![]() ![]() Getting new branches: At the initial point of a clone you will have all the branches. Our practice is to always do a git fetch and a manual merge rather than just a git pull (which does both of the above in one step). You can then choose to merge this branch into your local copy. Similarly, if you do a git fetch building_groups, the file that is retrieved is placed in your origin/building_groups branch. For example, when you git push a branch called building_groups, your branch goes first to origin/building_groups and then that goes to the remote repository. When you are pushing and pulling the code to/from remote repositories this is actually the mechanism through which that happens. These are the branches that are named origin/branch_name (as opposed to just branch_name). This is mainly because rebasing can alter the history that other people see which may include their own commits. ![]() Only rebase if the branch is local and you haven't pushed it to remote yet! Be aware that rebase, just like merge, can result in conflicts that you have to manually resolve (i.e. So, the process is: save the changes get the 'new' master, and then reapply (this is the rebase part) the changes again against that. It will be 'cleaner' (easier to resolve issues and the history will be easier to understand) if all the changes you have done in a branch are played against the current state of master with all of its latest changes. Since you branched, 'master' itself has since moved forward from that branching point. It doesn't affect the current state and is done to give a 'cleaner' history.īasically, the idea is that you branched from a certain point (usually from master). Branches can also be "rebased" to 'clean up' history. The standard way to bring a branch 'in' to master is to do a merge. ![]() Though this sounds tedious, this is a common approach and is the one that I currently use and recommend because this keeps the master branch cleaner and it's the master that we promote to production, so we only want completed, tested code, via the rebasing and merging of branches. The second is whereby you basically make a branch for every feature request, bug fix or chore and then manually decide when to actually merge those branches into the main master branch. The first is to keep most changes on the master branch, only using branches for larger and longer-running things like version changes where you want to have two branches available for different needs. Other organizations only use branches for major changes such as version upgrades.įork: With a branch you control and manage the branch, whereas with a fork someone else controls accepting the code back in.īroadly speaking, there are two main approaches to doing branches. Many organizations use branches for each piece of work whether it is a feature, bug or chore item. When you've finished, you merge the changes made in the branch back in to the master repository. If the work takes a while or master gets a lot of updates since the branch was made then merging or rebasing (often preferred for better history and easier to resolve conflicts) against the master branch should be done. The only time you need to do manual changes (actually editing a file) is if two changes involve the same line(s) of code.īranches allow you to preserve the main code (the 'master' branch), make a copy (a new branch) and then work within that new branch. It actually does an amazing job of merging file changes (within the same file!) together during pulls or fetches/pushes to a remote repository such as GitHub. ![]() Git doesn't 'lock' files at all and thus avoids the 'exclusive lock' functionality for an edit (older systems like pvcs come to mind), so all files can always be edited, even when off-line. It is also different from SVN in this respect as you could go to any individual version without 'recreating' it through delta changes. Git stores each version of a file that changes by saving the entire file. This is different from systems like SVN where you add and commit to the remote repository immediately. git) which you commit your files to and this is your 'local repository'. This answer includes GitHub as many folks have asked about that too. ![]()
