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.
