Provides Access to Git Repositories

Interface to the 'libgit2' library, which is a pure C implementation of the 'Git' core methods. Provides access to 'Git' repositories to extract data and running some basic 'Git' commands.


News

git2r 0.21.0

  • Added methods 'odb_blobs' and 'odb_objects' with missing repository signature. Internally, they use 'getwd' and 'discover_repository' to open a repository.

BUG FIXES

  • The bundled libgit2 source code has been reverted to libgit2 v0.26.0 (15e1193) from 14 June 2017 (same as in git2r v0.19.0) to fix memory alignment errors.

git2r 0.20.0

IMPROVEMENTS

  • Updated the bundled libgit2 source code to commit (fa8cf14) from 16 December 2017.

  • Improvements to the build configuration script.

BUG FIXES

  • Fixed the internal callback for remote host authentication from hanging indefinitely when querying an ssh-agent for credentials. Now, the callback signals an error instead of trying again if the authentication failed the first time.

git2r 0.19.0

IMPROVEMENTS

  • Updated the bundled libgit2 source code to commit (15e1193) (v0.26.0) from 14 June 2017.

  • Added 'checkout' argument to 'clone()'. Allows to control whether checkout of HEAD is performed after the clone is complete. Setting 'checkout=FALSE' has similar effect as the git command line option '--no-checkout'. Andrzej K. Oles in #282.

BUG FIXES

  • Fixed memory protection errors in the git2r C source code reported by the 'rchk' tool.

  • Added missing calls to 'R_forceSymbols' and 'R_useDynamicSymbols' in the C init function.

  • Enable argument 'all' to commit multiple modified (or deleted) files. John Blischak in #283

  • Changed the configure script to determine the architecture of the machine earlier in order to fix an unsupported architecture error encountered on CentOS (#268, #288).

git2r 0.18.0

BUG FIXES

  • This is a bug-fix release to solve an error introduced in the build configuration on mac in version 0.17.0. The package failed with 'unable to load shared object', see issue #267.

git2r 0.17.0

IMPROVEMENTS

  • Updated the bundled libgit2 source code to commit (6b0510e) from 20 December 2016.

  • Static linking of LibSSH2 on mac to support redistributable binary package with SSH transport enabled. Version 1.8.0 of LibSSH2 is downloaded and built from 'https://www.libssh2.org/download/'.

git2r 0.16.0

IMPROVEMENTS

  • Updated libgit2 source code to commit (6b0510e) from 17 November 2016.

  • Add the option 'all_untracked' to the 'status' method to show individual files in untracked directories if the 'untracked' option is TRUE.

  • Add the 'tag_delete' method to delete an existing tag reference.

  • Update build configuration to support OpenSSL 1.1.0.

  • If the the 'getPass' package is installed the 'cred_ssh_key' method to create a new passphrase-protected ssh key credential object will call the 'getPass::getPass()' method if the private key is passphrase protected to allow for interactive input of the passphrase. The 'getPass' package is a suggested package. (Peter Meissner in PR #254)

  • Add 'path' argument to the 'reset' method to enable path-specific unstage, i.e. resets the index entries for all paths to their state at HEAD

BUG FIXES

  • Build configuration: use portable string equality comparison operator. This fixes the build e.g. for those without Bash as /bin/sh. (Sander Maijers in PR #243).

git2r 0.15.0

IMPROVEMENTS

  • Build configuration: 'pkg-config' is now used to find 'libssl', if possible (Elias Pipping in PR #231).

  • Added a method to coerce a 'git_commit' object to a 'data.frame'.

  • Added the method 'is_branch' to check if an object is a 'git_branch'.

BUG FIXES

  • Build configuration: fixed installation with parallel make (Kirill Müller in PR #228).

git2r 0.14.0

IMPROVEMENTS

  • Updated libgit2 source code to commit (785d8c48) from 2016-03-04. This is release v0.24.0 of libgit2.

  • Refactoring of the build scripts.

  • Added a check that the configuration key is valid when setting a configuration variable and output a warning if the key is invalid.

  • The status method now prints "working directory clean" instead of nothing when the working directory is clean.

  • Added the 'refspec' argument to the 'fetch' method to specify the refs to fetch and which local refs to update.

  • Added a workaround to the 'commit' method to list commits in a shallow clone since the libgit2 library does not yet support this.

git2r 0.13.1

BUG FIXES

  • This is a bug-fix release to solve problems introduced in version 0.12.1:

    • The bundled libgit2 source code has been reverted to commit (98f7bd2) from 2015-08-05 (same as in v0.11.0) to fix memory alignment errors (clang-UBSAN and gcc-UBSAN).

    • OpenSSL is now used again on OS X to provide the cryptographic support for HTTPS connections to fix a significant compiler warning (arithmetic on a pointer to void is a GNU extension [-Wpointer-arith]) on r-devel-osx-x86_64-clang.

    • Several fixes to the build configuration on non-Windows platforms.

git2r 0.12.1

  • Add 'remote_ls' method to list references in a remote repository akin to the git ls-remote command.

  • Add 'remote_set_url' method to set the remote's url in the configuration.

  • Add 'cred_token' S4 class to hold the name of the environmental variable with the secret. Default value for the name is GITHUB_PAT.

  • Add 'ceiling' argument to 'discover_repository' method to prevent search from walking up the parent directories.

CHANGES

  • Improvments to the cred_* functions documentation.

  • Add the following default arguments to the 'cred_ssh_key' method: publickey = '~/.ssh/id_rsa.pub' and privatekey = '~/.ssh/id_rsa'

  • On OSX, cascade CPPFLAGS and LDFLAGS to libssh2 build to allow libssh2 to be built against a user-installed openssl, discovered by configure or from R's Makeconf. Necessary to build on OS X ≥ 10.11

  • On OS X, SecureTransport is now used to provide the cryptographic support for HTTPS connections insead of OpenSSL.

  • The search for libssh2 during configuration (non Windows) is now done via pkg-config.

  • Update OpenSSL on Windows to v1.0.2d

  • Update libgit2 source code to commit (3f5877d) from 2015-11-12.

  • Add name of branch to each item in branch_list.

  • Add name of tag to each item in tags list.

  • Add S4 class 'cred_env' to pass credentials in environment variables.

  • SSH transport on Windows. This requires 'LibSSH2' and 'OpenSSL'. These two libraries are downloaded from 'https://github.com/rwinlib' during configuration of the package.

  • Static linking of LibSSH2 on OSX to support redistributable binary package with SSH transport enabled. Version 1.6.0 of LibSSH2 is downloaded and built from 'https://github.com/libssh2/libssh2'.

IMPROVEMENTS

  • Better summary output from S4 classes 'git_commit' and 'git_repository'.

  • Updated libgit2 source code to commit (98f7bd2) from 2015-08-05.

BUG FIXES

  • Add imports to DESCRIPTION to fix CRAN notes.

  • Fix plot function to use the repository argument 'x'

  • Changed configuration to raise error if the OpenSSL library is not found on non-Windows systems.

  • Changed configuration to raise error if the iconv library is not found on OSX.

  • Removed print of the configuration in the config method. Changed to return S3 class git_config.
