Vicent Marti e035685f 2010-12-23T00:44:41 Revert "Properly export all external symbols in Win32" It is not a good idea to export these internal symbols now that they are not required to run the unit tests. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 9f54fe48 2010-12-23T00:15:09 Remove git_errno It was not being used by any methods (only by malloc and calloc), and since it needs to be TLS, it cannot be exported on DLLs on Windows. Burn it with fire. The API always returns error codes! Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 11f6646f 2010-12-22T22:51:24 Export TLS symbols properly in Win32 There was no export definition for GIT_EXTERN_TLS() under MSVC. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 2a18a792 2010-12-22T22:43:39 Properly export all external symbols in Win32 Some external functions were not being exported because they were using the 'extern' keyword instead of the generic GIT_EXTERN() macro. Signed-off-by: Vicent Marti <tanoku@gmail.com>
nulltoken 2c08c3f0 2010-12-21T06:52:07 Made is_windows_rooted_path() able to cope with awkward but valid relative paths such as "C:..\File.txt". Path "C:..\File.txt" refers to a file called File.txt located in the parent directory of the current directory on drive C:.

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 d80e9d55 2010-10-31T06:01:46 Fix in-memory commit getters trying to parse Issue 9 on the tracker. The commit object getters for in-memory objects were trying to parse an inexistant on-disk object when one of the commit attributes which were still not set was queried. We now return a NULL value when this happens. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 57450775 2010-10-29T02:44:32 Do a full parse on commits before modifying them Before changing the attributes of a commit, make sure that the internal status is consistent with the one in the repository. 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.

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>
Ramsay Jones e3005627 2010-10-12T19:11:51 bswap.h: Add ntohs() and htons() functions Since commit 70aab459, the msvc and MinGW builds have relied on the built-in implementation of ntohl() and htonl(), rather than linking the wsock32 library. The new index manipulation code now calls ntohs()/htons() in addition to ntohl()/htonl(), so we need to provide a built-in implementation of the 16-bit functions.

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.

Vicent Marti e802d8cc 2010-09-19T03:53:57 Implement internal methods to write on sources The new 'git__source_printf' does an overflow-safe printf on a source bfufer. The new 'git__source_write' does an overflow-safe byte write on a source buffer. Signed-off-by: Vicent Marti <tanoku@gmail.com>
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 a7a7ddbe 2010-09-18T19:16:04 Add generic methods for object writeback git_repository_object has now several internal methods to write back the object information in the repository. - git_repository__dbo_prepare_write() Prepares the DBO object to be modified - git_repository__dbo_write() Writes new bytes to the DBO object - git_repository__dbo_writeback() Writes back the changes to the repository Signed-off-by: Vicent Marti <tanoku@gmail.com>

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. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti bd0a51c0 2010-07-09T20:17:00 Add support for atomic file locking The struct 'git_filelock' represents an atomically-locked file, git-style. Locked files can be modified atomically through the new file lock interface: int git_filelock_init(git_filelock *lock, const char *path); int git_filelock_lock(git_filelock *lock, int append); void git_filelock_unlock(git_filelock *lock); int git_filelock_commit(git_filelock *lock); int git_filelock_write(git_filelock *lock, const char *buffer, size_t length); 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>

The 'git_commit_person' struct has been changed to a generic 'git_person'. Signed-off-by: Vicent Marti <tanoku@gmail.com>
