class URI(object):
|

"""
|
|
A class representing a generic URI, with methods for
|
|
accessing the URI components, and stringifies to the
|
|
URI.
|
|
|
|
It is constructed by calling it with a URI, or setting
|
|
the attributes manually:
|
|
|
|
uri = URI("http://example.com/")
|
|
|
|
uri = URI()
|
|
uri.scheme = 'http'
|
|
uri.hostname = 'example.com'
|
|
uri.path = '/'
|
|
|
|
It has the following attributes:
|
|
|
|
* scheme (read/write)
|
|
* userinfo (authentication information) (read/write)
|
|
* username (read/write)
|
|
* password (read/write)
|
|
|
|
Note, password is deprecated as of RFC 3986.
|
|
|
|
* hostname (read/write)
|
|
* port (read/write)
|
|
* hostport (read only)
|
|
"hostname:port", if both are set, otherwise just "hostname"
|
|
* path (read/write)
|
|
* path_quoted (read/write)
|
|
A URI quoted version of path
|
|
* params (dict) (read/write)
|
|
* relative (bool) (read only)
|
|
True if this is a "relative URI", (e.g. file:foo.diff)
|
|
|
|
It stringifies to the URI itself.
|
|
|
|
Some notes about relative URIs: while it's specified that
|
|
a URI beginning with <scheme>:// should either be directly
|
|
followed by a hostname or a /, the old URI handling of the
|
|
fetch2 library did not comform to this. Therefore, this URI
|
|
class has some kludges to make sure that URIs are parsed in
|
|
a way comforming to bitbake's current usage. This URI class
|
|
supports the following:
|
|
|
|
file:relative/path.diff (IETF compliant)
|
|
git:relative/path.git (IETF compliant)
|
|
git:///absolute/path.git (IETF compliant)
|
|
file:///absolute/path.diff (IETF compliant)
|
|
|
|
file://relative/path.diff (not IETF compliant)
|
|
|
|
But it does not support the following:
|
|
|
|
file://hostname/absolute/path.diff (would be IETF compliant)
|
|
|
|
Note that the last case only applies to a list of
|
|
"whitelisted" schemes (currently only file://), that requires
|
|
its URIs to not have a network location.
