dulwich.archive module

Generates tarballs for Git trees.

class dulwich.archive.ChunkedBytesIO(contents)

Bases: object

Turn a list of bytestrings into a file-like object.

This is similar to creating a BytesIO from a concatenation of the bytestring list, but saves memory by NOT creating one giant bytestring first:

BytesIO(b''.join(list_of_bytestrings)) =~= ChunkedBytesIO(
    list_of_bytestrings)

read(maxbytes=None)

dulwich.archive.tar_stream(store, tree, mtime, prefix='', format='')

Generate a tar stream for the contents of a Git tree.

Returns a generator that lazily assembles a .tar.gz archive, yielding it in pieces (bytestrings). To obtain the complete .tar.gz binary file, simply concatenate these chunks.

Parameters:

• store – Object store to retrieve objects from
• tree – Tree object for the tree root
• mtime – UNIX timestamp that is assigned as the modification time for all files, and the gzip header modification time if format=’gz’
• format – Optional compression format for tarball

Returns:

Bytestrings
