Thanks! Do you think the documentation for PathBuf::push should also be updated to give some information about rust-lang/89270?

Good point, I've added some words.

See: #89658

Should this PR be marked as fixing that issue? (If so, change "See:" to "Fixes".)

Good point. I've changed it. I've also tested it more, all good as far as I can see.

With this change, the documentation you added above (about removing . and .. components) is no longer true for .push(""), right?

Yes, good catch.

I've changed the documentation to match the implementation.

Nominated for backport into 1.57, since #89658 was introduced in that version.

Thanks @seanyoung for the PR and @m-ou-se for the review!

seanyoung · 2021-10-25T17:49:02Z

@m-ou-se just wanted to check that this is getting merged to 1.57.0 as you said. It is not present on the beta branch in the rust repo, and also note this above:

rustbot added this to the 1.58.0 milestone 3 days ago

m-ou-se · 2021-10-25T21:00:24Z

@seanyoung This will be merged into 1.57 in a separate PR. The beta-nominated and beta-accepted labels track that. Nominated means the decision still needs to be made. Both labels together means the decision to backport has been made, but it still has to be backported. Then when someone makes a backport PR they'll know to include this patch too. Once that's merged, the nominated label will be removed. Before releasing a new version, all PRs with beta-nominated are checked first, so don't worry about it missing the release.

Since this was already discussed in the team meeting, I've marked it as beta-accepted.

(The bug report itself is also marked with the 1.57 milestone, which means someone will look at it before 1.57 is released.)
