* Add external API to access detailed commit attributesVicent Marti2010-07-151-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add support for tree objects in revision poolsVicent Marti2010-07-151-0/+4
| | | | | | | | | | Commits now store pointers to their tree objects. Tree objects now work as separate git_revpool_object entities. Tree objects can be loaded and parsed inedependently from commits. Signed-off-by: Vicent Marti <tanoku@gmail.com>
* Changed revpool's object table to support arbitrary objectsVicent Marti2010-07-151-0/+1
| | | | | | | | | | | | git_revpool_object now has a type identifier for each object type in a revpool (commits, trees, blobs, etc). Trees can now be stored in the revision pool. git_revpool_tableit now supports filtering objects by their type when iterating through the object table. Signed-off-by: Vicent Marti <tanoku@gmail.com>

* Add topological sorting and new insertion methods for commit lists.Vicent Marti2010-06-021-3/+9
| | | | | | | | | | | | 'git_commit_list_toposort()' and 'git_commit_list_timesort()' now sort a commit list by topological and time order respectively. Both sorts are stable and in place. 'git_commit_list_append' has been replaced by 'git_commit_list_push_back' and 'git_commit_list_push_front'. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Added sort method for commit lists.Vicent Marti2010-06-021-0/+1
| | | | | | | Fixed bug when parsing time headers from commits. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Add 'git_revpool_object' and 'git_revpool_table' structures.Vicent Marti2010-06-021-2/+3
| | | | | | | | | | | | | | All the objects which will will be eventually transversable from a revision pool (commits, trees, etc) now inherit from the 'git_revpool_object' structure which identifies them with their own OID. Furthermore, the 'git_revpool_table' and related functions have been added, which allow for constant time lookup (hash table) of the loaded revpool objects based on their OID.

* Changed 'git_commit_list' from a linked list to a doubly-linked list.Vicent Marti2010-06-021-7/+19
| | | | | | | Changed 'git_commit' to use bit fields instead of flags. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Add arbritrary ordering revision walking.Vicent Marti2010-06-021-0/+1
| | | | | | | | The 'gitrp_next()' method now correctly does a revision walking of all the pushed revisions in arbritary ordering. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Split git_commit_lookup into separate functions.Vicent Marti2010-06-021-0/+2
| | | | | | | | | | | git_commit_lookup() now creates commit references without loading them from the ODB. git_commit_parse() creates a commit reference, loads it and parses it from the ODB. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Add commit parents to parsed commits and commit lists to the revpool.Vicent Marti2010-06-021-0/+11
| | | | | | | | | | | | | | | | | | Basic support for iterating the revpool. The following functions of the revwalk API have been partially implemented: void gitrp_reset(git_revpool *pool); void gitrp_push(git_revpool *pool, git_commit *commit); void gitrp_prepare_walk(git_revpool *pool); git_commit *gitrp_next(git_revpool *pool); Parsed commits' parents are now also parsed and stored in a "git_commit_list" structure (linked list).

* Add basic functionality for commit lookup/parsingVicent Marti2010-06-021-0/+9
| | | | | | | | | | | | | | | | | | | | The external API function "git_commit_parse" has been renamed to "git_commit_lookup" and has been partially implemented with support for loading commits straight from the ODB. It still lacks the functionality to lookup cached commits in the revpool and to resolve tags to commits. The following internal functions have been partially implemented: int git_commit__parse_buffer(...); int git_commit__parse_time(...); int git_commit__parse_oid(...); Commits are now fully parsed but the generated parent and tree references are not handled yet.

Using it in the first place means something's wrong. This patch replaces it with an internal header which carries the previously "protected" code instead. Internal source-files simply include "commit.h" and they're done. The internal header includes the public one to make sure we always use the proper prototype.
