I'm seeing some behavior that my git-fu isn't quite capable of explaining. On a local branch the last commit has a hash different than the remote branch it is tracking from. Nothing has been committed locally and doing: $ git diff branch-name origin/branch-name Comes up empty git pull also says my branch is already up to date. It seems that git pull has generated a bogus commit (a merge commit), but I can't quite figure out why. This is specially important since we need our app servers to have the same commit hash once git pull is done. Anything obvious I'm missing out? Any extra info that can help pinpoint what the issue is? Thank you, Arthur Debert ``` ## John Szakmeister, 2011-04-15 01:46 Subject: Re: Commit hashes differ from local and remote Message-ID: URL: https://gitlist.dev/e/BANLkTi%3DoXF95aE90Wn%3DE%3DyX8P6r79vOOcQ%40mail.gmail.com In-Reply-To: ``` On Wed, Apr 13, 2011 at 3:38 PM, Arthur Debert wrote: > Hi Folks. > > I'm seeing some behavior that my git-fu isn't quite capable of explaining. > > On a local branch the last commit has a hash different than the remote > branch it is tracking from.

I find it useful in understanding issues like this. It does sound like a merge happened, without having any more information to go on. -John ``` ## Alex Riesen, 2011-04-15 15:26 Subject: Re: Commit hashes differ from local and remote Message-ID: URL: https://gitlist.dev/e/BANLkTinEJkLbZRc%2B%3DwMUaBRKq%3DxpxYhk3Q%40mail.gmail.com In-Reply-To: ``` On Wed, Apr 13, 2011 at 21:38, Arthur Debert wrote: > Hi Folks. > > I'm seeing some behavior that my git-fu isn't quite capable of explaining. > > On a local branch the last commit has a hash different than the remote > branch it is tracking from.

In your case both branches just have the same content, for whatever reason. You probably want to specify "--ff-only" (only fast-forwards) to all your pulls to achieve what you seem to want. ``` ## Arthur Debert, 2011-04-15 15:41 Subject: Re: Commit hashes differ from local and remote Message-ID: URL: https://gitlist.dev/e/BANLkTikoaKbxBT%3DE1sXKV6ScLa7eFh8TWw%40mail.gmail.com In-Reply-To: ``` Thanks Alex and John, this makes sense.
