This may be specified by a data-requires-python attribute in the HTML link tag, as described in PEP 503. :param yanked_reason: the reason the file has been yanked, if the file has been yanked, or None if the file hasn't been yanked. This is the value of the "data-yanked" attribute, if present, in a simple repository HTML link. If the file has been yanked but no reason was provided, this should be the empty string. See PEP 592 for more information and the specification. :param metadata_file_data: the metadata attached to the file, or None if no such metadata is provided. This argument, if not None, indicates that a separate metadata file exists, and also optionally supplies hashes for that file. :param cache_link_parsing: A flag that is used elsewhere to determine whether resources retrieved from this link should be cached. PyPI URLs should generally have this set to False, for example. :param hashes: A mapping of hash names to digests to allow us to determine the validity of a download. z\\N)r` r rX rY rv r� r� r[ rd r� r r7 r9 r� r� r� r� r� r� � _egg_fragmentr� ) r- r0 r� r� r� r� r� r> Z link_hashZhashes_from_linkr# r# r$ �__init__� s ( z Link.__init__zdict[str, Any]z Link | None)� file_data�page_urlr* c C s� |� d�}|du rdS tt||��}|� d�}|� d�}|� di �}|� d�}|du r`|� d�}t|t�rxtt|��} n|r�td�} nd} |r�t|t�s�d}n|s�d}| |||||| d �S ) zZ Convert an pypi json document from a simple repository page into a Link. r0 Nzrequires-pythonZyankedr> z core-metadatazdist-info-metadatarf )r� r� r� r> r� )�getr{ r~ � isinstance�dictrM rV r ) r5 r� r� �file_urlr0 � pyrequirer� r> � metadata_infor� r# r# r$ � from_json s6 �zLink.from_jsonzdict[str, str | None])�anchor_attribsr� r| r* c C s� |� d�}|sdS tt||��}|� d�}|� d�}|� d�}|du rP|� d�}|dkrbtd�} nL|du rpd} n>|�d�\} } } | dkr�tt| | i��} nt�d |� td�} | ||||| d �S ) z_ Convert an anchor element's attributes in a simple repository page to a Link. �hrefNzdata-requires-pythonz data-yankedzdata-core-metadatazdata-dist-info-metadata�true�=z8Index returned invalid data-dist-info-metadata value: %s)r� r� r� r� )r� r{ r~ rM � partitionrV �logger�debug) r5 r� r� r| r� r0 r� r� r� r� Zhashname�sepZhashvalr# r# r$ � from_elementJ s8 ��zLink.from_elementr) c C sB | j rd| j � d�}nd}| jr8| j� d| j� d|� �S | jS d S )Nz (requires-python:�)rf z (from )r� r� � redacted_url)r- �rpr# r# r$ �__str__~ s z Link.__str__c C s d| � d�S )Nz<Link �>r# r, r# r# r$ �__repr__� s z Link.__repr__�intc C s t | j�S r )�hashr0 r, r# r# r$ �__hash__� s z Link.__hash__r )�otherr* c C s t |t�stS | j|jkS r �r� r �NotImplementedr0 �r- r� r# r# r$ �__eq__� s z Link.__eq__c C s t |t�stS | j|jk S r r� r� r# r# r$ �__lt__� s z Link.__lt__c C s | j S r )r� r, r# r# r$ r0 � s zLink.urlc C s t | j�S r )r r0 r, r# r# r$ r� � s zLink.redacted_urlc C sR | j �d�}t�|�}|s,t| j�\}}|S tj�|�}|sNJ d| j �d���|S )N�/zURL z produced no filename) rd �rstrip� posixpath�basenamer rw rX rY r[ r� )r- rd r rw � user_passr# r# r$ �filename� s z Link.filenamec C s t | j�S r )r r0 r, r# r# r$ � file_path� s zLink.file_pathc C s | j jS r )r� rt r, r# r# r$ rt � s z Link.schemec C s | j jS )z4 This can contain auth information. )r� rw r, r# r# r$ rw � s z Link.netlocc C s | j S r )r� r, r# r# r$ rd � s z Link.pathztuple[str, str]c C s t t�| j�d���S )Nr� )r r� r� rd r� r, r# r# r$ r � s z Link.splitextc C s | � � d S �N� )r r, r# r# r$ �ext� s zLink.extc C s& | j \}}}}}tj�||||df�S )Nrf )r� rX rY rx )r- rt rw rd �query�fragmentr# r# r$ �url_without_fragment� s zLink.url_without_fragmentz[#&]egg=([^&]*)z)^([A-Z0-9]|[A-Z0-9][A-Z0-9._-]*[A-Z0-9])$c C sF | j �| j�}|sd S |�d�}| j�|�sBt| � d�dddd� |S )Nr� z2 contains an egg fragment with a non-PEP 508 name.z8to use the req @ url syntax, and remove the egg fragmentz25.3ie3 )�reason� replacement�gone_in�issue)�_egg_fragment_rer3 r� �group�_project_name_rer6 r )r- r6 � project_namer# r# r$ r� � s �zLink._egg_fragmentz[#&]subdirectory=([^&]*)c C s | j �| j�}|sd S |�d�S r� )�_subdirectory_fragment_rer3 r� r� )r- r6 r# r# r$ �subdirectory_fragment� s zLink.subdirectory_fragmentc C s> | j du rdS | j� d�}| j jdu r.t|�S t|| j jd�S )z<Return a link to the associated core metadata file (if any).Nz .metadatarU )r� r� r> r )r- Z metadata_urlr# r# r$ � metadata_link� s zLink.metadata_linkr c C s t dd� | j�� D ��S )Nc S s i | ]\}}||g�qS r# r# �r! �krR r# r# r$ rS � r& z"Link.as_hashes.<locals>.<dictcomp>)r r� rT r, r# r# r$ r: � s zLink.as_hashesc C s t t| j�� �d �S r )�next�iterr� �valuesr, r# r# r$ r� � s z Link.hashc C s t t| j�d �S r )r� r� r� r, r# r# r$ r" � s zLink.hash_namec C s$ t �| j�dd�d �dd�d �S )N�#r� r �?)r� r� r� rh r, r# r# r$ �show_url s z Link.show_urlc C s | j dkS )Nrs )rt r, r# r# r$ �is_file s z Link.is_filec C s | j otj�| j�S r )r� �osrd �isdirr� r, r# r# r$ �is_existing_dir s zLink.is_existing_dirc C s | j tkS r )r� r r, r# r# r$ �is_wheel s z Link.is_wheelc C s ddl m} | j|jv S )Nr )�vcs)�pip._internal.vcsr� rt � all_schemes)r- r� r# r# r$ �is_vcs s z Link.is_vcsc C s | j d uS r )r� r, r# r# r$ � is_yanked s zLink.is_yankedc C s t | j�S r )r< r� r, r# r# r$ �has_hash s z Link.has_hashr; r= c s( � du r dS t � fdd�| j�� D ��S )zS Return True if the link has a hash and it is allowed by `hashes`.

This is used in the resolver to check whether two URL-specified requirements likely point to the same distribution and can be considered equivalent. This equivalency logic avoids comparing URLs literally, which can be too strict (e.g. "a=1&b=2" vs "b=2&a=1") and produce conflicts unexpecting to users. Currently this does three things: 1. Drop the basic auth part. This is technically wrong since a server can serve different content based on auth, but if it does that, it is even impossible to guarantee two URLs without auth are equivalent, since the user can input different auth information when prompted. So the practical solution is to assume the auth doesn't affect the response. 2. Parse the query to avoid the ordering issue. Note that ordering under the same key in the query are NOT cleaned; i.e. "a=1&a=2" and "a=2&a=1" are still considered different. 3. Explicitly drop most of the fragment part, except ``subdirectory=`` and hash values, since it should have no impact the downloaded content. Note that this drops the "egg=" part historically used to denote the requested project (and extras), which is wrong in the strictest sense, but too many people are supplying it inconsistently to cause superfluous resolution conflicts, so we choose to also ignore them. zurllib.parse.SplitResult�parsedzdict[str, list[str]]r� r � subdirectoryr8 r> N)rB rC rD rE rF r# r# r# r$ r� ) s r� )�linkr* c s� | j }|j�dd�d }|jdkr*|s*d}tj�|j�� d� v rLt� d| � z� d d }W n t t fyv d }Y n0 � fd d �t D �}t |j|d d d �tj�|j�||d�S )N�@r� ���rs � localhost�eggz Ignoring egg= fragment in %sr� r rf c s" i | ]}|� v r|� | d �qS )r r# )r! r� �r� r# r$ rS Z r& z _clean_link.<locals>.<dictcomp>)rw r� r� )r� r� r� r> )r� rw �rsplitrt rX rY �parse_qsr� r� r� � IndexError�KeyErrorr+ r� ry r� )r� r� rw r� r> r# r� r$ � _clean_linkI s$ �r� )�link1�link2r* c C s t | �t |�kS r )r� )r� r� r# r# r$ �links_equivalentc s r� )7� __future__r rK ri �loggingr� r� r � urllib.parserX �collections.abcr Z dataclassesr �typingr r r � pip._internal.utils.deprecationr � pip._internal.utils.filetypesr �pip._internal.utils.hashesr �pip._internal.utils.miscr r r r �pip._internal.utils.urlsr r � pip._internal.index.collectorr � getLoggerrB r� r+ r rM rV r\ rc rG r� rg rr r{ r~ �total_orderingr r� r� rL r� r# r# r# r$ �<module> sL 5 e
