Git set up a public repository

April 29, 2009 / mattions / 1 Comment

If you have to set up a public repository with git you can follow the instruction found on the git-core tutorial
(Hint: Search for “Publishing your work”)

Things to keep in mind:

Public repository are usually named as project.git and it’s a directory even if you can be mislead to think it’s a file for the extension (.git). Well, it’s not a file.
you need to login in the remote host (the one from which you will share your repo) and initialized a local git database:
- ssh account compulsory
- git should be in the path and available in the web server
You need an ssh account over there.
Then you can push your changes to the new shiny repo.

The steps to do that:

login the remote <public-host>
mkdir project.git
```
GIT_DIR=my-git.git git init
```
mv project.git/hooks/post-update.sample project.git/hooks/post-update This make sure that after every push the git update-server-info is ran and your repo can be accessed in the public way.

git push <public-host>:/path/to/project.git master

Git Again – Svn Workflow

April 15, 2009 / mattions / 0 Comments

On this page on the GNOME website I found how to use git properly if you are using it as a gateway to a svn:

git svn clone _svn_server_location #Clone the repository
git svn fetch #Download the stuff
git svn rebase #Merge the updates with the current
git checkout -b myfeature #Create a local branch
hack hack hack # hack
git commit -am "changed stuff" # Commit
hack hack hack # hack
git commit -am "changed other stuff" # Commit
git checkout master # Change to master branch
git merge --squash myfeauture #Merge myfeature to master
git commit -am "merge the feature to the master"
git svn dcommit # Commit everything on the svn server

Some stuff about git you should know

April 10, 2009 / mattions / 3 Comments

Git rocks, and after two days of using I can confirm it.

I was a user of bazar, but with the switching of GNOME to git and the big trouble that bazar was giving me to commit on the svn of the EBI I decided to give to git a go.

Also on bioinfoblog the match between git and bazar it’s a though one, but I right now the svn support from git just works out of the box, so I started to use it.

I want also to point out that with the last git (ATMOW) is possible to create a remote branch on the svn server with:

git svn branch mybranch

and this was one of the killer feature that made me switch.

This is not a tutorial on git but I will provide you some quick and dirty pointers to other posts that I found interesting for a quick introduction to git.

Stuff to keep in mind about git:

You always work in a local branch.
You commit locally
You push (or dcommit if using a remote svn repository) to the remote branch.
The name of a remote branch is remote/foobar and you need to put the remote prefix also if it doesn’t show up with the remote prefix not optional. You need this if you create a local branch and you want to track a remote branch.

Some pointers here:

I’ve customized my bash prompt to show my current branch on a git repository. This is the code (based on some code found on the net that I can’t track anymore.. I’m sorry….) looks like this:
#git branch parse_git_branch() { git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* (.*)/(1)/' } #grey PS1='[33[0;32m]u[33[1;32m]@[33[0;32m]h[33[00m]:[33[01;34m]W[33[1;30m]$(parse_git_branch)[33[00m]$ '

The terminal looks like this

GMail offline available

March 21, 2009 / mattions / 4 Comments

It was a long time that I was wondering when the offline service will be available….

Gears is out for a while, so the technology was there….

Today I discovered gmail offline becomes available from the lab.

Well, it’s the same idea of the readers offline… It’s really good stuff. Give it a go. You need gears and lab installed 😛

Ubuntu: Black screen at the login

March 5, 2009 / mattions / 6 Comments

Today I’ve got a black (sad) screen after restarting the computer. The boot process was fine but everything seems to hang when the nvidia drivers was supposed to kick in and Xorg start.

It was impossible to fall back to any console text login type.

I’ve searched the internet here and there, but I was not able to find any solution or bug report, so I come up with an workaround.

I think the problem is due to the new kernel that I’ve installed following one of the suggested update and the incompatibility with the nvidia drivers. I don’t know if it is the true problem, but I have an hint that this can be true.

As the matter of fact I’ve changed the kernel at the boot time� (Push Esc when GRUB is showing the timeout for the default choice) and I choose the previous version (i.e. Ubuntu 8.10, kernel 2.6.27-12-generic).

With this one I was able to login and my system seems to be completely functional, up and running again.

For the time being I decided to stick with this kernel.� I edited the grub menu list (/boot/grub/menu.lst) changing the default 0 (Ubuntu 8.10, kernel 2.6.27-13-generic) with the second option (Ubuntu 8.10, kernel 2.6.27-12-generic).

Here my current menu.lst

# menu.lst - See: grub(8), info grub, update-grub(8) # grub-install(8), grub-floppy(8), # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-doc/.


## default num

# Set the default entry to the entry number NUM. Numbering starts from 0, and

# the entry number 0 is the default if the command is not used.

#

# You can specify 'saved' instead of a number. In this case, the default entry

# is the entry saved with the command 'savedefault'.

# WARNING: If you are using dmraid do not use 'savedefault' or your

# array will desync and will not let you boot your system.

default		2
## timeout sec

# Set a timeout, in SEC seconds, before automatically booting the default entry

# (normally the first entry defined).

timeout		3

# Hides the menu by default (press ESC to see the menu)
