The `janet_get_addrinfo` function retained code that was meant for
compliance with 3 separate function signatures under a single function
name. Changing things to be a single function signature was broken until
the code pertaining to the aforementioned was stripped out.
Prior commits was an attempt to make this one function adhere to 3
different function signatures! This puts an end to that and makes it
where it's a single function signature and if one wants to use the 4th
argument they'll need to explicitly set the 3rd argument (to nil for
default).
janet_get_sockettype expects a keyword but we're making it optional that
the call to the functions that use it with arity >=3 will be guaranteed
to have it as a keyword value! If it's not a keyword then it's the same
as NULL.
Primarily because trying to check the value results in a panic when the
value is not the type of value requested from the API. Also probably
cheaper and the previous idea of just getting the value then comparing
was pretty stupid (needed a string comparison... and was going to do
pointer comparison).
This will allow us to set the address we use for outgoing connections.
Builds, haven't checked it passes current tests, haven't checked it
actually works either.
Minimum interval for a timer must be 1 or more (or we get EINVAL) and
Janet fails tests and halts events that the programmer may still be
interested in.
A comptime known value of 0 for data in EV_SET with EVFILT_TIMER causes
a complete compilation failure (fails to link). This fixes it by making
it a 1 instead of a 0 for amount of milliseconds in the interval to wait
under NetBSD.
NetBSD and OpenBSD lack NOTE_ABSTIME and NOTE_MSECONDS, so we define
those and create a macro that we use for all timeout values in EV_TIMER
events that will on all BSD excepting FreeBSD change an absolute time
into an interval.
Checking throught NetBSD's man pages, excepting for NetBSD-current,
NetBSD uses `intptr_t` as the type for `.udata`. This change allows for
`.udata` to match whatever type (by cast) the underlying system uses.
Pretty obvious I thought control statements were glued to their opening
parenthesis at first and then I realized not and voila, a bundle of
mixed style. Hopefully this fixes all of it.
From this point things should be bug fixes or code formatting most
likely.
Updated commentary (removed superfluous comments, and commented out
code). Refined commentary where it seemed important and may help whoever
comes behind me keep from making bad assumptions similar to the ones I
made.
All tests ran with `gmake test` now pass. `valgrind` with FreeBSD does
not support forking so `gmake valtest` fails once child processes are
started. Determined not an issue, can't fix valgrind.
Need to guard against errors when reading/writing probably, if there is
an error, forgo those events.
Guard against null state (and the byproduct, a segfault), check if the
state is null before utilizing it.
Note that this is a work in progress and simply a first attempt at
getting some code into place before being able to test it. This code
follows of sorts both the poll and epoll sections of the codebase hoping
to achieve the exact same.
Relax check that number of closure environments in a function matches
that of the def.
The def could be partially constructed, and so there may be a false
negative. The runtime will check that this is consistent, and the
garbage collector should handle when this constraint is not kept.
A threaded abstract is an abstract type that can be freely shared
between threads. While no synchronization is provided, refcounting
and transport between threads is. This will let implementers more easily
exploit OS-level parallelism in C library code. The caveat with these
types is that they need to be careful in how they interact with objects
on other heaps.
Some pointer casting with abstract types was incorrect, resulting
in strange behavior when trying to use supervisor channels that were
threaded. This fix also adds the ability to supply a supervisor channel
directly when creating a thread.
Introduces close semtantics to channels as well, but otherwise
threaded channels behave much like non-threaded channels. They have
different marshalling behavior though, and can only send values over by
packing and unpacking them. For now, this means only primitive values
although this will be expanded.
Also missing some implementation for closing threaded channels, and a
whole lot of testing. Achtung!, Caveat emptor, here be dragons and bugs.
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.
