This holds three attributes: * `information` is a collection of `RequirementInformation` pairs. Each pair is a requirement contributing to this criterion, and the candidate that provides the requirement. * `incompatibilities` is a collection of all known not-to-work candidates to exclude from consideration. * `candidates` is a collection containing all possible candidates deducted from the union of contributing requirements and known incompatibilities. It should never be empty, except when the criterion is an attribute of a raised `RequirementsConflicted` (in which case it is always empty). .. note:: This class is intended to be externally immutable. **Do not** mutate any of its attribute containers. c(XlX lX0lgr candidates informationincompatibilities)rrFrGrHs rrCriterion.__init__As$&!2rchSRSUR55nSRU5$)Nr#c3F# UHupSRX5v M g7f)z({!r}, via={!r})N)r.)r(reqr s rr*%Criterion.__repr__..Gs'! /   % %c 2 2/s!z Criterion({}))r/rGr.)r requirementss r__repr__Criterion.__repr__Fs6yy! #//!  %%l33rc(SUR5$)Nc36# UHoRv M g7frr r(is rr*-Criterion.iter_requirement..Ns8'7!

When we enter here, the stack is like this:: [ state Z ] [ state Y ] [ state X ] .... earlier states are irrelevant. 1. No pins worked for Z, so it does not have a pin. 2. We want to reset state Y to unpinned, and pin another candidate. 3. State X holds what state Y was before the pin, but does not have the incompatibility information gathered in state Y. Each iteration of the loop will: 1. Identify Z. The incompatibility is not always caused by the latest state. For example, given three requirements A, B and C, with dependencies A1, B1 and C1, where A1 and B1 are incompatible: the last state might be related to C, so we want to discard the previous state. 2. Discard Z. 3. Discard Y but remember its incompatibility information gathered previously, and the failure we're dealing with right now. 4. Push a new state Y' based on X, and apply the incompatibility information from Y to Y'. 5a. If this causes Y' to conflict, we need to backtrack again. Make Y' the new Z and go back to step 2. 5b. If the incompatibilities apply cleanly, end backtracking. c3T# UHoRcMURv M! g7frr[r(cs rr*'Resolution._backjump...s >v!XQXXvs((c36# UHoRv M g7frrSrs rr*r/s +Fq]]Fr-r}Fc T>TGHupU(dMTRRUnTRR U[ TRR[ R"S55[ TRR[ R"S5X05S9n[U5nU(d gURUR5 [U[UR5US9TRRU'GM g![a GM"f=f)Nr0rHrFrET)r~rrrvrrrrrrextendrHrBrrG)krHrrrFincompatibilities_from_brokenrs r_patch_criteria-Resolution._backjump.._patch_criteriaQs ,I(A, !$(JJ$7$7$: #gg22#$%4 JJ//$112DE&+: JJ//$//0CD2+ 3 G"1!9J%$%,,Y-H-HI-6#-$()>)>$?*;.DJJ''*/-J8/$! !sD D'&D'T) itertoolschainrvrlenrxrrpopitemrrrcr isdisjointrrrrHrr)rrfincompatible_reqsr)incompatible_depsincompatible_state broken_staterr;dcurrent_dependenciesrvrsuccessrs` @r _backjumpResolution._backjumps>&OO >v > +F + ;LL:KQTWW--a0:KL$,,1$ R "' (7#'<<#3#3#5L&2&:&:&B&B&DOD "WW55i@(@GG$$Q'@%(*>)H)H%*&")(")11779-9DAD,,-.9- ) * 0 0$ 1D E >  "%'GG$,,1$RUM#H-7.v667(-s$F56F:$G8"G:Gc xUR(a [S5eURR5 [ [ R "50/S9/UlUH)nURURRUSS9 M+ UR5 [U5GHDnURR!US9 URRR#5VVs/sHupgUR%Xg5(aMUPM! nnnU(d1URR'URS9 URs $[)URRR+55[)U5- n [-XR.S9n UR1U 5n U (aU V V s/sHoRHoPM M nn n URR3US9 UR5U5nXRR6SS&U(d[URR65eOURRR#5VVs1sH&upgXi;dM UR%Xg5(aM$UiM( nnnUR9URRU5 UR5 URR;XPRS9 GMG [=U5e![a$n[URR5eSnAff=fs snnfs sn n fs snnf) Nzalready resolvedrr[)index)r~)rrh)rr~)rx RuntimeErrorrwstartingrp collections OrderedDictrr~rrrcrrGrrangestarting_roundrrendingsetkeysminrrresolving_conflictsrrr ending_roundrk)rrN max_roundsr)r round_indexrrunsatisfied_namessatisfied_namesrfailure_causesrrUrfrnewly_unsatisfied_namess rresolveResolution.resolve}s <<12 2  #//1!#   A D%%djj&9&91T%J  ,K GG " " " 5'+jj&9&9&?&?&A!&ANC66sF&A !%TZZ0zz!"$**"5"5":":"<=!AO (.B.BCD!;;DAN%3K^]]!]!^K++6+:..017 ++A..tzz/J/JKK+/***=*=*C*C*E+*E-!;;CK*E(+ 66JJ'')@$$& GG {** Ec-f ++w* D*1;;+B+BCC D!*L+s<!%K9)L*L*2L0!

The return value is a representation to the final resolution result. It is a tuple subclass with three public members: * `mapping`: A dict of resolved candidates. Each key is an identifier of a requirement (as returned by the provider's `identify` method), and the value is the resolved candidate. * `graph`: A `DirectedGraph` instance representing the dependency tree. The vertices are keys of `mapping`, and each edge represents *why* a particular package is included. A special vertex `None` is included to represent parents of user-supplied requirements. * `criteria`: A dict of "criteria" that hold detailed information on how edges in the graph are derived. Each key is an identifier of a requirement, and the value is a `Criterion` instance. The following exceptions may be raised if a resolution cannot be found: * `ResolutionImpossible`: A resolution cannot be found for the given combination of requirements. The `causes` attribute of the exception is a list of (requirement, parent), giving the requirements that could not be satisfied. * `ResolutionTooDeep`: The dependency tree is too deeply nested and the resolver gave up. This is usually caused by a circular dependency, but you can try to resolve this by increasing the `max_rounds` argument. )r)rrryrzrr)rrNr resolutionr~s rrResolver.resolves68  t}}= ""<"GU##rrN)d) rrrrrr base_exceptionrrrrrrrs=&N$rr)rrr providersrstructsrrr namedtupler Exceptionr rr8objectrBr`rcrkrprrrrrrrrrrs'DD$//}h7   .   -  $4$4N ' ?'' w(KL`,`,F &   *B C<#$#$r
