很糟糕的作法..

#include <..\\..\\kernel\\oal\\debug.c>

所以若是用 function name : OEMInitDebugSerial 來search，
會找到 oal 下的 debug.c，而以為會 link oal libary...

使用close source 的東西真是浪費時間。
尤其是 close source part 既然有使用到外界定義的global variable (還很多)。
誰知道動了哪一個global variable 會讓那一部份fail 呀。

真是浪費時間

becuase it's C

typedef name "Addr" used in  expression context

這個error..

Addr 是typedef 的structure type。

error 的位置是...

static Addr LBAtoCHS(FlashInfo *pFlashInfo, Addr lba)
{
    if(lba.type == CHS)
        return lba;

    Addr chs;
    DWORD tmp = pFlashInfo->dwNumBlocks * pFlashInfo->wSectorsPerBlock;
...

結果...
錯誤的原因是..

這是 C，不是C++，所以所有變數都要先宣告在第一個expression 之前..

不懂為什麼這麼多人要定義 WORD，BYTE，DWORD...
直接用 unsigned short, char, unsigned long 不好嗎？

大家都要用自己的名子 (再加上模組化做得不好)，最後就是..

typedef short SHORT;
typedef long LONG;

typedef signed      char        INT8;
typedef unsigned    char        UINT8;
typedef signed      short       INT16;
typedef unsigned    short       UINT16;
typedef signed      int         INT32;
typedef unsigned    int         UINT32;

typedef unsigned char uchar;
typedef unsigned short ushort;
typedef unsigned int uint;
typedef unsigned long ulong;

typedef unsigned long ULONG;
typedef unsigned short USHORT;
typedef unsigned char UCHAR;

typedef unsigned long       DWORD;
typedef int                 BOOL;
typedef unsigned char       BYTE;
typedef unsigned short      WORD;

typedef int                 INT;
typedef unsigned int        UINT;

typedef short Int16;
typedef unsigned short UInt16;
typedef unsigned long  UInt32;
typedef unsigned char  UInt8;

#define     U32 unsigned int
#define     U16 unsigned short
#define     S32 int
#define     S16 short int
#define     U8  unsigned char
#define        S8  char

typedef    unsigned int    uint32;
typedef    unsigned short    uint16;
typedef    unsigned char    uint8;
typedef    signed int        int32;
typedef    signed short    int16;
typedef    signed char        int8;

他們沒有想過自己的code，有一天，會要和其他人的code一起工作嗎 ?

讓自己寫的code可以讓很多人方便的使用，不是比較好嗎？
還是自己寫得爽比較重要 ?

hg 啟動內建的 http server -- part II

繼續..

每個 repository 可以自行設定一些特徵.. web style.. authorization... zip download support ..
就是利用每個 repository 下 .hg 目錄裡的 hgrc 檔 (要自己 create)

以下就是為了方便所寫的 hgrc 內容..

[web]
style = gitweb
allow_archive = bz2 gz zip
push_ssl = false
allow_push = *

這是..

改用 git style 的 wen interface (比較詳細)。
增加 bz2, gz, zip 的source snapshoot 下載
不必用 ssl (因為不知道在windows command 下怎麼用 :P)
允許經由 http 作push 的動作 (可以讓別人 checkin)

MSDN Training Material : CE

MSDN 有一篇介紹 CE Device Driver 的pdf : http://www.academicresourcecenter.net/curriculum/pfv.aspx?ID=5578

雖然是 for CE .NET ，但是對CE 5.0 好像也適用。

這是一系列的文章 MSDN Training:

Module 7 的內容比較多。

VSS impoter - migrate from VSS to SVN

從 VSS import 到SVN 的工具 : SVNImporter

這是一個用java寫的opensource 的工具，可以將source repository 由 VSS 轉移到 SVN 。

方法好像是：將package解開，依照需要修改 config.properties。然後下command。

config.properties 裡面的sample 是以 windows 平台為例子的。

... 所以仔細來看，應該也不是真正 import VSS，因為 VSS中各revision 的checkin, out owner 資訊會喪失。

.. 大概是這樣吧，目前還沒正式run.

install java in Debian

sun-java 屬於 "non-free" ，所以要在 sources.list 中加入 "non-free"。

如果只是需要執行環境，就只需要安裝

sun-java6-jre
sun-java6-plugon
sun-java6-fonts

如果要寫java，要加裝

sun-java6-jdk

裝完後，command :

$java -version

看java版本。

java不是也GPL了嗎 ? 為甚麼還是在 "non-free" ?

svn http, user-password and access control

使用 http:// 作為svn 的 url，是利用 apache 的 dav_svn module。

dav 是 (distribution authorization and versioning ，是 http 協定的一個擴充)。

AuthUserFile  /etc/apache2/dav_svn.passwd
AuthzSVNAccessFile /etc/apache2/dav_svn.authz

所以

要先準備好這兩個file，並且 follow .conf 的內容，擺在對應的path 中
user-passwd file 的內容是用 htpasswd 操作的，add user, change password 都要用htpasswd 來作。
svn 下各個 folder 的access 權限就由 dav_svn.authz 設定。這個file 是plain text。

Add User :

htpasswd  'target .passwd file' user-name

這裡 'target.passwd file' 就是 /etc/apache2/dav_svn.passwd.

權限設定：

[/]
* =
guest = r
svntest = rw
charles-chang = rw

意思是對 [/] 目錄的權限設定：
* - 所有人 - 無法access
guest - 僅能讀取，無法修改
svntest, charles-chang 都是一般user，可以讀取，修改。

當然，要用htpasswd把 guest, svntest, charles-chang都加到 user-passwd file 中

僅能讀取的 user 一樣可以最 checkout，add file.. 但是在 commit 時會出現 error，svn log上也不會有該user的更動紀錄。

mod-python in apache2

安裝完 libapache2-mod-python 後，測試一下..

修改 /etc/apache2/httpd.conf 加入下面的部份 (測試完後，再刪掉)

<Location /mpinfo>
  SetHandler mod_python
  PythonInterpreter main_interpreter
  PythonHandler mod_python.testhandler
</Location>

reload apache2 ，或是用 a2enmod mod_python 將module load進來。

然後開啟 browser，網址 : http://10.1.1.152/mpinfo 就可以看到 python module info page。

11.10.2007

folder 方式 access subversion folder

在 svn-book 看到的。
在 Windows XP 中使用 file explorer 瀏覽 WebDAV folder。

據說是 XP 的bug。
在傳送 authorization 時，為一直用 Host\username，這是不符合 WebDAV規定的，所以會不成功。

所以在網路芳鄰中新增網路位置時，要把 port 寫上去..

http://host:80/repository
