Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept this contribution by verifying everyone involved has signed the PSF contributor agreement (CLA).

Recognized GitHub username

We couldn't find a bugs.python.org (b.p.o) account corresponding to the following GitHub usernames:

@landfillbaby

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!

do i really need to sign the CLA for a single byte of changes? can't i just say it's WTFPL or something
edit: ok fine i did it

yeah looking at the original PRs that added this stuff, #7160 and #7681, it seems like without the with statements there's no proper memoryview deallocation, and a CopyFile[Ex]W implementation was reverted due to those functions copying too much with no flag to disable it (metadata, forks, etc)

i also just noticed it attempts a 2nd read after the case where output is less than the buffer size. unless that's intended i'm adding a break

This PR is stale because it has been open for 30 days with no activity.
