I kind of like this part.
I also like the part that stops mentioning the "pretend fetching
back" action. This would mostly parrot the same set of refs for
people who do use the tracking branches anyway.

Here's a possible cleanup patch. It's on top of the enhanced
--early-output format commit, and in fact fixes a stupid bug in that
commit ("return -1" vs "return NULL"), but that bug-fix is really an
independent thing.
It basically removes the unnecessary indirection of "revs->prune_fn",
since that function is always the same one (or NULL), and there is in fact
not even an abstraction reason to make it a function (ie its not called
from some other file and doesn't allow us to keep the function itself
static or anything like that).
It then just replaces it with a bit that says "prune or not", and if not
pruning, every commit gets TREECHANGE.
That in turn means that
- if (!revs->prune_fn || (flags & TREECHANGE))
- if (revs->prune_fn && !(flags & TREECHANGE))
just become
- if (flags & TREECHANGE)
- if (!(flags & TREECHANGE))
respectively.
Together with adding the "single_parent()" helper function, the "complex"
conditional now becomes
if (!(flags & TREECHANGE) && rev->dense && single_parent(commit))
continue;
Anyway, do with this as you will. I think it's ok, but apart from passing
the test-suite and looking obvious, this has gotten zero testing.

.. and this extends a bit further on the notion.
It basically means that "rev->dense" can now be ignored outside of
revision.c, because we'll just set TREECHANGE automatically when
seeing a non-merge regular commit when --sparse is being used.
So it's not just a simplification, it's a performance optimization too!
Although since nobody sane would ever use --sparse, I guess nobody really
cares.

Gaah, and thanks.
We really should have "negative" tests to catch this kind of
breakage in our testsuite. People when inventing new features
are eager to write tests to show off the new stuff works, but
not many people are careful enough to add tests to demonstrate
the commands properly catch user errors such as borked command
line options.

that the right process failed.

That's an odd combination of behavior: we update some of the refs, leave
the ones that didn't work alone, report success on the ones that worked,
but then we forget that some things worked?
If we're going to refuse to update local tracking refs, whose state
doesn't matter much, we should certainly refuse to update the remote refs,
which are probably public and extremely important. If we just pushed and
we fetch, we should see exclusively changes that somebody else (including
hooks remotely) did, not anything that we ourselves did.

I'd guess -2 is supposed to indicate that there were some errors but some
things may have worked. If pack_objects() or receive_status() fails, we
shouldn't update anything locally (because it won't have been accepted
remotely); otherwise, we should make local updates of every remote efect
we had, even if we end up returning non-zero to indicate that we didn't do
everything asked.

* git pull opinion
From: Aghiles @ 2007-11-05 21:52 UTC (permalink / raw)
To: git
Hello,
I am not sure this is the best place to write about this. Anyway,
we just switched a couple of repositories to git (from svn) here
at work and one thing people find annoying is a pull into
a dirty directory. Before the "stash" feature it was even worse
but now we can type:
git stash
git pull
git stash apply
But isn't that something we should be able to specify to the "pull"
command ? Additionally and if I am not mistakn, those commands will
create "dangling" commits and blobs. So one has to execute:
git prune
Is there an "easier" way to pull into a dirty directory ? I am
asking this to make sure I understand the problem and not
because I find it annoying to type those 4 commands to perform
a pull (although some of my colleagues do find that annoying :).
For now, I am recommanding to my colleagues to commit very often
(even unfinished changes), pull, and then rebase the commits into
a more meaningful commit before pushing. Which seems to be a good
practice anyway,
Thank you for git,
- Aghiles.
ps; if someone is interested to hear what is the general opinion
on switching to git from svn in our company, I could elaborate.

I think that would just add to confusion. "revert" applies to full
changesets, not single files, plus it creates a new commit, which is
probably not what the user wants. Most of them just want to revert some
local changes to some random files, so teach them what they need, if
anything.

This is a different case: you're basically performing the same
operation, with the second line applying just to a subset of files.

Huh? The first one moves HEAD. The second one doesn't.

Is it really needed to declare those variables outside of a function
in this case? This scheme makes difficult reusing the code from other
builtins, rewriting it for libification, calling it many times, or
even understand if they were declared that way with a purpose or not.
I just don't know why they are that way in this case, is there a
reason for it?

Okay, I suppose we will end up using the big macros then. Though I had a
look at diff_opt_parse and setup_revisions, the move isn't for tomorrow.
The current code is heavy (at best), and has some logic that parseopt
is not yet ready to deal with (mainly the --not flags).

That's an example of mixed-mode UI, but what you are suggesting
is quite different, isn't it?
There is no other officially supported single-command-way to
checkout paths out of the index. "git checkout paths..." does
not introduce a confusion because of that. The user learns the
way git supports that concept and that's the end of the story.
The same thing can be said about "git checkout <commit>
paths...". That's _the_ way to checkout paths out of an
arbitrary commit.
In the case being discussed, we already have the concept of
checking out paths from the index, which has an officially
supported way to express.
You are proposing to give it a synonym "git revert paths...",
which superfitially sounds friendlier. But I actually think
allowing a mistaken
git revert path...
to be burned to users' fingers and brains is doing the user a
great disservice.
The next person would say "Why doesn't 'git revert HEAD path...'
work?", and you would add the synonym to do 'git checkout HEAD
path...'. Up to that point it is sort-of Ok (but not quite).
You already have "git checkout" that let's you do so, but you
introduced new concepts that are "revert paths to the index" and
"revert paths to the last commit".
Which may make you feel good, but you just introduced a narrower
synonym the user needs to learn, than a more established and
wider concept that we already have: "checkout paths out of X",
where X are either the index or an arbitrary commit.
The reason I think the narrower synonym is bad and will lead to
more user confusion is because after that point you will have
a few issues.
Another newcomer would say "I like the fact that 'git revert
HEAD path...' works but why doesn't 'git revert HEAD~12 path...'
work?".
- You may further allow "git revert <arbitrary-commit>
path...". But what does that _mean_? "revert the path to
the twelfth commit"? You may implement that _anyway_.
Then, the user would say "eh, why do you have both 'git
checkout path...' and 'git revert path...' that seem to do
the same thing? There's no difference? Why Why Why, git is
so hard to learn".
- You may instead not to do so, and explain that the "arbitrary
commit" form is not supported and tell the user to use "git
checkout <commit> paths...".
The user will say: "but you earlier told me to use revert --
you could have taught me to use checkout from the beginning
and saved me from great confusion instead".
Giving the same concept two different names is bad unless there
is a compelling reason to do so. Labelling an initially
narrower subset of an existing concept with a different name,
and having to extended that 'new concept' ending up with the
same as the existing concept is even worse.

To be precise: this is ambiguous only on case-challenged filesystems

While still not convinced about that "unnecessary", i had to admit the risk
of breaking something with my addition was too high. What about a compromise?
I have improved the documentation about shared repositories. A patch coming

If I remember correctly there is/was some preliminary work (at most 'pu'
stages) about adding --dirty option to git-merge, git-pull and git-rebase.

Now that I look at it again, it seems the long options look quite
inconsistent. I think it should be either
--numbered-files/--no-numbered-files or --numbered/--no-numbered. My
preference is with the latter (for brevity), but that breaks
backward-compatibility.
Would you accept a patch that changed --numbered-files to --numbered,
and kept the former as a synonym?

Next, give every team member read/write access to this repository. One
easy way to do this is to give all the team members ssh access to the
machine where the repository is hosted. If you don't want to give them a
full shell on the machine, there is a restricted shell which only allows
users to do git pushes and pulls; see gitlink:git-shell[1].
