Dear maintainer:

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

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

https://people.debian.org/~sanvila/build-logs/202605/

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 cannot 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:python-memray, so that this is still visible in the BTS web page for this package.

Thanks.

Thanks for this patch. However, the package's git repository already had an update to the new upstream version 1.9.1, which contains a very similar patch (https://github.com/bloomberg/memray/commit/26b7f3b457943fba5c3fa36cae3102174ff0ceea).
That update had a finalized changelog but for some unclear reason hadn't actually been uploaded to unstable. I think at this point it likely makes more sense to base work on a current upstream version, so I've upgraded further to 1.9.3 and uploaded that.

Description: Fix compatibility with Textual 8. Textual 8 renamed the Widget.renderable attribute to Widget.content. The render_widget helper in the test suite used renderable, causing test failures with Textual 8. This patch adds a fallback: first tries renderable (for backward compat), then falls back to content. . The helper is only used in tests. Forwarded: https://bugs.debian.org/1135455

For future reference, https://dep-team.pages.debian.net/deps/dep3/ makes it clear that the Forwarded field should be about the patch having been forwarded from Debian to upstream, not from you to Debian. Bug-Debian is the proper field to use to point to the Debian bug.

Thanks,
