Merge development branch with master

Question

I have two branches namely master and development in a GitHub Repository  I am doing all my  development in development branch as shown   git branch development git add   git commit -m  My initial commit message  git push -u origin development   Now I want to merge all the changes on the development branch into the master  My current approach is   git checkout master  git merge development git push -u origin master    Please let me know if the procedure I am following is correct

If you are on Mac or Ubuntu  go to the working folder of the branch  In the terminal   suppose harisdev is the branchname    git checkout master   if there are untracked or uncommitted files you will get an error and you have to commit or delete all the untracked or uncommitted files    git merge harisdev   git push origin master   One last command to delete the branch      git branch -d harisdev

Based on  Sailesh and  DavidCulp    on branch development    git fetch origin master   git merge FETCH HEAD  resolve any merge conflicts if there are any    git checkout master   git merge --no-ff development  there won t be any conflicts now    The first command will make sure you have all upstream commits made to remote master  with Sailesh response that would not happen   The second will perform a merge and create conflicts that you can then resolve   After doing so  you can finally checkout master to switch to master   Then you merge the development branch onto the local master  The no-ff flag will create a commit node in master for the whole merge to be trackable   After that you can commit and push your merge   This procedure will make sure there s a merge commit from development to master that people can see  then if they go look at the development branch they can see the individual commits you ve made to that branch during its development   Optionally  you can amend your merge commit before you push it  if you want to add a summary of what was done in the development branch   EDIT  my original answer suggested a git merge master which didn t do anything  it s better to do git merge FETCH HEAD after fetching the origin master

1  On branch Development  check git status using following command   git status   There should be no uncommitted code  If it is  push your code on Development branch   git add    git commit -m  My initial commit message   git push origin Development   2  On Development branch  run following two commands   git branch -f master HEAD  git push -f origin master   It will push your Development branch code to master branch

Explanation from the bottom for ones who came here without any knowledge of branches   Basic master branch development logic is  You work only on another branches and use master only to merge another branches   You begin to create a new branch in this way   Clone repository in your local dir  or create a new repository      cd  var www   git clone git bitbucket org user name repository name git   Create a new branch  It will contain the latest files of your master branch repository    git branch new branch   Change your current git branch to the new branch    git checkout new branch   Do coding  commits  as usual       git add     git commit -m    Initial commit      git push   pushes commits only to    new branch      When job is finished on this branch  merge with    master    branch     git merge master   git checkout master   goes to master branch   git merge development   merges files in localhost  Master shouldn   t have any  commits ahead  otherwise there will be a need for pull and merging code by hands    git push   pushes all    new branch    commits to both branches -    master    and    new branch     I also recommend using the Sourcetree App to see visual tree of changes and branches

Personally  my approach is similar to yours  with a few more branches and some squashing of commits when they go back to master   One of my co-workers doesn t like having to switch branches so much and stays on the development branch with something similar to the following all executed from the development branch   git fetch origin master  git merge master  git push origin development master   The first line makes sure he has any upstream commits that have been made to master since the last time updated his local repository   The second pulls those changes  if any  from master into development  The third pushes the development branch  now fully merged with master  up to origin master   I may have his basic workflow a little wrong  but that is the main gist of it

Step 1  Create and switch to a new  dev  branch  where your local git files are in-synced with the remote but  dev  branch does not exist yet   git branch dev   create git checkout dev   switch   No need to git add or git commit  the current   branch s files will be cloned to the new branch by-default  git push --set-upstream origin dev   push the  dev  branch to the remote    Step 2  Make your changes to the  dev  branch  your current if you follow step 1   commit and push them to the remote  dev  branch   git add   git commit -S -m  my first commit to the dev branch    remove the -S if you re not  secure   secure   when you already setup crypto private and public keys  i e  verified  green sign in github  git push -u origin dev   push the changes to the remote  -u origin dev is optional but good to use    Step 3  Merge your  dev  branch into the  master    git checkout dev   switch to  dev  branch if you re not already  git merge master   optionally  this command is being used to resolve any conflicts if you pushed any changes to your  master  but  dev  doesn t have that commit  git checkout master   switch to  master   which is the branch you want to be merged  git merge --no-ff dev   merge the  dev  branch into the  master  one

This is how I usually do it  First  sure that you are ready to merge your changes into master    Check if development is up to date with the latest changes from your remote server with a git fetch Once the fetch is completed git checkout master  Ensure the master branch has the latest updates by executing git pull Once the preparations have been completed  you can start the merge with git merge development Push the changes with git push -u origin master and you are done    You can find more into about git merging in the article

I think the easiest solution would be   git checkout master git remote update git merge origin Develop -X theirs git commit -m commit -m  New release  git push --recurse-submodules check --progress  origin  refs heads Master   This also preserves the history of all the branches in use

I generally like to merge master into the development first so that if there are any conflicts  I can resolve in the development branch itself and my master remains clean    on branch development   git merge master  resolve any merge conflicts if there are any  git checkout master git merge development  there won t be any conflicts now    There isn t much of a difference in the two approaches  but I have noticed sometimes that I don t want to merge the branch into master yet  after merging them  or that there is still more work to be done before these can be merged  so I tend to leave master untouched until final stuff   EDIT  From comments  If you want to keep track of who did the merge and when  you can use --no-ff flag while merging to do so  This is generally useful only when merging development into the master  last step   because you might need to merge master into development  first step  multiple times in your workflow  and creating a commit node for these might not be very useful   git merge --no-ff development

Once you  checkout  the development branch you       git add    git commit -m  first commit   git push origin dev  git merge master   git checkout master   git merge dev  git push origin master

Yes  this is correct  but it looks like a very basic workflow  where you re just buffering changes before they re ready for integration  You should look into more advanced workflows that git supports  You might like the topic branch approach  which lets you work on multiple features in parallel  or the graduation approach which extends your current workflow a bit

It would be great if you can use the Git Flow workflow  It can merge develop branch into master easily   What you want to do is just follow the git-flow instruction mentioned here   STEPS    setup the git-flow project  create branches and merge everything to develop run the command git flow release start  lt version number gt  then provide a meaningful message for the release run the command git flow release finish  lt version number gt  it will merge everything into master and change the branch to master  run the command git push to publish the changes to the remote master    For more information  visit the page - http   danielkummer github io git-flow-cheatsheet

If you are using gerrit  the following commands work perfectly   git checkout master git merge --no-ff development   You can save with the default commit message  Make sure  the change id has been generated  You can use the following command to make sure   git commit --amend   Then push with the following command   git push origin HEAD refs for refs heads master   You might encounter an error message like the below      remote rejected  HEAD - gt  refs for refs heads master  you are not allowed to upload merges    To resolve this  the gerrit project admin has to create another reference in gerrit named  refs for refs heads master  or  refs for refs heads     which will cover all  branches in future   Then grant  Push Merge Commit  permission to this reference and  Submit  permission if required to Submit the GCR    Now  try the above push command again  and it should work   Credits   https   github com ReviewAssistant reviewassistant wiki Merging-branches-in-Gerrit  https   stackoverflow com a 21199818 3877642
