Develop with git, on svn repository

With mplayer svn tree, for example.

1. Check out mplayer source
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

2.Init git
git init
git add .
git rm --cached -r .svn
git rm --cached -r */.svn
git rm --cached -r */*/.svn
...
git commit -a -c "svn 30936"

3.Coding and commit with git

4.git log

DKIM,Domainkey

Yahoo真的有在用。

 _domainkey.yahoo.com txt  "t=y\; o=~\; n=http://antispam.yahoo.com/domainkeys"

還不清楚他的格式,不過像我的。

netbsd._domainkey.netbsd.pfctl.info TXT "v=DKIM1\; g=*\; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDWv8fdQDN1FUJJxeZ6NMdOy8tAEwuTEzpsk1wYfxtYFwz1hHPiuOhF/KJSR2gvR8JuVAC92sI7RupEmBafscJdcqwepb2IVV+4GCZMNUfDpWtmXcoLQ+DZabZvpdlo9xLnZ5nR/oXiM00DlUlS2wI6nrF0Zf44Ib8eCJAo1x/+JQIDAQAB"

DNS record的格式是

selector._domainkey.domain
selector是在dkim-milter裡面指定的,可以有很多不同的selector,簽名的時候會標記說是用哪個selector簽名的。

DKIM,DomainKeys,SPF

之前有寫過SPF
現在發現Yahoo喜歡檢查DKIM/DomainKeys,這兩個好像是不一樣的東西啦,DKIM據說是Yahoo跟Cisco弄出來的。

跟SPF不一樣的就是,他是用來對發出去的郵件做簽章,沒有簽章的就是垃圾郵件。
public key則是放再dns的txt欄位。

目前還不是很清楚怎麼弄。
也不知道有誰家的郵件有加這個,yahoo自己也沒有。而且每封信都要驗證太麻煩了吧。那乾脆對身分驗證好了ksc91u@ksc91u.info 變成自己放一個txt ksc91u.at.ksc91u.info到dns去。

Build XNU Kernel

http://shantonu.blogspot.com/2009/09/mac-os-x-kernel-source-xnu-has-been.html

The Mac OS X kernel source (xnu) has been released for Mac OS X 10.6 Snow Leopard: here

Building xnu requires some open source (but not pre-installed) tools. Darwinbuild is the most reliable way for building these dependencies and xnu itself. Until that is ready, you can build the tools manually as follows:

1. Download the build tools source(s)
   
   $ curl -s -O http://www.opensource.apple.com/tarballs/cxxfilt/cxxfilt-9.tar.gz
   $ curl -s -O http://www.opensource.apple.com/tarballs/dtrace/dtrace-78.tar.gz
   $ curl -s -O http://www.opensource.apple.com/tarballs/kext_tools/kext_tools-177.tar.gz
   $ curl -s -O http://www.opensource.apple.com/tarballs/bootstrap_cmds/bootstrap_cmds-72.tar.gz
2. Unpack the tools
   
   $ tar zxf cxxfilt-9.tar.gz
   $ tar zxf dtrace-78.tar.gz
   $ tar zxf kext_tools-177.tar.gz
   $ tar zxf bootstrap_cmds-72.tar.gz
3. Build cxxfilt
   
   $ cd cxxfilt-9
   $ mkdir -p obj sym dst
   $ make install RC_ARCHS="i386 x86_64" RC_CFLAGS="-arch i386 -arch x86_64 -pipe" RC_OS=macos RC_RELEASE=SnowLeopard SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym DSTROOT=$PWD/dst
   ...
   $ sudo ditto $PWD/dst/usr/local /usr/local
   Password:
   $ cd ..
4. Build dtrace
   
   $ cd dtrace-78
   $ mkdir -p obj sym dst
   $ xcodebuild install -target ctfconvert -target ctfdump -target ctfmerge ARCHS="i386 x86_64" SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym DSTROOT=$PWD/dst
   ...
   $ sudo ditto $PWD/dst/usr/local /usr/local
   Password:
   $ cd ..
5. Build kext_tools
   
   $ cd kext_tools-177
   $ mkdir -p obj sym dst
   $ xcodebuild install -target kextsymboltool -target setsegname ARCHS="i386 x86_64" SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym DSTROOT=$PWD/dst
   ...
   $ sudo ditto $PWD/dst/usr/local /usr/local
   Password:
   $ cd ..
6. Build bootstrap_cmds
   
   $ cd bootstrap_cmds-72
   $ mkdir -p obj sym dst
   $ make install RC_ARCHS="i386" RC_CFLAGS="-arch i386 -pipe" RC_OS=macos RC_RELEASE=SnowLeopard SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym DSTROOT=$PWD/dst
   ...
   $ sudo ditto $PWD/dst/usr/local /usr/local
   Password:
   $ cd ..
7. Download the xnu source
   
   $ curl -s -O http://www.opensource.apple.com/tarballs/xnu/xnu-1456.1.26.tar.gz
8. Unpack xnu
   
   $ tar zxf xnu-1456.1.26.tar.gz
9. Build xnu
   
   $ cd xnu-1456.1.26
   $ make ARCH_CONFIGS="I386 X86_64" KERNEL_CONFIGS="RELEASE"
   ...
   $ file BUILD/obj/RELEASE_*/mach_kernel
   BUILD/obj/RELEASE_I386/mach_kernel: Mach-O executable i386
   BUILD/obj/RELEASE_X86_64/mach_kernel: Mach-O 64-bit executable x86_64
