They do under GIT. No matter how much you criss-cross, every time you
identify a merge base for the next merge, you are identifying the last
commit in common on both branches.
While maybe you didn't have that commit being the tip of a head in
your repo, it _is_ the last common point. If your criss-crossing is
messy and a few commits are out of order or cherry picked, git-merge
has a good chance of spotting it. The whole mechanism tends pulls
quite consistently towards convergence.
If the notes in the commit msg aren't consistent and we lose the
natural tendency towards convergence that's a major drawback. On the
other hand, if two branches have exchanged patches "out of band",
git-merge still gets it right most of the time, so perhaps slightly
different headers in the commit messages are tolerable?

I really don't like that -- goes against the grain of really simple,
portable repos. I cp -pr repo{,_tmp} all the time to do risky merges
or save a heavy download from a remote server. Let me run away from
this idea... quick before Linus kills us all ;-)
I did feel a couple of times the need of remembering where I had
checked this in -- but it went away quite quickly, must have been a
leftover of my Arch days ;-). And it actually got solved by agreeing
within my team to a commit message format pretty much like what's used
in the kernel. Because the truth is that most of my heads and branches
have very "local" names.

Probably you should update to at least linux-v2.6.15-g117a93d. The
script to determine the localversion[1] depends on .git/HEAD being a
symlink.
Since
git-1.1.4-g2fabd21
.git/HEAD isn't a symlink any more (per default at least).
You can rebuild git with USE_SYMLINK_HEAD if you really want the old
behaviour.

I am not sure what the focus of the above description is. I
myself got more confused after reading it than before ;-). My
impression was that we have been using the word "cherry-pick" in
pretty standard way, but are you trying to stress that we use
the word in a different sense?
"Action of selecting" is done by the user, perhaps with or
without help from the tool. After deciding which one to "port",
the way to perform the actual "port" would be different from SCM
to SCM, and in GIT it is often done with the "git-cherry-pick"
command. Are you saying the command is misnamed, and we should
call a program that helps the user in "action of selecting"
cherry-pick (actually, I think "git cherry" fits that
description)?
If the focus is not to highlight the distinction but to help the
end user, something like this might be better.
cherry-picking::
In SCM jargon, "cherry pick" means to choose a subset of
changes out of a series of changes (typically commits)
and record them as a separate series of changes on top
of different codebase. In GIT, this is performed by
"git cherry-pick" command to extract the change
introduced by an existing commit and to record it based
on the tip of the current branch as a new commit.

* [PATCH] cache-tree: replace a sscanf() by two strtol() calls
From: Johannes Schindelin @ 2006-05-02 1:31 UTC (permalink / raw)
To: git, junkio
On one of my systems, sscanf() first calls strlen() on the buffer. But
this buffer is not terminated by NUL. So git crashed.
strtol() does not share that problem, as it stops reading after the
first non-digit.
Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de>

Maybe, a better solution would be to store the integers in
binary form. But I am not familiar with that part of git, and
further, it would break setups which already have an index
with cache-tree information.

Here I'm a little bit confused still. Surely criss-crossing branches
already don't converge unless the commits are in the same order.
Oh, I see. Even if they *are* in the same order, the commit IDs would
end up different due to these extra headers.

That sounds reasonable. The UUID doesn't need to replicate, either, just
tag the commits that were made against it.
This extra information falls into the informational, "forensic" history
tracing category. ie, we don't know now whether we'll need it, but we'll
store it anyway just to be sure to not make later operations impossible.
I think the large remaining question is around what conventions apply to
the use of the "note" field. We have perhaps the first example of a well
formed piece of "forensic" information that belongs in the commit chain
and could possibly be added by plumbing. I can't think of any more of
those, but the rename/copy tracking case is a bit different. In this
case, it doesn't belong in the plumbing, yet you want a reasonable
convention for storing this information to apply. Also the other cases
outlined in the original post might do well to have a common convention
so that the information is more portable between porcelain.

* [PATCH] builtin-grep: do not use setup_revisions()
From: Junio C Hamano @ 2006-05-01 23:24 UTC (permalink / raw)
To: Linus Torvalds; +Cc: git
In-Reply-To: <7v64kpsftv.fsf_-_@assigned-by-dhcp.cox.net>
Grep may want to grok multiple revisions, but it does not make
much sense to walk revisions while doing so. This stops calling
the code to parse parameters for the revision walker. The
parameter parsing for the optional "-e" option becomes a lot
simpler with it as well.

So I did this. This removes the ability to say:
git grep master..next -e foobar -- Documentation
but if you want to walk the revision graph, you are interested
in commits that actually changes things to be subject to grep,
not just all commits in the range, so if that is what you are
doing, you are better off using the pickaxe.

unpack tries to unpack and if it already has the object it
skips.
If you really wanted to do it, here is a way to do so.
mv .git/objets/pack/pack-49*.pack \
.git/objets/pack/pack-49*.idx .
git unpack-objects <pack-49*.pack

I haven't tested these corner cases extensively yet, but from reading
the code it should behave like this:
If you have loops or multiple references to the same repository then
only the first occurance is used. When reading a reference to an alternate
object store for the second time it is simply ignored.
But of course you should be careful when you set up alternate files.
Having two repositories reference each other and then simultanously
running git-prune in both is obviously not a good idea ;-).
... more testing ...
Well of course practice and reality always differ... I'll send an
updated patch shortly ;-)

From: Josh Boyer @ 2006-05-01 22:52 UTC (permalink / raw)

I was playing around with git repack and decided to "undo" the repack
I did using git-unpack objects. Below is the output:
[jwboyer@vader linux-2.6]$ git-unpack-objects <
.git/objects/pack/pack-497d1e639572013de48eeb00cb95738d2ca959e1.pack

drwxrwxr-x 2 jwboyer jwboyer 4096 May 1 17:48 pack
[jwboyer@vader linux-2.6]$
As you can see, the objects don't seem to get unpacked back into the
.git directory. So either I am misunderstanding what that command is
supposed to do, or it isn't working properly.
Any ideas?

OK, I replaced the eclipse file (yoda) with the latest from the head.
Then I changed it in my git project, committed it, and pushed it to the
shared repo. Finally, I did a "compare with latest from head" and it
proceeded to update the file and then said that there were no changes.

Happy. Sometimes it pays off to leave things that can be
improved as they are, mention just "we might want to do this
instead", and forget about it myself. Somebody else comes in
and fixes it for me ;-).
If you have a local copy of Linus, Jeff and David trees, you
could arrange Jeff tree to borrow from Linus and David, and
David tree to borrow from Linus and Jeff. I wonder what the new
code does when you add a new repository that borrows from Jeff
and David. Does it borrow from Linus twice? Four times? Does
it stop without falling into endless recursion? I did not do
this myself because I was lazy and did not want to address these
issues.

Hmmm. Eclipse does some weird funky sh*t sometimes. Can you ask it to
get you a log? There's an option in Eclipse CVS control settings that
will enable logging of cvs commands to the console. Enable it, and
then start Eclipse from the commandline, piping stderr and stdout to a
logfile.
There are also some weird differences depending on how you ask for the
update or diff. I hate doing this but I'll have to ask you to tell me
exactly how you ask for the diff and for the update.
And the platform you are running Eclipse on.

This tweaks the pathspec wildcard used in builtin-grep to match
that of ls-files. With this:
git grep -e DEBUG -- '*/Kconfig*'
would work like the shell script version, and you could even do:
git grep -e DEBUG --cached -- '*/Kconfig*' ;# from index
git grep -e DEBUG v2.6.12 -- '*/Kconfig*' ;# from rev

* cvsserver problem with eclipse?

[taking this conversation to the list]
OK, I changed the way I was testing this to match your usage plan and I
still got the same results. It works just fine for vanilla CVS; cvs
status shows the re revision in the repo and cvs update brings it in.
Eclipse has the same funky behavior: Compare with latest at the project
level shows no differences, but compare with latest on the changed file
actually does an update instead of popping up the Eclipse diff viewer.
By the way, I had trouble at first accessing the repo with SSH because
of permissions on the sqlite db. I'm not totally sure about the
implications for multiple users, but maybe just using a common group
will work fine?
I'm really happy with git and git-cvsserver! I'm hoping to be able to
standardize on it for our Eclipse work. It seems like it should be
possible for us to continue to do integrations in Eclipse if we manage
git properly. I've been waiting on arch, baz, and bzr for so long and
then suddenly, Linus pulls this out of his butt!

Hi Bill,
the git repo you are using, did you set it up to just be a "naked" or
"bare" repo, and enabled cvsserver alright? What version of git are you
using?
My usage plan would be to
1 - Have a git test project
2 - Publish it to a naked/bare repository where git-cvsserver is enabled
3 - Get the cvs checkout (try commandline cvs to make sure things work)
4 - Add commits in the git test project and push them to the repo
5 - Run cvs update
If it's running ok with old school CVS client, then try with Eclipse. We
have tested the update scenario quite a bit, and it works for us, so we
need a bit more info.
BTW, can I ask you to bounce these questions off the git@vger.kernel.org
<mailto:git@vger.kernel.org>
mailing list? We will be happier answering these questions in a way that
gets archived publicly. (Unless you are a direct client of Catalyst IT,
that is! Are you at OpenUniversity perhaps?)
cheers,
martin

* Re: [PATCH] built-in "git grep" (git grip).

Indeed. I was a bit confused about your report, since not only does it
work today, that's how it has always worked, and it was very much designed
that way. I use it all the time.
It takes the git-ls-files pathname syntax, which is a bit _different_ from
the normal "limit to these paths" syntax, in that it honors '*'. And it
honors that a bit differently than normal shell pathname expansion,
because for git-ls-files a '*' pattern will match '/' as well.
So
git grep pattern 'net/*.c'
will match every single C file found _recursively_ inside the "net/"
subdirectory, not just in that single directory itself.
So "*" for git grep is a bit more like a "**" pattern in some shells.

Seems I have confused myself.
git grep DEBUG '*/Kconfig*'
does indeed work today. And browsing the git grip code that
will also support it.
Sorry for the noise.

Which is indeed studip. I just learned I could say:

A feature I have been missing often has been the possibility to limit
grep (and ls-files) to certain filenames.
Say:
git grip -e DEBUG 'Kconfig*'
I usually do something stupid like:
git ls-files | grep Kconfig | xargs grep DEBUG
Thought it may be trivial to extend git grip while you are there anyway.
But obviously only if this is useful for more than just me.

* [PATCH] repack: honor -d even when no new pack was created
From: Martin Waitz @ 2006-05-01 10:57 UTC (permalink / raw)
To: git
If all objects are reachable via an alternate object store then we
still have to remove all obsolete local packs.
Signed-off-by: Martin Waitz <tali@admingilde.org>

Without this patch I got the following behaviour:
".git/objects/info/alternates" [Neu] 1L, 38C geschrieben

Done counting 0 objects.
Nothing new to pack.

After changing git-repack, objects/pack was empty, as expected.
