Constructor & Destructor Documentation

__init__()

def upload.GitVCS.__init__	(		self,
			options

Member Function Documentation

GenerateDiff()

def upload.GitVCS.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 1008 of file upload.py.

  def GenerateDiff(self, extra_args):
    # This is more complicated than svn's GenerateDiff because we must convert
    # the diff output to include an svn-style "Index:" line as well as record
    # the hashes of the base files, so we can upload them along with our diff.
    if self.options.revision:
      extra_args = [self.options.revision] + extra_args
    gitdiff = RunShell(["git", "diff", "--full-index"] + extra_args)

        #   index 82c0d44..b2cee3f 100755
        # We want to save the left hash, as that identifies the base file.

    return "".join(svndiff)
 

GetBaseFile()

def upload.GitVCS.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 1041 of file upload.py.

  def GetBaseFile(self, filename):
    hash = self.base_hashes[filename]
    base_content = None
    new_content = None
    is_binary = False
    if hash == "0" * 40:  # All-zero hash indicates no base file.
      status = "A"
      base_content = ""
    else:
      status = "M"
      base_content, returncode = RunShellWithReturnCode(["git", "show", hash])
      if returncode:
        ErrorExit("Got error status from 'git show %s'" % hash)
    return (base_content, new_content, is_binary, status)
 
 

GetUnknownFiles()

def upload.GitVCS.GetUnknownFiles

(

self

)

Return a list of files unknown to the VCS.

Reimplemented from upload.VersionControlSystem.

Definition at line 1036 of file upload.py.

  def GetUnknownFiles(self):
    status = RunShell(["git", "ls-files", "--exclude-standard", "--others"],
                      silent_ok=True)
    return status.splitlines()
