Omar Polo 9b8f5ed2c0 revert commit 346f28eeaa 
keep mark_nonblock in utils.c, as otherwise the build for the regress
suite will fail (mark_nonblock needs fatal which is in gmid.c, and
we can't link gmid.o with the regress suite...)

Omar Polo 346f28eeaa move mark_nonblock to utils.c 2021-02-02 23:03:33 +00:00
Omar Polo fe40638928 mark various functions as static 
By marking all those function as static, the compiler is free to do
more optimizations.  In addition, those functions are not used outside
server.c

Omar Polo 35744950aa simplify handle_cgi 
Now that I got rid of the enum+switch, adding more state is easier.
Before, we used an hack to remember if we had read the CGI reply or
not (c->code = -1).

This introduces a new state, handle_cgi_reply that reads the CGI
script reply, logs it, and only then switches to handle_cgi.
handle_cgi itself is cleaner, now it only reads into c->sbuf and send
what it had red.

We even get, almost for free, the 42 error.  If read exists with -1 or
0 from in handle_cgi_reply, we return a proper error to the client.
We can extend this further in the future and also try to validate the
CGI reply (for now we're only looking for a \n).

Omar Polo 6016a593a3 invert the location precedence: first match wins 
It's how httpd(8) does it, and it allows us to call fnmatch less time

Omar Polo 35cf19e3f3 punycode: refactoring 
use the correct term "label" instead of "component" when speaking
about the parts of a hostname.  Also, fix the sizes for max hostname
and label.

Omar Polo 07b0a14218 void-ify some functions 
their return value is no longer used, it's only confusing at this point.

Omar Polo a87f662565 refactoring state management 
instead of having a flag to discern between two different behaviours
in S_SENDING, split that state into S_SENDING_FILE and S_SENDING_CGI
(this will also make it easier in the future to add other sending
states).  While there, also get rid of `goodbye' and make start_reply
advance the state machine by itself.

Omar Polo 0be51733ef improve logs 
now we log the full IRI requested (before was only the path) and the
response line (even for CGI).

Omar Polo 2debfe2b1f drop useless field 
was probably added to distinguish between AF_INET and AF_INET6, to use
different functions for logging.  But it wasn't really used, and now
we use getnameinfo anyway.

we still have an hardcoded list, but this implements the API needed to
modify the mappings.
 2021-01-18 18:18:57 +00:00
Omar Polo d3a08f4d17 reorganize: move bunch of functions to server.c 
cgi.c wasn't really needed; it better to group all the server related
functions together, cgi or not.  Now gmid.c contains only startup and
utility code.
