Vicent Marti 6fd195d7 2010-11-02T18:42:42 Change git_repository initialization to use a path The constructor to git_repository is now called 'git_repository_open(path)' and takes a path to a git repository instead of an existing ODB object. Unit tests have been updated accordingly and the two test repositories have been merged into one. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti a13bc8e7 2010-10-29T02:22:38 Add getter methods for object owners You can know access the owning repository of any existing object, or the repository on which a revision walker is working on. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti adc0327a 2010-10-29T00:44:15 Add git_odb_read_header method to the ODB As requested, git_odb_read_header looks up an object on the ODB, but loads only the header information (type & size) without loading any of the actual file contents in memory. It is significantly faster than doing a git_odb_read if you only need an object's information and not its contents. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 58519018 2010-10-28T02:07:18 Fix internal memory management on the library String mememory is now managed in a much more sane manner. Fixes include: - git_person email and name is no longer limited to 64 characters - git_tree_entry filename is no longer limited to 255 characters - raw objects are properly opened & closed the minimum amount of times required for parsing - unit tests no longer leak - removed 5 other misc memory leaks as reported by Valgrind - tree writeback no longer segfaults on rare ocassions The git_person struct is no longer public. It is now managed by the library, and getter methods are in place to access its internal attributes. Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti e4def81a 2010-10-08T13:52:17 Fix issue 3 (memory corruption resize_tree_array) The tree array wasn't being initialized when instantiating a tree object in memory instead of loading it from disk. New unit tests added to check for the problem. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti ec25391d 2010-10-07T00:20:08 Add write-back support for Tag files Tag files can now be created and modified in-memory (all the setter methods have been implemented), and written back to disk using the generic git_object_write() method. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 2a884588 2010-09-21T17:17:10 Add write-back support for git_tree All the setter methods for git_tree have been added, including the setters for attributes on each git_tree_entry and methods to add/remove entries of the tree. Modified trees and trees created in-memory from scratch can be written back to the repository using git_object_write(). Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti d45b4a9a 2010-09-20T21:39:11 Add support for in-memory objects All repository objects can now be created from scratch in memory using either the git_object_new() method, or the corresponding git_XXX_new() for each object. So far, only git_commits can be written back to disk once created in memory. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 0c3596f1 2010-09-20T01:57:53 Add setter methods & write support for git_commit All the required git_commit_set_XXX methods have been implemented; all the attributes of a commit object can now be modified in-memory. The new method git_object_write() automatically writes back the in-memory changes of any object to the repository. So far it only supports git_commit objects.

Vicent Marti f49a2e49 2010-09-19T03:21:06 Give object structures more descriptive names The 'git_obj' structure is now called 'git_rawobj', since it represents a raw object read from the ODB. The 'git_repository_object' structure is now called 'git_object', since it's the base object class for all objects. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 46f8566a 2010-09-12T23:43:21 Add methods to access internal attributes in git_repo Added several methods to access: - The ODB behind a repo - The SHA1 id behind a generic repo object - The type of a generic repo object Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 370ce569 2010-08-14T20:35:10 Fix: do not export custom types in the extern API Some compilers give linking problems when exporting 'uint32_t' as a return type in the external API. Use generic types instead. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 9c9f4fc1 2010-08-12T23:40:54 Add support for manually freeing repo objects A new method 'git_repository_object_free' allows to manually force the freeing of a repository object, even though they are still automatically managed by the repository and don't need to be freed by the user. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 68535125 2010-07-09T20:19:56 Add support for git index files The new 'git_index' structure is an in-memory representation of a git index on disk; the 'git_index_entry' structures represent each one of the file entries on the index. The following calls for index instantiation have been added: git_index_alloc(): instantiate a new index structure git_index_free(): free an existing index git_index_clear(): clear all the entires in an existing file The following calls for index reading and writing have been added: git_index_read(): update the contents of the index structure from its file on disk. Internally implemented through: git_index__parse() Index files are stored on disk in network byte order; all integer fields inside them are properly converted to the machine's byte order when loading them in memory. The parsing engine also distinguishes between normal index entries and extended entries with 2 extra bytes of flags. The 'TREE' extension for index entries is also loaded into memory: Tree caches stored in Index files are loaded into the 'git_index_tree' structure pointed by the 'tree' pointer inside 'git_index'. 'index->tree' points to the root node of the tree cache; the full tree can be traversed through each of the node's 'tree->children'. Index files can be written back to disk through: git_index_write(): atomic writing of existing index objects backed by internal method git_index__write() The following calls for entry manipulation have been added: git_index_add(): insert an empty entry to the index git_index_find(): search an entry by its path name git_index__append(): appends a new index entry to the end of the list, resizing the entries array if required New index entries are always inserted at the end of the array; since the index entries must be sorted for it to be internally consistent, the index object is only sorted once, and if required, before accessing the whole entriea array (e.g. before writing to disk, before traversing, etc). git_index__remove_pos(): remove an index entry in a specific position git_index__sort(): sort the entries in the array by path name The entries array is sorted stably and in place using an insertion sort, which ought to be the most efficient approach since the entries array is always mostly-sorted.

Vicent Marti 003c2690 2010-08-12T18:45:31 Finish the tree object API The interface for loading and parsing tree objects from a repository has been completed with all the required accesor methods for attributes, support for manipulating individual tree entries and a new unit test t0901-readtree which tries to load and parse a tree object from a repository. Signed-off-by: Vicent Marti <tanoku@gmail.com>
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 f8758044 2010-08-07T01:02:20 Add loading and parsing of tag objects Tag objects are now properly loaded from the revision pool. New test t0801 checks for loading a parsing a series of tags, including the tag of a tag. 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 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.

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 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.

Shawn O. Pearce 5690f02e 2008-12-31T15:35:36 Rewrite git_foreach_dirent into gitfo_dirent Our fileops API is currently private. We aren't planning on supplying a cross-platform file API to applications that link to us. If we did, we'd probably whole-sale publish fileops, not just the dirent code. By moving it to be private we can also change the call signature to permit the buffer to be passed down through the call chain. This is very helpful when we are doing a recursive scan as we can reuse just one buffer in all stack frames, reducing the impact the recursion has on the stack frames in the data cache.

Shawn O. Pearce d44cfd46 2008-12-31T13:16:31 Cleanup our header inclusion order to ensure pthread.h is early If we are using threads we need to make sure pthread.h comes in before just about anything else.

Shawn O. Pearce 7dd8a9f7 2008-12-30T23:26:38 Set GIT_EOSERR when the OS errno should be consulted This error code indicates the OS error code has a better value describing the last error, as it is likely a network or local file IO problem identified by a C library function call. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
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. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce a1d34bc0 2008-12-30T21:49:38 Support building on Mac OS X by using pthread_getspecific for TLS The Mach-O format does not permit gcc to implement the __thread TLS specification, so we must instead emulate it using a single int cell allocated from memory and stored inside of the thread specific data associated with the current pthread. What makes this tricky is git_errno must be a valid lvalue, so we really need to return a pointer to the caller and deference it as part of the git_errno macro. The GCC-specific __attribute__((constructor)) extension is used to ensure the pthread_key_t is allocated before any Git functions are executed in the library, as this is necessary to access our thread specific storage.

Andreas Ericsson ec250c6e 2008-11-23T22:37:55 Remove config.h and make fileops an internal API Since it doesn't make sense to make the disk access stuff portable *AND* public (that's a job for each application imo), we can take a shortcut and just support unixy stuff for now and get away with coding most of it as macros. Since we go with an internal API for starters and only provide higher-level API's to the libgit users, we'll be ok with this approach.

Andreas Ericsson 4f0adcd0 2008-11-18T21:28:55 Get rid of GIT__PRIVATE macro Using it in the first place means something's wrong.

Andreas Ericsson 36f0f61f 2008-11-18T19:06:25 Add compiler/platform agnostic thread-local storage It doesn't cover all cases, but we can work on those as we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++, Sun Studio C/C++ and Borland C++ Builder are the supported compilers (although we boldly assume that they all are of a recent enough version to support thread-local storage). This is intended to be used in upcoming patches that implement graceful (but TLS-dependant) error-handling in the library. As an added bonus, we also bring the online_cpus() function from git.git to detect the number of usable cpu's. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.

Andreas Ericsson d4043ee9 2008-11-18T01:18:52 Move public headers to src/git It's arguably smoother to keep them close to the source, as that's where one's working when modifying them. More importantly, though, is the ability to use private headers in the src/ dir that simply include "git/$samename.h" to get to the public API at the same time.
