Vicent Marti 3315782c 2010-08-08T14:12:17 Redesigned the walking/object lookup interface The old 'git_revpool' object has been removed and split into two distinct objects with separate functionality, in order to have separate methods for object management and object walking. * A new object 'git_repository' does the high-level management of a repository's objects (commits, trees, tags, etc) on top of a 'git_odb'. Eventually, it will also manage other repository attributes (e.g. tag resolution, references, etc). See: src/git/repository.h * A new external method 'git_repository_lookup(repo, oid, type)' has been added to the 'git_repository' API. All object lookups (git_XXX_lookup()) are now wrappers to this method, and duplicated code has been removed. The method does automatic type checking and returns a generic 'git_revpool_object' that can be cast to any specific object. See: src/git/repository.h * The external methods for object parsing of repository objects (git_XXX_parse()) have been removed. Loading objects from the repository is now managed through the 'lookup' functions. These objects are loaded with minimal information, and the relevant parsing is done automatically when the user requests any of the parsed attributes through accessor methods. An attribute has been added to 'git_repository' in order to force the parsing of all the repository objects immediately after lookup. See: src/git/commit.h See: src/git/tag.h See: src/git/tree.h * The previous walking functionality of the revpool is now found in 'git_revwalk', which does the actual revision walking on a repository; the attributes when walking through commits in a database have been decoupled from the actual commit objects. This increases performance when accessing commits during the walk and allows to have several 'git_revwalk' instances working at the same time on top of the same repository, without having to load commits in memory several times. See: src/git/revwalk.h * The old 'git_revpool_table' has been renamed to 'git_hashtable' and now works as a generic hashtable with support for any kind of object and custom hash functions. See: src/hashtable.h * All the relevant unit tests have been updated, renamed and grouped accordingly. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 364788e1 2010-08-07T00:59:58 Refactor parsing methods The 'parse_oid' and 'parse_person' methods which were used by the commit parser are now global so they can be used when parsing other objects. The 'git_commit_person' struct has been changed to a generic 'git_person'. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti d8603ed9 2010-07-10T16:51:15 Add parsing of tree file contents. The basic information (pointed trees and blobs) of each tree object in a revision pool can now be parsed and queried. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 52f2390b 2010-07-07T14:56:05 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>
Vicent Marti 225fe215 2010-06-18T13:06:34 Add support for tree objects in revision pools 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>
Vicent Marti 40721f6b 2010-07-10T11:50:16 Changed revpool's object table to support arbitrary objects 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>
Vicent Marti 088a731f 2010-06-09T14:54:22 Fixed memory leaks in test suite Created commit objects in t0401-parse weren't being freed properly. Updated the API documentation to note that commit objects are owned by the revision pool and should not be freed manually. The parents list of each commit was being freed twice after each test.

Ramsay Jones 28f98329 2010-06-01T19:37:10 Fix inconsistent definition of off_t on Linux In order to avoid inconsistent definitions of type off_t, all compilation units should include the "common.h" header file before certain system headers (those which directly or indirectly lead to the definition of off_t). The "common.h" header contains the definition of _FILE_OFFSET_BITS to select 64-bit file offsets. The symptom of this inconsistency, while compiling with -Wextra, is the following warning: In file included from src/common.h:50, from src/commit.c:28: src/util.h: In function git__is_sizet: src/util.h:41: warning: comparison between signed and unsigned In order to fix the problem, we simply remove the #include <time.h> statement at the head of src/commit.c. Note that src/commit.h also includes <time.h>. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>
Ramsay Jones ee1765e5 2010-06-01T19:32:41 Fix sparse warnings: "Using plain integer as NULL pointer" In order to suppress this warning, we could simply replace the constant 0 with NULL.

Vicent Marti 655d381a 2010-05-23T16:51:31 Add topological sorting and new insertion methods for commit lists. '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>

Vicent Marti 42281e00 2010-05-16T01:52:31 Add unit tests for Commit parsing A few initial tests for commit parsing: "parse_buffer_test" tests git_commit__parse_buffer() with several malformed commit messages and a few corner cases which should pass. "parse_oid_test" tests git_commit__parse_oid() with several malformed commit lines containing broken SHA1 OIDs.

Vicent Marti 417f0abc 2010-05-14T18:44:49 Add basic functionality for commit lookup/parsing 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.

Vicent Marti c5696427 2010-05-22T23:21:10 Add 'git_revpool_object' and 'git_revpool_table' structures. 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.

Vicent Marti 36b7cdb6 2010-05-22T18:15:42 Changed 'git_commit_list' from a linked list to a doubly-linked list. 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>
Vicent Marti 1a895dd7 2010-05-22T14:32:59 Add arbritrary ordering revision walking. 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>
Vicent Marti 8add0153 2010-05-21T02:35:40 Split git_commit_lookup into separate functions. 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.

Vicent Marti 08d5d000 2010-05-18T20:55:19 Add commit parents to parsed commits and commit lists to the revpool. 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).

Shawn O. Pearce 64a47c01 2008-12-30T23:21:36 Wrap malloc and friends and report out of memory as GIT_ENOMEM We now forbid direct use of malloc, strdup or calloc within the library and instead use wrapper functions git__malloc, etc. to invoke the underlying library malloc and set git_errno to a no memory error code if the allocation fails. In the future once we have pack objects in memory we are likely to enhance these routines with garbage collection logic to purge cached pack data when allocations fail. Because the size of the function will grow somewhat large, we don't want to mark them for inline as gcc tends to aggressively inline, creating larger than expected executables.

Andreas Ericsson 4f0adcd0 2008-11-18T21:28:55 Get rid of GIT__PRIVATE macro 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. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
