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. Zawinski, 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. � N�urlparse� urlunparse�urljoin� urldefrag�urlsplit� urlunsplit� urlencode�parse_qs� parse_qsl�quote� quote_plus�quote_from_bytes�unquote� unquote_plus�unquote_to_bytes� DefragResult� ParseResult� SplitResult�DefragResultBytes�ParseResultBytes�SplitResultBytes� Zftp�httpZgopherZnntpZimapZwais�fileZhttpsZshttpZmmsZprosperoZrtspZrtspuZsftpZsvnzsvn+sshZwsZwssZtelnetZsnewsZrsyncZnfsZgitzgit+sshZhdlZsipZsipsZtelZmailtoZnewszAabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+-.z! � � � � c C s t j� tj� dS )z,Clear the parse cache and the quoters cache.N)� _parse_cache�clear� _safe_quoters� r! r! �$/usr/lib64/python3.6/urllib/parse.py� clear_cache` s r# �ascii�strictc C s | S )Nr! )�objr! r! r" �_noopo s r' c C s | j ||�S )N)�encode)r& �encoding�errorsr! r! r" �_encode_resultr s r+ c s t � �fdd�| D ��S )Nc 3 s" | ]}|r|j � ��nd V qdS )r N)�decode)�.0�x)r) r* r! r" � <genexpr>x s z _decode_args.<locals>.<genexpr>)�tuple)�argsr) r* r! )r) r* r" � _decode_argsv s r2 c G sZ t | d t�}x.| dd � D ] }|r t |t�|kr td��q W |rL| tf S t| �tf S )Nr � z$Cannot mix str and non-str arguments)� isinstance�str� TypeErrorr' r2 r+ )r1 Z str_input�argr! r! r" � _coerce_argsz s r8 c @ s e Zd ZdZf Zddd�ZdS )�_ResultMixinStrz>Standard approach to encoding parsed results from str to bytesr$ r% c s | j � �fdd�| D �� S )Nc 3 s | ]}|j � ��V qd S )N)r( )r- r. )r) r* r! r" r/ � s z)_ResultMixinStr.encode.<locals>.<genexpr>)�_encoded_counterpart)�selfr) r* r! )r) r* r" r( � s z_ResultMixinStr.encodeN)r$ r% )�__name__� __module__� __qualname__�__doc__� __slots__r( r! r! r! r" r9 � s r9 c @ s e Zd ZdZf Zddd�ZdS )�_ResultMixinBytesz>Standard approach to decoding parsed results from bytes to strr$ r% c s | j � �fdd�| D �� S )Nc 3 s | ]}|j � ��V qd S )N)r, )r- r. )r) r* r! r" r/ � s z+_ResultMixinBytes.decode.<locals>.<genexpr>)�_decoded_counterpart)r; r) r* r! )r) r* r" r, � s z_ResultMixinBytes.decodeN)r$ r% )r< r= r> r? r@ r, r! r! r! r" rA � s rA c @ sD e Zd ZdZf Zedd� �Zedd� �Zedd� �Zedd � �Z d S ) �_NetlocResultMixinBasezHShared methods for the parsed result objects containing a netloc elementc C s | j d S )Nr )� _userinfo)r; r! r! r" �username� s z _NetlocResultMixinBase.usernamec C s | j d S )Nr3 )rD )r; r! r! r" �password� s z _NetlocResultMixinBase.passwordc C sD | j d }|sd S t|t�r dnd}|j|�\}}}|j� | | S )Nr �%� %)� _hostinfor4 r5 � partition�lower)r; �hostname� separatorZpercentZzoner! r! r" rL � s z _NetlocResultMixinBase.hostnamec C s@ | j d }|d k r<t|d�}d| ko.dkn s<td��|S )Nr3 � r i�� zPort out of range 0-65535)rI �int� ValueError)r; �portr! r! r" rQ � s z_NetlocResultMixinBase.portN) r< r= r> r? r@ �propertyrE rF rL rQ r! r! r! r" rC � s rC c @ s( e Zd Zf Zedd� �Zedd� �ZdS )�_NetlocResultMixinStrc C sD | j }|jd�\}}}|r4|jd�\}}}|s<d }nd }}||fS )N�@�:)�netloc� rpartitionrJ )r; rV �userinfo� have_info�hostinforE � have_passwordrF r! r! r" rD � s z _NetlocResultMixinStr._userinfoc C sl | j }|jd�\}}}|jd�\}}}|rL|jd�\}}}|jd�\}}}n|jd�\}}}|sdd }||fS )NrT �[�]rU )rV rW rJ )r; rV �_rZ � have_open_br� bracketedrL rQ r! r! r" rI � s z _NetlocResultMixinStr._hostinfoN)r< r= r> r@ rR rD rI r! r! r! r" rS � s rS c @ s( e Zd Zf Zedd� �Zedd� �ZdS )�_NetlocResultMixinBytesc C sD | j }|jd�\}}}|r4|jd�\}}}|s<d }nd }}||fS )N� @� :)rV rW rJ )r; rV rX rY rZ rE r[ rF r! r! r" rD � s z!_NetlocResultMixinBytes._userinfoc C sl | j }|jd�\}}}|jd�\}}}|rL|jd�\}}}|jd�\}}}n|jd�\}}}|sdd }||fS )Nrb � [� ]rc )rV rW rJ )r; rV r^ rZ r_ r` rL rQ r! r! r" rI � s z!_NetlocResultMixinBytes._hostinfoN)r< r= r> r@ rR rD rI r! r! r! r" ra � s ra )� namedtuplez url fragmentz!scheme netloc path query fragmentz(scheme netloc path params query fragmentz� DefragResult(url, fragment) A 2-tuple that contains the url without fragment identifier and the fragment identifier as a separate argument. z$The URL with no fragment identifier.z� Fragment identifier separated from URL, that allows indirect identification of a secondary resource by reference to a primary resource and additional identifying information. z� SplitResult(scheme, netloc, path, query, fragment) A 5-tuple that contains the different components of a URL.

RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists the following reserved characters. reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | "," Each of these characters is reserved in some component of a URL, but not necessarily in all of them. By default, the quote function is intended for quoting the path section of a URL. Thus, it will not encode '/'. This character is reserved, but in typical usage the quote function is being called on a path where the existing slash characters are used as reserved characters. string and safe may be either str or bytes objects. encoding and errors must not be specified if string is a bytes object. The optional encoding and errors parameters specify how to deal with non-ASCII characters, as accepted by the str.encode method. By default, encoding='utf-8' (characters are encoded with UTF-8), and errors='strict' (unsupported characters raise a UnicodeEncodeError).

If any values in the query arg are sequences and doseq is true, each sequence element is converted to a separate parameter. If the query arg is a sequence of two-element tuples, the order of the parameters in the output will match the order of parameters in the input. The components of a query arg may each be either a string or a bytes type. The safe, encoding, and errors parameters are passed down to the function specified by quote_via (encoding and errors only if a component is a str). �itemsr z1not a valid non-string sequence or mapping objectr� r� ) �hasattrr� rz r4 r0 r6 �sys�exc_info�with_tracebackr� r5 r� r� )rs Zdoseqr� r) r* Z quote_viaZtyZva�tb�l�kr� r.
