From 8e7fd3e06f300bd76b659db1164da1ee12f16870 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Timo=20Ter=C3=A4s?= Date: Tue, 12 Dec 2017 15:14:25 +0200 Subject: [PATCH] solver: fix potential install_if processing failure, fixes #8237 In discovery phase, there was logic to not process packages multiple times. However, that logic failed to account the package's depth and install_if state for the name being processed. This caused install_if processing failure in certain topologies of the dependency graph. Adds also a test case that should catch this issue reliably. --- src/solver.c | 95 +++++++++++++++++++++++++++------------------------- test/installif1.repo | 20 +++++++++++ test/installif5.test | 8 +++++ 3 files changed, 77 insertions(+), 46 deletions(-) create mode 100644 test/installif5.test diff --git a/src/solver.c b/src/solver.c index 5698215..851e77e 100644 --- a/src/solver.c +++ b/src/solver.c @@ -184,55 +184,57 @@ static void discover_name(struct apk_solver_state *ss, struct apk_name *name) name->ss.no_iif = 1;
