"""
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.
