The way the various properties[] arrays are initialized is inefficient:
- only the .data members change at runtime, yet the whole arrays of
properties with all the fields are constructed on the stack one by
one by the code.
- there's duplication, eg. the properties of "org.freedesktop.systemd1.Unit"
are repeated in several unit types.
Fix it by moving the information about properties into static const
sections. Instead of storing the .data directly in the property, store
a constant offset from a run-time base.
The small arrays of struct BusBoundProperties bind together the constant
information with the right runtime information (the base pointer).
On my system the code shrinks by 60 KB, data increases by 10 KB.
This patch adds support for the Mageia Linux distribution:
http://www.mageia.org/
Mageia is a fork of Mandriva although some divergence has already occured
and thus inclusion of these changes upstream allow us to (hopefully)
migrate more rapidly to the new standard approaches systemd offers.
Indeed, we already use the preferred mechanism of OS identification via
the /etc/os-release file rather than a distro specific variation.
This patch mostly mirrors the patch added previously for Mandriva
support. In addition to those original authors, this patch was mostly
written by Dexter Morgan with help from Colin Guthrie and Eugeni Dodonov.
<mbiebl> kay, mezcalero: https://bugzilla.gnome.org/show_bug.cgi?id=627789
<mezcalero> so we can drop that entirely?
<mezcalero> kay: if you drop those two lines, does it improve things for you?
<mbiebl> kay: but ./configure should work now
<mbiebl> resp. autogen.sh
<kay> mezcalero, mbiebl: autogen.sh seems a lot better without the two lines
<kay> mezcalero: works without the 'touch' thing
<mezcalero> kay: ok, commit please
As in the bug[1] it would be nice to configure plymouth support
independently of the distro. This patch adds a "--enable-plymouth" and
"--disable-plymouth" option to the configure script to overwrite the
distro specific default.
