Pull request description:

  Some uses of non-threadsafe `strerror` have snuck into the code since they were removed in #4152. Add a wrapper `SysErrorString` for thread-safe strerror alternatives (with code from `NetworkErrorString`) and replace all uses of `strerror` with this.

  Edit: I've also added a commit that refactors the code so that buf[] is never read at all if the function fails, making some fragile-looking code unnecessary.

  Edit2: from the linux manpage:
  ```

  As the function can be called from any thread at any time, using a non-thread-safe function is unacceptable.

This folder contains lint scripts.

check-doc.py

Check for missing documentation of command line options.

commit-script-check.sh

Verification of scripted diffs. Scripted diffs are only assumed to run on the latest LTS release of Ubuntu. Running them on other operating systems might require installing GNU tools, such as GNU sed.

git-subtree-check.sh

Run this script from the root of the repository to verify that a subtree matches the contents of the commit it claims to have been updated to.

Usage: test/lint/git-subtree-check.sh [-r] DIR [COMMIT]
       test/lint/git-subtree-check.sh -?
  • DIR is the prefix within the repository to check.
  • COMMIT is the commit to check, if it is not provided, HEAD will be used.
  • -r checks that subtree commit is present in repository.

To do a full check with -r, make sure that you have fetched the upstream repository branch in which the subtree is maintained:

To do so, add the upstream repository as remote:

git remote add --fetch secp256k1 https://github.com/bitcoin-core/secp256k1.git

lint-all.py

Calls other scripts with the lint- prefix.
