We can close directly in event_step without bad side effects,
and then we also don't need to take a reason arg from worker_quit,
since we weren't logging it anywhere.
|
|
The master process only dies once and we close ourselves right
away. So it doesn't matter if it's level-triggered or
edge-triggered, actually, but one-shot is most consistent with
our use and keeps the kernel from doing extra work.

We can avoid the EPOLL_CTL_ADD && EPOLL_CTL_MOD sequence with
a single EPOLL_CTL_ADD.
|

Having separate read/write callbacks in every class is too
confusing to my easily-confused mind. Instead, give every class
an "event_step" callback which is easier to wrap my head around.
This will make future code to support IO::Socket::SSL-wrapped
sockets easier-to-digest, since SSL_write() can require waiting
on POLLIN events, and SSL_read() can require waiting on POLLOUT
events.

These modules are unmaintained upstream at the moment, but I'll
be able to help with the intended maintainer once/if CPAN
ownership is transferred. OTOH, we've been waiting for that
transfer for several years, now...
Changes I intend to make:
* EPOLLEXCLUSIVE for Linux
* remove unused fields wasting memory
* kqueue bugfixes e.g. https://rt.cpan.org/Ticket/Display.html?id=116615
* accept4 support
And some lower priority experiments:
* switch to EV_ONESHOT / EPOLLONESHOT (incompatible changes)
* nginx-style buffering to tmpfile instead of string array
* sendfile off tmpfile buffers
* io_uring maybe?

Using update-copyrights from gnulib
While we're at it, use the SPDX identifier for AGPL-3.0+ to
ease mechanical processing.

git clones may take longer than 30s, much longer... So prepare
to wait almost indefinitely for sockets to timeout and document
the second signal behavior for immediate shutdown.
While we're at it, move parent death handling to a separate
class to avoid Danga::Socket->AddOtherFds, since that does not
allow proper handling the parent pipe being closed and would
actually misterminate a worker prematurely. t/nntpd.t is update
to illustrate the failure with workers enabled.
We will work to keep memory usage low and let clients take their
time without interrupting them.
