From c19a490e37181de8fa94ae1074af4b9f9a518f95 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 16 Apr 2013 15:46:22 -0400 Subject: usage: allow pluggable die-recursion checks When any git code calls die or die_errno, we use a counter to detect recursion into the die functions from any of the helper functions. However, such a simple counter is not good enough for threaded programs, which may call die from a sub-thread, killing only the sub-thread (but incrementing the counter for everyone). Rather than try to deal with threads ourselves here, let's just allow callers to plug in their own recursion-detection function. This is similar to how we handle the die routine (the caller plugs in a die routine which may kill only the sub-thread).
