first script for mod_lua apache2.3/2.4

function handle(r)
	r.content_type = "text/html"
	--r.headers_out["X-Powered-By"] = "mod_lua; " .. _VERSION
	return apache2.OK

Mod lua expects a function with the name handle() else there is a 500 Error. The error handling is pretty anoying…

compile lua on windows

Grab the “newest” (2008)
unpack it. Compiling with VC++ is very easy.

Open the x64 %comspec% /E:ON /V:ON /T:0E /K “C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd” /Release
or x86 command line
%comspec% /k “”C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat”” x86

browse to lua folder and run

copy /y src\*.* .\

patch requires admin privileges on Windows 7

The patch.exe requires admin privileges on Windows 7. This is pretty annoying! The first thing that worked was just renaming the file to pach.exe Stupid windows. But I didn’t like that cause than I mostly typed it wrong and patch command was missing. I found a better solution:

Create a text file in the same directory with the name patch.exe.manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
 <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
 <requestedExecutionLevel level="asInvoker"/>

Save as UTF8. Now it works. Well I have to test if it is possible to embedd the manifest than good bye $%&# asking for admin permission

reverse proxy for utorrent part 2

In my last post about utorrent (µtorrent) I was frustrated that I wasn’t able to change the url from /gui/ to /tor/
Woot! In apache 2.3 which will be apache 2.4 and I think it will be released in early 2011 the proxy module is much better and there it works to have a different URL :-) Even as ALPHA or BETA version the new apache rocks a lot and runs stable. In condition with mod_fcgid it is real cool technology e.g. running PHP separated form apache that allows to run different PHP version of the server in vhosts or directories. Also running a non thread safe PHP version. Speed! IPv6 would be fine, but the offered patches are not applied to trunk :-/There is an annoying bug in mod_fcgid. I’m glad I found a fix for it (help from Tom Donovan and Sob).

Disable AllowOverride (htaccess to httpd.conf)

AllowOverride is one of the things that slow down a lot. Disabling it makes apache faster. It is a horror to migrate all .htaccess files by hand. BUT here is a PHP script from Paul Reinheimer which makes it realy easy :-)

Get it htaccess.php

tune your server!

Preparing mod_svn for compiling on windows

Well I didn’t manage it to compile mod_svn without the apache compiled source tree, but than it works fine and fast. Also Python 3 did not work. So I took 2.7
Assuming that OpenSSL 1.0.0a and zlib are compiled in that source tree as well.

C:\python27\python -t vcproj --vsnet-version=2008 --with-httpd=C:\build\httpd-2.2.x-sni-dev-ipv6
 --with-zlib=C:\build\httpd-2.2.x-sni-dev-ipv6\srclib\zlib --with-apr=C:\build\httpd-2.2.x-sni-dev-ipv6\srclib\apr

Than just open subversion_vcnet.sln with Visual C++ Express Edition. Ignore all warnings about solution folders. Choose the __ALL__ project. Than change from debug to release. Start!

My sample config

LoadModule dav_module modules/
LoadModule dav_fs_module modules/

LoadModule auth_digest_module modules/
LoadModule dav_svn_module modules/
LoadModule authz_svn_module modules/

<Location /svn/>
  DAV svn

  SVNListParentPath on
  SVNParentPath /Repositories/
  SVNIndexXSLT "/svnindex.xsl"
  SVNPathAuthz on
  AuthzSVNAccessFile "C:/Repositories/authz"

  AuthName "Subversion Repositories"
  AuthType Basic
  AuthUserFile "C:/Repositories/htpasswd"

  require valid-user
