I think push should work like this: * the user gives us a nickname; * we look at remote.$nickname.pushurl (and if there isn't, remote.$nickname.url) to decide the logical URLs to push to; * for each logical URL we decided to push, we look at url.*.pushInsteadOf to see if there is one that match the $URL (and if there isn't url.*.insteadOf), and map the logical URL to the final destination. So that we can instruct "push" to push, when pushing into a repository that logically resides at git://git.k.org/pub/, to instead push into the repository via git-over-ssh, e.g. [remote "korg"] url = git://git.k.org/pub/scm/git/git.git/ [url "git.k.org:/pub/"] pushInsteadOf = git://git.k.org/pub/ without affecting the fetching side. As I said in a separate message, the above "fetch/push" vs "fetch" and "push" distinction is not descriptive enough to express the post rewriting that is done with insteadOf; it only helps debugging misconfiguration between .url vs .pushurl, which may be better than the status quo but is not ideal. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

For "set url --add --push" on top of a push url only being defaulted from a fetch url, both behaviours (replace or add, i.e. current or new) make sense to me. So the questions are: - Is it worth and possible changing? - How to best describe it in "remote -v" and "remote show" output? My patch answered to "no" to the first question and answers the second one in cases where (push)insteadof is not used to transform one fetch config into two different urls for fetch and push.

I agree with Michael that changing the set-url behavior would be appropriate here. If I say "--add" this pushUrl, don't I mean to create an additional url which is pushed to?

That is my definition of "same", in the sense of "object-and-ref-same"
when "in-sync" (at least regarding all pushed refs; there may be more
there).

I thought it was about unauthenticated git-protocol vs. git+ssh but was

Yes. That is also why we fetch from one fetch URL only, because we

Do we fall back to two if one is unavailable? In any case, people may
use a configuration like that to keep track of mirrors and shuffle
around the fetch lines (rather than commenting/uncommenting) when one
goes offline.

That is not necessarily true, depending on the definition of your
"same". Having multiple URLs/PushURLs that refer to physically
different locations, as long as "git push there" immediately
followed by "git fetch here" should work with the repositories that
are conceptually equivalent, is a supported mode of operation. In
fact, they being physically different _was_ the original motivation
of the feature. See 755225d (git builtin "push", 2006-04-29).
The definition of the "immediate" above also depends on your use; it
could be tens of minutes (you may be fetching from git.k.org that
can be reached from the general public, which may be a cname for
multiple machines mirroring a single master.k.org that k.org account
holders push to, and there may be propagation delays). In such a
scenario, your URL may point at the public git.k.org, pushURL may
point at master.k.org, and you may have other pushURLs that point at
other places you use as back-up locations (e.g. git.or.cz or
github.com).
As long as you _mean_ to maintain their contents the same, you can
call them conceptually "the same repo" and your statement becomes
true.
> It never was meant to push to several repos.
This is false. It _was_ designed to be used that way from day one.
(I am not saying using it in other ways is an abuse---I am merely
saying that pushing to multiple physically different repositories is
within its scope).
> That being said, I don't mind changing the behaviour of set-url.
I do not think we want to change the behaviour of set-url. What
needs to be fixed is the output from "remote -v". It should:
* When there is no pushURL but there is a URL, then show it as
(fetch/push), and you are done;
* When there is one or more pushURLs and a URL, then show the URL
as (fetch), and show pushURLs as (push), and you are done;
* When there are more than one URLs, and there is no pushURL, then
show the first URL as (fetch/push), and the remainder in a
notation that says it is used only for push, but it shouldn't be
the same "(push)"; the user has to be able to distinguish it from
the pushURLs in a repository that also has URLs.
* When there are more than one URLs, and there are one or more
pushURLs, then show the first URL as (fetch), the other URLs
as (unused), and the pushURLs as (push).
Strictly speaking, the last one could be a misconfiguration. If you
have:
[remote "origin"]
url = one
url = two
pushurl = three
pushurl = four
then your "git fetch" will go to one, and "git push" will go to
three and four, and two is never used.
It should also be stressed that the third one a supported
configuration. With
[remote "origin"]
url = one
url = two
your "git fetch" goes to one, and your "git push" will go to one and
two. This is the originally intended use case of 755225d. It is to
push to and fetch from master.k.org (think of "one" above) and in
addition to push to backup.github.com ("two").

Yes, that is one big source of misunderstanding. Cleaning up remote -v would help, along with the man page. Also there is a conceptual confusion: pushurl is meant to push to the same repo using a different url, e.g. something authenticated (https/ssh) for push and something faster/easier for fetch.

It is "remote -v" that is misdesigned. $ git clone ../there here $ cd here $ git remote -v origin /var/tmp/there (fetch) origin /var/tmp/there (push) This is totally bogus. It should report something like this: $ git remote -v origin /var/tmp/there (fetch/push) Then after running "git remote set-url --push origin ../another" we should see $ git remote -v origin /var/tmp/there (fetch) origin /var/tmp/another (push) which would make it clear that the original fetch/push came from the (1) usuall you push and fetch from the same place so there is only one setting, and the two lines came from the (2) sometimes you need a separate places to fetch from and push to. At this point, if you say "set-url --push origin ../third", then "another" will disappear and gets replaced by "third"; if you instead say "set-url --add --push origin ../third", then we will see two (push) lines, in addition to one (fetch), making it clear that you are still in (2) above, fetching from and pushing to different places, and having two places to push to.

I understood that the defaul push url is not used by git-push when there's at least one pushurl for a given remote. If that's by design, I still fail to comprehend the exact reason. If you allow me, I'd like you to forget about the concepts for a minute, and focus on the user experience. Imagine a simple hypothetical scenario in which the user wants to push to 2 distinct repositories. He already has cloned the repo from the 1st repository, thus (theoretically) all he needs to do, is to add a new repository for push. He then uses `remote set-url --add --push <2nd-repo>` (which I personally thought would suffice). However, if he tries to push a new commit to this remote, it would be pushed _only_ to the 2nd-repo. This is exactly what I thought to be a bug. If it's intended to work the way I described in the previous scenario, I'll have to ask and/or research to understand the reason behind this -- Why does having a pushurl make git-push _not_ to push to the default push location (the 1st repo in my scenario) as well?

That way, the operator can use plain "set-url --push" to clarify whether whether he meant to include the pull URLs in the new pushurl set.

You're right. However, as I quoted earlier, the git-remote man-page states: set-url Changes URL remote points to. With --push, push URLs are manipulated instead of fetch URLs. With --add, instead of changing some URL, new URL is added. It explicitly mentions that it should **add a new URL**. So when I do `git remote set-url --add --push origin git://another/repo.git`, I expect git-push to use both the default push URL and the new one.

Correct. Adding a remote doesn't automatically generate a pushurl for it. To me, it seems that git-push checks for the existence of pushurl's in the config, and if it finds any, it ignores the defaul push URL during the actual push. In better words, it pushes only

This question is trying to > tell if your bug is in "git remote -v" or in "git remote set-url". I'm not sure, if there is a bug at all. According to man git-push: The is used for pushes only. It is optional and defaults to . (From the section REMOTES -> Named remote in configuration file) the command: git remote add foo g...@foo-fetch.org/some.git will set "remote.foo.url" to "g...@foo-fetch.org". Subsequently, fetch and push will use g...@foo-fetch.org as url. Fetch will use this url, because "remote.foo.url" explicitly sets this. push will use it in absence of a "remote.foo.pushurl". Now, we're adding a push-url: git remote set-url --add --push foo g...@foo-push.org/some.git Relevant parts of config are now looking like: [remote "foo"] url = g...@foo-fetch.org/some.git pushurl = g...@foo-push.org/some.git Since, pushurl is now given explicitly, git push will use that one (and only that one). If we add another push-url now, git remote set-url --add --push foo g...@foo-push-also.org/some.git the next git-push will push to foo-push.org and foo-push-also.org. Now, using --set-url --delete on both of these urls restores the original state: only "remote.foo.url" is set; meaning implicitly pushurl defaults to url again. To me this is exactly what Jardel was observing: > In step 2, Git replaced the original push URL instead of adding a new > one.

Or am I missing something here? Might be that the "bug" actually is that the expectation was git remote add foo g...@foo-fetch.org/some.git should have created a config like: [remote "foo"] url = g...@foo-fetch.org/some.git pushurl = g...@foo-fetch.org/some.git since that is what "git remote -v" reports. If that is the case, we might want to amend the output of 'git remote -v' with the information that a pushurl is not explicitly given and thus defaults to url.

Re: [BUG] Possible bug in `remote set-url --add --push`
Step 1:
jweyrich@pharao:test_clone1 [* master]$ git remote -v
origin /Volumes/sandbox/test (fetch)
origin /Volumes/sandbox/test (push)
jweyrich@pharao:test_clone1 [* master]$ git config -l | grep '^remote\.origin'
remote.origin.url=/Volumes/sandbox/test
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
Step 3:
jweyrich@pharao:test_clone1 [* master]$ git remote set-url --add
--push origin /Volumes/sandbox/test_clone2
origin /Volumes/sandbox/test (fetch)
origin /Volumes/sandbox/test_clone2/ (push)
jweyrich@pharao:test_clone1 [* master]$ git config -l | grep '^remote\.origin'
remote.origin.url=/Volumes/sandbox/test
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.pushurl=/Volumes/sandbox/test_clone2/
After that, if I do a commit in test_clone1 and try to push to origin,
it pushes only to the test_clone2 rather than pushing to both test and
test_clone2 (it's a bare repo, sorry for using a misleading name).
Is `remote..pushurl` required for the primary URL as
well? If not, then git-push is not handling that information as it
should.

The original pushurl was replaced with the additional one, instead
of being left and the new one getting added. That looks certainly
wrong.
However, the result of applying the attached patch (either to
v1.7.12 or v1.8.1) still passes the test and I do not think it is
doing anything differently from what you described above.
What do you get from
git config -l | grep '^remote\.origin'
in steps 1. and 3. in your procedure? This question is trying to
tell if your bug is in "git remote -v" or in "git remote set-url".
