Question

我正在尝试推送一些更改，但git push会挂起。当我运行git push时，我看不到输出，似乎没有发生任何事情。 top中没有任何活动，也没有发生任何事情的迹象。

我不控制git托管服务。我正在使用HTTPS URL。我相信托管服务使用的是哑的HTTPS，而不是git的“智能HTTP”协议。在客户端，我使用Mac OS X，并且我已经通过Homebrew安装了git 1.8.1.1（但是使用Xcode的命令行工具中包含的git版本似乎没有什么区别）。注销并重新登录似乎没有帮助。我可以从另一个Linux盒子中拉出并推送到这个托管服务/存储库。

下面是一些调试输出，显示git push在客户端发出PROPFIND请求后挂起，从服务器获得HTTP/1.1 100 Continue响应，然后没有任何反应：它只是卡住了。

我如何让这个工作？我可以尝试任何故障排除步骤吗？

我的Mac OS X计算机上没有strace，我无法弄清楚如何使用dtruss来查看它挂起的系统调用因为dtruss要求我成为root用户，然后git push将以不同的方式工作。

更新：我在带有git 1.8.1.4和strace的Linux机器上重现了这个。运行strace在挂起之前会显示如下内容：

sendto(4, <redacted>..., 314, 0, NULL, 0) = 314
recvfrom(4, "\27\3\1\0000", 5, 0, NULL, NULL) = 5
recvfrom(4, "E\202\271\21\236p\200\346\374\3641\355\t\275\rLi\202T)\326\271l/\351\f\357\2769Jb\22"..., 48, 0, NULL, NULL) = 48
select(5, [4], [4], [], {0, 729000}) = 1 (out [4], left {0, 728997})
poll([{fd=4, events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}, {fd=4, events=POLLOUT|POLLWRNORM}], 2, 0) = 1 ([{fd=4, revents=POLLOUT|POLLWRNORM}])
select(5, [4], [], [], {0, 729000}) = 0 (Timeout)
poll([{fd=4, events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}], 1, 0) = 0 (Timeout)
...last 2 lines repeat infinitely...

因此，似乎希望从服务器接收内容。

此外，我在运行git 1.7.4.4的较旧的Linux机器上尝试了与GIT_CURL_VERBOSE=1 git push -v类似的跟踪，它以相同的前缀开始，然后从那里继续。在使用较新git的破碎机器上：

$ grep '^> [A-Z]' git-1.8.1.1-trace.stderr
> GET /redacted/redacted/info/refs?service=git-receive-pack HTTP/1.1
> GET /redacted/redacted/info/refs?service=git-receive-pack HTTP/1.1
> GET /redacted/redacted/HEAD HTTP/1.1
> PROPFIND /redacted/redacted/ HTTP/1.1
> PROPFIND /redacted/redacted/ HTTP/1.1

在旧机器上使用较旧的git，它们都在工作：

$ grep '^> [A-Z]' git-1.7.4.4-trace.stderr
> GET /g_wagner/c79-s13/info/refs?service=git-receive-pack HTTP/1.1
> GET /g_wagner/c79-s13/info/refs?service=git-receive-pack HTTP/1.1

> GET /g_wagner/c79-s13/objects/info/packs HTTP/1.1
...
> UNLOCK /g_wagner/c79-s13/info/refs HTTP/1.1

查看两台计算机上的完整跟踪，我看不出有问题的PROPFIND请求（第二个PROPFIND）发送的内容有什么不同：两个请求看起来都是相同的，User-Agent:标题除外

Answer 1

我遇到了相同症状的问题（进程挂起HTTP/1.1 100 Continue）。

我找到了一个可以解决问题的提交：http-push.c: make CURLOPT_IOCTLDATA a usable pointer，它可以在 GIT版本v2.0.3 中找到。

显然，用户未在服务器上正确进行身份验证，即使从通信中看起来也是如此。

问题很奇怪，因为对于你而言，它出现在一台机器上而不是另一台机器上安装了相同的GIT版本，对我来说，GIT刚刚在一个月内停止工作，我无法确切地说出原因是什么。 / p>

或者，如果可能，请使用允许其他协议的GIT服务提供商：SSH或HTTPS，这些协议要好得多。

对于Windows用户，这是我对git-http-push 2.1.0-rc2构建的看法（基于msysGit project instructions）

要向后移植到 msysGit 安装，请将其解压缩并在msysGit安装文件夹中复制到/覆盖libexec\git-core\git-http-push.exe。

已报告此问题here。

<强>更新

最新msysGit（Git-1.9.4-preview20140815）包含backported错误修正。

在HTTP / 1.1 100继续之后，git push挂起（哑）https
