This brings in a commit which enables global template options by default as part
of initializing new git repositories, allowing a templates to be used as part of
`cargo new`.
Closes#498
Update git2-rs to the latest version which includes a fix for `extern crate`
syntax changes. This version changes the interface for credential callbacks,
so update the git source provider code as well.
This commit updates git2-rs to get the implementation of the authentication
callback in libgit2. Additionally this specifies the callback for whenever we're
cloning into the database or updating submodules.
Currently cargo will *not* ask for user input, but rather require you to have
authentication configured in git through some other means. There are currently
two primary methods of doing so:
1. Any SSH key in the local ssh-agent will be used for authentication with SSH
repositories.
2. The `credential.helper` interface (as specified by gitcredential(7)) has been
implemented in git2-rs to allow for picking up of storage of passwords in the
local git cache or keychain.
If these two methods fail, then there will likely be an authentication failure.
Interactive prompts for authentication have not been implemented as there is no
method to currently enter your password into the terminal silently.
A consequence of this commit is that cargo now depends on libssh2. A package was
created to create a static copy of libssh2, and this is now linked into cargo by
default.
It turned out that just building libssh2 was quite a beast in and of itself on
windows. The primary stickler point is that on the current release, 1.4.3,
libssh2 requires openssl on windows. At this time I don't want to pick up a
dependency on openssl for windows, and it turned out that the unreleased 1.4.4
version has a new backend for windows not based on openssl, but rather windows's
cryptography API.
The current bundled version of libssh2 is 1.4.4 with some light modifications to
actually build on windows (wow that was hard). All in all, we're now statically
linking to libssh 1.4.4 (not a runtime dependency).
Closes#493
It turned out most of the methods in libgit2 don't actually require a Signature
structure, they're all mostly optional. This commit updates to this version of
libgit2 where the arguments are all optional.
An upstream PR for libgit2 was applied locally, modified to build, and then
git2-rs was updated to use this small for of libgit2. This adds https support
via winhttp on mingw for windows users.
This command will assemble the current package into a tarball ready for
uploading to the cargo registry. Currently no further verification is done
beyond packaging the local repository into a tarball, but in the future this
could execute other operations such as api stability tools.
In general relying on external programs is dicey and tricky as they're very
different across systems in both how they're used as well as what versions
you'll find. Instead of binding to the least common denominator of CLI, we can
code against an exact version of libgit2.
This introduces a build-time dependency on cmake which libgit2 requires to build
itself, which is unfortunate, but thankfully it's only a build time dep. The
build process for libgit2 also automatically detects as many system libraries as
possible to use (if available), falling back to bundled versions if not
available. I have currently not figured how to control this, so the link-config
package is used to build libgit2 which requires that pkg-config be installed to
build cargo as well.
Closes#138
