[issue40334] PEP 617: new PEG-based parser

[issue40654] shutil.copyfile mutates symlink for absolute path

Steve Dower added the comment: This is only an issue for broken symlinks, right? (More precisely, those that cannot be resolved, which may include very long paths on some machines.) Fixing copy is my preferred option. Also Jason, what do you need to be able to test against prerelease? It

[issue40629] Error MSB4086 (numeric comparison)

Steve Dower added the comment: Yeah, that looks like a version of .NET that pre-dates Version being made comparable, which probably means you're not getting the MSBuild installed with VS. Check out "where MSBuild" or %MSBUILD% to see if there's something obvious overriding it, and use the

[issue38938] Possible performance improvement for heaqq.merge()

Dennis Sweeney added the comment: I mostly like new_merge.py too, especially the dynamic reduction of the tree. However, it looks like ``list(merge([2],[1],[1]))`` currently fails, and I think what's missing is the following in the sibling-promotion: + if sibling.left is not

[issue40668] Catastrophic loss of precision in colorsys module

New submission from Zac Hatfield-Dodds : As part of the Mentored Sprints at PyCon US, Marielle wrote some property-based tests [1] for the colorsys module [2], which found two bugs. Taking a YIQ color, converting to RGB, and back to YIQ can result in the Y coordinate varying by more 0.1
