Calvin Rose e76b8da269 Add semantics for closing channels. 
This makes certain algorithms simpler as channels
now have an explicit lifetime - multiple readers can coordinate
closing without needing to ensure the same number of reads as writes.

Calvin Rose eb84200f28 Fix linux issues with epoll on normal files.

register a file descriptor.

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.

bakpakin 202783c67a Add :d switch to os/spawn. 
This allows for starting processes that can be turned into zombies.

Calvin Rose e7ea39f410 Prevent possible bad garbage collection when finalizing streams. 
The GC finalizer for streams would sometimes try and use other objects
after they had already been freed.

themselves.

Calvin Rose a1cc5ca045 Fix #593. 
Also add ev/give-supervisor to the core.
 2021-01-16 07:18:07 -06:00
Calvin Rose 4f2d1cdc00 Go back to a single supervisor channel per fiber. 
We now also use the fiber mask to figure out which flags to wait for.
 2021-01-12 21:35:28 -06:00

Minor typo in ev/rselect docstring 
`ev/choice` is actually called `ev/select`

Calvin Rose 7ae7984f3c Allow yielding from root fiber to ev loop. 2021-01-09 23:35:34 -06:00
Calvin Rose 8286b33c52 Add event-chan argument to ev/go. 
The event-chan is the final piece of the puzzle for fibers, and
will be pushed to when a fiber yields to the event loop.
 2021-01-09 23:33:23 -06:00
Calvin Rose 475775cc9d Add a "new_channel" for root fibers. 
When new fibers are scheduled on the event loop, this new_channel
receives the newly created fibers. This lets a fiber track which fibers
have been added and let's a user implement a supervisor.

Fix formatting.

Calvin Rose 444e630783 Fix formatting. 2021-01-09 10:14:20 -06:00
Calvin Rose 8951b8de7a Inherit the supervisor channel from the root fiber if not given. 2021-01-08 16:32:23 -06:00
Calvin Rose 4e7ad3c7ce Add initial implementation for supervisor channels. 
Supervisor channels are a simple concept to more efficiently
enable dynamic, structure concurrency. When a top-level fiber
completes (or errors), it will push itself to it's supervisor
channel if it has one (instead of printing a stacktrace). This
let's another fiber poll a channel and "supervise" a set of fibers.
