Tired of jumping through hoops trying to understand what the "simple"
mode does, I decided to reorganize it up for good so it's crystal
clear.

There are no functional changes.

Basically the simple mode pushes the current branch with the same name
on the remote.

Except... when there's no upstream branch configured with the same name.

Now the code and the documentation are clear.

This is basically the same as v1, except I removed a bunch of patches which are now part of a
different series. Also, I updated some commit messages with suggestions from Elijah Newren.

The result of this series is in short this function:

static void setup_push_simple(struct remote *remote, struct branch *branch, int triangular)
{
	if (!branch)
		die(_(message_detached_head_die), remote->name);

	if (!triangular) {
		if (!branch->merge_nr || !branch->merge || !branch->remote_name)
			die(_("The current branch %s has no upstream branch.\n"
			    "To push the current branch and set the remote as upstream, use\n"
			    "\n"
			    "    git push --set-upstream %s %s\n"),
			    branch->name,
			    remote->name,
			    branch->name);
		if (branch->merge_nr != 1)
			die(_("The current branch %s has multiple upstream branches, "
			    "refusing to push."), branch->name);

		/* Additional safety */
		if (strcmp(branch->refname, branch->merge[0]->src))
			die_push_simple(branch, remote);
	}
	refspec_appendf(&rs, "%s:%s", branch->refname, branch->refname);
}

`simple` is the most important mode so move the relevant code to its own
function to make it easier to see what it's doing.

In order to avoid doing unnecessary things and simplify it in further
patches.

The code is copied exactly as-is; no functional changes.

Simply move the code around and remove dead code. In particular the
'trivial' conditional is a no-op since that part of the code is the
!trivial leg of the conditional beforehand.

No functional changes.

There's a safety check to make sure branch->refname is not different
from branch->merge[0]->src, otherwise we die().

Therefore we always push to branch->refname.

Now that the code has been simplified and it's clear what it's
actually doing, update the documentation to reflect that.

Namely; the simple mode only barfs when working on a centralized
workflow, and there's no configured upstream branch with the same name.

This patch series is the new second part of [1].

It borrows a few patches from v1, but it's mostly a ton of cleanups.

In theory there should be no functional changes.

There's too many changes to list them all, it's much easier to see the result:


static const char *get_upstream_ref(struct branch *branch, const char *remote_name)
{
	if (!branch->merge_nr || !branch->merge || !branch->remote_name)
		die(_("The current branch %s has no upstream branch.\n"
		    "To push the current branch and set the remote as upstream, use\n"
		    "\n"
		    "    git push --set-upstream %s %s\n"),
		    branch->name,
		    remote_name,
		    branch->name);
	if (branch->merge_nr != 1)
		die(_("The current branch %s has multiple upstream branches, "
		    "refusing to push."), branch->name);

	return branch->merge[0]->src;
}

static void setup_default_push_refspecs(struct remote *remote)
{
	struct branch *branch;
	const char *dst;
	int same_remote;

	switch (push_default) {
	case PUSH_DEFAULT_MATCHING:
		refspec_append(&rs, ":");
		return;

	case PUSH_DEFAULT_NOTHING:
		die(_("You didn't specify any refspecs to push, and "
		    "push.default is \"nothing\"."));
		return;
	default:
	}

	branch = branch_get(NULL);
	if (!branch)
		die(_(message_detached_head_die), remote->name);

	dst = branch->refname;
	same_remote = !strcmp(remote->name, remote_for_branch(branch, NULL));

	switch (push_default) {
	default:
	case PUSH_DEFAULT_UNSPECIFIED:
	case PUSH_DEFAULT_SIMPLE:
		if (!same_remote)
			break;
		if (strcmp(branch->refname, get_upstream_ref(branch, remote->name)))
			die_push_simple(branch, remote);
		break;

	case PUSH_DEFAULT_UPSTREAM:
		if (!same_remote)
			die(_("You are pushing to remote '%s', which is not the upstream of\n"
			      "your current branch '%s', without telling me what to push\n"
			      "to update which remote branch."),
			    remote->name, branch->name);
		dst = get_upstream_ref(branch, remote->name);
		break;

	case PUSH_DEFAULT_CURRENT:
		break;
	}

	refspec_appendf(&rs, "%s:%s", branch->refname, dst);
}

This code is duplicated among multiple functions.

No functional changes.

There's no need to break when nothing else will be executed.

Will help next patches.

We want all the cases that don't do anything with a branch first, and
then the rest.

Will help further patches.

All of the setup_push_* functions are appending a refspec. Do this only
once in the parent function.

Their code is much simpler now and can move into the parent function.

Only override dst on the odd case.

This allows a preemptive break on the `simple` case.

If fetch_remote is NULL (i.e. the branch remote is invalid), then it
can't possibly be same as remote, which can't be NULL.

The check is redundant, and so is the extra variable.

We want to check if remote is the same as the branch remote, not the
other way around.

It's a single line that is used in a single place, and the variable has
the same name as the function.

The typical case is what git was designed for: distributed remotes.

It's only the atypical case--fetching and pushing to the same
remote--that we need to keep an eye on.

Not your problem, but I do note, as a general point, that we don't
explain the different variants of Triangular workflow anywhere [just two
mentions in gitrevisions.txt] (e.g. patch flow versus server-side
merges, etc.).

I'd find the end-state even more readable if this "triangular" wasn't
passed as a parameter but we just did the top-level dispatch based on
that, i.e. "simple" is really internally SIMPLE_SIMPLE and
SIMPLE_TRIANGULAR, why not dispatch on that? Our internal enum doesn't
need to 1=1 map to the config setting.

Part of that's that I prefer reading code in the current "master" which
is if -> die -> most of the rest of function, v.s. your end-state of if
-> stuff -> else -> most of the function being indented to that "else".

Yes, but where are you going to make sure you are in SIMPLE, and not in
CURRENT? Surely you are not suggesting to modify
git_default_push_config(), which is pretty straightforward. So we would
need yet another enum.

I don't think there's a need for that, as you can see on the patch
series on top of this, there's not even a need to dispatch anything.

I prefer that as well, but unfortunately in this case we need to do
something after the checks to die(). I could add a goto, but for just
one conditional seems like it's not worth it.

Either way this is a temporary thing, because in the next patch series
the code becomes pretty quickly:

  if (!triangular && strcmp(branch->refname, get_upstream_ref(branch, remote->name)))
          die_push_simple(branch, remote);

And then:

  if (triangular)
    break;
  if (strcmp(branch->refname, get_upstream_ref(branch, remote->name)))
    die_push_simple(branch, remote);

Cheers.

All my documentation improvements get stuck in tar, so somebody else
would need to do that.

If and when they do, it will become clear the big pit in functionality
there is.

I'd like to remark that I personally find the following description of 
`push.default=simple`, taken from the git push man page [1], easier to 
understand:

> The current branch is pushed to the corresponding upstream branch, but
> as a safety measure, the push is aborted if the upstream branch does not

Except that isn't accurate.

  git clone $url
  git checkout -b fix-1
  # do commits
  git push

Does that push the current branch to the corresponding upstream branch?

The change and the above description makes sense to me.

I didn't, and still don't, understand the use of verb "to hedge" in
the title, though.  Apparently it isn't "to evade the risk of
commitment", "to protect oneself finantially", and of course not "to
plant, form, or trim a hedge".

> Reviewed-by: Elijah Newren <newren@gmail.com>

I trust Elijah would complain and/or clarify if this footer is
inappropriate (I didn't see an explicit "You can have my
Reviewed-by", but only "this looks good to me", and didn't know
what he meant).

I do like the change of the phrasing from triangular to same-remote
at the end of the extended series, by the way.  It makes the code
simpler to read and much easier to reason about, and it would be
nice to have it even before this step ;-)

The title says "move" and I expected to see corresponding deletions,
but it seems that this (possibly temporarily) duplicates what these
two functions do, without removing them, which (possibly
temporarily) risks the two to drift apart.  So, the resulting code
from this step will do nothing wrong (it's just two function's
bodies inlined in duplicated form), but depending on how the code
evolves, it might turn out to be a good change or a bad change---we
cannot judge by this step alone.

From a quick scanning of the remainder of the series, it seems that
3/6 and 4/6 improve the copied code without changing the behaviour,
and at the end these two functions remain, so we have duplicated
logic for these two functions and improvements only live in one of
the copies (namely, in the setup_push_simple())?  Would that be a
problem, or it is too much work to do better, I wonder?

Let's keep reading.

I suspect it would be simpler to read and easier to understand to
bring the parethesized part front, e.g.

    If you are pushing to the same repository you pull from (which
    is typically `origin`), then you need to ...

as it would avoid "the project is not centralized, but I push to my
own repository and pull from it---what should I do?" questions.

Nice.

This is not quite "reorder" but split into two.  It is not yet clear
how it helps, but hopefully we'll find out why splitting the switch
into two switches is a good idea soon in a later step, so the title
needs updating to sell that aspect of the change (unless it is a
pointless change made by mistake that the originally-single switch
got split into two, but that is unlikely the case ;-).

Not a fault of this step, but please make it a habit to have

This step is the true justification for the splitting of a single
switch into two switches done in [03/15].  Makes quite a lot of
sense.

Finally, this resolves the risk of deliberately duplicated code of
diverging, which was made in the earlier series.  Without seeing
this step, it has been dubious if the earlier change was a good one,
but with this step, it is a very clear win.

Nicely done.

This is 10/15's making, and squashing them together will make both
the entire series (because doing so means that the reviewers need to
see one fewer step) and 10/15 (because the end result of the conversion
is more "logical") easier to review (and later read in "git log -p").

I see. Then maybe reword to something like this:

In your above example, I'm in centralized workflow, but I can still push 
the fix-1 branch to origin without having to configure an upstream 
branch for it. So this seems to contradict with the currently proposed 
wording:

Those appear to be the intransitive verb definitions of Merriam-Webster
[1], there's an object in the sentence (code), so it's the transitive
ones that are applicable:

 * to enclose or protect with or as if with a dense row of shrubs or low
   trees: ENCIRCLE
 * to confine so as to prevent freedom of movement or action

Some synonyms: block, border, cage, confine, coop, corral, edge, fence,
restrict, ring, surround.

I think it fits.

But he did review the entire series. So I think it's safe to say he
reviewed this patch.

Yup.  Avoiding the phrase "centralized" and using "same_remote"
makes quite a lot of sense, too.

Overall the end-result of the series is quite pleasant read, even
though some intermediate states in the middle risked readers to
worry about "are we going in the right direction?"

Well done.

Not quite: setup_push_upstream() was simplified too, in 5/6.

Maybe I can mention that part of the code of the `simple` mode lives in
setup_push_upstream() and by copying the code to the right function both
can be simplified.

The top of `push.default says:

  Different values are well-suited for specific workflows; for instance,
  in a purely central workflow (i.e. the fetch source is equal to the
  push destination), `upstream` is probably what you want.

We already brought up the central workflow, I think it's fine to reuse
the concept below.

How about: By splitting the two kinds of modes we can return sooner in
the case the mode doesn't need to do anything else, and for the rest
that reuse quite a bit of code it can be set up after the first switch.

It is one, not the only one. But yeah, the most readily apparent.

No, you can't:

  % git push
  fatal: The current branch fix-1 has no upstream branch.
  To push the current branch and set the remote as upstream, use

      git push --set-upstream origin fix-1

Isn't that problem the one you originally described [1]?

The behavior doesn't change if you don't specify the remote:
`git push` == `git push origin`.

My wording is correct, and that's precisely the problem.

Maybe you are thinking this patch series implements the fix I proposed:
it doesn't.

The two patch series merely reorganizes the code to make it simpler and
easier to understand. No functionality changes.

It is.

Yes, I thought so. Sorry for the confusion. When I asked "will your 
provided patch fix these failing push commands" you answered "It's not 
really a patch (yet), but yeah: it will". So that's why I thought so.

My point simply is: For the sake of easiness of use, I think the 
following should work with the default settings of git:

    git clone $url
    git checkout -b fix-1
    # do commits
    git push           # should push to origin/fix-1
    # others push to origin/fix-1 (but no local changes)
    git pull           # should pull from origin/fix-1

Will this be implemented?

I have not yet sent the patch to change the current behavior.

First I sent a bunch of patches to reorganize the code so it's more
clear what it's actually doing.

Once those patches are merged, then I will probably send the one to
change the behavior.

I will include you in the Cc list when I do so.

I agree.

> Will this be implemented?

It's hard do say, but it probably won't.

All my suggestions for improvement are mostly disregarded, and
considering *nobody* has said a word about whether or not the current
behavior makes sense, I don't think there are very good chances of
changing it.

Consider my last mail "git push default doesn't make sense" [1]: nobody
replied.

But maybe that's my fault, because even though I broke the In-Reply-To
in order to start a new thread, it seems mail handling software still
uses References (incorrectly IMO).

So maybe if I start a new thread completely fresh people will notice,
and reply.

I will do so with a patch once I'm done with the reorganization.


In my experience you need to convince either Junio Hamano, or Jeff King
for any change in behavior to happen, and until they do comment on this
one it's fair to say it won't happen.

Cheers.

I assume they are on this mailing list?

I'd say it should be quite an argument if the related StackOverflow 
question dealing with this exact issue is one of the top-voted git 
questions of all time. [1]

It seems that millions of developers (judging by the number of views of 
that question) wonder what they need to do so that "git pull and git 
push will work immediately" on a newly created local branch.

If that would "just work" out of the box and with the default settings 
of git, without having to read up the solution in StackOverflow first, 
then it would certainly be an improvement for a huge number of people. 
So, to all whom it may concern, I think a behavioral change is advisable 
here.

Thank you.

Of course, and they are also on the Cc list of this mail.

That seems to be a different issue. Related, but not quite the same.

That question is answered at the time the user tries to make a push:

  fatal: The current branch fix-1 has no upstream branch.
  To push the current branch and set the remote as upstream, use

      git push --set-upstream origin fix-1

That's literally the top answer in SO.

Yes, probably many people do wonder that, but not necessarily all of
them (at least of the ones that participatd in that SO question).

I agree, but I have already tried to improve the interface in a number
of ways to no avail.

Inertia is a powerful force.

We'll see how this one goes.

Well, what the OP actually wanted to know there is "how can I use git 
pull and git push on a new local branch". The OP knows it can be done by 
configuring an upstream branch, and therefore he also specifically asks 
about the details of how to do that.

> We'll see how this one goes.

Oh, thanks for finding another instance to be corrected.  Even in
that sentence, the more important point is that upstream would be
appropriate if you push to the same place as you fetch from, and
we do not have to say "purely central" at all.

In fact there's many:

  This mode only makes sense if you are pushing to the same repository
  you would normally pull from (i.e. central workflow).

> Even in that sentence, the more important point is that upstream would

Actually, I forgot the main reason I decided to rename centralized to
same_repo: they are not the same thing.

You can have a decentralized workflow where you have multiple
repositories configured, but every branch pulls and pushes to the same
repository (to them, not other branches):

  hotfix <-> dayjob/production
  cleanups <-> upstream/master
  experiment-1 <-> personal/experiment-1

So it's more like:

  centralized = ~decentralized
  triangular = ~two-way

A centralized workflow consists of a single repository where branches
are typically two-way, but not necessarily.

A decentralized workflow consists of multiple repositories where
branches are typically triangular, but not necessarily.

So the triangularity is per branch, not per repository, and same_repo
means a two-way branch, could be a centralized or decentralized
workflow.

Therefore your proposal:

  If you are pushing to the same repository you pull from (which is
  typically `origin`), then you need to ...

is actually better, I just had to remind myself that centralized and
same repo are not the same thing.


Of course it would help to have a place in Documentation/ where
trianguar and centralized are explained.

Cheers.

My personal viewpoint is that triangular flow happens when you cannot
push to the repo you consider as upstream.

Rather you typically have a publish/backup repo instead (semi-public,
semi-private - few are interested ;-).

That (can't push one way around the triangle) part of the flow is
separate from the distinction between patch flows and merge (Pull)
request flows.

E.g. My personal Git repo can be triangular with both git.git and
git-for-windows, plus a few (what I view as) fetch-only repos from other
collaborators/maintainers beyond the triangular 'golden' upstream repo.

I often consider GitHub as a centraliser, but I don't think it's what is
being considered above.

A thought did come to mind that a Git serve/repo (typically bare) should
be able to offer a 'refs/users/*' space (c.f. refs/remotes used by
individual users) that allows a type of 'centralised' operation (almost
as if all the users used a common alternates repo). Users could only
push to their own /user refs, but could pull from the main refs/heads,
and their own refs/users/ space.

This would give flexibility to smaller corporate central operations to
offer 'triangular flow' where each dev would feel like they have their
own 'push' repo, when in reality it's really personalised branches. As
usual the authentication of user names being handed off elsewhere;-). It
could avoid some of the --alternate management aspects.

It's a thought..

It's not about permissions. Even if I had permissions to push to git.git,
I wouldn't do so. I do have permission to push to some public projects, but I
instead send patches/pull requests like everyone else.

It's more about ownership. In my personal repositories I can push
whatever I want, but on shared repositories I have to be more careful.

I think it's not separate, that is the thing that makes a triangular
flow triangular: the flow of patches goes through a different repository,
and then they get picked and merged into the upstream one.

GitHub is all about pull requests, you fork a repository, you push your
branch into that personal fork, and then you request a pull from
upstream.

That's triangular.

Yeah, and interesting thought. But it demonstrates what I said above:
you can have a central repository, and yet have triangular branches:

 feature-1 <=  origin/master
            => origin/felipec/feature-1

Yes, that is exactly why I brought up

as a reason why we want to phrase it that way, so we are on the same
page ;-)

I had it that if you don't have permissions then you definitely need to
use a Triangular flow. Hence how I was presenting the view.

True, there are social choices that are equivalent to a type of
'permission'.

Pull requests can do the same thing, just as in Git-for Windows..

I see triangular being about repos, rather than branches. The suggestion
about was, essentially, about managing multiple user forks on the same
server without using alternates etc. It's not fully thought through ;-)

If you don't have permissions you have no option but a triangular flow.

If you are in a triangular flow that doesn't necessarily mean you don't
have permissions.

If you have a feature-1 branch that fetches from origin, rebases onto
origin/master, but pushes to origin/feature-1...

Does that qualify as triangular?
