  • Should You Be Scared of Unix Signals?
    8 projects | news.ycombinator.com | 16 Oct 2023
    > Libc is a lot more tricky about signals, since not all libc functions can be safely called from handlers.

    And this is a huge thing. People do all kinds of operations in signal handlers completely oblivious to the pitfalls. Pitfalls which often do not manifest, making it a great "it works for me" territory.

    I once raised a ticket on fluentbit[1] about it but they have abused signal handlers so thoroughly that I do not think they can mitigate the issue without a major rewriting of the signal and crash handling.
