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.

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. c C s | | _ | | _ d S( N( t baset extras( RJ R� R� ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRO � s c C s( d j d | j j d | j d | j � S( Ns. {class_name}(base={base!r}, extras={extras!r})RP R� R� ( R: RQ RR R� R� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRS � s c C s t | j | j f � S( N( RT R� R� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRU � s c C s8 t | | j � r4 | j | j k o3 | j | j k St S( N( RV RQ R� R� RH ( RJ RW ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRX � s "c C s | j | � S( N( RX ( RJ RW ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRY � s c C s t | j j | j � S( s: The normalised name of the project the candidate refers to( R R� RM R� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRM � s c C s | j j S( N( R� RN ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRN � s c C s+ d j | j j � d j t | j � � � S( Ns {} [{}]s , ( R: R� R\ t joint sortedR� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyR\ � s c C s | j j S( N( R� R� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyR� � s c C s | j j S( N( R� R� ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyR� � s c C s | j j S( N( R� RK ( RJ ( ( s� /builddir/build/BUILDROOT/alt-python27-pip-20.2.4-5.el8.x86_64/opt/alt/python27/lib/python2.7/site-packages/pip/_internal/resolution/resolvelib/candidates.pyRK s c c s� | j j } | j | j � V| s' d S| j j | j j j � } | j j | j j j � } x3 t | � D]% } t j d | j j | j | � qj WxL | j j j | � D]5 } | j t | � | j j | � } | r� | Vq� q� Wd S( Ns% %s %s does not provide the extra '%s'( R� RB t make_requirement_from_candidateR� t intersectionR= t differenceR� Rj Rr RM RN Rx Ry R.
