git push在HTTP/1.1之后挂起（哑巴）https 100继续

Question

我试图推动一些更改，但git push挂起。当我运行git push时，我看不到任何输出，也没有任何事情发生。 top没有任何活动，也没有任何发生的迹象。

我不控制git托管服务。我正在使用HTTPS网址。我相信托管服务使用哑HTTPS，而不是git的“智能HTTP”协议。在客户端，我使用Mac OS X，并且通过Homebrew安装了git 1.8.1.1（但使用包含在Xcode命令行工具中的git版本似乎没有什么区别）。注销并重新登录似乎没有帮助。我可以从一个不同的Linux机器上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挂客户端发出后PROPFIND请求时，从服务器获取一个HTTP/1.1 100 Continue响应，然后什么也没有发生：它只是卡住了。

我如何得到这个工作？有没有可以尝试的故障排除步骤？

我没有我的Mac OS X机上strace，我无法弄清楚如何使用dtruss哪些系统调用它挂在因为dtruss需要我是根目录，然后git push会以不同的方式工作。

更新：我已经在git 1.8.1.4和strace的Linux机器上重现了这一点。在后台运行strace显示类似于下面的东西它挂之前：

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... 

所以它似乎是挂期待从服务器接收的东西。

另外，我尝试过类似的跟踪与GIT_CURL_VERBOSE=1 git push -v上运行git 1.7.4.4旧的Linux机器，它具有相同前缀开始，然后从那里继续进行。在破碎机与新的git：

$ 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 

在旧机器与旧混帐，在它的所有工作：

$ 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/HEAD HTTP/1.1 
> PROPFIND /g_wagner/c79-s13/ HTTP/1.1

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

看着在两台机器上的全部跟踪，我不能查看有问题的PROPFIND请求（第二个PROPFIND）中发送的内容的差异：除User-Agent:标题外，两个请求看起来都是相同的。

Answer 1

我有问题，相同的症状（进程挂在HTTP/1.1 100 Continue）。

我发现了一个可以为我解决问题的提交：http-push.c: make CURLOPT_IOCTLDATA a usable pointer，它在GIT版本v2.0.3中可用。

显然用户没有在服务器上正确认证，即使它似乎是从通信。

问题很奇怪，因为对于你来说，它显示在一台机器上，但没有显示在安装了相同GIT版本的另一台机器上，对我而言，GIT在一个月的时间内停止工作，我无法真正说出原因。

或者，如果可能的话，使用允许其他协议的GIT服务提供程序：SSH或HTTPS，这些更好地被调试。

对于Windows用户，这是我拿上git-http-push 2.1.0-rc2版本（基于msysGit project instructions）

要反向移植到您的msysGit安装，解压缩，并在msysGit安装文件夹复制到/覆盖libexec\git-core\git-http-push.exe。

该问题已被举报here。

更新

最新msysGit（GIT-1.9.4-preview20140815）包含回迁修正错误。
