新创建的存储库中的Arc diff抛出异常'hg:parse error:empty query'

问题描述 投票:1回答:1

在新创建的Mercurial存储库中使用arc diff时,我遇到异常。

首先,我通过自我托管的phabricator服务器创建了一个新的Mercurial存储库。然后,我将空项目克隆到我的本地机器(macOS Mojave 10.14.2)。在我的项目中,我根据.arcconfig创建了一个the doc文件,其中包含以下内容(用虚拟链接替换实际uri仅用于说明):

{
    "phabricator.uri": "http://example.com"
}

然后我使用hg add上传新文件并运行arc diff --trace

 ARGV  '/usr/local/arcanist/bin/../scripts/arcanist.php' 'diff' '--trace'

因此,导致异常的是hg status --rev '' --rev tip,看起来它是一个带有无效参数的命令。我不确定为什么会这样。我的同事也在他的OSX机器上复制了这个问题。

mercurial arcanist

事实证明,当项目为空时会发生此错误。在我使用hg push将某些东西推送到存储库后,它可以工作。
