dulwich.bitmap.PackBitmap

class documentation

class PackBitmap:

A pack bitmap index.

Bitmaps store reachability information for commits in a packfile, allowing fast object enumeration without graph traversal.

Method	`__init__`	Initialize a pack bitmap.
Method	`get_bitmap`	Get the bitmap for a commit.
Method	`has_commit`	Check if a commit has a bitmap.
Method	`iter_commits`	Iterate over all commits with bitmaps.

Instance Variable	`entries_list`	Undocumented
Instance Variable	`flags`	Undocumented
Instance Variable	`lookup_table`	Undocumented

def __init__(self, version: int = BITMAP_VERSION, flags: int = BITMAP_OPT_FULL_DAG): ¶

Initialize a pack bitmap.

def get_bitmap(self, commit_sha: bytes) -> EWAHBitmap | None: ¶

Get the bitmap for a commit.

Parameters
commit_sha:`bytes`	SHA-1 of the commit

Returns
`EWAHBitmap \| None`	EWAH bitmap or None if not found

def has_commit(self, commit_sha: bytes) -> bool: ¶

Check if a commit has a bitmap.

Parameters
commit_sha:`bytes`	SHA-1 of the commit

Returns
`bool`	True if bitmap exists for this commit

def iter_commits(self) -> Iterator[bytes]: ¶

Iterate over all commits with bitmaps.

Returns
`Iterator[bytes]`	Iterator of commit SHAs
