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`

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.

Git trees are now always lazily sorted
Removed `git_tree_add_entry_unsorted`. Now the `git_tree_add_entry`
method doesn't sort the entries array by default; entries are only
sorted lazily when required. This is done automatically by the library
(the `git_tree_sort_entries` call has been removed).
This should improve performance. No point on sorting entries all the time, anyway.

Keep the tree entries always internally sorted
Don't allow access to any tree entries whilst the entries array is
unsorted. We keep track on when the array is unsorted, and any methods
that access the array while it is unsorted now sort the array before
accessing it.

Use Git's own tree entry sorting algorithm
If plain strcmp is used, as this code did before, the final sorting may
end up different from what git-add would do (for example, 'boost'
appearing before 'boost-build.jam', because Git sorts as if it were
spelled 'boost/').
If the sorting is incorrect like this, Git 1.7.4 insists that unmodified
files have been modified. For example, my test repository has these
four entries:
drwxr-xr-x 199 johnw wheel 6766 Feb 2 17:21 boost
-rw-r--r-- 1 johnw wheel 849 Feb 2 17:22 boost-build.jam
-rw-r--r-- 1 johnw wheel 989 Feb 2 17:21 boost.css
-rw-r--r-- 1 johnw wheel 6308 Feb 2 17:21 boost.png
Here is the output from git-ls-tree for these files, in a commit tree
created using git-add and git-commit:
100644 blob 8b8775433aef73e9e12609610ae2e35cf1e7ec2c boost-build.jam
100644 blob 986c4050fa96d825a1311c8e871cdcc9a3e0d2c3 boost.css
100644 blob b4d51fcd5c9149fd77f5ca6ed2b6b1b70e8fe24f boost.png
040000 tree 46537eeaa4d577010f19b1c9e940cae9a670ff5c boost
Here is the output for the same commit produced using libgit2:
040000 tree c27c0fd1436f28a6ba99acd0a6c17d178ed58288 boost
100644 blob 8b8775433aef73e9e12609610ae2e35cf1e7ec2c boost-build.jam
100644 blob 986c4050fa96d825a1311c8e871cdcc9a3e0d2c3 boost.css
100644 blob b4d51fcd5c9149fd77f5ca6ed2b6b1b70e8fe24f boost.png
Due to this reordering, git-status claims the three blobs are always
modified, no matter what I do using git-read-tree or git-reset or
git-checkout to update the index.

- 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

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.
