GenerateDiff()

def upload.MercurialVCS.GenerateDiff	(		self,
			args
	)

Return the current diff as a string.

Args:
  args: Extra arguments to pass to the diff command.

Reimplemented from upload.VersionControlSystem.

Definition at line 1079 of file upload.py.

GetBaseFile()

def upload.MercurialVCS.GetBaseFile	(		self,
			filename
	)

Get the content of the upstream version of a file.

Returns:
  A tuple (base_content, new_content, is_binary, status)
    base_content: The contents of the base file.
    new_content: For text files, this is empty.  For binary files, this is
      the contents of the new file, since the diff output won't contain
      information to reconstruct the current file.
    is_binary: True iff the file is binary.
    status: The status of the file.

Reimplemented from upload.VersionControlSystem.

Definition at line 1117 of file upload.py.

GetUnknownFiles()
