favicons favicons seem to never call back in some cases

I have the following code

favicons(icon, config, async (error, response) => {
  if (error) {
    console.error(error);
  } else {
    console.log(response);
  }
});

and sometime, the callback never get called. I have to stop the process any idea ?

Because it is async, we don't support it

Aug 26 '20 13:08 alexander-akait

What do you mean ?

Aug 26 '20 16:08 wighawag

callback is async and we don't use await callback() in code

Aug 26 '20 16:08 alexander-akait

oh i see, but that is not the issue. what I mean is that the callback never get called (removing async here will not change that)

@wighawag please create reproducible test repo

Aug 27 '20 12:08 alexander-akait

In this repo https://github.com/wighawag/purple-warlock the script web/_build/generate.ts call favicon and sometime favicon never call the callback. I work around this by adding a timeout and try again.

I'm actually having the same issue and my callback is completely sync (saying that looking at the code that wouldn't really make a difference). I think it was not happening on V5.4.1

I created this super simple example and I explained how to make it fail. I also added the module "why-is-node-running" to it and like that it's possible to see the handles that are holding the process https://github.com/jdmerinor/testFavicons

@alexander-akait On the repo mentioned above I added also the logs that I got when it failed and thew handles taken, I'm adding those here for reference, this was basically my output:

I think this is why the program hangs when I use favicons-webpack-plugin.

Mar 16 '21 07:03 zhnoah

Is there an update on this? With the new version of Node JS it gets stuck even worse... now not even with a retry it will be able to come back to life :(

Same thing happens to me. Randomly stalls to the same [Favicons] Images:composite: Compositing favicon on 64x64 canvas with offset 0... line.

Windows 11 and Node v16.14.2

@peksipatongeis may you try to reproduce the issue with favicons 7.0.0-beta.4?

@peksipatongeis may you try to reproduce the issue with favicons 7.0.0-beta.4?

Tested with [email protected] and it gets similarly stuck as it did with v6.

There are 5 handle(s) keeping the process running

Edit. I wonder if this issue is similar to what we have in here?

I was not able to reproduce this on Linux, but somehow this happens from time to time on Windows virtual machine. I am afraid, this is some sort of low-level concurrency issue with Sharp and specific to Windows.
