From 4e1b93d8e18f451f76fd6f8c966c0fbeb3b8c56b Mon Sep 17 00:00:00 2001 From: Christophe Fergeau Date: Tue, 28 Jul 2009 13:15:32 +0000 Subject: unselect current package if an avoided package is already selected Patch by Anssi Hannula, fixes bug #52145 If package 'a' Conflicts on 'b', and user (or a dependency chain) tries to install both at the same time, perl-URPM will only detect the conflict if package 'a' gets selected first (this depends on hdlist order), as _set_rejected_from is only called in one direction from _handle_conflicts and it does not detect that a package it is about to reject_from is already selected. This bug currently causes a failure in urpmi handle-conflict-deps2 testcase. This commit checks if avoided package is already selected, and unselects current package in such a case --- URPM/Resolve.pm | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) (limited to 'URPM/Resolve.pm') diff --git a/URPM/Resolve.pm b/URPM/Resolve.pm index 5c51206..279e58c 100644 --- a/URPM/Resolve.pm +++ b/URPM/Resolve.pm @@ -984,7 +984,7 @@ sub resolve_requested__no_suggests_ { _unselect_package_deprecated_by($urpm, $db, $state, \%diff_provides_h, $pkg); } - _handle_conflicts_with_selected($urpm, $state, $pkg); + _handle_conflicts_with_selected($urpm, $db, $state, $pkg, $dep, \@properties) or next; #- all requires should be satisfied according to selected package, or installed packages. if (my @l = unsatisfied_requires($urpm, $db, $state, $pkg)) { @@ -1035,20 +1035,31 @@ sub resolve_requested__no_suggests_ { grep { exists $state->{selected}{$_->id} } @selected; } -#- pre-disables packages that $pkg has conflict entries for +#- pre-disables packages that $pkg has conflict entries for, and +#- unselects $pkg if such a package is already selected #- side-effects: #- + those of _set_rejected_from ($state->{rejected}) +#- + those of disable_selected (flag_requested, flag_required, $state->{selected}, $state->{rejected}, $state->{whatrequires}) +#- + those of backtrack_selected ($state->{backtrack}, $state->{rejected}, $state->{selected}, $state->{whatrequires}, flag_requested, flag_required) sub _handle_conflicts_with_selected { - my ($urpm, $state, $pkg) = @_; + my ($urpm, $db, $state, $pkg, $dep, $properties) = @_; foreach ($pkg->conflicts) { if (my ($n, $o, $v) = property2name_op_version($_)) { foreach my $p ($urpm->packages_providing($n)) { $pkg == $p and next; $p->provides_overlap($_) or next; + if (exists $state->{selected}{$p->id}) { + $urpm->{debug_URPM}($pkg->fullname .
