我一直在用Git做我所有的工作,并将其推送到GitHub。我对软件和网站都很满意,我不希望在这一点上改变我的工作实践。
我的博士导师要求所有学生将作业保存在学校托管的SVN存储库中。我发现了大量关于将现有的SVN存储库下拉到Git中的文档和教程,但没有关于将Git存储库推到新的SVN存储库中的文档和教程。我希望通过结合Git -svn、一个新的分支和rebase以及所有这些美妙的术语来实现这一点,但我是Git新手,对其中任何一个都没有信心。
然后,当我选择时,我希望只运行几个命令将提交推到SVN存储库。我希望继续使用Git,让SVN存储库镜像Git中的内容。
我将是唯一一个致力于SVN的人,如果这有什么不同的话。
最近我不得不将几个Git存储库迁移到SVN上,在尝试了我能找到的所有解决方案之后,最后对我有用的是Mercurial(是的,使用了第三种VCS)。根据这份指南,我提出了以下流程(适用于Linux,但基本思路也适用于Windows)。
The necessary packages:
$ sudo apt-get install git subversion mercurial python-subversion
Mercurial needs to be configured by adding the following to ~/.hgrc:
[extensions]
hgext.convert=
Create some temporary working directories (I had several repositories to migrate so I created directories for the SVN and Git versions, to keep them separate):
$ mkdir svn
$ mkdir git
Make an empty local SVN repository:
$ svnadmin create svn/project
Clone the existing Git repository:
$ git clone server/path/project.git git/project
Let Mercurial do its thing:
$ hg convert --dest-type svn git/project svn/project
Now the SVN repository should contain the full commit history, but not with original timestamps. If this is not an issue, skip over the next part to step 11.
With a little work, the date and time of each commit can be changed. Since my repositories are fairly small, it was feasible for me to do it manually. First, create a pre-revprop-change hook in the SVN repository with the following contents, to allow the necessary property to be modified:
#!/bin/bash
exit 0;
This script has to be made executable:
$ chmod +x svn/project/hooks/pre-revprop-change
Mercurial created a working copy of the SVN repository, named project-wc, so switch to it and edit the commit times:
$ cd project-wc
$ svn propedit svn:date --revprop -r 1
Enter the correct date and time (pay attention to timezones!) and save. You should get a message saying "Set new value for property svn:date on revision 1".
Now rinse and repeat for every other revision.
Optionally check the commit history to make sure everything looks OK:
$ svn log -r 1:HEAD
Then go back up one level:
$ cd ..
Dump the repository:
$ svnadmin dump svn/project > project.dump
And load the dump on your Subversion server. Done!
这个过程可能也可以直接在远程存储库之间工作,但是我发现与本地存储库一起工作更容易。修正提交时间需要做很多工作,但总的来说,这个过程比我发现的任何其他方法都要简单得多。
