What every Subversion user must know about Git

Subversion is perfect (simple concept, lots of books, good tool integration, and easy to use) but for the fact that it doesn’t support:

• Merge tracking
• Distributed operation

While the former should be addressed in version 1.5, the latter is anyone’s guess.

The problem is that Subversion is just so good that eventually you will will want a distributed mode with Subversion.

Fortunately, Git supports distributed operation against Subversion repositories!

If this gets you “on the Git bus”, check out this:

Addendum 05/03/08:

Tonight I tested out setting up cygwin from scratch to use Git, and in doing so confirmed what I knew and discovered what I didn’t!

You must use the following packages:

1. Git 1.5.5.1-1
2. Subversion 1.4.5-2
3. Subversion-perl 1.4.5-2

Failure to install the subversion-perl bindings results in the error: = Can’t locate SVN/Core.pm in @INC

Thank you ycdtosa for the pointer!

Addendum 05/03/08:

If, like many of us, you haven’t fully cut over to cygwin, you may receive the following error message when you attempt a commit:

You have some suspicious patch lines=

Here is both an explanation of and a work-around for the error.

To solve the problem, you need to edit .git/hooks/pre-commit and comment out the following lines:

=if ($) { bad_line(“trailing whitespace”, $_); }=

Before tonight, I figured that I would never have the need to use dos2unix ever again! Based on one of the commentors replies, though, I expect that further research on the operation of Git is required on my part in order work between CR and CRLF environments:

Git from some time has core.autocrlf and crlf attribute, which should help in mixed UNIX (LF) and Windows (CR LF) environment
