v0.28.4
--------
v0.99
-----
This is a security release fixing the following issues:
This is v0.99 "Torschlusspanik". This will be the last minor release
before libgit2 v1.0. We expect to only respond to bugs in this release,
to stabilize it for next major release.
It contains significant refactorings, but is expected to be API-compatible
with v0.28.0.
### Changes or improvements
* When fetching from an anonymous remote using a URL with authentication
information provided in the URL (eg `https://foo:bar@example.com/repo`),
we would erroneously include the literal URL in the FETCH_HEAD file.
We now remove that to match git's behavior.
* Some credential structures, enums and values have been renamed:
`git_cred` is now `git_credential`. `git_credtype_t` is now
`git_credential_t`. Functions and types beginning with
`git_cred_` now begin with `git_credential`, and constants beginning
with `GIT_CREDTYPE` now begin with `GIT_CREDENTIAL`. The former names
are deprecated.
* Several function signatures have been changed to return an `int` to
indicate error conditions. We encourage you to check them for errors
in the standard way.
* `git_attr_cache_flush`
* `git_error_set_str`
* `git_index_name_clear`
* `git_index_reuc_clear`
* `git_libgit2_version`
* `git_mempack_reset`
* `git_oid_cpy`
* `git_oid_fmt`
* `git_oid_fromraw`
* `git_oid_nfmt`
* `git_oid_pathfmt`
* `git_remote_stop`
* `git_remote_disconnect`
* `git_repository__cleanup`
* `git_repository_set_config`
* `git_repository_set_index`
* `git_repository_set_odb`
* `git_repository_set_refdb`
* `git_revwalk_reset`
* `git_revwalk_simplify_first_parent`
* `git_revwalk_sorting`
* `git_treebuilder_clear`
* `git_treebuilder_filter`
* The NTLM and Negotiate authentication mechanisms are now supported when
talking to git implementations hosted on Apache or nginx servers.
* The `HEAD` symbolic reference can no longer be deleted.
* `git_merge_driver_source_repo` no longer returns a `const git_repository *`,
it now returns a non-`const` `git_repository *`.
* Relative symbolic links are now supported on Windows when `core.symlinks`
is enabled.
* Servers that provide query parameters with a redirect are now supported.
* `git_submodule_sync` will now resolve relative URLs.
* When creating git endpoint URLs, double-slashes are no longer used when
the given git URL has a trailing slash.
* On Windows, a `DllMain` function is no longer included and thread-local
storage has moved to fiber-local storage in order to prevent race
conditions during shutdown.
* The tracing mechanism (`GIT_TRACE`) is now enabled by default and does
not need to be explicitly enabled in CMake.
* The size of Git objects is now represented by `git_object_size_t`
instead of `off_t`.
* Binary patches without data can now be parsed.
* A configuration snapshot can now be created from another configuration
snapshot, not just a "true" configuration object.
* The `git_commit_with_signature` API will now ensure that referenced
objects exist in the object database.
* Stash messages containing newlines will now be replaced with spaces;
they will no longer be (erroneously) written to the repository.
* `git_commit_create_with_signature` now verifies the commit information
to ensure that it points to a valid tree and valid parents.
* `git_apply` has an option `GIT_APPLY_CHECK` that will only do a dry-run.
The index and working directory will remain unmodified, and application
will report if it would have worked.
* Patches produced by Mercurial (those that lack some git extended headers)
can now be parsed and applied.
* Reference locks are obeyed correctly on POSIX platforms, instead of
being removed.
* Patches with empty new files can now be read and applied.
* `git_apply_to_tree` can now correctly apply patches that add new files.
* The program data configuration on Windows (`C:\ProgramData\Git\config`)
must be owned by an administrator, a system account or the current user
to be read.
* `git_blob_filtered_content` is now deprecated in favor of `git_blob_filter`.
* Configuration files can now be included conditionally using the
`onbranch` conditional.
* Checkout can now properly create and remove symbolic links to directories
on Windows.
* Stash no longer recomputes trees when committing a worktree, for
improved performance.
* Repository templates can now include a `HEAD` file to default the
initial default branch.
* Some configuration structures, enums and values have been renamed:
`git_cvar_map` is now `git_configmap`, `git_cvar_t` is now
`git_configmap_t`, `GIT_CVAR_FALSE` is now `GIT_CONFIGMAP_FALSE`,
`GIT_CVAR_TRUE` is now `GIT_CONFIGMAP_TRUE`, `GIT_CVAR_INT32` is now
`GIT_CONFIGMAP_INT32`, and `GIT_CVAR_STRING` is now `GIT_CONFIGMAP_STRING`.
The former names are deprecated.
* Repositories can now be created at the root of a Windows drive.
* Configuration lookups are now more efficiently cached.
* `git_commit_create_with_signature` now supports a `NULL` signature,
which will create a commit without adding a signature.
* When a repository lacks an `info` "common directory", we will no
longer erroneously return `GIT_ENOTFOUND` for all attribute lookups.
* Several attribute macros have been renamed: `GIT_ATTR_TRUE` is now
`GIT_ATTR_IS_TRUE`, `GIT_ATTR_FALSE` is now `GIT_ATTR_IS_FALSE`,
`GIT_ATTR_UNSPECIFIED` is now `GIT_ATTR_IS_UNSPECIFIED`. The
attribute enum `git_attr_t` is now `git_attr_value_t` and its
values have been renamed: `GIT_ATTR_UNSPECIFIED_T` is now
`GIT_ATTR_VALUE_UNSPECIFIED`, `GIT_ATTR_TRUE_T` is now
`GIT_ATTR_VALUE_TRUE`, `GIT_ATTR_FALSE_T` is now `GIT_ATTR_VALUE_FALSE`,
and `GIT_ATTR_VALUE_T` is now `GIT_ATTR_VALUE_STRING`. The
former names are deprecated.
* `git_object__size` is now `git_object_size`. The former name is
deprecated.
* `git_tag_create_frombuffer` is now `git_tag_create_from_buffer`. The
former name is deprecated.
* Several blob creation functions have been renamed:
`git_blob_create_frombuffer` is now named `git_blob_create_from_buffer`,
`git_blob_create_fromdisk` is now named `git_blob_create_from_disk`,
`git_blob_create_fromworkdir` is now named `git_blob_create_from_workdir`,
`git_blob_create_fromstream` is now named `git_blob_create_from_stream`,
and `git_blob_create_fromstream_commit` is now named
`git_blob_create_from_stream_commit`. The former names are deprecated.
* The function `git_oid_iszero` is now named `git_oid_is_zero`. The
former name is deprecated.
* Pattern matching is now done using `wildmatch` instead of `fnmatch`
for compatibility with git.
* The option initialization functions suffixed by `init_options` are now
suffixed with `options_init`. (For example, `git_checkout_init_options`
is now `git_checkout_options_init`.) The former names are deprecated.
* NTLM2 authentication is now supported on non-Windows platforms.
* The `git_cred_sign_callback` callback is now named `git_cred_sign_cb`.
The `git_cred_ssh_interactive_callback` callback is now named
`git_cred_ssh_interactive_cb`.
* Ignore files now:
* honor escaped trailing whitespace.
* do not incorrectly negate sibling paths of a negated pattern.
* honor rules that stop ignoring files after a wildcard
* Attribute files now:
* honor leading and trailing whitespace.
* treat paths beginning with `\` as absolute only on Windows.
* properly handle escaped characters.
* stop reading macros defined in subdirectories
* The C locale is now correctly used when parsing regular expressions.
* The system PCRE2 or PCRE regular expression libraries are now used
when `regcomp_l` is not available on the system. If none of these
are available on the system, an included version of PCRE is used.
* Wildcards in reference specifications are now supported beyond simply
a bare wildcard (`*`) for compatibility with git.
* When `git_ignore_path_is_ignored` is provided a path with a trailing
slash (eg, `dir/`), it will now treat it as a directory for the
purposes of ignore matching.
* Patches that add or remove a file with a space in the path can now
be correctly parsed.
* The `git_remote_completion_type` type is now `git_remote_completion_t`.
The former name is deprecated.
* The `git_odb_backend_malloc` is now `git_odb_backend_data_alloc`. The
former name is deprecated.
* The `git_transfer_progress_cb` callback is now `git_indexer_progress_cb`
and the `git_transfer_progress` structure is now `git_indexer_progress`.
The former names are deprecated.
* The example projects are now contained in a single `lg2` executable
for ease of use.
* libgit2 now correctly handles more URLs, such as
`http://example.com:/repo.git` (colon but no port),
`http://example.com` (no path),
and `http://example.com:8080/` (path is /, nonstandard port).
* A carefully constructed commit object with a very large number
of parents may lead to potential out-of-bounds writes or
potential denial of service.
* The ProgramData configuration file is always read for compatibility
with Git for Windows and Portable Git installations. The ProgramData
location is not necessarily writable only by administrators, so we
now ensure that the configuration file is owned by the administrator
or the current user.
### API additions
* The SSH host key now supports SHA-256 when `GIT_CERT_SSH_SHA256` is set.
* The diff format option `GIT_DIFF_FORMAT_PATCH_ID` can now be used to
emit an output like `git patch-id`.
* The `git_apply_options_init` function will initialize a
`git_apply_options` structure.
* The remote callbacks structure adds a `git_url_resolve_cb` callback
that is invoked when connecting to a server, so that applications
may edit or replace the URL before connection.
* The information about the original `HEAD` in a rebase operation is
available with `git_rebase_orig_head_name`. Its ID is available with
`git_rebase_orig_head_id`. The `onto` reference name is available with
`git_rebase_onto_name` and its ID is available with `git_rebase_onto_id`.
* ODB backends can now free backend data when an error occurs during its
backend data creation using `git_odb_backend_data_free`.
* Options may be specified to `git_repository_foreach_head` to control
its behavior: `GIT_REPOSITORY_FOREACH_HEAD_SKIP_REPO` will not skip
the main repository's HEAD reference, while
`GIT_REPOSITORY_FOREACH_HEAD_SKIP_WORKTREES` will now skip the
worktree HEAD references.
* The `GIT_OPT_DISABLE_PACK_KEEP_FILE_CHECKS` option can be specified to
`git_libgit2_opts()` to avoid looking for `.keep` files that correspond
to packfiles. This setting can improve performance when packfiles are
stored on high-latency filesystems like network filesystems.
* Blobs can now be filtered with `git_blob_filter`, which allows for
options to be set with `git_blob_filter_options`, including
`GIT_FILTER_NO_SYSTEM_ATTRIBUTES` to disable filtering with system-level
attributes in `/etc/gitattributes` and `GIT_ATTR_CHECK_INCLUDE_HEAD` to
enable filtering with `.gitattributes` files in the HEAD revision.
### API removals
* The unused `git_headlist_cb` function declaration was removed.
* The unused `git_time_monotonic` API is removed.
* The erroneously exported `inttypes.h` header was removed.
# Security Fixes

export-marks=path" allows writing to arbitrary file paths. As
@ -58,54 +342,86 @@ This is a security release fixing the following issues:
recursive submodule clones manually are encouraged to review
their implementation for this vulnerability.
v0.28.3
-------
### Breaking API changes
This is a security release fixing the following issues:
* The "private" implementation details of the `git_cred` structure have been
moved to a dedicated `git2/sys/cred.h` header, to clarify that the underlying
structures are only provided for custom transport implementers.
The breaking change is that the `username` member of the underlying struct
is now hidden, and a new `git_cred_get_username` function has been provided.
* A carefully constructed commit object with a very large number
of parents may lead to potential out-of-bounds writes or
potential denial of service.
### Breaking CMake configuration changes
* The ProgramData configuration file is always read for compatibility
with Git for Windows and Portable Git installations. The ProgramData
location is not necessarily writable only by administrators, so we
now ensure that the configuration file is owned by the administrator
or the current user.
* The CMake option to use a system http-parser library, instead of the
bundled dependency, has changed. This is due to a deficiency in
http-parser that we have fixed in our implementation. The bundled
library is now the default, but if you wish to force the use of the
system http-parser implementation despite incompatibilities, you can
specify `-DUSE_HTTP_PARSER=system` to CMake.
v0.28.2
-------
* The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been
streamlined. The detection was moved to a new `USE_SHA1`, modeled after
`USE_HTTPS`, which takes the values "CollisionDetection/Backend/Generic", to
better match how the "hashing backend" is selected, the default (ON) being
"CollisionDetection". If you were using `SHA1_BACKEND` previously, you'll
need to check the value you've used, or switch to the autodetection.
This is a bugfix release with the following changes:
### Authors
* Fix include directory ordering when using bundled dependencies.
The following individuals provided changes that were included in this
release:
* Fix infinite loop when searching for a non-existing repository with
Windows-style paths including drive prefixes.
* Fix paths with a trailing "/" not always being treated as
directories when computing ignores.
* Fix false negatives when computing ignores where ignore rules
that are a prefix to a negative ignore rule exist.
* Fix patches with CRLF line endings not being parsed correctly.
* Fix segfault when parsing patches with file addition (deletion)
where the added (deleted) file name contains a space.
* Fix assertion failure when trying to write to a non-existent
locked configuration file.
v0.28.1
-------
This is a bugfix release with the following change:
* The deprecated functions (`git_buf_free` and the `giterr_` family of
functions) are now exported properly. In the v0.28 release, they were
not given the correct external attributes and they did not have the
correct linkage visibility in the v0.28 library.

* Commit signing callback.

* The callback will be called with the commit content, giving a user an
* opportunity to sign the commit content. The signature_field
* buf may be left empty to specify the default field "gpgsig".
*
* Signatures can take the form of any string, and can be created on an arbitrary
* header field. Signatures are most commonly used for verifying authorship of a
* commit using GPG or a similar cryptographically secure signing algorithm.
* See https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work for more
* details.
*
* When the callback:
* - returns GIT_PASSTHROUGH, no signature will be added to the commit.
* - returns < 0, commit creation will be aborted.
* - returns GIT_OK, the signature parameter is expected to be filled.
