+To:	git@vger.kernel.org
+Date:	2005-11-08 1:31:34
+Subject: Real-life kernel debugging scenario
+Abstract: Short-n-sweet, Linus tells us how to leverage `git-bisect` to perform
+	bug isolation on a repository where "good" and "bad" revisions are known
+	in order to identify a suspect commit.
+
+
+How To Use git-bisect To Isolate a Bogus Commit
+===============================================
+
+The way to use "git bisect" couldn't be easier.
+
+Figure out what the oldest bad state you know about is (that's usually the 
+head of "master", since that's what you just tried to boot and failed at). 
+Also, figure out the most recent known-good commit (usually the _previous_ 
+kernel you ran: and if you've only done a single "pull" in between, it 
+will be ORIG_HEAD).
+
+Then do
+
+	git bisect start
+	git bisect bad master		<- mark "master" as the bad state
+	git bisect good ORIG_HEAD	<- mark ORIG_HEAD as good (or
+					   whatever other known-good 
+					   thing you booted laste)
+
+and at this point "git bisect" will churn for a while, and tell you what 
+the mid-point between those two commits are, and check that state out as 
+the head of the bew "bisect" branch.
+
+Compile and reboot.
+
+If it's good, just do
+
+	git bisect good		<- mark current head as good
+
+otherwise, reboot into a good kernel instead, and do (surprise surprise, 
+git really is very intuitive):
+
+	git bisect bad		<- mark current head as bad
+
+and whatever you do, git will select a new half-way point. Do this for a 
+while, until git tells you exactly which commit was the first bad commit. 
+That's your culprit.
+
+It really works wonderfully well, except for the case where there was 
+_another_ commit that broke something in between, like introduced some 
+stupid compile error. In that case you should not mark that commit good or 
+bad: you should try to find another commit close-by, and do a "git reset 
+--hard <newcommit>" to try out _that_ commit instead, and then test that 
+instead (and mark it good or bad).
+
+You can do "git bisect visualize" while you do all this to see what's 
+going on by starting up gitk on the bisection range.
+
+Finally, once you've figured out exactly which commit was bad, you can 
+then go back to the master branch, and try reverting just that commit:
+
+	git checkout master
+	git revert <bad-commit-id>
+
+to verify that the top-of-kernel works with that single commit reverted.

+How does the merge work?
+------------------------
+
+We said this tutorial shows what plumbing does to help you cope
+with the porcelain that isn't flushing, but we so far did not
+talk about how the merge really works.  If you are following
+this tutorial the first time, I'd suggest to skip to "Publishing
+your work" section and come back here later.
+
+OK, still with me?  To give us an example to look at, let's go
+back to the earlier repository with "hello" and "example" file,
+and bring ourselves back to the pre-merge state:
+
+------------
+$ git show-branch --more=3 master mybranch
+! [master] Merge work in mybranch
+ * [mybranch] Merge work in mybranch
+--
+++ [master] Merge work in mybranch
+++ [master^2] Some work.
+++ [master^] Some fun.
+------------
+
+Remember, before running `git merge`, our `master` head was at
+"Some fun." commit, while our `mybranch` head was at "Some
+work." commit.
+
+------------
+$ git checkout mybranch
+$ git reset --hard master^2
+$ git checkout master
+$ git reset --hard master^
+------------
+
+After rewinding, the commit structure should look like this:
+
+------------
+$ git show-branch
+* [master] Some fun.
+ ! [mybranch] Some work.
+--
+ + [mybranch] Some work.
++  [master] Some fun.
+++ [mybranch^] New day.
+------------
+
+Now we are ready to experiment with the merge by hand.
+
+`git merge` command, when merging two branches, uses 3-way merge
+algorithm.  First, it finds the common ancestor between them.
+The command it uses is `git-merge-base`:
+
+------------
+$ mb=$(git-merge-base HEAD mybranch)
+------------
+
+The command writes the commit object name of the common ancestor
+to the standard output, so we captured its output to a variable,
+because we will be using it in the next step.  BTW, the common
+ancestor commit is the "New day." commit in this case.  You can
+tell it by:
+
+------------
+$ git-name-rev $mb
+my-first-tag
+------------
+
+After finding out a common ancestor commit, the second step is
+this:
+
+------------
+$ git-read-tree -m -u $mb HEAD mybranch
+------------
+
+This is the same `git-read-tree` command we have already seen,
+but it takes three trees, unlike previous examples.  This reads
+the contents of each tree into different 'stage' in the index
+file (the first tree goes to stage 1, the second stage 2,
+etc.).  After reading three trees into three stages, the paths
+that are the same in all three stages are 'collapsed' into stage
+0.  Also paths that are the same in two of three stages are
+collapsed into stage 0, taking the SHA1 from either stage 2 or
+stage 3, whichever is different from stage 1 (i.e. only one side
+changed from the common ancestor).
+
+After 'collapsing' operation, paths that are different in three
+trees are left in non-zero stages.  At this point, you can
+inspect the index file with this command:
+
+------------
+$ git-ls-files --stage

+------------
+
+In our example of only two files, we did not have unchanged
+files so only 'example' resulted in collapsing, but in real-life
+large projects, only small number of files change in one commit,
+and this 'collapsing' tends to trivially merge most of the paths
+fairly quickly, leaving only a handful the real changes in non-zero
+stages.
+
+To look at only non-zero stages, use `\--unmerged` flag:
+
+------------
+$ git-ls-files --unmerged
+100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1	hello
+100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2	hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
+------------
+
+The next step of merging is to merge these three versions of the
+file, using 3-way merge.  This is done by giving
+`git-merge-one-file` command as one of the arguments to
+`git-merge-index` command:
+
+------------
+$ git-merge-index git-merge-one-file hello
+Auto-merging hello.
+merge: warning: conflicts during merge
+ERROR: Merge conflict in hello.
+fatal: merge program failed
+------------
+
+`git-merge-one-file` script is called with parameters to
+describe those three versions, and is responsible to leave the
+merge results in the working tree and register it in the index
+file.  It is a fairly straightforward shell script, and
+eventually calls `merge` program from RCS suite to perform the
+file-level 3-way merge.  In this case, `merge` detects
+conflicts, and the merge result with conflict marks is left in
+the working tree, while the index file is updated with the
+version from the current branch (this is to make `git diff`
+useful after this step).  This can be seen if you run `ls-files
+--stage` again at this point:
+
+------------
+$ git-ls-files --stage
+100644 7f8b141b65fdcee47321e399a2598a235a032422 0	example
+100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 0	hello
+------------
+
+As you can see, there is no unmerged paths in the index file.
+This is the state of the index file and the working file after
+`git merge` returns control back to you, leaving the conflicting
+merge for you to resolve.
