This has bothered me about `cargo new` and `cargo init` for a while that
the output is read backwards, for example:
```diff

Before, we'd render the source for TOML syntax errors but not semantic errors.
Now we render for both.
Originally I changed `parse_document` to returned `T: DeserializeOwned`
but that adds an extra "could not parse TOML" which is both redundant
and makes it sound like its a syntax issue.
Rustc supports these since rust-lang/rust#109808. It's technically
possible to set a named debuginfo level through `RUSTFLAGS`, but in
practice cargo always passes its own opinion of what the debuginfo level
is, so allow it to be configured through cargo too.
This allows to use `gitoxide` for all fetch operations, boosting performance
for fetching the `crates.io` index by a factor of 2.2x, while being consistent
on all platforms.
For trying it, nightly builds of `cargo` can specify `-Zgitoxide=fetch`.
It's also possible to set the `__CARGO_USE_GITOXIDE_INSTEAD_OF_GIT2=1` environment
variable (value matters), which is when `-Zgitoxide=none` can be used
to use `git2` instead.
Limitations
-----------
Note that what follows are current shortcomings that will be addressed in future PRs.
- it's likely that authentication around the `ssh` protocol will work differently in practice
as it uses the `ssh` program.
- clones from `file://` based crates indices will need the `git` binary to serve the locatl repository.
- the progress bar shown when fetching doesn't work like the orgiinal, but should already feel 'faster'.
Switch some tests from `build` to `check`
#11341 brought up issues with cargo's `testsute` size and speed. One of the suggested fixes was switching most tests to `check` instead of `build`. This PR did that.
Before size on `nightly`: 4.4GB
After size on `nightly`: 4.2GB
Regex to find `build` in `tests/testsuite`: `cargo\(".*build.*\)`
Before: 1607
After: 626
Note I did not remove all `build` I only did the easy ones that required minimal changes. I also tried not to touch systems I was unsure about. There could be other uses of `build` I missed as well.
I still need to play around with `opt-level`, `debug=0`, and a few other tweaks, but there should be more time/memory to drop.
Each test file changed is in a commit of its own, so you should look commit by commit.
Benefits:
- A TOML 1.0 compliant parser
- Unblock future work
- Have `cargo init` add the current crate to the workspace, rather
than error
- #5586: Upstream `cargo-add`
- `set_require_newline_after_table` was added in #2680 back in 2016
- `set_allow_duplicate_after_longer_table` was added in #6761 in 2019
Several years later, this PR is turning these warnings into errors.
The function and documentation was kept so we can add additional hacks
in the future, like if we switch TOML parsers.
Named profile updates
A few updates for named profiles to push them closer to stabilization:
- Disable the `dir-name` profile setting. `dir-name` primarily exists for translating the built-in profiles or sharing artifacts between profiles. In order to simplify the UI, we would like to not expose it to the user for the initial stabilization. The code to support it is kept in case we want to add it in the future.
- Reserve some profile names. Just to give a little flexibility in the future in case we want to use these, or that they could cause confusion. Also updated the error text a little.
- Add support for custom profiles to legacy commands. Their old behavior is still retained for backwards compatibility. That is:
* `cargo check`
* `--profile=test`: This forces the test mode. For example, `cargo check --lib --profile=test` will check the library as a unit test (with `--test`).
* `cargo fix`
* `--profile=test`: Forces test mode, same as above.
* `cargo rustc`
* `--profile=test`: Forces test mode, same as above.
* `--profile=bench`: Forces bench mode.
* `--profile=check`: Forces check mode.
- These commands also allow mixing the above options with `--release`, which is normally not allowed.
- Fix `cargo bench` to support the `--profile` option. I think it was just forgotten.
Just to give a little flexibility in the future in case we want to use
these, or that they could cause confusion. Also updated the error text a
little.
I don't trust that all these transformations won't have unintended
consequences on other platforms. It is nice to verify there aren't any
backslash shenanigans on other platforms.
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.
There's an existing bug (#7782) in Cargo which exacerbates the issue
here but in general having a stack of errors is a bit easier to read and
work with than having a big long error message.
Fix CARGO_TARGET_triple_LINKER environment variable.
#7649 caused an unfortunate regression where the `CARGO_TARGET_triple_LINKER` environment variable stopped working. I did not realize `serde(flatten)` caused serde to switch to `deserialize_map` which does not support environment variables.
The solution here is to essentially revert back to how the `[target]` table used to be loaded by loading each key individually.
This also removes the `ar` field which is not used by `rustc`.
