Git tags

Git tags

[Oliver Beattie]

Hi,

I have noticed that when a new snapshot is released, it is tagged in
the Git repository, and an old tag is typically removed. While I
understand Wireguard is considered experimental, this is quite
frustrating as a user of the project.

Given tags in Git are extremely lightweight, would it be unreasonable
to keep them around?

Cheers,
Oliver

Huh, i hadn't noticed that older tags had been removed in the canonical
upstream git repo, i agree that's unusual and rather strange.

The repository where i record debian packaging changes includes a full
copy of the upstream repo (at least as far as what's been packaged) and
that naturally includes the older tags as well:

    https://anonscm.debian.org/git/collab-maint/wireguard.git/refs/tags

You're always welcome to pull the tags from there (the upstream takgs
should all be cryptographically signed by Jason, so you can verify
authenticity even if the network source is different).

I can keep them around, no problem. I just thought they looked sort of
cluttered, so I removed them, but if it's useful to you, I don't mind
keeping them.

What use case did you have in mind, anyway, for old tags?

Hi Jason
I usually find it useful when I'm provisioning with ansible to be able to
point to a tag and upgrade when I'm ready, so when I provision new nodes
they all have the same version, even if a new version is out.

Never use old snapshots.

But the problem is that if I have 20 nodes and need to add some more and
there is a breaking change like there was recently with the psk changing to
peers instead of interface I can't always do that change before I need to
add a new node.
Would just be nice if the tags hung around for maybe a year.

How many times has this affected you? "Once", I assume. Breaking
changes certainly aren't the norm, and I'm sorry that it happened at
all and you have to deal with it. Big hassle. I don't want to subject
folks to that again if I don't have to. It still _may_ happen, but I
hope it won't, and we're working steadily toward the goal of
stabilizing.

> Would just be nice if the tags hung around for maybe a year.

This is currently experimental software. Someday it won't be
experimental, but today it is. You should not use old snapshots,
period. I'd strongly advise you to update all your nodes.

(However, I'll keep old tags around, because Oliver asked, and my only
reason for actually removing the tags was I thought cgit looked
prettier without the clutter, which isn't a good reason for anything.)

Many thanks, that's really helpful :-)

Often the only record I will keep of the version I've built/am running
is the tag name. Of course this means my process is deficient, I just
thought that there was little downside to keeping them around.

Because --branch <name> means get refs/heads/<name>, tags are not
branches. However, because we're apparently quite loose about this in
the clone/fetch code this does give you the tag if it exists, but
probably not in the way you expect.

We interpret the argument as a branch, and will get not only this tag
but "follow" (see --no-tags in git-fetch(1)) the tag as though it were a
branch and give you all tags leading up to that one. This would give you
a single tag:

    git clone --no-tags --branch v2.19.0 --single-branch https://github.com/git/git.git

But this is a more direct way to do it:

    git init git; git -C git fetch --no-tags https://github.com/git/git.git tag v2.19.0

Which'll since you said it failed that's because you haven't pushed the
tag. Try 'git ls-remote <url>' to see if it's there (it's not).

After my yesterday experience [1], I'd be careful with git push --tags :)

git push --tags

and

git fetch --tags

to be symmetrical

From https://git-scm.com/book/en/v2/Git-Basics-Tagging
"By default, the git push command doesn’t transfer tags to remote servers.
You will have to explicitly push tags to a shared server after you
have created them."

[Stefanie Leisestreichler]

Hi.

I have done this (on box A):

git commit -m "Message"
git tag -a 0.9.0
git push origin master

In my local repository, when I run "git tag" it is showing me "0.9.0".

Then I did (on box B)
git clone ssh://user@host:/path/project.git
cd project
git tag

Now git tag is showing nothing.

Why is the tag only available in my local repository?

Also when I try to
git clone --branch 0.9.0 ssh://user@host:/path/project.git
it tells me: fatal:remote branch not found in upstream repository origin

Why is the tag not available in origin?

Thanks,
Stefanie

You'll need to push the tags out to your repo on k.org too...

Hi Ben,

Could you please pull the git tags from Linus' tree when you pull?

It aids a little in quickly seeing how far a tree on kernel has moved
forward, at the moment the last tag on your tree is "v2.6.26-rc9" [1].

Hi all,

I don't really know where to post this question. Why, if I check out the 
2.6.24.4 kernel (2.6.24.4 tag 
http://git2.kernel.org/?p=linux/kernel/git/stable/linux-2.6-stable.git;a=commit;h=16c64cac7d9c6a503f49887219c4fe675e7d43d9) 
from the stable git tree, I get "dirty" added to my kernel version after 
compilation? The 2.6.24.4 is stable as far as I understand.
I have already searched for this info and looked through some tutorials 
like http://linux.yyz.us/git-howto.html, but I didn't find any info that 
would answer my question.

Thank you  in advance.

Sorry, sometimes I forget to do git-pull --tags from the mainline tree.
I'll update the tags in linux-omap tree shortly.

True. You need to do "git fetch tags" for upstream. Looks like Tony
had not fetched tags from kernel.org.

If you are not messing with your master branch then it will also point
you the latest pulled commit and ofcourse date for that commit.

[Iqbal]

Hi, 

I see that the kernel is advanced from 2.6.23-rc8 to 2.6.23. 
When I do a git-tag -l, at the end I can only see 2.6.23-rc4 and not 2.6.23 or any tags between these two.

So, what I understand is "this list doesn't mess up with the tags", the tags are coming from Linus/kernel.org. 
And, there is no hard fast rule that tags are always updated.

Pl. correct me If I my understanding is wrong.

Also,

How can I get the date when I did the last git-pull/git-fetch?
If there are any good pointers on versioning please pass it on.

Thanks, 
Iqbal
