This might be simply due to a missing "GitHub Name" entry in one's b.p.o account settings. This is necessary for legal reasons before we can look at this contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

You can check yourself to see if the CLA has been received.

Thanks again for the contribution, we look forward to reviewing it!

Thanks for your PR. However, Python 3.7 has been in the security-fix-only phase of its life cycle for over a year now so, unless it can be shown that this problem is security-related, it would not meet the criteria for a security-fix-only release.

[faucct]

Can't this be merged now, but released whenever some security problem pops? This is not urgent for us, but we would like this to be fixed eventually.

[ned-deily]

Sorry, I should have been clearer. Unless it is a security-related issue, it would not be a candidate to be merged into 3.7 at all, not just released.

[ned-deily]

Since this does not seem to be a security issue for 3.7 as noted above, I am closing this PR. Sorry!
