From 7f72b471bbfd449f4261d12cc7b062f6e7034283 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 19 May 2015 17:40:50 +0200 Subject: [PATCH] core: reinstate propagation of stop/restart jobs via RequsiteOf dependencies This reverts the primary effect of be7d9ff730cb88d7c6a869dd5c47754c78ceaef2. After all Requisite= should be close to Requires=, without the one exception that it doesn't pull in dependencies on start. However, reverse deps on stop/restart should be treated the same way as for Restart=, and this is already documented in the man page, hence stick to it. http://lists.freedesktop.org/archives/systemd-devel/2015-May/032049.html (cherry picked from commit ce74e76920dca603a12ef4bf605567965e9e7e45) [msekleta: we didn't backport be7d9ff730cb88d7c6a869dd5c47754c78ceaef2 and hence we don't have UNIT_REQUISITE_OF. Note that this patch was backported because it makes backports of followup patches easier] Related: #1436021 --- src/core/transaction.c | 41 +++++++++++++---------------------------- 1 file changed, 13 insertions(+), 28 deletions(-) diff --git a/src/core/transaction.c b/src/core/transaction.c index 57e9cb3f8..428b7671b 100644 --- a/src/core/transaction.c +++ b/src/core/transaction.c @@ -1008,40 +1008,25 @@ int transaction_add_job_and_dependencies( } if (type == JOB_STOP || type == JOB_RESTART) { + static const UnitDependency propagate_deps[] = { + UNIT_REQUIRED_BY, + UNIT_BOUND_BY, + UNIT_CONSISTS_OF, + }; - SET_FOREACH(dep, ret->unit->dependencies[UNIT_REQUIRED_BY], i) { - r = transaction_add_job_and_dependencies(tr, type, dep, ret, true, override, false, false, ignore_order, e); - if (r < 0) { - if (r != -EBADR) - goto fail; - - if (e) - sd_bus_error_free(e); - } - } - - SET_FOREACH(dep, ret->unit->dependencies[UNIT_BOUND_BY], i) { - r = transaction_add_job_and_dependencies(tr, type, dep, ret, true, override, false, false, ignore_order, e); - if (r < 0) { - if (r != -EBADR) - goto fail; + unsigned j; - if (e) - sd_bus_error_free(e); - } - } + for (j = 0; j < ELEMENTSOF(propagate_deps); j++) + SET_FOREACH(dep, ret->unit->dependencies[propagate_deps[j]], i) { - SET_FOREACH(dep, ret->unit->dependencies[UNIT_CONSISTS_OF], i) { - r = transaction_add_job_and_dependencies(tr, type, dep, ret, true, override, false, false, ignore_order, e); - if (r < 0) { - if (r != -EBADR) - goto fail; + r = transaction_add_job_and_dependencies(tr, type, dep, ret, true, override, false, false, ignore_order, e); + if (r < 0) { + if (r != -EBADR) + goto fail; - if (e) sd_bus_error_free(e); + } } - } - } if (type == JOB_RELOAD) {
