Vicent Marti d0323a5f 2011-06-01T21:25:56 short-oid: Cleanup
Marc Pegon 6c8ca697 2011-05-29T17:57:25 Fixed some error messages related to searching objects from a short oid. Fixed forgot to check that prefix length is greater than minimum prefix length in read_unique_short_oid method from pack backend.
Marc Pegon dd453c4d 2011-05-27T22:46:41 Added git.git sha1 lookup method to replace simple binary search in pack backend. Implemented find_unique_short_oid for pack backend, based on git sha1 lookup method; finding an object given its full oid is just a particular case of searching the unique object matching an oid prefix (short oid). Added git_odb_read_unique_short_oid, which iterates over all the backends to find and read the unique object matching the given oid prefix. Added a git_object_lookup_short_oid method to find the unique object in the repository matching a given oid prefix : it generalizes git_object_lookup which now does nothing but calls git_object_lookup_short_oid.

Sergey Nikishin 411823a3 2011-04-24T16:02:57 Fix whole buffer writing in fake wstream
Vicent Marti d69d0185 2011-04-04T13:05:20 Add a fake wstream to the ODB Streaming writes will no longer fail when writing to a backend that doesn't support streaming writes but supports direct ones. Now we create a fake stream on memory and then write it as a single block using the backend `write` callback.
Vicent Marti f6f72d7e 2011-03-23T18:44:53 Improve the ODB writing backend Temporary files when doing streaming writes are now stored inside the Objects folder, to prevent issues when moving files between disks/partitions. Add support for block writes to the ODB again (for those backends that cannot implement streaming).
Vicent Marti 1881f078 2011-03-21T20:28:02 Add getters for `git_odb_object`
Vicent Marti 72a3fe42 2011-03-18T19:38:49 I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now *mandatory*. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid *id, const void *data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)` - Change `git_odb_read_header`: New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype) int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 86d7e1ca 2011-02-28T12:46:13 Fix searching in git_vector We now store only one sorting callback that does entry comparison. This is used when sorting the entries using a quicksort, and when looking for a specific entry with the new search methods. The following search methods now exist: git_vector_search(vector, entry) git_vector_search2(vector, custom_search_callback, key) git_vector_bsearch(vector, entry) git_vector_bsearch2(vector, custom_search_callback, key) The sorting state of the vector is now stored internally.

Vicent Marti d4b5a4e2 2011-02-09T19:49:02 Internal changes on the backend system The priority value for different backends has been removed from the public `git_odb_backend` struct. We handle that internally. The priority value is specified on the `git_odb_add_alternate`. This is convenient because it allows us to poll a backend twice with different priorities without having to instantiate it twice. We also differentiate between main backends and alternates; alternates have lower priority and cannot be written to. These changes come with some unit tests to make sure that the backend sorting is consistent. The libgit2 version has been bumped to 0.4.0. This commit changes the external API: CHANGED: struct git_odb_backend No longer has a `priority` attribute; priority for the backend in managed internally by the library. git_odb_add_backend(git_odb *odb, git_odb_backend *backend, int priority) Now takes an additional priority parameter, the priority that will be given to the backend. ADDED: git_odb_add_alternate(git_odb *odb, git_odb_backend *backend, int priority) Add a backend as an alternate. Alternate backends have always lower priority than main backends, and writing is disabled on them. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Vicent Marti <tanoku@gmail.com>

Ramsay Jones 2cdc4544 2010-02-26T22:53:10 Add a pack index 'virtual function' to fetch an index entry Given an index entry number, the idx_get() function returns an (version agnostic) index_entry structure containing all of the information required to unpack the corresponding object from the '.pack' file. Since the v1 and v2 file formats differ in the layout of the object records, we provide two implementations of the get function and initialise the function pointer appropriately.

Ramsay Jones 608d33fa 2010-02-26T19:59:06 Add a pack index 'virtual function' to search by file offset In addition to searching the index by oid, we need to search by '.pack' file offset, particularly when processing OBJ_OFS_DELTA objects. Since the v1 and v2 file formats differ in the layout of the object records, we provide two implementations of the search function and initialise the (virtual) function pointer appropriately. Note that, as part of the creation of the 'offset index', we also add a check that the offset data in the index is within the bounds of the '.pack' file. Having sorted the file offsets, while creating the index, we only need to check the smallest and largest values. The offset index consists of the im_off_idx array, which contains the index entry numbers sorted into file offset order, and the im_off_next mapping array. The im_off_next array maps an index entry number to the 'next' index entry in file offset order. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Ramsay Jones ac04bdf6 2009-06-04T16:44:54 Fix a usage error in a call to the object_file_name() function In 82324ac, the new static function exists_loose() called object_file_name() and, in order to detect an error return, tested for a negative value. This usage is incorrect, as the error return is indicated by a positive return value. (A successful call is indicated by a zero return value) The only error return from object_file_name() relates to insufficient buffer space and the return value gives the required minimum buffer size (which will always be >0). If the caller requires a dynamically allocated buffer, this allows something like the following call sequence: size_t len = object_file_name(NULL, 0, db->object_dir, id); char *buf = git__malloc(len); if (!buf) error(...); object_file_name(buf, len, db->object_dir,id); ... No current callers take advantage of this capability. Fix up the call site and change the return type of the function, from int to size_t, which more accurately reflects the implementation.

Shawn O. Pearce bed3229b 2009-01-03T03:34:09 Precompute the fanout decoding and the oid offset in a pack-*.idx The fanout table is fairly commonly accessed, we need to read it twice for each object we lookup in any given pack file. Most of the processors running Git are running in little-endian mode, as they are variants of the x86 platform, so reading the fanout is a costly operation as we need to convert from network byte order to local byte order. By decoding the fanout table into a malloc obtained buffer we can save these 2 decode operations per lookup and make search go more quickly. This also cleans up the initialization of the search functions by cutting out a few instructions, saving a small amount of time. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce a7c60cfc 2009-01-03T02:41:26 Add basic support to read pack-*.idx v1 and v2 files The index data is mapped into memory and then scanned using a binary search algorithm to locate the matching entry for the supplied git_oid. The standard fanout hash trick is applied to reduce the search space by 8 iterations. Since the v1 and v2 file formats differ in their search function, due to the different layouts used for the object records, we use two different search implementations and a virtual function pointer to jump to the correct version of code for the current pack index. The single function jump per-pack should be faster then computing a branch point inside the inner loop of a common binary search. To improve concurrency during read operations the pack lock is only held while verifying the index is actually open, or while opening the index for the first time. This permits multiple concurrent readers to scan through the same index. If an invalid index file is opened we close it and mark the git_pack's invalid bit to true. The git_pack structure is kept around in its parent git_packlist, but the invalid bit will cause all future readers to skip over the pack entirely. Pruning the invalid entries is relatively unimportant because they shouldn't be very common, a $GIT_DIRECTORY/objects/pack directory tends to only have valid pack files. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 098ac57a 2009-01-03T00:02:25 Refactor pack memory management and locking to be safer Using an atomic reference counter is difficult to make cross-platform, as the reference count implementations are generally processor specific. Its also hard to do a proper multi-read/single-write implementation. We now use a simple mutex around the reference count for the list of packs. Readers grab the mutex and either build the list, or increment the existing one's reference count. When the reader is done with the list, the reference count is decremented. In this way parallel readers are able to operate on the list without worrying about it being deallocated out from under them. Individual pack structures are held by reference counts, but we only care about the list the pack structure is held in. There is no need to increment/decrement the pack reference counts as we scan through them during a read operation, the caller holds the git_packlist and that is sufficient to hold the packs it references.

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.

Pearce ffb55c53 2008-12-30T22:29:04 Rename the path of the objects directory to be more specific We're likely to add additional path data, like the path of the refs or the path to the config file into the git_odb structure, as it may grow into the repository wrapper. Changing the name of the objects directory reference makes it more clear should we later add something else. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 4c67e2e9 2008-12-30T22:25:30 Change git_odb__read_packed to return ENOTFOUND until implemented We didn't search for the object, so we cannot possibly promise it to the caller of git_odb_read(). Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 064301cc 2008-12-30T22:07:56 Fix size_t snprintf warning by using PRIuPTR format macro This is the correct C99 format code for the size_t type when passed as an argument to the *printf family. If the platform doesn't define it, we assume %lu and just cross our fingers that its the proper setting for a size_t on this system. On most sane platforms, "unsigned long" is the underlying type of "size_t". Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Andreas Ericsson dff79e27 2008-11-18T00:59:36 Rename "git_sobj" "git_obj" The 's' never really made sense, since it's not a "small" object at all, but rather a plain object. As such, it should have a "plain" object name. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce 1699efc4 2008-11-03T18:39:37 Implement some of the basic git_odb open and close API Far from being complete, but its a good start. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
