Omar Polo de428fff65 normalize schema when parsing the IRI 
RFC3986 in section 3.1 "Scheme" says that

> Although schemes are case-insensitive, the canonical form is
> lowercase and documents that specify schemes must do so with
> lowercase letters.  An implementation should accept uppercase
> letters as equivalent to lowercase in scheme names (e.g., allow
> "HTTP" as well as "http") for the sake of robustness but should only
> produce lowercase scheme names for consistency.

so we cope with that.  The other possibility would have been to use
strcasecmp instead of strcmp when checking on the protocol, but since
the "case" version, although popular, is not part of any standard
AFAIK I prefer downcasing while parsing and be done with it.

Omar Polo 9862b637c2 track handshakes 
This alter the current state machine by adding S_HANDSHAKE as the
initial state.  There, we ensure we did the handshake and we check
SNI.  ATM we simply continue in S_OPEN, but later we can add virtual
host checks there, and skip to S_INITIALIZING with an error state if
the client is accessing a wrong host.

Omar Polo 80bbcad5f2 make FATAL and LOG inline functions 
other functions that aren't macros anymore.  LOG went under a rename
to logs because log is a builtin (the math function), or so gcc says.

Omar Polo 9b374f41ee macro reordering 
and while there replace SAFE_SETENV with an inline function.  LOG is
more difficult to transform into an inline function, given the string
concatenations it does.  The other LOG* and FATAL macros are fine as
they already are.

Omar Polo 579e21b35a switch some macros to inline functions 
they expanded multiple times their argument, since inline is standard
(and works on GCC 4 too!) why don't use it?

Omar Polo ef04b55160 switch to Bjoern Hoehrmann UTF-8 decoder 
It's correct, while my hacked valid_multibyte_utf8 would allow things
that aren't technically UTF8.

ignore also SIGHUP 
SIGHUP is sent when the tty is detached and by default kills the
process.  When we run in the background we don't care anymore about
the tty, so it should be safe for us to ignore SIGHUP.  (frankly,
I expected daemon(3) to do stuff like this for us).

IRI support 
This extends the URI parser so it supports full IRI (Internationalized
Resource Identifiers, RFC3987).  Some areas of it can/may be improved,
but here's a start.

Note: we assume UTF-8 encoded IRI.

mention the %2F caveat 2020-12-25 13:15:15 +01:00
Omar Polo 33d32d1fd6
implement a valid RFC3986 (URI) parser 
Up until now I used a "poor man" approach: the uri parser is barely a
parser, it tries to extract the path from the request, with some minor
checking, and that's all.  This obviously is not RFC3986-compliant.

The new RFC3986 (URI) parser should be fully compliant.  It may accept
some invalid URI, but shouldn't reject or mis-parse valid URI.  (in
particular, the rule for the path is way more relaxed in this parser
than it is in the RFC text).

A difference with RFC3986 is that we don't even try to parse the
(optional) userinfo part of a URI: following the Gemini spec we treat
it as an error.

A further caveats is that %2F in the path part of the URI is
indistinguishable from a literal '/': this is NOT conforming, but due
to the scope and use of gmid, I don't see how treat a %2F sequence in
the path (reject the URI?).

"concurrently" means at the same time, which can be confusing when we
say that it's single-threaded on a single process.

make -d handle correctly non-absolute paths 
before the -d option only accepted absolute paths, and this wasn't
documented.  Even more, with the default value of "docs" it won't
work.  Now it transforms all relative paths to absolute paths before
going on.

[cgi] added support for path parameters 
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.
