cherry-pick from a branch to another with git-svn automatically stripping git-svn-id from commit message

[Daniele Segato <daniele.bilug@gmail.com>]

Hi,

since git-svn modify the commit message when you dcommit something
(git svn dcommit)
and then use the commit message to decide which is the branch to
dcommit next cherry-pick-ing
(and other commands) has some problem when you work through different
svn branch.

Example, you have 2 remote branch: remote/trunk, remote/v1.x
and you are following them with two branches: trunk and v1.x

now say you want to cherry-pick a commit from trunk into v1.x locally
to dcommit it onto the remote/v1.x branch.

the step you had to do are:
git cherry-pick <your-commit-hash-on-trunk>
git commit --amend # removing the line starting with git-svn-id
# or add the -e option to cherry-pick instead of amending
git svn dcommit


now, if you have to do it frequently it is a bit annoying and you man
do some mistake.

I want to make it automatic and easy to use like:

git cherry-pick-svn <your-commit-hash-on-trunk>
git svn dcommit

with an alias.

on #irc charon suggested me to use !GIT_EDITOR="script that strip the
git-svn-id here" git cherry-pick ...

so I tried this from command line (hash is just a random one):

GIT_EDITOR="sed -i '/^git-svn-id:/d'" git cherry-pick -e 9eb6b7de

it works.

so I opened my ~/.gitconfig and added this alias:

[alias]
	cherry-pick-svn =  !GIT_EDITOR="sed -i '/^git-svn-id:/d'" git cherry-pick -e


but with
$ git cherry-pick-svn 9eb6b7de
I get:
sh: -i: command not found
fatal: Failed to run 'GIT_EDITOR=sed -i -e '/^git-svn-id:/d' git
cherry-pick -e '9eb6b7de...'' when expanding alias 'cherry-pick-svn'


but modifying it with this:
[alias]
	cherry-pick-svn =  !GIT_EDITOR='sed -i /^git-svn-id:/d' git cherry-pick -e

made it working.

I just want to share this with you if someone need it.

And may be ask if you find any problem with this or if you have a
better way to do it

Regards,
Daniele
