Subject: git bisect start on a tag revision fails
Message-ID: <3f4fd2640802100301y436bda41kcca1b1eb8ec0ea10@mail.gmail.com>

Hi,

When hunting bugs with the wine source code
(git://source.winehq.org/git/wine.git), both Dan Kegel and I have
found the following berhaviour with git bisect:

$ git checkout wine-0.9.54
HEAD is now at 8f954cc... Release 0.9.54.
$ git bisect start
fatal: ref HEAD is not a symbolic ref
Bad HEAD - I need a symbolic ref

Whereas doing:

$ git checkout master
$ git bisect start

then:

$ git checkout wine-0.9.54
$ git bisect good

works.

Is it possible to have bisect support non-symbolic refs?

- Reece
