The `anyhow` crate interoperates with the `std::error::Error` trait
rather than a custom `Fail` trait, and this is the general trend of
error handling in Rust as well.
Note that this is mostly mechanical (sed) and intended to get the test
suite passing. As usual there's still more idiomatic cleanup that can
happen, but that's left to later commits.
Pulls in alexcrichton/curl-rust#304 which fixes a bug from the last curl
update in #7308. This bug was not introduced by the Cargo PR itself but
rather by updating the `curl` submodule in the `curl-sys` crate. Without
this bugfix all downloads of a crate will make a new connection to
crates.io, which drastically increases download time since setting up a
connection takes so long.
Extract Platform to a separate crate.
This moves the `Platform`, `Cfg`, `CfgExpr` types to a new crate named "cargo-platform". The intent here is to give users of `cargo_metadata` a way of parsing and inspecting cargo's platform values.
Along the way, I rewrote the error handling to remove `failure`, and to slightly improve the output.
I'm having doubts whether or not this is a good idea. As you can see from the `examples/matches.rs` example, it is nontrivial to use this (which also misses cargo's config values and environment variables). I don't know if anyone will actually use this. If this doesn't seem to have value, I would suggest closing it.
I've also included a sample script, `publish.py`, for publishing cargo itself. I suspect it will need tweaking, but I figure it would be a start and open for feedback.
Don't require the `serde` feature of `url`
Ends up meaning that in full crate compiles that `url` doesn't wait for
`serde` to finish, which in turn enables crates like `git2` to start
sooner!
Experiment: Create timing report.
This is just an experiment, so I'm not sure if we'll want to merge it.
This adds an HTML report which gets saved to disk when the build is finished. It is primarily geared for identifying slow dependencies, and for visualizing how pipelining affects the build.
Here's an example: https://ehuss.github.io/cargo-timing.html
You can mouse over the blocks to highlight the reverse-dependencies that are released when a unit finishes. `syn` is a really good example.
It does a few other things, like displaying a message after each unit is finished. See the docs for more information.
This home's release remove support for the old `.multirust`
directory. Also it fixes rustup_home and cargo_home implementation
when corresponding environment variables are absolute paths.
Instead of treating Windows differently, this just always uses canonical paths
on all platforms. This fixes a problem where symlinks were not treated
correctly on all platforms.
Switching rm_rf to the remove_dir_all crate because deleting symbolic links on
Windows is difficult.
Tighten requirements for git2 crates
Bring in a few updates, used to update libgit2 and fix a Windows issue
as well as updating the `url` dependencies.
Closes#7173
This commit fixes a test in Cargo to work around a seeming regression in
behavior in libgit2 around HTTP authentication. The expected flow for
HTTP authentication with git is that git sends an HTTP request and
receives an "unauthorized" response. It then sends another request with
authorization information and that's what we're testing is received in
the our test.
Previously libgit2 would issue a new HTTP connection if the previous one
was closed, but it looks like changes in libgit2 now require that the
same HTTP connection is used for the initial request and the subsequent
request with authorization information. This broke our test since it's
not using an HTTP compliant server at all and is just some handwritten
TCP reads/writes. The fix here is to basically stay with handwritten TCP
reads/writes but tweak how it happens so it's all on the same HTTP/TCP
connection to match what libgit2 is expecting.
Some extra assertions have also been added to try to prevent deadlocks
from happening in the future and instead make the test fail fast if this
situation comes up again.
These tests take a good amount of time to run locally and they're also
causing a lot of dependencies to get pulled into rust-lang/rust, so
let's have a separate crate that we just test on our own CI
