X Title: Introduce some clar helpers for child threads by ethomson · Pull Request #4010 · libgit2/libgit2

Description: When running in a child thread, we cannot clar_git_pass (or anything that will cause clar to longjmp to its error handler): The effect of a call to longjmp() where initialization of the jmp_buf structure was not performed in the calling thread is undefined. Instead, provide some helpers to set up an error context in the child thread that the clar execution thread can then restore and abort when safe. Use this for the threads::refdb test so that it errors gracefully, instead of crashing. Obviously this does not fix the underlying problem in thethreads::refdb test, but it does make it easier to reason about.
