Concept ACK, obviously :) Thanks @vasild !

Mind also integrating #19845 (comment) as that change was unneeded?

Well, I left it as is because

template <typename E>
bool operator()(const E& e) const {

is more generic than

bool operator()(const std::runtime_error& e) const {

both work now but the former would also work if the exception does not inherit std::runtime_error.

I don't think the template function is required to make exception handling more generic for the following reasons:

  • all custom types in the project inherit from std::runtime_error
  • if this seems insufficient, the base std::exception type could be used

@vasild could you follow up here with @hebasto and @ajtowns comments, as this is a fairly straight-forward change.

For the PR title, maybe s/style/net, test/ per CONTRIBUTING.md. Feel free to ignore.

CentOS build uses pretty old gcc. Nice that CI caught that issue.

03525ea [Refactor] Clang-tidy and fix compiler error in HasReason class (Fuzzbawls)

Pull request description:

  Came across this compiler error when updating the [code coverage report](https://www.fuzzbawls.pw/pivx/regression-test-coverage/index.html). The server runs on CentOS 7 currently, which uses a fairly old (but still supported) version of gcc. Indeed, upstream also ran into this error (Ref: bitcoin#20033)

  Some older (but still supported) versions of gcc will throw an error
  when trying to convert from `std::ios_base::failure` to `std::runtime_error`.
  Use `std::exception` base type instead.

  Also apply clang-format to the class and remove the `cout`.

refactor: use constexpr and remove template
df99eb6 
Summary:
Minor follow-up to [[bitcoin/bitcoin#19845 | core#19845]] (D10720).

The template was thought to be needed to handle both `std::ios_base::failure` and `std::runtime_error`, but they both inherit `std:eexception` so it is not necessary.

This is a backport of [[bitcoin/bitcoin#20033 | core#20033]]

Test Plan: `ninja all check-all`
