Calvin Rose aa0de01e5f Fix some formatting and undefined behavior. 2020-12-06 14:33:08 -06:00
Calvin Rose 9d23192614 Add ev/deadline and ev/with-deadline. 
This should be more useful than timeouts in real-world
use cases. The deadline system is based on fibers and is target
to much more coarse-grained (and therfor reliable) timeouts than things
like ev/sleep and timeout arguments.
 2020-12-05 10:32:34 -06:00
Calvin Rose a0964d44d5 Fix some valgrind errors. 
A null pointer dereference and a memory leak with the line/col mapping.
 2020-11-27 12:21:23 -06:00
Calvin Rose ca7c5b8b10 ev/call uses current env as prototype of environment. 2020-11-26 21:13:41 -06:00
Calvin Rose 6c43489fb2 Fix #508 - nil fiber environment. 
run-context did not handle a nil environment well, so that was fixed
and ev/call inherits the environment when creating the fiber.
 2020-11-26 19:04:45 -06:00
Calvin Rose a3e812b86d Fix #505 - bat int64 parsing. 
Fixes an off-by-1 error.

Also makes windows testing hopefully a bit less flaky.

Calvin Rose a3f98091c4 Fix #509 
janet_fiber returns NULL if there is a bad arity, check that before
continuing.
 2020-11-23 15:28:28 -06:00
Calvin Rose 53aa19a916 Several changes to move pipe creation back into ev.c 2020-11-18 10:53:36 -06:00
Calvin Rose cff52ded58 Add JANET_ASYNC_EVENT_CANCEL 
also fix bug that could cause event loop to hang.

Calvin Rose 078f50d45a When reading from a stream, EPIPE is considered EOS. 
Before, EPIPE caused an error, but in most cases it is better
to consider it an end of stream. In the future, we may want to allow
cusomtization of this behavior with flags on the stream but for now
let's keep it simpler.

Calvin Rose 9ec5689d6b Don't use gcroot/unroot for tracking IO operations. 
This could have bad effects in higher load situations, and
duplicates code. It is better to keep a dedicated list of
scheduled IO operations which can be efficiently added and
removed from. It also provides and easy way to enumerate
scheduled IO operations.

Calvin Rose a25b030e36 Fix EPOLL implementation. 2020-11-15 19:40:47 -06:00
Calvin Rose d7af4596e1 Move math.h include out of windows ifdef 2020-11-15 10:21:37 -06:00
Calvin Rose a7ed3dea4b Remove some flags in os/open. 2020-11-15 10:06:20 -06:00
Calvin Rose cdcb774dc8 Add os/pipe and os/open. 
ev/pipe -> os/pipe, and os/open is a wrapper
around the open system call.
 2020-11-15 09:57:29 -06:00
Calvin Rose d199c817dc Broken Pipe error on windows should just be end of stream. 2020-11-14 16:03:51 -06:00
Calvin Rose 139e3fab25 Invert status check for (Read/Write)File 2020-11-14 15:52:01 -06:00
Calvin Rose 7a98f9aa02 Improve windows error messages on write failures. 2020-11-14 15:48:21 -06:00
Calvin Rose b53dd67e74 Use custom pipe implementation for overlapped io. 2020-11-14 15:44:19 -06:00
Calvin Rose d50c4ef6da Try again for windows build. 2020-11-14 15:01:52 -06:00
Calvin Rose 7d0b1955a2 typo 2020-11-14 14:55:26 -06:00
Calvin Rose 16cf7681f0 Fix some windows issues. 2020-11-14 14:40:39 -06:00
Calvin Rose 12f09ad2d7 Add ev/pipe and move stream code into ev.c 
Also adds a lot to the C API and changes things up.
 2020-11-14 14:29:11 -06:00
Calvin Rose b3e88a8d80 Move read/write functions into ev.c from net.c 
This code can also be used for non-network streams.
 2020-11-14 11:48:23 -06:00
Calvin Rose caa6576719 Fix formatting. 2020-11-11 15:35:44 -06:00
Calvin Rose 56b1ea3726 Include math.h to fix some bugs on 32 bit windows. 2020-11-08 19:06:35 -06:00
Calvin Rose d6391f2d70 Get windows IOCP working for accept. 
This also changes the api of servers slightly -
in light of having support for ev tasks, it is probably better
to remove the "simple" server code and replace it with some Janet
or remove it all together. While convenient, it has issues with error
handling and rigidity.
 2020-11-08 18:56:13 -06:00
Calvin Rose 07910272e2 Get socket reads and writes working with IOCP. 2020-11-08 10:38:28 -06:00

Calvin Rose 88c1cf3ee7 Reformat files. 2020-10-11 09:33:07 -05:00
Calvin Rose 813e3fdcfd Merge branch 'windows-ev' into ev 2020-10-11 09:32:17 -05:00
Calvin Rose cb4903fa86 Overhaul of poll loop, redo ev/select. 2020-10-11 09:14:14 -05:00
Calvin Rose 964a800d51 More work on windows event loop code. 2020-10-06 19:07:29 -05:00
Calvin Rose 2e944931b3 Update timestamp function to work on windows. 2020-10-04 15:18:31 -05:00
Calvin Rose db67538311 Work on getting ev support on windows. 2020-10-04 12:46:15 -05:00
Calvin Rose 191d0001f4 Add header on BSDs. 2020-09-07 15:22:18 -05:00
Calvin Rose 1a04ce33f1 Conditionally include epoll headers. 2020-09-07 13:13:28 -05:00
Calvin Rose babfe50550 Merge branch 'master' into ev 
Also add poll implementation for ev.
 2020-09-07 12:52:50 -05:00
Calvin Rose 86e00e865e Merge branch 'master' into ev 2020-08-23 11:25:04 -05:00
Calvin Rose 30522bbf7d Merge branch 'master' into ev 2020-08-16 17:52:36 -05:00
Calvin Rose fb26c9b2c4 Add ev/select and ev/rselect initial implementation. 
Getting closer to a CSP implmententation. Probably
useful to move scheduling fields outside of fibers
and into an external table.
 2020-08-09 00:20:27 -05:00
Calvin Rose 78ffb63429 Disallow mutlitple state machines waiting for a single fiber. 
A 'select' operator will be channel based, not state machine based.
 2020-08-08 07:51:46 -05:00
Calvin Rose cb898fabf4 Set default channel size to 0. 2020-08-03 07:57:02 -05:00
Calvin Rose 742c5bb639 Use a common queue implementation. 
Queues occur in three places, so we use a single
implementation rather than three separate ones. This also
has the result that janet_vm_spawn will not overflow in the case
of channel-heavy, IO-light operation.
 2020-08-01 14:20:58 -05:00
Calvin Rose 297de01d95 Add preliminary channel implementation. 2020-08-01 13:13:58 -05:00
Calvin Rose 2eb2dddb59 Begin work on channels. 2020-07-26 23:45:25 -05:00
Calvin Rose 553b4d9428 Add timeouts to net functions. 
Further debugging of the general timeout system, as well
as having a single fiber wait on multiple state machines (select).
 2020-07-19 19:41:12 -05:00
Calvin Rose cd197e8be3 Add ev/call. 
This is a common operation, and making fibers manually can be tedious.
 2020-07-06 19:13:32 -05:00
Calvin Rose 9ba94d2c6b More work on timeouts and racing listeners. 
When two listeners are racing to resume the same fiber, the
first should cancel out the other.
