Only when I try to *pull* does it give me a hint: [dwmw2@shinybook mtd-2.6]$ git pull You are not currently on a branch, so I cannot use any 'branch..merge' in your configuration file. Please specify which branch you want to merge with on the command line and try again (e.g. 'git pull '). See git-pull(1) for details. So I've been happily thinking that my commits were actually in linux-next for the last couple of weeks when they weren't. OK, I could have checked in gitweb — silly me for trusting the tools. Why would it do this evil thing and start lying to me? When it told me 'Everything up-to-date', precisely *what* was it telling me was up to date? Did it ever push *anything*, *anywhere*, or was it just a complete fabrication? I don't quite know how I ended up "not currently on a branch" either. I almost never use branches locally and my local tree has *never* been changed to another branch; I always use separate trees instead of branches. I may have committed a few things, then reverted them with 'git reset HEAD^^^^' and re-committed them with some changes. But that shouldn't cause this, surely? When I have a clone a remote tree, and I run 'git push', surely my HEAD should be pushed to the HEAD of the remote tree? There's little excuse for *telling* me it's up-to-date, when it's not! I understand that some people like the branch facility even though I find it mostly pointless, but I'd prefer that it didn't undermine basic usability of git :( -- dwmw2 ``` ## Matthieu Moy, 2012-05-28 12:11 Subject: Re: "git push" silently fails, says 'Everything up-to-date" when it's not.

You probably have push.default=matching, which is the default. In this mode, Git will push all your local branches to remote branches having the same name (regardless of which branch you currently have checked-out). The commits you just did were not on any branch, so they're not pushed. > Why would it do this evil thing and start lying to me?

It probably pushed your branches, but not commits done in detached HEAD. > I don't quite know how I ended up "not currently on a branch" either. Either you did "git checkout " (in which case you had a big fat warning), or you used one command that runs in detached HEAD like "git rebase" or "git bisect" without concluding the operation ("git bisect reset", "git rebase --continue" or so). With a recent enough version of Git, each commit you did in detached head had this little reminder: $ git commit -m foo [detached HEAD acb1d5b] foo ^^^^^^^^^^^^^ As for the future, there's a patch serie in progress that will make "git status" warn a bit more loudly in these cases, and give you a clue about what to do next. In Git 2.0, the push.default value will change to "simple", which errors out like this in your case: $ git push fatal: You are not currently on a branch. To push the history leading to the current (detached HEAD) state now, use git push origin HEAD: If you can't wait to have this "simple" mode, you may want to set push.default=upstream (or current), which will push the current branch to its upstream (or to the one with the same name remotely). I don't know what can be done to improve the case of detached HEAD with push.default=matching. Perhaps Git should warn when HEAD is not pushed (detached HEAD, or HEAD points to a branch that doesn't exist remotely)? -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ``` ## Junio C Hamano, 2012-05-29 18:53 Subject: Re: "git push" silently fails, says 'Everything up-to-date" when it's not.

For those whose workflow clearly separates local history building (checking different branches, making commits, etc.) and publishing the result (git push), "git push" is *not* a way to say "I am done with the work I have been doing on *this* branch", but is a way to say "I am done for the day, and all the branches I push out are in good order". It does not matter what branch the user happens to be on when "git push" is run for them (including me). ```
