Hi!
I don't know if this is a lack of understanding or a software or documentation bug.
man git-fetch says about tags:
By default, any tag that points into the histories being fetched is
also fetched; the effect is to fetch tags that point at branches that
you are interested in.If I fetch without --tags the tags that point to the commits of the fetched branch are not fetched. If I fetch with --tags than all tags are fetched but I only wish to fetch tags pointing to something in the branch fetched.
Here is a self contained example:
--------------------------
$ cd /tmp
$ git init r1 && cd r1
Initialized empty Git repository in /tmp/r1/.git/
$ date >f1
$ git add f1
$ git commit -minitial f1
[master (root-commit) 61753c60ac] initial
1 file changed, 1 insertion(+)
create mode 100644 f1
$ git tag -mt1 t1
$ git tag t2
$ git init ../r2 && cd ../r2
Initialized empty Git repository in /tmp/r2/.git/
$ git remote add origin $(cd ../r1; pwd)
$ git fetch origin master
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
From /tmp/r1
* branch master -> FETCH_HEAD
* [new branch] master -> origin/master
$ git tag | wc
0 0 0
$ git fetch --tags origin master
remote: Enumerating objects: 1, done.
remote: Counting objects: 100% (1/1), done.
remote: Total 1 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (1/1), done.
From /tmp/r1
* branch master -> FETCH_HEAD
* [new tag] t1 -> t1
* [new tag] t2 -> t2
$ git tag | wc
2 2 6
$ git rev-parse FETCH_HEAD
61753c60ac550a5315b7c930a701b94f36e08e4f
$ git rev-parse t1^{commit}
61753c60ac550a5315b7c930a701b94f36e08e4f
$ git rev-parse t2^{commit}
61753c60ac550a5315b7c930a701b94f36e08e4f
--------------------------Obviously the two tags point to the fetched commit but without --tags they are not fetched. The behavior is identical for lightweight and annotated tags.
