2013-11-28bus: add new sd_bus_creds object to encapsulate process credentialsLennart Poettering
This way we can unify handling of credentials that are attached to messages, or can be queried for bus name owners or connection peers. This also adds the ability to extend incomplete credential information with data from /proc, Also, provide a convenience call that will automatically determine the most appropriate credential object for an incoming message, by using the the attached information if possible, the sending name information if available and otherwise the peer's credentials.
2013-11-28event: allow EPOLLET as event flagDavid Herrmann
EPOLLET enables edge-triggered mode (see epoll(7) for more). For most use-cases, level-triggered is just fine, but for master-TTYs we need edge-triggered to catch EPOLLHUP. master-TTYs signal EPOLLHUP if no client is connected, but a client may connect some time later (same happens during vhangup(2)). However, epoll doesn't allow masking EPOLLHUP so it's signaled constantly. To avoid this, edge-triggered mode is needed.
2013-11-28bus: add bus_name_has_owner() helperDavid Herrmann
Small helper to run a synchronous "NameHasOwner" request on the dbus-daemon.

2013-11-22bus: rework sd_bus_error APIsLennart Poettering
All calls that set a sd_bus_error structure will now return the same error converted to a negative errno. This may be used as syntactic sugar to return from a function and setting a bus_error structure in one go. Also, translate all Linux Exyz (EIO, EINVAL, EUCLEAN, EPIPE, ...) automatically into counterparts in the (new) "Posix.Error." namespace. If we fail to allocate memory for the components of a sd_bus_error automatically reset it to an OOM error which we always can write.

2013-11-21bus: rework message handlers to always take an error argumentLennart Poettering
Message handler callbacks can be simplified drastically if the dispatcher automatically replies to method calls if errors are returned. Thus: add an sd_bus_error argument to all message handlers. When we dispatch a message handler and it returns negative or a set sd_bus_error we send this as message error back to the client. This means errors returned by handlers by default are given back to clients instead of rippling all the way up to the event loop, which is desirable to make things robust. As a side-effect we can now easily turn the SELinux checks into normal function calls, since the method call dispatcher will generate the right error replies automatically now. Also, make sure we always pass the error structure to all property and method handlers as last argument to follow the usual style of passing variables for return values as last argument.

2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.

2013-11-20event: clear pending-state when re-arming timersDavid Herrmann
If a timer fires and is marked pending, but an application re-arms it before it is dispatched, we now clear the pending state. This fixes a bug where an application arms a timer, which fires and is marked pending. But before it is dispatched, the application loses interest in it and disables it. Now if the timer is re-armed and re-enabled later, it will be immediately dispatched as it is still marked pending. This behavior is unexpected, so avoid it by clearing pending state when re-arming timers. Note that applications have no way to clear pending state themselves, so there's no current workaround.
2013-11-20bus: fix error-path in bus_map_all_properties()David Herrmann
We shouldn't return positive integers on errors. Fix the typo by removing the negation.

2013-11-12build-sys: add a link test for exported symbolsZbigniew Jędrzejewski-Szmek
I know that this is a pretty big net to catch some small fish, but we *do* regularly forget to properly export symbols that were supposed to be exported. This time sd_bus_get_current and some renamed symbols are caught.
