Tracking issue: #6797

This stabilizes the install-upgrade feature, which causes cargo install to reinstall a package if it appears to be out of date, or exit cleanly if it is up-to-date.

There are no changes from -Zinstall-upgrade. See the old unstable docs for a refresher on the details of what it does.

This also stabilizes the following changes:

  • --version no longer allows an implicit version requirement like 1.2. It must be either contain all 3 components (like 1.2.3) or use a requirement operator (like ^1.2). This has been a warning for a very long time, and is now changed to a hard error.
  • Added --no-track to disable install tracking.

Motivation

I just personally prefer this behavior, and it has been requested a few times in the past. I've been using it locally, and haven't run into any issues. If this goes into 1.41, then it will release on Jan 30, about 10 months since it was added in #6798.

Concerns

Regarding some of the concerns I had:

  • Is it tracking the correct set of information?

    I'm satisfied with the current set. It also tracks, but does not use, the version of rustc and the version specified in the --version flag, in case we ever want to use that in the future. It is also designed to be backwards and forwards compatible, so more information can be added in the future. I think the current set strikes a good balance of tracking the really important things, without causing unnecessary rebuilds.

  • Method to upgrade all outdated packages?

    This can always be added as a new flag or command in the future, and shouldn't block stabilization.

  • Should --no-track be kept? Does it work correctly?

    I kept it. It's not too hard to support, and nobody said anything (other than maybe using a less confusing name).

  • Should this be the default? Should there be a way to use the old behavior?

    I like it as the default, and don't see a real need for the old behavior. I think we could always bring back the old behavior with a flag in the future, but I would like to avoid it for simplicity. There is also the workaround of which foo || cargo install foo.

Closes #6797.
Closes #6727.

Stabilize install-upgrade.

Tracking issue: #6797

This stabilizes the install-upgrade feature, which causes `cargo install` to reinstall a package if it appears to be out of date, or exit cleanly if it is up-to-date.

There are no changes from `-Zinstall-upgrade`. See [the old unstable docs](https://github.com/rust-lang/cargo/blob/6a7f505a185b000e38bdad64392098e0b2e50802/src/doc/src/reference/unstable.md#install-upgrade) for a refresher on the details of what it does.

This also stabilizes the following changes:
- `--version` no longer allows an implicit version requirement like `1.2`.  It must be either contain all 3 components (like `1.2.3`) or use a requirement operator (like `^1.2`).  This has been a warning for a very long time, and is now changed to a hard error.
- Added `--no-track` to disable install tracking.

**Motivation**

I just personally prefer this behavior, and it has been requested a few times in the past. I've been using it locally, and haven't run into any issues. If this goes into 1.41, then it will release on Jan 30, about 10 months since it was added in #6798.

Version 1.41.0 (2020-01-30)
===========================

Language
--------

- [You can now pass type parameters to foreign items when implementing
  traits.][65879] E.g. You can now write `impl<T> From<Foo> for Vec<T> {}`.
- [You can now arbitrarily nest receiver types in the `self` position.][64325] E.g. you can
  now write `fn foo(self: Box<Box<Self>>) {}`. Previously only `Self`, `&Self`,
  `&mut Self`, `Arc<Self>`, `Rc<Self>`, and `Box<Self>` were allowed.
- [You can now use any valid identifier in a `format_args` macro.][66847]
  Previously identifiers starting with an underscore were not allowed.
- [Visibility modifiers (e.g. `pub`) are now syntactically allowed on trait items and
  enum variants.][66183] These are still rejected semantically, but
  can be seen and parsed by procedural macros and conditional compilation.

Compiler
--------

- [Rustc will now warn if you have unused loop `'label`s.][66325]
- [Removed support for the `i686-unknown-dragonfly` target.][67255]
- [Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.][66661]
- [You can now pass an arguments file passing the `@path` syntax
  to rustc.][66172] Note that the format differs somewhat from what is
  found in other tooling; please see [the documentation][argfile-docs] for
  more information.
- [You can now provide `--extern` flag without a path, indicating that it is
  available from the search path or specified with an `-L` flag.][64882]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

[argfile-docs]: https://doc.rust-lang.org/nightly/rustc/command-line-arguments.html#path-load-command-line-flags-from-a-path

Libraries
---------

- [The `core::panic` module is now stable.][66771] It was already stable
  through `std`.
- [`NonZero*` numerics now implement `From<NonZero*>` if it's a smaller integer
  width.][66277] E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
- [`MaybeUninit<T>` now implements `fmt::Debug`.][65013]

Stabilized APIs
---------------

- [`Result::map_or`]
- [`Result::map_or_else`]
- [`std::rc::Weak::weak_count`]
- [`std::rc::Weak::strong_count`]
- [`std::sync::Weak::weak_count`]
- [`std::sync::Weak::strong_count`]

Cargo
-----

- [Cargo will now document all the private items for binary crates
  by default.][cargo/7593]
- [`cargo-install` will now reinstall the package if it detects that it is out
  of date.][cargo/7560]
- [Cargo.lock now uses a more git friendly format that should help to reduce
  merge conflicts.][cargo/7579]
- [You can now override specific dependencies's build settings][cargo/7591] E.g.
  `[profile.dev.overrides.image] opt-level = 2` sets the `image` crate's
  optimisation level to `2` for debug builds. You can also use
  `[profile.<profile>.build_overrides]` to override build scripts and
  their dependencies.

Misc
----

- [You can now specify `edition` in documentation code blocks to compile the block
  for that edition.][66238] E.g. `edition2018` tells rustdoc that the code sample
  should be compiled the 2018 edition of Rust.
- [You can now provide custom themes to rustdoc with `--theme`, and check the
  current theme with `--check-theme`.][54733]
- [You can use `#[cfg(doc)]` to compile an item when building documentation.][61351]

Compatibility Notes
-------------------

- [As previously announced 1.41.0 will be the last tier 1 release for 32-bit
  Apple targets.][apple-32bit-drop] This means that the source code is still
  available to build, but the targets are no longer being tested and release
  binaries for those platforms will no longer be distributed by the Rust project.
  Please refer to the linked blog post for more information.
