[fuse-devel] FUSE Python: Thread initialization and destruction functions

[Nikolaus R. <Nik...@ra...>]

Hello,

I was wondering if it would be possible to add thread-specific
initialization and finalization functions to FUSE Python. They should
be called whenever a thread is created and destroyed.

One can already perform thread initialization by check if thread local
variables have been set:

class fs(fuse):
    def __init__(self):
        fuse.__init__();

        self.local = thread.local()

    def initi_thread(self):
        self.local.somedata = something
        ....
       

    def getattr(self, path):
        if not hasattr(self.local.somedata):
           self.init_thread()


but this is a bit clumsy since the last lines have to be added to
every FUSE operation. Moreover, there is currently no way to execute
code when a thread is finalized. In the C API one can define a
destructor using pthreads_key_create, but this is not possible in
Python.

Csaba, what do you think about the idea?


Best,


   -Nikolaus
