git解压缩错误推送到gerrit

Question

在将新分支推送到gerrit服务器时,我们遇到以下错误:

de@roma:~/git-hate/www$ git push origin landingpage
Counting objects: 149, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (73/73), done.
Writing objects: 100% (111/111), 2.77 MiB, done.

fatal: Unpack error, check server log
To ssh://user@git-server/repository
 ! [remote rejected] landingpage -> landingpage (n/a (unpacker error))
error: failed to push some refs to 'ssh://user@git-server/repository'

我们尝试将提到的树对象手动复制到远程git,但没有成功.

在gerrit方面,我们得到一个堆栈跟踪:

伙计们:任何想法该怎么办？

Answer 1

与推进--no-thin论证工作对我来说是解决方法:

git push --no-thin omnigerrit HEAD:refs/for/android-4.4

Answer 2

你使用的是git> 1.8.4.2吗？

我发现git 1.8.4.3+和gerrit 2.6之间不兼容,因为 https://github.com/git/git/commit/fbd4a7036dfa71ec89e7c441cef1ac9aaa59a315

通过此增强功能,如果git发现树sha1已经存在于服务器中,它将不再发送它,但是gerrit想要搜索与上传包中的提交sha1相关联的树sha1.

看起来我无法使用gerrit 2.8-rc3重现它,而不是最新版本的scm-manager.我会说这已经在jgit中解决了,但还找不到哪个版本.

Answer 3

我的情况

我也遇到了这个问题,这需要很长时间来解决这个问题.

首先,我注意到gerrit日志中的一个错误信息:

Internal server error (user newptone account 1) during git-receive-pack                           '/neutron.git' 
com.google.gerrit.sshd.BaseCommand$Failure: fatal: Unpack error,   check server log
......
... Missing unknown 613fd2557fba30aff2dbd51c3807cc57561bab08

什么是613fd2557fba30aff2dbd51c3807cc57561bab08对象？

然后我用git review -l来搜索这个项目neutron的所有打开的补丁集:

1974  master  Add two interfaces for manipulate forwarding individually

然后我通过搜索在gerrit仪表板中找到这个补丁集,我点击链接,似乎错误:

613fd2557fba30aff2dbd51c3807cc57561bab08 cannot  found

啊哈,这就是原因!

但为什么这个对象丢失了？

原因是我的同事告诉我中子项目将使用新的repo来替换旧的,我删除旧的repo但没有关闭所有打开的补丁集中的gerrit.打开的补丁集将在gerrit仪表板中消失,但它仍然存在于gerrit数据库中.

如何解决它

登录您的reviewdb sql并找到此记录:

首先,确保这是我们要修改的那个:

select * from changes where change_id=1974\G;

然后更新此记录:

update changes set open='N',status='A' where change_id=1974;

Answer 4

我刚刚遇到这个错误.

对于我的场景,我试图推送修改后的提交,其中自上次推送相同提交以来没有任何文件发生过更改.我确实修改了改变的提交消息,并试图再次推送.作为提交的一部分的文件没有更改.

我的推送被拒绝,并发布了相同的错误消息.

似乎Gerrit不喜欢推送除了修改后的提交消息之外没有任何更改.

我确实对文件进行了一个字符更改,添加了文件,再次修改了提交,然后推送,并且推送成功.

我正在使用git == 1.8.4.2

Answer 5

我今天遇到了这个问题并尝试了所有的建议.最后解决方案非常简单:

1. 切换到另一个分支(例如开发).
2. 从远程存储库中提取
3. 切换回新分支并推送.

运气好的话现在就可以了.
