fatal: Not a valid object name master

[medamin25]

hi, iget this error while running git fame perhaps my branch is main .
a workaround that is to use --branch arg like git fame --branch main .

• I think it 's better to detect the active git branch by default.

running:

$ sh -xc "uname -a ; git fame --version ; git fame " |& sed -ure 's/^(\+\s+)/\n\1/;$s/$/\n/'

output:

+ uname -a
Linux f6c2c582ccf8 5.15.0-1016-gcp #21~20.04.1-Ubuntu SMP Fri Aug 5 12:53:07 UTC 2022 x86_64 GNU/Linux

+ git fame --version

+ git fame
Error: Could not run 'git --git-dir='/home/runner/leafserver/.git' --work-tree='/home/runner/leafserver' ls-tree -r master --name-only' => fatal: Not a valid object name master.
Try --help for help.

workaround

$ git fame --branch main

like #84 by @kannanbalu but it 💯 work with --branch=any_existant_git_branch (or --branch any_existant_git_branch)

$ git fame --branch main

running:

$ sh -xc "uname -a ; git fame --version ; git fame ; git checkout -b development ; git checkout -b mmm ; git branch ; git fame --branch=main >/dev/null ; git fame --branch=mmm >/dev/null ; git fame --branch=development >/dev/null ; git checkout -b master ; git fame >/dev/null ; git fame --branch=master >/dev/null" |& sed -ure 's/^(\+\s+)/\n\1/;$s/$/\n/'

me also like @MrShoenel in this comment:

When I run git ls-tree -r HEAD --name-only on my own, I get a list of all tracked files, so it's not Git that fails.
And yes, C:/repos/my-repo and C:/repos/my-repo/.git exist. It is a valid repository. I guess I am getting some concealed error here..

both commands git ls-tree --name-only HEAD ; git ls-tree -r HEAD --name-only work for me.

Also i remark, that git-fame and when branch master exist, always work on branch master even if current branch not master.

• so, i think that branch master is hard coded somewhere in code.
  I found that --branch option not hard coded and has a default value of HEAD. So why? 😮

[oleander]

There might be some reference to master somewhere within the code base, but I agree that it should use the current branch rather than master.

I'm open for a PR ツ
