# [PATCH] push: Alias pushurl from push rewrites 4 messages from 2013-03-17 to 2013-03-18. Participants: Rob Hoelz, Junio C Hamano. Thread: https://gitlist.dev/t/33210 ## Rob Hoelz, 2013-03-17 22:50 Subject: [PATCH] push: Alias pushurl from push rewrites Message-ID: <20130317235040.4cdc9ef2@hoelz.ro> URL: https://gitlist.dev/e/20130317235040.4cdc9ef2%40hoelz.ro ``` git push currently doesn't consider pushInsteadOf when using pushurl; this tests and fixes that. If you use pushurl with an alias that has a pushInsteadOf configuration value, Git does not take advantage of it. For example: [url "git://github.com/"] insteadOf = github: [url "git://github.com/myuser/"] insteadOf = mygithub: [url "git@github.com:myuser/"] pushInsteadOf = mygithub: [remote "origin"] url = github:organization/project pushurl = mygithub:project Signed-off-by: Rob Hoelz --- remote.c | 2 +- t/t5516-fetch-push.sh | 20 ++++++++++++++++++++ 2 files changed, 21 insertions(+), 1 deletion(-) diff --git a/remote.c b/remote.c index ca1f8f2..de7a915 100644 --- a/remote.c +++ b/remote.c @@ -465,7 +465,7 @@ static void alias_all_urls(void) if (!remotes[i]) continue; for (j = 0; j < remotes[i]->pushurl_nr; j++) { - remotes[i]->pushurl[j] = alias_url(remotes[i]->pushurl[j], &rewrites); + remotes[i]->pushurl[j] = alias_url(remotes[i]->pushurl[j], &rewrites_push); } add_pushurl_aliases = remotes[i]->pushurl_nr == 0; for (j = 0; j < remotes[i]->url_nr; j++) { diff --git a/t/t5516-fetch-push.sh b/t/t5516-fetch-push.sh index b5417cc..272e225 100755 --- a/t/t5516-fetch-push.sh +++ b/t/t5516-fetch-push.sh @@ -244,6 +244,26 @@ test_expect_success 'push with pushInsteadOf and explicit pushurl (pushInsteadOf ) ' +test_expect_success 'push with pushInsteadOf and explicit pushurl (pushInsteadOf does rewrite in this case)' ' + mk_empty && + TRASH="$(pwd)/" && + mkdir ro && + mkdir rw && + git init --bare rw/testrepo && + git config "url.file://$TRASH/ro/.insteadOf" ro: && + git config "url.file://$TRASH/rw/.pushInsteadOf" rw: && + git config remote.r.url ro:wrong && + git config remote.r.pushurl rw:testrepo && + git push r refs/heads/master:refs/remotes/origin/master && + ( + cd rw/testrepo && + r=$(git show-ref -s --verify refs/remotes/origin/master) && + test "z$r" = "z$the_commit" && + + test 1 = $(git for-each-ref refs/remotes/origin | wc -l) + ) +' + test_expect_success 'push with matching heads' ' mk_test heads/master && -- 1.8.2 ``` ## Junio C Hamano, 2013-03-17 23:35 Subject: Re: [PATCH] push: Alias pushurl from push rewrites Message-ID: <7vd2uxppk0.fsf@alter.siamese.dyndns.org> URL: https://gitlist.dev/e/7vd2uxppk0.fsf%40alter.siamese.dyndns.org In-Reply-To: <20130317235040.4cdc9ef2@hoelz.ro> ``` Rob Hoelz writes: > git push currently doesn't consider pushInsteadOf when > using pushurl; this tests and fixes that. > > If you use pushurl with an alias that has a pushInsteadOf configuration > value, Git does not take advantage of it.

Sorry; that's a good point. With the above configuration, the following fails: $ git push origin master With the following message: fatal: remote error: You can't push to git://github.com/myuser/project.git Use git@github.com:myuser/project.git So you can see that pushurl is being followed (it's not attempting to push to git://github.com/organization/project), but insteadOf values are being used as opposed to pushInsteadOf values for expanding the pushurl alias. I haven't tried without pushInsteadOf; I will add a test for it later today. I assume that if pushInsteadOf isn't found, insteadOf should be used? I will also consider the other test cases you described.
