sogaiu 8365037be5 Update os.c with new style core function declarations. 2021-07-26 16:48:04 +09:00
bakpakin 6f1695ecd4 Add utitities for interrupting the event loop. 
janet_loop1_interrupt makes the event loop compatible
with safe interruptions for custom scheduling. Does this by exposing
custom events on the event loop. A custom event schedules a function pointer
to run in a way that can interrupt
epoll_wait/poll/GetQueuedCompletionStatus.

This fixes windows hanging on "failed" IO operations.
 2021-01-17 20:41:59 -06:00
Calvin Rose 462e74ef87 Add os/proc-close to close all pipes associated with a subprocess.

Calvin Rose bf01bf631d More work on windows networking code. 
Remove use of WSARecv and WSASend since for whatever reason
they seem suspect. We may want to revisit this later.

Calvin Rose 47bb7fd21b Begin implementing async subproccesses for windows. 2021-01-03 11:21:44 -06:00
Calvin Rose 1c7ed8ca48 Use PostQueuedCompletionStatus for threaded calls on windows. 
Ore efficient than using a self pipe.
 2021-01-03 11:08:12 -06:00
Calvin Rose 05166b3673 Fix proc getter bug. 2020-12-31 16:23:20 -06:00
Calvin Rose 0a1c93b869 Add ev api for making threaded calls. 
Easy way to make arbitrary functions in C async.
 2020-12-31 16:12:42 -06:00
Calvin Rose 788f91a36f Remove unneeded book keeping for sub processes. 
Since we are not using signals we no longer need some bookkeeping.
 2020-12-31 11:52:12 -06:00
Calvin Rose c831ecf5d2 Working implementation of process waiting with threads. 
Does not require all sorts of signal handling code
that is not thread-safe and can "steal processes".

However, there is a much simpler way to add this functionality
by creating a new stream and thread for each subprocess when it is
waited on. This is perhaps _slightly_ less efficient but oh so much
simpler, since we can reuse all of our concepts from streams and there
is no need to implement a whole system around the selfpipe.

Calvin Rose 9e42ee153c Merge branch 'master' into HEAD 2020-12-30 12:19:13 -06:00

Calvin Rose d53007739e Invert read/write bits on pipe in os/execute. 
It was backwards, breaking this functionality.
 2020-12-09 19:04:05 -06:00
Calvin Rose cbdea8f331 Make os/execute cooperate with ev module. 
os/execute, os/proc-wait do not block (currently posix only).
This uses the self-pipe trick to turn signals into a pollable entity.
 2020-11-29 15:36:21 -06:00
Calvin Rose 53aa19a916 Several changes to move pipe creation back into ev.c 2020-11-18 10:53:36 -06:00
