Confusion using git on svn server

Hi

I just began using git on a svn file, which seems really nice. I'm for now confused with a git operation, as maybe my mind is still thinking with svn vision.

As I understood, unlike svn, you can make many commit without sending them to the server, and then then sending them in one block with git-svn dcommit (if I'm right, with push if git server).

So two questions: -Where can I find documentation on that? Didn't find mention on it in git user manual or git-svn crash course.

-say I want to know, before doing git-svn dcommit, which commits will be sent, and if this will do a conflict... is there a way to check that before sending the commits?

My main concern is that in my git log, I have a commit and its "revert", will it be sent as two different commits to svn? I would love they are not sent at all as they represent a "neutral" operation.

Thanks a lot!
