Make a new release¶
When to tag a new release¶
Various Osmocom projects depend on others. As soon as a feature is added to one Osmocom project that is needed for another dependent project to compile, we should tag at least a minor-revision bump in the depended-upon project and require it in the depending project's configure.ac. To illustrate, let's look at this example:
Among others,openbsc
depends on the libraries built from libosmocore
, for example libosmogsm
.As soon as the
libosmogsm
library gets a new feature used by openbsc
, like something was added togsm_utils.h
, we shall
- tag a release in
libosmocore
; say if the previous version was 0.1.2, make it at least 0.1.3. - and in
openbsc
, requirelibosmogsm
>= 0.1.3 inconfigure.ac
How to tag a new release¶
The revision to tag must be merged to the public, upstream master
branch.
Find out the git hash for the revision you want to tag.
Find out the next open version number. Take care: look at all of these:git tag -l
- debian/changelog
For example, the changelog may contain versions that were forgotten to be tagged.
Now, make a GPG-signed tag of that git hash with the next open version number.
Say, for example, the git hash is 012342abcdefg
and the next open version is 0.1.3:
git tag -s 0.1.3 012342abcdefg
(If gpg
complains, see GPG: Have a matching user id.)
Verify that git picks up the new version tag:
$ git describe 0.1.3-3-g1f95179
For your local build, nothing will change until you delete the .version
file:
rm .version make cat .version
This should show the same as git describe
.
When you're convinced that all is in order, push the new tag:
git push origin 0.1.3
If anything went wrong, you can delete the tag (locally) by
git tag -d 0.1.3
and, if you've already pushed it, by
git push --delete origin 0.1.3

GPG: Have a matching user id¶
By default, git tag -s
takes your author information to lookup the secret GPG key to sign a tag with.
If the author+email do not exactly match one of the key's @uid@s, you will get this error:
gpg: signing failed: secret key not available
Verify: say, your author+email info in your git config says "John Doe <john@doe.net>", try
gpg --list-secret-keys "John Doe <john@doe.net>"
If this fails, GPG won't find the right key automatically.
Ways to resolve:
- Use
git tag -u <key-id>
- Edit your secret key to add a uid that matches your author information
gpg --edit-key john@doe.net gpg> adduid # enter details to match the git author gpg> save
