During the +* development of the HTTP/FTP/SMTP support, it became aparent that +* error checking was taking a substantial amount of the coding. These +* function greatly simplify the task of checking errors. +* +* The main idea is that functions should return nil as their first return +* values when they find an error, and return an error message (or value) +* following nil. In case of success, as long as the first value is not nil, +* the other values don't matter. +* +* The idea is to nest function calls with the "try" function. This function +* checks the first value, and, if it's falsy, wraps the second value in a +* table with metatable and calls "error" on it. Otherwise, it returns all +* values it received. Basically, it works like the Lua "assert" function, +* but it creates errors targeted specifically at "protect". +* +* The "newtry" function is a factory for "try" functions that call a +* finalizer in protected mode before calling "error". +* +* The "protect" function returns a new function that behaves exactly like +* the function it receives, but the new function catches exceptions thrown +* by "try" functions and returns nil followed by the error message instead. +* +* With these three functions, it's easy to write functions that throw +* exceptions on error, but that don't interrupt the user script. +\*=========================================================================*/ + +#include "luasocket.h" + +#ifndef _WIN32 +#pragma GCC visibility push(hidden) +#endif + +int except_open(lua_State *L); + +#ifndef _WIN32 +#pragma GCC visibility pop +#endif + +#endif diff --git a/ThirdParty/luasocket/src/ftp.lua b/ThirdParty/luasocket/src/ftp.lua new file mode 100644 index 0000000..bd528ca --- /dev/null +++ b/ThirdParty/luasocket/src/ftp.lua @@ -0,0 +1,329 @@ +----------------------------------------------------------------------------- +-- FTP support for the Lua language +-- LuaSocket toolkit. +-- Author: Diego Nehab +----------------------------------------------------------------------------- + +----------------------------------------------------------------------------- +-- Declare module and import dependencies +----------------------------------------------------------------------------- +local base = _G +local table = require("table") +local string = require("string") +local math = require("math") +local socket = require("socket") +local url = require("socket.url") +local tp = require("socket.tp") +local ltn12 = require("ltn12") +socket.ftp = {} +local _M = socket.ftp +----------------------------------------------------------------------------- +-- Program constants +----------------------------------------------------------------------------- +-- timeout in seconds before the program gives up on a connection +_M.TIMEOUT = 60 +-- default port for ftp service +local PORT = 21 +-- this is the default anonymous password. used when no password is +-- provided in url. should be changed to your e-mail. +_M.USER = "ftp" +_M.PASSWORD = "anonymous@anonymous.org" + +----------------------------------------------------------------------------- +-- Low level FTP API +----------------------------------------------------------------------------- +local metat = { __index = {} } + +function _M.open(server, port, create) + local tp = socket.try(tp.connect(server, port or PORT, _M.TIMEOUT, create)) + local f = base.setmetatable({ tp = tp }, metat) + -- make sure everything gets closed in an exception + f.try = socket.newtry(function() f:close() end) + return f +end + +function metat.__index:portconnect() + self.try(self.server:settimeout(_M.TIMEOUT)) + self.data = self.try(self.server:accept()) + self.try(self.data:settimeout(_M.TIMEOUT)) +end + +function metat.__index:pasvconnect() + self.data = self.try(socket.tcp()) + self.try(self.data:settimeout(_M.TIMEOUT)) + self.try(self.data:connect(self.pasvt.address, self.pasvt.port)) +end + +function metat.__index:login(user, password) + self.try(self.tp:command("user", user or _M.USER)) + local code, reply = self.try(self.tp:check{"2..", 331}) + if code == 331 then + self.try(self.tp:command("pass", password or _M.PASSWORD)) + self.try(self.tp:check("2..")) + end + return 1 +end + +function metat.__index:pasv() + self.try(self.tp:command("pasv")) + local code, reply = self.try(self.tp:check("2..")) + local pattern = "(%d+)%D(%d+)%D(%d+)%D(%d+)%D(%d+)%D(%d+)" + local a, b, c, d, p1, p2 = socket.skip(2, string.find(reply, pattern)) + self.try(a and b and c and d and p1 and p2, reply) + self.pasvt = { + address = string.format("%d.%d.%d.%d", a, b, c, d), + port = p1*256 + p2 + } + if self.server then + self.server:close() + self.server = nil + end + return self.pasvt.address, self.pasvt.port +end + +function metat.__index:epsv() + self.try(self.tp:command("epsv")) + local code, reply = self.try(self.tp:check("229")) + local pattern = "%((.)(.-)%1(.-)%1(.-)%1%)" + local d, prt, address, port = string.match(reply, pattern) + self.try(port, "invalid epsv response") + self.pasvt = { + address = self.tp:getpeername(), + port = port + } + if self.server then + self.server:close() + self.server = nil + end + return self.pasvt.address, self.pasvt.port +end + + +function metat.__index:port(address, port) + self.pasvt = nil + if not address then + address, port = self.try(self.tp:getsockname()) + self.server = self.try(socket.bind(address, 0)) + address, port = self.try(self.server:getsockname()) + self.try(self.server:settimeout(_M.TIMEOUT)) + end + local pl = math.mod(port, 256) + local ph = (port -
