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.
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 (github/master, origin/master)
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 :)
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" (tags/v1.6)
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.
handle SIGHUP gracefully
i.e. don't print scary messages with LOG_CRIT priority!
