我正在尝试为 Phabricator 建立一个良好的工作流程，并且最近对我们的测试项目进行了一些更改以解决一些问题。我做了一些更改，但忘记将它们放在自己的功能分支中。所有更改都未提交给 git。我继续创建了适用于我所做的更改并提交它们的功能分支。我以为我可以切换到每个分支并arc diff为他们创建代码审查（我仍然认为我可以做到这一点）。但是，当我arc diff在当前签出的分支上执行时，该命令永远不会完成。为了看看发生了什么，我跑了arc diff --trace。输出如下。正如您所猜测的那样，它通过了提交消息规范（在我的情况下是通过 Notepad++），然后完全死在[26] git diff线（我所说的“死”是指它挂起并且永远不会完成）。

我试过将git diff命令复制到一个单独的终端，它工作正常。我假设 PHP 的exec命令在本地可能有问题，所以我创建了一个快速的 2 行 PHP 文件来运行git diff命令……工作正常。我已经让该arc diff命令在该行运行了几个小时，但它没有完成。关于如何解决这个问题的任何想法？
更新
我忘了提到arc diff也挂在 a 上git commit --amend。
