Message

Andrey Shinkevich July 30, 2020, 2:15 p.m. UTC

Add dirty bitmap information to QCOW2 metadata dump in the qcow2_format.py.

v10:
  01: New. The test case #303 added to visualize the QCOW2 metadata dumping.
      Suggested by Eric. The patch "Fix capitalization of header extension
      constant" has been pulled separately.
  07: The class Qcow2BitmapTableEntry is now derived from the Qcow2Struct
      one. The constructors and methods of Qcow2BitmapTable and of
      Qcow2BitmapTableEntry were modified.
  09: The python dict.update method was replaced with assignment operator.
      The interleaving dict 'entries' was removed from bitmap table dump.
  10: The class Qcow2HeaderExtensionsDoc was removed.
  11: New. The #303 was extended by dumping QCOW2 metadata in JSON format.
