  Add external API to access detailed commit attributes The following new external methods have been added: GIT_EXTERN(const char *) git_commit_message_short(git_commit *commit); GIT_EXTERN(const char *) git_commit_message(git_commit *commit); GIT_EXTERN(time_t) git_commit_time(git_commit *commit); GIT_EXTERN(const git_commit_person *) git_commit_committer(git_commit *commit); GIT_EXTERN(const git_commit_person *) git_commit_author(git_commit *commit); GIT_EXTERN(const git_tree *) git_commit_tree(git_commit *commit); A new structure, git_commit_person has been added to represent a commit's author or committer. The parsing of a commit has been split in two phases. When adding a commit to the revision pool: - the commit's ODB object is opened - its raw contents are parsed for commit TIME, PARENTS and TREE (the minimal amount of data required to traverse the pool) - the commit's ODB object is closed When querying for extended information on a commit: - the commit's ODB object is reopened - its raw contents are parsed for the requested information - the commit's ODB object remains open to handle additional queries New unit tests have been added for the new functionality: In t0401-parse: parse_person_test In t0402-details: query_details_test Signed-off-by: Vicent Marti <tanoku@gmail.com>
