• 由於把系統從 Etch 升級到 Lenny, Python 環境因而從 2.4 升級到 2.5, Trac 從 0.10 升級到 0.11, 不管是 trac 舊的設定檔以及 plugin 都不管用了。只好從頭把 Trac Plugin 重裝一次。
• 設定檔的部分：先用 trac-admin testbed initenv 產生一個全新的範本目錄，然後用 vimdiff 比對有哪些新參數要加進去。
• Plugin 部分：
  • 首先要注意的是 Trac 0.11 已經把 TracAccountManager 跟 TracWebAdmin 納入，因此不可以再裝，否則會有一堆錯誤。
  • ​Graphviz Plugin - 用 graphviz 語法畫圖的擴充套件

    $ w3m "http://trac-hacks.org/changeset/latest/graphvizplugin/0.11-0.7.4?old_path=/&filename=graphvizplugin/0.11-0.7.4&format=zip"
    $ unzip unzip graphvizplugin_0.11-0.7.4-r5537.zip
    $ cd graphvizplugin/0.11-0.7.4
    graphvizplugin/0.11-0.7.4$ sudo python setup.py bdist_egg
    graphvizplugin/0.11-0.7.4$ sudo easy_install dist/graphviz-0.7.4-py2.5.egg
    

  • ​WikiInclude - 讓用 [[WikiInclude(WikiStart)]] 語法來包含其他 Wiki 頁面中的內容

    $ wget "http://trac-hacks.org/attachment/wiki/WikiIncludePlugin/0.11.versions.tbz2?format=raw" -O wikiincludeplugin-0.11.tar.gz
    $ tar jxvf wikiincludeplugin-0.11.tar.gz
    $ cd 0.11
    0.11$ cat > setup.py << EOF
    from setuptools import setup
    
    PACKAGE = 'WikiInclude'
    VERSION = '0.2'
    DESCRIPTION = 'Page include plugin for Trac Wiki'
    
    setup(name=PACKAGE,
          version=VERSION,
          packages=['wikiinclude'],
          entry_points={'trac.plugins': ['wikiinclude.wikiinclude=wikiinclude.wikiinclude']})
    EOF
    0.11$ sudo python setup.py bdist_egg
    0.11$ sudo easy_install dist/WikiInclude-0.2-py2.5.egg
    

  • ​TracRedirect - 用 [[redirect(網址)]] 語法來作頁面自動轉址

    $ svn co http://svn.ipd.uka.de/repos/javaparty/JP/trac/plugins/redirect-0.11/
    $ cd redirect-0.11/
    redirect-0.11$ sudo python setup.py bdist_egg
    redirect-0.11$ sudo easy_install dist/TracRedirect-0.11.3.dev_r3272-py2.5.egg
    

  • ​Svnauthz File Administration Plugin - 用來管理誰有權限讀取 SVN 目錄的擴充套件

    $ svn co http://trac-hacks.org/svn/svnauthzadminplugin/0.11/ svnauthzadminplugin-0.11
    $ cd svnauthzadminplugin-0.11
    svnauthzadminplugin-0.11$ sudo python setup.py bdist_egg
    svnauthzadminplugin-0.11$ sudo easy_install dist/SvnAuthzAdminPlugin-0.1.2._Moved.to.Trac.0.11_-py2.5.egg

• 把 /usr/share/pyshared/trac/wiki/default-pages 搬到 /usr/share/pyshared/trac/wiki/default-pages.dpkg，只留下 RecentChanges、TitleIndex、WikiStart 三個預設頁面。

• 安裝 ​AccountManager 擴充套件

• 參考 2008-03-28 的紀錄，進行 Cloud 跟 Grid 兩個的 Ticket 攻擊清除。

  ~$ sudo sqlite3 /forge/trac_pool/cloud/db/trac.db

• 由於 0.11 版會把 Timeline 的日期用中文表示，因此如果要自訂 Timeline 顯示的話，會出現錯誤。可能程式邏輯還是衍用 2009-05-05 的格式，因此就在範本加入格式的字串，讓 Form 送出的日期字串可以符合程式邏輯。

  "2009年05月05日" is an invalid date, or the date format is not known. Try "YYYY年MM月DD日" instead.

• 安裝 ​piwik 來統計檔案下載次數

  # apt-get install php5-mysql php5-gd libsparkline-php mysql-server phpmyadmin
  # apache2ctl restart
  # cd /var/www/
  /var/www# wget http://piwik.org/latest.zip
  /var/www# unzip latest.zip
  /var/www# chown -R www-data:www-data piwik/
  

• 完成設定後，系統會告知如何把像 Google Analytics 的 javascript 加到 HTML 裡

  <!-- Piwik -->
  <script type="text/javascript">
  var pkBaseURL = (("https:" == document.location.protocol) ? "https://classcloud.org/piwik/" : "http://classcloud.org/piwik/");
  document.write(unescape("%3Cscript src='" + pkBaseURL + "piwik.js' type='text/javascript'%3E%3C/script%3E"));
  </script><script type="text/javascript">
  try {
  var piwikTracker = Piwik.getTracker(pkBaseURL + "piwik.php", 1);
  piwikTracker.trackPageView();
  piwikTracker.enableLinkTracking();
  } catch( err ) {}
  </script>
  <!-- End Piwik Tag -->
