Method	`add_object`	Add a single object to this object store.
Method	`add_pack`	Add a new pack to this object store.
Method	`add_thin_pack`	Read a thin pack
Method	`find_missing_objects`	Find the missing objects required for a set of revisions.
Method	`iter_shas`	An iterator over pack's ObjectStore.
Method	`pack_info_get`	Undocumented
Instance Variable	`pack_dir`	Undocumented
Instance Variable	`root`	Undocumented
Instance Variable	`scon`	Undocumented
Method	`_collect_ancestors`	Collect all ancestors of heads up to (excluding) those in common.
Method	`_complete_thin_pack`	Undocumented
Method	`_get_loose_object`	Undocumented
Method	`_iter_loose_objects`	Loose objects are not supported by this repository
Method	`_pack_cache_stale`	Undocumented
Method	`_update_pack_cache`	Undocumented
Instance Variable	`_alternates`	Undocumented

Inherited from PackBasedObjectStore:

Method	`__contains__`	Check if a particular object is present by SHA1.
Method	`__iter__`	Iterate over the SHAs that are present in this store.
Method	`add_objects`	Add a set of objects to this object store.
Method	`close`	Close any files opened by this object store.
Method	`contains_loose`	Check if a particular object is present by SHA1 and is loose.
Method	`contains_packed`	Check if a particular object is present by SHA1 and is packed.
Method	`get_raw`	Obtain the raw fulltext for an object.
Method	`pack_loose_objects`	Pack loose objects.
Method	`repack`	Repack the packs in this repository.
Instance Variable	`pack_compression_level`	Undocumented
Property	`alternates`	Undocumented
Property	`packs`	List with pack objects.
Method	`_add_cached_pack`	Add a newly appeared pack to the cache by path.
Method	`_clear_cached_packs`	Undocumented
Method	`_iter_alternate_objects`	Iterate over the SHAs of all the objects in alternate stores.
Method	`_iter_cached_packs`	Undocumented
Method	`_remove_loose_object`	Undocumented
Method	`_remove_pack`	Undocumented
Instance Variable	`_pack_cache`	Undocumented

Inherited from BaseObjectStore (via PackBasedObjectStore):

Method	`__getitem__`	Obtain an object by SHA1.
Method	`add_pack_data`	Add pack data to this object store.
Method	`determine_wants_all`	Undocumented
Method	`find_common_revisions`	Find which revisions this store has in common using graphwalker.
Method	`generate_pack_contents`	Iterate over the contents of a pack file.
Method	`generate_pack_data`	Generate pack data objects for a set of wants/haves.
Method	`iter_tree_contents`	Iterate the contents of a tree and all subtrees.
Method	`peel_sha`	Peel all tags from a SHA.
Method	`tree_changes`	Find the differences between the contents of two trees
Method	`_get_depth`	Return the current available depth for the given head. For commits with multiple parents, the largest possible depth will be returned.

def __init__(self, scon): ¶

overrides dulwich.object_store.PackBasedObjectStore.__init__

Open a Swift object store.

Parameters
scon	A `SwiftConnector` instance

def add_object(self, obj): ¶

overrides dulwich.object_store.BaseObjectStore.add_object

Add a single object to this object store.

def add_pack(self): ¶

overrides dulwich.object_store.BaseObjectStore.add_pack

Add a new pack to this object store.

Returns: Fileobject to write to and a commit function to: call when the pack is finished.

def add_thin_pack(self, read_all, read_some): ¶

Read a thin pack

Read it from a stream and complete it in a temporary file. Then the pack and the corresponding index file are uploaded to Swift.

def find_missing_objects(self, *args, **kwargs): ¶

overrides dulwich.object_store.BaseObjectStore.find_missing_objects

Find the missing objects required for a set of revisions.

Returns: Iterator over (sha, path) pairs.

Parameters
*args	Undocumented
**kwargs	Undocumented
haves	Iterable over SHAs already in common.
wants	Iterable over SHAs of objects to fetch.
shallow	Set of shallow commit SHA1s to skip
progress	Simple progress function that will be called with updated progress strings.
get_tagged	Function that returns a dict of pointed-to sha -> tag sha for including tags.
get_parents	Optional function for getting the parents of a commit.

def iter_shas(self, finder): ¶

overrides dulwich.object_store.BaseObjectStore.iter_shas

An iterator over pack's ObjectStore.

Returns: a ObjectStoreIterator or GreenThreadsObjectStoreIterator: instance if gevent is enabled

def _collect_ancestors(self, heads, common=set()): ¶

Returns: a tuple (A, B) where A - all commits reachable: from heads but not present in common, B - common (shared) elements that are directly reachable from heads

Parameters
heads	commits to start from
common	commits to end at, or empty set to walk repository completely
