Christopher Wellons 4cb4fc6eac Use CPPFLAGS in the Makefile (closes #43) 
Debian uses CPPFLAGS to pass arguments like -D_FORTIFY_SOURCE=2.

Christopher Wellons 24bc7639d1 Always set standard output to line-buffered 
When logging was enabled via the config file, standard output was left
fully buffered. Logs should never be fully buffered.

Thanks to Chang-Li for pointing this out.

Christopher Wellons 6f621b90b1 Tweak SIGUSR1 statistics totals logging 
* Don't dynamically allocate the struct since that's not necessary.
* Use a more concise log message.
* Include current clients when counting the time.
* Print final statistics message *after* closing all clients.
* Don't include total connections in ACCEPT.
* Mention SIGUSR1 in the new man page, too.

Adjusts #24.

Christopher Wellons c50585f759 Rename uepoch() to epochms() 
It returns milliseconds, not microseconds.

Christopher Wellons 38e35ad4c9 Add note about __EXTENSIONS__ to README (illumos) 2019-04-04 21:44:44 -04:00
Christopher Wellons 494c68b8d7 Use _XOPEN_SOURCE instead of _POSIX_C_SOURCE 
It seems this is required to get all the IPv6 definitions, though most
systems aren't very picky. NetBSD seems to be one of those picky
systems, though.

Christopher Wellons 9f4bdc123d Greatly simplify a bunch of things 
1. If sockets are non-blocking, no need to use poll() on them. Just try
to write regardless and ignore the outcome. This means we don't need the
pollvec stuff anymore.

2. getline(3) is apparently still too new to POSIX that it's hard to use
portably. We don't really need it that badly anyway.

3. Don't use MSG_DONTWAIT. It's non-standard and apparently still hard
to use portably. Set sockets to non-blocking instead.

4. Since we're not polling on client sockets, the queue is a whole lot
simpler.

Christopher Wellons b1c1599d32 Improve support for Solaris and its derivatives 
Requires extensions to be enabled due to incomplete support for
POSIX.1-2008. However one of the now-exposed extensions is tragically
named "struct queue". This struct was been renamed to "struct fifo".

Thanks to @yvoinov for reporting this issue and collaborating on a
solution.

Closes #14, #17.

Christopher Wellons 7ac1fbff3b Always ignore SIGPIPE 
MSG_DONTWAIT doesn't work quite right on OmniOS / Solaris, so also
disable SIGPIPE.

Christopher Wellons 2bd2b3ca92 Just drop IPV6_V6ONLY (it never works right anyway) 
This doesn't seem to work as documented on any system.
 2019-02-03 15:28:09 -05:00
Christopher Wellons 08a9dfe97e Check for IPV6_V6ONLY before using it 
This is necessary for supporting OmniOS (Solaris), which doesn't
actually document how to actually define this flag. This platform also
requires LDLIBS='-lsocket -lnsl' when compiling.

Christopher Wellons 93b94f6b44 Correct for different definitions of sockaddr_in 
On BSD it doesn't like the braces, and on Linux it prefers braces. Ugh.
