- One parser change found by `cargo_config::includes` is that clap 2
would ignore any values after a `=` for flags.
`cargo config --show-origin` is a flag but the test passed `--show-origin=yes` which
happens to give the desired result for that test but is the same as
`--show-origin=no` or `--show-origin=alien-invasion`.
- The parser now panics when accessing an undefined attribute but clap
takes advantage of that for sharing code across commands that have
different subsets of arguments defined. I've extended clap so we can
"look before you leap" and put the checks at the argument calls to
start off with so its very clear what is tenuously shared. This
allows us to go in either direction in the future, either addressing
how we are sharing between commands or by moving this down into the
extension methods and pretending this clap feature doesn't exist
- On that topic, a test found clap-rs/clap#3263. For now, there is a
hack in clap. Depending on how we fix that in clap for clap 4.0, we
might need to re-address things in cargo.
- `value_of_os` now requires setting `allow_invalid_utf8`, otherwise it
asserts. To help catch this, I updated the argument definitions
associated with lookups reported by:
- `rg 'values?_os' src/`
- `rg 'values?_of_os' src/`
- clap now reports `2` for usage errors, so we had to bypass clap's
`exit` call to keep the same exit code.
BREAKING CHANGE: API now uses clap3
Support `term.quiet` configuration
Fixes#10128
This follows the existing support for `--verbose` and `term.verbose`.
I've renamed the related tests to be a bit clearer now there are more cases, and the existing quiet tests now prove that they hide the cargo log.
I'm unsure whether I'm supposed to regenerate the documentation as part of this?
Of the options people regularly pass to cargo, `--release` seems by far
the most common. Yet even on the command line, we expect people to type
out `--release`.
Add a short version `-r`, and add some tests in the testsuite that
confirm it works.
"exit code" is wrong terminology on Unix. I am trying to fix this in
Rust stdlib in
https://github.com/rust-lang/rust/pull/83462
but this currently breaks the cargo test suite.
See that MR for full explanation of the change.

This commit is targeted at further improving the error messages
generated from git errors. For authentication errors the actual URL
fetched is now printed out as well if it's different from the original
URL. This should help handle `insteadOf` logic where SSH urls are used
instead of HTTPS urls and users can know to track that down.
Otherwise the logic about recommending `net.git-fetch-with-cli` was
tweaked a bit and moved to the same location as the rest of our error
reporting.
Note that a change piggy-backed here as well is that `Caused by:` errors
are now automatically all tabbed over a bit instead of only having the
first line tabbed over. This required a good number of tests to be
updated, but it's just an updated in renderings.
This commit refactors the internals of Cargo to no longer have a
singular `--target` flag (and singular `requested_target` kind throught)
but to instead have a list. The semantics of multiple `--target` flags
is to build the selected targets for each of the input `--target` flag
inputs.
For now this is gated behind `-Zmultitarget` as an unstable features,
since I'm not entirely sure this is the interface we want. In general
it'd be great if we had a way to simply specify `Unit` structures of
what to build on the CLI, but we're in general very far away from that,
so I figured that this is probably sufficient at least for testing for
now.
cc #8156
This commit is the Cargo half of support necessary for
rust-lang/rust#70458. Today the compiler emits embedded bytecode in
rlibs by default, but compresses it. This is both extraneous disk space
and wasted build time for almost all builds, so the PR in question there
is changing rustc to have a `-Cembed-bitcode` flag which, when enabled,
places the bitcode in the object file rather than an auxiliary file (no
extra compression), but also enables `-Cembed-bitcode=no` to disable
bitcode emission entirely.
This Cargo support changes Cargo to pass `-Cembed-bitcode=no` for almost
all compilations. Cargo will keep `lto = true` and such working by not
passing this flag (and thus allowing bitcode to get embedded), but by
default `cargo build` and `cargo build --release` will no longer have
any bitcode in rlibs which should result in speedier builds!
Most of the changes here were around the test suite and various
assertions about the `rustc` command lines we spit out. One test was
hard-disabled until we can get `-Cembed-bitcode=no` into nightly, and
then we can make it a nightly-only test. The test will then be stable
again once `-Cembed-bitcode=no` hits stable.
Note that this is intended to land before the upstream `-Cembed-bitcode`
change. The thinking is that we'll land everything in rust-lang/rust all
at once so there's no build time regressions for anyone. If we were to
land the `-Cembed-bitcode` PR first then there would be a build time
regression until we land Cargo changes because rustc would be emitting
uncompressed bitcode by default and Cargo wouldn't be turning it off.
This commit starts to lay the groundwork for #6660 where Cargo will
invoke rustc in a "pipelined" fashion. The goal here is to execute one
command to produce both an `*.rmeta` file as well as an `*.rlib` file
for candidate compilations. In that case if another rlib depends on that
compilation, then it can start as soon as the `*.rmeta` is ready and not
have to wait for the `*.rlib` compilation.
Initially attempted in #6864 with a pretty invasive refactoring this
iteration is much more lightweight and fits much more cleanly into
Cargo's backend. The approach taken here is to update the
`DependencyQueue` structure to carry a piece of data on each dependency
edge. This edge information represents the artifact that one node
requires from another, and then we a node has no outgoing edges it's
ready to build.
A dependency on a metadata file is modeled as just that, a dependency on
just the metadata and not the full build itself. Most of cargo's backend
doesn't really need to know about this edge information so it's
basically just calculated as we insert nodes into the `DependencyQueue`.
Once that's all in place it's just a few pieces here and there to
identify compilations that *can* be pipelined and then they're wired up
to depend on the rmeta file instead of the rlib file.
The macos dynamic linker behavior wrt DYLD_FALLBACK_LIBRARY_PATH is to
use the value it is set with, and if there is no such value (the
environment variable is either not set or set but empty), it uses a
default value of $HOME/lib:/usr/local/lib:/usr/lib.
Currently, cargo takes the value of DYLD_FALLBACK_LIBRARY_PATH, prepends
its paths to it, and then unconditionally adds
$HOME/lib:/usr/local/lib:/usr/lib, which in principle, shouldn't happen
if DYLD_FALLBACK_LIBRARY_PATH was set originally.
To avoid breaking other (external) callers of ops::run(), this adds a
new function ops::run_os() taking an &[OsString], and turns ops::run()
into a wrapper (keeping its original signature) that calls run_os().
This change ensures cargo will output file paths in the expected format
(C:\foo\... on Windows, /foo/... elsewhere). Previously it would output
file:// URLs instead.
To support this change, additional changes were made to the test suite
string processing such that [ROOT] is now replaced with the appropriate
file path root for the platform.
The CWD template was also updated to use [CWD] like other replacement
templates and to do the replacement on the expected value rather than
the actual value to avoid replacing things we don't expect with CWD.
This commit stabilizes the `edition` key in `Cargo.toml`, both in the
`[package]` section and inside subtargets. Additionally the `cargo new` and
`cargo init` subcommands have been enhanced with a `--edition` flag to allow
explicitly specifying the edition to be generated.
This commit does not yet change the default edition that's generated.
