![]() ![]() What is the ref/heads/master? Just another file, this time one thatĬontains an actual SHA: $ cat. # This ref has changed to reflect the branch name. Watch what happens when I change to the master branch (I was on the # FYI: refactor_types was the name of the branch I was on at this time. Then looking inside on of these ALL CAPS files: $ cat HEAD There is useful information available by inspecting the ALL_CAPS filenames in the. ![]() This usually means it's time for you to push. This means you have commits locally that are ahead of (your computer's) view of ![]() The general case for 'your branch is ahead of origin/master' Origin/master by X commits" and this persisted rather stubbornly. Now, the other people's git instances had issues like "your branch is ahead of Moving HEAD back to before this change then force pushing this to GitHub. Person's recent changes, then pushed this out. This also enables a new git 1.9/2.0 feature for finding upstream rebases.At work, someone resolved a merge conflict in a way that clobbered another If you want the old remote-branch SHA-1, it defaults to being saved in, and thus recoverable from, the reflog. (It was, as the release notes say, a deliberate design decision to skip the update, but it turns out that more people prefer that git update it. If you use the more-explicit git fetch origin (then optionally look around) and then git merge origin/master sequence, you can also bring your own local master up to date with the remote, with only one fetch run across the network: git fetch originġThis second part has been changed-I say "fixed"-in git 1.8.4, which now updates "remote branch" references opportunistically. (In particular the fetch step run by pull brings over only origin/master, and it does not update the ref in your repo: 1 any new commits winds up referred-to only by the special FETCH_HEAD reference.) So this is almost the same as doing the two steps by hand, but there are some subtle differences that probably are not too concerning to you. The pull command instructs git to run git fetch, and then the moral equivalent of git merge origin/master. When you use the sequence: git checkout dmgr2 You can insert -no-ff or -ff-only to prevent a fast-forward, or merge only if the result is a fast-forward, if you like. Sometimes this is only useful for Warm Fuzzy Feelings ("ah, yes, that is in fact what I want") and sometimes it is useful for changing strategies entirely ("whoa, I don't want THAT stuff yet").įinally, the merge command takes the given commit, which you can name as origin/master, and does whatever it takes to bring in that commit and its ancestors, to whatever branch you are on when you run the merge. They get copied to your repository, but named origin/branch for any branch named branch on the remote.Īt this point you can use any viewer ( git log, gitk, etc) to see "what they have" that you don't, and vice versa. The fetch command can be done at any point before the merge, i.e., you can swap the order of the fetch and the checkout, because fetch just goes over to the named remote ( origin) and says to it: "gimme everything you have that I don't", i.e., all commits on all branches. Git fetch origin # gets you up to date with origin The steps you listed will work, but there's a longer way that gives you more options: git checkout dmgr2 # gets you "on branch dmgr2" ![]()
