Git - 缓慢获取 - 凭证管理器主机提供程序

Question

I have noticed that git operations slowed down recently, it might be related to the upgrade of git and using credential-manager-core instead of credential-manager, I've tried to diagnose the issue using GCM_TRACE=1 git fetch , looks like I可能弄乱了我的配置：

[GetProviderAsync] Checking against 3 host providers registered with priority 'Normal'.

我的同事没有看到这样的行，并且只检查了一个主机提供商。 如何更改 git 凭据管理器使用的主机提供程序的配置？

更新：使用便携式版本的 git 没有帮助，请在下面跟踪 output：

注册主机提供商的数量似乎很可疑，但我不知道如何更改。 此外 - 在每次提取时存储凭据似乎不是一件有效的事情。

更新 2：切换到 SSH 授权并没有太大帮助，因此延迟的根本原因与 GCM 无关。 我会进行更多调查，可能会结束这个问题。

Answer 1

通过以下方式测试这是否链接到您当前的 Git 以进行 Windows安装：

• 在新文件夹（ C:\git ）中解压缩便携式版本（如PortableGit-2.31.1-64-bit.7z.exe ，可自动提取）
• 在 CMD session 中设置自定义简化%PATH%

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%GH%\mingw64\libexec\git-core;%PATH%

• 检查git fetch问题是否仍然存在

这样，您就不会干扰您当前的设置，并将您的测试限制在单个 CMD session。

当我遇到类似问题时，我没有像您那样使用 git 跟踪，但是每次我进行提取时都会收到 3 条“正在检测主机提供程序”消息。 我在 git 2.33.1.windows.1 之前没有使用 https 遥控器。 （2.33.1 显然停止允许 rsa/sha-1 密钥，我在故障排除时切换到个人访问令牌。）我已经在使用凭证管理器核心，所以我的解决方案是向 .gitconfig 添加一个 credential.provider 设置，告诉它我我正在连接到 bitbucket 服务器。

[credential]
    helper = manager-core
[credential "https://example.com"]
    provider = bitbucket

这样做之后，我没有收到任何“检测主机提供程序”消息，并且 git 获取现在运行得更快。 https://github.com/microsoft/Git-Credential-Manager-Core/blob/main/docs/configuration.md
