Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build.

Below you will find how the build ends (probably the most relevant part,
but not necessarily). If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202509/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:libplacebo, so that this is still
visible in the BTS web page for this package.

Thanks.

Closing FTBFS bugs when they are only fixed in experimental is misleading.

Please make an upload for unstable.

Thanks.

No, it's not. The BTS has version tracker for ages (even in Debian time
scales).

Yes, it is misleading for anybody looking at the web page and seeing
the bug at the very end of the page and closed. Not everybody uses UDD
to get bug information, there are still human beings browsing the web
pages to get information.

For ages, "open = things to do" and "closed = nothing to do".

I have yet to see why version tracking needs to change that. The tools
are there to serve its users, not the other way around.

Thanks.

If anyone opens the bug, they will see the information with versions
affected by the bug at the very top. For every other tool, where open RC
bugs make a difference (auto removal, testing migraton), also
understand version this. There is nothing gained from leaving bugs that
are only fixed in experimental open.

[ not sure why you decided to move to -devel, but anyway ]

Nothing gained? Visibility. You admit that the end user using the web
interface still needs to open the bug in the browser to see the
versions affected, and only then the end user would realize that there
is *still* work to do.

But this would not happen if we didn't gratuitously close the bug and
respected the traditional semantics:

open = still work to do
closed = nothing more to do

Version tracking was supposed to help people, not to make their work
more painful or to force them to jump through hoops.

But it's your package anyway, and I will respect your right to keep
the bug closed if it makes you happy. I'm just stating that as
a user of the BTS web pages, it's misleading and unhelpful to me.

Thanks.

Version tracking is helping here. The bug is still open in unstable and
forky. The BTS exactly tells you that. Please stop making everything
more complicated than it needs to be.
#1114180#45
Date:
2025-09-06 14:49:50 UTC
From:
To:
No, the bug is closed. There no such thing as "open in unstable".

AFAIK, the right terminology for this is to say that the bug *affects*
unstable, but there is only one open and closed thing, and it's
orthogonal to version tracking and (in this case) it's being used in
an unhelpful way.

Exactly my point. By making the traditional open/close semantics
meaningless when such thing is not strictly required by version
tracking, you are making my work as QA tester more complicated than it
needs to be.

On the other hand, if you think this open/closed thing really makes
things more complicated than they need to be, you should probably
advocate for removing such feature from the BTS completely. I'm all
for simplifying things...

Thanks.
