Git trick

Piku — Fri, 13 Jun 2008 21:11:23 +0000

A friend asked me about an error he had while trying ‘git pull, it was saying that file X was not uptodate.

For git pull (actually for merge) you need to not have anything uncommited (either commit or reset). But he did not wanted to commit because he didn’t finished working neither reset because he would lose his work.

There is another way, git stash: Git stash saves your modifications away and gives you a clean working dir. Use ‘git stash ‘ to create a stash. With ‘git stash list‘ you can view your stashes, ‘git stash show ‘ to view a specific stash and ‘git stash apply ‘ to apply it.

In his case he needed to run:

git stash work
git pull
git apply work

Long time gone

I haven’t written for a long time here. I was very busy with school and the InfoMatrix competition, where I won Silver medal with my ruby continuous integration service, more about it in a short while.

I am working more and more with Ruby, Rails professionally and trying out Merb, Datamapper, Amazon Web Services for personal project. I will try and post here from time to time my experiences with Ruby and other things I am using.

If you have anything that you would like me to write about please say. Also if you want to test my continuous integration (it’s kind of alpha) then please contact me.

Compiling git with documentation

Piku — Sat, 03 May 2008 13:34:33 +0000

I have previously posted how to compile git on Ubuntu but while using git I wanted to consulte the manual to get information about some commands and git help didn’t work. It seems that you have to manually specify when compiling that you want to have documentation included too.

Here’s how to do that. Go to the directory where you have unarchived git sources and type:

make doc
sudo make install-doc

You can also combine them when you compile git:

make all doc
sudo make install install-doc

Braid 0.4

Piku — Thu, 01 May 2008 12:10:24 +0000

Braid 0.4 has been released, Braid is a simple tool to help track git and svn vendor branches in a git repository. I had a previous coverage of Braid 0.3.

The new features include squashed mode, in which you have only one commit when adding a mirror instead of having all the history and a team mode. It also requires Git version 1.5.4.5 or higher (see my post on updating git). If you hit any bug please report them.

The wiki has usage and examples. You can install it with rubygems (don’t forget to upgrade to RubyGems 1.1.1):

gem sources -a http://gems.github.com/
gem install evilchelu-braid

Or you can get it from the Git repository.

If you used my previous Braid tutorial here’s how to upgrade Rspec to the git repository and get the latest version. If you do not have rspec svn setup you can skip this part.

braid remove vendor/plugins/rspec
braid remove vendor/plugins/rspec_on_rails
git merge braid/track

I think I hit a bug and had to delete the folders manually:

 rm -rf vendor/plugins/rspec vendor/plugins/rspec_on_rails

Now to install the git repositories:

braid add -p -t git git://github.com/dchelimsky/rspec.git
braid add -p -t git git://github.com/dchelimsky/rspec-rails.git
git merge braid/track

Updating git on ubuntu

Piku — Mon, 14 Apr 2008 18:53:27 +0000

Updated with the latest git release 1.5.5.1

I am using Ubuntu 7.10 Gutsy and use git a lot, the latest version in gutsy repository is 1.5.2.5 but the latest version of Git is 1.5.5.1 so here’s a quick tip for compiling git.

First remove git if you have installed it from repositories:
sudo apt-get remove git git-svn

Then go into a temporary folder where you will download and compile git:
wget http://kernel.org/pub/software/scm/git/git-1.5.5.1.tar.bz2 sudo apt-get build-dep git-core tar xjf git-1.5.5.1.tar.bz2 cd git-1.5.5.1/ ./configure make sudo make install
If you have a dual core CPU and want to use them both to compile faster use make -j2 instead of make

Now enjoy your hand compiled git

PS: For git gui I had to to install tk (sudo apt-get install tk).
