通过桑巴Git不能获取/添加/提交了 [英] Git over samba cannot fetch/add/commit anymore

问题描述

我曾多次使用过git trough samba，没有任何问题。

然而，在最后的日子里，似乎不可能git all / fetch / commit

错误是：

 错误：没有足够权限将对象添加到存储库数据库.git / objects 
  

使用strace我可以看到这个错误是由于打开时调用：

  [pid 31303] open（.git / objects / b7 / tmp_obj_6wi717，O_RDWR | O_CREAT | O_EXCL，0444）=  - 1 EACCES（权限被拒绝）
 [pid 31303] write（2，error：insufficient permission f...，88error：将对象添加到存储库数据库.git / objects 
  

我无法理解已更改的内容，也不明白为什么git试图在标记为RDRW的444（为所有人阅读）读/写？）。

我在archlinux上使用git 1.8.5.1和samba 4.1.3-1，samba服务器是一个windows（git 1.8.4-1并没有解决问题即使我在使用它的过程中仍然有效）

我已阅读其他SO问题，如 Git over samba - 无法写入sha1文件名|权限被拒绝而没有发现任何关于如何解决问题的提示。

解决方案

你可以看到各种方式来调试在在samba共享上调试git repo权限：

• 为共享设置不同的权限


• 手动安装


• 将samba和git降级到早期版本
  
• sudo - 这个方法可行，但我不想使用它，除非绝对必要


• 在使用sudo后更改所有者和组




Andrew Myers 建议确保您的裸回购包含core.sharedRepository 设置为组。

如果没有，请设置并运行



  cd /path/to/repo.git 
 chgrp -R groupname。 
 chmod -R g + rwX。 
找到。 -type d -exec chmod g + s'{}'+ 
  

不是与内核版本相关的问题：




我已将内核降级到3.11.6，并且在用户再次开始工作时git add / commit。

更新： OP kamaradclimber 报告（或试图）这是一个 内核问题（错误66251） ：






在将内核从3.11.6升级到3.12.1之后，在samba共享上正常工作




由这个补丁。




I have used git trough samba for several times without any issue.

In the last days however, it seems impossible to git all/fetch/commit

The error is :

error: insufficient permission for adding an object to repository database .git/objects

Using strace I can see that error is due to a call on open:

[pid 31303] open(".git/objects/b7/tmp_obj_6wi717", O_RDWR|O_CREAT|O_EXCL, 0444) = -1 EACCES (Permission denied)
[pid 31303] write(2, "error: insufficient permission f"..., 88error: insufficient permission for adding an object to repository database .git/objects

I cannot understand what has changed nor why git is trying to open a file in 444 (read for everybody) with the flag RDRW (read/write ?).

I use git 1.8.5.1 and samba 4.1.3-1 on archlinux, the samba server is a windows (git 1.8.4-1 does not solve the issue even if I used it while it was still working)

I have read other SO questions such as Git over samba - unable to write sha1 filename | Permission denied without finding any hint on how to solve the issue.

解决方案

You can see various way to debug this in "Debugging git repo permissions on samba share":

• setting different permissions for share
• mounting manually
• downgrading samba and git to earlier versions
• sudo - this works but I wouldn't want to use it unless absolutely necessary
• changing owner and group after using sudo

Andrew Myers suggests making sure your bare repo has core.sharedRepository set to group.
If not, set it and run

cd /path/to/repo.git
chgrp -R groupname .
chmod -R g+rwX .
find . -type d -exec chmod g+s '{}' +

If nothing works, make sure it isn't an issue related to the kernel version:

I've downgraded kernel to 3.11.6 and git add/commit as user started working again.

Update: The OP kamaradclimber reports (or tried to) that is was a kernel issue (bug 66251):

Git doesn't work correctly on samba share after upgrading kernel from 3.11.6 to 3.12.1

Fixed by this patch.
