Description Toshio Kuratomi 2014-06-19 15:29:50 UTC
Description of problem:

2to3 is provided by upstream python to aid in porting code from python2 to python3.  It finds common code patterns that have changed and updates them to the new pattern.  This tool is shipped with the upstream python tarball and so it is only updated when the python interpreter and stdlib has a new release.

Now that python2 is entering maintainance mode, python3 will see more frequent updates than python2.  This will allow mean that the 2to3 in python3 will quickly get ahead of the python2 version.  We should therefore switch /usr/bin/2to3 from being the python2 provided version to being the python3 provided version.  A version of 2to3 under a different name should remain for people who still want to use the python2 version on their systems (for debugging or to eliminate deps on certain systems).

Comment 5 Fedora End Of Life 2016-07-19 11:49:23 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 6 Petr Viktorin (pviktori) 2016-07-29 10:17:37 UTC
Still valid.

Comment 7 Miro Hrončok 2017-08-16 13:43:42 UTC
Removed from python2-tools and added to python3-tools. Proper conflicts added.

2to3-X.Y shoudl also be removed from python26 and python3{3..6}.

As per the original request:

> A version of 2to3 under a different name should remain for people who still want to use the python2 version on their systems (for debugging or to eliminate deps on certain systems).

    $ python2 -m lib2to3

can be used instead.

Comment 8 Miro Hrončok 2017-08-31 11:52:25 UTC
Requested a guideline change, because 2to3 is explicitly mentioned there and what I did goes against that guideline (however weird that guideline is).
