Switching to the GitLab bug tracker

[Thomas Huth]

 Hi everybody!

As you might have already noticed by some other mails on the qemu-devel 
mailing list, we are in progress of switching our bug tracking tool from 
Launchpad to Gitlab. The new tracker can now be found here:

 https://gitlab.com/qemu-project/qemu/-/issues

Please note that this has some implications:

1) We likely won't have the possibility anymore to automatically send e-mail 
notifications for new bugs to the qemu-devel mailing list. If you want to 
get informed about new bugs, please use the notification mechanism from 
Gitlab instead. That means, log into your gitlab account, browse to

 https://gitlab.com/qemu-project/qemu

and click on the bell icon at the top of the page to manage your 
notifications, e.g. enable notifications for "New issues" there.

2) It should be possible for everybody who has a Gitlab account to open new 
bugs. If you are a maintainer of one of the QEMU subsystems, you might want 
to help with changing certain aspects of bug tickets, too, e.g. add labels 
or assign a ticket to you or somebody else. In that case you need to be 
listed as a "Reporter" in the QEMU project, so please then get in touch with 
one of the "Owners" of the project (see 
https://gitlab.com/qemu-project/qemu/-/project_members ) and ask them to add 
you as a "Reporter".

3) Gitlab has a nice mechanism for closing bugs automatically once the fix 
gets merged to the master branch. To use this feature, please mark your 
commit messages with a "Resolves: <URL-to-the-ticket>" line. See:

https://docs.gitlab.com/ee/user/project/issues/managing_issues.html#closing-issues-automatically

4) I'm in progress of automatically migrating the open bug tickets from 
Launchpad to the Gitlab tracker. If you're interested, please keep an eye on 
those tickets and tell me if you spot any oddity there - the script that I'm 
using for the migration might not be perfect yet.
