feat (publish): deprecate `--token` option by omskscream · Pull Request #16046 · rust-lang/cargo

What does this PR try to resolve?

Closes #15274
This PR adds a warning when --token option is used with cargo publish command.
This PR removes --token from help and docs for publish command.

There's an --index option that still requires --token to be specified, but addressing that is not the part of this PR.

Please check changed test cases to see how behavior changes.

…about env variables

Not sure if we also want to update our test

cargo/tests/testsuite/publish.rs

Line 208 in 029de48

p.cargo("publish --no-verify --token sekrit --registry dummy-registry")

I was under impression that this test checks something specific to the cmd option, so wasn't sure about changing it except for adding a warning message 🤔

Anyway, it is fine keeping as-is.

-This command requires you to be authenticated with either the `--token` option
-or using [cargo-login(1)](cargo-login.html).
+This command requires you to be authenticated using [cargo-login(1)](cargo-login.html) 
+or [environment variables](../reference/environment-variables.html).


Probably instead of pointing to the entire env doc, we make the link a bit precise to relevant config fields. What do you think?

Suggested change

or [environment variables](../reference/environment-variables.html).

or environment variables of the [`registry.token`](../reference/config.html#registrytoken)

and [`registries.<name>.token`](../reference/config.html#registriesnametoken) config fields.

Though I am still wanting something similar to this happening: https://rust-lang.zulipchat.com/#narrow/channel/246057-t-cargo/topic/Anchors.20for.20each.20environment.20variable.20in.20The.20Cargo.20Book

Perhaps related:

Can be overridden with the --token command-line option.

This in both registry.token and registries.<name>.token doc might need to remove

Thanks for the edit, I missed the fact that config page has direct mentions of env variables with links 😥

As for

This in both registry.token and registries..token doc might need to remove

I would not do it in this PR, because --token is still used in yank and owner commands. Let's postpone it until the deprecation is done in all places.

That is fair. Thank you!

Created an issue tracking it: #16049

I overlooked in completion code we also want to hide --token

cargo/src/etc/_cargo

Line 254 in 029de48

'--token=[specify token to use when uploading]:token' \

cargo/src/etc/cargo.bashcomp.sh

Line 76 in 029de48

local opt__publish="$opt_common $opt_mani $opt_feat $opt_lock $opt_parallel --allow-dirty --dry-run --token --no-verify --index --registry --target --target-dir"

Fine with either dealing with it in this or a follow-up

Updated, thanks for reminder. I, as a Windows user, haven't even thought of autocomplete 😅

We have unstable native completion support also for powershell, if you're a user and wanna try: https://doc.rust-lang.org/cargo/reference/unstable.html#native-completions
