dulwich.pack.DeltaChainIterator(object) class documentation

Part of dulwich.pack (View In Hierarchy)

Known subclasses: dulwich.pack.PackIndexer, dulwich.pack.PackInflater, dulwich.tests.test_pack.TestPackIterator

Abstract iterator over pack data based on delta chains.

Each object in the pack is guaranteed to be inflated exactly once, regardless of how many objects reference it as a delta base. As a result, memory usage is proportional to the length of the longest delta chain.

Subclasses can override _result to define the result type of the iterator. By default, results are UnpackedObjects with the following members set:

  • offset
  • obj_type_num
  • obj_chunks
  • pack_type_num
  • delta_base (for delta types)
  • comp_chunks (if _include_comp is True)
  • decomp_chunks
  • decomp_len
  • crc32 (if _compute_crc32 is True)
