. Added make_sorted_dirlist(), cleanup_sorted_dirlist().

b2b6d75a05 . In NDEBUG, safefree() is just free(). 
. Originally there were three places where a pointer was NULL'd after
  being freed.  One of these is actually important, so annotate it.

e127c6acda make_safe_uri() improvements. 
. Strip out debugging.
. Fix (elements == 0) returning an empty string.
 2013-04-28 19:44:11 +10:00
Emil Mikulic
b082fa213f Faster, simpler, not yet completely correct reimplementation of 
make_safe_uri().  It still has a lot of debugging cruft inside.

Emil Mikulic
b2f504f975 . Add consolidate_slashes(). 
. make_safe_uri() may modify the URI string given to it.

41d2f5867a Solaris compatibility fixes. 
. INADDR_NONE is -1
. Change bindport to an unsigned short (ntohs implies short).
. Conditionally implement our own errx() and err().
. Conditionally use a custom vasprintf() that depends on vsnprintf().

466de20e2e . Cosmetics. 2013-04-28 19:44:11 +10:00
Emil Mikulic
255a78d0c4 . strip_endslash() should not have been reallocating argv[1] 
. Remove strip_endslash() by boiling it down to one line and putting
  that line where the function call used to be.
 2013-04-28 19:44:11 +10:00
Emil Mikulic
f7c0995234 . Don't need to nonblock the listening socket. 
. Use acceptfilter.
 2013-04-28 19:44:11 +10:00

f0766d80f3 . Don't kill the whole server if recv() error occurs. 
. Set conn_close to 1 on error to ensure connection closure.
 2013-04-28 19:44:11 +10:00

376c8b29fb . Make parse_request return int so it can return failure on malformed 
requests.
. Make it bomb out on malformed requests like "moo\r\n\r\n"

00fea650ed . IDLETIME -> idletime 
. Construct keep_alive_field from idletime.
. Send keep_alive_field when there's no `Connection: close'
 2013-04-28 19:44:10 +10:00

dd4a217817 Fix conn->close logic: 
. HTTP/1.1 protocol enables keep-alive.
. `Connection: keep-alive' enables keep-alive, regardless of protocol.
. `Connection: close' disables keep-alive.
 2013-04-28 19:44:10 +10:00
Emil Mikulic
3389cc39d4 . Keep-alive connections work now. 
. free_connection() now calls log_connection() for us.
. keepalive_connection() -> recycle_connection().
. recycle_connection() calls free_connection() (results in logging).
. Don't reset conn->client in recycle.
. Before main select loop, recycle keep-alive DONE connections.
 2013-04-28 19:44:10 +10:00
Emil Mikulic
a07492c1a8 . In poll_send_{header,reply}(), don't bother deallocating stuff that 
free_connection will deallocate anyway.
 2013-04-28 19:44:10 +10:00
Emil Mikulic
2080b05d4c Starting work on Keep-Alive: 
. Added conn_close to struct connection.
  0 = Keep-Alive, 1 = Connection: close
. Added keepalive_connection() for recycling connection structs.
. Made "Connection: close\r\n" in reply headers optional.
. If protocol is HTTP/1.1, use Keep-Alive, unless Connection: close is
  given in the request.

Offtopic:
. Improved request parsing - allow extraneous spaces.

f65f8520a0 . More assertions in split_string(). 
. Make some empty for() loops more obvious.
. Missed a 0 -> '\0' last time.
. err(EXIT_FAILURE, ...) -> err(1, ...) to retain existing style.
. Annotate default_extension_map[] - it must be NULL terminated.
. Don't expand_tilde() -- unsure about this.

 2013-04-28 19:40:21 +10:00
Emil Mikulic
a4740dfda2 . Uncast xmalloc() and xrealloc() returns. 
. Changed `#if IDLETIME' to `if (IDLETIME)' - it will be
  optimized away by the compiler.
. Some casts and an int->size_t change to keep splint happy about
  integer types.
