lighttpd-1.5.0-r1992-native.win32.zip

一直在等lighttpd for win32的发布，终于1.5.0版本中对于Win32的支持已经考虑在内了，但是官方版本是没有推出可以直接在MSVC中编译的工程，因为着急，所以自己改了一个，喜欢研究的朋友可以从这里下载一试！支持Lua!

gcc的语法检查

在编译mod_lua 0.5的过程中，下面的代码出现警告
LuaState *L;
void** data = (void**) &L;
warning: dereferencing type-punned pointer will break strict-aliasing rules

-------------
gcc version 4.1.1 20061011 (Red Hat 4.1.1-30)


somebody say that:

Yes, by implying -fstrict-aliasing, so using -fno-strict-aliasing is a
workaround. The problem is caused by the i386 PCPU_GET/PCPU_SET
implementation:

#define __PCPU_GET(name) ({ \
__pcpu_type(name) __result; \
\
[...]
} else if (sizeof(__result) == 4) { \
u_int __i; \
__asm __volatile("movl %%fs:%1,%0" \
: "=r" (__i) \
: "m" (*(u_int *)(__pcpu_offset(name)))); \
__result = *(__pcpu_type(name) *)&__i; \
[...]

In this case, the PCPU_GET is used to retrieve curthread, causing
sizeof(__result) to be 4, so the cast at the end of the code snippet
is from a u_int * to struct thread *, and __i is accessed through the
casted pointer, which violates the C99 aliasing rules.
An alternative is to type-pun via a union, which is also a bit ugly,
but explicitly allowed by C99. Patch attached (but only superficially
tested).

mod_lua 0.5终于发布了

在mod_lua 0.5上已经花费好大精力了，在经过一番修改与测试之后，在http://mod-lua.sourceforge.net上发布了这个版本，继续其它的工作！ 

几种Apache CGI模块性能简单分析比较 被不带出处转载

今天, 在网上搜索LUA的相关信息，发现自己blog里面的 几种Apache CGI模块性能简单分析比较 在
http://www.mylinux.com.cn/newsTextAction.do?id=15,045 处出现，进去看了一下，居然连转载申明也没有，这样的编辑还真的能搞！

mod_lua性能提升，是mod_python速度115%

在上次的性能对比之后，忍不住对mod_lua的程序作了改进，下面是最新的测试结果

这次修改可谓全胜

每个请求处理花费的时间微妙: 2.156/1.875(mod_python/mod_lua)

性能提升的原因说明:

1 mod_lua从串行处理方式改成并行处理方式
2 lua虚拟机采用了空闲池处理

几种Apache CGI模块性能简单分析比较

最近对  mod_python, mod_php, mod_ruby, mod_lua做一个简单的性能比较，目的是想知道mod_lua在性能方面该如何改进！

工作在Windows 2003, VS 2005下完成，全部采用动态编译
-
mod_python已被捐赈给apache由apache关方维护,轻松搞定(支持python 2.4,不支持python2.5)
mod_php 一直被作为CGI开发的热点,也非常容易搞定
mod_lua 是本人的开源项目,自然不用碰到问题(支持最新lua 5.1.1)
mod_ruby 这个小日本的东西，在他上面花的时间最多, 首先与yarv(ruby 2.0)还不兼容,另外在ruby 1.8.5的编译时候需要在程序内部切换一个宏,另外还有个内存问题! 文档资料也很少.(mod_lua根本还没有文档,我以后会陆续给出)！需要一定的经验,不能自动完成.

( 就我对apache与ruby的了解程度自信可以搞定, 对于小日本开源软件的态度还真不敢恭维,ROR不知是被那位炒起来的, 反正mod_ruby的性能不敢恭维.)

结果比较:

• 模块名称 结果(次/秒)
• mod_python 278.26
• mod_lua 213.33
• mod_php 164.10
• mod_ruby 84.21

mod_python的处理速度果然快, 难怪google实用了很多的python, 不要犹豫, 用python吧！
当然php在WEB开发中的地位已经巩固, 但我相信很快就会被python赶上并超越
我开发的mod_lua,是为嵌入式应用准备的,在执行速度与模块大小方面都不错！且可直接用共享内存来通信 具体大家可以到 http://sf.net/projects/modlua 去了解！
mod_ruby是在是不敢恭维，如果采用eruby估计会更慢，将用ruby开发web的人，需要仔细考虑了

从微尘《一个Python程序的6次改进》想到的

一个Python程序的6次改进 在 http://blog.csdn.net/tinydust 贴出

下面是总结出来的最快的python实现
import datetime

if __name__ == "__main__":
    t1=datetime.datetime.today()
    f = file("email.txt","r")
    f2 = file("email_new.txt","w")
    f2.writelines(set(f))
    f.close()
    f2.close()
    t2=datetime.datetime.today()
    print str(t2-t1)

在我机器上的测试结果:
python 2.5:  0:00:00.172000
这个程序语言特性用到了极致, 近乎完美地解决了问题，佩服！

一位网友的ruby实现
#!/usr/bin/env ruby
t = Time.new

file = 'email.txt'

f1= File.new('email.txt', 'r')
data = f1.readlines
f1.close

f2 = File.new('email_rb.txt', 'w')
f2.write(data.uniq.join)
f2.close
puts Time.new - t

ruby 2.0.0 (Base: Ruby 1.9.0 2006-04-08) [i386-mswin32]
YARVCore 0.4.1 Rev: 545 (2006-09-01) [opts: [inline method cache] ]

这个程序也很酷,结果  0.391

看了之后，马上产生了用lua写一个同样程序的想法！

lines = {}

f1 = io.open ("email.txt","r")
for line in f1:lines() do lines[line] = true end
f1:close()

f2 = io.open ("e_t.txt","w+")
for line in pairs(lines) do f2:write(line, "\n") end
f2:close()
print(os.clock())

Lua 5.1.1 Copyright (C) 1994-2006 Lua.org, PUC-Rio: 0.406
测试结果: Python:Ruby:Lua = 172:391:406

是不是LUA就差了呢！才不是呢！

这也是可以理解的, LUA io操作肯定是没有优化的，没有一次将所有的数据读入/写出，我尝试一次读入出数据，然后对读入的数据按照string的方式来处理，然后一次写盘，测试的结果是比上面的程序慢了一倍，问题在于lua对于字符串的操作同样也为优化，花的时间很长，CPU/内存开销都很大,看来又比要对字符处处理做一个扩展库.
另外将上面的程序两个循环合并成一个同时操作读入/写出文件后性能也不理想，因为同时在两个文件上进行IO操作,硬盘磁头会频繁移动,性能反而降低。LUA的优势要嵌入C/C++才能表现出来！

不过python的表现让我惊奇, rite的表现也很惹人注意。

由于我的开发工作决定使用lua会更好。所以我会继续使用lua.

iolanguage也进入了我的视线，抽空也的研究一下！

LuaCOM for Lua 5.1.1 Fixed!

下面的话是我理解错误造成的！

除了上面引用的 LuaCOM - more questions 中所解决的问题外，LuaCOM 在 Lua 5.1.1中还有一个比较严重的问题，那就是 接口 参数传入有问题，具体原因还不太清楚，可能是lua 5.1与lua 5.0在传入函数参数时，对于堆栈的操作发生改变，类似于下面的代码需要修正！

1 多处定义的 self_param=1,并未在其他地方使用，干脆移除，要不干扰我们对代码的理解！
2 文中多处定义的 const int first_param = 2; 会在COM接口lua 5.1中造成第一个参数丢失，所以改成const int first_param = 1
3 const int num_params = luaCompat_getNumParams(L, 4) - 1; 由于first_param 从2改为1，所以把它改成const int num_params = luaCompat_getNumParams(L, 4);

基本上就这样，还需要更多的验证，另外对luacom的改动，需要内lua的VM机制与COM机制有比较深入的认识，说实话，这两件事情都比较复杂，另外由于luacom的不跨平台性,用ATL与luabind来重新实现应该是比较好的选择，代码量可能会更小！

修改，上面的方法存在问题，如果是用obj.method的方法来调用，需要用上面的方法修改,如果用obj:Method的方法来调用的话，就不需要改拉！

LuaCOM - more questions

	LuaCOM - more questions by Terry Bayne Jan 31, 2006; 09:26pm :: Rate this Message: - Use ratings to moderate (?) Reply | Reply to Author | View Threaded | Link to this Message Good Morning. I've started using LuaCOM and I have a few questions. I am not a COM guru so please excuse my ignorance. I am trying to build on the examples from the LuaCOM documentation, and in doing so I have no problem opening up Microsoft Word. The problem comes when I try to create a new document - most of the examples on the web do something like this: word = luacom.CreateObject("Word.Application") assert(word) word.visible = true -- Works good up to this point doc = word.Documents.Add() The last statement fails. I've tried passing parameters, even tried this: word = luacom.CreateObject("Word.Application") mt = luacom.CreateObject("type.missing") assert(word) word.visible = true -- Works good up to this point doc = word.Documents.Add(mt,mt,mt,mt) All this gets me is a type mismatch error.

	RE: LuaCOM - more questions by Ignacio Burgueño Feb 01, 2006; 05:04am :: Rate this Message: - Use ratings to moderate (?) Reply | Reply to Author | View Threaded | Link to this Message Well. I compiled a debug version of luacom 1.3 (as of 2005-02-28) and it does not work. Indeed, the code fails when calling the Add method from the Word.Document class Its signature is: HRESULT Add( [in, optional] VARIANT* Template, [in, optional] VARIANT* NewTemplate, [in, optional] VARIANT* DocumentType, [in, optional] VARIANT* Visible, [out, retval] Document** prop); I don't know if luacom 1.3 introduced a new approach to handle optional parameters, but I think that the problem lies in the function tLuaCOMTypeHandler::fillDispParams At line 943, there's this code: else if(!byref) // here we filter the optional out params (treated below) { // assumes that a parameter is expected but has not been found var.vt = VT_ERROR; var.scode = DISP_E_PARAMNOTFOUND; } if(!byref || var.vt == VT_ERROR) { VariantCopy(&r_rgvarg[i], &var); VariantClear(&var); } byref is true (it was set at line 911), and the parameter is [in] but it seems that that case isn't handled properly. It should pass a Variant with VT_ERROR and DISP_E_PARAMNOTFOUND. I'm not quite sure of how to fix this properly. Changing line 943 to this works fine: else if(byref) // here we filter the optional out params (treated below) But I didn't check if that breaks other calls.

I sent an email to the maintainer, Fabio Mascarenhas, at the time, but don't think I ever heard anything back. Cheers, Shaun
