Recent attempt to add a lot of meson options to specify different runtime paths motivated me enough to cleanup this from meson. Changes in v3: - some patches were already pushed - removed patch that moved virFindFileInPath from testutilsqemu.c Changes in v2: - split and rework patch 16/17 to address review comments - added a new patch to cleanup libvirt.spec.in file Pavel Hrdina (8): virfile: introduce virFindFileInPathFull() qemu_conf: use virFindFileInPathFull for runtime binaries meson: drop check for runtime binary dependencies meson: move iscsiadm check into storage_iscsi condition meson: stop setting runtime binaries defines during compilation meson: use runtime binaries to only resolve features with "auto" value meson: optional_programs should be used only for building libvirt libvirt.spec: drop no longer required build dependencies libvirt.spec.in | 31 ---- meson.build | 214 +++++++++---------------- src/bhyve/bhyve_command.c | 4 + src/libvirt_private.syms | 2 +- src/locking/lock_driver_lockd.c | 12 +- src/network/bridge_driver.c | 2 + src/node_device/node_device_driver.c | 2 + src/qemu/qemu_conf.c | 23 ++- src/storage/storage_backend_logical.c | 13 ++ src/storage/storage_backend_sheepdog.c | 2 + src/storage/storage_backend_zfs.c | 3 + src/storage/storage_util.c | 2 + src/storage/storage_util.h | 6 + src/util/virdnsmasq.c | 1 + src/util/virfile.c | 16 +- src/util/virfile.h | 5 +- src/util/virfirewall.h | 4 + src/util/viriscsi.h | 2 + src/util/virkmod.h | 3 + src/util/virnetdevbandwidth.h | 2 + src/util/virnetdevip.c | 2 + src/util/virnetdevmidonet.c | 2 + src/util/virnetdevopenvswitch.c | 2 + src/util/virnuma.c | 1 + src/util/virsysinfo.c | 1 + src/util/virutil.c | 2 + tests/testutilsqemu.c | 3 +- tests/virfirewallmock.c | 3 +- 28 files changed, 173 insertions(+), 192 deletions(-) -- 2.31.1

New subject: [PATCH RESEND v3 3/8] meson: drop check for runtime binary dependencies

These binaries are used only during runtime so technically there is no need to check for them while compiling libvirt. Usually the location is the same while compiling and running but it may not be true. In addition they are not strictly required to compile the code so this way developers don't have to install it or create fake binaries in order to compile the code.

New subject: [PATCH RESEND v3 5/8] meson: stop setting runtime binaries defines during compilation

Technically the location of these binaries may be different when compiling libvirt or running it. This will allow users to change $PATH to use different binaries as well.

This way meson will try to do the right thing by default but we will allow users to change this behavior by using -Dname=enabled. This comes with two benefits compared to the previous behavior: - no need to install the binaries if developers would like to check that the code compiles correctly - package maintainers can drop some build dependencies Signed-off-by: Pavel Hrdina <phrdina(a)redhat.com> --- meson.build | 102 ++++++++++++++++++++++++++++++++-------------------- 1 file changed, 63 insertions(+), 39 deletions(-) diff --git a/meson.build b/meson.build index 2900b6e1a8..8e8d31953d 100644 --- a/meson.build +++ b/meson.build @@ -977,12 +977,6 @@ endif libparted_version = '1.8.0' libparted_dep = dependency('libparted', version: '>=' + libparted_version, required: false) -if libparted_dep.found() -

Are we? scrub is needed if and only if you want to pass a special algorithm to virStorageVolWipePattern(). Does that justify a runtime dependency? We fail gracefully if scrub isn't installed. We aren't even requiring qemu binary for daemon-driver-qemu package. Wasn't the whole idea to drop dependencies? Michal

The point was to drop **build** dependencies, specifically problematic ones such as ZFS. When it comes to runtime dependencies, our RPMs generally try to be as featureful as possible, so adding a dependency on scrub is the right thing to do IMO. -- Andrea Bolognani / Red Hat / Virtualization

Why is ZFS problematic? The zfs-fuse package is totally fine for us to depend on... -- 真実はいつも一つ！/ Always, there's only one truth!

I'm not too familiar with the ZFS situation in Fedora / RHEL, but at least in Debian we're patching meson.build specifically to enable ZFS support without needing a ZFS implementation available at build time. In general, using the build time availability of programs to guess whether features should be enabled is a good, user-friendly behavior, but we shouldn't second-guess the information provided by the user: if they passed -Dstorage_zfs=enabled to Meson, then we should enable ZFS support whether or not ZFS happens to be currently installed. -- Andrea Bolognani / Red Hat / Virtualization
