Git is an extremely powerful and flexible revision control system, and using it effectively requires adherence to conventions.

IIS Repository Policy

Please adhere to basic guidelines for Editing and Committing.

Basic Workflow

git std. usage

Retrieve an IIS Git tree for you to work on:

git clone

PROJECTNAME will typically include a path portion.

Prepend the hostname with USERNAME@ if your Git username does not match your local username.

Now make your edits. To see the status of your files with respect to your repository, do:

git status

For each reasonable unit of changes, tell Git that you want to keep it, and then commit it to your local tree:

git add FILENAME
git commit -m "brief documentation of your changes"

Each self-contained, fully-functional set of changes that you want to make public should be pushed upstream to the IIS master tree:

git push

At this point you are free to delete your local Git tree.

In the meantime, you can retrieve updates from the IIS master tree with:

git pull

For more information, see the Git Reference and Everyday Git.

A git pull will automatically merge any edits other people have pushed in the meantime. However, this will fail if such edits happened in the same section of a file as the changes you are trying to push. In this case, git pull will signal a merge conflict, which needs to be resolved by hand.

Here you may find a nice tutorial on how you can do merging by using vimdiff (you should be able to use vim for using it).

Understanding Git

Here is an excellent and brief explanation of Git's internal representation and how it supports user-level interactions. Very useful to understand Git.

Two key distinctions from Subversion (SVN) are

Git Revisions

The following diagram is an example 'commit' view of a master tree (w.o. branches). it describes the difference between revert and reset.

git revisions wo branches

Textmode Tool For Git

a nice (commandline) tool for viewing commits, logs, diffs and other changes is tig. to install tig on a debian based machine

apt install tig

change into the git working directory and start



Generate Patches and use Peer-to-peer patch exchanges 1)

git format-patch --cover-letter -o some-dir d8a285c8f83f728be2d056e6d4b0909972789d51..9202ec15da36ca060722c363575e0e390d85fb71
# this is equivalent to, this is the short form
git format-patch --cover-letter -n -o some-dir d8a28..9202e

Where d8a28 was the last commit before you started hacking and 9202e is the current head, meaning the commit ID of your latest commit.

For renaming files add “-M” to the git-format-patch arguments then patches wont create removals and adds for a simple rename.

Sending Patches:

git send-email --no-chain-reply-to --from "My Name <>" --to recipient@domain some-directory/

ssh Config

You could also create an ssh config file in your home-directory to shorten the git commands: The ~/.ssh/config file could look like:

Host iis
    Port 22
    User username
    #IdentityFile  ~/.ssh/PRIVATEKEYFILE 

The IdentityFile line is only for ssh key auth necessary.

The commands then would look like

git clone ssh://iis/projects/git/projectname
