Update local MESSy-CLaMS repository

Get changes from remote repository

• Fetch and merge changes on the remote server to your working directory:

  git pull

See changes before pulling from remote git repository

• Fetch changes from the remote repository:

  git fetch

  Show commit logs of changes / show diffs of changes:

  git log --name-status devel..origin/devel
  git diff --name-status devel origin/devel
  git diff devel origin/devel

  Apply the changes by merge or just pull the changes:

  git merge 
  or
  git pull

Merging with local modification

• If you pull from the remote repository and there are local uncommitted modifications in files that have also been changed in the remote repository, you will fail and get a message like this: "Please, commit your changes or stash them before you can merge."
  
  

  Then you have three options:
  
  

  1. Commit changes

     git add ...
     git commit ...
     git pull

  2. Stash changes
     
     Stashing acts as a stack, where you can push changes, and you pop them in reverse order. Stash, do the merge and then pull the stash:

     git stash
     git pull
     git stash pop

  3. Discard changes
     
     Discard all local changes to all files and get current version from remote repository:

     git reset --hard origin/devel
     git pull

     Discard local changes for a specific file:

     git checkout -- filename
