This represents a package request with the target not being already in the environment, and needs to be fetched and installed. The backing ``InstallRequirement`` is responsible for most of the leg work; this class exposes appropriate information to the resolver. :param link: The link passed to the ``InstallRequirement``. The backing ``InstallRequirement`` will use this link to fetch the distribution. :param source_link: The link this candidate "originates" from. This is different from ``link`` when the link is found in the wheel cache. ``link`` would point to the wheel cache, while this points to the found remote link (e.g. from pypi.org). rA FNr )r+ � source_linkr= �factory�namerC r% c C s8 || _ || _|| _|| _|| _|| _| �� | _d | _d S �N) �_link� _source_link�_factory�_ireq�_name�_version�_preparerA �_hash)�selfr+ rG r= rH rI rC r( r( r) �__init__� s z+_InstallRequirementBackedCandidate.__init__�r% c C s | j � d| j� �S )N� �rI rC �rS r( r( r) �__str__� s z*_InstallRequirementBackedCandidate.__str__c C s | j j� dt| j��d�S �N�(�))� __class__�__name__r8 rK rX r( r( r) �__repr__� s z+_InstallRequirementBackedCandidate.__repr__c C s( | j d ur| j S t| j| jf�| _ | j S rJ )rR �hashr] rK rX r( r( r) �__hash__� s z+_InstallRequirementBackedCandidate.__hash__��otherr% c C s t || j�rt| j|j�S dS �NF)r& r] r rK �rS rc r( r( r) �__eq__� s z)_InstallRequirementBackedCandidate.__eq__c C s | j S rJ )rL rX r( r( r) rG � s z._InstallRequirementBackedCandidate.source_linkc C s | j du r| jj| _ | j S )�:The normalised name of the project the candidate refers toN)rO rA rB rX r( r( r) � project_name� s z/_InstallRequirementBackedCandidate.project_namec C s | j S rJ �rh rX r( r( r) rI � s z'_InstallRequirementBackedCandidate.namec C s | j d u r| jj| _ | j S rJ �rP rA rC rX r( r( r) rC � s z*_InstallRequirementBackedCandidate.versionc C s, | j � d| j� d| jjr | jjn| j� d�S )NrV z (from r\ )rI rC rK �is_file� file_pathrX r( r( r) �format_for_error� s ��z3_InstallRequirementBackedCandidate.format_for_errorc C s t d��d S )NzOverride in subclass)�NotImplementedErrorrX r( r( r) �_prepare_distribution� s z8_InstallRequirementBackedCandidate._prepare_distribution)rA r% c C s� | j dur*| j |jkr*t| jd| j |j��| jdur\| j|jkr\t| jdt| j�t|j���zt|�t|� � ��� W n4 t y� } z t | jt|���W Y d}~n d}~0 0 dS )z:Check for consistency of project name and version of dist.NrI rC ) rO rB r rN rP rC r8 �list�iter_dependencies�iter_provided_extrasr r )rS rA �er( r( r) �_check_metadata_consistency� s$ �� z>_InstallRequirementBackedCandidate._check_metadata_consistencyc C st z | � � }W nX ty: } z| j|_� W Y d }~n4d }~0 tyd } zd|_� W Y d }~n d }~0 0 | �|� |S )NzSee above for output.)ro r rN r7 r �contextrt )rS rA rs �excr( r( r) rQ � s z+_InstallRequirementBackedCandidate._prepare�� with_requiresr% c c sL | j �| jj�V |r | j�� nd}|D ] }| j �t|�| j�E d H q(d S �Nr( )rM � make_requires_python_requirementrA �requires_pythonrq �make_requirements_from_specr8 rN )rS rx �requires�rr( r( r) rq � s z4_InstallRequirementBackedCandidate.iter_dependenciesc C s | j S rJ )rN rX r( r( r) �get_install_requirement s z:_InstallRequirementBackedCandidate.get_install_requirement)NN)"r^ � __module__� __qualname__�__doc__r �__annotations__� is_installedr r r r r rT r8 rY r_ �intra r �boolrf �propertyrG rh rI rC rm ro rt rQ r r rq r r( r( r( r) rF } s@ �� rF c sH e Zd ZdZd eedee ee dd�� fdd� Z e d�dd �Z � Z S ) r# FNr �r+ r, rH rI rC r% c s4 |}|� ||�}|d ur,t�d|j� |j}t||�}|j|ksDJ �|jjr�|jjs�t|jj�} t | j �} || ks�J |�d| �d���|d ur�t | j �} || ks�J |�d| �d|� ���|d u�r|jjs�J �|jjs�J �|j r�|j|ju r�||_|jd u�r|j|_nt||j d�|_t� j||||||d� d S )NzUsing cached wheel link: %sz != z for wheelz for wheel )�link_is_in_wheel_cache�r+ rG r= rH rI rC )�get_wheel_cache_entry�logger�debugr+ r> �is_wheelrk r �filenamer rI r rC � persistentr: �cached_wheel_source_link�origin� download_infor �superrT ) rS r+ r, rH rI rC rG � cache_entryr= �wheel� wheel_name� wheel_version�r] r( r) rT sF �� ��zLinkCandidate.__init__rU c C s | j j}|j| jdd�S )NT)�parallel_builds)rM �preparer�prepare_linked_requirementrN )rS r� r( r( r) ro ; s z#LinkCandidate._prepare_distribution)NN� r^ r� r� � is_editabler r r r r rT r ro � __classcell__r( r( r� r) r# s ��1r# c sH e Zd ZdZd eedee ee dd�� fdd� Z e d�dd �Z � Z S ) r" TNr r� c s" t � j||t||�|||d� d S )Nr� )r� rT r@ )rS r+ r, rH rI rC r� r( r) rT C s �zEditableCandidate.__init__rU c C s | j j�| j�S rJ )rM r� � prepare_editable_requirementrN rX r( r( r) ro T s z'EditableCandidate._prepare_distribution)NNr� r( r( r� r) r" @ s ��r" c @ s� e Zd ZdZdZeeddd�dd�Zed�dd �Z ed�d d �Z e e d �d d�Z ed�dd�Zeed�dd��Zeed�dd��Zeed�dd��Zee d�dd��Zed�dd�Ze eee d�d d �Zee d�d d �Z dS ) r!

Requirements can be for a project with dependencies, something like foo[extra]. The extras don't affect the project/version being installed directly, but indicate that we need additional dependencies. We model that by having an artificial ExtrasCandidate that wraps the "base" candidate. The ExtrasCandidate differs from the base in the following ways: 1. It has a unique name, of the form foo[extra]. This causes the resolver to treat it as a separate node in the dependency graph. 2. When we're getting the candidate's dependencies, a) We specify that we want the extra dependencies as well. b) We add a dependency on the base candidate. See below for why this is needed. 3. We return None for the underlying InstallRequirement, as the base candidate will provide it, and we don't want to end up with duplicates. The dependency on the base candidate is needed so that the resolver can't decide that it should recommend foo[extra1] version 1.0 and foo[extra2] version 2.0. Having those candidates depend on foo=1.0 and foo=2.0 respectively forces the resolver to recognise that this is a conflict. N)r/ )�baser; r/ r% c C s4 || _ tdd� |D ��| _|dur&|n| j j| _dS )a� :param comes_from: the InstallRequirement that led to this candidate if it differs from the base's InstallRequirement. This will often be the case in the sense that this candidate's requirement has the extras while the base's does not. Unlike the InstallRequirement backed candidates, this requirement is used solely for reporting purposes, it does not do any leg work. c s s | ]}t |�V qd S rJ )r )�.0rs r( r( r) � <genexpr>� � z+ExtrasCandidate.__init__.<locals>.<genexpr>N)r� � frozensetr; rN � _comes_from)rS r� r; r/ r( r( r) rT � s zExtrasCandidate.__init__rU c C s, t | j��dd�\}}d�|d�| j�|�S )NrV r z {}[{}] {}�,)r8 r� �split�format�joinr; )rS rI �restr( r( r) rY � s zExtrasCandidate.__str__c C s | j j� d| j�d| j�d�S )Nz(base=z , extras=r\ )r] r^ r� r; rX r( r( r) r_ � s zExtrasCandidate.__repr__c C s t | j| jf�S rJ )r` r� r; rX r( r( r) ra � s zExtrasCandidate.__hash__rb c C s( t || j�r$| j|jko"| j|jkS dS rd )r& r] r� r; re r( r( r) rf � s zExtrasCandidate.__eq__c C s | j jS rJ )r� rh rX r( r( r) rh � s z ExtrasCandidate.project_namec C s t | jj| j�S )rg )r r� rh r; rX r( r( r) rI � s zExtrasCandidate.namec C s | j jS rJ )r� rC rX r( r( r) rC � s zExtrasCandidate.versionc C s d� | j�� d�t| j���S )Nz{} [{}]z, )r� r� rm r� �sortedr; rX r( r( r) rm � s �z ExtrasCandidate.format_for_errorc C s | j jS rJ )r� r� rX r( r( r) r� � s z ExtrasCandidate.is_installedc C s | j jS rJ )r� r� rX r( r( r) r� � s zExtrasCandidate.is_editablec C s | j jS rJ )r� rG rX r( r( r) rG � s zExtrasCandidate.source_linkrw c c s� | j j}|�| j �V |s d S | j�| j j�� �}| j�| j j�� �}t|�D ]}t � d| j j | j |� qN| j j� |�D ] }|�t|�| j|�E d H qxd S )Nz%%s %s does not provide the extra '%s')r� rM � make_requirement_from_candidater; � intersectionrA rr � differencer� r� �warningrI rC rq r| r8 r� )rS rx rH � valid_extras�invalid_extras�extrar~ r( r( r) rq � s& ��z!ExtrasCandidate.iter_dependenciesc C s d S rJ r( rX r( r( r) r s z'ExtrasCandidate.get_install_requirement) r^ r� r� r� � BaseCandidater r8 r r rT rY r_ r� ra r r� rf r� r rh rI r rC rm r� r� r rG r r rq r r( r( r( r) r� � s6 �� r� c @ s� e Zd ZdZdZeeedf dd�dd�Ze d�dd �Z e d�d d �Z e e d�d d ��Ze e d�dd��Ze ed�dd��Ze d�dd�Zeeee d�dd�Zee d�dd�ZdS )�RequiresPythonCandidateFN.)�py_version_infor% c C s> |d urt |�}ntjd d� }td�dd� |D ���| _d S )N� �.c s s | ]}t |�V qd S rJ )r8 )r� �cr( r( r) r� $ r� z3RequiresPythonCandidate.__init__.<locals>.<genexpr>)r �sys� version_infor r� rP )rS r� r� r( r( r) rT s z RequiresPythonCandidate.__init__rU c C s d| j � �S �NzPython �rP rX r( r( r) rY * s z RequiresPythonCandidate.__str__c C s | j j� d| j�d�S rZ )r] r^ rP rX r( r( r) r_ - s z RequiresPythonCandidate.__repr__c C s t S rJ ��REQUIRES_PYTHON_IDENTIFIERrX r( r( r) rh 0 s z$RequiresPythonCandidate.project_namec C s t S rJ r� rX r( r( r) rI 4 s z RequiresPythonCandidate.namec C s | j S rJ r� rX r( r( r) rC 8 s z RequiresPythonCandidate.versionc C s d| j � �S r� )rC rX r( r( r) rm < s z(RequiresPythonCandidate.format_for_errorrw c C s dS ry r( )rS rx r( r( r) rq ? s z)RequiresPythonCandidate.iter_dependenciesc C s d S rJ r( rX r( r( r) r B s z/RequiresPythonCandidate.get_install_requirement)r^ r� r� r� rG r r r� rT r8 rY r_ r� r rh rI r rC rm r� r r rq r r r( r( r( r) r� s r� )=�loggingr� �typingr r r r r r r r �"pip._vendor.packaging.requirementsr Zpip._vendor.packaging.utilsr r � pip._vendor.packaging.versionr �pip._internal.exceptionsr r r r r �pip._internal.metadatar �pip._internal.models.linkr r �pip._internal.models.wheelr � pip._internal.req.constructorsr r � pip._internal.req.req_installr �&pip._internal.utils.direct_url_helpersr �pip._internal.utils.miscr r� r r r rH r � getLoggerr^ r� r� r� r* r> r@ rE rF r# r" r! r� r� r( r( r( r) �<module> sL ( � � � � 9G|
