How in tarnation do I git v2.6.16-rc2? hg died and I still don't git git

[Paul Jackson]

I'm trying to git a copy of Linus's tree, checked out only up
through revision v2.6.16-rc2, so that I can lay down Andrew's
latest broken-out quilt patch set for 2.6.16-rc2-mm1 on top of it.

I had been using hg (mercurial) to keep a current copy of Linus's
tree, and to make hg clones at each 2.6.*-rc*, to which I would apply
Andrew's various 2.6.*-rc*-mm*.

But the hg tree seems to have died on me, and I still don't git git.

I can do:

    git pull rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

and get Linus's tree as of the latest change, and I can do a "git log",
and see that I want a clone (in the hg sense, not the git sense) of
this tree as of:

    commit 826eeb53a6f264842200d3311d69107d2eb25f5e
    Author: Linus Torvalds <torvalds@g5.osdl.org>
    Date:   Thu Feb 2 22:03:08 2006 -0800

	Linux v2.6.16-rc2

Once I have that clone of Linus's tree at this revision, I am happy
using quilt to push Andrew's 2.6.16-rc2-mm1 that I ftp'd from:

    ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc2/2.6.16-rc2-mm1/

on top of this.

But how in tarnation do I git a checked out copy/clone/whatever of
Linus's tree that only has the changes up through revision v2.6.16-rc2
(that doesn't include changes since then)?

git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6
cd linux-2.6
git-checkout -b v2.6.16-rc2 v2.6.16-rc2

I usually create a branch for each -mm release and add there all the
patches, eg:
	git checkout -f -b v2.6.16-rc2-mm1 v2.6.16-rc2

then do something like:
	while [ $(quilt next) ] ; do \
		quilt push && git add && git commit -a -m "$(quilt top)"; \
	done

as an alternative you canprobably checkout HEAD and git-reset --hard to
the wanted commit.

Hi Paul,

You create a branch.   This will be a bit easier if you have all of the
tags for each of Linus' releases, do:

$ git fetch --tags

Then you create the branch as at the commit you're interested in:

$ git checkout -b working v2.6.16-rc2

Which tells git to create a branch named "working" as at the commit
referenced by the tag "v2.6.16-rc2".   You can see this worked
by:

$ git branch
  master
  origin
* working

Where the asterisk shows you that you're now operating in the "working"
branch.   And "git log" will show you that the HEAD commit is the
one you're interested in.

HTH,
Sean

Using Mercurial, pull from here instead:

hg pull http://master.kernel.org/hg/linux-2.6

That works.

On another thread, Matt Mackall asks we not change
our default URL to the above master.kernel site,
as it has much less bandwidth.

And he says he should have the recommended site
back up shortly:

	http://www.kernel.org/hg/linux-2.6

Hi Paul,

I had a similar problem yesterday and was pointed at
https://wiki.ubuntu.com/KernelGitGuide?highlight=%28CategoryKernel%29
as a starting point.

I was thinking it would be really nice if someone fancied writing a
git guide for dummies (like me) who only use git on and off. Something
that could be put either on git.kernel.org or a similar place.

Things like how to do basic checkouts, how to revert back to a certain
snapshot or a certain commit id, how to use git-bisect to track
breakage and other basic stuff.

Anyone looking for a pet project who fancies writing up something like
this? I can say for sure that it will be appreciated.

Cheers,
Jes

Any reason that doesn't use the git:// protocol?  It'll fetch the tags
for you, etc.  And I think it's the "preferred" way of using git when
working with the kernel.

Hi Jeff,

Thanks, I'll add that to my bookmarks as well, but it's still missing
some important stuff, like how to roll back to a specific commit id
and git-bisect ;-) It seems a bit more targetted towards being a git
tree maintainer than a client.

Having some of this linked off git.kernel.org would be wonderful too
since at least for me seems to be the most logical place for anyone to
start looking for info.

Thanks,
Jes

I did.  I spent some time reading it, as one of
the best git howto's I could find.

Me and the git UI just weren't met to be.

If you've ever used Quilt (even if you haven't), try StGIT -
http://www.procode.org/stgit/, it might suit you better (IIRC, you
tried it already but were not happy with the first version; it is much
improved now :-)).

That is a nice guide, but is oriented to developers, I think jes
was asking from a user POV (I've needed to google for such things
several times) ie how to switch to a given tag and return to master,
how to update the repository periodically, etc; no stuff about how to
manage patches. It may be nice to see such thing on your guide, something
like this:


- How to get a copy of linus'tree
  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

- Update your copy:
  cd linux-2.6; git pull; git pull --tags

- How to go back to a certain snapshot
  git reset --hard v2.6.13 (ls .git/refs/tags to see all the tags). Not the
  cleanest method, I think. "git-checkout -f master" will return to the "head"
  of the repository. You can also pass commit-IDs to git-reset instead of tags?

- bisect search
  git reset --hard BrokenVersion
  git bisect start
  git bisect good v2.6.13-rc2
  
  Compile, test, and do "git bisect good" or "git bisect bad" until you find
  the culprit. If it doesn't compile or something you can do a "git bisect good/bad"
  "git bisect reset" resets the repository when you are done.
  http://www.kernel.org/pub/software/scm/git/docs/howto/isolate-bugs-with-bisect.txt
  explains it with more detail.

Diego,

Yup thats pretty much it. My usage of git upto now has pretty much
been:

quilt pop -a
git-pull
quilt push -a
<rebuild>

Suddenly something broke with the git-pull and I needed to track down
which change it was.

Cheers,
Jes

Note just the one "git pull" seems to fetch tags on its own now without
need for the last step.

If you intend to do apply patches against that particular version, you
could also create a new branch:

	git checkout -b my-v2.6.13-branch v2.6.13

or if you know from the start that you only want to update up to a
certain version,

	git pull tag v2.6.13

instead of just "git pull".

I did some work on a new tutorial under Documentation/tutorial.txt in
the git source tree:

http://www.kernel.org/pub/software/scm/git/docs/tutorial.html

which might be helpful, though it isn't so specifically targetted at the
case of linux testers.  It wouldn't be hard to write something like
that, though.  Git should make that kind of use pretty easy.

Thanks for the git guide links.

I spent some time reading them yesterday (not the Ubuntu
one you pointed to, but others.)

After repeated efforts, beginning with the birth of git,
it is clear that I have some sort of congenital mental
defect that makes me unsuited for using git.

Hopefully someone benefited from your links.

Hey Paul, welcome to the club, you're not alone :-)

Every time I use it, I spend more time fixing my mistakes
than doing useful work. I'm at the point of doing a "cp -a"
before starting anything because it too often gets very bad
after a few operations. Even git-reset often fails for me.

I think that the biggest problem is that it's not intuitive,
so if you don't use it often, it's hard to remember all the
tricks. Anyway, there are so many people happy with it that
I think that *we both* have mental defects. BTW, have you
tried cogito ? Not much more intuitive, but at least, it
reduces the number of commands for some basic operations,
and this sometimes leads to less mistakes.

I did the opposite : I tried hg as soon as Matt announced it, but I
got lost in the "python dumps" which appeared at the slightest error,
because I did not understand what the problem was. Then I tried git,
at least to be able to keep in sync with Marcelo. With git, I had
some opportunities to catch some understandable error messages spit
out of some shell scripts even when not caught by the script itself.
But using it less than twice a week requires me to read the manual
again before doing anything useful :-(

Mercurial has gotten a lot better about "python dumps" as a signal
that you had typed something wrong, or had permissions problems, etc.
I got annoyed about that too, but I just learned to ignore them and
assume that 90% of the time, it was due to a mistake on my end.
Things are a lot better there; claiming mercurial sucks for its early
rough edges is about as far as claiming that git sucks because its
performance sucked rocks on laptop drives in its early days before
Linus added support for packs.
