Thread: https://gitlist.dev/t/11156 ## Harvey Harrison, 2007-12-06 06:22 Subject: [RFC] Mirroring svn Message-ID: <1196922153.10408.101.camel@brick> URL: https://gitlist.dev/e/1196922153.10408.101.camel%40brick ``` After the discussions lately regarding the gcc svn mirror. I'm coming up with a recipe to set up your own git-svn mirror. Suggestions on the following. // Create directory and initialize git mkdir gcc cd gcc git init // add the remote site that currently mirrors gcc // I have chosen the name gcc.gnu.org *1* as my local name to refer to // this choose something else if you like git remote add gcc.gnu.org git://git.infradead.org/gcc.git // fetching someone else's remote branches is not a standard thing to do // so we'll need to edit our .git/config file // you should have a section that looks like: [remote "gcc.gnu.org"] url = git://git.infradead.org/gcc.git fetch = +refs/heads/*:refs/remotes/gcc.gnu.org/* // infradead's mirror puts the gcc svn branches in its own namespace // refs/remotes/gcc.gnu.org/* // change our fetch line accordingly [remote "gcc.gnu.org"] url = git://git.infradead.org/gcc.git fetch = +refs/remotes/gcc.gnu.org/*:refs/remotes/gcc.gnu.org/* // fetch the remote data from the mirror site git remote update // set up git-svn // gcc has the standard trunk/branches/tags naming so use -s // add a prefix so git-svn uses the metadata we just got from the // mirror so we don't have to get everything from the svn server // the --prefix must match whatever you chose in *1*, the trailing // slash is important. git svn init -s --prefix=gcc.gnu.org/ svn://gcc.gnu.org/svn/gcc // your config should look like this now: [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true [remote "gccmirror"] url = git://git.infradead.org/gcc.git fetch = +refs/heads/*:refs/remotes/gccmirror/* [svn-remote "svn"] url = svn://gcc.gnu.org/svn/gcc fetch = trunk:refs/remotes/gcc.gnu.org/trunk branches = branches/*:refs/remotes/gcc.gnu.org/* tags = tags/*:refs/remotes/gcc.gnu.org/tags/* // Try and get more revisions from the svn server // this may take a little while the first time as git-svn builds // metadata to allow bi-directional operation git svn fetch Happy Hacking Harvey Harrison ``` ## Jeff King, 2007-12-06 06:43 Subject: Re: [RFC] Mirroring svn Message-ID: <20071206064317.GC18698@coredump.intra.peff.net> URL: https://gitlist.dev/e/20071206064317.GC18698%40coredump.intra.peff.net In-Reply-To: <1196922153.10408.101.camel@brick> ``` On Wed, Dec 05, 2007 at 10:22:33PM -0800, Harvey Harrison wrote: > // fetching someone else's remote branches is not a standard thing to do > // so we'll need to edit our .git/config file > // you should have a section that looks like: > [remote "gcc.gnu.org"] > url = git://git.infradead.org/gcc.git > fetch = +refs/heads/*:refs/remotes/gcc.gnu.org/* > // infradead's mirror puts the gcc svn branches in its own namespace > // refs/remotes/gcc.gnu.org/* > // change our fetch line accordingly > [remote "gcc.gnu.org"] > url = git://git.infradead.org/gcc.git > fetch = +refs/remotes/gcc.gnu.org/*:refs/remotes/gcc.gnu.org/* FWIW, if you are writing a shell recipe for other people to cut and paste, you can say this as: git config remote.gcc.gnu.org.fetch \ '+refs/remotes/gcc.gnu.org/*:refs/remotes/gcc.gnu.org/*' -Peff ``` ## Harvey Harrison, 2007-12-06 06:45 Subject: Re: [RFC] Mirroring svn Message-ID: <1196923525.10408.103.camel@brick> URL: https://gitlist.dev/e/1196923525.10408.103.camel%40brick In-Reply-To: <20071206064317.GC18698@coredump.intra.peff.net> ``` On Thu, 2007-12-06 at 01:43 -0500, Jeff King wrote: > On Wed, Dec 05, 2007 at 10:22:33PM -0800, Harvey Harrison wrote: > > > // fetching someone else's remote branches is not a standard thing to do > > // so we'll need to edit our .git/config file > > // you should have a section that looks like: > > [remote "gcc.gnu.org"] > > url = git://git.infradead.org/gcc.git > > fetch = +refs/heads/*:refs/remotes/gcc.gnu.org/* > > // infradead's mirror puts the gcc svn branches in its own namespace > > // refs/remotes/gcc.gnu.org/* > > // change our fetch line accordingly > > [remote "gcc.gnu.org"] > > url = git://git.infradead.org/gcc.git > > fetch = +refs/remotes/gcc.gnu.org/*:refs/remotes/gcc.gnu.org/* > > FWIW, if you are writing a shell recipe for other people to cut and > paste, you can say this as: > > git config remote.gcc.gnu.org.fetch \ > '+refs/remotes/gcc.gnu.org/*:refs/remotes/gcc.gnu.org/*' I thought about that, but I like to encourage people to actually look at the config file, it's pretty easy to understand.

I agree that people should be encouraged to edit their .git/config. But a recipe is something easy-to-follow IMHO, so I would write this as a shell script (with #-comments, not //-comments).

I'll probably turn it into such eventually, this was more of a hand-holding exercise for people who would like to try git in gcc-land. Harvey ```
