[gentoo-dev] Git Migration: launch plan & schedule (2015/Aug/08-09)

[Robin H. Johnson]

[-- Attachment #1: Type: text/plain, Size: 725 bytes --]

Hi all,

The Git migration is moving forward, and I'd like to announce a
tentative schedule for that end.
https://wiki.gentoo.org/wiki/Project:Infrastructure/Git_migration#Status

2015/08/08 15:00 UTC - Freeze
2015/08/08 19:00 UTC - Git commits open for developers
2015/08/09 01:00 UTC - Rsync live again (with lagged changelog)
2015/08/11           - History repo available to graft
2015/08/12           - rsync mirrors carry up-to-date changelogs again

I've allocated time for an 8 hour freeze, but hope to be completed much
sooner than that.

Sounds good.  Thanks to all the hard workers out there.

Does this mean that https://wiki.gentoo.org/wiki/Gentoo_git_workflow
is no longer draft or needs work or another document is meant to
display the new flow?

It does cover most of the things needed.

It could use some revision regarding gkeys, and I'd like to also mandate
signed pushes in addition to signed commits.

I doubt I'm the only one who assigned a well under 50% chance of actually 
seeing it happen, believing gentoo was ultimately destined to become a 
Linux historical footnote due to failure to switch to git!  I've been on 
gentoo over a decade, now, and stuck on CVS, I honestly didn't know if 
it'd last another.

Obviously, I'm VERY glad to see the git switch actually scheduled! =:^)

Thanks... just isn't a sufficient word to convey my gratitude to all the 
folks that have been working on this.  Seriously.  This switch to git 
puts you up with the gentoo greats such as DRobbins, in my book.  Because 
without it, let's face it, gentoo /was/ slipping ever so slowly into 
history, and this really does, I believe, give us a chance to turn that 
around.

historical news!

This is great news! I assume docs have been written for git-commit
standards as well?

Why that? rsync is and will be the default sync method. We are switching for
development not the sync clients.

Thanks to all who helped to make this possible! :-)

Are there still any plans to use a code review system like gerrit that
will avoid merges, rebases etc. to the tree by just accepting and
serializing patches?

A push doesn't create any data, it just uploads it to the repo, so how
do you sign a push?

Repoman may need to be adjusted. Git commit has support for a "-S"
flag which signs the commit.

Oh, you said push specifically, instead of commit.  My apologies.  I'm
unaware of a means to do this.  I guess you could theoretically sign
and commit a list of the pushed commit hashes.

No that is different. There are two signing things involved here.
1) git commit -S. ie sign the commit in the tree, and git log will show
that signature later.

2) git push -S, this is signing the push itself. The client will sign
everything that it pushes to the server. Then the server can verify that
it was pushed by a dev (which is different from the commit since a dev
might be pushing a commit that was made by a user). The server will save
this push certificate so that it can also be verified later on.

We'll want to have both of these on. It may require some repoman changes
but should not be that much.

As I see from git docs only commits and tags may be signed. There
is no way to sign a push. Moreover there is no need to sign each
commit, see what Linux says on that:
http://git.661346.n2.nabble.com/GPG-signing-for-git-commit-td2582986.html

''
Btw, there's a final reason, and probably the really real one.
Signing each commit is totally stupid. It just means that you
automate it, and you make the signature worth less. It also doesn't
add any real value, since the way the git DAG-chain of SHA1's work,
you only ever need _one_ signature to make all the commits
reachable from that one be effectively covered by that one. So
signing each commit is simply missing the point.

This was new to me, but check out the "--signed" flag of git-push (1).

I think the next sentence is relevant:

  IOW, you don't _ever_ have a reason to sign anything but the "tip".

My interpretation is that it doesn't make sense to sign commits one
through nine if you're going to sign the tenth before pushing. But most
of our commits are small and self-contained so it's probably easier to
automate the signing with repoman than it would be to come up with a
to-sign-or-not-to-sign guide a mile long.

Newer version(s) of git do have git push --sign capability.  Sorry, I
don't know the versions that it applies to. It was recently added as a
feature. It also makes the push sig and data readily available for hook
use.

That was Linus's 2009 opinion, and he changed his mind since then, with
the research into further attacks on SHA1.

Git (since 2.2) DOES support signed push. Look at the manpage for
git-push, for the --signed option:
http://git-scm.com/docs/git-push

The point of signed commits is to authenticate the creator of each
commit.

The point of signed pushes is to authenticate who introduced a commit
(it might NOT be the person who signed the commits) and intended it to
be on a specific branch.

A slightly out of date, but good backgrounder on signed commits is here:
http://mikegerwitz.com/papers/git-horror-story

The StackOverflow asking about signed push is a good reference as well:

We have a rule of "one year compatibility period". ChangeLog shows
that git-2.2.0 was introduced on 02 Dec 2014. So pushed commits
can't be enforced before 02 Dec 2015. (And yes, my laptop
still uses an older version, that's why I was unable to find --sign
in the git-push manual.)

A few things.  I agree with where you're going, Robin, but I do take
issue with just one bit of your email.

First, signing commits in no way protects against attacks on SHA1.
The only thing that binds a commit record to the actual data in the
tree is an SHA1 hash.  If you are able to break SHA1 then all you need
to do is tamper with a file in the tree however you want, then add or
tamper with another file anywhere else in the tree such that the two
changes "cancel each other out" and result in the same SHA1 hash.
Then you swap out any blobs/trees you modified in the repository and
nobody is the wiser, especially with something like Gentoo where you
can stick something in a random filesdir anywhere in the tree where
nobody will notice it for a long time.  The commit record itself is
not touched, so its signature verifies just fine.

That said, I do support commit signing. It makes a lot more sense for
a project like Gentoo than a project like Linux.

With Linux, the distributed repositories everybody actually uses have
only one committer each for the most part.  The only person who
commits to mainline is Linus himself.  Then there is a release process
where all the commits for the week go out with a git tag, which is
signed.  Linus basically does the final QA on the mainline kernel
before it is released, and he assumes responsibility for every commit
that went into it.

In contrast, Gentoo has numerous committers and changes go right from
the dev's repository to every user's desktop.  When I make a commit
I'm only responsible for my own change - I don't do QA on the last 47
commits other random devs have made.  So, if the last commit doesn't
interact with mine in any way, chances are I won't do any testing of
it at all before I add my own signature - I won't even run repoman on
the entire tree.  So, a dev's commit signature is really a stamp of
quality on the diff between their commit and the last, not the tree as
a whole.  So, it really makes sense to the signing at the commit
level, and not at some higher level.  In fact, to do the signing at a
higher level really does amount to rubber-stamping changes in a way
that commit signing does not, based on how we assign responsibility.

If we were a release-based distro then tag signing would be much more important.

Finally, signing commits is really cheap, so why not just do it?

In general we try to avoid breaking the upgrade path for user systems
that only upgrade annually, but no such limitation applies to
developers.  I don't think it is too much to expect a developer to use
a recent version of git.  Users don't need git push signing support to
use Gentoo.

By all means debate the importance of the feature/etc, but I don't see
a need to freeze any new git feature for a year before making use of
it with the gentoo repository.

If it really bothers you, do your pushes from a chroot.  It isn't like
I close any gcc-5 bugs with "can't be bothered to look at gcc-5 - give
me a call in a year or two."

This is going live in a few minutes. There was a lot of delays and snags
that were hit. QA has a lot of reviewing to do of in-tree patches with
long-standing CVS keyword damage. gkeys is also not sufficiently baked,
so we're using some scripting for now instead [1].

The new setup DOES enforce that commits AND pushes are signed.

I'm only 90% sure that everything works, but I've spent almost the
entire day on it, and there's more to go tomorrow.

Other old CVS repos are still closed for the moment, they will re-open
tomorrow.

These parts are still pending.

Quick instructions:
Set PORTAGE_GPG_KEY="0xLONG-GPG-KEY" in your make.conf
$ git config user.signingkey 0xLONG-GPG-KEY
$ git clone git+ssh://git@git.gentoo.org/repo/gentoo.git
$ vim ...
$ repoman commit -m '...' [2] 
$ git push --signed

(some time later, when you have local unpushed commits you want to
rebase instead of merging)
$ git pull --rebase -S
$ vim ...
$ repoman commit -m '...'
$ git push --signed

(some time later, when you have a local branch you want to merge)
$ git merge -S some-branch
$ git push --signed

[1]
The keys as they are in LDAP right now have been used. If you need to
change your key, please ping infra as well, so I can update the
temporary setup.
$ ldapsearch 'gentooStatus=active' gpgfingerprint -Z -LLL \
	|grep gpgfingerprint |cut -d: -f2- |tr -d ' '  \
	|grep -v 'undefined'  | xargs gpg --recv 

[2]
If you commit directly with "git commit" you MUST pass -S (and ideally
-s).

Thanks a lot!

use case: my cvs tree had uncommitted ebuild work (yes, you caught me
actually doing something).
now `cvs diff` no longer works, how can i track down my local changes?
besides diffing against git tree, brain memory aka shell history and

I'd say: 

- tar your *.ebuild and files/* stuff away
- then "git clone" the new git repo.
- untar your files in the new git repo
- use "git diff"

there will be a ton of cvs keyword noise in there though.  need to run
a sed on the files to clear it out.

it also will include noise where your local checkout was behind the latest
tree, so it'll only really work if you ran `cvs up` in the whole tree just
before it was shutdown.

Out of curiosity, is it impossible to have a read only CVS server with
the state at the time of the freeze?

So for someone who hasn't been following any of this, is there an idiot's guide
on how make the Gentoo?

Seconded here. Read-only CVS should not consume much resources, but
will facilitate migration.

2 questions:

1) The git workflow [1] does not mention to add PORTAGE_GPG_KEY to make.conf 
and neither to use the long gpg key. Does the short create a problem?

2) The git workflow [1] says to do git config --local commit.gpgsign 1 - Do we 
need to use git push --signed if was already in the config ?

I'm asking just for have an up-to-date documentation, and maybe add all the 
notes there.

Thanks.

Robin's set of insns had everything i needed to get going, and i've never
done git signing before

the only thing to note is that our documentation has generally said you
should generate a dedicated key for signing (with a short expiration),
but the set of gpg keys in ldap generally have been your long-lived key
that you use for e-mail/etc...  so if you followed that, your ebuild key
won't be in ldap (so add it using the ldap wiki guide), and you'll have
to wait for the keys to be synced by infra before you can push.

what were you having trouble with ?

Hi all!

Current repoman complains about headers in ebuilds

>>> Creating Manifest for /home/alexxy/Gentoo/gentoo/sys-cluster/open-mx
   ebuild.badheader              1
    sys-cluster/open-mx/open-mx-1.5.4.ebuild: Malformed CVS Header on 
line: 3

So may be its better to drop $Id: $ completely?

Since repoman do comparison with header.txt which contains


alexxy@x240 ~/Gentoo/gentoo $ cat header.txt
# Copyright 1999-2015 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $

So we can change last line to $Id$ or since it dont actualy needed we 
can simply drop it.

We shouldn't do anything (besides adapting repoman to the $Id$ format)

Do we really need to have ANY keywords in our files?  Keyword
expansion was just a PITA all-around with cvs.  Do we really need to
embed them in our git files?

At least git doesn't expand them in the actual repository.

I'm not really a big fan of any kind of in-band signaling.  I guess
the one advantage of this is that if you find a file OUTSIDE of a
repository you know where it came from, but how important is that?

The expansion is ONLY for the rsync export, so that we can identify the
version of the file on a user's system.

When previously discussed, that was a strongly requested item, as
developers DO sometimes ask users to please test rev 1.xyz of an ebuild.

It seems you have one final use for my "cvs-status" script. That will
do an offline status check by comparing timestamps.

I'd like to thank you and anyone else who's worked on the Git
migration. It's not a trivial undertaking and I look forward to
working on ebuilds with Git! The workflow wiki page is very helpful;
I've added it to my Watchlist so I can stay up to date on changes.

Thanks again for your efforts! If you'd like any assistance in setting
up hooks, I'd be glad to help.

Read-only access to gentoo-x86 is restored (and write to the other CVS
repos).

Any news on when git repo with historical commits will be
available? Or am I missing something and it is already online?

Having rsync mirrors with up-to-date ChangeLogs will be great too :)

I have no news on anything official but I've posted one at:
https://github.com/gentoo/gentoo-gitmig-20150809-draft

I'm not aware of any issues with it, but let me know if you see any.
With git-replace we can of course fix it as many times as we need to.
