This is done by passing AI_ADDRCONFIG to getaddrinfo().
On Linux, setting net.ipv6.conf.all.disable_ipv6 to 1 will now be
respected.
On FreeBSD, AI_ADDRCONFIG filtering is currently implemented by
attempting to create a datagram socket for the corresponding family,
which succeeds even if the system doesn't in fact have any addresses
of that family configured. That is, if the system with IPv6 support
in the kernel doesn't have IPv6 addresses configured, AI_ADDRCONFIG
will filter out IPv6 only inside a jail without IPv6 addresses or
with IPv6 disabled.
The $NGX_AUTO_CONFIG_H added to perl module Makefile dependencies to
make sure it's always rebuild after a configure. It is needed as we
expand various variables used for Makefile generation during configure
(in particular, nginx version).
Dependancy tracking introduced in r5169 were not handled absolute path
names properly. Absolute names might appear in CORE_DEPS if --with-openssl
or --with-pcre configure arguments are used to build OpenSSL/PCRE
libraries.
Additionally, revert part of r5169 to set NGX_INCS from Makefile
variables. Makefile variables have $ngx_include_opt in them, which
might result in wrong include paths being used. As a side effect,
this also restores build with --with-http_perl_module and --without-http
at the same time.
To avoid further breaks it's now done properly, all the dependencies
are now passed to Makefile.PL. While here, fixed include list passed to
Makefile.PL to use Makefile variables rather than a list expanded during
configure.
Filename extension used for dynamically loaded perl modules isn't
necessarily ".so" (e.g., it's ".bundle" on Mac OS X).
This fixes "make" after "make" unnecessarily rebuilding perl module.
Added missing dependencies for perl module's Makefile.
Simplified dependencies for perl module nginx.so: it depends
on Makefile that in turn depends on other perl bits.
Note: the "-p" argument of cp(1) dropped intentionally, to force nginx.so
rebuild. It is considered too boring to properly list all dependencies
in Makefile.PL.
This includes "debug_connection", upstreams, "proxy_pass", etc.
(ticket #92)
To preserve compatibility, "listen" specified with a domain name
selects the first IPv4 address, if available. If not available,
the first IPv6 address will be used (ticket #186).
On Mac OS X system toolchain by default prefers include files
from /usr/local/include, but libraries from /usr/lib. This might result in
various problems, in particular the one outlined below.
If the PCRE library is installed into /usr/local/, this results in pcre.h
being used from /usr/local/include (with PCRE_CONFIG_JIT defined), but
libpcre from /usr/lib (as shipped with the OS, without pcre_free_study()
symbol). As a result build fails as we use pcre_free_study() function
if we try to compile with PCRE JIT support.
Obvious workaround is to the root cause is to ask compiler to prefer
library from /usr/local/lib via ./configure --with-ld-opt="-L/usr/local/lib".
On the other hand, in any case it would be good to check if the function
we are going to use is available, hence the change.

Very basic version without any OCSP responder query code, assuming valid
DER-encoded OCSP response is present in a ssl_stapling_file configured.
Such file might be produced with openssl like this:
openssl ocsp -issuer root.crt -cert domain.crt -respout domain.staple \
-url http://ocsp.example.com
HP-UX needs _HPUX_ALT_XOPEN_SOCKET_API to be defined to be able to
use various POSIX versions of networking functions. Notably sendmsg()
resulted in "sendmsg() failed (9: Bad file number)" alerts without it.
See xopen_networking(7) for more details.
This fixes alignment problems observerd on ARMs, and likely also needed
for MIPSes. Unless we know alignment is not required just assume we
need 16, which appears to be safe default for all architectures.
