No, the point is exactly to let execvp() do all the work and we don't care
which of the paths is the "success". And I don't think that this has any
negative side effects.

So long as they're added in "success:failed:failed" order, I don't see
any issues either. Assuming we stop prepending once we find something
that works, that should be a non-issue.

Yeah, I had thought about writing a little script that would take my
project's topic branches, and then push them out into the public
repository under topics/ad/extents-testcases or
topics/tt/badblocks-cleanup. That would make it easy to find the head
of your topic, and once you find that, the base of your-topic isn't
that hard to find, since it would just be the result of "git-rev-list
topic ^master | tail -1".
One of the reasons I was thinking the above is because most of the
patches are coming into my end as emailed patch series, and I end up
tweaking them a lot as I carry them around in the topics branch. So
if other people want to see what I've done to a branch after I've done
a git rebase --interactive, it's easier if they can get access to the
individual topics branch, so they can extract out the patch series
while it's being tweaked by me (and possibly others).
This is probably because my view of git has been colored by kernel
community practices, where patches are normally perfected and get
rebased a lot (normally in a sub-maintainer or maintainer's tree)
before they get pushed to Linus, and in my mental model a topic branch
represents the maintainer's git tree in the central repository.
The extreme end of this would be the classical BitKeeper model, where
Larry McVoy once argued to me that he didn't like history to *ever* be
rewound/rewritten, since not only did this interfere with other people
trees once they had been pushed, but it causes development history to
be lost, which is always valuable. (Of course, in the end he did
write "bk fold", which squashes the last N commits into 1, mainly due
to customer pressure.) The kernel viewpoint is to rebase all the
time, because the history is so huge that we don't *want* to see the
development history of the rough drafts of features before they get
merged into mainline.

It sounds like what you are saying here is that the git.git tree takes
a viewpoint which is slightly between the extremes of the kernel model
(which does involve resolving rebasing a lot and resolving lots of
conflicts, but heh, that's not Linus's problem, that's been pushed out
to the leafs of the developer community, and besides, it strongly
encourages topics to get merged into the mainline fast), and the
classical Bitkeeper model, which says that philosophical goodness
means you should keep *all* development history once it enters the BK SCM.
With git.git, we are essentially throwing away development history
while it is in 'pu', but once a commit graduates to 'next', we do keep
the development history forever. The downside to this is that
development 'crud' can build up in next; even if all substantive
commits in 'next' end up graduating to 'master', there will still be
lots of merge commits that will only be in 'next'.
I have an emotional bias which tends to treat that excess history as
toxic waste to be avoided at all costs, but that's probably because
when you have a git tree as huge as the kernel, life is easier if the
history is kept as clean as possible.
Which I suppose is easy enough to do in the git.git model; if you
throw away the 'next' branch and then rewind it so it is forked off of
'master' all of that history essentially gets flushed. The downside
is that people maintaining topics branches which were forked against
the old 'next' will need to do some grotty work to rebase their
patches, so any attempt to rewind next would probably require the
central maintainer to give plenty of notice, and then on the flag day,
save 'next' as 'old-next' before rewinding to allow the other
developers to more easily rebase any private branches they might have.
Hmm, interesting. A lot of this is quite subtle, or at least the
impacts of different choices in the git workflow really didn't become
obvious to me until I started trying I stepped into the central
maintainer role for a project using git!

Not here. I just tried (with msysGit, of course).
Anyway, I like the other patch Scott sent much more than mine, which
offloads the work to execvp().

You know what I do not like with this proposal? The whole _point_ of this
discussion is to make git _easier_. Go ahead, try to explain to a
complete git newbie the proposed behaviour. I have a pound here which
says that there is _no_ _way_ that this newbie says "well, that's easy".
Some people may not get this, but git has a reputation of being
complicated, and my "BS" argument was, is, and will be, that we should
keep clear and simple semantics, because they are the _only_ way to battle
that reputation.

That would match my usual usage well.
Actually, I really like the way the tla (arch) "undo" and "redo"
commands work: "tla undo" is roughly equivalent to "git stash", but by
default chooses a name with an appended integer which is one greater
than the greatest existing "stash" (to use git terminology). "tla redo"
by default applies the last saved value and deletes it. So basically
push and pop. Usually, of course, you only use one level, but on the
occasions when you want more, it feels very natural.
I dunno how this would work with stash, but push/pop functionality would
be good...

Will do. I didn't include it in the patch because I need to learn more

find enough examples in the other scripts that use Git.pm.

I agree, now that you mention it. Eventually the string must be split
(parsing it left to right by word makes more sense than trying to
mutate it with regular expressions, if only because it's a lot harder
to make mistakes), but there's no reason not to split the string inside
the loop, where it would look nicer/more contained. I will make this
change.

Yes, I agree that it complicates things for the caller. I was just
copying the model found in color.c; but seeing as this is Perl
splitting into lines inside the printing function would be
straightforward.

Yes, but only for fast-forward cases. When there *are* local changes,
the user must decide when to merge those, since he/she may not be done
with them. It doesn't make sense to merge local canges on a not checked
out branch automagically, because then we end up in the very unclear
semantics that Dscho (and myself) fear.
Also, as Steffen pointed out in his mail, this will make "git pull"
largely symmetrical with "git push", which *does* update all the remote
branches, but only if the update results in a fast-forward.

I appreciate this. It's certainly going to be a much bigger win on Windows,
although git svn doesn't work (in the MinGW port) at this time because of
the old perl and the missing SVN module.

Put tests in double-quotes; otherwise, the substitutions happen before the
test begins, and not as part of the test.

You mean $sha1 here, right?

This should escape the $(...) in all the tests. Like this:
"test $type = \"\$(git cat-file -t $sha1)\""

And use single quotes without escaping the double-quotes here.

The problem with that approach is that you can only send in a single
line at a time (with the newline detached!), so it makes life harder for
the caller. E.g., there is at least one spot that uses a here-doc with
many lines; splitting that into a bunch of print_ansi_color calls would
be unnecessarily ugly.

Out of curiosity, are people really running perl < 5.6? Term::ANSIColor

Good idea. But then better name it by its purpose:

I did too, where you add a third, optional "trailer" parameter to the
function where you pass the newline if there is one (following the
style of the functions in color.c). Pasting it below.
Having said that, I think this kind of function belongs in Git.pm,
and the dependency on Term::ANSIColor should be replaced with
dependency-free code that generates the colors itself; this should be
easy because the number of possible colors is small, Git thus far
only uses a subset of the possible ANSI colors, and the C code for
doing it is already there in color.c and just needs to be translated
into Perl.
sub print_ansi_color {
my $color = shift;
my $string = shift;
my $trailer = shift;
if ($use_color) {
print Term::ANSIColor::color($color), $string,
Term::ANSIColor::color('clear');
} else {
print $string;
}
if ($trailer) {
print $trailer;
}
}

Don't bother with it right now. GIT currently does not have MinGW specific

I agree that fast-import is probably ultimately a better solution for
this, but given that git-svn currently uses the output of every command
it forks off and that fast-import doesn't seem to give the same output,
changing git-svn to use fast-import would be a fairly sweeping change
that I didn't feel comfortable making without a better understanding of
git-svn.

It doesn't currently give you the hash back. You can sort of get
to it by marking the blob then using the 'checkpoint' command to
dump the marks to a file, which you can read in. Not good.
It probably wouldn't be very difficult to give fast-import a way
to dump marks back on stdout as they are assigned. So long as the
frontend either locksteps with fast-import or is willing to monitor
it with a select/poll type of arrangement and read from stdout as
soon as its ready.
Probably a 5 line code change to fast-import. Like this. Only Git
won't recognize that object SHA-1 as its in a packfile that has
no index. You'd need to 'checkpoint' to flush the object out, or
just use all of fast-import for the processing. So yea, I guess
I can see now how its not suited to this.

You don't need to do this to avoid forks. Just use git-fast-import

I actually considered using fast-import for the whole shebang, but
decided that I don't yet understand the workings and structure of
git-svn well enough to make such a big change.
git-svn uses git-hash-object to both determine a file's hash and insert
it into the index in one go -- can fast-import do this? Or will it just
put it in the index and not give you the hash back? The latter was my
impression.
