Joris Vink ec7c8b8e1d fix a few minor problems with pylock. 
- when pylocks are deallocated we ended up deleting the wrong object.
- do not call Py_DECREF on the op when inside the op its iternext call.

Joris Vink b06160c768 Make sure coros are woken up on eof. 2019-03-13 15:45:55 +01:00
Joris Vink 3b4574d791 Rework pysocket async/await. 
Attach the events directly to the pysocket data structure instead of
one event per pysocket_op.

Makes the code easier, gives us a good performance boost and reduces
the number of system calls required when doing an await on a socket.

Joris Vink c431c2bf72 Add support to obtain peer certificate from Python 
This will return the DER encoded bytes representing the peer certificate.
 2018-11-28 11:28:07 +01:00
Joris Vink 5c8efde841 allow foo.method symbols in python. 
this way you can create page handlers that reside inside
of other objects.

eg:

static / restapi.index
 2018-11-16 11:07:21 +01:00
Joris Vink cb482d8e8f Always use http_response_stream() in req.response. 
Keep around the python bytes object while we stream the contents
of it out over the wire. This avoids an entire copy of the data.
 2018-11-14 10:03:32 +01:00
Joris Vink 3925ba60ad don't call close() no underlying socket. 2018-11-12 09:00:36 +01:00
Joris Vink 4cc9e216bb Don't call close() on the python socket on dealloc 2018-11-06 16:54:26 +01:00
Joris Vink 2dd66586ff several python improvements. 
- add kore.time() as equivalent for kore_time_ms().
- call waitpid() until no more children are available for reaping otherwise
  we risk missing a process if several die at the same time and only one
  SIGCHLD is delivered to us.
- drain a RECV socket operation if eof is set but no exception was given.

Joris Vink 5456f2e1d5 save/restore coro_running in pygather_op_dealloc(). 2018-10-30 12:37:30 +01:00
Joris Vink bb00deca2c don't leak op in error path 2018-10-29 21:18:38 +01:00
Joris Vink 1c30da855c Add kore.gather() to the python api. 
Allows one to run coroutines concurrently and gather all their
results in a single returned list.

If any of the coroutines throw an exception the exception is
returned as the value of that coroutine in the returned list.
 2018-10-29 21:16:08 +01:00
Joris Vink e2651889e0 Add asynchronous subprocess support. 
This adds kore.proc to the python runtime allowing async processing
handling:

The kore.proc method takes the command to run and an optional timeout
parameter in milliseconds. If the process did not exit normally after
that amount of time a TimeoutError exception is raised.

For instance:

async def run(cmd):
	proc = kore.proc(cmd, 1000)

	try:
		await proc.send("hello")
		proc.close_stdin()
	except TimeoutError:
		proc.kill()

	retcode = await proc.reap()

	return retcode

Joris Vink fc5fc4f4ab make sure timers don't go out of scope. 2018-10-23 21:36:19 +02:00
Joris Vink 8ea32983ae Add kore.suspend(delay) to python. 
Will suspend the coroutine for a number of milliseconds.

Example:

async def page(req):
	await kore.suspend(1000)
	req.response(200, b'')
 2018-10-23 21:32:08 +02:00
Joris Vink 47776a9fbb Hook kore timers into python. 2018-10-23 20:44:43 +02:00
Joris Vink c41c1db303 Add kore_shutdown(). 
Allows workers to cleanly initiate a shutdown of the
entire server process.
 2018-10-23 19:49:42 +02:00
Joris Vink b70d1ee80f Add a locking mechanism in pykore. 
Support the async with syntax:

	lock = kore.lock()

	async with lock:
		# your block

Fix some small issues with other parts of the python system.

Joris Vink fad5c6ea6f Give pyqueues "popnow". 2018-10-22 08:28:03 +02:00
Joris Vink c8795b7d7f pyqueue improvements. 
- cleanup queue if it gets deallocated.
- make sure waitables on a queue get removed if their pyqueue_op dies.

Joris Vink 4ae3d23c7e s/INCREF/DECREF 2018-10-18 22:24:58 +02:00
Joris Vink 0cda9ecfb0 Add an asynchronous queue mechanism. 
This allows coroutines to submit messages to and pop
messages from a queue in an asynchronous way.
 2018-10-18 22:15:21 +02:00
Joris Vink 300daeadef fix comment 2018-10-16 13:17:44 +02:00
Joris Vink 29202d7330 Make kore_python_log_error() public. 
While here also make kore_module_load() return the
kore_module data structure pointer it just added
to the modules list.
 2018-10-16 13:16:36 +02:00
Joris Vink 20a0103f1e Add async/await support for socket i/o in python. 
This means you can now do things like:

	resp = await koresock.recv(1024)
	await koresock.send(resp)

directly from page handlers if they are defined as async.

Adds lots more to the python goo such as fatalx(), bind_unix(),
task_create() and socket_wrap().
