Support toolchain keyword (e.g. " nightly") to set override at root command #2031

BeniCheni · 2019-09-30T20:07:43Z

Support the toolchain keyword (e.g " nightly") to set override of the current working directory for toolchain, at the root command.

This PR should resolve #1498, as the local test is using similar test case to the reported command from the issue:

Test w. `rustup nightly target add wasm32-unknown-unknown`

→ rustup  nightly target add wasm32-unknown-unknown
info: using existing install for 'nightly-x86_64-apple-darwin'

Note: 97e6043 updated these:

added support for release channel support (i.e. "nightly")

→ rustup  stable which cargo
/Users/bchen/.rustup/toolchains/stable-x86_64-apple-darwin/bin/cargo

→ rustup  nightly which cargo                 
/Users/bchen/.rustup/toolchains/nightly-x86_64-apple-darwin/bin/cargo

→ rustup  foo which cargo                 
error: ' foo' isn't a valid value for '<release-channel>'
	[possible values:  beta,  nightly,  stable]


USAGE:
    rustup [FLAGS] [OPTIONS] [release-channel] <SUBCOMMAND>

For more information try --help

simplified some code based on clippy's suggestions
added tests

Per:

I believe there should be a warning

Would it be worth warning the user?

~~added warnings: (happy to edit the warning message to make better UX, if any suggestion)~~

→ rustup stable --toolchain=nightly which cargo
warning: Both toolchain keyword (e.g. " nightly") and "--toolchain" option are provided. The toolchain keyword would take precedence.
/Users/bchen/.rustup/toolchains/stable-x86_64-apple-darwin/bin/cargo

→ rustup --toolchain stable which rustc --toolchain=nightly
warning: Toolchain options are provided before and after the "which" subcommand. The first toolchain option would take precedence.
/Users/bchen/.rustup/toolchains/stable-x86_64-apple-darwin/bin/rustc

Update: current version does not need warning anymore.

BeniCheni · 2019-10-05T07:26:46Z

It may be better to transform the foo into --toolchain foo ...

@kinnison, sounds good. Updated per suggestion. PTAL at convenience? Thanks.

src/cli/rustup_mode.rs

BeniCheni · 2019-10-05T19:51:42Z

Why not just override toolchain instead of adding both toolchain-option and toolchain-keyword? There are supposed to be only one toolchain in effect though.

@pickfire, there's indeed only one toolchain (either by keyword or option format) in effect. Though the previous "toolchain-*" names were probably misleading. Updated to, hopefully, less confusing names (toolchain & keyword).

It may be better to transform the foo into --toolchain foo ..._"

The current logic is to follow @kinnison's suggestion ☝️ . I think the assignment of let toolchain = if let ... else block in "src/cli/rustup_mode.rs" already transforms " nightly" into toolchain.

If there's a way to omit Arg::with_name("keyword") setup, but still able to take foo input from CLI, I'm game to edit. Currently, I couldn't figure out any version how to receive foo input without the "keyword" arg.

src/cli/rustup_mode.rs

BeniCheni · 2019-10-07T02:31:48Z

pickfire
Why not just override toolchain in cfg and pass that in instead? We can keep the current version that way without adding a new parameter.

kinnison
That is a very good suggestion
then all commands will benefit since it's effectively altering the default toolchain entry from the config file.

@pickfire / @kinnison, after taking a step back and rethinking the approach, I also agree that overriding toolchain in cfg, and pass would have broader beneficial scope than just which. So the last push updated to just take "keyword" arg, and set override for the current dir accordingly.

I've tested w. the reported command from #1498: rustup nightly target add wasm32-unknown-unknown, and am able to verify the " nightly" keyword added the target in the correct rustup nightly toolchain path. Therefore, I think the PR is also resolving #1498 and edited the first comment of the PR w. reference. PTAL?

BeniCheni · 2019-10-08T03:26:17Z

@pickfire / @kinnison, updated 👇 per previous comments, and did some test about not saving settings in default profile. PTAL at convenience? (🤞feel really close to LGTY 😺)

Per tests/cli-misc.rs

pickfire
I wonder why are these changes necessary?

kinnison
Certainly this additional leading underscore isn't needed. However the conversion is needed afaict.

Indeed the leading underscore was my overlook. Updated. Also indeed the custom-1 to custom-2 conversion is to support the custom toolchain in the which test case.

Per src/cli/rustup_mode.rs

pickfire

I wonder if it would be helpful for the user experience if we use keyword here instead.

kinnison
Better would be toolchain rather than keyword

Tried out toolchain, but collided with subcommand toolchain and panicked. No worries. Ended using a common-ground name toolchain. Think it's contextual since the code strips the 1st character (i.e. " ") off to apply toolchain value. Hope it's okay w. you guys.

From an earlier comment

... we don't end up saving the different toolchain back if we do something (not expected, but possible) along the lines of rustup another set profile default -> alters both profile and default_toolchain in ~/.rustup/settings.toml

Tested rustup stable set profile default and verified content of settings.toml to ensure the default_toolchain is still nightly in the default profile.

→ rustup  stable set profile default
info: using existing install for 'stable-x86_64-apple-darwin'
info: override toolchain for '/Users/bchen/github/rustup.rs' set to 'stable-x86_64-apple-darwin'

  stable-x86_64-apple-darwin unchanged - rustc 1.38.0 (625451e37 2019-09-23)

info: profile set to 'default'

→ cat ~/.rustup/settings.toml
default_host_triple = "x86_64-apple-darwin"
default_toolchain = "nightly-x86_64-apple-darwin"
profile = "default"
version = "12"

[overrides]
"/Users/bchen/github/rustup.rs" = "stable-x86_64-apple-darwin"

kinnison

Looking good. Could you please add a test to assert that rustup stable set profile minimal doesn't affect the default toolchain?

pickfire · 2019-10-08T16:25:06Z

@BeniCheni Nice, looks good to me. Thanks a lot for taking this on.

Just left the test that @kinnison mentioned.

@kinnison, sure thing! Added tests per the helpful suggestion. Thank you. PTAL? 🙏

@BeniCheni Nice, looks good to me. Thanks a lot for taking this on.

Just left the test that @kinnison mentioned.

@pickfire, thank you! The version wouldn't have matured to the current version now, which could service all subcommed w. " toolchain". Gratitude for your time & effort to review. Please take a final look, if you have time? 🙏

@BeniCheni Oh, no worries. I was initially trying to do this but I cannot find how cargo do the nightly thing and I have no idea how to do that, I didn't know it is just as simple as

        .arg(
            Arg::with_name("toolchain")
                .help(TOOLCHAIN_ARG_HELP)
                .long("toolchain")
                .takes_value(true),
            Arg::with_name(" toolchain")
                .help("release channel (e.g.  stable) or custom toolchain to set override"),
        )

so I learned a lot as well. Either way, it is interesting to see how you use many different functions to piece this up.

The only thing I don't get is the need to have https://github.com/rust-lang/rustup.rs/pull/2031/files#diff-a11274be6e834e18a2579dad1b37ce8dR1173, but it does not matter much here.

@pickfire, I'm guessing the println!(); is simply to just print a new line. It's used in override_add where the logic & UX override_by_toolchain is aligning to; thus, the same line is in override_by_toolchain:

https://github.com/rust-lang/rustup.rs/blob/b9e968b6656dd999eb09fb6dc8e7952677dd3fc2/src/cli/rustup_mode.rs#L1176

pickfire · 2019-10-10T01:43:38Z

@BeniCheni Ah, I saw that there will always be a println! preceding show_channel_update, maybe I will send a patch to put that in show_channel_update to avoid the duplication.

kinnison

As it stands, this is not going to work because it stores a persistent override and is very noisy about doing so. We need to ensure that rustup foo ... doesn't affect any more than the individual execution.

src/cli/rustup_mode.rs

BeniCheni · 2019-10-22T06:24:18Z

... With an ephemeral toolchain entry in Cfg, then OverrideReason can gain a CommandLine variant, and then in Cfg::find_override() Ben can introduce a check for that before testing self.env_override

Greeting @kinnison. After the merge of #2075 and the suggestion from Discord ☝️ , I was able to follow along the similar idea and pushed an edit. PTAL at next convenience?

Here's some local testing w. the edited version:

@kinnison, nice suggestion for those UX tweaks. Added a validator, the OverrideReason::CommandLine and updated tests accordingly. PTAL? Thanks!

This appears to behave as desired. 👍
