[issue25293] Hooking Thread/Process instantiation in concurrent.futures.

2017-11-02 Thread Antony Lee 

Antony Lee  added the comment:

I can't say I *really* need this anymore, but note that 
https://bugs.python.org/issue21423 is less general as it does not handle the 
case of a finalizer as proposed here.

[issue25293] Hooking Thread/Process instantiation in concurrent.futures.

2015-10-01 Thread Antony Lee 

New submission from Antony Lee:

http://bugs.python.org/issue21423 and http://bugs.python.org/issue24980 suggest 
adding an initializer/on_new_thread argument to {Thread,Process}PoolExecutor.  
I would like to suggest a more unified API, that would allow not only handling 
initialization, but also finalization, by adding a {thread,process}_class 
attribute / constructor argument to {Thread,Process}PoolExecutor, so that one 
could do:

class MyThread(Thread):
def run(self):
initialize()
try: super().run()
finally: finalize()

with ThreadPoolExecutor(thread_class=MyThread): ...

Thoughts?
