Git downloading trunk using subversion bridge

I am using the git to subversion bridge to check out a subversion repository. Initially I was using this command,

get svn clone -s svn://repositoryName/etc

But our subversion repository is massive, many years of develo开发者_如何学Cpment, many branches, etc.

The consequence is that the process dies often, when it is compressing the repository the memory usage goes above 1.5 GB, and it dies.

So I thought perhaps I would try and just check out the trunk because that is what I am going to be using mostly. So I tried this,

get svn clone -trunk svn://repositoryName/etc

But I get an error, Use of uninitialized value in pattern match.

Can someone please tell me the correct command to use for checking out the trunk only. Also is there a known bug / memory leak? I am using Git version 1.7.3.1-preview20201002 on windows.

Is there any official documentation for git and the command line options?

This should work:

git svn clone svn://repositoryName/whatever/trunk

The --trunk option isn't what you're looking for. It's a way to specify the name of the directory that's typically called "trunk". For example, if your svn repository used "/main" for primary development, "/releases" instead of "/tags" and "/other" instead of "/branches", you could use this instead of the -s (--standard) option:

git clone --trunk=main --tags=releases --branches=other svn://repositoryName/whatever

However, a better option may be to clone the repository starting at a particular svn revision number:

git svn clone -r 20000 svn://repositoryName/whatever
cd whatever
git svn rebase

clone -r 20000 will clone only svn revision number 20000. git svn rebase will then fetch and apply all revisions after 20000, so you'll be left with a git repository that has a history beginning at revision 20000.

The man pages are the best place to go for documentation. If you don't have them installed, kernal.org's copy is nicely formatted: http://www.kernel.org/pub/software/scm/git/docs/. A google search for "man git svn" will bring up the relevant page quickly.
