Martin Willi c3b8335cfb NEWS: mention watcher and stream services 2013-07-18 16:10:48 +02:00
Martin Willi 666dff70eb Merge branch 'ipc-service' 
Adds network transparency and TCP support to the IPC interfaces of different
plugins using the new stream and stream service classes. A central watcher
thread can watch multiple file descriptors to handle connection requests
for these and other services using only a single thread.

Martin Willi b4b3959b22 stream-service: move CAP_CHOWN check from plugins to service constructor 
A plugin service can be a TCP socket now, so it does not make much sense
to strictly check for CAP_CHOWN.

Martin Willi ea009869e9 watcher: use processors new execute_job() to notify FDs 
Just queueing is problematic, as all threads might be busy waiting for events
that the queued (but never executed) job delivers.

Martin Willi 6653e6c13e processor: add an execute_job() method to directly execute an important job 
If all worker threads are busy and waiting for an event, we must ensure that
a job delivering that event gets executed. This new method has this property
for CRITICAL jobs, using a worker if we have one, but executing the job directly
if not.

Martin Willi 55240835b0 watcher: properly support multiple watch callback types for the same FD 2013-07-18 16:00:31 +02:00
Martin Willi d0c25a3f23 watcher: read multiple notifications if available 
Use non-blocking I/O on the read end of the notify pipe. This also makes sure
the read does not block should select() signal data while there is none.

Martin Willi 0a35ae781d whitelist: use a read-copy when listing entries 
While this requires a little more overhead, we can free the lock should the
stream block, allowing other threads to add/remove entries.

Martin Willi e11c02c8f1 whitelist: use a stream service to accept client connections 
Use SOCK_STREAM, as we don't have SOCK_SEQPACKET on TCP. To have network
transparency, the message now uses network byte order.
 2013-07-18 16:00:29 +02:00
Martin Willi 091d0afa21 lookip: use stream service with async I/O dispatching 
Now uses SOCK_STREAM, as SOCK_SEQPACKET is not available over TCP. To have
network transparency, the message now uses network byte order.
 2013-07-18 16:00:29 +02:00
Martin Willi c2a6fdf286 error-notify: use a stream service to accept client connections 
As TCP does not have SOCK_SEQPACKET, we now use SOCK_STREAM for the error-notify
socket. To have network transparency, the message now uses network byte order.

Martin Willi 83faec5abe duplicheck: use a stream service to accept client connections 
As we can't use SOCK_SEQPACKET over TCP, we now have to provide message
boundaries ourselves. We do this by appending a 16-bit length header to each
sent duplicate identity.

Martin Willi 91a2ae644c watcher: if the processor has no threads, execute the job with watcher thread 
This is important during shutdown, where we might need to signal some FDs while
all idle threads are gone already.

Martin Willi 50720d7ce9 processor: add a getter for the threads passed to set_threads() 2013-07-18 16:00:29 +02:00
Martin Willi a0e3a7363f watcher: unregister a watcher FD if its thread gets cancelled 2013-07-18 16:00:29 +02:00
Martin Willi a558ba16f3 watcher: release threads waiting in remove() when watcher thread gets cancelled 
During daemon shutdown, users might call remove() after processor.set_threads(0)
has been called. This gets problematic, as a watch event might be unable
to signal completion when no threads are available anymore. Work around this
issue by cancelling waiters once processor.cancel() has been called.

Martin Willi 047a190600 stream: use a service constructor to create services 
It does not make much sense to reference running services in the manager,
especially as unregistration would need the URI (which a user would have to
store instead of the service reference).
 2013-07-18 16:00:28 +02:00
Martin Willi fbdc65debb stream: replace print/vprint() convenience functions by a FILE* getter 
While this will complicate the implementation of streams not based on a fd,
it allows us to unleash the full power of FILE based convenience functions.
