reported by Monk (#0003453). It should be large enough now. Also changed the
way we deal with this when it happens (if it ever happens again..): we now
close the server connection, instead of trying to continue, because continueing
is too dangerous.
* same for scan message
* don't say "you have not registered" on NOTICE in unregistered state.
* made a send_prot(aClient, ConfigItem_link) for sending PROTOCTL message,
takes care of sending ZIP in token in case of a ziplink (indeed, I don't
send "ZIP" if it's not marked as a ziplink).
* added automatic fallback tot uncompressed link in case one of the sides
has zip turned off or not compiled in.
* added configcheck for link::options::zip turned on when not compiled
in (just like we do with ssl).
- Currently it's not possible to compile with ZIP_LINKS _and_ SSL without changing zlib.h :(.
It really sucks... it's because zlib.h has a typedef for 'free_func' and this is also used
in openssl header files as a (useless) name... :((. I did some updates to allow future zlib
changes, dunnow if they will because it can break other zlib programs. It compiled fine at
windows, but not at Linux... you need to replace free_func to zlib_free_func in zlib.h in
order to get ZIP_LINKS + SSL to work... but like I said, that may break programs (ARGH!).
instead of using a 2nd flag here for the special case of "the first zip msg"
like in hybrid/etc I use cptr->zip->first to flag that. Except for the many
#ifdef ZIP_LINKS blocks added I also had to do some stuff outside it, like
crc32->our_crc32 because zlib defines it, made a READBUF define (8192),
added a msg var to parsing/send functions.. blah.. etc ;P.
I've also put the patch online at www.vulnscan.org/tmp/zip_links.diff so you
can easily look what I've changed.
TODO: ask in ./Config if ziplinks should be enabled and let ./configure check
for zlib + add the library to IRCDLIBS in Makefile if enabled.
TODO: some little code cleanups
