We call systemd a "project", and "package" is something that distros build. Let's rename. PACKAGE_URL is renamed to PROJECT_URL for the same reasons and for consistency.

This change creates an overhead for "noop" builds. On my laptop, 'ninja -C build' that does nothing goes from 0.1 to 0.5 s. It would be nice to avoid this, but I think that <1 s is still acceptable. Fixes #7183. PACKAGE_VERSION is renamed to GIT_VERSION, to make it obvious that this is the more dynamically changing version string. Why save to a file? It would be easy to generate the version tag using run_command(), but we want to go through a file so that stuff gets rebuilt when this file changes. If we just defined an variable in meson, ninja wouldn't know it needs to rebuild things. --- meson.build | 5 ++++- src/analyze/analyze.c | 3 ++- src/basic/build.h | 2 ++ src/basic/meson.build | 5 +++++ src/basic/util.c | 2 +- src/basic/version.h.in | 1 + src/boot/efi/boot.c | 8 ++++---- src/boot/efi/meson.build | 4 ++-- src/boot/efi/stub.c | 4 ++-- src/core/dbus-manager.c | 2 +- src/core/main.c | 4 ++-- src/import/curl-util.c | 3 ++- src/journal-remote/journal-upload.c | 3 ++- src/test/test-libudev.c | 3 ++- src/test/test-udev.c | 3 ++- src/udev/scsi_id/scsi_id.c | 3 ++- src/udev/udevadm.h | 4 +++- src/udev/udevd.c | 5 +++-- tools/meson-vcs-tag.sh | 9 +++++++++ 19 files changed, 51 insertions(+), 22 deletions(-) create mode 100644 src/basic/version.h.in create mode 100755 tools/meson-vcs-tag.sh diff --git a/meson.build b/meson.build index 7816ba9949..100265570d 100644 --- a/meson.build +++ b/meson.build @@ -21,7 +21,6 @@ libudev_version = '1.6.11' # set.
