Hi,

I was just trying out the new gitk feature that shows you the origin of a
selected line in the diff pane and found that it doesn't work right if
gitk is not started in the top-level work directory - i.e. if you are
in a subdir it pops up an error message of this form:

Error running git blame: fatal: no such path $path in $sha1

I guess it needs something like subdir-depth number of ../ prepended to
the front of the pathname to make the blame succeed.

I could try and fix this but I am sure that others who understand
the sources of gitk/git-blame/git can do it much quicker than me.

Cheers,

Mark

Hi,

I think the same problem exists with the 'run git gui blame on this
line' feature. It doesn't work when gitk is started in a subdir of the
working tree but it does work when gitk is started in the top-level
directory.

Cheers,

Mark

I have checked in a fix into my gitk.git repository at
git://git.kernel.org/pub/scm/gitk/gitk.git.  However, there seems to
be a bug in git gui blame; it gives a "list index out of range" error
sometimes.

Shawn, to see an example of the error, get a current kernel tree and
do:

$ cd arch/powerpc
$ git gui blame --line=1183 2c5e76158fcea6e3b9536a74efa7b5e2e846d374 \
  ../../net/sunrpc/svcsock.c
