libgit2 2017/6/19
This is the first release of the v0.26 series, "Aufschub". The changelog follows.
Changes or improvements
Support for opening, creating and modifying worktrees.
We can now detect SHA1 collisions resulting from the SHAttered attack. These
checks can be enabled at build time via -DUSE_SHA1DC.
Fix for missing implementation of git_merge_driver_source getters.
Fix for installed pkg-config file being broken when the prefix contains
spaces.
We now detect when the hashsum of on-disk objects does not match their
expected hashsum.
We now support open-ended ranges (e.g. "master..", "...master") in our
revision range parsing code.
We now correctly compute ignores with leading "/" in subdirectories.
We now optionally call fsync on loose objects, packfiles and their indexes,
loose references and packed reference files.
We can now build against OpenSSL v1.1 and against LibreSSL.
GIT_MERGE_OPTIONS_INIT now includes a setting to perform rename detection.
This aligns this structure with the default by git_merge and
git_merge_trees when NULL was provided for the options.
Improvements for reading index v4 files.
Perform additional retries for filesystem operations on Windows when files
are temporarily locked by other processes.
API additions
New family of functions to handle worktrees:
git_worktree_list() lets you look up worktrees for a repository.
git_worktree_lookup() lets you get a specific worktree.
git_worktree_open_from_repository() lets you get the associated worktree of a repository.
git_worktree_add lets you create new worktrees.
git_worktree_prune lets you remove worktrees from disk.
git_worktree_lock() and git_worktree_unlock() let you lock and unlock a worktree, respectively.
git_repository_open_from_worktree() lets you open a repository via
git_repository_head_for_worktree() lets you get the current HEAD for a
linked worktree.
git_repository_head_detached_for_worktree() lets you check whether a
linked worktree is in detached HEAD mode.
git_repository_item_path() lets you retrieve paths for various repository
files.
git_repository_commondir() lets you retrieve the common directory of a
repository.
git_branch_is_checked_out() allows you to check whether a branch is checked
out in a repository or any of its worktrees.
git_repository_submodule_cache_all() and
git_repository_submodule_cache_clear() functions allow you to prime or clear
the submodule cache of a repository.
You can disable strict hash verifications via the
GIT_OPT_ENABLE_STRICT_HASH_VERIFICATION option with git_libgit2_opts().
You can enable us calling fsync for various files inside the ".git"
directory by setting the GIT_OPT_ENABLE_FSYNC_GITDIR option with
git_libgit2_opts().
You can now enable "offset deltas" when creating packfiles and negotiating
packfiles with a remote server by setting GIT_OPT_ENABLE_OFS_DELTA option
with GIT_libgit2_opts().
You can now set the default share mode on Windows for opening files using
GIT_OPT_SET_WINDOWS_SHAREMODE option with git_libgit2_opts().
You can query the current share mode with GIT_OPT_GET_WINDOWS_SHAREMODE.
git_transport_smart_proxy_options() enables you to get the proxy options for
smart transports.
The GIT_FILTER_INIT macro and the git_filter_init function are provided
to initialize a git_filter structure.
Breaking API changes
clone_checkout_strategy has been removed from
git_submodule_update_option. The checkout strategy used to clone will
be the same strategy specified in checkout_opts.
For full changes, please refer CHANGESLOG.md file.
* libgit2 v0.24.6 and libgit2 v0.25.1, January 9th, 2017
Includes two fixes, one performs extra sanitization for some edge cases in
the Git Smart Protocol which can lead to attempting to parse outside of the
buffer.
The second fix affects the certificate check callback. It provides a valid
parameter to indicate whether the native cryptographic library considered
the certificate to be correct. This parameter is always 1/true before these
releases leading to a possible MITM.
This does not affect you if you do not use the custom certificate callback
or if you do not take this value into account. This does affect you if you
use pygit2 or git2go regardless of whether you specify a certificate check
callback.

v0.24
-------
### Changes or improvements
* 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.
* When adding objects to the index, or when creating new tree or commit
objects, the inputs are validated to ensure that the dependent objects
exist and are of the correct type. This object validation can be
disabled with the GIT_OPT_ENABLE_STRICT_OBJECT_CREATION option.
* The WinHTTP transport's handling of bad credentials now behaves like
the others, asking for credentials again.
### API additions
* `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.
### API removals
* No APIs were removed in this version.
### Breaking API changes
* 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.
