Hi!
I was trying to do a git bisect on 2.6.22-git6 and 2.6.22-git8. For which I get following error :
root@amit:/usr/src/linux-git # git bisect good v2.6.22-git6
Bad rev input: v2.6.22-git6

The repository is obtained by :
root@amit:/usr/src # git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 linux-git

I am running following git version on Debian Sid, updated today.

# git --version
git version 0.99.8.GIT
'# dpkg -l | grep git' shows ' git-core 1:1.5.2.3-1'

I tried searching man-pages/documentation/website but couldn't find any references to git bisect on -git kernels. I would be grateful if anyone can help me find what's going wrong.

As I am not subscribed to the mailing-list, please cc me to all the messages on the thread. Thanks and Regards,

There is a very old GIT version in your PATH (version 0.99*), which takes preference over the version from sid.

Hello,

Quoted 2 lines

# git --version
git version 0.99.8.GIT

this doesn't match

that. Maybe you should build your own git packages. Lucky you that it is pretty easy with debian. Have a look at this thread:

	http://groups.google.com/group/linux.kernel/browse_thread/thread/b8509269407c0fdc/d05d0547e7dfcf03?lnk=st&q=author%3AThomas+author%3AGlanzmann+git+linux.kernel&rnum=1#d05d0547e7dfcf03

especially the first post (scroll up).

This struck me as being weird, but I thought 'git' utility version is different than the package. My mistake! :)

I didn't build my own git version. What I did do was to remove the old git and ensure I am using the Debian installed one.

Now I am getting a different error :
root@amit:/usr/src/linux-git # which git /usr/bin/git
root@amit:/usr/src/linux-git # git --version
git version 1.5.2.3
root@amit:/usr/src/linux-git # git bisect good v2.6.22-rc6 root@amit:/usr/src/linux-git # git bisect bad v2.6.22-rc8
fatal: Needed a single revision root@amit:/usr/src/linux-git #

A quick search on the net didn't yield anything. Please help me find out what's going wrong. Thanks and Regards,

I should call it a day. Above commands are wrong. I need to work on -git kernels and not -rc kernels (as the above commands are showing). I am still getting the same errors I started with :

root@amit:/usr/src/linux-git # git bisect good v2.6.22-git6 Bad rev input: v2.6.22-git6 root@amit:/usr/src/linux-git # root@amit:/usr/src/linux-git # root@amit:/usr/src/linux-git # git bisect good v2.6.22-git8 Bad rev input: v2.6.22-git8

The -git# is added by a script and does not exists as tags. The same place where you retreive the -git files has a file identifying the commit that is the latest - use the SHA of this and you should be happy.

The -git snapshots are made automatically by kernel.org, and their name is not included in the git repository. You could create tags for them like this:

git tag v2.6.22-git6 8f41958bdd577731f7411c9605cfaa9db6766809 git tag v2.6.22-git8 a5fcaa210626a79465321e344c91a6a7dc3881fa

... and afterwards you can use those revision names with bisect (or other git commands). I've got the commit IDs (i.e. those mysterious 40 hex digits above) from the first line of the changelogs; their URLs are:

http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.22-git6.log

You need to start off by saying

to set up the necessary infrastructure.

you seem to be missing a "git bisect start" from that sequence ... see the man page for more details.
