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 062c80c1ac start enforcing a mininum number of elms in pools. 2018-10-30 10:41:49 +01:00
Joris Vink 71c145932c grow kore_pools at a slower rate. 
Before we just doubled in size the second we exhausted a pool instead
of doing a more controlled expansion.

Now we will expand at 25% of the initial elm count whenever we need to.

Will help with memory pressure in certain scenarios.

Joris Vink ae2ea0be72 specify what openssl versions are expected to work. 2018-10-30 08:45:11 +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.

Joris Vink 740acb4760 make sure we can still build vs 1.1.0 2018-10-29 21:11:29 +01:00
Joris Vink 818c7847cd simplify even more 2018-10-29 20:43:40 +01:00
Joris Vink ae72b21d35 make sure older openssl/libressl builds work. 2018-10-29 20:42:28 +01:00
Joris Vink 339df66fd5 Add support for TLS 1.3 via OpenSSL 1.1.1. 
This commit removes TLS 1.0 support no matter what OpenSSL
you are linking against.

Changes the value of tls_version from 1.2 to both. Meaning if
you link with OpenSSL 1.1.1 you will get 1.2 + 1.3.

Joris Vink dda2e1fb2c Some things still talk http/1.0. 2018-10-26 21:24:51 +02:00
Joris Vink fc246e5552 defaults were changed 2018-10-26 19:24:51 +02:00
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 ea7ea48840 actually just query for HW_NCPU on all BSDs. 2018-10-25 19:31:48 +02:00
Joris Vink 9d9e9dcec2 set cpu_count to 1 for unknown BSDs 2018-10-25 19:30:10 +02:00
Joris Vink 892814e353 Add kore_[parent|worker]_teardown(). 
If exists these functions are called when the worker is exiting
and when right before the parent exists.

Allows for cleanup code for applications if need to do cleanup on exit.

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'')

Joris Vink 4c35073232 Use number of cpu cores if no worker count is set. 2018-10-22 21:27:17 +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 c8795b7d7f pyqueue improvements. 
- cleanup queue if it gets deallocated.
- make sure waitables on a queue get removed if their pyqueue_op dies.

crypto library Kore would link with.
 2018-10-17 11:31:36 +02:00
Joris Vink c172d49567 kodev improvements.

Joris Vink 6080bb1c35 echo server example in Python with new async/await. 2018-10-15 20:37:51 +02:00
Joris Vink 545d48e65d revert chunk that wasn't suppose to be changed. 2018-10-15 20:33:34 +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().

Joris Vink c12f296743 missing EPOLLRDHUP check since event loop rework 2018-10-10 14:33:26 +02:00
Joris Vink c463ecb3cb Changes to the event loop inside of Kore. 
Now anyone can schedule events and get a callback to work as long
as the user data structure that is added for the event begins
with a kore_event data structure.

All event state is now kept in that kore_event structure and renamed
CONN_[READ|WRITE]_POSSIBLE to KORE_EVENT_[READ|WRITE].
