RFC 3986 (STD66): "Uniform Resource Identifiers" by T. Berners-Lee, R. Fielding and L. Masinter, January 2005. RFC 2732 : "Format for Literal IPv6 Addresses in URL's by R.Hinden, B.Carpenter and L.Masinter, December 1999. RFC 2396: "Uniform Resource Identifiers (URI)": Generic Syntax by T. Berners-Lee, R. Fielding, and L. Masinter, August 1998. RFC 2368: "The mailto URL scheme", by P.Hoffman , L Masinter, J. Zwinski, July 1998. RFC 1808: "Relative Uniform Resource Locators", by R. Fielding, UC Irvine, June 1995. RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M. McCahill, December 1994 RFC 3986 is considered the current standard and any future changes to urlparse module should conform with it. The urlparse module is currently not entirely compliant with this RFC due to defacto scenarios for parsing, and for backward compatibility purposes, some parsing quirks from older RFCs are retained. The testcases in test_urlparse.py provides a good indicator of parsing behavior. The WHATWG URL Parser spec should also be considered. We are not compliant with it either due to existing user code API behavior expectations (Hyrum's Law). It serves as a useful guide when making changes. i˙˙˙˙Nt urlparset urlunparset urljoint urldefragt urlsplitt urlunsplitt parse_qst parse_qslt ftpt httpt gophert nntpt imapt waist filet httpst shttpt mmst prosperot rtspt rtsput t sftpt svns svn+ssht telnett snewst rsynct nfst gits git+ssht hdlt sipt sipst telt mailtot newssA abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+-.t! s s s i c C s t j d S( s Clear the parse cache.N( t _parse_cachet clear( ( ( s /usr/lib64/python2.7/urlparse.pyt clear_cacheO s t ResultMixinc B sJ e Z d Z e d Z e d Z e d Z e d Z RS( s- Shared methods for the parsed result objects.c C sX | j } d | k rT | j d d d } d | k rP | j d d d } n | Sd S( Nt @i i t :( t netloct rsplitt splitt None( t selfR* t userinfo( ( s /usr/lib64/python2.7/urlparse.pyt usernameW s c C sR | j } d | k rN | j d d d } d | k rN | j d d d Sn d S( NR( i i R) ( R* R+ R, R- ( R.
