In the same spite of the last commit, add the missing separators
between strings to avoid the auto-concat pitfalls. `=>' is used to
separate between `env' and `param' arguments, while for `fastcgi' the
keyword `port' is required between the hostname/ip address and the
port (if provided).
Since `env', `param' and `fastcgi' are all new stuff, there's no need
to keep compatibility.
With the newish automatic string concatenation, options like `mime'
that accepts two strings as parameter start to become ambiguous: which
strings gets concatenated? Instead of trying to document in the
manpage which argument(s) is subject to string concatenation, do the
concat always and introduce a separator. In the case of mime,
`to-ext' now acts as a separator to distinguish. While there, also
use a new keyword because it sounds better.
It's dead-easy to upgrade to the new configuration, possibly with some
sed magic, but for the moment the old `mime' form is preserved: (with
a warning!) Will be dropped in the next release.
Now that we have this auto concat string thingy, macros can simply
expand to standalone strings in place, as single words.
Forgot to point it out in previous commits, but now we can
cert = "/etc/keys"
server "foo" {
cert $cert "/foo.crt"
...
}
this fixes a bug introduced with the prefork mechanics: every server
process shared the same socket, and this would cause a race condition
when multiple server processes asked for a script cgi being executed.
This gives each server process its own socket to talk to the executor,
so the race cannot happen.
