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.

drop forward declaration of struct client it's been since the switch to libevent that is no longer needed.

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 :)

added missing prototype

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

added ``alias'' option to define hostname aliases for a server

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

sort the auto index alphabetically

define TLS_VERSION, TLS_CIPHER and TLS_CIPHER_STRENGTH for 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.

fix mkdirs: create directories recursively

handle CGI scripts that replies with the maximum header length allowed the 1024 bytes limits is for the META only, not for the whole response. That means that the maximum size for the header line is 1029!

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.
