- Update to version 0.28.0:
* Changes or improvements:
- The library is now always built with cdecl calling
conventions on Windows; the ability to build a stdcall
library has been removed.
- Reference log creation now honors
core.logallrefupdates=always.
- Fix some issues with the error-reporting in the OpenSSL
backend.
- HTTP proxy support is now builtin; libcurl is no longer used
to support proxies and is removed as a dependency.
- Certificate and credential callbacks can now return
GIT_PASSTHROUGH to decline to act; libgit2 will behave as if
there was no callback set in the first place.
- The line-ending filtering logic - when checking out files -
has been updated to match newer git (>= git 2.9) for proper
interoperability.
- Symbolic links are now supported on Windows when
core.symlinks is set to true.
- Submodules with names which attempt to perform path traversal
now have their configuration ignored. Such names were blindly
appended to the $GIT_DIR/modules and a malicious name could
lead to an attacker writing to an arbitrary location. This
matches git's handling of CVE-2018-11235.
- Object validation is now performed during tree creation in
the git_index_write_tree_to API.
- Configuration variable may now be specified on the same line
as a section header; previously this was erroneously a parser
error.
- When an HTTP server supports both NTLM and Negotiate
authentication mechanisms, we would previously fail to
authenticate with any mechanism.
- The GIT_OPT_SET_PACK_MAX_OBJECTS option can now set the
maximum number of objects allowed in a packfile being
downloaded; this can help limit the maximum memory used when
fetching from an untrusted remote.
- Line numbers in diffs loaded from patch files were not being
populated; they are now included in the results.
- The repository's index is reloaded from disk at the beginning
of git_merge operations to ensure that it is up-to-date.
- Mailmap handling APIs have been introduced, and the new
commit APIs git_commit_committer_with_mailmap and
git_commit_author_with_mailmap will use the mailmap to
resolve the committer and author information. In addition,
blame will use the mailmap given when the
GIT_BLAME_USE_MAILMAP option.
- Ignore handling for files in ignored folders would be
ignored.
- Worktrees can now be backed by bare repositories.
- Trailing spaces are supported in .gitignore files, these
spaces were previously (and erroneously) treated as part of
the pattern.
- The library can now be built with mbedTLS support for HTTPS.
- The diff status character 'T' will now be presented by the
git_diff_status_char API for diff entries that change type.
- Revision walks previously would sometimes include commits
that should have been ignored; this is corrected.
- Revision walks are now more efficient when the output is
unsorted; we now avoid walking all the way to the beginning
of history unnecessarily.
- Error-handling around index extension loading has been fixed.
We were previously always misreporting a truncated index.
* API additions:
- The index may now be iterated atomically using
git_index_iterator.
- Remote objects can now be created with extended options using
the git_remote_create_with_opts API.
- Diff objects can now be applied as changes to the working
directory, index or both, emulating the git apply command.
Additionally, git_apply_to_tree can apply those changes to a
tree object as a fully in-memory operation.
- You can now swap out memory allocators via the
GIT_OPT_SET_ALLOCATOR option with git_libgit2_opts().
- You can now ensure that functions do not discard unwritten
changes to the index via the
GIT_OPT_ENABLE_UNSAVED_INDEX_SAFETY option to
git_libgit2_opts(). This will cause functions that implicitly
re-read the index (eg, git_checkout) to fail if you have
staged changes to the index but you have not written the
index to disk. (Unless the checkout has the FORCE flag
specified.)
- At present, this defaults to off, but we intend to enable
this more broadly in the future, as a warning or error. We
encourage you to examine your code to ensure that you are not
relying on the current behavior that implicitly removes
staged changes.
- Reference specifications can be parsed from an arbitrary
string with the git_refspec_parse API.
- You can now get the name and path of worktrees using the
git_worktree_name and git_worktree_path APIs, respectively.
- The ref field has been added to git_worktree_add_options to
enable the creation of a worktree from a pre-existing branch.
- It's now possible to analyze merge relationships between any
two references, not just against HEAD, using
git_merge_analysis_for_ref.
* API removals:
- The git_buf_free API is deprecated; it has been renamed to
git_buf_dispose for consistency. The git_buf_free API will be
retained for backward compatibility for the foreseeable
future.
- The git_otype enumeration and its members are deprecated and
have been renamed for consistency. The GIT_OBJ_ enumeration
values are now prefixed with GIT_OBJECT_. The old
enumerations and macros will be retained for backward
compatibility for the foreseeable future.
- Several index-related APIs have been renamed for consistency.
The GIT_IDXENTRY_ enumeration values and macros have been
renamed to be prefixed with GIT_INDEX_ENTRY_. The
GIT_INDEXCAP enumeration values are now prefixed with
GIT_INDEX_CAPABILITY_. The old enumerations and macros will
be retained for backward compatibility for the foreseeable
future.
- The error functions and enumeration values have been renamed
for consistency. The giterr_ functions and values prefix have
been renamed to be prefixed with git_error_; similarly,
the GITERR_ constants have been renamed to be prefixed with
GIT_ERROR_. The old enumerations and macros will be retained
for backward compatibility for the foreseeable future.
* Breaking API changes:
- The default checkout strategy changed from DRY_RUN to SAFE.
- Adding a symlink as .gitmodules into the index from the
workdir or checking out such files is not allowed as this can
make a Git implementation write outside of the repository and
bypass the fsck checks for CVE-2018-11235.
- Bump sover to 28 following upstreams changes.

- libgit2 0.27.3:
* CVE-2018-10887 (bsc#1100613), CVE-2018-10888 (bsc#1100612):
Specially crafted delta object in packfiles could trigger an
integer overflow, bypassing input validation and causing the
object database to contain copies of system memory. This may
allow denial of service or, potentially, an information leak
- includes changes from 0.27.2:
* various API and correctnes fixes
* Fixes related to handling of .gitmodules
- includes changes from 0.27.1:
* CVE-2018-11235: insufficient validation of submodule names from
.gitmodules allowed writes to arbitrary paths (bsc#1095219)
* disallow .gitmodules files as symlinks.

- Update to 0.26.3:
* Fix cloning of the libgit2 project with git clone --recursive by removing an
invalid submodule from our testing data.
* Fix endianness of the port in p_getaddrinfo().
* Fix handling of negative gitignore rules with wildcards.
* Fix handling of case-insensitive negative gitignore rules.
* Fix resolving references to a tag if the reference is stored with its fully

* Fix checkout not treating worktree files as modified when only their mode has
changed.
* Fix rename detection with GIT_DIFF_FIND_RENAMES_FROM_REWRITES.
* Fixes memory handling issues when reading crafted repository index files.
The issues allow for possible denial of service due to allocation of large
memory and out-of-bound reads.
