This commit implements a simple warning to indicate when `DefaultBranch`
is unified with `Branch("master")`, meaning `Cargo.toml` inconsistently
lists `branch = "master"` and not. The intention here is to ensure that
all projects uniformly use one or the other to ensure we can smoothly
transition to the new lock file format.
This commit implements a warning in Cargo for when a dependency
directive is using `DefaultBranch` but the default branch of the remote
repository is not actually `master`. We will eventually break this
dependency directive and the warning indicates the fix, which is to
write down `branch = "master"`.
This commit is intended to be an effective but not literal revert
of #8364. Internally Cargo will still distinguish between
`DefaultBranch` and `Branch("master")` when reading `Cargo.toml` files,
but for almost all purposes the two are equivalent. This will namely fix
the issue we have with lock file encodings where both are encoded with
no `branch` (and without a branch it's parsed from a lock file as
`DefaultBranch`).
This will preserve the change that `cargo vendor` will not print out
`branch = "master"` annotations but that desugars to match the lock file
on the other end, so it should continue to work.
Tests have been added in this commit for the regressions found on #8468.
This commit improves Cargo's support for git repositories whose "main
branch" is not called `master`. Cargo currently pretty liberally assumes
that if nothing else about a git repository is specified then `master`
is the branch name to use. Instead now Cargo has a fourth option as the
desired reference of a repository named `DefaultBranch`. Cargo doesn't
know anything about the actual name of the default branch, it just
updates how git references are fetched internally.
This commit is motivated by news that GitHub is likely to switch away
from the default branch being named `master` in the near future. It
would be a bit of a bummer if from now on everyone had to type
`branch = '...'`, so this tries to improve that!
This commit refactors various logic of the git source internals to
ensure that if we have a locked revision that we plumb the desired
branch/tag all the way through to the `fetch`. Previously we'd switch to
`Rev` very early on, but the fetching logic for `Rev` is very eager and
fetches too much, so instead we only resolve the locked revision later
on.
Internally this does some various refactoring to try to make various
bits and pieces of logic a bit easyer to grok, although it's still
perhaps not the cleanest implementation.
Commit 3d6de4177489a5d450f35e92288512be85492678 (#3998) made cargo
ignore Cargo.toml files that are invalid TOML in a git source.
This change further ignores Cargo.toml files that are valid TOML but
cannot really be loaded.
This is potentially an alternative fix for #6822.
`cargo vendor`: Don't delete hidden top-level files.
`cargo vendor` (without `--no-delete`) will delete all files in the `vendor/` directory when it starts. This changes it so that it will skip any entries starting with a dot. This allows one to track the vendor directory with a source control system like git.
Closes#7109
(Note: two commits, one is a test change.)
This commit disables usage of git templates whenever Cargo manages
repositories in its internal git database. Templates don't want to be
used at all in these situations and have been known to cause usability
bugs.
Closes#6240
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.
