b.generate_ids : module documentation

Part of bzrlib

Common code for generating file or revision ids.
Function gen_file_id Return new file id for the basename 'name'.
Function gen_root_id Return a new tree-root file id.
Function gen_revision_id Return new revision-id.
Function _next_id_suffix Create a new file id suffix that is reasonably unique.
def _next_id_suffix():
Create a new file id suffix that is reasonably unique.

On the first call we combine the current time with 64 bits of randomness to give a highly probably globally unique number. Then each call in the same process adds 1 to a serial number we append to that unique value.

def gen_file_id(name):
Return new file id for the basename 'name'.

The uniqueness is supplied from _next_id_suffix.

def gen_root_id():
Return a new tree-root file id.
def gen_revision_id(username, timestamp=None):
Return new revision-id.
ParametersusernameThe username of the committer, in the format returned by config.username(). This is typically a real name, followed by an email address. If found, we will use just the email address portion. Otherwise we flatten the real name, and use that.
ReturnsA new revision id.
