GitHub Actions 意外的 bash 可读测试结果

Question

移动电源

我有一个 GitHub Actions 工作流程，它最近在我没有进行更改的情况下停止工作。错误：

==> ERROR: /etc/makepkg.conf not found.
    Aborting...

这是从运行# sudo -Eu builder makepkg --printsrcinfo。

• 来源
• 日志

日志的顺序似乎是错误的，但在较早的日志中是正确的（可能是由于ls -l输出量大）。

此错误的来源似乎是libmakepkg/util/config.sh.in：

==> ERROR: /etc/makepkg.conf not found.
    Aborting...

我在入口点脚本中添加了以下内容：

    # Source the config file; fail if it is not found
    if [[ -r $MAKEPKG_CONF ]]; then
        source_safe "$MAKEPKG_CONF"
    else
        error "$(gettext "%s not found.")" "$MAKEPKG_CONF"
        plainerr "$(gettext "Aborting...")"
        exit $E_CONFIG_ERROR
    fi

该builder用户在创建build.sh：

echo "Writing SRCINFO..."

# Debug
echo "---"
ls -l /
echo "---"
ls -l /etc
echo "---"
sudo -Eu builder cat /etc/makepkg.conf
echo "---"
sudo -Eu builder /bin/bash -c "[[ -r "/etc/makepkg.conf" ]] && echo 1 || echo 0"
echo "---"

sudo -Eu builder makepkg --printsrcinfo > .SRCINFO

我有：

==> ERROR: /etc/makepkg.conf not found.
    Aborting...

( 的内容/etc/makepkg.conf被连接。)

我也意外地[[ -r "/etc/makepkg.conf" ]] && echo 1 || echo 0（以 root 身份）做了，我也得到了0.

文件怎么可能不可读但我可以 cat？我还尝试在本地容器中运行完全相同的命令，但无法重现此问题，但自 GitHub Actions 启动以来，每次运行都会发生这种情况。

这让我认为 Actions 设置引起了问题，但似乎没有什么奇怪的：

/usr/bin/docker build -t 442333:35a065f0b9f356b32f2852ba2f6b7296 -f "/home/runner/work/visual-studio-code-insiders-arch/visual-studio-code-insiders-arch/./.github/actions/pkg/Dockerfile" "/home/runner/work/visual-studio-code-insiders-arch/visual-studio-code-insiders-arch/.github/actions/pkg"

感谢您分享这个。我有完全相同的问题。

我在我的中添加了以下内容Dockerfile

RUN sed -i 's/\tif \[\[ -r $MAKEPKG_CONF \]\]; then/\tif \[\[ -f $MAKEPKG_CONF \]\]; then/' /usr/share/makepkg/util/config.sh

它取代了检查读取权限 ( -r) 来检查文件是否存在以及是否是常规文件 ( -f)。

现在我的 github 操作克服了这个特定位置，但在下一次检查时失败：

==> ERROR: You do not have write permission for the directory $BUILDDIR (/tmp/aurutils).
    Aborting...

这不是一个解决方案，也没有回答根本问题，但我希望它无论如何都能有所帮助。
