[Bug 2120329] Re: MIR: libyang (previously known as src:libyang2 and src:libyang3)
** Description changed:
[Availability]
This is an MIR for src:libyang, which is a rename of src:libyang3, which also existed as src:libyang2 which had an MIR already in LP: #1958293
It's still the same project:
$ grep ^Homepage libyang2/debian/control libyang3/debian/control
libyang/debian/control
libyang2/debian/control:Homepage: https://github.com/CESNET/libyang
libyang3/debian/control:Homepage: https://github.com/CESNET/libyang
libyang/debian/control:Homepage: https://github.com/CESNET/libyang
Also look at the upstream releases:
https://github.com/CESNET/libyang/releases
We can still see it's a continuous release stream from version 2 to
version 3.
src:libyang3 was renamed to src:libyang here:
https://git.launchpad.net/ubuntu/+source/libyang/diff/debian/changelog?id=50985c9788dc3c613aab2b8efaa432f1408cd992
Ubuntu no longer has src:libyang3, and this is the situation in
questing:
$ rmadison -asource libyang libyang2 libyang3 | grep questing
libyang | 3.12.2-1 | questing/universe | source
libyang2 | 2.1.148-0.2 | questing | source
The only package depending on libyang2 is src:frr, and it can build with
libyang(3), as demonstrated in
https://launchpad.net/~ahasenack/+archive/ubuntu/frr-yang3/+packages.
autopkgtests are also green there:

Reverse-Depends
===============
* frr
* libyang2-dev
* libyang2-tools
Packages without architectures listed are reverse-dependencies in:
amd64, arm64, armhf, ppc64el, riscv64, s390x
The package libyang is already in Ubuntu universe.
The package libyang builds for the architectures it is designed to work on.
It currently builds and works for architectures: amd64 arm64 armhf ppc64el riscv64 s390x
Link to package https://launchpad.net/ubuntu/+source/libyang
[Rationale]
The package src:libyang is required in Ubuntu main for src:frr. The src:frr package can still be built with src:libyang2, but maybe that will change in the future. Thinking ahead for the next ubuntu LTS, it makes sense to start using src:libyang (version 3) now.
+ Also, src:libyang2 is gone from debian (it only exists in oldstable at
+ the moment).
+
The MIR for libyang major version 2, when it was called src:libyang2, is
at LP: #1958293.
Following advice from "Additional notes" in https://canonical-ubuntu-
project.readthedocs-hosted.com/MIR/mir-roles-and-steps/#additional-
notes, I'm not completing the remaining of the MIR template.
Regarding autopkgtests, I see that the existing tests from src:libyang2
were not copied or adapted to src:libyang.
I copied the tests from src:libyang2, adjusted the package name, and
they pass in src:libyang (v3):
autopkgtest [17:48:40]: @@@@@@@@@@@@@@@@@@@@ summary
yanglint PASS
yangre PASS
I can commit to doing that to src:libyang in the archive, and sending it
to debian.
Let me know if you need something else.
