Hello,
I have a repository with following situation:
$ git describe next
v4.1-2196-g5a414d7
$ git describe next --match=v4.2
v4.2-4757-g5a414d7
Since the tag with fewest commits since is selected, it appears logical.
However, v4.2 is descendant of v4.1, so it does not make sense for it to have
more commits since. And rev-list or log confirm that:
$ git rev-list v4.1..next | wc -l
2196
$ git rev-list v4.2..next | wc -l
1152
The number of commits since v4.1 matches what the describe counted, but the
number of commits since v4.2 does not.
The v4.1 tag should be reachable along the first parent path, the v4.2
definitely isn't, but I am not asking for first parent path.
I am using
$ git --version
git version 2.7.0
from Debian git 1:2.7.0-1 package locally, but our build server is still using
rather ancient
$ git --version
git version 1.8.4.msysgit.0
with exactly the same result.
Unfortunately I can't share the repository, but I could run some tests on it,
including rebuilding git with some diagnostics and trying that.
Note that the tag v4.2 is otherwise perfectly good candidate for describe and
gets used just fine when describing master:
$ git describe master
v4.2-2-g34eb80b
$ git describe master --match=v4.1
v4.1-1046-g34eb80b
However when I merged master into next, it started producing those incorrect
results.
