As a pragmatic matter, I think it would be worth applying it to all active maintenance branches, as: - that dramatically reduces the deployment term for it to start being useful for troubleshooting - the SSL/TLS changes mean that some redistributed versions of Python 2.7 are starting to accumulate significant backports that aren't indicated in the nominal upstream version number, but are conveyed in the full REPL header (which has redistributor build info in it) Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

The first argument is 'encoding' and the second one is 'Py_TYPE(unicode)->tp_name'. --Berker ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Certainly add it to 3.7. I think the decision whether to add it to 3.6 and the stable releases should be up to the respective release managers. As you say, it's not a language feature, but it's still a new feature and as such it does fall within a gray area. I'd personally have no problem with adding it to 3.6 and possibly earlier stable releases, but I'm not an RM of any active releases any more. I'd say, open a bug, post the patch against the versions you want to see it applied to, go through the review process, and let the RMs decide if its worth the risk.

It is a New Feature and therefore ineligible for adding to 3.5 or 3.4. //arry/ On 10/17/2016 08:05 PM, Barry Warsaw wrote: On Oct 17, 2016, at 05:01 PM, Nick Coghlan wrote: * Inada-san would like to enable "python -VV" to print the full REPL header for improved debugging information * we don't want to mess with "-V" because external scripts may be relying on it (e.g. to figure out filenames) * "python -VV" is already permitted, but just means the same thing as "python -V" I think this is a good idea So do I. , but this is a CPython-the-implementation feature, rather than a Python-the-language feature, so it isn't clear what rules apply to adding it.

I'm open to adding this feature to 3.6.0b3 but first we need an issue and a final patch to review. ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
