之前一直不知道怎麼把這個記錄給刪掉，煩死了。可不能留下私密信息在這裡阿，就下載了Empathy源碼下來看一下檢查一下。好像Empathy的文檔沒有有，我沒仔細看，反正網上的文檔搜到的文檔說的位置是錯的，可能因為Empathy 更新了吧。
根據代碼，Empathy使用的是 Telepathy 框架，所以這個 聊天記錄使用的也是“Telepathy Logger”這個模塊來作的。Telepathy Logger的文檔在 http://telepathy.freedesktop.org/wiki/Logger ，提到
--------------
It stores its logs to
${XDG_DATA_HOME}/share/TpLogger
which usually expands to at
${HOME}/.local/share/TpLogger/
--------------------
我到我自己的 home 目錄 /home/widebright/.local/share/TpLogger/logs
下面一看，果然聊天記錄都在這裡，yahoo messager 和spark的記錄都保存在 帳號名字/聯繫人名字/聊天日期.log 這樣的子目錄的文件裡面，明文 的xml格式的。
我把把這下面的東西都清空了。然後在Empathy 裡面設置了不保存密碼。這下終於放心了。
看代碼的時候，發現這個Empathy的聊天記錄界面，還是用webkit來做的。很有意思，有的樹型節點的操作、顯示那些都是寫在html的javascript裡面，然後在gtk裡面調用的，很有意思。如果想在gtk窗口上面嵌入一個瀏覽器窗口作顯示的，也可以參考這個代碼吧。我之前就不知道這個webkit還能這樣用的。
