2012-01-16dbus: more efficient implementation of propertiesMichal Schmidt
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.
2012-01-16unit: remove union UnitMichal Schmidt
Now that objects of all unit types are allocated the exact amount of memory they need, the Unit union has lost its purpose. Remove it. "Unit" is a more natural name for the base unit class than "Meta", so rename Meta to Unit. Access to members of the base class gets simplified.

2011-03-09dbus: fix dbus assert due to uninitialized errorAndrey Borzenkov
Add missing dbus_error_init() in UNKNOWN_OBJECT case. Fixes assertion systemd[1]: Caught <ABRT>, dumped core as pid 6256. systemd[1]: Freezing execution. Core was generated by `/bin/systemd systemd.unit=graphical.target'.

2010-11-23build-sys: allow cross-compilationThierry Reding
When cross-compiling systemd, the introspection XML files fail to be generated because the systemd host binary is not executable. This patch works around this by putting the introspection XML data into separate ELF sections and extracting them from the binary when generating the XML files. The extracted XML data is passed through the strings utility in order to strip the trailing NUL character. A small AWK script is used to prepend the doctype and add the opening and closing node tags respectively. Finally, the C preprocessor is used to substitute the correct doctype information from the D-Bus header files.

2010-07-20device: do not merge devicesLennart Poettering
Don't try to merge devices that have been created via dependencies when they appear in the system and can be recognized as the same. Instead, simply continue to maintain them independently of each other, however with the same state cycle. Why? Because otherwise we'd have a hard time to seperate the dependencies after the devices are unplugged again and we hence cannot be sure anymore that next time the device is plugged in it will carry the same names. Example: if one depndency refers to dev-sda.device and another one to dev-by-id-xxxyyy.device we only learn at time of plug in of the device that it is actually the same device that was ment. In the moment the device is unplugged again we won't know anymore their relation to each other and the next time the harddisk is plugged it might even appear as dev-by-id-xxxyyy.device and dev-sdb.service. To ensure the dependencies continue to have the meaning they were intended to have let's hence keep the .device objects seperate all the time, even when they are plugged in. This patch also introduces a new Following= property which points from the various .device units of a specific device to the main .device unit for it. This can be used by the client side to figure out the relation of the .device units to each other and even filter units from display.
