Zbigniew Jędrzejewski-Szmek d9f644e2cd bus: export libsystemd-bus as a public library 
Old static libsystemd-bus.la becomes libsystemd-bus-internal.la.
memfd functions are also exported in the same library.

(Best viewed with --color-words -U0).

Lennart Poettering cd6f997f71 bus: handle serialization of NULL strings 
Instead of simply crashing be somewhat nicer and serialize a NULL string
into the empty string and generate an error on signature and object path
strings.

Lennart Poettering 7b05894275 bus: add new bus API call sd_bus_message_at_end() 
This may be used to determine whether we are at the end of a container
ot the entire message.

Lennart Poettering 9d6c7c821c bus: make use of assert_return() in all API calls that don't use it yet 2013-11-05 19:14:58 +01:00
Marc-Antoine Perennou 4686d1b6ee bus: add sd_bus_message_read_strv() 
It will be useful to have that in the public API.

Lennart Poettering 0dcd14b940 bus: allow that if the destination pointer in sd_bus_message_read_basic() is NULL we skip over a field 2013-11-05 02:26:48 +01:00

Lennart Poettering 430fb8fab2 bus: only if the user tries to read over the end of an array we should handle this as EOF 2013-10-22 12:41:54 +01:00
Kay Sievers 9bcbce4201 bus: avoid 'bool' storage when retrieving 'b' from the message 
Just use an unsigned int as a bool type to avoid issues in the public
message reading API; sizeof(bool) == 1, but the code copies 4 bytes at
the pointers destination.

Lennart Poettering 1daf812152 bus: if we hit the end of an array container return 0 as EOF indicator when reading it 2013-10-18 14:07:44 +02:00
Lennart Poettering 40ca29a137 timedated: use libsystemd-bus instead of libdbus for bus communication 
Among other things this also adds a few things necessary for the change:

- Considerably more powerful error returning APIs in libsystemd-bus

- Adapter for connecting an sd_bus to an sd_event

- As I reworked the PolicyKit logic to the new library I also made it
  asynchronous, so that PolicyKit requests of one user cannot block out
  another user anymore.

- We always use the macro names for common bus error. That way it is
  harder to mistype them since the compiler will notice

Lennart Poettering 55736ed0c7 bus: add sd_bus_message_append_strv() to easily add a NULL terminated string array to a message 2013-10-11 23:02:47 +02:00

Lennart Poettering 29ddb38fea libsystemd-bus: add lightweight object vtable implementation for exposing objects on the bus 
This adds a lightweight scheme how to define interfaces in static fixed
arrays which then can be easily registered on a bus connection. This
makes it much easier to write bus services.

This automatically handles implementation of the Properties,
ObjectManager, and Introspection bus interfaces.

Kay Sievers bf30e48fe5 bus: unmap memfd retrieved from the memfd cache 2013-06-04 23:37:57 +02:00
Kay Sievers 311754514c bus-benchmark: add performance data output mode 
- for now, comment out munmap() check to enable memfd passing
  - print tab-separated values and header
  - add memcpy() to fill the memfd, to produce real-world results

Lennart Poettering f54514f354 bus: keep kernel bus fd around during entire life-time of bus 
We need this since we might need to invoke the release ioctl for
messages. Since we don't want to add any locking for that we simply keep
a reference to the bus and then rely that the fd stays valid all the
time.
