This commit ensures that `fs::create_dir*` isn't called throughout Cargo
and is instead routed through our own wrapper `paths::create_dir_all`
which brings with it a few benefits:
* Gracefully handles when the directory already exists (which is the
behavior we always want anyway)
* Includes the path name in the error message of what failed
* Handles races of creating a directory by default
Closes#7304
Replace the duplicate .cwd call with an invocation taken from
https://stackoverflow.com/a/3138925/463761
Match the semantics of the other vcs calls, which is invoke from 'cwd'
targeting 'path'. Looks a little confusing because hg takes a '--cwd'
argument.
[Pijul](https://pijul.org) is a version control system written in Rust. This commit adds the ability to create a cargo project using pijul as the vcs for the project.
To use it, run `cargo new my-awesome-project --vcs=pijul`
The option in ~/.cargo/config is now called `vcs` and has the following
options: "git", "hg", and "none". This corresponds to the options for
the --vcs argument to `cargo new`.
This also fixes detection for hg repositories. Previously, we only tried
to discover if the working directory was contained in a git repository.
If it was, we would skip creating a git repo. Now, we check if the
working directory is contained in either a git or mecurial repo. If it
is, we skip creating a new repo.
Fixes#1116
