Unable to find filename with git blame error

[dcaunt]

I'm seeing the error Unable to find filename with git blame when trying to Open either a commit or file on GitHub. I tried for a couple of projects, one on a corporate GitHub and one on github.com.

In the system console, I can see logs showing my GIT remotes (shows remotes correctly) and GIT blame (blank). Xcode's blame and comparison source control features are working fine.

Can you post a redacted version of your remotes and the output of git status?
Thanks!

Below is my setup for Mantle, as this is public:

$ git remote -v
origin https://github.com/MantleFramework/Mantle.git (fetch)
origin https://github.com/MantleFramework/Mantle.git (push)

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean

Console output from Xcode:

15/04/2014 14:34:32.348 Xcode[4464]: GIT remotes: (
"origin\thttps://github.com/MantleFramework/Mantle.git (fetch)",
"origin\thttps://github.com/MantleFramework/Mantle.git (push)",
""
)
15/04/2014 14:34:32.450 Xcode[4464]: GIT blame:

I wasn't able to reproduce the error.

Can you go to your Mantle directory and run the following on the command?

git --no-pager blame -L11,11 -l -s -n -f -p /[YOUR-PATH]/Mantle/Mantle/Mantle.h

What is the output? Is your Git located at /usr/bin/git? What is your Git/Xcode/OSX version?

Thanks!

My git is a symlink to Homebrew's git:

/usr/local/bin/git -> ../Cellar/git/1.9.1/bin/git

Git version is 1.9.1:

$ git --version
git version 1.9.1

Xcode Version 5.1.1 (5B1008).
OS X Mavericks 10.9.2 Build 13C64

blame output:

$ git --no-pager blame -L11,11 -l -s -n -f -p ~/Projects/Mantle/Mantle/Mantle.h

I tried a number of things but I was not able to reproduce the error. However, I made a change to capture git errors a little better. Can you checkout the new error-report branch and compile/run this branch on your local machine? Then we should know what goes wrong on your end.

Thanks, this is interesting:

Call:
git --no-pager blame -L0,0 -l -s --show-number --show-name --porcelain >/Users/dcaunt/Projects/ShowInGitHub/Source/Classes/SIGPlugin.m

Output:

Version:
git version 1.7.10.2 (Apple Git-33)

xcrun shows a different version again:

$ xcrun git --version
git version 1.8.5.2 (Apple Git-48)

Looks like there is definitely a problem in my setup.

So I took a look at the plugin source and you're calling /usr/bin/git which is quite outdated. My git config contains a value which isn't valid in Git 1.7 (push.default = simple) and this causes the command to error. By changing my config, the plugin works as expected.

Perhaps the plugin would be more stable if it used xcrun git to run the git binary included in Xcode's app bundle rather than relying on the system git.

Thanks for the xcrun hint! I didn't know about this one. I will test the new version tomorrow and merge afterwards.
