 # GDNative Based Git Plugin for Godot Version Control Editor Plugin
-Implements the proxy end-points for the `EditorVCSInterface` API in the Godot Engine Editor. Uses [libgit2](https://libgit2.org) at its backend to simulate Git in code.
+
+Git implementation of the Godot Engine VCS interface in Godot. We use [libgit2](https://libgit2.org) as our backend to simulate Git in code.
+
+> Planned for the upcoming version of Godot. Look for other branches for support in other Godot releases.
 
 ## Installation Instructions
 
- 1. Plugin binary releases for Linux & Windows are here: <https://github.com/godotengine/godot-git-plugin/releases>
- 2. Installation instructions are here: https://github.com/godotengine/godot-git-plugin/wiki
+ 1. Grab the platform binaries here: <https://github.com/godotengine/godot-git-plugin/releases>
+ 2. Then read the installation instructions: https://github.com/godotengine/godot-git-plugin/wiki
 
 ## Build Instructions
 
-> Replace `Release` with `Debug` for a debug build.
+### Pre-requisites
+
+Required build tools:
+
+* [CMake](https://cmake.org/download/) (v3.5.1+)
+* [SCons](https://scons.org/pages/download.html) (v3.0.1+)
 
 ### Windows
+
+> MSVC is our recommended compiler for Windows
+
 1. Load the x64 command prompt: `x64 Native Tools Command Prompt for VS 20XX`.
-2. Run `build_libs.bat Release`.
-3. Run `scons platform=windows target=release`
+2. Run ```build_libs.bat Release```.
+3. Run ```scons platform=windows target=release```
 
 ### Linux
-1. Prepare script for execution: `chmod 755 build_libs.sh`
+
+> G++ is our recommended compiler for Linux
+
+1. Prepare script for execution: ```chmod 755 build_libs.sh```
 2. Run ```. ./build_libs.sh Release```.
-3. Run `scons platform=x11 target=release`.
+3. Run ```scons platform=x11 target=release```.
+
+### MacOS
+
+> G++ and Clang++ are our recommended compilers for MacOS
+
+1. Prepare script for execution: ```chmod 755 build_libs_mac.sh```
+2. Run ```. ./build_libs_mac.sh Release```.
+3. Run ```scons platform=osx target=release```.
+
+#### Debug build
+
+Replace `Release` with `Debug` and `release` with `debug` in the above instructions for a debug build. You will also have to do the same in the paths mentioned in `demo/git_api.gdnlib` before opening the demo project in Godot.

----------
+v1.0
+----
+
+This is release v1.0 "Luftschloss", which is the first stabe release of
+libgit2. The API will stay compatible across all releases of the same major
+version. This release includes bugfixes only and supersedes v0.99, which will
+stop being maintained. Both v0.27 and v0.28 stay supported in accordance with
+our release policy.
+
+### Changes or improvements
+
+- CMake was converted to make use of the GNUInstallDirs module for both our
+  pkgconfig and install targets in favor of our custom build options
+  `BIN_INSTALL_DIR`, `LIB_INSTALL_DIR` and `INCLUDE_INSTALL_DIR`. Instead, you
+  can now use CMakes standard variables `CMAKE_INSTALL_BINDIR`,
+  `CMAKE_INSTALL_LIBDIR` and `CMAKE_INSTALL_INCLUDEDIR`.
+
+- Some CMake build options accepted either a specific value or a boolean value
+  to disable the option altogether or use automatic detection. We only accepted
+  "ON" or "OFF", but none of the other values CMake recognizes as boolean. This
+  was aligned with CMake's understanding of booleans.
+
+- The installed pkgconfig file contained incorrect values for both `libdir` and
+  `includedir` variables.
+
+- If using pcre2 for regular expressions, then we incorrectly added "pcre2"
+  instead of "pcre2-8" to our pkgconfig dependencies, which was corrected.
+
+- Fixed building the bundled ntlmclient dependency on FreeBSD, OpenBSD and
+  SunOS.
+
+- When writing symlinks on Windows, we incorrectly handled relative symlink
+  targets, which was corrected.
+
+- When using the HTTP protocol via macOS' SecureTransport implementation, reads
+  could stall at the end of the session and only continue after a timeout of 60
+  seconds was reached.
+
+- The filesystem-based reference callback didn't corectly initialize the backend
+  version.
+
+- A segmentation fault was fixed when calling `git_blame_buffer()` for files
+  that were modified and added to the index.
+
+- A backwards-incompatible change was introduced when we moved some structures
+  from "git2/credentials.h" into "git2/sys/credentials.h". This was fixed in the
+  case where you do not use hard deprecation.
+
+- Improved error handling in various places.
+
+
+v0.99
+-----
+
+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
+
+- CVE-2019-1348: the fast-import stream command "feature
+  export-marks=path" allows writing to arbitrary file paths. As
+  libgit2 does not offer any interface for fast-import, it is not
+  susceptible to this vulnerability.
+
+- CVE-2019-1349: by using NTFS 8.3 short names, backslashes or
+  alternate filesystreams, it is possible to cause submodules to
+  be written into pre-existing directories during a recursive
+  clone using git. As libgit2 rejects cloning into non-empty
+  directories by default, it is not susceptible to this
+  vulnerability.
+
+- CVE-2019-1350: recursive clones may lead to arbitrary remote
+  code executing due to improper quoting of command line
+  arguments. As libgit2 uses libssh2, which does not require us
+  to perform command line parsing, it is not susceptible to this
+  vulnerability.
+
+- CVE-2019-1351: Windows provides the ability to substitute
+  drive letters with arbitrary letters, including multi-byte
+  Unicode letters. To fix any potential issues arising from
+  interpreting such paths as relative paths, we have extended
+  detection of DOS drive prefixes to accomodate for such cases.
+
+- CVE-2019-1352: by using NTFS-style alternative file streams for
+  the ".git" directory, it is possible to overwrite parts of the
+  repository. While this has been fixed in the past for Windows,
+  the same vulnerability may also exist on other systems that
+  write to NTFS filesystems. We now reject any paths starting
+  with ".git:" on all systems.
+
+- CVE-2019-1353: by using NTFS-style 8.3 short names, it was
+  possible to write to the ".git" directory and thus overwrite
+  parts of the repository, leading to possible remote code
+  execution. While this problem was already fixed in the past for
+  Windows, other systems accessing NTFS filesystems are
+  vulnerable to this issue too. We now enable NTFS protecions by
+  default on all systems to fix this attack vector.
+
+- CVE-2019-1354: on Windows, backslashes are not a valid part of
+  a filename but are instead interpreted as directory separators.
+  As other platforms allowed to use such paths, it was possible
+  to write such invalid entries into a Git repository and was
+  thus an attack vector to write into the ".git" dierctory. We
+  now reject any entries starting with ".git\" on all systems.
+
+- CVE-2019-1387: it is possible to let a submodule's git
+  directory point into a sibling's submodule directory, which may
+  result in overwriting parts of the Git repository and thus lead
+  to arbitrary command execution. As libgit2 doesn't provide any
+  way to do submodule clones natively, it is not susceptible to
+  this vulnerability. Users of libgit2 that have implemented
+  recursive submodule clones manually are encouraged to review
+  their implementation for this vulnerability.
+
+### Breaking API changes
+
+* 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.
