Calvin Rose 3bc42d0d37 Only re-register when using poll. 2024-02-19 13:19:23 -06:00
Calvin Rose 12630d3e54 Register stream on unmarshal 2024-02-19 13:16:45 -06:00
Calvin Rose c9897f99c3 Address #1405 - don't try and resume fibers that can't be resumed. 
FOr fibers that _can_ be resumed and then get cancelled, the sched_id
will be incremented later prevent the spurious wake ups.

Calvin Rose a10b4f61d8 Address #1337 (leet!). 
Changes a few scheduling details and adds a 0 byte explicitly to
symbols created via gensym.

Ico Doornekamp 9b640c8e9c net/ev: Cleaned up unused NetStateConnect, fixed janet_async_end() ev refcount 2023-11-10 20:34:17 +01:00
Calvin Rose 3b189eab64 Fix #1321, poll event loop CPU usage issue 
A stream may have a fiber attached for memory management purposes, but
not actually be waiting on anything. Be more seletive with poll, which
is not edge-triggered, to not poll for readiness on these streams.

Calvin Rose 4139e426fe Refine interface for janet's new event loop.

Calvin Rose fea8242ea7 Reuse overlapped overhead on windows for something useful. 2023-10-07 11:25:20 -07:00
Calvin Rose 7bfb17c209 Lots of work to make iocp work again. 
Big issue with IOCP vs. poll variants is that the overlapped
structures have a longer lifetime than intermediate state needed
for epoll. One cannot free overlapped structures after closing a
handle/socket, like one can do with any intermediate state when using
readiness-based IO.

Calvin Rose b6e3020d4c Attempt 2 to fix bsd compilation errors. 2023-10-04 23:27:56 -05:00
Calvin Rose 8f516a1e28 Address some bsd issues. 2023-10-04 23:24:40 -05:00
Calvin Rose 5f2e287efd Make epoll event loop use EPOLLET and not reregister file descriptors. 
This results in fewer system calls and presumably more effcient code. It
also brings the epoll (and kqueue) code more in line with how the
windows IOCP code works, incidentally.
 2023-10-04 22:35:04 -05:00
Calvin Rose 2ea90334a3 Remove some checking code for iocp events. 
Be more permissive abouts events we get.
 2023-10-02 23:25:26 -07:00
Calvin Rose eea8aa555f Revert dccb60b to address #1299 
This commit was to address issues with a use after free error in the
windows event loop, but the erroneous code was later reworked.

This code was duplicate in a few places.

Calvin Rose 81f35f5dd1 Redo state management for Janet listeners. 
Make more use of the built in GC code for abstracts to
be sure things are more correct. Issue before was streams could
be freed before IOCP events arrived.
