Date: Mon, 27 Aug 2018 13:41:25 -0700 (PDT)	[thread overview]
Message-ID: <708b4550a115c3905de688dae8c479e7c2636d98.1535402479.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.25.git.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The rev-list command is critical to Git's functionality. Ensure it
works in the three commit-graph environments constructed in
t6600-test-reach.sh. Here are a few important types of rev-list
operations:

* Basic: git rev-list --topo-order HEAD
* Range: git rev-list --topo-order compare..HEAD
* Ancestry: git rev-list --topo-order --ancestry-path compare..HEAD
* Symmetric Difference: git rev-list --topo-order compare...HEAD
