This change gives applications full control to deny clients
from uploading unwanted message bodies. This also paves the
way for doing things like upload progress notification within
applications in a Rack::Lint-compatible manner.
Since we don't support HTTP keepalive, so we have more freedom
here by being able to close TCP connections and deny clients the
ability to write to us (and thus wasting our bandwidth).
While I could've left this feature off by default indefinitely
for maximum backwards compatibility (for arguably broken
applications), Unicorn is not and has never been about
supporting the lowest common denominator.

The default is false because some applications were not
written to handle partial reads (even though IO#read allows
it, not just IO#readpartial).
|
|
The following specifications to bind port 8080 on all interfaces
are now accepted in the configuration file:
listen "8080" # (with quotes)
listen 8080 # (without quotes)
|
|
Run tests with warnings so we detect stupid things like this.
|
|
Premade lambda/proc/Proc objects may all be passed, to the
hooks, not just anonymous blocks.
|
|
* Expand addresses like "1:8080" to "127.0.0.1:8080"
beforehand so sock_name() in SocketHelper will
always return consistent results.
* Add support for "unix:/path/to/foo" paths for easier
synchronization with nginx config files.

Instead of having global options for all listeners,
make all socket options per-listener. This allows
reverse-proxies to pick different listeners to get
different options on different sockets.
Given a cluster of machines (10.0.0.1, 10.0.0.2, 10.0.0.3)
running Unicorn with the following config:
------------------ 8< ----------------
listen "/tmp/local.sock", :backlog => 1
listen "*:8080" # use the backlog=1024 default
------------------ 8< ----------------
It is possible to configure a reverse proxy to try to use
"/tmp/local.sock" first and then fall back to using the
TCP listener on port 8080 in a failover configuration.
Thus the nginx upstream configuration on 10.0.0.1 to
compliment this would be:
------------------ 8< ----------------
upstream unicorn_cluster {
# reject connections ASAP if we are overloaded
server unix:/tmp/local.sock;
# fall back to other machines in the cluster via "backup"
# listeners which have a large backlog queue.
server 10.0.0.2:8080 backup;
server 10.0.0.3:8080 backup;
}
------------------ 8< ----------------
This removes the global "backlog" config option which
was inflexible with multiple machines in a cluster
and exposes the ability to change SO_SNDBUF/SO_RCVBUF
via setsockopt(2) for the first time.

Use of #process_based_port as port number.
Exclude DirHandler(nil) with absolute paths on Windows.

They are mainly unit tests anyway; we can clean them up more moving forward.
