860038 - investigate moving git tags

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[Aki Sasaki (not active)]

The issue here is that we explicitly choose to move hg tags on a regular recurring basis, and git attempts to make moving tags as difficult as possible.

https://www.kernel.org/pub/software/scm/git/docs/git-tag.html#_on_re_tagging

We need to either figure out a solution as to how to move git tags, or make that explicitly out of scope for the converted repos.

I:

* created a dev repo

git init dev

* created a ror repo

git init --bare ror/.git

* added a file to dev/ and committed

cd dev
vi plan
git add plan
git commit

* tagged

git tag tag1

* edited file

vi plan
git add plan
git commit

* pushed to ror

git push ../ror/.git master tag1

* mirrored ror

cd ..
git clone ror rem1

* verified tags:

git --git-dir dev show tag1
git --git-dir ror/.git show tag1
git --git-dir rem1 show tag1

(all the same)

* moved tag

cd dev
git tag -f tag1
git show tag1  # tag moved!

* pushed tag

git push ../ror/.git tag1
git --git-dir ../ror/.git show tag1  # tag moved!

* pulled tag in rem1

cd ../rem1
# try various permutations of |git pull| and |git fetch| without actually succeeding (tag doesn't move), then:
git pull -t
# note that git suggests |git fetch --tags|
git show tag1  # tag moved!
