In 'make syntax-check', we have a rule that prevents layering violations between the various files in src. However, we forgot to treat conf/ and the more recently-added access/ as lower-level directories, and were not detecting cases where they might have used a driver file. Also, it's not nice that qemu can use storage/ but none of the other drivers could do so. * cfg.mk (sc_prohibit_cross_inclusion): Tighten rules for conf/ and access/, let all other drivers use storage/. Signed-off-by: Eric Blake <eblake(a)redhat.com&gt; --- I noticed this because of my work on domain_conf.h: I want to share a struct between util/virstoragefile and conf/domain_conf, and ran into a syntax check when I tried to make util/ depend on conf/. I fixed things to obey layering with conf/ depending on util/, but in the process noticed that some layering violations went undetected. cfg.mk | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/cfg.mk b/cfg.mk index a4ae978..19537cf 100644 --- a/cfg.mk +++ b/cfg.mk @@ -760,17 +760,17 @@ sc_prohibit_gettext_markup: # lower-level code must not include higher-level headers. cross_dirs=$(patsubst $(srcdir)/src/%.,%,$(wildcard $(srcdir)/src/*/.)) cross_dirs_re=($(subst / ,/|,$(cross_dirs))) +mid_dirs=access|conf|cpu|locking|network|node_device|rpc|security|storage sc_prohibit_cross_inclusion: @for dir in $(cross_dirs); do \ case $$dir in \ util/) safe="util";; \ - locking/) \ - safe="($$dir|util|conf|rpc)";; \ - cpu/ | locking/ | network/ | rpc/ | security/) \ + access/ | conf/) safe="($$dir|conf|util)";; \ + locking/) safe="($$dir|util|conf|rpc)";; \ + cpu/| network/| node_device/| rpc/| security/| storage/) \ safe="($$dir|util|conf)";; \ xenapi/ | xenxs/ ) safe="($$dir|util|conf|xen)";; \ - qemu/ ) safe="($$dir|util|conf|cpu|network|locking|rpc|security|storage)";; \ - *) safe="($$dir|util|conf|cpu|network|locking|rpc|security)";; \ + *) safe="($$dir|$(mid_dirs)|util)";; \ esac; \ in_vc_files="^src/$$dir" \ prohibit='^# *include .$(cross_dirs_re)' \ -- 1.8.5.3
