matklad · 2018-03-14T13:34:18Z

Several tests for cargo are failing due difference between clap and docopt.

Not exactly, it's because the tests are using error messages from clap version X, and on rust-lang/rust, clap is on version Y. Guess I'll need to loosen tests up a bit!

matklad · 2018-03-14T13:44:11Z

On the other hand, the easier route is just to update clap here :)

I am not 100% sure that relaxing the tests would be a better solution: it's important to check that the error messages actually look reasonable to protect from, say, potential clap regressions.

Perhaps updating the error messages once in a while won't be such a big chore in practice? Note that we'll hit the need of update in Cargo first, because its CI does not use lockfile, and always uses the latest clap.

This notably includes * rust-lang/cargo#5152 * rust-lang/cargo#5188 The first one switches cargo from docopt to clap ( we also update to the latest calp in this repository), the second one should help us to unify feature flags for Cargo itself and RLS, and build Cargo libray only once.

matklad · 2018-03-18T14:03:51Z

The RLS itself is already updated (rust-lang/rls@c0f07b3), so only submodule update in rust-lang/rust is required.

kennytm · 2018-03-18T14:23:48Z

Thanks @matklad! I'll include this into #49134 then.

messense · 2018-03-19T03:56:31Z

I am not sure if it's related to this, but it seems that third party Cargo commands no longer work by executing cargo whatever-third-party-command? For example I am using cargo-update:

$ cargo install-update -a
error: The subcommand 'install-update' wasn't recognized
	Did you mean 'install'?

If you believe you received this message in error, try re-running with 'cargo -- install-update'

USAGE:
    cargo [OPTIONS] [SUBCOMMAND]

For more information try --help

$ cargo -- install-update -a
error: The subcommand 'install-update' wasn't recognized
	Did you mean 'install'?

If you believe you received this message in error, try re-running with 'cargo -- install-update'

USAGE:
    cargo [OPTIONS] [SUBCOMMAND]

For more information try --help

Stable works fine:

$ cargo +stable install-update -a
    Updating registry `https://github.com/rust-lang/crates.io-index`

Package                          Installed      Latest         Needs update

matklad · 2018-03-19T06:12:39Z

Thank you so much for the report @messense ! Opened an issue at the Cargo tracker: rust-lang/cargo#5201, and investigating.

Looks like not every external subcommand is broken, only those that are named closely to the built-in ones.

Update clap This should fix a regression in Cargo after swithing to clap, when an external subcommand was not discovered, if its name was close to a built in command. bug report: #48986 (comment) fix: clap-rs/clap#1215
