enhance the CGI scripting support so that script can take path
parameters. That is, a script at /cgi/foo is called when the request
path is /cgi/foo/bar/...
This commit also introduce some backward incompatible changes as the
default env variables set for the CGI script changed.
This is a first try at implementing CGI scripting. The idea is that,
if CGI is explicitly enabled by the user, when a user requires an
executable file instead of serving it to the client, that file will be
executed and its output fed to the client.
There are various pieces that are still lacking, the firsts that comes
to mind are:
- performance: the handle_cgi just loops ignoring the
WANT_POLLIN/POLLOUT and blocking if the child process hasn’t
outputted anything.
- we don’t parse query variable (yet)
- we need to set more variables in the child environment
side question: it’s better to set the variables using setenv() or
by providing an explicit environment?
- document what environment the CGI script will get
- improve the horrible unveil/pledge(cgi ? …)
but now I can serve “hello-world”-tier script from gmid!
