<godiard> quozl: aha
:'''<Quozl>''' the problem with doing "git merge quozl/master" at this point is that all of my mistakes in history are simply copied into mainline.
<Quozl> copying my bad history into mainline makes mainline history harder to read.
:'''<bernie>''' Quozl: exactly!
>walterbender< are you enjoying the git class too? :-)
:'''<godiard>''' quozl: aha
<bernie> godiard: the rebase would take the old history that looked like this:

<Quozl> godiard: the history of change to code is almost as valuable as the code itself, sometimes.
A---B---C topic
<bernie> godiard: and change it to a new history that looks like this:
/
D---E---F---G master
:'''<Quozl>''' godiard: the history of change to code is almost as valuable as the code itself, sometimes.
<Quozl> (quozl.git is topic?)
:'''<bernie>''' godiard: and change it to a new history that looks like this:
<bernie> godiard: take your time to see what is happening :)
<bernie> Quozl: yep
A´--B´--C´ topic
<godiard> bernie: ok
/
<bernie> Quozl: and yep, the history is important... maybe not in a small activity, but it's very important in a project the size of sugar
D---E---F---G master
<godiard> bernie: i will to print this and read many times :)
<Quozl> godiard: you must go to dinner now?
:'''<Quozl>''' (quozl.git is topic?)
<bernie> godiard: ok, git can do this almost automatically. sometimes it will need your help because A, B, C changed the same lines of E, F, G...
:'''<bernie>''' godiard: take your time to see what is happening :)
<bernie> godiard: I can suggest some cool git tutorials and docs
:'''<bernie>''' Quozl: yep
<godiard> bernie: this time is easy, mainline didn change
:'''<godiard>''' bernie: ok
<bernie> godiard: anyway, after all the theory, all you need to do is: git rebase quozl/master
:'''<bernie>''' Quozl: and yep, the history is important... maybe not in a small activity, but it's very important in a project the size of sugar
<bernie> godiard: WHAM! you have rebased
:'''<godiard>''' bernie: i will to print this and read many times :)
<godiard> bernie: yes, i need read more

:'''<bernie>''' godiard: ok, git can do this almost automatically. sometimes it will need your help because A, B, C changed the same lines of E, F, G...
<bernie> godiard: you could, but you would make a small mistake. I did it... so you can do it too and I'll show you how to remedy
:'''<bernie>''' godiard: I can suggest some cool git tutorials and docs
<godiard> First, rewinding head to replay your work on top of it...
:'''<godiard>''' bernie: this time is easy, mainline didn change
<godiard> Fast-forwarded master to quozl/master.
:'''<bernie>''' godiard: anyway, after all the theory, all you need to do is: git rebase quozl/master
<Quozl> works for me too, but it looks the same in gitk. what is the difference?
:'''<bernie>''' godiard: WHAM! you have rebased
<bernie> godiard: ok, now look at the history... you have all the changes that quozl had done!
:'''<godiard>''' bernie: yes, i need read more
<godiard> yes

<godiard> then i must do push?

<godiard> i can do it in the local repo?

<bernie> godiard: yes, first we need to undo the rebase

<godiard> bernie and quozl: sorry can we continue in 1 hour?
