removing very old commits (including initial)

removing very old commits (including initial)

[Mihamina Rakotomandimby]

Manao ahoana, Hello, Bonjour,

I work on a personnal project that become a little bit bigger over the
time.
Initially, it was a single file one, and that file contained database
credentials.
Later, I splat the project and put the credentials in another untracked
file (.gitignore).
When I want to publish this project, the history contains the initial
file, with the credentials. I dont want to publish that.

It's not a problem to definitely wipe the "single file" part of history
of this project, but interesting to keep the history after the
split&untracking.

How to?
Publishing will be through gitweb.

Misaotra, Thanks, Merci.

git-filter-branch(1) will do everything you need.

If I understand you correctly you want to publish only the commits
since a particular commit, say "newroot". You can do it with "git
filter-branch". You have many different filters, but in you case I
would you grafts to cut the history and the rewrite the history with
git filter-branch.

In .git/info/grafts you put something like this:
HashOfTheNewRoot

It means that this commit has no parent, so you are cutting the
history. You can examine the history with git log or gitk to check
everything looks fine. To make it definitive you have to execute git
filter-branch:

$ git filter-branch -- --all

--all in this case means all the refs.
