Git

For hosting see Gitolite and Gitlab.

Bisect

Simple, auto:

git bisect start BAD_COMMIT GOOD_COMMIT
git bisect run test_runner tests/

Reset Local Master Branch to State of Remote Master

git checkout master
git branch failmaster
git reset --hard origin/master

Explanation:

go to master branch
(optional) save it as „failmaster“ and go there (we need to go somewhere else than master for the next step)
reset to origin/master, ignoring all local changes

Push all branches from one remote to another

To push all branches present in the remote origin to the new remote serv:

source=origin
destination=serv
git push $destination +refs/remotes/$source/*:refs/heads/*

Log with Author Date

By default git shows the „commit“ date. When rebasing a branch all commit dates are a few seconds old even if they were authored months ago. Here are my short log entries - one with relative dates and another with ISO dates, e.g. 2014-06-04 15:11:47.
