luasocket/TODO

ajeitar os README.*
ajeitar select. upvalue nao tem nada a ver...
make sure filter.chain fails gracefully.
ajeitar o manual sobre select, mais liberal agora

falar sobre encodet/wrapt/decodet no manual sobre mime

RECEIVE MUDOU!!! (partial stuff) COLOCAR NO MANUAL.
HTTP.lua mudou bastante também.
pump.step usado em todo mundo que recebe source ou sink

sources ans sinks are always simple in http and ftp and smtp
expose encode/decode tables to provide extensibility for mime module
use coroutines instead of fancy filters

check garbage collection in test*.lua
pop3???


add socket.TIMEOUT to be default timeout? 

manual
    compatibility: select sets are associative
    add socket.connect and socket.bind to the manual
    say what a nil callback does for http
    check all occurences of it's
    - add shutdown
    - add gethostname
    the need of a content-length header in the post method...
    notice the change in callback conventions
    the callback.lua module and the new mime module.
    escape and unescape in url, not in code!
    add timeout and proxy to request table
    change stay to redirect 
    socket.time and socket.sleep
    - connect with timeout
    local connect 
    add thanks to 'carlos cassino' and 'david burgess'
    add new ip- options and reuseaddr option
    - add listen to manual
    bind method doesn't do listen anymore
    bind doesn't turn an object into a server object: listen does.

tests
    checar todos os metodos
    checar todas as globais
    checar garbage collection
    check for interrupts

wrp can't break lines in the middle of a line break.

add comments into each C module.
testar os options!

use gethostname it in SMTP

make sure modules know if their dependencies are there.

250 HELP

Change return of send and receive callbacks to allow for 
new functions. "" signals end of transmission. Pass total 
number of bytes in request table for HTTP. Callback has nothing
to do with it.

Make sure nobody can fuck up with the metatables...



Adjust dates in all files

Test the library on every system possible

Add service name translation.
Ajeitar o protocolo da luaopen_socket()... sei lá qual é.


- adicionar exemplos de expansão: pipe, local, named pipe


- Fazer compilar com g++
- Thread-safe
  - proteger get*by*.* com um mutex GLOBAL!
  - proteger ou atomizar o conjunto (timedout, receive), (timedout, send)
  - inet_ntoa também é uma merda.
- SSL

- unix 92 bytes maximo no endereço, incluindo o zero
- unix 9216 maximo de datagram size

--------------
these are done
--------------

* should be interrupt-safe
* notice the change in callback conventions
* new mime module replacing old code module (faster, more functionality)
* new socket options (many)
* only allocate in case of success
* optimize for success (only call select if fails) 
* add proxy support to http
* add gethostname 
* local connect 
* connect with timeout
* change code to mime
* change stay to redirect 
* add shutdown
* change send/recv to avoid using select
* O location do "redirect" pode ser relativo ao servidor atual (não pode,
  mas os servidores fazem merda...)
* Ajeitar para Lua 5.0
* Padronizar os retornos de funccao
* Separar as classes em arquivos
* Retorno de sendto em datagram sockets pode ser refused
* select sets are now associative
* colocar pump.all, pump.step
* mudar ltn12.html e usar o exemplo source.cat que está muito melhor.
* break smtp.send into c = smtp.open, c:send() c:close()
* fazer com que a socket.source e socket.sink sejam "selectable".
* change mime.eol to output marker on detection of first candidate, instead
  of on the second. that way it works in one pass for strings that end with 
  one candidate.
* unify backbone of smtp and ftp
* unify filter and send/receive callback. new sink/source/pump idea.
* get rid of aux_optlstring
* get rid of unpack in mime.lua
* create socket.(sink|source).simplify 
* break chain into a simpler binary chain and a complex (recursive) one. 
* Create a passive mode option for the FTP (good for firewall).
* Modules should return their namespace table in the end of the chunk.
* get.lua precisa de ftp.get com url e sink
* conjunto associativo
* colocar um userdata com gc metamethod pra chamar sock_close (WSAClose);
* call select before accept, not after, dumbass!
* get rid of setnonblocking/setblocking in the bind function
* close has to block...
* fmt is not a good name
* change wrap() to accept a number and default to "character"
* move gethostname to dns table
* get rid of _cb in name of functions? 
* trust character constants in mime.c? yup.
* smtp.lua needs stuff filter
* new option.c module to put all options (TCP and UDP share...)?
* add _tostring methods!
* change all modules to use the new namespace scheme
* write some utilities that use the code.lua module and put them 
* in etc, modify the README.etc file and makefile.dist (eol.lua is done)
