Hello,
I'm trying to use 'git bisect' and am running into the following error:
[mason@hawaii linux.git]$ git bisect reset
[mason@hawaii linux.git]$ git bisect start
[mason@hawaii linux.git]$ git bisect good
d166b5a220813a08a79312fc384d11e1c57e9072
[mason@hawaii linux.git]$ git bisect bad
a7900c9bdb64c11688719bef9f6373fbc4c276ab
Bisecting: 116 revisions left to test after this
fatal: Entry 'block/elevator.c' would be overwritten by merge. Cannot
merge.
(this is the linux-mips.org kernel repository, a7900c9b is a child of
d166b5a2).
What does this mean? How do I get around it?
As you can probably guess, I'm a beginner to git bisect.
Thanks in advance.
Mark

This seems to mean that you have a dirty block/elevator.c file. Have you
perhaps edited it?

I thought of that, but even removing the workspace file doesn't get
around this:
[mason@hawaii linux.git]$ git bisect reset
[mason@hawaii linux.git]$ git bisect start
[mason@hawaii linux.git]$ git bisect good
d166b5a220813a08a79312fc384d11e1c57e9072
[mason@hawaii linux.git]$ git bisect bad
a7900c9bdb64c11688719bef9f6373fbc4c276ab
Bisecting: 116 revisions left to test after this
fatal: Entry 'block/elevator.c' would be overwritten by merge. Cannot
merge.
[mason@hawaii linux.git]$ rm block/elevator.c
[mason@hawaii linux.git]$ git bisect bad
a7900c9bdb64c11688719bef9f6373fbc4c276ab
Bisecting: 116 revisions left to test after this

I've made no commits to this tree - it's just an up-to-date pull of the
linux-mips.org tree. I also have no local edits at this point.
[mason@hawaii linux.git]$ git diff
[mason@hawaii linux.git]$
What's puzzling me is that (as I understand it) git bisect simply
manipulates the workspace, not the repository.
Thanks!
Mark

That doesn't necessarily help. Removing the workspace file potentially
just makes the workspace even _more_ dirty, rather than less. It makes git
think you've edited the file that it wants to check out another verion of.
(Of course, an extra file can _also_ be a sign of being dirty, so
sometimes removing such a file _does_ generate a "more clean" tree).
Basically, "dirty" means that it doesn't match the head commit.

Well, it doesn't _change_ the repository, but it does move around in it,
using "git-read-tree -u -m". That can error out if the old tree and the
new tree differs in a particular file, and the workspace doesn't match the
old tree in that file.
Now, it could be a git bug, but before you go there, try to make sure tat
your tree is really clean. Do a
git checkout -f master
followed by "git status" to make sure that the workspace is clean (no
unexpected untracked files, no diffs against HEAD, no nothing). The "git
checkout -f master" should have cleaned everything up, but it won't
actually touch extra files that it doesn't know about, so..

That did the trick. Thanks very much for the pointer, it's much
appreciated.
Thanks,

Thanks, both of you. This got me worried, especially when I am
at work and cannot pull the whole mips tree to take a look at it
myself.
