PSA: Please check that your Python 2 package doesn't have dependent packages before dropping it

[Randy Barlow]

Greetings!

I've been bitten twice in the past week by dependencies of my packages
dropping the Python 2 RPMs, presumably due to the Fedora 30 change[0].

Note that the change does state that the package should not be dropped
if other packages depend on them.

On that note, I do know how to check if other packages Require my
package:

$ dnf repoquery --whatrequires <something_my_package_provides>

How do I check if other packages BuildRequire my package? There doesn't
seem to be a --whatbuildrequires option on dnf's repoquery.

`dnf repoquery --enablerepo=*-source --whatrequires
<something_my_package_provides>`

If you see something like that again, please report that directly to the 
package maintainer who removed it + us (me/python-devel mailing 
list/#fedora-python/...).

We do our best to avoid this kind of situation. Sometimes a maintainer 
fails to read instructions, sometimes we screw up.

What were the packages that bit you? Do we need to fix them or was this 
taken care of already?

Be sure to check rawhide:

$ dnf --repo=rawhide repoquery --whatrequires xxxx

$ dnf --repo=rawhide-source repoquery --whatrequires xxxx

This is another reminder not to drop Python 2 packages if something 
(build)requires them.

Here is what you can use to check it:

$ dnf repoquery --repo=rawhide --repo=rawhide-source --whatrequires 
python2-freezegun

Thanks.
