Add functions to use convert a string with length, instead of assuming
NUL termination.
In addition, move the utf8 to 16 conversion routines into the `git_utf8`
namespace instead of using namespaceless `git__` prefixed names.
Name the GSSAPI and ntlmclient authentication providers as such. Today
they're named after the authentication mechanism ("Negotiate", "NTLM")
instead of their implementation.
If we have competing implementations for the same mechanism (eg, a
future Windows SSPI-based provider for Negotiate and NTLM) then this
will get confusing.
Provide a stream interface for Schannel - the native crypto APIs - on
Windows. This allows Windows to use the same HTTP transport that all the
other platforms use, with its own native crypto.
Ultimately this allows us to deprecate WinHTTP and we need not add
support for our socket changes in two places (our HTTP stack and the
WinHTTP stack).
It is a bit too hidden why we want 64 bits when we're assigning to a 32-bit
integer later on to store the number of objects, so go back to uint32_t and cast
to uint64_t during the size calculation.
When the contents of an entire new directory is ignored, and `FORCE` is
specified to `git_index_add_all`, ensure that we expand the entire file
list. By default, diff will coalesce a fully ignored folder into a
single diff entry; expand it.
The `git_fs_path_owner_is_current_user` expects the root dir on unix
(`/`) to be owned by a non-current user. This makes sense unless root
(or euid == 0) is running the tests, which often happens during distro
build / packaging scripts. Allow them to run the tests.
This improves the documentation for `git_repository_is_empty`
which currently does not accurately describe libgit2's definition
of "empty".
It says that HEAD must point to the "unborn master branch", when
in fact, this is not the case if the repo's `init.defaultBranch`
configuration is set. If it is set, it will check that HEAD points
there. Only if it is not set does it fall back to `master`.
`git_odb_stream` should have an `oid_type` to disambiguate; that's not
necessary on non-experimental SHA256 builds. Avoid unnecessary ABI
breakage for consumers and hide it behind an ifdef for now.
The remote::httpproxy::env test (correctly) reset the environment before
running; however the other tests are also impacted by the environment
and need to have it isolated.
