows constantly (15mb per an hour). I checked the page https://docs.oracle.com/en/java/javase/17/troubleshoot/diagnostic-tools.html#GUID-5EF7BB07-C903-4EBD-A9C2-EC0E44048D37 but this category is not mentioned there.

            Could anyone explain what this serviceability category means and what can cause such gradual increase? Also there are some additional new memory categories comparing to JDK13. Maybe someone knows where I can read details about them.

            Here is the result of command jcmd 1 VM.native_memory summary

            ANSWER

            Answered 2022-Jan-17 at 13:38

            Unfortunately (?), the easiest way to know for sure what those categories map to is to look at OpenJDK source code. The NMT tag you are looking for is mtServiceability. This would show that "serviceability" are basically diagnostic interfaces in JDK/JVM: JVMTI, heap dumps, etc.

            But the same kind of thing is clear from observing that stack trace sample you are showing mentions ThreadStackTrace::dump_stack_at_safepoint -- that is something that dumps the thread information, for example for jstack, heap dump, etc. If you have a suspicion for the memory leak in that code, you might try to build a MCVE demonstrating it, and submitting the bug against OpenJDK, or showing it to a fellow OpenJDK developer. You probably know better what your application is doing to cause thread dumps, focus there.

            That being said, I don't see any obvious memory leaks in StackFrameInfo, neither can I reproduce any leak with stress tests, so maybe what you are seeing is "just" thread dumping over the larger and larger thread stacks. Or you capture it when thread dump is happening. Or... It is hard to say without the MCVE.

            Update: After playing with MCVE, I realized that it reproduces with 17.0.1, but not with either mainline development JDK, or JDK 18 EA, or JDK 17.0.2 EA. I tested with 17.0.2 EA before, so was not seeing it, dang. Bisection between 17.0.1 and 17.0.2 EA shows it was fixed with JDK-8273902 backport. 17.0.2 releases this week, so the bug should disappear after you upgrade.
