Now main() is much simpler.
Removed all goto.
Less variables in main.
Simplified status_ to status().
Use a stop() function to log, send messages to stderr if necessary and close vger.
Minor fixes with defaults, mimes
There is still work to do to compare path using stat().
looks for files immediately after the cgidir, and anything after that file
if there are '/'s becomes PATH_INFO.
also adds a function strip_trailing_slash which may be useful in other parts too.
a query string could contain a '/' character, which would make vger try
to chdir to an incorrect directory. remove the query_string before this,
and before percent-decoding (in case there is an encoded '?'). This
should happen even if we are not doing cgi, because some clients might
send a query_string anyway, which should be ignored.
Don't fork+execlp the script. There's no need to do so since on exec
the new process will inherit our file descriptor table (and hence our
stdout), so copying from its stdout to ours is just a waste of time.
This allows to drop the ``proc'' pledge(2) promise and to (slightly)
improve performance.
* follow style(9) for prototypes
* move first most used extension for more effeciciency when looking for mime
* add opts.h to deal with options
* remove lang=en by default
* add option to set default mimetype
* add option to autoindex if no index.gmi found
* redirect if ending "/" is missing
* send appropriate status code if request too long
* edit manpage and README for new options
According to the book of armaments(posix):
BUFSIZ
Size of <stdio.h> buffers. This shall expand to a positive value.
There is also no need for the buflen variable since the size never
changes during runtime and the compiler can infer the size via
sizeof().
We are not modifying it so there is no need to copy memory around.
This also prevents file_mime getting out of sync as had already
happend. It had a size of 50 while the mime types database type used
to have a size of 70.
