I am using check_memory plugin to check available memory on my machine. I have specified the warning and critical limits, but this plugin is not displaying it while other plugins like check_mem displays it. Any help is appreciated.
I tried a lot for displaying the warning and critical conditions for this plugin but it didnt worked. What I did is now I have updated plugin code. In code the : is appended at the end of warning and critical conditions I removed them and also removed the unit of measurement and it started displaying values in bytes.

Can someone please explain what the point is of source maps? Because as I see it, my concatenated and minified file gets loaded (talking about JavaScript), alongside 100+ modules. How is this not affecting performance when I'm loading twice the size as before?
The point of a source map is that you can run minified Javascript or transpiled Javascript (which is not particularly readable in a debugger by itself), but when you open the debugger, the source map is loaded by the debugger and it gives you a readable form of your source for debugging purposes. The source map is not loaded if the browser is not configured for source map debugging.
Source maps are also extremely useful if you are transpiling code from something like TypeScript or ES6 down to ES5 Javascript so you can see the actual code that you wrote originally in the debugger rather than only the transpiled and minified output.
The alternative before the days of source maps was to have separate versions of your site or options on your site that would load non-minified JS so that you could debug with normal symbols, but this of course isn't actually debugging the exact same code so even then, this could still leave you having to try to debug minified code.
You can read here about how source maps are enabled in the Chrome debugger. If you're watching what is downloaded by the browser, then make sure that you are using a browser that does not have source maps enabled when checking if they are downloaded.
Because you only load the sourcemap when you open the debugger.
Actual users, who don't open the debugger, still get the benefit of the minification.
A source map is a developer tool. It's practical to know the original source when an error occurs within minified source, so you can track down the source of the error.
Source maps are thus only loaded by debuggers, and will not be loaded by default. However, you should consider disabling source maps for production environments, because debug data usually shouldn't be on production environments: for performance and (more importantly) security reasons
I'm working on a web project with reactjs. For some time, whenever I run my code on vscode, the browser shows me a nice blank page. I don't know why because it didn't happen before and I didn't make any changes to the source code. I read an article on the web that said it was due to an error that occurred in my code. But despite that, I don't understand because even before this blank page problem, I often had errors in my code and react showed me on the web page instead of the application a black page with the details and the lines errors occurred. But now nothing, just a blank page and in the command line, no errors are reported to me, just warnings.After reading an article on the internet, I realized that I could use error bounds on components to prevent this, but since for some reason
efficiency I couldn't use error limits on all my components, so I had to use it on the element responsible for the crash. But the problem is that I don't know which element is responsible for this and vscode doesn't show me information about the crash. Still, according to the official documentation, vscode should give details of my page crash as well as the location of the error and I'm using a react version greater than 16. I don't know what to do or what resource to use. So I ask for your help. Thanks!
I like to use the console to debug my React-Native (0.63.4) application.
For some time now, React seems to automatically add a stack trace to my console.warn and console.error logs.
For example, the logs look like this in the Chrome debugger:
As you can see in the screenshot, the log message is actually collapsed (see small arrow in the upper left). So I assume that the stacktrace is added via some function in React in addition to the "normal" stacktrace. When I expand the message, the "normal" stacktrace of the Chrome debugger appears below, e.g.
:
I'm sure this feature might be quite helpful, but the logs become completely illegible and confusing if they contain a few warnings. Therefore My question, does anyone know how to disable this feature?
Actually, The Debuggers are mainly used to debug the app or trace the issue if we are facing anything in code.
So If there is an issue then we can get the proper stack of the issue to know from where the exact mistake is with which we can solve the problems in our code.
For this reason, we can accept that there will be no way to manage it manually.
Also, there is no manual documentation to manage the logs from React Native.
I get a strange Error Message during the Code-Generation Process in STM CubeIDE for a STM32F4 target:
The Details:
I am using STM CubeIDE for an embedded Project with an STM32F405 Microcontroller and I have added the CMSIS Package 5.7.0 to the project, because i need some of the DSP functions. I have allready done this before and never experienced such an error message.
The message pops up during the Code-Generation process, after changing something in the Hardware-Setup with the (built in) CubeMX. It occurs two times during the Code Generation process. I can click on "OK" and it does NOT interrupt the Code Generation process, which seems to finish successfully. I can also compile the project without errors and it seems to work ok.
The Question:
Even though it seems to work properly, I'd like to know: what is this, where does it come from, and what can I do to solve this? I'm affraid that might lead to some unpleasant sleeping bugs or other nasty stuff ...
Has anyone experienced anything simlilar and has an explanation or even a solution for this?
Hint: I have recently update to CubeIDE 1.6.0 - maybe this is a Bug in CubeIDE and not in CMSIS?
What I've done:
I tried to google that, with the keywords:
"SliDtzliTZ&" and the "LogicalParser:syntax error detected in expression for ARM.CMSIS.5.7.0" but did not get any usefull results. Next step was to post the question here ...
Thank you in advance,
Chris
This problem happens with release version 5.7.0. Using any older version available in the official repository solves the problem.
I'm using 5.6.0 now and all is fine.
Edit: Problem persists on 5.8.0.
I noticed that when I don't use brackets in some parts of my code (condiditional if else) I can't properly debug it in google chrome. This also happens in edge
Does anybody know what is it due to?
The code that you see is the source code written in JSX. Browsers can't run JSX, they can run Javascript. Your tool chain transpiles the JSX to Javascript and provides a source map that tries to allow you to put breakpoints in the original code while stopping at the execution point in the generated code. Sometimes the mapping is not exact and precise enough to allow you to pause on the exact same spot. That seems to be the case in this instance.
