Thread: https://gitlist.dev/t/23915 ## Matthias Fechner, 2010-05-26 15:13 Subject: Migrate from svn to git Message-ID: <4BFD3AAF.4080403@fechner.net> URL: https://gitlist.dev/e/4BFD3AAF.4080403%40fechner.net ``` Hi, I hope that is the correct list to ask some questions. I understood that the idea behind git is completely different and I like the idea behind git. But for the svn repository I want to convert I need some features and I'm not sure how / if to implement them in git. Corrently the svn repo is divided into trunk branches and tags. In each of this directory like trunk i have directories like hardware, software, docu and more. For each of this subdirectories I have usergroups defined which has no access, read access or rw access. If I understood the manual correctly I can stick on that structure and easily work here with the unix-permission to grant access to the folders? I think I have to test then acl with freebsd to have more then one group for each directory. The second question is, I someone commits some files with svn an email is sent to a svn-commit mailinglist so changes can easily be discussed. The current mail is sent in html format with a colored diff, so it is easier to read. Is something similar possible with git or do you suggest a complete approach? Thanks a lot for answers.

No. Git isn't centralized. Anyone can clone the repo and change anything the want. You implement control by setting a policy on what you merge back into your tree, which is considered canonical. There are several on-commit filtering programs available that can do that automatically based on paths within the repository. > The second question is, I someone commits some files with svn an email is > sent to a svn-commit mailinglist so changes can easily be discussed. > The current mail is sent in html format with a colored diff, so it is easier > to read. > > Is something similar possible with git or do you suggest a complete > approach? There are a lot of these scripts available in contrib and elsewhere. ``` ## hasen j, 2010-05-26 16:26 Subject: Re: Migrate from svn to git Message-ID: URL: https://gitlist.dev/e/AANLkTinTYWQflbvlWVjDKD3gtOyQxDrSZ7QKhy4eI77_%40mail.gmail.com In-Reply-To: <4BFD3AAF.4080403@fechner.net> ``` > Corrently the svn repo is divided into trunk branches and tags. > In each of this directory like trunk i have directories like hardware, > software, docu and more. > > For each of this subdirectories I have usergroups defined which has no > access, read access or rw access. > > If I understood the manual correctly I can stick on that structure and > easily work here with the unix-permission to grant access to the folders? > I think I have to test then acl with freebsd to have more then one group for > each directory.

I've seen it done, e.g. xfce4-commits mailing list. http://foo-projects.org/pipermail/xfce4-commits/ ``` ## Nazri Ramliy, 2010-05-26 17:04 Subject: Re: Migrate from svn to git Message-ID: URL: https://gitlist.dev/e/AANLkTilNlttIQxyhMJz8_wiOQX5OaL0UahsE54mv6rQ3%40mail.gmail.com In-Reply-To: <4BFD3AAF.4080403@fechner.net> ``` On Wed, May 26, 2010 at 11:13 PM, Matthias Fechner wrote: > For each of this subdirectories I have usergroups defined which has no > access, read access or rw access. > > If I understood the manual correctly I can stick on that structure and > easily work here with the unix-permission to grant access to the folders? > I think I have to test then acl with freebsd to have more then one group for > each directory. Dealing with acl sounds like a lot of work and complications to me. Have a look at gitolite. It is covered quite nice in the progit book [1] > The second question is, I someone commits some files with svn an email is > sent to a svn-commit mailinglist so changes can easily be discussed. > The current mail is sent in html format with a colored diff, so it is easier > to read. > > Is something similar possible with git or do you suggest a complete > approach? For this you might want to look at Gerrit [2]. It's a web-based code review. Although it is not email based (AFAIK). nazri.

Is it possible in git to attach script like hooks in svn if someone pull content to the repo?

I would rather receive the raw diff and let my own preferred tools display the information in way that I personally like. Keep in mind that `git diff' is capable of displaying the diff with color.

But it is a way to do it and people are used to do it. I'm thinking more and more about it and I think the best solution is to keep svn as the central repo and do a git svn clone from there, so I have the advantage of the existing infrastructure and will get the nice features from git.

That's probably a good way to get people started with git. However, git hooks SEEM like they should be enough for your purposes. For permissions, see contrib/hooks/update-paranoid: http://git.kernel.org/?p=git/git.git;h=d18b317b2f018d1d1a5a9677a7bdaf8956d65186 and for emails, see see contrib/hooks/post-receive-email: http://git.kernel.org/?p=git/git.git;h=30ae63d74da065a31cced0b161708680f39c04c0 (Sorry if gmail mangles those urls).
