uasyncio.core: Remove call_at() which takes absolute second time.
...
uasyncio uses different timebase than CPython's asyncio, so absolute
time scheduling compatible with it is impossible. Instead, there's
call_at_() which schedules using modular millisecond time.

It's unused since since sleep() was switched to yield an integer for
delay.

uasyncio.core: Fix scheduling in the presense of I/O completion callbacks.
...
wait() may finish prematurely due to I/O completion, and schedule new,
earlier than before tasks to run. So, after call to wait(), we need to
check current time and time of head task, and continue to wait if needed.
Recently introduced provisional utimeq.peektime() is used to optimize
querying time of a head task.

uasyncio.core: Set lower default queue len and allow to override it.
...
The default is set to be under 0.5K on 32-bit system. A queue length
can be passed to get_event_loop() to override it.

222758f0c2
uasyncio.core: Switch to dedicated utimeq class.
...
Allows zero-allocation scheduling of tasks. As long as tasks don't use
await/yield from with coroutines, and don't allocate memory themselves,
there will be no allocation and GC.
2016-12-22 13:04:09 +03:00

uasyncio.core: create_task: Fix scheduling.

Should start with zero delay, not at zero absolute time.

uasyncio.core: Add additional debug output control.
...
__debug__ isn't flexible enough, if you don't disable it, there's huge
memory allocation.

02a6625a00
uasyncio.core: Introduce "trailing _" functions which avoid arg un/packing.
...
They just take tuple of arguments instead of *args. In most cases, that
will be () singleton.

This makes uasyncio.core compatible with baremetal/embedded ports.
Includes switching to "uheapq timeq" for task queue.

uasyncio.core: call_soon(): Use current time, not zero time.
...
Using static zero time may become a problem when using wrap-around time
sources, like utime.ticks_ms().

uasyncio.core: Optimize case of resuming coro with no args.
...
Don't create a new tuple with empty arguments for coro.send(), just use
next(coro).

uasyncio.core: async() was renamed to ensure_future() upstream.
...
The old name is deprecated since CPyton 3.4.4. That's great relief, because
CPython has special parser hacks to support both 3.5-style "async" keyword,
and still allow it be used as an identifier in other contexts. MicroPython
lacks such hacks, so "async" is SyntaxError as a function name with the latest
versions which implement async keyword.

uasyncio.core: Avoid wrapping coroutines to lambdas for add_reader/writer.
...
add_reader/writer default behavior is to schedule "callback" on I/O
completion via call_soon(), there's no need to have lambda for that.

460dd59b16
uasyncio.core: Don't pass any callback args to add_reader/add_writer.
...
Instead, capture all needed param in closure. Due do bug in MicroPython's
handling of default args to lambdas, helper function is used.

uasyncio.core: Implement EventLoop.create_task(), new method in Python 3.4.2.

This method allows to schedule a coroutine in a loop without confusing globals
like async() or Task().
