How to see what has been checked into git, but hasn't been committed to svn via dcommit?

I'm using git-svn. How can I get a list of what I've committed into git, but haven't yet committed to the SVN repository since the last git svn dcommit? That is, how can I verify what is about to be sent if I do a dcommit?

Solution

The --dry-run option for git svn dcommit is very useful for finding out exactly what will be committed to Subversion. In particular that has the properties that:

It doesn't actually commit anything to Subversion
It tells you which diffs will be calculated to create new revisions in Subversion
It tells you which branch in Subversion you will be committing to - this is sometimes non-obvious, since it is taken from the Subversion branch specified in the first ancestor commit with a git-svn-id in its commit message

In general it's a good idea to do git svn rebase before even thinking about using dcommit, so that your history is linearized - otherwise merge commits may not make much sense in the Subversion history. (If you've done that, then git log and gitk --all will also be essentially equivalent, but I think git svn dcommit --dry-run gives you a more accurate picture of what's about to happen, even if it's more difficult to interpret.)
