d3147b661b Add :pipe to os/spawn for piping to subprocess. 
Similar to Python's subprocess.PIPE, this creates and manages pipes
automatically for the caller.

24b8b0e382 Fix NaNboxing bug that cause flaky builds. 
The macro janet_checktype(x, JANET_NUMBER) was incorrect when
x was NaN. This caused the initial unmarshalling dictionary to be missing
entries in certain cases.

e7fca0051e Add :a option to os/execute, and allow redirecting stdio. 
This should help cover a number of common cases for
use of subprocesses. This should also eventually work well
with the ev branch via

28439d822a Add cancel function. 
This should allow better stack unwinding on a fiber that
no longer needs to complete.

Calvin Rose
5377e10532 Address #466? 
Do not restore pc when returning from top most fiber frame.

Also add JANET_DEBUG config define for various debugging related
configurations. In fiber.c, when debug is enabled we reallocate the
entire stack everytime we push a frame to help uncover use after free
errors.

Calvin Rose
ca75f8dc20 Address #463 - prevent sigpipe on client connections. 
We erroneously did not set SO_NOSIGPIPE on connections aquired with
net/connect, only those quired thorugh net/server. This meant that
failed writes by a client could send sigpipe.

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

78ffb63429 Disallow mutlitple state machines waiting for a single fiber.

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

b731f6ab03 Fix build on NetBSD. 
The NetBSD C library's headers do not expose extensions when
compiling with -std=c99 (as opposed to -std=gnu99 or no -std=
option), so define _NETBSD_SOURCE to get timegm, and functions
that would otherwise require an _XOPEN_SOURCE definition, e.g.
realpath.

Note that, as with FreeBSD, you need gmake to compile janet
on NetBSD, and can also install it from packages.

ba08e487cb Disable PRF by default. 
Since it is not any better by default without initializing the key, we
disable it by default. It can be turned on with JANET_PRF in
janetconf.h.

as having a single fiber wait on multiple state machines (select).

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.

- Allow sending stderr, stdout, and stdin over thread.

dc259b9f8e Set fiber env for heavyweight threads. 
Since you already incur the cost of creating the
core environment, this is probably what you want anyways.
This will make eval and other reflective code work as expected.

b89f0fac7b Move clock shims to util (Helps #430).

db63d352a2 Add specialization for 3 argument get. 
This can be inlined with jmpnn instruction (jump if not nil) to
skip over the default value.

(get a b c)

can be exanded statically to

asm start:
    (get $0 $1 $2)
    (jmpnn $0 :label)

de9951594e Allow setting dynamic bindings at C top level. 
Before, these bindings we just ignored. However, it useful for
controlling janet_printf and janet_eprintf, for example. These can
be called from C code without being inside a call to janet_continue.

561fc15ae9 Address #426 parse errors in *out janet_dostring

803f17aa90 Add eachy and repeat to make looping easier. 
Like eachk and eachp, use eachy and repeat to bring loop
verbs outside of the loop macro. These new macros are very simple
and easy to understand, in contrast to the loop macro which is of
medium complexity.

6d096551f0 Add Peg combinators 'to' and 'thru'. 
Inpsired by the REBOL operators of the same name, these
combinators match bytes up to or inculding a given pattern.
(to patt) is (almost) equalivalent to (any (if-not patt 1)), and
(thru patt) is equivalent to (* (to patt) patt). The one difference
is that if the end of the input is reached and patt is not
matched, the entire pattern does not match.

123710078d Add unix domain socket support to net. 
Code is a bit messy, as getaddrinfo does not support
unix domain sockets directly. We require a keyword :unix
instead of the usual hostname string, and the port is the
path to unix domain socket. The UDS should support both stream
and datagram sockets.

We needed to verify the FuncEnvs actually pointed to a stack frame if
they were of the "on-stack" variant. There was some minor checking
before, but it was not enough to prevent func envs from pointing to
memory that was off of the fiber stack, overlapping stack frames, etc.
