[cgi] switch from pipe(2) to socketpair(2) We can't use normal pipe(2)s with libevent in some cases. Switch to socketpair(2), which doesn't have the same problem. This has the drawback that it doesn't prevent the CGI script from reading stdout, for instance. (sockets are two-way, pipes only one-way)

PF_UNIX is not a valid protocol for socketpair OpenBSD accept it, but FreeBSD disallows it. PF_UNSPEC (or 0) should be used instead. The FastCGI bit in the regress suite still doesn't work on FreeBSD, but at least now it starts.

don't leak a file descriptor make sure we always close every fd in every possible code path; while there, also add a log_err if fork(2) failed.

don't let CGI scripts inherit our stderr our stderr could have been sent to the logger process, so it may be invalid. Furthermore, in the future we may want to capture also the stderr of the processes.

define and use GMID_VERSION

use the correct document root pass the correct loc_off to the executor, so the various variables that depends on the matched location (like DOCUMENT_ROOT) are computed correctly.

fastcgi: a first implementation Not production-ready yet, but it's a start. This adds a third ``backend'' for gmid: until now there it served local files or CGI scripts, now FastCGI applications too. FastCGI is meant to be an improvement over CGI: instead of exec'ing a script for every request, it allows to open a single connection to an ``application'' and send the requests/receive the responses over that socket using a simple binary protocol. At the moment gmid supports three different methods of opening a fastcgi connection: - local unix sockets, with: fastcgi "/path/to/sock" - network sockets, with: fastcgi tcp "host" [port] port defaults to 9000 and can be either a string or a number - subprocess, with: fastcgi spawn "/path/to/program" the fastcgi protocol is done over the executed program stdin of these, the last is only for testing and may be removed in the future. P.S.: the fastcgi rule is per-location of course :)

allow ``root'' rule to be specified per-location block

added ``env'' option to define environment vars for CGI scripts

restore signal handlers before exec'ing CGI scripts


list instead of fixed-size array for vhosts and locations saves some bytes of memory and removes the limit on the maximum number of vhosts and location blocks.

gmid v1.6 -- "Stargazers"

move all sandbox-related code to sandbox.c while there, add capsicum for the logger process

refactoring: imsg everywhere use imsg to handle ALL kinds of IPC in gmid. This simplifies and shorten the code, and makes everything more uniform too.
