There might be casses where we want to show pre-release as this grows
but, for now, there isn't too often a case where an update is held back,
you are on a pre-release, your pre-release is updating, and you want a pre-release.
`cargo update --precise` might pass in any arbitrary Git reference,
and `git2::Oid::from_str` would always zero-pad the given str if it is
not a full SHA hex string.
This introduces an enum `Revision` to represent `locked_rev`
that is either deferred or resolved to an actual object ID.
When `locked_rev` is a short ID or any other Git reference,
Cargo first performs a Git fetch to resolve it (without --offline),
and then locks it to an actual commit object ID.
Before, when running `cargo update <member>`, we'd not reuse the
previous resolve result and when the resolver started walking into the
dependencies, it would do a git fetch.
Now, we won't even try to resolve the workspace members and so we won't
look at those dependencies and do git fetch.
This will make `cargo update <workspace-member>`
match `cargo update --workspace`.
I considered whether there were other ways of handling this but I
figured aiming for consistency in approaches was the best way.
We can investigate improving those approaches separately.
There are other discrepancies in the different code paths (handling of
patches, adding sources) but I'm deferring looking over those.
Between this and #12602, this should finnally resolve#12599.
Fixes#12599
This addresses the ordering issue of for one of the problems from #12599.
The intent behind the `path_pkg` check is to make sure we update
workspace members in the lockfile if their version number changed.
In this case, we don't need to recursively walk, because the change
doesn't affect dependencies. However, we also shouldn't *prevent*
recursive walks which is what we are doing today, both for packages
marked to keep and for packages that have been "poisoned". So we fix
this by moving that call after all recursive adds are complete so as to
not interfere with them.
When working on cargo-upgrade, I found the meaning of `--aggressive`
confusing and named it `--recursive` there.
Renaming this in `cargo update` (with a backwards compatible alias) was
referenced in #12425.
Generally, cargo avoids positional arguments. Mostly for the commands
that might forward arguments to another command, like `cargo test`.
It also allows some flexibility in turning flags into options.
For `cargo add` and `cargo remove`, we decided to accept positionals
because the motivations didn't seem to apply as much (similar to `cargo
install`).
This applies the pattern to `cargo update` as well which is in the same
category of commands as `cargo add` and `cargo remove`.
As for `--help` formatting, I'm mixed on whether `[SPEC]...` should be at the top like
other positionals or should be relegated to "Package selection". I went
with the latter mostly to make it easier to visualize the less common
choice.
Switching to a positional for `cargo update` (while keeping `-p` for
backwards compatibility) was referenced in #12425.
After the rust_version field was stabilized in #9732 this adds the
rust_version as output to the `cargo metadata` command, so tools like
Clippy can read and use it as well.
This commit follows through with work started in #8522 to change the
default behavior of `git` dependencies where if not branch/tag/etc is
listed then `HEAD` is used instead of the `master` branch. This involves
also changing the default lock file format, now including a `version`
marker at the top of the file notably as well as changing the encoding
of `branch=master` directives in `Cargo.toml`.
If we did all our work correctly then this will be a seamless change.
First released on stable in 1.47.0 (2020-10-08) Cargo has been emitting
warnings about situations which may break in the future. This means that
if you don't specify `branch = 'master'` but your HEAD branch isn't
`master`, you've been getting a warning. Similarly if your dependency
graph used both `branch = 'master'` as well as specifying nothing, you
were receiving warnings as well. These two situations are broken by this
commit, but it's hoped that by giving enough times with warnings we
don't actually break anyone in practice.
Add "--workspace" to update command
My `--bin` project has CI which updates the version number in `Cargo.toml`, which it then commits. However, this means that any further cargo command (`build`, `test`, etc) will update the existing `Cargo.lock` file (updating the root version), causing some frustration for users. Furthermore, it breaks the `publish` command, which requires the repo to be current.
I've added a `sync-lockfile` command to simply update the root version in the `Cargo.lock` file to match the `Cargo.toml` in the same way that simple commands like `fetch` do. If no `Cargo.lock` file is present, and new one is generated based on the index.
This is a demo PR for Pre-RFC conversation at https://internals.rust-lang.org/t/pre-rfc-cargo-command-to-just-sync-lockfile/13119, but may become a real PR if it gets approval.
Prior to this commit `cargo metadata` would not emit the value of a
target's "doc" setting, used by `cargo doc` to determine whether
documentation should be generated. However, this information is useful
for machine programs interested in such targets, and the information is
already made available on the internal representation of a target, so
this commit just exposes that during target serialization for emit.
