sync.pl (Git) is examining all commits all the time about bugzilla-vcs HOT 5 OPEN

Hmm, but Git is a DVCS, how can I know that you didn't do some sort of crazy 
merge or backing-out or switching branches, etc.?

This is what I did:

mkdir test
cd test
git init
touch test.txt
git add .
git commit -m"one"
git log
echo "First line of code" >> test.txt
git add .
git commit -m"two"
git log
git branch crazy
git checkout crazy
echo "Second line of code" >> test.txt
git add .
git commit -m"crazy one"
git log
git log 46ba136687..           {this is commit "one"}
git checkout master
git merge --no-ff crazy
git log
git log 46ba136687..           {this is commit "one"}


The log shows info as expected.
I didn't test any "crazy" stuff. Limited knowledge of git :(.

Oh, no, I wasn't accusing you of doing crazy stuff. I was saying in general, I 
need to rescan the whole repository, because I can't know what the user has 
done with it.

I understand and I didn't think you accused me of anything :)

What I tried to demonstrate is that when you branch and merge, "git log from.." 
will show the comments from withing the branch as well.

The only problem I see (with my limited knowledge of git) is when you have 
stored commit id 46ba136687 in DB and someone removed that commit from the 
repo. In that case "git log 46ba136687.." will tell you that such commit 
doesn't exist and I guess will return -1 which would trigger full scan?

Ah, it's actually worse than that. You could change the HEAD pointer to point 
to another branch with an identical commit at the top but different commits 
underneath it.
