libgit2 Git开发包
libgit2 是一个可移植、纯C语言实现的 Git 核心开发包，你可以使用它来编写自定义的 Git 应用。
libgit2 v0.24.0 RC1 发布，该版本包含众多变化，详细列表包括：
Custom filters can now be registered with wildcard attributes, for
example filter=*. Consumers should examine the attributes parameter
of the check function for details.
Symlinks are now followed when locking a file, which can be
necessary when multiple worktrees share a base repository.
You can now set your own user-agent to be sent for HTTP requests by
using the GIT_OPT_SET_USER_AGENT with git_libgit2_opts().
You can set custom HTTP header fields to be sent along with requests
by passing them in the fetch and push options.
Tree objects are now assumed to be sorted. If a tree is not
correctly formed, it will give bad results. This is the git approach
and cuts a significant amount of time when reading the trees.
Filter registration is now protected against concurrent
registration.
Filenames which are not valid on Windows in an index no longer cause
to fail to parse it on that OS.
Rebases can now be performed purely in-memory, without touching the
repository's workdir.
git_config_lock() has been added, which allow for
transactional/atomic complex updates to the configuration, removing
the opportunity for concurrent operations and not committing any
changes until the unlock.
git_diff_options added a new callback progress_cb to report on the
progress of the diff as files are being compared. The documentation of
the existing callback notify_cb was updated to reflect that it only
gets called when new deltas are added to the diff.
git_fetch_options and git_push_options have gained a custom_headers
field to set the extra HTTP header fields to send.
git_stream_register_tls() lets you register a callback to be used
as the constructor for a TLS stream instead of the libgit2 built-in
one.
git_commit_header_field() allows you to look up a specific header
field in a commit.
git_commit_extract_signature() extracts the signature from a
commit and gives you both the signature and the signed data so you
can verify it.
There were no API removals in this release.
The git_merge_tree_flag_t is now git_merge_flag_t. Subsequently,
its members are no longer prefixed with GIT_MERGE_TREE_FLAG but are
now prefixed with GIT_MERGE_FLAG, and the tree_flags field of the
git_merge_options structure is now named flags.
The git_merge_file_flags_t enum is now git_merge_file_flag_t for
consistency with other enum type names.
git_cert descendent types now have a proper parent member
It is the responsibility of the refdb backend to decide what to do
with the reflog on ref deletion. The file-based backend must delete
it, a database-backed one may wish to archive it.
git_config_backend has gained two entries. lock and unlock
with which to implement the transactional/atomic semantics for the
configuration backend.
git_index_add and git_index_conflict_add() will now use the case
as provided by the caller on case insensitive systems. Previous
versions would keep the case as it existed in the index. This does
not affect the higher-level git_index_add_bypath or
git_index_add_frombuffer functions.
The notify_payload field of git_diff_options was renamed to payload
to reflect that it's also the payload for the new progress callback.
The git_config_level_t enum has gained a higher-priority value
GIT_CONFIG_LEVEL_PROGRAMDATA which represent a rough Windows equivalent
to the system level configuration.
git_rebase_init() not also takes a merge options.
The index no longer performs locking itself. This is not something
users of the library should have been relying on as it's not part of
the concurrency guarantees.
