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 �� t�� dS )z,Clear the parse cache and the quoters cache.N)� _parse_cache�clear� _safe_quoters� r! r! �1/opt/alt/python38/lib64/python3.8/urllib/parse.py� clear_cache_ s r# �ascii�strictc C s | S �Nr! )�objr! r! r" �_noopn s r( c C s | � ||�S r& ��encode)r' �encoding�errorsr! r! r" �_encode_resultq s r- c s t � �fdd�| D ��S )Nc 3 s" | ]}|r|� � ��nd V qdS )r N��decode��.0�x�r+ r, r! r" � <genexpr>w s z _decode_args.<locals>.<genexpr>)�tuple)�argsr+ r, r! r3 r" � _decode_argsu s r7 c G sV t | d t�}| dd � D ] }|rt |t�|krtd��q|rH| tf S t| �tf S )Nr � z$Cannot mix str and non-str arguments)� isinstance�str� TypeErrorr( r7 r- )r6 Z str_input�argr! r! r" � _coerce_argsy s r= c @ s e Zd ZdZdZddd�ZdS ) �_ResultMixinStrz>Standard approach to encoding parsed results from str to bytesr! r$ r% c s | j � �fdd�| D �� S )Nc 3 s | ]}|� � ��V qd S r& r) r0 r3 r! r" r4 � s z)_ResultMixinStr.encode.<locals>.<genexpr>)�_encoded_counterpart��selfr+ r, r! r3 r" r* � s z_ResultMixinStr.encodeN)r$ r% )�__name__� __module__� __qualname__�__doc__� __slots__r* r! r! r! r" r> � s r> c @ s e Zd ZdZdZddd�ZdS ) �_ResultMixinBytesz>Standard approach to decoding parsed results from bytes to strr! r$ r% c s | j � �fdd�| D �� S )Nc 3 s | ]}|� � ��V qd S r& r. r0 r3 r! r" r4 � s z+_ResultMixinBytes.decode.<locals>.<genexpr>)�_decoded_counterpartr@ r! r3 r" r/ � s z_ResultMixinBytes.decodeN)r$ r% )rB rC rD rE rF r/ r! r! r! r" rG � s rG c @ sD e Zd ZdZdZedd� �Zedd� �Zedd� �Zed d � �Z d S ) �_NetlocResultMixinBasezHShared methods for the parsed result objects containing a netloc elementr! c C s | j d S )Nr �� _userinfo�rA r! r! r" �username� s z _NetlocResultMixinBase.usernamec C s | j d S )Nr8 rJ rL r! r! r" �password� s z _NetlocResultMixinBase.passwordc C sD | j d }|sd S t|t�r dnd}|�|�\}}}|�� | | S )Nr �%� %)� _hostinfor9 r: � partition�lower)rA �hostname� separatorZpercentZzoner! r! r" rT � s z _NetlocResultMixinBase.hostnamec C sl | j d }|d k rhzt|d�}W n( tk rH d|��}t|�d �Y nX d| kr^dkshn td��|S )Nr8 � z+Port could not be cast to integer value as r i�� zPort out of range 0-65535)rQ �int� ValueError)rA �port�messager! r! r" rY � s z_NetlocResultMixinBase.portN) rB rC rD rE rF �propertyrM rN rT rY r! r! r! r" rI � s rI c @ s( e Zd ZdZedd� �Zedd� �ZdS )�_NetlocResultMixinStrr! c C sD | j }|�d�\}}}|r4|�d�\}}}|s<d }nd }}||fS )N�@�:��netloc� rpartitionrR �rA r` ZuserinfoZ have_info�hostinforM Z have_passwordrN r! r! r" rK � s z _NetlocResultMixinStr._userinfoc C sl | j }|�d�\}}}|�d�\}}}|rL|�d�\}}}|�d�\}}}n|�d�\}}}|sdd }||fS )Nr] �[�]r^ r_ �rA r` �_rc Z have_open_brZ bracketedrT rY r! r! r" rQ � s z _NetlocResultMixinStr._hostinfoN�rB rC rD rF r[ rK rQ r! r! r! r" r\ � s r\ c @ s( e Zd ZdZedd� �Zedd� �ZdS )�_NetlocResultMixinBytesr! c C sD | j }|�d�\}}}|r4|�d�\}}}|s<d }nd }}||fS )N� @� :r_ rb r! r! r" rK � s z!_NetlocResultMixinBytes._userinfoc C sl | j }|�d�\}}}|�d�\}}}|rL|�d�\}}}|�d�\}}}n|�d�\}}}|sdd }||fS )Nrj � [� ]rk r_ rf r! r! r" rQ � s z!_NetlocResultMixinBytes._hostinfoNrh r! r! r! r" ri � s ri )� 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.

The quote function offers a cautious (not minimal) way to quote a string for most of these parts. RFC 3986 Uniform Resource Identifier (URI): Generic Syntax lists the following (un)reserved characters. unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~" reserved = gen-delims / sub-delims gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@" sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "=" Each of the reserved characters is reserved in some component of a URL, but not necessarily in all of them. The quote function %-escapes all characters that are neither in the unreserved chars ("always safe") nor the additional chars set via the safe arg. The default for the safe arg is '/'. The character is reserved, but in typical usage the quote function is being called on a path where the existing slash characters are to be preserved. Python 3.7 updates from using RFC 2396 to RFC 3986 to quote URL strings. Now, "~" is included in the set of unreserved 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).

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� r� r9 r5 r; �sys�exc_info�with_tracebackr� r: r� r� )r Zdoseqr� r+ r, Z quote_viaZtyZva�tb�l�kr� r2 Zeltr! r! r" r � sR � c C s t jdtdd� t| �S )Nz/urllib.parse.to_bytes() is deprecated as of 3.8r� �� stacklevel)�warnings�warn�DeprecationWarning� _to_bytes�rr r! r! r" �to_bytes� s �r� c C sJ t | t�rFz| �d��� } W n( tk rD tdt| � d ��Y nX | S )zto_bytes(u"URL") --> 'URL'.�ASCIIzURL z contains non-ASCII characters)r9 r: r* r/ � UnicodeError�reprr� r! r! r" r� � s � r� c C s` t | ��� } | dd� dkr<| dd� dkr<| dd� �� } | dd� dkr\| dd� �� } | S )z�Transform a string like '<URL:scheme://host/path>' into 'scheme://host/path'.
